2019 MANAGEMENT REPORT

1- MESSAGE FROM THE MANAGEMENT

The year 2019 started with a positive economic outlook, with the prospect of recovery in growth, employment rates and consumption. Over the months, some events have dampened optimism, such as political crises and delays in the approval of the Pension Reform, which have hurt business and consumer confidence. In the international scenario, the trade war between the United States and China also contributed to making the panorama even more complex.

Despite all the challenges, CSN presented impressive results in the period, recording one of best performances on the Brazilian stock exchange (B3 S.A.). In 2019, the Company also invested heavily in safety and modernization, increasing operational and environmental efficiency.

In the Steel segment, investments of approximately R$250 million in the renovation of Blast Furnace 3, at the Presidente Vargas steelworks, increased its steel production capacity by 500,000 tons per year. In addition to increasing efficiency, the repair also reduced slab costs. Other important revitalization investments were made in steelmaking, sintering and thermoelectric power plants 1 and 2, among other areas.

In the Mining segment, we reached an all-time high of more than 38.5 million tons in billed sales, beating the previous record of 36.9 million tons set in 2016. The Company also reinforced its commitment to eliminate dams from its production process, in a movement that began in 2018 and has enabled it to have 90% of dry filtered waste. The new technology, which reduces environmental impacts, guarantees more safety to the process and reuses a large amount of water present in the tailings.

In 2020, CSN remains strongly committed to increasing productivity, efficiency and safety in all areas, investing in new technologies and processes to remain at the forefront of business, thus enabling it to increasingly contribute to the country's growth.

2- THE COMPANY

With interests in steel, mining, cement, logistics and energy, CSN operates throughout the entire steel production chain, from the mining of iron ore to the production and sale of a wide range of high value-added steel products. Thanks to its integrated production system and exemplary management, CSN’s production costs are among the lowest in the segments in which it operates.

CSN has an installed capacity of 6.7 million tons of steel, of which 5.2 million tons of flat steel and 1.5 million tons of long steel (0.4 million at UPV and 1.1 million at SWT) with total sales volume of 4.5 million tons in 2019. Of this amount, 70% was sold in the domestic market and 30% was exported or sold overseas by the Company’s subsidiaries.

In the mining segment, sales increased by 11% in 2019 compared to the previous year. The Company produced a total of 38.5 million tons in 2019.

CSN is one of the largest industrial electricity consumers in Brazil, holding electricity generation assets through interests in consortiums of hydroelectric power plants, in addition to generating energy integrated into its production process. Self-production of electricity allows CSN to obtain highly competitive energy costs.

3- OUTLOOK, STRATEGY AND INVESTMENTS

CSN has been investing in its five operational segments to enhance its units’ competitive advantages and reviewing the Company’s business portfolio and projects to maximize returns to shareholders.

3.1- STEEL

3.2- MINING

In 2019, CSN sold approximately 38.5 million tons of iron ore, of which 3.6 million tons went to the Presidente Vargas steelworks.

MRS' main business segment is heavy haul (iron ore, coal and coke), which transported around 87.5 million tons in 2019, equivalent to 59.6% of the total volume transported by the Company.

In the container segment, MRS maintained its position among the largest rail transporters in the country, transporting 2.40 million tons in containers in 2019, compared to 1.98 million tons in 2018 and 1.84 million tons in 2017.

MRS’ rail services play a vital role in supplying raw materials and transporting final products. All iron ore, coke and coal consumed by the Presidente Vargas steelworks is transported by MRS, as well as a part of the steel produced by CSN.

6- INNOVATION

The Company has been conducting research, development and innovation activities for over 60 years and was the first national steel company to produce coated and pre-painted steel.

Innovation is part of our essence as a pioneer in process, product and commercial solutions, always committed to quality and the pursuit of new initiatives that deliver higher added value to our customers and stakeholders. CSN seeks to innovate in all its business areas and has structures totally dedicated to innovation, such as CSN Inova and the Research and Development Center.

Created in 2018, CSN Inova is the innovation arm of CSN, which aims to strategically and actively position the Company in the innovation ecosystem. Although there are innovative initiatives throughout the company, CSN Inova is responsible for systematizing and leading the innovation process in an organized and comprehensive way, in order to enable the execution of innovation projects by groups of people with different skills and from different backgrounds.

The essence of CSN - Doing Well, Doing More and Doing Always - guides the innovation pillars of CSN Inova: (i) Process Optimization and Operational Efficiency, (ii) New Sources of Revenue and (iii) Culture and Sustainability. In addition to systematizing and leading the open innovation process (hiring startups and connecting with universities, innovation hubs and other ecosystem agents), CSN Inova - always together with business areas - conducts projects that introduce new methodologies to solve the Company’s challenges, helping the digital transformation process, maximizing the value of CSN's assets and generating opportunities for developing new business for the Company, among others.

In its first cycle of operations, CSN Inova, together with multidisciplinary teams composed of employees, conducted projects related to process digitization and optimization. These projects involved identifying the Company's challenges and implementing solutions presented by startups in the following areas: legal, HR and operations at the Presidente Vargas steelworks. Based on positive initial results, CSN Inova was expanded, with an increase in its scope of action and extension to other areas of the Company, in order to scale the methodology and the positive impacts.

The Research and Development Center also contains physical and computer simulation laboratories, with state-of-the-art equipment, such as the GLEEBLE 3500, which, among other modules, has Large Sample Annealing (the first in Latin America), allowing simulations of thermomechanical processes designed to optimize industrial processes. In addition, CSN's computer simulation laboratory has several software, such as forming and stamping simulation, which allows product performance to be evaluated in advance for various customer applications.

Some projects of the Research and Development Center stood out in 2019.

For the automotive and auto parts market, high-strength products (420 and 500MPa) are being developed to meet the structural application needs of vehicles of the main automakers in Brazil. In addition, CSN has been working in the development of advanced steels (AHSS – Advanced High Strength Steels), in the Dual Phase, Complex Phase (CP) and Press Hardening Steel (PHS) or Hot Forming categories, with a strong trend of increased application in automotive bodies, due to the possibility of forming complex geometries with high mechanical strength requirements for the final product. The polyphase AHSS (Advanced High-Strength Steels) line meets the global demand for materials produced in accordance with current methods, with products featuring high mechanical strength and good forming ability, fully complying with the manufacturing requirements from automakers, as well as requirements related to vehicle safety and lower mass and fuel consumption, thus minimizing gas pollution and environmental impacts.

In the hot-rolled flat steel segment, the focus was on meeting market needs, maintaining the traditional quality of CSN's products, together with the continuous pursuit of reducing the cost of steel and ensuring sustainability. For example, the Company develops a family of high mechanical strength steel for application in structures for photovoltaic panels and high strength steel used to reduce the weight of truck wheels. In the cold-rolled flat steel segment, it is worth highlighting the increase in the supply of extra-fine steel with shiny surface characteristics. We have been working to reduce the thickness of our steel destined to the white line market, as increasingly required by customers. It is also worth mentioning the projects for the development of high-strength steels for the civil construction segment.

Finally, in the pre-painted steel segment, there has been an increase in the diversification of applications, following market trends regarding aesthetics and durability. With regard to the aesthetic effect, new products with pearlescent paints and textured paints have been approved to meet this new market trend. The use of pre-painted steel has allowed CSN to optimize the steel use chain, eliminating manufacturing steps for its customers, thus reducing environmental impacts.

The growing interest of customers in these products has encouraged development of the civil construction, white line and automotive segments.

Supported a skilled technical team and the use of Application Engineering technologies to support customers, CSN seeks excellence in tests and simulations of new materials, allowing it to respond more assertively to demands of the different sectors in which it operates: automotive, white goods, civil construction, metal packaging and industry and distribution. In all of them, we promote the use of innovative steels and innovation in manufacturing processes, allowing customers to cut costs and become more competitive.

7- PEOPLE

CSN’s People Management model is based on the conviction that human capital is a strong competitive advantage and the best way to ensure that the Company stands out in the market where it operates. We transform knowledge into a successful trajectory, based on passion, dedication and competence that generate opportunities, achievements and recognitions.

CSN’s integrated and efficient people management is based on five pillars: Attract; Align and Engage; Evaluate; Develop; Recognize and Reward, investing in projects aimed at professional development and improvement, thereby contributing to the growth of the organization and its people.

In a challenging year, we reinforced our essence of Doing Well, Doing More and Doing Always, embodied in all our People Management processes, programs and projects.

The Company maintains several strategies to guarantee recognition and encourage the professional development of its employees. One of the initiatives is called the Performance Evaluation Program, which is applied to all employees of the CSN Group. The results obtained guide the Individual Development Plan, allow the identification of potential successors of leaders and support the recognition and reward process.

Based on these results, we annually carry out the Career and Succession Program, which aims to identify, with the help of our managers and executives, employees with the potential to succeed leaders of the CSN group. Mapped professionals have their development accelerated through practical and real learning experiences, such as knowledge building workshops (Self-knowledge, Leading People, Communication and Influence, and Planning and Execution), Talk Show with Senior Leaders, Learning Groups and presentation of CSN's real business cases by our executives

This way we guarantee the continuity of our company by ensuring the continuity of our Leadership and Business model, in addition to paying close attention to the career paths of our talents.

In 2019, we invested 33,981,220 hours in training, with the purpose of generating and sharing knowledge, fostering the development of the necessary competencies to achieve corporate goals and ensuring the continuity of the business. The 70/20/10 learning model was the guideline for all the Company’s development actions, ensuring efficiency and effectiveness.

One of our main development action fronts is focused on trainees. The program is implemented in all Business Units and focuses on preparing young people. In 2019, we delivered the following modules: Self-knowledge; Career; Relationship and Communication; and Market: Efficiency, Effectiveness and Creativity.

Our model aims to accelerate learning by training the talents who have the potential to occupy effective positions in the medium and long term, aligning the trainee’s career and development interests with our organizational needs, in addition to contributing to the country's development through education and professional development.

Still in terms of evolution of our business and our managers, we continued the School of Leaders, which was implemented in 2011, with the following modules:

· Challenges of First-time management – Further Development and Delegation and Feedback for supervisors and coordinators;

· Design Thinking in People Management and Developing High-Performance Teams for the Future for managers;

· Skills for the Future and Exponential Business for senior management.

Also in 2019, we offered a special module on Exponential Thinking to our officers.

We believe the continuous training and development of our leaders creates an important opportunity to positively impact all our employees, building a cooperative environment focused on the development of teams and the achievement of excellent results.

The most important milestone for 2019 was the progress of the Internal Trainee Program, whose objective is to develop and empower trainees of the CSN group to generate a positive impact on the organization and increase talent retention. The selection was done based on a group of trainees formed in December 2018.

The eight young people selected underwent a training period that included technical visits to the Group's production units, job rotation through the corporate areas and internal and external development modules. The group is currently allocated to strategic areas, developing projects and acquiring knowledge.

We have established partnerships with several educational institutions for university extension and language courses, with special prices for our employees, thus further encouraging their development.

Once again, we reaffirm that we act as owners, choosing the best strategies to overcome the obstacles faced in 2019. We show that we are working together for the sustainability of the business.

CSN ended 2019 with 24,869 direct employees and 13,435 indirect employees, indicating a turnover rate of 13.42%, one of the lowest in the industrial sector.

ü Investments in the Fazenda Santa Cecília do Ingá Natural Municipal Park, with the revamp of the nursery, production of seedlings and renovation of the Park’s Visitor Center;

ü An urban afforestation program that will include the planting and maintenance of more than 4,000 seedlings of native Atlantic Forest trees in the city.

Since 2010, CSN has been undertaking an inventory of its greenhouse gas emissions, in line with GHG Protocol guidelines, in order to provide input for managing carbon, mitigating risks and adapting to climate change. For the fourth consecutive year, the Company received the Gold Seal of the Brazilian GHG Protocol Program for having disclosed the emissions of all its units and submitted them to external verification. As requested by investors, the Company annually reports the guidelines it follows regarding climate change, supply chain and water resources to the Carbon Disclosure Project (CDP).

The Company’s environmental guidelines also include the monitoring of dams, used to contain tailings from the processing cycle of CSN Mineração’s activities. Pursuant to the dam classification by DNPM Ordinance 70,389/2017, all the dams are audited by independent companies specialized in the subject, aimed at certifying dam stability, or lack thereof, and identifying preventive actions to ensure stability. The Dam Safety Plan and Emergency Action Plan for Mining Dams (PAEBM) of CSN Mineração have been finalized with all necessary consolidated volumes, in compliance with the DNPM ordinance.

The Company is also at the forefront of tailings treatment, having invested around R$400 million in its dams and operations, focusing on the change from wet stacking to dry stacking, which will eliminate the need for tailings dams in the near future.

CSN always acts in a way that minimizes the impacts of its operations, in addition to investing in environmental preservation and education initiatives, confirming its commitment to the quality of life of future generations. CSN has an important social front, the Environmental Education Program (PEA), an initiative managed by the CSN Foundation, with emphasis on the Arcos (MG) and Congonhas (MG) units, designed to reaffirm its commitment to the transformation of values and attitudes through new habits and knowledge. The environmental education project uses art as a tool to engage public school students, teachers and Company employees in discussions, with emphasis on issues related to historical and natural heritage in the areas where the Company operates.

Finally, CSN has been constantly mapping its stakeholders and, since 2012, the Company has used mapping criteria to assess environmental, social and economic impacts, in accordance with the Global Reporting Initiative (GRI) guidelines and adopts Integrated Reporting (IR) methodology to develop indicators for all its operations. The data and indicators obtained in this process allow CSN to monitor its performance and assess its exposure to social and environmental risks and future opportunities. The outcomes of this work can be found in the Reports published on the website http://ri.csn.com.br/.

1. DESCRIPTION OF BUSINESS

Companhia Siderúrgica Nacional “CSN”, also referred to as “the Company” or “Parent Company”, is a publicly-held company incorporated on April 9, 1941, under the laws of the Federative Republic of Brazil (Companhia Siderúrgica Nacional, its subsidiaries, joint ventures, joint operations and associates are collectively referred to herein as the "Group”). The Company’s registered office is located in São Paulo, SP, Brazil.

CSN is listed on the São Paulo Stock Exchange (B3 S.A.- Brasil, Bolsa, Balcão) and on the New York Stock Exchange (NYSE). Accordingly, the Company reports its information to the Brazilian Securities and Exchange Commission (CVM) and the U.S. Securities and Exchange Commission (SEC).

The Group's main operating activities are divided into five (5) segments as follows:

· Steel:

The Company’s main industrial facility is the Presidente Vargas steelworks (“UPV”), located in the city of Volta Redonda, State of Rio de Janeiro. This segment consolidates all operations related to the production, distribution and sale of flat steel, long steel, metallic containers and galvanized steel. In addition to the facilities in Brazil, CSN has commercial operations in the United States and operations in Portugal and Germany to achieve markets and providing excellent services for final consumers. Its steel is used in home appliances, civil construction and automobile industries.

· Mining:

The production of iron ore is developed in the cities of Congonhas, Ouro Preto and Belo Vale, State of Minas Gerais, by subsidiary CSN Mineração.

Iron ore is sold basically in the international market, especially in Europe and Asia. The prices charged in these markets are historically cyclical and subject to significant fluctuations over short periods of time, driven by several factors related to global demand, strategies adopted by the major steel producers, and the foreign exchange rate. All these factors are beyond the Company’s control. The ore transportation is carried out through Terminal de Carvão e Minérios do Porto de Itaguaí – (“TECAR”), a solid bulk terminal, one of the four terminals that comprise the Itaguaí Port, in State of Rio de Janeiro. Imports of coal and coke are also carried out through this terminal by provision of services by CSN Mineração to CSN. The Company´s mining activities also comprises tin exploitation, which is based in the State of Rondônia, to supply the needs of the UPV. The excess of these raw material is sold to subsidiaries and third parties.

The Company's mining activities utilize tailings dams for which all appropriate measures are taken to mitigate the risks inherent to the handling and disposal of the tailings and to comply with current environmental legislation. It is important to reiterate that operating without dependence on these dams is a priority in our mining activities, for which approximately R$ 250 million were invested in two tailings filtration plants, which are already in an operational ramp up phase, adapting its operation, identifying and implementing various optimization of process. As a result, CSN Mineração will now process dry tailings in full, discarding the use of dams in their iron ore activities. As a consequence of these measures, decommissioning of dams is the natural way of processing dry tailings.

All of our mining dams are positively certified and comply with the environmental legislation in force.

· Cement:

CSN entered the cement market boosted by the synergy between this activity and its existing businesses. Next to the Presidente Vargas Steelworks (UPV) in Volta Redonda (RJ), the Company installed a new business unit that produces CP-III type cement using slag produced by the UPV’s blast furnaces. It also exploits limestone and dolomite at the Arcos unit in the State of Minas Gerais, to meet the needs of the UPV and of the cement plant. Additionally, the operation clinker production line is located in Arcos/MG. As a result, the Company is self-sufficient in the production of cement, with an installed capacity of 4.7 million tons per year.

· Logistics

Railroads:

CSN has interests in three railroad companies: MRS Logística S.A., which manages the Southeast Railway System of the former Rede Ferroviária Federal S.A. (“RFFSA”), Transnordestina Logística S.A. (“TLSA”) and FTL - Ferrovia Transnordestina Logística S.A. (“FTL”), which the latter two hold the concession to operate the former Northeast Railway System of RFFSA, in the States of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco, Alagoas and Sergipe, with TLSA being responsible for the rail links of Eliseu Martins - Trindade, Trindade- Salgueiro, Salgueiro-Porto de Suape, Salgueiro- Missão Velha and Missão Velha- Pecém (Railway System II), under construction and FTL being responsible for the rail links of São Luiz- Altos, Altos – Fortaleza, Fortaleza - Souza, Souza – Recife/Jorge Lins, Recife/Jorge Lins-Salgueiro, Jorge Lins-Propriá, Paula Cavalcante – Cabedelo, Itaibaiana - Macau (Railway System I).

Ports:

The Company operates in the State of Rio de Janeiro, through its subsidiary Sepetiba Tecon S.A., the Container Terminal ("TECON”) and through its subsidiary CSN Mineração S.A., TECAR, both at the Itaguaí Port. Locate in the Bay of Sepetiba, they have privileged highway, railroad and maritime access.

TECON handles and stores containers, vehicles, steel products, general cargo, among other products, and TECAR performs the operational activities of loading and unloading of solid bulk ships, storage and distribution (road and rail) of coal, coke, petroleum coke, clinker, zinc concentrate, sulfur, iron ore and other bulk, intended for the seaborne market, for own consumption or for different customers.

· Energy:

As energy is fundamental to its production process, the Company has electric energy generation assets to guarantee its self-sufficiency.

Note 25 - “Segment Information” details the financial information per CSN´s business segment.

· Going Concern

In 2019, the Company amortized principal and interest in the approximate amount of R$13.8 billion of its loans and financing. In 2020, loans and interest to be incurred next year, are expected to be paid in the approximate amount of R$6.5 billion. The financial leverage may adversely affect the Company’s business, financial conditions and operating results, which the following main impacts are considered by management:

· Allocation of a substantial part of the cash generated from operations for repayment of the borrowings.

· Exposure (i) to fluctuations in interest rates due to the renegotiation of debts and new borrowings taken, and (ii) fluctuations in exchange rates since a significant part of the borrowings is denominated in foreign currency.

· Increase in the economic and financial vulnerability due to adverse conditions of the industry and segment, limiting the funds available in the short term, considering the high financial leverage and the expected cash disbursements;

· Limitation of the Company’s ability to enter into new businesses (acquisitions) until the financial leverage is reduced;

· Limitation of the Company’s ability to obtain new credit lines under more favorable interest conditions due to the risks associated to the current financial leverage.

The Company’s ability to continue operating depends, therefore, on the achievement of operating targets defined by management, in addition to refinancing of contracted debts, and/or actions related to financial deleveraging.

In addition to the continuous focus on improvement in operating income, management has various actions in progress to increase the Company’s liquidity through an extension of borrowing payment terms. This plan was started in 2015, with the renegotiation of R$2.5 billion with Caixa Econômica Federal and R$2.2 billion with Banco do Brasil S.A, postponing the maturities from 2016 and 2017 to 2018 through 2022. In 2016, the Company extended the installments of certain NCE contracts amounting to R$100 million and prepayments of US$66 million with Bradesco, postponing the maturities from

2016 to 2019, which are settled during that year. Always committed to the plan to extend it debt payment term, mainly those of short term, the company’s management concluded, in February 2018, the reprofile of its debts at R$4.98 billion with Banco do Brasil, extending the maturity dates from 2018 to 2022 for maturities up to 2024. Still in February 2018, the company issued debt instruments (“Notes”) in the amount of US$350 million through our wholly-owned subsidiary CSN Resources S.A., with maturity date in 2023 and, in conjunction, made a repurchase offer (“Tender Offer”) of the Notes previously issued by CSN Islands XI Corp and CSN Resources S.A, having been repurchased US$350 million in Notes with maturities scheduled for 2019 and 2020. In April 2019, the Company issued debt securities in the foreign market (“Notes”), in the amount of US$ 1 billion through its subsidiary CSN Resources S.A., being: US$400 million due in 2023 and US$600 million with maturity in 2026. Promoted a repurchase offer (“Tender Offer”) of Notes issued by CSN Islands XI Corp and CSN Resources S.A., and US$1 billion in securities were repurchased, with maturities scheduled for September 2019 and July 2020, respectively. In July 2019, the Company issued debt securities on the foreign market (“Notes”), in the amount of US$ 175 million through its subsidiary CSN Resources S.A., due in 2023 and promoted the final payment of the debt in the foreign market (“Notes”) issued by the company CSN Islands XI Corp in September 2019, in US$142 million.

Additionally, Management studies alternatives to financial deleverage from the disposal of non-strategic assets. However, it is not possible to affirm that the sale of assets will occur within a 12-month period. Thus, the Company did not segregate and did not reclassify any assets in the financial statements as discontinued operations in accordance with CPC 31 (IFRS 5).

Based on management’s cash flow projections that covered the operational period until February 2021, which depend on factors such as the achievement of production targets, sales volumes and prices, as well as on renegotiations of borrowings, management believes that the Company has appropriate resources to continue its operations in a reasonably estimable period of time. Accordingly, the Company’s financial statements for the year ended December 31, 2019 were prepared based on the assumption of going concern.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

2.a) Basis of preparation and declaration of conformity

The consolidated and parent company financial statements have been prepared and are being presented in accordance with accounting practices adopted in Brazil based on the provisions of the Brazilian Corporate Law, pronouncements, guidelines and interpretations issued (CPC), approved by CVM, besides the own standards issued by the Brazilian Securities and Exchange Commission (“CVM”) and International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standard Board (IASB) and highlight all the relevant information at the financial statements, and only this information, which correspond to those used by the Company's management in its activities

The preparation of the financial statements in accordance with IFRS and standards issued by the CPC requires the use of certain critical accounting estimates and also the exercise of judgment by the Company's management in the process of applying the Company's accounting policies.

Information on uncertainties related to assumptions and estimates, which have a significant risk of resulting in a material adjustment to the accounting balances of assets and liabilities in the year, are included in the following notes:

• Note 5 - Recognition of the provision for expected losses (impairment) of accounts receivable from customers;

• Note 14 - Deferred income and social contribution taxes: availability of future taxable income against which deductible temporary differences and tax losses can be used;

• Note 10.a - Goodwill impairment test (impairment);

• Note 12 - Derivative financial instruments and hedge accounting (“Hedge accounting”).

• Note 16 - Provision for tax, social security, labor, civil, environmental and judicial deposits: main assumptions about the probability and magnitude of resource outflows;

• Note 26 - Retirement benefit;

The financial statements are presented in thousands of reais (R$). Depending on the applicable IFRS standard, the measurement criterion used in the preparation of the financial statements considers the historical cost, the net realizable value, fair value or recovery value. When IFRS and CPCs allow a choice between the cost of acquisition or other measurement criteria, the acquisition cost criterion was used

The consolidated and parent company interim financial statements were approved by the Management on March 04, 2020.

· Exclusive funds

	Equity interests (%)
Exclusive funds	12/31/2019	12/31/2018	Core business
Direct interest: full consolidation

VR1 - Private credit balanced mutual fund	100.00	100.00	Investment fund

In preparing the consolidated financial statements, we have adopted the following consolidation procedures:

· Transactions between subsidiaries, associates, joint ventures and joint operations

Unrealized gains on transactions with subsidiaries, joint ventures and associates are eliminated to the extent of CSN’s equity interests in the related entity by the consolidation process. Unrealized losses are eliminated in the same manner as unrealized gains, although only to the extent that there are not indications of impairment. The Company eliminates the effect on profit or loss of transactions carried out with joint ventures and, as a result, reclassifies part of the equity in results of joint ventures to financial expenses, cost of sales and income tax and social contribution.

The base date to the financial statements of the subsidiaries and joint ventures is the same as of the Company, and their accounting policies are also in line with the policies adopted by the CSN.

Subsidiaries

Subsidiaries are all entities, which financial and operating policies can be conducted by the Company and when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to use its power to affect its returns. The existence and effect of potential voting rights that are exercisable or convertible are taken into consideration when assessing whether the Company controls another entity. Subsidiaries are fully consolidated from the date when the control is transferred to the Company and are deconsolidated from the date when such control ceases.

Joint ventures and joint operations

Joint arrangements are all entities over which the Company has joint control with one or more other parties. The investments in joint arrangements are classified as joint operations or joint ventures depending on the contractual rights and obligations of each investor.

Joint operations are accounted for in the financial statements in order to represent the Company's contractual rights and obligations. Therefore, the assets, liabilities, revenues and expenses related to its interests in joint operations are accounted for individually in the financial statements.

Joint ventures are accounted for under the equity method and are not consolidated.

The Company eliminates the effect on profit or loss of transactions carried out with joint ventures and, as a result, eliminates part of the equity in results of joint ventures to financial expenses, cost of sales, net sales and income tax and social contribution.

Associates

Associates are all entities over which the Company has significant influence but not control, generally through a shareholding percentage from 20% up to 50% of the voting rights. Investments in associates are accounted for under the equity method and are initially recognized at cost.

Page 36

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

· Transactions and non-controlling interests

The Company treats transactions with non-controlling interests as transactions with owners of the Company. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of subsidiary net assets is recorded in shareholders' equity. Gains and losses on disposals to non-controlling interests are also recognized directly in shareholders' equity.

When the Company no longer holds control, any retained interest in the entity is remeasured to its fair value, with the change in the carrying amount recognized in profit or loss. The fair value is the initial carrying amount for the purposes of subsequently accounting for the retained interest in an associate, joint venture or financial asset. In addition, any amounts previously recognized in other comprehensive income in respect of that entity are accounted for as if the Company had disposed of the related assets or liabilities. It means that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

2.c) Parent company financial statements

In the parent company financial statements, investments in subsidiaries and associates are accounted for by the equity method. To get the same result and equity attributable to equity holders in parent company and consolidated financial statements, are made in both financial statements, the same practice of adjustments upon adoption of IFRS and CPCs.

2.d) Foreign currencies

i. Functional and presentation currency

Items included in the financial statements are related to each one of the Company's subsidiaries are measured using the currency of the primary economic environment in which the subsidiary operates (“functional currency”). The consolidated financial statements are presented in Brazilian reais (R$), which is the Company’s functional currency and the Group’s presentation currency.

ii. Transactions and balances

Transactions in foreign currencies are translated into the functional currency using the exchange rates in effect at the dates of the transactions or valuations when their values are remeasured. Foreign exchange gains and losses resulting from the settlement of those transactions and from the translation at exchange rates in effect as of December 31, 2019 related to monetary assets and liabilities denominated in foreign currencies are recognized in the income statement as financial result, except when they are recognized in shareholders' equity as a result of foreign operation characterized as foreign investment.

According CPC 02 and ICPC 21 – foreign currency transactions and advance consideration, the transactions in which the Company recognizes a non-monetary asset or non-monetary liability involving prepayments or receipts in foreign currency are recorded at the exchange rate of the date the entity initially recognized (transaction date) the non-monetary asset or non-current liability monetary.

The balances of assets and liabilities are translated by exchange rates prevailing at the end of the reporting period. As of December 31, 2019, US$1 is equal to R$4.0307 (R$3.8748 at December 31, 2018) and €1 is equal to R$4.5305 (R$4.4390 at December 31, 2018), according to the rates obtained from Central Bank of Brazil website.

All other foreign exchange gains and losses, including foreign exchange gains and losses related to borrowings and cash and cash equivalents, are presented in the income statement as financial income or expenses.

iii. Group companies

The results and financial position of all the Group’s entities (none of which has the currency of a hyper-inflationary economy) that have a functional currency different from the presentation currency are translated into the presentation currency as follows:

Page 37

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

· The assets and liabilities of each balance sheet presented are translated by exchange rate at the end of the reporting period;

· The income and expenses of each income statement are translated at average exchange rates (unless this average is not a reasonable approximation of the cumulative effect of the rates at the transaction dates, in which case income and expenses are translated at the rate in effect at the transaction dates);

· All resulting exchange differences are recognized as a separate component in other comprehensive income; and

· Gains and losses accumulated in shareholders' equity are included in the income statement when the foreign operation is partially disposed or sold.

2.e) Cash and cash equivalents

Cash and cash equivalents include cash on hand, in bank accounts and other short-term highly liquid investments redeemable within 90 days from the end of the reporting period, readily convertible into a known amount of cash and subject to an insignificant risk of change in value. Bank certificates of deposit and government securities that do not meet the above criteria are not considered cash equivalents and are classified as financial investments, according to note 4.

2.f) Trade receivables

Trade receivables are initially recognized at fair value, including the related taxes and expenses, being foreign currency-denominated trade receivables are adjusted at the exchange rate in effect at the end of the reporting period.

With the adoption of the new CPC 48/IFRS 9 - Financial instruments, the Company started to apply the new model of expected losses, where it considers all possible loss events over the life of its receivables. These expected credit losses are estimated according to the loss rate by maturity range adopted by the Company since the initial (recognition) date of the asset.

The Company considers customer history, default rate, financial situation and the position of its legal advisors to estimate the expected credit losses.

2.g) Inventories

Inventories are carried at the lower of cost and net realizable value. Cost is determined using the weighted average cost method on the acquisition of raw materials. The costs of finished goods and work in process comprise raw materials, labor and other direct costs (based on the normal production capacity). Net realizable value represents the estimated selling price in the normal course of business, less estimated costs of completion and costs necessary to make the sale. The allowance for estimated losses on slow-moving or obsolete inventories are recognized when considered necessary.

Stockpiled ore inventories are accounted for as processed when removed from the mine. The cost of finished goods comprises all direct costs necessary to transform stockpiled inventories into finished goods.

2.h) Investments

Investments in subsidiaries, joint ventures and associates are accounted for under the equity method of accounting and are initially recognized at cost. In the parent company financial statements, the gains or losses are recognized in profit or loss as operating income (or expenses). In the case of foreign exchange differences arising on translating foreign investments that have a functional currency different from the Company’s, changes in investments due exclusively to foreign exchange differences, as well as adjustments to pension plans that impact the subsidiaries’ shareholders' equity, are recognized in line item “Cumulative translation adjustments”, in the Company’s shareholders' equity, and are only recognized in profit or loss when the investment is disposed or written off due to impairment loss. Other investments are recognized at cost or fair value.

When necessary, the accounting policies of subsidiaries, joint ventures and associates are changed to ensure consistency with the policies adopted by the Company.

2.i) Investment property

The Company's investment properties consist of land and buildings maintained to earn rental income and capital appreciation. The measurement method used is the acquisition or construction cost less accumulated depreciation and impairment, when applicable. Accumulated depreciation is calculated by linear method based on the estimated useful life of the properties subject to depreciation, see note 8.g. Land is not depreciated as they have an indefinite useful life.

2.j) Business combination

The acquisition method is used to account for on each business combination conducted by the Company. The consideration transferred by acquiring an entity is measured by the fair value of the assets transferred, liabilities incurred, and equity instruments issued by the Company. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement, where applicable. Acquisition-related costs are recognized in profit or loss for the year, as incurred. Identifiable assets acquired, and liabilities assumed in a business combination are initially measured at their fair values at the acquisition date.

2.k) Property, plant and equipment

Property, plant and equipment are carried at cost of acquisition, formation or construction, less accumulated depreciation or depletion and any impairment loss. Depreciation is calculated under the straight-line method based on the remaining economic useful economic lives of assets, as mentioned in note 9. The depletion of mines is calculated based on the quantity of ore mined. Land is not depreciated since their useful life is considered indefinite. However, if the tangible assets are mine-specific, that is, used in the mining activity, they are depreciated over the shorter between the normal useful lives of such assets and the useful life of the mine. The Company recognizes in the carrying amount of property, plant and equipment the cost of replacement, and consequently reducing the carrying amount of the part that is replaced if it is probable that future economic benefits embodied therein will revert to the Company, and if the cost of the asset can be reliably measured. All other disbursements are expensed as incurred. Borrowing costs related to funds obtained for construction in progress are capitalized until these projects are completed.

If some components of property, plant and equipment have different useful lives, these components are accounted for in separate line items of property, plant and equipment.

Gains and losses on disposal are determined by comparing the sale value less the residual value and are recognized in ‘Other operating income (expenses)’.

Exploration expenditures are recognized as expenses until the viability of mining activities is established; after this period the subsequent development costs are capitalized. Exploration and valuation expenditures include:

· Research and analysis of historical data related to area exploration;

· Topographic, geological, geochemical and geophysical studies;

· Determine the mineral asset’s volume and quality/grade;

· Examine and test the extraction processes and methods;

· Topographic surveys of transportation and infrastructure needs;

· Market and financial studies;

The development costs from new mineral deposits or from capacity expansion in mine operations are capitalized and amortized using the produced (extracted) units’ method based on the probable and proven ore quantities.

The development stage includes:

· Drillings to define the ore body;

· Access and draining plans;

· Advance removal of overburden (top soil and waste material removed prior to initial mining of the ore body) and waste material (non-economic material that is intermingled with the ore body).

Stripping costs (the costs associated with the removal of overburden and other waste materials) incurred during the development of a mine, before production commences, they are capitalized as part of the depreciable cost of developing the property. Such costs are subsequently amortized over the useful life of the mine based on proven and probable reserves.

Stripping costs in the production phase are included in the cost of the inventory produced, except when a specific extraction campaign is made to access deeper deposits where ore body is located. In these cases, costs are capitalized and taken to noncurrent assets when the mineral ore deposit is extracted and are amortized over the useful life of the ore body.

Version: 1

The Company holds spare parts that will be used to replace parts of property, plant and equipment and that used to increase the asset’s useful life when it exceeds 12 months. These spare parts are classified in property, plant and equipment and not in inventories.

2.l) Leases

When entering into a contract, the Company assesses whether the contract is, or contains, a lease. The lease is characterized by a lease or transmission of the right of use for a fixed period in exchange for monthly payments. O leased asset must be clearly specified.

The Company determines in the initial recognition, the lease term or non-cancellable term, which will be used in the measurement of the right-to-use assets and lease liabilities. The lease term will be reassessed by the Company when a significant event or significant change occurs in the circumstances that are in the control of the lessee and affect the non-cancellable term. The Company adopts exemption from recognition, as provided for in the standard, for the lessee contracts with terms of less than 12 (twelve) months, or whose underlying asset object of the contract is of low value.

On the start date, the Company recognizes the right to use asset and the lease liability at present value. The asset right of use must be measured at cost. The cost includes the lease liability, initial costs, advance payments, estimated costs to dismantle, remove or restore. The lease liability is measured on the start date by the Company at the present value of the lease payments that are made on that date. The payments are discounted at the interest rate implicit in the lease, or if the rate cannot be determined, an incremental rate will be used on the Company's borrowing.

For contracts that the Company determines the business rate, it is understood that this rate is the rate implied in terms and which is applied to discount the flow of future payments. In contracts with no rate definition, the Company applied the incremental borrowing rate, obtaining it through consultations with banks where it has a relationship, adjusted for the expected inflation for the coming years.

For the subsequent measurement, is used the cost method to the right-of-use assets and for depreciation, the requirements of CPC 27 - Property, Plant and Equipment. However, for the purpose of depreciation, the Company determines the use of the linear method based on the remaining useful life of the assets or the term of the contract, whichever is shorter.

The effects of PIS and COFINS recoverable generated after the effective payment of the obligations will be recorded as a reduction of depreciation expenses for the right to use and financial expenses recognized monthly.

CPC 01 - Impairment of Assets will also be applied in order to determine whether the right-of-use asset has impairment indicators and to account for any impairment loss identified.

2.m) Intangible assets

Intangible assets comprise assets acquired from third parties, including through business combinations.

These assets are recognized at cost of acquisition or formation, less amortization calculated on a straight-line basis on the exploration or recovery periods estimated.

Mineral rights acquired are classified as rights and licenses in intangible assets.

Intangible assets with indefinite useful lives and goodwill based on expected future profitability are not amortized.

Version: 1

· Goodwill

Goodwill represents the positive difference between the amount paid and/or payable for the acquisition of a business and the net fair values of the acquired subsidiary’s assets and liabilities. Goodwill on acquisitions from business combination is recognized as intangible assets in the consolidated financial statements. In the parent company statements, goodwill is included in investments. The gain for bargain purchase is recognized as a gain in profit for the period at the acquisition date. Goodwill is annually tested for impairment or at any time when circumstances indicate a possible loss. Impairment losses on goodwill are not reversed. Gains and losses on the disposal of a Cash-Generating Unit (CGU) include the carrying amount of goodwill related to the CGU sold.

Goodwill is allocated to CGUs for impairment testing purposes. The allocation is made to CGUs or group of CGUs that are expected to benefit from the business combination in which the goodwill arose, and if that unit is not greater than the operating segment.

· Software

Software licenses purchased are capitalized based on the costs incurred to purchase the software and make it ready for use. These costs are amortized on a straight-line basis over the estimated useful lives in up to 10 years.

2.n) Impairment of non-financial assets

Assets with infinite useful lives, such as goodwill, are not subject to amortization and are annually tested for impairment. Assets subject to amortization and/or depreciation, such as property, plant and equipment and investment property, are tested for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. An impairment loss is recognized at the amount at which the carrying amount of the asset exceeds its recoverable amount. The recoverable amount is the higher of the fair value of an asset less costs to sell and its value in use. For impairment testing purposes, assets are grouped at their lowest levels for which there are separately identifiable cash flows (Cash Generating Units, or CGUs). Non-financial assets, except for goodwill, which have suffered impairment, are subsequently reviewed for possible reversal of the impairment at the reporting date.

2.o) Employee benefits

· Employee benefits

Defined contribution plans

A defined contribution plan is as a post-employment benefit plan whereby an entity pays fixed contributions to a separate entity (pension fund) and will not have any legal or constructive obligation to pay additional amounts. Obligations for contributions to defined contribution pension plans are recognized as employee benefit expenses in the periods during which services are provided by employees. Contributions paid in advance are recognized for an asset since it is agreed that either cash reimbursement or future reduction on payables will be available. Contributions to a defined contribution plan that is expected to mature twelve (12) months after the end of the period in which the employee provides services are discounted to their present values.

Defined benefit plans

A defined benefit plan is a post-employment benefit plan other than a defined contribution plan. The Company’s net obligation regarding defined pension benefit plans is calculated individually for each plan by estimating the value of the future benefit that the employees accrue as return for services provided in the current period and in prior periods; such benefit is discounted to its present value. The discount rate is the yield presented at the end of the reporting period for top line debt securities whose maturity dates approximate the terms and conditions of the Company’s obligations and which are denominated in the same currency as the one in which it is expected that the benefits will be paid. The calculation is made annually by a qualified actuary using the projected unit credit method. When the calculation results in a benefit for the Company, the asset to be recognized is limited to the total amount of any unrecognized costs of past services and the present value of the economic benefits available in the form of future reimbursements or reduction in future contributions to the plan. The present value of economic benefits is calculated considering the funding requirements applicable to the Company’s plans. An economic benefit is available to the Company if it is realizable during the life of the plan or upon settlement of the plan’s liabilities.

Version: 1

The Company and some of its subsidiaries offered a postretirement healthcare benefit to its employees. The right to these benefits is usually contingent to their remaining in employment until the retirement age and the completion of the minimum length of service. The expected costs of these benefits are accumulated during the employment period and are calculated using the same accounting method used for defined benefit pension plans. These obligations are annually valued by qualified independent actuaries.

When the benefits of a plan are increased, the portion of the increased benefit related to past services of employees is recognized in profit or loss until the benefits become vested. When benefits became vesting rights, expenses are immediately recognized in profit or loss.

The Company recognizes all actuarial gains or losses resulting from defined benefit plans immediately in other comprehensive income. If the plan is extinguished, actuarial gains or losses are recognized in profit or loss.

· Profit sharing and bonus

Employee profit sharing and executives’ variable compensation are linked to the achievement of operating and financial targets. The Company recognizes a liability and an expense substantially allocated to production cost and, where applicable, to general and administrative expenses when such goals are met.

2.p) Provisions

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that the Company will be required to settle the obligation and it has reliable cost estimation.

The amount recognized as a provision is the best value estimation required to settle the present obligation at the end of the reporting period, considering the risks and uncertainties surrounding the obligation. When a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows (when the effect of the time value of money is material). Success fees are accrued to the extent that they make it probable that disbursements will occur. When some or all the economic benefits required to settle a provision are expected to be recovered from a third party, a receivable is recognized as an asset if it is probable that reimbursement will be received and that the amount of the receivable can be measured reliably.

2.q) Share capital

Common shares are classified in shareholders' equity.

Incremental costs directly attributable to the issue of new shares or options are shown in shareholders' equity as a deduction to the amount received, net of taxes.

When any Company of the Group buys Company shares (treasury shares), the amount paid, including any directly additional costs (net of income tax), is deducted from shareholders' equity attributable to owners of the Company until the shares are canceled or sold. When these shares are subsequently sold, any amount received, net of any directly attributable additional transaction costs and the related income tax and social contribution effects, is included in shareholders' equity attributable to owners of the Company.

2.r) Revenue recognition

As of January 1, 2018, CPC 47/IFRS 15 was adopted by the Company, all assets are recorded according to the respective practice.

Operating revenue from the sale of goods in the normal course of business is measured at the fair value of the consideration that the entity expects to receive in exchange for the delivery of the good or service promised to the client.

Page 42

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

Revenue recognition occurs when or as the entity satisfies a performance obligation by transferring the good or service to the customer, understanding that performance obligation is an enforceable promise in a contract with a customer for the transfer of a good / service or a series of goods or services.

The transfer is considered effected when or as the customer obtains control of that asset.

If it is probable that discounts will be granted and the value thereof can be reliably measured, then the discount is recognized as a reduction of the operating revenue as sales are recognized.

Freight export services under the CFR (Cost and Freight) and CIF (Cost, Insurance and Freight) modalities, where the Company is responsible for the freight service, are considered separate services and therefore a separate obligation, with their allocation apart of the price of the transaction and with recognition of the service over time. Such revenue allocated to freight does not significantly affect the results of the Company's fiscal year and, therefore, it is not presented separately in the financial statements. For other services rendered, revenue is recognized based on its realization.

2.s) Financial income and financial expenses

Financial income includes interest income from funds invested, dividend income not accounted for under the equity method, changes in the fair value of financial assets measured at fair value through profit or loss, and gains on derivative instruments that are recognized in profit or loss. Interest income is recognized in profit or loss under the effective interest method. Dividend income is recognized in profit or loss when the Company’s right to receive payment has been established. Distributions received from investees accounted for under the equity method reduce the investment value.

Financial expenses comprise interest expenses on borrowings, dividends on preferred shares, losses on the fair value of financial instruments measured at fair value through profit or loss, impairment losses recognized in financial assets, and losses on derivative instruments that are recognized in profit or loss. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are measured through profit or loss under the effective interest method.

Foreign exchange gains and losses are reported on a net basis.

2.t) Income tax and social contribution

Current income tax and social contribution are calculated based on the tax laws enacted by the end of the reporting period, including in the countries where the Group entities operate and generate taxable profit. Management periodically assesses the positions taken in the tax calculations with respect to situations where applicable tax regulations are open to interpretations. The Group recognizes provisions where appropriate, based on the estimated payments to tax authorities. The income tax and social contribution expense comprises current and deferred taxes. Current and deferred taxes are recognized in profit or loss unless they are related to business combinations or items recognized directly in shareholders' equity.

Current tax is the expected tax payable or receivable on taxable profit or loss for the year at tax rates that have been enacted by the end of the reporting period and any adjustment to taxes payable in relation to prior years.

Deferred tax is recognized on temporary differences between the carrying amounts of assets and liabilities in the financial statements and the corresponding tax bases used in the computation of taxable profit. Deferred tax is not recognized for the following temporary differences: initial recognition of assets and liabilities in a transaction that is not a business combination and does not affect either the accounting or taxable profit or loss, and differences associated with investments in subsidiaries and joint ventures when it is probable that they will not reverse in the foreseeable future.

Moreover, a deferred tax liability is not recognized for taxable temporary differences resulting from the initial recognition of goodwill. The deferred tax is measured at the rates that are expected to be applied on temporary differences when they reverse, based on the laws enacted by the end of the reporting period.

Current income tax and social contribution are carried at their net amounts by the taxpayer, in liabilities when there are amounts payable or in assets when prepaid amounts exceed the total amount due at the end of the reporting period.

Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority on the same entity subject to taxation.

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

A deferred income tax and social contribution asset is recognized for all tax losses, tax credits, and deductible temporary differences to the extent that it is probable that taxable profits will be available against which those tax losses, tax credits, and deductible temporary differences can be utilized. Annually, the Company reviews and verifies the existence of future taxable income and a provision for loss is recognized when the realization of these credits is not likely.

2.u) Earnings/(Loss) per share

Basic earnings/loss per share are calculated by means of the profit/loss for the year attributable to owners of the Group and the weighted average number of common shares outstanding in the related period. Diluted earnings/loss per share are calculated by means of the average number of shares outstanding, adjusted by instruments potentially convertible into shares, with diluting effect, in the reported periods. The Group does not have any instruments potentially convertible into shares and, accordingly, diluted earnings/loss per share are equal to basic earnings/loss per share.

2.v) Environmental and restoration costs

The Company recognizes a provision for the recovery costs and fines when a loss is probable, and the amounts of the related costs can be reliably measured. Generally, the period when the provision for recovery is recognized coincides with the end of a feasibility study or the commitment to adopt a formal action plan.

Expenses related to compliance with environmental regulations are charged to profit or loss or capitalized, as appropriate. Capitalization is considered appropriate when the expenses refer to items that will continue to benefit the Group and that are basically related to the acquisition and installation of equipment to control and/or prevent pollution.

Asset retirement obligation (A.R.O) asset retirement obligations consist of cost estimates by deactivation, demobilization or restoration of areas at the end of exploration and resource extraction activities minerals. The initial measurement is recognized as a liability discounted to present value and, subsequently, by the increase expenditure over time. The asset deactivation cost equivalent to the initial liability is capitalized as part of the book value of the asset being depreciated over the useful life of the asset.

2.w) Research and development

Research expenditures are recognized as expenses when incurred. Expenditures on project developments (related to the design and testing stages of new or improved products) are recognized as intangible assets when it is probable that projects will be successful, based on their commercial and technological feasibility, and only when the cost can be reliably measured. When capitalized, development expenditures are amortized from the start of a product commercial production, on a straight-line basis and over the period of the expected benefit.

2.y) Financial instruments

As of January 1, 2018, CPC 48 / IFRS 9 was adopted by the Company, all assets and liabilities are recorded according to the respective practice.

i) Financial assets

Assets are classified according to the definition of the business plan adopted by the Company and the characteristics of the cash flow of the financial asset.

· Recognition and measurement

The Company classifies, at initial recognition, its financial assets into three categories: i) assets measured at amortized cost ii) fair value through profit or loss and iii) fair value through other comprehensive income.

Page 44

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

i. Amortized cost

Assets measured at amortized cost must be measured if both of the following conditions are met: i) the financial asset is maintained within the business plan whose objective is to maintain financial assets for the purpose of receiving contractual cash flows ii) the contractual terms of the financial asset give rise, on specific dates, to cash flows that exclusively constitute payments of principal and interest on the principal amount outstanding, the Company shall recognize its interest income, exchange gains and losses and impairment directly in the income statement

ii. Fair value through profit or loss

Financial assets should be measured at fair value through profit or loss only if they are not measured as assets measured at amortized cost or fair value through other comprehensive income.

iii. Fair value through other comprehensive income.

Financial assets shall be measured at fair value through comprehensive income only when the following conditions are met: i) the financial asset is maintained within a business plan whose objective is achieved by the receipt of contractual cash flow and by the sale of financial assets, ii) the contractual terms of the financial asset give rise, in specific dates and interest on the value of the outstanding principal.

The assets measured at fair value through other comprehensive income are classified into two categories: i) debt instruments in which the interest income calculated using the effective interest method, the foreign exchange gains and losses and the impairment are recognized in the statement of income. Other net income is recognized directly in the Company's equity, in "other comprehensive income". In derecognition, the accumulated result in other comprehensive income is reclassified to income, and ii) equity instrument in which these assets are measured subsequent to the fair value. The dividends are recognized as a gain in profit or loss, unless the dividend represents a clear recovery of part of the cost of the investment. Other net income is recognized directly in the Company's equity in "other comprehensive income" and is never reclassified to income.

The fair values of publicly quoted investments are based on current purchase prices. If the market for a financial asset (and for instruments not listed on a stock exchange) is not active, the Company establishes the fair value by using valuation techniques. These techniques include the use of recent transactions contracted with third parties, reference to other instruments that are substantially similar, analysis of discounted cash flows, and option pricing models that make maximum use of market inputs and relies as little as possible on entity-specific inputs.

Regular purchases and sales of financial assets are recognized at the trading date on which the Company undertakes to buy or sell the asset.

· Derecognition of financial assets

Financial assets are derecognized when the rights to receive cash flows from the investments have expired or have been transferred, in the latter case, provided that the Company has transferred significantly all risks and rewards of ownership.

If the company holds substantially all the risks and rewards of ownership of the financial asset, it must continue to recognize the financial asset.

ii. Financial liabilities

Financial liabilities are classified under the following categories: financial liability at amortized cost or fair value through profit or loss. Management determines the classification of its financial liabilities at the time of initial recognition.

· Financial liabilities measured at amortized cost

The Company shall classify all its financial liabilities as amortized cost, except financial liabilities classified at fair value through profit or loss, derivative liabilities, collateral agreement.

Page 45

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

Other financial liabilities are measured at amortized cost using the effective interest method. The interest expenses, gains and losses are recognized in the income statement.

The Company holds the following non-derivative financial liabilities: borrowings, financing, dividends, leases, forfeit, debentures and trade payables.

· Financial liabilities at fair value through profit or loss

Financial liabilities classified in category fair value through profit or loss are financial liabilities held for trading or those designated at the time of initial recognition.

Derivatives are also classified as trading securities, and thereby are classified so, unless they have been designated as effective hedging instruments.

Gains and losses on financial liabilities classified at fair value through profit or loss are recognized in profit or loss

· Derecognition of financial liabilities

Financial liabilities are written off only when they are extinguished, that is, when the obligation specified in the agreement is settled, canceled or expires. The Company also derecognizes a financial liability when the terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value.

ii) Offsetting of financial instruments

Financial assets and financial liabilities are offset, and the net amount is reported in the balance sheet when there is a legally enforceable right to set off the recognized amounts as well as the intention to either settle them on a net basis or to realize the asset and settle the liability simultaneously.

iv) Derivative instruments and hedging activities

· Derivatives measured at fair value through profit or loss

Derivatives are initially recognized at fair value on the date when a derivative contract is entered, thereafter they are subsequently measured at their fair value and any changes are recognized as Financial income /(expenses) in the income statement.

· Cash flow Hedge

The Company adopts hedge accounting and designates certain financial liabilities as a hedging instrument of a foreign exchange risk associated to the cash flows from forecast, highly probable exports (cash flow hedges).

At the inception of the transaction, the Company documents the relationships between the hedging instruments and the hedged items, as well as its risk management objectives and strategy for undertaking hedging transactions. The Company also documents its assessment, both at the inception of the hedge and on an ongoing basis, of whether the hedging transactions are highly effective in offsetting changes in the cash flows of the hedged items.

The effective portion of the changes in the fair value of financial liabilities designated and qualifying as cash flow hedge is recognized on equity, in line item "Hedge accounting”. Any gain or loss related to the ineffective portion is recognized immediately in other operational income/expenses, if applicable.

The amounts accumulated in equity are realized in operational result in the periods when the forecast exports affect the result.

When a hedging instrument expires, is settled in advance or the hedging relationship no longer meets the hedge accounting criteria, or even when Management decides to discontinue hedge accounting, all cumulative gains or losses recorded in equity at the time remain recognized in equity and, from that moment, the exchange variations are recorded in the financial income/expenses. When the forecast transaction is completed, the gain or loss is reclassified to operational result. When a forecast transaction is no longer expected to take place, the cumulative gain or loss previously recognized in shareholders’ equity is immediately transferred to the income statement, in line item “Other operating”.

Page 46

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

The movements of the hedge amounts denominated as export cash flow hedges are shown in note 12 – Financial Instruments.

· Net investment hedge

For net investment hedge, the Company designates part of its financial liabilities as hedging instruments of its overseas investments with functional currencies other than the Group’s functional currency, according to CPC38/IAS39. Such relationship occurs since the financial liabilities are related to the investments in the amounts required for the effective relationship.

At the inception of the hedge relationship, the Company documents the relationship between the hedging instrument and the hedged item, along with its risk management objectives and its strategy for undertaking hedge transactions. Furthermore, at the inception of the hedge and on an ongoing basis, the Company documents whether the hedging instrument is highly effective in offsetting changes in fair values of the hedged item.

The effective portion of changes in the fair value of financial liabilities that are designated and qualify as a net investment hedge is recognized in equity in line item “Hedge Accounting”. The gain or loss relating to the ineffective portion is recognized in other operating, when applicable. If at some point of the hedging relationship the balance of the debt is higher than the balance of the investment, the exchange variation on the excess debt will be reclassified to the statement of profit or loss as other operating income / expenses (ineffectiveness of the hedge).

The amounts accumulated in equity will be realized in the statement of profit or loss upon disposal or partial disposal of the foreign operation.

The changes in the amounts of hedge denominated as Net investment hedge are shown in note 12 – Financial Instruments.

2.z) Segment information

An operating segment is a component of the Group committed to the business activities from which it can obtain revenues and incur expenses, including revenues and expenses related to transactions with any other components of the Group. All the operating results of operating segments are reviewed regularly by the Executive Officers of CSN to enable decisions regarding resources to be allocated to the segment and assessment of its performance. The Company maintains distinct financial information for the distinct segments.

2.a.a) Government grants

Government grants are recognized when there is reasonable assurance that:

- the Company will comply to the conditions attaching to them;

- assurance that the grants will be received.

Government grants will be recognized as revenue on a systematic basis over the periods in which the Company recognizes the related costs that the grants are intended to compensate.

The Company has state tax incentives in the South, North and Northeast regions, which are recognized in profit or loss as a reduction of the corresponding costs, expenses and taxes.

2.a.b) Noncurrent assets held for sale and discontinued operations

Noncurrent assets and groups of assets are classified as held for sale if their carrying amount is recovered mainly through a sale transaction and not through continued use.

The criteria for classification of items held for sale are considered to be met only when the sale is highly probable, and the asset or group of assets is available for immediate sale.

Page 47

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

Assets and liabilities classified as held for sale are presented separately as current items in the balance sheet.

Classification as a discontinued operation occurs through disposal, or when the transaction meets the criteria to be classified as held for sale if this occurs earlier. A discontinued operation is a component of a Group business which comprises operations and cash flows that may be clearly distinct from the rest of the Group and represent a separate business line or geographical area of operations.

The result of discontinued operations is presented in a single amount in the income statement, including the total income after income tax of these operations, less any impairment loss.

2.a.c) Statement of value added

Pursuant to Law 11,638/07, the presentation of the statement of value added is required for all publicly-held companies. These statements were prepared in accordance with CPC 09 - Statement of Value Added, approved by CVM Resolution 557/08. The IFRS does not require the presentation of this statement and for IFRS purposes is presented as additional information.

The statement of value added should highlight the wealth generated by the Company and demonstrate its distribution.

2.a.d) New standard and interpretation not yet adopted

The following standard and interpretation has been issued and will be mandatory for subsequent accounting periods, that is, as of January 1, 2020 and 2021 and were not early adopted by the Group for the year ended December 31, 2019:

1. Refers to the excess of judicial deposit originated by the 2009 REFIS (Tax Debt Refinancing Program).

2. Refers mainly to PIS / COFINS, ICMS recoverable and income and social contribution taxes to be offset. On September 20, 2018, the writ of mandamus and special appeal filed in 2006, in which CSN and Federal Union were parties, related to the discussion about the non-inclusion of ICMS in the calculation base of PIS and COFINS, confirmed the CSN's right to offset the amounts over-collected from 2001 to 2014.

3. Refers a payment of freight expenses and maritime insurance over revenues didn’t recognized.

4. Long-term iron ore inventories that will be used after the construction of the processing plant, which will produce pellet feed, expected to start operating from the second half of 2021.

5. This is certain and due amount, arising from the res judicata favorable decision to the Company, which is irreversible and irrevocable, to apply the STJ's consolidated position on the subject, which culminated in the conviction of Eletrobrás to the payment of the correct interest and monetary adjustment of the Compulsory Loan. The res judicata decision, as well as the certainty about the amounts involved in the liquidation of the sentence (judicial procedure to request the satisfaction of the right), allowed the conclusion that the entry of this value is certain. In addition to this amount already recorded, the Company continues to seek alternatives for the recovery of additional credits and the estimate can reach an amount greater than R$ 350 million.

· TRANSNORDESTINA LOGÍSTICA S.A. (“TLSA”)

TLSA is primarily engaged in the public service operation and development of a railroad network in the Northeast of Brazil network, comprising the rail segments of Eliseu Martins to Trindade, Trindade to Salgueiro, Salgueiro to Porto Suape, Salgueiro to Missão Velha and Missão Velha to Pecém (Railway II).

It is in pre-operational phase and will continue as such until the completion of Railway System II. The approved schedule, which estimated the completion of the work by January 2017, is currently under discussion with the responsible agencies, according described in item 27.b. The Management understands that new deadlines for project completion will not have material adverse effects on the expected return on the investment.

During the year 2017, the other shareholders of TLSA subscribed 2,912,997 shares in the amount of R$153,253, diluting CSN's stake in the share capital of TLSA to 46.30%. As a result of the operations described above and the variation in the shareholders 'participation in the share capital of TLSA in 2017, the Company recorded a gain in the amount of R$ 2,814 recorded in shareholders' equity in other comprehensive income. In May 2019, the Northeast Investment Fund - FINOR transferred to CSN, BNDES and BNDESPAR, 1,677,816 (one million six hundred seventy-seven thousand, eight hundred and sixteen) class “B preferred shares, of which 501,789 (five hundred and one thousand, seven hundred and eighty-nine) shares were transferred specifically to CSN. On 12/31/2019, the Company's interest in the capital of TLSA is 47.26% of the total capital and 92.60% of the voting capital.

The Management receives funds from its shareholders and third parties for completion of the works, according described in the item 27.b, which are expected to be available, based on agreements previously entered and recent discussions between the involved parties. After analyzing this matter, Management concluded as adequate the use of the accounting base of the project’s going concern in the preparation of the financial statements for the year ended December 31, 2019.

In this direction, TLSA performed an impairment test of its own long-live assets using the discount cash flow method and considered the main assumptions, as follows:

Measurement of recoverable value:

Cash Flow Projection	Until 2057
Gross Margin	Based on market studies to capture operations costs and loads, based on studies of market trends.
Estimated Costs	Costs based on studies and market trends.
Growth rate in perpetuity	Growth rate was not considered due to the projection model until the end of the concession.
Discount rate	Between 5.09% to 6.98% in real terms.

In addition, CSN, as an investor, performed an impairment test of its stake in TLSA, through TLSA ability to distribute dividends, methodology known as Dividend Discount Model, or DDM, to remunerate the capital invested by shareholders. In order to perform this test, some aspects were taken into account, such as:

· The flow of dividends was obtained from the TLSA nominal cash flow;

· The flow of dividends was calculated considering the annual percentages of participation, considering the dilutions of the CSN’s stakes due to the amortization of debts;

· This flow of dividends was discounts at present value using cost of equity (Ke) embedded in the WACC rate of TLSA; and

· This Ke obtained was the one calculated in the “rolling WACC” of TLSA.

Due to the sharing of investors risks, and by the fact that the asset that is being tested represents the cash-generating unit itself, which is equal to the legal entity, the risk determined by CSN Management is the same applied by TLSA when the evaluation of their own investments, not applying an additional risk fator to the model.

As a result, it was not necessary to recognize an impairment in the surplus-value of the investments in the year ended on December 31, 2019.

10.a) Impairment testing

The goodwill arising from expectations for future profitability of the companies acquired and the intangible assets with indefinite useful lives (trademarks) have been allocated to the operational divisions (cash-generating units) of CSN, which represent the lowest level of assets or group of assets. According to CPC 01(R1)/ IAS36, when a CGU has an intangible asset with indefinite useful life allocated, the Company performs an impairment test. The CGU with intangible assets in this situation are as follows:

(1) The goodwill of the Packaging cash-generating unit is shown net of impairment loss in the amount of R$109,330, recognized in 2011.

(2) The goodwill and trademark that are recorded in line item intangible assets at long steel segment, those transactions are derived from the business combination of Stahlwerk Thuringen GmbH ("SWT") and Gallardo Sections CSN. The assets mentioned are considered to have indefinite useful lives as they are expected to contribute indefinitely to the Company's cash flows.

(3) Refers to the goodwill based on expectations for future profitability, resulting from the acquisition of Namisa by CSN Mineração, concluded in December 2015, tested annually for the purpose of analyzing recoverability.

(4) On November 29, 2019, CSN acquired the entire stake held by CKTR Brasil Serviços Ltda., corresponding to 50% of CBSI's shares, and now holds 100% of CBSI's share capital.

The impairment testing of the goodwill and the trademark include the balance of property, plant and equipment of the cash-generating units and also the intangible assets. The test is based on the comparison between the actual balances and the value in use of those units, determining based on the projections of discounted cash flows and use of such assumptions and judgements as: growth rate, costs and expenses, discount rate, working capital, future Capex investment and macroeconomic assumptions observable in the market.

The main assumptions used in calculations of value in use at December 31, 2019 are as follows:

	Metal packaging	Mining	Other Steel	*Flat steel ()**	Logistic ()**
Measurement of recoverable value	Discounted Cash Flow	Discounted Cash Flow	Discounted Cash Flow	Discounted Cash Flow	Discounted Cash Flow
Cash flow projection	Until 2029 + perpetuity	Until 2054	Until 2029 + perpetuity	Until 2029 + perpetuity	Until 2027
Gross Margin	Gross margin updated based on historical data, impacts of business restructuring and market trends	Reflects projection of costs due to the progress of the mining plan as well as startup and ramp up of projects. Price and exchange rate projected according industry reports.	Gross margin updated based on historical data and market trends	Gross margin updated based on historical data and market trends.	Estimated based on market studies for cargo captures and operational costs according market trends.

Perpetual growth rate	Without growth	Without perpetuity	Without growth	Growth of 1.4% p.a in real terms updated by long term inflation of 1.7% p.a. of the Euro zone	Without perpetuity
Discount rate	For metal packaging, the cash flow considered a discount rate around 8% p.a. in real terms. For mining, flat steel and other steel (CBSI), cash flows considered a discount rate between 10% and 12% p.a. in nominal terms. For the logistic segment, cash flow was discounted using a discount rate between 5.09% and 5.41% p.a. in real terms. The discount rate was based on the weighted average cost of capital ("WACC") that reflects the specific risk of each segment.

(*) Refer to assets of subsidiary Lusosider, located in Portugal. The discount rate was applied on the discounted cash flow prepared in Euros, the functional currency of this subsidiary.

(**) Refer to assets of subsidiary FTL – Ferrovia Transnordestina Logística S.A.

For the subsidiary SWT – long steel, the measurement of recoverable value was based on fair value and classified as Level 3, based on unobservable inputs that reflect the assumptions that market participants would use for pricing, including risk assumptions and discount rate.

Based on the analyses conducted by Management, it was not necessary to record losses by impairment to those assets for the year ended on December 31, 2019.

12. FINANCIAL INSTRUMENTS

I - Identification and measurement of financial instruments

The Company can operate with various financial instruments, mainly cash and cash equivalents, including short-term investments, marketable securities, trade receivables, trade payables, and borrowings and financing. The Company also can operate into derivative transactions, currency swap, interest rate swap and commodity swap operations.

Considering the nature of the instruments, the fair value is basically determined using quotations in the open capital market of Brazil and the Commodities and Futures Exchange. The amounts recorded in current assets and liabilities have immediate liquidity or maturity, mostly in short time maturity. Considering the term and the characteristics of these instruments, the carrying amounts approximate the fair values.

• Share market price risks

The Company is exposed to the risk of changes in the price of the shares due to the investments, valued at fair value through profit or loss that have their prices based on the market price on B3.

III - Financial risk management:

The Company follows risk management strategies, with guidelines in relation to the risks incurred by the company. The nature and general position of financial risks is regularly monitored and managed to assess the results and the financial impact on cash flow. The credit limits and hedge quality of the counterparties are also periodically reviewed.

Market risks are protected when it is considered necessary to support the corporate strategy or when it is necessary to maintain the level of financial flexibility.

The Company may manage some of the risks through the use of derivative instruments, not associated with any speculative trading or short selling.

12.a) Foreign exchange rate and interest rate risks:

· Foreign exchange rate risk:

The exposure arises from the existence of assets and liabilities denominated in Dollar or Euro, since the Company's functional currency is substantially the Real and is denominated natural currency hedge. The net exposure is the result of offsetting the natural currency exposure by hedging instruments adopted by CSN.

· Cash flow hedge accounting

The Company formally designate cash flow hedging relationships to hedge highly probable future cash flows against US dollar fluctuations - relating to sales made in US dollars.

In order to better reflect the accounting impacts of this foreign exchange hedging strategy on the Company’s results, CSN designated part of its US dollar-denominated liabilities as a hedging instrument of its future exports. As a result, foreign exchange differences arising from designated liabilities will be temporarily recognized in shareholders’ equity and recognized in profit or loss when such exports are carried out, allowing the concurrent recognition of the dollar fluctuations on liabilities and on exports. The adoption of this hedge accounting does not entail entering any financial instrument. As of December 31, 2019, US$2,530,713 in exports to be carried out from October 2019 until April 2026 are designated.

In order to support the designations, the Company prepared formal documentation indicating how the hedge designation is aligned with CSN's objective and risk management strategy, identifying the hedging instruments used, the hedge object, the nature of the risk to be hedged and demonstrating the expectation of high effectiveness of the designated relations. Debt instruments have been designated in amounts equivalent to the portion of future exports. The Company carries out continuous assessments of prospective and retrospective effectiveness, comparing the amounts designated with the amounts expected and approved in the Management's budgets, as well as the amounts exported.

Through hedge accounting, the exchange gains and losses on debt instruments will not immediately affect the Company’s profit or loss except to the extent that exports are carried out.

The table below shows a summary of the hedging relationships as of December 31, 2019:

· Hedge of net investment in foreign operation

CSN has a natural currency exposure in Euros substantially arising from a borrowing taken by a foreign subsidiary with functional currency in Reais, for the acquisition of investments abroad where the functional currency is Euro. Such exposure arises from translating the balance sheets of these subsidiaries for consolidation into CSN, where the exchange variation on the borrowings affected the statement of income, in the financial result line item, and the exchange variation on the net assets of the foreign operation directly affected the shareholder’s equity, in other comprehensive income.

The Company adopted IFRS 16 / CPC 06 (R2) as of January 1, 2019, using the modified retrospective approach that does not require the presentation of comparative balances. As a result of adopting IFRS 16/CPC 06 (R2), the Company changed the accounting policy for lease agreements.

The Company has lease agreements for port terminals in Itaguaí, the Cargo Terminal - TECAR, used for the loading and unloading of iron ores and the Container Terminal - TECON, the agreements have a remaining term of 28 and 32 years respectively and contract lease for railway operation using the Northeast network with a remaining term of 8 years.

CSN also has lease agreements for operating equipment, used in mining and steel operations, with terms of 2 to 5 years.

The present value of future obligations was measured using the implicit rate observed in the contracts, for contracts that did not have a rate, the Company applied the incremental borrowing rate - IBR, both in nominal terms

The IBR was acquired through consultation with the Company's relationship banks according to the average term of the contracts, following the guidelines of Official Letter / CVM / SNC / SEP No. 02/2019.

The average rates used to measure the lease and rights to use:

			12/31/2019
Contract term (in years)	Incremental - IBR (a.a)		Implicit (a.a)
Contract term (in years)	BRL	EURO	BRL

· Payments of leases not recognized as liabilities:

The Company chose not to recognize lease liabilities in contracts with a maturity of less than twelve months and for assets with low value. The realized payments to these contracts are recognized as expenses, when incurred.

The Company has lease agreements for the use of ports (TECAR) and railways (FTL) which, even if they establish minimum performance, cannot determine their cash flow since these payments are fully variable and will only be known when they occur. In such cases, payments will be recognized as expenses when incurred

Expenses related to payments not included in the measurement of a lease liability during the actual exercise are:

	Consolidated	Parent Company
	12/31/2019	12/31/2019
Contract less than 12 months	10,819	-
Lower Assets value	3,853	7,464
Variable lease payments	177,460	21,211
	192,132	28,675

In accordance with the guidelines of CPC 06 (R2) / IFRS 16, the Company uses the discounted cash flow technique to measure and remeasure liabilities and right to use, without considering the projected inflation in the flows to be discounted.

(1) The Company taxes exchange differences on a cash basis to calculate income tax and social contribution on net income.

In its corporate structure the Company has foreign subsidiaries whose profits are subject to income tax in the countries where they were established at rates lower than those prevailing in Brazil. In the period from 2014 and 2019, these foreign subsidiaries generated profits amounting to R$1,406,562. If the tax authorities understand that these profits are subject to additional taxation in Brazil in respect of income tax and social contribution, these, if due, would total approximately R$453,927. The Company, based on its legal counsel’s opinion, assessed as possible the likelihood of loss in the event of challenge by the tax authorities and, therefore, no provision was recognized in the financial statements.

In addition, management evaluated the precepts of IFRIC 23 - “Uncertainties Over Income Tax Treatments” and considers that there are no reasons for the tax authorities to differ from the tax positions adopted by the Company. Accordingly, no additional provisions for income tax and social contribution were recognized as a result of the assessment of the application of IFRIC 23 in the financial statements at December 31, 2019.

A sensitivity analysis of tax credit was performed considering a variation of macroeconomics assumptions, operating performance and liquidity events. In this way, considering the results of studies performed, which indicates that it is probable that there will be taxable income to use the deferred income and social contribution taxes balance.

Impairment test - Deferred taxes

The Company's management constantly evaluates the ability to use its tax credits. In this direction, CSN periodically updates a technical study to demonstrate if the generation of future taxable profits support the realization of tax credits and, consequently support the realization of tax credits, the maintenance on the balance sheet or the constitution of a provision for loss in the realization of these credits.

This study is prepared at Entity level, in accordance with the Brazilian tax legislation, and is performed considering the Parent company’s projections, which is the entity that generates a significant amount of tax credits, mainly, temporary differences. The parent company covers the following businesses:

• Steel Brazil (steel); and

•Cement

The deferred tax assets on tax losses and temporary differences refers mainly to the following:

	Nature	Description
	Tax losses	The Company incur tax losses at the parent company level, because of financial expenses over its leverage, since it holds substantially all loans and financings of CSN group and presented a taxable income in 2018.
Temporary differences	Foreign exchange differences	Since 2012, the Company has opted for the taxation of exchange differences on a cash basis. As a result, taxes are due and expenses are deductible when the underlying asset or liabilities is settled.
	Losses on Usiminas shares	Changes in investments in Usiminas shares are recognized on an accrual basis, but the event that generates taxation or deductibility will only occur at the time of divestment.
	Other provisions	Other provisions are recognized on an accrual basis, but their taxation occurs only at the time of their realization, such as provisions for contingencies, impairment losses, environmental liabilities, etc.

The study prepared is based on the Company business plan of on a long-term basis, reasonably estimated by management and considered several scenarios which vary according to different macroeconomic and operating assumptions.

The model for projection of taxable profit considers two main indicators:

· Pre-Tax Profit, reflecting our projected EBITDA plus depreciation, other income and expenses and financial income (expenses); and

· Taxable Profit, which is our pre-tax profit plus (minus) expenses and income items that are taxable at a time different from the time obtained on an accrual basis (temporary differences).

In addition, a sensitivity analysis of tax credits utilization considering a variation in macroeconomic assumptions, operational performance and liquidity events took place.

A significant aspect to be considered in the analysis is the fact that CSN has presented recent tax losses mainly due to the deterioration of the Brazilian political and macroeconomic environment, as well as the growth of its financial leverage. These two aspects combined led to an imbalance between the financial and operating results of the Parent company.

Within this context, the Company works with a business plan to rebalance between the financial and operating results of the Parent company, whose main measures are:

· Expansion of disinvestment efforts;

· Reduction of financial leverage;

· Improvement in operating results due to increased sales volume, better prices of its products and efficiency in controlling production costs and

· Reprofiling of the Parent company's indebtedness, with negotiations to extend the amortization periods and decentralization of debt through redirection of contracts to subsidiaries according to the nature and application of resources.

With the aforementioned measures already in execution, the Company's management expects to retake high profitability rates. Accordingly, management considers that the gradual recognition of tax credits, using at first a time of projections of less than 10 years, better reflects the expectation of utilization of the credits recognized in the Company's tax books. As a result of the study, the Company reversed during 2019 R$2,361,362 of the loss recorded in previous years, with a balance of deferred fixed assets recognized in the amount of R$3,258,542 in the Parent Company, as of December 31, 2019.

The provision for tax, social security, labor, civil and environmental risks was estimated by Management and is mainly based on the legal counsel’s assessment. Only lawsuits for which the risk is classified as probable loss are provisioned. In addition, tax liabilities arising from actions taken at the initiative of the Company, plus SELIC interest (Special Settlement and Custody System).

Tax lawsuits

The main lawsuits that are considered by the external legal advisors as probable loss, which CSN or its subsidiaries are parties are as follows: (i) ISS tax assessments notices; (ii) Differences between calculated and paid ICMS; (iii) Consignment action for payment of social security contributions; (iv) requests for compensation not approved due to the lack of credit rights.

Labor lawsuits

As of December 31, 2019, the Group is a defendant in 7,590 labor lawsuits. Most of the claims relate to subsidiary and/or joint liability, salary equalization, health hazard premiums and hazardous duty premiums, overtime pay, health care plan, indemnity claims resulting from alleged occupational diseases or on-the-job accidents, breaks between working hours, and differences in profit sharing from 1997 to 1999 and from 2000 to 2003.

During the year ended December 31, 2019 there were addition or write-off movements in labor lawsuits arising from the definite conclusion and the constant revision of the Company’s accounting estimates related to the provision for contingencies that take into consideration the different nature of the claims made, as required by the Company’s accounting policies.

Civil lawsuits

Among the civil lawsuits in which the Company is a defendant are claims for compensation. Generally, these lawsuits result from work accidents, occupational diseases and contractual litigation related to the industrial activities of the Group, real estate actions, healthcare plan.

Environmental lawsuits

Among the environmental administrative / judicial proceedings in which the Company is a defendant include mainly administrative proceedings for alleged environmental irregularities and the regularization of environmental licenses; at the judicial level, the Company is a party to actions collecting the fines imposed for such alleged environmental irregularities and public civil actions claiming regularization with compensation, in most cases claiming environmental recovery. In general, these proceedings arise from alleged impacts to the environment related to the Company’s industrial activities.

The environmental processes are highly complex to estimate the value at risk, because they should be taken into consideration, among various aspects, procedural development, the extent of any damage and projected repair costs.

There are other environmental processes for which it is not yet possible to assess the risk and contingency amount due to the aforementioned complexity of estimation, the peculiarities of the matters involving them and also their procedural stages. The main environmental judicial and administrative procedures are listed below:

· In 2018, the Company celebrated TAC 07/2018, which aims to adopt environmental improvements within the scope of the UPV. The obligations of TAC 07/2018 are linked to the Environmental Operating Authorization (“AAF”) nºIN 002019, valid until October 2024, whose purpose is to authorize the regular operation of the UPV during compliance with TAC 07/2018.

· In July 2012, the Public Ministry of the State of Rio de Janeiro, (“Ministério Público do Estado do Rio de Janeiro” or “MPE/RJ”) and the Public Federal Ministry (“Ministério Público Federal” or “MPF”) filed a separate public civil action in the state and Federal Courts alleging, in existence of supposed contaminated area in the Condominium Volta Grande IV. In view of the conflict of jurisdiction to judge actions, the Superior Court of Justice (“Superior Tribunal de Justiça” or “STJ”) declared the jurisdiction of the Federal Court to prosecute and judge such actions. In brief, the MPF maintains that the company should (i) remove wastings left in industrial landfill areas in the city of Volta Redonda and (ii) transfer 750 residences of the Volta Grande IV condominium, also in the city of Volta Redonda. These requirements were denied by the Court, which determined the presentation of a schedule to investigate the area and, if necessary, to remediate the potential issues raised by the MPF. The aforementioned schedule was presented, and all the surveys performed during the investigation including the risk assessment and intervention plan were concluded in April 30, 2014. Also, there are actions initiated by owners of the residential condominium mentioned above to be reimbursed for material and moral damages, not yet judged.

· In January 2014, it was distributed an Annulment Action with the purpose of declaring the nullity of an Assessment Notice issued by INEA for the alleged contamination of the soil and groundwater in the Volta Grande IV Condominium. The penalty was a simple fine, in the amount of R$35 million. The request for the preliminary suspension of the chargeability of the debt was not assessed, which is why INEA filed a Tax Enforcement Action. Declared connection between actions. An application for suspension of the procedure was filed until the conclusion of the investigation in the ACP Volta Grande IV.

· With regards to other supposedly contaminated areas in Volta Redonda, the Public Ministry initiated three public civil actions claiming for environmental remediation and indemnification related to certain areas denominated Marcia I, II, III and IV, Wandir I and II and Reciclam. Regarding to Marcia I, the phase of producing evidence has ended and is being analyzed for judgment. The other claims are at initial stage and CSN are currently performing environmental studies that will determine the extent of possible environmental damages related to soil contamination, as well as the action plan to fulfill with the legislation in force. As soon as the studies are concluded, they will be presented and added to the pleadings.

· In 2015, the Public Federal Ministry initiated a public civil action against CSN claiming for the adequacy and regularization for the emission of particles from the UPV and the stoppage of its operations. According to CONAMA Resolution n. º 436/2011, the companies have to adjust the emission of particles to match to the new legal standards required by December 2018, which should be compatible with INEA the schedule of actions and measures foreseen in TAC 07/2018.

· In 2016, CSN were mentioned in public civil action proposed by the Public Federal Ministry and the Public Ministry of the State of Rio de Janeiro in relation to a supposedly irregular waste deposit in the landfill area named "Aterro Panco". The claimings are for the recovery of degraded areas, compensation for damages to fauna and flora and to human health, as well as indemnification for material and moral damages caused to the environment.

· In 1988, the Public Federal Ministry initiated a public civil action against CSN for a supposedly environmental contamination and pollution of the Paraiba do Sul river supposedly caused by our industrial activities of UPV. In 1995, the court determined the meeting of cases No. 15,497; 17,563; No. 7,304; and, No. 7,624, in view of the connection characterized and determined the joining of the four actions.

· The Federal Regional Court of the Second Region maintained the first instance conviction, reiterating the Company's obligation to compensate for possible environmental damage caused to the ecosystem. The Company appealed to the Superior Court of Justice (STJ), which accepted the appeal and annulled the previous decisions, determining the return of the records to the 1st Instance to resume the process.

· In 2010, a civil investigation was launched to verify (i) the environmental requirements for the CSN project in the city of Arcos (cement plant); (ii) monitoring and mitigation of the environmental impacts of our productive activities; (iii) conformity of the conditions our environmental licenses, including the creation of a museum within the Corumbá ecological station and the creation of a Private Reserve of Natural Heritage; and (iv) measures for preservation of cultural heritage and adoption of compensatory measures. In February 2, 2011 a Term of Undertaking was signed (“TAC”) to assure the fulfillment of the obligations raised by the Public Ministry. In December 2019, the TAC's final filing and settlement of obligations, without the payment of fines by CSN, was ratified by the Council of the Public Ministry.

· In 2009 and 2010, we signed Judicial Agreements (“TAJ”) with the Public Federal Ministry to recover environmental liabilities caused by our coal mining activities in the Southeast of Santa Catarina until the 90’s. The environmental liabilities reached by the TAJ include the restoration of certain degraded areas. In March 2018, the parties renegotiated a new agreement, with the extension of the construction schedule until 2030, which was legally approved on 06/06/18. The Company is currently negotiating with the Public Federal Ministry the suspension of the TAJ terms for trading and adjusting the obligations and planned compensatory measures.

· In July 2018, the Company and Harsco Metals ("Harsco"), a contracted company, were named in a new public civil action jointly filed by the Federal Public Ministry and the Public Prosecutor's Office of the State of Rio de Janeiro, due to the irregular deposit of waste (steel slag) in the area called "Slag Processing Yard". The decision issued established a certain limitation in the monthly dispatch of the slag to the said yard, reduction of the height of the piles, removal of the excess of the stored material, which finally had its effects suspended by preliminary decision. The Company and Harsco have been looking for alternatives to solve this problem and are working on a plan of action with a feasible schedule, due to the concern with the impacts that can be generated by the abrupt removal of the yard material within the deadline established in the preliminary decision.

· In January 1995, in the Municipality of Volta Redonda/RJ (“MVR”), the ACP was filed claimed to CSN to comply with 26 items of Compensatory Environmental Programs. After the dispute, the parties entered into Transaction (1995), establishing CSN's effective obligations, as well as environmental compensation, ratified in court by judgment. The Municipality of Volta Redonda disagreed about the approved agreement and in 2015 the process of liquidation of unfulfilled obligations was initiated. On December 27, 2018, a new agreement was signed between CSN and the MRV, to put an end to the legal dispute, through reciprocal concessions from the parties, with the MVR expressly waiving the right on which the lawsuit is based and to CSN an additional investment in the amount of R$21 million, with 30% of this amount being allocated to services of environmental interest, preservation works, improvement and recovery of the quality of the environment of Volta Redonda. In 2019, the agreement signed between CSN and MVR was approved with the effective disbursement by CSN of R$ 25MM, following the appellate prosecutor's office, which is awaiting judgment.

· In August 2017, CSN initiated an annulment action against the tax assessment notice that imposed a fine on CSN (R$25 million – updated until December/19), for alleged water pollution in the Paraíba do Sul River, with discharge of effluent from the ETE (Effluent Treatment Station) of Blast Furnace # 2, due to accident occurred on 11/27/2010. The enforceability of the fine is suspended by virtue of an injunction granted in a writ of mandamus until final decision of the appeal phase that discusses the guarantee offered to the court (suitable guarantee) for the grant of guardianship.

· In December 2019, a Public Civil Action was initiated against Sepetiba TECON and INEA aiming at suspending the environmental licensing processes of the Sepetiba TECON container terminal until the study of the environmental support capacity of Sepetiba Bay is carried out, and the INEA to refrain from licensing new ventures or potentially polluting activities on the site, which may harm the socio-environmental balance of the Bay and the preservation of marine fauna. Sepetiba TECON became aware of the action through news published on the MPF website. On 12/19/19, the court rejected the request for urgent relief requested by the MPF, as well as the Federal Union and IBAMA's decision was determined. Citation is awaited.

· In June 2019, CSN filed a lawsuit against the INEA Notification, which determined the suspension of operations for handling solid bulk in TECON due to the alleged lack of activity forecast in the object of the respective Operation License. A preliminary injunction was granted to suspend the effects of the Notification and allow the continuation of the solid bulk handling operation until the final judgment of the action. Decision confirmed on appeal.

· In relation to mining issues, with the occurrence of the accident involving a Brazilian company in November 2015, the State of Minas Gerais initiated several civil inquiries aimed at investigating companies in the mining segment, based on the State Dam Inventory released in 2014. These procedures are intended to investigate structures that do not have technical stability guaranteed by an external auditor, or whose stability has not been attested due to the lack of documents or technical data. In August 2016, the Company was cited in a similar public civil action, in relation to the structure of Dique do Engenho Dam. Documents were submitted to the state authorities that prove the stability and safety of the said dam. It is expected that this case will also be closed, for the same reasons as the previous one.

25. SEGMENT INFORMATION

According to the Group´s structure, the businesses are distributed and managed in five operating segments as follows:

· Steel

The Steel Segment consolidates all the operations related to the production, distribution and sale of flat steel, long steel, metallic containers and galvanized steel, with operations in Brazil, United States, Portugal and Germany. The Segment supplies the following markets: construction, steel containers for the Brazilian chemical and food industries, home appliances, automobile and OEM (motors and compressors). The Company’s steel units produce hot and cold rolled steel, galvanized and pre-painted steel of great durability. They also produce tinplate, a raw material used to produce metallic containers.

Overseas, Lusosider, which is based in Portugal, produces cold rolled steel and galvanized steel. CSN LLC in the U.S.A. meets local market needs, import and export of steel products. In January 2012, CSN acquired Stahlwerk Thüringen (SWT), a manufacturer of long steel located in Unterwellenborn, Germany. SWT is specialized in the production of shapes used for construction.

In January 2014 the production of long steel products started in Brazil and consolidates the company as a source of complete construction solutions, complementing its portfolio of products with high value added in the steel chain.

· Mining

This segment encompasses the activities of iron ore and tin mining.

The high quality iron ore operations are located in the Iron Quadrilateral in Minas Gerais, which has its own mines and sells third party iron ore.

At the end of 2015, CSN and the Asian Consortium formalized a shareholders' agreement for the combination of assets linked to iron ore operations and the related logistics structure, forming a new company that has focused in mining of the Group activities from December 2015. In this context, the new company, currently named CSN Mineração S.A., holds the TECAR arraignment, the Casa de Pedra mine and all the shares of Namisa, which was incorporated on December 31, 2015. CSN still owns 100% of Minérios Nacional which includes the mines of Fernandinho (operational), Cayman and Pedras Pretas (mineral resources), all located in Minas Gerais.

Moreover, CSN controls the Estanho de Rondônia S.A., company with mining units and tin casting, in the state of Rondonia.

· Logistics

i. Railroad

CSN has equity interests in three railroad companies: MRS Logística, which manages the former Southeast Network of Rede Ferroviária Federal S.A. (RFFSA), Transnordestina Logística S.A. and FTL - Ferrovia Transnordestina Logística S.A., which has the concession to operate the former Northeast Network of the RFFSA in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas.

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

a) MRS

The railroad transportation services provided by MRS are fundamental to the supply of raw materials and the shipment of final products. The total amount of iron ore, coal and coke consumed by the Presidente Vargas Mill as well as part of the steel produced by CSN for the domestic market and for export are carried by MRS.

The Southeast Brazilian railroad system, encompassing 1,674 kilometers of tracks, serves the tri-state industrial area of São Paulo-Rio de Janeiro-Minas Gerais, in the southeast region, linking the mines located in Minas Gerais to the ports located in São Paulo and Rio de Janeiro, and the steel mills of CSN, Companhia Siderúrgica Paulista, or Cosipa, and Gerdau Açominas. Besides serving other customers, the railroad system carries iron ore from the Company’s mines in Casa de Pedra, Minas Gerais, and coke and coal from the Itaguaí Port, in Rio de Janeiro, to Volta Redonda/RJ, and carries CSN’s export products to the ports of Itaguaí and Rio de Janeiro.

b) TLSA and FTL

TLSA and FTL hold the concession of the former RFFSA’s Northeast Network. The Northeast Network totals 4,238 km, divided into two sections: i) Network I, which comprises the São Luiz–Mucuripe, Arrojado–Recife, Itabaiana–Cabedelo, Paula Cavalcante–Macau and Propriá–Jorge Lins (Network I); and ii) Network II, which comprises the sections of Missão Velha–Salgueiro, Salgueiro, Salgueiro –Trindade, Trindade– Eliseu Martins, Salgueiro–Porto de Suape and Missão Velha–Porto de Pecém.

In addition, it connects to the main ports in the region, thereby offering an important competitive advantage through opportunities for combined transport solutions and logistics projects tailored to customer needs.

II. Port Logistics

The Port Logistics Segment consolidates the operation of the terminal built in the privatization period after the law of modernization of the ports (law 8.630/1993) that permits to transfer the port logistics activities to the private sector. The Sepetiba terminal features complete infrastructure to meet all the needs of exporters, importers and ship owners. Its installed capacity exceeds that of most other Brazilian terminals. It has mooring berths and a huge storage area, as well as the most modern and appropriate equipment, systems and intermodal connections.

The Company’s constant investment in projects in the terminals consolidates the Itaguaí Port Complex as one of the most modern in Brazil.

· Energy

CSN is one of the largest industrial consumers of electric power in Brazil. As energy is fundamental in its production process, the Company invests in assets for generation of electric power to guarantee its self-sufficiency. These assets are as follows: Itá hydroelectric power plant, in the State of Santa Catarina, with rated capacity of 1,450 MW, where CSN has a share of 29.5%; Igarapava hydroelectric power plant, Minas Gerais, with rated capacity of 210 MW, in which CSN holds 17.9% of the capital; and a thermoelectric co-generation Central unit with rated capacity of 238 MW, which has been operating at the UPV since 1999, that uses the residual gases produced by the steel mill itself.

· Cement

The cement division consolidates the cement production, distribution and sale operations, which use the slag produced by the blast furnaces of the Usina Presidente Vargas in Volta Redonda/RJ.

The Company produces clinker in Arcos/MG, using limestone from own mine and also two cement mills in additions to the mills that already operate in Volta Redonda/RJ.

The information presented to Management regarding the performance of each business segment is generally derived directly from the accounting records, combined with some intercompany allocations.

· Sales by geographic area

Sales by geographic area are determined based on the customers’ location. On a consolidated basis, domestic sales are represented by revenues from customers located in Brazil and export sales are represented by revenues from customers located abroad.

· Results by segments

As of fiscal year 2013, the Company ceased to proportionally consolidate the jointly controlled companies MRS and CBSI. For the purposes of preparing and presenting information by business segment, Management decided to maintain the proportional consolidation of the jointly controlled companies, as historically presented. For purposes of reconciling the consolidated result, the values of these companies are eliminated in the column “Corporate expenses / elimination.

· Adjusted EBITDA

Adjusted EBITDA is the principal measurement through which the chief operating decision maker assesses the segment performance and the capacity to generate recurring operating cash, consisting of profit for the year less net finance income (expenses), income tax and social contribution, depreciation and amortization, equity in results, results of discontinued operations and other operating income (expenses), plus the proportionate EBITDA of joint ventures.

Even though it is an indicator used in segment measurement, EBITDA is not a measurement recognized by accounting practices adopted in Brazil or IFRS, it does not have a standard definition, and may not be comparable with measurements using similar names provided by other companies.

As required by IFRS 8, the table below shows the reconciliation of the measurement used by the chief operating decision maker with the results determined using the accounting practices:

		Consolidated
	12/31/2019	12/31/2018
Net income (loss) for the year	2,244,511	5,200,583
Depreciation/Amortization/Depletion (note 22)	1,421,704	1,175,107
Income tax and social contribution (note 14)	(833,778)	250,334
Financial income (expenses) (note 24)	2,131,184	1,495,643
EBITDA	4,963,621	8,121,667
Other operating income (expenses) (note 23)	1,903,081	(2,705,337)
Equity in results of affiliated companies (note 8b)	(125,715)	(135,706)
Proportionate EBITDA of joint ventures	510,072	568,045
*Adjusted EBITDA ()**	7,251,059	5,848,669

(*) The Company discloses its adjusted EBITDA net of its share of investments and other operating income (expenses) because it understands that these should not be considered in the calculation of recurring operating cash generation.

26. EMPLOYEE BENEFIT

The pension plans granted by the Company cover substantially all employees. The plans are administered by Caixa Beneficente dos Empregados da CSN (‘CBS”), a private non-profit pension fund established in July 1960 which has as members the employees (and former employees) of the Company and some subsidiaries who joined the fund through an agreement, and the employees of CBS itself. The Executive Officers of CBS is formed by a CEO and two other executive officers, all appointed by CSN, which is the main sponsor of CBS. The Decision-Making Board is the higher decision-making and guideline-setting body of CBS, composed by the president and ten members, six chosen by CSN, and four elected by the fund’s participants.

Until December 1995, CBS Previdência administered two defined benefit plans based on years of service, salary and Social Security benefits. On December 27, 1995 the then Private Pension Secretariat (“SPC”) approved the implementation of a new benefit plan, effective beginning that date, called Mixed Supplementary Benefit Plan (‘Mixed Plan”), structured in the form of a variable contribution plan that was discontinued on September 16, 2013. As of that date, all new employees must join the CBSPrev Plan, structured in the defined contribution modality, created also in September 2013.

As of December 31, 2019, CBS had 35,547 participants (34,985 as of December 31, 2018), of whom 22,091 were active contributors (20,872 as of December 31, 2018), 13,139 were retired employees (13,454 as of December 31, 2018), and 317 were related beneficiaries (659 as of December 31, 2018). Out of the total participants as of December 31, 2019, 10,616 (11,063 as of December 31,2018) belonged to the defined benefit plan, 11,111 (11.845 as of December 31,2018) to the mixed plan, 841 (1,028 as of December 31, 2018) to the CBSPrev Namisa plan, and 12,979 (11,049 as of December 31, 2018) to the CBSPrev plan.

The plan assets of CBS are primarily invested in repurchase agreements (backed by federal government securities), federal government securities indexed to inflation, shares, loans and real estate. As of December 31, 2019, CBS held 1,870,652 common shares of CSN (37,084,031 as of December 31,2018). The total plan assets of the entity amounted to R$5.5 billion as of December 31, 2019 (R$5.3 billion as of December 31, 2018). The administrators of the CBS to match plan assets with benefit obligations payable on a long-term basis. Pension funds in Brazil are subject to certain restrictions regarding their capacity for investment in foreign assets and, therefore, these funds invest mainly in Brazilian securities.

Guarantee Funds are considered to be the available and investment assets of the Benefit Plans, not including the amounts of debts contracted with sponsors

For the defined benefit plans, called “35% of the average salary” and “average salary supplementation plan”, the Company holds a financial guarantee with CBS Previdência, the entity that administers said plans, to ensure their financial and actuarial balance, in the event of any future actuarial loss or actuarial gain.

As provided for in the prevailing law that governs the pension fund market, for the last 4 years ended (2016, 2017, 2018 and 2019), CSN did not have to pay the installments because the defined benefit plans posted actuarial gains for the period.

26.a) Description of the pension plans

Plan covering 35% of the average salary

This plan began on February 1, 1966 and is a defined benefit plan aimed at paying pensions (for length of service, special situations, disability or old age) on a lifetime basis, equivalent to 35% of the adjusted average of the participant’s salary for the last 12 months. The plan also guarantees the payment of sickness benefits to the participants licensed by the Official Social Security and guarantees the payments of savings fund, funeral allowance and pecuniary aid. This plan was discontinued on October 31, 1977 when took effect the average salary supplementation plan.

Average salary supplementation plan

This plan began on November 1, 1977 and is a defined benefit plan aimed at complementing the difference between the adjusted average of the participant’s salary for the last 12 months and the Official Social Security benefit for retirement, also on a lifetime basis. As in the 35% plan, there is coverage for sickness benefit, death and pension. This plan was discontinued on December 26, 1995 with the creation of the mixed supplementary benefit plan.

Mixed supplementary benefit plan

This plan began on December 27, 1995 and is a variable contribution plan. Besides the scheduled retirement benefit, it also covers the payment of risk benefits (pension paid while the participant is still working, disability compensation and sick/accident pay). Under this plan, the retirement benefit is calculated based on the amount accumulated by the monthly contributions of the participants and sponsors, as well as on each participant’s option for the manner in which they receive them, which can be lifetime (with or without continuity of pension for death) or through a percentage applied to the balance of the benefit-generating fund (loss for indefinite period). After retirement is granted, the plan takes on the characteristics of a defined benefit plan if the participant has chosen to receive his benefit in the form of monthly income for life. This plan was discontinued on September 16, 2013 when the CBS Prev plan became effective.

CBS Prev Plan

The new CBS Prev Plan, which is a defined contribution plan, started on September 16, 2013. Under this plan, the retirement benefit is determined based on the accumulated amount by monthly contributions of participants and sponsors. To receive the benefit, each participant can opt for: (a) receiving part in cash (up to 25%) and the remaining balance through a monthly income through a percentage applied to the benefit-generating fund, not being applicable to death pension benefits, or (b) receive only a monthly income through a percentage applied to the benefit-generating fund.

With the creation of the CBS Prev Plan, the mixed supplementary benefit plan was discontinued for the entry of new participants as from September 16, 2013.

CBSPREV Namisa Plan

It is a Defined Contribution plan with benefits of risks during the activity (projection of the balances in case of disability or death and sickness / accident allowanced). It has been in operation since January 6, 2012, when it was created exclusively for the employees of Nacional Minérios S.A. After the corporate reorganization, which took place in 2016, other Sponsors joined this Plan, among them CSN Mineração S.A.

Under this plan, all the benefits offered are calculated based on the accumulated amount from the monthly contributions of participants and sponsors and are paid through a percentage applied to the balance of the benefit generating fund. The CBSPREV Namisa Plan has been closed to new participants since July 2017 and is in the process of being extinguished due to the total withdrawal of sponsorship.

26.b) Investment policy

The investment policy establishes the principles and guidelines that will govern the investments of funds entrusted to the entity, in order to foster the security, liquidity and profitability required to ensure equilibrium between the plan’s assets and liabilities based on an ALM (Asset Liability Management) study that takes into consideration the benefits of participants and beneficiaries for each plan.

The investment plan is reviewed annually and approved by the Decision-Making Board considering a five-year horizon, as established by resolution CGPC 7 of December 4, 2003. The investment limits and criteria established in the policy are based on Resolution 3,792/09 published by the National Monetary Council (“CMN”).

26.c) Employee benefits

The actuarial calculations are updated at the end of each annual reporting period by outside actuaries and presented in the financial statements pursuant to CPC33(R1)/IAS19 - Employee Benefits.

27.b) Projects and other commitments

· Transnordestina project

The Transnordestina project which corresponds to rail network II of the Northeast Railway System, includes building 1,753 km of new, next-generation, wide-gauge tracks. The project posts an evolution of 52% progress which was expected to completion for 2017, completion period currently under discussion with the responsible agencies.

The Company expects that the investments will permit Transnordestina Logística S.A. (“TLSA”), the concessionaire that holds the Transnordestina project, to transport of several products, such as iron ore, limestone, soy, cotton, sugarcane, fertilizers, oil, and fuel. The concession will expire in 2057 and can be terminated before this date if the minimum return agreed with the Government is reached. Transnordestina has already obtained the required environmental licenses and in certain regions the project is at an advanced implementation stage.

The sources of financing for the project are: (i) financing granted by Banco do Nordeste/ FNE and the BNDES, (ii) debentures issued by FDNE, (iii) contracts for use of the permanent way and (iv) contribution of capital by CSN and public shareholders. The approved construction investment is R$7,542,000 and the balance of disbursable funds will be adjusted using the IPCA as from April 2012. If additional resources are needed, they will be provided by CSN and/or third parties under contracts for use of the permanent way.

The approved budget amount is composed as follows: Missão Velha-Salgueiro: R$0.4 billion, Salgueiro-Trindade: R$0.7 billion, Trindade-Eliseu Martins: R$2.4 billion, Missão Velha-Porto de Pecém: R$3 billion, Salgueiro-Porto de Suape: R$4.7 billion, amounting R$ 11.2 billion. The project is currently in the process of budged adjustment and the proposed amount is R$13.2 Billion.

The Company guarantees 100% of TLSA’s financing granted by Banco do Nordeste/FNE and the BNDES, and 50.97% of the debentures issued by FDNE (includes the corporate guarantee of 48.47%, a letter of guarantee of 1.25% to BNB and corporate guarantee of 1.25% to BNB). Under the FDNE charter, approved by Federal Decree nº 6,952/2009, and the Investment Agreement entered into with the shareholders/ public financiers, up to 50% of the debentures may be converted into TLSA shares.

The Court of Auditors of the Union - TCU through a protective order issued in May 2016, regarding the case TC 012.179/2016, suspended new transfers of public resources to TLSA from Valec Engenharia, Construções e Ferrovias S.A., Fundo de Investimento do Nordeste – FINOR, Fundo Constitucional de Financiamento do Nordeste – FNE, Fundo de Desenvolvimento do Nordeste – FDNE, Banco Nacional de Desenvolvimento Econômico e Social – BNDES and BNDES Participações S.A.– BNDESPar. After filing an appeal against the protective order and providing the necessary explanations, in June 2016 the order issued by TCU was unanimously revoked by the members of this court, with the continuity of planned investments having been restored.

Version: 1

By means of another protective order issued in January 2017, relating to the case TC 012.179/2016, the Court of Auditors of the Union suspended new transfers of public resources to TLSA by Valec Engenharia, Construções e Ferrovias S.A., Fundo de Investimento do Nordeste – FINOR, Fundo Constitucional de Financiamento do Nordeste – FNE, Fundo de Desenvolvimento do Nordeste – FDNE, Banco Nacional de Desenvolvimento Econômico e Social – BNDES and BNDES Participações S.A.– BNDESPar. The Company has provided the required clarifications to the TCU and has acted firmly in order that the decision can be repealed soon, and the flow of investments planned can be restored.

The Company concluded in December / 2019, according to the scheduled schedule, the engineering deliveries referring to the revision of the projects of the sections to be executed, as well as the survey of the services already executed in the sections in progress and completed (“as built”), in a way to allow the validation of the regulatory budget and the preparation of a revisited schedule. The Company awaits the analysis to be carried out by the regulatory agency, whose management's expectation is that it will be carried out during the first half of 2020

There is an administrative procedure with the ANTT (National Land Transportation Agency) which evaluates the regular compliance with the obligations of the Concession Agreement corresponding to System II by Concessionaire TLSA. ANTT’s technical area, in a unilateral opinion, understood that non-compliance with the contractual obligations by the Concessionaire is evidenced. The technical area’s opinion is under evaluation and, if the irregularity is proven, ANTT may open new process to apply the applicable penalties, among them, forfeiture. The procedure is in fact finding phase and until the moment there is no final decision on the merit.

· FTL – Ferrovia Transnordestina Logística S.A. (Operational rail network)

In relation to the rail network I, operates by Ferrovia Transnordestina Logística S.A.(“FTL”) - there is an administrative procedure before the National Agency for Land Transportation (“ANTT”) that analyzes the regular fulfillment of the obligations of the Concession Agreement by the Concessionaire FTL. In view of a unilateral analysis, ANTT informed that FTL would have failed to comply with the TAC (Undertaking agreement) signed in 2013 as a result of the non-compliance with the production target for 2013. In this context, the agency proposed to the Union the declaration of the expiry of the FTL Concession Contract and the initiation of an administrative proceeding within the scope of the Superintendence of Infrastructure and Railroad Cargo Transport Services - SUFER. The Company continues to rely on ANTT's positioning.

28. INSURANCE

Aiming to properly mitigate risk and in view of the nature of its operations, the Company and its subsidiaries have taken out several different types of insurance policies. Such policies are contracted in line with the Risk Management policy and are similar to the insurance taken out by other companies operating in the same lines of business as CSN and its subsidiaries. The risks covered under such policies include the following: Domestic Transportation, International Transportation, Life and Casualty, Health, Vehicles Fleet, D&O (Civil Liability Insurance for Directors and Officers), General Civil Liability, Engineering Risks, Named risks, Export Credit, guarantee insurance and Port Operator’s Civil Liability.

In 2019, after negotiation with insurers and reinsurers in Brazil and abroad, an insurance policy was issued of Operational Risk of Property Damages and Loss of Profits, with effect from March 31, 2019 to March 31, 2020. Under the insurance policy, the LMI (Maximum Limit of Indemnity) is US$600 million and deductibles in the amount of US$385 million for material damages and 45 days for loss of profits and covers the following Company’s units and subsidiaries: Presidente Vargas Steelworks, CSN Mineração and Sepetiba Tecon.

The risk assumptions adopted, given their nature, are not within the scope of an audit of the financial statements, consequently not audited by our independent auditors.

If the issuer has disclosed, in the last 3 fiscal years, projections over the progress of its indicators:

a) Inform which were being replaced by new projections and which were being repeated.

Estimates maintained:

CSN maintains an estimated iron ore sales volume of 33 Mton in 2020, 31.2Mton in 2021, 36.6Mton in 2022 and 38Mton in 2023.

b) In relation to the projections for periods that have already occurred, compare the projection data with the performance indicators, clearly indicating the reasons that led to deviations in the projections.

Adjusted EBITDA 2019 was 3% below the projected R $ 7.5 billion, due to the lower mining result by Platts being below our budget, as well as freight above projections.

CSN estimated leverage measured by the net debt to adjusted EBITDA ratio close to 3.5 times at the end of 2019, when we reached 3.74 times, that is, materially below our initial estimates due to the exchange rate variation that strongly influenced our debt in dollar, CAPEX slightly higher than expected, as well as lower than expected mining results due to the increase in freight and the drop in Platts from the third quarter.

Iron ore production was 3% below the projection of 33Mton due to rains in the southeastern region in November and December 2019.

CSN estimates iron ore production volume at 33 Mton by 2020, 31.2 Mton in 2021, 36.6 Mton in 2022 and 38.0 Mton in 2023. The expected increase in production in 2020 is due to adjustments in the mining plan.

Follow-up and changes to projections disclosed

The result of the fourth quarter of 2019 does not bring any material variation to the results projections previously presented, which can therefore be maintained.

Independent Auditor’s Report on the Financial Information

To the

Shareholders, Directors and Management of

Companhia Siderúrgica Nacional

São Paulo – SP

Opinion

We have audited the accompanying individual and consolidated financial statements of Companhia Siderúrgica Nacional (“Company”), identified as Parent and consolidated, respectively, which comprise the balance sheet as of December 31, 2019, and the income statement, statement of comprehensive income, statement of changes in equity, and statement of cash flows for the year then ended, and notes to the financial statements, including a summary of significant accounting policies.

In our opinion, the individual and consolidated financial statements present fairly, in all material respects, the individual and consolidated financial position of Companhia Siderúrgica Nacional as of December 31, 2019, and its individual and consolidated financial performance and individual and consolidated cash flows for the year then ended, in accordance with the accounting practices adopted in Brazil and the International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Board (IASB).

Basis for opinion

We conducted our audit in accordance with Brazilian and International Standards on Auditing (ISAs). Our responsibilities under those standards are further described in the “Auditor’s responsibilities for the audit of the individual and consolidated financial statements” section of our report. We are independent of the Company and its subsidiaries in accordance with the relevant ethical requirements set forth in the Code of Ethics for Professional Accountants and the professional standards issued by the Federal Accounting Council and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Emphasis of matter

Ability of the jointly controlled subsidiary Transnordestina Logística S.A. to continue as a going concern

We draw attention to note 8.d) to the individual and consolidated financial statements, which describes the percentage of completion of the new railway network by the jointly controlled subsidiary Transnordestina Logística S.A. (TLSA), currently under construction and originally scheduled to be completed by January 2017, is currently being revised and discussed by the relevant regulatory bodies. The completion of the work under the project (and consequent start of operations) is contingent upon receiving ongoing financial contribution from TLSA´s shareholders and third parties. These events and conditions, together with other issues described in said Note indicate the existence of significant uncertainty that may raise significant doubt as to TLSA´s ability to continue as a going concern. Our opinion is not qualified regarding this matter.

Key audit matters

Key audit matters (KAM) are those matters that, in our judgment, were of most significance in our audit of the financial statements for the current period. These matters were addressed in the context of our audit of the individual and consolidated financial statements taken as a whole and in forming our opinion on such individual and consolidated financial statements, and, therefore, we do not provide a separate opinion on these matters. In addition to the matter described in the “Continuity of jointly controlled subsidiary Transnordestina Logística S.A. as a going concern” section, we determined that the matters described below are the key audit matters that should be communicated in our report.

1. Financial leverage and risk of liquidity and going concern (Notes 1 and 11)

Why the matter was determined to be a KAM

A substantial part of the funds and investments necessary for the development of the Company’s activities derives from financing. As of December 31, 2019, the amount of borrowings, financing and debentures with third parties, recognized in current and noncurrent liabilities amounted to R$24,198 million (Parent) and R$28,091 million (consolidated).

As the main item accounting for the high financial leverage, for financial instrument liabilities represented by borrowings, financing and debentures, Management plans to restructure debts and decrease the financial leverage by selling non-strategic assets (Note 11). In the current year, this matter was again considered a critical and risk area in our audit approach due to its relevance for the continuity of the Company’s operations and the materiality of the debts in relation to the financial statements as a whole. Additionally, borrowings, financing and debentures require, in some cases, compliance with covenants and other restrictive conditions which, if not met, may cause the individual and consolidated financial statements to be materially misstated.

How the matter was addressed in the audit of the individual and consolidated financial statements

Our audit procedures included, among others:

· Understand the policies and measures adopted by Management to manage and prepare the cash flow;

· Discuss, with Management, the business plan and actions taken to renegotiate debts;

· Evaluate the design of the internal control environment implemented by Management to control and recognize the liabilities arising from borrowings, financing and debentures;

· Test the changes in new capitalization and amortization, recalculate financial interest and evaluate the classification between current and noncurrent liabilities;

· Send external confirmation letters to confirm balances with creditors and trustees;

· Perform an analysis and adherence tests with respect to covenants and restrictive contractual clauses to confirm that the Company is compliant(and, in case of default, confirm that the effects thereof on the individual and consolidated financial statements were properly recorded);

· Verify if the criteria to meet accounting standards over discontinued operations and assets for sale were complied with by the Company’s Management;

· Analyze the disclosures required in the individual and consolidated financial statements.

Annual Financial Statements - December 31, 2019 – CIA SIDERURGICA NACIONAL

Version: 1

As a result of auditing procedures performed, we understand that the criteria and assumptions adopted by the Company to recognize borrowings, financing and debentures and its evaluation of the Company’s ability to continue as a going concern were appropriately addressed and disclosed in the context of the individual and consolidated financial statements taken as a whole.

2. Recoverable value of the investment in jointly controlled subsidiary (Note 8)

Why the matter was determined to be a KAM

The Company has an investment in jointly controlled subsidiary Transnordestina Logística S.A. (“TLSA”) as of December 31, 2019, including gain on loss of control, in the amount of R$1,460 million, whose recoverable value should be tested for impairment annually, as required by technical pronouncement CPC 01(R-1) – Impairment of assets. As mentioned in such note, the jointly controlled subsidiary performs impairment tests, which involves a high degree of subjectivity and judgment by Management, based on the discounted cash flow method, which considers several assumptions, such as discount rate, inflation projection, economic growth, among others. The Company, as an investor, also conducts its evaluation, under a method that considers the investee’s capacity to distribute dividends, named Dividend Discount Model, which considers the flow of dividends discounted at present value using the equity capital in addition to other metrics and risks factors that increase the discount rate used. Accordingly, in the audit of the current year, this matter was again considered an area of risk due to the uncertainty inherent in the process of determining the estimates and judgments involved in preparing future cash flows discounted to present value, such as projections of market demand, operating margins and discount rates that may significantly change the expected realization of the asset.

How the matter was addressed in the audit of the individual and consolidated financial statements

Our audit procedures included, among others:

· Evaluate the design of internal control environment implemented by Management related to impairment testing;

· Examine the analysis prepared by Management, supported by our internal specialists to verify the reasonableness of the model used in Management’s assessment;

· Ongoing challenge of the assumptions used by Management in order to corroborate if there are assumptions not consistent and/or that might be revised;

· Obtain an update and inquire the Company’s Management and TLSA’s executives of the progress of the discussions for the release of the funds by controlling shareholders to resume the constructions and release the funds by Federal Government agencies and related entities;

· Analyze the disclosures required in the individual and consolidated financial statements;

· Evaluate if the disclosures in notes are consistent with the information and representations obtained from Management.

Based on the procedures performed, we considered that the assumptions and methodologies used by the Company to evaluate the recoverable value of such assets are reasonable, and the information presented in the individual and consolidated financial statements is consistent with the information analyzed in our auditing procedures in the context of those individual and consolidated financial statements taken as a whole.

3. Realization of deferred tax assets (Notes 2.t, 14.b and 14.c)

Why the matter was determined to be a KAM

The Company and its subsidiaries have balances of deferred income tax and social contribution assets substantially related to tax losses, negative social contribution base and temporary differences arising from temporary provisions recognized. These balances of deferred taxes were recognized based on studies that contain projections of future taxable income. As of December 31, 2019, the amount of deferred tax assets recognized in noncurrent assets was R$3,259 million (Parent) and R$3,297 million (consolidated).

Considering that the annual evaluation for the recoverability of these assets involves, among others, the use of critical judgment, not always objective, which implies subjectivity in relation to the projections of results (such as taxable income, cash flow projections and future economic events, in addition to the fact that projects include estimates relating the performance of the Brazilian and global economy, taking into account sales volumes and prices and tax rates, among others), actual data and amounts may differ from the estimates.

Therefore, the use of different assumptions may significantly change the expected realization of these assets and may require the additional recognition of impairment on such assets, which would consequently impact the financial statements. Due to these aspects, this issue was considered a key audit matter.

How the matter was addressed in the audit of the individual and consolidated financial statements

We performed the following auditing procedures, among others:

· Evaluate the design of internal control environment implemented by Management related to the analysis of the impairment of deferred tax assets;

· Exam the analysis prepared by Management, supported by our internal specialists, to evaluate the logical and arithmetic adequacy of the cash flow projections as well as test the consistency of the key information and assumptions used in the projections of future taxable income and cash flows, by comparing the budgets approved by the Executive Board and the assumptions and market inputs;

· Discuss, with Management, the business plan and actions taken to renegotiate debts;

· Ongoing challenge of the assumptions used by Management in order to corroborate if there are assumptions not consistent and/or that might be revised;

· Examine, supported by our internal tax specialists, the calculation basis of the tax losses and negative social contribution base as well as of the temporary differences, and compare to the corresponding tax records;

· Analyze the disclosures required in the individual and consolidated financial statements.

Other matters

Statements of value added

The individual and consolidated statements of value added (“DVA”) for the year ended December 31, 2019, prepared under the responsibility of the Company’s Management, the presentation of which is required by Brazilian Corporate Law for public companies and considered supplemental information by IFRS, have been submitted to auditing procedures performed in conjunction with our audit of the Company’s financial statements. In forming our opinion, we evaluated if these statements are reconciled to the financial statements and accounting records, as applicable, and if its form and content are in accordance with the criteria defined in CPC 09 – Statement of Value Added. In our opinion, these statements of value added were appropriately prepared, in all material respects, according to the criteria defined in the technical pronouncement and are consistent in relation to the individual and consolidated financial statements taken as a whole.

Other information accompanying the individual and consolidated financial statements and auditor’s report thereon

The Company’s Management is responsible for this other information that is included in the Management Report.

Our opinion on the individual and consolidated financial statements does not cover the Management Report and we do not express any form of assurance conclusion thereon.

In connection with our audit of the individual and consolidated financial statements, our responsibility is to read the Management Report and, in doing so, consider whether this report is materially inconsistent with the financial statements or our knowledge obtained during the audit, or otherwise appears to be materially misstated. If we conclude, based on the work we have performed that there is a material misstatement in Management Report, we are required to report this fact. We have nothing to report in this regard.

Responsibility of Management and those charged with governance for the individual and consolidated financial statements

The Company’s Management is responsible for the preparation and fair presentation of the individual and consolidated financial statements in accordance with accounting practices adopted in Brazil and International Financial Reporting Standards (IFRS), issued by the International Accounting Standards Board (IASB), and for such internal control as Management determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the individual and consolidated financial statements, Management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting in preparing the financial statements, unless Management either intends to liquidate the Company or to cease operations, or has no realistic alternative to avoid doing so.

Those charged with the Company’s and its subsidiaries’ governance are those responsible for overseeing the financial reporting process in preparing the individual and consolidated financial statements.

Auditor’s responsibility for the audit of the individual and consolidated financial statements

Our objectives are to obtain reasonable assurance about whether the individual and consolidated financial statements, taken as a whole, are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with Brazilian and International Standards on Auditing, we exercise professional judgment and maintain professional skepticism throughout the audit. In addition, we:

· Identified and assessed the risks of material misstatement of the individual and consolidated financial statements, whether due to fraud or error, designed and performed audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve override of internal control, collusion, forgery, intentional omissions or misrepresentations;

· Obtained an understood of internal controls relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s and its subsidiaries’ internal controls;

· Evaluated the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by Management;

· Concluded on the appropriateness of management’s use of the going concern basis of accounting and based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the individual and consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern;

· Evaluated the overall presentation, structure and content of the financial statements, including the disclosures, and whether the individual and consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation;

· Obtained sufficient and appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the individual and consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit and, consequently, for the audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we may have identified during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements, including those regarding independence, and communicate to them all relationships and other matters that may reasonably be thought to bear on our independence and, where applicable, related safeguards.

From the matters communicated with those charged with governance, we determined those matters that were of most significance in the audit of the financial statements for the current year and are, therefore, the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.
