The forward-looking statements are subject to various risks and uncertainties. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “anticipate,” “believe,” “considering,” “depends,” “estimate,” “expect,” “intend,” “plan,” “planning,” “planned,” “project” and similar expressions, or that certain events, actions or results “may,” “might,” “should” or “could” occur, be taken or be achieved.

Forward-looking statements in this annual report include, but are not limited to, statements about the following:

 

   

our ability to anticipate and respond to various competitive factors affecting the telecommunications industry, including new services that may be introduced, changes in consumer preferences, economic conditions and discount pricing strategies by competitors;

our efforts to make significant investments to build, develop and broaden our businesses, including developing our next-generation growth businesses in media, security, commerce, mobility, IoT solutions and other innovative products and services offered through our platform services, including AI solutions, and to create synergies among our businesses, including through the adaptation of AI technology;

 

   

our ability to comply with governmental rules and regulations, including the regulations of the Government related to telecommunications providers, the Mobile Device Distribution Improvement Act (“MDDIA”), rules related to our status as a “market-dominating business entity” under the Korean Monopoly Regulation and Fair Trade Act (the “Fair Trade Act”) and the effectiveness of steps we have taken to comply with such regulations;

We caution you that reliance on any forward-looking statement involves risks and uncertainties, and that although we believe that the assumptions on which our forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and, as a result, the forward-looking statements based on those assumptions could be incorrect.

Selected Financial Data

You should read the selected consolidated financial and operating data below in conjunction with the consolidated financial statements and the related notes included elsewhere in this annual report. The selected consolidated financial data set forth below as of and for each of the five years ended December 31, 2020 have been derived from our audited consolidated financial statements and related notes thereto, which have been prepared in accordance with IFRS as issued by the IASB.

In addition to preparing consolidated financial statements in accordance with IFRS as issued by the IASB included in this annual report, we also prepare financial statements in accordance with Korean International Financial Reporting Standards (“K-IFRS”) as adopted by the Korean Accounting Standards Board (the “KASB”), which we are required to file with the Financial Services Commission of Korea (the “FSC”) and the Korea Exchange Inc. (the “Korea Exchange”) under the Financial Investment Services and Capital Markets Act (the “FSCMA”). English translations of such financial statements are furnished to the U.S. Securities and Exchange Commission (the “SEC”) on Form 6-K. K-IFRS requires operating profit, which is calculated as operating revenue less operating expense, to be separately presented on the consolidated statement of income. Operating expense represents expenses incurred in our main operating activities and includes cost of goods sold and selling, general and administrative expenses. The presentation of operating profit in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report differs from the presentation of operating profit in the consolidated statements of income prepared in accordance with K-IFRS for the corresponding periods in certain respects. For additional information, see “Item 5.A. Operating Results — Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS.”

Risk Factors

Risks Relating to Our Business

Competition may reduce our market share and harm our results of operations and financial condition.

We face substantial competition across all our businesses, including our wireless telecommunications business. We expect competition to intensify as a result of the development of new technologies, products and services. We expect that such trends will continue to put downward pressure on the rates we can charge our subscribers.

Historically, there has been considerable consolidation in the telecommunications industry, resulting in the current competitive landscape comprising three mobile and fixed network operators in the Korean market, us, KT Corporation (“KT”) and LG Uplus Corp. (“LG U+”). Each of our competitors has substantial financial, technical, marketing and other resources to respond to our business offerings. The collective market share of KT and LG U+ amounts to approximately 54.9%, in terms of number of wireless subscribers (including an aggregate of 9.8% attributable to MVNOs that lease KT’s and LG U+’s respective networks), as of December 31, 2020.

Our competitors for subscriber activations include MVNOs, including MVNOs that lease our networks. MVNOs generally provide rate plans that are relatively cheaper than similar rate plans of the wireless network providers from which they lease their networks, including us. In addition, other companies may enter the wireless network services market. While new entries into such market have historically required obtaining requisite licenses from the MSIT, pursuant to an amendment to the Telecommunications Business Act that went into effect in June 2019, companies meeting certain regulatory criteria may become a network service provider by registering with the MSIT without a separate license requirement. Although such amendment has not yet resulted in any new entries into the Korean wireless network services market, it may have the effect of encouraging new entries in the future.

We believe that an increase in market share of MVNOs and the entrance of new mobile network operators, if any, in the wireless telecommunications market may further increase competition in the telecommunications sector,

as well as cause downward price pressure on the fees we charge for our services, which, in turn, may have a material adverse effect on our results of operations, financial position and cash flows.

Our fixed-line telephone service competes with KT and LG U+, as well as other providers of voice over Internet protocol (“VoIP”) services. As of December 31, 2020, our market share of the fixed-line telephone and VoIP service market was 15.8% (including the services provided by SK Broadband Co., Ltd. (“SK Broadband”) and SK Telink Co., Ltd. (“SK Telink”)) in terms of number of subscribers compared to KT with 56.8% and LG U+ with 19.1%. In addition, our broadband Internet access, Internet protocol TV (“IPTV”) and cable TV services provided through SK Broadband compete with other providers of such services, including KT, LG U+ and cable companies. Furthermore, our IPTV and cable TV services are facing an increasing level of competition from global operators of online video streaming platforms, such as YouTube, Amazon Video and Netflix, and the video services offered by leading domestic online and mobile search and communications platforms including NAVER and Kakao, as such services continue to become increasingly popular to serve as a substitute to traditional television programming. As of December 31, 2020, our market share of the broadband Internet market was 29.0% in terms of number of subscribers compared to KT with 41.1% and LG U+ with 20.3%. As of December 31, 2020, our market share of the pay TV market (which includes IPTV, cable TV and satellite TV) was 24.4% compared to KT with 32.2% (including its IPTV and satellite TV services) and LG U+ with 25.0% (including its IPTV and cable TV services), and the collective market share of other pay TV providers was 18.4%.

Recently, the Korean fixed-line telecommunications industry has been going through significant consolidation involving major pay television service providers. In April 2020, we completed the merger of Tbroad Co., Ltd., a former leading cable television and other fixed-line telecommunication services provider in Korea, and two of its subsidiaries, Tbroad Dongdaemun Broadcasting Co., Ltd. and Korea Digital Cable Media Center Co. Ltd. (collectively, “Tbroad”), with and into SK Broadband. As a result of the merger and the issuance of SK Broadband’s shares to the former shareholders of Tbroad with an aggregate fair value of Won 862.1 billion as of April 30, 2020, we own approximately 74.3% of SK Broadband’s total outstanding shares as of December 31, 2020. In the same month, SK Telecom acquired a 55.0% equity interest in Broadband Nowon Co., Ltd. (formerly known as Tbroad Nowon Broadcasting Co., Ltd.), another subsidiary of Tbroad Co., Ltd., for a purchase price of Won 10.4 billion in cash. As a result of such transactions (the “Tbroad Merger”), we have become the third-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. In December 2019, LG U+ acquired a majority equity stake in CJ Hello Co., Ltd. and changed the acquired company’s name to LG HelloVision Co., Ltd. (“LG HelloVision”) to collectively become the second-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. Such transactions, as well as further consolidation in the fixed-line telecommunications industry, may result in increased competition, as the entities emerging from such consolidation and other remaining players in the industry may actively pursue expanding or protecting their respective market shares.

Furthermore, the Government has historically enforced regulations on cable TV and IPTV service providers that prohibited them from having a market share of more than one-third of the total number of subscribers in the relevant pay TV market on each of their respective platforms. In June 2015, the Government amended the regulation to impose the same limit on the market share of the entire pay TV market, including satellite TV service providers as well. Such amended regulation, however, expired in June 2018. There are bills currently pending in the National Assembly to abolish the previous market share regulations on cable TV and IPTV service providers. It is uncertain whether such bills will be passed.

Continued competition from other wireless and fixed-line service providers has also resulted in, and may continue to result in, a substantial level of deactivations among our subscribers. Subscriber deactivations, or churn, may significantly harm our business and results of operations. In 2020, the monthly churn rate in our wireless telecommunications business ranged from 1.1% to 1.4%, with an average monthly churn rate of 1.2%, which remained unchanged from 2019. Intensification of competition in the future may cause our churn rates to increase, which in turn may cause us to increase our marketing expenses as a percentage of sales to attract and retain subscribers.

Our physical security business competes with other large physical security service providers, including S-1 Corporation (“S-1”) and KT Telecop Co., Ltd. (“KT Telecop”). As of December 31, 2020, our market share of the physical security services market was 34% in terms of the aggregate revenue of these three companies, compared to

 

8


Table of Contents

S-1 with 55% and KT Telecop with 11%. Our information security services compete with other providers of similar products and services, such as Ahnlab, Inc., SECUi Corp. and Igloo Security, Inc.

With respect to the e-commerce business operated by Eleven Street Co., Ltd. (“Eleven Street”), 11st, our marketplace business, faces intense competition from various e-commerce providers, including online open marketplaces and social commerce operators such as Coupang, Gmarket, Auction and Interpark. We also face competition from leading online and mobile search and communication platform companies with e-commerce operations, including NAVER and Kakao, as well as traditional retailers with online and mobile shopping portals such as SSG.com and Lotte.com, home shopping providers with online and mobile shopping portals such as CJ Mall by CJ O Shopping, GS Shop by GS Homeshopping and Hyundai Hmall by Hyundai Homeshopping, and various online marketplaces for specific consumer segments or product groups. Our television shopping (“T-commerce”) business, SK stoa, primarily competes with other home shopping providers such as those listed above, as well as with various e-commerce providers and traditional retailers. The industries in which 11st and SK stoa compete are evolving rapidly and are intensely competitive, and we face a broad array of competitors domestically and increasingly, internationally.

Our ability to compete successfully in all of the businesses in which we operate will depend on our ability to anticipate and respond to various competitive factors affecting the respective industries, including new services that may be introduced, changes in consumer preferences, economic conditions and discount pricing strategies by competitors.

Inability to successfully implement or adapt our network and technology to meet the continuing technological advancements affecting the wireless telecommunications industry will likely have a material adverse effect on our financial condition, results of operation, cash flows and business.

The telecommunications industry has been characterized by continual improvement and advances in technology, and this trend is expected to continue. We and our competitors have continually implemented technology upgrades from our basic code division multiple access (“CDMA”) network to our wideband code division multiple access (“WCDMA”) network, and subsequently to LTE and 5G technologies. Our business could be harmed if we fail to implement, or adapt to, future technological advancements in the telecommunications sector in a timely manner, such as the continued implementation of 5G technology. We launched wireless service plans using the 5G network in April 2019 following the commencement of sales of the first 5G-compatible smartphones, and we are in the process of expanding our 5G network coverage, focusing on major commercial districts and other densely-populated areas in the Seoul metropolitan area and other cities. KT and LG U+ have also rolled out their respective 5G wireless service plans in April 2019. The more successful operation of a 5G network or development of improved 5G technology by a competitor, including better market acceptance of a competitor’s 5G services, could materially and adversely affect our existing wireless telecommunications businesses as well as the returns on future investments we may make in our 5G network or our other businesses.

In addition to introducing new technologies and offerings, we must phase out outdated and unprofitable technologies and services. For example, as of January 2019, we discontinued our wireless broadband Internet access (“WiBro”) services, and we also terminated our second generation CDMA wireless services in July 2020. If we are unable to do so on a cost-effective basis, our results of operations could be adversely affected.

Implementation of new wireless technology and enhancement of existing wireless technology have required, and may continue to require, significant capital and other expenditures, which we may not recoup.

We have made, and intend to continue to make, capital investments to develop, launch and enhance our wireless service. In 2020, 2019 and 2018, we spent Won 1,878.6 billion, 2,514.3 billion and Won 1,735.6 billion, respectively, in capital expenditures to build and enhance our wireless networks. Our continued implementation and expansion of 5G services, which use a higher frequency spectrum than our LTE services, will require additional cell sites and other infrastructure, which may result in an increase in our capital expenditures in the future. We also plan to make further capital investments related to our wireless services in the future, including services that can potentially leverage our 5G network. In addition, we plan to continue maintaining our LTE network, which we expect will continue to be used broadly by our subscriber base during the near future, as we and our competitors

Table of Contents

continue to build up 5G networks and services and wireless service users gradually migrate to the 5G network over time. Our wireless technology-related investment plans are subject to change, and will depend, in part, on market demand for 5G and LTE services, the competitive landscape for provision of such services and the development of competing technologies. There may not be sufficient demand for services based on our latest wireless technologies, as a result of competition or otherwise, to permit us to recoup or profit from our wireless technology-related capital investments.

Our businesses are subject to extensive Government regulation and any change in Government policy relating to the telecommunications industry could have a material adverse effect on our results of operations, financial condition and cash flows.

Most of our businesses are subject to extensive governmental supervision and regulation.

Rate Regulation. The Government has periodically reviewed the rates charged by wireless telecommunications service providers and has, from time to time, released public policy guidelines or suggested rate reductions. Although these guidelines or suggestions were not binding, we have implemented some rate reductions in response to them. For example, under the MDDIA, wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving subsidies. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively. See “Item 4.B. Business Overview — Law and Regulation — Rate Regulation” and “Item 5.A. Operating Results — Overview — Rate Regulations.” Such discounts have contributed to a decrease in the monthly revenue per subscriber of our wireless telecommunications services. See “Item 5.A. Operating Results — Overview — Decrease in Monthly Revenue per Subscriber.” The Government may suggest other rate reductions in the future, including more affordable subscription plans for 5G wireless services, and any further rate reductions we make in response to such suggestion may adversely affect our results of operations.

Technology Standards. The Government also plays an active role in setting the timetable and quality standards for the adoption and implementation of new technologies to be used by telecommunications operators in Korea. For example, the Government provided such guidance in connection with the introduction of LTE and 5G technologies in the past. The Government may provide similar guidance or recommendations in connection with the adoption and implementation of technologies to be used in future telecommunications services, and it is possible that adherence to such guidance or recommendations promoted by the Government in the future may not provide the best commercial returns for us.

Frequency Allocation. The Government sets the policies regarding the use of frequencies and allocates the spectrum of frequencies used for wireless telecommunications. See “Item 4.B. Business Overview — Law and Regulation — Frequency Allocation.” The reallocation of the spectrum to our existing competitors could increase competition among wireless telecommunications service providers, which may have an adverse effect on our business.

MVNOs. Pursuant to the Telecommunications Business Act, certain wireless telecommunications service providers designated by the MSIT, which included only us, were required to lease their networks or allow use of their networks (collectively, a “wholesale lease”) to other network service providers, such as an MVNO, that have requested such a wholesale lease in order to provide their own services using the leased networks until September 2022. Currently, 14 MVNOs provide wireless telecommunications services using the networks leased from us. We believe that leasing a portion of our bandwidth capacity to an MVNO impairs our ability to use our bandwidth in ways that would generate maximum revenues and strengthens our MVNO competitors by granting them access and lowering their costs to enter into and operate in our markets. Accordingly, our profitability has and may continue to be adversely affected.

Interconnection. Our wireless telecommunications services depend, in part, on our interconnection arrangements with domestic and international fixed-line and other wireless networks. Our interconnection

 

10


Table of Contents

arrangements, including the interconnection rates we pay and interconnection rates we charge, affect our revenues and operating results. The MSIT determines the basic framework for interconnection arrangements, including policies relating to interconnection rates in Korea. The KCC, which determined such basic framework under the previous Government, changed the basic framework for interconnection arrangements several times. We cannot assure you that we will not be adversely affected by the MSIT’s interconnection policies and future changes to such policies. See “Item 4.B. Business Overview — Interconnection — Domestic Calls.”

Regulatory Action. The MSIT may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the KCC may levy a monetary penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years. For information about the penalties imposed on us for violating Governmental regulations, see “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — KCC Proceedings.” Such penalties, which may include the revocation of cellular licenses, suspension of business or imposition of monetary penalties by the KCC, could have a material adverse effect on our business. We believe we are currently in compliance with the material terms of all our cellular licenses.

We are subject to additional regulations as a result of our dominant market position in the wireless telecommunications sector, which could harm our ability to compete effectively.

The Government endeavors to promote competition in the Korean telecommunications markets through measures designed to prevent a dominant service provider from exercising its market power and deterring the emergence and development of viable competitors. We have been designated by the MSIT as the “dominant network service provider” in respect of our wireless telecommunications business. As such, we are subject to additional regulations to which certain of our competitors are not subject. For example, beginning in December 2020, the MSIT has fifteen days to object to any new rates and terms of service reported by us, compared to the prior regulations that required us to obtain prior approval from the MSIT to raise our existing rates or introduce new rates. See “Item 4.B. Business Overview — Law and Regulation — Rate Regulation.” The MSIT could also require us to charge higher usage rates than our competitors for future services or to take certain actions earlier than our competitors, as when the KCC required us to introduce number portability earlier than our competitors, KT and LG U+.

We also qualify as a “market-dominating business entity” under the Fair Trade Act, which subjects us to additional regulations and we are prohibited from engaging in any act of abusing our position as a market-dominating entity. See “Item 4.B. Business Overview — Law and Regulation — Competition Regulation.” The additional regulations to which we are subject has affected our competitiveness in the past and may materially hurt our profitability and impede our ability to compete effectively against our competitors in the future.

The ongoing global pandemic of a new strain of coronavirus (“COVID-19”) and any possible recurrence of other types of widespread infectious diseases may adversely affect our business, financial condition or results of operations.

COVID-19, an infectious disease caused by severe acute respiratory syndrome coronavirus 2 that was first reported to have been transmitted to humans in late 2019 and has since spread globally, has materially and adversely affected the global economy and caused significant volatility in global financial markets to date as well as disrupted our business operations. The World Health Organization declared COVID-19 as a pandemic in March 2020. We have implemented remote work arrangements for most of our employees at our headquarters and certain other locations from time to time in light of the Government’s recommendation for social distancing. In addition, the travel restrictions imposed by governments in response to the COVID-19 pandemic has resulted in a decrease in revenue from roaming services, and the pandemic has also contributed to lower customer demand for new wireless devices, resulting in a decrease in our wireless device sales revenue. While we do not believe that the COVID 19 pandemic and the resulting temporary remote work arrangements or such decreases in revenue have had a material adverse impact on our business to date, a prolonged outbreak of COVID-19 may result in further disruption in the normal operations of our business, including implementation of further work arrangements requiring employees to work remotely and/or temporary closures of our facilities, which may, among others, lead to a reduction in labor

 

11


Table of Contents

productivity, as well as further decrease in revenue from roaming services or wireless device sales.

Other risks associated with a prolonged outbreak of COVID-19 or other types of widespread infectious diseases include:

 

   

an increase in unemployment among, and/or a decrease in disposable income of, our customers, who may not be able to meet payment obligations or otherwise choose to decrease their spending levels, which in turn may decrease demand for some of our products and services or cause an increase in delinquent subscriber accounts;

 

   

a slowdown in the rate of subscriber migration to our 5G service, which generally entails higher-priced subscription plans and wireless devices;

 

   

disruptions in operations, and/or a decrease in the demand for products and services, of our corporate customers, which in turn may decrease such customers’ demand for our services and products;

 

   

service disruptions, outages and performance problems due to capacity constraints caused by an overwhelming number of people accessing our services simultaneously;

 

   

disruptions in supply of mobile handsets or telecommunications equipment from our vendors as well as in the installation of our network infrastructure;

 

   

unstable global and Korean financial markets, which may adversely affect our ability to meet capital funding needs on a timely and cost-effective basis;

 

   

a decrease in the fair value of our investments in companies that may be adversely affected by the pandemic; and

 

   

depreciation of the Won against major foreign currencies, which in turn may increase the cost of imported equipment necessary for expansion and enhancement of our telecommunications infrastructure.

It is not possible to predict the duration or full magnitude of harm from COVID-19. In the event that COVID-19 or other types of widespread infectious diseases cannot be effectively and timely contained, our business, financial condition and results of operations may be adversely affected.

Declines in the market value of our equity holdings in SK Hynix and the results of operations of SK Hynix could have a material adverse effect on the market price of our common shares and American Depositary Shares (“ADSs”) as well as our results of operation.

As of December 31, 2020, we held a 20.1% equity interest in SK Hynix, which is listed on the KRX KOSPI Market of the Korea Exchange (the “KRX KOSPI Market”) and is one of the world’s largest memory-chip makers by revenue. As of December 31, 2020, the fair value of our holding in SK Hynix was Won 17,312.9 billion. We received dividend payments of Won 146.1 billion in 2020, Won 219.2 billion in 2019 and Won 146.1 billion in 2018 related to such shareholding.

From time to time, the memory semiconductor industry has experienced significant and sometimes prolonged downturns, which often occur in connection with a deterioration of global economic conditions, and is subject to intense competition. For example, SK Hynix and its subsidiaries, on a consolidated basis, incurred net losses of Won 158.8 billion and Won 56.0 billion in 2012 and 2011, respectively, primarily due to increased supply and weak demand for semiconductor products. Although the memory semiconductor industry has recovered since then and SK Hynix has been reporting net profits since 2013, the industry is subject to cyclical fluctuations, and we expect that there may be future downturns in the industry. Uncertainty in the global economy has increased in recent years, especially with global financial and capital markets experiencing substantial volatility in light of the ongoing global COVID-19 pandemic. Accordingly, SK Hynix’s operating results would be adversely affected if it fails to compete successfully or decrease manufacturing costs at an adequate level. Our share of any net losses incurred by SK Hynix would be reflected in our income statement as share of losses related to investments in associates.

Accordingly, declines in the market value of our equity holdings in SK Hynix and the results of operations of SK Hynix could have a material adverse effect on the market price of our common shares and ADSs as well as our results of operation.

We may fail to successfully complete, integrate or realize the anticipated benefits of our new acquisitions, joint ventures or other strategic alternatives or corporate reorganizations, and such transactions may negatively impact our business.

We continue to seek opportunities to develop new businesses that we believe are complementary to our existing product and service portfolio and expand our global business through selective acquisitions. We also continue to seek ways to optimize our corporate structure to maximize the value of our traditional businesses on the one hand and newly developed businesses on the other. Accordingly, we are often engaged in evaluating potential transactions and other strategic alternatives as well as corporate reorganizations, some of which may be significant in size.

For example, we completed the Tbroad Merger in April 2020 and became the third-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. In addition, in June 2019, we acquired a 34.6% interest in Incross Co., Ltd. (“Incross”), a digital advertising company, for an aggregate purchase price of Won 53.7 billion, in light of potential synergies with our media and commerce businesses. Furthermore, in order to strengthen our security business and explore potential synergies with our wireless and fixed-line business portfolio, we acquired a 55.0% interest in Life & Security Holdings Co., Ltd. (“LSH”), which owned 100% of ADT CAPS Co., Ltd. (“Former ADT CAPS”), a leading Korean physical security service company, and two sister companies, CAPSTEC Co., Ltd. and ADT SECURITY Co., Ltd. (which subsequently merged with and into Former ADT CAPS), for Won 696.7 billion in October 2018; a 100% interest in SK Infosec Co., Ltd. (“SK Infosec”), Korea’s leading information security company, in a share exchange transaction pursuant to which we issued 1,260,668 treasury shares with an aggregate book value of Won 281.2 billion in exchange for all of the outstanding common shares of SK Infosec in December 2018 from SK Inc. (which changed its English name from SK Holdings Co., Ltd. to SK Inc. as of March 29, 2021), our largest shareholder; and additional shares of id Quantique SA (“id Quantique”), a leading provider of quantum cryptography solutions for data security based in Switzerland, with Won 55.2 billion in cash and Won 5.7 billion in contribution-in-kind in 2018 and through our participation in its capital increases in 2019 and 2020, as a result of which our equity interest in id Quantique was 68.1% as of December 31, 2020. We have subsequently combined LSH, Former ADT CAPS and SK Infosec into a single entity through a series of mergers that were completed in March 2021, and the surviving entity, SK Infosec, changed its name to ADT CAPS Co., Ltd. (“ADT CAPS”) and has become the principal consolidated subsidiary that operates our security business.

We have also pursued other strategic alternatives, such as forming a strategic alliance in October 2019 with Kakao Corp. (“Kakao”), a Korean Internet company and the operator of Korea’s most popular mobile messaging application, to collaborate in the information and communication technologies (“ICT”) sector through the sale of 1,266,620 of our treasury shares to Kakao, representing a 1.6% interest, for approximately Won 300.0 billion and a concurrent issuance by Kakao of 2,177,401 of its shares, representing a 2.5% interest, to us for approximately Won 302.3 billion. In addition, in September 2019, in furtherance of our efforts to enhance the competitiveness of our media business and to promote its future growth, we acquired a minority equity stake in Content Wavve Co., Ltd. (formerly known as Content Alliance Platform Inc.) (“Content Wavve”), a joint venture established by the three major terrestrial broadcasters in Korea that operated the mobile over-the-top (“OTT”) service “POOQ,” by investing Won 90.9 billion in cash and transferring our former mobile OTT service business “oksusu” to Content Wavve. Content Wavve combined oksusu and POOQ to launch a new integrated mobile OTT service “wavve” in September 2019. As of December 31, 2020, we held 30.0% of the total outstanding shares of Content Wavve. In addition, Eleven Street is currently in discussions with Amazon.com, Inc. regarding a potential partnership. For a more detailed description of our recent investments in new businesses, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Investments in New Growth Businesses.”

Furthermore, in December 2020, we spun off our mobility business into a new wholly-owned subsidiary, T map Mobility Co., Ltd. (“T Map Mobility”), in order to enhance its competitiveness and promote its future growth, and we have also formed a strategic partnership with Uber Technologies, Inc. (“Uber”) pursuant to which Uber has invested approximately US$50 million in T Map Mobility and approximately US$100 million in UT LLC, a joint venture formed in April 2021 between T Map Mobility and Uber in which we hold a 49.0% interest. Through UT LLC, we will launch a taxi hailing service that integrates our affiliated taxi driver network and mapping and AI technologies with Uber’s ride hailing technology. See “Item 4.B. Business Overview — Other Businesses — Miscellaneous Businesses — Mobility Business.”

In order to pursue enhancement of shareholder value and acceleration of our growth, we are currently considering a potential corporate restructuring whereby we would split into a wireless and fixed-line telecommunications company (including our interest in, among others, SK Broadband) and a holding company that would hold interests in semiconductor and new ICT businesses (including our interest in, among others, SK Hynix, ADT CAPS, Eleven Street and T Map Mobility) (the “Spin-off Company”). Such restructuring would be implemented through a horizontal spin-off transaction (“injeok bunhal”) under Korean law, whereby the Spin-off Company would be newly incorporated and our existing shareholders would receive shares of the Spin-off Company on a pro rata basis. Further decisions regarding such potential spin-off, if any, are expected to be made in the first half of 2021.

While we are hoping to benefit from a range of synergies from our recent or future acquisitions and corporate reorganizations as well as develop new growth engines for our business, we may not be able to successfully complete or integrate such acquisitions, new businesses or reorganized entities and may fail to realize the expected benefits in the near term, or at all. For example, in June 2019, we disposed of our entire interest in our consolidated subsidiaries Shopkick Management Company, Inc. (“SMC”) and Shopkick, Inc. (“Shopkick”), a wholly-owned subsidiary of SMC which operates “shopkick,” a mobile reward points-based in-store shopping application, which we had acquired in October 2014, following a prolonged period of unprofitability of the shopkick business. Previously in 2018, we also recognized Won 153.4 billion and Won 52.4 billion of impairment losses for goodwill and intangible assets, respectively, in connection with Shopkick. In addition, when we enter into new businesses with partners through joint ventures or other strategic alliances, we and those partners may have disagreements with respect to strategic directions or other aspects of business, or may otherwise be unable to coordinate or cooperate with each other, any of which could materially and adversely affect our operations in such businesses. Our business may be negatively impacted if we fail to successfully integrate or realize the anticipated benefits of such transactions.

Due to the existing high penetration rate of wireless telecommunications services in Korea, we are unlikely to maintain our subscriber growth rate, which could adversely affect our results of operations.

According to data published by the MSIT and the historical population data published by the Ministry of the Interior and Safety, the penetration rate for the Korean wireless telecommunications industry as of December 31, 2020 was approximately 134.2%, which is relatively high compared to many industrialized countries. Therefore, we expect that the penetration rate for wireless telecommunications service in Korea will remain relatively stable. As a result of the already high penetration rate in Korea for wireless telecommunications services coupled with our leading market share, we expect our subscriber growth rate to decrease. Slowed growth in the penetration rate without a commensurate increase in revenues through the introduction of new services and increased use of our services by existing subscribers would likely have a material adverse effect on our financial condition, results of operations and cash flows.

Our business and results of operations may be adversely affected if we fail to acquire adequate additional frequency usage rights or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage.

One of the principal limitations on a wireless network’s subscriber capacity is the amount of frequency spectrum available for use by the network. We have acquired a number of frequency usage rights to secure bandwidth capacity to provide our broad range of services, for which we typically make an initial payment as well as pay usage fees during the license period. We made frequency usage right fee payments of Won 136.6 billion in 2020, Won 133.1 billion in 2019 and Won 151.7 billion in 2018. For more information regarding the various bandwidths that we use and the usage right fees for such bandwidths, see “Item 4.B. Business Overview — Law and Regulation — Frequency Allocation,” “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures” and note 17 of the notes to our consolidated financial statements.

The growth of our wireless data businesses has been a significant factor in the increased utilization of our bandwidth, since wireless data applications are generally more bandwidth-intensive than voice services. In particular, the increasing popularity of smartphones and data intensive applications among smartphone users has been a major factor for the high utilization of our bandwidth in recent years. Although such trend has been offset in

part by the implementation of new technologies that enable more efficient usage of our bandwidth, we expect that the current trend of increased data transmission use by our subscribers will accelerate in the near future as more subscribers migrate to our 5G network and the volume and sophistication of the multimedia content we offer through our wireless data services continue to grow in the 5G environment. While we believe that we can address the capacity constraint issue through system upgrades and efficient allocation of bandwidth, inability to address such capacity constraints in a timely manner may adversely affect our business, results of operations, financial position and cash flows. In the event we are unable to maintain sufficient bandwidth capacity, our subscribers may perceive a general slowdown of wireless telecommunications services. Growth of our wireless telecommunications business will depend in part upon our ability to effectively manage our bandwidth capacity and to implement efficiently and in a timely manner new bandwidth-efficient technologies if they become available. We cannot assure you that bandwidth constraints will not adversely affect the growth of our wireless telecommunications business.

In November 2020, the MSIT announced plans to reallocate a total of 310 MHz of frequency bandwidths whose usage terms are due to expire in 2021 to KT, LG U+ and us, 95 MHz of which will be allocated to us. The final consideration to be paid by us for such reallocated bandwidths will depend on the number of 5G cell sites constructed by us until 2022, and the aggregate consideration to be paid by KT, LG U+ and us is expected to range between approximately Won 3.2 trillion and Won 3.8 trillion. We may be required to pay a substantial amount to acquire additional bandwidth capacity in the future in order to meet increasing bandwidth demand or renew the rights to use our existing bandwidth, and we may not be successful in acquiring the necessary bandwidth to meet such demand at commercially attractive terms or at all, which may adversely affect our financial condition and results of operations.

We rely on key researchers and engineers and senior management, and the loss of the services of any such personnel or the inability to attract and retain them may negatively affect our business.

Our success depends to a significant extent upon the continued service of our research and development and engineering personnel, and on our ability to continue to attract, retain and motivate qualified researchers and engineers. In particular, our focus on leading the market in introducing new services has meant that we must aggressively recruit engineers with expertise in cutting-edge technologies. We also depend on the services of experienced key senior management, and if we lose their services, it would be difficult to find and integrate replacement personnel in a timely manner, or at all.

The loss of the services of any of our key research and development and engineering personnel or senior management without adequate replacement, or the inability to attract new qualified personnel, would have a material adverse effect on our operations.

We need to observe certain financial and other covenants under the terms of our debt instruments, the failure to comply with which would put us in default under those instruments.

Certain of our debt instruments contain financial and other covenants with which we are required to comply on an annual and semi-annual basis. The financial covenants with respect to SK Telecom’s debt instruments include, but are not limited to, a maximum net debt-to-EBITDA ratio of 3.50 and a minimum EBITDA-to-total interest expense ratio of 4.00, each as determined on a separate financial statement basis. The debt arrangements also contain negative pledge provisions limiting our ability to provide liens on our assets as well as cross-default and cross-acceleration clauses, which give related creditors the right to accelerate the amounts due under such debt if an event of default or acceleration has occurred with respect to our existing or future indebtedness, or if any material part of our indebtedness or indebtedness of our subsidiaries is capable of being declared payable before the stated maturity date. In addition, such covenants restrict our ability to raise future debt financing.

If we breach our financial or other covenants, our financial condition will be adversely affected to the extent we are not able to cure such breaches or repay the relevant debt.

We may have to make further financing arrangements to meet our capital expenditure requirements and debt payment obligations.

We have had, and expect to continue to have, significant capital expenditure requirements as we continue to build out, maintain and upgrade our networks and invest in businesses that complement our wireless and fixed-line

telecommunication businesses. We spent Won 3,557.8 billion for capital expenditures in 2020. We expect to spend a similar amount for capital expenditures in 2021 compared to 2020 for a range of projects, including investments to expand and improve our newly implemented 5G network, investments to maintain our LTE network and LTE-A services, investments to improve and expand our Wi-Fi network, investments to develop our IoT solutions and platform services business portfolio, including AI solutions, investments in data infrastructure, investments in research and development of 5G technology, investments in businesses that can potentially leverage our 5G network, and funding for mid- to long-term research and development projects, as well as other initiatives, primarily related to the development of new growth businesses, as well as initiatives related to our ongoing businesses in the ordinary course. In November 2020, the MSIT announced plans to reallocate a total of 310 MHz of frequency bandwidths whose usage terms are due to expire in 2021 to KT, LG U+ and us, 95 MHz of which will be allocated to us. The final consideration to be paid by us for such reallocated bandwidths will depend on the number of 5G cell sites constructed by us until 2022, and the aggregate consideration to be paid by KT, LG U+ and us is expected to range between approximately Won 3.2 trillion and Won 3.8 trillion. We would be required to spend additional amounts on capital expenditures in connection with building out our networks on such reallocated bandwidths.

In particular, we continue to make significant capital investments to expand and upgrade our wireless networks in response to growing bandwidth demand by our subscribers. Bandwidth usage by our subscribers has rapidly increased in recent years primarily due to the increasing popularity of smartphones and data intensive applications among smartphone users. If heavy usage of bandwidth-intensive services grows beyond our current expectations, we may need to invest more capital than currently anticipated to expand the bandwidth capacity of our networks or our customers may have a suboptimal experience when using our services. Any of these events could adversely affect our competitive position and have a material adverse effect on our business, financial condition, results of operation and cash flow. For a more detailed discussion of our capital expenditure plans and a discussion of other factors that may affect our future capital expenditures, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures.”

As of December 31, 2020, we had Won 2,163.4 billion in contractual payment obligations due in 2021, which mostly involve repayment of debt obligations, payments related to lease liabilities and other short-term leases and leases of low-value assets and payments related to frequency licenses. See “Item 5.B. Liquidity and Capital Resources — Contractual Obligations and Commitments.”

We have not arranged firm financing for all of our current or future capital expenditure plans and contractual payment obligations. We have, in the past, obtained funds for our proposed capital expenditure and payment obligations from various sources, including our cash flow from operations as well as from financings, primarily debt and equity financings. Any material adverse change in our operational or financial condition could impact our ability to fund our capital expenditure plans and contractual payment obligations. Still volatile financial market conditions may also curtail our ability to obtain adequate funding. Inability to fund such capital expenditure requirements may have a material adverse effect on our financial condition, results of operations and business. In addition, although we currently anticipate that the capital expenditure levels estimated by us will be adequate to meet our business needs, such estimates may need to be adjusted based on developments in technology and markets. In the event we are unable to meet any such increased expenditure requirements or to obtain adequate financing for such requirements, on terms acceptable to us, or at all, this may have a material adverse effect on our financial condition, results of operations and business.

Termination or impairment of our relationship with a small number of key suppliers for network equipment and for leased lines could adversely affect our results of operations, financial position and cash flows.

We purchase wireless network equipment from a small number of suppliers. To date, we have purchased substantially all of the equipment for our networks from Samsung Electronics Co., Ltd. (“Samsung Electronics”), Ericsson-LG Co., Ltd. (“Ericsson-LG”) and Nokia Corporation (“Nokia”). We believe Samsung Electronics currently manufactures more than half of the wireless handsets sold to our subscribers. Although other manufacturers sell the equipment we require, sourcing such equipment from other manufacturers could result in unanticipated costs in the maintenance and enhancement of our wireless networks. Inability to obtain the equipment needed for our networks in a timely manner may have an adverse effect on our business, financial condition, results of operations and cash flows.

Table of Contents

We cannot assure you that we will be able to continue to obtain the necessary equipment from one or more of our suppliers. Any discontinuation or interruption in the availability of equipment from our suppliers for any reason could have an adverse effect on our results of operations. In addition, inability to lease adequate lines at commercially reasonable rates may impact the quality of the services we offer and may also damage our reputation and our business.

Our business relies on technology developed by us, and our business will suffer if we are unable to protect our proprietary rights.

We own numerous patents and trademarks worldwide, and have applications for patents pending in many countries. In addition to active research and development efforts, our success depends in part on our ability to obtain patents and other intellectual property rights covering our services.

We may be required to defend against charges of infringement of patent or other proprietary rights of third parties. Although we have not experienced any significant patent or other intellectual property disputes, we cannot be certain that any significant patent or other intellectual property disputes will not occur in the future. Defending our patent and other proprietary rights could require us to incur substantial expense and to divert significant resources of our technical and management personnel, and could result in our loss of rights to employ certain technologies to provide services.

Malicious and abusive Internet practices could impair our services and we may be subject to significant legal and financial exposure, damage to our reputation and a loss of confidence of our customers.

Our business involves the storage and transmission of large amounts of confidential information, and cybersecurity breaches expose us to a risk of loss of this information, which may lead to improper use or disclosure of such information, ensuing potential liability and litigation, any of which could harm our reputation and adversely affect our business.

Our cybersecurity measures may also be breached due to employee error, malfeasance or otherwise. Instituting appropriate access controls and safeguards across all our information technology infrastructure is challenging. Furthermore, outside parties may attempt to fraudulently induce employees to disclose sensitive information in order to gain access to our data or our customers’ data or accounts, or may otherwise obtain access to such data or accounts. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently and often are not recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. If an actual or perceived breach of our cybersecurity occurs or the market perception of the effectiveness of our cybersecurity measures is harmed, we may incur significant legal and financial exposure, including legal claims and regulatory fines and penalties, damage to our reputation and a loss of confidence of our customers, which could have an adverse effect on our business, financial condition and results of operations.

In addition, our wireless and fixed-line subscribers increasingly utilize our network to access the Internet and, as a consequence, we or they may become victim to common malicious and abusive Internet activities, such as unsolicited mass advertising (i.e., “spam”), hacking of personal information and dissemination of viruses, worms and other destructive or disruptive software. These activities could have adverse consequences on our network and our customers, including degradation of service, excessive call volume to call centers and damage to our or our customers’ equipment and data. Significant incidents could lead to customer dissatisfaction and, ultimately, loss of customers or revenue, in addition to increased costs to us to service our customers and protect our network. Any significant loss of our subscribers or revenue due to incidents of malicious and abusive Internet practices or significant increase in costs of serving those subscribers could adversely affect our business, financial condition and results of operations.

Labor disputes may disrupt our operations.

Although we have never experienced any significant labor disputes, there can be no assurance that we will not experience labor disputes in the future, including protests and strikes, which could disrupt our business operations and have an adverse effect on our financial condition and results of operation.

Table of Contents

Every two years, the union and management negotiate and enter into a new collective bargaining agreement that has a two-year duration, which is focused on employee benefits and welfare. Employee wages are separately negotiated on an annual basis. Although we consider our relations with our employees to be good, there can be no assurance that we will be able to maintain such a working relationship with our employees and will not experience labor disputes resulting from disagreements with the labor union in the future.

Concerns that radio frequency emissions may be linked to various health concerns could adversely affect our business and we could be subject to litigation relating to these health concerns.

In the past, allegations that serious health risks may result from the use of wireless telecommunications devices or other transmission equipment have adversely affected share prices of some wireless telecommunications companies in the United States. In May 2011, the International Agency for Research on Cancer (the “IARC”), a part of the World Health Organization, announced that it has classified radiofrequency electromagnetic fields associated with wireless phone use as possibly carcinogenic to humans, based on an increased risk for glioma, a malignant type of brain cancer. The IARC conducts research on the causes of human cancer and the mechanisms of carcinogenesis and aims to develop scientific strategies for cancer control. We cannot assure you that these health concerns will not adversely affect our business. Several class action and personal injury lawsuits have been filed in the United States against several wireless phone manufacturers and carriers, asserting product liability, breach of warranty and other claims relating to radio transmissions to and from wireless phones. Certain of these lawsuits have been dismissed. We could be subject to liability or incur significant costs defending lawsuits brought by our subscribers or other parties who claim to have been harmed by or as a result of our services. In addition, the actual or perceived risk of wireless telecommunications devices could have an adverse effect on our business by reducing the number of our subscribers or the usage per subscriber.

Our ability to deliver services may be disrupted due to a systems failure, shutdown in our networks or natural disaster.

Our services are currently carried through our wireless and fixed-line networks, which could be vulnerable to damage or interruptions in operations due to fires, floods, earthquakes, power losses, telecommunication failures, network software flaws, unauthorized access, computer viruses and similar events, which may occur from time to time. The occurrence of any of these events could impact our ability to deliver services, we may be liable for damages to our customers caused by such interruptions, our reputation may be damaged and our customers may lose confidence in us, which could have a negative effect on our results of operations.

Depreciation of the value of the Won against the Dollar and other major foreign currencies may have a material adverse effect on our results of operations and the market value of our common shares and ADSs.

Substantially all of our revenues are denominated in Won. Depreciation of the Won may materially affect our results of operations because, among other things, it causes:

 

   

an increase in the amount of Won required by us to make interest and principal payments on our foreign currency-denominated debt; and

 

   

an increase, in Won terms, of the costs of equipment that we purchase from overseas sources which we pay for in Dollars or other foreign currencies.

Fluctuations in the exchange rate between the Won and the Dollar will affect the Dollar equivalent of the Won price of the our common shares on the KRX KOSPI Market. These fluctuations also will affect:

 

   

the amounts a registered holder or beneficial owner of ADSs will receive from the American Depositary Receipt (“ADR”) depositary in respect of dividends, which will be paid in Won to the ADR depositary and converted by the ADR depositary into Dollars;

 

   

the Dollar value of the proceeds that a holder will receive upon sale in Korea of our common shares; and

 

   

the secondary market price of our ADSs.

If SK Inc. causes us to breach the foreign ownership limitations on our common shares by being deemed to be a foreign entity, we may experience a change of control.

The Telecommunications Business Act currently sets a 49.0% limit on the aggregate foreign ownership of our issued shares. Under the Telecommunications Business Act, as amended, a Korean entity, such as SK Inc., is deemed to be a foreign entity if its largest shareholder (determined by aggregating the shareholdings of such shareholder and its related parties) is a foreigner and such shareholder (together with the shareholdings of its related parties) holds 15.0% or more of the issued voting stock of the Korean entity. As of December 31, 2020, SK Inc. owned 21,624,120 shares of our common stock, or 26.8%, of our issued shares. SK Inc. is currently not deemed to be a foreign entity. However, should SK Inc. be considered to be a foreign shareholder in the future, then its shareholding in us would be included in the calculation of our aggregate foreign shareholding and our aggregate foreign shareholding (based on our foreign ownership level as of December 31, 2020, which we believe was 33.4%) would exceed the 49.0% ceiling on foreign shareholding. As of December 31, 2020, the two largest foreign shareholders of SK Inc. each held a 3.5% stake therein.

If our aggregate foreign shareholding limit is exceeded, the MSIT may issue a corrective order to us, the breaching shareholder (including SK Inc. if the breach is caused by an increase in foreign ownership of SK Inc.) and the foreign shareholder which owns in the aggregate 15.0% or more of SK Inc. Furthermore, if SK Inc. is considered a foreign shareholder, it will be prohibited from exercising its voting rights with respect to the shares held in excess of the 49.0% ceiling, which may result in a change in control of us. In addition, the MSIT will be prohibited from granting us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49.0%. For a description of further actions that the MSIT could take, see “Item 4.B. Business Overview — Law and Regulation — Foreign Ownership and Investment Restrictions and Requirements.”

Risks Relating to Korea

Unfavorable financial and economic developments in Korea may have an adverse effect on us.

We are incorporated in Korea, and a substantial portion of our operations and assets are located in Korea. As a result, we are subject to political, economic, legal and regulatory risks specific to Korea. The economic indicators in Korea in recent years have shown mixed signs of growth and uncertainty, and starting in 2020, the overall Korean economy and the economies of Korea’s major trading partners have shown signs of deterioration due to the debilitating effects of the COVID-19 pandemic. See “— The ongoing global pandemic of a new strain of coronavirus (“COVID-19”) and any possible recurrence of other types of widespread infectious diseases may adversely affect our business, financial condition or results of operations.” As a result, future growth of the Korean economy is subject to many factors beyond our control, including developments in the global economy.

In recent years, adverse conditions and volatility in the worldwide financial markets, fluctuations in oil and commodity prices and the increasing weakness of the global economy, in particular due to the COVID-19 pandemic, have contributed to the uncertainty of global economic prospects in general and have adversely affected, and may continue to adversely affect, the Korean economy. The value of the Won relative to major foreign currencies has fluctuated significantly and, as a result of deteriorating global and Korean economic conditions, there has been significant volatility in the stock prices of Korean companies recently. Future declines in the Korea Composite Stock Price Index (known as the “KOSPI”) and large amounts of sales of Korean securities by foreign investors and subsequent repatriation of the proceeds of such sales may adversely affect the value of the Won, the foreign currency reserves held by financial institutions in Korea and the ability of Korean companies to raise capital. Any future deterioration of the Korean or global economy could adversely affect our business, financial condition and results of operations.

Developments that could have an adverse impact on Korea’s economy include:

 

   

adverse conditions or developments in the economies of countries and regions that are important export markets for Korea, such as China, the United States, Europe and Japan, or in emerging market economies in Asia or elsewhere, including as a result of deteriorating economic and trade relations between the United States and China as well as increased uncertainties resulting from the United Kingdom’s exit from the European Union;

Escalations in tensions with North Korea could have an adverse effect on us and the market value of our common shares and ADSs.

Relations between Korea and North Korea have been tense throughout Korea’s modern history. The level of tension between the two Koreas has fluctuated and may increase abruptly as a result of future events. In particular, there have been heightened security concerns in recent years stemming from North Korea’s nuclear weapon and ballistic missile programs as well as its hostile military actions against Korea. Some of the significant incidents in recent years include the following:

 

   

North Korea renounced its obligations under the Nuclear Non-Proliferation Treaty in January 2003 and has conducted six rounds of nuclear tests since October 2006, including claimed detonations of hydrogen bombs, which are more powerful than plutonium bombs, and warheads that can be mounted on ballistic missiles. Over the years, North Korea has also conducted a series of ballistic missile tests, including missiles launched from submarines and intercontinental ballistic missiles that it claims can reach the United States mainland. In response, the Government has repeatedly condemned the provocations and flagrant violations of relevant United Nations Security Council resolutions. In February 2016, the Government also closed the inter-Korea Gaesong Industrial Complex in response to North Korea’s fourth nuclear test in January 2016. Internationally, the United Nations Security Council has passed a series of resolutions condemning North Korea’s actions and significantly expanding the scope of sanctions applicable to North Korea, most recently in December 2017 in response to North Korea’s intercontinental ballistic missile test in November 2017. Over the years, the United States and the European Union have also expanded their sanctions applicable to North Korea.

 

   

In March 2010, a Korean naval vessel was destroyed by an underwater explosion, killing many of the crewmen on board. The Government formally accused North Korea of causing the sinking, while North Korea denied responsibility. Moreover, in November 2010, North Korea fired more than one hundred artillery shells that hit Korea’s Yeonpyeong Island near the Northern Limit Line, which acts as the de facto maritime boundary between Korea and North Korea on the west coast of the Korean peninsula, causing casualties and significant property damage. The Government condemned North Korea for the attack and vowed stern retaliation should there be further provocation.

North Korea’s economy also faces severe challenges, which may further aggravate social and political pressures within North Korea. Although bilateral summit meetings were held between Korea and North Korea in April, May and September 2018 and between the United States and North Korea in June 2018, February 2019 and June 2019, there can be no assurance that the level of tensions affecting the Korean peninsula will not escalate in the future. Any increase in tensions, which may occur, for example, if North Korea experiences a leadership crisis, high-level contacts between Korea or the United States and North Korea break down or military hostilities occur, could have a material adverse effect on our business, results of operations and financial condition and the market value of our common shares and ADSs.

Korea’s legislation allowing class action suits related to securities transactions may expose us to additional litigation risk.

The Securities-related Class Action Act of Korea enacted in January 2004 allows class action suits to be brought by shareholders of companies (including us) listed on the KRX KOSPI Market for losses incurred in connection with purchases and sales of securities and other securities transactions arising from (1) false or inaccurate statements provided in the registration statements, prospectuses, annual reports, audit reports, semi-annual or quarterly reports and material fact reports and omission of material information in such documents, (2) insider trading, (3) market manipulation and (4) unfair trading. This law permits 50 or more shareholders who collectively hold 0.01% of the shares of a company to bring a class action suit against, among others, the issuer and its directors and officers. Because of the relatively recent enactment of the act, there is not enough judicial precedent to predict how the courts will apply the law. Litigation can be time-consuming and expensive to resolve, and can divert management time and attention from the operation of a business. We are not aware of any basis upon which such suit may be brought against us, nor are any such suits pending or threatened. Any such litigation brought against us could have a material adverse effect on our business, financial condition and results of operations.

There are special risks involved with investing in securities of Korean companies, including the possibility of restrictions being imposed by the Government in emergency circumstances.

As we are a Korean company and operate in a business and cultural environment that is different from that of other countries, there are risks associated with investing in our securities that are not typical for investments in securities of companies in other jurisdictions.

Under the Korean Foreign Exchange Transactions Act, if the Government deems that certain emergency circumstances, including a significant disruption in the international balance of payments and international financial markets or extreme difficulty in carrying out currency, exchange rate or other macroeconomic policies due to the movement of capital between Korea and other countries, are likely to occur, it may impose any necessary restriction such as requiring Korean or foreign investors to obtain prior approval from the Ministry of Economy and Finance (the “MOEF”) for the acquisition of Korean securities or for the repatriation of interest, dividends or sales proceeds arising from Korean securities or from disposition of such securities or other transactions involving foreign exchange. See “Item 10.D. Exchange Controls — Korean Foreign Exchange Controls and Securities Regulations.”

Risks Relating to Securities

Sales of our shares by SK Inc. and/or other large shareholders may adversely affect the market value of our common shares and ADSs.

Sales of substantial amounts of our common shares, or the perception that such sales may occur, could adversely affect the prevailing market value of our common shares or ADSs or our ability to raise capital through an offering of our common shares.

As of December 31, 2020, SK Inc. owned 26.8% of our total issued common shares and has not agreed to any restrictions on its ability to dispose of our shares. See “Item 7.A. Major Shareholders.” We can make no prediction as to the timing or amount of any sales of our common shares. We cannot assure you that future sales of our common shares, or the availability of our common shares for future sale, will not adversely affect the prevailing market value of our common shares or ADSs from time to time.

We believe that we may be classified as a passive foreign investment company, or PFIC, for U.S. federal income tax purposes for our taxable year ending December 31, 2020 and that there is a significant risk that we will be classified as a PFIC in the current and future taxable years, which could subject U.S. investors in our common shares or ADSs to significant adverse U.S. federal income tax consequences.

As a result of changes in the composition and value of our assets as implied by the price of our ADSs, we believe that we may be classified as a “passive foreign investment company,” or “PFIC,” for U.S. federal income tax purposes for our taxable year ending December 31, 2020, and that there is a significant risk that we will be a PFIC for the current and future taxable years.

A non-U.S. corporation will be a PFIC if, in any particular taxable year, either (a) 75% or more of its gross income for such year consists of certain types of “passive” income or (b) 50% or more of the value of its assets (generally determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income.

If we are classified as a PFIC in any taxable year, a U.S. holder (as defined in “Item 10.E. Additional Information — Taxation — United States Federal Income Tax Considerations”) may incur significantly increased U.S. federal income tax on gain recognized on the sale or other disposition of the common shares or ADSs and on the receipt of distributions on the common shares or ADSs to the extent such gain or distribution is treated as an “excess distribution” under the U.S. federal income tax rules, and such U.S. holder may be subject to burdensome reporting requirements. The amount of income tax on any excess distributions will be increased by an interest charge to compensate for tax deferral, calculated as if the excess distributions were earned ratably over the period that the U.S. holder holds its common shares or ADSs. Further, if we are a PFIC for any year during which a U.S. holder holds our commons shares or ADSs, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. holder holds our common shares or ADSs unless we cease to be a PFIC and the U.S. holder makes a special election.

 

22


Table of Contents

A U.S. holder may be able to avoid the unfavorable rules described above by electing to mark its ADSs to market, provided the ADSs are treated as “marketable stock.” The ADSs generally will be treated as marketable stock if the ADSs are “regularly traded” on a “qualified exchange or other market” (which includes the New York Stock Exchange). Further, it should be noted that only the ADSs and not the common shares are listed on the New York Stock Exchange. Consequently, a U.S. holder that holds common shares that are not represented by ADSs may not be eligible to make a mark-to-market election in respect of those common shares.

U.S. holders are strongly urged to consult their own tax advisors regarding our potential classification as a PFIC and regarding the U.S. federal income tax consequences of acquiring, holding, and disposing of our common shares or ADSs if we are so classified, including the advisability of making a “mark-to-market” election, if available. See “Item 10.E. Additional Information — Taxation — United States Federal Income Tax Considerations — Passive Foreign Investment Company Rules” for more details.

If an investor surrenders his or her ADSs to withdraw the underlying shares, he or she may not be allowed to deposit the shares again to obtain ADSs.

Under the deposit agreement, holders of our common shares may deposit those shares with the ADR depositary’s custodian in Korea and obtain ADSs, and holders of ADSs may surrender ADSs to the ADR depositary and receive our common shares. However, under the terms of the deposit agreement, as amended, the depositary bank is required to obtain our prior consent to any such deposit if, after giving effect to such deposit, the total number of our common shares represented by ADSs, which was 6,600,692 shares as of March 31, 2021, exceeds a specified maximum, which was 24,321,893 shares as of March 31, 2021, subject to adjustment under certain circumstances. In addition, the depositary bank or the custodian may not accept deposits of our common shares for issuance of ADSs under certain circumstances, including (1) if it has been determined by us that we should block the deposit to prevent a violation of applicable Korean laws and regulations or our articles of incorporation or (2) if a person intending to make a deposit has been identified as a holder of at least 4.0% of our common shares. It is possible that we may not give the consent. Consequently, an investor who has surrendered his or her ADSs and withdrawn the underlying shares may not be allowed to deposit the shares again to obtain ADSs.

An investor in our ADSs may not be able to exercise preemptive rights for additional new shares and may suffer dilution of his or her equity interest in us.

The Korean Commercial Code and our articles of incorporation require us, with some exceptions, to offer shareholders the right to subscribe for new shares in proportion to their existing ownership percentage whenever new shares are issued. If we offer a right to subscribe for additional new common shares or any other rights of similar nature, the ADR depositary, after consultation with us, may make the rights available to an ADS holder or use reasonable efforts to dispose of the rights on behalf of the ADS holder and make the net proceeds available to the ADS holder. The ADR depositary, however, is not required to make available to an ADS holder any rights to purchase any additional shares unless it deems that doing so is lawful and feasible and:

 

   

a registration statement filed by us under the Securities Act is in effect with respect to those shares; or

 

   

the offering and sale of those shares is exempt from, or is not subject to, the registration requirements of the Securities Act.

We are under no obligation to file any registration statement with respect to any ADSs. If a registration statement is required for an ADS holder to exercise preemptive rights but is not filed by us, the ADS holder will not be able to exercise his or her preemptive rights for additional shares. As a result, ADS holders may suffer dilution of their equity interest in us.

Short selling of our ADSs by purchasers of securities convertible or exchangeable into our ADSs could materially adversely affect the market price of our ADSs.

SK Inc., through one or more special purpose vehicles, has engaged and may in the future engage in monetization transactions relating to its ownership interest in us. These transactions have included and may include offerings of securities that are convertible or exchangeable into our ADSs. Many investors in convertible or

 

23


Table of Contents

exchangeable securities seek to hedge their exposure in the underlying equity securities at the time of acquisition of the convertible or exchangeable securities, often through short selling of the underlying equity securities or similar transactions. Since a monetization transaction could involve debt securities linked to a significant number of our ADSs, we expect that a sufficient quantity of ADSs may not be immediately available for borrowing in the market to facilitate settlement of the likely volume of short selling activity that would accompany the commencement of a monetization transaction. This short selling and similar hedging activity could place significant downward pressure on the market price of our ADSs, thereby having a material adverse effect on the market value of ADSs owned by you.

A holder of our ADSs may not be able to enforce a judgment of a foreign court against us.

We are a corporation with limited liability organized under the laws of Korea. Substantially all of our directors and officers and other persons named in this document reside in Korea, and all or a significant portion of the assets of our directors and officers and other persons named in this document and substantially all of our assets are located in Korea. As a result, it may not be possible for holders of our ADSs to effect service of process within the United States, or to enforce against us any judgments obtained from the United States courts based on the civil liability provisions of the federal securities laws of the United States. There is doubt as to the enforceability in Korea, either in original actions or in actions for enforcement of judgments of United States courts, of civil liabilities predicated on the United States federal securities laws.

We are generally subject to Korean corporate governance and disclosure standards, which may differ from those in other countries.

Companies in Korea, including us, are subject to corporate governance standards applicable to Korean public companies, which may differ in some respects from standards applicable in other countries, including the United States. As a reporting company registered with the SEC and listed on the New York Stock Exchange (the “NYSE”), we are subject to certain corporate governance standards as mandated by the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”). However, foreign private issuers, including us, are exempt from certain corporate governance requirements under the Sarbanes-Oxley Act or under the rules of the NYSE. There may also be less publicly available information about Korean companies, such as us, than is regularly made available by public or non-public companies in other countries. Such differences in corporate governance standards and less public information available could result in corporate governance practices or disclosures that are perceived as less than satisfactory by investors in certain countries.

INFORMATION ON THE COMPANY

 

Item 4.A.

History and Development of the Company

As Korea’s first wireless telecommunications service provider, we have a recognized history of leadership and innovation in the domestic telecommunications sector. Today, we remain Korea’s leading wireless telecommunications services provider and have continued to pioneer the commercial development and implementation of state-of-the-art wireless technologies. We had 31.4 million wireless subscribers, including MVNO subscribers leasing our networks, as of December 31, 2020, representing a market share of 45.1%, the largest market share among Korean wireless telecommunications service providers. We believe we are also a leader in developing new products and services that reflect the increasing convergence of telecommunications technologies, as well as the growing synergies between the telecommunications sector and other industries, and are well-positioned to become Korea’s leading platform service provider through our next-generation growth businesses in media, security, commerce, mobility, IoT solutions and other innovative products offered through our platform services, including AI solutions.

In February 2012, we acquired an equity stake in SK Hynix, one of the world’s largest memory-chip makers by revenue, for an aggregate purchase price of Won 3.4 trillion, and became its largest shareholder. As of December 31, 2020, we held a 20.1% equity interest in SK Hynix.

On March 31, 2021, we had a market capitalization of approximately Won 22.2 trillion (US$19.7 billion, as translated at the noon buying rate of March 31, 2021) or approximately 1.0% of the total market capitalization on

the KRX KOSPI Market, making us the 17th largest company listed on the KRX KOSPI Market based on market capitalization on that date. Our ADSs, each representing one-ninth of one share of our common stock, have traded on the NYSE since June 27, 1996.

We are a corporation with limited liability organized under the laws of Korea. We established our telecommunications business in March 1984 under the name Korea Mobile Telecommunications Co., Ltd. We changed our name to SK Telecom Co., Ltd., effective March 21, 1997. In January 2002, we merged with Shinsegi Telecom Co., Ltd. (“Shinsegi”), which was then the third-largest wireless telecommunications service provider in Korea. Our registered office is at SK T-Tower, 65, Eulji-ro, Jung-gu, Seoul 04539, Korea and our telephone number is +82-2-6100-2114. Our website address is http://www.sktelecom.com.

The SEC maintains a website (http://www.sec.gov), which contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC.

Korean Telecommunications Industry

Established in March 1984, we became the first wireless telecommunications service provider in Korea. We remained the sole provider of wireless telecommunications services until April 1996, when Shinsegi commenced cellular service. The Government began to introduce competition into the fixed-line and wireless telecommunications services markets in the early 1990’s. During this period, the Government allowed new competitors to enter the fixed-line sector, sold a controlling stake in us to the SK Group, and granted a cellular license to our first competitor, Shinsegi. In October 1997, three additional companies began providing wireless telecommunications services under Government licenses to provide wireless telecommunications services. In 2000 and 2001, the Korean wireless telecommunications market experienced significant consolidation. In January 2002, Shinsegi was merged into us. Additionally, two of the other wireless telecommunications services providers merged.

There are currently three mobile network operators in Korea: our company, KT and LG U+. As of December 31, 2020, the market share of the Korean wireless telecommunications market, in terms of number of subscribers, of KT and LG U+ was approximately 31.4% and 23.5%, respectively (compared to our market share of 45.1%), each including MVNO subscribers leasing the respective networks. As of December 31, 2020, MVNOs had a combined market share of 13.1%, of which MVNOs leasing our networks represented 3.3%, MVNOs leasing KT’s networks represented 7.1% and MVNOs leasing LG U+’s networks represented 2.7%.

Telecommunications industry growth in Korea has been among the most rapid in the world, with fixed-line penetration being under five lines per 100 population in 1978 and increasing to 47.9 lines per 100 population as of December 31, 2006 before decreasing to 24.8 lines per 100 population as of December 31, 2020, and wireless penetration increasing from 7.0 subscribers per 100 population in 1996 to 134.2 subscribers per 100 population as of December 31, 2020. The table below sets forth certain subscription and penetration information regarding the Korean telecommunications industry as of the dates indicated:

other businesses, which include our portal service, mobility business, marketing platform business and certain other miscellaneous businesses.

Our Business Strategy

We believe that the current trends in the Korean telecommunications industry are characterized by technological change, evolving consumer needs and increasing digital convergence. Against the backdrop of these industry trends, we aim to maintain our leading position in the Korean market for wireless telecommunications services and actively develop our next-generation growth businesses in media, security, commerce, mobility, IoT solutions and other innovative products offered through our platform services. We plan to further utilize our big data analysis capabilities to create products and services that are tailored to our customers’ evolving needs, as well as incorporate AI capabilities directly into many of the products and services we offer. By doing so, we strive to become a socially respected “New ICT Leader” as universally recognized by our customers, business partners and shareholders. To take advantage of evolving industry trends and further realize our corporate vision to become a “New ICT Leader,” we have undertaken the following strategic initiatives:

 

   

Maintain our leadership in the wireless services business by offering innovative 5G services and customer-oriented products and services and evolve into a subscription-based marketing company. We plan to maintain our leadership in the wireless services business by offering innovative 5G services that provide differentiated subscriber experiences. We also plan to promote the proliferation of 5G services by offering services and content that are specialized for the 5G environment, such as cloud gaming, hands-on experience services and e-sports. In addition, we will continue to analyze the needs of our subscribers leveraging our AI technology and provide products and services that meet such needs. Furthermore, we intend to broaden the range of our product and service offerings for subscription to new business areas such as rental, gaming and overseas shipment and further expand our subscriber base to promote our growth and evolve into a “subscription-based marketing company.”

 

   

Develop our next-generation growth businesses through hyper-collaboration. We believe that we have evolved from being a domestic telecommunications provider in Korea to possessing the fundamental capabilities that enable us to pursue a broad range of collaboration in the field of ICT with both domestic and international partners. We have formed strategic partnerships with industry leaders to create synergies in various areas, such as 5G cloud gaming, mobile edge computing (“MEC”) and e-sports, and we are continually expanding the areas for collaboration. We aim to create an environment for “hyper-collaboration” to develop and foster our next-generation growth businesses.

 

   

Develop our technological capabilities and new products and services to support our 5G network. We aim to continue developing cutting-edge technologies that will be adopted as the technological standard for 5G services. In addition, we will seek to apply our 5G infrastructure and capabilities to our various other key businesses such as media, security and commerce to create unique new products and services geared to serve evolving customer needs. Furthermore, we aim to collaborate with various partners to identify new business opportunities that can potentially leverage our 5G network.

 

   

Pursue sustainable management to seek mutual growth with the broader society. The SK Management System, which is the business philosophy and foundation of corporate culture of the SK Group, includes as a key component the goal of growing together with the broader society by contributing to its economic growth and creating social value. Based on a socially accountable governance system led by the Corporate Citizenship Committee of our board of directors, we aim to pursue the “double bottom line” of achieving long-term shareholder value as well as creating social value by leveraging our business capabilities, thereby contributing to the well-being of all stakeholders and the enhancement of our corporate value in the long-term.

As part of our ongoing efforts to pursue such strategies, we are currently considering a potential corporate restructuring whereby we would split into a wireless and fixed-line telecommunications company (including our interest in, among others, SK Broadband) and the Spin-off Company, which would hold interests in semiconductor and new ICT businesses (including our interest in, among others, SK Hynix, ADT CAPS, Eleven Street and T Map Mobility). Such restructuring would be implemented through a horizontal spin-off transaction (“injeok bunhal”)

 

27


Table of Contents

under Korean law, whereby the Spin-off Company would be newly incorporated and our existing shareholders would receive shares of the Spin-off Company on a pro rata basis. Further decisions regarding the potential spin-off, if any, are expected to be made in the first half of 2021.

Cellular Services

We offer wireless voice and data transmission services, sell wireless devices and provide IoT solutions and innovative platform services through our cellular services segment. Our wireless voice and data transmission services are offered through our backbone networks that collectively can be accessed by approximately 99.0% of the Korean population. We had 31.4 million wireless subscribers, including MVNO subscribers leasing our networks, as of December 31, 2020, representing a market share of 45.1%, the largest market share among Korean wireless telecommunications service providers. We launched our wireless services using our 5G network in April 2019, and we are continually expanding our 5G network coverage and enhancing service quality. The table below sets forth the number of subscribers, including subscribers of MVNOs that lease our wireless networks, using our various digital wireless networks as of the dates indicated:

In July 2020, we terminated our second generation wireless services using our CDMA network. CDMA subscribers as of December 31, 2020 consist of subscribers who have not upgraded to our other networks or terminated their subscriptions as of such date.

In 2020, 2019 and 2018, our cellular services segment revenue was Won 12,295.7 billion, Won 12,177.5 billion and Won 12,378.9 billion, respectively, representing 66.0%, 68.6% and 73.4%, respectively, of our consolidated revenue.

Wireless Services

We offer wireless voice transmission and data transmission services to our subscribers through our backbone networks. Our wireless telecommunications services are available to our subscribers receiving service under the SK Telecom brand. In addition, customers can obtain wireless telecommunications services that operate on our network from MVNOs that lease our wireless networks. We derive revenues from our wireless telecommunications service principally through monthly plan-based fees as described in “— Rate Plans” below.

We provide a voice-over-LTE service, known as our “HD Voice” service, to all of our LTE and 5G subscribers featuring high-quality voice transmission, fast call connection, voice-to-video call switching and digital content sharing during calls. We also offer our subscribers a wide range of wireless data transmissions services. Our messaging service allows our subscribers to send and receive text, graphic, audio and video messages. In addition, our subscribers can access a wide variety of digital content and services through mobile applications providing music, video, gaming, news, commerce and financial services as well as solutions that enable subscribers to access the Internet and e-mail. We intend to continue to build our wireless data services as a platform for growth, extending our portfolio of wireless data services and developing new content for our subscribers.

Through service agreements with various foreign wireless telecommunications service providers, we offer cellular global roaming services, branded as our “T-Roaming” service. Global roaming services allow subscribers traveling abroad to make and receive calls using their regular mobile phone numbers. In addition, we provide global roaming service to foreigners traveling to Korea. In such cases, we generally receive a fee from the traveler’s local wireless telecommunications service provider.

Through SK Telink, we also operate our MVNO business under the brand “SK 7Mobile,” which we believe offers excellent quality at reasonable rates utilizing SK Telecom’s wireless networks. SK Telink is focused on developing low-cost distribution channels and targeting niche customer segments that have a lower average revenue per user than that of SK Telecom’s subscriber base.

In addition, we provide interconnection service to connect our networks to domestic and international fixed-line and other wireless networks. See “— Interconnection” below.

Wireless Device Sales

We offer several categories of wireless devices, including smartphones and basic phones, tablets and other Internet access devices and wearable devices that are sold through an extensive distribution network, which consists of authorized exclusive dealers and independent retailers, as well as branch offices and stores directly operated by us through our wholly-owned subsidiary, PS&Marketing Co., Ltd. (“PS&Marketing”).

We have also integrated NUGU into our T map service as well as our B tv service as further discussed in “— Other Businesses — Miscellaneous Businesses — Mobility Business” and “— Fixed-line Telecommunication Services — Advanced Media Platform (including IPTV and Cable TV Services).”

In addition, we integrated NUGU into our “T phone” service, which offers our customers a number of convenient call functions, such as a spam-call blocking function and a search function that informs customers of the phone numbers of shops, hospitals and other facilities closest to the customer’s current location. The integrated “T phone × NUGU” service allows T phone users to search phone numbers, make calls, send text messages and experience other AI-based services through voice commands. Through Dreamus Company, we also offer “NUGU buds,” which are wireless earbuds that enable users to launch and operate “T phone × NUGU” while wearing them without touching their smartphones.

In 2018, we launched “NUGU developers,” a platform on which third-party manufacturers and developers can create and launch new services based on NUGU technology and incorporate NUGU capabilities into their applications or devices. In 2020, we launched “NUGU carecall” in response to the COVID-19 pandemic, which is a service that tracks and records symptoms of persons subject to monitoring through mobile phones. We continue to explore ways in which we can leverage our NUGU technology to launch new, and enhance our existing, products and services.

Other New Businesses

We are preparing to launch a variety of integrated cloud services based on our advanced 5G MEC technology and platform for business customers that require secure and ultra-low latency communications, focusing on the media, logistics, healthcare, finance and manufacturing industries. We completed the construction of MEC infrastructure at four strategic locations during 2020 and we launched our first MEC-based cloud service, “5GX Edge Cloud,” in collaboration with Amazon Web Services in December 2020. We have entered into strategic partnerships with Amazon Web Services and other leading cloud service providers to pursue further collaboration on MEC-based cloud services. We also plan to provide smart factory solutions that can leverage our 5G technology and MEC-based cloud services, beginning with SK Hynix, which we expect to result in enhanced efficiency for its semiconductor manufacturing process.

Rate Plans

We offer our wireless telecommunications services on both a postpaid and prepaid basis. Approximately 96.4% of our subscribers received our wireless telecommunications services on a postpaid basis as of December 31, 2020. Postpaid accounts primarily represent retail subscribers under contract with SK Telecom under which a subscriber is billed in advance a monthly fixed rate in return for a monthly network service allowance and usage for outgoing voice calls and wireless data services beyond the allowance is billed in arrears, where payment of the total amount of the bill is due at the end of the month.

Digital Wireless Network

We offer wireless voice and data transmission services throughout Korea using digital wireless networks, primarily consisting of our 5G network, LTE network, WCDMA network, Wi-Fi network and LoRa network. We continually upgrade and increase the capacity of our wireless networks to keep pace with advancements in technology, the growth of our subscriber base and the increased usage of voice and wireless data services by our subscribers. For more information about our capital expenditures relating to our wireless networks, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures.”

5G Network.    5G is the state-of-the-art wireless network that enables data to be transmitted at speeds faster than our LTE network with lower latency. We began the operation of our 5G network in December 2018 on a limited basis for business customers, beginning with a few major commercial districts in Seoul and other metropolitan areas. In April 2019, we launched wireless service plans using the 5G network following the commencement of sales of the first 5G-compatible smartphones, and we are in the process of expanding our 5G network coverage, focusing on major commercial districts and other densely-populated areas in the Seoul metropolitan area and other cities. As part of this coverage expansion, as of December 31, 2020, we have established 189 “5G Clusters” with high 5G connectivity at strategic locations where customers are able to experience the full potential of our 5G network through augmented reality and virtual reality services, cloud gaming and other ICT products. Our 5G services provide a maximum data transmission speed of 2.75 Gbps, and our 5G penetration was 17.4% as of December 31, 2020. We have also deployed our 5G network for mMTC connections relating to our IoT solutions.

We believe that our 5G technology and network infrastructure enable us to provide the fastest 5G data transmission network nationwide. In December 2020, the MSIT announced that our 5G network provided the fastest upload and download speeds among the three mobile network operators, KT, LG U+ and us. The nationwide average download speed of our 5G network was 795.6 Mbps compared to 667.5 Mbps for KT’s 5G network and 608.5 Mbps for LG U+’s 5G network.

LTE Network.    LTE technology has become widely accepted globally as the standard fourth generation technology and enables data to be transmitted at speeds faster than our WCDMA network. Since first commencing our LTE services in July 2011 and LTE-A services, which use carrier aggregation technology that combines spectrum frequencies to improve data transmission speeds, in June 2013, we have developed and launched various upgraded LTE networks and services providing faster network speeds, enhanced connectivity and broader coverage areas. In February 2018, we launched four-band LTE-A services utilizing 4x4 multiple-input multiple-output (“MIMO”) technology providing for data transmission speeds of up to 1 Gbps, and we commenced five-band LTE-A services using 4x4 MIMO technology that provide data transmission speeds of up to 1.15 Gbps in March 2019 and up to 1.25 Gbps in March 2020. With these developments in LTE technology, our LTE penetration increased to 72.8% as of December 31, 2020 compared to 49.3% as of December 31, 2013. We expect that wireless services based on LTE technology will continue to be used broadly by our users in the near future, as we and our competitors continue to build up 5G networks and services and wireless service users gradually migrate to the 5G network over time, and plan to continue to deploy improved LTE-A technology to increase the maximum data transmission speed of our services. For machine-to-machine connections relating to our IoT solutions, we launched our LTE-M services at speeds of up to 10 Mbps in March 2016, as well as our LTE Cat.M1 services at speeds of up to 0.03 Mbps in April 2018. Upgrades to our LTE technology in recent years have enabled even faster data transmission speeds, as shown below.

We believe that our advanced LTE technology and dense network infrastructure enable us to provide the fastest LTE data transmission network nationwide. In December 2020, the MSIT announced that our LTE network provided the fastest upload and download speeds among the three mobile network operators, KT, LG U+ and us. The nationwide average download speed of our LTE network was 207.7 Mbps compared to 142.1 Mbps for KT’s LTE network and 109.5 Mbps for LG U+’s LTE network.

The faster data transmission speed of our LTE network has allowed us to offer significantly improved wireless data transmission services, providing our subscribers with faster wireless access to multimedia content. We have been building new access networks and evolved packet cores for our LTE network, while we utilize our existing WCDMA network for other parts of our LTE network.

WCDMA and CDMA Networks.    WCDMA technology enables us to offer significantly faster and higher-quality voice and data transmission and supports more sophisticated wireless data transmission services than is possible through our former CDMA network. Since first commencing our WCDMA services in Seoul in 2003, we have expanded our WCDMA network nationwide and implemented various technologies to improve data transmission speeds within our WCDMA network.

CDMA technology is a continuous digital transmission technology that accommodates higher throughput than analog technology by using various coding sequences to allow concurrent transmission of voice and data signals for wireless communication. In January 1996, we launched our first wireless network based on CDMA technology and became the world’s first to commercialize second generation cellular services using the CDMA network. As a result of declining usage and the increasing difficulty of maintaining the network, we terminated our second generation CDMA wireless services in July 2020.

Wi-Fi Network.    Wi-Fi technology enables our subscribers with Wi-Fi-capable devices such as smartphones, laptops and tablet computers to access mobile Internet. We started to build Wi-Fi access points in 2010 and, as of

 

33


Table of Contents

December 31, 2020, we had more than 117,000 Wi-Fi access points in public areas such as shopping malls, restaurants, coffee shops, subways and airports where, generally, the demand for high-speed wireless Internet service is high. While each Wi-Fi access point typically has a radius of approximately 20-30 meters, some of our Wi-Fi hot zones, which have multiple Wi-Fi access points, including those installed at public transportation facilities and amusement parks, have much wider service areas.

LoRa Networks.    A Low-Power Wide-Area network based on LoRa technology is a type of telecommunications network designed to support communication among IoT devices. It can transmit data over tens of kilometers while consuming much less power than LTE networks, lowering costs for connectivity as well as lowering battery power usage. We completed the nationwide deployment of our LoRa network in July 2016. We expect that our LoRa network will provide the infrastructure necessary for the growth of not only our own IoT solutions business but also the IoT industry as a whole.

Network Infrastructure

The principal components of our wireless networks are:

 

   

cell sites, which are physical locations equipped with transmitters, receivers and other equipment that communicate by radio signals with wireless handsets within range of the cell (typically a 3 to 40 kilometer radius);

 

   

switching stations, which switch voice and data transmissions to their proper destinations, which may be, for instance, a mobile phone of one of our subscribers (for which transmissions would originate and terminate on our wireless networks), a mobile phone of a KT or LG U+ subscriber (for which transmissions would be routed to KT’s or LG U+’s wireless networks, as applicable), a fixed-line telephone number (for which calls would be routed to the public switched telephone network of a fixed-line network operator), an international number (for which calls would be routed to the network of a long distance service provider) or an Internet site; and

 

   

transmission lines, which link cell sites to switching stations and switching stations with other switching stations.

As of December 31, 2020, our 5G, LTE and WCDMA networks had an aggregate of 57,932 cell sites. As we continue to expand our 5G network coverage, the number of our cell sites is expected to increase accordingly.

We have purchased substantially all of the equipment for our networks from Samsung Electronics, Ericsson–LG and Nokia. Most of the transmission lines we use, including virtually all of the lines linking switching stations, as well as a portion of the lines linking cell sites to switching stations, comprise optical fiber lines that we own and operate directly. However, we have not undertaken to install optical fiber lines to link every cell site and switching station. In places where we have not installed our own transmission lines, we have leased lines from KT and LG U+. We intend to increase the efficiency of our network utilization and provide optimal services by internalizing transmission lines.

We use a wireless network surveillance system. This system oversees the operation of cell sites and allows us to monitor our main equipment located throughout the country from one monitoring station. The automatic inspection and testing provided to the cell sites lets the system immediately rebalance to the most suitable setting, and the surveillance system provides for automatic dispatch of repair teams and quick recovery in emergency situations.

Marketing, Distribution and Customer Service

Marketing.    Our marketing strategy is focused on offering solutions tailored to the needs of our various customer segments, promoting our brand and leveraging our extensive distribution network. Our marketing plan includes a coordinated program of television, print, radio, outdoor signage, Internet and point-of-sale media promotions designed to relay a consistent message across all of our markets. We market our wireless products and services under the “T” brand, which signifies the centrality of “Telecommunications” and “Technology” to our business and also seeks to emphasize our commitment to providing “Top” quality, “Trustworthy” products and services to our customers.

Table of Contents

We have implemented certain information technology improvements in connection with our marketing strategy, including customer management systems, as well as more effective information security controls. We believe these upgrades have enhanced our ability to process and utilize marketing- and subscriber-related data, which, in turn, has helped us to develop more effective and targeted marketing strategies. We currently operate a customer information system designed to provide us with an extensive customer database. Our customer information system includes a billing system that provides us with comprehensive account information for internal purposes and enables us to efficiently respond to customer requests. Our customers can also change their rate plans, verify the charges accrued on their accounts, receive their bills online and send text messages to our other subscribers through our website at www.tworld.co.kr and through our “T world” mobile application.

We strive to improve subscriber retention through our T Membership program, which is a membership service available to our wireless subscribers. Our T Membership program provides various membership benefits to its members such as discounts with our membership partners for dining, shopping, entertainment and travel, access to our online membership shopping mall and invitations to various promotional events. Although our competitors also have similar membership programs, we believe that our T Membership program has a competitive advantage over our competitors’ membership programs due to our large subscriber base and breadth of membership benefits.

Distribution.    We use a combination of an extensive network, including branch offices and stores, directly operated by us through our subsidiary, PS&Marketing, more than 3,200 authorized exclusive dealers and an extensive network of independent retailers in order to increase subscriber growth while reducing subscriber acquisition costs.

As part of our initiative to provide a differentiated customer service experience, we operate T Premium Stores that allow our potential and existing subscribers to experience certain of our services such as services that are available through our IoT solutions and platform services. As of December 31, 2020, we operated more than 600 T Premium Stores. In October 2020, we opened “T Factory,” a facility that offers a wide range of experiences with wireless devices as well as our subscription services and also includes an unmanned store that is open seven days a week and 24 hours a day.

In addition, we operate an online distribution channel, “T Direct Shop,” through which subscribers can conveniently purchase wireless devices and subscribe to our services online. We also operate a dedicated online shop on 11st, our e-commerce marketplace. We intend to continue to develop our online distribution channel to leverage our offline distribution capabilities to provide convenience and additional value to our subscribers. For example, subscribers purchasing wireless devices through T Direct Shop can opt to pick up their devices at one of our offline stores.

Currently, authorized dealers are entitled to an initial commission for each new subscriber registered by the dealer, as well as an average ongoing commission calculated as a percentage of that subscriber’s monthly plan-based rate for the first five years. In order to strengthen our relationships with our exclusive dealers, we offer a dealer financing plan, pursuant to which we provide to each authorized dealer a loan of up to Won 4.0 billion with a repayment period of up to three years. As of December 31, 2020, we had an aggregate of Won 96.8 billion outstanding in loans to authorized dealers.

Customer Service.    We provide high-quality customer service directly through our two subsidiaries, Service Ace Co., Ltd. and Service Top Co., Ltd., rather than rely on outsourcing. SK O&S Co., Ltd. operates our switching stations and related transmission and power facilities and offers quality customer service primarily to our business customers. We have held the top position with respect to our telecommunications service and retail sales service in Korea’s leading three customer satisfaction indices, the National Customer Satisfaction Index, the Korean Customer Satisfaction Index and the Korean Standard Service Quality Index, for 23 years, 23 years and 21 years, respectively.

In September 2019, we acquired a minority equity stake in Content Wavve, which operated the mobile OTT service “POOQ,” and transferred our former mobile OTT service business “oksusu” to Content Wavve. Content Wavve combined oksusu and POOQ to launch a new integrated mobile OTT service “wavve” in September 2019. See “— Other Investments and Relationships — Wavve” below.

We continue to expand the scope of our media services and content offerings to provide our subscribers with a vast library of high-quality content that can be accessed through our wireless networks and our fixed-line network.

Business Communications Services

We offer other business communications services to our business customers, including corporations and government entities. Our business communications services include leased line solutions, Internet data center solutions and network solution services.

Our leased line solutions are exclusive lines that allow point-to-point connection for voice and data traffic between two or more geographically separate points. We hold a license to operate leased line services on a nationwide basis in Korea and also use international transmission lines to provide leased line services to other countries. Our leased line services enable high volumes of data to be transmitted swiftly and reliably. We also provide back-up storage for transmitted data. Through our Internet data centers, we provide our business subscribers with server-based support including co-location, dedicated server hosting and cloud computing services. Our network solution service utilizes our network infrastructure and voice platform to provide 24-hour monitoring and control of our customers’ networks. Through this service, we conduct remote monitoring of our customers’ data and voice communications infrastructure and network and traffic conditions, and carry out preventive examinations and on-site visits.

Rate Plans

For our residential customers, we offer both bundled rate plans for a combination of our fixed-line service offerings as well as individual rate plans for each separate service offering. Bundled rate plans are offered at a discount compared to subscribing to the same services through individual rate plans. Approximately 86% of subscribers to our fixed-line services subscribe to two or more of our services through our bundled rate plans. Bundled rate plans for a combination of fixed-line telephone, broadband Internet access and IPTV or cable TV services, which are subject to a contract of one to three years, range from Won 30,800 to Won 67,650 per month, depending on the services included and the length of the contract. We also offer bundled rate plans combining our fixed-line communication services with our wireless services and physical security services, respectively.

Our “5,000 minute” plan for subscribers to our fixed-line telephone service features 5,000 voice minutes for domestic land-to-land calls for a fixed rate and range from Won 7,700 to Won 11,550 per month depending on whether or not the subscriber opts for a contract and if so, the length of the contract period. We offer individual fixed-rate plans for our broadband Internet access service that range from Won 25,410 to Won 104,500 per month depending on the data throughput speed and existence and length of a contract. We offer individual fixed-rate plans for our IPTV and cable TV services that range from Won 4,400 to Won 25,300 per month depending on the number

of channels provided and existence and length of a contract. In addition, subscribers can purchase individual videos on demand or subscribe to certain paid content on a periodic basis.

With respect to our business communications services, we offer rates that are tailored to the specific needs of our business customers. We also charge certain installation fees and equipment rental fees as well as other ancillary fees with respect to certain of our fixed-line telecommunications services.

Marketing, Distribution and Customer Service

We focus on bringing our fixed-line telephone, broadband Internet and advanced media platform services (including IPTV and cable TV services) to residential users, and various business communications services to corporate users. We market our fixed-line telecommunications products and services under the “B” brand. Our “B” brand signifies the centrality of “Broadband” to our business and also seeks to emphasize our commitment to providing the “Best” quality products and services to our customers that go “Beyond” expectations, leading to a “Bravo” response. Our “B” brand also strengthens our shared identity with our wireless service’s “T” brand.

We currently outsource a significant portion of our retail sales force needs. We market our services and provide after-sales service support to customers through more than 60 customer centers and a network of more than 310 authorized exclusive dealers located throughout Korea. In addition, SK Telecom’s direct retail stores and authorized dealers for wireless telecommunications services also market our fixed-line telephone, broadband Internet and advanced media platform services (including IPTV and cable TV services), which we believe has contributed to the increase in the number of subscribers to such services. We have contracts with our customer centers to sell our services exclusively. These centers receive a commission for each service contract and installation contract secured. In addition, we pay these centers for the maintenance and repair work that they perform for our subscribers. Customer and service centers often enter into sub-contracts with smaller distribution outlets within their area to increase their sales coverage and engage in telemarketing efforts. Authorized dealers are entitled to an initial commission for each new subscriber registered by the dealer.

Sales to business subscribers are handled through our in-house sales group. Our sales teams focus on securing contracts with large commercial complexes, allowing us to install our remote terminals at their premises. After installation, sales teams direct their attention to individual business clients within these premises. Sales teams that have secured contracts with business clients remain the primary contacts for all aspects of the client’s needs, including further installation and customer and follow-up service.

Security Services

Our security business consists of physical security services and information security services provided by ADT CAPS. In 2020, 2019 and 2018, our security services segment revenue was Won 1,246.5 billion, Won 1,109.5 billion and Won 284.3 billion, respectively, representing 6.7%, 6.3% and 1.7%, respectively, of our consolidated revenue. Our security services businesses, which were previously part of our other businesses segment in 2018, were reclassified as a new security services segment in 2019.

ADP CAPS (formerly known as SK Infosec), the surviving entity resulting from the merger of LSH with and into SK Infosec in December 2020 and the merger of Former ADT CAPS with and into SK Infosec in March 2021, operates our security business. We currently own approximately 62.6% of the equity interest in ADT CAPS. We had acquired Former ADT CAPS, which operated our physical security business prior to such mergers, in October 2018 by acquiring a 55.0% interest in LSH, which owned 100% of Former ADT CAPS, for Won 696.7 billion. In December 2018, we merged NSOK Co., Ltd. (“NSOK”), which became our consolidated subsidiary in 2014 and provided residential and small business electronic security and other related alarm monitoring services, with and into Former ADT CAPS. We had acquired SK Infosec, which operated our information security business prior to the mergers, from SK Inc., our largest shareholder, in a share exchange transaction in December 2018, pursuant to which we transferred 1,260,668 treasury shares with an aggregate book value of Won 281.2 billion to SK Inc. in exchange for all of the issued and outstanding common shares of SK Infosec.

Physical Security

We provide a variety of physical security services utilizing our flagship unmanned surveillance and dispatch platform called the Central Monitoring Services (“CMS”), which are tailored for residential and commercial needs and operate through a centralized monitoring system that provides offsite surveillance through cameras, sensors and emergency alarms. Upon detecting any suspicious activity through such system or upon request, security personnel is dispatched to the relevant subscriber location to provide further onsite manned security.

We provide services that utilize synergies between our security business and other key business segments, such as “T Safe Security,” a CMS-based video surveillance and security guard dispatch service offered through the distribution channels for our wireless services. In addition, we offer bundle-based discounted rate plans such as “T&CAPS” and “B&CAPS,” which bundle our wireless service and broadband Internet service, respectively, with our physical security service. Beginning in June 2019, with the launch of T map Parking, we also operate a parking management and security solutions business. See “— Other Businesses — Miscellaneous Businesses — Mobility Business” below.

In response to the COVID-19 pandemic, we have also launched a range of services in 2020 related to disease preventive measures as well as remote work arrangements, such as “CAPS Smart Check” and “CAPS Smart Walk-In,” access security solutions with face recognition and thermometer functions, “CAPS Cleancare,” a disinfection and extermination service, and “CAPS Office Home,” a remote work office solution with information technology and security infrastructure.

Information Security

Our information security services consist of information security consulting services, managed security services as well as cyber threat intelligence solutions. Our representative product is “Secudium IoT,” a convergence security service that combines information, physical and operational technology security services into a single platform.

Commerce Services

Our commerce services segment consists primarily of “11st,” our online marketplace business operated by Eleven Street, and “SK stoa,” our interactive T-commerce network. In 2020, 2019 and 2018, our commerce services segment revenue was Won 792.9 billion, Won 710.7 billion and Won 728.4 billion, respectively, representing 4.3%, 4.0% and 4.3%, respectively, of our consolidated revenue. Following the entry into an agreement to transfer SK Broadband’s 100% equity interest in SK Stoa to SK Telecom in April 2019 (which transaction was completed in January 2020), the T-commerce business operations of SK Stoa, which were previously part of our fixed-line telecommunications services segment in 2018, were reclassified as part of our commerce services segment for 2019.

E-Commerce

11st is an online open marketplace that offers a wide range of products through an online and mobile platform. Individual consumers can buy a vast array of products such as clothes and accessories, beauty products, groceries, baby products, books, office supplies, furniture, home goods, outdoor and sporting goods, appliances, electronics, travel packages, entertainment tickets and local deals for restaurants and other services from small- to large-sized retailers that operate “mini malls” on the 11st platform. Eleven Street also operates SK Pay, a convenient and secure payment service through which users can register their credit card to simplify payments for online and mobile purchases for many of our services, including 11st.

As of December 31, 2020, 11st was the second-largest commerce platform in terms of the total number of unique visitors to its mobile and desktop versions, according to Nielsen Koreanclick. The mobile version of 11st, which has grown significantly in recent years, accounted for 68%, 64% and 62% of 11st’s annual gross merchandise volume, which represents the total annual monetary value of customer purchases of goods and services, net of estimated refunds. We intend to continue our efforts to increase usage of the mobile version of 11st, enhance the convenience of our 11st mobile and web user interface and create synergies with our other products and services.

Eleven Street was spun-off as our new consolidated subsidiary from SK Planet Co., Ltd. (“SK Planet”) in September 2018. In connection with such spin-off, Eleven Street received a Won 500 billion equity investment in the form of redeemable convertible preferred shares from a group of financial investors led by H&Q Korea Partners, LLC, pursuant to which such financial investors held an 18.2% equity interest in Eleven Street as of December 31, 2020.

T-Commerce

We also operate a T-commerce network, “SK stoa,” through our consolidated subsidiary SK Stoa, which offers a broad assortment of goods and services through pre-recorded television programming. The goods and services promoted on SK stoa’s T-commerce programming can be purchased through telephone orders, SK stoa’s mobile application or online open marketplace, or a virtual application appearing on the television screen using the viewer’s remote controller. In March 2019, SK Stoa launched “SK stoa ON,” which offers searchable shopping programming that is available to viewers at their convenience by utilizing video-on-demand capabilities. In September 2019, SK Stoa launched “Hellen Karen,” its own private fashion brand. SK stoa also acts as the exclusive T-commerce distributor for certain products and services of SK Group companies, such as food, electronics, home appliances and car rentals.

Other Businesses

We strive to continually diversify our products and services and develop new growth engines that we believe are complementary to our existing products and services, which we include in our other businesses segment. In 2020, 2019 and 2018, our other businesses segment revenue was Won 883.9 billion, Won 803.0 billion and Won 660.1 billion, respectively, representing 4.7%, 4.5% and 3.9%, respectively, of our consolidated revenue.

Mobility Business

We provide mobility services through T Map Mobility, a wholly-owned subsidiary of SK Telecom created as a result of a spin-off of SK Telecom’s mobility business into a newly incorporated entity as of December 29, 2020. As a result of such spin-off, our mobility business, which was previously part of our cellular services segment, became a part of our other businesses segment beginning December 29, 2020.

Our mobility services is offered through our “T map” platform, which is the leading global positioning system (“GPS”) navigation service in Korea provided to our and our competitors’ wireless subscribers free of charge. T map uses GPS technology to transmit driving directions, real-time traffic updates and emergency rescue assistance to wireless devices. As of December 31, 2020, there were approximately 12.4 million monthly average users of our T map service. We have integrated our AI platform, NUGU, into our T map service to enable users to use voice commands to operate its navigation functions as well as their mobile devices, such as calling, text messaging and music streaming, while driving to enhance the convenience and safety of T map users.

T map also offers a taxi-hailing service called “T map Taxi,” as well as “T map Parking,” a parking service launched in June 2019 that combines our ICT technology with ADT CAPS’ parking management and security solutions to provide users with real-time information related to parking lot locations, availability, rates and discounts, in addition to automatic payment services in the case of select parking lots, including those operated by ADT CAPS, through a dedicated mobile application. As of December 31, 2020, T map Taxi and T map Parking had approximately 0.6 million and 0.1 million monthly active users, respectively.

We have entered into strategic partnerships with global ride-hailing service providers. In January 2019, we formed Grab Geo Holdings PTE. LTD., a joint venture in which we hold a 30.0% interest, with Grab, the leading ride-hailing service provider in Southeast Asia. Through this joint venture, we launched a navigation service for Grab drivers based on T map’s key technologies, including big data analysis algorithms and ultra-precise GPS solutions, in Singapore, and we plan to expand such service to other countries in which Grab operates. We also formed a strategic partnership with Uber pursuant to which Uber has invested approximately US$50 million in T Map Mobility and approximately US$100 million in UT LLC, a joint venture formed in April 2021 between T Map Mobility and Uber in which we hold a 49.0% interest. Through UT LLC, we will launch a taxi hailing service that integrates our affiliated taxi driver network and mapping and AI technologies with Uber’s ride hailing technology.

In April 2021, T Map Mobility agreed to receive a Won 400 billion equity investment in the form of common shares from financial investors, Affirma Capital and EastBridge Partners, pursuant to which such financial investors will each hold a 14.0% equity interest in T Map Mobility. The transaction is expected to close in May 2021.

Marketing Platform Business

We provide marketing platform services through SK Planet, which include the following:

 

   

Syrup Wallet, a mobile wallet service that is the successor to our Smart Wallet service, allows users to conveniently manage membership card points and payment methods such as coupons, credit cards and gift vouchers on their mobile devices for both online and offline purchases and provides shopping information to users in certain shopping areas using advanced location-based technology; and

 

   

OK Cashbag, a loyalty points program which allows members to collect and redeem loyalty points at its partnering merchants and offers differentiated marketing services to such partnering merchants.

Portal Service

We offer a portal service under our “Nate” brand name through SK Communications. Nate can be accessed through its website, www.nate.com, or through its mobile application. Nate offers a wide variety of content and services, including Nate Search, an Internet search engine, Nate News, which provides a library of articles about current events, sports, entertainment and culture, Nate Pann, a user-generated content service as well as access to free e-mail accounts through Nate Mail.

Others

We offer high-end audio devices under the brand name “Astell&Kern” that are manufactured by our subsidiary, Dreamus Company (“Dreamus”). Dreamus also operates our personalized music platform “FLO,” which provides a music streaming service with customized music recommendations and user interfaces by analyzing individual user preferences with our AI technology. In 2018, we acquired an additional equity interest in Dreamus for Won 65.0 billion, and as of December 31, 2020, we had a 51.4% equity interest in Dreamus.

We also operate a mobile application marketplace, “One Store,” in collaboration with KT, LG U+ and NAVER Corporation. Through this joint collaboration, we expect to increase the competitiveness of One Store to compete with Google Playstore, the leading mobile application marketplace in Korea. In recent years, we have made offerings of mobile games as the focus of One Store in response to the rapid growth of the mobile game market in Korea. In November 2019, One Store Co., Ltd., our consolidated subsidiary that operates One Store, undertook a capital increase of approximately Won 97.5 billion by issuing convertible preferred shares to a consortium of financial investors including Kiwoom Investment and SKS Private Equity. As of December 31, 2020, we held 52.1% of the total outstanding shares of One Store Co., Ltd.

In addition, in order to strengthen our data security capabilities in light of expected increases in data transmission by wireless service subscribers and users of our IoT solutions through our 5G network, we acquired a controlling equity interest in id Quantique, a leading provider of quantum cryptography solutions for data security based in Switzerland, in 2018. As of December 31, 2020, we held a 68.1% equity interest in id Quantique.

In June 2019, we acquired a 34.6% interest in Incross, a digital advertising company that provides mobile, online and other forms of digital advertising solutions, for an aggregate purchase price of Won 53.7 billion, in light of potential synergies with our media and commerce businesses. Although we own less than a majority of Incross’s outstanding equity interest, Incross is deemed to be our consolidated subsidiary based on our management’s determination that we have sufficient control.

We also provide freight and logistics consulting services to corporate customers through FSK L&S Co. Ltd. (“FSK L&S”), a joint venture with a subsidiary of Foxconn Technology Group of Taiwan, in which we hold a 60.0% equity interest as of December 31, 2020. We acquired such 60.0% equity interest from SK Inc. in February 2018 for approximately Won 18.0 billion. We accounted for FSK L&S as an associate under the equity method in 2018, but following our determination that we have obtained control of FSK L&S during 2019, FSK L&S has become a consolidated subsidiary beginning in 2019.

Interconnection

Our wireless and fixed-line networks interconnect with the public switched telephone networks operated by KT and SK Broadband and, through their networks, with the international gateways of KT and LG U+, as well as the networks of the other wireless telecommunications service providers in Korea. These connections enable our subscribers to make and receive calls from telephones outside our networks. Under Korean law, certain service providers, including us, are required to permit other service providers to interconnect to their networks. If a new service provider desires interconnection with the networks of an existing service provider but the parties are unable to reach an agreement within 90 days, the new service provider can appeal to the KCC.

Domestic Calls

Guidelines issued by the MSIT require that all interconnection charges levied by a regulated carrier take into account (i) the actual costs to that carrier of carrying a call or (ii) imputed costs. The MSIT determines interconnection rates applicable to each carrier based on changes in traffic volume, taking into account other factors such as research results, competition and trends in technology development.

Wireless-to-Fixed-line.    According to our interconnection arrangement with KT, for a call from our wireless network to KT’s fixed-line network, we collect the usage rate from our wireless subscriber and in turn pay KT the interconnection charges. Similarly, KT pays interconnection charges to SK Broadband for a call from KT’s wireless network to SK Broadband’s fixed-line network. The interconnection rate applicable to both KT and SK Broadband was Won 8.56 per minute, Won 9.15 per minute and Won 9.99 per minute for 2020, 2019 and 2018 respectively.

Fixed-line-to-Wireless.    The MSIT determines interconnection arrangements for calls from a fixed-line network to a wireless network. For a call initiated by a fixed-line user to one of our wireless subscribers, the fixed-line network operator collects our usage fee from the fixed-line user and remits to us an interconnection charge. Interconnection with KT accounts for substantially all of our fixed-line-to-wireless interconnection revenue and expenses. The interconnection rate paid by fixed-line network service providers to each wireless network service provider was Won 10.61 per minute, Won 11.64 per minute and Won 13.07 per minute for 2020, 2019 and 2018, respectively.

Wireless-to-Wireless.     Interconnection charges also apply to calls between wireless telephone networks in Korea. Under these arrangements, the operator originating the call pays an interconnection charge to the operator terminating the call. The applicable interconnection rate is the same as the fixed-line-to-wireless interconnection rate set out in the table above.

Our revenues from the wireless-to-wireless charge were Won 449.1 billion in 2020, Won 463.8 billion in 2019 and Won 498.5 billion in 2018. Our expenses from these charges were Won 451.6 billion in 2020, Won 464.1 billion in 2019 and Won 494.2 billion in 2018. The charges above were agreed among the parties involved and confirmed by the KCC.

International Calls and International Roaming Arrangements

With respect to international calls, if a call is initiated by our wireless subscribers, we bill the wireless subscriber for the international charges of KT, LG U+ or SK Broadband, and we receive interconnection charges from such operators. If an international call is received by our subscriber, KT, LG U+ or SK Broadband pays interconnection charges to us based on our imputed costs.

To complement the services we provide to our subscribers in Korea, we offer international voice and data roaming services. We charge our subscribers usage fees for global roaming service and, in turn, pay foreign wireless network operators fees for the corresponding usage of their network. For a more detailed discussion of our global roaming services, see “— Wireless Services” above.

Competition

We operate in highly saturated and competitive markets, and we believe that our subscriber growth is affected by many factors, including the expansion and technical enhancement of our networks, the development and deployment of new technologies, the effectiveness of our marketing and distribution strategy, the quality of our

customer service, the introduction of new products and services, competitive pricing of our rate plans, new market entrants and regulatory changes.

Historically, there has been considerable consolidation in the telecommunications industry, resulting in the current competitive landscape comprising three mobile and fixed network operators in the Korean market, KT, LG U+ and us. Each of our competitors has substantial financial, technical, marketing and other resources to respond to our business offerings.

The following table shows the market share information, based on number of subscribers, as of December 31, 2020, for the following markets.

 

     Market Share (%)

Includes MVNO subscribers that lease the wireless networks of the respective mobile network operator.

 

(2)

Includes video-on-demand only service subscribers. Market share is expressed as a percentage of the pay TV market (which includes IPTV, cable TV and satellite TV).

 

(3)

Consists of 16.1% from our IPTV service and 8.3% from our cable TV service.

 

(4)

Consists of 24.9% from KT’s IPTV service and 7.3% from its satellite TV service provided through KT Skylife Co, Ltd., a subsidiary of KT.

 

(5)

Consists of 14.0% from LG U+’s IPTV service and 11.0% from its cable TV service provided through LG HelloVision, a subsidiary of LG U+.

Cellular Services

As of December 31, 2020, we had 31.4 million subscribers, representing a market share of approximately 45.1%, including MVNO subscribers leasing our networks. As of December 31, 2020, KT and LG U+ had 21.8 million and 16.3 million subscribers, respectively, representing approximately 31.4% and 23.5%, respectively, of the total number of wireless subscribers in Korea on such date, each including MVNO subscribers leasing its networks. As of December 31, 2020, we had 5.5 million 5G subscribers and KT and LG U+ had 3.6 million and 2.8 million 5G subscribers, respectively, each including MVNO subscribers leasing its networks. As of December 31, 2020, we had 22.8 million LTE subscribers and KT and LG U+ had 16.2 million and 13.5 million LTE subscribers, respectively, each including MVNO subscribers leasing its networks.

In 2020, we had 4.4 million activations and 4.5 million deactivations. For 2020, our monthly churn rate ranged from 1.1% to 1.4%, with an average monthly churn rate of 1.2%, which remained unchanged from 2019. In 2020, we gained 41.8% of the total number of new wireless subscribers and subscribers that migrated to a different wireless telecommunications service provider, compared to KT with 30.6% and LG U+ with 27.6%.

Our competitors for subscriber activations include MVNOs, including MVNOs that lease our networks. MVNOs generally provide rate plans that are relatively cheaper than similar rate plans of the wireless network providers from which they lease their networks, including us. Currently, 14 MVNOs provide wireless telecommunications services using the networks leased from us. As of December 31, 2020, MVNOs had a combined market share of 13.1%, of which MVNOs leasing our networks represented 3.3%, MVNOs leasing KT’s networks represented 7.1% and MVNOs leasing LG U+’s networks represented 2.7%.

In addition, other companies may enter the wireless network services market. New entries in such market have historically required obtaining requisite licenses from the MSIT. However, pursuant to an amendment to the Telecommunications Business Act that went into effect in June 2019, companies meeting certain regulatory criteria

 

43


Table of Contents

may become a network service provider by registering with the MSIT without a separate license requirement, which may have the effect of encouraging new entries into the Korean wireless network services market in the future. For a description of the risks associated with the competitive environment in which we operate, see “Item 3.D. Risk Factors — Risks Relating to Our Business — Competition may reduce our market share and harm our results of operations and financial condition.”

Historically, competition in the wireless telecommunications business had caused us to significantly increase our marketing and advertising expenses from time to time depending on the prevailing competitive landscape, with our marketing expenses as a percentage of SK Telecom’s revenue, on a separate basis, reaching a peak of 28.2% in 2012. Such percentage was 24.5% in 2018, 25.6% in 2019 and 26.1% in 2020. We attribute such stabilization to the maturity of the overall wireless telecommunication market and the implementation of the MDDIA, which prohibits wireless telecommunications service providers from unfairly providing discriminatory subsidies based on certain criteria. For a more detailed discussion of the MDDIA, see “— Law and Regulation — Rate Regulation” below.

We face competition from KT and LG U+ as well as other platform service providers in our other cellular service businesses. For example, our Smart Home service competes with KT’s Giga IoT Home service and LG U+’s IoT@Home service.

Fixed-Line Telecommunication Services

Our fixed-line telephone service competes with KT and LG U+ as well as providers of other VoIP services. As of December 31, 2020, our market share of the fixed-line telephone and VoIP service market was 15.8% (including the services provided by SK Broadband and SK Telink) in terms of number of subscribers compared to KT with 56.8% and LG U+ with 19.1%.

We are the second largest provider of broadband Internet access services in Korea in terms of both revenue and subscribers, and our network covered more than 86% of households in Korea as of December 31, 2020. As of December 31, 2020, our market share of the broadband Internet market was 29.0% in terms of number of subscribers compared to KT with 41.1% and LG U+ with 20.3%.

Our IPTV and cable TV services compete with other providers of pay TV services, including KT, LG U+ and cable companies. As of December 31, 2020, our market share of the pay TV market (which includes IPTV, cable TV and satellite TV) in terms of number of subscribers was 24.4% compared to KT with 32.2% (including its IPTV and satellite TV services) and LG U+ with 25.0% (including its IPTV and cable TV services), and the collective market share of other pay TV providers was 18.4%. Furthermore, our IPTV and cable TV services are facing an increasing level of competition from global operators of online video streaming platforms, such as YouTube, Amazon Video and Netflix, and the video services offered by leading domestic online and mobile search and communications platforms including NAVER and Kakao, as such services continue to become increasingly popular to serve as a substitute to traditional television programming.

Recently, the Korean fixed-line telecommunications industry has been going through significant consolidation involving major pay television service providers. We completed the Tbroad Merger in April 2020, as a result of which we have become the third-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. In December 2019, LG U+ acquired a majority equity stake in LG HelloVision to become the second-largest pay TV provider in Korea in terms of number of subscribers as of December 31, 2020. Such transactions, as well as further consolidation in the fixed-line telecommunications industry, may result in increased competition, as the entities emerging from such consolidation and other remaining players in the industry may actively pursue expanding or protecting their respective market shares.

Furthermore, the Government has historically enforced regulations on cable TV and IPTV service providers that prohibited them from having a market share of more than one-third of the total number of subscribers in the relevant pay TV market on each of their respective platforms. In June 2015, the Government amended the regulation to impose the same limit on the market share of the entire pay TV market, including satellite TV service providers as well. Such amended regulation, however, expired in June 2018. There are bills currently pending in the National Assembly to abolish the previous market share regulations on cable TV and IPTV service providers. It is uncertain whether such bills will be passed.

Security Services

The physical security services industry in Korea is expanding rapidly due to the relatively low penetration of physical security services as compared to other developed countries, growing demand for residential security services and the popularization of unmanned services. Our physical security business competes with other large physical security service providers, including S-1 and KT Telecop. As of December 31, 2020, our market share of the physical security services market was 34% in terms of the aggregate revenue of these three companies, compared to S-1 with 55% and KT Telecop with 11%.

The information security services market in Korea is also undergoing rapid growth as various industries become more digitalized and the risk of cybersecurity breaches heightens. Our information security services compete with other providers of similar products and services, such as Ahnlab, Inc., SECUi Corp. and Igloo Security, Inc.

Commerce Services

The commerce industry is evolving rapidly and is intensely competitive, and we face a broad array of competitors domestically and increasingly, internationally. Our marketplace business, 11st, faces intense competition from various e-commerce providers, including online open marketplaces and social commerce operators such as Coupang, Gmarket, Auction and Interpark. We also face competition from leading online and mobile search and communication platform companies with e-commerce operations, including NAVER and Kakao, as well as traditional retailers with online and mobile shopping portals such as SSG.com and Lotte.com, home shopping providers with online and mobile shopping portals such as CJ Mall by CJ O Shopping, GS Shop by GS Homeshopping and Hyundai Hmall by Hyundai Homeshopping, and various online marketplaces for specific consumer segments or product groups. Our T-commerce business, SK stoa, primarily competes with other home shopping providers such as those listed above, as well as with various e-commerce providers and traditional retailers.

Other Investments and Relationships

We have investments in several other businesses and companies and have entered into various business arrangements with other companies. Our principal investments include the following:

SK Hynix

As of December 31, 2020, we held a 20.1% equity interest in SK Hynix, one of the world’s largest memory-chip makers by revenue. SK Hynix designs, manufactures and sells advanced memory semiconductor products, including DRAM and NAND flash products, used in various electronic devices. SK Hynix operates four wafer fabrication facilities in Korea and China.

As of December 31, 2020, the fair value of our holding in SK Hynix was Won 17,312.9 billion. We received dividend payments of Won 146.1 billion in 2020, Won 219.2 billion in 2019 and Won 146.1 billion in 2018 related to such shareholding. In 2020, 2019 and 2018, SK Hynix and its subsidiaries, on a consolidated basis, reported revenues of Won 31,900.4 billion, Won 26,990.7 billion and Won 40,445.1 billion, respectively, profit before income tax of Won 6,237.0 billion, Won 2,432.6 billion and Won 21,341.0 billion, respectively, and profit for the year of Won 4,758.9 billion, Won 2,009.1 billion and Won 15,540.0 billion, respectively. The increase in SK Hynix’s revenues in 2020 was primarily due to increases in the demand for DRAM and NAND flash products, despite decreases in their average selling prices. As of December 31, 2020, 2019 and 2018, SK Hynix and its subsidiaries, on a consolidated basis, reported total assets of Won 71,173.9 billion, Won 65,248.4 billion and Won 63,658.3 billion, respectively, and total equity of Won 51,909.1 billion, Won 47,935.9 billion and Won 46,852.3 billion, respectively. For a more detailed discussion of the risks relating to our shareholding in SK Hynix, see “Item 3.D. Risk Factors — Risks Relating to Our Business — Declines in the market value of our equity holdings in SK Hynix and the results of operations of SK Hynix could have a material adverse effect on the market price of our common shares and ADSs as well as our results of operation.”

KEB HanaCard

In February 2010, we purchased shares newly issued by Hana SK Card Co., Ltd. (which was subsequently merged into KEB Card Co., Ltd. and renamed KEB HanaCard Co., Ltd. (“KEB HanaCard”) in November 2014), a credit card services provider, for a total purchase price of Won 400.0 billion. As of December 31, 2020, we held 15.0% of the total outstanding shares of KEB HanaCard. KEB HanaCard offers certain credit card products that provide for discounts on some of our wireless network services and integrate T Membership benefits, among other features.

Wavve

In September 2019, in furtherance of our efforts to enhance the competitiveness of our media business and to promote its future growth, we acquired a minority equity stake in Content Wavve (formerly known as Content Alliance Platform Inc.), a joint venture established by the three major terrestrial broadcasters in Korea that operated the mobile OTT service “POOQ,” by investing Won 90.9 billion in cash and transferring our former mobile OTT service business “oksusu” to Content Wavve. Content Wavve combined oksusu and POOQ to launch a new integrated mobile OTT service “wavve” in September 2019. As of December 31, 2020, we held 30.0% of the total outstanding shares of Content Wavve.

Wavve offers over 240,000 titles of video-on-demand contents, including a wide variety of real-time and on-demand terrestrial broadcast programs, movies, popular U.S. and other foreign TV shows and professional sporting events, to its subscribers that can be played on mobile devices, television, personal computer and/or Google’s Chromecast. Monthly subscription plans range from Won 7,900 to Won 13,900 per month, depending on the type and number of accessible devices. We also offer wavve-specific data add-on plans for our wireless service subscribers. Certain types of contents, such as movies, can also be purchased individually.

Law and Regulation

Overview

Korea’s telecommunications industry is subject to comprehensive regulation by the MSIT, which is responsible for information and telecommunications policies. The MSIT regulates and supervises a broad range of communications issues, including:

 

   

entry into the telecommunications industry;

 

   

scope of services provided by telecommunications service providers;

 

   

allocation of radio spectrum;

 

   

setting of technical standards and promotion of technical standardization;

 

   

rates, terms and practices of telecommunications service providers;

 

   

interconnection and revenue-sharing between telecommunications service providers;

 

   

research and development of policy formulation for information and telecommunications; and

 

   

competition among telecommunications service providers.

The MSIT is charged with regulating information and telecommunications and the KCC is charged with regulating the public interest aspects of and fairness in broadcasting.

Telecommunications service providers are currently classified into two categories: network service providers and value-added service providers. We are classified as a network service provider because we provide telecommunications services with our own telecommunications networks and related facilities. As a network service provider, we were previously required to obtain a license from the MSIT for the services we provide. However, an amendment to the Telecommunications Business Act, pursuant to which companies meeting certain regulatory criteria may become a network service provider without a separate license requirement, went into effect in June 2019. Our licenses permit us to provide cellular services, third generation wireless telecommunications services using WCDMA and WiBro technologies, fourth generation wireless telecommunications services using LTE technology and fifth generation wireless telecommunication services using 5G technology.

Table of Contents

The MSIT may revoke our licenses or suspend any of our businesses if we fail to comply with its rules, regulations and corrective orders, including the rules restricting beneficial ownership and control and corrective orders issued in connection with any violation of rules restricting beneficial ownership and control or any violation of the conditions of our licenses. Alternatively, in lieu of suspension of our business, the KCC may levy a monetary penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years. A network service provider that wants to cease its business or dissolve must notify its users 60 days prior to the scheduled date of cessation or dissolution and obtain MSIT approval.

In the past, the Government has stated that its policy was to promote competition in the Korean telecommunications market through measures designed to prevent the dominant service provider in any such market from exercising its market power in such a way as to prevent the emergence and development of viable competitors. While all network service providers are subject to MSIT regulation, we are subject to increased regulation because of our position as the dominant wireless telecommunications services provider in Korea.

Competition Regulation

The KCC is charged with ensuring that network service providers engage in fair competition and has broad powers to carry out this goal. If a network service provider is found to be in violation of the fair competition requirement, the KCC may take corrective measures it deems necessary, including, but not limited to, prohibiting further violations, requiring amendments to the articles of incorporation or to service contracts with customers, requiring the execution or performance of, or amendments to, interconnection agreements with other network service providers and prohibiting advertisements to solicit new subscribers. The KCC is required to take into account the opinion of the Minister of the MSIT before it takes certain corrective measures.

In addition, we qualify as a “market-dominating business entity” under the Fair Trade Act. Accordingly, we are prohibited from engaging in any act of abusing our position as a market-dominating entity, such as unreasonably determining, maintaining or altering service rates, unreasonably controlling the rendering of services, unreasonably interfering with business activities of other business entities, hindering unfairly the entry of newcomers or substantially restricting competition to the detriment of the interests of consumers.

Because we are a member company of the SK Group, which is a large business group as designated by the FTC, we are subject to the following restrictions under the Fair Trade Act:

 

   

Restriction on debt guarantee among affiliates.    Any affiliate within the SK Group may not guarantee the debts of another domestic affiliate, except for certain guarantees prescribed in the Fair Trade Act, such as those relating to the debts of a company acquired for purposes of industrial rationalization, bid deposits for overseas construction work or technology development funds.

 

   

Restriction on cross-investment.    A member company of the SK Group may not acquire or hold shares in an affiliate belonging to the SK Group that owns shares in the member company.

 

   

Restrictions on circular investments.    A member company of the SK Group may not acquire or hold shares which would constitute “circular investments” in an affiliate company which also forms part of the SK Group where “circular investments” refer to a cross-affiliate shareholding relationship under which three or more affiliate companies become connected through cross affiliate shareholdings by owning shares in other affiliates or by becoming an entity whose shares are owned by other affiliates.

 

   

Public notice of board resolution on large-scale transactions with specially related persons.    If a member company of the SK Group engages in a transaction with a specially related person in the amount of 5.0% or more of the member company’s capital or paid-in capital or for Won 5.0 billion or more, the transaction must be approved by a resolution of the member company’s board of directors and the member company must publicly disclose the transaction.

 

   

Restrictions on investments by subsidiaries and sub-subsidiaries of holding companies.    The Fair Trade Act prohibits subsidiaries of holding companies from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless such domestic affiliates are their own subsidiaries. Furthermore, any subsidiaries of a holding company’s subsidiaries (“sub-subsidiaries”) are

 

47


Table of Contents
 

prohibited from investing in, or holding shares of common stock of, domestic affiliates that belong to the same large business group, unless all shares issued by the affiliates are held by the sub-subsidiary. Therefore, we and other subsidiaries of SK Inc. may not invest in any domestic affiliate that is also a member company of the SK Group, except in the case where we invest in our own subsidiary or where another subsidiary of SK Inc. invests in its own subsidiary.

 

   

Public notice of the current status of a business group.    Under the Fair Trade Act and the Enforcement Decree thereof, a member company of the SK Group must publicly disclose the general status of the SK Group, including the name, business scope and financial status of affiliates, information on the officers of affiliates, information on shareholding and cross-investments between member companies of the SK Group, information on transactions with certain related persons and, if a member company engages in a transaction with an affiliated company in the amount of 5.0% or more of the member company’s quarterly sales or Won 5.0 billion or more, information on transactions with such affiliated company on a quarterly basis.

Rate Regulation

Network service providers whose sales proceeds exceed the amount prescribed by law must report to the MSIT the rates and contractual terms for each type of service they provide. Prior to December 2020, as the dominant network service provider for specific services (based on having the largest market share in terms of number of subscribers and meeting certain revenue thresholds), we had to obtain prior approval of the MSIT on our rates and terms of service; provided, however, that such pre-approval of the MSIT was not required to reduce the rates for any type of services provided under the MSIT-approved contractual terms. The MSIT’s policy was to approve rates if they were appropriate, fair and reasonable (that is, if the rates had been reasonably calculated, considering supply costs, profits, classification of costs and profits for each service, cost savings through changes in the way services were provided and the influence on fair competition, among others). The MSIT could order changes in the submitted rates if it deemed the rates to be significantly unreasonable or against public policy. In December 2020, however, the Telecommunications Business Act was amended to change such approval requirement to a reporting requirement. Under the new reporting requirement, which does not apply to other network service providers, the MSIT has fifteen days to object to any new rates and terms of service reported by us, and we may implement such new rates and terms of service after the fifteen-day period expires in the absence of the MSIT’s objection.

Furthermore, in 2007, the Government announced a “road map” highlighting revisions in regulations to promote deregulation of the telecommunications industry. In accordance with the road map and pursuant to the Combined Sales Regulation, promulgated in May 2007, telecommunications service providers are now permitted to bundle their services, such as wireless data transmission service, wireless voice transmission service, broadband Internet access service, fixed-line telephone service and IPTV service, at a discounted rate; provided, however, that we and KT, as market-dominating business entities under the Telecommunications Business Act, allow other competitors to employ the services provided by us and KT, respectively, so that such competitors can provide similar discounted package services. In September 2007, the regulations and provisions under the Telecommunications Business Act were amended to permit licensed transmission service providers to offer local, domestic long-distance and international telephone services, as well as broadband Internet access and Internet phone services, without additional business licenses.

Moreover, an MVNO system under which the MSIT may designate and obligate certain wireless telecommunications services providers to allow an MVNO, at such MVNO’s request, to use their telecommunication network facilities at a rate mutually agreed upon that complies with the standards set by the MSIT became effective on March 14, 2017 under the amended Telecommunications Business Act. We were designated as the only wireless telecommunications services provider obligated to allow the other wireless telecommunications services provider to use our telecommunications network facilities. The expiration of such system has been extended to September 22, 2022 pursuant to an amendment to the Telecommunications Business Act. Currently, 14 MVNOs provide wireless telecommunications services using the networks leased from us.

On October 1, 2014, the MDDIA, enacted for the purpose of establishing a transparent and fair mobile distribution practice, became effective. The MDDIA limits the amount of subsidies a wireless telecommunications service provider can provide to subscribers in order to prevent excessive competition among wireless

 

48


Table of Contents

telecommunications service providers. Pursuant to the MDDIA, wireless telecommunications service providers are prohibited from (i) unfairly providing discriminatory subsidies based on criteria such as type of subscription, subscription plan and characteristics of the subscriber and (ii) entering into a separate agreement with subscribers imposing obligations to use a specific subscription plan as a condition for providing subsidies. See “Item 5.A. Operating Results — Overview — Rate Regulations.”

In addition, under the MDDIA, wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving subsidies. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively. We cannot provide assurance that we will not provide other rate discounts in the future to comply with the Government’s public policy guidelines or suggestions.

Interconnection

Dominant network service providers such as ourselves that own essential infrastructure facilities or possess a certain market share are required to provide interconnection of their telecommunications network facilities to other service providers upon request. The MSIT sets and announces the standards for determining the scope, procedures, compensation and other terms and conditions of such provision, interconnection or co-use. We have entered into interconnection agreements with KT, LG U+ and other network service providers permitting these entities to interconnect with our network. We expect that we will be required to enter into additional agreements with new operators as the MSIT grants permits to additional telecommunications service providers.

Frequency Allocation

The MSIT has the discretion to allocate and adjust the frequency bandwidths for each type of service and may auction off the rights to certain frequency bandwidths. Upon allocation of new frequency bandwidths or adjustment of frequency bandwidths, the MSIT is required to give a public notice. The MSIT also regulates the frequency to be used by each radio station, including the transmission frequency used by equipment in our cell sites. All of our frequency allocations are for a definite term. We pay fees to the MSIT for our frequency usage that are determined based upon our number of subscribers, frequency usage by our networks and other factors. For 2020, 2019 and 2018, the fee amounted to Won 136.6 billion, Won 133.1 billion and Won 151.7 billion, respectively.

We currently use 10 MHz of bandwidth in the 2.1 GHz spectrum for our WCDMA services, 30 MHz of bandwidth in the 2.1 GHz spectrum, 20 MHz of bandwidth in the 800 MHz spectrum, 35 MHz of bandwidth in the 1.8 GHz spectrum and 60 MHz of bandwidth in the 2.6 GHz spectrum for our LTE services, as well as 100 MHz of bandwidth in the 3.5 GHz spectrum for our 5G services. We also plan to use 800 MHz of bandwidth in the 28 GHz spectrum for our 5G services in the future. In 2020, we recognized an impairment loss of Won 186.0 billion in connection with the frequency usage rights for the 800 MHz of bandwidth in the 28 GHz spectrum as the carrying amount exceeded the recoverable amount. For more information regarding the license fees for the various bandwidths that we use, see “Item 5.B. Liquidity and Capital Resources — Capital Requirements — Capital Expenditures” and note 17 of the notes to our consolidated financial statements.

In November 2020, the MSIT announced plans to reallocate a total of 310 MHz of frequency bandwidths whose usage terms are due to expire in 2021 to KT, LG U+ and us, 95 MHz of which will be allocated to us. The final consideration to be paid by us for such reallocated bandwidths will depend on the number of 5G cell sites constructed by us until 2022, and the aggregate consideration to be paid by KT, LG U+ and us is expected to range between approximately Won 3.2 trillion and Won 3.8 trillion.

For risks relating to the maintenance of adequate bandwidth capacity, see “Item 3.D. Risk Factors — Risks Relating to Our Business — Our business and results of operations may be adversely affected if we fail to acquire adequate additional frequency usage rights or use our bandwidth efficiently to accommodate subscriber growth and subscriber usage.”

Mandatory Contributions and Obligations

All telecommunications service providers other than value-added service providers and regional paging service providers or any telecommunications service providers whose net annual revenue is less than an amount determined by the MSIT (currently set at Won 30.0 billion) are required to provide “universal” telecommunications services including local telephone services, local public telephone services, telecommunications services for remote islands and wireless communication services for ships and telephone services for handicapped and low-income citizens, or contribute toward the supply of such universal services. The MSIT designates universal services and the service provider who is required to provide each service. Currently, under the MSIT guidelines, we are required to offer free subscription and a discount of between 30.0% to 50.0% of our monthly fee for wireless telecommunications services to handicapped and low-income citizens.

In addition to such universal services for handicapped and low-income citizens, we are also required to make certain annual monetary contributions to compensate for other service providers’ costs for the universal services. The size of a service provider’s contribution is based on its net annual revenue for the previous year (calculated pursuant to the MSIT guidelines, which differ from our accounting practices). We paid such contributions amounting to Won 17.4 billion, Won 16.1 billion and Won 16.7 billion in 2020, 2019 and 2018, respectively. As a wireless telecommunications services provider, we are not considered a provider of universal telecommunications services and do not receive funds for providing universal service. Other network service providers that do provide universal services make all or a portion of their “contribution” in the form of expenses related to the universal services they provide.

Foreign Ownership and Investment Restrictions and Requirements

Because we are a network service provider, and the exception for the foreign shareholding limit under the amended Telecommunications Business Act, which became effective on August 13, 2013, does not apply to us, foreign governments, individuals, and entities (including Korean entities that are deemed foreigners, as discussed below) are prohibited from owning more than 49.0% of our voting stock. Korean entities whose largest shareholder is a foreign government or a foreigner (together with any of its related parties) that owns 15.0% or more of the outstanding voting stock of such Korean entities are also deemed foreigners. If this 49.0% ownership limitation is violated, certain of our foreign shareholders will not be permitted to exercise voting rights in excess of the limitation, and the MSIT may require other corrective action.

As of December 31, 2020, SK Inc. owned 21,624,120 shares of our common stock, or 26.8% of our issued shares. As of December 31, 2020, the two largest foreign shareholders of SK Inc. each held a 3.9% stake therein. If such foreign shareholders increase their shareholdings in SK Inc. to 15% or more and any such foreign shareholder constitutes the largest shareholder of SK Inc., SK Inc. will be considered a foreign shareholder, and its shareholding in us would be included in the calculation of our aggregate foreign shareholding. If SK Inc.’s shareholding in us is included in the calculation of our aggregate foreign shareholding, then our aggregate foreign shareholding, assuming the foreign ownership level as of December 31, 2020 (which we believe was 33.4%), would reach 60.2%, exceeding the 49.0% ceiling on foreign shareholding.

If our aggregate foreign shareholding limit is exceeded, the MSIT may issue a corrective order to us, the breaching shareholder (including SK Inc. if the breach is caused by an increase in foreign ownership of SK Inc.) and the foreign shareholder which owns in the aggregate 15.0% or more of SK Inc. Furthermore, SK Inc. will be prohibited from exercising its voting rights with respect to the shares held in excess of the 49.0% ceiling, which may result in a change in control of us. In addition, the MSIT will be prohibited from granting us licenses or permits necessary for entering into new telecommunications businesses until our aggregate foreign shareholding is reduced to below 49.0%. If a corrective order is issued to us by the MSIT arising from the violation of the foregoing foreign ownership limit, and we do not comply within the prescribed period under such corrective order, the MSIT may:

 

   

revoke our business license;

 

   

suspend all or part of our business; or

 

   

if the suspension of business is deemed to result in significant inconvenience to our customers or to be detrimental to the public interest, impose a one-time administrative penalty of up to 3.0% of the average of our annual revenue for the preceding three fiscal years.

 

50


Table of Contents

Additionally, the Telecommunications Business Act also authorizes the MSIT to assess monetary penalties of up to 0.3% of the purchase price of the shares for each day the corrective order is not complied with, as well as a prison term of up to three years or a penalty of Won 150 million. See “Item 3.D. Risk Factors — Risks Relating to Our Business — If SK Inc. causes us to breach the foreign ownership limitations on our common shares, we may experience a change of control.”

We are required under the Foreign Exchange Transaction Act to file a report with a designated foreign exchange bank or with the MOEF, in connection with any issue of foreign currency denominated securities by us in foreign countries. Issuances of US$30 million or less require the filing of a report with a designated foreign exchange bank, and issuances that are over US$30 million in the aggregate within one year from the filing of a report with a designated foreign exchange bank require the filing of a report with the MOEF.

The Telecommunications Business Act provides for the creation of a Public Interest Review Committee under the MSIT to review investments in or changes in the control of network service providers. The following events would be subject to review by the Public Interest Review Committee:

 

   

the acquisition by an entity (and its related parties) of 15.0% or more of the equity of a network service provider;

 

   

a change in the largest shareholder of a network service provider;

 

   

agreements by a network service provider or its shareholders with foreign governments or parties regarding important business matters of such network service provider, such as the appointment of officers and directors and transfer of businesses; and

 

   

a change in the shareholder that actually controls a network service provider.

If the Public Interest Review Committee determines that any of the foregoing transactions or events would be detrimental to the public interest, then the MSIT may issue orders to stop the transaction, amend any agreements, suspend voting rights, or divest the shares of the relevant network service provider. Additionally, if a dominant network service provider (which would currently include us and KT), together with its specially related persons (as defined under the FSCMA), holds more than 5.0% of the equity of another dominant network service provider, the voting rights on the shares held in excess of the 5.0% limit may not be exercised.

Patents and Licensed Technology

Access to the latest relevant technology is critical to our ability to offer the most advanced wireless telecommunications services and to design and manufacture competitive products. In addition to active internal and external research and development efforts as described in “Item 5.C. Research and Development, Patents and Licenses, etc.,” our success depends in part on our ability to obtain patents, licenses and other intellectual property rights covering our products. We own numerous patents and trademarks worldwide, and have applications for patents pending in many countries. Our patents are mainly related to LTE and 5G technology and wireless Internet applications. We have also acquired a number of patents related to WCDMA and CDMA technologies. There are no licensed patents that are material to our business.

We are not currently involved in any material litigation regarding patent infringement. For a description of the risks associated with our reliance on intellectual property, see “Item 3.D. Risk Factors — Risks Relating to Our Business — Our business relies on technology developed by us, and our business will suffer if we are unable to protect our proprietary rights.”

Operating Results

Overview

Our operations are reported in five segments: (1) cellular services, which include wireless voice and data transmission services, sales of wireless devices, IoT solutions and platform services, (2) fixed-line telecommunication services, which include fixed-line telephone services, broadband Internet services, advanced media platform services (including IPTV and cable TV services) and business communications services, (3) security services, which include physical and information security services, (4) commerce services, which include our open marketplace platform, 11st, our T-commerce business, SK stoa, and related ancillary services, and (5) other businesses, which include our portal service, mobility business, marketing platform business and certain other miscellaneous businesses that do not meet the quantitative thresholds to be separately considered reportable segments.

In our cellular services segment, we earn revenue principally from our wireless voice and data transmission services through monthly plan-based fees, usage charges for outgoing voice calls, usage charges for wireless data services and value-added service fees paid by our wireless subscribers as well as interconnection fees paid to us by other telecommunications operators for use of our wireless network by their customers and subscribers. We also derive revenue from sales of wireless devices by PS&Marketing. Other sources of revenue include revenue from our IoT solutions and platform services, including AI solutions, as well as other miscellaneous cellular services.

In our fixed-line telecommunication services segment, we earn revenue principally from our fixed-line telephone services and broadband Internet services and advanced media platform services (including IPTV and cable TV services) through monthly plan-based fees and usage charges as well as interconnection fees paid to us by other telecommunications operators for use of our fixed-line network by their customers and subscribers. In addition, we derive revenue from international calling services and our business communications services through customized fee arrangements with our business customers. Following the Tbroad Merger in April 2020, the cable TV and broadband Internet services of the former Tbroad have become a part of our fixed-telecommunication services segment.

In our security services segment, we generate revenue from our physical and information security services businesses through our subsidiary ADT CAPS. Revenue from our physical security services is generated through monthly plan-based fees and usage charges for value-added services paid by subscribers. Revenue from our information security services is derived primarily through consideration paid by customers under contracts for our information security platform and consulting services and solutions. ADT CAPS (formerly known as SK Infosec) is the surviving entity resulting from the merger of LSH with and into SK Infosec in December 2020 and the merger of Former ADT CAPS with and into SK Infosec in March 2021. We had acquired Former ADT CAPS, which operated our physical security business prior to such mergers, in October 2018 and SK Infosec, which operated our information security business prior to the mergers, in December 2018. See “Item 3.D. Risk Factors — Risks Relating to Our Business — We may fail to successfully complete, integrate or realize the anticipated benefits of our new acquisitions, joint ventures or other strategic alternatives or corporate reorganizations, and such transactions may negatively impact our business.”

In our commerce services segment, we derive revenue from our subsidiaries Eleven Street, which was spun-off as our new consolidated subsidiary from SK Planet in September 2018, and SK Stoa. Eleven Street generates revenue principally through third-party seller fees earned (including commissions) for transactions in which it acts as a selling agent to the “mini malls” on 11st, its online open marketplace platform, as well as advertising revenue and other commerce solutions from 11st. SK Stoa derives revenues through third-party seller fees earned (including commissions) for transactions in which it acts as a selling agent on SK stoa, its T-commerce network.

In our others segment, we earn revenue from the marketing platform business of SK Planet, the music streaming service and audio device manufacturing businesses of Dreamus, the mobility business of T Map Mobility and our “Nate” portal service operated by our subsidiary, SK Communications.

Following the spin-off of SK Telecom’s mobility business into T Map Mobility effective as of December 29, 2020, our mobility business, which was previously part of our cellular services segment, became a part of our others segment beginning on December 29, 2020.

Furthermore, following the entry into an agreement to transfer SK Broadband’s 100% equity interest in SK Stoa to SK Telecom in April 2019 (which transaction was completed in January 2020), the T-commerce business operations of SK Stoa, which were previously part of our fixed-line telecommunication services segment in the year ended December 31, 2018, were reclassified as part of our commerce services segment for the year ended December 31, 2019. In addition, our security services businesses, which were previously part of our others segment in the year ended December 31, 2018, were reclassified as a new security services segment for the year ended December 31, 2019. The breakdown of our results of operations by operating segment for the year ended December 31, 2018 in our consolidated audited financial statements have been recast to retroactively apply such changes in segmentation.

Our cellular service revenue and fixed-line telecommunications service revenue depend principally upon the number of our subscribers, the rates we charge for our services, the frequency and volume of subscriber usage of our services and the terms of our interconnection with other telecommunications operators. Our security service revenue depends principally upon the number of our subscribers and customers and the rates we charge for our physical security services as well as the number and terms of the contracts pursuant to which our information security services are provided. Our commerce service revenue depends principally upon the gross merchandise volume, which is the total monetary value of customer purchases of goods and services, net of estimated refunds, of 11st and SK stoa and the number of merchants that utilize 11st and SK stoa to advertise and promote their products and services and the extent of such advertisement and promotion.

Among other factors, management uses operating profit of each reportable segment presented in accordance with K-IFRS (“segment operating profit”) in its assessment of the profitability of each reportable segment. The sum of segment operating profit for all five reportable segments differs from our operating profit presented in accordance with IFRS as issued by the IASB as segment operating profit does not include certain items such as donations, gain and loss from disposal of property and equipment and intangible assets and impairment loss on property and equipment and intangible assets. For a reconciliation of operating profit presented in accordance with IFRS as issued by the IASB and operating profit presented in accordance with K-IFRS, see “— Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS.” In addition to the information set forth below, see note 5 of the notes to our consolidated financial statements for more detailed information regarding each of our reportable segments.

A number of recent developments have had or are expected to have a material impact on our results of operations, financial condition and capital expenditures. These developments include:

Rate Regulations.    Under the MDDIA, wireless telecommunications service providers are obliged to provide certain benefits, such as discounted rates, to subscribers who subscribe to their service without receiving handset subsidies. Handset subsidies are provided to subscribers who agree to use our service for a predetermined service period and purchase handsets on an installment basis. In June 2017, the State Affairs Planning Advisory Committee of Korea announced that it would encourage wireless telecommunications service providers, including us, to increase the applicable discount rate offered to subscribers from 20% to 25%, which we adopted in September 2017, and to offer additional discounts to low income customers, including those on government welfare programs and senior citizen recipients of the basic pension, which we implemented in December 2017 and July 2018, respectively.

In 2020, the total number of subscribers who had elected to receive discounted rates in lieu of receiving handset subsidies pursuant to the MDDIA increased due to greater public awareness of the availability of such discounted rates as well as the increase in the applicable discount rate to 25%. In 2020, approximately 71% of our new subscribers elected to receive discounted rates in lieu of handset subsidies compared to 55% in 2019. As of December 31, 2020, a substantial majority of our subscribers who elected to receive these discounted rates are receiving the increased 25% rate discount. These Government measures have adversely affected our revenues and results of operations as more subscribers elected to receive the 25% rate discount. On the other hand, this has also led to a reduction of, or partially offset increases in, our marketing expenses as the number of subscribers who have elected to receive handset subsidies has declined, and has contributed to maintaining a stable churn rate.

Failure to comply with the MDDIA may lead to suspension of our business or imposition of monetary penalties. For more information about the MDDIA and the penalties imposed for violating Government regulations, see “Item 4.B. Business Overview — Law and Regulation — Rate Regulation” and “Item 8.A. Consolidated Statements and Other Financial Information — Legal Proceedings — KCC Proceedings.”

Decrease in Interconnection Fees.    Our wireless telecommunications services depend, in part, on our interconnection arrangements with domestic and international fixed-line and other wireless networks. Charges for interconnection affect our revenues and operating results. The MSIT determines the basic framework for interconnection arrangements, including policies relating to interconnection rates in Korea. Under our interconnection agreements, we are required to make payments in respect of calls which originate from our networks and terminate in the networks of other Korean telecommunications operators, and the other operators are required to make payments to us in respect of calls which originate in their networks and terminate in our network. The MSIT has continued to gradually decrease the interconnection rates in Korea, which has led to a continued decrease in our interconnection revenue as well as interconnection expenses from 2012 to 2020 and any further reduction in interconnection rates by the MSIT may continue to impact our results of operations. Beginning in 2017, a single interconnection rate paid by fixed-line network service providers for fixed-line to wireless calls applies to all wireless telecommunications service providers. For more information about our interconnection revenue and expenses, see “Item 4.B. Business Overview — Interconnection.”

Decrease in Monthly Revenue per Subscriber.    We measure monthly average revenue per subscriber using two metrics: average monthly revenue per subscriber excluding MVNO subscribers leasing our networks (“ARPU”) and average monthly revenue per subscriber including such MVNO subscribers (“ARPU including MVNO”). ARPU is derived by dividing the sum of total SK Telecom revenues on a separate basis from voice service and data service for the period (excluding revenue derived from MVNO subscribers leasing our networks) by the monthly average number of subscribers (excluding the number of MVNO subscribers) for the period, then dividing that number by the number of months in the period. ARPU including MVNO is derived by dividing the sum of total SK Telecom revenues on a separate basis from voice service and data service for the period (including revenue derived from MVNO subscribers) by the monthly average number of subscribers (including the number of MVNO subscribers) for the period, then dividing that number by the number of months in the period.

Our ARPU decreased by 1.0% to Won 30,314 in 2020 from Won 30,630 in 2019, which represented a decrease of 5.0% from Won 32,247 in 2018. Our ARPU including MVNO increased by 1.8% to Won 27,895 in 2020 from Won 27,412 in 2019, which represented a decrease of 4.2% from Won 28,615 in 2018. The decreases in ARPU and ARPU including MVNO in 2019 were primarily due to a decrease in revenue attributable to an increase in the number of subscribers who elected to receive discounted rates in lieu of receiving handset subsidies. The decrease in ARPU in 2020 was primarily due to an increase in subscriptions for IoT solutions by corporate customers, from which we derive lower revenue per subscriber. Such decreases were offset in part by an increase in subscribers that subscribe to our higher-priced unlimited data usage plans and 5G plans. The increase in ARPU including MVNO in 2020 was primarily attributable to the decrease in the proportion of MVNO subscribers, from whom we derive lower revenue per subscriber.

Effects of COVID-19.    Demand for our products and services may fluctuate in light of the overall economic conditions in Korea. The overall prospects for the Korean economy and, in turn, the market conditions for the industries in which we operate, remain uncertain, especially in light of the ongoing global COVID-19 pandemic, which has had, will likely continue to have, a significant negative effect on the Korean economy. For example, the travel restrictions imposed by governments in response to the COVID-19 pandemic has resulted in a decrease in revenue from roaming services, and the pandemic has contributed to lower customer demand for new wireless devices, resulting in a decrease in our wireless device sales revenue. In addition, an increase in unemployment among, and/or a decrease in disposable income of, our customers resulting from a deterioration of the Korean economy due to COVID-19 may decrease demand for some of our products and services or cause an increase in delinquent subscriber accounts. While it is not possible to predict the duration or full magnitude of harm from COVID-19, a continued and prolonged outbreak of COVID-19 may have a material adverse effect on our business, financial condition and results of operations. See “Item 3.D. Risk Factors—Risks Relating to Our Business — The ongoing global pandemic of COVID-19 and any possible recurrence of other types of widespread infectious diseases may adversely affect our business, financial condition or results of operations.”

Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS

In addition to preparing consolidated financial statements in accordance with IFRS as issued by the IASB included in this annual report, we also prepare financial statements in accordance with K-IFRS as adopted by the KASB, which we are required to file with the FSC and the Korea Exchange under the FSCMA.

K-IFRS requires operating profit, which is calculated as operating revenue less operating expense, to be separately presented on the consolidated statement of income. The presentation of operating profit in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB included in this annual report differs from the presentation of operating profit in the consolidated statements of income prepared in accordance with K-IFRS for the corresponding periods in certain respects. The table below sets forth a reconciliation of our operating profit as presented in our consolidated statements of income prepared in accordance with IFRS as issued by the IASB for each of the three years ended December 31, 2020 to the operating profit as presented in the consolidated statements of income prepared in accordance with K-IFRS.

Critical Accounting Policies, Estimates And Judgments

Our consolidated financial statements are prepared in accordance with IFRS as issued by the IASB. The preparation of the consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue and expenses as well as the disclosure of contingent assets and liabilities. We continually evaluate our estimates and judgments including those related to loss allowances, fair value measurements of financial instruments, estimated useful lives and impairment of long-lived assets, impairment of goodwill, provisions, retirement benefit plans and income taxes. We base our estimates and judgments on historical experience and other factors that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. We believe that of our significant accounting policies, the following may involve a higher degree of judgment or complexity:

Loss Allowances

A loss allowance is provided based on a review of the status of individual receivable accounts at the end of the year. We maintain loss allowances for estimated losses that result from the inability of our customers to make required payments. We base our allowances on the likelihood of recoverability of accounts receivable based on the aging of accounts receivable at the end of the period, past customer default experience and their credit status, and economic and industrial factors. In addition, we use an “expected credit loss” impairment model to estimate our loss allowances based on the above-described criteria. Under such model, loss allowances are recorded prior to experiencing delinquency on our receivable accounts rather than upon actual delinquency. Loss allowance

amounted to Won 365.1 billion as of December 31, 2020 and Won 346.4 billion as of December 31, 2019. If economic or specific industry trends worsen beyond our estimates, the loss allowances we have recorded may be materially adjusted in the future. See note 7 of the notes to our consolidated financial statements.

Fair Value Measurement of Financial Instruments

Subsequent to initial recognition, financial assets at fair value through profit or loss, financial assets at fair value through other comprehensive income and derivative financial assets are stated at fair value with any gains or losses arising on remeasurement recognized in profit for the period or other comprehensive income. When measuring fair value, we use quoted prices in active markets to the extent such prices exist. The fair values of financial instruments, including derivative instruments, that are not traded in an active market are determined using valuation techniques that require management’s estimates of future cash flows and discount rates. Our management uses its judgment to select a variety of methods and makes assumptions that are mainly based on market conditions existing at the end of each reporting period. See notes 2(4) and 36(3) of the notes to our consolidated financial statements.

Impairment of Long-lived Assets Including Frequency Usage Rights

Long-lived assets generally consist of property and equipment and definite-lived intangible assets. We review our depreciation and amortization methods, estimated useful lives and residual values of long-lived assets at the end of each annual reporting period. If any such asset or cash-generating unit is considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount of the asset or cash-generating unit exceeds the estimated recoverable amount. The recoverable amount of a long-lived asset is the greater of an asset’s fair value less costs to sell and its value in use. For the purpose of assessing impairment, we review the recoverable amount of an individual asset or, if it is not possible to measure the individual recoverable amount of an asset, at the level of a cash-generating unit. The recoverable amounts of assets or cash-generating units may be determined based on value-in-use calculations, which require the use of estimates.

Our definite-lived intangible assets include our frequency usage rights, which have contractual lives of 5 to 10.25 years and are amortized from the date commercial service is initiated through the end of their contractual lives. Because the use of frequency usage rights is exposed to risks and challenges associated with our business, any or all of which, if realized or not properly addressed, may have a material adverse effect on our financial condition, results of operations and cash flows, we review the frequency usage rights for any indication of impairment on an annual basis. If any such indication exists, we test for impairment utilizing the estimated long-term revenue and cash flow forecasts. The use of different assumptions within our cash flow model could result in different recoverable amounts for our frequency usage rights. The results of our review using the testing method described above resulted in an impairment loss in the amount of Won 198.4 billion of our frequency usage rights in 2020. See note 17 of the notes to our consolidated financial statements.

Impairment of Goodwill

Goodwill is measured as the excess of the sum of: (1) the consideration transferred, (2) the amount of any non-controlling interests in the acquiree and (3) the fair value of the acquirer’s previously held equity interest in the acquiree (if any), over the net fair value of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. Goodwill is not amortized, but tested for impairment at the end of each annual reporting period or whenever there is an indication that the asset may be impaired. Goodwill is carried at cost less accumulated impairment losses and the impairment losses are not reversed. For the purpose of impairment testing, we review the recoverable amount of an individual asset or, if it is not possible to measure the individual recoverable amount of an asset, at the level of a cash-generating unit. The recoverable amount of an asset or cash-generating unit to which goodwill has been allocated is the greater of its value in use and its fair value less costs to sell. The value in use calculation requires our management to estimate the future cash flows expected related to the respective cash-generating unit and the determination of an appropriate discount rate in order to calculate present value.

In 2020, we recognized Won 0.5 billion of impairment losses on goodwill compared to Won 21.1 billion of impairment losses on goodwill in 2019. Impairment losses on goodwill in 2020 were mainly due to our recognition

 

57


Table of Contents

of impairment losses on goodwill relating to our consolidated subsidiaries Dreamus and Incross. Impairment losses on goodwill in 2019 were mainly due to our recognition of impairment losses on goodwill relating to our consolidated subsidiary Life Design Company Inc. (“Life Design Company”), which operates a celebrity-related merchandise business in Japan.

As of December 31, 2020, the amount of goodwill allocated to our security services cash-generating unit, which is primarily derived from the acquisition of LSH, was Won 1,176.3 billion, which increased slightly from Won 1,173.4 billion as of December 31, 2019. Our management calculated the recoverable amount of such cash-generating unit based on its value in use using a discounted cash flow method. The discounted cash flow method was based on certain key assumptions with respect to relevant revenue growth rates, labor costs, perpetual growth rate and cash flow discount rate that were primarily derived from internal sources as well as historical performance, external market data and industry reports. The estimated revenue growth rates and labor costs were based on 5-year financial budgets that have been approved by management, which took into account external market data, market trends and expectations as well as historical performance. Cash flows beyond 2025 were projected to grow at a perpetual growth rate estimated at 1.0%. Estimating a perpetual growth rate requires significant management judgment about future business strategies as well as micro- and macro-economic environments that are inherently uncertain. Our 5-year cash flow projections with a terminal value were discounted at an appropriate weighted average cost of capital to 7.1%. Based on such calculation, the recoverable amount of the cash-generating unit exceeded its carrying amount, and no impairment loss was recognized on such goodwill in 2020. Future changes in one or more of such assumptions may cause the carrying amount of the cash-generating unit to exceed its recoverable amount, which would require us to recognize impairment losses on goodwill relating to such cash-generating unit as discussed in note 16(2) of the notes to our consolidated financial statements.

See notes 4(11) and 16 of the notes to our consolidated financial statements.

Income Taxes

We are required to estimate the amount of tax payable or refundable for the current year and the deferred income tax liabilities and assets for the future tax consequences of events that have been reflected in our financial statements or tax returns. This process requires management to make assessments regarding the timing and probability of the tax impact. Actual income taxes could vary from these estimates due to future changes in income tax law or unpredicted results from the final determination of each year’s liability by taxing authorities. We believe that the accounting estimate related to assessment of deferred tax assets for recoverability is a “critical accounting estimate” because (1) it requires management to make assessments about the timing of future events, including the probability of expected future taxable income and available tax planning opportunities and (2) the impact that changes in actual performance versus these estimates could have on the realization of tax benefits as reported in our results of operations could be material. Management’s assumptions require significant judgment because actual performance has fluctuated in the past and may continue to do so. As of December 31, 2020 and 2019, unused tax loss carryforwards of Won 1,042.1 billion and Won 1,023.9 billion, respectively, were not recognized as deferred tax assets because we did not believe that their realization would be probable. The increase of Won 18.2 billion in unrecognized tax loss carryforwards in 2020 compared to 2019 was primarily related to an increase in unrecognized tax loss carryforwards of SK Planet. See notes 4(24) and 32 of the notes to our consolidated financial statements.

Prepaid Expenses

We pay commissions to our retail stores and authorized dealers in connection with acquiring wireless and fixed-line telecommunications subscriber contracts, which would not have been paid if there were no binding contracts with subscribers. We capitalize certain costs associated with such commissions as prepaid expenses and amortize them over the expected periods over which we expect to maintain such subscribers under contract. Our management assesses such expected contract periods based on our historical experience on the duration of subscriber contracts. If we experience any changes in such historical experience, or if our management decides to use other factors for the determination of the expected contract periods, our estimate of the expected contract period will change, which in turn will affect the rate at which the applicable prepaid expenses are amortized and recognized as our operating expenses. See note 8 of the notes to our consolidated financial statements.

Determination of Stand-Alone Selling Prices in Recognition of Revenue from Cellular Services

For contracts where we sell both a wireless device and subscription plan together to a single customer through our subsidiary PS&Marketing, we allocate revenue proportionately based on the relative stand-alone selling prices of the subscription plan and the device, and we recognize unbilled receivables from wireless device sales as contract assets. See note 9 of the notes to our consolidated financial statements. In determining the stand-alone selling price for the subscription plan, we apply the published price of such subscription plan net of any applicable rate discounts, based on our management’s judgment that such discounted price represents the appropriate stand-alone selling price of such plan. A significant change in the facts and circumstances upon which we made such judgment on the determination of stand-alone selling prices may have an impact on the allocation of revenues from our cellular services segment.

Determination of Lease Term

Under IFRS 16, we determine lease terms by including periods covered by an option to extend the lease if the lessee is reasonably certain to exercise such option and periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise such option. Such determination requires us to assess the likelihood that the lessee will exercise such options, which assessment in turn is made in consideration of whether the lessee would incur a penalty on termination that is more than insignificant. See “— Recently Adopted International Financial Reporting Standards - IFRS 16.”

Based on such assessments, we have concluded that it is reasonably certain that the underlying lease assets or related assets will generally be used by the lessee for the period of their useful lives, and we determine the lease terms of such assets based on such useful lives. For example, in the case of circuits that are part of telecommunication equipment that are leased by us, we have determined their lease term to be eight years based on the useful life of such circuits. In the case of real estate leased by us to install network equipment, we have determined their lease term to be eight years in the case of those related to 5G services and six years for other networks based on their respective useful lives.

Customer Relationship

In connection with the Tbroad Merger, we recognized the acquired customer relationships arising from the business combination as an identifiable intangible asset in 2020. The fair value of such customer relationships amounted to Won 374.0 billion as of April 30, 2020, the acquisition date. The fair value was estimated based on the multi-period excess earnings method (“MPEEM”), which is a valuation technique under the income approach that estimates fair value by discounting the expected future excess earnings attributable to an intangible asset using a risk-adjusted discount rate. The MPEEM uses significant unobservable inputs including estimated revenue per subscriber, future churn rate and weighted average cost of capital, which require a significant degree of judgment by our management. See note 12 of the notes to our consolidated financial statements.

Recently Adopted International Financial Reporting Standards – IFRS 16

We adopted IFRS 16, Leases, in the fiscal year beginning on January 1, 2019 using the modified retrospective method by recognizing the cumulative effect of initially applying IFRS 16 as an adjustment to the opening balance of retained earnings as of such date. IFRS 16 introduces a single, on-balance sheet accounting model for lessees. Pursuant to IFRS 16, we recognize right-of-use assets representing our rights to use the underlying assets and lease liabilities representing our obligation to make lease payments in relation to substantially all of our lease arrangements, except for certain short-term leases and leases of low-value assets. Lessor accounting remains similar to previous accounting policies.

In the fiscal year beginning on January 1, 2020, we changed our accounting policy by applying the agenda decision, Lease Term and Useful Life of Leasehold Improvements (IFRS 16 Leases and IAS 16 Property, Plant and Equipment)—November 2019, published by the IFRIC on December 16, 2019. Prior to such change in accounting policy, we determined a lease term based on the assumption that the right to extend or terminate the lease is no longer enforceable if the lease contract requires the counterparty’s consent to be extended. Under the new accounting policy, we determine the lease term based on the non-cancellable period of a lease in addition to

Table of Contents

(i) periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option and (ii) periods covered by an option to terminate the lease if the lessee is reasonably certain not to exercise that option. In assessing the periods covered by an option to extend the lease if the lessee is reasonably certain to exercise that option, we consider whether we would incur a penalty on termination that is more than insignificant. We have retrospectively applied such change in accounting policy in connection with the IFRIC agenda decision and restated our consolidated financial statements as of January 1, 2019 and as of and for the year ended December 31, 2019.

The change in accounting policy had the effect of increasing our total assets and total liabilities as of December 31, 2019 by Won 590.7 billion and Won 597.4 billion, respectively. In the case of our consolidated statement of income for the year ended December 31, 2019, the change had the effect of decreasing our operating revenue and other income by Won 3.4 billion and decreasing operating expenses by Won 9.8 billion, resulting in an increase in operating profit by Won 6.4 billion and a decrease in profit before income tax by Won 1.7 billion. In addition, the change had the effect of decreasing our profit for the year by Won 1.2 billion and decreasing our income tax expense by Won 0.4 billion. In the case of our consolidated statement of cash flows for the year ended December 31, 2019, the change had the effect of increasing cash flows from operating activities by Won 48.9 billion, increasing cash flows from investing activities by Won 0.9 billion and decreasing cash flows from financing activities by Won 49.8 billion.

See notes 3 and 4(12) of the notes to our consolidated financial statements for further details regarding the effects of the change in accounting policy based on the IFRIC agenda decision and significant accounting policies related to leases.

(3)

Broadband internet service and advanced media platform service revenue includes revenues from our broadband Internet services as well as IPTV and cable TV services.

 

(4)

Miscellaneous fixed-line telecommunication services revenue includes revenues from business communications services (other than fixed-line telephone service) provided by SK Broadband and VoIP services provided by SK Telink. Following the entry into an agreement to transfer SK Broadband’s 100% equity interest in SK Stoa to SK Telecom in April 2019 (which transaction was completed in January 2020), the T-commerce business operations of SK Stoa, which were previously part of our fixed-line telecommunications services segment in the year ended December 31, 2018, were reclassified as part of our commerce services segment for the year ended December 31, 2019. As a result, our results of operations for the year ended December 31, 2018 have been restated to retroactively apply such reclassification.

 

(5)

Security services revenue includes revenues from our former subsidiaries Former ADT CAPS and SK Infosec. Such revenues, which were previously part of our others segment in the year ended December 31, 2018, were separated into a new security services segment for the year ended December 31, 2019. As a result, our results of operations for the year ended December 31, 2018 have been restated to retroactively apply such new segmentation. We have subsequently combined LSH, Former ADT CAPS and SK Infosec into a single entity through a series of mergers that were completed in March 2021, and the combined entity, ADT CAPS, has become the principal consolidated subsidiary that operates our security business.

 

(6)

Commerce services revenue includes revenues from Eleven Street and SK Stoa.

 

(7)

Others revenue includes revenues from the marketing platform business operations of SK Planet, “Nate,” our online portal service operated by SK Communications, and other businesses. As a result of the spin-off of T Map Mobility, our mobility business, which was previously part of our cellular services segment, became a part of our other businesses segment beginning December 29, 2020.

“Segment operating expense” means operating expense for each reportable segment presented in accordance with K-IFRS and therefore does not include certain expenses that are classified as other non-operating expenses under K-IFRS. For more information on the differences between our consolidated operating expense pursuant to K-IFRS and pursuant to IFRS as issued by the IASB, see “— Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS.”

2020 Compared to 2019

Operating Revenue and Other Income.    Our consolidated operating revenue and other income increased by 4.9% to Won 18,724.3 billion in 2020 from Won 17,843.5 billion in 2019 due to an increase in operating revenue, which was in small part offset by a decrease in other income, as discussed below.

Our consolidated operating revenue increased by 5.0% to Won 18,624.7 billion in 2020 from Won 17,740.7 billion in 2019, primarily due to increases in fixed-line telecommunications services revenue, security services revenue and cellular services revenue, and to a smaller extent, increases in commerce services revenue and others revenue.

Our consolidated other income decreased by 3.1% to Won 99.6 billion in 2020 from Won 102.8 billion in 2019, primarily due to a decrease in gain on business transfer in 2020 as compared to 2019. Such gain on business transfer in 2020 was mainly related to the transfer of the digital disease management business of Health Connect Co., Ltd. to Invites Healthcare Co., Ltd., while the gain in 2019 was mainly related to the transfer of our e-sports business to SK Telecom CS T1 Co., Ltd., a joint venture with Comcast Spectacor that was newly established in February 2019, as well as the transfer of our former mobile OTT service business, “oksusu,” to Content Wavve in September 2019.

The following sets forth additional information about our operating revenues with respect to each of our reportable segments.

 

   

Cellular services: The revenue of our cellular services segment, which is composed of revenues from wireless service, cellular interconnection, wireless device sales and miscellaneous cellular services, increased by 1.0% to Won 12,295.7 billion in 2020 from Won 12,177.5 billion in 2019. The increase in our cellular services revenue was due to an increase in wireless service revenue, partially offset by decreases in miscellaneous revenue, wireless device sales revenue and cellular interconnection revenue.

Table of Contents
   

Wireless service revenue increased by 2.8% to Won 9,801.2 billion in 2020 from Won 9,532.4 billion in 2019, primarily attributable to the increase in the number of subscribers who subscribe to our higher-priced 5G plans. The impact of such increase was partially offset by an increase in the percentage of wireless service subscribers who elected to receive discounted rates in lieu of receiving handset subsidies pursuant to the MDDIA as well as a decrease in MNVO subscribers.

 

   

Miscellaneous cellular services revenue decreased by 6.4% to Won 1,047.0 billion in 2020 from Won 1,118.8 billion in 2019, primarily due to the termination of certain social commerce businesses in 2020.

 

   

Wireless device sales revenue decreased by 5.5% to Won 975.2 billion in 2020 from Won 1,032.1 billion in 2019, primarily due to a decrease in sales of handsets as a result of lower customer demand for new devices, which was partly attributable to the COVID-19 pandemic.

 

   

Cellular interconnection revenue decreased by 4.5% to Won 472.3 billion in 2020 from Won 494.3 billion in 2019. The decrease was primarily attributable to continued decreases in interconnection rates and land-to-mobile call volume.

 

   

Fixed-line telecommunications services: The revenue of our fixed-line telecommunication services segment, which is composed of revenues from broadband Internet service and advanced media platform service (including IPTV and cable TV services), fixed-line telephone service, international calling service, fixed-line interconnection and miscellaneous fixed-line telecommunication services, increased by 15.8% to Won 3,405.7 billion in 2020 from Won 2,940.1 billion in 2019, primarily due to increases in our broadband Internet service and advanced media platform service revenue and miscellaneous fixed-line telecommunication services revenue, partially offset by decreases in fixed-line telephone service revenue and fixed-line interconnection revenue.

 

   

Revenue from our broadband Internet service and advanced media platform service (including our IPTV and cable TV services) increased by 23.2% to Won 2,227.1 billion in 2020 from Won 1,807.5 billion in 2019, primarily due to the inclusion of revenue of the former Tbroad following the Tbroad Merger as well as an increase in the number of IPTV subscribers to 5.7 million subscribers as of December 31, 2020 from 5.2 million subscribers as of December 31, 2019.

 

   

Miscellaneous fixed-line telecommunication services revenue increased by 5.8% to Won 717.4 billion in 2020 from Won 677.8 billion in 2019, primarily due to an increase in revenue from our business communications services.

 

   

Fixed-line telephone service revenue decreased by 3.9% to Won 215.8 billion in 2020 from Won 224.5 billion in 2019, primarily due to decreases in the number of fixed-line telephone subscribers (including subscribers to VoIP services of SK Broadband and SK Telink) to 3.8 million as of December 31, 2020 from 3.9 million as of December 31, 2019 and residential calling volume as a result of shifting consumer preferences toward wireless communication.

 

   

Fixed-line interconnection revenue decreased by 7.8% to Won 85.1 billion in 2020 from Won 92.3 billion in 2019, primarily due to a decrease in interconnection rates, as well as decreases in the number of fixed-line telephone subscribers and residential calling volume as described above.

 

   

Security services: The revenue of our security services segment, which is composed of revenues from our former subsidiaries Former ADT CAPS and SK Infosec (prior to its merger with Former ADT CAPS), increased by 12.3% to Won 1,246.5 billion in 2020 from Won 1,109.5 billion in 2019, primarily due to an increase in the number of subscribers to our CMS products as well as our acquisition of the security equipment construction and security services business of SK hystec inc. in July 2020.

 

   

Commerce services: The revenue of our commerce services segment, which is composed of revenues from 11st, our open marketplace platform, and SK stoa, our T-commerce network, increased by 11.6% to

Table of Contents
 

Won 792.9 billion in 2020 from Won 710.7 billion in 2019, primarily due to the expansion of the customer base and product sourcing capabilities of our SK stoa business as well as the growth in general merchandise volume of 11st.

 

   

Others: The revenue of our others segment increased by 10.1% to Won 883.9 billion in 2020 from Won 803.0 billion in 2019, primarily due to increases in revenue of FSK L&S and One Store Co., Ltd.

Operating Expense.    Our consolidated operating expense increased by 4.7% to Won 17,619.7 billion in 2020 from Won 16,836.2 billion in 2019, primarily due to a 6.9% increase in commissions to Won 5,347.1 billion in 2020 from Won 5,002.1 billion in 2019, a 16.3% increase in other operating expenses to Won 1,996.4 billion in 2020 to Won 1,716.4 billion in 2019, a 6.5% increase in labor costs to Won 3,006.2 billion from Won 2,822.7 billion in 2019 and a 3.5% increase in depreciation and amortization expenses to Won 3,991.1 billion in 2020 from Won 3,856.7 billion in 2019, partially offset by a 12.3% decrease in cost of goods sold to Won 1,608.5 billion in 2020 from Won 1,833.4 billion in 2019.

The increase in commissions was primarily due to the inclusion of commissions of the former Tbroad following the Tbroad Merger.

The increase in other operating expenses was primarily due to an increase in impairment loss on property and equipment and intangible assets to Won 208.8 billion in 2020 from Won 65.9 billion in 2019, which amount in 2020 mainly reflected impairment losses we recognized on frequency usage rights.

The increase in labor costs was primarily due to the additional personnel on payroll in connection with the Tbroad Merger as well as the expansion of our security and commerce businesses.

The increase in depreciation and amortization expenses was primarily related to our equipment and frequency usage rights for our 5G network.

The decrease in cost of goods sold was primarily due to a decrease in the number of wireless devices sold in 2020.

The following sets forth additional information about our segment operating expense with respect to each of our reportable segments, which do not include certain expenses that are classified as other non-operating expenses under K-IFRS. For more information on the difference between our consolidated operating expense pursuant to K-IFRS and pursuant to IFRS as issued by the IASB, see “ — Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS” and note 5(2) of the notes to our consolidated financial statements.

 

   

Cellular services: The segment operating expense for our cellular services segment increased by 0.2% to Won 11,287.8 billion in 2020 from Won 11,261.7 billion in 2019, mainly attributable to an increase in marketing costs to promote our 5G services and increases in depreciation and amortization expenses of our equipment and frequency usage rights for our 5G network.

 

   

Fixed-line telecommunication services: The segment operating expense for our fixed-line telecommunication services segment increased by 12.7% to Won 3,161.6 billion in 2020 from Won 2,804.4 billion in 2019, primarily due to the inclusion of operating expenses of the former Tbroad following the Tbroad Merger.

 

   

Security services: The segment operating expense for our security services segment increased by 16.2% to Won 1,134.1 billion in 2020 from Won 975.9 billion in 2019, primarily due to an increase in expenses related to the launch of new security services in 2020.

 

   

Commerce services: The segment operating expense for our commerce services segment increased by 10.3% to Won 781.9 billion in 2020 from Won 708.7 billion in 2019, primarily due to increases in marketing expenses as well as commissions associated with the increase in general merchandise volume of our 11st business.

 

   

Others: The segment operating expense for our others segment increased by 3.2% to Won 909.9 billion in 2020 from Won 881.9 billion in 2019, primarily due to an increase in operating expense of FSK L&S.

Operating Profit.    Our consolidated operating profit increased by 9.7% to Won 1,104.6 billion in 2020 from Won 1,007.3 billion in 2019, as the increase in operating revenue and other income outpaced the increase in operating expense in 2020.

The following sets forth additional information about our segment operating profit with respect to each of our reportable segments. Our segment operating profit with respect to each of our reportable segments is based on K-IFRS and the sum of segment operating profit for all five reportable segments differs from our consolidated operating profit presented in accordance with IFRS as issued by the IASB. For a reconciliation of operating profit presented in accordance with IFRS as issued by the IASB and operating profit presented in accordance with K-IFRS, see “— Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS” and note 5(2) of the notes to our consolidated financial statements.

 

   

Cellular services: The segment operating profit of our cellular services segment increased by 10.0% to Won 1,007.8 billion in 2020 from Won 915.8 billion in 2019, due to the greater increase in segment operating revenue as compared to the increase in segment operating expense, for the various reasons described above. The segment operating margin (which, with respect to each reportable segment, is segment operating profit (loss) divided by revenue from such segment, expressed as a percentage) of our cellular services segment increased to 8.2% in 2020 from 7.5% in 2019.

 

   

Fixed-line telecommunication services: The segment operating profit of our fixed-line telecommunication services segment increased by 79.9% to Won 244.1 billion in 2020 from Won 135.7 billion in 2019, mainly due to the aggregate impact of the Tbroad Merger as described above. As a result, the segment operating margin of our fixed-line telecommunication services segment increased to 7.2% in 2020 from 4.6% in 2019.

 

   

Security services: The segment operating profit of our security services segment decreased by 15.9% to Won 112.4 billion in 2020 from Won 133.6 billion in 2019, due to the greater increase in segment operating expense as compared to the increase in segment operating revenue, for the various reasons described above. As a result, the segment operating margin of our security services segment decreased to 9.0% in 2020 from 12.0% in 2019.

 

   

Commerce services: The segment operating profit of our commerce services segment increased by 445.0% to Won 10.9 billion in 2020 from Won 2.0 billion in 2019, due to the greater increase in segment operating revenue as compared to the increase in segment operating expense, for the various reasons described above. As a result, the segment operating margin of our commerce services segment increased to 1.4% in 2020 from 0.3% in 2019.

 

   

Others: The segment operating loss of our others segment decreased by 67.2% to Won 25.9 billion in 2020 from Won 78.9 billion in 2019, due to the greater increase in segment operating revenue as compared to the increase in segment operating expense as described above. As a result, the segment operating margin of our others segment improved to (2.9)% in 2020 from (9.8)% in 2019.

Finance Income and Finance Costs.    Our finance income increased by 69.7% to Won 241.2 billion in 2020 from Won 142.2 billion in 2019, primarily due to an increase in gain on valuation of derivatives to Won 101.3 billion in 2020 from Won 2.5 billion in 2019, which primarily related to an increase in valuation of warrants of Nano-X Imaging Ltd. held by SK Telecom TMT Investment Corp., as well as an increase in gain relating to financial assets at fair value through profit or loss to Won 35.8 billion in 2020 from Won 4.5 billion in 2019, primarily relating to shares of Oceanbridge Co., Ltd. held by Quantum Innovation Fund I. The effect of such increases was partially offset by a decrease in gain on settlement of derivatives to Won 7.8 billion in 2020 from Won 29.3 billion in 2019, which amount in 2019 was primarily related to the share exchange transaction with Kakao in October 2019.

Our finance costs increased by 13.5% to Won 497.2 billion in 2020 from Won 438.0 billion in 2019, primarily due to the incurrence of other financial fees of Won 44.7 billion in 2020 relating to the disposal of certain securities held for trading of Knet Culture and Contents Venture Fund, a consolidated subsidiary, and a loss on valuation of derivatives of Won 13.6 billion in 2020 primarily related to certain share subscription rights granted to financial investors of Eleven Street under an equity interest agreement, compared to no such costs incurred in 2019. The effect of such increases was partially offset by a decrease in interest expense to Won 399.2 billion in 2020 from Won 406.1 billion in 2019 as a result of a decrease in interest rates, as well as a loss on sale of other accounts receivable related to handset installment payments of Won 5.8 billion in 2019 compared to nil in 2020.

Gains (Losses) Related to Investments in Associates and Joint Ventures. Gains related to investments in associates and joint ventures increased by 128.8% to Won 1,028.4 billion in 2020 from Won 449.5 billion in 2019, primarily due to an increase in share of profits of SK Hynix to Won 995.1 billion in 2020 from Won 416.2 billion in 2019. Such increase was due to an increase in SK Hynix’s profit for the year to Won 4,758.9 billion in 2020 from Won 2,009.1 billion in 2019.

Income Tax. Income tax expense increased by 25.4% to Won 376.5 billion in 2020 from Won 300.3 billion in 2019 primarily due to a 61.7% increase in profit before income tax to Won 1,877.0 billion in 2020 from Won 1,161.0 billion in 2019. Our effective tax rate in 2020 decreased to 20.1% from 25.9% in 2019, which was primarily attributable to an increase in the proportion of our gains related to investments in associates and joint ventures in our profit before income tax. When such gains are distributed to us in the form of dividends, the tax rate for such dividends is lower than our statutory tax rate. Our effective tax rates in 2020 and 2019 were lower than the maximum statutory tax rate of 27.5% for both years, primarily due to changes in unrecognized deferred taxes in 2020 and non-taxable income in 2019.

Profit for the Year. Principally as a result of the factors discussed above, our profit for the year increased by 74.3% to Won 1,500.5 billion in 2020 from Won 860.7 billion in 2019. Profit for the year as a percentage of operating revenue and other income was 8.0% in 2020 compared to 4.8% in 2019.

2019 Compared to 2018

Operating Revenue and Other Income. Our consolidated operating revenue and other income increased by 5.3% to Won 17,843.5 billion in 2019 from Won 16,945.9 billion in 2018, due to increases in both operating revenue and other income, as discussed below.

Our consolidated operating revenue increased by 5.1% to Won 17,740.7 billion in 2019 from Won 16,874.0 billion in 2018, primarily due to an increase in security services revenue, and to a much smaller extent, increases in others revenue and fixed-line telecommunications services revenue, which were partially offset by decreases in cellular services revenue and commerce services revenue.

Our consolidated other income increased by 43.0% to Won 102.8 billion in 2019 from Won 71.9 billion in 2018, primarily due to the gain on the transfer of our e-sports business to SK Telecom CS T1 Co., Ltd., a joint venture with Comcast Spectacor that was newly established in February 2019, as well as on the transfer of our former mobile OTT service business, “oksusu,” to Content Wavve in September 2019.

The following sets forth additional information about our operating revenues with respect to each of our reportable segments.

 

   

Cellular services: The revenue of our cellular services segment, which is composed of revenues from wireless service, cellular interconnection, wireless device sales and miscellaneous cellular services, decreased by 1.6% to Won 12,177.5 billion in 2019 from Won 12,378.9 billion in 2018. The decrease in our cellular services revenue was due to decreases in wireless service revenue and cellular interconnection revenue, partially offset by increases in wireless device sales revenue and miscellaneous cellular services revenue

 

   

Wireless service revenue decreased by 2.4% to Won 9,532.4 billion in 2019 from Won 9,770.4 billion in 2018, primarily attributable to the continued increase in the percentage of wireless service subscribers who elected to receive discounted rates in lieu of receiving handset subsidies pursuant to the MDDIA. The impact of such decrease was partially offset by an increase in the number of subscribers that subscribe to our higher-priced unlimited data usage plans and 5G plans.

 

   

Cellular interconnection revenue decreased by 7.1% to Won 494.3 billion in 2019 from Won 532.2 billion in 2018. The decrease was primarily attributable to continued decreases in interconnection rates and land-to-mobile call volume.

 

   

Wireless device sales revenue increased by 4.3% to Won 1,032.1 billion in 2019 from Won 989.1 billion in 2018, primarily due to the launch of our 5G services in April 2019 and the ensuing sales of higher-priced 5G-compatible smartphones.

Miscellaneous cellular services revenue increased by 2.9% to Won 1,118.8 billion in 2019 from Won 1,087.2 billion in 2018, primarily because of an increase in rental income from SK Telecom’s real properties, which is recognized as part of our cellular services segment revenue.

 

   

Fixed-line telecommunications services: The revenue of our fixed-line telecommunication services segment, which is composed of revenues from broadband Internet service and advanced media platform service (including IPTV), fixed-line telephone service, international calling service, fixed-line interconnection and miscellaneous fixed-line telecommunication services, increased by 4.2% to Won 2,940.1 billion in 2019 from Won 2,822.3 billion in 2018, primarily due to increases in our miscellaneous fixed-line telecommunications services revenue and broadband Internet service and advanced media platform service revenue, partially offset by a decrease in fixed-line telephone service revenue.

 

   

Miscellaneous fixed-line telecommunication services revenue increased by 53.4% to Won 677.8 billion in 2019 from Won 441.9 billion in 2018, primarily due to an increase in revenue from our business communications services.

 

   

Revenue from our broadband Internet service and advanced media platform service (including our IPTV service and former mobile OTT service, which was transferred to Content Wavve in September 2019) increased by 2.7% to Won 1,807.5 billion in 2019 from Won 1,760.4 billion in 2018, primarily due to an increase in the number of IPTV subscribers to 5.2 million subscribers as of December 31, 2019 from 4.7 million subscribers as of December 31, 2018 and an increase in the number of premium subscriptions with higher monthly rates and purchases of premium video-on-demand content.

 

   

Fixed-line telephone service revenue decreased by 39.5% to Won 224.5 billion in 2019 from Won 371.3 billion in 2018, primarily due to decreases in the number of fixed-line telephone subscribers (including subscribers to VoIP services of SK Broadband and SK Telink) to 3.9 million as of December 31, 2019 from 4.1 million as of December 31, 2018 and residential calling volume as a result of shifting consumer preferences toward wireless communication.

 

   

Security services: The revenue of our security services segment, which is composed of revenues from our former subsidiaries Former ADT CAPS and SK Infosec (prior to its merger with Former ADT CAPS), increased by 290.3% to Won 1,109.5 billion in 2019 from Won 284.3 billion in 2018. A substantial majority of such increase was due to the inclusion of revenue of Former ADT CAPS for a full year in 2019 compared to a partial year in 2018 following the addition of Former ADT CAPS as a new consolidated subsidiary in October 2018 and, to a much smaller extent, the inclusion of revenue of SK Infosec as a new consolidated subsidiary starting at the end of December 2018.

 

   

Commerce services: The revenue of our commerce services segment, which is composed of revenues from 11st, our open marketplace platform, and SK stoa, our T-commerce network, decreased by 2.4% to Won 710.7 billion in 2019 from Won 728.4 billion in 2018, primarily due to our continued strategic focus to optimize and improve the profitability of our 11st business.

 

   

Others: The revenue of our others segment increased by 21.6% to Won 803.0 billion in 2019 from Won 660.1 billion in 2018, primarily due to the inclusion of revenues of newly consolidated subsidiaries, such as FSK L&S and Incross.

Operating Expense.     Our consolidated operating expense increased by 4.5% to Won 16,836.2 billion in 2019 from Won 16,112.1 billion in 2018, primarily due to a 23.4% increase in depreciation and amortization expenses to Won 3,856.7 billion in 2019 from Won 3,126.1 billion in 2018 and a 23.3% increase in labor costs to Won 2,822.7 billion from Won 2,288.7 billion in 2018, partially offset by a 70.8% decrease in rent expenses to Won 154.8 billion in 2019 from Won 529.5 billion in 2018, a 3.7% decrease in other operating expenses to Won 1,716.4 billion in 2019 from Won 1,782.4 billion in 2018 and a 6.9% decrease in network interconnection expenses from Won 752.3 billion in 2019 from Won 808.4 billion in 2018.

The increase in depreciation and amortization expenses was primarily due to the recognition of depreciation expenses relating to our right-of-use assets following our adoption of IFRS 16, as well as the commencement of

 

67


Table of Contents

amortization of our frequency usage rights for our 5G services. See “— Recently Adopted International Financial Reporting Standards - IFRS 16.”

The increase in labor costs was primarily due to the additional personnel on payroll in connection with our acquisitions of Former ADT CAPS in October 2018 and former SK Infosec in December 2018, as well as the expansion of new businesses such as AI solutions and other platform services.

The decrease in rent expenses was primarily due to the adoption of IFRS 16, pursuant to which we recognized payments on certain of our leased real properties in 2019 as depreciation expenses on right-of-use assets instead of as rent expenses. See “— Recently Adopted International Financial Reporting Standards — IFRS 16.”

The decrease in other operating expenses was primarily due to a decrease in impairment loss on property and equipment and intangible assets to Won 65.9 billion in 2019 from Won 255.8 billion in 2018, which amount in 2018 mainly reflected impairment losses we recognized on the goodwill and intangible assets of our former subsidiary Shopkick.

The decrease in network interconnection expenses was mainly attributable to decreases in wireless-to-fixed-line and fixed-line-to-wireless interconnection rates, as well as decreases in the number of fixed-line telephone subscribers and calling volume.

The following sets forth additional information about our segment operating expense with respect to each of our reportable segments, which do not include certain expenses that are classified as other non-operating expenses under K-IFRS. For more information on the difference between our consolidated operating expense pursuant to K-IFRS and pursuant to IFRS as issued by the IASB, see “ — Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS” and note 5(2) of the notes to our consolidated financial statements.

 

   

Cellular services: The segment operating expense for our cellular services segment increased by 1.6% to Won 11,261.7 billion in 2019 from Won 11,079.0 billion in 2018, mainly attributable to an increase in marketing costs to promote our 5G services and the commencement of amortization of our frequency usage rights for our 5G services.

 

   

Fixed-line telecommunication services: The segment operating expense for our fixed-line telecommunication services segment increased by 8.8% to Won 2,804.4 billion in 2019 from Won 2,576.8 billion in 2018, primarily due to increases in labor costs, marketing costs to gain more subscribers to our ultra-high definition IPTV and high speed broadband Internet services and depreciation and amortization expenses.

 

   

Security services: The segment operating expense for our security services segment increased by 230.1% to Won 975.9 billion in 2019 from Won 295.6 billion in 2018, primarily due to the inclusion of operating expenses of Former ADT CAPS for a full year in 2019 compared to a partial year in 2018 following the addition of Former ADT CAPS as a new consolidated subsidiary in October 2018 and, to a much smaller extent, the inclusion of operating expenses of SK Infosec as a new consolidated subsidiary starting at the end of December 2018.

 

   

Commerce services: The segment operating expense for our commerce services segment decreased by 12.9% to Won 708.7 billion in 2019 from Won 813.4 billion in 2018, primarily due to our continued strategic focus to optimize and improve the profitability of our 11st business.

 

   

Others: The segment operating expense for our others segment decreased by 2.8% to Won 881.9 billion in 2019 from Won 907.4 billion in 2018, primarily as a result of cost-cutting efforts by SK Planet and other subsidiaries in this segment.

Operating Profit.    Our consolidated operating profit increased by 20.8% to Won 1,007.3 billion in 2019 from Won 833.8 billion in 2018, as the increase in operating revenue and other income outpaced the increase in operating expense in 2019.

The following sets forth additional information about our segment operating profit with respect to each of our reportable segments. Our segment operating profit with respect to each of our reportable segments is based on K-IFRS and the sum of segment operating profit for all five reportable segments differs from our consolidated

operating profit presented in accordance with IFRS as issued by the IASB. For a reconciliation of operating profit presented in accordance with IFRS as issued by the IASB and operating profit presented in accordance with K-IFRS, see “— Explanatory Note Regarding Presentation of Certain Financial Information under K-IFRS” and note 5(2) of the notes to our consolidated financial statements.

 

   

Cellular services: The segment operating profit of our cellular services segment decreased by 29.5% to Won 915.8 billion in 2019 from Won 1,299.9 billion in 2018, due to the decrease in segment operating revenue and the increase in segment operating expense, for the various reasons described above. As a result, the segment operating margin (which, with respect to each reportable segment, is segment operating profit (loss) divided by revenue from such segment, expressed as a percentage) of our cellular services segment decreased to 7.5% in 2019 from 10.5% in 2018.

 

   

Fixed-line telecommunication services: The segment operating profit of our fixed-line telecommunication services segment decreased by 44.7% to Won 135.7 billion in 2019 from Won 245.5 billion in 2018, due to the greater increase in segment operating expense as compared to the increase in segment operating revenue, for the reasons described above. As a result, the segment operating margin of our fixed-line telecommunication services segment decreased to 4.6% in 2019 from 8.7% in 2018.

 

   

Security services: Our security services segment had a segment operating profit of Won 133.6 billion in 2019 compared to a segment operating loss of Won 11.3 billion in 2018, due to the aggregate impact of our acquisitions of Former ADT CAPS and SK Infosec as described above. As a result, the segment operating margin of our security services segment improved to 12.0% in 2019 from (4.0)% in 2018.

 

   

Commerce services: Our commerce services segment had a segment operating profit of Won 2.0 billion in 2019 compared to a segment operating loss of Won 85.0 billion in 2018, due to the greater decrease in segment operating expense as compared to the decrease in segment operating revenue, for the reasons described above. As a result, the segment operating margin of our commerce services segment improved to 0.3% in 2019 from (11.7)% in 2018.

 

   

Others: The segment operating loss of our others segment decreased by 68.1% to Won 78.9 billion in 2019 from Won 247.3 billion in 2018, due to the increase in segment operating revenue and the decrease in segment operating expense as described above. As a result, the segment operating margin of our others segment improved to (9.8)% in 2019 from (37.5)% in 2018.

Finance Income and Finance Costs.    Our finance income decreased by 44.5% to Won 142.2 billion in 2019 from Won 256.4 billion in 2018, primarily due to a decrease in gain relating to financial assets at fair value through profit or loss to Won 4.5 billion in 2019 from Won 83.6 billion in 2018, primarily relating to our disposal of 200,000 redeemable convertible preference shares of KRAFTON Co., Ltd. (formerly known as Bluehole Inc.) (“Krafton”) in 2018, as well as a decrease in dividends to Won 10.0 billion in 2019 from Won 35.1 billion in 2018, which was primarily related to a decrease in dividend payments following SK Planet’s disposal of investments in certain real estate funds as well as our disposal of all of our shares of KB Financial Group Inc. in 2018. The effect of such decrease was partially offset by an increase in gain on settlement of derivatives to Won 29.3 billion in 2019 from Won 20.4 billion in 2018, primarily as a result of exchange rate fluctuations.

Our finance costs increased by 13.7% to Won 438.0 billion in 2019 from Won 385.2 billion in 2018, primarily due to an increase in interest expense to Won 406.1 billion in 2019 from Won 307.3 billion in 2018 as a result of an increase in the aggregate amount of our outstanding debentures, which was partially offset by a decrease in loss on foreign currency transactions to Won 12.7 billion in 2019 from Won 38.9 billion in 2018.

Gains (Losses) Related to Investments in Associates and Joint Ventures.    Gains related to investments in associates and joint ventures decreased by 86.3% to Won 449.5 billion in 2019 from Won 3,270.9 billion in 2018, primarily due to a decrease in share of profits of SK Hynix to Won 416.2 billion in 2019 from Won 3,238.1 billion in 2018. Such decrease was primarily due to a decrease in SK Hynix’s profit for the year to Won 2,009.1 billion in 2019 from Won 15,540.0 billion in 2018.

Income Tax.    Income tax expense decreased by 64.4% to Won 300.3 billion in 2019 from Won 844.0 billion in 2018 primarily due to a 70.8% decrease in profit before income tax to Won 1,161.0 billion in 2019 from Won 3,976.0 billion in 2018. Our effective tax rate in 2019 increased to 25.9% from 21.2% in 2018. Our

 

69


Table of Contents

effective tax rates in 2019 and 2018 were lower than the maximum statutory tax rate of 27.5% for both years, primarily due to non-taxable income in 2019 and changes in unrecognized deferred taxes in 2018.

Profit for the Year.    Principally as a result of the factors discussed above, our profit for the year decreased by 72.5% to Won 860.7 billion in 2019 from Won 3,132.0 billion in 2018. Profit for the year as a percentage of operating revenue and other income was 4.8% in 2019 compared to 18.5% in 2018.

Inflation

We do not consider inflation in Korea to have had a material impact on our results of operations in recent years. According to the Korean Statistical Information Service, annual inflation in Korea was 0.5% in 2020, 0.4% in 2019 and 1.5% in 2018.

 

Item 5.B.

Liquidity and Capital Resources

Liquidity

We had a working capital surplus (current assets in excess of current liabilities) of Won 597.1 billion as of December 31, 2020 and Won 236.8 billion as of December 31, 2019. The increase in our working capital as of December 31, 2020 compared to December 31, 2019 was primarily attributable to an increase in short-term financial instruments, which was mainly due to the replacement of certain time deposits with short-term financial instruments upon their maturity. We plan to fund our current liabilities with the cash flow generated by our operations, proceeds from the disposal of investment securities or property and equipment that are no longer deemed profitable and proceeds from additional borrowings, as necessary.

We had cash and cash equivalents, short-term financial instruments and short-term investment securities of Won 2,947.0 billion as of December 31, 2020 and Won 2,268.1 billion as of December 31, 2019. We had outstanding short-term borrowings and current portion of long-term debt of Won 1,049.2 billion as of December 31, 2020 and 1,037.9 billion as of December 31, 2019. As of December 31, 2020, we had credit lines with several local banks that provided for borrowing of up to Won 480.0 billion, all of which was available for borrowing.

Cash flows from operating activities and debt financing have been our principal sources of liquidity. We had cash and cash equivalents of Won 1,369.6 billion as of December 31, 2020 and Won 1,270.8 billion as of December 31, 2019. We believe that we have a variety of alternatives available to us to satisfy our financial requirements to the extent that they are not met by funds generated by operations, including the issuance of debt securities and bank borrowings.

Cash Flows from Operating Activities.     Net cash provided by operating activities was Won 5,821.9 billion in 2020, Won 4,035.0 billion in 2019 and Won 4,332.6 billion in 2018. Profit for the year was Won 1,500.5 billion in 2020, Won 860.7 billion in 2019 and Won 3,132.0 billion in 2018. Net cash provided by operating activities in 2020 increased by 44.3% from 2019 primarily due to the increase in profit for the year as well as a decrease in accounts payable — other at the year-end 2020 compared to the year-end 2019. Net cash provided by operating activities in 2019 decreased by 6.9% from 2018 primarily due to an increase in prepaid expenses at the year-end 2019 compared to the year-end 2018.

Cash Flows from Investing Activities.     Net cash used in investing activities was Won 4,250.4 billion in 2020, Won 3,581.6 billion in 2019 and Won 4,047.7 billion in 2018. Cash inflows from investing activities were Won 428.9 billion in 2020, Won 755.2 billion in 2019 and Won 686.1 billion in 2018. Cash inflows in 2020 were primarily attributable to the net cash inflows from business combinations, which mainly related to the Tbroad Merger, as well as proceeds from disposals of property and equipment, primarily related to the disposal of certain training facilities to SK Hynix. Cash inflows in 2019 were primarily attributable to a decrease in short-term financial instruments, net of Won 254.0 billion, which was mainly in connection with funding our investments in property and equipment, and proceeds from disposals of long-term investment securities of Won 234.7 billion, which was primarily in connection with the disposal of 6,109,000 common shares of Hana Financial Group Inc. for Won 221.1 billion in cash. Cash inflows in 2018 were primarily attributable to proceeds from disposals of long-term investment securities of Won 371.8 billion, primarily in connection with the disposal of all of our shares of KB Financial Group Inc. for Won 179.6 billion in cash and the disposal of redeemable convertible preferred shares of Krafton for Won 130.0 billion in cash and the collection of short-term loans of Won 117.6 billion.

Cash outflows for investing activities were Won 4,679.3 billion in 2020, Won 4,336.8 billion in 2019 and Won 4,733.8 billion in 2018. Cash outflows in 2020, 2019 and 2018 were primarily attributable to expenditures related to the acquisition of property and equipment of Won 3,557.8 billion, Won 3,375.9 billion and Won 2,792.4 billion, respectively, primarily in connection with the acquisition of 5G and LTE equipment, the expansion of our 5G network and the maintenance of our LTE network.

Cash Flows from Financing Activities.     Net cash used in financing activities was Won 1,457.6 billion in 2020, Won 686.7 billion in 2019 and Won 238.3 billion in 2018. Cash inflows from financing activities were Won 3,499.6 billion in 2020, Won 2,047.3 billion in 2019 and Won 4,651.7 billion in 2018. Such inflows were primarily driven by proceeds from long-term borrowings, which provided cash of Won 1,947.8 billion in 2020, nil in 2019 and Won 1,920.1 billion in 2018, and the issuance of debentures, which provided cash of Won 1,421.0 billion in 2020, Won 1,633.4 billion in 2019 and Won 1,809.6 billion in 2018. In 2019, we also received proceeds of Won 300.0 billion from the disposal of our treasury shares to Kakao.

Cash outflows for financing activities were Won 4,957.2 billion in 2020, Won 2,733.9 billion in 2019 and Won 4,890.0 billion in 2018. Cash outflows for financing activities included repayment of long-term borrowings, repayment of debentures, payment of dividends, repayments of other long-term payables and acquisition of treasury shares, among other items. Repayment of long-term borrowings were Won 1,950.9 billion in 2020, Won 89.9 billion in 2019 and Won 1,780.7 billion in 2018. Repayment of debentures were Won 975.5 billion in 2020, Won 940.0 billion in 2019 and Won 1,488.0 billion in 2018. Payment of dividends were Won 742.1 billion in 2020, Won 718.7 billion in 2019 and Won 706.1 billion in 2018. Repayments of other long-term payables were Won 428.1 billion in 2020, Won 428.2 billion in 2019 and Won 305.6 billion in 2018. Acquisition of treasury shares was Won 426.7 billion in 2020.

As of December 31, 2020, we had total long term debt (excluding current portion) outstanding of Won 9,669.5 billion, which included debentures in the amount of Won 7,690.2 billion and bank and institutional borrowings in the amount of Won 1,979.3 billion. As of December 31, 2019, we had total long-term debt (excluding current portion) outstanding of Won 9,226.0 billion, which included debentures in the amount of Won 7,253.9 billion and bank and institutional borrowings in the amount of Won 1,972.1 billion. For a description of our long-term debt, see note 18 of the notes to our consolidated financial statements.

As of December 31, 2020, we had (i) Won 6,974.8 billion aggregate principal amount of Korean Won-denominated debentures outstanding, of which SK Telecom issued Won 5,590.0 billion, SK Broadband issued Won 1,360.0 billion and SK Infosec issued Won 24.8 billion, and (ii) Won 1,632.0 billion aggregate principal

amount of debentures outstanding denominated in U.S. dollars. The fixed interest rates of our debentures range from 1.40% to 6.63% depending on the offering size, maturity, interest rate environment at the time of the offering and currency, among other factors. We have a diversified maturity profile with respect to our debentures. See “— Contractual Obligations and Commitments” for more details.

As of December 31, 2020, substantially all of our foreign currency-denominated long-term borrowings and debentures, which in the aggregate amounted to 15.5% of our total outstanding long-term debt, including the current portion and present value discount as of such date, was denominated in Dollars. However, substantially all of our revenue and operating expenses are denominated in Won. We generally pay for imported capital equipment in Dollars. Appreciation of the Won against the Dollar will result in net foreign currency transaction and translation gains, while depreciation of the Won against the Dollar will result in net foreign currency transaction and translation losses. Changes in foreign currency exchange rates will also affect our liquidity because of the effect of such changes on the amount of funds required for us to make interest and principal payments on our foreign currency-denominated debt. For a description of swap or derivative transactions we have entered into, among other transactions, to mitigate the effects of such losses, see “Item 11. Quantitative and Qualitative Disclosures about Market Risk.”

Capital Requirements

Historically, capital expenditures, repayment of outstanding debt, frequency usage payments and research and development expenditures have represented our most significant use of funds. In recent years, we have also increasingly dedicated capital resources to develop and invest in new growth engines, including our next-generation growth businesses in media, security, commerce, IoT solutions and other innovative products and services offered through our platform services, including AI solutions, and to create synergies among our businesses, including through the adaptation of AI technology.

To fund our scheduled debt repayment and planned capital expenditures over the next several years, we intend to rely primarily on cash flows from operating activities, as well as bank and institutional borrowings, and offerings of debt or equity in the domestic or international markets. We believe that these sources will be sufficient to fund our planned capital expenditures for 2021. Our ability to rely on these alternatives could be affected by the liquidity of the Korean financial markets or by Government policies regarding Won and foreign currency borrowings and the issuance of equity and debt. Our failure to make needed expenditures would adversely affect our ability to sustain subscriber growth and provide quality services and, consequently, our results of operations.

respectively, on capital expenditures related to building and enhancing our wireless networks. Our other non-network related capital expenditures in 2020, 2019 and 2018 primarily related to developing new products, upgrades to our information technology systems and equipment and investments in data infrastructure.

In particular, we have been making capital expenditures to build and expand our 5G network. We commenced commercial 5G services in April 2019. We have also been making capital expenditures to improve our LTE network. For a more detailed description of our 5G and LTE networks, see “Item 4.B. Business Overview — Cellular Services — Digital Wireless Network.” We plan to continue to make capital investments in 2021 to build and expand our 5G network and develop related technologies, as well as to further improve and maintain our LTE network.

The following table sets forth our payment obligations relating to our acquisitions of frequency usage rights.

  15 MHz   Sept. 2013     115.3       2013       43.2       2014-2021  

2.1 GHz

  LTE (30 MHz)   Dec. 2016     141.2       2016       85.3       2017-2021  
  WCDMA (10 MHz)

2.6 GHz

  LTE (40 MHz + 20 MHz)   Aug. 2016     332.5       2016       99.8       2017-2026  

3.5 GHz

  5G (100 MHz)   Dec. 2018     304.6       2018       91.4       2019-2028  

28 GHz

  5G (800 MHz)   Dec. 2018     51.8       2018       31.1       2019-2023  

In case of the 800 MHz spectrum, for which our frequency usage rights were acquired in June 2011 and will expire in June 2021, we make annual payments amounting to 1.6% of the revenues generated from such spectrum in the previous year. In 2020, we made such annual payment in the amount of Won 27.8 billion. For more information, see note 17 of the notes to our consolidated financial statements.

We expect to spend a similar amount for capital expenditures in 2021 compared to 2020 for a range of projects, including investments to expand and improve our newly implemented 5G network, investments to maintain our LTE network and LTE-A services, investments to improve and expand our Wi-Fi network, investments to develop our IoT solutions and platform services business portfolio, including AI solutions, investments in data infrastructure, investments in research and development of 5G technology, investments in businesses that can potentially leverage our 5G network, and funding for mid- to long-term research and development projects, as well as other initiatives, primarily related to the development of new growth businesses, as well as initiatives related to our ongoing businesses in the ordinary course. In November 2020, the MSIT announced plans to reallocate a total of 310 MHz of frequency bandwidths whose usage terms are due to expire in 2021 to KT, LG U+ and us, 95 MHz of which will be allocated to us. The final consideration to be paid by us for such reallocated bandwidths will depend on the number of 5G cell sites constructed by us until 2022, and the aggregate consideration to be paid by KT, LG U+ and us is expected to range between approximately Won 3.2 trillion and Won 3.8 trillion. We would be required to spend additional amounts on capital expenditures in connection with building out our networks on such reallocated bandwidths. However, our overall expenditure levels and our allocation among projects remain subject to many uncertainties. We may increase, reduce or suspend our planned capital expenditures for 2021 or change the timing and area of our capital expenditure spending from the estimates described above in response to market conditions or for other reasons. We may also make additional capital expenditure investments as opportunities arise. Accordingly, we periodically review the amount of our capital expenditures and may make adjustments based on the current progress of capital expenditure projects and market conditions. No assurance can be given that we will be able to meet any such increased expenditure requirements or obtain adequate financing for such requirements, on terms acceptable to us, or at all.

     1,737.7  

2024 and thereafter

     6,552.8  

Investments in New Growth Businesses.     We may also require capital for investments to support our development of new growth businesses.

We made a capital contribution of Won 65.0 billion in 2018 to Dreamus, a manufacturer of digital audio players and other portable media devices of which we had first acquired a 39.3% equity interest in August 2014. Dreamus also operates our music streaming service platform, FLO. As of December 31, 2020, we had a 51.4% equity interest in Dreamus.

In October 2018, we acquired Former ADT CAPS by acquiring a 55.0% interest in LSH, which owned 100% of Former ADT CAPS, for Won 696.7 billion. In December 2018, we merged NSOK with and into Former ADT CAPS. In December 2018, we acquired SK Infosec, Korea’s leading information security company, in a share exchange transaction pursuant to which we issued 1,260,668 treasury shares with an aggregate book value of Won 281.2 billion in exchange for all of the outstanding common shares of SK Infosec from SK Inc. In December 2020, we merged LSH with and into SK Infosec and held a 62.6% equity interest in SK Infosec as of December 31, 2020. We have subsequently merged Former ADT CAPS with and into SK Infosec in March 2021, and the surviving entity, SK Infosec, changed its name to ADT CAPS and has become the principal consolidated subsidiary that operates our security business.

We also increased our interest in id Quantique through the acquisition of additional shares with Won 55.2 billion in cash and Won 5.7 billion in contribution-in-kind in 2018 and capital contributions in cash amounting to Won 12.2 billion in 2019 and Won 6.4 billion in 2020, respectively. As of December 31, 2020, we held a 68.1% equity interest in id Quantique.

In June 2019, we acquired a 34.6% interest in Incross, a digital advertising company, for an aggregate purchase price of Won 53.7 billion, in light of potential synergies with our media and commerce businesses.

From time to time, we may make other investments in telecommunications or other businesses, in Korea or abroad, where we perceive attractive opportunities for investment. From time to time, we may also dispose of existing investments when we believe that doing so would be in our best interest.

Severance Payments.     The defined benefit obligation, which is the total accrued and unpaid retirement and severance benefits for our employees, as of December 31, 2020 was Won 154.9 billion. This amount was reflected in our consolidated financial statements as a liability, which is net of deposits with insurance companies totaling Won 1,127.2 billion to fund a portion of the employees’ severance indemnities.

Also see “Item 6.D. Employees — Employee Benefits” and note 21 of the notes to our consolidated financial statements.

Dividends.     Total cash outflows for payments of dividends amounted to Won 742.1 billion in 2020, Won 718.7 billion in 2019 and Won 706.1 billion in 2018.

In April 2021, we distributed annual dividends at Won 9,000 per share (exclusive of an interim dividend of Won 1,000 per share) to our shareholders for an aggregate payout amount of Won 641.9 billion.

Item 5.C.

Research and Development, Patents and Licenses, etc.

We maintain a high level of spending on our research and development activity. We also donate funds to several Korean research institutes and educational organizations that focus on research and development activity. We believe that we must maintain a substantial in-house technology capability to achieve our strategic goals.

Table of Contents

The main focus of our research and development activity is the development of new wireless technologies and services and value-added technologies and services for our 5G network and LTE network, such as wireless data communications, as well as the development of new technologies that reflect the growing convergence between telecommunications and other industries, such as AI, big data analytics, media, security and mobility. SK Telecom’s research and development activity is centered at our T3K Center, located at our SK T-Tower corporate headquarters in Seoul and our Bundang office in Bundang-gu, Seongnam-si, Gyeonggi-do, Korea, which we established in May 2020 by reorganizing our former AIX Center. To more efficiently manage our research and development resources, our T3K Center is organized as follows:

 

Organization

  

Recent Areas of Focus

ESG Tech Product Hub    Planning and development of products based on technologies in environmental, social and corporate governance (“ESG”) areas; establishment of product-focused research and development system
5GX Intelligence CO    Development and standardization of new 5G technologies; development of MEC products and location-based technologies
AI Transformation CO    Transformation of mobile network operation business based on AI technology; planning and development of products based on AI and big data
T3K Innovation CO    Development of vertical full-stack products and vision AI technologies; discovery of new growth opportunities based on technology and enhancement of technological and corporate value
Loonshot Task Force    Discovery of future growth engines based on technology (including development of Korean-language model and development and commercialization of AI semiconductors)

Each business unit also has its own research team that can concentrate on specific short-term research needs, and some of our consolidated subsidiaries also have their own research and development organizations to focus on activities related to their respective business areas. Such research teams permit our research center to concentrate on long-term, technology-intensive research projects. We aim to establish strategic alliances with selected domestic and foreign companies with a view to exchanging or jointly developing technologies, products and services.

Termination of Directors’ Services

Directors are given a retirement and severance payment upon termination of employment in accordance with our internal regulations on severance payments. Upon retirement, directors who have made significant contributions to our company during their term may be appointed to serve either as an advisor to us or as an officer of an affiliate company.

Audit Committee

Under relevant Korean laws and our articles of incorporation, we are required to have an audit committee under the board of directors. The committee is composed of at least three members, two-thirds of whom must be independent non-executive directors in accordance with applicable rules. The members of the audit committee are appointed annually by a resolution of the general meeting of shareholders. They are required to:

 

   

examine the agenda for the general meeting of shareholders;

 

   

examine financial statements and other reports to be submitted by the board of directors to the general meeting of shareholders;

 

   

review the administration by the board of directors of our affairs; and

 

   

examine the operations and asset status of us and our subsidiaries.

In addition, the audit committee must appoint independent auditors to examine our financial statements. An audit and review of our financial statements by independent auditors is required for the purposes of a securities report. Listed companies must provide such report on an annual, semi-annual and quarterly basis to the FSC and the KRX KOSPI Market.

Our audit committee is composed of four independent non-executive directors: Seok-Dong Kim, Yong-Hak Kim, Jung Ho Ahn and Youngmin Yoon, each of whom is financially literate and independent under the rules of the NYSE as applicable. Seok-Dong Kim is the chairman of the committee. The board of directors has determined that Seok-Dong Kim is an “audit committee financial expert” as defined under the applicable rules of the SEC. See “Item 16A. Audit Committee Financial Expert.”

Independent Director Nomination Committee

This committee is devoted to recommending independent non-executive directors for the board of directors. The objective of the committee is to help promote fairness and transparency in the nomination of candidates for these positions. The board of directors decides from time to time who will comprise the members of this committee. The committee is comprised of one executive director, Jung Ho Park, and two independent directors, Seok-Dong Kim and Jung Ho Ahn. Seok-Dong Kim is the chairman of the committee.

Capex Review Committee

This committee is responsible for reviewing our business plan (including the budget). It also examines major capital expenditure revisions, and routinely monitors capital expenditure decisions that have already been executed. The committee is comprised of one executive director, Young Sang Ryu, and five independent directors, Yong-Hak Kim, Seok-Dong Kim, Jung Ho Ahn and Youngmin Yoon and Junmo Kim. Jung Ho Ahn is the chairman of the committee.

Compensation Review Committee

This committee oversees our overall compensation scheme for top-level executives and directors. It is responsible for reviewing both the criteria for and level of compensation. It is comprised of three independent directors, Yong-Hak Kim, Seok-Dong Kim and Junmo Kim. Yong-Hak Kim is the chairman of the committee.

Corporate Citizenship Committee

This committee was established to help us achieve world-class sustainable growth and to help us fulfill our corporate social responsibilities. It is comprised of three independent directors, Jung Ho Ahn, Youngmin Yoon and Junmo Kim. Youngmin Yoon is the chairwoman of the committee.

Employees

The following table sets forth the numbers of our regular employees, temporary employees and total employees as of the dates indicated:

 

     Regular
Employees
     Temporary
Employees

December 31, 2020

     34,847        6,250        41,097  

Labor Relations

As of December 31, 2020, SK Telecom had a company union consisting of 2,591 regular employees out of 5,232 total regular employees. We have never experienced a work stoppage of a serious nature. Every two years, the union and management negotiate and enter into a new collective bargaining agreement that has a two-year duration, which is focused on employee benefits and welfare. Employee wages are separately negotiated on an annual basis. Our wage negotiations for 2018 were completed in September 2018 and resulted in an average monthly wage increase of 2.5% for SK Telecom employees. Our wage negotiations for 2019 were completed in September 2019 and resulted in an average monthly wage increase of 2.0% for SK Telecom employees. Our wage negotiations for 2020 were completed in September 2020 and resulted in an average monthly wage increase of 2.0% for SK Telecom employees. Our wage negotiations for 2021 were completed in March 2021 and resulted in an average monthly wage increase of 3.0% for SK Telecom employees. We consider our relations with our employees to be good.

Employee Benefits

Since April 1999, we have been required to contribute an amount equal to 4.5% of employee wages toward a national pension plan. Employees are eligible to participate in an employee stock ownership association. We are not required to, and we do not, make any contributions to the employee stock ownership association, although we subsidize the employee stock ownership association through the Employee Welfare Fund by providing low interest rate loans to employees who desire to purchase our stock through the plan in the event of a capitalization by the association.

We are required to pay a severance amount to eligible employees who voluntarily or involuntarily cease employment with us, including through retirement. This severance amount is based upon the employee’s length of service with us and the employee’s salary level at the time of severance. As of December 31, 2020, the defined benefit obligation, which is the accrued and unpaid retirement and severance benefits, of Won 1,278.6 billion for all of our employees are reflected in our consolidated financial statements as a liability, of which a total of Won 1,127.2 billion was funded. Under Korean laws and regulations, we are prevented from involuntarily terminating a full-time employee except under certain limited circumstances. In September 2000, we entered into an employment stabilization agreement with the union. Among other things, in the event that we reorganize a department into a separate entity or we outsource an employee to a separate entity where the wage is lower, this agreement provides for a guarantee of the same wage level for the year that such an event occurs.

Under the Basic Labor Welfare Act, we may also contribute up to 5.0% of our annual earnings before tax for employee welfare. Contribution amounts are determined annually following negotiation with the union. The contribution amount for 2020 was set at 5.00% of SK Telecom’s profit before income tax on a separate basis, or Won 50.0 billion. The contribution amount for 2019 was set at 3.63% of SK Telecom’s profit before income tax on a separate basis, or Won 43.0 billion. The contribution amount for 2018 was set at 3.52% of SK Telecom’s profit before income tax on a separate basis, or Won 43.0 billion.

In addition, we provide our employees with miscellaneous other fringe benefits including medical cost subsidies, family camp programs and sabbatical programs for long-term employees.
