D.	Risk Factors

This section contains forward-looking statements that are subject to the Cautionary Statement appearing on page 2 of this annual report. Risks to Sony are also discussed elsewhere in this annual report, including, without limitation in the other sections of this annual report referred to in the Cautionary Statement.

The coronavirus disease 2019

(COVID-19)

pandemic has adversely affected, and is expected to continue to adversely affect, Sony’s business operations, operating results and financial condition.

The COVID-19 pandemic is adversely affecting the production, development, sale and distribution of the products and services in each of Sony’s business segments, and this negative impact is expected to continue in the future. For example, in the Game & Network Services (“G&NS”) segment, there has been an adverse impact on the production of hardware due to issues in the component supply chain. In the Music segment, CDs and other packaged media sales are decreasing due to restrictions on going outside, and ticket, merchandising and video revenues are decreasing as concerts and other events are being postponed and cancelled in Japan and other areas. In the Pictures segment, box office revenue has been impacted by the closure of movie theaters around the world, and Sony generally has not been able to release its already completed titles in theaters. In the Electronics Products & Solutions (“EP&S”) segment, certain of Sony’s manufacturing sites ceased production for a period of time pursuant to local government policy, and a portion of supply continues to be insufficient to meet demand. Additionally, some partner companies that supply components to several of Sony’s businesses have reduced their operations, causing a delay in the production of some Sony products due to component shortages.

In the Financial Services segment, pursuant to the announcement of a state of emergency by the Japanese government, all

in-person

sales activity of the Lifeplanner

®

salespeople at Sony Life Insurance Co., Ltd. (“Sony Life”) was suspended from April 2020 to May 2020. The impact that these and other

COVID-19-related

factors have had on Sony’s ability to produce, develop, sell and distribute the products and services of each of Sony’s business segments is further discussed in “Item 5.

Operating and Financial Review and Prospects.

”

The timing and extent to which the pandemic further negatively impacts Sony’s business could vary greatly depending on future developments, such as the possible further spread of or a resurgence in

COVID-19,

as well as the state of lockdowns and other measures in various geographic areas around the world. For example, in the G&NS segment, hardware production and game software development could continue to be delayed due to the impact of

COVID-19.

The Music segment may continue to be negatively impacted by delays in the release of new music and a global reduction in advertising licensing revenue, and the Pictures segment may continue to be negatively impacted by delays in the production and release schedules of new motion pictures and TV shows, as well as by the global reduction in advertising revenue. The EP&S segment could continue to be adversely impacted by factory shutdowns and supply chain issues, and by the closure of retail stores globally. The Imaging & Sensing Solutions (“I&SS”) segment may be negatively impacted by a decline in demand in the smartphone market, and the Financial Services segment may continue to be negatively affected by the prohibition against all

in-person

sales activity of the Lifeplanner

®

salespeople at Sony Life.

The continued impact of

COVID-19

could heighten many of the risks and uncertainties noted below.

Sony must overcome increasingly intense competition, which could lead to lower revenue or operating margins.

Sony has several business segments in different industries with many product and service categories, which cause it to compete with many existing and new competitors ranging from large multinational companies to highly specialized entities that focus on only one or a few businesses and also, potentially, with outsourced manufacturing service partners that currently supply products to Sony. These competitors may have greater financial, technical, labor and marketing resources available to them than those available to Sony. Sony’s financial condition and operating results depend on its ability to efficiently anticipate and respond to these established and new competitors.

The competitive factors Sony faces vary depending on the nature of the business. For example, Sony’s electronics businesses compete on the basis of various factors including price and function, while Sony’s Music and Pictures businesses compete for talent, such as artists, songwriters, actors, directors and producers, and for entertainment content that is created, acquired, licensed and/or distributed. Competition on price can lead to lower margins when costs do not fall at a proportional rate, and competition for talent and appealing product can also lead to lower profitability if the higher costs required for such talent and content cannot be recouped through greater sales. Moreover, even for those products where Sony believes it has a strong competitive advantage, such as image sensors, it is possible that its competitors’ technological capabilities will accelerate such that Sony would be unable to maintain its advantageous market position. In its consumer electronics businesses, to produce

7

---

Table of Contents

products that appeal to changing and increasingly diverse consumer preferences or to overcome the fact that a relatively high percentage of consumers already possess similar products, Sony must develop superior technology, anticipate consumer tastes and rapidly develop attractive and differentiated products with competitive prices and features. Sony faces increasingly intense pricing pressure from competitors, retailer consolidation, new sales/distribution channels and shorter product cycles in a variety of consumer product categories. In the Music and Pictures segments, operating results can be impacted by worldwide consumer acceptance of their products, which is difficult to predict, by competing products released at or near the same time and by alternative forms of entertainment and leisure activities available to consumers. Additionally, the spread of

COVID-19

starting in the beginning of the 2020 calendar year resulted in lockdowns around the world, which are influencing changes in consumer behavior.

If Sony is unable to maintain its advantageous market position in the fields in which it has a technological or other competitive advantage, Sony is unable to effectively anticipate and counter the ongoing price erosion that frequently affects its consumer products or the cost pressures affecting its businesses, there is a change in existing business models or consumer preferences, or the average prices of Sony’s products decrease faster than Sony is able to reduce manufacturing costs, Sony’s operating results and financial condition may be adversely impacted.

To remain competitive and stimulate customer demand, Sony must invest in research and development to achieve product and service innovations and successfully manage frequent introductions of such new products and services.

To strengthen the competitiveness of its products and services, Sony continues to invest in research and development (“R&D”), particularly in growth areas such as image sensors and the G&NS segment. However, Sony may not be successful in investing in R&D if it fails to identify products, services and market trends with significant growth potential. In addition, Sony’s investments may not yield the innovation or the expected results quickly enough, or competitors may lead Sony in technological innovation. This may hinder Sony’s ability to commercialize new and competitive products and services.

In the consumer electronics, network services and smartphone businesses, Sony must continually introduce, enhance and stimulate customer demand for products and services. Sales of these products and services are particularly sensitive to the significant weighting of consumer demand to the

year-end

holiday season. In Sony’s G&NS segment, the successful introduction and penetration of gaming platforms, including streaming, is a significant factor driving sales and profitability, and this success is affected by the ability to provide customers with attractive software

 line-ups

and online services. However, there is no assurance that third-party software developers and publishers, major contributors to this effort, will continue to develop and release software. In addition, Sony believes that integrating its hardware, software, entertainment content and network services, and investing in R&D to effect such integration, is essential in generating revenue growth and profitability. However, this strategy depends on its ability to further develop network services technologies, coordinate and prioritize strategic and operational issues among Sony’s various business units and sales channels, continually introduce enhanced and competitively priced hardware that is seamlessly connected to network platforms with user interfaces that are innovative and attractive to consumers and also standardize technological and interface specifications industry-wide and across Sony’s networked products and business units. In addition, the G&NS, Music and Pictures segments must invest substantial amounts, which may include significant upfront investments, in internally developed software titles, artist advances, catalog acquisitions, motion picture productions, television productions and broadcast programming before knowing whether their products will receive customer acceptance. Furthermore, underperformance of Pictures’ products in the initial distribution market is correlated with weak performance in subsequent distribution markets, which would have an adverse effect on Sony’s results in the year of initial release as well as future years.

The successful introductions of, and transitions to, new products and services depend on a number of factors, such as the timely and successful completion of development efforts, market acceptance, planning and executing an effective marketing strategy, managing new product introductions, managing production

ramp-up

issues, the availability of application software for new products, quality control and the concentration of consumer demand in the

year-end

holiday season. If Sony cannot achieve the expected results from its investment in R&D, adequately manage frequent introductions of new products and services and obtain consumer acceptance of its new products and services, or if Sony is not successful in implementing its integration strategy, Sony’s reputation, operating results and financial condition may be adversely impacted.

Table of Contents

Sony’s strategic initiatives, including acquisitions, joint ventures, investments, capital expenditures and restructurings, may not be successful in achieving their strategic objectives.

Sony actively engages in acquisitions, joint ventures, capital expenditures and other strategic investments to acquire new technologies, efficiently develop new businesses and enhance its business competitiveness. For example, on November 18, 2019, Sony acquired the entirety of the remaining 42% equity interest it did not already own in Game Show Network, LLC (“Game Show Network”), making Game Show Network a wholly-owned subsidiary of Sony.

When making acquisitions, Sony’s financial results may be adversely affected by the significant cost of the acquisition and/or integration expenses, failure to achieve synergies, failure to generate expected revenue and cost improvements, loss of key personnel and assumption of liabilities.

When establishing joint ventures and strategic partnerships, Sony’s financial and operating results may be adversely affected by strategic or cultural differences with partners, conflicts of interest, failure to achieve synergies, additional funding or debt guarantees required to maintain the joint venture or partnership, requirements to buy out a joint venture partner, sell its shares or dissolve a partnership, insufficient management control including control over cash flow, loss of proprietary technology and

know-how,

impairment losses and reputational harm from the actions or activities of a joint venture that uses the Sony brand.

Sony invests heavily in production facilities and equipment, including fabrication facilities used to make image sensors for smartphones and other products. Sony may not be able to recover these capital expenditures in part or full or in the planned timeframe due to the competitive environment, lower-than-expected consumer demand or changes in the financial condition or business decisions of Sony’s major customers. Sony invested 128.9 billion yen and 265.7 billion yen of capital in the fiscal years ended March 31, 2019 and 2020, respectively, mainly for the purpose of increasing image sensor production capacity.

Further, Sony is implementing restructuring and transformation initiatives to enhance profitability, business autonomy and shareholder value and to clearly position each business within the overall business portfolio. For example, Sony transferred its battery business to Murata Manufacturing Co., Ltd. Group in the fiscal year ended March 31, 2018. However, the expected benefits of these initiatives, including the expected level of profitability, may not be realized due to internal and external impediments or market conditions worsening beyond expectations. If Sony is not successful in achieving its restructuring and transformation initiatives, Sony’s operating results, financial condition, reputation, competitiveness or profitability may be adversely affected. Sony incurred restructuring charges in the amount of 22.4 billion yen, 33.1 billion yen and 25.0 billion yen in the fiscal years ended March 31, 2018, 2019 and 2020, respectively.

Sony’s sales and profitability may be affected by the operating performance of wholesalers, retailers, other resellers and third-party distributors.

Sony is dependent for the distribution of its products on wholesalers, retailers, other resellers and third-party distributors, many of whom also distribute competitors’ products. For example, in some cases, Sony’s smartphones sold through cellular network carriers are subsidized by the carriers. There is no assurance that such subsidies will be continued at all or in the same amounts upon renewal of Sony’s agreements with these carriers or in agreements Sony enters into with new carriers. In addition, the Pictures segment depends on third parties to theatrically exhibit its motion pictures, and to operate cable, satellite, internet and other distribution systems to distribute its motion pictures and television programming; a decline in the licensing fees received from these third parties may adversely affect the Pictures segment’s sales. The Pictures segment’s worldwide television networks are also distributed on third-party cable, satellite and other distribution systems and the failure to renew, or renewal on less favorable terms of, television carriage contracts (broadcasting agreements) with these third-party distributors may adversely affect the Pictures segment’s ability to generate advertising and subscription sales through these networks.

Sony invests in programs to incentivize wholesalers, retailers, and other resellers and third-party distributors to position and promote Sony’s products, but there is no assurance that these programs will provide a significant return or incremental revenue by persuading consumers to buy Sony products instead of competitors’ products.

The operating results and financial condition of many wholesalers, retailers, other resellers and third-party distributors have been adversely impacted by competition, especially from online retailers, and weak economic conditions. If their financial condition continues to weaken, they stop distributing Sony’s products, or uncertainty regarding demand for Sony’s products or other factors cause them to reduce their ordering, marketing, subsidizing, or distributing Sony’s products, Sony’s operating results and financial condition may be adversely

impacted. For example, starting in the beginning of the 2020 calendar year, the spread of

COVID-19

led to the closure of retail stores and other businesses globally which is negatively impacting sales of Sony’s products.

As a global company, Sony is subject to a wide range of laws and regulations and a growing consumer focus on corporate social responsibility in many countries. Those laws and regulations, as well as consumer focus, might change in significant ways, leading to an increase in the costs of Sony’s operations, a curtailment of Sony’s activities, and/or an adverse effect on Sony’s reputation.

As a global company, Sony is subject to the laws and regulations of many countries throughout the world that affect its business operations in a number of areas, including advertising, promotions, consumer protection, import and export requirements, anti-corruption, anti-competition, environmental protection, privacy, data protection, content and broadcast regulation, labor, taxation, foreign investment, government procurement, foreign exchange controls, and economic sanctions, as well as laws relating to the collection, use, retention, security and transfer of personally identifiable information.

Compliance with these laws and regulations may be onerous and expensive. These laws and regulations continue to develop and may be inconsistent from jurisdiction to jurisdiction, further increasing the cost of compliance and doing business. Any such developments could occur frequently and without warning, and could make Sony’s products or services less attractive to its customers, delay or prohibit introduction of new products or services in one or more regions or cause Sony to change or limit its business practices. For example, imposition of restrictive trade measures in the United States and elsewhere, as well as retaliatory actions against such measures, could result in increased customs duties applicable to Sony’s products or increased costs for procuring parts and components, and could limit or prohibit the sales of Sony’s products and services to certain of its current or potential customers, which may adversely affect Sony’s operating results and financial condition. In addition, changes in laws or regulations or the judicial interpretation thereof that Sony relies on or Sony is subject to in conducting its operations, including online operations, as well as Sony’s failure to anticipate such changes, may subject Sony to greater risk of liability, increase the costs of compliance, or limit Sony’s ability to engage in or expand certain operations or lead to discontinuance of certain operations.

Violation of applicable laws or regulations by Sony, its employees, third-party suppliers, business partners and agents may subject Sony to fines, penalties, legal judgments, restrictions on business operations and/or reputational damage. Additionally, there is a growing global regulatory and consumer focus on corporate social responsibility and sourcing practices and increasing regulatory obligations of public disclosure regarding these matters. In particular, there is increased attention on labor practices, including work environments at electronic component manufacturers and original design manufacturing/original equipment manufacturing, or ODM/OEM, product manufacturers operating in Asia. Increased regulation or public pressure in this area could cause Sony’s compliance costs to increase, particularly since Sony uses many parts, components and materials to manufacture its products and relies on suppliers to provide these parts, components and materials but does not directly control the suppliers’ procurement or employment practices. A finding of

 non-compliance,

 or the perception that Sony has not responded appropriately to growing consumer concern for such issues, whether or not Sony is legally required to do so, may adversely affect Sony’s reputation, operating results and financial condition.

Sony must manage its large volume of and widespread procurement from third-party suppliers and business partners to control inventory levels, availability, costs and quality of parts, components, software and network services within volatile markets.

Sony’s products and services rely on a large volume of third-party suppliers and business partners for parts, components, software and network services, including semiconductors, chipsets for PlayStation game consoles and mobile products, LCD (liquid crystal display) panels and the Android OS that is used in mobile products, televisions and services. External suppliers’ and partners’ shortages, fluctuations in pricing, quality issues, discontinued support, changes in business terms or prioritization of customers outside the electronics sector or of Sony’s competitors can adversely affect Sony’s operating results, brand and reputation. Reliance on third-party software and technologies may make it increasingly difficult for Sony to differentiate its products from competitors’ products. Also, shortages or delayed shipments of critical parts or components may result in a reduction or suspension of production at Sony’s or its business partners’ manufacturing sites, particularly where Sony is substantially reliant on one supplier, where there is limited production capacity for custom parts or components, or where there are initial manufacturing capacity constraints for products, parts or components that use new technologies.

Sony places orders for parts and components in line with production and inventory plans determined in advance based on its forecast of consumer demand, which is highly volatile and difficult to predict. Inaccurate

10

Table of Contents 

forecasts of consumer demand or inadequate business planning can lead to a shortage or excess inventory, which can disrupt production plans and result in lost sales opportunities or inventory adjustments, respectively. Sony writes down the value of its inventory when the underlying parts, components or products have become obsolete, when inventory levels exceed the amount expected to be used, or when the value of the inventory is otherwise recorded at a value higher than net realizable value. Such lost sales opportunities, inventory adjustments, or shortages of parts and components have had and may have an adverse impact on Sony’s operating results and financial condition.

Sony’s sales, profitability and operations are sensitive to global and regional economic and political trends and conditions.

Sony’s sales and profitability are sensitive to economic trends in its major markets. In the fiscal year ended March 31, 2020, 29.9%, 22.6% and 20.6% of Sony’s sales and operating revenue were attributable to Japan, the U.S. and Europe, respectively. These markets may be subject to significant economic downturns, resulting in an adverse impact on Sony’s operating results and financial condition. An actual or expected deterioration of economic conditions in any of Sony’s major markets may result in a decline in consumers’ consumption and adverse impacts on the businesses of commercial customers, resulting in reduced demand for Sony’s products and services. For example, in the Pictures segment, a general decline in the economy may result in decreased overall spending within the advertising market and a decline in television networks’ ability to generate revenues, which could result in lower advertising revenues for Sony’s own networks and lower license fees paid by

third-party

networks for Sony’s content, which may adversely affect the Pictures segment’s revenues.

In addition, Sony’s operations are conducted in many countries and regions around the world, and these international operations, particularly in certain emerging markets, can create challenges. For example, in Sony’s electronics businesses and the G&NS segment, production and procurement of products, parts and components in China and other Asian countries and regions increase the time necessary to supply products to other markets worldwide, which can make it more difficult to meet changing customer demand in a timely manner. Further, in certain countries and regions, Sony may encounter difficulty in planning and managing operations due to unfavorable political or economic factors, such as armed conflicts, deterioration in foreign relations, changes in trade policies,

non-compliance

 with expected business conduct and a lack of adequate infrastructure. If international or domestic political and military instability disrupts Sony’s business operations or those of its business partners Sony’s operating results and financial condition may be adversely affected.

Foreign exchange rate fluctuations can affect Sony’s operating results and financial condition.

Sony’s operating results and financial condition are sensitive to foreign exchange rate fluctuations because many of Sony’s products are sold in countries other than the ones in which they were developed and/or manufactured. For example, within Sony’s electronics businesses, research and development and headquarters’ overhead costs are incurred mainly in yen, and manufacturing costs, including material costs, costs of procurement of parts and components, and costs of outsourced manufacturing services, are incurred mainly in the U.S. dollar and yen. Sales are dispersed and recorded in Japanese yen, the U.S. dollar, euro, Chinese renminbi, and local currencies of other areas, including emerging markets. Consequently, foreign exchange rate fluctuations have had and may have an adverse impact on Sony’s operating results, especially when the yen or the euro weaken significantly against the U.S. dollar, when the yen strengthens significantly against the euro, or when the U.S. dollar strengthens against emerging market currencies. Sony’s operating results may also be adversely impacted by foreign exchange rate fluctuations since Sony’s consolidated statements of income are prepared by translating the local currency denominated operating results of its subsidiaries around the world into yen. Furthermore, as Sony’s businesses have expanded in China and other areas, including emerging markets, the impact of fluctuations of foreign currency exchange rates in these areas against the U.S. dollar and yen has increased.

 Mid-

 to long-term changes in exchange rate levels may interfere with Sony’s global allocation of resources and hinder Sony’s ability to engage in research and development, procurement, production, logistics, and sales activities while maintaining profitability.

Although Sony seeks to reduce its exposure to foreign exchange risk by hedging a portion of its net short-term foreign currency exposure shortly before the transactions occur, such hedging activity may not offset any, or only a portion, of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place.

Moreover, since Sony’s consolidated balance sheet is prepared by translating the local currency denominated assets and liabilities of its subsidiaries around the world into yen, Sony’s equity capital may be adversely impacted when the yen strengthens significantly against the U.S. dollar, the euro and/or other foreign currencies.

Ratings downgrades or significant volatility and disruption in the global financial markets may adversely affect the availability and cost of Sony’s funding.

Sony’s credit ratings may be adversely impacted by unfavorable operating results and a decline in its financial condition. Any credit rating downgrades may, in turn, result in an increase in Sony’s cost of funding and may have an adverse impact on Sony’s ability to access commercial paper or

 mid-

 to long-term debt markets on acceptable terms.

Additionally, global financial markets may experience significant levels of volatility and disruption, generally putting downward pressure on financial and other asset prices and impacting credit availability. Historically, Sony’s primary sources of funds have been cash flows from operations, the issuance of commercial paper and other debt securities, such as term debt, as well as borrowings from banks and other institutional lenders. There can be no assurance that such sources will continue to be available on acceptable terms or be sufficient to meet Sony’s needs.

As a result, Sony may seek other sources of financing to fund operations, such as the draw-down of funds from contractually committed lines of credit from financial institutions or the sale of assets, in order to repay commercial paper and

 mid-

 to long-term debt as they become due, and to meet other operational and liquidity needs. However, such funding sources may also not be available at acceptable terms or be sufficient to meet Sony’s requirements. As a result, Sony’s operating results, financial condition and liquidity may be adversely affected.

Sony’s success depends on the ability to recruit, retain and maintain productive relations with highly skilled personnel.

In order to continue to develop, design, manufacture, market, and sell products and services, in increasingly competitive markets, Sony must attract, retain and maintain productive relations with key personnel, both internally and externally, including its executive team, other management professionals, creative talent and other highly skilled employees such as hardware and software engineers. However, such key personnel are in high demand. In addition, business divestitures, restructuring or other transformation initiatives may lead to an unintended loss of experienced human resources or

 know-how.

Actual or threatened work slowdowns or stoppages related to unionized workers, particularly in the entertainment businesses, could lead to delayed releases or cost increases. If these incidents occur or if Sony is unable to attract, retain and maintain productive relations with its highly skilled employees and key management professionals, Sony’s operating results and financial condition may be adversely affected.

Sony’s intellectual property might be subject to unauthorized use or theft and it might encounter restrictions in its use of intellectual property owned by third parties.

Sony’s intellectual property relating to Sony’s products and services, including those of the electronics businesses, such as image sensors, might be subject to unauthorized use or theft. For example, digital technology, the availability of digital media, and global internet penetration impact Sony’s ability to protect its copyrighted content from unauthorized duplication, digital theft and counterfeiting, putting pressure on legitimate product sales. Sony has incurred and will continue to incur expenses to help protect its intellectual property rights; however, Sony’s various initiatives to prevent such unauthorized use or theft of intellectual property might not achieve their intended result, which could adversely affect Sony’s competitive position and the value of its investment in R&D. Additionally, Sony’s intellectual property rights may be challenged or invalidated, or such intellectual property rights may not be sufficient to provide Sony with competitive advantages.

Many of Sony’s products and services are designed under the license of patents and other intellectual property rights owned by third parties. Based upon past experience and industry practice, Sony believes it will be able to obtain or renew licenses relating to various intellectual property rights that its business needs in the future; however, such licenses may not be available at all or on acceptable terms, and as a consequence Sony may need to redesign or discontinue its marketing, selling or distribution of such products or services.

Claims have been and may be asserted against Sony that its products or services, including third-party parts, components, software and network services used in Sony’s products or services, infringe the intellectual property rights of other parties. Such claims may be asserted by competitors or by other rights holders, particularly as products and services evolve to include new technologies and enhanced functionality. Such claims might require Sony to enter into settlement or license agreements, pay significant damage awards, face an injunction or refrain from marketing, selling or distributing certain of its products and services.

The failure to prevent unauthorized use or theft of Sony’s intellectual property rights, the failure to enter into licenses for necessary third-party intellectual property rights, the invalidation of Sony’s intellectual property rights or the settlement of an infringement claim against Sony by others may adversely impact Sony’s reputation, operating results and financial condition.

Changes in consumer behavior resulting from new technologies and distribution platforms, as well as increasing concentration of digital music distributors and creation of content by distributors themselves, may adversely affect operating results in Sony’s Music and Pictures segments.

Technology, particularly digital technology, used in the Music and Pictures segments continues to evolve, rapidly leading to alternative methods for the delivery, consumption and storage of digital content. These technological advancements have changed consumer behavior and empowered consumers to seek more control over when, where and how they consume digital content.

The prevalence of enhanced internet capabilities and other new media may continue to reduce the demand for packaged physical media and impact traditional television and

in-theater

motion picture viewership, which could negatively affect revenues from Sony’s Pictures segment.

Furthermore, as more music and video content is consumed over digital streaming networks, digital music distributors are becoming increasingly concentrated, which may decrease competition for Sony’s music content and adversely affect its pricing. In addition, digital music and video distributors may increase the amount of content they create for their own services, which may reduce the demand for content created or produced by Sony’s entertainment businesses. If Sony is unable to adequately respond to these changes or fails to effectively adapt to new market changes, Sony’s operating results and financial condition may be adversely impacted.

Changes in the regulation and performance of financial markets may adversely affect the operating results and financial condition of Sony’s Financial Services segment.

Sony’s Financial Services segment operates in industries subject to comprehensive regulation and supervision, including the Japanese insurance and banking industries. Future developments or changes in laws, regulations or policies may lead to increased compliance costs or limitations on operations in the Financial Services segment. In addition, Sony Corporation’s ability to receive funds from its affiliate Sony Financial Holdings Inc. in the form of financial support or loans is restricted by guidelines issued by regulatory agencies in Japan.

Changes in interest rates, foreign exchange rates and the value of Japanese government and corporate bonds, U.S. treasury bonds, equities, real estate and other asset classes may have an adverse effect on the operating results and financial condition of the Financial Services segment. For example, the life insurance business has invested most of its general account assets in ultra-long-term Japanese government and corporate bonds, as well as ultra-long-term U.S. treasury bonds, to match the liability characteristics of the long-term maturity insurance policies it has underwritten. The life insurance business has guaranteed yields on outstanding policies while its investment portfolio could be reduced by the market changes discussed above. The banking businesses have invested most of their total loan balance, or over half of their total assets, in their mortgage loans account. An increase in

non-performing

loans or a decline in prices of the real estate collateral from the market changes discussed above or deterioration of credit quality may have an adverse effect on operating results and financial condition through an increase in the allowance for doubtful accounts.

The market changes discussed above, Sony’s management of these changes or the occurrence of earthquakes, pandemic disease or other catastrophic events in Japan could expose the life and

non-life

insurance businesses to increasing costs or adverse impact on their ability to meet policy commitments.

The insurance businesses’ policy reserves and deferred insurance acquisition costs are calculated based on many actuarial assumptions that are uncertain. Significant differences between these actuarial assumptions and actual situations may result in additional policy reserves being recorded and the accelerated amortization of deferred acquisition costs, through the changes of calculation assumptions. In particular, the insurance businesses calculate policy reserves and deferred insurance acquisition costs based on the actuarial assumptions, assuming the future schedule of insurance premium revenue, yield of investments, claims to be paid for occurrence of insured events and other factors. The review of these actuarial assumptions is required at least once in each fiscal year.

Sony’s facilities and operations are subject to damage and disruption as a result of catastrophic disasters, outages or similar events that could lead to supply chain, manufacturing and other business disruptions and have an adverse impact on Sony’s operating results.

Sony’s headquarters and many of Sony’s most advanced device manufacturing facilities, including those for semiconductors, are located in Japan, where the risk of earthquakes is relatively high. A major earthquake in Japan, especially in Tokyo, the Tokai area or the Kyushu and Tohoku areas, where Sony headquarters, certain product manufacturing sites and semiconductor manufacturing sites, respectively, are located, could cause substantial damage to Sony’s business operations, including damage to buildings, machinery, equipment and inventories, and the interruption of production at manufacturing facilities. For example, the earthquake of April 14, 2016 and subsequent earthquakes in the Kumamoto region in Japan caused damage to a semiconductor manufacturing site in Kyushu, which interrupted production at the site.

In addition, offices and facilities used by Sony, its suppliers, service providers and business partners, including those used for raw materials, parts, components, network, telecommunications and information systems infrastructure, R&D, material procurement, manufacturing, motion picture and television production, logistics, sales, and online and other services are located throughout the world and are subject to possible destruction, temporary stoppage or disruption as a result of unexpected catastrophic events such as natural disasters, pandemic diseases, terrorist attacks, large-scale power outages and large-scale fires. If any of these facilities or offices were to experience a significant loss as a result of any of the above events, it may disrupt Sony’s operations, delay design, development or production, interrupt shipments and postpone the recording of sales, and/or result in large expenses to repair or replace these facilities or offices. For example, starting in the beginning of the 2020 calendar year, production delays for a portion of Sony’s products occurred due to temporary shutdowns and reduced operations at

in-house

manufacturing plants, factories to which Sony outsources and at Sony’s third-party suppliers, as a result of the spread of

COVID-19.

Sony may also be exposed to price increases for raw materials, parts and components, and lower demand from commercial customers. These situations may have an adverse impact on Sony’s operating results and financial condition.

Sony’s brand image, reputation and business may be harmed and Sony may be subject to legal claims if there is a breach or other compromise of Sony’s information security or that of its third-party service providers or business partners.

Sony, its third-party service providers, suppliers and other business partners make extensive use of information technology to support business operations, and to provide network and online services to customers. These operations and services, as well as Sony’s business information, may be intentionally or inadvertently compromised by malicious third parties, including state-sponsored organizations, criminal organizations, Sony employees, third-party service providers or other business partners. Such organizations or individuals may use a variety and combination of techniques, such as installing malicious software, exploiting vulnerabilities in information technology, using social engineering to mislead employees and business partners into disclosing passwords and sensitive information, and coordinating distributed

denial-of-service

attacks to render services unavailable. As cyber-attacks become increasingly sophisticated and automated, and as tools and resources become more readily available, there can be no guarantee that Sony’s actions, security measures and controls designed to prevent, detect or respond to intrusion, to limit access to data, to prevent loss, destruction, alteration, or exfiltration of business information, or to limit the negative impact from such attacks can provide absolute security against compromise. As a result, Sony’s business information, including personal information, may be lost, destroyed, disclosed, misappropriated, altered, or accessed without consent, and Sony’s information technology systems or operations, or those of its service providers or other business partners, may be disrupted. Malicious adversaries may also use unauthorized access to Sony’s networks as a platform to compromise Sony’s third-party business partners without Sony’s knowledge. Sony has previously been the subject of sophisticated and targeted attacks. For example, in the fiscal year ended March 31, 2015, Sony’s Pictures segment was subject to a cyber-attack that resulted in unauthorized access to, and theft and disclosure of, Sony business information, including employee information and other information, and the destruction of data. Additionally, Sony’s network services, online game businesses and websites have been subject to cyber-attacks by groups and individuals with a range of motives and expertise, resulting in unauthorized access, denial of service, and the theft and/or disclosure of customer information.

Any of the above incidents can result in significant remediation costs. In addition, a disruption to Sony’s network and online services, information technology, or other compromise of its information security may have serious consequences to its business and operations, including lost revenues, damage to relationships with business partners and other third parties, disclosure, alteration, destruction or use of proprietary information and the failure to retain or attract customers. Moreover, such disruptions and breaches may result in a diversion of

14

---

Table of Contents

management’s attention and resources. Further, it may result in adverse media coverage, which may harm Sony’s brand image and reputation. Sony may also be subject to legal claims or legal proceedings, including regulatory investigations and actions. Sony’s cyber insurance may not cover all expenses and losses and, accordingly, such breaches or other compromises of Sony’s information security or that of its third-party service providers or business partners may have an adverse impact on Sony’s operating results and financial condition.

Sony’s business may suffer as a result of adverse outcomes of litigation and regulatory actions.

Sony faces the risk of litigation and regulatory actions in different countries in connection with its operations. Legal proceedings, including regulatory actions, may seek to recover very large indeterminate amounts or to limit Sony’s operations, and the possibility that they may arise and their magnitude may remain unknown for substantial periods of time. For example, legal proceedings, including regulatory actions, may result from antitrust scrutiny of market practices for anti-competitive conduct. A substantial legal liability or adverse regulatory outcome and the substantial cost to defend the litigation or regulatory actions may have an adverse effect on Sony’s reputation, operating results and financial condition.

Sony is subject to financial and reputational risks due to product quality, product security, and liability issues.

Sony’s products and services, such as consumer products,

 non-consumer

 products, parts and components, semiconductors, software and network services are becoming increasingly sophisticated and complicated as rapid advancements in technologies occur and as demand increases for mobile products and online services. Also, many Sony products are connected to the internet, and regularly communicate with services provided by Sony or third parties.

Sony’s efforts to adapt to rapid advancements in technologies and increased demand for mobile products and online services, while also maintaining product quality and product security, may not be successful and may increase exposure to product liability. As a result, Sony may incur both reputational damages and expenses in connection with, for example, product recalls and after-sales services. In addition, Sony may not be successful in introducing after-sales upgrades, enhancements or new features to existing products and services, or in enabling existing products and services to continue to conveniently and effectively integrate with other technologies and online services. Moreover, cyber-attacks targeting internet-connected products have increased significantly. For example, customer information and Sony or third-party technical information may be misappropriated, the functionality of Sony’s products and services may be impaired, or Sony products may be used in

denial-of-service

attacks. There can be no guarantee that Sony’s security measures will prevent products from being compromised.

As a result, the quality of Sony’s existing products and services may not remain satisfactory to consumers and become less marketable, less competitive or obsolete, and Sony’s reputation, operating results and financial condition may be adversely affected. Moreover, allegations of security vulnerability, health and safety issues related to Sony products, or lawsuits related to product quality, health issues arising from products or product safety, regardless of merit, may adversely impact Sony’s operating results and financial condition, either directly or as a result of the impact on Sony’s brand image and reputation as a producer of high-quality products and services. These issues are relevant to Sony products sold directly to customers, whether manufactured by Sony or a third party, and also to products of other companies that are equipped with Sony’s components, such as semiconductors.

Sony’s financial results and condition may be adversely affected by its employee benefit obligations.

Sony recognizes an unfunded pension obligation for its defined benefit pension plans based on (i) the Projected Benefit Obligation (“PBO”) under each pension plan less (ii) the fair value of the pension plan’s assets, in accordance with the accounting guidance for defined benefit plans. Any decrease of the pension plan asset value or increases in the PBO due to a lower discount rate and changes in certain other actuarial assumptions may increase the unfunded pension obligations and may have an adverse effect on Sony’s financial results and condition.

Also, Sony’s financial results and condition could be adversely affected by future pension funding requirements pursuant to the Japanese Defined Benefit Corporate Pension Plan Act (“Act”). Under the Act, Sony is required to conduct a periodic actuarial revaluation and to ascertain whether certain financial criteria have been met after the annual accounting closing. In the event that the fair value of pension plan assets falls below the actuarial reserve required by law and the shortfall may not be recovered within a certain moratorium period permitted by laws and/or special legislative decree, Sony may be required to make an additional contribution to

15

---

Table of Contents

its plans, which may reduce cash flows. Similarly, if Sony is required to make an additional contribution to a foreign plan to meet any funding requirements in accordance with local laws and regulations in each country, Sony’s cash flows might be adversely affected. If Sony is required to increase cash contributions to its pension plans when actuarial assumptions, such as an expected long-term rate of return of the pension plan assets, are updated for purposes of determining statutory contributions, it may have an adverse impact on Sony’s cash flows.

Further losses in jurisdictions where Sony has established valuation allowances against deferred tax assets, the inability of Sony to fully utilize its deferred tax assets, limitations on the use of its deferred tax assets under local law, exposure to additional tax liabilities or changes in Sony’s tax rates could adversely affect Sony’s operating results and financial condition.

Sony is subject to income taxes in Japan and numerous other jurisdictions, and in the ordinary course of its business there are many situations where the ultimate tax determination can be uncertain, because of the transfer pricing for its intercompany transactions, and because Sony is subject to continuous review by tax authorities of numerous jurisdictions. The calculation of Sony’s tax provision and the carrying value of tax assets, including net operating loss carryforwards and tax credit carryforwards, require significant judgment and the use of estimates, including estimates of future taxable income. As additional evidence becomes available, Sony reassesses these assets to determine if they remain appropriate or whether a reduction by a valuation allowance is appropriate. As of March 31, 2020, total established valuation allowances were 608.2 billion yen. An increase in a valuation allowance may have an adverse impact on Sony’s operating results and financial condition.

Deferred tax assets are evaluated on a jurisdiction by jurisdiction basis. As of March 31, 2020, Sony and/or its subsidiaries had valuation allowances principally in Japan and the U.S. Additionally, deferred tax assets could expire unused or otherwise not be realizable for a variety of reasons including the lack of sufficient taxable income in the appropriate jurisdiction. Sony’s operating results and financial condition could be adversely affected when the deferred tax assets expire unused.

In some jurisdictions, the use of net operating loss carryforwards or tax credits to reduce taxable income in a subsequent period is limited to a fixed percentage of taxable income or may only be used to offset taxes on income from certain sources. Thus, it is possible that even with significant net operating loss carryforwards or tax credits, Sony could record and pay taxes in a jurisdiction where it has taxable income.

In addition to the above, Sony’s future effective tax rates may be unfavorably affected by changes in both the statutory rates and the mix of earnings in countries with differing statutory rates or by other factors such as changes in tax laws and regulations or their interpretation, including limitations or restrictions on various tax deductions and credits, including deductions for royalties and interest. For example, compliance with the U.S. Tax Cuts and Jobs Act of 2017 (the “U.S. Tax Reform Act”) may require the use of estimates in Sony’s financial statements, and the exercise of significant judgment in accounting for its provisions. As regulations and guidance evolve with respect to the U.S. Tax Reform Act, Sony may make adjustments to amounts that have been previously recorded that may materially affect Sony’s operating results and financial condition.

Sony could incur asset impairment charges for goodwill, intangible assets or other long-lived assets.

Sony has a significant amount of goodwill, intangible assets and other long-lived assets, including production facilities and equipment in its electronics businesses. A decline in financial performance, market capitalization, reduced estimates of future cash flows, changes in global economic conditions or changes in estimates and assumptions used in the impairment analysis, which in many cases requires significant judgment, could result in impairment charges against these assets. Goodwill and indefinite lived intangible assets are tested annually for impairment during the fourth quarter of the fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below the carrying amount. Such an event or change in circumstances would include unfavorable variances from or adjustments to established business plans, significant changes in forecasted results or volatility inherent to external markets and industries. The increased levels of global competition and the faster pace of technological change to which Sony is exposed can result in greater volatility of these estimates, assumptions and judgments, and increase the likelihood of impairment charges. In addition, the recoverability of the carrying value of long-lived assets held and used and long-lived assets to be disposed of is reviewed whenever events or changes in circumstances, including the types of events or changes described above with respect to goodwill and intangible assets, indicate that the carrying value of the assets or asset groups may not be recoverable. If the carrying value of the asset or asset group is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the asset or asset group exceeds its fair value. For example, Sony recorded an impairment loss of 31.3 billion yen, 19.2 billion yen and 12.7 billion yen for the fiscal years ended March 31, 2018, 2019 and 2020, respectively,

against long-lived assets in the EP&S segment, related to the smartphone business asset group, as well as an impairment loss of 12.9 billion yen for the fiscal year ended March 31, 2019, against long-lived assets and goodwill in the All Other segment, related to the storage media business asset group. Any such charge may adversely affect Sony’s operating results and financial condition.

Holders of American Depositary Shares have fewer rights than shareholders and may not be able to enforce judgments based on U.S. securities laws.

The rights of shareholders under Japanese law to take actions, including voting their shares, receiving dividends and distributions, bringing derivative actions, examining Sony’s accounting books and records, and exercising appraisal rights, are available only to shareholders of record. Because the depositary, through its custodian agents, is the record holder of the shares underlying the American Depositary Shares (“ADSs”), only the depositary can exercise those rights in connection with the deposited shares. The depositary will make efforts to vote the shares underlying ADSs in accordance with the instructions of ADS holders and will pay the dividends and distributions collected from Sony. However, ADS holders will not be able to bring a derivative action, examine Sony’s accounting books and records, or exercise appraisal rights through the depositary. 

Sony Corporation is incorporated in Japan with limited liability. A majority of Sony’s directors and corporate executive officers are

 non-U.S.

 residents, and a substantial portion of the assets of Sony Corporation and the assets of Sony’s directors and corporate executive officers are located outside the U.S. As a result, it may be more difficult for investors to enforce against Sony Corporation or such persons, judgments obtained in U.S. courts predicated upon civil liability provisions of the federal and state securities laws of the U.S. or similar judgments obtained in other courts outside Japan. There is doubt as to the enforceability in Japanese courts, in original actions or in actions for enforcement of judgments of U.S. courts, of civil liabilities predicated solely upon the federal and state securities laws of the U.S.

Prior notification under the Foreign Exchange and Foreign Trade Act of Japan may be required in the case of an acquisition by a foreign investor of a certain portion of our shares.

Because Sony is engaged in certain businesses designated by the Foreign Exchange and Foreign Trade Act of Japan and its related cabinet orders and ministerial ordinances (collectively, the “Foreign Exchange Regulations”), if a foreign investor intends to consummate an acquisition of shares of common stock of Sony Corporation and that acquisition constitutes an “inward direct investment” under the Foreign Exchange Regulations, the foreign investor, subject to certain exemptions, must file a prior notification of such inward direct investment with the Minister of Finance and any other competent Ministers. An amendment to the Foreign Exchange Regulations came into effect on May 8, 2020 (the “Amendment”) and the Amendment was fully implemented on June 7, 2020. Under the Amendment, an “inward direct investment” includes an acquisition by a foreign investor of shares of common stock of Sony Corporation, the consummation of which results in such foreign investor, in combination with any existing shareholding, directly or indirectly holding 1% or more (lowered from 10% by the Amendment) of the total number of issued shares of common stock or the total number of voting rights of Sony Corporation. The Amendment also introduced certain exemptions from the prior notification requirements.

If such prior notification is filed, the proposed acquisition may not be consummated until the prescribed screening period expires. In some cases, the Ministers may extend the screening period, and may recommend or order any modification or the abandonment of such acquisition. In addition, if certain conditions – including those prescribed in light of national security of Japan – under the Foreign Exchange Regulations are met, the Ministers may order the foreign investor to divest the shares acquired or take other measures. Consequently, any proposed acquisition by a foreign investor of shares of common stock of Sony Corporation that constitutes an “inward direct investment” may not be consummated in an expected time frame in accordance with an intended plan, or at all.

Additionally, after the implementation of the Amendment, if a foreign investor directly or indirectly holds 1% or more of the total voting rights of Sony Corporation and, at a general meeting of shareholders, consents to certain proposals having a material influence on the management of Sony Corporation such as the (i) election of such foreign investor or any of its related persons (as defined in the Foreign Exchange Regulations) as a director of Sony Corporation or (ii) transfer or discontinuation of its business, such consent, subject to certain exemptions, also constitutes an “inward direct investment” requiring prior notification. If such prior notification is filed, such consent cannot be given until the prescribed screening period expires. As a result, such foreign investors may have difficulties giving such consent in accordance with an intended plan, or at all.

Sources of Supply

Sony procures raw materials, parts and components used in the production of its products on a global basis on the most favorable terms that it can achieve. These items are purchased from various suppliers around the world. Sony has a general policy of maintaining multiple suppliers for important parts and components and, in the fiscal year ended March 31, 2020, Sony continued to optimize the number of its suppliers to achieve efficiencies and to minimize procurement risk when possible.

When raw materials, parts and components become scarce, the cost of production rises. For example, LCD panels, memory devices and other discrete components, which are used in multiple applications, can influence Sony’s performance when the cost of such parts and components fluctuates substantially. Regarding raw materials, the market price of copper may fluctuate and impact the cost of the parts and components that utilize copper, such as printed circuit boards and power cables. The price of resin and sheet steel, which are widely used in mechanical parts and components, may also fluctuate and impact the cost of those parts and components.

After-Sales Service

Sony provides repair and servicing functions in the areas where its G&NS, EP&S and I&SS products are sold. Sony provides these services through its own online support network, call centers, service centers, factories, authorized independent service centers, authorized servicing dealers and subsidiaries.

In line with industry practices of these businesses, almost all of Sony’s

consumer-use

products that are sold in Japan carry a warranty, generally for a period of one year from the date of purchase, covering repairs, free of charge, in the case of a malfunction in the course of ordinary use of the product. Warranties outside of Japan generally provide coverage for various periods of time depending on the product and the area in which it is marketed. In the case of broadcast- and

professional-use

products, Sony maintains support contracts with customers in addition to warranties.

To further help ensure customer satisfaction, Sony maintains customer information centers in its principal markets and web support information for all markets.

Patents and Licenses

Sony has a number of Japanese and foreign patents relating to its products. Sony is licensed to use a number of patents owned by others, covering a wide range of products. Certain of these licenses are important to Sony’s business. Sony products that employ DVD player functionality, including PlayStation

®

4 (“PS4

™

”) hardware, are substantially dependent upon patents that relate to technologies specified in the DVD specifications and are licensed from Dolby Laboratories Licensing Corporation. Sony products that employ

Blu-ray

Disc

™

player functionality and DVD player functionality, including PS4 hardware, are substantially dependent upon patents that relate to technologies specified in the

Blu-ray

Disc

™

specifications and are licensed by MPEG LA LLC and

One-Blue,

LLC, in addition to the patents that relate to technologies specified in the DVD specifications, as described above. Sony considers its overall license position beneficial to its operations.

Competition

In each of its principal product lines and services, Sony encounters intense competition throughout the world. Sony believes, however, that in the aggregate it competes successfully and has a major position in all of the principal product lines and services in which it is engaged, although the strength of its position varies with products and markets. Refer to “Risk Factors” in “Item 3.

Key Information

.”

G&NS, EP&S, I&SS and All Other

Sony believes that its product planning and product design expertise, the high quality of its products, its record of innovative product introductions and product improvements, the user experience it provides and the ecosystem that supports such an experience, its price competitiveness derived from reductions in manufacturing and indirect costs, and its extensive marketing and servicing efforts are important factors in maintaining its competitive position. Continuing to provide high-value added products, services and experiences is a key factor by which Sony aims to differentiate itself in these highly competitive markets. Sony believes that the success of the G&NS businesses is determined by the availability of attractive software titles and related content, downloadable content, network services and peripherals. In the I&SS segment, Sony puts significant effort into keeping Sony’s strong competitive position by investing in R&D and production capacity, while also trying to avoid overinvesting and increasing fixed costs by carefully monitoring customer demand, market trends and demand for

end-user

products.

Music

Success in the music industry is dependent to a large extent upon the artistic and creative abilities of artists, producers and employees and is subject to the vagaries of public taste. The Music segment’s future competitive position depends on its continuing ability to attract and develop artists and products that can achieve a high degree of public acceptance as well as offer efficient services. In addition, Sony believes that the success of the Music segment’s animation products and game applications business, Aniplex, is largely dependent on the creative talent of game producers and developers, and is also subject to the vagaries of public taste.

Pictures

SPE faces intense competition from all forms of entertainment and other leisure activities to attract the attention of audiences worldwide. SPE competes with other motion picture studios and production companies to obtain story rights and talent, including writers, actors, directors and producers, which are essential to the success of SPE’s products. SPE competes with other companies, in particular technology companies, who are expanding into the production or distribution of film and television programing. In motion picture production and distribution, SPE faces competition to obtain exhibition and distribution outlets and optimal release dates for its products. In addition, SPE faces competition to acquire motion pictures and television programming from third

26

Table of Contents

parties. In television production and distribution, competition arises from the increasing fragmentation of audiences among broadcast and cable networks, DBS providers, digital platforms and other outlets both within and outside of the U.S. Furthermore, broadcast networks in the U.S., or their affiliated production companies, continue to produce their own shows internally, and major streaming services in and outside the United States are producing more content themselves or acquiring content from affiliated production companies. This competitive environment may result in fewer opportunities to produce shows for such networks and services, and may contribute to shorter lifespans for ordered shows that do not immediately achieve favorable ratings. SPE’s worldwide television networks compete for viewers with broadcast and cable networks, DBS providers, digital platforms and other forms of entertainment. The growth in the number of networks around the world has increased the competition for advertising and subscription revenues, acquisition of programming, and distribution of SPE’s television networks by cable, DBS providers, digital platforms and other distribution systems.

Financial Services

In the Financial Services segment, Sony faces strong competition in the financial services markets in Japan. In recent years, the regulatory barriers between the life insurance and

non-life

insurance industries as well as among the insurance, banking and securities industries have been relaxed, resulting in new competitive pressures.

Sony Life competes not only with traditional insurance companies in Japan but also with other companies including online insurance companies, foreign-owned life insurance companies and a number of Japanese cooperative associations.

Sony Assurance competes against insurers that sell their policies through sales agents as well as insurers that, like Sony Assurance, primarily sell their policies through direct marketing via the internet and via telephone. Competition in Japan’s

non-life

insurance industry has intensified in recent years, in part due to a number of new market entrants, including foreign-owned insurers.

Some of the competitors in the life insurance and

non-life

insurance businesses have advantages over Sony including:

•

greater financial resources and financial strength ratings;

•

greater brand awareness;

•

more extensive marketing and sales networks, including through tie-ups with other types of financial institutions;

•

more competitive pricing;

•

larger customer bases; and

•

a wider range of products and services.

Sony Bank has focused on providing retail asset management and mortgage services for individuals, and faces significant competition in Japan’s retail financial services market. Sony Bank competes with traditional banking institutions, regional banks, trust banks,

non-bank

companies, and newer financial groups providing online full-services of bank and brokerage in Japan.

In the Financial Services segment, it is important to maintain a strong and healthy financial foundation for the business as well as to meet diversifying customer needs. Sony Life and Sony Assurance have maintained a high solvency margin ratio, relative to the Japanese domestic minimum solvency margin ratio requirements. Sony Bank has maintained a sufficient capital adequacy ratio relative to the Japanese domestic criteria.

Government Regulations

Sony’s business activities are subject to various governmental regulations in different countries in which it operates, including regulations relating to: various business/investment approvals; trade affairs, including customs, import and export control; competition and antitrust; anti-bribery; advertising and promotion; intellectual property; broadcasting, consumer and business taxation; foreign exchange controls; economic sanctions; personal information protection; product safety; labor; human rights; conflict; occupational health and safety; environmental; and recycling requirements.

Table of Contents

In Japan, Sony’s insurance businesses are subject to the Insurance Business Act and approvals and oversight from the Financial Services Agency (“FSA”). The primary purpose of the Insurance Business Act and related regulations is to protect policyholders, not shareholders. The Insurance Business Act specifies the types of businesses insurance companies may engage in, imposes limits on the types and amounts of investments that can be made and requires insurance companies to maintain specified reserves and a minimum solvency margin ratio. In particular, life insurance companies must maintain a premium reserve (for the portion of their portfolio other than unearned premiums), an unearned premium reserve, a reserve for refunds with respect to certain insurance contracts of life insurance companies specified in the Insurance Business Act’s regulations, and a contingency reserve in amounts no lower than the amount of the “standard policy reserve” as set forth by the regulatory guidelines. The FSA maintains a solvency standard which is used by Japanese regulators to monitor the financial strength of insurance companies.

Non-life

insurance companies are also required to provide a policy reserve. Sony Bank is also subject to regulation by the FSA under the Banking Act of Japan, including the requirement that it maintain a minimum capital adequacy ratio in accordance with capital adequacy guidelines adopted by the FSA based on the Basel III agreement. The FSA has broad regulatory powers over insurance and banking businesses in Japan, including the authority to grant or revoke operating licenses and to request information and conduct onsite inspections of books and records. Sony’s subsidiaries in the Financial Services segment are subject to the Japanese Insurance Business Act and Banking Act that require insurance and business companies to maintain their financial credibility and to secure protection for policyholders and depositors in view of the public importance of insurance and banking services. As such, lending and borrowing between subsidiaries in the Financial Service segment and the other companies within Sony Group is strictly limited.

In addition, Sony’s telecommunication businesses in Japan are subject to approvals and oversight from the Ministry of Internal Affairs and Communications, under the Telecommunications Business Act and other regulations related to the internet businesses and communication methods in Japan.

Social Responsibility Regulations Such as Environmental and Human Rights Regulations

Sony monitors, evaluates, and complies with new environmental requirements that may affect its operations. For example, in Europe, Sony is required to comply with a number of environmental regulations enacted by the EU such as the Restriction of Hazardous Substances (“RoHS”) Directive, the Waste Electrical and Electronic Equipment (“WEEE”) Directive and the Registration, Evaluation, Authorization and Restriction of Chemicals (“REACH”) regulation. Similar regulations are being formulated in other areas of the world, including South American, Southeast Asian and Middle Eastern countries.

Sony has taken steps to address new regulations or governmental policies related to climate change including carbon disclosure, greenhouse gas emission reduction, carbon taxes and energy efficiency for products in the G&NS, EP&S and I&SS segments. For example, Sony has established an internal management system in response to the EU directive on energy-related products and their energy efficiency (“ErP”).

Sony also monitors and evaluates newly adopted laws and regulations that may affect its operations applicable to purchasing activities including the procurement of raw materials, with respect to environmental, occupational health and safety, human rights, labor and armed conflict issues, and complies as appropriate.

Disclosure pursuant to Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012

Section 219 of the Iran Threat Reduction and Syria Human Rights Act of 2012 added Section 13(r) to the Securities Exchange Act of 1934 (the “Exchange Act”), as amended. Section 13(r) requires an issuer to disclose in its annual or quarterly reports, as applicable, whether it or any of its affiliates knowingly engaged in certain activities, transactions or dealings relating to Iran or with designated natural persons or entities sanctioned under programs relating to terrorism or the proliferation of weapons of mass destruction. Disclosure is required even where the activities, transactions or dealings are conducted outside the U.S. by

non-U.S.

affiliates in compliance with applicable law, and whether or not the activities are sanctionable under U.S. law.

Sony is aware that certain transactions during the fiscal year ended March 31, 2020, as described below, may be disclosable pursuant to Section 13(r) of the Exchange Act.

The information below is to the best of Sony’s knowledge, and in particular Sony may not be aware of all potentially reportable sales by third-party-owned dealers and distributors.

Sony’s representative office in Tehran, Iran, which was established in 1992, has been closed and has been under liquidation processes since before the beginning of the fiscal year ended March 31, 2014. In

Table of Contents

the course of liquidation, Sony engages in certain incidental transactions (for example, permits, taxes, and similar matters incidental to the wind-down of the office in Iran) with Iranian government-owned entities. No material revenues or profits are associated with these transactions with the Iranian government-owned entities.

Sony is not aware of any other activity, transaction or dealing by Sony Corporation or any of its affiliates during the fiscal year ended March 31, 2020 that is disclosable in this report under Section 13(r) of the Exchange Act. As of the date of this report, Sony does not anticipate that any activity, transaction or dealing that may be disclosable will be conducted during the fiscal year ending March 31, 2021, except as described above in connection with the wind-down of its representative office in Iran. Nevertheless, Sony has continued to monitor developments in this area, especially in the light of the United States’ decision that was implemented in its entirety on November 5, 2018 to cease its participation in the Joint Comprehensive Plan of Action of July 14, 2015, among the United States, the United Kingdom, China, France, Russia, Germany, the European Union and Iran and

re-impose

certain secondary sanctions (i.e., laws and regulations that threaten to impose U.S. economic sanctions on

non-U.S.

companies engaging in specified transactions with Iran outside U.S. jurisdiction). As sanctions against Iran continue to evolve, Sony will continue to assess whether and to what extent such sanctions may affect Sony’s business activities, which Sony intends to conduct in accordance with applicable laws and regulations.

Sony believes, and maintains policies and procedures designed to ensure that, its transactions with Iran and elsewhere have been conducted in accordance with applicable economic sanctions laws and regulations and do not involve transactions likely to result in the imposition of sanctions or other penalties on Sony. However, there can be no assurance that Sony’s policies and procedures will be effective, and if the relevant authorities were to impose penalties or sanctions against Sony, the impact of such sanctions could be material.

Operating Performance

The following discussion covers the fiscal years ended March 31, 2019 and 2020. For the discussion covering the fiscal year ended March 31, 2018, please refer to “Item 5.A.” of Sony’s Form

20-F

for the fiscal year ended March 31, 2019 filed with the SEC on June 18, 2019.

		Fiscal year ended March 31
		2019				2020

Sales

For the fiscal year ended March 31, 2020, sales and operating revenue (“Sales”) decreased 405.8 billion yen compared to the fiscal year ended March 31, 2019

(“year-on-year”)

to 8 trillion 259.9 billion yen. This was mainly due to significant decreases in sales in the Electronics Products & Solutions (“EP&S”) and the Game & Network Services (“G&NS”) segments, partially offset primarily by a significant increase in sales in the Imaging & Sensing Solutions (“I&SS”) segment. Sales in the current fiscal year also included 7.9 billion yen in patent royalty revenue resulting from the signing of a licensing agreement, recorded within Corporate and elimination. A further breakdown of sales figures is presented under “Operating Performance by Business Segment” below.

Table of Contents

Cost of Sales, Selling, General and Administrative Expenses and Other Operating (Income) Expense, net

“Sales” in the analysis of the ratio of “cost of sales” to sales, the ratio of “R&D costs” to sales, and the ratio of “selling, general and administrative expenses” (“SGA expenses”) to sales refers only to the net sales and other operating revenue portions of consolidated sales (which excludes financial services revenue). This is because financial services expenses are recorded separately from cost of sales and SGA expenses in the consolidated financial statements. The calculations of all ratios below that pertain to reportable segments include intersegment transactions.

For the fiscal year ended March 31, 2020, cost of sales decreased 397.6 billion yen

year-on-year

to 4 trillion 753.2 billion yen. The ratio of cost of sales to sales improved

year-on-year

from 69.7% to 68.3%.

R&D costs (all R&D costs are included within cost of sales) increased 18.1 billion yen

year-on-year

to 499.3 billion yen. The ratio of R&D costs to sales was 7.2% compared to 6.5% in the fiscal year ended March 31, 2019. For further details, refer to

“Research and Development

” in Item 5.C.

SGA expenses decreased 74.2 billion yen

year-on-year

to 1 trillion 502.6 billion yen. The ratio of SGA expenses to sales deteriorated

year-on-year

from 21.3% to 21.6%.

Other operating income, net, decreased 68.0 billion yen

year-on-year

to 3.6 billion yen. This significant deterioration was mainly due to the following factors that occurred in the fiscal year ended March 31, 2020 and the absence of the following factors that occurred in the fiscal year ended March 31, 2019. Refer to Note 21 of the consolidated financial statements.

Factors that occurred in the fiscal year ended March 31, 2020

•

Remeasurement and realized gains resulting from the public listing and sale of a portion of shares of SRE Holdings Corporation: 17.3 billion yen (All Other)

•

Realized and remeasurement gains resulting from the transfer of a portion of shares of NSF Engagement Corporation: 6.3 billion yen (Corporate and elimination)

Factors that occurred in the fiscal year ended March 31, 2019

•

Remeasurement gain resulting from Sony’s acquisition of the remaining approximately 60% equity interest in DH Publishing, L.P. (“EMI”), which owned and managed EMI Music Publishing: 116.9 billion yen (Music segment)

•

An impairment charge against long-lived assets of the smartphone business: 19.2 billion yen (EP&S segment)

•

An impairment charge against long-lived assets and goodwill of the storage media business: 12.9 billion yen (All Other)

Equity in Net Income (Loss) of Affiliated Companies

For the fiscal year ended March 31, 2020, equity in net income (loss) of affiliated companies was income of 9.6 billion yen, compared to a loss of 3.0 billion yen in the fiscal year ended March 31, 2019. This improvement was mainly due to the absence of the 11.6 billion yen recording of equity in net loss for EMI, mainly due to expenses relating to warrants and management equity plans in connection with Sony’s acquisition of the remaining approximately 60% equity interest in EMI, recorded in the Music segment in the fiscal year ended March 31, 2019.

Operating Income

For the fiscal year ended March 31, 2020, operating income decreased 48.8 billion yen

year-on-year

to 845.5 billion yen. This decrease was primarily due to significant decreases in operating income in the Music and G&NS segments, partially offset by significant increases in operating income mainly in the I&SS segment and All Other. Operating income for the current fiscal year as well as the previous fiscal year included the above-mentioned factors being recorded as other operating (income) expense, net.

Other Income and Expenses

For the fiscal year ended March 31, 2020, other income decreased by 122.8 billion yen

year-on-year,

to 21.9 billion yen, while other expenses increased by 40.6 billion yen

year-on-year,

to 68.0 billion yen. The net

32

---

Table of Contents

amount of other income and other expenses was an expense of 46.0 billion yen, a deterioration of 163.4 billion yen

year-on-year

mainly due to the absence of the 117.8 billion yen realized and unrealized gains resulting from the public listing and sale of certain shares of Spotify Technology S.A. (“Spotify”) recorded in the fiscal year ended March 31, 2019, as well as the recording of a loss on equity securities, net, in the fiscal year ended March 31, 2020 and a

year-on-year

increase in net foreign exchange losses.

The foreign exchange loss, net, increased by 15.5 billion yen

year-on-year,

to 26.8 billion yen.

Interest and dividends in other income of 19.3 billion yen were recorded in the fiscal year ended March 31, 2020, an decrease of 2.3 billion yen

year-on-year.

Interest recorded in other expenses totaled 11.1 billion yen, a decrease of 1.3 billion yen

year-on-year.

Income before Income Taxes

For the fiscal year ended March 31, 2020, income before income taxes decreased 212.2 billion yen

year-on-year

to 799.5 billion yen.

Income Taxes

During the fiscal year ended March 31, 2020, Sony recorded 177.2 billion yen of income tax expense, resulting in an effective tax rate of 22.2%, which was higher than the effective tax rate of 4.5% in the fiscal year ended March 31, 2019. This higher effective tax rate in the fiscal year ended March 31, 2020 was mainly due to the previous fiscal year’s reversal of 154.2 billion yen of valuation allowances against a significant portion of the deferred tax assets in the U.S. consolidated tax group and not recording income tax expense on the remeasurement gain for the equity interest in EMI. Refer to Note 22 of the consolidated financial statements.

Net Income Attributable to Noncontrolling Interests

For the fiscal year ended March 31, 2020, net income attributable to noncontrolling interests of 40.1 billion yen was recorded, a decrease of 10.2 billion yen

year-on-year.

Net Income Attributable to Sony Corporation’s Stockholders

For the fiscal year ended March 31, 2020, net income attributable to Sony Corporation’s stockholders, which excludes net income attributable to noncontrolling interests, decreased 334.1 billion yen

For the fiscal year ended March 31, 2020, sales decreased 333.3 billion yen

year-on-year

to 1 trillion 977.6 billion yen. This significant decrease was primarily due to a decrease in PlayStation

®

4 (“PS4

™

”) hardware sales and game software sales, as well as the impact of foreign exchange rates, partially offset by an increase in sales for PlayStation

®

Plus (“PS Plus”).

Operating income decreased 72.7 billion yen

year-on-year

to 238.4 billion yen. This significant decrease was primarily due to the impact of the above-mentioned decrease in game software sales and the negative impact of foreign exchange rates, partially offset by the above-mentioned increase in sales for PS Plus and cost reductions.

Despite a decline in momentum for

free-to-play

games which are monetized via microtransactions rather than

up-front

purchases, the operating performance of the G&NS segment for the fiscal year ended March 31, 2020 reflected the continued demand for hardware, software and network services, and continuous market interest surrounding cloud-based game streaming services. In this environment, Sony continued to focus on delivering immersive experiences to PlayStation

®

users by expanding its network services business in a variety of ways, including through PS Plus and Sony’s proprietary game streaming services, Remote Play and PlayStation

™

Now (“PS Now”). In addition, Sony completed the acquisition of Insomniac Games Inc. as part of its strategy to bolster its first-party software lineup in the fiscal year ended March 31, 2020. In the fiscal year ending March 31, 2021, Sony intends to continue these objectives while also focusing on the launch of PlayStation

®

5 (“PS5

™

”).

Current View Regarding the Impact on the Business from the Spread of the Coronavirus Disease 2019

(“COVID-19”)

Although there has been a slight impact on production of PS4 hardware due to issues in the component supply chain, demand in the short-term is being addressed with current inventory and sales are trending well. Sales of game software that is downloaded from the network, as well as PS Plus and PS Now subscriber numbers have significantly increased. Regarding the launch of PS5, although factors such as employees working from home and restrictions on international travel have presented some challenges in regards to part of the testing process and the qualification of production lines, development is progressing with the launch of the console scheduled for the 2020 holiday season. At this point in time no major problems have arisen in the game software development pipeline for Sony’s own first-party studios or its partners’ studios.

On November 14, 2018, Sony acquired the entirety of the approximately 60% equity interest held by the investor consortium led by Mubadala Investment Company in EMI, resulting in EMI becoming a wholly-owned subsidiary of Sony. Financial results of EMI included in the Music segment for the fiscal year ended March 31, 2019 include equity earnings (loss) from April 1 through November 13, 2018 and sales and operating income (loss) from November 14, 2018 through March 31, 2019. Sales and operating income (loss) for the Music segment in the fiscal year ended March 31, 2020 include the financial results of EMI from April 1, 2019 onward.

The Music segment results include the

yen-translated

results of Sony Music Entertainment (“SME”), Sony/ATV Music Publishing (“Sony/ATV”) and EMI, all U.S.-based operations which aggregate the results of their worldwide subsidiaries on a U.S. dollar basis, and the results of Sony Music Entertainment (Japan) Inc., a Japan-based music company which aggregates its results in yen.

For the fiscal year ended March 31, 2020, sales increased 42.4 billion yen

year-on-year

to 849.9 billion yen. This increase in sales was primarily due to higher sales for Music Publishing resulting from the consolidation of EMI, as well as higher sales for Recorded Music primarily due to an increase in streaming revenues, partially offset by lower Visual Media and Platform sales primarily due to lower sales for

Fate/Grand Order

, a mobile game application.

Operating income decreased 90.1 billion yen

year-on-year

to 142.3 billion yen. This significant decrease in operating income was primarily due to the absence of the recording of a 116.9 billion yen remeasurement gain resulting from the consolidation of EMI in the previous fiscal year, partially offset by the absence of the 11.6 billion yen recording of equity in net loss resulting from Sony’s acquisition of the remaining approximately 60% equity interest in EMI in the previous fiscal year, as well as the impact of the above-mentioned increase in sales.

The operating performance of the Music segment for the fiscal year ended March 31, 2020 reflected continued growth in the market for recorded music despite decreases in physical and digital download revenues, mainly due to the expansion of digital streaming. In this environment, Sony has pursued initiatives to increase streaming, performance, and other licensing revenues through continued investment in new recorded music and music publishing rights. In the fiscal year ending March 31, 2021, Sony intends to continue these initiatives while also continuing to develop and promote mobile game applications based on animation titles.

Current View Regarding the Impact on the Business from the Spread of

COVID-19

Around the world, but especially in the U.S., the release of new music is being delayed primarily due to some artists being unable to record songs and music videos. The impact on profitability from the delays in new music is limited at this time in the U.S. and other countries where the proportion of music that is streamed is high. However, in countries like Japan and Germany where the proportion of music that is streamed is relatively low, CDs and other packaged media sales are decreasing due to restrictions on going outside. Ticket, merchandising and video revenues are decreasing, as concerts and other events are being postponed and cancelled in Japan and other areas. Due to a global reduction in advertising spending, revenue from advertising-supported streaming services and revenue from the licensing of music in TV commercials is decreasing. Additionally, delays in the production of motion pictures and TV shows are causing a decline in music licensing revenue.

The results presented in Pictures are a

yen-translation

of the results of Sony Pictures Entertainment Inc. (“SPE”), a U.S.-based operation that aggregates the results of its worldwide subsidiaries on a U.S. dollar basis. Management analyzes the results of SPE in U.S. dollars, so discussion of certain portions of its results is specified as being on “a U.S. dollar basis.”

For the fiscal year ended March 31, 2020, sales increased 25.0 billion yen (3%)

year-on-year

(a 5% increase on a U.S. dollar basis) to 1 trillion 11.9 billion yen. The increase in sales on a U.S. dollar basis was primarily due to higher worldwide theatrical revenues, as the current fiscal year benefitted from the strong performances of

Spider-Man: Far From Home

,

Jumanji: The Next Level

and

Bad Boys for Life

and higher licensing revenues for Television Productions. These increases in sales were partially offset by a decrease in sales for Media Networks primarily due to the impact of the channel portfolio review that was undertaken in the previous fiscal year.

Operating income increased 13.6 billion yen

year-on-year

to 68.2 billion yen. This significant increase in operating income was primarily due to the benefit of the above-mentioned channel portfolio review and higher profit margins on Motion Pictures catalog titles. These increases were partially offset by lower profitability in Television Productions due to an increase in development expenses as well as higher costs as a result of an increase in the number of new programs produced for U.S. broadcast and cable networks. Operating income was also impacted by an increase in charges related to the channel portfolio review which totaled 17.0 billion yen in the current fiscal year as compared to 12.8 billion yen in the previous fiscal year.

The operating performance of the Pictures segment for the fiscal year ended March 31, 2020 reflected a continued shift in the market to a

non-linear,

on-demand

digital business model in which media distributors increasingly seek to own more of the content they broadcast. In this environment, Sony has worked to enhance the global appeal of its content and enhance its developed and acquired intellectual property, while also striving to build and maintain strong relationships with top content creators and major networks around the world. Pursuant to these strategies, in the fiscal year ended March 31, 2020, Sony acquired AT&T Inc.’s minority stake in Game Show Network, LLC and acquired Silvergate Media Group through which Sony aims to solidify its position as a leader in the U.S. TV game show business and to strengthen its entry into the kids genre, respectively. Additionally, in the fiscal year ended March 31, 2020, Sony carried out a further review of the channel portfolio within Media Networks to streamline and strengthen the business. In the fiscal year ending March 31, 2021, Sony intends to continue initiatives to strengthen its content while maintaining a strong relationship with the creative community.

Current View Regarding the Impact on the Business from the Spread of

COVID-19

Although some movie theaters are reopening, a large number are still closed or must limit the number of patrons, leading to box office revenue around the world being impacted. For this reason, Sony generally has not been able to release its already completed films in theaters. Due to restrictions on peoples’ movement, the production schedules of new motion pictures and television shows by Sony are significantly delayed around the world, especially in the U.S. As a result, in Motion Pictures, theatrical revenues and revenues generated after theatrical release, including home entertainment and television licensing sales, are expected to decrease. On the other hand, digital rental and sell-through revenues for films which Sony released theatrically prior to the spread of

COVID-19

have been strong. In Television Productions, revenues are beginning to be impacted by delays in the delivery of shows to TV networks and digital distribution services. Due to a global reduction in advertising spending, advertising revenue in Media Networks is decreasing significantly, especially in India.

For the fiscal year ended March 31, 2020, sales decreased 329.4 billion yen

year-on-year

to 1 trillion 991.3 billion yen. This significant decrease in sales was primarily due to a decrease in unit sales of smartphones and televisions, as well as the impact of foreign exchange rates.

Operating income increased 10.8 billion yen

year-on-year

to 87.3 billion yen. This increase in operating income was primarily due to reductions in operating costs mainly within Mobile Communications, as well as a decrease in impairment charges against long-lived assets in Mobile Communications, partially offset by the impact of the decrease in overall segment sales and the negative impact of foreign exchange rates.

The operating performance of the EP&S segment for the fiscal year ended March 31, 2020 reflected shrinking markets for televisions, digital cameras and smartphones. In this environment, Sony continued to strengthen its high value-added products in each product area. In addition, Sony carried out initiatives to reduce operational costs in Mobile Communications, with the goal of eliminating the operating loss in Mobile Communications in the fiscal year ending March 31, 2021. Sony intends to continue to strengthen operations in the fiscal year ending March 31, 2021 through these and similar initiatives.

Current View Regarding the Impact on the Business from the Spread of COVID-19

Of the four major manufacturing sites for Sony’s TV business, production was ceased in stages from

mid-March

at the

in-house

factory in Malaysia and at the factories to which Sony outsources in Mexico and Slovakia, pursuant to local government policy. These three factories have returned to partial production, but a portion of supply continues to be insufficient to meet demand. In China and Thailand, the factories owned by Sony that make digital cameras and smartphones are currently operating as usual. Retail sales have decreased significantly due to the closure of retail stores globally, the impact of which is continuing to affect markets like Asia and Latin America. Conversely, in Japan, Europe, North America and China, retail stores are gradually reopening. In addition, sales and profit from digital cameras are being significantly impacted by a substantial slowdown in demand around the world.

I&SS segment operating income			143,874				235,584

For the fiscal year ended March 31, 2020, sales increased 191.2 billion yen

year-on-year

to 1 trillion 70.6 billion yen. This significant increase in sales was primarily due to a significant increase in sales of image sensors for mobile products, resulting from an improvement in product mix as well as an increase in unit sales, partially offset by the impact of foreign exchange rates.

Operating income increased 91.7 billion yen

year-on-year

to 235.6 billion yen. This significant increase in operating income was primarily due to the impact of the above-mentioned increase in sales, partially offset by an increase in depreciation and amortization expenses as well as in research and development expenses and the negative impact of foreign exchange rates.

The operating performance of the I&SS segment for the fiscal year ended March 31, 2020 reflected continued growth in demand for image sensors for mobile products, which is currently the most important market for Sony’s image sensors. This growth was largely due to increased demand from smartphone makers for high value-added products such as multi-sensor cameras and

larger-sized

sensors. In this environment, Sony continued to position image sensors as the primary area of focus for capital expenditure in its

mid-range

plan for capital allocation, pursuant to which Sony continued to invest in production capacity for image sensors and increased its customer base while carefully monitoring demand in the fiscal year ended March 31, 2020. Sony intends to continue these initiatives in the fiscal year ending March 31, 2021.

Current View Regarding the Impact on the Business from the Spread of COVID-19

There has been no major impact on Sony’s manufacturing plants in Japan, which are operating as usual. Sony also understands that factory operations and supply chains at most of its major mobile customers, to whom it sells its image sensors, have been recovering. On the other hand, Sony continues to monitor the extent to which the final outlet for Sony’s products, the smartphone market, may decelerate going forward.

Conditions at Sony’s Manufacturing Plants Resulting from the Spread of

COVID-19

Sony has four manufacturing plants located in China (two in Shanghai, one in Wuxi, Jiangsu, and one in Huizhou, Guangdong). All of these plants were shut down in accordance with local government mandates, from the beginning of the spring holidays on January 24, 2020 until February 9, 2020. From February 10, 2020 all four plants have

re-started

operations in increments. Almost no supply chain issues remain, and operations have returned to the level they were before the spread of the virus. In accordance with a mandate by the local government, Sony shut down both of its

in-house

manufacturing plants in Malaysia (Kuala Lumpur and Penang) from March 18, 2020. On April 16, 2020, Sony received approval from local authorities to

re-start

its Malaysia manufacturing operations, and operations are returning to the level they were before the spread of the virus. Sony shut down its manufacturing plant in the U.K. (Wales) from March 26, 2020 in accordance with a mandate from the local government. From March 31, 2020, Sony partially

re-started

its U.K. manufacturing operations after receiving approval from local authorities under certain conditions. Business has been impacted by factors such as restrictions on the movement of people across national borders, making it difficult for Sony to send engineers to manufacturing hubs such as China and countries in Southeast Asia for the purpose of helping with new product launches or giving instructions on manufacturing.

Financial Services

The Financial Services segment results include Sony Financial Holdings Inc. (“SFH”) and SFH’s consolidated subsidiaries such as Sony Life Insurance Co., Ltd.(“Sony Life”), Sony Assurance Inc.(“Sony Assurance”), and Sony Bank Inc. (“Sony Bank”). The results of Sony Life discussed in the Financial Services segment differ from the results that SFH and Sony Life disclose separately on a Japanese statutory basis.

Table of Contents

For the fiscal year ended March 31, 2020, financial services revenue increased 25.2 billion yen

year-on-year

to 1 trillion 307.7 billion yen. This increase in revenue was primarily due to an increase in insurance premium revenue mainly from single premium insurance, partially offset by a deterioration in net gains and losses on investments in the separate account, both at Sony Life. Revenue at Sony Life increased 28.6 billion yen

year-on-year

to 1 trillion 171.7 billion yen.

Operating income decreased 31.9 billion yen

year-on-year

to 129.6 billion yen, due to decreases in operating income at Sony Life and Sony Bank. Operating income at Sony Life decreased 22.1 billion yen

year-on-year

to 123.5 billion yen, mainly due to an increase in the provision of policy reserves and a deterioration in net gains and losses on investments, primarily driven by a decline in the stock market and lower interest rates. Operating income at Sony Bank decreased due to a deterioration in valuation gains and losses on securities.

The operating performance of the Financial Services segment for the fiscal year ended March 31, 2020 reflected conditions in the Japanese economy and bond market. The Japanese economy remained solid in the first half but declined rapidly in the second half. Bond markets were strongly affected by U.S. monetary policy, and market interest rates declined. In addition, the spread of

COVID-19

from the start of the 2020 calendar year significantly and negatively impacted the economy, and March saw sharp fluctuations in interest rates. Amid these circumstances, SFH strove to become the financial services group most highly trusted by customers in Japan, undertaking a variety of measures to maintain a sound financial base, reinforce and expand product and service offerings in order to deliver high value-added products and high-quality services to each of its customers, and enhance SFH’s internal control system. In the fiscal year ending March 31, 2021, Sony plans to continue to pursue growth in the Financial Services segment by focusing on differentiating itself through high-quality financial products and services.

Current View Regarding the Impact on the Business from the Spread of COVID-19

Pursuant to the announcement of a state of emergency by the Japanese government, all

in-person

sales activity of the Lifeplanner

®

salespeople at Sony Life was suspended from April to May 25, 2020, when the state of emergency was lifted. Although these sales activities have resumed from June 1, 2020, the business was impacted by factors such as a decrease in applications for new insurance policies during the period when sales activities were stopped. It is possible that fluctuations in the financial market could impact the financial results of this segment.

Information on Operations Separating Out the Financial Services Segment

The following schedules show unaudited condensed statements of income for the Financial Services segment and all other segments excluding Financial Services. These presentations are not in accordance with U.S. GAAP, which is used by Sony to prepare its consolidated financial statements. However, because the Financial Services segment is different in nature from Sony’s other segments, Sony believes that a comparative presentation may be useful in understanding and analyzing Sony’s consolidated financial statements. Transactions between the Financial Services segment and Sony without the Financial Services segment, including noncontrolling interests, are included in those respective presentations, then eliminated in the consolidated figures shown below.

to 251.4 billion yen. This significant decrease in sales was primarily due to a decrease in sales in the disc manufacturing business and the storage media business.

Operating income of 16.3 billion yen was recorded, compared to operating loss of 11.1 billion yen in the fiscal year ended March 31, 2019. Despite the impact of the above-mentioned decrease in sales, operating results improved significantly mainly due to the 17.3 billion yen remeasurement and realized gains resulting from the public listing and sale of a portion of shares of SRE Holdings Corporation, as well as the absence of the 12.9 billion yen impairment charge against long-lived assets and goodwill in the storage media business recorded in the fiscal year ended March 31, 2019.

Restructuring

In a highly competitive landscape, Sony has continued to make efforts to optimize the organization and improve the performance of its businesses, and it has undertaken restructuring initiatives including exiting businesses or product categories, reducing headcount, and streamlining its sales and administrative functions. For example, during the fiscal year ended March 31, 2020, Sony implemented various restructuring initiatives mainly within the EP&S segment, primarily aimed at improving the profitability of Mobile Communications. Additionally, Sony implemented restructuring initiatives in other segments, including the continuation of the review of the channel portfolio within Media Networks in the Pictures segment, which began in the previous fiscal year in an effort to streamline the business.

Sony believes the competitive environment will continue to be difficult, and therefore plans to be vigilant with respect to the scale of its businesses and to changes in the environment. Sony will continue to evaluate the cost and profit structure of its businesses and take action to reduce cost where Sony believes appropriate.

The chart below shows the restructuring charges, which include

non-cash

charges related to depreciation associated with restructured assets, recorded in the fiscal years ended March 31, 2019 and 2020. For further details, refer to Note 20 of the consolidated financial statements.

Foreign Exchange Fluctuations and Risk Hedging

During the fiscal year ended March 31, 2020, the average rates of the yen were 108.7 yen against the U.S. dollar and 120.8 yen against the euro, which were 2.2 yen and 7.7 yen higher, respectively, than the fiscal year ended March 31, 2019. For the latest yen exchange rates per U.S. dollar, refer to “Selected Financial Data” in “Item 3.

Key Information.

”

For the fiscal year ended March 31, 2020, consolidated sales decreased 405.8 billion yen (5%)

year-on-year

to 8,259.9 billion yen. On a constant currency basis, sales decreased approximately 3%

year-on-year.

Consolidated operating income decreased 48.8 billion yen

year-on-year

to 845.5 billion yen. The foreign exchange fluctuations had a negative impact on the consolidated operating results mainly in the G&NS, EP&S and I&SS segments.

During the fiscal year ended March 31, 2020, sales for the Music segment increased 5%

year-on-year

to 849.9 billion yen, while sales increased approximately 7%

year-on-year

on a constant currency basis. In the Pictures segment, sales increased 3%

year-on-year

to 1,011.9 billion yen, while sales increased approximately 5% on a U.S. dollar basis. For a detailed analysis of segment performance, refer to the Music and Pictures segments under “

Operating Performance by Business Segment

.” Sony’s Financial Services segment consolidates the

yen-based

results of SFH. As most of the operations in this segment are based in Japan, Sony management analyzes the performance of the Financial Services segment on a yen basis only.

During the fiscal year ended March 31, 2020, Sony estimated that a one yen appreciation against the U.S. dollar would have decreased sales in the G&NS, EP&S and I&SS segments by approximately 22.8 billion yen, with almost no impact on operating income. A one yen appreciation against the euro was estimated to decrease sales in these segments by approximately 8.8 billion yen, with a corresponding decrease in operating income of approximately 5.0 billion yen. For more details, refer to “Risk Factors” in “Item 3.

Key Information

.”

Sony’s consolidated operating results are subject to foreign currency rate fluctuations primarily due to different currency composition of revenue and costs. In the G&NS segment, a significant proportion of costs is incurred in U.S. dollars but sales are recorded in Japanese yen, U.S. dollars or euros. As a result, the yen appreciation against the U.S. dollar has a positive impact on operating income while the yen appreciation against the euro has a negative impact. In the EP&S segment, yen appreciation against the U.S. dollar has a positive impact on operating income, mainly due to a high proportion of manufacturing and other costs for certain key products being incurred in U.S. dollars. Meanwhile, a large portion of sales for certain key products is in emerging markets, resulting in yen appreciation against the currencies of emerging markets having a negative impact on operating profit in the EP&S segment. In the I&SS segment, a significant proportion of sales contracts are denominated in U.S. dollars, but manufacturing operations are located in Japan, and, therefore, yen appreciation against the U.S. dollar has a significantly negative impact on operating income.

In order to reduce the risk caused by foreign exchange rate fluctuations, Sony employs derivatives, including foreign exchange forward contracts and foreign currency option contracts, in accordance with a consistent risk management strategy. Such derivatives are used primarily to mitigate the effect of foreign currency exchange rate fluctuations on cash flows generated or anticipated by Sony’s transactions and accounts receivable and payable denominated in foreign currencies.

Sony Global Treasury Services Plc (“SGTS”) in the U.K. provides integrated treasury services for Sony Corporation, its subsidiaries, and affiliated companies. Sony’s policy is that Sony Corporation and all subsidiaries with foreign exchange exposures should enter into commitments with SGTS to hedge their exposures. Sony Corporation and most of its subsidiaries utilize SGTS for this purpose. Sony’s policy of concentrating its foreign exchange exposures means that SGTS and Sony Corporation hedge most of the net foreign exchange exposure within the Sony group. Sony has a policy on the use of derivatives that, in principle, SGTS should centrally deal with and manage derivatives with financial institutions for risk management purposes. SGTS enters into foreign exchange transactions with creditworthy third-party financial institutions. Most of these transactions are entered into against projected exposures before the actual export and import transactions take place. In general, SGTS hedges the projected exposures for a period of one to three months before the actual transactions take place. Sony enters into foreign exchange transactions with financial institutions primarily for hedging purposes. Sony does not use these derivative financial instruments for trading or speculative purposes except for certain derivatives in the Financial Services segment. In the Financial Services segment, Sony uses derivatives primarily for asset liability management.

To minimize the effects of foreign exchange fluctuations on its operating results, particularly in the G&NS, EP&S and I&SS segments, Sony seeks, when appropriate, to localize material and parts procurement, design and manufacturing operations in areas outside of Japan.

Changes in the fair value of derivatives designated as cash flow hedges are initially recorded in accumulated other comprehensive income and reclassified into earnings when the hedged transaction affects earnings. Foreign exchange forward contracts, foreign currency option contracts and other derivatives that do not qualify as hedges are

marked-to-market

with changes in value recognized in other income and expenses. The notional amount of all the foreign exchange derivative contracts as of March 31, 2019 and 2020 was 1,842.8 billion yen and 1,697.4 billion yen, respectively. The net fair value of all the foreign exchange derivative contracts as of March 31, 2019 and 2020 was a liability of 3.6 billion yen and an asset of 5.2 billion yen, respectively. Refer to Note 14 of the consolidated financial statements.

* Note: In this section, the impact of foreign exchange rate fluctuations on sales is calculated by applying the change in the yen’s periodic weighted average exchange rates for the previous fiscal year from the current fiscal year to the major transactional currencies in which the sales are denominated. The impact of foreign exchange rate fluctuations on operating income (loss) is calculated by subtracting from the impact on sales the impact on cost of sales and selling, general and administrative expenses calculated by applying the same major transactional currencies calculation process to cost of sales and selling, general and administrative expenses as for the impact on sales. The I&SS segment enters into its own foreign exchange hedging transactions, and the impact of those transactions is included in the impact of foreign exchange rate fluctuations on operating income (loss) for that segment. Additionally, the impact of foreign exchange hedging transactions entered into by Mobile Communications during the previous fiscal year is included in the impact of foreign exchange rate fluctuations on operating income (loss) for the EP&S segment. The descriptions of sales on a constant currency basis reflect sales obtained by applying the yen’s monthly average exchange rates from the fiscal year ended March 31, 2019 to local currency-denominated monthly sales in the fiscal year ended March 31, 2020. For SME, Sony/ATV and EMI in the Music segment, and in the Pictures segment, the constant currency amounts are calculated by applying the monthly average U.S. dollar / yen exchange rates after aggregation on a U.S. dollar basis. This information is not a substitute for Sony’s consolidated financial statements measured in accordance with U.S. GAAP. However, Sony believes that these disclosures provide additional useful analytical information to investors regarding the operating performance of Sony.

The following schedules show unaudited condensed balance sheets for the Financial Services segment and all other segments excluding Financial Services. These presentations are not in accordance with U.S. GAAP, which is used by Sony to prepare its consolidated financial statements.

As of March 31, 2020, Sony Life had debt securities with gross unrealized losses of 6.6 billion yen. Of the unrealized loss, 7.1% related to securities in an unrealized loss position for periods greater than 12 months as of March 31, 2020. Sony Life principally invests in Japanese and foreign government and corporate bonds. Almost all of the debt securities in which Sony Life invested were rated higher than or equal to “BBB” or its equivalent by Standard & Poor’s Ratings Services (“S&P”), Moody’s Investors Service (“Moody’s”) or other rating agencies.

As of March 31, 2020, Sony Bank had debt securities with gross unrealized losses of 2.5 billion yen. Of the unrealized loss, 4.3% related to securities in an unrealized loss position for periods greater than 12 months as of March 31, 2020. Sony Bank principally invests in Japanese government bonds, Japanese corporate bonds, and foreign bonds. Almost all of these securities were rated higher than or equal to “BBB” or its equivalent by S&P, Moody’s or other rating agencies.

These unrealized losses related to numerous investments, with no single investment being in a material unrealized loss position for greater than 12 months. In addition, there was no individual security with unrealized losses that met the test for impairment as the decline in values were small both in amount and percentage, and the decline in values for those investments were still determined to be temporary in nature.

For the fiscal years ended March 31, 2019 and 2020, Sony Life recorded no net realized gains on

available-for-sale

securities.

In the ordinary course of business, Sony maintains long-term investment securities, included in securities investments and other, issued by various

non-public

companies. The aggregate carrying amount of the investments in

non-public

companies as of March 31, 2020 was 30.1 billion yen. A

non-public

equity investment is measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment in the same issuer.

For the fiscal years ended March 31, 2019 and 2020, total realized impairment losses were 4.3 billion yen and 9.1 billion yen, respectively, of which 0.02 billion yen and 0.02 billion yen, respectively, were recorded in financial services revenue by the subsidiaries in the Financial Services segment. Realized impairment losses recorded other than by subsidiaries in the Financial Services segment in each of the two fiscal years were reflected in

non-operating

expenses and primarily relate to certain strategic investments in

non-Financial

Services businesses. These investments primarily relate to certain strategic investments in Japan and the U.S. with which Sony has strategic relationships for the purposes of developing and marketing new technologies. Impairment losses were recorded for each of the two fiscal years as certain companies failed to successfully develop and market such technology, resulting in the operating performance of these companies being more unfavorable than previously expected. As a result, the decline in the fair value of these companies was judged as other-than-temporary. None of these impairment losses were individually material to Sony.

Upon determination that the value of an investment is impaired, the value of the investment is written down to its fair value. For an investment where the quoted price is available in an active market, fair value is determined based on unadjusted quoted prices as of the date on which the impairment determination is made. For investments where the quoted price is not available in an active market, fair value is usually determined based on quoted prices of securities with similar characteristics or measured through the use of various methodologies such as pricing models, discounted cash flow techniques, or similar techniques that require significant management judgment or estimation of assumptions that market participants would use in pricing the investments. The impairment losses that were recorded in each of the two fiscal years related to the unique facts and circumstances of each individual investment and did not significantly impact other investments.

Sony Life and Sony Bank’s investments constitute the majority of the investments in the Financial Services segment. As of March 31, 2020, Sony Life and Sony Bank account for approximately 93% and 6% of the investments in the Financial Services segment, respectively.

Cash Flows

Operating Activities: During the current fiscal year ended March 31, 2020, there was a net cash inflow of 1 trillion 349.7 billion yen from operating activities, an increase of 91.0 billion yen

year-on-year.

For all segments excluding the Financial Services segment, there was a net cash inflow of 762.9 billion yen, an increase of 9.4 billion yen

year-on-year.

This increase was primarily due to an increase in net income after taking into account

non-cash

adjustments (including depreciation and amortization, other operating (income) expense, net and (gain) loss on securities investments, net, as well as the impact of the reversal of valuation allowances against deferred tax assets in Sony Americas Holdings Inc. and its U.S. consolidated tax group in the previous fiscal year) as well as a larger

year-on-year

decrease in notes and accounts receivable, trade and contract assets. This increase in net cash inflow was partially offset by the negative impact of a decrease in accounts payable, trade compared to an increase in the previous fiscal year.

Table of Contents

The Financial Services segment had a net cash inflow of 604.2 billion yen, an increase of 82.6 billion yen

year-on-year.

This increase was primarily due to a

year-on-year

increase in net income after taking into account

non-cash

adjustments such as depreciation and amortization, including amortization of deferred insurance acquisition costs and contract costs.

Investing Activities: During the current fiscal year ended March 31, 2020, Sony used 1 trillion 352.3 billion yen of net cash in investing activities, an increase of 44.8 billion yen

year-on-year.

For all segments excluding the Financial Services segment, there was a net cash outflow of 363.1 billion yen, a decrease of 157.3 billion yen

year-on-year.

This decrease was mainly due to the cash inflow from the sale of all of Sony’s shares of Olympus Corporation, as well as the absence of payment for the purchase of the approximately 60% equity interest of EMI that occurred in the previous fiscal year. This decrease in net cash outflow was partially offset by an increase in payments for purchases of fixed assets. Additionally, the previous fiscal year included net cash inflow resulting from the sale of certain shares of Spotify.

The Financial Services segment used 989.1 billion yen of net cash in investing activities, an increase of 202.0 billion yen year on year. This increase was mainly due to a

year-on-year

increase in payments for investments and advances carried out at Sony Life.

Financing Activities: Net cash inflow from financing activities during the current fiscal year was 65.7 billion yen, compared to net cash outflow of 122.9 billion yen in the previous fiscal year.

For all segments excluding the Financial Services segment, there was a 377.1 billion yen net cash outflow, a decrease of 144.0 billion yen

year-on-year.

This decrease was mainly due to the

decrease in the redemption of straight bonds and the repayment of long-term debt, as well as funds raised through the issuance of straight bonds in October 2019, partially offset by a payment related to the repurchases of shares of Sony’s own common stock (33,059,200 shares for a total purchase price of 200.0 billion yen) which was approved at the meeting of its Board of Directors held on May 16, 2019.

In the Financial Services segment, there was a 425.3 billion yen net cash inflow, an increase of 43.4 billion yen year on year. This increase was primarily due to an increase in short-term borrowings at Sony Life.

Accounting for the above factors and the effect of fluctuations in foreign exchange rates, the total outstanding balance of cash and cash equivalents at March 31, 2020 was 1 trillion 512.4 billion yen. Cash and cash equivalents of all segments excluding the Financial Services segment was 962.3 billion yen at March 31, 2020, an increase of 1.8 billion yen compared with the balance as of March 31, 2019. Within the Financial Services segment, the outstanding balance of cash and cash equivalents was 550.0 billion yen at March 31, 2020, an increase of 40.4 billion yen compared with the balance as of March 31, 2019.

Information on Cash Flows Separating Out the Financial Services Segment

The following schedules show unaudited condensed statements of cash flows for the Financial Services segment and all other segments excluding Financial Services. These presentations are not in accordance with U.S. GAAP, which is used by Sony to prepare its consolidated financial statements. However, because the Financial Services segment is different in nature from Sony’s other segments, Sony believes that a comparative presentation may be useful in understanding and analyzing Sony’s consolidated financial statements. Transactions between the Financial Services segment and Sony without the Financial Services segment, including noncontrolling interests, are included in those respective presentations, then eliminated in the consolidated figures shown below.

B.	Liquidity and Capital Resources

The description below covers basic financial policy and figures for Sony’s consolidated operations except for the Financial Services segment and SMN Corporation, which secure liquidity on their own. Furthermore, the Financial Services segment is described separately at the end of this section.

Liquidity Management and Market Access

An important financial objective of Sony is to maintain the strength of its balance sheet, while securing adequate liquidity for business activities. Sony defines its liquidity sources as the amount of cash and cash equivalents (“cash balance”) (excluding restrictions on capital transfers mainly due to national regulations) and the unused amount of committed lines of credit.

Funding requirements that arise from maintaining liquidity are principally covered by cash flow from operating and investing activities (including asset sales) and by the available cash balance; however, Sony also raises funds as needed from financial and capital markets through means such as corporate bonds, commercial paper (“CP”) and bank loans.

Sony Corporation, SGTS and Sony Capital Corporation (“SCC”), a finance subsidiary in the U.S., maintain CP programs with access to the Japanese, U.S. and European CP markets. The borrowing limits under these CP programs, translated into yen, were 1,044.2 billion yen in total for Sony Corporation, SGTS and SCC as of March 31, 2020. There were no amounts outstanding under the CP programs as of March 31, 2020.

If disruption and volatility occur in financial and capital markets and Sony becomes unable to raise sufficient funds from these sources, Sony may also draw down funds from contractually committed lines of credit from various financial institutions. Sony has a total, translated into yen, of 517.1 billion yen in unused committed lines of credit, as of March 31, 2020. Details of those committed lines of credit are: a 275.0 billion yen committed line of credit contracted with a syndicate of Japanese banks, a 1.7 billion U.S. dollar multi-currency committed line of credit also contracted with a syndicate of Japanese banks and a 525 million U.S. dollar multi-currency committed line of credit contracted with a syndicate of foreign banks. The above 525 million U.S. dollar committed line with a syndicate of foreign banks was renewed as of April 1, 2020 and increased to 1,050 million U.S. dollars. Sony currently believes that it can sustain sufficient liquidity through access to committed lines of credit with financial institutions, together with its available cash balance, even in the event that financial and capital markets become illiquid.

In the event of a downgrade in Sony’s credit ratings, there are no financial covenants in any of Sony’s material financial agreements with financial institutions that would cause an acceleration of the obligation. Even though the cost of borrowing for some committed lines of credit could change according to Sony’s credit ratings, there are no financial covenants that would cause any impairment on the ability to draw down on unused facilities.

Ratings

Sony considers one of management’s top priorities to be the maintenance of stable and appropriate credit ratings in order to ensure financial flexibility for liquidity and capital management and continued adequate access to sufficient funding resources in the financial and capital markets.

In order to facilitate access to global capital markets, Sony obtains credit ratings from two rating agencies, Moody’s and S&P. In order to facilitate access to Japanese financial and capital markets, Sony obtains credit ratings from two agencies in Japan, Rating and Investment Information, Inc. and Japan Credit Rating Agency, Ltd.

Sony currently believes that it has access to sufficient funding resources in the financial and capital markets. For information regarding a possible further rating downgrade, refer to “Risk Factors” in “Item 3.

Key Information

.”

Cash Management

Sony manages its global cash management activities primarily through SCC in the U.S. and through SGTS in other regions. The excess or shortage of cash at most of Sony’s subsidiaries is invested or funded by Sony Corporation, SGTS and SCC on a net basis, although Sony recognizes that fund transfers are limited in certain countries and geographic areas due to restrictions on capital transactions. In order to pursue more efficient cash

50

---

Table of Contents 

management, cash surpluses among Sony’s subsidiaries are deposited with SGTS and SCC, and cash shortfalls among subsidiaries are covered by loans through SGTS and SCC, so that Sony can make use of excess cash balances and reduce third-party borrowings. Where local restrictions prevent an efficient intercompany transfer of funds, Sony’s intent is that cash balances remain outside of SGTS and SCC and that Sony meet its liquidity needs through ongoing cash flows, external borrowings, or both. Sony does not expect restrictions of capital transactions on amounts held outside of Japan to have a material effect on Sony’s overall liquidity, financial condition or results of operations.

Financial Services segment

The management of SFH, Sony Life, Sony Assurance and Sony Bank recognizes the importance of securing sufficient liquidity to cover the payment of obligations that these companies incur in the ordinary course of business. Sony Life, Sony Assurance and Sony Bank maintain a sufficient cash balance and secure sufficient means to meet their obligations while abiding by laws and regulations such as the Insurance Business Act or the Banking Act of Japan, and restrictions imposed by the Financial Services Agency and other regulatory authorities as well as establishing and operating under company guidelines that comply with these regulations. Sony Life and Sony Assurance establish a sufficient level of liquidity for the smooth payment of insurance claims when they invest primarily in various securities cash inflows which are mainly from policyholders’ insurance premiums. Sony Bank maintains a necessary level of liquidity for the smooth settlement of transactions when it uses its cash inflows, which come mainly from customers’ deposits in local currency, in order to offer mortgage loans to individuals, and the remaining cash inflows are invested mainly in marketable securities. Cash inflows from customers’ deposits in foreign currencies are invested mainly in investment instruments of the same currency.

In addition, Sony’s subsidiaries in the Financial Services segment are subject to the Japanese Insurance Business Act and Banking Act, which require insurance and business companies to maintain their financial credibility and to secure protection for policyholders and depositors in view of the public nature of insurance and banking services. As such, lending and borrowing between subsidiaries in the Financial Service segment and the other companies within Sony Group is strictly limited. Sony’s subsidiaries in the Financial Services segment are managed separately from Sony’s cash management activities through SGTS as mentioned above.

For further information about Sony’s views regarding utilization of cash flow from operating activities generated within the Sony Group for strategic investments, shareholder returns and as cash on hand, refer to “Issues Facing Sony and Management’s Response to those Issues: Third

Mid-Range

Plan — Financial Targets and their Progress.”

C.	Research and Development

As a creative entertainment company with a solid foundation of technology, Sony promotes research and development (“R&D”) based on its mission to “fill the world with emotion through the power of technology.” Sony also believes that it is essential to align itself with the motivations of both creators and users in order to achieve its corporate direction of “getting closer to people.” In September 2019, Sony held the first Sony Technology Day, where it introduced cutting-edge technologies that connect the diverse businesses within the Sony Group. People are at the core of the Sony Group’s wide-ranging business portfolio, which is centered around the goals of “moving people’s hearts,” “connecting people to people” and “supporting people.” Sony plans to contribute to society through its technology as the societal significance of its businesses grows.

Through Corporate R&D (Sony’s research and development organization), Sony is realizing contributions to the entire Sony Group, setting the direction for robust technological development over the

mid-

to long-term, and enhancing open innovation. While supporting R&D activities in each business, Sony is connecting multiple businesses through technology as well as promoting initiatives in fields such as sensing, agent processing and output expression that contribute to differentiation in key areas. In carrying out Corporate R&D activities mainly focused on the next

three-to-ten

years, Sony shares the results of its research with the outside world as intellectual property, and then uses feedback from outside the company on that research to refine its development roadmap and periodically review how its R&D activities are aligned with its corporate strategy. From the standpoint of Sustainable Development Goals (SDGs) and Environment, Social and Governance (ESG), Sony also aims to contribute widely to society through technology, by delivering safety and security and by solving problems surrounding resources and the environment.

Sony carries out Corporate R&D activities in collaboration with multiple R&D centers in Japan, China, Europe and the United States, utilizing the different characteristics and strengths of each area. Additionally, Sony

51

Table of Contents

is proceeding with preparations to establish a new R&D center in India in an effort to strengthen its R&D presence overseas, and is also enhancing ease of movement for management and personnel between each R&D center and strengthening its R&D from more diverse perspectives. For cross-sectional projects such as those in the Entertainment and Financial Services areas, Sony assembles teams with members from various organizations to promote R&D activities through the flexible and efficient collection of knowledge. Sony is also proactively taking part in open innovation, including collaboration with universities and other research institutions, in an effort to gain insight into the motivations of creators and users from a wider perspective to enhance the potential of its business. 

R&D costs for the fiscal year ended March 31, 2020 increased by 18.1 billion yen to 499.3 billion yen. The ratio of R&D costs to total revenue excluding Financial Services was 7.2% compared to 6.5% in the previous fiscal year.

The following table includes R&D costs in the fiscal years ended March 31, 2019 and 2020.

		Fiscal year ended March 31

D.	Trend Information

This section contains forward-looking statements about the possible future performance of Sony and should be read in light of the cautionary statement on that subject, which appears on the inside front cover page and applies to this entire document.

Issues Facing Sony and Management’s Response to those Issues

The global economy remained sluggish during the first half of the fiscal year ended March 31, 2020 due to heightened geopolitical tensions such as intensifying U.S.-China trade friction and the withdrawal of Britain from the European Union (“Brexit”). In the second half of the fiscal year ended March 31, 2020, intermittent upturns in U.S.-China trade negotiations and decreased concerns about Brexit occurring without a withdrawal agreement (a

no-deal

Brexit) helped raise expectations that the deceleration of the global economy was bottoming out. However, the situation changed completely after the beginning of 2020 due to the spread of

COVID-19

around the world, and the global economy slowed rapidly toward the end of the fiscal year ended March 31, 2020. Currently, uncertainty in the outlook for the global economy is increasing due to difficulties predicting when the spread of

COVID-19

will diminish, and due to the reignition of trade friction between the U.S. and China.

Sony has a wide range of businesses globally. In addition to these changes in the global economy, changes in the business environment, such as increasingly intense pricing pressure from competitors, shrinking markets for certain key products and services, as well as shorter product cycles, are impacting each of Sony’s business segments. For further details about the business environment surrounding each business segment, refer to “Risk Factors” in “Item 3.

Key Information

” and “Operating Results” in “Item 5.

Operating and Financial Review and Prospects

.”

In this business environment, Sony has continued to prioritize management with a long-term view, and it has carried out initiatives such as promoting the evolution and growth of each business, as well as accelerating “One Sony” initiatives, with the goal of enhancing the corporate value of the entire Sony Group. These initiatives are based on Sony’s Purpose, which is to “fill the world with emotion through the power of creativity and technology,” as well as Sony’s corporate direction of “getting closer to people.” For details on the performance of each business segment in the fiscal year ended March 31, 2020, also refer to “Operating Results” in “Item 5.

Financial Services business to become a wholly-owned subsidiary

•

In order to achieve further growth and strengthen governance within the financial services business with the goal of enhancing the corporate value of the entire Sony Group, Sony Corporation resolved to make a tender offer for all of the common shares and related stock acquisition rights of SFH not held by Sony Corporation, of which it currently owns an approximately 65% stake, with a view to making SFH a wholly-owned subsidiary.

Third

Mid-Range

Plan — Financial Targets and their Progress

<Financial Targets>

On May 22, 2018, Sony Corporation unveiled a

mid-term

strategy (“third

mid-range

plan”) that charted the path forward for Sony over the next three years, starting with the fiscal year ended March 31, 2019 and finishing with the fiscal year ending March 31, 2021. In order to transition management of Sony’s operations to a more long-term perspective, key performance indicators were set as a cumulative total over a three-year period. In the third

mid-range

plan, cash flows from operating activities are the most important performance metric, and Sony has been targeting total cash flows from operating activities for all segments excluding the Financial Services segment of 2.2 trillion yen or more for the three-year period from the fiscal year ended March 31, 2019 to the fiscal year ending March 31, 2021. Sony believes that cash flows from operating activities are a performance metric suitable for Sony’s long-term management based on the following perspective: (i) it more appropriately represents the sustainable earnings power of a business because it does not include the effects of temporary profits and losses, and (ii) it is more easily comparable for the purpose of planning capital expenditure, strategic investment and dividends from management’s point of view. In terms of the allocation of cash generated (“capital allocation plan”), Sony planned to spend approximately 1.1 to 1.2 trillion yen on capital expenditure, as a result of greater investment in CMOS image sensors. Regarding the remaining 1 to 1.1 trillion yen, Sony planned to prioritize strategic investment, while also making an appropriate allocation to shareholder returns, in an effort to further enhance Sony’s corporate value. However, Sony is carefully reviewing its capital expenditure plans due to the uncertain market environment. In terms of dividends, Sony has intended to increase them in a stable and long-term manner. In addition, Sony has planned to maintain a Return on Equity (ROE) level of 10% or more.

<Progress>

Sony generated approximately 1.5 trillion yen of cumulative operating cash flow excluding the Financial Services segment from the fiscal year ended March 31, 2019 to the fiscal year ended March 31, 2020. Approximately 0.2 trillion yen in cash flow was also generated from the sale of businesses and assets. Sony prioritized using this cash to make investments for future growth, such as increasing CMOS image sensor manufacturing capacity and acquiring EMI. From the fiscal year ended March 31, 2019 to the fiscal year ended March 31, 2020, Sony used approximately 0.7 trillion yen of capital for its capital expenditures and approximately 0.9 trillion yen of capital as part of its strategy for strategic investment. The strategic investment was mainly comprised of approximately 390 billion yen of capital used to fully consolidate EMI, including the assumption of EMI’s interest-bearing debt, as well as 300 billion yen in repurchases of Sony’s own shares. In terms of share repurchases, Sony plans to consider engaging in share repurchases in a flexible manner after taking into account the balance between strategic investment opportunities and its financial situation and stock price in accordance with its view to emphasize growth in earnings per share (EPS). For the fiscal year ended March 31, 2019 and the fiscal year ended March 31, 2020, Sony achieved a ROE of 27.3% and 14.8%, respectively, resulting in maintaining the financial target of ROE of 10% or more.

Apart from the above-mentioned capital allocation plan, Sony also plans to use approximately 400 billion yen of capital from the financial and capital markets for a series of transactions, including a tender offer, to make SFH a wholly-owned subsidiary. However, depending on Sony’s cash position, there is a possibility that cash on hand could be allocated for a portion of this transaction.

Corporate Policy Regarding the Spread of

COVID-19

Sony is primarily focused on ensuring the safety of its employees and their families, as well as its customers and other stakeholders, in addition to preventing the further spread of the virus. Sony is also striving to answer the needs of society and its customers to the best of its ability, and to minimize the impact of the virus on its business. To accomplish these objectives, Sony is working to gather information and swiftly carry out necessary actions. As discussed above, Sony is also continuing to fulfill its social responsibility as a global company through various measures such as establishing a relief fund to support people around the world who have been affected by the spread of

COVID-19.

Group Environmental

Mid-Term

Targets “Green Management 2020”

Sony Corporation announced in June 2015 the establishment of its “Green Management 2020” group environmental

mid-term

targets, effective from fiscal 2016 (the fiscal year ended March 31, 2017) through fiscal 2020 (the fiscal year ending March 31, 2021). Based on the following three pillars, Sony has been implementing various initiatives to reduce the Sony Group’s environmental footprint:

•

Formulate targets and implement initiatives that leverage the distinctive characteristics of Sony’s businesses. Among these, reduce annual energy consumption by an average of 30% (compared to levels at the fiscal year ended March 31, 2014) in its products in the G&NS, EP&S and I&SS segments, and in the Music and Pictures segments, continue to look to use its content to raise awareness of sustainability issues and inspire environmentally conscious actions;

•

Enhance efforts to reduce Sony’s environmental footprint across its entire value chain, including manufacturing partners and suppliers, by calling on them to reduce greenhouse gas (GHG) emissions and water consumption; and

•

Accelerate the use of renewable energy.

Sony’s long-term vision is to achieve a “zero environmental footprint” throughout all stages of its product lifecycles and business activities by 2050. The “Green Management 2020”

mid-term

plan has been backcasted (calculated backwards) in order to determine the necessary intermediate steps that need to be taken by fiscal 2020 on the way to this long-term goal. With “Green Management 2020,” Sony plans to further accelerate its various initiatives directed towards its ultimate goal of a “zero environmental footprint.” As part of this measure Sony Corporation has joined RE100, an initiative operated by the international

non-government

organization (NGO) The Climate Group, in partnership with CDP. In so doing, Sony will aim to use 100% renewable electricity for all of its business sites by 2040.

Sony Corporation also plans to continue to participate in the WWF’s Climate Savers Programme, which aims to achieve reductions in greenhouse gas emissions. Climate change targets are verified by WWF and a third-party verification body for their degrees of difficulty and progress.

Further details of the group environmental

mid-term

targets “Green Management 2020” and actual measures undertaken by Sony are reported in Sony’s Sustainability report available on the following website: https://www.sony.net/SonyInfo/csr_report/.

E.	Off-balance Sheet Arrangements

Sony has certain

off-balance

sheet arrangements that provide liquidity, capital resources and/or credit risk support.

Refer to Note 6 of the consolidated financial statements for transfers of financial asset transactions in which Sony has relinquished control of receivables and accounted for these transfers as sales, and Note 24 of the consolidated financial statements for various arrangements with variable interest entities, including those where Sony is not the primary beneficiary and therefore does not consolidate the entity.

* Future insurance policy benefits and other and policyholders’ account in the life insurance business are the estimated future cash payments to be made to policyholders and others. These cash payments are based upon assumptions including morbidity, mortality, withdrawals and other factors. The sum of the cash payments shown for all years in the table of 26,457.4 billion yen exceeds the corresponding liability amount of 9,824.9 billion yen included in the consolidated balance sheets as of March 31, 2020. Refer to Note 10 of the consolidated financial statements.

** The total amount represents the liability for gross unrecognized tax benefits in accordance with the accounting guidance for uncertain tax positions. The settlement period for the liability, which totaled 41.3 billion yen, cannot be reasonably estimated due to the uncertainty associated with the timing of the settlements with the various taxing authorities. Refer to Note 22 of the consolidated financial statements.

The following items are not included in either the above table or the total amount of commitments outstanding as of March 31, 2020:

•

The total amount of expected future pension payments is not included as such amount is not currently determinable. Sony expects to contribute approximately 2 billion yen to Japanese defined benefit pension plans and approximately 8 billion yen to foreign defined benefit pension plans during the fiscal year ending March 31, 2021. Refer to Note 15 of the consolidated financial statements.

•

The total unused portion of the line of credit extended under loan agreements in the Financial Services segment is not included in the above table as it is not foreseeable what loans will be incurred under such line of credit. The total unused portion of the line of credit extended under these contracts was approximately 34.3 billion yen as of March 31, 2020. Refer to Note 28 of the consolidated financial statements.

•

Purchases made during the ordinary course of business from certain component manufacturers and contract manufacturers in order to establish the best pricing and continuity of supply for Sony’s production are not included as there are typically no binding purchase obligations. Purchase obligations are defined as contractual obligations to purchase goods or services that are enforceable and legally binding on Sony. These obligations specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. Purchase obligations do not include contracts that may be cancelled without penalty. These purchases include arrangements with certain component manufacturers whereby Sony procures goods, including product components, for these component manufacturers and is reimbursed for the related purchases. This allows Sony’s supply chain management to have flexible and mutually beneficial purchase arrangements with these manufacturers in order to minimize inventory risk. Consistent with industry practice, Sony purchases processed goods that meet technical criteria from these component manufacturers after issuing to these manufacturers information on Sony’s projected demand and manufacturing needs.

Refer to Item 8 A. “Consolidated Statements and Other Financial Information” for legal proceedings and Note 28 of the consolidated financial statements for guarantees issued, including product warranties.

Critical Accounting Policies and Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, Sony evaluates its estimates, which are based on historical experience, future projections and various other assumptions that are believed to be reasonable under the circumstances. The results of these evaluations form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of expenses that are not readily apparent from other sources. Actual results may significantly differ from these estimates. The timing and extent to which the spread of

COVID-19

may negatively impact Sony’s business will depend on future developments, which are highly uncertain. This uncertainty could result in greater variability in accounting estimates and assumptions, including, but not limited to, those used in reviewing goodwill and long-lived assets for impairment and the valuation of deferred tax assets. Sony considers an accounting policy to be critical if it is important to its financial condition and results, and requires significant judgment and estimates on the part of management in its application. Sony believes that the following represents its critical accounting policies.

Investments

Sony’s investments include debt and equity securities accounted for under both the cost and equity method of accounting. If it has been determined that an investment has sustained an other-than-temporary decline in its value, the investment is written down to its fair value with a charge to income. Sony regularly evaluates its investment portfolio to identify other-than-temporary impairments of individual debt securities. Factors that are considered by Sony in determining whether an other-than-temporary decline in value has occurred include: the length of time and extent to which the market value of the security has been less than its original cost, the financial condition, operating results, business plans and estimated future cash flows of the issuer of the security, other specific factors affecting the market value, deterioration of the credit condition of the issuer, sovereign risk, and whether or not Sony is able to retain the investment for a period of time sufficient to allow for the anticipated recovery in market value.

In evaluating the factors for debt securities designated as

available-for-sale,

Sony presumes a decline in value to be other-than-temporary if the fair value of the security is 20% or more below its original cost for an extended period of time (generally for a period of up to six months). This criterion is employed as a threshold to identify securities which may have a decline in value that is other-than-temporary. The presumption of an other-than-temporary impairment in such cases may be overcome if there is evidence to support that the decline is temporary in nature due to the existence of other factors which overcome the duration or magnitude of the decline. On the other hand, there may be cases where impairment losses are recognized when the decline in the fair value of the security is not more than 20% or such decline has not existed for an extended period of time, as a result of considering specific factors which may indicate that the decline in the fair value is other-than-temporary. 

When an other-than-temporary impairment of a

held-to-maturity

debt security has occurred, the amount of the other-than-temporary impairment recognized in income depends on whether Sony intends to sell the debt

59

---

Table of Contents

security or more likely than not will be required to sell the debt security before recovery of its amortized cost. If the debt security meets either of these two criteria, the other-than-temporary impairment is recognized in income, measured as the entire difference between the security’s amortized cost and its fair value at the impairment measurement date. For an other-than-temporary impairment of a debt security that does not meet these two criteria, the net amount recognized in income is a credit loss, which equals the difference between the amortized cost of the debt security and its net present value calculated by discounting Sony’s best estimate of projected future cash flows at the effective interest rate implicit in the debt security prior to impairment. Any difference between the fair value and the net present value of the debt security at the impairment measurement date is recorded in accumulated other comprehensive income. Unrealized gains or losses on securities for which an other-than-temporary impairment has been recognized in income are presented as a separate component of accumulated other comprehensive income.

The assessment of whether a decline in the value of an investment is other-than-temporary is often subjective in nature and involves certain assumptions and estimates concerning the expected operating results, business plans and future cash flows of the issuer of the security. Accordingly, it is possible that investments in Sony’s portfolio that have had a decline in value that Sony currently believes to be temporary may be determined to be other-than-temporary in the future based on Sony’s evaluation of subsequent information such as continued poor operating results, future broad declines in the value of worldwide equity markets and the effect of worldwide interest rate fluctuations. As a result, unrealized losses recorded for investments may be recognized and reduce income in future periods.

Valuation of inventory

Sony values its inventory based on the lower of cost and net realizable value. Sony writes down inventory in an amount equal to the difference between the cost of the inventory and the net realizable value — i.e., estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal. Sony writes down the value of its inventory when the underlying parts, components or products have become obsolete, when inventory levels exceed the amount expected to be used, or when the value of the inventory is otherwise recorded at a higher value than net realizable value. As a result, if actual market conditions are less favorable than projected and further price decreases are needed, additional inventory write-downs may be required in the future.

Impairment of long-lived assets

Sony reviews the recoverability of the carrying value of its long-lived assets held and used and long-lived assets to be disposed of, whenever events or changes in circumstances indicate that the carrying value of the assets or asset groups may not be recoverable. Long-lived assets to be held and used are reviewed for impairment by comparing the carrying value of the asset or asset group with their estimated undiscounted future cash flows. This review is primarily performed using estimates of future cash flows by product category or, in certain cases, by entity. If the carrying value of the asset or asset group is considered impaired, an impairment charge is recorded for the amount by which the carrying value of the asset or asset group exceeds its fair value. Fair value is determined using the present value of estimated net cash flows or comparable market values. This approach uses significant estimates and assumptions including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates applied to determine terminal values, determination of appropriate market comparables and the determination of whether a premium or discount should be applied to comparables.

Management believes that the estimates of future cash flows and fair values are reasonable, including, but not limited to, the potential impacts arising from the spread of

COVID-19.

As the extent and duration of the impacts from

COVID-19

remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower future cash flows and fair values due to unforeseen changes in Sony’s businesses or assumptions could negatively affect the valuations of long-lived assets.

Business combinations

When Sony applies the acquisition method of accounting, the deemed purchase price is allocated to identifiable assets acquired and liabilities assumed. Any residual purchase price is recorded as goodwill. The allocation of the purchase price utilizes significant estimates in determining the fair values of assets acquired and liabilities assumed, especially with respect to intangible assets. Independent third-party appraisal firms are typically engaged in order to assist in the estimation process. The significant estimates and assumptions include,

60

Table of Contents 

but are not limited to, the timing and amount of revenue and future cash flows, the discount rate reflecting the risk inherent in future cash flows and the perpetual growth rate used to calculate the terminal value. 

Due to the inherent uncertainties involved in making the estimates and assumptions, the purchase price for acquisitions could be valued and allocated to the acquired assets and liabilities differently. Actual results may differ, or unanticipated events and circumstances may affect such estimates, which could require Sony to record an impairment of an acquired asset, including goodwill, or increase in the amounts recorded for an assumed liability.

Goodwill and other intangible assets

Goodwill and indefinite lived intangible assets are tested annually for impairment during the fourth quarter of the fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. Such an event or change in circumstances would include unfavorable variances from established business plans, significant changes in forecasted results or volatility inherent to external markets and industries, which are periodically reviewed by Sony’s management.

In the fourth quarter of the fiscal year ended March 31, 2020, Sony elected not to perform an optional qualitative assessment of goodwill and instead proceeded directly to a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. Reporting units are Sony’s operating segments or one level below the operating segments. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the total amount of goodwill allocated to the reporting unit. Indefinite lived intangible assets are tested for impairment by comparing the fair value of the intangible asset with its carrying value, and if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Determining the fair value of a reporting unit under the goodwill impairment test is judgmental in nature and often involves the use of significant estimates and assumptions. Similarly, estimates and assumptions are used in determining the fair value of indefinite lived intangible assets. These estimates and assumptions could significantly impact whether or not an impairment charge is recognized as well as the magnitude of any such charge.

In its impairment review, Sony performs internal valuation analyses or utilizes third-party valuations when management believes it to be appropriate, and considers other market information that is publicly available. The fair value of a reporting unit or indefinite lived intangible asset is generally determined using a discounted cash flow analysis. This approach uses significant estimates and assumptions including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, earnings multiples, the determination of appropriate comparable entities and the determination of whether a premium or discount should be applied to comparables. Consideration is also given to Sony’s market capitalization in relation to the sum of the calculated fair values of the reporting units, including reporting units with no goodwill, and taking into account corporate level assets and liabilities not assigned to individual reporting units as well as a reasonable control premium.

The assumptions used for projected future cash flows and the timing of such cash flows are based on the forecast and

mid-range

plan (“MRP”) of each reporting unit and take into account such factors as historical experience, market and industry information, and current and forecasted economic conditions. Perpetual growth rates are utilized to determine a terminal cash flow value and are generally set after the three-year forecasted period for the MRP. Certain reporting units, such as those in the Pictures segment, utilize longer forecast periods and base the terminal value on an exit price using an earnings multiple applied to the final year of the forecasted earnings, which also takes into consideration a control premium. Discount rates are derived from the weighted average cost of capital of market participants in similar businesses.

For all reporting units with goodwill, fair value exceeded the carrying amount, and therefore no impairment existed in the fiscal year ended March 31, 2020. Also, fair value of reporting units with significant goodwill exceeded their respective carrying values by at least 10.0%. For indefinite lived intangible assets, fair value exceeded the carrying amount, and therefore no impairment existed.

Table of Contents

The carrying amounts of goodwill by segment as of March 31, 2020 are as follows:

		Yen in millions
Game & Network Services			170,974
Music			391,325
Pictures			152,374
Electronics Products & Solutions			12,189
Imaging & Sensing Solutions			46,192
Financial Services			10,834
Total			783,888

A discussion of the significant assumptions, other than the MRP described above, including a sensitivity analysis with respect to their impact, of the fair value of Sony’s reporting units for the impairment analysis performed for the fiscal year ended March 31, 2020 is included below:

•

The discount rates ranged from 5.2% to 10.8%. A hypothetical one percentage point increase in the discount rate, holding all other assumptions constant, would not have resulted in an impairment.

•

The growth rates applied to the terminal values for reporting units within the G&NS, EP&S and I&SS and Financial Services segments ranged from approximately 1.0% to 1.5%. The growth rates beyond the MRP period for the reporting units in the Music segment ranged from 0% to 5.2%, and in the Pictures segment ranged from 3.0% to 4.5%. A hypothetical one percentage point decrease in the growth rate, holding all other assumptions constant, would not have resulted in an impairment.

•

The earnings multiple used to calculate the terminal value in the Pictures reporting units ranged from 9.0x to 10.0x. A hypothetical reduction in the earnings multiple by 1.0x, holding all other assumptions constant, would not have resulted in an impairment.

Management believes that the assumptions used to estimate the fair value in the goodwill impairment tests are reasonable, including, but not limited to, the potential impacts arising from the spread of

COVID-19.

As the extent and duration of the impacts from

COVID-19

remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower than currently anticipated cash flows and fair values due to unforeseen changes in assumptions could negatively affect the valuations, which may result in Sony recognizing impairment charges for goodwill and indefinite lived intangible assets in the future.

Pension benefit costs

Employee pension benefit costs and obligations are dependent on certain assumptions including discount rates, retirement rates and mortality rates, which are based upon current statistical data, as well as expected long-term rates of return on pension plan assets and other factors. Specifically, the discount rate and expected long-term rate of return on pension plan assets are two critical assumptions in the determination of periodic pension costs and pension liabilities. Assumptions are evaluated at least annually, or at the time when events occur or circumstances change and these events or changes could have a significant effect on these critical assumptions.

In accordance with U.S. GAAP, actual results that differ from the assumptions are accumulated and amortized over future periods. Therefore, actual results generally affect recognized costs and the recorded obligations for pensions in future periods. While management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect Sony’s pension obligations and future costs.

Sony’s principal pension plans are its Japanese pension plans. No individual foreign pension plan is significant to the consolidated pension plan assets and pension obligations.

To determine the benefit obligation of the Japanese pension plans, Sony used a discount rate of 0.6% for its Japanese pension plans as of March 31, 2020. The discount rate was determined by using information about yields on high-quality bonds currently available and expected to be available during the period to maturity of the pension benefit obligation in consideration of amounts and timing of cash outflows for expected benefit payments. Such available information about yields is collected from published market information and credit rating agencies. The 0.6% discount rate is the same as the rate used for the fiscal year ended March 31, 2019 and reflects current Japanese market interest conditions.

Table of Contents

To determine the expected long-term rate of return on pension plan assets, Sony considers the current and expected asset allocations, as well as historical and expected long-term rates of return on various categories of pension plan assets. Sony’s pension investment policy recognizes the expected growth and the variability risk associated with the long-term nature of pension liabilities, the returns and risks of diversification across asset classes, and the correlation among assets. The asset allocations are designed to maximize returns consistent with levels of liquidity and investment risk that are considered prudent and reasonable. While the pension investment policy gives appropriate consideration to recent market performance and historical returns, the investment assumptions utilized by Sony are designed to achieve a long-term return consistent with the long-term nature of the corresponding pension liabilities. For Japanese pension plans, the expected long-term rate of return on pension plan assets was 2.6% and 2.5% as of March 31, 2019 and March 31, 2020, respectively. The actual return on pension plan assets for the fiscal years ended March 31, 2019 and 2020 was a 2.7% gain and a 1.3% gain, respectively. The difference between the expected and the actual rate of return on pension plan assets was primarily due to the negative performance in the global equity markets during the fourth quarter of the fiscal year ended March 31, 2020 due to the spread of

COVID-19.

Actual results that differ from the expected return on pension plan assets are accumulated and amortized as a component of pension costs over a certain period, thereby reducing the

year-to-year

volatility in pension costs. As of March 31, 2019 and March 31, 2020, Sony had, with respect to Japanese pension plans, net actuarial losses of 311.1 billion yen and 223.4 billion yen, respectively, including losses related to pension plan assets. Although the actual return on pension plan assets was lower than expected, the net actuarial loss decreased mainly due to the impact of the amendments to Japanese pension plans. Refer to Note 15 of the consolidated financial statements.

The following table illustrates the effect on the fiscal year ending March 31, 2021 of changes in the discount rate and the expected return on pension plan assets, while holding all other assumptions as of March 31, 2020 constant, for Japanese pension plans.

Deferred tax asset valuation

Carrying amounts of deferred tax assets require a reduction by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized prior to expiration. Accordingly, the need to establish a valuation allowance for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. Management’s judgments related to this assessment consider, among other matters, the nature, frequency and severity of current and cumulative losses on an individual tax jurisdiction basis, forecasts of future profitability after consideration of uncertain tax positions, excess of carrying value over the tax basis of net assets, the duration of statutory carryforward periods, the past utilization of net operating loss carryforwards prior to expiration, as well as prudent and feasible tax planning strategies which would be employed by Sony to prevent net operating loss and tax credit carryforwards from expiring unutilized.

As a result of prior losses, as of March 31, 2020, total established valuation allowances against deferred tax assets were 608.2 billion yen. This amount includes a valuation allowance of 274.8 billion yen relating to national tax and 125.5 million yen relating to local tax at Sony Corporation and its national tax filing group in Japan. A critical factor in the analysis of a continuing need for a valuation allowance against these assets is the forecast of future profitability given the relatively short net operating loss carryforward period in Japan. Due to the uncertainty of the forecast of future income after the impact of the spread of

COVID-19

from early 2020, the valuation allowance established against the net deferred tax assets that are attributable to Sony Corporation and its national tax filing group in Japan was not reversed, even partially, in the fiscal year ended March 31, 2020 despite several years of positive earnings. Valuation allowances also continue to be established on the remaining U.S. deferred tax assets of approximately 600 million U.S. dollars, primarily comprised of foreign tax credits and certain research and development credits. Sony continues to monitor its U.S. tax position and the potential use of such assets, and accordingly, the valuation allowance in respect of those assets may be reversed in the future.

Sony is subject to income taxes in Japan and numerous other jurisdictions, and in the ordinary course of business there are many situations where the ultimate tax determination can be uncertain, particularly with respect to transfer pricing for intercompany transactions. The amount of the deferred tax assets recorded takes

63

Table of Contents

into account the more likely than not final outcome of these uncertain tax positions based on Sony’s judgement, particularly for final allocations of taxable income among jurisdictions as a result of intercompany transfer pricing decisions. The estimate for the valuation of deferred tax assets, which is based on currently enacted tax laws and rates as of the balance sheet date, reflects management’s judgment and best estimate of the likely future tax consequences of events that have been recognized in Sony’s financial statements and tax returns, the ability to implement various tax planning strategies and, in certain cases, future forecasts, business plans and other expectations about future outcomes. Changes in existing tax laws or rates in tax jurisdictions in which Sony operates could affect actual tax results, and market or economic deterioration or failure of management to achieve its restructuring objectives could affect future business results, either of which could affect the valuation of deferred tax assets over time. If future results are less than projected, if the results of tax examinations or the negotiations of advance pricing agreements covering transfer pricing of intercompany transactions result in a different allocation of profits and losses than currently anticipated, if tax planning alternatives are no longer viable, or if there is no excess appreciated asset value over the tax basis of the assets contemplated for sale, further valuation allowance may be required in the future to reduce the deferred tax assets to their net realizable value. On the other hand, a forecasted improvement and consistency in future earnings or other factors, such as business reorganizations, could lead to the future reversal of valuation allowance into income as a reduction to tax expense, subject to review of the relevant qualitative factors and uncertainties. These factors and other changes that are not anticipated in current estimates could have a material impact on Sony’s earnings or financial condition in the period or periods in which the impact is recorded or reversed.

The U.S. Tax Reform Act significantly changed how the U.S. taxes corporations. The U.S. Tax Reform Act requires complex computations to be performed that were not previously required by U.S. tax law, significant judgments to be made in interpretation of the provisions of the U.S. Tax Reform Act, significant estimates in calculations, and the preparation and analysis of information not previously relevant or regularly produced. The U.S. Treasury Department, the Internal Revenue Service, and other standard setting bodies will continue to interpret or issue guidance on how provisions of the U.S. Tax Reform Act will be applied or otherwise administered. As future guidance is issued, Sony may make adjustments to amounts that it previously recorded that may materially impact Sony’s financial statements in the period in which the adjustments are made.

Film accounting

An aspect of film accounting that requires the exercise of judgment relates to the process of estimating the total revenues to be received throughout a film’s life cycle. Such estimate of a film’s ultimate revenue is important for two reasons. First, while a film is being produced and the related costs are being capitalized, it is necessary for management to estimate the ultimate revenue, less additional costs to be incurred, including exploitation costs which are expensed as incurred, in order to determine whether the value of a film has been impaired and thus requires an immediate

write-off

of unrecoverable film costs. Second, the amount of film costs recognized as cost of sales for a given film as it is exhibited in various markets throughout its life cycle is based upon the proportion that current period actual revenues bear to the estimated ultimate total revenues.

Management bases its estimates of ultimate revenue for each film on several factors including the historical performance of similar genre films, the star power of the lead actors and actresses, the expected number of theaters at which the film will be released, anticipated performance in the home entertainment, television and other ancillary markets, and agreements for future sales. Management updates such estimates on a regular basis based on the actual results to date and estimated future results for each film. For example, a film that has resulted in lower than expected theatrical revenues in its initial weeks of release would generally have its theatrical, home entertainment and television distribution ultimate revenues adjusted downward; a failure to do so would result in the understatement of amortized film costs for the period.

Future insurance policy benefits

Liabilities for future insurance policy benefits, except the portion of liabilities for minimum guarantee benefits which is described below, which mainly relate to individual life insurance policies, are established in amounts adequate to meet the estimated future obligations of policies in force. These liabilities, which require significant management judgment and estimates, are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. Future policy benefits are computed using interest rates ranging from 0.5% to 4.5% and are based on factors such as market conditions and expected investment returns. Morbidity, mortality and withdrawal assumptions for all policies are based on either the subsidiary’s own experience or various actuarial tables. Generally these assumptions are

locked-in

throughout the life of the contract upon the issuance of new insurance, although significant changes in

64

Table of Contents

experience or assumptions may require Sony to provide for expected future losses. Liabilities for future policy benefits include the liability for the minimum guarantee benefits of variable annuities and variable life insurance contracts. Regarding variable annuities and variable life insurance contracts, minimum guarantee benefits (minimum death benefit, minimum accumulation benefit, etc.) are provided, and Sony bears the risk of fulfilling the minimum guarantee benefits prescribed in the contracts to policyholders. The fair value option is applied to a portion of the liabilities for the variable annuity contracts with minimum guarantee benefits. Refer to Note 13 of the consolidated financial statements. Excluding the portion of the liability measured at fair value, the liability for the minimum guarantee benefit is calculated based on the ratio of the present value of expected total excess payments divided by the present value of expected total assessments over the life of the contract. Mortality rates, lapse rates, discount rates and investment yield are used as significant assumptions for this calculation.

Policyholders’ account in the life insurance business

Policyholders’ account in the life insurance business represents an accumulation of account deposits plus credited interest less withdrawals, expenses and mortality charges. Policyholders’ account includes universal life insurance and investment contracts. Universal life insurance includes interest sensitive whole life contracts and variable life insurance contracts. The credited rates associated with interest sensitive whole life contracts range from 1.7% to 2.0%. For variable life insurance contracts, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. Investment contracts mainly include single payment educational endowment contracts, individual variable annuities and policies after the start of annuity payments. The credited rates associated with investment contracts, except for individual variable annuities, range from 0.01% to 6.3%. For individual variable annuities, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. Liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business. Refer to Note 13 of the consolidated financial statements.

*3 Sony Corporation does not pay remuneration linked to business results to Directors who do not concurrently serve as Corporate Executive Officers.

*1 The above chart shows remuneration for Directors and Corporate Executive Officers who received, or who became likely to receive, total remuneration exceeding 100 million yen from Sony Corporation and its subsidiaries during the fiscal year ended March 31, 2020. Titles are as of the date of submission of this document.

*2 Due to rounding, individual sums may not total 100%.

*3 For the indicators and results used to determine the amount of remuneration linked to business results, please refer to “Corporate Executive Officer remuneration linked to business results for the fiscal year ended March 31, 2020” below. 

*4 The weighted-average fair value per share at the date of grant of stock acquisition rights granted during the fiscal year ended March 31, 2020 was 1,864 yen and was estimated using the Black-Scholes option-pricing model with several assumptions. Refer to Note 17 of the consolidated financial statements for details. The weighted-average fair value per share does not indicate the actual value that would be realized by a Corporate Executive Officer upon the exercise of the above-mentioned stock acquisition rights. The actual value, if any, that is realized by a Corporate Executive Officer upon the exercise of any stock acquisition rights will depend on the extent to which the market value of Sony Corporation’s common stock (“Common Stock”) exceeds the exercise price of the stock acquisition rights on the date of exercise, and several other restrictions imposed on the exercise of the stock acquisition rights, including the period when a Corporate Executive Officer could exercise the stock acquisition rights. Accordingly, there is no assurance that the value realized or to be realized by a Corporate Executive Officer upon the exercise of the stock acquisition rights is or will be at or near the weighted-average fair value per share presented above. In addition, the above weighted-average fair value per share was calculated to recognize compensation expense for the fiscal year ended March 31, 2020 for accounting purposes and should not be regarded as any indication or prediction of Sony with respect to its future stock performance.

*5 Indicates the total number of shares of restricted stock granted in the fiscal year ended March 31, 2020 for Corporate Executive Officers. The issue price per share of restricted stock was 5,648 yen.

*6 As noted above, Sony Corporation does not pay any remuneration for services as a Director to Directors who concurrently serve as Corporate Executive Officers.

*7 Apart from the remuneration contained in the above table, Sony Corporation also provided certain personal benefits and perquisites, including fringe benefits and in some instances income taxes related to perquisites, totaling 8 million yen to Kenichiro Yoshida, 1 million yen to Hiroki Totoki and 1 million yen to Toru Katsumoto during the fiscal year ended March 31, 2020.

*8 In the above chart, remuneration for Toru Katsumoto includes 13 million yen in fixed compensation and 9 million yen in performance-based compensation from Sony Imaging Products & Solutions Inc.

(3) Basic policy regarding Director and Senior Executive remuneration

The basic policy regarding remuneration for Directors and Senior Executives determined by the Compensation Committee, is as follows:

(a) Basic policy regarding Director remuneration

The primary duty of Directors is to supervise the performance of business operations of Sony as a whole. In order to improve this supervisory function over the business operations of Sony, which is a global company, the following two elements have been established as the basic policy for the determination of remuneration of Directors. No Director remuneration is paid to those Directors who concurrently serve as Corporate Executive Officers.

•

Attracting and retaining an adequate talent pool of Directors possessing the requisite abilities to excel in the global marketplace; and

•

Ensuring the effectiveness of the supervisory function of Directors.

Based upon the above, Director remuneration consists of the following three components:

•

Fixed remuneration;

•

Remuneration linked to stock price; and

•

Phantom Restricted Stock Plan.

The amount of each component and its percentage of total remuneration shall be at an appropriate level determined in accordance with the basic policy above and based upon research conducted by a third party regarding remuneration of directors of both Japanese and

non-Japanese

companies.

Regarding remuneration linked to stock price, restricted stock is used to further promote shared values between the shareholders and Directors, and incentivize Directors to develop and maintain a sound and transparent management system. Appropriate restrictions and conditions shall be set in order to enhance the effectiveness of the remuneration programs.

Regarding the Phantom Restricted Stock Plan, points determined every year by the Compensation Committee shall be granted to Directors every year during his/her tenure, and at the time of resignation, the remuneration amount shall be calculated by multiplying the common stock price by the individual’s accumulated points. Sony shall not grant any points pursuant to the Phantom Restricted Stock Plan to a Director for a fiscal year in which Sony granted restricted stock as Director remuneration to such Director.

(b) Basic policy regarding Senior Executive remuneration

Senior Executives are key members of management responsible for executing the operations of Sony as a whole, or respective businesses of Sony. In order to further improve the business results of Sony, the following two elements have been established as the basic policy for the determination of remuneration of Senior Executives.

•

Attracting and retaining an adequate talent pool possessing the requisite abilities to excel in the global marketplace; and

•

Providing effective incentives to improve business results on a short-, medium- and long- term basis.

Based upon the above, Senior Executive remuneration shall basically consist of the following four components:

•

Fixed remuneration;

•

Remuneration linked to business results;

•

Remuneration linked to stock price; and

•

Phantom Restricted Stock Plan.

The amount of each component and its percentage of total remuneration shall be at an appropriate level determined in accordance with the above basic policy and the individual’s level of responsibility and based upon research conducted by a third party regarding remuneration of management of both Japanese and

non-Japanese

companies, emphasizing linking Senior Executive remuneration to business results and shareholder value. In principle, remuneration for a Senior Executive who has a greater management responsibility and influence on

73

Table of Contents

Sony as a whole has a higher proportion of remuneration linked to stock price which is directly linked to the corporate value. (Please see below Reference: Executive Compensation Package Design to Focus on Long-Term Management.)

Remuneration linked to business results shall be structured appropriately and based upon appropriate indicators to ensure that such remuneration effectively incentivizes Senior Executives to achieve the

mid-

to long-term and the corresponding fiscal year’s corporate targets. Specifically, the amount shall be determined based upon the level of achievements of the targets of (1) certain key performance indicators linked to consolidated or individual business results of Sony of the corresponding fiscal year, such as Return on Equity (“ROE”), Net Income attributable to Sony Corporation’s Stockholders and Operating Cash Flow (“Financial Performance KPIs”), which indicators are selected based on the areas for which each Senior Executive is responsible and (2) the individual performance of the area(s) for which the relevant Senior Executive is responsible. The amount to be paid to Senior Executives shall fluctuate, in principle, within the range from 0% to 200% of the standard payment amount (“Business Results Linked Standard Payment Amount”) based on the achievement of the above-mentioned targets. Efforts to accelerate collaboration among businesses of Sony from the viewpoint of value creation as “One Sony,” as well as sustainability initiatives related to social value creation and ESG (environment, social and governance) shall be included in the evaluation indicators of individual performance. The Business Results Linked Standard Payment Amount shall be determined so that such amount is within a certain percentage of the cash compensation (total of the fixed remuneration and the remuneration linked to business results), which percentage shall be determined in accordance with each individual’s level of responsibility.

Remuneration linked to the stock price, such as stock options and restricted stock, will be used to incentivize Senior Executives to increase

mid-

to long-term shareholder value. Appropriate restrictions and conditions shall be set in order to enhance the effectiveness of such remuneration program. The amount of remuneration linked to the stock price shall be determined, so that the amount is within a certain percentage of the total cash compensation (total of the fixed remuneration and the remuneration linked to business results) and remuneration linked to the stock price.

Regarding the Phantom Restricted Stock Plan, points determined every year by the Compensation Committee shall be granted to Senior Executives every year during his/her tenure in office, and at the time of resignation, the remuneration amount shall be calculated by multiplying the common stock price by the individual’s accumulated points.

(Reference: Executive Compensation Package Design to Focus on Long-Term Management)

The following bar chart shows the composition of remuneration for Senior Executives applicable to the fiscal year ended March 31, 2020. The proportions of “Remuneration linked to business results” are based on the Business Results Linked Standard Payment Amount.

 

(4) Procedures to determine remuneration of Directors and Senior Executives

Based on the policy outlined above, the Compensation Committee determines the amount and content of the compensation for each Director and Senior Executive. Specifically, in principle, each year at the meeting of the Compensation Committee held after the Ordinary General Meeting of the Shareholders, the amount of basic remuneration and the content of each Director’s and Senior Executive’s compensation for the corresponding fiscal year is determined. Thereafter, at the meeting of the Compensation Committee held after the corresponding fiscal year end, the final amount of compensation of each Director and Senior Executive is determined, including the amount of remuneration linked to business results.

For determining the amount of the remuneration linked to business results for each Senior Executive, the Business Results Linked Standard Payment Amount, the targets for the Financial Performance KPIs and the targets for the individual performance of the areas(s) for which each Senior Executive is responsible are

74

Table of Contents

determined and thereafter, at the meeting of the Compensation Committee held after the corresponding fiscal year end, the amount of such remuneration is determined based on the level of achievement of such targets for the Financial Performance KPIs and the individual performance.

The Compensation Committee determined the amount of compensation of each Directors and Senior Executives for the fiscal year ended March 31, 2020 also according to the procedure above.

(5) Corporate Executive Officer remuneration linked to business results for the fiscal year ended March 31, 2020

The Business Results Linked Standard Payment Amount for the fiscal year ended March 31, 2020 was between 37.5% and 50.0% of cash compensation (total of the fixed remuneration and the remuneration linked to business results). The Financial Performance KPIs mainly used for the Corporate Executive Officers and their weighting, targets and results were as follows:

KPI		Weight				Target to be achieved for the fiscal year ended March 31, 2020 (Consolidated)		Result for the fiscal year ended March 31, 2020 (Consolidated)
Operating CF			50%			Amount determined in order to achieve the Operating CF (as defined below) target under Sony’s Third Mid-Range Plan of 2.2 trillion yen or more for the three-year period from the fiscal year ended March 31, 2019			762.9 billion yen
Net Income  attributable to  Sony  Corporation’s  Stockholders			40%			500 billion yen			582.2 billion yen
ROE			10%			12.5%			14.8%

Operating cash flow, excluding the Financial Services Segment (“Operating CF”), was selected as a Financial Performance KPI and was weighed the highest due to operating cash flow being determined as the most important performance metric under the Third

Mid-Range

Plan of Sony. ROE was also selected due to it being one of the financial targets of Sony’s Third

Mid-Range

Plan. Net Income attributable to Sony Corporation’s Stockholders was selected in order to incentivize management to achieve the current fiscal year’s corporate target.

For the target to be achieved for the Operating CF for the fiscal year ended March 31, 2020, an amount which the Compensation Committee determined as appropriate was set in order to achieve the Operating CF target under Sony’s Third

Mid-Range

Plan of 2.2 trillion yen or more for the three-year period from the fiscal year ended March 31, 2019. The target for the Net Income attributable to Sony Corporation’s Stockholders for the fiscal year ended March 31, 2020 was set as 500 billion yen, which was the forecasted amount for the Net Income attributable to Sony Corporation’s Stockholders for the fiscal year ended March 31, 2020 announced in April 2019. The target for ROE was 12.5% for the fiscal year ended March 31, 2020. The results for the Financial Performance KPIs for the fiscal year ended March 31, 2020 were as follows: Operating CF: 762.9 billion yen, Net Income attributable to Sony Corporation’s Stockholders: 582.2 billion yen, ROE: 14.8%, each exceeding the targeted amount.

As outlined above under “Basic policy regarding Director and Senior Executive remuneration,” remuneration linked to business results for Corporate Executive Officers for the fiscal year ended March 31, 2020 was determined based upon the level of achievement of the indicators which were selected based on the areas of responsibility of the relevant Corporate Executive Officer and the individual performance of the area(s) for which the relevant Corporate Executive Officer was responsible. The amounts to be paid to the Corporate Executive Officers were determined within the range from 0% to 200% of the Business Results Linked Standard Payment Amount. As a result, the ratio of remuneration linked to business results of Corporate Executive Officers for the fiscal year ended March 31, 2020 was in the range of 149.1% to 155.1% of the Business Results Linked Standard Payment Amount.

(For Reference) Restricted Stock

Sony Corporation has introduced a restricted stock plan starting from the fiscal year ended March 31, 2018, pursuant to which shares of restricted stock will be allotted to Sony Corporation’s Corporate Executive Officers and other executives, and

non-executive

Directors of Sony Corporation (the

“Non-Executive

Directors”). The

75

---

Table of Contents

purpose of the plan for the Corporate Executive Officers and other executives is to further reinforce management’s alignment with shareholder value, and to incentivize management to improve

mid-

to long-term performance and increase shareholder value. Furthermore, the purpose of the plan for the

Non-Executive

Directors is to incentivize these Directors to develop and maintain a sound and transparent management system by further promoting shared values between the shareholders and the

Non-Executive

Directors.

The grantees will not be able to sell or transfer the granted shares during the restricted period, and Sony Corporation will acquire the granted shares from a grantee without any consideration to, or consent of, the grantee under certain conditions. Details of the plan, such as vesting conditions, eligibility and the number of grants, will be determined by the Compensation Committee.

C.	Board Practices

General

Sony Corporation continuously strives to strengthen its corporate governance system in a way that is suitable for Sony and increases corporate value over the

mid-

to long-term. To operate Sony effectively, Sony Corporation continuously approaches its corporate governance through two basic precepts: (a) the Board of Directors (the “Board”), a majority of which is comprised of independent outside Directors, focuses on effective oversight of management’s operation of the business and maintains a sound and transparent governance framework by utilizing the Nominating Committee, the Audit Committee and the Compensation Committee; and (b) the Board determines Sony’s fundamental management policies and other material matters and delegates to each of the Senior Executives that assume important roles for the management of Sony, including the Corporate Executive Officers, decision-making authority to conduct Sony’s business operations broadly in line with their respective responsibilities, as defined by the Board, with a view to promoting timely and efficient decision-making within Sony. In furtherance of these efforts, Sony Corporation has adopted a “Company with Three Committees” corporate governance system under the Companies Act of Japan (

Kaishaho

) and related regulations (collectively the “Companies Act”) as the most appropriate system for the company. Under such system, Sony Corporation has introduced its own requirements to help improve and maintain the soundness and transparency of its governance by strengthening the separation of the Directors’ function from that of management; maintaining what the company believes is an appropriate Board size, which enables the members of the Board to actively contribute to discussion; and advancing the proper functioning of the statutory committees.

Sony Corporation is governed by the Board, the members of which are elected at the Ordinary General Meeting of Shareholders. Under the Companies Act, a “Company with Three Committees” is required to have three committees: the Nominating Committee, the Audit Committee and the Compensation Committee, each consisting of Directors appointed by the Board. The Companies Act also requires the Board to appoint Corporate Executive Officers (

Shikko-yaku

), who make decisions regarding the execution of Sony’s business activities within the scope of the authority delegated to them by the Board. Sony Corporation has appointed its Chief Executive Officer (“CEO”), who is responsible for Sony’s overall management, and other officers who are responsible for important and extensive headquarters functions as Corporate Executive Officers. Sony Corporation has also appointed Corporate Executive Officers, including the CEO and other executives, that assume important roles for the management of Sony as Senior Executives. In addition, Sony grants titles, such as Senior Executive Vice President, Executive Vice President and Senior Vice President, to management team members in accordance with their respective roles and responsibilities.

A summary of the governance system adopted by Sony Corporation is set forth below. For an explanation of the significant differences between the New York Stock Exchange’s corporate governance standards and Sony’s corporate governance practices, refer to “Item 16G.

Support for Activities of Directors, the Board and the Committees

Sony Corporation engages in various activities to enhance the oversight function of the Board over management’s operation of Sony’s business as follows:

(1) Outside Director Initiatives

The Chairman of the Board is elected from among those Directors that are not also the Representative Corporate Executive Officer, and the Chairman leads the Board’s activities and secures the appropriate cooperation, communication and arrangement among outside Directors and Senior Executives. For example, the Board conducted outside Directors’ meetings, generally the same day as each Board Meeting was held.

All these activities were aimed at securing better understanding by outside Directors of Sony’s business and management’s initiatives and encouraging corporate strategic discussions among Directors.

(2) Secretariat Offices for the Board and each Committee

The company has established the secretariat offices of the Board and each Committee to support the activities of the members and encourage constructive and proactive discussion at the meetings of the Board and each Committee. Each secretariat office endeavors to distribute necessary materials for the meetings in advance and to provide other information such as accounting information, organizational charts, press releases, external analyst reports and credit rating reports, as appropriate. Each secretariat office explains the meeting agenda to the members and provides them with presentation materials in advance of each meeting date and facilitates deliberation in separate meetings or brief sessions depending on the nature of matters to be discussed. Each secretariat office also provides the absent members with a follow up briefing, as appropriate. In addition, each secretariat office shares the annual schedule of the meetings and anticipated agenda items in advance with the members, in order to appropriately set the frequency of meetings and the number of agenda items to be deliberated at each meeting.

(3) Provision of Necessary Information

When the company is requested to provide additional information, each secretariat office endeavors to provide the members such information promptly. Also, each secretariat office verifies appropriately whether requested information is provided smoothly. In the event that the members consult with external specialists, participate in various seminars and so on to perform their duties, the costs and expenses in connection with such activities are borne by the company in accordance with applicable internal rules.

(4) Audit Committee Aide

Evaluation of the Board and the Committees’ Effectiveness

(1) Policy for Evaluation

Sony Corporation believes that it is important to endeavor to improve the effectiveness of the Board and each Committee in order to support Sony’s business operations and enhance the corporate value of Sony. To achieve this goal, Sony Corporation conducts evaluations of the effectiveness of the Board and of each Committee (the “Evaluation”) at least annually.

(2) Recent Evaluation

From February through April 2020, the Board conducted the Evaluation mainly in respect of the Board and Committee activities in the fiscal year ended March 31, 2020 after confirming that actions proposed in response to the results of the previous Evaluation were appropriately taken. The recent Evaluation was conducted, as the company did with the previous Evaluation, with the support of a third-party evaluation by an outside counsel having expertise in Japanese and global corporate governance practices (the “Outside Counsel”) in order to ensure transparency and objectivity and to obtain professional advice.

(3) Procedures for Recent Evaluation

First, the Board discussed and confirmed that the actions proposed to be taken in response to the results of previous Evaluation were taken, and discussed and confirmed the proposed procedures for the Evaluation for the fiscal year ended March 31, 2020. Thereafter, the third-party evaluation was conducted by the Outside Counsel in accordance with the following steps:

•

Reviewed relevant material, such as the minutes of Board meetings, and attended a Board meeting;

 

 

•

Confirmed with the Board secretariat office and each Committee’s secretariat office how meetings of the Board and Committees were conducted;

 

 

•

Gathered responses to a questionnaire from each Director about the current status and practices of the Board and each Committee, such as the composition of the Board, operation of the Board, commitments of each Director, activities of each Committee and procedures of the previous Evaluation;

 

 

•

Interviewed the Chairman of the Board, newly-appointed Directors, a Director who is concurrently in the position of the CEO, and certain additional Directors about the Board and Committee status and practices; and

 

 

•

Researched other global companies’ practices in Japan, the United States and Europe, and compared them with the company’s practices.

 

 

The Board then received, reviewed and discussed the Outside Counsel’s report on the results of its evaluation. The Board confirmed the effectiveness of the Board and the Committees.

(4) Summary of the Results of Recent Evaluation

The Outside Counsel reported that the Board is established and operated in a manner sufficient to be highly appreciated, based on various points, including the self-evaluation results of the Directors and comparison with benchmarked companies in Japan, the United States and Europe. Following discussion and analysis based on the Outside Counsel’s report, the Board

re-affirmed

Internal Control and Governance Framework

At a Board meeting held on April 26, 2006, the Board reaffirmed the internal control and governance framework in effect as of the date of determination and determined to continue to evaluate and improve such framework going forward, as appropriate. At a Board meeting held on May 13, 2009 and April 30, 2015, the Board amended and updated the internal control and governance framework, and with the written resolution of the Board dated as of May 15, 2020, the Board reaffirmed such framework in effect and determined to continue to evaluate and improve such framework going forward, as appropriate. These determinations were required by and met the requirements of the Companies Act.

A summary of principal framework in the internal control and governance framework based on the Board determination above is as follows:

(1) Disclosure Control Framework

The securities of Sony Corporation are listed for trading on exchanges in Japan and the U.S. As a result, Sony is obligated to make various disclosures to the public in accordance with applicable securities laws, regulations and rules in those countries and listing standards of the stock exchanges on which Sony Corporation’s shares are listed. Sony is committed to full compliance with all requirements applicable to its public disclosures. Sony Corporation’s policy on investor relations activities is to aim to disclose accurate information in a timely and fair manner, as well as to endeavor to promote constructive dialogue with shareholders and investors, with a view to maximizing the corporate value by building a relationship of trust with shareholders and investors. Sony Corporation has in place disclosure controls and procedures in support of this policy. All personnel responsible for the preparation of submissions to and filings with the Tokyo Stock Exchange, the U.S. Securities and Exchange Commission and other regulatory entities, or for other public communications made on behalf of Sony, or who provide information as part of that process, have a responsibility to ensure that such disclosures and information are full, fair, accurate, timely and understandable, and in compliance with the established disclosure controls and procedures.

Sony Corporation has established “Disclosure Controls and Procedures,” outlining the process through which potentially material information is reported from important business units, subsidiaries, affiliated companies and corporate divisions and is reviewed and considered for disclosure in light of its materiality to Sony. As a body to assist the CEO and the CFO of Sony Corporation, in designing, implementing and evaluating the Disclosure Controls and Procedures, Sony Corporation has established the “Disclosure Committee,” which is comprised of members of senior management of Sony Corporation who are in charge of relevant departments. In order to assure appropriate and timely disclosure, the Disclosure Committee shall evaluate events that are reported from the important business units, subsidiaries, affiliated companies and corporate divisions in accordance with Sony’s internal rules in light of their materiality to Sony. Based on such evaluation, the Disclosure Committee shall review the necessity of disclosure in accordance with applicable securities laws, regulations and rules, as well as the listing standards of the relevant stock exchanges, and report to the CEO and CFO for their determination.

(2) Risk Management Framework

Each business unit, subsidiary/affiliated company and corporate division of Sony periodically reviews and assesses risks and establish and maintain necessary risk management systems (such as detection, communication,

evaluation and response) for the area of which they are in charge. In addition, Senior Executives, including the Corporate Executive Officers, of Sony Corporation have established and maintain a system to identify and control risks that may cause losses to Sony regarding the areas of which they are in charge. The Corporate Executive Officer in charge of group risk control shall comprehensively promote and manage the establishment and maintenance of the systems as stated above.

Legal Proceedings

Beginning in 2009, the U.S. Department of Justice, the European Commission and certain other governmental agencies outside the United States have conducted investigations relating to competition in the optical disk drives market. Sony Corporation and/or certain of its subsidiaries have been subject to these investigations. Sony Corporation understands that these investigations have ended. However, proceedings

87

Table of Contents

initiated by the European Commission as a result of its investigation continue. In October 2015, the European Commission adopted a decision in which it fined Sony Corporation and certain of its subsidiaries 31 million euros; however, Sony Corporation filed an appeal against the decision with the European Union’s General Court. In July 2019, the General Court upheld the European Commission’s decision. Sony Corporation reviewed the judgment carefully and filed an appeal with the Court of Justice of the European Union in September 2019. A number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceedings will not have a material impact on Sony’s results of operations and financial position.

Since 2011, in relation to the secondary batteries business that was operated by Sony Corporation and certain of its subsidiaries, a number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceeding will not have a material impact on Sony’s results of operations and financial position.

In addition, Sony Corporation and certain of its subsidiaries are defendants or otherwise involved in other pending legal and regulatory proceedings. However, based upon the information currently available, Sony believes that the outcome from such legal and regulatory proceedings would not have a material impact on Sony’s results of operations and financial position.

Dividend Policy

Sony believes that continuously increasing corporate value and providing dividends are essential to rewarding shareholders. It is Sony’s policy to utilize retained earnings, after ensuring the perpetuation of stable dividends, to carry out various investments that contribute to an increase in corporate value, such as those that ensure future growth and strengthen competitiveness. Going forward, Sony will determine the amount of dividends based on an overall consideration of Sony’s consolidated operating results, financial condition and future business expectations.

A fiscal

year-end

dividend of 25 yen per share of Common Stock of Sony Corporation was approved with the written resolution of the Board of Directors dated as of May 13, 2020 and the payment of such dividend started on June 5, 2020. Sony Corporation has already paid an interim dividend for Common Stock of 20 yen per share to each shareholder; accordingly, the total annual dividend per share of Common Stock for the fiscal year ended March 31, 2020 is 45 yen.

Directors

Under the Companies Act, because Sony Corporation has adopted the “Company with Three Committees” system, Directors have no power to execute the business of Sony Corporation except in limited circumstances as permitted by law. If a Director also serves concurrently as a Corporate Executive Officer, then he or she can execute the business of Sony Corporation in the capacity of Corporate Executive Officer. Under the Companies Act, Directors must refrain from engaging in any business competing with Sony Corporation unless approved by the Board of Directors, and any Director who has a material interest in the subject matter of a resolution to be taken by the Board of Directors cannot vote on such resolution. The amount of remuneration to each Director is determined by the Compensation Committee, which consists of Directors, the majority of whom are outside Directors (Refer to “Board Practices” in “Item 6.

”). No member of the Compensation Committee may vote on a resolution with respect to his or her own compensation as a Director or a Corporate Executive Officer.

Neither the Companies Act nor Sony Corporation’s Articles of Incorporation make a special provision as to the borrowing powers exercisable by Directors (subject to requisite internal authorizations as required by the Companies Act), their retirement age, or a requirement to hold any shares of capital stock of Sony Corporation.

Capital stock

(General)

Unless indicated otherwise, set forth below is information relating to Sony Corporation’s capital stock, including brief summaries of the relevant provisions of Sony Corporation’s Articles of Incorporation and Share Handling Regulations, currently in effect, and of the Companies Act and related regulations.

On January 5, 2009, a central book-entry transfer system for shares of Japanese listed companies was established pursuant to the Act Concerning Book-entry Transfer of Corporate Bonds, Shares, etc. (including regulations promulgated thereunder, “Book-entry Transfer Act”), and this system is applied to the shares of Common Stock of Sony Corporation. Under this system, shares of all Japanese companies listed on any Japanese stock exchange are dematerialized, and shareholders must have accounts at account management institutions to hold their shares unless such shareholder has an account at Japan Securities Depository Center, Inc. (“JASDEC”). “Account management institutions” are financial instruments traders (i.e., securities companies), banks, trust companies and certain other financial institutions that meet the requirements prescribed by the Book-entry Transfer Act. Transfer of the shares of Common Stock of Sony Corporation is effected exclusively through entry in the records maintained by JASDEC and the account management institutions, and title to the shares passes to the transferee at the time when the transfer of the shares is recorded at the transferee’s account at an account management institution. The holder of an account at an account management institution is presumed to be the legal holder of the shares recorded in such account.

Under the Companies Act and the Book-entry Transfer Act, in order to assert shareholders’ rights against Sony Corporation, a shareholder of shares must have its name and address registered in Sony Corporation’s register of shareholders. Under the central book-entry transfer system operated by JASDEC, shareholders shall notify the relevant account management institutions of certain information prescribed under the Book-entry Transfer Act or Sony Corporation’s Share Handling Regulations, including their names and addresses, and the registration on Sony Corporation’s register of shareholders is updated upon receipt by Sony Corporation of necessary information from JASDEC (as described in “

(Record date)

”). On the other hand, in order to assert, against Sony Corporation, shareholders’ rights to which shareholders are entitled, regardless of whether such shareholder held shares on the requisite record date, such as minority shareholders’ rights, including the right to propose a matter to be considered at a General Meeting of Shareholders, except for shareholders’ rights to request that Sony Corporation purchase or sell shares constituting less than a full unit (as described in “

(Unit share system)

”), JASDEC shall, upon the shareholder’s request, issue a notice of certain information, including the name and address of such shareholder, to Sony Corporation.

Table of Contents

Thereafter, such shareholder is required to present Sony Corporation a receipt of the notice request in accordance with the Sony Corporation’s Share Handling Regulations. Under the Book-entry Transfer Act, the shareholder shall exercise such shareholders’ right within four weeks after the notice above has been given to Sony Corporation.

Mitsubishi UFJ Trust and Banking Corporation is the transfer agent for Sony Corporation’s capital stock. As such, it keeps Sony Corporation’s register of shareholders in its office at

4-5,

Marunouchi

1-chome,

Chiyoda-ku,

Tokyo.

Non-resident

shareholders are required to appoint a standing proxy in Japan or file notice of a mailing address in Japan. Notices from Sony Corporation to

non-resident

shareholders are delivered to such standing proxies or mailing address. Japanese securities companies and commercial banks customarily act as standing proxies and provide related services for standard fees. The recorded holder of deposited shares underlying the American Depositary Shares (“ADSs”) is the depositary for the ADSs. Accordingly, holders of ADSs will not be able to directly assert shareholders’ rights against Sony Corporation.

(Authorized capital)

Under the Articles of Incorporation of Sony Corporation, Sony Corporation may only issue shares of Common Stock. Sony Corporation’s Articles of Incorporation provide that the total number of shares authorized to be issued by Sony Corporation is 3.6 billion shares.

All shares of capital stock of Sony Corporation have no par value. All issued shares are fully-paid and

non-assessable.

(Distribution of Surplus)

Distribution of Surplus — General

Under the Companies Act, distributions of cash or other assets by joint stock corporations to their shareholders, so called “dividends,” are referred to as “distributions of Surplus” (“Surplus” is defined in “— Restriction on distribution of Surplus”). Sony Corporation may make distributions of Surplus to shareholders any number of times per business year, subject to certain limitations described in “— Restriction on distribution of Surplus.” Distributions of Surplus are required in principle to be authorized by a resolution of a General Meeting of Shareholders, but Sony Corporation may authorize distributions of Surplus by a resolution of the Board of Directors as long as its

non-consolidated

annual financial statements and certain documents for the last business year present fairly its assets and profit or loss, as required by ordinances of the Ministry of Justice.

Distributions of Surplus may be made in cash or in kind in proportion to the number of shares of Common Stock held by each shareholder. A resolution of the Board of Directors or a General Meeting of Shareholders authorizing a distribution of Surplus must specify the kind and aggregate book value of the assets to be distributed, the manner of allocation of such assets to shareholders, and the effective date of the distribution. If a distribution of Surplus is to be made in kind, Sony Corporation may, pursuant to a resolution of the Board of Directors or (as the case may be) a General Meeting of Shareholders, grant a right to the shareholders to require Sony Corporation to make such distribution in cash instead of in kind. If no such right is granted to shareholders, the relevant distribution of Surplus must be approved by a special resolution of a General Meeting of Shareholders (refer to “

(Voting rights)

” with respect to a “special resolution”).

Under the Articles of Incorporation of Sony Corporation,

year-end

dividends and interim dividends may be distributed in cash to shareholders appearing in Sony Corporation’s register of shareholders as of March 31 and September 30 each year, respectively, in proportion to the number of shares of Common Stock held by each shareholder following approval by the Board of Directors or (as the case may be) the General Meeting of Shareholders. Sony Corporation is not obliged to pay any dividends in cash unclaimed for a period of five years after the date on which they first became payable.

In Japan, the

ex-dividend

date and the record date for dividends precede the date of determination of the amount of the dividends to be paid. The price of the shares of Common Stock generally goes

ex-dividend

on the business day immediately prior to the record date (or if the record date is not a business day, the second business day prior thereto).

Distribution of Surplus — Restriction on distribution of Surplus

In making a distribution of Surplus, Sony Corporation must, until the sum of its additional

paid-in

capital and legal reserve reaches one quarter of its stated capital, set aside in its additional

paid-in

capital and/or legal reserve an amount equal to

one-tenth

of the amount of Surplus so distributed.

The amount of Surplus at any given time must be calculated in accordance with the following formula:

A + B + C + D - (E + F + G)

In the above formula:

“A” =						the total amount of other capital surplus and other retained earnings, each such amount being that appearing on the non-consolidated balance sheet as of the end of the last business year
“B” =						(if Sony Corporation has disposed of its treasury stock after the end of the last business year) the amount of the consideration for such treasury stock received by Sony Corporation less the book value thereof
“C” =						(if Sony Corporation has reduced its stated capital after the end of the last business year) the amount of such reduction less the portion thereof that has been transferred to additional paid-in capital or legal reserve (if any)
“D” =						(if Sony Corporation has reduced its additional paid-in capital or legal reserve after the end of the last business year) the amount of such reduction less the portion thereof that has been transferred to stated capital (if any)
“E” =						(if Sony Corporation has cancelled its treasury stock after the end of the last business year) the book value of such treasury stock
“F” =						(if Sony Corporation has distributed Surplus to its shareholders after the end of the last business year) the total book value of the Surplus so distributed
“G” =						certain other amounts set forth in ordinances of the Ministry of Justice, including (if Sony Corporation has reduced Surplus and increased its stated capital, additional paid-in capital or legal reserve after the end of the last business year) the amount of such reduction and (if Sony Corporation has distributed Surplus to the shareholders after the end of the last business year) the amount set aside in additional paid-in capital or legal reserve (if any) as required by ordinances of the Ministry of Justice.

 

The aggregate book value of Surplus distributed by Sony Corporation may not exceed a prescribed distributable amount (the “Distributable Amount”), as calculated on the effective date of such distribution. The Distributable Amount at any given time shall be equal to the amount of Surplus less the aggregate of the following:

(a)

the book value of its treasury stock;

 

(b)

the amount of consideration for any of treasury stock disposed of by Sony Corporation after the end of the last business year; and

 

(c)

certain other amounts set forth in ordinances of the Ministry of Justice, including (if the sum of one-half of goodwill and the deferred assets exceeds the total of stated capital, additional paid-in capital and legal reserve, each such amount being that appearing on the non-consolidated balance sheet as of the end of the last business year) all or certain part of such exceeding amount as calculated in accordance with ordinances of the Ministry of Justice.

 

As Sony Corporation has become a company with respect to which consolidated balance sheets should also be considered in the calculation of the Distributable Amount (

renketsu haito kisei tekiyo kaisha

), Sony Corporation must further deduct from the amount of Surplus the excess amount, if any, of (x) the total amount of stockholders’ equity appearing on the

non-consolidated

balance sheet as of the end of the last business year and certain other amounts set forth by an ordinance of the Ministry of Justice over (y) the total amount of stockholders’ equity and certain other amounts set forth by an ordinance of the Ministry of Justice appearing on the consolidated balance sheet as of the end of the last business year.

If Sony Corporation has prepared interim financial statements as described below, and if such interim financial statements have been approved by the Board of Directors or (if so required by the Companies Act) by a

General Meeting of Shareholders, then the Distributable Amount must be adjusted to take into account the amount of profit or loss, and the amount of consideration for any of the treasury stock disposed of by Sony Corporation, during the period in respect of which such interim financial statements have been prepared. Sony Corporation may prepare

non-consolidated

interim financial statements consisting of a balance sheet as of any date subsequent to the end of the last business year and an income statement for the period from the first day of the current business year to the date of such balance sheet. Interim financial statements so prepared by Sony Corporation must be audited by the Audit Committee and the independent auditor, as required by the Companies Act and in accordance with the details prescribed by ordinances of the Ministry of Justice.

(Capital and reserves)

Sony Corporation may generally reduce its additional

paid-in

capital or legal reserve by resolution of a General Meeting of Shareholders and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as stated capital. On the other hand, Sony Corporation may generally reduce its stated capital by a special shareholders’ resolution (as defined in “

(Voting rights)

”) and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as additional

paid-in

capital. In addition, Sony Corporation may reduce its Surplus and increase either (i) stated capital or (ii) additional

paid-in

capital and/or legal reserve by the same amount, in either case by resolution of a General Meeting of Shareholders.

(Stock splits)

Sony Corporation may at any time split shares in issue into a greater number of shares at the determination of the CEO, and may amend its Articles of Incorporation to increase the number of the authorized shares to be issued to allow such stock split pursuant to a resolution of the Board of Directors or a determination by a Corporate Executive Officer to whom the authority to make such determination has been delegated by a resolution of the Board of Directors, rather than relying on a special shareholders’ resolution, which is otherwise required for amending the Articles of Incorporation.

When a stock split is to be made, Sony Corporation must give public notice of the stock split, specifying the record date thereof, at least two weeks prior to such record date. Under the central book-entry transfer system operated by JASDEC, Sony Corporation must also give notice to JASDEC regarding a stock split at least two weeks prior to the relevant effective date of the stock split. On the effective date of the stock split, the numbers of shares recorded in all accounts held by Sony Corporation’s shareholders at account managing institutions or JASDEC will be increased in accordance with the applicable ratio.

(Consolidation of shares)

Sony Corporation may at any time consolidate issued shares into a smaller number of shares by a special shareholders’ resolution. When a consolidation of shares is to be made, Sony Corporation must give public notice or notice to each shareholder at least two weeks prior to the effective date of the consolidation of shares. Under the central book-entry transfer system operated by JASDEC, Sony Corporation must also give notice to JASDEC regarding a consolidation of shares at least two weeks prior to the effective date of the consolidation of shares. On the effective date of the consolidation of shares, the numbers of shares recorded in all accounts held by Sony Corporation’s shareholders at account managing institutions or JASDEC will be decreased in accordance with the applicable ratio. Sony Corporation must disclose the reason for the consolidation of shares at a General Meeting of Shareholders.

(General Meeting of Shareholders)

The Ordinary General Meeting of Shareholders of Sony Corporation for each business year is normally held in June of each year in Tokyo, Japan. In addition, Sony Corporation may hold an Extraordinary General Meeting of Shareholders whenever necessary by giving notice thereof at least two weeks prior to the date set for the meeting.

Notice of a shareholders’ meeting setting forth the place, time and purpose thereof must be mailed to each shareholder having voting rights (or, in the case of a

non-resident

shareholder, to such shareholder’s resident proxy or mailing address in Japan) at least two weeks prior to the date set for the meeting. Under the Companies Act, such notice may be given to shareholders by electronic means, subject to obtaining consent by the relevant shareholders. The record date for an Ordinary General Meeting of Shareholders is March 31 of each year.

Table of Contents

Any shareholder or group of shareholders holding at least 3% of the total number of voting rights for a period of six months or more may require the convocation of a General Meeting of Shareholders for a particular purpose. Unless such a shareholders’ meeting is convened promptly or a convocation notice of a meeting which is to be held not later than eight weeks from the day of such demand is dispatched, the requiring shareholder may, upon obtaining a court approval, convene such a shareholders’ meeting.

Any shareholder or group of shareholders holding at least 300 voting rights or 1% of the total number of voting rights for a period of six months or more may propose a matter to be considered at a General Meeting of Shareholders by submitting a written request to Sony Corporation at least eight weeks prior to the date set for such meeting.

If the Articles of Incorporation so provide, any of the minimum voting rights or percentages, time periods and number of voting rights necessary for exercising the minority shareholder rights described above may be decreased or shortened. Sony Corporation’s Articles of Incorporation currently do not include any such provisions.

(Voting rights)

So long as Sony Corporation maintains the unit share system, a holder of shares constituting one or more units is entitled to one vote for each such unit of stock (refer to “

(Unit share system)

” below; currently 100 shares constitute one unit), except that no voting rights with respect to shares of capital stock of Sony Corporation are afforded to Sony Corporation or any corporate or certain other entities more than

one-quarter

of the total voting rights of which are directly or indirectly held by Sony Corporation. If Sony Corporation eliminates from its Articles of Incorporation the provisions relating to units of stock, holders of capital stock will have one vote for each share they hold. Except as otherwise provided by law or by the Articles of Incorporation of Sony Corporation, a resolution can be adopted at a General Meeting of Shareholders by a majority of the number of voting rights of all the shareholders represented at the meeting. The Companies Act and Sony Corporation’s Articles of Incorporation provide, however, that the quorum for the election of Directors shall be

one-third

of the total number of voting rights of all the shareholders. Sony Corporation’s shareholders are not entitled to cumulative voting in the election of Directors. Shareholders may cast their votes in writing and may also exercise their voting rights through proxies, provided that the proxies are also shareholders holding voting rights. Shareholders may also exercise their voting rights by electronic means pursuant to the method designated by Sony Corporation.

The Companies Act and the Articles of Incorporation of Sony Corporation provide that in order to amend the Articles of Incorporation and in certain other instances, including:

(1)

acquisition of its own shares from a specific party other than its subsidiaries;

 

(2)

consolidation of shares;

 

(3)

any offering of new shares or existing shares held by Sony Corporation as treasury stock at a “specially favorable” price (or any offering of stock acquisition rights to acquire shares of capital stock, or bonds with stock acquisition rights on “specially favorable” conditions) to any persons other than shareholders;

 

(4)

the exemption of liability of a Director, Corporate Executive Officer or independent auditor with certain exceptions;

 

(5)

a reduction of stated capital with certain exceptions;

 

(6)

a distribution of in-kind dividends which meets certain requirements;

 

(7)

dissolution, merger, consolidation, or corporate split with certain exceptions;

 

(8)

the transfer of the whole or a material part of the business;

 

(9)

the transfer of the whole or a part of the shares or equity interests in a subsidiary which meets certain requirements;

 

(10)

the taking over of the whole of the business of any other corporation with certain exceptions; or

 

(11)

share exchange or share transfer for the purpose of establishing 100% parent-subsidiary relationships with certain exceptions,

Table of Contents 

the quorum shall be

one-third

of the total number of voting rights of all the shareholders, and the approval by at least

two-thirds

of the number of voting rights of all the shareholders represented at the meeting is required (the “special shareholders’ resolutions”).

(Issue of additional shares and

pre-emptive

rights)

Holders of Sony Corporation’s shares of capital stock have no

pre-emptive

rights under its Articles of Incorporation. Authorized but unissued shares may be issued, or existing shares held by Sony Corporation as treasury stock may be transferred, at such times and upon such terms as the Board of Directors or the CEO determines, subject to the limitations as to the offering of new shares or transfer of existing shares held by Sony Corporation as treasury stock at a “specially favorable” price mentioned under “

(Voting rights)

” above.

In the case of an issuance of shares (including a transfer of existing shares held by Sony Corporation as treasury stock) or stock acquisition rights whereby any subscriber will hold more than 50% of the voting rights of all shareholders, generally Sony Corporation shall give public notice at least two weeks prior to the payment date for such issuance, and if shareholders who hold

one-tenth

or more of the voting rights of all shareholders dissent from the issuance of shares or stock acquisition rights, the approval by a resolution of a General Meeting of Shareholders is generally required before the payment date pursuant to the Companies Act. In addition, in the case of an issuance of shares (including a transfer of existing shares held by Sony Corporation as treasury stock) or stock acquisition rights by way of an allotment to a third party which would dilute the outstanding voting shares by 25% or more or change the controlling shareholder, in addition to a resolution of the Board of Directors, the approval of the shareholders or an affirmative vote from a person independent of the management is generally required pursuant to the rules of the TSE. The Board of Directors or the CEO may, however, determine that shareholders shall be given subscription rights regarding a particular issue of new shares, in which case such rights must be given on uniform terms to all shareholders as of a record date of which not less than two weeks’ prior public notice is given. Each of the shareholders to whom such rights are given must also be given notice of the expiry thereof at least two weeks prior to the date on which such rights expire.

Subject to certain conditions, Sony Corporation may issue stock acquisition rights by a resolution of the Board of Directors or a determination by the CEO. Holders of stock acquisition rights may exercise their rights to acquire a certain number of shares within the exercise period as prescribed in the terms of their stock acquisition rights. Upon exercise of stock acquisition rights, Sony Corporation will be obliged to issue the relevant number of new shares or alternatively to transfer the necessary number of treasury stock held by it.

In cases where a particular issue of new shares or stock acquisition rights (i) violates laws and regulations or Sony Corporation’s Articles of Incorporation, or (ii) will be performed in a materially unfair manner, and shareholders may suffer disadvantages therefrom, such shareholders may file an injunction to enjoin such issue with a court.

(Liquidation rights)

In the event of a liquidation of Sony Corporation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed among the holders of shares of Common Stock in proportion to the respective numbers of shares of Common Stock held.

(Record date)

March 31 is the record date for Sony Corporation’s

year-end

dividends, if declared. So long as Sony Corporation maintains the unit share system, shareholders who are registered as the holders of one or more unit of stock in Sony Corporation’s register of shareholders at the end of each March 31 are also entitled to exercise shareholders’ rights at the Ordinary General Meeting of Shareholders with respect to the business year ending on such March 31. September 30 is the record date for interim dividends, if declared. In addition, Sony Corporation may set a record date for determining the shareholders entitled to other rights and for other purposes by giving at least two weeks’ prior public notice.

JASDEC is required to promptly give Sony Corporation notice of the names and addresses of Sony Corporation’s shareholders, the numbers of shares of Common Stock held by them and other relevant information as of such respective record dates.

The price of shares generally goes

ex-dividends

or

ex-rights

on Japanese stock exchanges on the business day immediately prior to a record date (or if the record date is not a business day, the second business day prior thereto), for the purpose of dividends or rights offerings.

(Acquisition by Sony Corporation of its capital stock)

Under the Companies Act and the Articles of Incorporation of Sony Corporation, Sony Corporation may acquire shares of Common Stock (i) from a specific shareholder other than any of its subsidiaries (pursuant to the special shareholders’ resolution), (ii) from any of its subsidiaries (pursuant to a determination by the CEO as delegated by the Board of Directors), or (iii) by way of purchase on any Japanese stock exchange on which Sony Corporation’s shares of Common Stock are listed or by way of tender offer (pursuant to a resolution of the Board of Directors, as long as its

non-consolidated

annual financial statements and certain documents for the last business year present fairly its assets and profit or loss, as required by ordinances of the Ministry of Justice).

In the case of (i) above, any other shareholder may make a request to Sony Corporation that such other shareholder be included as a seller in the proposed purchase, provided that no such right will be available if the purchase price or any other consideration to be received by the relevant specific shareholder will not exceed the last trading price of the shares on the relevant stock exchange on the day immediately preceding the date on which the resolution mentioned in (i) above was adopted (or, if there is no trading in the shares on the stock exchange or if the stock exchange is not open on such day, the price at which the shares are first traded on such stock exchange thereafter).

The total amount of the purchase price of shares of Common Stock may not exceed the Distributable Amount, as described in “(

Distribution of Surplus

) — Distributions of Surplus — Restriction on distribution of Surplus.”

Shares acquired by Sony Corporation may be held for any period or may be retired at the determination of the CEO. Sony Corporation may also transfer (by public or private sale or otherwise) to any person the treasury stock held by it, subject to a determination by the CEO, and subject also to other requirements similar to those applicable to the issuance of new shares, as described in “

(Issue of additional shares and pre-emptive rights)

” above. Sony Corporation may also utilize its treasury stock for the purpose of transfer to any person upon exercise of stock acquisition rights or for the purpose of acquiring another company by way of merger, share exchange or corporate split through exchange of treasury stock for shares or assets of the acquired company. 

(Unit share system)

The Articles of Incorporation of Sony Corporation provide that 100 shares constitute one “unit” of shares of stock. The Board of Directors or the Corporate Executive Officer to whom the authority to make such a determination has been delegated by a resolution of the Board of Directors is permitted to amend the Articles of Incorporation to reduce the number of shares that constitute a unit or to abolish the unit share system entirely. Under the Companies Act, the number of shares constituting one unit cannot exceed 1,000 shares nor 0.5% of the total number of issued shares.

Under the unit share system, shareholders have one voting right for each unit of stock that they hold. Any number of shares less than one full unit have neither voting rights nor rights related to voting rights. Holders of shares constituting less than one unit will have no other shareholder rights if Sony Corporation’s Articles of Incorporation so provide, except that such holders may not be deprived of certain rights specified in the Companies Act or an ordinance of the Ministry of Justice, including the right to receive distribution of Surplus.

A holder of shares constituting less than one full unit may require Sony Corporation to purchase such shares at their market value in accordance with the provisions of the Share Handling Regulations of Sony Corporation. In addition, the Articles of Incorporation of Sony Corporation provide that a holder of shares constituting less than one full unit may request Sony Corporation to sell to such holder such amount of shares which will, when added together with the shares constituting less than one full unit, constitute one full unit of stock. Such request by a holder and the sale by Sony Corporation must be made in accordance with the provisions of the Share Handling Regulations of Sony Corporation. As prescribed in the Share Handling Regulations, such requests shall be made through an account management institution and JASDEC pursuant to the rules set by JASDEC, without going through the notification procedure required for the exercise of the shareholders’ rights to which shareholders are entitled, regardless of whether such shareholder held shares on the requisite record date, as described in “

(General)

.” Shares constituting less than a full unit are transferable, under the central book-entry transfer system described in “

(General)

.” Under the rules of the Japanese stock exchanges, however, shares constituting less than a full unit do not comprise a trading unit, except in limited circumstances, and accordingly may not be sold on the Japanese stock exchanges.

(Sale by Sony Corporation of shares held by shareholders whose location is unknown)

Sony Corporation is not required to send a notice to a shareholder if a notice to such shareholder fails to arrive at the registered address of the shareholder in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation continuously for five years or more.

In addition, Sony Corporation may sell or otherwise dispose of shares of capital stock for which the location of the shareholder is unknown. Generally, if (i) notices to a shareholder fail to arrive continuously for five years or more at the shareholder’s registered address in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation, and (ii) the shareholder fails to receive distributions of Surplus on the shares continuously for five years or more at the address registered in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation, Sony Corporation may sell or otherwise dispose of such shareholder’s shares at the then market price of the shares by a determination of a Corporate Executive Officer and after giving at least three months’ prior public and individual notice, and hold or deposit the proceeds of such sale or disposal of shares for such shareholder.

Reporting of substantial shareholdings

The Financial Instruments and Exchange Act of Japan and its related regulations require any person, regardless of residence, who has become, beneficially and solely or jointly, a holder of more than 5% of the total issued shares of capital stock of a company listed on any Japanese stock exchange or whose shares are traded on the

over-the-counter

market in Japan to file with the Director General of the competent Local Finance Bureau of the Ministry of Finance within five business days a report concerning such shareholdings. A similar report must also be filed in respect of any subsequent change of 1% or more in any such holding, or any change in material matters set out in reports previously filed, with certain exceptions. For this purpose, shares issuable to such persons upon conversion of convertible securities or exercise of share subscription warrants or stock acquisition rights are taken into account in determining both the number of shares held by such holders and the issuer’s total issued share capital. Any such report shall be filed with the Director General of the relevant Local Finance Bureau of the Ministry of Finance through the Electronic Disclosure for Investors’ Network (EDINET) system.

Ownership restrictions

Except for the general limitation under Japanese anti-trust and anti-monopoly regulations against holding of shares of capital stock of a Japanese corporation which leads or may lead to a restraint of trade or monopoly, except for the limitations under the Foreign Exchange Regulations as described in “D. Exchange Controls” below, and except for general limitations under the Companies Act or Sony Corporation’s Articles of Incorporation on the rights of shareholders applicable regardless of residence or nationality, there is no limitation under Japanese laws and regulations applicable to Sony Corporation or under its Articles of Incorporation on the rights of

non-residents

or foreign shareholders to hold or exercise voting rights on the shares of capital stock of Sony Corporation.

There is no provision in Sony Corporation’s Articles of Incorporation or internal regulations that would have an effect of delaying, deferring or preventing a change in control of Sony Corporation and that would operate only with respect to a merger, acquisition or corporate restructuring involving Sony Corporation.

Japanese Foreign Exchange Controls Regulations

The following is a general summary of major Japanese foreign exchange controls regulations applicable to holders of shares of capital stock or voting rights of Sony Corporation

or holders of ADSs

who are “exchange

non-residents”

or “foreign investors,” as described below. The statements regarding Japanese foreign exchange control regulations set forth below are based on the laws and regulations in force and as interpreted by the Japanese authorities as of the date of this annual report and are subject to subsequent changes in the applicable Japanese laws or interpretations thereof. This summary is not exhaustive of all possible foreign exchange controls considerations that may apply to a particular investor, and potential investors are advised to satisfy themselves as to the overall foreign exchange controls consequences of the acquisition, ownership and disposition of shares of capital stock or voting rights of Sony Corporation

or ADSs

by consulting their own advisors.

The Foreign Exchange and Foreign Trade Act of Japan (the “FEFTA”) and its related cabinet orders and ministerial ordinances (collectively, the “Foreign Exchange Regulations”) govern certain aspects relating to the

97

---

Table of Contents

acquisition and holding of shares of capital stock and voting rights of Sony Corporation by “exchange

non-residents”

and by “foreign investors” (as these terms are defined below). The Foreign Exchange Regulations also apply to the acquisition and holding of ADSs and the exercise of voting rights by holders of ADSs who are “foreign investors” that constitute an “inward direct investment” (as defined below).

Capital Transaction

Except as described below with respect to an “inward direct investment” by a “foreign investor”, the Foreign Exchange Regulations currently in effect do not affect transactions between exchange

non-residents

to purchase or sell shares of a Japanese listed corporation outside Japan using currencies other than Japanese yen.

In general, the acquisition of shares of a Japanese corporation (such as the shares of capital stock of Sony Corporation) by an exchange

non-resident

from an exchange resident requires post facto reporting by the exchange resident to the Minister of Finance. No such reporting requirement is imposed, however, if:

(i)

the aggregate purchase price of the relevant shares is 100 million yen or less;

 

(ii)

the acquisition is effected through any bank, financial instruments business operator or other entity prescribed by the Foreign Exchange Regulations acting as an agent or intermediary; or

 

(iii)

the acquisition constitutes an “inward direct investment” described below (in which case a prior notification requirement may apply).

 

Exchange residents are defined in the Foreign Exchange Regulations as:

(i)

individuals who reside within Japan; or

 

(ii)

corporations whose principal offices are located within Japan.

 

Exchange

non-residents

are defined in the Foreign Exchange Regulations as:

(i)

individuals who do not reside in Japan; or

 

(ii)

corporations whose principal offices are located outside Japan.

 

Generally, branches and other offices of

non-resident

corporations that are located within Japan are regarded as exchange residents. Conversely, branches and other offices of Japanese corporations located outside Japan are regarded as exchange

non-residents.

Inward Direct Investment in Shares of Listed Corporations

On May 8, 2020, an amendment to the Foreign Exchange Regulations (the “Amendment”) came into effect. By the full implementation of the Amendment on June 7, 2020 (the “Implementation of the Amendment”), the requirements and procedures regarding the prior notifications of inward direct investment to the Minister of Finance and any other competent Ministers under the FEFTA were amended, as described below.

Definition of Foreign Investor

Foreign investors are defined in the Foreign Exchange Regulations as:

(i)

individuals who are exchange non-residents;

 

(ii)

corporations or other entities that are organized under the laws of foreign countries or whose principal offices are located outside Japan;

 

(iii)

corporations of which 50% or more of the total voting rights are held, directly or indirectly, by individuals and/or corporations falling within (i) and/or (ii) above;

 

(iv)

partnerships under the Civil Code of Japan established to invest in corporations, limited partnerships for investment under the Limited Partnership Act for Investment of Japan or any other similar partnerships under foreign law of which (a) 50% or more of the total contributions are made by individuals and/or corporations falling within (i), (ii), (iii) above and/or (v) below or any other persons prescribed under the Foreign Exchange Regulations or (b) a majority of the general partners are individuals and/or corporations falling within (i), (ii), (iii) above and/or (v) below or any other persons prescribed under the Foreign Exchange Regulations; or

 

(v)

corporations or other entities, a majority of whose directors or other officers (or directors or other officers having the power of representation) are individuals who are exchange non-residents.

Table of Contents

Definition of Inward Direct Investment

Prior to the Implementation of the Amendment, if a foreign investor acquired shares or voting rights of a Japanese corporation that is listed on a Japanese stock exchange (such as the shares of capital stock of Sony Corporation) or that is traded on an

over-the-counter

market in Japan and, as a result of the acquisition, the foreign investor, in combination with any existing holdings, directly or indirectly held 10% or more of the total number of issued shares or the total number of voting rights of the relevant corporation, such acquisition constituted an “inward direct investment.” By the Implementation of the Amendment, the threshold for the acquisition of shares or voting rights that constitutes an “inward direct investment” was lowered from 10% to 1%. In addition, the acquisition of the authority to exercise, either directly or through instructions, voting rights held by other shareholders that results in the foreign investor, in combination with any existing shareholding, directly or indirectly holding 1% or more of the total number of voting rights of the relevant corporation constitutes an “inward direct investment.”

In addition to the acquisitions of shares or voting rights described above, prior to the Implementation of the Amendment, if a foreign investor (i) was granted the authority to exercise voting rights on behalf of other shareholders of the relevant corporation regarding certain matters controlling or having a material influence on the management of such corporation, such as the election or removal of directors, or (ii) obtained consent from another foreign investor holding the voting rights of the relevant corporation to exercise the voting rights of such corporation held by such other foreign investor jointly, and, in each case, as a result of these arrangements, the number of the voting rights directly or indirectly held by the foreign investor, including the total number of the voting rights subject to such proxy, or the sum of the number of the voting rights directly or indirectly held by the foreign investor and such other foreign investor subject to such joint voting agreement, as the case may be, was 10% or more of the total number of voting rights of the relevant corporation, each such arrangement regarding voting rights (hereinafter referred to as a “voting arrangement”) also constituted an “inward direct investment,” and still constitutes an “inward direct investment” after the Implementation of the Amendment.

Additionally, after the Implementation of the Amendment, if a foreign investor directly or indirectly holds 1% or more of the total voting rights of a Japanese listed corporation and, at a general meeting of shareholders, consents to certain proposals having a material influence on the management of such corporation such as the (i) election of such foreign investor or any of its related persons (as defined in the Foreign Exchange Regulations) as a director or corporate auditor of the relevant corporation or (ii) transfer or discontinuation of its business, such consent also constitutes an “inward direct investment.”

Prior Notification Requirements regarding Inward Direct Investment

Prior to the Implementation of the Amendment, if a foreign investor intended to consummate an acquisition of shares or voting rights of a Japanese listed corporation that constituted an “inward direct investment” as described above, unless certain exemptions applied (such as where the foreign investor is in a country that is listed on an exemption schedule in the Foreign Exchange Regulations and where that Japanese corporation is not engaged in certain businesses (the “Designated Businesses”) designated by the Foreign Exchange Regulations), a prior notification of the relevant inward direct investment was required to be filed with the Minister of Finance and any other competent Ministers. After the Implementation of the Amendment, such prior notification is still required in such circumstances as described above but the definition of “inward direct investment” is expanded as described in “Definition of Inward Direct Investment.”

However, after the Implementation of the Amendment, if a foreign investor is seeking to acquire shares or voting rights of a Japanese listed corporation or the authority to exercise, either directly or through instructions, voting rights held by other shareholders and such acquisition would constitute an “inward direct investment”, such foreign investor may be eligible for the newly introduced exemptions if certain conditions are met. In the case of an acquisition of shares or voting rights or the authority to exercise, either directly or through instructions, voting rights of a Japanese listed corporation that is engaged in a Designated Business other than certain Designated Business designated by the Foreign Exchange Regulations as a core sector business (the “Core Sector Designated Businesses”), the foreign investor may be exempted from the prior notification requirement if such foreign investor complies with the following conditions (the “Exemption Conditions”):

(i)

the foreign investor or its related persons will not become directors or corporate auditors of the relevant corporation;

 

 

(ii)

the foreign investor will not make certain proposals (as prescribed in the Foreign Exchange Regulations) at the general meeting of shareholders, including transfer or discontinuation of the Designated Businesses of the relevant corporation; and

 

 

99

---

Table of Contents 

(iii)

the foreign investor will not access non-public technical information in relation to the Designated Businesses of the relevant corporation, or take certain other actions that may lead to the leak of such non-public technical information (as prescribed in the Foreign Exchange Regulations).

 

 

In addition, in the case of an acquisition of shares or voting rights or the authority to exercise, directly or through instructions, voting rights of a Japanese listed corporation that is engaged in the Core Sector Designated Businesses, the foreign investor may be exempted from the prior notification requirement, if, as a result of such acquisition, the foreign investor, in combination with any existing holdings, directly or indirectly holds less than 10% of the total number of issued shares or voting rights of the relevant corporation and such foreign investor complies with the Exemption Conditions and the following additional conditions:

(i)

the foreign investor will not attend, or not cause any persons designated by it to attend, meetings of the relevant corporation’s board of directors, or meetings of committees having authority to make important decisions, in respect of the Core Sector Designated Businesses of the relevant corporation; and

 

 

(ii)

the foreign investor will not make, or not cause any persons designated by it to make, proposals to such board or committees or their members in writing or electronic form requesting any response or actions by certain deadlines in respect of the Core Sector Designated Businesses of the relevant corporation.

 

 

Notwithstanding the above, if a foreign investor falls under a category of disqualified investors designated by the Foreign Exchange Regulations (including (a) investors who have records of certain sanctions due to violations of the FEFTA and (b) certain investors that are state-owned enterprises or other related entities that are not otherwise accredited by the Minister of Finance), in no event may such foreign investor be eligible for the exemptions described above. On the other hand, if a foreign investor, excluding the disqualified investors described in the foregoing sentence, falls under a category of certain foreign financial institutions (as prescribed in the Foreign Exchange Regulations) and complies with the Exemption Conditions, such foreign investor may be eligible for the exemptions described above, even if the acquisition results in such foreign investor’s directly or indirectly holding 10% or more of the total number of issued shares or voting rights of the corporation engaged in the Core Sector Designated Businesses, which would have required prior notification before the Implementation of the Amendment.

For reference purposes only, the Minister of Finance publishes, and may update from time to time, a list that classifies Japanese listed corporations into the following categories: (i) corporations engaged only in businesses other than the Designated Businesses, (ii) corporations engaged in Designated Businesses other than Core Sector Designated Businesses and (iii) corporations engaged in the Core Sector Designated Businesses. According to the list published by the Minister of Finance as of May 8, 2020, Sony Corporation is classified as category (iii) above.

In addition, if a foreign investor intends to make a voting arrangement with respect to a Japanese listed corporation engaged in the Designated Businesses or, after the Implementation of the Amendment, consents to a proposal at the general meeting of shareholders of such corporation, in each case, that constitutes an “inward direct investment” as described in “Definition of Inward Direct Investment” above, in certain circumstances, prior notification of the relevant inward direct investment must be filed with the Minister of Finance and any other competent Ministers. In such cases, the newly introduced exemptions from the prior notification requirements may not be available, except for cases where the relevant voting arrangement is a joint voting agreement with other foreign investors to exercise voting rights regarding matters other than certain matters with respect to controlling or having a material influence on the management of the relevant corporation, such as the election or removal of directors, which would have required prior notification before the Implementation of the Amendment.

Acquisitions of shares by foreign investors by way of stock split are not subject to the foregoing notification requirements.

Procedures for Prior Notification regarding Inward Direct Investment

If such prior notification is filed, the proposed inward direct investment may not be consummated until 30 days after the date of filing during which time the Ministers will review the proposed inward direct investment, although this screening period may be shortened to two weeks by such Ministers if they no longer deem it necessary to review the proposed inward direct investment. The Ministers may extend the screening period up to five months if they deem it necessary to continue to review the proposed inward direct investment, may

100

Table of Contents

recommend any modification or abandonment of the proposed inward direct investment and, if the foreign investor does not accept such recommendation, the Ministers may order the modification or abandonment of such inward direct investment. In addition, if the Ministers consider the proposed inward direct investment to be an inward direct investment that is likely to cause damage to the national security of Japan, to interfere with the maintenance of public order or to pose an obstacle to the preservation of public safety, and, if a foreign investor (i) consummates such inward direct investment without filing the prior notification described above; (ii) consummates such inward direct investment before the expiration of the screening period described above; (iii) in connection with such inward direct investment, makes false statements in the prior notification described above; or (iv) does not follow the recommendation or order issued by the Ministers to modify or abandon such inward direct investment, the Ministers may order such foreign investor to divest all or part of the shares acquired or take other measures.

Post Facto Reporting Requirements regarding Inward Direct Investment

After the Implementation of the Amendment, a foreign investor who consummates an inward direct investment as described above through an acquisition of shares or voting rights or the authority to exercise, directly or through instructions, voting rights of a Japanese listed corporation that is engaged in the Designated Businesses, but is not subject to the prior notification requirements described above due to the exemptions from such prior notification requirements, in general, must file a report of the relevant inward direct investment with the Minister of Finance and any other competent Ministers having jurisdiction over such Japanese corporation within 45 days of the date when, as a result of such acquisition, the foreign investor, in combination with any existing holdings, directly or indirectly holds (i) 1% or more but less than 3% of the total number of issued shares or voting rights, for the first time, (ii) 3% or more but less than 10% of the total number of issued shares or voting rights, for the first time, or (iii) 10% or more of the total number of issued shares or voting rights (excluding, in the cases of (i) and (ii) above, a foreign investor who falls under a category of certain foreign financial institutions (as prescribed in the Foreign Exchange Regulations)). In addition, if a foreign investor consummates the inward direct investment described above through the acquisition of shares or voting rights or the authority to exercise, directly or through instructions, voting rights of a Japanese listed corporation that is not engaged in the Designated Businesses (which is not subject to the prior notification requirements described above) and, as a result of such inward direct investment, such foreign investor, in combination with any existing holdings, directly or indirectly holds 10% or more of shares or voting rights of the total number of issued shares or voting rights of the relevant corporation, such foreign investor must file a report of the relevant inward direct investment with the Minister of Finance and any other competent Ministers having jurisdiction over such Japanese corporation within 45 days of such inward direct investment.

In addition, after the Implementation of the Amendment, if a foreign investor consummates the inward direct investment described above through a voting arrangement with respect to a Japanese listed corporation that is not engaged in the Designated Businesses (which is not subject to the prior notification requirements described above), such foreign investor must file a report of the relevant inward direct investment with the Minister of Finance and any other competent Ministers having jurisdiction over such Japanese corporation within 45 days of such inward direct investment.

Acquisitions of shares by foreign investors by way of stock split are not subject to the foregoing reporting requirements.

Dividends and Proceeds of Sale

Under the Foreign Exchange Regulations, dividends paid on and the proceeds from sales in Japan of shares of capital stock of Sony Corporation held by exchange

non-residents

may generally be converted into any foreign currency and repatriated abroad.

E.

Taxation

 

The following is a summary of the major Japanese national tax and U.S. federal income tax consequences of the ownership, acquisition and disposition of shares of Common Stock of Sony Corporation and of ADRs evidencing ADSs representing shares of Common Stock of Sony Corporation by a

non-resident

of Japan or a

non-Japanese

corporation without a permanent establishment in Japan. The summary does not purport to be a comprehensive description of all of the tax considerations that may be relevant to any particular investor, and does not take into account any specific individual circumstances of any particular investor. Accordingly, holders of shares of Common Stock or ADSs of Sony Corporation are encouraged to consult their tax advisors regarding the application of the considerations discussed below to their particular circumstances.

101

---

Table of Contents

This summary is based upon the representations of the depositary and the assumption that each obligation in the deposit agreement in relation to the ADSs dated as of October 15, 2014, and in any related agreement, will be performed in accordance with its terms.

For purposes of the income tax convention between Japan and the United States (the “Treaty”) and the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. holders of ADSs generally will be treated as owning shares of Common Stock of Sony Corporation underlying the ADSs evidenced by the ADRs. For the purposes of the following discussion, a “U.S. holder” is a holder that:

(i)

is a resident of the U.S. for purposes of the Treaty;

 

(ii)

does not maintain a permanent establishment in Japan (a) with which shares of Common Stock or ADSs of Sony Corporation are effectively connected and through which the U.S. holder carries on or has carried on business or (b) of which shares of Common Stock or ADSs of Sony Corporation form part of the business property; and

 

(iii)

is eligible for benefits under the Treaty with respect to income and gain derived in connection with shares of Common Stock or ADSs of Sony Corporation.

 

The following is a summary of the principal Japanese tax consequences (limited to national taxes) to

non-residents

of Japan or

non-Japanese

corporations without a permanent establishment in Japan

(“non-resident

Holders”) who are holders of shares of Common Stock of Sony Corporation or of ADRs evidencing ADSs representing shares of Common Stock of Sony Corporation. The information given below regarding Japanese taxation is based on the tax laws and tax treaties in force and their interpretations by the Japanese tax authorities as of June 26, 2020. Tax laws and tax treaties as well as their interpretations may change at any time, possibly with retroactive effect. Sony Corporation will not update this summary for any changes in the tax laws or tax treaties or their interpretation that occurs after such date.

Generally,

non-resident

Holders are subject to Japanese withholding tax on dividends paid by Japanese corporations. Such taxes are withheld prior to payment of dividends as required by Japanese law. Stock splits are, in general, not a taxable event.

In the absence of an applicable tax treaty, convention or agreement reducing the maximum rate of Japanese withholding tax or allowing exemption from Japanese withholding tax, the rate of Japanese withholding tax applicable to dividends paid by Japanese corporations to

non-resident

Holders is generally 20.42%, provided, with respect to dividends paid on listed shares issued by a Japanese corporation (such as the shares of Common Stock or ADSs of Sony Corporation) to

non-resident

Holders other than any individual shareholder who holds 3% or more of the total shares issued by the relevant Japanese corporation, the aforementioned 20.42% withholding tax rate is reduced to 15.315% for dividends due and payable on or before December 31, 2037. Due to the imposition of a special additional withholding tax (2.1 % of the original withholding tax amount) to secure funds for reconstruction from the Great East Japan Earthquake, the original withholding tax rates of 15% and 20% as applicable, have been effectively increased to 15.315% and 20.42%, respectively, until December 31, 2037. 

As of the date of this document, Japan has income tax treaties, conventions or agreements in force, whereby the above-mentioned withholding tax rate is reduced, in most cases to 15% or 10% for portfolio investors (15% under the income tax treaties with, among other countries, Canada, Denmark, Finland, Germany, Iceland, Ireland, Italy, Luxembourg, New Zealand, Norway, Singapore and Spain, and 10% under the income tax treaties with, among other countries, Australia, Austria, Belgium, France, Hong Kong, the Netherlands, Portugal, Sweden, Switzerland, the U.K. and the United States). Under the Treaty, the maximum rate of Japanese withholding tax that may be imposed on dividends paid by a Japanese corporation to a U.S. holder that does not own directly or indirectly at least 10% of the voting stock of the Japanese corporation is generally reduced to 10% of the gross amount actually distributed, and dividends paid by a Japanese corporation to a U.S. holder that is a pension fund are exempt from Japanese income taxation by way of withholding or otherwise unless such dividends are derived from the carrying on of a business, directly or indirectly, by such pension fund.

If the maximum tax rate provided for in the income tax treaty applicable to dividends paid by Sony Corporation to any particular

non-resident

Holder is lower than the withholding tax rate otherwise applicable under Japanese tax law, or if any particular

non-resident

Holder is exempt from Japanese income tax with respect to such dividends under the income tax treaty applicable to such particular

non-resident

Holder, such

non-resident

Holder who is entitled to a reduced rate of or exemption from Japanese withholding tax on payment of dividends on shares of Common Stock by Sony Corporation is, in principle, required to submit an Application Form for Income Tax Convention Regarding Relief from Japanese Income Tax and Special Income Tax for Reconstruction on Dividends (together with any other required forms and documents) in advance through the

102

---

Table of Contents

withholding agent to the relevant tax authority before the payment of dividends. A standing proxy for

non-resident

Holders of a Japanese corporation may provide this application service. In this regard, a certain simplified special filing procedure is available for

non-resident

Holders to claim treaty benefits of exemption from or reduction of Japanese withholding tax, by submitting a Special Application Form for Income Tax Convention Regarding Relief from Japanese Tax and Special Income Tax for Reconstruction on Dividends of Listed Stock (together with any other required forms and documents). With respect to ADSs, this reduced rate or exemption is applicable if the depositary or its agent submits two Application Forms (one before payment of dividends and the other within eight months after the record date concerning such payment of dividends). To claim this reduced rate or exemption, a

non-resident

Holder of ADSs will be required to file a proof of taxpayer status, residence and beneficial ownership (as applicable) and to provide other information or documents as may be required by the depositary. A

non-resident

Holder who is entitled, under an applicable income tax treaty, to a reduced rate which is lower than the withholding tax rate otherwise applicable under Japanese tax law or an exemption from the withholding tax, but failed to submit the required application in advance will be entitled to claim the refund of taxes withheld in excess of the rate under an applicable tax treaty (if such

non-resident

Holder is entitled to a reduced treaty rate under the applicable income tax treaty) or the full amount of tax withheld (if such

non-resident

Holder is entitled to an exemption under the applicable income tax treaty) from the relevant Japanese tax authority, by complying with a certain subsequent filing procedure. Sony Corporation does not assume any responsibility to ensure withholding at the reduced treaty rate or to ensure the absence of withholding for shareholders who would be so eligible under any applicable income tax treaty but where the required procedures as stated above are not followed.

Gains derived from the sale of shares of Common Stock or ADSs of Sony Corporation outside Japan by a

non-resident

Holder holding such shares or ADSs as portfolio investors are, in general, not subject to Japanese income tax or corporation tax under Japanese tax law. U.S. holders are not subject to Japanese income or corporation tax with respect to such gains under the Treaty.

Japanese inheritance tax and gift tax at progressive rates may be payable by an individual who has acquired from another individual shares of Common Stock or ADSs of Sony Corporation as a legatee, heir or donee even though neither the acquiring individual nor the deceased nor donor is a Japanese resident.

Holders of shares of Common Stock or ADSs of Sony Corporation should consult their tax advisors regarding the effect of these taxes and, in the case of U.S. holders, the possible application of the Estate and Gift Tax Treaty between the U.S. and Japan.

United States Taxation with respect to shares of Common Stock and ADSs

The U.S. dollar amount of dividends received (prior to deduction of Japanese taxes) by a U.S. holder of ADSs or Common Stock of Sony Corporation will be included in income as ordinary income for U.S. federal income tax purposes to the extent paid out of current or accumulated earnings and profits of Sony Corporation as determined for U.S. federal income tax purposes. Subject to certain exceptions for short-term and hedged positions, the U.S. dollar amount of dividends received by a

non-corporate

U.S. holder with respect to the ADSs or Common Stock will be subject to taxation at a reduced rate if the dividends are “qualified dividends.” Dividends paid on the ADSs or Common Stock will be treated as qualified dividends if Sony Corporation was not, in the year prior to the year in which the dividend was paid, and is not, in the year in which the dividend is paid a passive foreign investment company (“PFIC”). Based on Sony Corporation’s audited financial statements and relevant market and shareholder data, Sony Corporation believes that it was not treated as a PFIC for U.S. federal income tax purposes with respect to its taxable year ended March 31, 2020. In addition, based on Sony Corporation’s audited financial statements and Sony Corporation’s current expectations regarding the value and nature of its assets, the sources and nature of its income, and relevant market and shareholder data, Sony Corporation does not anticipate becoming a PFIC for the taxable year ending March 31, 2021. Holders of ADSs and Common Stock of Sony Corporation should consult their own tax advisors regarding the availability of the reduced dividend tax rate in light of the considerations discussed above and their own particular circumstances.

Subject to applicable limitations and special considerations discussed below, a U.S. holder of ADSs or Common Stock of Sony Corporation will be entitled to a credit for Japanese tax withheld in accordance with the Treaty from dividends paid by Sony Corporation. For purposes of the foreign tax credit limitation, dividends will be foreign source income, and will generally constitute “passive” income. Foreign tax credits will not be allowed for withholding taxes imposed in respect of certain short-term or hedged positions and may not be allowed in respect of arrangements in which economic profit, after

non-U.S.

 taxes, is insubstantial. Holders of ADSs and Common Stock of Sony Corporation should consult their own tax advisors regarding the implications of these rules in light of their particular circumstances.

103

Table of Contents

Dividends paid by Sony Corporation to U.S. corporate holders of ADSs or Common Stock of Sony Corporation will not be eligible for the dividends-received deduction.

In general, a U.S. holder will recognize capital gain or loss upon the sale or other disposition of ADSs or Common Stock of Sony Corporation equal to the difference between the amount realized on the sale or disposition and the U.S. holder’s tax basis in the ADSs or Common Stock. Such capital gain or loss will be long-term capital gain or loss if the ADSs or Common Stock have been held for more than one year on the date of the sale or disposition. The net amount of long-term capital gain recognized by an individual holder is subject to lower rates of federal income taxation than ordinary income or short-term capital gain rates.

Under the Code, a U.S. holder of ADSs or Common Stock of Sony Corporation may be subject, under certain circumstances, to information reporting and possibly backup withholding with respect to dividends and proceeds from the sale or other disposition of ADSs or Common Stock, unless the U.S. holder provides proof of an applicable exemption or correct taxpayer identification number and otherwise complies with applicable requirements of the backup withholding rules. Any amount withheld under the backup withholding rules is not an additional tax and may be refunded or credited against the U.S. holder’s federal income tax liability, so long as the required information is furnished to the U.S. Internal Revenue Service.

Quantitative and Qualitative Disclosures about Market Risk

 

Sony’s business is continuously exposed to market fluctuation, such as fluctuations in currency exchange rates, interest rates or stock prices. Sony utilizes several derivative instruments, such as foreign exchange forward contracts, foreign currency option contracts, interest rate swap agreements and currency swap agreements in order to hedge the potential downside risk on the cash flow from the normal course of business caused by market fluctuation. Sony uses foreign exchange forward contracts and foreign currency option contracts primarily to reduce the foreign exchange volatility risk that transactions and accounts receivable or accounts payable denominated in yen, U.S. dollars, euros or other currencies have through the normal course of Sony’s worldwide business. Interest rate swap agreements and currency swap agreements are utilized to diversify funding conditions or to reduce funding costs, and in the Financial Services segment, these transactions are used for asset liability management. Sony uses these derivative financial instruments mainly for risk-hedging purposes as described above, and some derivative transactions, such as bond futures and bond options, are held or utilized for trading purposes in the Financial Services segment. If hedge accounting cannot be applied because the accounts receivable or accounts payable to be hedged are not yet booked, or because cash flows from derivative transactions do not coincide with the underlying exposures recorded on Sony’s balance sheet, such derivatives agreements are subject to a

mark-to-market

evaluation and their unrealized gains or losses are recognized in earnings. In addition, Sony holds marketable securities, such as straight bonds and stocks in yen or other currencies, in the Financial Services segment to obtain interest income or capital gain on the financial assets under management. These securities include a concentration of investments in long-term Japanese national government bonds, for which Sony monitors the related credit ratings and other market information on an ongoing basis. Investments in marketable securities are also subject to market fluctuation.

Sony measures the economic impact of market fluctuations on the value of derivatives agreements and marketable securities by using

Value-at-Risk

(“VaR”) analysis in order to comply with Item 11 disclosure

104

Table of Contents

requirements. VaR in this context indicates the potential maximum amount of loss in fair value resulting from adverse market fluctuations for a selected period of time and at a selected level of confidence.

The following table shows the results of VaR. These analyses for the fiscal year ended March 31, 2020 indicate the potential maximum loss in fair value as predicted by the VaR analysis resulting from market fluctuations in one day at a 95% confidence level. The VaR of currency exchange rate risk principally consists of risks arising from the volatility of the exchange rates between the yen and the U.S. dollar and between the yen and the euro, the currencies in which a significant amount of financial assets and liabilities and derivative transactions are maintained on a consolidated basis. The VaR of interest rate risk and stock price risk consists of risks arising from the volatility of the interest rates and stock prices against invested securities and derivatives transactions in the Financial Services segment.

The net VaR for Sony’s entire portfolio is smaller than the simple aggregate of VaR for each component of market risk. This is due to the fact that market risk factors such as currency exchange rates, interest rates and stock prices are not completely independent and potential profits and losses arising from each market risk may be mutually offsetting to some degree.

The disclosed VaR amounts simply represent the calculated maximum potential loss on the specified date and do not necessarily indicate an estimate of actual or future loss.

Controls and Procedures

 

Item 15(a). Disclosure Controls and Procedures

Sony has carried out an evaluation under the supervision and with the participation of Sony’s management, including the CEO and CFO, of the effectiveness of the design and operation of Sony’s disclosure controls and procedures, as defined in Rules

13a-15(e)

and

15d-15(e)

 under the Securities Exchange Act of 1934, as of March 31, 2020. Disclosure controls and procedures require that information to be disclosed in the reports Sony Corporation files or submits under the Securities and Exchange Act of 1934 is recorded, processed, summarized and reported as and when required, within the time periods specified in the applicable rules and forms, and that such information is accumulated and communicated to Sony’s management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon Sony’s evaluation, the CEO and CFO have concluded that, as of March 31, 2020, the disclosure controls and procedures were effective at the reasonable assurance level.

Item 15(b). Management’s Annual Report on Internal Control over Financial Reporting

Sony’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules

 13a-15(f)

and

15d-15(f)

under the Securities Exchange Act of 1934. Sony’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. Sony’s internal control over financial reporting includes those policies and procedures that:

(i)

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Sony;

 

(ii)

provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and

 

 

108

---

Table of Contents

expenditures of Sony are being made only in accordance with authorizations of management and directors; and

 

 

(iii)

provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Sony’s assets that could have a material effect on the financial statements.

 

 

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Sony’s management excluded AEGON Sony Life Insurance Co., Ltd. (subsequently renamed Sony Life With Insurance Co., Ltd. as of April 1, 2020) and SA Reinsurance Ltd. (collectively, the “Companies”), which became wholly-owned subsidiaries of Sony Life Insurance Co., Ltd. and consolidated subsidiaries of Sony on January 29, 2020, from its assessment of the effectiveness of Sony’s internal control over financial reporting as of March 31, 2020, except for the recognition and measurement of the goodwill. The Companies represented approximately 3% of Sony’s total assets as of March 31, 2020 (after excluding the goodwill) and less than 1% of Sony’s total sales and operating revenue for the fiscal year ended March 31, 2020. This acquisition is discussed in Note 25 to the consolidated financial statements.

Sony’s management evaluated the effectiveness of Sony’s internal control over financial reporting as of March 31, 2020 based on the criteria established in “Internal Control — Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on the evaluation, management has concluded that Sony maintained effective internal control over financial reporting as of March 31, 2020.

Sony’s independent registered public accounting firm, PricewaterhouseCoopers Aarata LLC, has issued an audit report on the effectiveness of Sony’s internal control over financial reporting as of March 31, 2020, presented on page

Audit Committee’s

Pre-Approval

Policies and Procedures

Consistent with the U.S. Securities and Exchange Commission rules regarding auditor independence, Sony Corporation’s Audit Committee is responsible for appointing, reviewing and setting compensation, retaining, and overseeing the work of Sony’s independent auditor, so that the auditor’s independence will not be impaired. The Audit Committee established a formal policy requiring

pre-approval

of all audit and permissible

non-audit

services provided by the independent auditor to Sony Corporation or any of its subsidiaries. The Audit Committee periodically reviews this policy with due regard for compliance with laws and regulations of host countries where Sony Corporation is listed.

Prior to the engagement of the independent auditor for the following fiscal year’s audit, management in charge of accounting or other relevant areas (“Accounting Management”) submits an application form to the Audit Committee for comprehensive

pre-approval

of all recurring services expected to be rendered during that year, other than services that are classified as “Tax” related services (“Tax Services”). In order to obtain comprehensive

pre-approval,

Accounting Management must designate in which of two categories (Audit and

Non-Audit)

the services will be classified as well as fees expected, both for each category in the aggregate and for each individual service, and detailed

back-up

information regarding each service to the extent possible to ensure that the Audit Committee knows precisely what particular service and the expected fees it is being asked to

pre-approve

and that the scope of any service or the expected fees approved is unambiguous. Any additional services not within the scope of comprehensive

pre-approval

and Tax Services require the Audit Committee’s separate

pre-approval

on an individual basis. The Audit Committee approves, if necessary, any changes in terms, conditions and fees resulting from changes in the scope of services to be provided or from other circumstances, with respect to both services that are subject to comprehensive and individual

pre-approval.

The Audit Committee or its designee establishes procedures to assure that the independent auditor is aware in a timely manner of the services that have been

pre-approved.

Disclosure About Differences in Corporate Governance

The table below discloses the significant ways in which Sony’s corporate governance practices differ from those required for U.S. companies under the listing standards of the New York Stock Exchange (“NYSE”). As a foreign private issuer listed on the NYSE, Sony Corporation is exempt from most of the exchange’s corporate governance standards requirements. For further information on Sony’s corporate governance practices and history, please refer to “Board Practices” in “Item 6.

Directors, Senior Management and Employees

.”

NYSE Standards		Sony’s Corporate Governance Practices
Board Independence.  A majority of board directors must be independent.		Sony Corporation has adopted the “Company with Three Committees” corporate governance system under the Companies Act. Sony Corporation’s Board Charter requires its board to consist of between 10 to 20 directors.   The Companies Act does not require Sony Corporation to have a majority of “independent” (in the meaning given by the NYSE Corporate Governance Standards) directors on its board; rather, it requires Sony Corporation to have a majority of “outside” directors (the definition of the term “outside” director is summarized below) on each of three statutory committees (the Nominating Committee, the Audit Committee and the Compensation Committee).
Director Independence.  A director is not independent if such director is   (i) a person who the board determines has a material direct or indirect relationship with the company, its parent or a consolidated subsidiary;   (ii) a person who, within the last three years, has been an employee of the company or has an immediate family member of an executive officer of the company, its parent or a consolidated subsidiary;   (iii) a person who had received, or whose immediate family member had received, during any 12-month period within the last three years, more than 120,000 U.S. dollars per year in direct compensation from the company, its parent or a consolidated subsidiary, other than director and committee fees or deferred compensation for prior services (provided such compensation is not contingent in any way on continued service);   (iv) (A) a person who is, or whose immediate family member is, a current partner or employee of a firm that is the company’s internal or external auditor; (B) a person whose immediate family member is a partner of such a firm; (C) a person who has an immediate family member who is a current employee of such a firm and who personally participates in the firm’s audit, assurance or tax compliance (but not tax planning) practice; or (D) a person who was, or has an immediate family member who was, within the last three years, a partner or employee of such a firm and personally worked on the listed company’s audit within that time;   (v) a person who is, or whose immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of		“Outside” director is defined in the Companies Act as a person who satisfies all of the requirements (i) through (v) below:   (i) a person who is not a Director of Sony Corporation or any of its subsidiaries engaged in the business operations of Sony Corporation or such subsidiaries, as the case may be, or a Corporate Executive Officer or general manager or other employee (“Group Executive Director, etc.”) of Sony Corporation or any of its subsidiaries and who has not been a Group Executive Director, etc. of Sony Corporation or any of its subsidiaries for ten years prior to assuming his/her office; (ii) if a person who has been a director, accounting counselor (if the accounting counselor is a juridical person, a member who is in charge of the affairs), or corporate auditor of Sony Corporation or any of its subsidiaries (excluding a person who has been a Group Executive Director, etc.) at the time within ten years prior to assuming his/her office, a person who has not been a Group Executive Director, etc. of Sony Corporation or any of its subsidiaries for ten years prior to assuming his/her office as a director, an accounting counselor, or a corporate auditor; (iii) a person who is not a director or a Corporate Executive Officer or general manager or other employee of a parent company or any entity which controls the management of Sony Corporation; (iv) a person who is not a Group Executive Director, etc. of a direct/indirect subsidiary of Sony Corporation or any entity the management of which is directly or indirectly controlled by Sony Corporation; and (v) a person who is not a spouse or relative within the second degree of kinship of a Director or a Corporate Executive Officer or general manager or other employee of Sony Corporation.

the listed company’s present executive officers at the same time serves or served on that company’s compensation committee; or   (vi) an executive officer or employee of a company, or has an immediate family member of an executive officer of a company, that makes payments to, or receives payments from, the listed company, its parent or a consolidated subsidiary for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of 1 million U.S. dollars or 2% of such other company’s consolidated gross revenues		Under the Companies Act, a director’s status as an “outside” director is unaffected by the director’s compensation, his or her affiliation with business partners, or the board’s affirmative determination of independence. On the other hand, under the Companies Act, a director who has had a career as a management director, corporate executive officer, or other employee of the company, its subsidiaries or other group companies is by definition not an “outside” director.
		Sony Corporation’s Board Charter includes a provision requiring that each “outside” director:   (i) Shall not have received directly from Sony Group, during any consecutive 12-month period within the last three years, more than an amount equivalent to 120,000 U.S. dollars, other than Director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service); and   (ii) Shall not be an executive director, a corporate executive officer, a general manager or other employee of any company whose aggregate amount of transactions with Sony Group, in any of the last three fiscal years, exceeds the greater of an amount equivalent to 1,000,000 U.S. dollars, or 2% of the annual consolidated sales of such company;
		In addition, the Securities Listing Regulations of the Tokyo Stock Exchange require Sony Corporation to make efforts to have at least one “Independent Director” on the Board of Directors. “Independent Director” is defined in the Securities Listing Regulations of the Tokyo Stock Exchange as an “outside” director who is unlikely to have conflicts of interest with shareholders. According to the guidelines of the Tokyo Stock Exchange, if a person falls in any of the categories listed below, such person, in principle, will be considered to have a conflict of interest with shareholders of the listed company.   (1) A person for which the listed company is a major client or a person who executes business of a person for which the listed company is a major client;   (2) A major client of the listed company or a person who executes business of a major client of the listed company;   (3) A consultant, accounting professional, or legal professional (or, if such consultant, accounting professional, or legal professional is a juridical person, a member of such juridical person) of
		the listed company who receives a large amount of money or other consideration other than remuneration for directorship/auditorship from such listed company;

NYSE Standards		Sony’s Corporate Governance Practices
		(4) A person who has fallen in any of categories (1) through (3) listed above until recently;   (5) A person who has fallen in any of categories (a) or (b) listed below for ten years prior to assuming his/her office:            (a) A person who executes business of a parent company of the listed company or a director who does not execute business of a parent company of the listed company; or            (b) A person who executes business of a fellow subsidiary of the listed company.
		(6) A close relative of a person who falls in any of categories (a) through (f) listed below (only if such person is significant):            (a) A person who falls in any of (1) through (5) listed above;            (b) A person who executes business of a subsidiary of the listed company;            (c) A director who does not execute business of a subsidiary of the listed company of a subsidiary of the listed company;            (d) A person who executes business of a parent company of the listed company or a director who does not execute business of a parent company of the listed company;            (e) A person who executes business of a fellow subsidiary of the listed company; or            (f) A person who has fallen in any of categories (b) or (c) listed above or a person who has executed business of the listed company until recently.
		As of June 26, 2020, 9 of the 12 members of Sony Corporation’s Board of Directors qualified as “outside” directors. In addition, all 9 “outside” directors are qualified and designated as “Independent Directors” under the Securities Listing Regulations of the Tokyo Stock Exchange.
Executive Sessions. Non-management directors must meet in regularly scheduled executive sessions without management. Independent directors should meet alone in an executive session at least once a year.		An “outside” director, as defined under the Companies Act, is equivalent to a “non-management director” under the NYSE rules because an “outside” director does not engage in the execution of business operations of the company.   The outside/non-management Directors generally meet several times a year without management, though neither the Companies Act nor Sony Corporation’s Board Charter requires non-management Directors to meet regularly without management and there is no requirement for the outside Directors to meet alone in an executive session at least once a year.

NYSE Standards		Sony’s Corporate Governance Practices
Nominating/Corporate Governance Committee.  A nominating/corporate governance committee of independent directors is required. The committee must have a charter that addresses the purpose, responsibilities (including development of corporate governance guidelines) and annual performance evaluation of the committee.		Sony Corporation’s Nominating Committee shall consist of at least three Directors. Under the Companies Act, the Committee is responsible for determining the contents of proposals regarding the appointment and dismissal of Directors to be submitted for approval to the shareholders’ meeting. Unlike listed U.S. companies under NYSE rules, it is not responsible for developing governance guidelines or overseeing the evaluation of the board and management. Under the Companies Act, a majority of its members shall be “outside” directors, as defined under the Companies Act. Sony Corporation’s Board Charter requires at least one of the Directors on the Committee to be a Corporate Executive Officer.
Compensation Committee.  A compensation committee of independent directors is required. The committee must have a charter that addresses the purpose, responsibilities and annual performance evaluation of the committee. In addition, in accordance with the SEC rules adopted pursuant to Section 952 of the Dodd-Frank Act, NYSE listing standards expanded the factors relevant in determining whether a committee member has a relationship to the company that will materially affect that member’s duties to the compensation committee and provided compensation committees the authority to engage compensation advisers. Additionally, the committee may obtain or retain the advice of a compensation adviser only after taking into consideration all factors relevant to determining that adviser’s independence from management, unless the adviser’s role is (i) limited to consulting on a generally applicable broad-based plan or (ii) is providing information that is not customized for the issuer or is not customized by the adviser and about which the adviser does not provide advice.		Sony Corporation’s Compensation Committee shall consist of at least three Directors. Under the Companies Act, a majority of its members shall be “outside” directors, as defined under the Companies Act. Sony Corporation’s Board Charter prohibits the CEO, the COO and/or the CFO (or a person at any equivalent position) from serving on the Compensation Committee. Under the Companies Act, the Committee is responsible for, among others, determining the compensation of each director and Corporate Executive Officer.
Audit Committee.  An audit committee satisfying the independence and other requirements of Rule  10A-3 under the Exchange Act is required. The committee must have at least three members. All members must be independent. The committee must have a charter addressing the committee’s purpose, an annual performance evaluation of the committee and the duties and responsibilities of the committee.		Sony Corporation’s Audit Committee shall consist of at least three Directors. Under the Companies Act, a majority of its members shall be “outside” Directors, as defined under the Companies Act. In addition, pursuant to the Companies Act, no member of the Committee shall be a Director of the company or any of its subsidiaries who is engaged in the business operations of the company or such subsidiary, as the case may be, or a corporate executive officer of the company or any of its subsidiaries, or an accounting counselor, general manager or other employee of any of such subsidiaries. Sony Corporation’s Board Charter also requires each member of the Audit Committee to meet the independence requirements of the applicable U.S. securities laws and regulations, and requires at least one member to meet the audit committee financial expert requirements. Currently, all the members of Sony Corporation’s Audit Committee are also “independent” as defined in the NYSE Corporate Governance Standards, and two members of the Committee are qualified as audit

		committee financial experts. Sony Corporation’s Board Charter discourages any Audit Committee member from concurrently being a member of other Committees.
Equity Compensation Plans.  Equity compensation plans require shareholder approval, subject to limited exemptions.		Under the Companies Act, if Sony Corporation wishes to adopt an equity compensation plan under which stock acquisition rights or shares of common stock are granted on specially favorable conditions, except where all of its shareholders are granted rights to subscribe for such stock acquisition rights/shares of common stock or such stock acquisition rights/shares of common stock are gratuitously allocated to all of its shareholders, each on a pro rata basis, then Sony Corporation must obtain shareholder approval by a “special resolution” at a General Meeting of Shareholders, where the quorum is one-third of the total number of voting rights of all of its shareholders and the approval by at least two-thirds of the number of voting rights of all the shareholders represented at the meeting is required under Sony Corporation’s Articles of Incorporation.   On the other hand, under the Companies Act, if Sony Corporation wishes to adopt an equity compensation plan under which stock acquisition rights or shares of common stock are granted against fair value thereof, such plan can be adopted by the resolution of Sony Corporation’s Compensation Committee, and grants of stock acquisition rights or shares pursuant to such plan may be decided by a resolution of the Board of Directors or a determination by a Corporate Executive Officer to whom the authority to make such determination has been delegated, and no shareholder approval is required.
Corporate Governance Guidelines. Corporate governance guidelines must be adopted and disclosed.		Sony Corporation is required to disclose the status of its corporate governance under the Companies Act, Financial Instruments and Exchange Act and its related regulations, and the Securities Listing Regulations of the Tokyo Stock Exchange; however, Sony Corporation does not have corporate governance guidelines that cover all the requirements described in the NYSE Corporate Governance Standards, as many of the provisions do not apply to Sony Corporation. Details of the status are posted on the following website: https://www.sony.net/SonyInfo/csr_report/governance/
Code of Ethics.  A code of business conduct and ethics for directors, officers and employees must be adopted and disclosed, along with any waivers of the code for directors or executive officers.		Although this provision of the NYSE Corporate Governance Standards does not apply to Sony Corporation, Sony Corporation has adopted a code of conduct to be observed by all its directors, officers and other employees. The code of conduct is available at: https://www.sony.net/SonyInfo/csr_report/compliance/code.html   The code’s content covers principal items described in the NYSE Corporate Governance Standards.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Sony Corporation (Sony Kabushiki Kaisha)

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Sony Corporation and its subsidiaries (the “Company”) as of March 31, 2020 and 2019, and the related consolidated statements of income, comprehensive income, cash flows and changes in stockholders’ equity for each of the three years in the period ended March 31, 2020, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of March 31, 2020, based on criteria established in

Internal Control — Integrated Framework

(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of March 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended March 31, 2020 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of March 31, 2020, based on criteria established in

Internal Control — Integrated Framework

(2013) issued by the COSO.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company changed the manner in which it accounts for leases as of April 1, 2019.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 15(b). Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded AEGON Sony Life Insurance Co., Ltd. (subsequently renamed Sony Life With Insurance Co., Ltd. as of April 1, 2020) and SA Reinsurance Ltd. (collectively, the “Companies”) from its assessment of internal control over financial reporting as of March 31, 2020 because they were acquired by the Company in purchase business combinations during the year ended March 31, 2020. We have also excluded the Companies from our audit of internal control over financial reporting. The Companies are wholly-owned subsidiaries whose total assets and total sales and operating revenue excluded from management’s assessment and our audit of internal control over financial reporting collectively represent approximately 3% and less than 1%, respectively, of the related consolidated financial statement amounts as of and for the year ended March 31, 2020.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Realizability of deferred tax assets for entity’s national tax filing group in Japan

As described in Note 2 and Note 22 to the consolidated financial statements, carrying amounts of deferred tax assets require a reduction by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish a valuation allowance for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. Management’s judgments related to this assessment consider, among other matters, the nature, frequency and severity of current and cumulative losses on an individual tax jurisdiction basis, forecasts of future income after consideration of uncertain tax positions, excess of carrying value over the tax basis of net assets, the duration of statutory carryforward periods, the past utilization of net operating loss carryforwards prior to expiration, as well as prudent and feasible tax planning strategies which would be employed by the Company to prevent net operating loss and tax credit carryforwards from expiring unutilized. For the fiscal year ended March 31, 2020, based on an assessment of the available positive and negative evidence including the Company’s positive earnings for the past several years, due to the uncertainty of the forecast of future income impacted by the spread of

COVID-19

from early 2020, the Company has continued to establish a valuation allowance against the deferred tax assets in the Japan consolidated national tax filing group, except for the amounts expected to be offset with taxable temporary differences. The valuation allowance of 274,761 million yen relating to Japan national taxes was established as of March 31, 2020.

The principal considerations for our determination that performing procedures relating to the realizability of deferred tax assets for the Japan consolidated national tax filing group was a critical audit matter are (i) there was significant judgment involved by management in an assessment of the available positive and negative evidence including forecasted income, and (ii) this in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to management’s assessment, including forecasts of future income.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s assessment of the realizability of deferred tax assets, including assessing positive and negative evidence including future forecasts for the Japan consolidated national filing group. These procedures also included, among others, evaluating management’s weighing of positive and negative evidence; testing the completeness of the positive and negative evidence used; and evaluating the reasonableness of assumptions used by management, including the uncertainty regarding the Company’s ability

to generate income in the Japan consolidated national filing group. Evaluating management’s assumptions related to generating income in Japan involved evaluating whether the assumptions used by management were reasonable considering the current and past performance of the Company.

Liabilities for future insurance policy benefits and deferred acquisition costs

As described in Note 2 and 10 to the consolidated financial statements, liabilities for future insurance policy benefits include liabilities for minimum guarantee benefits related to certain variable annuity and variable life insurance contracts. The Company has elected fair value options for variable annuity contracts with minimum guarantee benefits in their entirety, which includes liabilities for minimum guarantee benefits. The fair value of the liabilities for minimum guarantee benefits is calculated as the present value of future expected cash flows. The significant assumptions used in the valuation include mortality rates, lapse rates, discount rates, and investment yields. As of March 31, 2020, the liabilities for minimum guarantee benefits for the variable annuity contracts were 64,045 million yen. Liabilities are also established for the variable life contracts that include minimum guarantee benefits features. For these contract features, the liabilities for minimum guarantee benefits are calculated using current best estimate assumptions and are based on the ratio of the present value of expected total excess payments divided by the present value of expected total assessments over the life of the contract. The significant assumptions in the valuation include mortality rates, lapse rates, discount rates and investment yields. As of March 31, 2020, the liabilities for minimum guarantee benefits for the variable life contracts were 79,860 million yen. Also, the Company defers acquisition costs that are related directly to the acquisition or renewal of insurance policies to the extent such costs are determined to be recoverable from future profits. Among them, the deferred insurance acquisition costs for

non-traditional

life insurance contracts such as variable annuity contracts, variable life contracts, and investment contracts are amortized over the expected life at a constant rate based on the present value of the estimated gross profit. The present value of the estimated gross profit is affected by a number of assumptions, including investment yields, mortality rates, lapse rates and discount rates. At March 31, 2020, deferred insurance acquisition costs for

non-traditional

life insurance contracts were 206,363 million yen.

The principal considerations for our determination that performing procedures relating to assumptions used for measurement of the liabilities for minimum guarantee benefits and deferred insurance acquisition costs for

non-traditional

life insurance contracts is a critical audit matter are (i) there was significant judgment involved by management in developing the aforementioned assumptions, (ii) this in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating audit evidence related to management’s assumptions, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge to assist in performing procedures and evaluating the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the design and operating effectiveness of controls relating to the significant assumptions of the liabilities for minimum guarantee benefits and deferred insurance acquisition costs for

non-traditional

life insurance contracts, which included controls over the development of significant assumptions, such as mortality rates, lapse rates, discount rates, and investment yields, and controls over the completeness and accuracy of data used by management in developing the assumptions, such as past claim, lapse, discount rates, and investment yield data. These procedures also included, among others, testing the completeness and accuracy of data used by management in developing the assumptions; and considering the reasonableness of the assumptions across products, in relation to prior periods, and in relation to management’s historical experience or industry knowledge. Professionals with specialized skill and knowledge were used to assist in evaluating the reasonableness of the methodology used by management to determine their assumptions and the reasonableness of the aforementioned assumptions used in the valuation of the liabilities for minimum guarantee benefits and deferred insurance acquisition costs for

non-traditional

life insurance contracts, based on industry knowledge and the Company’s historical experience.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Notes to Consolidated Financial Statements

 

Sony Corporation and Consolidated Subsidiaries

1 .	Nature of operations

 

 

 

 

Sony Corporation and its consolidated subsidiaries (hereinafter collectively referred to as “Sony”) are engaged in the development, design, production, manufacture, offer and sale of various kinds of electronic equipment, instruments and devices for consumer, professional and industrial markets such as network services, game hardware and software, televisions, audio and video recorders and players, still and video cameras, smartphones, and image sensors. Sony’s primary manufacturing facilities are located in Asia including Japan. Sony also utilizes third-party contract manufacturers for certain products. Sony’s products and services are marketed throughout the world by sales subsidiaries and unaffiliated distributors as well as direct sales and offers via the internet. Sony is engaged in the development, production, manufacture, and distribution of recorded music and the management and licensing of the words and music of songs as well as production and distribution of animation titles, including game applications based on the animation titles. Sony is also engaged in the production, acquisition and distribution of motion pictures and television programming and the operation of television and digital networks. Further, Sony is also engaged in various financial services businesses, including life and

non-life

insurance operations through its Japanese insurance subsidiaries and banking operations through a Japanese internet-based banking subsidiary.

2 .	Summary of significant accounting policies

 

 

 

 

The accompanying consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform with U.S. GAAP. These adjustments were not recorded in the statutory books and records as Sony Corporation and its subsidiaries in Japan maintain their records and prepare their statutory financial statements in accordance with accounting principles generally accepted in Japan, while its foreign subsidiaries maintain their records and prepare their financial statements in conformity with accounting principles generally accepted in the countries of their domicile.

(1)	Significant accounting policies

Basis of consolidation and accounting for investments in affiliated companies -

The consolidated financial statements include the accounts of Sony Corporation and its majority-owned subsidiary companies, general partnerships and other entities in which Sony has a controlling interest, and variable interest entities (“VIEs”) for which Sony is the primary beneficiary. All intercompany transactions and accounts are eliminated. Investments in business entities in which Sony does not have control, but has the ability to exercise significant influence over operating and financial policies, generally through

20-50%

ownership, are accounted for under the equity method. In addition, investments in general partnerships in which Sony does not have a controlling interest and limited partnerships are also accounted for under the equity method if more than minor influence over the operation of the investee exists (generally through more than

3-5%

ownership). When the interest in the partnership is so minor that Sony has no significant influence over the operation of the investee, the interest in the partnership is carried at fair value. Under the equity method, investments are stated at cost plus/minus Sony’s portion of equity in undistributed earnings or losses. Sony’s equity in current earnings or losses of such entities is reported net of income taxes and is included in operating income (loss) after the elimination of unrealized intercompany profits. If the value of an investment has declined and is judged to be other-than-temporary, the investment is written down to its estimated fair value.

On occasion, a consolidated subsidiary or an affiliated company accounted for by the equity method may issue its shares to third parties in either a public or private offering or upon conversion of convertible debt to common stock at amounts per share in excess of or less than Sony’s average per share carrying value. With respect to such transactions, the resulting gains or losses arising from the change in ownership interest are recorded in earnings within the fiscal year in which the change in interest transactions occurs.

Gains or losses that result from a loss of a controlling financial interest in a subsidiary are recorded in earnings along with fair value remeasurement gains or losses on any retained investment in the entity, while a change in interest

in

a consolidated subsidiary that does not result in a change in control is accounted for as a capital transaction and no gains or losses are recorded in earnings.

SONY

CORPORATION AND CONSOLIDATED SUBSIDIARIES

The excess of the cost over the underlying net equity of investments in consolidated subsidiaries and affiliated companies accounted for on an equity basis is allocated to identifiable tangible and intangible assets and liabilities based on fair values at the date of acquisition. The unassigned residual value of the excess of the cost over Sony’s underlying net equity is recognized as goodwill as a component of the investment balance.

Use of estimates -

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include those used in determining the valuation of investment securities, valuation of inventories, fair values of long-lived assets, fair values of goodwill and other intangible assets, fair values of assets and liabilities assumed in business combinations, product warranty liability, pension and severance plans, valuation of deferred tax assets, uncertain tax positions, film costs, and insurance related liabilities. Actual results could significantly differ from those estimates. The timing and extent to which the spread of COVID-19 may negatively impact Sony’s business will depend on future developments, which are highly uncertain. This uncertainty could result in greater variability in accounting estimates and assumptions, including, but not limited to, those used in reviewing goodwill and long-lived assets for impairment and the valuation of deferred tax assets.

Translation of foreign currencies -

All asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at appropriate fiscal year end exchange rates and all income and expense accounts are translated at exchange rates that approximate those rates prevailing at the time of the transactions. The resulting translation adjustments are accumulated as a component of accumulated other comprehensive income. Upon remeasurement of a previously held equity interest in accordance with the accounting guidance for business combinations achieved in stages, accumulated translation adjustments, if any, are included in earnings.

Monetary assets and liabilities denominated in foreign currencies are translated at appropriate fiscal year end exchange rates and the resulting translation gains or losses are recognized into income.

Cash, cash equivalents and restricted cash -

Cash and cash equivalents include all highly liquid investments, with original maturities of three months or less, that are readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates. Sony includes restricted cash within cash and cash equivalents in the statement of cash flows.

Marketable debt and equity

securities

-

Debt securities designated as

available-for-sale

are carried at fair value with

unrealized

gains or losses included as a component of accumulated other comprehensive income, net of applicable taxes. Equity securities that have a readily determinable fair value, and debt securities classified as trading securities, are carried at fair value with unrealized gains or losses included in income. Debt securities that are expected to be

held-to-maturity

are carried at amortized cost. Individual securities classified as either

available-for-sale

or

held-to-maturity

are reduced to fair value by a charge to income when an other-than-temporary impairment is recognized. Realized gains and losses are determined on the average cost method and are reflected in income.

Sony regularly evaluates its investment portfolio to identify other-than-temporary impairments of individual debt securities. Factors that are considered by Sony in determining whether an other-than-temporary decline in value has occurred include: the length of time and extent to which the market value of the security has been less than its original cost, the financial condition, operating results, business plans and estimated future cash flows of the issuer of the security, other specific factors affecting the market value, deterioration of the credit condition of the issuer, sovereign risk, and whether or not Sony is able to retain the investment for a period of time sufficient to allow for the anticipated recovery in market value.

In evaluating the factors for debt securities designated as

available-for-sale,

Sony presumes a decline in value to be other-than-temporary if the fair value of the security is 20 percent or more below its original cost for an extended period of time (generally for a period of up to six months). This criterion is employed as a threshold to identify securities which may have a decline in value that is other-than-temporary. The presumption of an other-than-temporary impairment in such cases may be overcome if there is evidence to support that the decline

F-1

7

---

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

is temporary in nature due to the existence of other factors which overcome the duration or magnitude of the decline. On the other hand, there may be cases where impairment losses are recognized when the decline in the fair value of the security is not more than 20 percent or such decline has not existed for an extended period of time, as a result of considering specific factors which may indicate that the decline in the fair value is other-than-temporary.

When an other-than-temporary impairment of a

held-to-maturity

debt security has occurred, the amount of the other-than-temporary impairment recognized in income depends on whether Sony intends to sell the debt security or more likely than not will be required to sell the debt security before recovery of its amortized cost. If the debt security meets either of these two criteria, the other-than-temporary impairment is recognized in income, measured as the entire difference between the security’s amortized cost and its fair value at the impairment measurement date. For other-than-temporary impairment of the debt security that does not meet these two criteria, the net amount recognized in income is a credit loss, which equals the difference between the amortized cost of the debt security and its net present value calculated by discounting Sony’s best estimate of projected future cash flows at the effective interest rate implicit in the debt security prior to impairment. Any difference between the fair value and the net present value of the debt security at the impairment measurement date is recorded in accumulated other comprehensive income. Unrealized gains or losses on securities for which an other-than-temporary impairment is recognized in income are presented as a separate component of accumulated other comprehensive income.

Equity securities that do not have readily determinable fair values -

Equity securities that do not have readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. If the value of equity securities that do not have readily determinable fair values is estimated to have declined and such decline is judged to be other-than-temporary, Sony recognizes the impairment of the investment and the carrying value is reduced to its fair value. Determination of impairment is based on the consideration of several factors, including operating results, business plans and estimated future cash flows. Fair value is determined through the use of various methodologies such as discounted cash flows, valuation of recent financings and comparable valuations of similar companies.

Allowance for doubtful accounts -

Sony maintains an allowance for doubtful accounts to reserve for potentially uncollectible receivables. Sony reviews accounts receivable by amounts due from customers which are past due to identify specific customers with known disputes or collectability issues. In determining the amount of the reserve, Sony makes judgments about the creditworthiness of customers based on past collection experience and ongoing credit risk evaluations.

Inventories -

Inventories in the Game & Network Services (“G&NS”), Music, Electronics Products & Solutions (“EP&S”) and Imaging & Sensing Solutions (“I&SS”) segments as well as

non-film

inventories for the Pictures segment are valued at cost, not in excess of the net realizable value – i.e., estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal, cost being determined on the “average cost” basis.

Other receivables -

Other receivables include receivables which relate to arrangements with certain component manufacturers whereby Sony procures goods, including product components, for these component manufacturers and is reimbursed for the related purchases. No revenue or profit is recognized on these transfers. Sony will repurchase the inventory at a later date from the component manufacturers as either finished goods inventory or as partially assembled product.

Film costs -

Film costs include direct production costs, production overhead and acquisition costs for both motion picture and television productions and are stated at the lower of unamortized cost or estimated fair value and

F-1

Table of Contents

SONY

CORPORATION AND CONSOLIDATED SUBSIDIARIES

classified as noncurrent assets. Film costs are amortized, and the estimated liabilities for residuals and participations are accrued using an individual-film-forecast method based on the ratio of current period actual revenues to the estimated remaining total revenues. Film costs also include broadcasting rights, which are recognized when the license period begins and the program is available for use, and consist of acquired programming to be aired on Sony’s worldwide channel network. Broadcasting rights are stated at the lower of unamortized cost or net realizable value, classified as either current or noncurrent assets based on timing of expected use. Broadcasting rights are amortized based on estimated usage or on a straight-line basis over the useful life, as appropriate, although broadcasting rights licensed under multi-year live-event sports programming agreements are generally amortized based on the ratio of the current period’s actual advertising revenue and an allocation of subscription fee revenue to the estimated total remaining attributable revenues. Estimates used in calculating the fair value of film costs and the net realizable value of broadcasting rights are based upon assumptions about future demand and market conditions and are reviewed on a periodic basis.

Property, plant and equipment and depreciation -

Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method. Useful lives for depreciation range from 2 to 50 years for buildings and from 2 to 10 years for machinery and equipment. Significant renewals and additions are capitalized at cost. Maintenance and repairs, and minor renewals and betterments are charged to income as incurred.

Leases -

When entering into a contract, Sony determines whether an arrangement contains a lease at its inception. An arrangement contains a lease if it conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Operating leases are included in operating lease

right-of-use

assets, current portion of long-term operating lease liabilities, and long-term operating lease liabilities on Sony’s consolidated balance sheets. Finance leases are included in finance lease

right-of-use

assets, current portion of long-term debt, and long-term debt on Sony’s consolidated balance sheets.

Right-of-use

assets represent Sony’s right to use an underlying asset for the lease term and lease liabilities represent Sony’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Right-of-use assets also include any lease payments or initial direct costs incurred on or before the commencement date and excludes lease incentives. In determining the present value of lease payments, Sony generally uses its incremental borrowing rate, as the implicit rate is not available for most of its leases. Sony determines its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing, taking into account the lease term and the economic environment of each country or region at commencement date. The lease terms include options to extend or terminate the lease when it is reasonably certain that Sony will exercise that option. Lease expense for operating leases recorded on the balance sheet is recognized on a straight-line basis over the lease term. Sony accounts for the lease and

non-lease

components of all underlying asset classes as a single lease component. Sony has applied the short-term lease exception for leases with a term of one year or less, where right-of-use assets and lease liabilities are not recognized and the expense is recognized on a straight-line basis

.

As of April 1, 2019, Sony adopted Accounting Standards Update (“ASU”) 2016-02, which amends leasing guidance, on a modified retrospective basis with no restatement of comparative periods. Prior to the adoption of ASU 2016-02 on April 1, 2019, right-of-use assets and lease liabilities for operating leases were not recognized in Sony’s consolidated balance sheet. For the detailed effect of the adoption of the new standard on Sony’s results of operations and financial position, refer to Note 2 (2) Recently adopted accounting pronouncements.

Goodwill and other intangible assets -

Goodwill and indefinite lived intangible assets are tested annually for impairment during the fourth quarter of the fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. Such an event or change in circumstances would include unfavorable variances from established business plans, significant changes in forecasted results or volatility inherent to external markets and industries, which are periodically reviewed by Sony’s management.

In the fourth quarter of the fiscal year ended March 31, 2020, Sony elected not to perform an optional qualitative assessment of goodwill and instead proceeded directly to a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. Reporting units are Sony’s operating segments or one

F-1

9

---

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

level below the operating segments. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the total amount of goodwill allocated to the reporting unit. Indefinite lived intangible assets are tested for impairment by comparing the fair value of the intangible asset with its carrying value, and if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

The fair value of a reporting unit or indefinite lived intangible asset is generally determined using a discounted cash flow analysis. This approach uses significant estimates and assumptions, including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, earnings multiples, the determination of appropriate comparable entities and the determination of whether a premium or discount should be applied to comparables. Consideration is also given to Sony’s market capitalization in relation to the sum of the calculated fair values of the reporting units, including reporting units with no goodwill, and taking into account corporate level assets and liabilities not assigned to individual reporting units as well as a reasonable control premium.

The assumptions used for projected future cash flows and the timing of such cash flows are based on the forecast and

mid-range

plan (“MRP”) of each reporting unit and take into account such factors as historical experience, market and industry information, and current and forecasted economic conditions. Perpetual growth rates are utilized to determine a terminal cash flow value and are generally set after the three-year forecasted period for the MRP. Certain reporting units, such as those in the Pictures segment, utilize longer forecast periods and base the terminal value on an exit price using an earnings multiple applied to the final year of the forecasted earnings, which also takes into consideration a control premium. Discount rates are derived from the weighted average cost of capital of market participants in similar businesses.

Management believes that the assumptions used to estimate the fair value in the goodwill impairment tests are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower than currently anticipated cash flows and fair values due to unforeseen changes in assumptions could negatively affect the valuations, which may result in Sony recognizing impairment charges for goodwill and indefinite lived intangible assets in the future.

When a business within a reporting unit is disposed of, goodwill is allocated to the disposed business using the relative fair value method.

Intangible assets with finite useful lives mainly consist of patent rights,

know-how,

license agreements, customer relationships, trademarks, software to be sold, leased or otherwise marketed,

internal-use

software, music catalogs, artist contracts, and television carriage contracts (broadcasting agreements). Patent rights,

know-how,

license agreements, trademarks, software to be sold, leased or otherwise marketed, and

internal-use

software are generally amortized on a straight-line basis over 3 to 10 years. Customer relationships, music catalogs, artist contracts and television carriage contracts (broadcasting agreements) are generally amortized on a straight-line basis over 10 to 44 years.

Capitalized software -

The costs related to establishing the technological feasibility of software to be sold, leased or otherwise marketed are expensed as incurred as a part of research and development in cost of sales. Costs that are incurred to produce the finished product after technological feasibility is established are capitalized and amortized to cost of sales over the estimated economic life, which is generally three years. The technological feasibility of game software is established when the product master is completed. Consideration to capitalize game software development costs before this point is limited to the development costs of games for which technological feasibility can be proven at an earlier stage. At each balance sheet date, Sony performs reviews to ensure that unamortized capitalized software costs remain recoverable from future profits of the related software products.

The costs incurred for

internal-use

software during the application development stage are capitalized and amortized, mainly to selling, general and administrative expenses, on a straight-line basis over the estimated useful life. Costs related to the preliminary project stage and post implementation activities are expensed as incurred.

Costs that vary with and are directly related to the acquisition or renewal of insurance policies are deferred as long as they are recoverable. The deferred insurance acquisition costs include such items as commissions, medical examination costs and inspection report fees, and are subject to recoverability testing at least annually to ensure that the capitalized amounts do not exceed the present value of anticipated gross profits or premiums less benefits and maintenance expenses, as applicable. The deferred insurance acquisition costs for traditional life insurance contracts are amortized over the premium-paying period of the related insurance policies using assumptions consistent with those used in computing policy reserves. The deferred insurance acquisition costs for

non-traditional

life insurance contracts are amortized over the expected life at a constant rate based on the present value of the estimated gross profit. Investment yields, mortality rates, lapse rates and discount rates are used as important assumptions for the present value of the estimated gross profit.

Product warranty -

Sony provides for the estimated cost of product warranties at the time revenue is recognized. The product warranty is calculated based upon product sales, estimated probability of failure and estimated cost per claim. The variables used in the calculation of the provision are reviewed on a periodic basis.

Future insurance policy benefits -

Liabilities for future insurance policy benefits are primarily comprised of the present value of estimated future payments to policyholders. These liabilities are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. These assumptions are reviewed on a periodic basis. Liabilities for future policy benefits includes the liabilities for the minimum guarantee benefits of variable annuities and variable life insurance contracts. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for future insurance policy benefits.

Policyholders’ account in the life insurance business -

Liabilities for policyholders’ account in the life insurance business represent the contract value that has accrued to the benefit of the policyholders as of the balance sheet date. This liability is generally equal to the accumulated account deposits, plus interest credited, less policyholder withdrawals and other charges assessed against the account balances. Liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business.

Impairment of long-lived assets -

Sony reviews the recoverability of the carrying value of its long-lived assets held and used, other than goodwill and intangible assets with indefinite lives, and assets to be disposed of, whenever events or changes in circumstances indicate that the individual carrying amount of an asset or asset group may not be recoverable. Long-lived assets to be held and used are reviewed for impairment by comparing the carrying value of the asset or asset group with their estimated undiscounted future cash flows. If the cash flows are determined to be less than the carrying value of the asset or asset group, an impairment loss would be recognized during the period for the amount by which the carrying value of the asset or asset group exceeds estimated fair value. Long-lived assets that are to be disposed of other than by sale are considered held and used until they are disposed of. Long-lived assets that are to be disposed of by sale are reported at the lower of their carrying value or fair value less cost to sell and are not depreciated. Fair value is determined using the present value of estimated net cash flows or comparable market values. This approach uses significant estimates and assumptions including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates applied to determine terminal values, determination of appropriate market comparables and the determination of whether a premium or discount should be applied to comparables.

Management believes that the estimates of future cash flows and fair values are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower future cash flows and fair values due to unforeseen changes in Sony’s businesses or assumptions could negatively affect the valuations of long-lived assets.

Fair value measurement -

Sony measures fair value as an exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Sony has elected the fair value option in the banking business for certain foreign securities. The election was made to mitigate accounting mismatches related to fluctuations of foreign exchange rates by allowing the gains and losses on the translation of these securities to be included in current earnings. Sony has also elected the fair value option for certain future insurance policy benefits and policyholders’ account in the life insurance business which are not normally measured at fair value. The election was made to mitigate accounting mismatches related to the changes in the fair value between liabilities for those future insurance policy benefits and policyholders’ account due to changes in the minimum guarantee risk of contracts of variable annuities with minimum guarantee benefits, and the underlying investment managed for policyholders and derivatives. Changes in fair value resulting from changes in instrument-specific credit risk were estimated by incorporating the certain subsidiary’s current credit spreads, and are recognized in other comprehensive income, net of tax.

The accounting guidance for fair value measurements specifies a hierarchy of inputs to valuation techniques based on the extent to which inputs used in measuring fair value are observable in the market. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Sony’s assumptions about the assumptions that market participants would use in pricing the asset or liability. Observable market data is used if such data is available without undue cost and effort. Each fair value measurement is reported in one of three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety.

These levels are:

Level 1		—		Inputs are unadjusted quoted prices for identical assets and liabilities in active markets.
Level 2		—		Inputs are based on observable inputs other than level 1 prices, such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.
Level 3		—		One or more significant inputs are unobservable.

 

 

 

 

When available, Sony uses unadjusted quoted market prices in active markets to measure fair value and classifies such items within level 1. If quoted market prices are not available, fair value is based upon internally developed valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates, currency rates and option volatilities. Items valued using internally generated models are classified according to the lowest level input that is significant to the valuation. For certain financial assets and liabilities, Sony determines fair value using third-party information such as indicative quotes from dealers and quantitative input from investment advisors following Sony’s established valuation procedures including validation against internally developed prices. Additionally, Sony considers both counterparty credit risk and Sony’s own creditworthiness in determining fair value. Sony attempts to mitigate credit risk to third parties by entering into netting agreements and actively monitoring the creditworthiness of counterparties and its exposure to credit risk through the use of credit limits and by selecting major international banks and financial institutions as counterparties.

Transfers between levels are deemed to have occurred at the beginning of the interim period in which the transfers occur.

Derivative financial instruments -

All derivatives are recognized as either assets or liabilities in the consolidated balance sheets at fair value on a gross basis. Changes in the fair value of derivative financial instruments are either recognized periodically in income or stockholders’ equity (as a component of accumulated other comprehensive income), depending on whether the derivative financial instrument qualifies as a hedge and the derivative is being used to hedge changes in fair value or cash flows.

The accounting guidance for hybrid financial instruments permits an entity to elect fair value remeasurement for any hybrid financial instrument if the hybrid instrument contains an embedded derivative that would otherwise be required to be bifurcated and accounted for separately under accounting guidance for

F-2

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

derivative instruments and hedging activities. The election to measure the hybrid instrument at fair value is made on an

instrument-by-instrument

basis and is irreversible. Certain subsidiaries in the Financial Services segment had hybrid financial instruments, disclosed in Note 7 as debt securities, that contain embedded derivatives where the entire instrument was carried at fair value.

In accordance with accounting guidance for derivative instruments and hedging activities, various derivative financial instruments held by Sony are classified and accounted for as described below.

Fair value hedges

Changes in the fair value of derivatives designated as fair value hedges for recognized assets or liabilities or unrecognized firm commitments are recognized in earnings as offsets to changes in the fair value of the related hedged assets or liabilities.

Cash flow hedges

Changes in the fair value of derivatives designated as cash flow hedges for forecasted transactions or exposures associated with recognized assets or liabilities are initially recorded in other comprehensive income and reclassified into earnings when the hedged transaction affects earnings. The time value component of the fair value of option contracts is excluded from the assessment of hedge effectiveness and recognized in earnings on a straight-line basis over the life of the hedging instruments. Any difference between the change in fair value of the excluded component and

the

accumulated amount recognized in earnings on a straight-line basis is recognized in other comprehensive income.

Derivatives not designated as hedges

Changes in the fair value of derivatives that are not designated as hedges are recognized immediately in earnings.

Assessment of hedges

When applying hedge accounting, Sony formally documents all hedging relationships between the derivatives designated as hedges and the hedged items, as well as its risk management objectives and strategies for undertaking various hedging activities. Sony links all hedges that are designated as fair value or cash flow hedges to specific assets or liabilities on the consolidated balance sheets or to the specific forecasted transactions. Sony also assesses, both at the inception of the hedge and on an

on-going

basis, whether the derivatives that are designated as hedges are highly effective in offsetting changes in fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge, Sony discontinues hedge accounting.

Stock-based compensation -

Sony accounts for stock-based compensation using the fair value

-

based method and the expense is mainly included in selling, general and administrative expenses. Sony accounts for its stock acquisition rights plan using the fair value measured on the date of grant using the Black-Scholes option-pricing model. The stock acquisition rights plan is recognized, net of an estimated forfeiture rate, over the requisite service period using the accelerated method of amortization for grants with graded vesting. The estimated forfeiture rate is based on Sony’s historical experience in the stock acquisition rights plans where the majority of the vesting terms have been satisfied.

Revenue recognition -

Sony recognizes revenue in an amount that reflects the consideration Sony expects in exchange for satisfying performance obligations to transfer the goods or services promised in contracts with customers. This is in accordance with the following steps:

Step 1: Identify the contract(s) with a customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when (or as) Sony satisfies a performance obligation.

Sony owns a variety of intellectual property throughout segments and recognizes revenue through the licensing of such intellectual property. Sony has both functional and symbolic intellectual property. The licensing of functional intellectual property grants a customer a right to use Sony’s intellectual property as it exists at a point in time, and Sony satisfies its performance obligation at the point in time when the customer obtains control and is entitled to benefit from the license. The licensing of symbolic intellectual property grants a customer a right to access Sony’s intellectual property over time, and Sony satisfies its performance obligation over the license period as Sony maintains the intellectual property.

Incremental costs of obtaining a contract and costs to fulfill a contract are recognized as assets when Sony expects to recover these costs. The incremental costs of obtaining a contract are those costs that would not have been incurred if the contract had not been obtained. Costs to fulfill a contract are those costs that are directly related to a contract or to an anticipated contract and that generate or enhance resources for Sony to satisfy its performance obligations. Sony applies a practical expedient and recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less.

Performance obligations in contracts for the EP&S and I&SS segments are primarily to deliver various kinds of electronic equipment, instruments and devices to customers. Revenues from these performance obligations are generally recognized when a promised good is delivered to a customer. However, if the sales contract contains a customer acceptance provision, then revenues are recognized when the customer accepts the promised good or when a deemed acceptance occurs by the lapse of time. Revenues are also recognized over time, primarily from the provision of internet broadband network services to subscribers over the subscription period. Revenues are recognized net of anticipated returns and sales incentives.

Within the G&NS segment, revenues from hardware, peripherals and software discs are recognized when performance obligations are satisfied by transferring control to the retailer/distributor, net of anticipated returns, sales incentives and cooperative advertising obligations. Revenues from platform licensing to publishers are recognized when physical software discs are delivered. Revenues from digital game content, which is licensed functional intellectual property, are recognized when the digital content is made available for use by the licensee via an online platform, net of anticipated sales incentives and credit card chargebacks. Revenues from digital game content involving multiple performance obligations, such as obligations to make content available on future dates, are allocated to each performance obligation based on the relative standalone selling prices that are observable in the market or Sony’s best estimate. Revenues from subscription fees for digital subscription services are recognized over the subscription period.

Within the Music segment, Sony licenses intellectual property that transfer to a customer either a right to use Sony’s intellectual property as it exists at the point in time in which the license is granted, or a right to access Sony’s intellectual property as it exists throughout the license period. Revenues are recognized when the customer has the right to use or access the intellectual property and obtains control of the use or access of that license. Digital revenues include revenues from contracts with digital streaming services typically recognized as a single performance obligation, which is ongoing access to intellectual property in an evolving library of content over the contract term, predicated on: (1) the business practice and contractual ability to remove specific content without a requirement to replace the content and without impact to minimum royalty guarantees and (2) the contracts not containing a specific listing of content subject to the license. For these contracts, revenues are recognized on the basis of sales and usage royalties, except where there is an amount of a minimum royalty guarantee that is not expected to be recouped, or a fixed fee, which is recognized on a straight-line basis over the term of the contract. Revenues from the sale of physical product such as CDs, net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public.

Within the Pictures segment, revenues from the theatrical exhibition of motion pictures are recognized as the customer exhibits the film. Revenues from the licensing of motion picture and television programming for pay and free television exhibition and other markets are recognized when the product is available for use by the licensee. Revenues for motion picture and television program licensing arrangements involving multiple performance obligations, for example a fee for multiple titles, territories or availability dates, are allocated based on the relative standalone selling price of each performance obligation using Sony’s best estimate based on available information such as market conditions and internal pricing guidelines. Each individual motion picture or television programming product delivered generally represents a separate performance obligation. Licensing revenue associated with certain renewals or extensions of existing agreements for motion pictures and television programming is recognized when the licensee can use and benefit from the content under the renewal or extension. Licensing revenue associated with minimum guarantees for symbolic intellectual property is

recognized ratably over the license term. For home entertainment distribution, revenues from the sale of physical product such as DVDs and

Blu-ray

Disc

TM

, net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public. Revenues from electronic sell-through and

video-on-demand

are recognized when the product is made available for viewing via digital distribution platforms. Revenues from the sale of broadcast advertising are recognized when the advertisement is aired, and the performance obligation in these arrangements is the delivery of advertising spots and may include a guaranteed amount of impressions. When a guarantee for a number of impressions is not achieved, revenues are not recognized until additional advertising spots are delivered to provide the guaranteed impressions. Revenues from subscription fees received by television networks are recognized when the service is provided. The performance obligation under network subscription arrangements is a license of functional intellectual property that is satisfied as programming is provided over the term of the arrangement.

Traditional life insurance policies that the life insurance subsidiary underwrites, most of which are categorized as long-duration contracts, mainly consist of whole life, term life and accident and health insurance contracts. Premiums from these policies are reported as revenue when due from policyholders.

Amounts received as payment for

non-traditional

contracts such as interest sensitive whole life contracts, individual annuity contracts and other contracts without life contingencies are recognized in policyholders’ account in the life insurance business. Revenues from these contracts are comprised of fees earned for administrative and contract-holder services, which are recognized over the period of the contracts, and included in financial services revenue.

Property and casualty insurance policies that the

non-life

insurance subsidiary underwrites are primarily automotive insurance contracts which are categorized as short-duration contracts. Premiums from these policies are reported as revenue over the period of the contract in proportion to the amount of insurance protection provided.

Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities.

Cost of sales -

Costs classified as cost of sales relate to the producing and manufacturing of products and include items such as material cost, subcontractor cost, depreciation of fixed assets, amortization of intangible assets, personnel expenses, research and development costs, and amortization of film costs related to motion picture and television productions.

Research and development costs -

Research and development costs, included in cost of sales, include items such as salaries, personnel expenses and other direct and indirect expenses associated with research and product development. Research and development costs are expensed as incurred.

Selling, general and administrative -

Costs classified as selling expenses relate to promoting and selling products and include items such as advertising, promotion, shipping and warranty expenses. General and administrative expenses include operating items such as officers’ salaries, personnel expenses, depreciation of fixed assets, office rental for sales, marketing and administrative divisions, a provision for doubtful accounts and amortization of intangible assets.

Financial services expenses -

Financial services expenses include a provision for policy reserves and amortization of deferred insurance acquisition costs, and all other operating costs, such as personnel expenses, depreciation of fixed assets, and office rental of subsidiaries, in the Financial Services segment.

Advertising costs -

Advertising costs are expensed when the advertisement or commercial appears in the selected media.

Shipping and handling costs -

The majority of shipping and handling, warehousing and internal transfer costs for finished goods are included in selling, general and administrative expenses. An exception to this is in the Pictures segment where such costs are charged to cost of sales as they are an integral part of producing and distributing motion pictures and television programming. All other costs related to Sony’s distribution network are included in cost of sales, including inbound freight charges, purchasing and receiving costs, inspection costs and warehousing costs for raw materials and

in-process

inventory. Shipping and handling activities that occur after control of the related good transfers are treated as separate performance obligations. Amounts paid by customers for shipping and handling costs are included in net sales.

Income taxes -

The provision for income taxes is computed based on the pretax income included in the consolidated statements of income, and the tax liability attributed to undistributed earnings of subsidiaries and affiliated companies accounted for by the equity method expected to be remitted in the foreseeable future. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities.

Carrying amounts of deferred tax assets require a reduction by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. Management’s judgments related to this assessment consider, among other matters, the nature, frequency and severity of current and cumulative losses on an individual tax jurisdiction basis, forecasts of future profitability after consideration of uncertain tax positions, excess of appreciated asset value over the tax basis of net assets, the duration of statutory carryforward periods, the past utilization of net operating loss carryforwards prior to expiration, as well as prudent and feasible tax planning strategies which would be employed by Sony to prevent net operating loss and tax credit carryforwards from expiring unutilized.

Sony records assets and liabilities for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Sony continues to recognize interest and penalties, if any, with respect to income taxes, including unrecognized tax benefits, as interest expense and as income tax expense, respectively, in the consolidated statements of income. The amount of income taxes Sony pays is subject to ongoing audits by various taxing authorities, which may result in proposed assessments. In addition, several significant items related to intercompany transfer pricing are currently the subject of negotiations between taxing authorities in different jurisdictions as a result of pending advance pricing agreement applications and competent authority requests. Sony’s estimate for the potential outcome for any uncertain tax issues is judgmental and requires significant estimates. Sony assesses its income tax positions and records tax benefits for all years subject to examinations based upon the evaluation of the facts, circumstances and information available at that reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, Sony records the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. If Sony does not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. However, Sony’s future results may include favorable or unfavorable adjustments to Sony’s estimated tax liabilities due to closure of income tax examinations, the outcome of negotiations between taxing authorities in different jurisdictions, new regulatory or judicial pronouncements or other relevant events. As a result, the amount of unrecognized tax benefits, and the effective tax rate, may fluctuate significantly.

The U.S. Tax Cuts and Jobs Act of 2017 (the “U.S. Tax Reform Act”) subjects a U.S. entity to tax on Global Intangible Low Tax Income (“GILTI”) earned by its foreign subsidiaries. Sony has elected to account for GILTI as a current period expense when incurred.

Net income (loss) attributable to Sony Corporation’s stockholders per share (“EPS”) -

Basic EPS is computed based on the weighted-average number of shares of common stock outstanding during each period. The computation of diluted EPS reflects the maximum possible dilution from conversion, exercise, or contingent issuance of securities. All potentially dilutive securities are excluded from the calculation in a situation where there is a net loss attributable to Sony Corporation’s stockholders.

Leases -

In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 

2016-02,

which amends the accounting guidance for leases. The ASU requires substantially all leases to be recognized on the balance sheet. Sony has adopted this ASU effective April 1, 2019, on a modified retrospective basis with no restatement of comparative periods. Sony has elected the package of practical expedients for leases that expired or existed prior to the adoption date. As a result, Sony did not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases, or whether initial direct costs for any existing leases qualify for capitalization. In addition, Sony has applied the short-term lease exception.

As a result of the adoption of this ASU, Sony recognized 316,923 million yen of operating lease

right-of-use

assets and 341,251 million yen of lease liabilities for operating leases on the consolidated balance sheets at April 1, 2019. This impact is mainly due to operating leases of real estate. The difference of 24,328 million yen between

right-of-use

assets and lease liabilities represents deferred rent for leases that existed as of the date of adoption, which was offset against the opening balance of operating lease

right-of-use

assets. Finance lease

 

right-of-use

assets which are included in property, plant and equipment in the consolidated balance sheets for the fiscal year ended March 31, 2019, are now presented as finance lease

right-of-use

assets from April 1, 2019 onward.

Premium amortization on purchased callable debt securities

-

In March 2017, the FASB issued ASU 2017-08, which requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be affected. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position.

Targeted improvements to accounting for hedging activities -

In August 2017, the FASB issued ASU

2017-12,

which made targeted improvements to the accounting for hedging activities. The amendments in this update simplify certain aspects of hedge accounting for both

non-financial

and financial risks and better align the recognition and measurement of hedge results with an entity’s risk management activities. This ASU also amends certain presentation and disclosure requirements for hedging activities and changes how an entity assesses hedge effectiveness. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position.

Measurement of credit losses on financial instruments -

In June 2016, the FASB issued ASU

2016-13,

which amends the accounting guidance for credit losses on financial instruments. The ASU requires the consideration of all available relevant information when estimating expected credit losses, including past events, current conditions and forecasts and their implications for expected credit losses. This ASU is effective for Sony as of April 1, 2020. The adoption of this ASU is not expected to have a material impact on Sony’s results of operations and financial position.

Improvements to Accounting for Costs of Films and License Agreements for Program Materials -

In March 2019, the FASB issued ASU

2019-02,

which updates the guidance for the capitalization of film costs associated with episodic television series, requires the use of fair value rather than net realizable value when determining potential impairments of broadcasting rights, and modifies the presentation and disclosure requirements for films and broadcasting rights. In addition, upon capitalization of film costs entities are required to determine qualitatively whether the predominant monetization strategy is on a

title-by-title

basis or together with other films and/or broadcast rights as part of a film group, such as in the case of a release of a film as part of a library of content on a streaming service. In the case of a film group, impairments are evaluated at the overall film group level rather than the individual title level. This ASU is effective for Sony as of April 1, 2020 and is applied on a prospective basis. Upon adoption, Sony will reclassify

Targeted Improvements to the Accounting for Long-Duration Contracts -

In August 2018, the FASB issued ASU

2018-12,

which revises the accounting for certain long-duration insurance contracts, and in November 2019, the FASB issued ASU

2019-09

to defer the effective date of ASU

2018-12

to January 1, 2022. The ASU prescribes comprehensive changes to recognition and measurement of certain long-duration insurance contracts and assumptions and introduces certain financial statement presentation requirements, as well as significant additional qualitative and quantitative disclosures. This ASU will be effective for Sony as of April 1, 2022. The impact of this ASU on Sony’s results of operations and financial position is being evaluated.

Disclosures for Fair Value Measurement -

In August 2018, the FASB issued ASU

2018-13,

which amends disclosure requirements related to fair value measurement. This ASU is effective for Sony as of April 1, 2020. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position.

Disclosures for Defined Benefit Plans -

In August 2018, the FASB issued ASU

2018-14,

which amends disclosure requirements related to defined benefit pension and other postretirement plans. This ASU is effective for Sony as of April 1, 2020 and will be applied on a retrospective basis. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position.

Income Taxes -

In December 2019, the FASB issued ASU 2019-12, which simplifies the accounting requirements for income taxes. This ASU will be effective for Sony as of April 1, 2021 and amendments within this ASU are required to be applied on a prospective basis, except certain amendments must be applied on a retrospective or modified retrospective basis. The impact of this ASU on Sony’s results of operations and financial position is being evaluated.

Reference Rate Reform -

In March 2020, the FASB issued ASU 2020-04, which provides optional relief for certain contracts impacted by reference rate reform. The relief provided by the amendments is permitted to be adopted any time through December 31, 2022. Sony is still evaluating the impact of reference rate reform and whether to apply the optional relief.

The carrying value of Sony’s investment in M3, Inc. (“M3”)

 

exceeded its proportionate share in the underlying net assets of M3 by 56,140 million yen at March 31, 2020. The excess is substantially attributable to the remeasurement to fair value of the remaining shares of M3, and allocated to identifiable tangible and intangible assets. The intang

ible assets relate primarily to M3’s medical

web-portal.

The unassigned residual value of the excess is recognized as goodwill as a component of the investment balance. The amounts allocated to intangible assets are amortized net of the related tax effects to equity in net income (loss) of affiliated companies over their respective estimated useful lives, principally 10 years, using the straight-line method.

With the exception of M3 as described above, there was no significant difference between Sony’s proportionate share in the underlying net assets of the investees and the carrying value of investments in affiliated companies at March 31, 2019 and 2020.

On December 19, 2019, SRE Holdings Corporation (“SRE”), Sony’s consolidated subsidiary, became a publicly listed company on the Tokyo Stock Exchange Mothers market (the “Listing”). Upon the Listing, Sony sold a portion of its shares of SRE, and shares issued by SRE were publicly offered (collectively, the “Sale”). Sony’s ownership of SRE’s total shares, which was 56.3% before the Sale, has decreased to 44.5% after the Sale. As a result, SRE has become an affiliate accounted for under the equity method of Sony. In connection with the Sale, Sony recorded a gain of 17,266 million yen, which consisted of both a remeasurement gain based on fair value for the shares Sony continues to hold after the Sale, and a realized gain for the sold shares, in other operating (income) loss, net in the consolidated statements of income for the fiscal year ended March 31, 2020.

On January 29, 2020, Sony Life Insurance Co., Ltd.(“Sony Life”), Sony’s consolidated subsidiary, completed the acquisition of the entirety of 50% equity interest held by AEGON International B.V. in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. (collectively, the “JVs”). As a result of this acquisition, the JVs became consolidated subsidiaries of Sony as described in Note 25. AEGON Sony Life Insurance Co., Ltd. has changed its name to “Sony Life With Insurance Co., Ltd.,”

as of

 

April 1, 2020.

 

 

Several affiliated companies are listed on the Tokyo Stock Exchange and Sony’s investments in these companies have an aggregate carrying value and fair value of 141,508 million yen and 756,073 million yen, respectively, as of March 31, 2020.

The number of affiliated companies accounted for under the equity method as of March 31, 2019 and 2020 were 133 and 140, respectively.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

MITSUI-SOKO Supply Chain Solutions, Inc. is accounted for under the equity method and is 34% owned by Sony as a result of the sale of the logistics business on April 1, 2015. As of the fiscal years ended March 31, 2019 and 2020, account balances with MITSUI-SOKO Supply Chain Solutions, Inc. and its subsidiaries were 3,435 million yen and 1,181 million yen, respectively, which are mainly included in accrued expenses. For the fiscal years ended March 31, 2019 and 2020, transactions were 10,606 million yen and 6,069 million yen, respectively, which are mainly included in general and administrative expenses.

Dividends from affiliated companies accounted for under the equity method for the fiscal years ended March 31, 2018, 2019 and 2020 were 5,613 million yen, 4,948 million yen and 4,523 million yen, respectively.

6.	Transfer of financial assets

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Sony has established several accounts receivable sales programs mainly within the EP&S segment. Through these programs, Sony can sell receivables to a commercial bank or a special purpose entity associated with a sponsor bank. Total receivables sold during the fiscal years ended March 31, 2018, 2019 and 2020 were 84,718 million yen, 81,947 million yen and 65,214 million yen, respectively. These transactions are accounted for as sales in accordance with the accounting guidance for transfers of financial assets, because Sony has relinquished control of the receivables. Sony includes the sales proceeds from these receivables as cash flows within operating activities in the consolidated statement of cash flows because the receivables are the result of operating activities and are short term in nature. Gains and losses from these transactions were insignificant. Although Sony continues servicing the receivables subsequent to being sold or contributed, no servicing assets or liabilities are recorded as the costs of collection of the sold receivables and the income from servicing such receivables are insignificant.

Certain accounts receivable sales programs above also involve VIEs. Refer to Note 24.

7.	Marketable securities and securities investments

At March 31, 2020, Sony determined that the decline in value for securities with unrealized losses shown in the above table is not other-than-temporary in nature.

For the

fiscal

 

years

ended March 31, 2019 and 2020, with respect to equity securities included in marketable securities and securities investments, Sony recorded net realized gains of 77,495 million yen and 20,176 million yen due to the sale of equity securities and net unrealized gains of 104,168 million yen and net

 

unrealized

loss of 134,831 million yen due to revaluation of equity securities held as of March 31, 2019 and 2020, respectively. Gains or losses arising from equity securities held in the Financial Services segment are recorded in financial services revenue, and gains or losses arising from equity securities held in all segments other than the Financial Services segment are recorded in gain

 (loss)

on equity securities, net in the consolidated statement of income. Included in the

gains and (losses)

noted above were

gains and (losses)

recorded by Sony with respect to the equity securities held by Sony in Spotify Technology S.A. (“Spotify”).

On April 3, 2018, Spotify was publicly listed for trading on the New York Stock Exchange. Sony owned 5.707% of Spotify’s shares at the time of the public listing.

During the fiscal year ended March 31, 2019, Sony sold a portion of the Spotify shares that it owned for aggregate consideration of 82,616 million yen (768 million U.S. dollars) in cash proceeds. The sale of such shares, offset by costs to be paid to Sony’s artists and distributed labels and other transaction costs which directly related to the gains recognized from the sale of Spotify shares, resulted in a net

pre-tax

realized gain of 54,179 million yen (504 million U.S. dollars) recorded in gain on equity securities, net in the consolidated statement of income. The payments to Sony’s artists and distributed labels are included within Other in the cash flows from investing activities of the consolidated statement of cash flows.

The remaining Spotify shares retained as of March 31, 2019 had a gross fair value of 78,947 million yen (711 million U.S. dollars), and the revaluation of such shares resulted in a

pre-tax

unrealized gain, net of costs to be paid to Sony’s artists and distributed labels and other costs which directly related to the gains recognized from the revaluation of Spotify shares, of 47,543 million yen (449 million U.S. dollars) recorded in gain on equity securities, net in the consolidated statement of income.

During the fiscal year ended March 31, 2020,

Sony did not sell any portion of the Spotify shares that it owned. The

revaluation of the remaining Spotify shares retained as of March 31, 2020 resulted in a

pre-tax

unrealized loss, net of

a decrease in

costs to be paid to Sony’s artists and distributed labels, of 6,063 million yen (57 million U.S. dollars) recorded in loss on equity securities, net in the consolidated statements of income.

Sony realigned its business segments from the first quarter of the fiscal year ended March 31, 2020. As a result of this realignment, the former HE&S, IP&S and MC segments have been realigned as the EP&S segment. In connection with this realignment, the carrying amounts of associated goodwill for the former HE&S, IP&S and MC segments have been reclassified to the EP&S segment for the fiscal years ended March 31, 2018 and 2019. Refer to Note 29.

*

Acquisitions for the fiscal year ended March 31, 2019 relate mainly to the acquisition of EMI Music Publishing in the Music segment. Acquisitions for the fiscal year ended March 31, 2020 relate mainly to the acquisition of Insomniac Games, Inc. in the G&NS segment, Silvergate Media in the Pictures segment and AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. in the Financial Services segment. Refer to Note 25.

 

 

 

10.	Insurance-related accounts

 

 

 

 

 

Sony’s Financial Services segment subsidiaries in Japan maintain their accounting records as described in Note 2 in accordance with the accounting principles and practices generally accepted in Japan, which vary in some respects from U.S. GAAP.

Those differences are mainly that insurance acquisition costs for life and

non-life

insurance contracts are charged to income when incurred in Japan whereas in the United States those costs are deferred and amortized

generally over the premium-paying period of the related insurance policies, and that future policy benefits for life insurance contracts calculated locally under the authorization of the supervisory administrative agencies are comprehensively adjusted using mainly the net level premium method with certain adjustments of actuarial assumptions for U.S. GAAP purposes. For the purpose of preparing the consolidated financial statements, appropriate adjustments have been made to reflect the accounting for these items in accordance with U.S. GAAP.

The combined amounts of statutory net equity of the insurance subsidiaries, which is not measured in accordance with U.S. GAAP, as of March 31, 2019 and 2020 were 548,730 million yen and 586,983 million yen, respectively.

(1)	Insurance policies

 

 

 

 

 

 

 

 

 

 

 

Life insurance policies that subsidiaries in the Financial Services segment underwrite, most of which are categorized as long-duration contracts, mainly consist of whole life, term life and accident and health insurance contracts. The life insurance revenues for the fiscal years ended March 31, 2018, 2019 and 2020 were 857,766 million yen, 910,011 million yen and 1,052,316 million yen, respectively. Property and casualty insurance policies that a subsidiary in the Financial Services segment underwrites are primarily automotive insurance contracts, which are categorized as short-duration contracts. The

non-life

insurance revenues for the fiscal years ended March 31, 2018, 2019 and 2020 were 105,497 million yen, 111,392 million yen and 115,730 million yen, respectively.

(2)	Deferred insurance acquisition costs

 

 

 

 

 

 

 

 

 

 

 

Amortization of deferred insurance acquisition costs charged to income for the fiscal years ended March 31, 2018, 2019 and 2020 amounted to 68,137 million yen, 79,906 million yen and 93,734 million yen, respectively.

At March 31, 2019 and 2020, the balances of deferred insurance acquisition costs of non-traditional life insurance contracts were

209,897 million yen and 206,363 million yen, respectively.

(3)	Future insurance policy benefits

 

 

 

 

 

 

 

 

 

 

 

Liabilities for future

insurance

policy benefits, except the portion of liabilities for minimum guarantee

benefits which is described below, which mainly relate to individual life insurance policies, are established in amounts adequate to meet the estimated future obligations of policies in force. These liabilities, which require significant management judgment and estimates, are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. Future policy benefits are computed using interest rates ranging from 0.5% to 4.5% and are based on factors such as market conditions and expected investment returns. Morbidity, mortality and withdrawal assumptions for all policies are based on either the subsidiary’s own experience or various actuarial tables. Generally these assumptions are

locked-in

throughout the life of the contract upon the issuance of new insurance, although significant changes in experience or assumptions may require Sony to provide for expected future losses. 

Liabilities for future policy benefits includes the liabilities for the minimum guarantee benefits of variable annuities and variable life insurance contracts. The details regarding the minimum guarantee benefits are presented in (5) below. Sony elected the fair value option for certain of these liabilities for future insurance policy benefits. Refer to Note 13.

At March 31, 2019 and 2020, future insurance policy benefits amounted to 5,633,865 million yen and 6,237,048 million yen, respectively.

(4)	Policyholders’ account in the life insurance business

 

 

 

 

 

 

 

 

 

 

 

Policyholders’ account in the life insurance business represents an accumulation of account deposits plus credited interest less withdrawals, expenses and mortality charges. Policyholders’ account includes universal life insurance and investment contracts. Universal life insurance includes interest sensitive whole life contracts and

variable

 

life

insurance

contracts. The credited rates associated with interest sensitive whole life contracts range from 1.7% to 2.0%. For variable

life insurance

 

contracts, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. Investment contracts mainly include single payment endowment contracts, single payment educational endowment contracts, individual variable annuities and policies after the start of annuity payments.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

The credited rates associated with investment contracts, except for individual variable annuities, range from 0.01% to 6.3%. For individual variable annuities, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. The liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business. Refer to Note 13.

Policyholders’ account in the life insurance business is comprised of the following:

		Yen in millions
		March 31
		2019				2020
Universal life insurance			2,104,646				2,611,577
Investment contracts			816,903				885,690

(5)	Minimum guarantee benefit for variable annuities and variable life insurance contracts

 

 

 

 

 

 

 

 

 

 

 

Regarding variable annuities and variable life insurance contracts, minimum guarantee benefits (minimum death benefit, minimum accumulation benefit, etc.) are provided, and Sony bears the risk of fulfilling the minimum guarantee benefits prescribed in the contracts to policyholders. The fair value option is applied to the portion of the liability for variable annuity contracts with minimum guarantee benefits. Refer to Note 13. Excluding the portion of the liability measured at fair value, the liability for the minimum guarantee benefit is calculated based on the ratio of the present value of expected total excess payments divided by the present value of expected total assessments over the life of the contract. Mortality rates, lapse rates, discount rates and investment yield are used as significant assumptions for this calculation.

 

The policyholders’ account value, net amount at risk, liability for the minimum guarantee benefit, and average attained age at March 31, 2019 and 2020 are as follows.

At March 31, 2020, certain subsidiaries in the Financial Services segment pledged marketable securities and securities investments with a book value of 52,942 million yen and housing loans with a book value of 378,241 million yen as collateral for a 200,000 million yen long-term secured loan.

On July 21, 2015, Sony issued 120,000 million yen of 130% callable unsecured zero coupon convertible bonds with stock acquisition rights due 2022 (the “Zero Coupon Convertible Bonds”). The bondholders are entitled to stock acquisition rights effective from September 1, 2015 to September 28, 2022. The initial conversion price was 5,008.0 yen per common share. In addition to the standard anti-dilution provisions, the conversion price is reduced for a certain period before an early redemption triggered upon the occurrence of certain corporate events including a merger, corporate split and delisting event. The reduced amount of the conversion price will be determined by a formula that is based on the effective date of the reduction and Sony’s common stock price. The reduced conversion price ranges from 3,526.5 yen to 5,008.0 yen per common share. The conversion price is also adjusted for dividends in excess of 25 yen per common share per fiscal year. The conversion price has been adjusted to 4,982.5 yen per common share since June 10, 2020 because the payment of the total annual dividend per common share for the fiscal year ended March 31, 2020 was 45 yen, which is in excess of 25 yen. Sony has the option to redeem all of the Zero Coupon Convertible Bonds outstanding at 100% of the principal amount after July 21, 2020, if the closing sales price per share of Sony’s common stock on the Tokyo Stock Exchange is 130% or more of the conversion price of the Zero Coupon Convertible Bonds for 20 consecutive trading days. Sony was not required to bifurcate any of the embedded features contained in the Zero Coupon Convertible Bonds for accounting purposes. There are no significant adverse debt covenants under the Zero Coupon Convertible Bonds.

d

 commercial paper programs totaling 1,044,150 million yen. Sony can issue commercial paper for a period generally not in excess of 270 days up to the size of the programs.

12.	Housing loans and deposits from customers in the banking business

 

 

 

 

 

(1)	Housing loans in the banking business

 

 

 

 

 

Sony acquires and holds certain financial receivables in the normal course of business. The majority of financing receivables held by Sony consists of housing loans in the banking business and no other significant financial receivables exist.

A subsidiary in the banking business monitors the credit quality of housing loans based on the classification set by the financial conditions and the past due status of individual obligors. Past due status is monitored on a daily basis and the aforementioned classification is reviewed on a quarterly basis.

The allowance for the credit losses is established based on the aforementioned classifications and the evaluation of collateral. The amount of housing loans in the banking business and the corresponding allowance for credit losses as of March 31, 2019 were 1,685,504 million yen and 829 million yen, respectively, and as of March 31, 2020 were 1,927,054 million yen and 780 million yen, respectively. During the fiscal years ended March 31, 2019 and 2020, charge-offs on housing loans in the banking business and changes in the allowance for credit losses were not significant.

The balance of housing loans placed on nonaccrual status or past due status were not significant as of March 31, 2019 and 2020.

(2)	Deposits from customers in the banking business

 

 

 

 

 

All deposits from customers in the banking business within the Financial Services segment are interest bearing deposits. At March 31, 2019 and 2020, the balances of time deposits issued in amounts of 10 million yen or more were 292,968 million yen and 306,449 million yen, respectively. These amounts have been classified as current liabilities mainly due to the ability of the customers to make withdrawals prior to maturity.

13.	Fair value measurements

 

 

 

 

 

As discussed in Note 2, assets and liabilities subject to the accounting guidance for fair value measurements held by Sony are classified and accounted for as described below.

(1)	Assets and liabilities that are measured at fair value on a recurring basis

 

 

 

 

 

The following section describes the valuation techniques used by Sony to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified.

Debt securities, equity securities, and other investments

Where quoted prices are available in an active market, securities are classified in level 1 of the fair value hierarchy. Level 1 securities include exchange-traded equities. If quoted market prices are not available for the specific security or the market is inactive, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows and mainly classified in level 2 of the hierarchy. Level 2 securities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, such as the majority of government bonds and corporate bonds. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within level 3 of the fair value hierarchy. Level 3 securities primarily include certain securitized products, certain hybrid financial instruments, certain private equity investments, and certain domestic and foreign corporate bonds not classified within level 1 or level 2.

Derivatives

Exchange-traded derivatives valued using quoted prices are classified within level 1 of the fair value hierarchy. However, few classes of derivative contracts are listed on an exchange; thus, the majority of Sony’s derivative positions are valued using internally developed models that use as their basis readily observable market parameters — i.e., parameters that are actively quoted and can be validated to external sources, including industry pricing services. Depending on the types and contractual terms of derivatives, fair value can be modeled using a series of techniques, such as the Black-Scholes option pricing model, which are consistently applied. Where derivative products have been established for some time, Sony uses models that are widely accepted in the financial services industry. These models reflect the contractual terms of the derivatives, including the period to maturity, and market-based parameters such as interest rates, volatility, and the credit rating of the counterparty. Further, many of these models do not contain a high level of subjectivity as the techniques used in the models do not require significant judgment, and inputs to the model are readily observable from actively quoted markets. Such instruments are generally classified within level 2 of the fair value hierarchy.

In determining the fair value of Sony’s interest rate swap derivatives, Sony uses the present value of expected cash flows based on market observable interest rate yield curves commensurate with the term of each instrument. For foreign currency derivatives, Sony’s approach is to use forward contract and option valuation models employing market observable inputs, such as spot currency rates, time value and option volatilities. These derivatives are classified within level 2 since Sony primarily uses observable inputs in its valuation of its derivative assets and liabilities.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Future insurance policy benefits and policyholders’ account in the life insurance business

In determining the fair value of future insurance policy benefits and policyholders’ account in the life insurance business to which Sony applies the fair value option, Sony uses the present value of future expected cash flows based on mortality rates, lapse rates, discount rates, investment yield and various actuarial assumptions. These are classified within level 3 since Sony primarily uses unobservable inputs in its valuation.

In determining the fair value of liability for the minimum guarantee benefits of variable annuities, Sony uses mortality rates (0.004%~44.865%), lapse rates (1.000

%

~7.500%), and discount rates (-0.061%~1.433%) as significant unobservable inputs. The fair value of the minimum guarante

e

 

accumulation benefits, which is the primary minimum guarantee risk, generally declines with higher mortality rates, higher lapse rates, or higher discount rates.

The fair value of Sony’s assets and liabilities that are measured at fair value on a recurring basis at March 31, 2019 and 2020 are as follows.

assets include certain securitized products, certain private equity investments, and certain domestic and foreign corporate bonds for which quoted prices are not available in a market and where there is less transparency around inputs. In determining the fair value of such assets, Sony uses third-party information such as indicative quotes from dealers without adjustment. Level 3 liabilities include future insurance policy benefits and policyholders’ account in the life insurance business whose underlying figures are unobservable, and whose fair value is calculated in-house. For validating the fair values, Sony primarily uses internal models which include management judgment or estimation of assumptions that market participants would use in pricing the asset.

(2)	Assets and liabilities that are measured at fair value on a nonrecurring basis

 

 

 

Sony also has assets and liabilities that are required to be remeasured to fair value on a nonrecurring basis when certain circumstances occur. During the fiscal years ended March 31, 2019 and 2020, such remeasurements to fair value related primarily to the following:

		During the fiscal year ended March 31, 2019
		Estimated fair value												Amounts included  in earnings
		Level 1				Level 2				Level 3
Assets:
Long-lived assets impairments			—				—				4,389				(44,135	)
Goodwill impairment			—				—				0				(5,107	)
															(49,242	)
		During the fiscal year ended March 31, 2020
		Estimated fair value												Amounts included in earnings
		Level 1				Level 2				Level 3
Assets:
Remeasurement of retained investment in SRE			15,911				—				—				13,347
Long-lived assets impairments			—				—				8,155				(36,003	)
															(22,656	)

 

 

 

Long-lived assets impairments

Sony recorded an impairment loss of 31,341 million yen, 19,172 million yen and 12,714 million yen for the fiscal years ended March 31, 2018, 2019 and 2020, respectively, included within the EP&S segment, related to long-lived assets in the smartphone business asset group. For the smartphone business asset group, the corresponding estimated future cash flows leading to the impairment charge reflected smartphone sales results and expectation of continued difficulty in the business environment.

Sony recorded an impairment loss of 12,858 million yen for the fiscal year ended March 31, 2019, included within All Other, related to long-lived assets and goodwill in the storage media business asset group. As a result of conducting a strategic review of the business and evolving market trends, Sony reduced the corresponding estimated future cash flows of this business and the estimated ability to recover the entire carrying amount of the long-lived assets and goodwill within the period applicable to the impairment determination, resulting in an impairment charge for the fiscal year ended March 31, 2019.

These measurements are classified as level 3 because significant unobservable inputs, such as the condition of the assets or projections of future cash flows, the timing of such cash flows and the discount rate reflecting the risk inherent in future cash flows, were considered in the fair value measurements. For the fiscal year ended March 31, 2018, a discount rate of 8.5% and projected revenue growth rates ranging from (8)% to 6% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2019, a discount rate of 8.5% and projected revenue growth rates ranging from (26)% to 24% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2020, a discount rate of 10.6% and projected revenue growth rates ranging from (10)% to 70% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2019, a discount rate of 8.9% and projected revenue growth rates ranging from (34)% to 21% were used in the fair value measurements related to the long-lived assets and goodwill for the storage media business.

Except as described above, no other impairment losses were individually material for the fiscal year ended March 31, 2020. The other impairment losses were primarily related to the impairment losses in asset groups within Media Networks in the Pictures segment related to a review of the channel portfolio.

Remeasurement of previously owned equity interest in EMI

During the fiscal year ended March 31, 2019, Sony remeasured to fair value the previously owned equity interests in EMI in connection with EMI Music Publishing acquisition. The measurement is classified as level 3 because significant unobservable inputs, such as projections of future cash flows and market comparables of similar transactions and companies were considered in the fair value measurements. Refer to Note 25.

Remeasurement of retained investment in SRE

During the fiscal year ended March 31, 2020, Sony sold part of its shares in SRE and remeasured the remaining shares to fair value. This measurement is classified as level 1 because a quoted price for the shares of SRE is available on the Tokyo Stock Exchange. Refer to Note 5.

Remeasurement of previously owned equity interest in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd.

During the fiscal year ended March 31, 2020, Sony remeasured to fair value the previously owned equity interests in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. (collectively, the “JVs”) in connection with acquisition of the JVs. The measurement is classified as level 3 because significant unobservable inputs, such as projections of future cash flows and market comparables of similar transactions and companies, were considered in the fair value measurements. AEGON Sony Life Insurance Co., Ltd. changed its name to “Sony Life With Insurance Co., Ltd.,” as of April 1, 2020. Refer to Note 25.

(3)	Financial instruments

The estimated fair values by fair value hierarchy level of certain financial instruments that are not reported at fair value are summarized as follows:

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

The summary excludes cash and cash equivalents, call loans, time deposits, notes and accounts receivable, trade, call money, short-term borrowings, notes and accounts payable, trade and deposits from customers in the banking business because the carrying values of these financial instruments approximated their fair values due to their short-term nature. The summary also excludes

held-to-maturity

securities disclosed in Note 7.

Cash and cash equivalents, call loans and call money are classified in level 1. Time deposits, short-term borrowings, deposits from customers in the banking business are classified in level 2.

Held-to-maturity

securities, included in marketable securities and securities investments and other in the consolidated balance sheets, primarily include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, such as the majority of government bonds and corporate bonds and are substantially all classified in level 2. The fair values of housing loans in the banking business, included in securities investments and other in the consolidated balance sheets, were estimated based on the discounted future cash flows using interest rates reflecting London Interbank Offered Rate base yield curves with certain risk premiums. The fair values of long-term debt including the current portion and investment contracts included in policyholders’ account in the life insurance business were estimated based on either the market value or the discounted future cash flows using Sony’s current incremental borrowing rates for similar liabilities.

14.	Derivative instruments and hedging activities

 

 

 

 

Sony has certain financial instruments including financial assets and liabilities acquired in the normal course of business. Such financial instruments are exposed to market risk arising from the changes in foreign currency exchange rates and interest rates. In applying a consistent risk management strategy for the purpose of reducing such risk, Sony uses derivative financial instruments, which include foreign exchange forward contracts, foreign currency option contracts, and interest rate swap agreements (including interest rate and currency swap agreements). Certain other derivative financial instruments are entered into in the Financial Services segment for asset-liability management (“ALM”) purposes. These instruments are executed with creditworthy financial institutions, and virtually all foreign currency contracts are denominated in U.S. dollars, euros and other currencies of major countries. These derivatives generally mature or expire within six months after the balance sheet date. Other than derivatives utilized in the Financial Services segment for ALM, Sony does not use derivative financial instruments for trading or speculative purposes. These derivative transactions utilized for ALM in the Financial Services segment are executed within certain limits in accordance with an internal risk management policy.

Derivative financial instruments held by Sony are classified and accounted for as described below.

Fair value hedges

Both the derivatives designated as fair value hedges and the hedged items are reflected at fair value in the consolidated balance sheets. Changes in the fair value of the derivatives designated as fair value hedges, as well as offsetting changes in the carrying value of the underlying hedged items, are recognized in income. For the fiscal years ended March 31, 2018

,

2

019

and

20

20

, there were no amounts excluded from the assessment of hedge effectiveness of fair value hedges.

Cash flow hedges

Changes in the fair value of derivatives designated as cash flow hedges are initially recorded in other comprehensive income (“OCI”) and reclassified into earnings when the hedged transaction affects earnings. The time value component of the fair value of option contracts is excluded from the assessment of hedge effectiveness and recognized in earnings on a straight-line basis over the life of the hedging instruments. Any difference between the change in fair value of the excluded component and

the

accumulated amount recognized in earnings on a straight-line basis

 

is recognized in OCI.

Derivatives not designated as hedges

Changes in the fair value of derivatives not designated as hedges are recognized in income.

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

A description of the purpose and classification of the derivative financial instruments held by Sony is as follows:

Foreign exchange forward contracts and foreign currency option contracts

Foreign exchange forward contracts and purchased and written foreign currency option contracts are utilized primarily to limit the exposure affected by changes in foreign currency exchange rates on cash flows generated or anticipated by Sony’s transactions and accounts receivable and payable denominated in foreign currencies. The majority of written foreign currency option contracts are a part of range forward contract arrangements and expire in the same month with the corresponding purchased foreign currency option contracts.

Sony also entered into foreign exchange forward contracts and foreign exchange range forward contracts which effectively fixed the cash flows from certain forecasted purchase and sale transactions denominated in foreign currencies for the fiscal years ended March 31,

 

2018

, 2019

and 20

20

. Accordingly, these derivatives have been designated as cash flow hedges.

Foreign exchange forward contracts and foreign currency option contracts that do not qualify as hedges are

marked-to-market

with changes in value recognized in other income and expenses.

Foreign exchange forward contracts, foreign currency option contracts and currency swap agreements held by certain subsidiaries in the Financial Services segment are

marked-to-market

with changes in value recognized in financial services revenue.

Interest rate swap agreements (including interest rate and currency swap agreements)

Interest rate swap agreements are utilized primarily to lower funding costs, to diversify sources of funding and to limit Sony’s exposure associated with underlying borrowings and

available-for-sale

debt securities resulting from adverse fluctuations in interest rates, foreign currency exchange rates and changes in fair values.

Interest rate swap agreements entered into in the Financial Services segment are used for reducing the risk arising from the changes in the fair value of fixed rate

available-for-sale

debt securities. These derivatives are considered to be a hedge against changes in the fair value of

available-for-sale

debt securities in the Financial Services segment. Accordingly, these derivatives have been designated as fair value hedges.

Certain subsidiaries in the Financial Services segment have interest rate swap agreements as part of their ALM, which are

marked-to-market

with changes in value recognized in financial service revenues.

Any other interest rate swap agreements that do not qualify as hedges, which are used for reducing the risk arising from changes of variable rate debt, are

marked-to-market

with changes in value recognized in other income and expenses.

Other agreements

Certain subsidiaries in the Financial Services segment have equity future contracts, equity swap agreements, bond future contracts, commodity future contracts, interest rate swaption agreements, other currency contracts and hybrid financial instruments as part of their ALM, which are

marked-to-market

with changes in value recognized in financial services revenue. The hybrid financial instruments, disclosed in Note 7 as debt securities, contained embedded derivatives that are not required to be bifurcated because the entire instruments are carried at fair value.

All derivatives are recognized as either assets or liabilities in the consolidated balance sheets on a gross basis, but certain subsidiaries have entered into master netting agreements or other similar agreements, which are mainly International Swaps and Derivatives Association (ISDA) Master Agreements. An ISDA Master Agreement is an agreement between two counterparties that may have multiple derivative contracts with each other, and such ISDA Master Agreement may provide for the net settlement of all or a specified group of these derivative contracts, through a single payment, in a single currency, in the event of a default on or affecting any one derivative contract, or a termination event affecting all or a specified group of derivative contracts. Presented below are the effects of offsetting derivative assets, derivative liabilities, financial assets and financial liabilities as of March 31, 2019 and 2020.

15.	Pension and severance plans

 

 

 

 

(1)	Defined benefit and severance plans

 

 

 

 

Upon terminating employment, employees of Sony Corporation and its subsidiaries in Japan are entitled, under most circumstances, to

lump-sum

indemnities or pension payments as described below. Sony Corporation and certain of its subsidiaries’ pension plans utilize a point-based plan under which a point is added every year reflecting the individual employee’s performance over that year. Under the point-based plan, the amount of payment is determined based on the sum of cumulative points from past services and interest points earned on the cumulative points regardless of whether or not the employee is voluntarily retiring.

Under the plans, in general, the defined benefits cover 65% of the indemnities under existing regulations to employees. The remaining indemnities are covered by severance payments by the companies. The pension benefits are payable at the option of the retiring employee either in a

lump-sum

amount or monthly pension payments. Contributions to the plans are funded through several financial institutions in accordance with the applicable laws and regulations.

From April 1, 2012, Sony Corporation and substantially all of its subsidiaries in Japan have modified existing defined benefit pension plans such that life annuities will no longer accrue additional service benefits, with those participants instead accruing fixed-term annuities. The defined benefit pension plans were closed to new participants and a defined contribution plan was also introduced.

From October 1, 2019, Sony Corporation and substantially all of its subsidiaries in Japan have amended their defined benefit pension plans and have implemented defined contribution plans for all employees other than those employees that had retired before the amendments. As a result, accrued pension and severance costs decreased 74,872 million yen and accumulated other comprehensive income increased 81,230 million yen in the consolidated balance sheets as of the fiscal year ended March 31, 2020. In addition, a loss on the pension plan amendment of 6,358 million yen was recorded in other expenses in the consolidated statements of income for the fiscal year ended March 31, 2020.

In addition, several of Sony’s foreign subsidiaries have defined benefit pension plans or severance indemnity plans, which cover substantially all of their employees. Under such plans, the related cost of benefits is currently funded or accrued. Benefits awarded under these plans are based primarily on the current rate of pay and length of service.

Weighted-average assumptions used to determine the net periodic benefit costs for the fiscal years ended March 31, 2018, 2019 and 2020 were as follows:

		Japanese plans												Foreign plans
		Fiscal year ended March 31												Fiscal year ended March 31

Expected return on plan assets			2.4				2.6				2.6				4.6				4.4				4.2
Rate of compensation increase			*				*				*				2.4				2.6				2.3

 

 

 

* Substantially all of Sony’s Japanese pension plans were point-based. Point-based plans do not incorporate a measure of compensation rate increases.

Sony reviews these assumptions for changes in circumstances.

The weighted-average rate of compensation increase is calculated based only on the

pay-related

plans. The point-based plans discussed above are excluded from the calculation because payments made under the plan are not based on employee compensation.

The mortality rate assumptions are based on life expectancy and death rates for different types of participants.

To determine the expected long-term rate of return on pension plan assets, Sony considers the current and expected asset allocations, as well as the historical and expected long-term rates of returns on various categories of plan assets. Sony’s pension investment policy recognizes the expected growth and the variability risk associated with the long-term nature of pension liabilities, the returns and risks of diversification across asset classes, and the correlation among assets. The asset allocations are designed to maximize returns consistent with

F-5

Table of Contents

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

levels of liquidity and investment risk that are considered prudent and reasonable. While the pension investment policy gives appropriate consideration to recent market performance and historical returns, the investment assumptions utilized by Sony are designed to achieve a long-term return consistent with the long-term nature of the corresponding pension liabilities.

The investment objectives of Sony’s plan assets are designed to generate returns that will enable the plans to meet their future obligations. The precise amount for which these obligations will be settled depends on future events, including the retirement dates and life expectancy of the plans’ participants. The obligations are estimated using actuarial assumptions, based on the current economic environment and other pertinent factors. Sony’s investment strategy balances the requirement to generate returns, using potentially higher yielding assets such as equity securities, with the need to control risk in the portfolio with less volatile assets, such as fixed-income securities. Risks include, among others, inflation, volatility in equity values and changes in interest rates that could negatively impact the funding level of the plans, thereby increasing its dependence on contributions from Sony. To mitigate any potential concentration risk, thorough consideration is given to balancing the portfolio among industry sectors and geographies, taking into account interest rate sensitivity, dependence on economic growth, currency and other factors that affect investment returns. The target allocations as of March 31, 2020, are, as a result of Sony’s asset liability management, 17% of equity securities, 54% of fixed income securities and 29% of other investments for the pension plans of Sony Corporation and most of its subsidiaries in Japan, and, on a weighted average basis, 14% of equity securities, 63% of fixed income securities and 23% of other investments for the pension plans of foreign subsidiaries.

The fair values of the assets held by Japanese and foreign plans, which are classified in accordance with the fair value hierarchy described in Note 2, are as follows:

Each level in the fair value hierarchy in which each plan asset is classified is determined based on inputs used to measure the fair values of the asset, and does not necessarily indicate the risks or rating of the asset.

The following is a description of the valuation techniques used to measure Japanese and foreign plan assets at fair value. The valuation techniques are applied consistently from period to period.

Equity securities are valued at the closing price reported in the active market in which the individual securities are traded. These assets are generally classified as level 1.

The fair value of fixed income securities is typically estimated using pricing models, quoted prices of securities with similar characteristics or discounted cash flows and are generally classified as level 2.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

Commingled funds are typically measured using the valuation provided by the administrator of the fund and reviewed by Sony. The valuation is based on Sony’s interest in the value of the underlying assets owned by the fund minus liabilities. These assets are classified as level 1, level 2 or level 3 depending on availability of quoted market prices.

Commodity funds are valued using inputs that are derived principally from or corroborated by observable market data. These assets are generally classified as level 2.

Private equity and private real estate investment trust valuations require significant judgment due to the absence of quoted market prices, the inherent lack of liquidity and the long-term nature of such assets. These assets are initially valued at cost and are reviewed periodically utilizing available and relevant market data to determine if the carrying value of these assets should be adjusted. These investments are classified as level 3.

Hedge funds are measured using the valuation provided by the administrator or custodian of the fund and reviewed by Sony. The valuation is based on Sony’s interest in the value of the underlying assets owned by the fund minus liabilities. These investments are classified as level 3.

The following table sets forth a summary of changes in the fair values of Japanese and foreign plans’ level 3 assets for the fiscal years ended March 31, 2019 and 2020:

Sony has a stock-based compensation incentive plan for selected directors, corporate executive officers and employees in the form of a stock acquisition rights plan. The stock acquisition rights generally have three year graded vesting schedules and are exercisable up to ten years from the date of grant.

The total cash received from exercises under all of the stock acquisition rights plans during the fiscal years ended March 31, 2018, 2019 and 2020 was 7,129 million yen, 12,757 million yen and 7,560 million yen, respectively. Sony issued new shares of common stock upon exercise of these rights.

The fair value of stock acquisition rights granted on the date of grant and used to recognize compensation expense for the fiscal years ended March 31, 2018, 2019 and 2020 was estimated using the Black-Scholes option-pricing model with the following weighted-average assumptions:

		Fiscal year ended March 31
		2018				2019				2020
Weighted-average assumptions
Risk-free interest rate			1.14	%			1.37	%			0.70	%
Expected lives			6.55	years			5.98	years			5.73	years
Expected volatility *			38.49	%			32.52	%			29.30	%
Expected dividends			0.40	%			0.35	%			0.32	%

 

 

 

 

 

 

 

*

Expected volatility was based on the historical volatilities of Sony Corporation’s common stock over the expected life of the stock acquisition rights.

 

 

 

 

 

 

 

A summary of the activities regarding the stock acquisition rights plan during the fiscal year ended March 31, 2020 is as follows:

		Fiscal year ended March 31, 2020
		Number of shares				Weighted- average exercise price				Weighted- average remaining life				Total intrinsic value
						Yen				Years				Yen in millions
Outstanding at beginning of the fiscal year			12,213,900				3,665

18.	Kumamoto Earthquake

 

 

 

 

 

 

In April 2016, a series of earthquakes occurred in the Kumamoto region of Japan. These earthquakes caused damage to certain fixed assets, including buildings, machinery and equipment, as well as inventories in manufacturing sites located in the Kumamoto region.

For the fiscal year ended March 31, 2017, Sony incurred incremental losses and associated expenses including repair costs of fixed assets and a loss on disposal of inventories directly related to the damage caused by the earthquakes of 16,682 million yen. These losses and expenses were primarily recorded in cost of sales in the consolidated statements of income and were offset by insurance recoveries of 10,682 million yen, as described below. In addition, Sony incurred other expenses of 9,365 million yen, which included idle facility costs at manufacturing sites. These expenses were primarily recorded in cost of sales in the consolidated statements of income.

Sony has insurance policies that cover certain damage directly caused by the earthquakes for Sony Corporation and certain of its subsidiaries, including damage at manufacturing sites. The insurance policies cover the damage and costs associated with fixed assets and inventories, as well as incremental expenses including removal and cleaning costs. These policies also provide business interruption coverage, including coverage for lost profits. For the fiscal year ended March 31, 2017, Sony recorded insurance receivables of 10,682 million yen, representing a portion of the insurance recoveries that were deemed probable of collection up to the extent of the amount of corresponding losses recognized in the same period. Of the insurance receivables recorded during the period, substantially all relate to damaged assets and inventories, and do not include amounts for business interruption or lost profits. Sony concluded that the recoveries from insurance claims are probable based on the coverage under valid policies, communications with the insurance carriers, Sony’s past claims history with the insurance carriers, and Sony’s assessment that the insurance carriers have the financial ability to pay the claims. In March 2017, 10,000 million yen was agreed to by the insurance carriers. These receivables are recorded within other receivables, whereas the remaining receivables of 682 million yen is recorded in other current assets in the consolidated balance sheets as of the fiscal year ended March 31, 2017.

Sony has underwritten 2,000 million yen in reinsurance policies for the above insurance carriers related to the policy described above. The amount was recorded in other current liabilities in the consolidated balance sheets as of the fiscal year ended March 31, 2017 and was paid to the insurance carriers in the fiscal year ended March 31, 2018.

In April 2017, the remaining insurance claims of 10,000 million yen that were mainly for business interruption coverage were agreed to by the carriers. As a result, the total amount of insurance recoveries paid to Sony in April 2017 was 20,000 million yen. 9,318 million yen, which was the difference between 20,000 million yen and 10,682 million yen as described above, was recorded in other operating revenue for the fiscal year ended March 31, 2018. The proceeds from insurance recoveries were presented as cash flows from operating activities in the consolidated statements of cash flows for the fiscal year ended March 31, 2018.

*2

Contract liabilities are included in the consolidated balance sheets as “Other”, both current and non-current.

 

 

 

 

 

 

Contract liabilities principally relate to customer advances received prior to performance. Revenues of 204,265 million yen were recognized during the fiscal year ended March 31, 2020, which were included in the balance of contract liabilities at

March 31

, 2019. Revenues of 61,706 million yen were recognized during the fiscal year ended March 31, 2020 from performance obligations satisfied prior to March 31, 2019.

(2)	Performance obligations

 

 

 

 

 

 

Remaining (unsatisfied or partially unsatisfied) performance obligations represent future revenues not yet recorded for firm orders that have not yet been performed. Sony applies practical expedients to exclude certain information about the remaining performance obligations, primarily related to contracts with an expected original duration of less than one year, and sales-based or usage-based royalty revenue on licenses of intellectual property. The following table shows the summary of the transaction prices allocated to remaining performance obligations that are unsatisfied at March 31, 2020, of which more than half are expected to be recognized within one year and substantially all within three years.

		Yen in millions
		March 31, 2020
Pictures — Motion Pictures and Television Productions *1			569,081
Pictures — Media Networks			22,333
Music *2			44,971
Others			47,126

 

 

 

 

 

 

*1

For Motion Pictures and Television Productions in the Pictures segment, Sony has included all contracts regardless of duration.

 

 

 

 

 

 

*2

Amount included in the Music segment primarily consists of minimum royalty guarantees or fixed fees in contracts related to license revenue for ongoing access to an evolving library of content. These contracts also include the potential for sales-based or usage-based royalties to exceed the minimum guarantees, and these additional royalties are excluded from the amount above, of which substantially all are recognized as revenue within three years.

 

 

 

 

 

 

(3)	Contract costs

Contract costs are comprised as follows:

		Yen in millions
		March 31 , 2019				March 31, 2020
Incremental costs of obtaining a contract			6,581				7,464

 

 

 

 

 

 

Sony applies practical expedients to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset that otherwise would have been recognized is one year or less. The amortization of 6,420 million yen was recognized during the fiscal year ended March 31, 2020. The incremental costs of obtaining a contract are primarily recognized in the EP&S segment for the internet-related service business and amortized to expense over the contract period.

(4)	Disaggregation of revenue

 

 

 

 

 

 

For the breakdown of sales and operating revenue by segments, product categories and geographies, refer to Note 29.

20.	Restructuring charges

 

 

 

 

 

 

As part of its effort to improve the performance of the various businesses, Sony has undertaken a number of restructuring initiatives. Sony defines restructuring initiatives as activities initiated by Sony, which are designed

to generate a positive impact on future profitability. These activities include exiting a business or product category, implementing a headcount reduction program, realignment of its manufacturing sites to

low-cost

areas, utilizing the services of third-party original equipment and design manufacturers (OEMs and ODMs), a review of its development and design structure, and the streamlining of its sales and administrative functions. The restructuring activities are generally short term in nature and are generally completed within one year of initiation.

The changes in the accrued restructuring charges for the fiscal years ended March 31, 2018, 2019 and 2020 are as follows:

Depreciation associated with restructured assets as used in the context of the disclosures regarding restructuring activities refers to the increase in depreciation expense caused by revising the useful life and the salvage value of depreciable fixed assets under an approved restructuring plan. Any impairment of the assets is recognized immediately in the period it is identified.

Retirement programs

Sony has undergone several headcount reduction programs to further reduce operating costs primarily in an effort to improve the performance of certain segments related to the EP&S segment and reduce cost at the headquarters function. Through measures including the realignment of its manufacturing sites, a review of its development and design structure, and the streamlining of its sales and administrative functions, Sony has continued to implement a company-wide (including headquarters) rationalization. Sony intends to reallocate and optimize its workforce through programs including work reassignments and outplacements. The employee termination benefits costs in the above table are included in selling, general and administrative in the consolidated statements of income.

Music

In an effort to optimize the organization and improve the performance of the Music segment, Sony has implemented a number of restructuring initiatives targeting operating effectiveness and cost reduction. These activities resulted in restructuring charges primarily consisting of headcount reductions totaling 6,630 million yen, 3,192 million yen and 3,185 million yen for the fiscal years ended March 31, 2018, 2019 and 2020

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

On December 22, 2017, the U.S. Tax Reform Act was signed into law, making significant changes to the U.S. tax rules. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning January 1, 2018 and the transition of U.S. international taxation from a worldwide tax system to a modified territorial system, with a

one-time

mandatory transition tax on previously deferred foreign earnings of U.S. subsidiaries.

In addition to lowering the statutory corporate tax rate from 35% to 21%, the U.S. Tax Reform Act also eliminated certain deductions, included new restrictions on the deduction for interest, introduced a new tax regime called the Base Erosion Anti-Abuse Tax or “BEAT”, and changed how foreign earnings of the U.S. group are subject to tax. The U.S. Tax Reform Act also enhanced and extended the option to claim accelerated depreciation and amortization deductions by allowing full expensing of qualified property, including film costs, through 2022. The U.S. Tax Reform Act also provided for beneficial treatment of certain income derived by a U.S. entity from outside the United States (referred to as Foreign Derived Intangible Income or “FDII”).

The BEAT creates a minimum tax on multinational corporations by requiring companies subject to the BEAT to pay the greater of their regular tax liability (less certain credits, including foreign tax credits) or 10% for taxable years beginning in 2019 (6.25% for

the

 fiscal year ended March 31. 2019) of a modified tax base which adds back certain related party payments. The BEAT comparison to regular tax must be done each year if the taxpayer’s “base erosion” related party payments exceed 3% of total deductions on its U.S. tax return. The U

.

S

.

Treasury Department issued regulations which allow taxpayers to elect to forego deductions in order to stay below the 3% threshold. Sony initially expected to exceed the 3% threshold for the fiscal year ended March 31, 2019, but upon further detailed analysis at the time of the tax return filing, determined that it would be below the 3% threshold and therefore could use foreign tax credits to offset its regular tax liability. Sony believes it will be below the 3% threshold for the fiscal year ended March 31, 2020, and if not, would be able to avail itself of the election in the regulations that allows it to forego deductions to come under the threshold. Accordingly, Sony has provided for its taxes assuming the U

.

S

.

regular tax liability

is

offset by tax credits. Sony is required to determine if it is subject to the BEAT on an annual basis,

to

account for

th

e

BEAT as a period cost and to record deferred taxes at the regular statutory rate. Accordingly, Sony has recorded its U.S. deferred tax assets and liabilities at 21%.

Sony provides a valuation allowance for its deferred tax assets, which includes net operating losses, temporary differences and tax credits, when it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in the relevant tax jurisdiction. As of December 31, 2018, SAHI and its U.S. consolidated tax filing group has continued its profitable trend, primarily as a result of the G&NS segment and the Music segment. Based on an assessment of the available positive and negative evidence, in the quarter ended December 31, 2018, Sony reversed the valuation allowances

established

against a significant portion of the deferred tax assets in the United States, primarily for net operating losses, temporary differences and certain tax credits, and recorded a tax benefit of 154,201 million yen.

Based on the weight of the available positive and negative evidence, for the fiscal year ended March 31, 2020, Sony continued to maintain valuation allowances against the deferred tax assets at Sony Corporation and its national tax filing group in Japan, as well as at Sony Mobile Communications in Sweden, Sony Europe B.V. in the United Kingdom, certain subsidiaries in Brazil, and certain subsidiaries in other tax jurisdictions. Valuation allowances also continue to be established on the remaining U.S. deferred tax assets, primarily foreign tax credits and certain research and development credits. Sony Corporation and its national tax filing group in Japan established

a

valuation allowance

 

of 274,761 

million yen relating to national

 tax and 125,465 million

yen relating to local tax.

For the deferred tax assets related to national tax in Sony Corporation and its national tax filing group in Japan, the valuation allowance is still established except for the amounts expected to be offset with taxable temporary differences as of March 31, 2020.

Due to the uncertainty of the forecast of future income impacted by the spread of COVID-19 from early 2020, the valuation allowance established against the net deferred tax assets that are attributable to Sony Corporation and its national tax filing group in Japan was not reversed, even partially, in the fiscal year ended March 31, 2020 despite several years of profitability.

The net changes in the total valuation allowance were decreases of 152,129 million yen, 176,721 million yen and 114,871 million yen for the fiscal years ended March 31, 2018, 2019 and 2020, respectively.

The decrease in the valuation allowances during the fiscal year ended March 31, 2018 was primarily due to the use of net operating loss carryforwards and other deferred tax assets for both the national tax filing group in Japan and the consolidated tax filing group in the United States. The U.S. deferred tax assets were also reduced as a result of the reduction in the tax rate under the U.S. Tax Reform Act which had a corresponding reduction of the valuation allowance on those assets. In addition, valuation allowances were reversed in several jurisdictions, including France and Canada, as a result of sustained profitability.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

The decrease in the valuation allowances during the fiscal year ended March 31, 2019 was due to the reversal of the valuation allowances on significant deferred tax assets in SAHI and its U.S. consolidated tax filing group and the use of net operating loss carryforwards and other deferred tax assets in the national tax filing group in Japan and other jurisdictions.

The decrease in the valuation allowances during the fiscal year ended March 31, 2020 was due to the use of net operating loss carryforwards and other deferred tax assets in the national tax filing group in Japan and the use of foreign tax credits and certain research and development credits in the consolidated tax filing group in the United States.

At March 31, 2020, 16,312 million yen of deferred income taxes have not been provided on undistributed earnings of certain foreign subsidiaries and corporate joint ventures not expected to be remitted in the foreseeable future totaling 1,019,525 million yen. In addition, deferred income taxes have not been provided on the gain on the book/tax basis difference in subsidiaries, including a gain of 61,544 million yen on a subsidiary’s sale of stock arising from the issuance of common stock of Sony Music Entertainment (Japan) Inc. in a public offering to third parties in November 1991 and the remeasurement gain for the equity interest in EMI (Refer to Note 25). Sony does not anticipate any significant tax consequences on the possible future disposition of these investments based on its tax planning strategies.

At March 31, 2020, Sony had net operating loss carryforwards, the tax effect of which totaled 348,714 million yen, which may be available as an offset against future taxable income on tax returns to be filed in various tax jurisdictions. With the exception of 96,890 million yen with no expiration period, substantially all of the total net operating loss carryforwards expire at various dates between the fiscal years ending March 31, 2021 and 2024.

Tax credit carryforwards at March 31, 2020 amounted to 94,900 million yen. With the exception of 15,059 million yen with no expiration period, substantially all of the total available tax credit carryforwards expire at various dates between the fiscal years ending March 31, 2021 and 2030.

A reconciliation of the beginning and ending gross amounts of unrecognized tax benefits is as follows:

		Yen in millions

Total net amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate			39,308				35,004				29,539

 

 

 

The major changes in the total gross amount of unrecognized tax benefit balances relate to transfer pricing adjustments, including as a result of the Bilateral Advance Pricing Agreements (“APAs”) and competent authority requests filed for certain subsidiaries in the G&NS, EP&S and I&SS segments and All Other, with respect to the intercompany cross-border transactions. The APAs include agreements between Sony and two taxing authorities under the authority of the mutual agreement procedure specified in income tax treaties. Sony reviews its estimated tax expense based on the progress made in these procedures, and the progress of transfer pricing audits generally, and makes adjustments to its estimates as necessary. In addition, the APAs are government to government negotiations, and therefore it is possible that the final outcomes of the agreements may differ from Sony’s current assessment of the

more-likely-than-not

outcomes of such agreements.

During the fiscal year ended March 31, 2018, Sony recorded 1,053 million yen of interest expense and 876 million yen of penalties. At March 31, 2018, Sony had recorded liabilities of 10,788 million yen and 4,637 million yen for the payments of interest and penalties, respectively.

SONY CORPORATION AND CONSOLIDATED SUBSIDIARIES

During the fiscal year ended March 31, 2019, Sony reversed 1,479 million yen of interest expense and recorded 218 million yen of penalties. At March 31, 2019, Sony had recorded liabilities of 9,309 million yen and 4,855 million yen for the payments of interest and penalties, respectively.

During the fiscal year ended March 31, 2020, Sony re

versed

 1,276 million yen of interest expense and re

corded

 117 million yen of penalties. At March 31, 2020, Sony had recorded liabilities of 8,033 million yen and 4,971 million yen for the payments of interest and penalties, respectively.

Sony operates in multiple jurisdictions throughout the world, and its tax returns are periodically audited by Japanese and foreign taxing authorities. As a result of audit settlements, the conclusion of current examinations, the expiration of the statute of limitations in several jurisdictions and other reevaluations of Sony’s tax positions, it is expected that the amount of unrecognized tax benefits will change in the next twelve months. Accordingly, Sony believes it is reasonably possible that its existing unrecognized tax benefits may be reduced by an amount up to 1,791 million yen within the next twelve months.

Sony remains subject to examinations by Japanese taxing authorities for tax years from 2010 through 2019, and by the U.S. tax authorities for tax years from

2016 through 2019 and other material foreign taxing authorities for tax years from 2006 through 2019.

23.	Reconciliation of the differences between basic and diluted EPS

Reconciliation of the differences between basic and diluted EPS for the fiscal years ended March 31, 2018, 2019 and 2020 is as follows:

		Yen in millions
		Fiscal year ended March 31
		2018				2019				2020
Net income attributable to Sony Corporation’s stockholders for basic and diluted EPS computation			490,794				916,271				582,191
		Thousands of shares
Weighted-average shares outstanding			1,263,895				1,266,592				1,234,408
Effect of dilutive securities:
Stock acquisition rights			4,565				4,088				3,853
Zero coupon convertible bonds			23,960				23,966				23,994
Weighted-average shares for diluted EPS computation			1,292,420				1,294,646				1,262,255
		Yen
Basic EPS			388.32				723.41				471.64
Diluted EPS			379.75				707.74				461.23

 

 

 

Potential shares of common stock which were excluded from the computation of diluted EPS for the fiscal years ended March 31, 2018, 2019 and 2020 were 2,921 thousand shares, 5,731 thousand shares and 3,212 thousand shares, respectively. Potential shares related to stock acquisition rights were excluded as anti-dilutive for the fiscal years ended March 31, 2018, 2019 and 2020 when the exercise price for those shares was in excess of the average market value of Sony’s common stock for those fiscal years. The zero coupon convertible bonds issued in July 2015 were included in the diluted EPS calculation under the

if-converted

method beginning upon issuance.

24.	Variable interest entities

 

 

 

Sony has entered into various arrangements with VIEs.

(1 )	Consolidated VIEs

 

 

 

Sony’s U.S. subsidiary that is engaged in the recorded music business has entered into several joint ventures with companies involved in the production and creation of recorded music. Sony has reviewed these joint

ventures and determined that they are VIEs. Based on a qualitative assessment, it was determined that Sony has the power to direct the activities that most significantly impact the VIEs’ economic performance, as well as the obligation to absorb the losses of these VIEs as Sony is responsible for providing funding to these VIEs, and in most cases absorbs all losses until the VIEs become profitable. As a result, it has been determined that Sony is the primary beneficiary and, accordingly, these VIEs are consolidated by Sony. The assets of Sony are not available to settle the obligations of these VIEs. As of March 31, 2020, the total assets and liabilities for these VIEs, on an aggregate basis, were 46,154 million yen and 25,100 million yen, respectively.

(2)	Unconsolidated VIEs

 

 

 

 

 

 

As described in Note 6, certain accounts receivable sales programs also involve VIEs. These VIEs are all special purpose entities associated with the sponsor banks. Based on a qualitative assessment, Sony is not the primary beneficiary and therefore does not consolidate these entities as Sony does not have the power to direct the activities, an obligation to absorb losses, or the right to receive the residual returns of these VIEs. Sony’s maximum exposure to losses from these VIEs is considered insignificant.

In the Financial Services segment, Sony has variable interests in VIEs where Sony is not the primary beneficiary. Sony’s variable interests in such VIEs include equity securities, securitized products, foreign corporate bonds and other investments.

The following tables present the carrying value of the variable interests of unconsolidated VIEs, the presentation in the consolidated balance sheet, and the maximum exposure to loss associated with these variable interests as of March 31, 2019 and 2020. Maximum exposure to loss does not reflect Sony’s estimate of the actual losses that could result from adverse changes, nor does it reflect the economic hedges Sony enters into to reduce its exposure. The risks associated with VIEs in which Sony is involved are limited to the amount recorded in the consolidated balance sheets and the amount of commitments.

25.	Acquisitions

 

 

 

 

 

 

(1)	EMI Music Publishing acquisition

 

 

 

 

 

 

On November 14, 2018, Sony Corporation of America, Sony’s wholly-owned subsidiary, completed the acquisition of the entirety of the approximately 60% equity interest held by the investor consortium led by the Mubadala Investment Company in DH Publishing, L.P. (“EMI”), which owned and managed EMI Music Publishing, for the equity purchase price of 257,168 million yen (2,269 million U.S. dollars), which includes payments related to warrants and management equity plans. Sony paid all the consideration in cash upon the acquisition. As a result of this acquisition, EMI has become a wholly-owned subsidiary of Sony. This acquisition allows Sony to build upon its music publishing library by providing the Company with full ownership of the EMI Music Publishing catalog which was being administered by Sony’s wholly-owned music publishing subsidiary, Sony/ATV Music Publishing. Sony’s consolidated income statements for the fiscal year ended March 31, 2019 include revenue and operating income of 28,871 million yen (260 million U.S. dollars) and 6,432 million yen (58 million U.S. dollars), respectively, attributable to EMI since the date of acquisition. Sony’s consolidated income statements for the three months ended March 31, 2019 include revenue and operating income of 18,420 million yen (167 million U.S. dollars) and 4,522 million yen (41 million U.S. dollars), respectively, attributable to EMI.

Prior to the acquisition, Sony’s interest in EMI was accounted for under the equity method of accounting. As a result of Sony obtaining a controlling interest in EMI, Sony consolidated EMI using the acquisition method of accounting and recorded the fair value of the identifiable assets, liabilities assumed and residual goodwill of EMI. Sony remeasured the approximately 40% equity interest in EMI that Sony already owned prior to the acquisition at a fair value of 141,141 million yen (1,245 million U.S. dollars) which resulted in the recognition of a

non-cash

gain of 116,939 million yen (1,032 million U.S. dollars) recorded in other operating income, net for the three months ended December 31, 2018. Sony did not record any tax expense or deferred tax liability corresponding to this gain. Sony also assumed EMI’s existing interest-bearing debt of 148,621 million yen (1,311 million U.S. dollars) as a result of this acquisition, of which 108,942 million yen (961 million U.S. dollars) was repaid immediately from Sony’s existing cash.

Intangibles mainly consists of music publishing catalogs with weighted average amortization periods of 43 years. Goodwill represents unidentifiable intangible assets, such as future growth from new revenue streams and synergies with existing Sony assets and businesses, and is calculated as the excess of the purchase price over the estimated fair value of the tangible and intangible assets acquired and is not deductible for tax purposes. The goodwill recorded in connection with this acquisition is included in the Music segment.

27.	Collaborative arrangements

 

 

Sony’s collaborative arrangements primarily relate to arrangements entered into, through subsidiaries in the Pictures segment, with one or more active participants to jointly finance, produce and/or distribute motion pictures or television programming under which both the subsidiaries and the other active participants share in the risks and rewards of ownership. These arrangements are referred to as

co-production

and distribution arrangements.

Sony typically records an asset for only the portion of the motion pictures or television programming it owns and finances. Sony and the other participants typically distribute the product in different media or markets. Revenues earned and expenses incurred for the media or markets in which Sony distributes the product are typically recorded on a gross basis. Sony typically does not record revenues earned and expenses incurred when the other participants distribute the product. Sony and the other participants typically share in the profits from the distribution of the product in all media or markets. For motion pictures, if Sony is a net receiver of (1) Sony’s share of the profits from the media or markets distributed by the other participants less (2) the other participants’ share of the profits from the media or markets distributed by Sony then the net amount is recorded as net sales. If Sony is a net payer then the net amount is recorded in cost of sales. For television programming, Sony records its share of the profits from the media or markets distributed by the other participants as sales, and the other participants’ share of the profits from the media or markets distributed by Sony as cost of sales.

For the fiscal years ended March 31, 2018, 2019 and 2020, 49,547 million yen, 42,343 million yen and 33,921 million yen, respectively, were recorded as net sales for amounts due from the other participants and 24,280 million yen, 22,702 million yen and 21,052 million yen, respectively, were recorded as cost of sales for amounts owed to the other participants in these collaborative arrangements.

28.	Commitments, contingent liabilities and other

 

 

 

(1)	Loan commitments

 

 

 

Subsidiaries in the Financial Services segment have entered into loan agreements with their customers in accordance with the condition of the contracts. As of March 31, 2020, the total unused portion of the lines of credit extended under these contracts was 34,306 million yen. Based upon the information currently available, it is not possible to estimate the aggregate amounts of future

year-by-year

payments for these loan commitments.

(2)	Purchase commitments and other

 

 

 

Purchase commitments and other outstanding as of March 31, 2020 amounted to 684,911 million yen. The major components of these commitments are as follows:

Certain subsidiaries in the Pictures segment have entered into agreements with creative talent for the development and production of motion pictures and television programming as well as agreements with third parties to acquire completed motion pictures, or certain rights therein, and to acquire the rights to broadcast certain live action sporting events. These agreements cover various periods mainly within three years. As of March 31, 2020, these subsidiaries were committed to make payments under such contracts of 126,917 million yen.

Certain subsidiaries in the Music segment have entered into contracts with recording artists, songwriters and companies for the future production, distribution and/or licensing of music product.

(3)	Litigation

 

 

 

Beginning in 2009, the U.S. Department of Justice (“DOJ”), the European Commission and certain other governmental agencies outside the United States have conducted investigations relating to competition in the optical disk drives market. Sony Corporation and/or certain of its subsidiaries have been subject to these investigations. Sony

Corporation

understands that these investigations have ended. However, proceedings initiated by the European Commission as a result of its investigation continue. In October 2015, the European Commission adopted a decision in which it fined Sony Corporation and certain of its subsidiaries 31 million euros; however, Sony

Corporation

filed an appeal against the decision with the European Union’s General Court. In July 2019, the General Court upheld the European Commission’s decision. Sony

 Corporation

reviewed the judgment carefully and filed an appeal with the Court of Justice of the European Union in September 2019. A number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceedings will not have a material impact on Sony’s results of operations and financial position.

Since 2011, in relation to the secondary batteries business that was operated by Sony

Corporation

and certain of its subsidiaries, a number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceeding will not have a material impact on Sony’s results of operations and financial position.

In addition, Sony Corporation and certain of its subsidiaries are defendants or otherwise involved in other pending legal and regulatory proceedings. However, based upon the information currently available, Sony believes that the outcome from such legal and regulatory proceedings would not have a material impact on Sony’s results of operations and financial position.

(4)	Guarantees

 

 

 

Sony has issued guarantees that contingently require payments to guaranteed parties if certain specified events or conditions occur. The maximum potential amount of future payments under these guarantees as of March 31, 2020 amounted to 2,214 million yen.

In connection with this realignment, the sales and operating revenue and operating income (loss) of each segment for the comparative periods have been reclassified to conform to the current presentation. In addition, the former Semiconductors segment has been renamed the I&SS segment effective from the first quarter of the fiscal year ended March 31, 20

20.

The G&NS segment includes network services businesses, the manufacture and sales of home gaming products and production and sales of software. The Music segment includes the Recorded Music, Music Publishing and Visual Media and Platform businesses. The Pictures segment includes the Motion Pictures, Television Productions and Media Networks businesses. The

EP&S segment includes the Televisions business, the Audio and Video business, the Still and Video Cameras business, the smartphone business and Internet-related service business.

Exhibit 2.2

Description of Rights of each Class of Securities

Registered under Section 12 of the Securities Exchange Act of 1934 (the “Exchange Act”)

Sony Corporation is a joint-stock corporation (Kabushiki Kaisha) incorporated in Japan under the Companies Act (Kaishaho) of Japan. It is registered in the Commercial Register (Shogyo Tokibo) maintained by the Minato Branch Office of the Tokyo Legal Affairs Bureau.

American Depositary Shares (“ADSs”), each representing one (1) share of common stock (“Share”) of Sony Corporation, are listed and traded on the New York stock Exchange, or the NYSE, under the symbol “SNE,” and in connection with this listing (but not for trading), the Shares are registered under Section 12(b) of the Exchange Act. This exhibit contains a description of the rights of (i) the holders of Shares and (ii) the holders of ADSs. Shares underlying the ADSs are held by Citibank, N.A., as depositary, and holders of ADSs are not treated as holders of Shares.

I. Description of Common Shares

Unless indicated otherwise, set forth below is information concerning the shares of Sony Corporation’s capital stock, including brief summaries of the relevant provisions of Sony Corporation’s Articles of Incorporation and Share Handling Regulations, currently in effect, and of the Companies Act and related regulations. Because it is a summary, this discussion should be read together with Sony Corporation’s Articles of Incorporation and Share Handling Regulations. Capitalized terms used but not defined herein have the meanings given to them in Sony Corporation’s annual report on Form 20-F for the fiscal year ended March 31, 2020.

General

On January 5, 2009, a central book-entry transfer system for shares of Japanese listed companies was established pursuant to the Act Concerning Book-entry Transfer of Corporate Bonds, Shares, etc. (including regulations promulgated thereunder, “Book-entry Transfer Act”), and this system is applied to the shares of Common Stock of Sony Corporation. Under this system, shares of all Japanese companies listed on any Japanese stock exchange are dematerialized, and shareholders must have accounts at account management institutions to hold their shares unless such shareholder has an account at Japan Securities Depository Center, Inc. (“JASDEC”). “Account management institutions” are financial instruments traders (i.e., securities companies), banks, trust companies and certain other financial institutions that meet the requirements prescribed by the Book-entry Transfer Act. Transfer of the shares of Common Stock of Sony Corporation is effected exclusively through entry in the records maintained by JASDEC and the account management institutions, and title to the shares passes to the transferee at the time when the transfer of the shares is recorded at the transferee’s account at an account management institution. The holder of an account at an account management institution is presumed to be the legal holder of the shares recorded in such account.

Under the Companies Act and the Book-entry Transfer Act, in order to assert shareholders’ rights against Sony Corporation, a shareholder of shares must have its name and address registered in Sony Corporation’s register of shareholders. Under the central book-entry transfer system operated by JASDEC, shareholders shall notify the relevant account management institutions of certain information prescribed under the Book-entry Transfer Act or Sony Corporation’s Share Handling Regulations, including their names and addresses, and the registration on Sony Corporation’s register of shareholders is updated upon receipt by Sony Corporation of necessary information from JASDEC (as described in “Record date”). On the other hand, in order to assert, against Sony Corporation, shareholders’ rights to which shareholders are entitled, regardless of whether such shareholder held shares on the requisite record date, such as minority shareholders’ rights, including the right to propose a matter to be considered at a General Meeting of Shareholders, except for shareholders’ rights to request that Sony Corporation purchase or sell shares constituting less than a full unit (as described in “Unit share system”), JASDEC shall, upon the shareholder’s request, issue a notice of certain information, including the name and address of such shareholder, to Sony Corporation.

Thereafter, such shareholder is required to present Sony Corporation a receipt of the notice request in accordance with the Sony Corporation’s Share Handling Regulations. Under the Book-entry Transfer Act, the shareholder shall exercise such shareholders’ right within four weeks after the notice above has been given to Sony Corporation.

Mitsubishi UFJ Trust and Banking Corporation is the transfer agent for Sony Corporation’s capital stock. As such, it keeps Sony Corporation’s register of shareholders in its office at 4-5, Marunouchi 1-chome, Chiyoda-ku, Tokyo.

---

Non-resident shareholders are required to appoint a standing proxy in Japan or file notice of a mailing address in Japan. Notices from Sony Corporation to non-resident shareholders are delivered to such standing proxies or mailing address. Japanese securities companies and commercial banks customarily act as standing proxies and provide related services for standard fees. The recorded holder of deposited shares underlying the ADSs is the depositary for the ADSs. Accordingly, holders of ADSs will not be able to directly assert shareholders’ rights against Sony Corporation.

Authorized capital

Under the Articles of Incorporation of Sony Corporation, Sony Corporation may only issue shares of Common Stock. Sony Corporation’s Articles of Incorporation provide that the total number of shares authorized to be issued by Sony Corporation is 3.6 billion shares.

All shares of capital stock of Sony Corporation have no par value. All issued shares are fully-paid and non-assessable.

Distribution of Surplus

Distribution of Surplus — General

Under the Companies Act, distributions of cash or other assets by joint stock corporations to their shareholders, so called “dividends,” are referred to as “distributions of Surplus” (“Surplus” is defined in “— Restriction on distribution of Surplus”). Sony Corporation may make distributions of Surplus to shareholders any number of times per business year, subject to certain limitations described in “— Restriction on distribution of Surplus.” Distributions of Surplus are required in principle to be authorized by a resolution of a General Meeting of Shareholders, but Sony Corporation may authorize distributions of Surplus by a resolution of the Board of Directors as long as its non-consolidated annual financial statements and certain documents for the last business year present fairly its assets and profit or loss, as required by ordinances of the Ministry of Justice.

Distributions of Surplus may be made in cash or in kind in proportion to the number of shares of Common Stock held by each shareholder. A resolution of the Board of Directors or a General Meeting of Shareholders authorizing a distribution of Surplus must specify the kind and aggregate book value of the assets to be distributed, the manner of allocation of such assets to shareholders, and the effective date of the distribution. If a distribution of Surplus is to be made in kind, Sony Corporation may, pursuant to a resolution of the Board of Directors or (as the case may be) a General Meeting of Shareholders, grant a right to the shareholders to require Sony Corporation to make such distribution in cash instead of in kind. If no such right is granted to shareholders, the relevant distribution of Surplus must be approved by a special resolution of a General Meeting of Shareholders (refer to “Voting rights” with respect to a “special resolution”).

Under the Articles of Incorporation of Sony Corporation, year-end dividends and interim dividends may be distributed in cash to shareholders appearing in Sony Corporation’s register of shareholders as of March 31 and September 30 each year, respectively, in proportion to the number of shares of Common Stock held by each shareholder following approval by the Board of Directors or (as the case may be) the General Meeting of Shareholders. Sony Corporation is not obliged to pay any dividends in cash unclaimed for a period of five years after the date on which they first became payable.

In Japan, the ex-dividend date and the record date for dividends precede the date of determination of the amount of the dividends to be paid. The price of the shares of Common Stock generally goes ex-dividend on the business day immediately prior to the record date (or if the record date is not a business day, the second business day prior thereto).

Distribution of Surplus — Restriction on distribution of Surplus

In making a distribution of Surplus, Sony Corporation must, until the sum of its additional paid-in capital and legal reserve reaches one quarter of its stated capital, set aside in its additional paid-in capital and/or legal reserve an amount equal to one-tenth of the amount of Surplus so distributed.

---

The amount of Surplus at any given time must be calculated in accordance with the following formula:

A + B + C + D - (E + F + G)

In the above formula:

 

“A” =		the total amount of other capital surplus and other retained earnings, each such amount being that appearing on the non-consolidated balance sheet as of the end of the last business year
“B” =		(if Sony Corporation has disposed of its treasury stock after the end of the last business year) the amount of the consideration for such treasury stock received by Sony Corporation less the book value thereof
“C” =		(if Sony Corporation has reduced its stated capital after the end of the last business year) the amount of such reduction less the portion thereof that has been transferred to additional paid-in capital or legal reserve (if any)
“D” =		(if Sony Corporation has reduced its additional paid-in capital or legal reserve after the end of the last business year) the amount of such reduction less the portion thereof that has been transferred to stated capital (if any)
“E” =		(if Sony Corporation has cancelled its treasury stock after the end of the last business year) the book value of such treasury stock
“F” =		(if Sony Corporation has distributed Surplus to its shareholders after the end of the last business year) the total book value of the Surplus so distributed
“G” =		certain other amounts set forth in ordinances of the Ministry of Justice, including (if Sony Corporation has reduced Surplus and increased its stated capital, additional paid-in capital or legal reserve after the end of the last business year) the amount of such reduction and (if Sony Corporation has distributed Surplus to the shareholders after the end of the last business year) the amount set aside in additional paid-in capital or legal reserve (if any) as required by ordinances of the Ministry of Justice.

The aggregate book value of Surplus distributed by Sony Corporation may not exceed a prescribed distributable amount (the “Distributable Amount”), as calculated on the effective date of such distribution. The Distributable Amount at any given time shall be equal to the amount of Surplus less the aggregate of the following:

 

(a)

the book value of its treasury stock;

 

(b)

the amount of consideration for any of treasury stock disposed of by Sony Corporation after the end of the last business year; and

 

(c)

certain other amounts set forth in ordinances of the Ministry of Justice, including (if the sum of one-half of goodwill and the deferred assets exceeds the total of stated capital, additional paid-in capital and legal reserve, each such amount being that appearing on the non-consolidated balance sheet as of the end of the last business year) all or certain part of such exceeding amount as calculated in accordance with ordinances of the Ministry of Justice.

As Sony Corporation has become a company with respect to which consolidated balance sheets should also be considered in the calculation of the Distributable Amount (renketsu haito kisei tekiyo kaisha), Sony Corporation must further deduct from the amount of Surplus the excess amount, if any, of (x) the total amount of stockholders’ equity appearing on the non-consolidated balance sheet as of the end of the last business year and certain other amounts set forth by an ordinance of the Ministry of Justice over (y) the total amount of stockholders’ equity and certain other amounts set forth by an ordinance of the Ministry of Justice appearing on the consolidated balance sheet as of the end of the last business year.

If Sony Corporation has prepared interim financial statements as described below, and if such interim financial statements have been approved by the Board of Directors or (if so required by the Companies Act) by a General Meeting of Shareholders, then the Distributable Amount must be adjusted to take into account the amount of profit or loss, and the amount of consideration for any of the treasury stock disposed of by Sony Corporation, during the period in respect of which such interim financial statements have been prepared. Sony Corporation may prepare non-consolidated interim financial statements consisting of a balance sheet as of any date subsequent to the end of the last business year and an income statement for the period from the first day of the current business year to the date of such balance sheet. Interim financial statements so prepared by Sony Corporation must be audited by the Audit Committee and the independent auditor, as required by the Companies Act and in accordance with the details prescribed by ordinances of the Ministry of Justice.

---

Capital and reserves

Sony Corporation may generally reduce its additional paid-in capital or legal reserve by resolution of a General Meeting of Shareholders and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as stated capital. On the other hand, Sony Corporation may generally reduce its stated capital by a special shareholders’ resolution (as defined in “Voting rights”) and, if so decided by the same resolution, may account for the whole or any part of the amount of such reduction as additional paid-in capital. In addition, Sony Corporation may reduce its Surplus and increase either (i) stated capital or (ii) additional paid-in capital and/or legal reserve by the same amount, in either case by resolution of a General Meeting of Shareholders.

Stock splits

Sony Corporation may at any time split shares in issue into a greater number of shares at the determination of the CEO, and may amend its Articles of Incorporation to increase the number of the authorized shares to be issued to allow such stock split pursuant to a resolution of the Board of Directors or a determination by a Corporate Executive Officer to whom the authority to make such determination has been delegated by a resolution of the Board of Directors, rather than relying on a special shareholders’ resolution, which is otherwise required for amending the Articles of Incorporation.

When a stock split is to be made, Sony Corporation must give public notice of the stock split, specifying the record date thereof, at least two weeks prior to such record date. Under the central book-entry transfer system operated by JASDEC, Sony Corporation must also give notice to JASDEC regarding a stock split at least two weeks prior to the relevant effective date of the stock split. On the effective date of the stock split, the numbers of shares recorded in all accounts held by Sony Corporation’s shareholders at account managing institutions or JASDEC will be increased in accordance with the applicable ratio.

Consolidation of shares

Sony Corporation may at any time consolidate issued shares into a smaller number of shares by a special shareholders’ resolution. When a consolidation of shares is to be made, Sony Corporation must give public notice or notice to each shareholder at least two weeks prior to the effective date of the consolidation of shares. Under the central book-entry transfer system operated by JASDEC, Sony Corporation must also give notice to JASDEC regarding a consolidation of shares at least two weeks prior to the effective date of the consolidation of shares. On the effective date of the consolidation of shares, the numbers of shares recorded in all accounts held by Sony Corporation’s shareholders at account managing institutions or JASDEC will be decreased in accordance with the applicable ratio. Sony Corporation must disclose the reason for the consolidation of shares at a General Meeting of Shareholders.

General Meeting of Shareholders

The Ordinary General Meeting of Shareholders of Sony Corporation for each business year is normally held in June of each year in Tokyo, Japan. In addition, Sony Corporation may hold an Extraordinary General Meeting of Shareholders whenever necessary by giving notice thereof at least two weeks prior to the date set for the meeting.

Notice of a shareholders’ meeting setting forth the place, time and purpose thereof must be mailed to each shareholder having voting rights (or, in the case of a non-resident shareholder, to such shareholder’s resident proxy or mailing address in Japan) at least two weeks prior to the date set for the meeting. Under the Companies Act, such notice may be given to shareholders by electronic means, subject to obtaining consent by the relevant shareholders. The record date for an Ordinary General Meeting of Shareholders is March 31 of each year.

Any shareholder or group of shareholders holding at least 3% of the total number of voting rights for a period of six months or more may require the convocation of a General Meeting of Shareholders for a particular purpose. Unless such a shareholders’ meeting is convened promptly or a convocation notice of a meeting which is to be held not later than eight weeks from the day of such demand is dispatched, the requiring shareholder may, upon obtaining a court approval, convene such a shareholders’ meeting.

Any shareholder or group of shareholders holding at least 300 voting rights or 1% of the total number of voting rights for a period of six months or more may propose a matter to be considered at a General Meeting of Shareholders by submitting a written request to Sony Corporation at least eight weeks prior to the date set for such meeting.

If the Articles of Incorporation so provide, any of the minimum voting rights or percentages, time periods and number of voting rights necessary for exercising the minority shareholder rights described above may be decreased or shortened. Sony Corporation’s Articles of Incorporation currently do not include any such provisions.

---

Voting rights

So long as Sony Corporation maintains the unit share system, a holder of shares constituting one or more units is entitled to one vote for each such unit of stock (refer to “Unit share system” below; currently 100 shares constitute one unit), except that no voting rights with respect to shares of capital stock of Sony Corporation are afforded to Sony Corporation or any corporate or certain other entities more than one-quarter of the total voting rights of which are directly or indirectly held by Sony Corporation. If Sony Corporation eliminates from its Articles of Incorporation the provisions relating to units of stock, holders of capital stock will have one vote for each share they hold. Except as otherwise provided by law or by the Articles of Incorporation of Sony Corporation, a resolution can be adopted at a General Meeting of Shareholders by a majority of the number of voting rights of all the shareholders represented at the meeting. The Companies Act and Sony Corporation’s Articles of Incorporation provide, however, that the quorum for the election of Directors shall be one-third of the total number of voting rights of all the shareholders. Sony Corporation’s shareholders are not entitled to cumulative voting in the election of Directors. Shareholders may cast their votes in writing and may also exercise their voting rights through proxies, provided that the proxies are also shareholders holding voting rights. Shareholders may also exercise their voting rights by electronic means pursuant to the method designated by Sony Corporation.

The Companies Act and the Articles of Incorporation of Sony Corporation provide that in order to amend the Articles of Incorporation and in certain other instances, including:

 

(1)

acquisition of its own shares from a specific party other than its subsidiaries;

 

(2)

consolidation of shares;

 

(3)

any offering of new shares or existing shares held by Sony Corporation as treasury stock at a “specially favorable” price (or any offering of stock acquisition rights to acquire shares of capital stock, or bonds with stock acquisition rights on “specially favorable” conditions) to any persons other than shareholders;

 

(4)

the exemption of liability of a Director, Corporate Executive Officer or independent auditor with certain exceptions;

 

(5)

a reduction of stated capital with certain exceptions;

 

(6)

a distribution of in-kind dividends which meets certain requirements;

 

(7)

dissolution, merger, consolidation, or corporate split with certain exceptions;

 

(8)

the transfer of the whole or a material part of the business;

 

(9)

the transfer of the whole or a part of the shares or equity interests in a subsidiary which meets certain requirements;

 

(10)

the taking over of the whole of the business of any other corporation with certain exceptions; or

 

(11)

share exchange or share transfer for the purpose of establishing 100% parent-subsidiary relationships with certain exceptions,

the quorum shall be one-third of the total number of voting rights of all the shareholders, and the approval by at least two-thirds of the number of voting rights of all the shareholders represented at the meeting is required (the “special shareholders’ resolutions”).

Issue of additional shares and pre-emptive rights

Holders of Sony Corporation’s shares of capital stock have no pre-emptive rights under its Articles of Incorporation. Authorized but unissued shares may be issued, or existing shares held by Sony Corporation as treasury stock may be transferred, at such times and upon such terms as the Board of Directors or the CEO determines, subject to the limitations as to the offering of new shares or transfer of existing shares held by Sony Corporation as treasury stock at a “specially favorable” price mentioned under “Voting rights” above.

In the case of an issuance of shares (including a transfer of existing shares held by Sony Corporation as treasury stock) or stock acquisition rights whereby any subscriber will hold more than 50% of the voting rights of all shareholders, generally Sony Corporation shall give public notice at least two weeks prior to the payment date for such issuance, and if shareholders who hold one-tenth or more of the voting rights of all shareholders dissent from the issuance of shares or stock acquisition rights, the approval by a resolution of a General Meeting of

---

Shareholders is generally required before the payment date pursuant to the Companies Act. In addition, in the case of an issuance of shares (including a transfer of existing shares held by Sony Corporation as treasury stock) or stock acquisition rights by way of an allotment to a third party which would dilute the outstanding voting shares by 25% or more or change the controlling shareholder, in addition to a resolution of the Board of Directors, the approval of the shareholders or an affirmative vote from a person independent of the management is generally required pursuant to the rules of the TSE. The Board of Directors or the CEO may, however, determine that shareholders shall be given subscription rights regarding a particular issue of new shares, in which case such rights must be given on uniform terms to all shareholders as of a record date of which not less than two weeks’ prior public notice is given. Each of the shareholders to whom such rights are given must also be given notice of the expiry thereof at least two weeks prior to the date on which such rights expire.

Subject to certain conditions, Sony Corporation may issue stock acquisition rights by a resolution of the Board of Directors or a determination by the CEO. Holders of stock acquisition rights may exercise their rights to acquire a certain number of shares within the exercise period as prescribed in the terms of their stock acquisition rights. Upon exercise of stock acquisition rights, Sony Corporation will be obliged to issue the relevant number of new shares or alternatively to transfer the necessary number of shares of treasury stock held by it.

In cases where a particular issue of new shares or stock acquisition rights (i) violates laws and regulations or Sony Corporation’s Articles of Incorporation, or (ii) will be performed in a materially unfair manner, and shareholders may suffer disadvantages therefrom, such shareholders may file an injunction to enjoin such issue with a court.

Liquidation rights

In the event of a liquidation of Sony Corporation, the assets remaining after payment of all debts, liquidation expenses and taxes will be distributed among the holders of shares of Common Stock in proportion to the respective numbers of shares of Common Stock held.

March 31 is the record date for Sony Corporation’s year-end dividends, if declared. So long as Sony Corporation maintains the unit share system, shareholders who are registered as the holders of one or more unit of stock in Sony Corporation’s register of shareholders at the end of each March 31 are also entitled to exercise shareholders’ rights at the Ordinary General Meeting of Shareholders with respect to the business year ending on such March 31. September 30 is the record date for interim dividends, if declared. In addition, Sony Corporation may set a record date for determining the shareholders entitled to other rights and for other purposes by giving at least two weeks’ prior public notice.

JASDEC is required to promptly give Sony Corporation notice of the names and addresses of Sony Corporation’s shareholders, the numbers of shares of Common Stock held by them and other relevant information as of such respective record dates.

The price of shares generally goes ex-dividends or ex-rights on Japanese stock exchanges on the business day immediately prior to a record date (or if the record date is not a business day, the second business day prior thereto), for the purpose of dividends or rights offerings.

Acquisition by Sony Corporation of its capital stock

Under the Companies Act and the Articles of Incorporation of Sony Corporation, Sony Corporation may acquire shares of Common Stock (i) from a specific shareholder other than any of its subsidiaries (pursuant to the special shareholders’ resolution), (ii) from any of its subsidiaries (pursuant to a determination by the CEO as delegated by the Board of Directors), or (iii) by way of purchase on any Japanese stock exchange on which Sony Corporation’s shares of Common Stock are listed or by way of tender offer (pursuant to a resolution of the Board of Directors, as long as its non-consolidated annual financial statements and certain documents for the last business year present fairly its assets and profit or loss, as required by ordinances of the Ministry of Justice).

In the case of (i) above, any other shareholder may make a request to Sony Corporation that such other shareholder be included as a seller in the proposed purchase, provided that no such right will be available if the purchase price or any other consideration to be received by the relevant specific shareholder will not exceed the last trading price of the shares on the relevant stock exchange on the day immediately preceding the date on which the resolution mentioned in (i) above was adopted (or, if there is no trading in the shares on the stock exchange or if the stock exchange is not open on such day, the price at which the shares are first traded on such stock exchange thereafter).

---

The total amount of the purchase price of shares of Common Stock may not exceed the Distributable Amount, as described in “Distribution of Surplus — Distribution of Surplus — Restriction on distribution of Surplus.”

Shares acquired by Sony Corporation may be held for any period or may be retired at the determination of the CEO. Sony Corporation may also transfer (by public or private sale or otherwise) to any person the treasury stock held by it, subject to a determination by the CEO, and subject also to other requirements similar to those applicable to the issuance of new shares, as described in “Issue of additional shares and pre-emptive rights” above. Sony Corporation may also utilize its treasury stock for the purpose of transfer to any person upon exercise of stock acquisition rights or for the purpose of acquiring another company by way of merger, share exchange or corporate split through exchange of treasury stock for shares or assets of the acquired company.

Unit share system

The Articles of Incorporation of Sony Corporation provide that 100 shares constitute one “unit” of shares of stock. The Board of Directors or the Corporate Executive Officer to whom the authority to make such a determination has been delegated by a resolution of the Board of Directors is permitted to amend the Articles of Incorporation to reduce the number of shares that constitute a unit or to abolish the unit share system entirely. Under the Companies Act, the number of shares constituting one unit cannot exceed 1,000 shares nor 0.5% of the total number of issued shares.

Under the unit share system, shareholders have one voting right for each unit of stock that they hold. Any number of shares less than one full unit have neither voting rights nor rights related to voting rights. Holders of shares constituting less than one unit will have no other shareholder rights if Sony Corporation’s Articles of Incorporation so provide, except that such holders may not be deprived of certain rights specified in the Companies Act or an ordinance of the Ministry of Justice, including the right to receive distribution of Surplus.

A holder of shares constituting less than one full unit may require Sony Corporation to purchase such shares at their market value in accordance with the provisions of the Share Handling Regulations of Sony Corporation. In addition, the Articles of Incorporation of Sony Corporation provide that a holder of shares constituting less than one full unit may request Sony Corporation to sell to such holder such amount of shares which will, when added together with the shares constituting less than one full unit, constitute one full unit of stock. Such request by a holder and the sale by Sony Corporation must be made in accordance with the provisions of the Share Handling Regulations of Sony Corporation. As prescribed in the Share Handling Regulations, such requests shall be made through an account management institution and JASDEC pursuant to the rules set by JASDEC, without going through the notification procedure required for the exercise of the shareholders’ rights to which shareholders are entitled, regardless of whether such shareholder held shares on the requisite record date, as described in “General.” Shares constituting less than a full unit are transferable, under the central book-entry transfer system described in “General.” Under the rules of the Japanese stock exchanges, however, shares constituting less than a full unit do not comprise a trading unit, except in limited circumstances, and accordingly may not be sold on the Japanese stock exchanges.

Sale by Sony Corporation of shares held by shareholders whose location is unknown

Sony Corporation is not required to send a notice to a shareholder if a notice to such shareholder fails to arrive at the registered address of the shareholder in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation continuously for five years or more.

In addition, Sony Corporation may sell or otherwise dispose of shares of capital stock for which the location of the shareholder is unknown. Generally, if (i) notices to a shareholder fail to arrive continuously for five years or more at the shareholder’s registered address in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation, and (ii) the shareholder fails to receive distributions of Surplus on the shares continuously for five years or more at the address registered in Sony Corporation’s register of shareholders or at the address otherwise notified to Sony Corporation, Sony Corporation may sell or otherwise dispose of such shareholder’s shares at the then market price of the shares by a determination of a Corporate Executive Officer and after giving at least three months’ prior public and individual notice, and hold or deposit the proceeds of such sale or disposal of shares for such shareholder.

Reporting of substantial shareholdings

The Financial Instruments and Exchange Act of Japan and its related regulations require any person, regardless of residence, who has become, beneficially and solely or jointly, a holder of more than 5% of the total

---

issued shares of capital stock of a company listed on any Japanese stock exchange or whose shares are traded on the over-the-counter market in Japan to file with the Director General of the competent Local Finance Bureau of the Ministry of Finance within five business days a report concerning such shareholdings. A similar report must also be filed in respect of any subsequent change of 1% or more in any such holding, or any change in material matters set out in reports previously filed, with certain exceptions. For this purpose, shares issuable to such persons upon conversion of convertible securities or exercise of share subscription warrants or stock acquisition rights are taken into account in determining both the number of shares held by such holders and the issuer’s total issued share capital. Any such report shall be filed with the Director General of the relevant Local Finance Bureau of the Ministry of Finance through the Electronic Disclosure for Investors’ Network (EDINET) system.

Ownership restrictions

Except for the general limitation under Japanese anti-trust and anti-monopoly regulations against holding of shares of capital stock of a Japanese corporation which leads or may lead to a restraint of trade or monopoly, except for the limitations under the Foreign Exchange Regulations as described in “Item 10D. Exchange Controls” of Sony Corporation’s annual report on Form 20-F for the fiscal year ended March 31, 2020, and except for general limitations under the Companies Act or Sony Corporation’s Articles of Incorporation on the rights of shareholders applicable regardless of residence or nationality, there is no limitation under Japanese laws and regulations applicable to Sony Corporation or under its Articles of Incorporation on the rights of non-residents or foreign shareholders to hold or exercise voting rights on the shares of capital stock of Sony Corporation.

There is no provision in Sony Corporation’s Articles of Incorporation or internal regulations that would have an effect of delaying, deferring or preventing a change in control of Sony Corporation and that would operate only with respect to a merger, acquisition or corporate restructuring involving Sony Corporation.

II. Description of American Depositary Shares

General

Citibank, N.A. serves as the Depositary for the American Depositary Shares. Citibank’s depositary offices are located at 388 Greenwich Street, New York, New York 10013. American Depositary Shares are frequently referred to as “ADSs” and represent ownership interests in securities that are on deposit with the Depositary. ADSs may be represented by certificates that are commonly known as “American Depositary Receipts” or “ADRs.” The Depositary typically appoints a custodian to safekeep the securities on deposit. In this case, the Custodian is The Bank of Tokyo-Mitsubishi UFJ, Ltd., having its principal office at Global Securities Services Division, 3-2, Nihombashi Hongokucho 1-Chome, Chuo-ku, Tokyo 103-0021 Japan.

Sony Corporation has appointed Citibank as Depositary pursuant to a Deposit Agreement. A copy of the Deposit Agreement is on file with the SEC under cover of a Registration Statement on Form F-6. Holders of ADSs may obtain a copy of the Deposit Agreement from the SEC’s Public Reference Room at 100 F Street, N.E., Washington, D.C. 20549 and from the SEC’s website (www.sec.gov). Please refer to Registration Number 333-198953 when retrieving such copy.

Sony Corporation is providing this summary description of the material terms of the ADSs and of ADS holders’ material rights as owners of ADSs. Please remember that summaries by their nature lack the precision of the information summarized and that the rights and obligations of ADS owners will be determined by reference to the terms of the Deposit Agreement and not by this summary. This summary should be read together with Sony Corporation’s Deposit Agreement in its entirety. Capitalized terms used but not defined herein have the meanings given to them in the Deposit Agreement. The portions of this summary description that are italicized describe matters that may be relevant to the ownership of ADSs but that may not be contained in the Deposit Agreement.

Each ADS represents the right to receive, and to exercise the beneficial ownership interests in, one Share that is on deposit with the Depositary and/or the Custodian. An ADS also represents the right to receive, and to exercise the beneficial interests in, any other property received by the Depositary or the Custodian on behalf of the owner of the ADS but that has not been distributed to an ADS owner because of legal restrictions or practical considerations. Sony Corporation and the Depositary may agree to change the ADS-to-Shares ratio by amending the Deposit Agreement. This amendment may give rise to, or change, the Depositary fees payable by ADS owners. The Custodian, the Depositary and their respective nominees will hold all deposited property for the benefit of the holders and beneficial owners of ADSs. The deposited property does not constitute the proprietary assets of the Depositary, the Custodian or their nominees. Beneficial ownership in the deposited property will under the terms of the Deposit Agreement be vested in the beneficial owners of the ADSs. The Depositary, the Custodian and their respective nominees will be the record holders of the deposited property represented by the

---

ADSs for the benefit of the holders and beneficial owners of the corresponding ADSs. A beneficial owner of ADSs may or may not be the holder of ADSs. Beneficial owners of ADSs will be able to receive, and to exercise beneficial ownership interests in, the deposited property only through the registered holders of the ADSs, by the registered holders of the ADSs (on behalf of the applicable ADS owners) only through the Depositary, and by the Depositary (on behalf of the owners of the corresponding ADSs) directly, or indirectly, through the Custodian or their respective nominees, in each case upon the terms of the Deposit Agreement.

An owner of ADSs becomes a party to the Deposit Agreement and therefore will be bound to its terms and to the terms of any ADR that represents the ADSs. The Deposit Agreement and the ADR specify Sony Corporation’s rights and obligations as well as ADS holders’ rights and obligations as owners of ADSs and those of the Depositary. ADS holders appoint the Depositary to act on the holders’ behalf in certain circumstances. The Deposit Agreement and the ADRs are governed by New York law. However, Sony Corporation’s obligations to the holders of Shares will continue to be governed by the laws of Japan, which may be different from the laws in the United States.

In addition, applicable laws and regulations may require holders of ADSs to satisfy reporting requirements and obtain regulatory approvals in certain circumstances. Holders of ADSs are solely responsible for complying with such reporting requirements and obtaining such approvals. Neither the Depositary, the Custodian, Sony Corporation or any of their or Sony Corporation’s respective agents or affiliates shall be required to take any actions whatsoever on behalf of ADS holders to satisfy such reporting requirements or obtain such regulatory approvals under applicable laws and regulations.

Sony Corporation will not treat ADS holders as its shareholders and ADS holders will not have direct shareholder rights. The Depositary will hold on ADS holders’ behalves the shareholder rights attached to the Shares underlying their ADSs. ADS holders will be able to exercise the shareholder rights for the Shares represented by their ADSs through the Depositary only to the extent contemplated in the Deposit Agreement. To exercise any shareholder rights not contemplated in the Deposit Agreement, ADS owners need to arrange for the cancellation of their ADSs and become direct shareholders.

The manner in which a holder of ADSs owns the ADSs (e.g., in a brokerage account vs. as registered holder, or as holder of certificated vs. uncertificated ADSs) may affect the holder’s rights and obligations, and the manner in which, and extent to which, the Depositary’s services are made available to the holder. A holder of ADSs may hold ADSs either by means of an ADR registered in the holder’s name, through a brokerage or safekeeping account, or through an account established by the Depositary in the holder’s name reflecting the registration of uncertificated ADSs directly on the books of the Depositary (commonly referred to as the “direct registration system” or “DRS”). The direct registration system reflects the uncertificated (book-entry) registration of ownership of ADSs by the Depositary. Under the direct registration system, ownership of ADSs is evidenced by periodic statements issued by the Depositary to the holders of the ADSs. The direct registration system includes automated transfers between the Depositary and The Depository Trust Company (“DTC”), the central book-entry clearing and settlement system for equity securities in the United States. If a holder of ADSs decides to hold ADSs through the holder’s brokerage or safekeeping account, the holder must rely on the procedures of the holder’s broker or bank to assert the holder’s rights as an ADS owner. Banks and brokers typically hold securities such as ADSs through clearing and settlement systems such as DTC. The procedures of such clearing and settlement systems may limit an ADS holder’s ability to exercise the holder’s rights as an owner of ADSs. A holder of ADSs who has any questions concerning these limitations and procedures should consult with the holder’s broker or bank. All ADSs held through DTC will be registered in the name of a nominee of DTC.

The registration of the Shares in the name of the Depositary or the Custodian shall, to the maximum extent permitted by applicable law, vest in the Depositary or the Custodian the record ownership in the applicable Shares with the beneficial ownership rights and interests in such Shares being at all times vested with the beneficial owners of the ADSs representing the Shares. The Depositary or the Custodian shall at all times be entitled to exercise the beneficial ownership rights in all deposited property, in each case only on behalf of the holders and beneficial owners of the ADSs representing the deposited property.

Dividends and distributions

Holders of ADSs generally have the right to receive the distributions Sony Corporation makes on the securities deposited with the Custodian. An ADS holder’s receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders of ADSs will receive such distributions under the terms of the Deposit Agreement in proportion to the number of ADSs held as of the specified record date, after deduction of the applicable fees, taxes and expenses.

---

Distributions of cash

Whenever Sony Corporation makes a cash distribution for the securities on deposit with the Custodian, Sony Corporation will deposit the funds with the Custodian. Upon receipt of confirmation from the Custodian of the deposit of the requisite funds, the Depositary will, if at the time of receipt thereof any funds received in a currency other than U.S. dollars can, in the judgment of the Depositary, be converted on a practicable basis into U.S. dollars transferable to the United States, arrange for the funds so received to be converted into U.S. dollars and for the distribution of the U.S. dollars to the holders, subject to the laws and regulations of Japan.

The Depositary will apply the same method for distributing the proceeds of the sale of any property (such as undistributed rights) held by the Custodian in respect of securities on deposit.

The distribution of cash will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the Deposit Agreement. The Depositary will hold any cash amounts it is unable to distribute in a non-interest bearing account for the benefit of the applicable holders and beneficial owners of ADSs until the distribution can be effected or the funds that the Depositary holds must be escheated as unclaimed property in accordance with the laws of the relevant states of the United States.

Distributions of shares

Whenever Sony Corporation makes a free distribution of Shares for the securities on deposit with the Custodian, Sony Corporation will deposit the applicable number of Shares with the Custodian. Upon receipt of confirmation of such deposit, the Depositary will either distribute to holders new ADSs representing the Shares deposited or modify the ADS-to-Shares ratio, in which case each ADS held will represent rights and interests in the additional Shares so deposited. Only whole new ADSs will be distributed. Fractional entitlements will be sold and the proceeds of such sale will be distributed as in the case of a cash distribution.

The distribution of new ADSs or the modification of the ADS-to-Shares ratio upon a distribution of Shares will be made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the Deposit Agreement. In order to pay such taxes or governmental charges, the Depositary may sell all or a portion of the new Shares so distributed.

No such distribution of new ADSs will be made if it would violate a law (e.g., the U.S. securities laws) or if it is not operationally practicable. If the Depositary does not distribute new ADSs as described above, it may sell the Shares received upon the terms described in the Deposit Agreement and will distribute the proceeds of the sale as in the case of a distribution of cash.

Distributions of rights

Whenever Sony Corporation intends to distribute rights to subscribe for additional Shares, Sony Corporation will give prior notice to the Depositary and Sony Corporation will assist the Depositary in determining whether it is lawful and reasonably practicable to distribute rights to subscribe for additional ADSs to holders.

The Depositary will establish procedures to distribute rights to subscribe for additional ADSs to holders and to enable such holders to exercise such rights if it is lawful and reasonably practicable to make the rights available to ADS holders, and if Sony Corporation provides all of the documentation contemplated in the Deposit Agreement (such as opinions to address the lawfulness of the transaction). An ADS holder may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new ADSs upon the exercise of the holder’s rights. The Depositary is not obligated to establish procedures to facilitate the distribution and exercise by holders of rights to subscribe for new Shares other than in the form of ADSs.

The Depositary will not distribute the rights to holders of ADSs if:

 

•

Sony Corporation does not timely request that the rights be distributed to holders or Sony Corporation requests that the rights not be distributed to holders;

 

•

Sony Corporation fails to deliver reasonably satisfactory documents to the Depositary; or

 

•

It is not reasonably practicable to distribute the rights.

The Depositary will sell the rights that are not exercised or not distributed if such sale is lawful and reasonably practicable. The proceeds of such sale will be distributed to holders as in the case of a cash distribution. If the Depositary is unable to sell the rights, it will allow the rights to lapse.

---

Elective distributions

Whenever Sony Corporation intends to distribute a dividend payable at the election of shareholders either in cash or in additional shares, Sony Corporation will give prior notice thereof to the Depositary and will indicate whether Sony Corporation wishes the elective distribution to be made available to holders of ADSs. In such case, Sony Corporation will assist the Depositary in determining whether such distribution is lawful and reasonably practicable.

The Depositary will make the election available to holders of ADSs only if the Depositary has determined, upon consultation with Sony Corporation, that it is reasonably practicable and if Sony Corporation has provided all of the documentation contemplated in the Deposit Agreement. In such case, the Depositary will establish procedures to enable holders of ADSs to elect to receive either cash or additional ADSs, in each case as described in the Deposit Agreement.

If the election is not made available to holders of ADSs, holders will receive either cash or additional ADSs, depending on what a shareholder in Japan would receive upon failing to make an election, as more fully described in the Deposit Agreement.

Other distributions

Whenever Sony Corporation intends to distribute property other than cash, Shares or rights to subscribe for additional Shares, Sony Corporation will notify the Depositary in advance and will indicate whether Sony Corporation wishes such distribution to be made to ADS holders. If so, Sony Corporation will assist the Depositary in determining whether such distribution to ADS holders is lawful and reasonably practicable.

If it is reasonably practicable to distribute such property to holders of ADSs and if Sony Corporation provides to the Depositary all of the documentation contemplated in the Deposit Agreement, the Depositary will distribute the property to the holders in a manner it deems practicable.

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the Deposit Agreement. In order to pay such taxes and governmental charges, the Depositary may sell all or a portion of the property received.

The Depositary will not distribute the property to holders of ADSs and will sell the property if:

 

•

Sony Corporation does not request that the property be distributed to holders or if Sony Corporation requests that the property not be distributed to holders;

 

•

Sony Corporation does not deliver reasonably satisfactory documents to the Depositary; or

 

•

The Depositary determines, after consultation with Sony Corporation, that all or a portion of the distribution to holders is not reasonably practicable.

The proceeds of such a sale will be distributed to holders as in the case of a cash distribution.

Redemption

Whenever Sony Corporation decides to redeem any of the securities on deposit with the Custodian, Sony Corporation will notify the Depositary in advance. If the Depositary has determined, after consultation with Sony Corporation, that it is practicable and if Sony Corporation provides all of the documentation contemplated in the Deposit Agreement, the Depositary will provide notice of the redemption to the holders.

The Custodian will be instructed to surrender the Shares being redeemed against payment of the applicable redemption price. The Depositary will, as soon as reasonably practicable, convert into U.S. dollars upon the terms of the Deposit Agreement the redemption funds received in a currency other than U.S. dollars and will establish procedures to enable holders to receive the net proceeds from the redemption upon surrender of their ADSs to the Depositary. A holder of ADSs may have to pay fees, expenses, applicable taxes and other governmental charges upon the redemption of the holder’s ADSs. If less than all ADSs are being redeemed, the ADSs to be retired will be selected on a pro rata basis.

Changes affecting shares

The Shares held on deposit for holders’ ADSs may change from time to time. For example, there may be a change in nominal or par value, split-up, cancellation, consolidation or any other reclassification of such Shares or a recapitalization, reorganization, merger, consolidation or sale of assets of the Company.

---

If any such change were to occur, holders’ ADSs would, to the extent permitted by law and the Deposit Agreement, represent the right to receive the property received or exchanged in respect of the Shares held on deposit. The Depositary may in such circumstances deliver new ADSs to holders (and deliver ADRs evidencing such ADSs, as applicable), amend the Deposit Agreement, the form of ADR then outstanding and the applicable Registration Statement(s) on Form F-6, call for the exchange of holders’ existing ADRs for new ADRs and take any other actions reasonably requested by Sony Corporation or as the Depositary in consultation with Sony Corporation considers appropriate to reflect as to the ADSs the change affecting the Shares. If, in the reasonable judgment of the Depositary, upon consultation with Sony Corporation, the Depositary may not lawfully distribute such property to holders of ADSs, the Depositary may sell such property and distribute the net proceeds to holders as in the case of a cash distribution.

Issuance of ADSs upon deposit of shares

The Depositary may create ADSs on a holder’s behalf if the holder or the holder’s broker deposits Shares with the Custodian. The Depositary will deliver these ADSs to the person the holder indicates only after the holder pays any applicable issuance fees and any charges and taxes payable for the transfer of the Shares to the Custodian. A holder’s ability to deposit Shares and receive ADSs may be limited by U.S. and Japanese legal considerations applicable at the time of deposit.

The issuance of ADSs may be delayed until the Depositary or the Custodian receives confirmation that all required approvals have been given and that the Shares have been duly transferred to the Custodian. The Depositary will only issue ADSs in whole numbers.

When an ADS holder make a deposit of Shares, the holder will be responsible for transferring good and valid title to the Depositary. As such, the holder will be deemed to represent and warrant that:

 

•

The Shares are duly authorized, validly issued, fully paid, non-assessable and legally obtained;

 

•

All preemptive (and similar) rights, if any, with respect to such Shares have been validly waived or exercised;

 

•

The holder is duly authorized to deposit the Shares;

 

•

The Shares presented for deposit are free and clear of any lien, encumbrance, security interest, charge, mortgage or adverse claim, and are not, and the ADSs issuable upon such deposit will not be, “restricted securities” (as defined in the Deposit Agreement); and

 

•

The Shares presented for deposit have not been stripped of any rights or entitlements.

If any of the representations or warranties are incorrect in any way, Sony Corporation and the Depositary may, at the holder’s cost and expense, take any and all actions necessary to correct the consequences of the misrepresentations.

Transfer, combination and split up of ADRs

ADS holders are entitled to transfer, combine or split up their ADRs and the ADSs evidenced thereby. For transfers of ADRs, a holder will have to surrender the ADRs to be transferred to the Depositary and also must:

 

•

Ensure that the surrendered ADR is properly endorsed or otherwise in proper form for transfer;

 

•

Provide such proof of identity and genuineness of signatures as the Depositary deems appropriate;

 

•

Provide any transfer stamps required by the State of New York or the United States; and

 

•

Pay all applicable fees, charges, expenses, taxes and other government charges payable by ADR holders pursuant to the terms of the Deposit Agreement, upon the transfer of ADRs.

To have ADRs either combined or split up, a holder must surrender the ADRs in question to the Depositary with the holder’s request to have them combined or split up, and the holder must pay all applicable fees, charges and expenses payable by ADR holders, pursuant to the terms of the Deposit Agreement and of applicable law, upon a combination or split up of ADRs.

Withdrawal of shares upon cancellation of ADSs

ADS holders are entitled to present their ADSs to the Depositary for cancellation and then receive the corresponding number of underlying Shares at the Custodian’s offices. An ADS holder’s ability to withdraw the

---

Shares held in respect of the ADSs may be limited by U.S. and Japanese law considerations applicable at the time of withdrawal. In order to withdraw the Shares represented by a holder’s ADSs, the holder will be required to pay to the Depositary the fees for cancellation of ADSs and any charges and taxes payable upon the transfer of the Shares. The holder assumes the risk for delivery of all funds and securities upon withdrawal. Once canceled, the ADSs will not have any rights under the Deposit Agreement.

If ADSs are registered in the holder’s name, the Depositary may ask the holder to provide proof of identity and genuineness of any signature and such other documents as the Depositary may deem appropriate before it will cancel the holder’s ADSs. The withdrawal of the Shares represented by the holder’s ADSs may be delayed until the Depositary receives satisfactory evidence of compliance with all applicable laws and regulations. Holders of ADSs should keep in mind that the Depositary will only accept ADSs for cancellation that represent a whole number of securities on deposit.

Pursuant to the Companies Act of Japan and to Sony Corporation’s Articles of Incorporation, the release of the Shares may be limited to a unit of 100 Shares (or such other number of Shares as the Articles of Incorporation may from time to time designate as a “unit of shares”) or integral multiples thereof.

Holders of ADSs will have the right to withdraw the securities represented by the holders’ ADSs at any time except for:

 

•

Temporary delays that may arise because (i) the transfer books for the Shares or ADSs are closed, or (ii) Shares are immobilized on account of a shareholders’ meeting or a payment of dividends;

 

•

Obligations to pay fees, taxes and similar charges; or

 

•

Restrictions imposed because of laws or regulations applicable to ADSs or the withdrawal of securities on deposit.

The Deposit Agreement may not be modified to impair an ADS holder’s right to withdraw the securities represented by the holder’s ADSs except to comply with mandatory provisions of law.

Voting rights

Holders of ADSs generally have the right under the Deposit Agreement to instruct the Depositary to exercise the voting rights for the Shares represented by the holders’ ADSs. The voting rights of holders of Shares are described in “Description of Common Shares.”

At Sony Corporation’s request, and as soon as practicable after receipt thereof, the Depositary will distribute to ADS holders any notice of shareholders’ meeting received from Sony Corporation together with information explaining how to instruct the Depositary to exercise the voting rights of the securities represented by ADSs. In lieu of distributing such materials, the Depositary may, with the Company’s prior written consent and to the extent not prohibited by laws or regulations, or by the New York Stock Exchange, distribute to holders of ADSs instructions on how to retrieve such materials upon request.

If the Depositary timely receives voting instructions from a holder of ADSs, it will endeavor to vote the securities (in person or by proxy) represented by the holder’s ADSs in accordance with such voting instructions. The Depositary will not exercise any voting discretion over the securities on deposit.

If the Depositary does not receive timely voting instructions from an ADS holder, such holder will be deemed to have instructed the Depositary to give a discretionary proxy to a person designated by Sony Corporation to vote the securities on deposit, except with respect to any matter to be voted on as to which Sony Corporation informs the Depositary that (i) there is contest to the action to be taken at the meeting, (ii) the matter relates to authorizing a merger, consolidation or amalgamation (except an amalgamation with one or more of Sony Corporation’s 100%-owned Japanese subsidiaries), or (iii) the rights or privileges of the holders of such Shares or other securities on deposit may be substantially affected. Notwithstanding the foregoing, the Depositary will, if Sony Corporation so requests in writing, represent all securities on deposit (whether or not voting instructions have been received from holders thereof) for the sole purpose of establishing quorum at a meeting of shareholders.

The ability of the Depositary to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. Sony Corporation cannot assure ADS holders that they will receive voting materials in time to enable them to return voting instructions to the Depositary in a timely manner.

Fees and charges

See “Item 12D. Description of Securities other than Equity Securities—American Depositary Shares” in Sony Corporation’s annual report on Form 20-F for the fiscal year ended March 31, 2020.

Amendment and termination

Sony Corporation may agree with the Depositary to modify the Deposit Agreement at any time without ADS holders’ consent. Sony Corporation undertakes to give holders 30 days’ prior notice of any modifications that would materially prejudice any of their substantial rights under the Deposit Agreement. Sony Corporation will not consider to be materially prejudicial to ADS holders’ substantial rights any modifications or supplements that are reasonably necessary for the ADSs to be registered under the Securities Act or to be eligible for book-entry settlement, in each case without imposing or increasing the fees and charges that ADS holders are required to pay. In addition, Sony Corporation may not be able to provide ADS holders with prior notice of any modifications or supplements that are required to accommodate compliance with applicable provisions of law.

An ADS holder who continues to hold ADSs after the modifications to the Deposit Agreement become effective will be bound by the modifications to the Deposit Agreement. The Deposit Agreement cannot be amended to prevent a holder of ADSs from withdrawing the Shares represented by the holder’s ADSs (except as permitted by law).

Sony Corporation has the right to direct the Depositary to terminate the Deposit Agreement. Similarly, the Depositary may in certain circumstances on its own initiative terminate the Deposit Agreement. In either case, the Depositary must give notice to ADS holders at least 30 days before termination. Until termination, ADS holders’ rights under the Deposit Agreement will be unaffected.

After termination, the Depositary will continue to collect distributions received (but will not distribute any such property until ADS holders request the cancellation of their ADSs) and may sell the securities held on deposit. After the sale, the Depositary will hold the proceeds from such sale and any other funds then held for the holders of ADSs in a non-interest bearing account. At that point, the Depositary will have no further obligations to ADS holders other than to account for the funds then held for the holders still outstanding (after deduction of applicable fees, taxes and expenses) and as may be required at law in connection with the termination of the Deposit Agreement.

Books of Depositary

The Depositary maintains ADS holder records at its depositary office. A holder of ADSs may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the ADSs and the Deposit Agreement.

The Depositary maintains in New York facilities to record and process the issuance, cancellation, combination, split-up and transfer of ADSs. These facilities may be closed from time to time, to the extent not prohibited by law.

Limitations on obligations and liabilities

The Deposit Agreement limits Sony Corporation’s obligations and the Depositary’s obligations to holders of ADSs. Please note the following:

Sony Corporation and the Depositary, and their respective directors, officers, employees, agents and affiliates, are obligated only to take the actions specifically stated in the Deposit Agreement without negligence or bad faith.

 

•

Sony Corporation and the Depositary, and their respective controlling persons, directors, officers, employees agents, and affiliates, disclaim any liability for any failure of the Depositary to carry out voting instructions, for any manner in which a vote is cast or for the effect of any vote, provided it acts in good faith and in accordance with the terms of the Deposit Agreement.

 

•

Sony Corporation and the Depositary disclaim any liability for any failure to determine the lawfulness or practicality of any action, for the investment risks associated with investing in Shares or other deposited property, for the validity or worth of the Shares or other deposited property, for any tax consequences that result from the ownership of ADSs, Shares or other deposited property, for the credit-worthiness of any third party, for allowing any rights to lapse under the terms of the Deposit Agreement, for the timeliness of any of Sony Corporation’s notices or for Sony Corporation’s failure to give notice, or for any action of or failure to act by, or any information provided or not provided by, DTC or any DTC Participant.

---

•

The Depositary disclaims any liability for the content of any document forwarded to holders of ADSs on Sony Corporation’s behalf or for the accuracy of any translation of such a document.

 

•

Sony Corporation and the Depositary will not be obligated to perform any act that is inconsistent with the terms of the Deposit Agreement.

 

•

Sony Corporation and the Depositary disclaim any liability if Sony Corporation or the Depositary are prevented or forbidden from or subject to any civil or criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the Deposit Agreement, by reason of any provision, present or future of any law or regulation, or by reason of present or future provision of Sony Corporation’s Articles of Incorporation, or any provision of or governing the securities on deposit, or by reason of any act of God or war or other circumstances beyond Sony Corporation’s control.

 

•

Sony Corporation and the Depositary disclaim any liability by reason of any exercise of, or failure to exercise, any discretion provided for in the Deposit Agreement or in Sony Corporation’s Articles of Incorporation or in any provisions of or governing the securities on deposit.

 

•

Sony Corporation and the Depositary further disclaim any liability for any action or inaction in reliance on the advice or information received from legal counsel, accountants, any person presenting Shares for deposit, any holder of ADSs or authorized representatives thereof, or any other person believed by either of Sony Corporation or the Depositary in good faith to be competent to give such advice or information.

 

•

Sony Corporation and the Depositary also disclaim liability for the inability by a holder to benefit from any distribution, offering, right or other benefit that is made available to holders of Shares but is not, under the terms of the Deposit Agreement, made available to holders of ADSs.

 

•

Sony Corporation and the Depositary also disclaim liability for any consequential or punitive damages (including lost profits) for any breach of the terms of the Deposit Agreement.

 

•

Sony Corporation and the Depositary, and their controlling persons and agents, may rely without any liability upon any written notice, request or other document reasonably believed to be genuine and to have been signed or presented by the proper parties.

 

•

No disclaimer of liability under the Securities Act is intended by any provision of the Deposit Agreement.

 

•

Nothing in the Deposit Agreement gives rise to a partnership or joint venture, or establishes a fiduciary relationship, among Sony Corporation, the Depositary and ADS holders.

 

•

Nothing in the Deposit Agreement precludes the Depositary (or its affiliates) from engaging in transactions in which parties adverse to Sony Corporation or the ADS owners have interests, and nothing in the Deposit Agreement obligates the Depositary to disclose those transactions, or any information obtained in the course of those transactions, to Sony Corporation or to the ADS owners, or to account for any payment received as part of those transactions.

Taxes

Holders of ADSs will be responsible for the taxes and other governmental charges payable on the ADSs and the securities represented by the ADSs, and Sony Corporation will have no liability therefor. Sony Corporation, the Depositary and the Custodian may deduct from any distribution the taxes and governmental charges payable by holders and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders. ADS holders will be liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The Depositary may refuse to issue ADSs, to deliver, transfer, split and combine ADRs or to release securities on deposit until all taxes and charges are paid by the applicable holder. The Depositary and the Custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on an ADS holder’s behalf. However, an ADS holder may be required to provide to the Depositary and to the Custodian proof of taxpayer status and residence and such other information as the Depositary and the Custodian may require to fulfill legal obligations. An ADS holder is required to indemnify Sony Corporation, the Depositary and the Custodian for any claims with respect to taxes based on any tax benefit obtained for the holder.

Foreign currency conversion

As soon as reasonably practicable, the Depositary will arrange for the conversion of all foreign currency received into U.S. dollars if in the reasonable judgment of the Depositary such conversion is practicable, and it

---

will distribute the U.S. dollars in accordance with the terms of the Deposit Agreement. An ADS holder may have to pay any applicable fees, any reasonable and customary expenses incurred in converting foreign currency, and any expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practicable or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the Depositary may take the following actions in its reasonable discretion:

 

•

Convert the foreign currency to the extent practicable and lawful and distribute the U.S. dollars to the holders for whom the conversion and distribution is lawful and practicable;

 

•

Distribute the foreign currency to holders for whom the distribution is lawful and practicable; or

 

•

Hold the foreign currency (without liability for interest) for the applicable holders.

Governing law

The Deposit Agreement and the ADRs will be interpreted in accordance with the laws of the State of New York. The rights of holders of Shares (including Shares represented by ADSs) are governed by the laws of Japan.

Ownership restrictions

Sony Corporation may restrict, in such manner as it deems appropriate, transfers of ADSs where such transfer might result in the total number of Shares represented by ADSs owned by a single ADS holder exceeding any limits imposed by applicable law or Sony Corporation’s Articles of Incorporation. Sony Corporation may also, in its sole discretion but subject to applicable law, instruct the Depositary to take certain actions with respect to the ownership interest of any ADS holder in excess of these limits.

The Financial Instruments and Exchange Act of Japan, and other applicable Japanese law, require any ADS holder who becomes, or ceases to be, directly or indirectly, the beneficial owner of more than 5% of all outstanding Shares (whether such interest is held in whole or only in part through ADRs) to, within five business days following such event, send written notice to the Depositary at its Transfer Office and to Sony Corporation at its principal office in Japan currently at 7-1, Konan 1-chome, Minato-ku, Tokyo 108-0075, Japan, Attention: Investor Relations Department. For more details on the information that must be included in the notice, please refer to the Deposit Agreement. A similar notice must also be filed in respect of any subsequent change of 1% or more in any such holding, or any change in material matters set out in notices previously filed. In addition, the Foreign Exchange and Foreign Trade Act of Japan and its related cabinet orders and ministerial ordinances govern certain aspects relating to the holding of ADSs and the exercise of voting rights by an ADS holder who falls into the definition of “foreign investor” that constitute an “inward direct investment”, as described in more detail in “Item 10D. Exchange Controls” of Sony Corporation’s annual report on Form 20-F for the fiscal year ended March 31, 2020.

An ADS holder shall, if so requested in writing by Sony Corporation, provide such information with respect to the beneficial ownership of Shares as is requested.

If Sony Corporation notifies the Depositary in writing that a particular ADS holder has not complied with the requirements above, at Sony Corporation’s written request the Depositary will instruct the ADS holder to surrender its ADSs for cancellation so as to permit Sony Corporation to deal directly with the ADS holder as a shareholder of Sony Corporation.

Acquisitions	12 Months Ended
	Mar. 31, 2020
Business Combinations [Abstract]
Acquisitions	25. Acquisitions             (1) EMI Music Publishing acquisition             On November 14, 2018, Sony Corporation of America, Sony’s wholly-owned subsidiary, completed the acquisition of the entirety of the approximately 60% equity interest held by the investor consortium led by the Mubadala Investment Company in DH Publishing, L.P. (“EMI”), which owned and managed EMI Music Publishing, for the equity purchase price of 257,168 million yen (2,269 million U.S. dollars), which includes payments related to warrants and management equity plans. Sony paid all the consideration in cash upon the acquisition. As a result of this acquisition, EMI has become a wholly-owned subsidiary of Sony. This acquisition allows Sony to build upon its music publishing library by providing the Company with full ownership of the EMI Music Publishing catalog which was being administered by Sony’s wholly-owned music publishing subsidiary, Sony/ATV Music Publishing. Sony’s consolidated income statements for the fiscal year ended March 31, 2019 include revenue and operating income of 28,871 million yen (260 million U.S. dollars) and 6,432 million yen (58 million U.S. dollars), respectively, attributable to EMI since the date of acquisition. Sony’s consolidated income statements for the three months ended March 31, 2019 include revenue and operating income of 18,420 million yen (167 million U.S. dollars) and 4,522 million yen (41 million U.S. dollars), respectively, attributable to EMI. Prior to the acquisition, Sony’s interest in EMI was accounted for under the equity method of accounting. As a result of Sony obtaining a controlling interest in EMI, Sony consolidated EMI using the acquisition method of accounting and recorded the fair value of the identifiable assets, liabilities assumed and residual goodwill of EMI. Sony remeasured the approximately 40% equity interest in EMI that Sony already owned prior to the acquisition at a fair value of 141,141 million yen (1,245 million U.S. dollars) which resulted in the recognition of a non-cash gain of 116,939 million yen (1,032 million U.S. dollars) recorded in other operating income, net for the three months ended December 31, 2018. Sony did not record any tax expense or deferred tax liability corresponding to this gain. Sony also assumed EMI’s existing interest-bearing debt of 148,621 million yen (1,311 million U.S. dollars) as a result of this acquisition, of which 108,942 million yen (961 million U.S. dollars) was repaid immediately from Sony’s existing cash. The following table summarizes the preliminary and final fair values assigned to the assets and liabilities of EMI that were recorded in the Music segment. Certain areas of the purchase price allocation were not yet finalized as of the fiscal year ended March 31, 2019, including the valuation of income taxes and residual goodwill.                             Yen in millions     Acquired assets and liabilities recorded at fair value as of acquisition date (Preliminary)     Measurement period adjustments     Acquired assets and liabilities recorded at fair value as of acquisition date (Final)   Cash and cash equivalents     12,971             12,971   Notes and accounts receivable, trade and contract assets     32,287             32,287   Prepaid expenses and other current assets     10,220       (98 )     10,122   Securities investments and other     1,476             1,476   Intangibles, net     420,534             420,534   Goodwill     237,271       (1,206 )     236,065   Other     10,023             10,023                             Total assets     724,782       (1,304 )     723,478                             Notes and accounts payable, trade     1,731             1,731   Accounts payable, other and accrued expenses     70,675             70,675   Accrued income and other taxes     3,082       (69 )     3,013   Long-term debt     148,621             148,621   Accrued pension and severance costs     1,947             1,947   Deferred income taxes     94,849       (1,235 )     93,614   Other     5,564             5,564                             Total liabilities     326,469       (1,304 )     325,165                                       Intangibles mainly consists of music publishing catalogs with weighted average amortization periods of 43 years. Goodwill represents unidentifiable intangible assets, such as future growth from new revenue streams and synergies with existing Sony assets and businesses, and is calculated as the excess of the purchase price over the estimated fair value of the tangible and intangible assets acquired and is not deductible for tax purposes. The goodwill recorded in connection with this acquisition is included in the Music segment. The following unaudited supplemental pro forma financial information presents the combined results of operations of Sony and EMI as though the acquisition had occurred as of the beginning of the fiscal year ended March 31, 2018:                      Yen in millions, Yen per share amounts     Fiscal year ended March 31     2018     2019   Net sales     8,612,280       8,738,209   Operating income     854,786       801,973   Net income attributable to Sony Corporation’s stockholders     584,019       817,629   Per share data:             — Basic EPS     462.08       645.53   — Diluted EPS     451.88       631.55             The unaudited supplemental pro forma financial information is based on estimates and assumptions, which Sony believes are reasonable, and is not intended to represent or be indicative of what Sony’s consolidated net income attributable to Sony Corporation’s stockholders would have been had the acquisition been completed at the beginning of the fiscal year ended March 31, 2018 and should not be taken as indicative of Sony’s future consolidated net income attributable to Sony Corporation’s stockholders. The unaudited supplemental pro forma financial information includes the elimination of equity in net income and consolidation of EMI, the adjustment of the gain from the remeasurement of the previously owned equity interest, incremental intangible asset amortization, net of the related tax effects and the adjustments of expenses incurred in relation to warrants and management equity plans. (2) Insomniac Games, Inc. acquisition           On November 15, 2019, Sony Interactive Entertainment LLC, a wholly-owned subsidiary in the G&NS segment of Sony, completed the acquisition of Insomniac Games, Inc. (“Insomniac Games”), a game developer. The consideration for this acquisition of 24,895 million yen (229 million U.S. dollars) was mainly paid in cash. As a result of this acquisition, Insomniac Games has become a wholly-owned subsidiary of Sony. As a result of this acquisition, Sony recorded 17,945 million yen (164 million U.S. dollars) of goodwill and 6,794 million yen (62 million U.S. dollars) of intangible assets. The cash consideration paid in this transaction, net of cash received, is included within Other in the investing activities section of the consolidated statements of cash flows. Pro forma results of operations have not been presented because the effect of the acquisition was not material. (3) Silvergate Media acquisition           On December 9, 2019, Sony, through a wholly-owned subsidiary in the Pictures segment, acquired Silvergate Media Group (“Silvergate”), a company focused on developing, producing and licensing children’s animation. The consideration for this acquisition of 21,017 million yen (192 million U.S. dollars) was paid in cash. As a result of this acquisition, Sony owns (1) 100% of Silvergate Topco Limited, which holds all assets of Silvergate other than certain rights held by Silvergate BP Bidco Limited, and (2) 31% of Silvergate BP Bidco Limited, the entity through which Silvergate produces its Peter Rabbit television series, and Sony recorded 11,431 million yen (106 million U.S. dollars) of goodwill and 3,387 million yen (32 million U.S. dollars) of intangible assets. The cash consideration paid in this transaction, net of cash received, is included within Other in the investing activities section of the consolidated statements of cash flows. Pro forma results of operations have not been presented because the effect of the acquisition was not material. (4) Acquisition of equity interests in joint ventures in the life insurance business           On January 29, 2020, Sony Life, Sony’s consolidated subsidiary, acquired 50% of the shares of AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. (collectively, the “JVs”) from AEGON International B.V. The purchase price for the acquisition was 18,750 million yen and Sony Life paid all the consideration in cash upon the acquisition. As a result of this acquisition, Sony Life owns 100% of the shares of the JVs and the JVs have become consolidated subsidiaries of Sony. Sony Life will endeavor to make use of the strength and know-how of the variable annuity business accumulated by AEGON Sony Life Insurance Co., Ltd, strengthen the initiatives for the senior market, and improve earnings in an early stage by enhancing efficiency through integrated operation and organizational management. AEGON Sony Life Insurance Co., Ltd. has changed its name to “Sony Life With Insurance Co., Ltd.,” as of April 1, 2020. Prior to the acquisition, Sony’s interest in the JVs was accounted for under the equity method of accounting. As a result of Sony obtaining a controlling interest in the JVs, Sony consolidated the JVs using the acquisition method of accounting and recorded the fair value of the identifiable assets, liabilities assumed and residual goodwill of the JVs. Sony remeasured the 50% equity interest in the JVs that Sony already owned prior to the acquisition at a fair value of 13,932  million yen which resulted in the recognition of a non-cash gain of 1,827  million yen recorded in other operating income, net. Sony did not record any tax expense or deferred tax liability corresponding to this gain. The following table summarizes the fair values assigned to the assets and liabilities of the JVs that were recorded in the Financial Services segment.             Yen in millions   Cash and cash equivalents     27,380   Marketable securities     530,851   Prepaid expenses and other current assets     21,933   Securities investments and other     15,329   Goodwill     3,609   Other     406             Total assets     599,508             Future insurance policy benefits and other     66,599   Policyholders’ account in the life insurance business     495,248   Other     4,979             Total liabilities     566,826                   Goodwill represents the expected improvement of profitability due to business integration with Sony Life and operational efficiency, and is calculated as the excess of the purchase price over the estimated fair value of the tangible and intangible assets acquired and is not deductible for tax purposes. The goodwill recorded in connection with this acquisition is included in the Financial Services segment. Pro forma results of operations have not been presented because the effect of the acquisition was not material. (5) Other acquisitions       During the fiscal year ended March 31, 2018, Sony completed other acquisitions for total consideration of 27,459 million yen which were paid for primarily in cash and there was no material contingent consideration subject to future change.

Segment Reporting [Abstract]
Business segment information	29. Business segment information       The reportable segments presented below are the segments of Sony for which separate financial information is available and for which operating profit or loss amounts are evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The CODM does not evaluate segments using discrete asset information. Sony’s CODM is its Chief Executive Officer and President. Sony realigned its business segments from the first quarter of the fiscal year ended March 31, 2020 to reflect modifications to the organizational structure of certain segments and a change in the Senior Executives in charge of certain segments as of April 1, 2019. In connection with this decision, the former Home Entertainment & Sound, Imaging Products & Solutions and Mobile Communications segments have been realigned as the EP&S segment. In connection with this realignment, the sales and operating revenue and operating income (loss) of each segment for the comparative periods have been reclassified to conform to the current presentation. In addition, the former Semiconductors segment has been renamed the I&SS segment effective from the first quarter of the fiscal year ended March 31, 20 20. The G&NS segment includes network services businesses, the manufacture and sales of home gaming products and production and sales of software. The Music segment includes the Recorded Music, Music Publishing and Visual Media and Platform businesses. The Pictures segment includes the Motion Pictures, Television Productions and Media Networks businesses. The EP&S segment includes the Televisions business, the Audio and Video business, the Still and Video Cameras business, the smartphone business and Internet-related service business. The I&SS segment includes the image sensors business. The Financial Services segment primarily represents individual life insurance and non-life insurance businesses in the Japanese market and a bank business in Japan. All Other consists of various operating activities, including the disc manufacturing and recording media businesses. Sony’s products and services are generally unique to a single operating segment.

Insurance-related accounts	12 Months Ended

Insurance [Abstract]
Insurance-related accounts	10. Insurance-related accounts           Sony’s Financial Services segment subsidiaries in Japan maintain their accounting records as described in Note 2 in accordance with the accounting principles and practices generally accepted in Japan, which vary in some respects from U.S. GAAP. Those differences are mainly that insurance acquisition costs for life and non-life insurance contracts are charged to income when incurred in Japan whereas in the United States those costs are deferred and amortized generally over the premium-paying period of the related insurance policies, and that future policy benefits for life insurance contracts calculated locally under the authorization of the supervisory administrative agencies are comprehensively adjusted using mainly the net level premium method with certain adjustments of actuarial assumptions for U.S. GAAP purposes. For the purpose of preparing the consolidated financial statements, appropriate adjustments have been made to reflect the accounting for these items in accordance with U.S. GAAP. The combined amounts of statutory net equity of the insurance subsidiaries, which is not measured in accordance with U.S. GAAP, as of March 31, 2019 and 2020 were 548,730 million yen and 586,983 million yen, respectively. (1) Insurance policies                       Life insurance policies that subsidiaries in the Financial Services segment underwrite, most of which are categorized as long-duration contracts, mainly consist of whole life, term life and accident and health insurance contracts. The life insurance revenues for the fiscal years ended March 31, 2018, 2019 and 2020 were 857,766 million yen, 910,011 million yen and 1,052,316 million yen, respectively. Property and casualty insurance policies that a subsidiary in the Financial Services segment underwrites are primarily automotive insurance contracts, which are categorized as short-duration contracts. The non-life insurance revenues for the fiscal years ended March 31, 2018, 2019 and 2020 were 105,497 million yen, 111,392 million yen and 115,730 million yen, respectively. (2) Deferred insurance acquisition costs                       Amortization of deferred insurance acquisition costs charged to income for the fiscal years ended March 31, 2018, 2019 and 2020 amounted to 68,137 million yen, 79,906 million yen and 93,734 million yen, respectively. At March 31, 2019 and 2020, the balances of deferred insurance acquisition costs of non-traditional life insurance contracts were 209,897 million yen and 206,363 million yen, respectively. (3) Future insurance policy benefits                       Liabilities for future insurance policy benefits, except the portion of liabilities for minimum guarantee benefits which is described below, which mainly relate to individual life insurance policies, are established in amounts adequate to meet the estimated future obligations of policies in force. These liabilities, which require significant management judgment and estimates, are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. Future policy benefits are computed using interest rates ranging from 0.5% to 4.5% and are based on factors such as market conditions and expected investment returns. Morbidity, mortality and withdrawal assumptions for all policies are based on either the subsidiary’s own experience or various actuarial tables. Generally these assumptions are locked-in throughout the life of the contract upon the issuance of new insurance, although significant changes in experience or assumptions may require Sony to provide for expected future losses.  Liabilities for future policy benefits includes the liabilities for the minimum guarantee benefits of variable annuities and variable life insurance contracts. The details regarding the minimum guarantee benefits are presented in (5) below. Sony elected the fair value option for certain of these liabilities for future insurance policy benefits. Refer to Note 13. At March 31, 2019 and 2020, future insurance policy benefits amounted to 5,633,865 million yen and 6,237,048 million yen, respectively. (4) Policyholders’ account in the life insurance business                       Policyholders’ account in the life insurance business represents an accumulation of account deposits plus credited interest less withdrawals, expenses and mortality charges. Policyholders’ account includes universal life insurance and investment contracts. Universal life insurance includes interest sensitive whole life contracts and variable   life insurance contracts. The credited rates associated with interest sensitive whole life contracts range from 1.7% to 2.0%. For variable life insurance   contracts, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. Investment contracts mainly include single payment endowment contracts, single payment educational endowment contracts, individual variable annuities and policies after the start of annuity payments. The credited rates associated with investment contracts, except for individual variable annuities, range from 0.01% to 6.3%. For individual variable annuities, policy values are expressed in terms of investment units. Each unit is linked to an asset portfolio. The value of a unit increases or decreases based on the value of the linked asset portfolio. The liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business. Refer to Note 13. Policyholders’ account in the life insurance business is comprised of the following:                     Yen in millions     March 31     2019     2020   Universal life insurance     2,104,646       2,611,577   Investment contracts     816,903       885,690   Other     126,653       145,004                     Total     3,048,202       3,642,271                                         (5) Minimum guarantee benefit for variable annuities and variable life insurance contracts                       Regarding variable annuities and variable life insurance contracts, minimum guarantee benefits (minimum death benefit, minimum accumulation benefit, etc.) are provided, and Sony bears the risk of fulfilling the minimum guarantee benefits prescribed in the contracts to policyholders. The fair value option is applied to the portion of the liability for variable annuity contracts with minimum guarantee benefits. Refer to Note 13. Excluding the portion of the liability measured at fair value, the liability for the minimum guarantee benefit is calculated based on the ratio of the present value of expected total excess payments divided by the present value of expected total assessments over the life of the contract. Mortality rates, lapse rates, discount rates and investment yield are used as significant assumptions for this calculation.   The policyholders’ account value, net amount at risk, liability for the minimum guarantee benefit, and average attained age at March 31, 2019 and 2020 are as follows.                             Yen in million s     March 31, 2019     Variable annuities     Variable life  insurance contracts     Total   Policyholder s ’ account value     —       1,092,559       1,092,559   Net amount at risk     —       4,334,224       4,334,224   Liability for minimum guarantee benefit     —       63,423       63,423                         Age       March 31 2019         Variable annuities     Variable life insurance contracts   Average attained age     —       44                                                   Yen in million s     March 31 ,  2020     Variable annuities     Variable life  insurance contracts     Total   Policyholder s ’ account value     464,093       1,096,935       1,561,028   Net amount at risk     71,685       4,564,214       4,635,899   Liability for minimum guarantee benefit     64,045       79,860       143,905                         Age         March 31 2020         Variable annuities     Variable life insurance contracts   Average attained age     60       45

Transfer of financial assets	6. Transfer of financial assets                               Sony has established several accounts receivable sales programs mainly within the EP&S segment. Through these programs, Sony can sell receivables to a commercial bank or a special purpose entity associated with a sponsor bank. Total receivables sold during the fiscal years ended March 31, 2018, 2019 and 2020 were 84,718 million yen, 81,947 million yen and 65,214 million yen, respectively. These transactions are accounted for as sales in accordance with the accounting guidance for transfers of financial assets, because Sony has relinquished control of the receivables. Sony includes the sales proceeds from these receivables as cash flows within operating activities in the consolidated statement of cash flows because the receivables are the result of operating activities and are short term in nature. Gains and losses from these transactions were insignificant. Although Sony continues servicing the receivables subsequent to being sold or contributed, no servicing assets or liabilities are recorded as the costs of collection of the sold receivables and the income from servicing such receivables are insignificant. Certain accounts receivable sales programs above also involve VIEs. Refer to Note 24.

Accounting Policies [Abstract]
Summary of significant accounting policies	2 . Summary of significant accounting policies         The accompanying consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Certain adjustments and reclassifications have been incorporated in the accompanying consolidated financial statements to conform with U.S. GAAP. These adjustments were not recorded in the statutory books and records as Sony Corporation and its subsidiaries in Japan maintain their records and prepare their statutory financial statements in accordance with accounting principles generally accepted in Japan, while its foreign subsidiaries maintain their records and prepare their financial statements in conformity with accounting principles generally accepted in the countries of their domicile. (1) Significant accounting policies Basis of consolidation and accounting for investments in affiliated companies - The consolidated financial statements include the accounts of Sony Corporation and its majority-owned subsidiary companies, general partnerships and other entities in which Sony has a controlling interest, and variable interest entities (“VIEs”) for which Sony is the primary beneficiary. All intercompany transactions and accounts are eliminated. Investments in business entities in which Sony does not have control, but has the ability to exercise significant influence over operating and financial policies, generally through 20-50% ownership, are accounted for under the equity method. In addition, investments in general partnerships in which Sony does not have a controlling interest and limited partnerships are also accounted for under the equity method if more than minor influence over the operation of the investee exists (generally through more than 3-5% ownership). When the interest in the partnership is so minor that Sony has no significant influence over the operation of the investee, the interest in the partnership is carried at fair value. Under the equity method, investments are stated at cost plus/minus Sony’s portion of equity in undistributed earnings or losses. Sony’s equity in current earnings or losses of such entities is reported net of income taxes and is included in operating income (loss) after the elimination of unrealized intercompany profits. If the value of an investment has declined and is judged to be other-than-temporary, the investment is written down to its estimated fair value. On occasion, a consolidated subsidiary or an affiliated company accounted for by the equity method may issue its shares to third parties in either a public or private offering or upon conversion of convertible debt to common stock at amounts per share in excess of or less than Sony’s average per share carrying value. With respect to such transactions, the resulting gains or losses arising from the change in ownership interest are recorded in earnings within the fiscal year in which the change in interest transactions occurs. Gains or losses that result from a loss of a controlling financial interest in a subsidiary are recorded in earnings along with fair value remeasurement gains or losses on any retained investment in the entity, while a change in interest in a consolidated subsidiary that does not result in a change in control is accounted for as a capital transaction and no gains or losses are recorded in earnings. The excess of the cost over the underlying net equity of investments in consolidated subsidiaries and affiliated companies accounted for on an equity basis is allocated to identifiable tangible and intangible assets and liabilities based on fair values at the date of acquisition. The unassigned residual value of the excess of the cost over Sony’s underlying net equity is recognized as goodwill as a component of the investment balance. Use of estimates - The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include those used in determining the valuation of investment securities, valuation of inventories, fair values of long-lived assets, fair values of goodwill and other intangible assets, fair values of assets and liabilities assumed in business combinations, product warranty liability, pension and severance plans, valuation of deferred tax assets, uncertain tax positions, film costs, and insurance related liabilities. Actual results could significantly differ from those estimates. The timing and extent to which the spread of COVID-19 may negatively impact Sony’s business will depend on future developments, which are highly uncertain. This uncertainty could result in greater variability in accounting estimates and assumptions, including, but not limited to, those used in reviewing goodwill and long-lived assets for impairment and the valuation of deferred tax assets. Translation of foreign currencies - All asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at appropriate fiscal year end exchange rates and all income and expense accounts are translated at exchange rates that approximate those rates prevailing at the time of the transactions. The resulting translation adjustments are accumulated as a component of accumulated other comprehensive income. Upon remeasurement of a previously held equity interest in accordance with the accounting guidance for business combinations achieved in stages, accumulated translation adjustments, if any, are included in earnings. Monetary assets and liabilities denominated in foreign currencies are translated at appropriate fiscal year end exchange rates and the resulting translation gains or losses are recognized into income. Cash, cash equivalents and restricted cash - Cash and cash equivalents include all highly liquid investments, with original maturities of three months or less, that are readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates. Sony includes restricted cash within cash and cash equivalents in the statement of cash flows. Marketable debt and equity securities - Debt securities designated as available-for-sale are carried at fair value with unrealized gains or losses included as a component of accumulated other comprehensive income, net of applicable taxes. Equity securities that have a readily determinable fair value, and debt securities classified as trading securities, are carried at fair value with unrealized gains or losses included in income. Debt securities that are expected to be held-to-maturity are carried at amortized cost. Individual securities classified as either available-for-sale or held-to-maturity are reduced to fair value by a charge to income when an other-than-temporary impairment is recognized. Realized gains and losses are determined on the average cost method and are reflected in income. Sony regularly evaluates its investment portfolio to identify other-than-temporary impairments of individual debt securities. Factors that are considered by Sony in determining whether an other-than-temporary decline in value has occurred include: the length of time and extent to which the market value of the security has been less than its original cost, the financial condition, operating results, business plans and estimated future cash flows of the issuer of the security, other specific factors affecting the market value, deterioration of the credit condition of the issuer, sovereign risk, and whether or not Sony is able to retain the investment for a period of time sufficient to allow for the anticipated recovery in market value. In evaluating the factors for debt securities designated as available-for-sale, Sony presumes a decline in value to be other-than-temporary if the fair value of the security is 20 percent or more below its original cost for an extended period of time (generally for a period of up to six months). This criterion is employed as a threshold to identify securities which may have a decline in value that is other-than-temporary. The presumption of an other-than-temporary impairment in such cases may be overcome if there is evidence to support that the decline is temporary in nature due to the existence of other factors which overcome the duration or magnitude of the decline. On the other hand, there may be cases where impairment losses are recognized when the decline in the fair value of the security is not more than 20 percent or such decline has not existed for an extended period of time, as a result of considering specific factors which may indicate that the decline in the fair value is other-than-temporary. When an other-than-temporary impairment of a held-to-maturity debt security has occurred, the amount of the other-than-temporary impairment recognized in income depends on whether Sony intends to sell the debt security or more likely than not will be required to sell the debt security before recovery of its amortized cost. If the debt security meets either of these two criteria, the other-than-temporary impairment is recognized in income, measured as the entire difference between the security’s amortized cost and its fair value at the impairment measurement date. For other-than-temporary impairment of the debt security that does not meet these two criteria, the net amount recognized in income is a credit loss, which equals the difference between the amortized cost of the debt security and its net present value calculated by discounting Sony’s best estimate of projected future cash flows at the effective interest rate implicit in the debt security prior to impairment. Any difference between the fair value and the net present value of the debt security at the impairment measurement date is recorded in accumulated other comprehensive income. Unrealized gains or losses on securities for which an other-than-temporary impairment is recognized in income are presented as a separate component of accumulated other comprehensive income. Equity securities that do not have readily determinable fair values - Equity securities that do not have readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. If the value of equity securities that do not have readily determinable fair values is estimated to have declined and such decline is judged to be other-than-temporary, Sony recognizes the impairment of the investment and the carrying value is reduced to its fair value. Determination of impairment is based on the consideration of several factors, including operating results, business plans and estimated future cash flows. Fair value is determined through the use of various methodologies such as discounted cash flows, valuation of recent financings and comparable valuations of similar companies. Allowance for doubtful accounts - Sony maintains an allowance for doubtful accounts to reserve for potentially uncollectible receivables. Sony reviews accounts receivable by amounts due from customers which are past due to identify specific customers with known disputes or collectability issues. In determining the amount of the reserve, Sony makes judgments about the creditworthiness of customers based on past collection experience and ongoing credit risk evaluations. Inventories - Inventories in the Game & Network Services (“G&NS”), Music, Electronics Products & Solutions (“EP&S”) and Imaging & Sensing Solutions (“I&SS”) segments as well as non-film inventories for the Pictures segment are valued at cost, not in excess of the net realizable value – i.e., estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal, cost being determined on the “average cost” basis. Other receivables - Other receivables include receivables which relate to arrangements with certain component manufacturers whereby Sony procures goods, including product components, for these component manufacturers and is reimbursed for the related purchases. No revenue or profit is recognized on these transfers. Sony will repurchase the inventory at a later date from the component manufacturers as either finished goods inventory or as partially assembled product. Film costs - Film costs include direct production costs, production overhead and acquisition costs for both motion picture and television productions and are stated at the lower of unamortized cost or estimated fair value and classified as noncurrent assets. Film costs are amortized, and the estimated liabilities for residuals and participations are accrued using an individual-film-forecast method based on the ratio of current period actual revenues to the estimated remaining total revenues. Film costs also include broadcasting rights, which are recognized when the license period begins and the program is available for use, and consist of acquired programming to be aired on Sony’s worldwide channel network. Broadcasting rights are stated at the lower of unamortized cost or net realizable value, classified as either current or noncurrent assets based on timing of expected use. Broadcasting rights are amortized based on estimated usage or on a straight-line basis over the useful life, as appropriate, although broadcasting rights licensed under multi-year live-event sports programming agreements are generally amortized based on the ratio of the current period’s actual advertising revenue and an allocation of subscription fee revenue to the estimated total remaining attributable revenues. Estimates used in calculating the fair value of film costs and the net realizable value of broadcasting rights are based upon assumptions about future demand and market conditions and are reviewed on a periodic basis. Property, plant and equipment and depreciation - Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method. Useful lives for depreciation range from 2 to 50 years for buildings and from 2 to 10 years for machinery and equipment. Significant renewals and additions are capitalized at cost. Maintenance and repairs, and minor renewals and betterments are charged to income as incurred. Leases - When entering into a contract, Sony determines whether an arrangement contains a lease at its inception. An arrangement contains a lease if it conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Operating leases are included in operating lease right-of-use assets, current portion of long-term operating lease liabilities, and long-term operating lease liabilities on Sony’s consolidated balance sheets. Finance leases are included in finance lease right-of-use assets, current portion of long-term debt, and long-term debt on Sony’s consolidated balance sheets. Right-of-use assets represent Sony’s right to use an underlying asset for the lease term and lease liabilities represent Sony’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Right-of-use assets also include any lease payments or initial direct costs incurred on or before the commencement date and excludes lease incentives. In determining the present value of lease payments, Sony generally uses its incremental borrowing rate, as the implicit rate is not available for most of its leases. Sony determines its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing, taking into account the lease term and the economic environment of each country or region at commencement date. The lease terms include options to extend or terminate the lease when it is reasonably certain that Sony will exercise that option. Lease expense for operating leases recorded on the balance sheet is recognized on a straight-line basis over the lease term. Sony accounts for the lease and non-lease components of all underlying asset classes as a single lease component. Sony has applied the short-term lease exception for leases with a term of one year or less, where right-of-use assets and lease liabilities are not recognized and the expense is recognized on a straight-line basis . As of April 1, 2019, Sony adopted Accounting Standards Update (“ASU”) 2016-02, which amends leasing guidance, on a modified retrospective basis with no restatement of comparative periods. Prior to the adoption of ASU 2016-02 on April 1, 2019, right-of-use assets and lease liabilities for operating leases were not recognized in Sony’s consolidated balance sheet. For the detailed effect of the adoption of the new standard on Sony’s results of operations and financial position, refer to Note 2 (2) Recently adopted accounting pronouncements. Goodwill and other intangible assets - Goodwill and indefinite lived intangible assets are tested annually for impairment during the fourth quarter of the fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. Such an event or change in circumstances would include unfavorable variances from established business plans, significant changes in forecasted results or volatility inherent to external markets and industries, which are periodically reviewed by Sony’s management. In the fourth quarter of the fiscal year ended March 31, 2020, Sony elected not to perform an optional qualitative assessment of goodwill and instead proceeded directly to a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. Reporting units are Sony’s operating segments or one level below the operating segments. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the total amount of goodwill allocated to the reporting unit. Indefinite lived intangible assets are tested for impairment by comparing the fair value of the intangible asset with its carrying value, and if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The fair value of a reporting unit or indefinite lived intangible asset is generally determined using a discounted cash flow analysis. This approach uses significant estimates and assumptions, including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, earnings multiples, the determination of appropriate comparable entities and the determination of whether a premium or discount should be applied to comparables. Consideration is also given to Sony’s market capitalization in relation to the sum of the calculated fair values of the reporting units, including reporting units with no goodwill, and taking into account corporate level assets and liabilities not assigned to individual reporting units as well as a reasonable control premium. The assumptions used for projected future cash flows and the timing of such cash flows are based on the forecast and mid-range plan (“MRP”) of each reporting unit and take into account such factors as historical experience, market and industry information, and current and forecasted economic conditions. Perpetual growth rates are utilized to determine a terminal cash flow value and are generally set after the three-year forecasted period for the MRP. Certain reporting units, such as those in the Pictures segment, utilize longer forecast periods and base the terminal value on an exit price using an earnings multiple applied to the final year of the forecasted earnings, which also takes into consideration a control premium. Discount rates are derived from the weighted average cost of capital of market participants in similar businesses. Management believes that the assumptions used to estimate the fair value in the goodwill impairment tests are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower than currently anticipated cash flows and fair values due to unforeseen changes in assumptions could negatively affect the valuations, which may result in Sony recognizing impairment charges for goodwill and indefinite lived intangible assets in the future. When a business within a reporting unit is disposed of, goodwill is allocated to the disposed business using the relative fair value method. Intangible assets with finite useful lives mainly consist of patent rights, know-how, license agreements, customer relationships, trademarks, software to be sold, leased or otherwise marketed, internal-use software, music catalogs, artist contracts, and television carriage contracts (broadcasting agreements). Patent rights, know-how, license agreements, trademarks, software to be sold, leased or otherwise marketed, and internal-use software are generally amortized on a straight-line basis over 3 to 10 years. Customer relationships, music catalogs, artist contracts and television carriage contracts (broadcasting agreements) are generally amortized on a straight-line basis over 10 to 44 years. Capitalized software - The costs related to establishing the technological feasibility of software to be sold, leased or otherwise marketed are expensed as incurred as a part of research and development in cost of sales. Costs that are incurred to produce the finished product after technological feasibility is established are capitalized and amortized to cost of sales over the estimated economic life, which is generally three years. The technological feasibility of game software is established when the product master is completed. Consideration to capitalize game software development costs before this point is limited to the development costs of games for which technological feasibility can be proven at an earlier stage. At each balance sheet date, Sony performs reviews to ensure that unamortized capitalized software costs remain recoverable from future profits of the related software products. The costs incurred for internal-use software during the application development stage are capitalized and amortized, mainly to selling, general and administrative expenses, on a straight-line basis over the estimated useful life. Costs related to the preliminary project stage and post implementation activities are expensed as incurred. Deferred insurance acquisition costs - Costs that vary with and are directly related to the acquisition or renewal of insurance policies are deferred as long as they are recoverable. The deferred insurance acquisition costs include such items as commissions, medical examination costs and inspection report fees, and are subject to recoverability testing at least annually to ensure that the capitalized amounts do not exceed the present value of anticipated gross profits or premiums less benefits and maintenance expenses, as applicable. The deferred insurance acquisition costs for traditional life insurance contracts are amortized over the premium-paying period of the related insurance policies using assumptions consistent with those used in computing policy reserves. The deferred insurance acquisition costs for non-traditional life insurance contracts are amortized over the expected life at a constant rate based on the present value of the estimated gross profit. Investment yields, mortality rates, lapse rates and discount rates are used as important assumptions for the present value of the estimated gross profit. Product warranty - Sony provides for the estimated cost of product warranties at the time revenue is recognized. The product warranty is calculated based upon product sales, estimated probability of failure and estimated cost per claim. The variables used in the calculation of the provision are reviewed on a periodic basis. Future insurance policy benefits - Liabilities for future insurance policy benefits are primarily comprised of the present value of estimated future payments to policyholders. These liabilities are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. These assumptions are reviewed on a periodic basis. Liabilities for future policy benefits includes the liabilities for the minimum guarantee benefits of variable annuities and variable life insurance contracts. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for future insurance policy benefits. Policyholders’ account in the life insurance business - Liabilities for policyholders’ account in the life insurance business represent the contract value that has accrued to the benefit of the policyholders as of the balance sheet date. This liability is generally equal to the accumulated account deposits, plus interest credited, less policyholder withdrawals and other charges assessed against the account balances. Liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business. Impairment of long-lived assets - Sony reviews the recoverability of the carrying value of its long-lived assets held and used, other than goodwill and intangible assets with indefinite lives, and assets to be disposed of, whenever events or changes in circumstances indicate that the individual carrying amount of an asset or asset group may not be recoverable. Long-lived assets to be held and used are reviewed for impairment by comparing the carrying value of the asset or asset group with their estimated undiscounted future cash flows. If the cash flows are determined to be less than the carrying value of the asset or asset group, an impairment loss would be recognized during the period for the amount by which the carrying value of the asset or asset group exceeds estimated fair value. Long-lived assets that are to be disposed of other than by sale are considered held and used until they are disposed of. Long-lived assets that are to be disposed of by sale are reported at the lower of their carrying value or fair value less cost to sell and are not depreciated. Fair value is determined using the present value of estimated net cash flows or comparable market values. This approach uses significant estimates and assumptions including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates applied to determine terminal values, determination of appropriate market comparables and the determination of whether a premium or discount should be applied to comparables. Management believes that the estimates of future cash flows and fair values are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower future cash flows and fair values due to unforeseen changes in Sony’s businesses or assumptions could negatively affect the valuations of long-lived assets. Fair value measurement - Sony measures fair value as an exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Sony has elected the fair value option in the banking business for certain foreign securities. The election was made to mitigate accounting mismatches related to fluctuations of foreign exchange rates by allowing the gains and losses on the translation of these securities to be included in current earnings. Sony has also elected the fair value option for certain future insurance policy benefits and policyholders’ account in the life insurance business which are not normally measured at fair value. The election was made to mitigate accounting mismatches related to the changes in the fair value between liabilities for those future insurance policy benefits and policyholders’ account due to changes in the minimum guarantee risk of contracts of variable annuities with minimum guarantee benefits, and the underlying investment managed for policyholders and derivatives. Changes in fair value resulting from changes in instrument-specific credit risk were estimated by incorporating the certain subsidiary’s current credit spreads, and are recognized in other comprehensive income, net of tax. The accounting guidance for fair value measurements specifies a hierarchy of inputs to valuation techniques based on the extent to which inputs used in measuring fair value are observable in the market. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Sony’s assumptions about the assumptions that market participants would use in pricing the asset or liability. Observable market data is used if such data is available without undue cost and effort. Each fair value measurement is reported in one of three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:           Level 1   —   Inputs are unadjusted quoted prices for identical assets and liabilities in active markets.           Level 2   —   Inputs are based on observable inputs other than level 1 prices, such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.           Level 3   —   One or more significant inputs are unobservable.         When available, Sony uses unadjusted quoted market prices in active markets to measure fair value and classifies such items within level 1. If quoted market prices are not available, fair value is based upon internally developed valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates, currency rates and option volatilities. Items valued using internally generated models are classified according to the lowest level input that is significant to the valuation. For certain financial assets and liabilities, Sony determines fair value using third-party information such as indicative quotes from dealers and quantitative input from investment advisors following Sony’s established valuation procedures including validation against internally developed prices. Additionally, Sony considers both counterparty credit risk and Sony’s own creditworthiness in determining fair value. Sony attempts to mitigate credit risk to third parties by entering into netting agreements and actively monitoring the creditworthiness of counterparties and its exposure to credit risk through the use of credit limits and by selecting major international banks and financial institutions as counterparties. Transfers between levels are deemed to have occurred at the beginning of the interim period in which the transfers occur. Derivative financial instruments - All derivatives are recognized as either assets or liabilities in the consolidated balance sheets at fair value on a gross basis. Changes in the fair value of derivative financial instruments are either recognized periodically in income or stockholders’ equity (as a component of accumulated other comprehensive income), depending on whether the derivative financial instrument qualifies as a hedge and the derivative is being used to hedge changes in fair value or cash flows. The accounting guidance for hybrid financial instruments permits an entity to elect fair value remeasurement for any hybrid financial instrument if the hybrid instrument contains an embedded derivative that would otherwise be required to be bifurcated and accounted for separately under accounting guidance for derivative instruments and hedging activities. The election to measure the hybrid instrument at fair value is made on an instrument-by-instrument basis and is irreversible. Certain subsidiaries in the Financial Services segment had hybrid financial instruments, disclosed in Note 7 as debt securities, that contain embedded derivatives where the entire instrument was carried at fair value. In accordance with accounting guidance for derivative instruments and hedging activities, various derivative financial instruments held by Sony are classified and accounted for as described below. Fair value hedges Changes in the fair value of derivatives designated as fair value hedges for recognized assets or liabilities or unrecognized firm commitments are recognized in earnings as offsets to changes in the fair value of the related hedged assets or liabilities. Cash flow hedges Changes in the fair value of derivatives designated as cash flow hedges for forecasted transactions or exposures associated with recognized assets or liabilities are initially recorded in other comprehensive income and reclassified into earnings when the hedged transaction affects earnings. The time value component of the fair value of option contracts is excluded from the assessment of hedge effectiveness and recognized in earnings on a straight-line basis over the life of the hedging instruments. Any difference between the change in fair value of the excluded component and the accumulated amount recognized in earnings on a straight-line basis is recognized in other comprehensive income. Derivatives not designated as hedges Changes in the fair value of derivatives that are not designated as hedges are recognized immediately in earnings. Assessment of hedges When applying hedge accounting, Sony formally documents all hedging relationships between the derivatives designated as hedges and the hedged items, as well as its risk management objectives and strategies for undertaking various hedging activities. Sony links all hedges that are designated as fair value or cash flow hedges to specific assets or liabilities on the consolidated balance sheets or to the specific forecasted transactions. Sony also assesses, both at the inception of the hedge and on an on-going basis, whether the derivatives that are designated as hedges are highly effective in offsetting changes in fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge, Sony discontinues hedge accounting. Stock-based compensation - Sony accounts for stock-based compensation using the fair value - based method and the expense is mainly included in selling, general and administrative expenses. Sony accounts for its stock acquisition rights plan using the fair value measured on the date of grant using the Black-Scholes option-pricing model. The stock acquisition rights plan is recognized, net of an estimated forfeiture rate, over the requisite service period using the accelerated method of amortization for grants with graded vesting. The estimated forfeiture rate is based on Sony’s historical experience in the stock acquisition rights plans where the majority of the vesting terms have been satisfied. Revenue recognition - Sony recognizes revenue in an amount that reflects the consideration Sony expects in exchange for satisfying performance obligations to transfer the goods or services promised in contracts with customers. This is in accordance with the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) Sony satisfies a performance obligation. Sony owns a variety of intellectual property throughout segments and recognizes revenue through the licensing of such intellectual property. Sony has both functional and symbolic intellectual property. The licensing of functional intellectual property grants a customer a right to use Sony’s intellectual property as it exists at a point in time, and Sony satisfies its performance obligation at the point in time when the customer obtains control and is entitled to benefit from the license. The licensing of symbolic intellectual property grants a customer a right to access Sony’s intellectual property over time, and Sony satisfies its performance obligation over the license period as Sony maintains the intellectual property. Incremental costs of obtaining a contract and costs to fulfill a contract are recognized as assets when Sony expects to recover these costs. The incremental costs of obtaining a contract are those costs that would not have been incurred if the contract had not been obtained. Costs to fulfill a contract are those costs that are directly related to a contract or to an anticipated contract and that generate or enhance resources for Sony to satisfy its performance obligations. Sony applies a practical expedient and recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. Performance obligations in contracts for the EP&S and I&SS segments are primarily to deliver various kinds of electronic equipment, instruments and devices to customers. Revenues from these performance obligations are generally recognized when a promised good is delivered to a customer. However, if the sales contract contains a customer acceptance provision, then revenues are recognized when the customer accepts the promised good or when a deemed acceptance occurs by the lapse of time. Revenues are also recognized over time, primarily from the provision of internet broadband network services to subscribers over the subscription period. Revenues are recognized net of anticipated returns and sales incentives. Within the G&NS segment, revenues from hardware, peripherals and software discs are recognized when performance obligations are satisfied by transferring control to the retailer/distributor, net of anticipated returns, sales incentives and cooperative advertising obligations. Revenues from platform licensing to publishers are recognized when physical software discs are delivered. Revenues from digital game content, which is licensed functional intellectual property, are recognized when the digital content is made available for use by the licensee via an online platform, net of anticipated sales incentives and credit card chargebacks. Revenues from digital game content involving multiple performance obligations, such as obligations to make content available on future dates, are allocated to each performance obligation based on the relative standalone selling prices that are observable in the market or Sony’s best estimate. Revenues from subscription fees for digital subscription services are recognized over the subscription period. Within the Music segment, Sony licenses intellectual property that transfer to a customer either a right to use Sony’s intellectual property as it exists at the point in time in which the license is granted, or a right to access Sony’s intellectual property as it exists throughout the license period. Revenues are recognized when the customer has the right to use or access the intellectual property and obtains control of the use or access of that license. Digital revenues include revenues from contracts with digital streaming services typically recognized as a single performance obligation, which is ongoing access to intellectual property in an evolving library of content over the contract term, predicated on: (1) the business practice and contractual ability to remove specific content without a requirement to replace the content and without impact to minimum royalty guarantees and (2) the contracts not containing a specific listing of content subject to the license. For these contracts, revenues are recognized on the basis of sales and usage royalties, except where there is an amount of a minimum royalty guarantee that is not expected to be recouped, or a fixed fee, which is recognized on a straight-line basis over the term of the contract. Revenues from the sale of physical product such as CDs, net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public. Within the Pictures segment, revenues from the theatrical exhibition of motion pictures are recognized as the customer exhibits the film. Revenues from the licensing of motion picture and television programming for pay and free television exhibition and other markets are recognized when the product is available for use by the licensee. Revenues for motion picture and television program licensing arrangements involving multiple performance obligations, for example a fee for multiple titles, territories or availability dates, are allocated based on the relative standalone selling price of each performance obligation using Sony’s best estimate based on available information such as market conditions and internal pricing guidelines. Each individual motion picture or television programming product delivered generally represents a separate performance obligation. Licensing revenue associated with certain renewals or extensions of existing agreements for motion pictures and television programming is recognized when the licensee can use and benefit from the content under the renewal or extension. Licensing revenue associated with minimum guarantees for symbolic intellectual property is recognized ratably over the license term. For home entertainment distribution, revenues from the sale of physical product such as DVDs and Blu-ray Disc TM , net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public. Revenues from electronic sell-through and video-on-demand are recognized when the product is made available for viewing via digital distribution platforms. Revenues from the sale of broadcast advertising are recognized when the advertisement is aired, and the performance obligation in these arrangements is the delivery of advertising spots and may include a guaranteed amount of impressions. When a guarantee for a number of impressions is not achieved, revenues are not recognized until additional advertising spots are delivered to provide the guaranteed impressions. Revenues from subscription fees received by television networks are recognized when the service is provided. The performance obligation under network subscription arrangements is a license of functional intellectual property that is satisfied as programming is provided over the term of the arrangement. Traditional life insurance policies that the life insurance subsidiary underwrites, most of which are categorized as long-duration contracts, mainly consist of whole life, term life and accident and health insurance contracts. Premiums from these policies are reported as revenue when due from policyholders. Amounts received as payment for non-traditional contracts such as interest sensitive whole life contracts, individual annuity contracts and other contracts without life contingencies are recognized in policyholders’ account in the life insurance business. Revenues from these contracts are comprised of fees earned for administrative and contract-holder services, which are recognized over the period of the contracts, and included in financial services revenue. Property and casualty insurance policies that the non-life insurance subsidiary underwrites are primarily automotive insurance contracts which are categorized as short-duration contracts. Premiums from these policies are reported as revenue over the period of the contract in proportion to the amount of insurance protection provided. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities. Cost of sales - Costs classified as cost of sales relate to the producing and manufacturing of products and include items such as material cost, subcontractor cost, depreciation of fixed assets, amortization of intangible assets, personnel expenses, research and development costs, and amortization of film costs related to motion picture and television productions. Research and development costs - Research and development costs, included in cost of sales, include items such as salaries, personnel expenses and other direct and indirect expenses associated with research and product development. Research and development costs are expensed as incurred. Selling, general and administrative - Costs classified as selling expenses relate to promoting and selling products and include items such as advertising, promotion, shipping and warranty expenses. General and administrative expenses include operating items such as officers’ salaries, personnel expenses, depreciation of fixed assets, office rental for sales, marketing and administrative divisions, a provision for doubtful accounts and amortization of intangible assets. Financial services expenses - Financial services expenses include a provision for policy reserves and amortization of deferred insurance acquisition costs, and all other operating costs, such as personnel expenses, depreciation of fixed assets, and office rental of subsidiaries, in the Financial Services segment. Advertising costs - Advertising costs are expensed when the advertisement or commercial appears in the selected media. Shipping and handling costs - The majority of shipping and handling, warehousing and internal transfer costs for finished goods are included in selling, general and administrative expenses. An exception to this is in the Pictures segment where such costs are charged to cost of sales as they are an integral part of producing and distributing motion pictures and television programming. All other costs related to Sony’s distribution network are included in cost of sales, including inbound freight charges, purchasing and receiving costs, inspection costs and warehousing costs for raw materials and in-process inventory. Shipping and handling activities that occur after control of the related good transfers are treated as separate performance obligations. Amounts paid by customers for shipping and handling costs are included in net sales. Income taxes - The provision for income taxes is computed based on the pretax income included in the consolidated statements of income, and the tax liability attributed to undistributed earnings of subsidiaries and affiliated companies accounted for by the equity method expected to be remitted in the foreseeable future. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Carrying amounts of deferred tax assets require a reduction by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. Management’s judgments related to this assessment consider, among other matters, the nature, frequency and severity of current and cumulative losses on an individual tax jurisdiction basis, forecasts of future profitability after consideration of uncertain tax positions, excess of appreciated asset value over the tax basis of net assets, the duration of statutory carryforward periods, the past utilization of net operating loss carryforwards prior to expiration, as well as prudent and feasible tax planning strategies which would be employed by Sony to prevent net operating loss and tax credit carryforwards from expiring unutilized. Sony records assets and liabilities for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Sony continues to recognize interest and penalties, if any, with respect to income taxes, including unrecognized tax benefits, as interest expense and as income tax expense, respectively, in the consolidated statements of income. The amount of income taxes Sony pays is subject to ongoing audits by various taxing authorities, which may result in proposed assessments. In addition, several significant items related to intercompany transfer pricing are currently the subject of negotiations between taxing authorities in different jurisdictions as a result of pending advance pricing agreement applications and competent authority requests. Sony’s estimate for the potential outcome for any uncertain tax issues is judgmental and requires significant estimates. Sony assesses its income tax positions and records tax benefits for all years subject to examinations based upon the evaluation of the facts, circumstances and information available at that reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, Sony records the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. If Sony does not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. However, Sony’s future results may include favorable or unfavorable adjustments to Sony’s estimated tax liabilities due to closure of income tax examinations, the outcome of negotiations between taxing authorities in different jurisdictions, new regulatory or judicial pronouncements or other relevant events. As a result, the amount of unrecognized tax benefits, and the effective tax rate, may fluctuate significantly. The U.S. Tax Cuts and Jobs Act of 2017 (the “U.S. Tax Reform Act”) subjects a U.S. entity to tax on Global Intangible Low Tax Income (“GILTI”) earned by its foreign subsidiaries. Sony has elected to account for GILTI as a current period expense when incurred. Net income (loss) attributable to Sony Corporation’s stockholders per share (“EPS”) - Basic EPS is computed based on the weighted-average number of shares of common stock outstanding during each period. The computation of diluted EPS reflects the maximum possible dilution from conversion, exercise, or contingent issuance of securities. All potentially dilutive securities are excluded from the calculation in a situation where there is a net loss attributable to Sony Corporation’s stockholders. Leases - In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU  2016-02, which amends the accounting guidance for leases. The ASU requires substantially all leases to be recognized on the balance sheet. Sony has adopted this ASU effective April 1, 2019, on a modified retrospective basis with no restatement of comparative periods. Sony has elected the package of practical expedients for leases that expired or existed prior to the adoption date. As a result, Sony did not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases, or whether initial direct costs for any existing leases qualify for capitalization. In addition, Sony has applied the short-term lease exception. As a result of the adoption of this ASU, Sony recognized 316,923 million yen of operating lease right-of-use assets and 341,251 million yen of lease liabilities for operating leases on the consolidated balance sheets at April 1, 2019. This impact is mainly due to operating leases of real estate. The difference of 24,328 million yen between right-of-use assets and lease liabilities represents deferred rent for leases that existed as of the date of adoption, which was offset against the opening balance of operating lease right-of-use assets. Finance lease   right-of-use assets which are included in property, plant and equipment in the consolidated balance sheets for the fiscal year ended March 31, 2019, are now presented as finance lease right-of-use assets from April 1, 2019 onward. Premium amortization on purchased callable debt securities - In March 2017, the FASB issued ASU 2017-08, which requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be affected. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position. Targeted improvements to accounting for hedging activities - In August 2017, the FASB issued ASU 2017-12, which made targeted improvements to the accounting for hedging activities. The amendments in this update simplify certain aspects of hedge accounting for both non-financial and financial risks and better align the recognition and measurement of hedge results with an entity’s risk management activities. This ASU also amends certain presentation and disclosure requirements for hedging activities and changes how an entity assesses hedge effectiveness. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position. (3) Recent accounting pronouncements not yet adopted                         Measurement of credit losses on financial instruments - In June 2016, the FASB issued ASU 2016-13, which amends the accounting guidance for credit losses on financial instruments. The ASU requires the consideration of all available relevant information when estimating expected credit losses, including past events, current conditions and forecasts and their implications for expected credit losses. This ASU is effective for Sony as of April 1, 2020. The adoption of this ASU is not expected to have a material impact on Sony’s results of operations and financial position. Improvements to Accounting for Costs of Films and License Agreements for Program Materials - In March 2019, the FASB issued ASU 2019-02, which updates the guidance for the capitalization of film costs associated with episodic television series, requires the use of fair value rather than net realizable value when determining potential impairments of broadcasting rights, and modifies the presentation and disclosure requirements for films and broadcasting rights. In addition, upon capitalization of film costs entities are required to determine qualitatively whether the predominant monetization strategy is on a title-by-title basis or together with other films and/or broadcast rights as part of a film group, such as in the case of a release of a film as part of a library of content on a streaming service. In the case of a film group, impairments are evaluated at the overall film group level rather than the individual title level. This ASU is effective for Sony as of April 1, 2020 and is applied on a prospective basis. Upon adoption, Sony will reclassify  approximately 24.1 b illion yen of broadcasting rights in the Pictures segment and  ap proximately  7.4   b illion yen of animation film production costs in the Music segment included in inventor ies  to film costs. Targeted Improvements to the Accounting for Long-Duration Contracts - In August 2018, the FASB issued ASU 2018-12, which revises the accounting for certain long-duration insurance contracts, and in November 2019, the FASB issued ASU 2019-09 to defer the effective date of ASU 2018-12 to January 1, 2022. The ASU prescribes comprehensive changes to recognition and measurement of certain long-duration insurance contracts and assumptions and introduces certain financial statement presentation requirements, as well as significant additional qualitative and quantitative disclosures. This ASU will be effective for Sony as of April 1, 2022. The impact of this ASU on Sony’s results of operations and financial position is being evaluated. Disclosures for Fair Value Measurement - In August 2018, the FASB issued ASU 2018-13, which amends disclosure requirements related to fair value measurement. This ASU is effective for Sony as of April 1, 2020. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position. Disclosures for Defined Benefit Plans - In August 2018, the FASB issued ASU 2018-14, which amends disclosure requirements related to defined benefit pension and other postretirement plans. This ASU is effective for Sony as of April 1, 2020 and will be applied on a retrospective basis. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position. Income Taxes - In December 2019, the FASB issued ASU 2019-12, which simplifies the accounting requirements for income taxes. This ASU will be effective for Sony as of April 1, 2021 and amendments within this ASU are required to be applied on a prospective basis, except certain amendments must be applied on a retrospective or modified retrospective basis. The impact of this ASU on Sony’s results of operations and financial position is being evaluated. Reference Rate Reform - In March 2020, the FASB issued ASU 2020-04, which provides optional relief for certain contracts impacted by reference rate reform. The relief provided by the amendments is permitted to be adopted any time through December 31, 2022. Sony is still evaluating the impact of reference rate reform and whether to apply the optional relief. (4) Reclassifications                       Certain reclassifications of the financial statements and accompanying footnotes for the fiscal years ended March 31, 2018 and 2019 have been made to conform to the presentation for the fiscal year ended March 31, 2020.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of the Carrying Value of the Variable Interests	The following tables present the carrying value of the variable interests of unconsolidated VIEs, the presentation in the consolidated balance sheet, and the maximum exposure to loss associated with these variable interests as of March 31, 2019 and 2020. Maximum exposure to loss does not reflect Sony’s estimate of the actual losses that could result from adverse changes, nor does it reflect the economic hedges Sony enters into to reduce its exposure. The risks associated with VIEs in which Sony is involved are limited to the amount recorded in the consolidated balance sheets and the amount of commitments.                                     Yen in millions     March 31, 2019     Presentation in the consolidated balance sheets     Maximum exposure to loss     Marketable securities     Securities investments and other     Prepaid expenses and other current assets   Equity securities *1     135,552       8,485       —       146,031   Securitized products     —       191,049       —       195,190   Foreign corporate bonds *2     29,889       65,503       —       95,392   Other investments     —       4,688       21,000       25,688                                     Total     165,441       269,725       21,000       462,301                                                                                   Yen in millions     March 31, 2020     Presentation in the consolidated balance sheets     Maximum exposure to loss     Marketable securities     Securities investments and other     Prepaid expenses and other current assets   Equity securities *1     579,773       6,229       —       587,602   Securitized products     —       210,641       —       210,641   Foreign corporate bonds *2     41,452       41,036       —       82,488   Other investments     —       16,253       21,000       43,719                                     Total     621,225       274,159       21,000       924,450                                               *1 Equity securities include Investment funds.           *2 Foreign corporate bonds include repackaged bonds.

Kumamoto Earthquake	12 Months Ended
	Mar. 31, 2020
Unusual or Infrequent Items, or Both [Abstract]
Kumamoto Earthquake	18. Kumamoto Earthquake             In April 2016, a series of earthquakes occurred in the Kumamoto region of Japan. These earthquakes caused damage to certain fixed assets, including buildings, machinery and equipment, as well as inventories in manufacturing sites located in the Kumamoto region. For the fiscal year ended March 31, 2017, Sony incurred incremental losses and associated expenses including repair costs of fixed assets and a loss on disposal of inventories directly related to the damage caused by the earthquakes of 16,682 million yen. These losses and expenses were primarily recorded in cost of sales in the consolidated statements of income and were offset by insurance recoveries of 10,682 million yen, as described below. In addition, Sony incurred other expenses of 9,365 million yen, which included idle facility costs at manufacturing sites. These expenses were primarily recorded in cost of sales in the consolidated statements of income. Sony has insurance policies that cover certain damage directly caused by the earthquakes for Sony Corporation and certain of its subsidiaries, including damage at manufacturing sites. The insurance policies cover the damage and costs associated with fixed assets and inventories, as well as incremental expenses including removal and cleaning costs. These policies also provide business interruption coverage, including coverage for lost profits. For the fiscal year ended March 31, 2017, Sony recorded insurance receivables of 10,682 million yen, representing a portion of the insurance recoveries that were deemed probable of collection up to the extent of the amount of corresponding losses recognized in the same period. Of the insurance receivables recorded during the period, substantially all relate to damaged assets and inventories, and do not include amounts for business interruption or lost profits. Sony concluded that the recoveries from insurance claims are probable based on the coverage under valid policies, communications with the insurance carriers, Sony’s past claims history with the insurance carriers, and Sony’s assessment that the insurance carriers have the financial ability to pay the claims. In March 2017, 10,000 million yen was agreed to by the insurance carriers. These receivables are recorded within other receivables, whereas the remaining receivables of 682 million yen is recorded in other current assets in the consolidated balance sheets as of the fiscal year ended March 31, 2017. Sony has underwritten 2,000 million yen in reinsurance policies for the above insurance carriers related to the policy described above. The amount was recorded in other current liabilities in the consolidated balance sheets as of the fiscal year ended March 31, 2017 and was paid to the insurance carriers in the fiscal year ended March 31, 2018. In April 2017, the remaining insurance claims of 10,000 million yen that were mainly for business interruption coverage were agreed to by the carriers. As a result, the total amount of insurance recoveries paid to Sony in April 2017 was 20,000 million yen. 9,318 million yen, which was the difference between 20,000 million yen and 10,682 million yen as described above, was recorded in other operating revenue for the fiscal year ended March 31, 2018. The proceeds from insurance recoveries were presented as cash flows from operating activities in the consolidated statements of cash flows for the fiscal year ended March 31, 2018.

Derivative instruments and hedging activities	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative instruments and hedging activities	14. Derivative instruments and hedging activities         Sony has certain financial instruments including financial assets and liabilities acquired in the normal course of business. Such financial instruments are exposed to market risk arising from the changes in foreign currency exchange rates and interest rates. In applying a consistent risk management strategy for the purpose of reducing such risk, Sony uses derivative financial instruments, which include foreign exchange forward contracts, foreign currency option contracts, and interest rate swap agreements (including interest rate and currency swap agreements). Certain other derivative financial instruments are entered into in the Financial Services segment for asset-liability management (“ALM”) purposes. These instruments are executed with creditworthy financial institutions, and virtually all foreign currency contracts are denominated in U.S. dollars, euros and other currencies of major countries. These derivatives generally mature or expire within six months after the balance sheet date. Other than derivatives utilized in the Financial Services segment for ALM, Sony does not use derivative financial instruments for trading or speculative purposes. These derivative transactions utilized for ALM in the Financial Services segment are executed within certain limits in accordance with an internal risk management policy. Derivative financial instruments held by Sony are classified and accounted for as described below. Fair value hedges Both the derivatives designated as fair value hedges and the hedged items are reflected at fair value in the consolidated balance sheets. Changes in the fair value of the derivatives designated as fair value hedges, as well as offsetting changes in the carrying value of the underlying hedged items, are recognized in income. For the fiscal years ended March 31, 2018 , 2 019 and 20 20 , there were no amounts excluded from the assessment of hedge effectiveness of fair value hedges. Cash flow hedges Changes in the fair value of derivatives designated as cash flow hedges are initially recorded in other comprehensive income (“OCI”) and reclassified into earnings when the hedged transaction affects earnings. The time value component of the fair value of option contracts is excluded from the assessment of hedge effectiveness and recognized in earnings on a straight-line basis over the life of the hedging instruments. Any difference between the change in fair value of the excluded component and the accumulated amount recognized in earnings on a straight-line basis   is recognized in OCI. Derivatives not designated as hedges Changes in the fair value of derivatives not designated as hedges are recognized in income. A description of the purpose and classification of the derivative financial instruments held by Sony is as follows: Foreign exchange forward contracts and foreign currency option contracts Foreign exchange forward contracts and purchased and written foreign currency option contracts are utilized primarily to limit the exposure affected by changes in foreign currency exchange rates on cash flows generated or anticipated by Sony’s transactions and accounts receivable and payable denominated in foreign currencies. The majority of written foreign currency option contracts are a part of range forward contract arrangements and expire in the same month with the corresponding purchased foreign currency option contracts. Sony also entered into foreign exchange forward contracts and foreign exchange range forward contracts which effectively fixed the cash flows from certain forecasted purchase and sale transactions denominated in foreign currencies for the fiscal years ended March 31,   2018 , 2019 and 20 20 . Accordingly, these derivatives have been designated as cash flow hedges. Foreign exchange forward contracts and foreign currency option contracts that do not qualify as hedges are marked-to-market with changes in value recognized in other income and expenses. Foreign exchange forward contracts, foreign currency option contracts and currency swap agreements held by certain subsidiaries in the Financial Services segment are marked-to-market with changes in value recognized in financial services revenue. Interest rate swap agreements (including interest rate and currency swap agreements) Interest rate swap agreements are utilized primarily to lower funding costs, to diversify sources of funding and to limit Sony’s exposure associated with underlying borrowings and available-for-sale debt securities resulting from adverse fluctuations in interest rates, foreign currency exchange rates and changes in fair values. Interest rate swap agreements entered into in the Financial Services segment are used for reducing the risk arising from the changes in the fair value of fixed rate available-for-sale debt securities. These derivatives are considered to be a hedge against changes in the fair value of available-for-sale debt securities in the Financial Services segment. Accordingly, these derivatives have been designated as fair value hedges. Certain subsidiaries in the Financial Services segment have interest rate swap agreements as part of their ALM, which are marked-to-market with changes in value recognized in financial service revenues. Any other interest rate swap agreements that do not qualify as hedges, which are used for reducing the risk arising from changes of variable rate debt, are marked-to-market with changes in value recognized in other income and expenses. Other agreements Certain subsidiaries in the Financial Services segment have equity future contracts, equity swap agreements, bond future contracts, commodity future contracts, interest rate swaption agreements, other currency contracts and hybrid financial instruments as part of their ALM, which are marked-to-market with changes in value recognized in financial services revenue. The hybrid financial instruments, disclosed in Note 7 as debt securities, contained embedded derivatives that are not required to be bifurcated because the entire instruments are carried at fair value. The estimated fair values of Sony’s outstanding derivative instruments are summarized as follows:                                           Derivatives designated as hedging instruments   Yen in

Revenue             (1) Contract balances Receivables from contracts with customers, contract assets and contract liabilities are comprised of the following:                     Yen in millions     March   3 1, 2019     March 31, 2020   Receivables from contracts with customers *1     1,183,115       1,126,597   Contract assets *1     19,147       13,985   Contract liabilities *2     254,646       271,286                 *1 Receivables from contracts with customers and contract assets are included in the consolidated balance sheets as “Notes and accounts receivable, trade and contract assets” and “Other”, non-current.               *2 Contract liabilities are included in the consolidated balance sheets as “Other”, both current and non-current.             Contract liabilities principally relate to customer advances received prior to performance. Revenues of 204,265 million yen were recognized during the fiscal year ended March 31, 2020, which were included in the balance of contract liabilities at March 31 , 2019. Revenues of 61,706 million yen were recognized during the fiscal year ended March 31, 2020 from performance obligations satisfied prior to March 31, 2019. (2) Performance obligations             Remaining (unsatisfied or partially unsatisfied) performance obligations represent future revenues not yet recorded for firm orders that have not yet been performed. Sony applies practical expedients to exclude certain information about the remaining performance obligations, primarily related to contracts with an expected original duration of less than one year, and sales-based or usage-based royalty revenue on licenses of intellectual property. The following table shows the summary of the transaction prices allocated to remaining performance obligations that are unsatisfied at March 31, 2020, of which more than half are expected to be recognized within one year and substantially all within three years.             Yen in millions     March 31, 2020   Pictures — Motion Pictures and Television Productions *1     569,081   Pictures — Media Networks     22,333   Music *2     44,971   Others     47,126                 *1 For Motion Pictures and Television Productions in the Pictures segment, Sony has included all contracts regardless of duration.               *2 Amount included in the Music segment primarily consists of minimum royalty guarantees or fixed fees in contracts related to license revenue for ongoing access to an evolving library of content. These contracts also include the potential for sales-based or usage-based royalties to exceed the minimum guarantees, and these additional royalties are excluded from the amount above, of which substantially all are recognized as revenue within three years.             (3) Contract costs Contract costs are comprised as follows:                     Yen in millions     March 31 , 2019     March 31, 2020   Incremental costs of obtaining a contract     6,581       7,464               Sony applies practical expedients to recognize the incremental costs of obtaining a contract as an expense if the amortization period of the asset that otherwise would have been recognized is one year or less. The amortization of 6,420 million yen was recognized during the fiscal year ended March 31, 2020. The incremental costs of obtaining a contract are primarily recognized in the EP&S segment for the internet-related service business and amortized to expense over the contract period. (4) Disaggregation of revenue             For the breakdown of sales and operating revenue by segments, product categories and geographies, refer to Note 29.

Pension and severance plans	12 Months Ended

Retirement Benefits [Abstract]
Pension and severance plans	15. Pension and severance plans         (1) Defined benefit and severance plans         Upon terminating employment, employees of Sony Corporation and its subsidiaries in Japan are entitled, under most circumstances, to lump-sum indemnities or pension payments as described below. Sony Corporation and certain of its subsidiaries’ pension plans utilize a point-based plan under which a point is added every year reflecting the individual employee’s performance over that year. Under the point-based plan, the amount of payment is determined based on the sum of cumulative points from past services and interest points earned on the cumulative points regardless of whether or not the employee is voluntarily retiring. Under the plans, in general, the defined benefits cover 65% of the indemnities under existing regulations to employees. The remaining indemnities are covered by severance payments by the companies. The pension benefits are payable at the option of the retiring employee either in a lump-sum amount or monthly pension payments. Contributions to the plans are funded through several financial institutions in accordance with the applicable laws and regulations. From April 1, 2012, Sony Corporation and substantially all of its subsidiaries in Japan have modified existing defined benefit pension plans such that life annuities will no longer accrue additional service benefits, with those participants instead accruing fixed-term annuities. The defined benefit pension plans were closed to new participants and a defined contribution plan was also introduced. From October 1, 2019, Sony Corporation and substantially all of its subsidiaries in Japan have amended their defined benefit pension plans and have implemented defined contribution plans for all employees other than those employees that had retired before the amendments. As a result, accrued pension and severance costs decreased 74,872 million yen and accumulated other comprehensive income increased 81,230 million yen in the consolidated balance sheets as of the fiscal year ended March 31, 2020. In addition, a loss on the pension plan amendment of 6,358 million yen was recorded in other expenses in the consolidated statements of income for the fiscal year ended March 31, 2020. In addition, several of Sony’s foreign subsidiaries have defined benefit pension plans or severance indemnity plans, which cover substantially all of their employees. Under such plans, the related cost of benefits is currently funded or accrued. Benefits awarded under these plans are based primarily on the current rate of pay and length of service. The components of net periodic benefit costs for the fiscal years ended March 31, 2018, 2019 and 2020 were as follows: Japanese plans :                             Yen in millions     Fiscal year ended March 31     2018     2019     2020   Service cost     25,185       23,128       17,948   Interest cost     8,024       7,020       4,162   Expected return on plan assets     (16,440 )     (16,695 )     (17,040 ) Recognized actuarial loss     16,099       15,365       12,969   Amortization of prior service costs     (8,693 )     (7,864 )     (4,294 ) Losses on curtailments and settlements     —       —       6,358                             Net periodic benefit costs     24,175       20,954       20,103                                         Foreign plans :                             Yen in millions     Fiscal year ended March 31     2018     2019     2020   Service cost     3,181       2,780       3,616   Interest cost     10,393       10,083       9,212   Expected return on plan assets     (11,687 )     (11,797 )     (10,916 ) Amortization of net transition asset     5       —       —   Recognized actuarial loss     3,014       2,656       2,606   Amortization of prior service costs     (574 )     (269 )     2   Losses on curtailments and settlements     1,058       1,804       68                             Net periodic benefit costs     5,390       5,257       4,588                                         The components of net periodic benefit costs other than service cost for the fiscal year s ended March 31, 2019 and 2020 are included within other expenses (income) in the consolidated statements of income. The estimated net actuarial loss and prior service cost for the defined benefit pension plans that will be amortized from accumulated other comprehensive income into net periodic benefit costs over the next fiscal year are 12,185 million yen and 1,412 million yen, respectively. The changes in the benefit obligation and plan assets as well as the funded status and composition of amounts recognized in the consolidated balance sheets were as follows:                                     Japanese plans     Foreign plans     Yen in millions     Yen in millions     March 31     March 31     2019     2020     2019     2020   Change in benefit obligation:                         Benefit obligation at beginning of the fiscal year     1,010,574       1,034,954       356,397       351,918   Service cost     23,128       17,948       2,780       3,616   Interest cost     7,020       4,162       10,083       9,212   Plan participants’ contributions     —       —       462       487   Plan amendments       —       —       —       10,210   Actuarial (gain) loss     29,295       (3,330 )     1,700       19,776   Foreign currency exchange rate changes     —       —       (1,554 )     (16,919 ) Curtailments and settlements     —       (359,205 )     (6,120 )     (4,434 ) Effect of changes in consolidated subsidiaries     —       —       1,947       —   Other     6       2       —       —   Benefits paid     (35,069 )     (35,668 )     (13,777 )     (14,055 )                                   Benefit obligation at end of the fiscal year     1,034,954       658,863       351,918       359,811                                     Change in plan assets:                         Fair value of plan assets at beginning of the fiscal year     711,077       742,204       269,745       274,749   Actual return on plan assets     18,701       2,942       15,243       26,738   Foreign currency exchange rate changes     —       —       (838 )     (14,904 ) Employer contribution     36,875       7,453       8,542       9,916   Plan participants’ contributions     —       —       462       487   Curtailments and settlements     —       (284,333 )     (5,960 )     (3,146 ) Benefits paid     (24,449 )     (31,060 )     (12,445 )     (12,730 )                                   Fair value of plan assets at end of the fiscal year     742,204       437,206       274,749       281,110                                     Funded status at end of the fiscal year     (292,750 )     (221,657 )     (77,169 )     (78,701 )                                               Amounts recognized in the consolidated balance sheets consist of:                                     Japanese plans     Foreign plans     Yen in millions     Yen in millions     March 31     March 31     2019     2020     2019     2020   Noncurrent assets     3,476       3,391       14,745       24,777   Current liabilities     —       —       (4,412 )     (4,355 ) Noncurrent liabilities     (296,226 )     (225,048 )     (87,502 )     (99,123 )                                   Ending balance     (292,750 )     (221,657 )     (77,169 )     (78,701 )                                               Amounts recognized in accumulated other comprehensive income, excluding tax effects, consist of:                                     Japanese plans     Foreign plans     Yen in millions     Yen in millions     March 31     March 31     2019     2020     2019     2020   Prior service cost (credit)     (8,859 )     (369 )     (45 )     10,058   Net actuarial loss     311,128       223,354       71,906       66,326                                     Ending balance     302,269       222,985       71,861       76,384                                                 The accumulated benefit obligations for all defined benefit pension plans were as follows:                                     Japanese plans     Foreign plans     Yen in millions     Yen in millions     March 31     March 31     2019     2020     2019     2020   Accumulated benefit obligations     1,029,910       654,209       336,185       354,100         The projected benefit obligations, the accumulated benefit obligations and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were as follows:                                     Japanese plans     Foreign plans     Yen in millions     Yen in millions     March 31     March 31     2019     2020     2019     2020   Projected benefit obligations     1,022,235       645,544       200,596       230,058   Accumulated benefit obligations     1,017,191       640,890       196,928       226,080   Fair value of plan assets     726,009       420,497       123,937       130,955         Weighted-average assumptions used to determine benefit obligations as of March 31, 2019 and 2020 were as follows:                                     Japanese plans     Foreign plans     March 31     March 31     2019     2020     2019     2020   Discount rate     0.6 %     0.6 %     2.8 %     2.0 % Rate of compensation increase     *       *       2.3       2.2           * Substantially all of Sony’s Japanese pension plans were point-based. Point-based plans do not incorporate a measure of compensation rate increases.       Weighted-average assumptions used to determine the net periodic benefit costs for the fiscal years ended March 31, 2018, 2019 and 2020 were as follows:                                                     Japanese plans     Foreign plans     Fiscal year ended March 31     Fiscal year ended March 31     2018     2019     2020     2018     2019     2020   Discount rate     0.9 %     0.8 %     0.6 %     3.1 %     2.9 %     2.8 % Expected return on plan assets     2.4       2.6       2.6       4.6       4.4       4.2   Rate of compensation increase     *       *       *       2.4       2.6       2.3         * Substantially all of Sony’s Japanese pension plans were point-based. Point-based plans do not incorporate a measure of compensation rate increases. Sony reviews these assumptions for changes in circumstances. The weighted-average rate of compensation increase is calculated based only on the pay-related plans. The point-based plans discussed above are excluded from the calculation because payments made under the plan are not based on employee compensation. The mortality rate assumptions are based on life expectancy and death rates for different types of participants. To determine the expected long-term rate of return on pension plan assets, Sony considers the current and expected asset allocations, as well as the historical and expected long-term rates of returns on various categories of plan assets. Sony’s pension investment policy recognizes the expected growth and the variability risk associated with the long-term nature of pension liabilities, the returns and risks of diversification across asset classes, and the correlation among assets. The asset allocations are designed to maximize returns consistent with levels of liquidity and investment risk that are considered prudent and reasonable. While the pension investment policy gives appropriate consideration to recent market performance and historical returns, the investment assumptions utilized by Sony are designed to achieve a long-term return consistent with the long-term nature of the corresponding pension liabilities. The investment objectives of Sony’s plan assets are designed to generate returns that will enable the plans to meet their future obligations. The precise amount for which these obligations will be settled depends on future events, including the retirement dates and life expectancy of the plans’ participants. The obligations are estimated using actuarial assumptions, based on the current economic environment and other pertinent factors. Sony’s investment strategy balances the requirement to generate returns, using potentially higher yielding assets such as equity securities, with the need to control risk in the portfolio with less volatile assets, such as fixed-income securities. Risks include, among others, inflation, volatility in equity values and changes in interest rates that could negatively impact the funding level of the plans, thereby increasing its dependence on contributions from Sony. To mitigate any potential concentration risk, thorough consideration is given to balancing the portfolio among industry sectors and geographies, taking into account interest rate sensitivity, dependence on economic growth, currency and other factors that affect investment returns. The target allocations as of March 31, 2020, are, as a result of Sony’s asset liability management, 17% of equity securities, 54% of fixed income securities and 29% of other investments for the pension plans of Sony Corporation and most of its subsidiaries in Japan, and, on a weighted average basis, 14% of equity securities, 63% of fixed income securities and 23% of other investments for the pension plans of foreign subsidiaries. The fair values of the assets held by Japanese and foreign plans, which are classified in accordance with the fair value hierarchy described in Note 2, are as follows:                                     Japanese plans     Yen in millions     Fair value at March 31, 2019     Fair value measurements using inputs considered as   Asset class Level 1     Level 2     Level 3   Cash and cash equivalents     10,689       10,689       —       —   Equity:                         Equity securities *1     140,559       135,713       4,846       —   Fixed income:                         Government bonds *2     210,817       —       210,817       —   Corporate bonds *3     97,519       —       97,519       —   Asset-backed securities *4     1,537       —       1,537       —   Commingled funds *5     138,455       —       138,455       —   Commodity funds *6     21,674       —       21,674       —   Private equity *7     27,956       —       —       27,956   Hedge funds *8     71,606       —       —       71,606   Real estate and other *9     21,392       —       —       21,392                                     Total     742,204       146,402       474,848       120,954                                                                               Japanese plans     Yen in millions     Fair value at March 31, 2020     Fair value measurements using inputs considered as   Asset class Level 1     Level 2     Level 3   Cash and cash equivalents     24,851       24,851       —       —   Equity:                         Equity securities *1     50,646       47,308       3,338       —   Fixed income:                         Government bonds *2     107,478       1,087       106,391       —   Corporate bonds *3     71,192       20       71,172       —   Asset-backed securities *4     1,090       —       1,090       —   Commingled funds *5     58,740       —       58,740       —   Commodity funds *6     21,823       —       21,823       —   Private equity *7     30,191       —       —       30,191   Hedge funds *8     48,410       —       —       48,410   Real estate and other *9     22,785       —       (2,586 )     25,371                                     Total     437,206       73,266       259,968       103,972                                                     *1 Includes approximately 51 percent and 37 percent of Japanese equity securities, and 49 percent and 63 percent of foreign equity securities for the fiscal years ended March 31, 2019 and 2020, respectively.                 *2 Includes approximately 48 percent and 36 percent of debt securities issued by Japanese national and local governments, and 52 percent and 64 percent of debt securities issued by foreign national and local governments for the fiscal years ended March 31, 2019 and 2020, respectively.                 *3 Includes debt securities issued by Japanese and foreign corporation and government related agencies.                 *4 Includes primarily mortgage-backed securities.                 *5 Commingled funds represent pooled institutional investments, including primarily investment trusts.

The following is a description of the valuation techniques used to measure Japanese and foreign plan assets at fair value. The valuation techniques are applied consistently from period to period. Equity securities are valued at the closing price reported in the active market in which the individual securities are traded. These assets are generally classified as level 1. The fair value of fixed income securities is typically estimated using pricing models, quoted prices of securities with similar characteristics or discounted cash flows and are generally classified as level 2. Commingled funds are typically measured using the valuation provided by the administrator of the fund and reviewed by Sony. The valuation is based on Sony’s interest in the value of the underlying assets owned by the fund minus liabilities. These assets are classified as level 1, level 2 or level 3 depending on availability of quoted market prices. Commodity funds are valued using inputs that are derived principally from or corroborated by observable market data. These assets are generally classified as level 2. Private equity and private real estate investment trust valuations require significant judgment due to the absence of quoted market prices, the inherent lack of liquidity and the long-term nature of such assets. These assets are initially valued at cost and are reviewed periodically utilizing available and relevant market data to determine if the carrying value of these assets should be adjusted. These investments are classified as level 3. Hedge funds are measured using the valuation provided by the administrator or custodian of the fund and reviewed by Sony. The valuation is based on Sony’s interest in the value of the underlying assets owned by the fund minus liabilities. These investments are classified as level 3. The following table sets forth a summary of changes in the fair values of Japanese and foreign plans’ level 3 assets for the fiscal years ended March 31, 2019 and 2020:                                     Japanese plans     Yen in millions     Fair value measurement using significant unobservable inputs (Level 3)     Private equity     Hedge funds     Real estate and other     Total   Beginning balance at April 1, 2018     24,144       70,204       19,431       113,779   Return on assets held at end of year     4,428       659       1,622       6,709   Purchases, sales, and settlements, net     (616 )     743       339       466                                     Ending balance at March 31, 2019     27,956       71,606       21,392       120,954                                     Return on assets held at end of year     2,649       (648 )     418       2,419   Purchases, sales, and settlements, net     (414 )     (22,548 )     3,561       (19,401 )                                   Ending balance at March 31, 2020     30,191       48,410       25,371       103,972                                               Foreign plans     Yen in millions     Fair value measurement using significant unobservable inputs (Level 3)     Insurance contracts     Corporate bonds     Real estate and other     Total   Beginning balance at April 1, 2018     12,729       5,303       25,976       44,008   Return on assets held at end of year     736       —       559       1,295   Purchases, sales, and settlements, net     (389 )     —       (3,809 )     (4,198 ) Transfers, net     —       (5,540 )     123       (5,417 ) Other *     (582 )     237       (760 )     (1,105 )                                   Ending balance at March 31, 2019     12,494       —       22,089       34,583                                     Return on assets held at end of year     559       —       132       691   Purchases, sales, and settlements, net     (373 )     —       755       382   Transfers, net     —       —       —       —   Other *     (502 )     —       (679 )     (1,181 )                                   Ending balance at March 31, 2020     12,178       —       22,297       34,475                                             * Primarily consists of translation adjustments.       Sony makes contributions to its defined benefit pension plans as deemed appropriate by management after considering the fair value of plan assets, expected return on plan assets and the present value of benefit obligations.

Variable interest entities	12 Months Ended
	Mar. 31, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable interest entities	24. Variable interest entities       Sony has entered into various arrangements with VIEs. (1 ) Consolidated VIEs       Sony’s U.S. subsidiary that is engaged in the recorded music business has entered into several joint ventures with companies involved in the production and creation of recorded music. Sony has reviewed these joint ventures and determined that they are VIEs. Based on a qualitative assessment, it was determined that Sony has the power to direct the activities that most significantly impact the VIEs’ economic performance, as well as the obligation to absorb the losses of these VIEs as Sony is responsible for providing funding to these VIEs, and in most cases absorbs all losses until the VIEs become profitable. As a result, it has been determined that Sony is the primary beneficiary and, accordingly, these VIEs are consolidated by Sony. The assets of Sony are not available to settle the obligations of these VIEs. As of March 31, 2020, the total assets and liabilities for these VIEs, on an aggregate basis, were 46,154 million yen and 25,100 million yen, respectively. (2) Unconsolidated VIEs             As described in Note 6, certain accounts receivable sales programs also involve VIEs. These VIEs are all special purpose entities associated with the sponsor banks. Based on a qualitative assessment, Sony is not the primary beneficiary and therefore does not consolidate these entities as Sony does not have the power to direct the activities, an obligation to absorb losses, or the right to receive the residual returns of these VIEs. Sony’s maximum exposure to losses from these VIEs is considered insignificant. In the Financial Services segment, Sony has variable interests in VIEs where Sony is not the primary beneficiary. Sony’s variable interests in such VIEs include equity securities, securitized products, foreign corporate bonds and other investments. The following tables present the carrying value of the variable interests of unconsolidated VIEs, the presentation in the consolidated balance sheet, and the maximum exposure to loss associated with these variable interests as of March 31, 2019 and 2020. Maximum exposure to loss does not reflect Sony’s estimate of the actual losses that could result from adverse changes, nor does it reflect the economic hedges Sony enters into to reduce its exposure. The risks associated with VIEs in which Sony is involved are limited to the amount recorded in the consolidated balance sheets and the amount of commitments.                                     Yen in millions     March 31, 2019     Presentation in the consolidated balance sheets     Maximum exposure to loss     Marketable securities     Securities investments and other     Prepaid expenses and other current assets   Equity securities *1     135,552       8,485       —       146,031   Securitized products     —       191,049       —       195,190   Foreign corporate bonds *2     29,889       65,503       —       95,392   Other investments     —       4,688       21,000       25,688                                     Total     165,441       269,725       21,000       462,301                                                                                   Yen in millions     March 31, 2020     Presentation in the consolidated balance sheets     Maximum exposure to loss     Marketable securities     Securities investments and other     Prepaid expenses and other current assets   Equity securities *1     579,773       6,229       —       587,602   Securitized products     —       210,641       —       210,641   Foreign corporate bonds *2     41,452       41,036       —       82,488   Other investments     —       16,253       21,000       43,719                                     Total     621,225       274,159       21,000       924,450                                               *1 Equity securities include Investment funds.           *2 Foreign corporate bonds include repackaged bonds.

(2) Purchase commitments and other       Purchase commitments and other outstanding as of March 31, 2020 amounted to 684,911 million yen. The major components of these commitments are as follows: Certain subsidiaries in the Pictures segment have entered into agreements with creative talent for the development and production of motion pictures and television programming as well as agreements with third parties to acquire completed motion pictures, or certain rights therein, and to acquire the rights to broadcast certain live action sporting events.

The schedule of the aggregate amounts of year-by-year payment of purchase commitments during the next five fiscal years and thereafter is as follows:           Fiscal year ending March 31   Yen in millions   2021     378,319   2022     103,033   2023     76,541   2024     49,549   2025     36,936   Later fiscal years     40,533             Total     684,911                 (3) Litigation       Beginning in 2009, the U.S. Department of Justice (“DOJ”), the European Commission and certain other governmental agencies outside the United States have conducted investigations relating to competition in the optical disk drives market. Sony Corporation and/or certain of its subsidiaries have been subject to these investigations. Sony Corporation understands that these investigations have ended. However, proceedings initiated by the European Commission as a result of its investigation continue. In October 2015, the European Commission adopted a decision in which it fined Sony Corporation and certain of its subsidiaries 31 million euros; however, Sony Corporation filed an appeal against the decision with the European Union’s General Court. In July 2019, the General Court upheld the European Commission’s decision. Sony  Corporation reviewed the judgment carefully and filed an appeal with the Court of Justice of the European Union in September 2019. A number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceedings will not have a material impact on Sony’s results of operations and financial position. Since 2011, in relation to the secondary batteries business that was operated by Sony Corporation and certain of its subsidiaries, a number of direct and indirect purchaser lawsuits, including class actions, have been filed in certain jurisdictions in which the plaintiffs allege that Sony Corporation and certain of its subsidiaries violated antitrust laws and seek recovery of damages and other remedies. All of these lawsuits have been settled, including the class actions brought by the direct and indirect purchasers in the United States, except one lawsuit which is still pending. Sony believes that final resolution of the pending proceeding will not have a material impact on Sony’s results of operations and financial position. In addition, Sony Corporation and certain of its subsidiaries are defendants or otherwise involved in other pending legal and regulatory proceedings. However, based upon the information currently available, Sony believes that the outcome from such legal and regulatory proceedings would not have a material impact on Sony’s results of operations and financial position. (4) Guarantees       Sony has issued guarantees that contingently require payments to guaranteed parties if certain specified events or conditions occur. The maximum potential amount of future payments under these guarantees as of March 31, 2020 amounted to 2,214 million yen. In addition to the above, Sony also issues contractual product warranties under which it generally guarantees the performance of products delivered and services rendered for a certain period or term. The changes in the product warranty liability for the fiscal years ended March 31, 2018, 2019 and 2020 are as follows:                             Yen in millions     Fiscal year ended March 31     2018     2019     2020   Balance at beginning of the fiscal year     57,694       44,717       33,005   Additional liabilities for warranties     32,179       23,041       21,448   Settlements (in cash or in kind)     (30,570 )     (26,326 )     (21,491 ) Changes in estimate for pre-existing warranty reserve     (16,802 )     (7,370 )     (562 ) Translation adjustments     2,216       (1,057 )     (593 )                           Balance at end of the fiscal year     44,717       33,005       31,807                                 The consideration received for extended warranty service, which is not a significant portion of the warranty activities provided by Sony, is excluded from the amounts in the table above.

For the fiscal   years ended March 31, 2019 and 2020, with respect to equity securities included in marketable securities and securities investments, Sony recorded net realized gains of 77,495 million yen and 20,176 million yen due to the sale of equity securities and net unrealized gains of 104,168 million yen and net   unrealized loss of 134,831 million yen due to revaluation of equity securities held as of March 31, 2019 and 2020, respectively. Gains or losses arising from equity securities held in the Financial Services segment are recorded in financial services revenue, and gains or losses arising from equity securities held in all segments other than the Financial Services segment are recorded in gain  (loss) on equity securities, net in the consolidated statement of income. Included in the gains and (losses) noted above were gains and (losses) recorded by Sony with respect to the equity securities held by Sony in Spotify Technology S.A. (“Spotify”). On April 3, 2018, Spotify was publicly listed for trading on the New York Stock Exchange. Sony owned 5.707% of Spotify’s shares at the time of the public listing. During the fiscal year ended March 31, 2019, Sony sold a portion of the Spotify shares that it owned for aggregate consideration of 82,616 million yen (768 million U.S. dollars) in cash proceeds. The sale of such shares, offset by costs to be paid to Sony’s artists and distributed labels and other transaction costs which directly related to the gains recognized from the sale of Spotify shares, resulted in a net pre-tax realized gain of 54,179 million yen (504 million U.S. dollars) recorded in gain on equity securities, net in the consolidated statement of income. The payments to Sony’s artists and distributed labels are included within Other in the cash flows from investing activities of the consolidated statement of cash flows. The remaining Spotify shares retained as of March 31, 2019 had a gross fair value of 78,947 million yen (711 million U.S. dollars), and the revaluation of such shares resulted in a pre-tax unrealized gain, net of costs to be paid to Sony’s artists and distributed labels and other costs which directly related to the gains recognized from the revaluation of Spotify shares, of 47,543 million yen (449 million U.S. dollars) recorded in gain on equity securities, net in the consolidated statement of income. During the fiscal year ended March 31, 2020, Sony did not sell any portion of the Spotify shares that it owned. The revaluation of the remaining Spotify shares retained as of March 31, 2020 resulted in a pre-tax unrealized loss, net of a decrease in costs to be paid to Sony’s artists and distributed labels, of 6,063 million yen (57 million U.S. dollars) recorded in loss on equity securities, net in the consolidated statements of income. The aggregate carrying amounts of securities that do not have readily determinable fair values  as of March 31, 2019 and 2020 totaled 25,720 million yen and 30,120 million yen, respectively. Sony recorded no upward adjustments for securities that do not have readily determinable fair values for   the fiscal year ended March 31, 2019 , and  upward adjustments of 1,070 million yen for securities that do not have readily determinable fair values for   the fiscal year ended March 31, 2020. Sony recorded downward adjustments (including impairments) of 4,285 million yen and 9,075 million yen for securities that do not have readily determinable fair values for the fiscal year s ended March 31, 2019 and 2020, respectively.

On July 21, 2015, Sony issued 120,000 million yen of 130% callable unsecured zero coupon convertible bonds with stock acquisition rights due 2022 (the “Zero Coupon Convertible Bonds”). The bondholders are entitled to stock acquisition rights effective from September 1, 2015 to September 28, 2022. The initial conversion price was 5,008.0 yen per common share. In addition to the standard anti-dilution provisions, the conversion price is reduced for a certain period before an early redemption triggered upon the occurrence of certain corporate events including a merger, corporate split and delisting event. The reduced amount of the conversion price will be determined by a formula that is based on the effective date of the reduction and Sony’s common stock price. The reduced conversion price ranges from 3,526.5 yen to 5,008.0 yen per common share. The conversion price is also adjusted for dividends in excess of 25 yen per common share per fiscal year. The conversion price has been adjusted to 4,982.5 yen per common share since June 10, 2020 because the payment of the total annual dividend per common share for the fiscal year ended March 31, 2020 was 45 yen, which is in excess of 25 yen. Sony has the option to redeem all of the Zero Coupon Convertible Bonds outstanding at 100% of the principal amount after July 21, 2020, if the closing sales price per share of Sony’s common stock on the Tokyo Stock Exchange is 130% or more of the conversion price of the Zero Coupon Convertible Bonds for 20 consecutive trading days. Sony was not required to bifurcate any of the embedded features contained in the Zero Coupon Convertible Bonds for accounting purposes. There are no significant adverse debt covenants under the Zero Coupon Convertible Bonds. In October 2019, Sony issued unsecured straight bonds in the aggregate principal amount of 100,000 million yen. Sony used all of the proceeds of the issued bonds for the repayment of debt.  There are no significant adverse debt covenants or cross-default provisions related to the other short-term borrowings and long-term debt.

Summary of significant accounting policies (Policies)	12 Months Ended
	Mar. 31, 2020
Accounting Policies [Abstract]
Basis of consolidation and accounting for investments in affiliated companies	Basis of consolidation and accounting for investments in affiliated companies - The consolidated financial statements include the accounts of Sony Corporation and its majority-owned subsidiary companies, general partnerships and other entities in which Sony has a controlling interest, and variable interest entities (“VIEs”) for which Sony is the primary beneficiary. All intercompany transactions and accounts are eliminated. Investments in business entities in which Sony does not have control, but has the ability to exercise significant influence over operating and financial policies, generally through 20-50% ownership, are accounted for under the equity method. In addition, investments in general partnerships in which Sony does not have a controlling interest and limited partnerships are also accounted for under the equity method if more than minor influence over the operation of the investee exists (generally through more than 3-5% ownership). When the interest in the partnership is so minor that Sony has no significant influence over the operation of the investee, the interest in the partnership is carried at fair value. Under the equity method, investments are stated at cost plus/minus Sony’s portion of equity in undistributed earnings or losses. Sony’s equity in current earnings or losses of such entities is reported net of income taxes and is included in operating income (loss) after the elimination of unrealized intercompany profits. If the value of an investment has declined and is judged to be other-than-temporary, the investment is written down to its estimated fair value. On occasion, a consolidated subsidiary or an affiliated company accounted for by the equity method may issue its shares to third parties in either a public or private offering or upon conversion of convertible debt to common stock at amounts per share in excess of or less than Sony’s average per share carrying value. With respect to such transactions, the resulting gains or losses arising from the change in ownership interest are recorded in earnings within the fiscal year in which the change in interest transactions occurs. Gains or losses that result from a loss of a controlling financial interest in a subsidiary are recorded in earnings along with fair value remeasurement gains or losses on any retained investment in the entity, while a change in interest in a consolidated subsidiary that does not result in a change in control is accounted for as a capital transaction and no gains or losses are recorded in earnings. The excess of the cost over the underlying net equity of investments in consolidated subsidiaries and affiliated companies accounted for on an equity basis is allocated to identifiable tangible and intangible assets and liabilities based on fair values at the date of acquisition. The unassigned residual value of the excess of the cost over Sony’s underlying net equity is recognized as goodwill as a component of the investment balance.
Use of estimates	Use of estimates - The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The most significant estimates include those used in determining the valuation of investment securities, valuation of inventories, fair values of long-lived assets, fair values of goodwill and other intangible assets, fair values of assets and liabilities assumed in business combinations, product warranty liability, pension and severance plans, valuation of deferred tax assets, uncertain tax positions, film costs, and insurance related liabilities. Actual results could significantly differ from those estimates. The timing and extent to which the spread of COVID-19 may negatively impact Sony’s business will depend on future developments, which are highly uncertain. This uncertainty could result in greater variability in accounting estimates and assumptions, including, but not limited to, those used in reviewing goodwill and long-lived assets for impairment and the valuation of deferred tax assets.
Translation of foreign currencies	Translation of foreign currencies - All asset and liability accounts of foreign subsidiaries and affiliates are translated into Japanese yen at appropriate fiscal year end exchange rates and all income and expense accounts are translated at exchange rates that approximate those rates prevailing at the time of the transactions. The resulting translation adjustments are accumulated as a component of accumulated other comprehensive income. Upon remeasurement of a previously held equity interest in accordance with the accounting guidance for business combinations achieved in stages, accumulated translation adjustments, if any, are included in earnings. Monetary assets and liabilities denominated in foreign currencies are translated at appropriate fiscal year end exchange rates and the resulting translation gains or losses are recognized into income.
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash - Cash and cash equivalents include all highly liquid investments, with original maturities of three months or less, that are readily convertible to known amounts of cash and are so near maturity that they present insignificant risk of changes in value because of changes in interest rates. Sony includes restricted cash within cash and cash equivalents in the statement of cash flows.
Marketable debt and equity securities	Marketable debt and equity securities - Debt securities designated as available-for-sale are carried at fair value with unrealized gains or losses included as a component of accumulated other comprehensive income, net of applicable taxes. Equity securities that have a readily determinable fair value, and debt securities classified as trading securities, are carried at fair value with unrealized gains or losses included in income. Debt securities that are expected to be held-to-maturity are carried at amortized cost. Individual securities classified as either available-for-sale or held-to-maturity are reduced to fair value by a charge to income when an other-than-temporary impairment is recognized. Realized gains and losses are determined on the average cost method and are reflected in income. Sony regularly evaluates its investment portfolio to identify other-than-temporary impairments of individual debt securities. Factors that are considered by Sony in determining whether an other-than-temporary decline in value has occurred include: the length of time and extent to which the market value of the security has been less than its original cost, the financial condition, operating results, business plans and estimated future cash flows of the issuer of the security, other specific factors affecting the market value, deterioration of the credit condition of the issuer, sovereign risk, and whether or not Sony is able to retain the investment for a period of time sufficient to allow for the anticipated recovery in market value. In evaluating the factors for debt securities designated as available-for-sale, Sony presumes a decline in value to be other-than-temporary if the fair value of the security is 20 percent or more below its original cost for an extended period of time (generally for a period of up to six months). This criterion is employed as a threshold to identify securities which may have a decline in value that is other-than-temporary. The presumption of an other-than-temporary impairment in such cases may be overcome if there is evidence to support that the decline is temporary in nature due to the existence of other factors which overcome the duration or magnitude of the decline. On the other hand, there may be cases where impairment losses are recognized when the decline in the fair value of the security is not more than 20 percent or such decline has not existed for an extended period of time, as a result of considering specific factors which may indicate that the decline in the fair value is other-than-temporary. When an other-than-temporary impairment of a held-to-maturity debt security has occurred, the amount of the other-than-temporary impairment recognized in income depends on whether Sony intends to sell the debt security or more likely than not will be required to sell the debt security before recovery of its amortized cost. If the debt security meets either of these two criteria, the other-than-temporary impairment is recognized in income, measured as the entire difference between the security’s amortized cost and its fair value at the impairment measurement date. For other-than-temporary impairment of the debt security that does not meet these two criteria, the net amount recognized in income is a credit loss, which equals the difference between the amortized cost of the debt security and its net present value calculated by discounting Sony’s best estimate of projected future cash flows at the effective interest rate implicit in the debt security prior to impairment. Any difference between the fair value and the net present value of the debt security at the impairment measurement date is recorded in accumulated other comprehensive income. Unrealized gains or losses on securities for which an other-than-temporary impairment is recognized in income are presented as a separate component of accumulated other comprehensive income.
Equity securities that do not have readily determinable fair values	Equity securities that do not have readily determinable fair values - Equity securities that do not have readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. If the value of equity securities that do not have readily determinable fair values is estimated to have declined and such decline is judged to be other-than-temporary, Sony recognizes the impairment of the investment and the carrying value is reduced to its fair value. Determination of impairment is based on the consideration of several factors, including operating results, business plans and estimated future cash flows. Fair value is determined through the use of various methodologies such as discounted cash flows, valuation of recent financings and comparable valuations of similar companies.
Allowance for doubtful accounts	Allowance for doubtful accounts - Sony maintains an allowance for doubtful accounts to reserve for potentially uncollectible receivables. Sony reviews accounts receivable by amounts due from customers which are past due to identify specific customers with known disputes or collectability issues. In determining the amount of the reserve, Sony makes judgments about the creditworthiness of customers based on past collection experience and ongoing credit risk evaluations.
Inventories	Inventories - Inventories in the Game & Network Services (“G&NS”), Music, Electronics Products & Solutions (“EP&S”) and Imaging & Sensing Solutions (“I&SS”) segments as well as non-film inventories for the Pictures segment are valued at cost, not in excess of the net realizable value – i.e., estimated selling price in the ordinary course of business less reasonably predictable costs of completion and disposal, cost being determined on the “average cost” basis.
Other receivables	Other receivables - Other receivables include receivables which relate to arrangements with certain component manufacturers whereby Sony procures goods, including product components, for these component manufacturers and is reimbursed for the related purchases. No revenue or profit is recognized on these transfers. Sony will repurchase the inventory at a later date from the component manufacturers as either finished goods inventory or as partially assembled product.
Film costs	Film costs - Film costs include direct production costs, production overhead and acquisition costs for both motion picture and television productions and are stated at the lower of unamortized cost or estimated fair value and classified as noncurrent assets. Film costs are amortized, and the estimated liabilities for residuals and participations are accrued using an individual-film-forecast method based on the ratio of current period actual revenues to the estimated remaining total revenues. Film costs also include broadcasting rights, which are recognized when the license period begins and the program is available for use, and consist of acquired programming to be aired on Sony’s worldwide channel network. Broadcasting rights are stated at the lower of unamortized cost or net realizable value, classified as either current or noncurrent assets based on timing of expected use. Broadcasting rights are amortized based on estimated usage or on a straight-line basis over the useful life, as appropriate, although broadcasting rights licensed under multi-year live-event sports programming agreements are generally amortized based on the ratio of the current period’s actual advertising revenue and an allocation of subscription fee revenue to the estimated total remaining attributable revenues. Estimates used in calculating the fair value of film costs and the net realizable value of broadcasting rights are based upon assumptions about future demand and market conditions and are reviewed on a periodic basis.
Property, plant and equipment and depreciation	Property, plant and equipment and depreciation - Property, plant and equipment are stated at cost. Depreciation is computed using the straight-line method. Useful lives for depreciation range from 2 to 50 years for buildings and from 2 to 10 years for machinery and equipment. Significant renewals and additions are capitalized at cost. Maintenance and repairs, and minor renewals and betterments are charged to income as incurred.
Leases	Leases - When entering into a contract, Sony determines whether an arrangement contains a lease at its inception. An arrangement contains a lease if it conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. Operating leases are included in operating lease right-of-use assets, current portion of long-term operating lease liabilities, and long-term operating lease liabilities on Sony’s consolidated balance sheets. Finance leases are included in finance lease right-of-use assets, current portion of long-term debt, and long-term debt on Sony’s consolidated balance sheets. Right-of-use assets represent Sony’s right to use an underlying asset for the lease term and lease liabilities represent Sony’s obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Right-of-use assets also include any lease payments or initial direct costs incurred on or before the commencement date and excludes lease incentives. In determining the present value of lease payments, Sony generally uses its incremental borrowing rate, as the implicit rate is not available for most of its leases. Sony determines its incremental borrowing rate based on the estimated rate of interest for collateralized borrowing, taking into account the lease term and the economic environment of each country or region at commencement date. The lease terms include options to extend or terminate the lease when it is reasonably certain that Sony will exercise that option. Lease expense for operating leases recorded on the balance sheet is recognized on a straight-line basis over the lease term. Sony accounts for the lease and non-lease components of all underlying asset classes as a single lease component. Sony has applied the short-term lease exception for leases with a term of one year or less, where right-of-use assets and lease liabilities are not recognized and the expense is recognized on a straight-line basis . As of April 1, 2019, Sony adopted Accounting Standards Update (“ASU”) 2016-02, which amends leasing guidance, on a modified retrospective basis with no restatement of comparative periods. Prior to the adoption of ASU 2016-02 on April 1, 2019, right-of-use assets and lease liabilities for operating leases were not recognized in Sony’s consolidated balance sheet. For the detailed effect of the adoption of the new standard on Sony’s results of operations and financial position, refer to Note 2 (2) Recently adopted accounting pronouncements.
Goodwill and other intangible assets	Goodwill and other intangible assets - Goodwill and indefinite lived intangible assets are tested annually for impairment during the fourth quarter of the fiscal year and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value below its carrying amount. Such an event or change in circumstances would include unfavorable variances from established business plans, significant changes in forecasted results or volatility inherent to external markets and industries, which are periodically reviewed by Sony’s management. In the fourth quarter of the fiscal year ended March 31, 2020, Sony elected not to perform an optional qualitative assessment of goodwill and instead proceeded directly to a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. Reporting units are Sony’s operating segments or one level below the operating segments. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered impaired. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, not to exceed the total amount of goodwill allocated to the reporting unit. Indefinite lived intangible assets are tested for impairment by comparing the fair value of the intangible asset with its carrying value, and if the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. The fair value of a reporting unit or indefinite lived intangible asset is generally determined using a discounted cash flow analysis. This approach uses significant estimates and assumptions, including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates, earnings multiples, the determination of appropriate comparable entities and the determination of whether a premium or discount should be applied to comparables. Consideration is also given to Sony’s market capitalization in relation to the sum of the calculated fair values of the reporting units, including reporting units with no goodwill, and taking into account corporate level assets and liabilities not assigned to individual reporting units as well as a reasonable control premium. The assumptions used for projected future cash flows and the timing of such cash flows are based on the forecast and mid-range plan (“MRP”) of each reporting unit and take into account such factors as historical experience, market and industry information, and current and forecasted economic conditions. Perpetual growth rates are utilized to determine a terminal cash flow value and are generally set after the three-year forecasted period for the MRP. Certain reporting units, such as those in the Pictures segment, utilize longer forecast periods and base the terminal value on an exit price using an earnings multiple applied to the final year of the forecasted earnings, which also takes into consideration a control premium. Discount rates are derived from the weighted average cost of capital of market participants in similar businesses. Management believes that the assumptions used to estimate the fair value in the goodwill impairment tests are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower than currently anticipated cash flows and fair values due to unforeseen changes in assumptions could negatively affect the valuations, which may result in Sony recognizing impairment charges for goodwill and indefinite lived intangible assets in the future. When a business within a reporting unit is disposed of, goodwill is allocated to the disposed business using the relative fair value method. Intangible assets with finite useful lives mainly consist of patent rights, know-how, license agreements, customer relationships, trademarks, software to be sold, leased or otherwise marketed, internal-use software, music catalogs, artist contracts, and television carriage contracts (broadcasting agreements). Patent rights, know-how, license agreements, trademarks, software to be sold, leased or otherwise marketed, and internal-use software are generally amortized on a straight-line basis over 3 to 10 years. Customer relationships, music catalogs, artist contracts and television carriage contracts (broadcasting agreements) are generally amortized on a straight-line basis over 10 to 44 years.
Capitalized software	Capitalized software - The costs related to establishing the technological feasibility of software to be sold, leased or otherwise marketed are expensed as incurred as a part of research and development in cost of sales. Costs that are incurred to produce the finished product after technological feasibility is established are capitalized and amortized to cost of sales over the estimated economic life, which is generally three years. The technological feasibility of game software is established when the product master is completed. Consideration to capitalize game software development costs before this point is limited to the development costs of games for which technological feasibility can be proven at an earlier stage. At each balance sheet date, Sony performs reviews to ensure that unamortized capitalized software costs remain recoverable from future profits of the related software products. The costs incurred for internal-use software during the application development stage are capitalized and amortized, mainly to selling, general and administrative expenses, on a straight-line basis over the estimated useful life. Costs related to the preliminary project stage and post implementation activities are expensed as incurred.
Deferred insurance acquisition costs	Deferred insurance acquisition costs - Costs that vary with and are directly related to the acquisition or renewal of insurance policies are deferred as long as they are recoverable. The deferred insurance acquisition costs include such items as commissions, medical examination costs and inspection report fees, and are subject to recoverability testing at least annually to ensure that the capitalized amounts do not exceed the present value of anticipated gross profits or premiums less benefits and maintenance expenses, as applicable. The deferred insurance acquisition costs for traditional life insurance contracts are amortized over the premium-paying period of the related insurance policies using assumptions consistent with those used in computing policy reserves. The deferred insurance acquisition costs for non-traditional life insurance contracts are amortized over the expected life at a constant rate based on the present value of the estimated gross profit. Investment yields, mortality rates, lapse rates and discount rates are used as important assumptions for the present value of the estimated gross profit.
Product warranty	Product warranty - Sony provides for the estimated cost of product warranties at the time revenue is recognized. The product warranty is calculated based upon product sales, estimated probability of failure and estimated cost per claim. The variables used in the calculation of the provision are reviewed on a periodic basis.
Future insurance policy benefits	Future insurance policy benefits - Liabilities for future insurance policy benefits are primarily comprised of the present value of estimated future payments to policyholders. These liabilities are computed by the net level premium method based upon the assumptions as to future investment yield, morbidity, mortality, withdrawals and other factors. These assumptions are reviewed on a periodic basis. Liabilities for future policy benefits includes the liabilities for the minimum guarantee benefits of variable annuities and variable life insurance contracts. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for future insurance policy benefits.
Policyholders' account in the life insurance business	Policyholders’ account in the life insurance business - Liabilities for policyholders’ account in the life insurance business represent the contract value that has accrued to the benefit of the policyholders as of the balance sheet date. This liability is generally equal to the accumulated account deposits, plus interest credited, less policyholder withdrawals and other charges assessed against the account balances. Liabilities for policyholders’ account in the life insurance business includes the liabilities related to the variable annuities and variable life insurance contracts with minimum guarantee benefits. As discussed below in “Fair value measurement,” Sony elected the fair value option for certain of these liabilities for policyholders’ account in the life insurance business.
Impairment of long-lived assets	Impairment of long-lived assets - Sony reviews the recoverability of the carrying value of its long-lived assets held and used, other than goodwill and intangible assets with indefinite lives, and assets to be disposed of, whenever events or changes in circumstances indicate that the individual carrying amount of an asset or asset group may not be recoverable. Long-lived assets to be held and used are reviewed for impairment by comparing the carrying value of the asset or asset group with their estimated undiscounted future cash flows. If the cash flows are determined to be less than the carrying value of the asset or asset group, an impairment loss would be recognized during the period for the amount by which the carrying value of the asset or asset group exceeds estimated fair value. Long-lived assets that are to be disposed of other than by sale are considered held and used until they are disposed of. Long-lived assets that are to be disposed of by sale are reported at the lower of their carrying value or fair value less cost to sell and are not depreciated. Fair value is determined using the present value of estimated net cash flows or comparable market values. This approach uses significant estimates and assumptions including projected future cash flows, the timing of such cash flows, discount rates reflecting the risk inherent in future cash flows, perpetual growth rates applied to determine terminal values, determination of appropriate market comparables and the determination of whether a premium or discount should be applied to comparables. Management believes that the estimates of future cash flows and fair values are reasonable, including, but not limited to, the potential impacts arising from the spread of COVID-19. As the extent and duration of the impacts from COVID-19 remain unclear, Sony’s estimates and assumptions may evolve as conditions change. Actual results could differ from those estimates. As a result, changes in estimates resulting in lower future cash flows and fair values due to unforeseen changes in Sony’s businesses or assumptions could negatively affect the valuations of long-lived assets.
Fair value measurement	Fair value measurement - Sony measures fair value as an exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Sony has elected the fair value option in the banking business for certain foreign securities. The election was made to mitigate accounting mismatches related to fluctuations of foreign exchange rates by allowing the gains and losses on the translation of these securities to be included in current earnings. Sony has also elected the fair value option for certain future insurance policy benefits and policyholders’ account in the life insurance business which are not normally measured at fair value. The election was made to mitigate accounting mismatches related to the changes in the fair value between liabilities for those future insurance policy benefits and policyholders’ account due to changes in the minimum guarantee risk of contracts of variable annuities with minimum guarantee benefits, and the underlying investment managed for policyholders and derivatives. Changes in fair value resulting from changes in instrument-specific credit risk were estimated by incorporating the certain subsidiary’s current credit spreads, and are recognized in other comprehensive income, net of tax. The accounting guidance for fair value measurements specifies a hierarchy of inputs to valuation techniques based on the extent to which inputs used in measuring fair value are observable in the market. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Sony’s assumptions about the assumptions that market participants would use in pricing the asset or liability. Observable market data is used if such data is available without undue cost and effort. Each fair value measurement is reported in one of three levels which is determined by the lowest level input that is significant to the fair value measurement in its entirety. These levels are:           Level 1   —   Inputs are unadjusted quoted prices for identical assets and liabilities in active markets.           Level 2   —   Inputs are based on observable inputs other than level 1 prices, such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.           Level 3   —   One or more significant inputs are unobservable.         When available, Sony uses unadjusted quoted market prices in active markets to measure fair value and classifies such items within level 1. If quoted market prices are not available, fair value is based upon internally developed valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates, currency rates and option volatilities. Items valued using internally generated models are classified according to the lowest level input that is significant to the valuation. For certain financial assets and liabilities, Sony determines fair value using third-party information such as indicative quotes from dealers and quantitative input from investment advisors following Sony’s established valuation procedures including validation against internally developed prices. Additionally, Sony considers both counterparty credit risk and Sony’s own creditworthiness in determining fair value. Sony attempts to mitigate credit risk to third parties by entering into netting agreements and actively monitoring the creditworthiness of counterparties and its exposure to credit risk through the use of credit limits and by selecting major international banks and financial institutions as counterparties. Transfers between levels are deemed to have occurred at the beginning of the interim period in which the transfers occur.
Derivative financial instruments	Derivative financial instruments - All derivatives are recognized as either assets or liabilities in the consolidated balance sheets at fair value on a gross basis. Changes in the fair value of derivative financial instruments are either recognized periodically in income or stockholders’ equity (as a component of accumulated other comprehensive income), depending on whether the derivative financial instrument qualifies as a hedge and the derivative is being used to hedge changes in fair value or cash flows. The accounting guidance for hybrid financial instruments permits an entity to elect fair value remeasurement for any hybrid financial instrument if the hybrid instrument contains an embedded derivative that would otherwise be required to be bifurcated and accounted for separately under accounting guidance for derivative instruments and hedging activities. The election to measure the hybrid instrument at fair value is made on an instrument-by-instrument basis and is irreversible. Certain subsidiaries in the Financial Services segment had hybrid financial instruments, disclosed in Note 7 as debt securities, that contain embedded derivatives where the entire instrument was carried at fair value. In accordance with accounting guidance for derivative instruments and hedging activities, various derivative financial instruments held by Sony are classified and accounted for as described below. Fair value hedges Changes in the fair value of derivatives designated as fair value hedges for recognized assets or liabilities or unrecognized firm commitments are recognized in earnings as offsets to changes in the fair value of the related hedged assets or liabilities. Cash flow hedges Changes in the fair value of derivatives designated as cash flow hedges for forecasted transactions or exposures associated with recognized assets or liabilities are initially recorded in other comprehensive income and reclassified into earnings when the hedged transaction affects earnings. The time value component of the fair value of option contracts is excluded from the assessment of hedge effectiveness and recognized in earnings on a straight-line basis over the life of the hedging instruments. Any difference between the change in fair value of the excluded component and the accumulated amount recognized in earnings on a straight-line basis is recognized in other comprehensive income. Derivatives not designated as hedges Changes in the fair value of derivatives that are not designated as hedges are recognized immediately in earnings. Assessment of hedges When applying hedge accounting, Sony formally documents all hedging relationships between the derivatives designated as hedges and the hedged items, as well as its risk management objectives and strategies for undertaking various hedging activities. Sony links all hedges that are designated as fair value or cash flow hedges to specific assets or liabilities on the consolidated balance sheets or to the specific forecasted transactions. Sony also assesses, both at the inception of the hedge and on an on-going basis, whether the derivatives that are designated as hedges are highly effective in offsetting changes in fair value or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge, Sony discontinues hedge accounting.
Stock-based compensation	Stock-based compensation - Sony accounts for stock-based compensation using the fair value - based method and the expense is mainly included in selling, general and administrative expenses. Sony accounts for its stock acquisition rights plan using the fair value measured on the date of grant using the Black-Scholes option-pricing model. The stock acquisition rights plan is recognized, net of an estimated forfeiture rate, over the requisite service period using the accelerated method of amortization for grants with graded vesting. The estimated forfeiture rate is based on Sony’s historical experience in the stock acquisition rights plans where the majority of the vesting terms have been satisfied.
Revenue recognition	Revenue recognition - Sony recognizes revenue in an amount that reflects the consideration Sony expects in exchange for satisfying performance obligations to transfer the goods or services promised in contracts with customers. This is in accordance with the following steps: Step 1: Identify the contract(s) with a customer. Step 2: Identify the performance obligations in the contract. Step 3: Determine the transaction price. Step 4: Allocate the transaction price to the performance obligations in the contract. Step 5: Recognize revenue when (or as) Sony satisfies a performance obligation. Sony owns a variety of intellectual property throughout segments and recognizes revenue through the licensing of such intellectual property. Sony has both functional and symbolic intellectual property. The licensing of functional intellectual property grants a customer a right to use Sony’s intellectual property as it exists at a point in time, and Sony satisfies its performance obligation at the point in time when the customer obtains control and is entitled to benefit from the license. The licensing of symbolic intellectual property grants a customer a right to access Sony’s intellectual property over time, and Sony satisfies its performance obligation over the license period as Sony maintains the intellectual property. Incremental costs of obtaining a contract and costs to fulfill a contract are recognized as assets when Sony expects to recover these costs. The incremental costs of obtaining a contract are those costs that would not have been incurred if the contract had not been obtained. Costs to fulfill a contract are those costs that are directly related to a contract or to an anticipated contract and that generate or enhance resources for Sony to satisfy its performance obligations. Sony applies a practical expedient and recognizes the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that would have been recognized is one year or less. Performance obligations in contracts for the EP&S and I&SS segments are primarily to deliver various kinds of electronic equipment, instruments and devices to customers. Revenues from these performance obligations are generally recognized when a promised good is delivered to a customer. However, if the sales contract contains a customer acceptance provision, then revenues are recognized when the customer accepts the promised good or when a deemed acceptance occurs by the lapse of time. Revenues are also recognized over time, primarily from the provision of internet broadband network services to subscribers over the subscription period. Revenues are recognized net of anticipated returns and sales incentives. Within the G&NS segment, revenues from hardware, peripherals and software discs are recognized when performance obligations are satisfied by transferring control to the retailer/distributor, net of anticipated returns, sales incentives and cooperative advertising obligations. Revenues from platform licensing to publishers are recognized when physical software discs are delivered. Revenues from digital game content, which is licensed functional intellectual property, are recognized when the digital content is made available for use by the licensee via an online platform, net of anticipated sales incentives and credit card chargebacks. Revenues from digital game content involving multiple performance obligations, such as obligations to make content available on future dates, are allocated to each performance obligation based on the relative standalone selling prices that are observable in the market or Sony’s best estimate. Revenues from subscription fees for digital subscription services are recognized over the subscription period. Within the Music segment, Sony licenses intellectual property that transfer to a customer either a right to use Sony’s intellectual property as it exists at the point in time in which the license is granted, or a right to access Sony’s intellectual property as it exists throughout the license period. Revenues are recognized when the customer has the right to use or access the intellectual property and obtains control of the use or access of that license. Digital revenues include revenues from contracts with digital streaming services typically recognized as a single performance obligation, which is ongoing access to intellectual property in an evolving library of content over the contract term, predicated on: (1) the business practice and contractual ability to remove specific content without a requirement to replace the content and without impact to minimum royalty guarantees and (2) the contracts not containing a specific listing of content subject to the license. For these contracts, revenues are recognized on the basis of sales and usage royalties, except where there is an amount of a minimum royalty guarantee that is not expected to be recouped, or a fixed fee, which is recognized on a straight-line basis over the term of the contract. Revenues from the sale of physical product such as CDs, net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public. Within the Pictures segment, revenues from the theatrical exhibition of motion pictures are recognized as the customer exhibits the film. Revenues from the licensing of motion picture and television programming for pay and free television exhibition and other markets are recognized when the product is available for use by the licensee. Revenues for motion picture and television program licensing arrangements involving multiple performance obligations, for example a fee for multiple titles, territories or availability dates, are allocated based on the relative standalone selling price of each performance obligation using Sony’s best estimate based on available information such as market conditions and internal pricing guidelines. Each individual motion picture or television programming product delivered generally represents a separate performance obligation. Licensing revenue associated with certain renewals or extensions of existing agreements for motion pictures and television programming is recognized when the licensee can use and benefit from the content under the renewal or extension. Licensing revenue associated with minimum guarantees for symbolic intellectual property is recognized ratably over the license term. For home entertainment distribution, revenues from the sale of physical product such as DVDs and Blu-ray Disc TM , net of anticipated returns and sales incentives, are recognized when delivery has occurred and the product is available for sale to the public. Revenues from electronic sell-through and video-on-demand are recognized when the product is made available for viewing via digital distribution platforms. Revenues from the sale of broadcast advertising are recognized when the advertisement is aired, and the performance obligation in these arrangements is the delivery of advertising spots and may include a guaranteed amount of impressions. When a guarantee for a number of impressions is not achieved, revenues are not recognized until additional advertising spots are delivered to provide the guaranteed impressions. Revenues from subscription fees received by television networks are recognized when the service is provided. The performance obligation under network subscription arrangements is a license of functional intellectual property that is satisfied as programming is provided over the term of the arrangement. Traditional life insurance policies that the life insurance subsidiary underwrites, most of which are categorized as long-duration contracts, mainly consist of whole life, term life and accident and health insurance contracts. Premiums from these policies are reported as revenue when due from policyholders. Amounts received as payment for non-traditional contracts such as interest sensitive whole life contracts, individual annuity contracts and other contracts without life contingencies are recognized in policyholders’ account in the life insurance business. Revenues from these contracts are comprised of fees earned for administrative and contract-holder services, which are recognized over the period of the contracts, and included in financial services revenue. Property and casualty insurance policies that the non-life insurance subsidiary underwrites are primarily automotive insurance contracts which are categorized as short-duration contracts. Premiums from these policies are reported as revenue over the period of the contract in proportion to the amount of insurance protection provided. Revenue is recognized net of any taxes collected from customers and subsequently remitted to governmental authorities.
Cost of sales	Cost of sales - Costs classified as cost of sales relate to the producing and manufacturing of products and include items such as material cost, subcontractor cost, depreciation of fixed assets, amortization of intangible assets, personnel expenses, research and development costs, and amortization of film costs related to motion picture and television productions.
Research and development costs	Research and development costs - Research and development costs, included in cost of sales, include items such as salaries, personnel expenses and other direct and indirect expenses associated with research and product development. Research and development costs are expensed as incurred.
Selling, general and administrative	Selling, general and administrative - Costs classified as selling expenses relate to promoting and selling products and include items such as advertising, promotion, shipping and warranty expenses. General and administrative expenses include operating items such as officers’ salaries, personnel expenses, depreciation of fixed assets, office rental for sales, marketing and administrative divisions, a provision for doubtful accounts and amortization of intangible assets.
Financial services expenses	Financial services expenses - Financial services expenses include a provision for policy reserves and amortization of deferred insurance acquisition costs, and all other operating costs, such as personnel expenses, depreciation of fixed assets, and office rental of subsidiaries, in the Financial Services segment.
Advertising costs	Advertising costs - Advertising costs are expensed when the advertisement or commercial appears in the selected media.
Shipping and handling costs	Shipping and handling costs - The majority of shipping and handling, warehousing and internal transfer costs for finished goods are included in selling, general and administrative expenses. An exception to this is in the Pictures segment where such costs are charged to cost of sales as they are an integral part of producing and distributing motion pictures and television programming. All other costs related to Sony’s distribution network are included in cost of sales, including inbound freight charges, purchasing and receiving costs, inspection costs and warehousing costs for raw materials and in-process inventory. Shipping and handling activities that occur after control of the related good transfers are treated as separate performance obligations. Amounts paid by customers for shipping and handling costs are included in net sales.
Income taxes	Income taxes - The provision for income taxes is computed based on the pretax income included in the consolidated statements of income, and the tax liability attributed to undistributed earnings of subsidiaries and affiliated companies accounted for by the equity method expected to be remitted in the foreseeable future. The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Carrying amounts of deferred tax assets require a reduction by a valuation allowance if, based on the available evidence, it is more likely than not that such assets will not be realized. Accordingly, the need to establish valuation allowances for deferred tax assets is assessed periodically with appropriate consideration given to all positive and negative evidence related to the realization of the deferred tax assets. Management’s judgments related to this assessment consider, among other matters, the nature, frequency and severity of current and cumulative losses on an individual tax jurisdiction basis, forecasts of future profitability after consideration of uncertain tax positions, excess of appreciated asset value over the tax basis of net assets, the duration of statutory carryforward periods, the past utilization of net operating loss carryforwards prior to expiration, as well as prudent and feasible tax planning strategies which would be employed by Sony to prevent net operating loss and tax credit carryforwards from expiring unutilized. Sony records assets and liabilities for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Sony continues to recognize interest and penalties, if any, with respect to income taxes, including unrecognized tax benefits, as interest expense and as income tax expense, respectively, in the consolidated statements of income. The amount of income taxes Sony pays is subject to ongoing audits by various taxing authorities, which may result in proposed assessments. In addition, several significant items related to intercompany transfer pricing are currently the subject of negotiations between taxing authorities in different jurisdictions as a result of pending advance pricing agreement applications and competent authority requests. Sony’s estimate for the potential outcome for any uncertain tax issues is judgmental and requires significant estimates. Sony assesses its income tax positions and records tax benefits for all years subject to examinations based upon the evaluation of the facts, circumstances and information available at that reporting date. For those tax positions for which it is more likely than not that a tax benefit will be sustained, Sony records the amount that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. If Sony does not believe that it is more likely than not that a tax benefit will be sustained, no tax benefit is recognized. However, Sony’s future results may include favorable or unfavorable adjustments to Sony’s estimated tax liabilities due to closure of income tax examinations, the outcome of negotiations between taxing authorities in different jurisdictions, new regulatory or judicial pronouncements or other relevant events. As a result, the amount of unrecognized tax benefits, and the effective tax rate, may fluctuate significantly. The U.S. Tax Cuts and Jobs Act of 2017 (the “U.S. Tax Reform Act”) subjects a U.S. entity to tax on Global Intangible Low Tax Income (“GILTI”) earned by its foreign subsidiaries. Sony has elected to account for GILTI as a current period expense when incurred.
Net income (loss) attributable to Sony Corporation's stockholders per share ("EPS")	Net income (loss) attributable to Sony Corporation’s stockholders per share (“EPS”) - Basic EPS is computed based on the weighted-average number of shares of common stock outstanding during each period. The computation of diluted EPS reflects the maximum possible dilution from conversion, exercise, or contingent issuance of securities. All potentially dilutive securities are excluded from the calculation in a situation where there is a net loss attributable to Sony Corporation’s stockholders.
Recently adopted accounting pronouncements	Leases - In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU  2016-02, which amends the accounting guidance for leases. The ASU requires substantially all leases to be recognized on the balance sheet. Sony has adopted this ASU effective April 1, 2019, on a modified retrospective basis with no restatement of comparative periods. Sony has elected the package of practical expedients for leases that expired or existed prior to the adoption date. As a result, Sony did not reassess whether any expired or existing contracts are or contain leases, the lease classification for any expired or existing leases, or whether initial direct costs for any existing leases qualify for capitalization. In addition, Sony has applied the short-term lease exception. As a result of the adoption of this ASU, Sony recognized 316,923 million yen of operating lease right-of-use assets and 341,251 million yen of lease liabilities for operating leases on the consolidated balance sheets at April 1, 2019. This impact is mainly due to operating leases of real estate. The difference of 24,328 million yen between right-of-use assets and lease liabilities represents deferred rent for leases that existed as of the date of adoption, which was offset against the opening balance of operating lease right-of-use assets. Finance lease   right-of-use assets which are included in property, plant and equipment in the consolidated balance sheets for the fiscal year ended March 31, 2019, are now presented as finance lease right-of-use assets from April 1, 2019 onward. Premium amortization on purchased callable debt securities - In March 2017, the FASB issued ASU 2017-08, which requires certain premiums on callable debt securities to be amortized to the earliest call date. The amortization period for callable debt securities purchased at a discount will not be affected. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position. Targeted improvements to accounting for hedging activities - In August 2017, the FASB issued ASU 2017-12, which made targeted improvements to the accounting for hedging activities. The amendments in this update simplify certain aspects of hedge accounting for both non-financial and financial risks and better align the recognition and measurement of hedge results with an entity’s risk management activities. This ASU also amends certain presentation and disclosure requirements for hedging activities and changes how an entity assesses hedge effectiveness. This ASU was effective for Sony as of April 1, 2019. The adoption of this ASU did not have a material impact on Sony’s results of operations and financial position.
Recent accounting pronouncements not yet adopted	(3) Recent accounting pronouncements not yet adopted                         Measurement of credit losses on financial instruments - In June 2016, the FASB issued ASU 2016-13, which amends the accounting guidance for credit losses on financial instruments. The ASU requires the consideration of all available relevant information when estimating expected credit losses, including past events, current conditions and forecasts and their implications for expected credit losses. This ASU is effective for Sony as of April 1, 2020. The adoption of this ASU is not expected to have a material impact on Sony’s results of operations and financial position. Improvements to Accounting for Costs of Films and License Agreements for Program Materials - In March 2019, the FASB issued ASU 2019-02, which updates the guidance for the capitalization of film costs associated with episodic television series, requires the use of fair value rather than net realizable value when determining potential impairments of broadcasting rights, and modifies the presentation and disclosure requirements for films and broadcasting rights. In addition, upon capitalization of film costs entities are required to determine qualitatively whether the predominant monetization strategy is on a title-by-title basis or together with other films and/or broadcast rights as part of a film group, such as in the case of a release of a film as part of a library of content on a streaming service. In the case of a film group, impairments are evaluated at the overall film group level rather than the individual title level. This ASU is effective for Sony as of April 1, 2020 and is applied on a prospective basis. Upon adoption, Sony will reclassify  approximately 24.1 b illion yen of broadcasting rights in the Pictures segment and  ap proximately  7.4   b illion yen of animation film production costs in the Music segment included in inventor ies  to film costs. Targeted Improvements to the Accounting for Long-Duration Contracts - In August 2018, the FASB issued ASU 2018-12, which revises the accounting for certain long-duration insurance contracts, and in November 2019, the FASB issued ASU 2019-09 to defer the effective date of ASU 2018-12 to January 1, 2022. The ASU prescribes comprehensive changes to recognition and measurement of certain long-duration insurance contracts and assumptions and introduces certain financial statement presentation requirements, as well as significant additional qualitative and quantitative disclosures. This ASU will be effective for Sony as of April 1, 2022. The impact of this ASU on Sony’s results of operations and financial position is being evaluated. Disclosures for Fair Value Measurement - In August 2018, the FASB issued ASU 2018-13, which amends disclosure requirements related to fair value measurement. This ASU is effective for Sony as of April 1, 2020. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position. Disclosures for Defined Benefit Plans - In August 2018, the FASB issued ASU 2018-14, which amends disclosure requirements related to defined benefit pension and other postretirement plans. This ASU is effective for Sony as of April 1, 2020 and will be applied on a retrospective basis. Since this ASU only impacts disclosures, the adoption will have no impact on Sony’s results of operations and financial position. Income Taxes - In December 2019, the FASB issued ASU 2019-12, which simplifies the accounting requirements for income taxes. This ASU will be effective for Sony as of April 1, 2021 and amendments within this ASU are required to be applied on a prospective basis, except certain amendments must be applied on a retrospective or modified retrospective basis. The impact of this ASU on Sony’s results of operations and financial position is being evaluated. Reference Rate Reform - In March 2020, the FASB issued ASU 2020-04, which provides optional relief for certain contracts impacted by reference rate reform. The relief provided by the amendments is permitted to be adopted any time through December 31, 2022. Sony is still evaluating the impact of reference rate reform and whether to apply the optional relief.
Reclassifications	(4) Reclassifications                       Certain reclassifications of the financial statements and accompanying footnotes for the fiscal years ended March 31, 2018 and 2019 have been made to conform to the presentation for the fiscal year ended March 31, 2020.

Share-based Payment Arrangement [Abstract]
Stock-based compensation plans	17. Stock-based compensation plans               The stock-based compensation expense for the fiscal years ended March 31, 2018, 2019 and 2020 was 5,249 million yen, 5,499 million yen and 5,958 million yen, respectively. Sony has a stock-based compensation incentive plan for selected directors, corporate executive officers and employees in the form of a stock acquisition rights plan. The stock acquisition rights generally have three year graded vesting schedules and are exercisable up to ten years from the date of grant. The total cash received from exercises under all of the stock acquisition rights plans during the fiscal years ended March 31, 2018, 2019 and 2020 was 7,129 million yen, 12,757 million yen and 7,560 million yen, respectively. Sony issued new shares of common stock upon exercise of these rights. The weighted-average fair value per share at the date of grant of stock acquisition rights granted during the fiscal years ended March 31, 2018, 2019 and 2020 was 2,045 yen, 1,593 yen and 1,864 yen, respectively. The fair value of stock acquisition rights granted on the date of grant and used to recognize compensation expense for the fiscal years ended March 31, 2018, 2019 and 2020 was estimated using the Black-Scholes option-pricing model with the following weighted-average assumptions:                             Fiscal year ended March 31             2018                     2019                     2020           Weighted-average assumptions                   Risk-free interest rate     1.14 %     1.37 %     0.70 % Expected lives     6.55  years     5.98  years     5.73  years Expected volatility *     38.49 %     32.52 %     29.30 % Expected dividends     0.40 %     0.35 %     0.32 %                 * Expected volatility was based on the historical volatilities of Sony Corporation’s common stock over the expected life of the stock acquisition rights.               A summary of the activities regarding the stock acquisition rights plan during the fiscal year ended March 31, 2020 is as follows:                                     Fiscal year ended March 31, 2020     Number of shares     Weighted- average exercise price     Weighted- average remaining life     Total intrinsic value         Yen     Years     Yen in millions   Outstanding at beginning of the fiscal year     12,213,900       3,665               Granted     3,279,700       6,669               Exercised     2,294,900       3,294               Forfeited or expired     322,000       5,500                                                 Outstanding at end of the fiscal year     12,876,700       4,982       7.52       19,459                                     Exercisable at end of the fiscal year     6,235,700       3,581       6.43       15,552                                                   The total intrinsic value of shares exercised under the stock acquisition rights plan during the fiscal years ended March 31, 2018, 2019 and 2020 was 6,970 million yen, 13,325 million yen and 7,575 million yen, respectively. As of March 31, 2020, there was 5,912  million yen   of total unrecognized compensation expense related to nonvested stock acquisition rights. This expense is expected to be recognized over a weighted-average period of 1.97 years.

Fair value measurements	12 Months Ended
	Mar. 31, 2020
Fair Value Disclosures [Abstract]
Fair value measurements	13. Fair value measurements           As discussed in Note 2, assets and liabilities subject to the accounting guidance for fair value measurements held by Sony are classified and accounted for as described below. (1) Assets and liabilities that are measured at fair value on a recurring basis           The following section describes the valuation techniques used by Sony to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Debt securities, equity securities, and other investments Where quoted prices are available in an active market, securities are classified in level 1 of the fair value hierarchy. Level 1 securities include exchange-traded equities. If quoted market prices are not available for the specific security or the market is inactive, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows and mainly classified in level 2 of the hierarchy. Level 2 securities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, such as the majority of government bonds and corporate bonds. In certain cases where there is limited activity or less transparency around inputs to the valuation, securities are classified within level 3 of the fair value hierarchy. Level 3 securities primarily include certain securitized products, certain hybrid financial instruments, certain private equity investments, and certain domestic and foreign corporate bonds not classified within level 1 or level 2. Derivatives Exchange-traded derivatives valued using quoted prices are classified within level 1 of the fair value hierarchy. However, few classes of derivative contracts are listed on an exchange; thus, the majority of Sony’s derivative positions are valued using internally developed models that use as their basis readily observable market parameters — i.e., parameters that are actively quoted and can be validated to external sources, including industry pricing services. Depending on the types and contractual terms of derivatives, fair value can be modeled using a series of techniques, such as the Black-Scholes option pricing model, which are consistently applied. Where derivative products have been established for some time, Sony uses models that are widely accepted in the financial services industry. These models reflect the contractual terms of the derivatives, including the period to maturity, and market-based parameters such as interest rates, volatility, and the credit rating of the counterparty. Further, many of these models do not contain a high level of subjectivity as the techniques used in the models do not require significant judgment, and inputs to the model are readily observable from actively quoted markets. Such instruments are generally classified within level 2 of the fair value hierarchy. In determining the fair value of Sony’s interest rate swap derivatives, Sony uses the present value of expected cash flows based on market observable interest rate yield curves commensurate with the term of each instrument. For foreign currency derivatives, Sony’s approach is to use forward contract and option valuation models employing market observable inputs, such as spot currency rates, time value and option volatilities. These derivatives are classified within level 2 since Sony primarily uses observable inputs in its valuation of its derivative assets and liabilities. Future insurance policy benefits and policyholders’ account in the life insurance business In determining the fair value of future insurance policy benefits and policyholders’ account in the life insurance business to which Sony applies the fair value option, Sony uses the present value of future expected cash flows based on mortality rates, lapse rates, discount rates, investment yield and various actuarial assumptions. These are classified within level 3 since Sony primarily uses unobservable inputs in its valuation. In determining the fair value of liability for the minimum guarantee benefits of variable annuities, Sony uses mortality rates (0.004%~44.865%), lapse rates (1.000 % ~7.500%), and discount rates (-0.061%~1.433%) as significant unobservable inputs. The fair value of the minimum guarante e   accumulation benefits, which is the primary minimum guarantee risk, generally declines with higher mortality rates, higher lapse rates, or higher discount rates. The fair value of Sony’s assets and liabilities that are measured at fair value on a recurring basis at March 31, 2019 and 2020 are as follows.

In the consolidated balance sheets, 2,386 million yen are included as marketable securities for the fiscal years ended March 31, 2020 and 4,910 million yen and 5,385 million yen are included as securities investment and other for the fiscal years ended March 31, 2019 and 2020, respectively.         *2 173,964 million yen and 188,426 million yen are included in foreign securities for which the fair value option has been elected and classified in level 2 for the fiscal years ended March 31, 2019 and 2020, respectively. In the consolidated balance sheets, 33,391 million yen and 34,502 million yen are included as marketable securities and 140,573 million yen and 153,924 million yen are included as securities investment and other for the fiscal years ended March 31, 2019 and 2020, respectively.         *3 185,195 million yen and 193,430 million yen are included in foreign securities for which the fair value option has been elected and classified in level 2 and level 3 for the fiscal years ended March 31, 2019 and 2020, respectively, and are included in the consolidated balance sheets as securities investments and other.         *4 Other investments include certain hybrid financial instruments and certain private equity investments.         *5 Derivative assets and liabilities are recognized and disclosed on a gross basis.                                       *6 Future insurance policy benefits and policyholders’ account in the life insurance business are those for which the fair value option has been elected.                                         7 Net gains of 85 million yen and net loss of 12,408 million yen arising from assets and liabilities for which the fair value option has been elected are included in financial services revenue and financial services expense in the consolidated statements of income for the fiscal years ended March 31, 2019 and 2020, respectively.                                       Transfers into level 1 were 1,769 million yen and 4,395 million yen for the fiscal years ended March 31, 2019 and 2020, respectively, as quoted prices for certain trading debt securities and equity securities became available in an active market. Transfers out of level 1 were 2,508 million yen and 3,216 million yen for the fiscal years ended March 31, 2019 and 2020, respectively, as quoted prices for certain trading debt securities were not available in an active market. The changes in fair value of level 3 assets and liabilities for the fiscal years ended March 31, 2019 and 2020 are as follows:                                                     Yen in millions     Fiscal year ended March 31, 2019     Assets     Liabilities     Debt securities         Future insurance policy benefits and Policyholders’ account     Available-for-sale securities         Japanese corporate bonds     Foreign corporate bonds     Securitized products     Other     Other investments   Beginning balance     —       27,878       83,614        —       9,104       —   Total realized and unrealized gains (losses):                                       Included in earnings *1     —       465       562        —       276       —   Included in other comprehensive income   (loss) *2     —       131       1         —       —       —   Purchases and Issuances     —       5,787       94,696        —       4       —   Sales     —       —       —        —       (6 )     —   Settlements     —       (10,435 )     (13,601 )      —       (2,460 )     —   Transfers into level 3 *3     —       20,863       5,284        —       —       —   Transfers out of level 3 *4     —       (21,985 )     (5,473 )      —       —       —                                                     Ending balance     —       22,704       165,083         —       6,918       —   Changes in unrealized gains (losses)   relating   to   instruments still held at   reporting date:                                                 Included in earnings *1     —       219       510         —       441       —                                                                                                     Yen in millions     Fiscal year ended March 31, 2020     Assets     Liabilities     Debt securities         Future insurance policy benefits and Policyholder s ’ account     Available-for-sale securities         Japanese corporate bonds     Foreign corporate bonds     Securitized products     Other     Other investments   Beginning balance     —       22,704       165,083        —       6,918       —   Acquisition of AEGON Sony Life Insurance Co.,   Ltd. and SA Reinsurance Ltd. *5     —       —       —        —       —       547,190   Total realized and unrealized gains (losses):                                       Included in earnings *1     —       311       (18,151 )      —       (500 )     12,500   Included   in   other   comprehensive   income   (loss) *2     —       (73 )     1        —       —       3,032   Purchases and Issuances     30       13,597       40,175       12,101       4,711       5,295   Sales     —       —       —        —       (9 )     —   Settlements     —       (20,867 )     (12,967 )      —       (1,878 )     (4,762 ) Transfers into level 3 *3     —       3,374       —        —       —       —   Transfers out of level 3 *4     —       (3,276 )     (2,301 )       —       —       —   Ending balance     30       15,770       171,840       12,101       9,242       532,191   Changes in unrealized gains (losses) relating to instruments still held at reporting date:                                       Included in earnings *1     —       (94 )     (16,507 )      —       (376 )     10,273                                       *1 Earning effects are included in financi a l services revenue and financial services expense in the consolidated statements of income.                                         *2 Unrealized gains (losses) are included in unrealized gains (losses) on securities, net for available-for-sale securities and included in debt valuation adjustments for future insurance policy benefits and policyholders’ account in the consolidated statements of comprehensive income.                                         *3 Certain corporate bonds and certain securitized products were transferred into level 3 because differences between the fair value determined by indicative quotes from dealers and the fair value determined by internally developed prices became significant and the observability of the inputs used decreased.                                         *4 Certain corporate bonds and certain securitized products were transferred out of level 3 because observable market data became available.                                         *5 Refer to Note 25                                       Level 3 assets include certain securitized products, certain private equity investments, and certain domestic and foreign corporate bonds for which quoted prices are not available in a market and where there is less transparency around inputs. In determining the fair value of such assets, Sony uses third-party information such as indicative quotes from dealers without adjustment. Level 3 liabilities include future insurance policy benefits and policyholders’ account in the life insurance business whose underlying figures are unobservable, and whose fair value is calculated in-house. For validating the fair values, Sony primarily uses internal models which include management judgment or estimation of assumptions that market participants would use in pricing the asset. (2) Assets and liabilities that are measured at fair value on a nonrecurring basis       Sony also has assets and liabilities that are required to be remeasured to fair value on a nonrecurring basis when certain circumstances occur. During the fiscal years ended March 31, 2019 and 2020, such remeasurements to fair value related primarily to the following:                                     During the fiscal year ended March 31, 2019     Estimated fair value     Amounts included  in earnings     Level 1     Level 2     Level 3   Assets:                         Long-lived assets impairments     —       —       4,389       (44,135 ) Goodwill impairment     —       —       0       (5,107 )                                                         (49,242 )                                             During the fiscal year ended March 31, 2020     Estimated fair value     Amounts included in earnings     Level 1     Level 2     Level 3   Assets:                         Remeasurement of retained investment in SRE       15,911       —       —       13,347   Long-lived assets impairments     —       —       8,155       (36,003 )                                                         (22,656 )                                         Long-lived assets impairments Sony recorded an impairment loss of 31,341 million yen, 19,172 million yen and 12,714 million yen for the fiscal years ended March 31, 2018, 2019 and 2020, respectively, included within the EP&S segment, related to long-lived assets in the smartphone business asset group. For the smartphone business asset group, the corresponding estimated future cash flows leading to the impairment charge reflected smartphone sales results and expectation of continued difficulty in the business environment. Sony recorded an impairment loss of 12,858 million yen for the fiscal year ended March 31, 2019, included within All Other, related to long-lived assets and goodwill in the storage media business asset group. As a result of conducting a strategic review of the business and evolving market trends, Sony reduced the corresponding estimated future cash flows of this business and the estimated ability to recover the entire carrying amount of the long-lived assets and goodwill within the period applicable to the impairment determination, resulting in an impairment charge for the fiscal year ended March 31, 2019. These measurements are classified as level 3 because significant unobservable inputs, such as the condition of the assets or projections of future cash flows, the timing of such cash flows and the discount rate reflecting the risk inherent in future cash flows, were considered in the fair value measurements. For the fiscal year ended March 31, 2018, a discount rate of 8.5% and projected revenue growth rates ranging from (8)% to 6% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2019, a discount rate of 8.5% and projected revenue growth rates ranging from (26)% to 24% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2020, a discount rate of 10.6% and projected revenue growth rates ranging from (10)% to 70% were used in the fair value measurements related to the long-lived assets for the smartphone business. For the fiscal year ended March 31, 2019, a discount rate of 8.9% and projected revenue growth rates ranging from (34)% to 21% were used in the fair value measurements related to the long-lived assets and goodwill for the storage media business. Except as described above, no other impairment losses were individually material for the fiscal year ended March 31, 2020. The other impairment losses were primarily related to the impairment losses in asset groups within Media Networks in the Pictures segment related to a review of the channel portfolio. Remeasurement of previously owned equity interest in EMI During the fiscal year ended March 31, 2019, Sony remeasured to fair value the previously owned equity interests in EMI in connection with EMI Music Publishing acquisition. The measurement is classified as level 3 because significant unobservable inputs, such as projections of future cash flows and market comparables of similar transactions and companies were considered in the fair value measurements. Refer to Note 25. Remeasurement of retained investment in SRE During the fiscal year ended March 31, 2020, Sony sold part of its shares in SRE and remeasured the remaining shares to fair value. This measurement is classified as level 1 because a quoted price for the shares of SRE is available on the Tokyo Stock Exchange. Refer to Note 5. Remeasurement of previously owned equity interest in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. During the fiscal year ended March 31, 2020, Sony remeasured to fair value the previously owned equity interests in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. (collectively, the “JVs”) in connection with acquisition of the JVs. The measurement is classified as level 3 because significant unobservable inputs, such as projections of future cash flows and market comparables of similar transactions and companies, were considered in the fair value measurements. AEGON Sony Life Insurance Co., Ltd. changed its name to “Sony Life With Insurance Co., Ltd.,” as of April 1, 2020. Refer to Note 25. (3) Financial instruments The estimated fair values by fair value hierarchy level of certain financial instruments that are not reported at fair value are summarized as follows:                                             Yen in millions     March 31, 2019     Estimated fair value     Carrying amount     Level 1     Level 2     Level 3     Total     Total   Assets:                               Housing loans in the banking business     —       1,861,384       —       1,861,384       1,685,504                                             Total assets     —       1,861,384       —       1,861,384       1,685,504                                             Liabilities:                               Long-term debt including the current portion     —       737,529       —       737,529       740,833   Investment contracts included in policyholders’ account in the life insurance business     —       877,157       —       877,157       816,903                                             Total liabilities     —       1,614,686       —       1,614,686       1,557,736                                                       Yen in millions     March 31, 2020     Estimated fair value     Carrying amount     Level 1     Level 2     Level 3     Total     Total   Assets:                               Housing loans in the banking business     —       2,161,432       —       2,161,432       1,927,054                                             Total assets     —       2,161,432       —       2,161,432       1,927,054                                             Liabilities:                               Long-term debt including the current portion     —       699,358       —       699,358       664,773   Investment contracts included in policyholders’ account in the life insurance business     —       969,464       —       969,464       885,690                                             Total liabilities     —       1,668,822       —       1,668,822       1,550,463                                                   The summary excludes cash and cash equivalents, call loans, time deposits, notes and accounts receivable, trade, call money, short-term borrowings, notes and accounts payable, trade and deposits from customers in the banking business because the carrying values of these financial instruments approximated their fair values due to their short-term nature. The summary also excludes held-to-maturity securities disclosed in Note 7. Cash and cash equivalents, call loans and call money are classified in level 1. Time deposits, short-term borrowings, deposits from customers in the banking business are classified in level 2. Held-to-maturity securities, included in marketable securities and securities investments and other in the consolidated balance sheets, primarily include debt securities with quoted prices that are traded less frequently than exchange-traded instruments, such as the majority of government bonds and corporate bonds and are substantially all classified in level 2. The fair values of housing loans in the banking business, included in securities investments and other in the consolidated balance sheets, were estimated based on the discounted future cash flows using interest rates reflecting London Interbank Offered Rate base yield curves with certain risk premiums. The fair values of long-term debt including the current portion and investment contracts included in policyholders’ account in the life insurance business were estimated based on either the market value or the discounted future cash flows using Sony’s current incremental borrowing rates for similar liabilities.

Investments in affiliated companies	12 Months Ended

Equity Method Investments and Joint Ventures [Abstract]
Investments in affiliated companies	5. Investments in affiliated companies The summarized combined financial information that is based on information provided by the equity investees including information for significant equity affiliates and the reconciliation of such information to the consolidated financial statements is shown below: Balance Sheets                     Yen in millions     March 31     2019     2020   Current assets     355,320       389,195   Noncurrent assets     608,626       164,852   Current liabilities     188,905       194,219   Noncurrent liabilities and noncontrolling interests     584,714       60,469   Percentage of ownership in equity investees     20%-50 %     20%-50 %                       Statements of Income                             Yen in millions     Fiscal year ended March 31     2018     2019     2020   Net revenues     468,933       390,457       387,678   Operating income     56,729       53,920       58,431   Net income attributable to controlling interests     27,301       5,539       34,916   Percentage of ownership in equity investees     20%-50 %     20%-50 %     20%-50 %                       On November 14, 2018, Sony Corporation of America, Sony’s wholly-owned subsidiary, completed the acquisition of the entirety of the approximately 60% equity interest held by the investor consortium led by the Mubadala Investment Company in DH Publishing, L.P. (“EMI”), which owned and managed EMI Music Publishing. As a result of this acquisition, EMI became a wholly-owned subsidiary of Sony as described in Note 25. The carrying value of Sony’s investment in M3, Inc. (“M3”)   exceeded its proportionate share in the underlying net assets of M3 by 56,140 million yen at March 31, 2020. The excess is substantially attributable to the remeasurement to fair value of the remaining shares of M3, and allocated to identifiable tangible and intangible assets. The intang ible assets relate primarily to M3’s medical web-portal. The unassigned residual value of the excess is recognized as goodwill as a component of the investment balance. The amounts allocated to intangible assets are amortized net of the related tax effects to equity in net income (loss) of affiliated companies over their respective estimated useful lives, principally 10 years, using the straight-line method. With the exception of M3 as described above, there was no significant difference between Sony’s proportionate share in the underlying net assets of the investees and the carrying value of investments in affiliated companies at March 31, 2019 and 2020. On December 19, 2019, SRE Holdings Corporation (“SRE”), Sony’s consolidated subsidiary, became a publicly listed company on the Tokyo Stock Exchange Mothers market (the “Listing”). Upon the Listing, Sony sold a portion of its shares of SRE, and shares issued by SRE were publicly offered (collectively, the “Sale”). Sony’s ownership of SRE’s total shares, which was 56.3% before the Sale, has decreased to 44.5% after the Sale. As a result, SRE has become an affiliate accounted for under the equity method of Sony. In connection with the Sale, Sony recorded a gain of 17,266 million yen, which consisted of both a remeasurement gain based on fair value for the shares Sony continues to hold after the Sale, and a realized gain for the sold shares, in other operating (income) loss, net in the consolidated statements of income for the fiscal year ended March 31, 2020. On January 29, 2020, Sony Life Insurance Co., Ltd.(“Sony Life”), Sony’s consolidated subsidiary, completed the acquisition of the entirety of 50% equity interest held by AEGON International B.V. in AEGON Sony Life Insurance Co., Ltd. and SA Reinsurance Ltd. (collectively, the “JVs”). As a result of this acquisition, the JVs became consolidated subsidiaries of Sony as described in Note 25. AEGON Sony Life Insurance Co., Ltd. has changed its name to “Sony Life With Insurance Co., Ltd.,” as of   April 1, 2020.   Several affiliated companies are listed on the Tokyo Stock Exchange and Sony’s investments in these companies have an aggregate carrying value and fair value of 141,508 million yen and 756,073 million yen, respectively, as of March 31, 2020. The number of affiliated companies accounted for under the equity method as of March 31, 2019 and 2020 were 133 and 140, respectively. Account balances and transactions with affiliated companies accounted for under the equity method are presented below. There are no other material transactions or account balances with any other related parties.                     Yen in millions     March 31     2019     2020   Accounts receivable, trade     12,404       12,030   Other receivables     134       1,589   Other current assets     33       9,757   Accounts payable, trade     1,087       1,497   Short-term borrowings     29,744       31,557   Finance lease liabilities and other*     20,265       34,564   Operating lease liabilities     —       2,393                                   * Finance lease liabilities and other were represented as Capital lease obligations as of the fiscal year ended March 31, 2019.                                                           Yen in millions     Fiscal year ended March 31     2018     2019     2020   Sales     45,415       41,437       35,951   Purchases     3,180       5,584       3,479                                 Sony entered into sale and leaseback transactions regarding certain machinery and equipment with SFI Leasing Company, Limited (“SFIL”), a leasing company in Japan, in the fiscal years ended March 31, 2018   and 2019. SFIL is accounted for under the equity method and is 34% owned by Sony. MITSUI-SOKO Supply Chain Solutions, Inc. is accounted for under the equity method and is 34% owned by Sony as a result of the sale of the logistics business on April 1, 2015. As of the fiscal years ended March 31, 2019 and 2020, account balances with MITSUI-SOKO Supply Chain Solutions, Inc. and its subsidiaries were 3,435 million yen and 1,181 million yen, respectively, which are mainly included in accrued expenses. For the fiscal years ended March 31, 2019 and 2020, transactions were 10,606 million yen and 6,069 million yen, respectively, which are mainly included in general and administrative expenses. Dividends from affiliated companies accounted for under the equity method for the fiscal years ended March 31, 2018, 2019 and 2020 were 5,613 million yen, 4,948 million yen and 4,523 million yen, respectively.

Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning January 1, 2018 and the transition of U.S. international taxation from a worldwide tax system to a modified territorial system, with a one-time mandatory transition tax on previously deferred foreign earnings of U.S. subsidiaries. In addition to lowering the statutory corporate tax rate from 35% to 21%, the U.S. Tax Reform Act also eliminated certain deductions, included new restrictions on the deduction for interest, introduced a new tax regime called the Base Erosion Anti-Abuse Tax or “BEAT”, and changed how foreign earnings of the U.S. group are subject to tax. The U.S. Tax Reform Act also enhanced and extended the option to claim accelerated depreciation and amortization deductions by allowing full expensing of qualified property, including film costs, through 2022. The U.S. Tax Reform Act also provided for beneficial treatment of certain income derived by a U.S. entity from outside the United States (referred to as Foreign Derived Intangible Income or “FDII”). The BEAT creates a minimum tax on multinational corporations by requiring companies subject to the BEAT to pay the greater of their regular tax liability (less certain credits, including foreign tax credits) or 10% for taxable years beginning in 2019 (6.25% for the  fiscal year ended March 31. 2019) of a modified tax base which adds back certain related party payments. The BEAT comparison to regular tax must be done each year if the taxpayer’s “base erosion” related party payments exceed 3% of total deductions on its U.S. tax return. The U . S . Treasury Department issued regulations which allow taxpayers to elect to forego deductions in order to stay below the 3% threshold. Sony initially expected to exceed the 3% threshold for the fiscal year ended March 31, 2019, but upon further detailed analysis at the time of the tax return filing, determined that it would be below the 3% threshold and therefore could use foreign tax credits to offset its regular tax liability. Sony believes it will be below the 3% threshold for the fiscal year ended March 31, 2020, and if not, would be able to avail itself of the election in the regulations that allows it to forego deductions to come under the threshold. Accordingly, Sony has provided for its taxes assuming the U . S . regular tax liability is offset by tax credits. Sony is required to determine if it is subject to the BEAT on an annual basis, to account for th e BEAT as a period cost and to record deferred taxes at the regular statutory rate. Accordingly, Sony has recorded its U.S. deferred tax assets and liabilities at 21%. Sony provides a valuation allowance for its deferred tax assets, which includes net operating losses, temporary differences and tax credits, when it is more likely than not that some portion, or all, of its deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income in the relevant tax jurisdiction. As of December 31, 2018, SAHI and its U.S. consolidated tax filing group has continued its profitable trend, primarily as a result of the G&NS segment and the Music segment. Based on an assessment of the available positive and negative evidence, in the quarter ended December 31, 2018, Sony reversed the valuation allowances established against a significant portion of the deferred tax assets in the United States, primarily for net operating losses, temporary differences and certain tax credits, and recorded a tax benefit of 154,201 million yen. The significant components of deferred tax assets and liabilities are as follows:                     Yen in millions     March 31     2019     2020   Deferred tax assets:             Operating loss carryforwards for tax purposes     413,494       348,714   Accrued pension and severance costs     103,652       77,559   Amortization including film costs     86,196       65,349   Lease liability     —       100,720   Warranty reserves and accrued expenses     108,515       116,234   Future insurance policy benefits     36,683       42,056   Inventory     19,716       15,512   Depreciation     34,638       39,085   Tax credit carryforwards     117,471       94,900   Loss on equity securities     —       11,815   Reserve for doubtful accounts     9,136       9,090   Impairment of investments     12,278       6,029   Deferred revenue     19,081       24,420   Other     169,897       122,591                     Gross deferred tax assets     1,130,757       1,074,074   Less: Valuation allowance     (723,114 )     (608,243 )                   Total deferred tax assets     407,643       465,831                     Deferred tax liabilities:             Insurance acquisition costs     (169,244 )     (170,868 ) Future insurance policy benefits     (181,052 )     (193,315 ) Unbilled accounts receivable in the Pictures segment     (44,842 )     (26,214 ) Right-of-use assets     —       (96,970 ) Unrealized gains on securities     (75,573 )     (92,791 ) Gain on equity securities     (33,082 )     —   Intangible assets acquired through stock exchange offerings     (23,949 )     (23,949 ) Intangible assets derived from EMI Music Publishing acquisition     (93,979 )     (89,909 ) Undistributed earnings of foreign subsidiaries and corporate joint ventures     (15,758 )     (25,359 ) Investment in M3     (37,007 )     (38,303 ) Other     (62,092 )     (47,319 )                   Gross deferred tax liabilities     (736,578 )     (804,997 )                   Net deferred tax liabilities     (328,935 )     (339,166 )                               Based on the weight of the available positive and negative evidence, for the fiscal year ended March 31, 2020, Sony continued to maintain valuation allowances against the deferred tax assets at Sony Corporation and its national tax filing group in Japan, as well as at Sony Mobile Communications in Sweden, Sony Europe B.V. in the United Kingdom, certain subsidiaries in Brazil, and certain subsidiaries in other tax jurisdictions. Valuation allowances also continue to be established on the remaining U.S. deferred tax assets, primarily foreign tax credits and certain research and development credits. Sony Corporation and its national tax filing group in Japan established a valuation allowance   of 274,761  million yen relating to national  tax and 125,465 million yen relating to local tax. For the deferred tax assets related to national tax in Sony Corporation and its national tax filing group in Japan, the valuation allowance is still established except for the amounts expected to be offset with taxable temporary differences as of March 31, 2020. Due to the uncertainty of the forecast of future income impacted by the spread of COVID-19 from early 2020, the valuation allowance established against the net deferred tax assets that are attributable to Sony Corporation and its national tax filing group in Japan was not reversed, even partially, in the fiscal year ended March 31, 2020 despite several years of profitability. The net changes in the total valuation allowance were decreases of 152,129 million yen, 176,721 million yen and 114,871 million yen for the fiscal years ended March 31, 2018, 2019 and 2020, respectively. The decrease in the valuation allowances during the fiscal year ended March 31, 2018 was primarily due to the use of net operating loss carryforwards and other deferred tax assets for both the national tax filing group in Japan and the consolidated tax filing group in the United States. The U.S. deferred tax assets were also reduced as a result of the reduction in the tax rate under the U.S. Tax Reform Act which had a corresponding reduction of the valuation allowance on those assets. In addition, valuation allowances were reversed in several jurisdictions, including France and Canada, as a result of sustained profitability. The decrease in the valuation allowances during the fiscal year ended March 31, 2019 was due to the reversal of the valuation allowances on significant deferred tax assets in SAHI and its U.S. consolidated tax filing group and the use of net operating loss carryforwards and other deferred tax assets in the national tax filing group in Japan and other jurisdictions. The decrease in the valuation allowances during the fiscal year ended March 31, 2020 was due to the use of net operating loss carryforwards and other deferred tax assets in the national tax filing group in Japan and the use of foreign tax credits and certain research and development credits in the consolidated tax filing group in the United States. At March 31, 2020, 16,312 million yen of deferred income taxes have not been provided on undistributed earnings of certain foreign subsidiaries and corporate joint ventures not expected to be remitted in the foreseeable future totaling 1,019,525 million yen. In addition, deferred income taxes have not been provided on the gain on the book/tax basis difference in subsidiaries, including a gain of 61,544 million yen on a subsidiary’s sale of stock arising from the issuance of common stock of Sony Music Entertainment (Japan) Inc. in a public offering to third parties in November 1991 and the remeasurement gain for the equity interest in EMI (Refer to Note 25). Sony does not anticipate any significant tax consequences on the possible future disposition of these investments based on its tax planning strategies. At March 31, 2020, Sony had net operating loss carryforwards, the tax effect of which totaled 348,714 million yen, which may be available as an offset against future taxable income on tax returns to be filed in various tax jurisdictions. With the exception of 96,890 million yen with no expiration period, substantially all of the total net operating loss carryforwards expire at various dates between the fiscal years ending March 31, 2021 and 2024. Tax credit carryforwards at March 31, 2020 amounted to 94,900 million yen. With the exception of 15,059 million yen with no expiration period, substantially all of the total available tax credit carryforwards expire at various dates between the fiscal years ending March 31, 2021 and 2030. A reconciliation of the beginning and ending gross amounts of unrecognized tax benefits is as follows:                             Yen in millions     March 31     2018     2019     2020   Balance at beginning of the fiscal year     119,529       95,425       50,577   Reductions for tax positions of prior years     (8,809 )     (31,396 )     (331 ) Additions for tax positions of prior years     4,681       3,094       162   Additions based on tax positions related to the current year     5,740       2,594       8,074   Settlements     (21,893 )     (4,235 )     (13,240 ) Lapse in statute of limitations     (3,469 )     (14,824 )     (1,251 ) Foreign currency translation adjustments     (354 )     (81 )     (2,723 )                           Balance at end of the fiscal year     95,425       50,577       41,268                             Total net amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate     39,308       35,004       29,539         The major changes in the total gross amount of unrecognized tax benefit balances relate to transfer pricing adjustments, including as a result of the Bilateral Advance Pricing Agreements (“APAs”) and competent authority requests filed for certain subsidiaries in the G&NS, EP&S and I&SS segments and All Other, with respect to the intercompany cross-border transactions. The APAs include agreements between Sony and two taxing authorities under the authority of the mutual agreement procedure specified in income tax treaties. Sony reviews its estimated tax expense based on the progress made in these procedures, and the progress of transfer pricing audits generally, and makes adjustments to its estimates as necessary. In addition, the APAs are government to government negotiations, and therefore it is possible that the final outcomes of the agreements may differ from Sony’s current assessment of the more-likely-than-not outcomes of such agreements. During the fiscal year ended March 31, 2018, Sony recorded 1,053 million yen of interest expense and 876 million yen of penalties. At March 31, 2018, Sony had recorded liabilities of 10,788 million yen and 4,637 million yen for the payments of interest and penalties, respectively. During the fiscal year ended March 31, 2019, Sony reversed 1,479 million yen of interest expense and recorded 218 million yen of penalties. At March 31, 2019, Sony had recorded liabilities of 9,309 million yen and 4,855 million yen for the payments of interest and penalties, respectively. During the fiscal year ended March 31, 2020, Sony re versed  1,276 million yen of interest expense and re corded  117 million yen of penalties. At March 31, 2020, Sony had recorded liabilities of 8,033 million yen and 4,971 million yen for the payments of interest and penalties, respectively. Sony operates in multiple jurisdictions throughout the world, and its tax returns are periodically audited by Japanese and foreign taxing authorities. As a result of audit settlements, the conclusion of current examinations, the expiration of the statute of limitations in several jurisdictions and other reevaluations of Sony’s tax positions, it is expected that the amount of unrecognized tax benefits will change in the next twelve months. Accordingly, Sony believes it is reasonably possible that its existing unrecognized tax benefits may be reduced by an amount up to 1,791 million yen within the next twelve months. Sony remains subject to examinations by Japanese taxing authorities for tax years from 2010 through 2019, and by the U.S. tax authorities for tax years from 2016 through 2019 and other material foreign taxing authorities for tax years from 2006 through 2019.

Potential shares related to stock acquisition rights were excluded as anti-dilutive for the fiscal years ended March 31, 2018, 2019 and 2020 when the exercise price for those shares was in excess of the average market value of Sony’s common stock for those fiscal years. The zero coupon convertible bonds issued in July 2015 were included in the diluted EPS calculation under the if-converted method beginning upon issuance.

Collaborative arrangements	12 Months Ended
	Mar. 31, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Collaborative arrangements	27. Collaborative arrangements     Sony’s collaborative arrangements primarily relate to arrangements entered into, through subsidiaries in the Pictures segment, with one or more active participants to jointly finance, produce and/or distribute motion pictures or television programming under which both the subsidiaries and the other active participants share in the risks and rewards of ownership. These arrangements are referred to as co-production and distribution arrangements. Sony typically records an asset for only the portion of the motion pictures or television programming it owns and finances. Sony and the other participants typically distribute the product in different media or markets. Revenues earned and expenses incurred for the media or markets in which Sony distributes the product are typically recorded on a gross basis. Sony typically does not record revenues earned and expenses incurred when the other participants distribute the product. Sony and the other participants typically share in the profits from the distribution of the product in all media or markets. For motion pictures, if Sony is a net receiver of (1) Sony’s share of the profits from the media or markets distributed by the other participants less (2) the other participants’ share of the profits from the media or markets distributed by Sony then the net amount is recorded as net sales. If Sony is a net payer then the net amount is recorded in cost of sales. For television programming, Sony records its share of the profits from the media or markets distributed by the other participants as sales, and the other participants’ share of the profits from the media or markets distributed by Sony as cost of sales. For the fiscal years ended March 31, 2018, 2019 and 2020, 49,547 million yen, 42,343 million yen and 33,921 million yen, respectively, were recorded as net sales for amounts due from the other participants and 24,280 million yen, 22,702 million yen and 21,052 million yen, respectively, were recorded as cost of sales for amounts owed to the other participants in these collaborative arrangements.

Banking and Thrift [Abstract]
Housing loans and deposits from customers in the banking business	12. Housing loans and deposits from customers in the banking business           (1) Housing loans in the banking business           Sony acquires and holds certain financial receivables in the normal course of business. The majority of financing receivables held by Sony consists of housing loans in the banking business and no other significant financial receivables exist. A subsidiary in the banking business monitors the credit quality of housing loans based on the classification set by the financial conditions and the past due status of individual obligors. Past due status is monitored on a daily basis and the aforementioned classification is reviewed on a quarterly basis. The allowance for the credit losses is established based on the aforementioned classifications and the evaluation of collateral. The amount of housing loans in the banking business and the corresponding allowance for credit losses as of March 31, 2019 were 1,685,504 million yen and 829 million yen, respectively, and as of March 31, 2020 were 1,927,054 million yen and 780 million yen, respectively. During the fiscal years ended March 31, 2019 and 2020, charge-offs on housing loans in the banking business and changes in the allowance for credit losses were not significant. The balance of housing loans placed on nonaccrual status or past due status were not significant as of March 31, 2019 and 2020. (2) Deposits from customers in the banking business           All deposits from customers in the banking business within the Financial Services segment are interest bearing deposits. At March 31, 2019 and 2020, the balances of time deposits issued in amounts of 10 million yen or more were 292,968 million yen and 306,449 million yen, respectively. These amounts have been classified as current liabilities mainly due to the ability of the customers to make withdrawals prior to maturity. At March 31, 2020, aggregate amounts of annual maturities of time deposits with a remaining term of more than one year are as follows:           Fiscal year ending March 31   Yen in millions   2022     39,145   2023     16,102   2024     10,513   2025     3,238   2026     2,190   Later fiscal years     12,823             Total     84,011

- Definition This element represents the weighted average total number of shares issued throughout the period including the first (beginning balance outstanding) and last (ending balance outstanding) day of the period before considering any reductions (for instance, shares held in treasury) to arrive at the weighted average number of shares outstanding. Weighted average relates to the portion of time within a reporting period that common shares have been issued and outstanding to the total time in that period. Such concept is used in determining the weighted average number of shares outstanding for purposes of calculating earnings per share (basic). + References Reference 1: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 260 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6371337&loc=d3e3550-109257 Reference 2: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 260 -SubTopic 10 -Section 45 -Paragraph 10 -URI http://asc.fasb.org/extlink&oid=117326831&loc=d3e1448-109256 Reference 3: http://fasb.org/us-gaap/role/ref/legacyRef -Publisher FASB -Name Accounting Standards Codification -Topic 260 -SubTopic 10 -Section 45 -Paragraph 13 -URI http://asc.fasb.org/extlink&oid=117326831&loc=d3e2646-109256 + Details Name: us-gaap_WeightedAverageNumberOfSharesIssuedBasic Namespace Prefix: us-gaap_ Data Type: xbrli:sharesItemType Balance Type: na Period Type: duration
