2015 MANAGEMENT REPORT

1- MESSAGE FROM MANAGEMENT

CSN is still facing challenges with optimism and confidence in the economic development and potential of Brazil, and it was in that spirit that we faced the difficulties during 2015.

Our mining operations hit records in Casa de Pedra, with shipments amounting to 28 million tons in 2015. We successfully implemented a cost reduction plan, transforming CSN into one of the world’s most competitive mining companies, and placing it in a position which allows us to overcome global market instabilities. In addition, Casa de Pedra had certifications confirmed for more than 6 billion tons of resources and 3 billion tons of reserves. In December, we completed the merger of CSN’s and NAMISA’s mining and associated logisitics assets, including the rights to operate the Tecar Port Terminal in Itaguaí (RJ) and the interest in MRS, creating a global company, Congonhas Minérios.

In the steel segment, we continued modernizing the Presidente Vargas Steelworks (UPV) in Volta Redonda (RJ), ensuring competitiveness and sustainability gains, with emphasis on the programs for revamping the coke batteries and one of the turbines in our Thermoelectric Center. The Waste Management System is another project of the Presidente Vargas Steelworks, which was recognized internationally during the Congress of the Latin American Steel Association (ALACERO), in the Best Available Techniques category, for its innovation and applicability.

The delivery of two new crushing facilities in Arcos (MG) represents the conclusion of an important step in the plan to reach total annual production capacity of 5.4 million tons of cement in the Southeast.

Finally, with regard to our financial management, we extended most of our debt maturities scheduled for 2016 and 2017 in order to improve the amortization profile and adjust the Company to the global risk scenario.

All these achievements show that, commited to respect to the environment and the communities where we operate, we have worked to improve CSN’s efficiency and competitiveness, always driven by the challenge of doing more, doing better, doing always.

Benjamin Steinbruch

Chairman of the Board of Directors

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 diversified range of high value-added steel products. Thanks to this integrated production system and exemplary management, CSN’s production costs are among the lowest in the sector where it operates.

In 2015, Presidente Vargas Steelworks produced 4.2 million tons of crude steel and 4.0 million tons of rolled steel. Steel sales, in turn, came to 5 million tons, 59% of which sold in the domestic market and 41% in exports and sales by our overseas subsidiaries.

In December 2015, we concluded the merger of Namisa’s assets with CSN’s mining and associated logistics assets, involving the Casa de Pedra, Engenho and Pires mines, and their respective assets, the rights to operate the Tecar port terminal in Itaguaí and the 18.63% interest in MRS, resulting in the current structure of Congonhas Minérios.

In 2015, CSN produced and sold approximately 2.2 million tons of cement from two production units, Volta Redonda (RJ) and Arcos (MG).

CSN is one of the largest industrial electricity consumers in Brazil, holding electricity generation assets through interest in consortiums of hydropower plants. It also generates energy integrated to its production process, thereby ensuring its energy self-sufficiency.

3- OUTLOOK, STRATEGY and INVESTMENTS

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

3.1- STEEL

The Presidente Vargas Steelworks in Volta Redonda is CSN’s most important steel production unit, with an installed crude steel production capacity of 5.9 million tons per year. In addition to its units in Brazil, CSN has three subsidiaries abroad: CSN LLC, in the U.S.A., Lusosider, in Portugal, and SWT, in Germany. In 2016, the main strategies of the steel units include: i) maximizing the use and sale of coated products; ii) the reduction of finished product inventory; and iii) cost reduction and increase in energy efficiency.

3.2- MINING

Congonhas Minérios is Brazil’s second largest iron ore exporter in terms of sales of iron ore finished products. In 2015, it sold approximately 27 million tons of iron ore and allocated 5.5 million tons to the Presidente Vargas Steelworks. In turn, Tecar shipped approximately 28.2 million tons of iron ore in 2015. In 2016, Congonhas Minérios will continue with its ongoing plan to reduce operating costs and capture synergies to face the current iron ore price scenario.

3.3- CEMENT

The Company has continued to invest in expanding its production capacity to 5.4 million tons per year. In 2015, two new crushing facilities were delivered to Arcos (MG), increasing annual capacity by 2.2 million tons of cement. With the implementation of the new clinker kiln in Arcos (MG), scheduled for 2016, CSN will achieve self-sufficiency in the production of this raw material and it is expected to become one of the most competitive players in the regions where it operates.

3.4 – LOGISTICS

Ports

The port of Tecon, managed by Sepetiba Tecon, a subsidary of CSN, is the largest container terminal in Rio de Janeiro and one of the largest in its segment in Brazil. In order to expand the terminal, the Company has been investing in infrastructure, including the acquisition of new equipment, as well as the equalization of Berth 301, transforming it into a continuous quay, and allowing it to handle several large vessels simultaneously, thereby raising capacity to more than 600,000 TEUs¹ per year. The Company continues to expand its commercial lines through new routes with Asia, South America and Central America, consolidating itself as a cargo hub port.

Railways

CSN retains an interest in three rail companies: MRS Logística S.A., Transnordestina Logística S.A. and FTL Ferrovia Transnordestina Logística:

MRS

CSN holds, directly and indirectly, a 34.94% interest in MRS Logística, which operates the former Southeastern Network of the Federal Railways (RFFSA), in the Rio de Janeiro - São Paulo - Belo Horizonte corridor. MRS’ rail services play a vital role in supplying the Presidente Vargas Steelworks with raw materials, such as iron ore, coke and coal. It also transports all the iron ore for export, as well as some of CSN’s steel and cement output.

Transnordestina Logística S.A. (TLSA)

With the support of the federal government, TLSA is building Nova Transnordestina, a 1,753 km railway connecting the rail terminal in Eliseu Martins (PI) to the Ports of Suape (PE) and Pecém (CE), crossing several cities in the states of Piauí, Pernambuco and Ceará. The railway’s projected annual operating capacity of 30 million tons will play a crucial role in the development of the Northeast, providing logistical support for the oil and by-product, agriculture and mining sectors, among others.

FTL - Ferrovia Transnordestina Logística S.A. (FTL)

FTL operates the former Northeastern network of the RFFSA, traversing seven states: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas, with a total extension of 4,534 km and a current operating capacity of around two million tons per year, with emphasis to fuel cargo, cement, and pulp, among others. Currently FTL’s operational railway network connects the states of Maranhão, Piauí and Ceará through its 1,191 kilometers. The traffic on the remaining rail stretches has been suspended. Said stretches are under negotiations to return to the ANTT and DNIT.

4- MAIN CORPORATE EVENTS

Corporate restructuring of indirect subsidiaries

On December 11 2014, CSN’s Board of Directors approved the establishment of a strategic alliance with the Asian Consortium comprising ITOCHU Corporation, JFE Steel Corporation, POSCO, Ltd., Kobe Steel, Ltd., Nisshin Steel Co, Ltd. and China Steel Corp. (“Asian Consortium”). The transaction was concluded on November 30, 2015.

It consisted of the combination, in a new company, Congonhas Minérios S.A., of the mining and associated logistics businesses of the Company and Namisa, including the commercial establishment associated with the Casa de Pedra iron ore mine, the 18.63% interest in MRS and the rights to operate the Tecar port terminal, in Itaguaí (RJ).

The various steps of the transaction are listed below:

¹ TEU – Twenty-foot equivalent unit

• Payment of dividends by Namisa totaling US$1.4 billion, equivalent to R$5.4 billion, which were paid before the closing of the transaction;

• Restructuring of Congonhas with the transfer, by CSN, of CSN’s assets and liabilities related to Casa de Pedra, the rights to operate the Tecar, 60% of the shares of Namisa, 8.63% of the shares of MRS and US$850 million in debt, equivalent to R$3,370 million, as disclosed in note 9 c;

• The acquisition by Congonhas of 40% of Namisa’s shares held by the Asian Consortium, with the merger of said company by Congonhas;

• The signature of Congonhas’ shareholders’ agreement;

• Payment by CSN of US$680 million related to the acquisition of 4% of the shares held by the Asian Consortium in Congonhas and additional US$27 million related to the acquisition of 0.16% of the shares also held by the Asian Consortium in Congonhas, totaling US$707 million, equivalent to R$2.7 billion; and

• Settlement of the pre-existing agreements with Namisa related to the supply of high and low silica ROM, port services and iron ore processing.

Considering the position of Congonhas’ assets, the transfers by the Asian Consortium in the transaction, as well as the adjustments resulting from the negotiations between the parties, and debt, cash and working capital difference adjustments, on conclusion of the transaction, CSN and the Asian Consortium held 87.52% and 12.48% of Congonhas Minérios, respectively.

The transaction also includes an "earn-out" mechanism, which, in the case of a qualified liquidity event that occurs within certain valuation parameters and within an agreed period of time after conclusion of the transaction, could dilute, at CSN's sole discretion, the Asian Consortium’s interest in Congonhas Minérios from 12.48% to up to 8.21%. This mechanism was considered a contingent asset and no associated asset was booked.

Part of Congonhas Minérios’ iron ore production will be sold to members of the Asian Consortium and to CSN. These rights are reflected in long-term supply agreements, entered into on November 30, 2015, whose terms were negotiated adopting commonly used market conditions. The Company also secured the use of TECAR for raw materials imports by entering into a long-term agreement.

Also in 2015, CSN Cimentos was merged by the Company, resulting in an economy of scale due to the reduction of operational and administrative expenses.

In the same year, Companhia Metalúrgica Prada incorporated its subsidiary Rimet Empreendimentos Industriais e Comerciais in order to optimize processes and maximize results.

At the end of 2015, CSN Islands X was extinguished as a result of its merger with CSN Islands VII.

Constitution of subsidiaries1

In 2015, CSN constituted Nordeste Logística for the logistics exploration of the Private Use Terminal on the coast of Ceará state, in the region of influence of Pecém Port Terminal. Nordeste Logística is currently in pre-operating phase.

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.

The year 2015 was marked by the consolidation of the new Performance Evaluation model. Through this practice we evaluate employee adherence to the necessary organizational skills and the performance achieved over the year. Another 2015 highlight was the implementation of the new cycle of the Career and Succession program. Through this practice, we identify and evaluate potential successors, continuously forming new leaders.

Further improving employee development at various levels remains one of our permanent priorities. In 2015, we invested 363,592 thousand hours in training, with the goal of generating knowledge and developing the skills necessary to achieve corporate goals. We held two new development modules of the Leaders’ School, with the participation of around 1300 managers. Through this program, we increase the awareness of leadership responsibilities, concepts and behaviors and prepare and encourage our leaders regarding the proactive positioning when facing challenges.

CSN closed 2015 with around 23,000 employees and a turnover rate of around 14%, one of the lowest in the industrial sector.

8- SOCIAL RESPONSIBILITY

CSN’s social responsibility projects are created to value the potential of each region where it operates and their respective communities, in partnership with the local government and society. In 2015, it invested R$15.7 million in the educational, cultural, sporting and health areas through CSN Foundation initiatives and through projects developed by partner institutions, supported by tax incentives.

The CSN Foundation’s cultural and educational initiatives are present in the “Garoto Cidadão” project, which provides social and cultural activities for 1,900 socially vulnerable children and teenagers in the communities where the company operates. CSN Foundation maintains two technical schools in Volta Redonda and Congonhas, which had 1,331 students in 2015, 677 of whom on scholarships, while the Bela Vista Hotel-School in Volta Redonda offers 176 places per year for courses in hotel management, providing professional qualification in various areas.

Among the initiatives sponsored by CSN, we highlight the Unibes Cultural programming, the Diálogo no Escuro (dialog in the dark) exhibition, the DOC SP, the restoration of Palácio Laranjeiras, in addition to sports training projects of Volta Redonda and Audax clubs. CSN also sponsored projects in the National Cancer Care Support Program and the Health Care Support Program for People with Special Needs (PRONAS and PRONON) and the Senior Citizens’ Fund, as well as the initiatives of the Support Group for Children with Special Needs (AACD) and the Barretos-SP Cancer Hospital.

9- SOCIAL AND ENVIRONMENTAL RESPONSIBILITY

CSN maintains various social, environmental and sustainability management instruments in order to act in a purposeful way and meet the needs of the various stakeholders involved in the communities and businesses where it operates. The Company's sustainability practices have as main objectives the creation of sustainable values and the management of environmental risks; the optimization and efficiency in the use of natural resources and the control of potential impacts;

Most of CSN’s units have received ISO 14001 environmental certification and it maintains an open communication channel through the Linha Verde (Green Line). All its environmental controls are audited for compliance with the Sarbanes-Oxley Act (SOX).

With the threat of water shortages, especially in the Southeast, CSN has been proceeding with various initiatives to ensure the more efficient use of water in its production processes, exemplified by a water reuse ratio of more than 92% at the Presidente Vargas Steelworks (UPV). In 2014, the Company made a water inventory of its units: UPV (RJ), CSN Cimentos (RJ), Namisa and Casa de Pedra (MG); TECAR and TECON (RJ), which allowed it to prepare plans and measures to help the Company improve its efficiency and reduce potential impacts.

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.

CSN confirmed its commitment to sustainable development, committing to the seven sustainability principles of the industry, through the signature of the Sustainable Development Charter of the World Steel Association, which has the adherence of 75 steelmakers around the world.

Finally, CSN has been constantly mapping its stakeholders and, since 2012, it uses mapping criteria to assess environmental, social and economic impacts, in accordance with the Global Reporting Initiative (GRI) guidelines, 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.

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 has shares listed on the São Paulo Stock Exchange (BM&F BOVESPA) and on the New York Stock Exchange (NYSE). Accordingly, the Company reports its information to the Brazilian Securities Commission (CVM) and the U.S. Securities and Exchange Commission (SEC).

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

· Steel:

The Company’s main industrial facility is the Presidente Vargas Steel Mill (“UPV”), located in the city of Volta Redonda, State of Rio de Janeiro. This segment consolidates the 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 operations in the United States, Portugal and Germany, all of them are in line with the plan to achieve new markets and perform excellent services for final consumers. Its steel has been used in home appliances, civil construction and automobile industries.

· Mining:

The production of iron ore is developed in the city of Congonhas, State of Minas Gerais.

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 accomplished by TECAR, a solid bulk terminal, one of the four terminals that compose the Port of Itaguai, located in Rio de Janeiro, which was transferred to the subsidiary CSN Congonhas Minérios S.A. on 31, December 2015. Imports of coal and coke are made through this terminal to the steel industry of CSN.

From November 30, 2015 the Company has transferred its mining assets, which includes the mine Casa de Pedra and the terminal TECAR, to its subsidiary Congonhas Minérios S.A. In the new structure Congonhas Minérios S.A. also stared to control Namisa trough out a business combination transaction, the details are described in note 3.

It further tin mines, based in the State of Rondônia, is engaged to supply the needs of UPV, with the excess of these raw materials being sold to subsidiaries and third parties.

· Cement:

CSN entered in the cement market boosted by the synergy between this new activity and its existing businesses. Next to the Presidente Vargas Steel Mill in Volta Redonda (RJ), it is installed a new business unit: CSN Cimentos, which produces CP-III type of cement by using slag produced by the UPV blast furnaces in Volta Redonda. It also explores limestone and dolomite at the Arcos unit, in the State of Minas Gerais, to satisfy the needs of UPV as of the cement plant.

· Logistics

Railroads:

CSN has equity interests in three railroad companies: MRS Logística S.A., which manages the former Southeast Railway System of Rede Ferroviária Federal S.A., Transnordestina Logística S.A. (“TLSA”) and FTL - Ferrovia Transnordestina Logística S.A. (“FTL”), which operate the Northeast Railway System of RFFSA, in the States of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas, with TLSA being responsible for the sections of Missão Velha-Salgueiro, Salgueiro-Trindade, Trindade-Eliseu Martins, Salgueiro-Porto de Suape and Missão Velha-Porto de Pecém (Railway System II) and FTL being responsible for the sections of São Luiz-Mucuripe, Arrojado-Recife, Itabaiana-Cabedelo, Paula Cavalcante-Macau and Propriá-Jorge Lins (Railway System I).

Ports:

In the State of Rio de Janeiro, by means of its subsidiary Sepetiba Tecon S. A., the Company operates the Container Terminal (Tecon) at the Itaguaí Port. Located in the harbor of Sepetiba, this port has a privileged highway, railroad and maritime access.

Tecon handles the shipments of CSN steel products, movement of containers, as well as storage, consolidation and deconsolidation of cargo.

· Energy:

Since the energy is fundamental in its production process, the Company has assets to generate electric power for guaranteeing its self-sufficiency.

In the preparation of the consolidated financial statements the following consolidation procedures have been applied:

· 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 costs, 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 (including special purpose 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 actually 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 costs, 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.

· 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, in line item “Valuation adjustments to 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. This may mean that amounts previously recognized in other comprehensive income are reclassified to profit or loss.

2.c) Parent company financial statements

In the parent company individual 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, were 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, 2015 related to monetary assets and liabilities denominated in foreign currencies are recognized in the income statement, except when they are recognized in shareholders' equity as a result of monetary items of foreign operation characterized as foreign investment.

The balances of assets and liabilities are translated by exchange rates prevailing at the end of the reporting period. As of December 31, 2015, US$1 is equal to R$3.9048 (R$2.6562 at December 31, 2014) and €1 is equal to R$4.2504 (R$3.2270 at December 31, 2014).

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 finance income or costs.

Changes in the fair value of monetary securities denominated in foreign currency, classified as available-for-sale, are segregated into exchange differences related to the amortized cost of the security and other changes in the carrying amount of the security. Exchange differences related to amortized cost are recognized in profit or loss, and other changes in the carrying amount are recognized in shareholders' equity.

Exchange differences on non-monetary financial assets and liabilities classified as measured at fair value through profit or loss are recognized in profit or loss as part of the gain or loss on the fair value. Exchange differences on investments classified as available-for-sale are included in comprehensive income in shareholders' equity.

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:

· 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.

On consolidation, exchange differences resulting from the translation of monetary items with characteristics of net investment in foreign operations are recognized in shareholders' equity. When a foreign operation is partly disposed of or sold, exchange differences previously recorded into other comprehensive income are recognized in the income statement as part of the gain or loss on sale.

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. Certificates of deposit that can be redeemed at any time without penalties are considered as cash equivalents.

2.f) Trade receivables

Trade receivables are initially recognized at fair value, including the related taxes and expenses. Foreign currency-denominated trade receivables are adjusted at the exchange rate in effect at the end of the reporting period. The allowance for estimated losses on doubtful debts were recognized in an amount considered sufficient to cover any losses. Management’s assessment takes into consideration the customer’s history and financial position, as well as the opinion of our legal counsel regarding the collection of these receivables for recognizing the allowance for estimated 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. 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 and available-for-sale investments 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) Business combination

The acquisition method is used to account for on each business combination conducted by the Company. The payment obligation 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. The Company recognizes non-controlling interests in the acquiree according to the proportional non-controlling interest held in the fair value of the acquiree’s net assets.

2.j) 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 10. 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 of than 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.

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.k) 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.

Mineral rights acquired are classified in line item ‘’other assets’’ in intangible assets.

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

· 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 acquiree´s assets and liabilities. Goodwill on acquisitions of subsidiaries is recognized as intangible assets in the consolidated financial statements. In the parent company statements, goodwill is included in investments. The gain on purchase is recognized as a gain in profit for the period at the acquisition date. Goodwill is annually tested for impairment. 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 Cash-Generating Units or groups of Cash-Generating Units that are expected to benefit from the business combination in which the goodwill arose, and recalling 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 from one to five years.

2.l) 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, are tested for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. An impairment loss is recognized by the exciding value of an asset´s 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, are subsequently reviewed for possible reversal of the impairment at the reporting date.

2.m) Employee benefits

i. 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 flow back to CSN. 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 plan reimbursements or reduction in future contributions to the plan. In calculating the present value of economic benefits, consideration is given to any minimum funding requirements that apply to any Company plan. 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.

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.

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

ii. 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.n) 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, taking into account 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). When some or all of 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.o) Concessions

The Company has governmental concessions to provide the following types of services: railway and port transportation managed by Company´s subsidiaries and joint-ventures. The concessions included in the consolidated financial statements are related to the rail network in the Northeast area, managed by the subsidiary FTL, the container terminal in Itaguaí, managed by the subsidiary TECON and the port terminal TECAR for exporting ore and importing coal, which is managed by the subsidiary Congonhas. The joint venture concessions are not disclosed in these financial statements.

The Company´s concession contracts are not within the scope of the international interpretative standard ICPC01/IFRIC12, considering that the grantor (refers to the government) has effectively no control over what, to whom and at what price the services will be provided by the dealer (refers to the private part) to the customers. In essence, all concession contracts has operating leasing characteristics. Therefore, the accounting should follow the accounting rules applicable to leases. Our concession agreements provide for the use of a specific asset for an agreed period of time, but without any transfer of ownership to the Company or option to buy these assets after the completion of these contracts.

Payments made under operating leases are recognized in the income statement on a straight line basis over the period of the contracts.

2.p) 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 reissued. When these shares are subsequently reissued, 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.q) Revenue recognition

Operating revenue from the sale of goods in the normal course of business is measured at the fair value of the receivables. Revenue is recognized when there is convincing evidence that the most significant risks and rewards of ownership of goods have been transferred to the buyer, it is probable that future economic benefits will flow to the entity, the associated costs and possible return of goods can be reliably estimated, there is no continued involvement with the goods sold, and the amount of the operating revenue can be reliably measured. 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. Revenue from services provided is recognized as it is realized.

The appropriate timing for transfer of risks and rewards varies depending on the individual terms and conditions of the sales contract. For international sales, this timing depends on the type of term of the contract term.

2.r) Finance income and finance costs

Finance income includes interest income from funds invested (except available-for-sale financial assets), dividend income not accounted for under the equity method, gains on disposal of available-for-sale financial assets, 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.

Finance costs comprise interest expenses on borrowings, dividends on preferred shares classified as liabilities, 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.s) 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.

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 in less than 10 years.

2.t) 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.u) 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.

2.v) 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.w) Financial instruments

i) Financial assets

Financial assets are classified into the following categories: measured at fair value through profit or loss, loans and receivables, held-to-maturity, and available-for-sale. The classification depends on the purpose for which the financial assets were acquired. Management determines the classification of its financial assets at the time of initial recognition.

· Financial assets measured at fair value through profit or loss

Financial assets at fair value through profit or loss are financial assets held for active and frequent trading. Derivatives are also categorized as held for trading and, accordingly, are classified in this category unless they have been designed as cash flow hedging instruments. Assets in this category are classified in current assets.

· Loans and receivables

This category includes loans and receivables that are non-derivative financial assets with fixed or determinable payments not quoted in an active market. They are included in current assets, except those with maturity of more than 12 months after the end of the reporting period (which are classified as non-current assets). Loans and receivables include loans to associates, trade receivables, other receivables and cash and cash equivalents, except short-term investments. Cash and cash equivalents are recognized at fair value. Loans and receivables are carried at amortized cost using the effective interest method.

· Held-to-maturity assets

These are basically financial assets acquired with the positive intent and ability to hold to maturity. Held-to-maturity investments are initially recognized at their value plus any directly attributable transaction costs. Subsequent to initial recognition, they are measured at amortized cost using the effective interest method, less any impairment loss.

· Available-for-sale financial assets

These are non-derivative financial assets, designated as available-for-sale, that are not classified in any other category. They are included in non-current assets when they are strategic investments for the Company, unless Management intends to dispose of the investment within 12 months from the end of the reporting period. Available-for-sale financial assets are recognized at fair value.

· Recognition and measurement

Regular purchases and sales of financial assets are recognized at the trading date - the date on which the Company undertakes to buy or sell the asset. Investments are initially recognized at their fair value, plus transaction costs for all financial assets not classified as at fair value through profit or loss. Financial assets at fair value through profit or loss are initially recognized at their fair value and the transaction costs are charged to the income statement. 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. Available-for-sale financial assets and financial assets measured at fair value through profit or loss are subsequently carried at fair value. Loans and receivables are carried at amortized cost using the effective interest method.

Gains or losses resulting from changes in the fair value of financial assets measured at fair value through profit or loss are presented in the income statement under “finance income” in the period in which they arise. Dividend income from financial assets at fair value through profit or loss is recognized in the income statement as part of other finance income when the Company’s right to receive the dividends has been established.

The changes in the fair value of available-for-sale financial assets are recognized as follows: (i) the effects of foreign exchange differences and the changes in the fair value of the investment in the investee’s capital are recognized directly in the Company’s shareholders’ equity, in “Other comprehensive income” and; (ii) the effects of foreign exchange differences and the changes in the option’s fair value are recognized in the income statement for the year.

Interest on available-for-sale securities, calculated under the effective interest method, is recognized in the income statement as part of other income. Dividends from available-for-sale equity instruments, such as shares, are recognized in the income statement as part of other finance income when the Company’s right to receive payments has been established.

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.

ii) Impairment of financial assets

The Company evaluates in the end of each reporting period whether there is an evidence that a financial asset or a group of financial assets are impaired.

· Assets measured at amortized cost

A financial asset or a group of financial assets is impaired and impairment losses are incurred only if there are evidences of impairment as a result of one or more events that occurred after the initial recognition of the asset (a “loss event”),such loss event (or events) has an impact on the estimated future cash flows of the financial asset or group of financial assets and the future cash flow estimation can be reliably calculated..

The criteria used by CSN to determine whether there are evidences of impairment loss includes:

· significant financial weakness related to the issuer or counterparty;

· a breach of contract, such as default or delinquency at interest or principal payments;

· the issuer, for economic or legal reasons relating to the borrower’s financial weakness, grants to the borrower a concession that the lender would not otherwise consider;

· it becomes probable that the borrower will incur in bankruptcy or other financial reorganization;

· the disappearance of an active market for the related financial asset because of financial weakness; or

· observable data indicating that there is a measurable decrease in the estimated future cash flows from a portfolio of financial assets since the initial recognition of such assets, although the decrease cannot yet be identified with the individual financial assets in the portfolio, including:

- Adverse changes in the payment status of borrowers in the portfolio;

- National or local economic conditions that correlate with defaults on the assets in the portfolio.

The amount of the loss is measured by the difference between the carrying amount of the asset and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the original effective interest rate of the financial asset. The carrying amount of the asset is reduced and the amount of the loss is recognized in the income statement. If a loan or held-to-maturity investment has a variable interest rate, the discount rate to measure an impairment loss is the current effective interest rate determined pursuant to the contract. As a practical expedient, the Company may measure impairment on the basis of an instrument’s fair value using an observable market price.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized (such as an improvement in the debtor’s credit rating), the previously recognized impairment loss is reversed and recognized in the consolidated income statement.

· Assets classified as available-for-sale

In the case of equity securities classified as available-for-sale, a significant or prolonged decline at the fair value of an investment in an equity instrument below of its cost is also an evidence of impairment. Determining what is considered a “significant” or “prolonged” decline requires judgment. For this judgment we assess, among other factors, the historical changes in the equity prices, the duration and proportion in which the fair value of the investment is lower than its cost as well as the financial health and short-term business prospects for the investee, including factors such as: industry and segment performance, changes in technology and operating/financial cash flows. If any of the impairment evidences is observed for available-for-sale financial assets, the cumulative loss—measured as the difference between the acquisition cost and the current fair value, less any impairment loss on the financial asset previously recorded in profit or loss—is reclassified from equity to profit or loss. Impairment losses recognized in the income statement as available-for-sale instruments are not reversed.

CSN tested for impairment its available-for-sale investment in Usiminas shares, see note 13 – Financial Instruments.

iii) Financial liabilities

Financial liabilities are classified categories ‘’measured at fair value through profit or loss’’ and ‘’other financial liabilities’’. Management determines the classification of its financial liabilities at the time of initial recognition.

· Financial liabilities measured at fair value through profit or loss

Financial liabilities measured at fair value through profit or loss are financial liabilities held for trading or designated as at fair value through profit or loss.

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

· Other financial liabilities

Other financial liabilities are measured at amortized cost using the effective interest method.

The Company holds the following non-derivative financial liabilities: borrowings, financing and debentures, as well as trade payables.

· 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 “Finance income (costs)” in the income statement.

· Cash flow Hedge activities

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 profit or loss.

The amounts accumulated in equity are realized at the income statement in the periods when the forecast exports affect profit or loss.

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. When the forecast transaction is completed, the gain or loss is reclassified to profit or loss. 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 “Finance income (costs)”.

The movements in the hedge amounts designated as exporting cash flow hedges are stated in note 13.

· Net investment hedge activities

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 maturity of the financial liabilities is related to the exchange variation of 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 out various 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 finance income (costs), 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 a finance income/cost (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 13.

2.x) 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.y) Government grants

Government grants are not recognized until there is reasonable assurance that the Company will comply to the conditions attaching to them and assurance that the grants will be received, so then they will be recognized in profit or loss on a systematic basis over the periods in which the Company recognizes as expenses the related costs that the grants are intended to compensate.

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

2.z) New standards and interpretations issued and not yet adopted

The following standards, amendments to standards and IFRS interpretations issued by the IASB are not yet effective and were not early adopted by the Group for the year ended December 31, 2015:

Standard

Description

Effective date

IAS 16 and IAS 38

Property, Plant and Equipment and Intangible Assets – in May 2014 these accounting standards were revised to clarify that the revenue method will no longer be permitted for depreciation or amortization purposes.

2016

IFRS 10 and IAS 28

Consolidated Financial Statements and Investments in Associates and Joint Ventures – in September 2014 a revision was issued proposing that the gain or loss resulting from the sale or contribution of a subsidiary that does not constitute a business as defined in IFRS 3 to an investor’s subsidiary or joint venture should only be recognized to the extent of the unrelated investors' interests in the subsidiary or joint venture.

2016

IFRS 7

Financial Instruments: Disclosures – in September 2014 the IASB revised IFRS 7 to provide guidance to clarify whether a servicing contract is continuing involvement and that the additional disclosure requirements are not specific for interim reporting periods. This change has not yet been ratified by the CPC and should be adopted from 2016, with earlier application permitted.

2016

IFRS 9

Financial Instruments. IFRS 9 retains, but simplifies, the combined measurement model and establishes two main measurement categories of financial assets: amortized cost and fair value. The classification basis depends on the entity’s business model and the characteristics of the financial asset's contractual cash flow.

IFRS 9 retains most of IAS 39 requirements for financial liabilities.

The main change refers to those cases where the fair value of the financial liabilities must be segregated so that the fair value portion related to the entity’s credit risk is recognized in “Other comprehensive income” and not in profit or loss for the period.

The guidance on IAS 39 on the impairment of financial assets and hedge accounting is still applicable.

2018

IFRS 11

The amendments to IFRS 11 provide guidance on how to account for the acquisition of a joint operation that constitutes a business as defined in IFRS 3 for a business combination. The amendments also make it clear that the equity interest previously held in a joint operation is not re-measured on the acquisition of an additional equity interest in the same joint operation for as long as joint control is retained.

2016

IFRS15

Revenue from Contracts with Customers. This new standard introduces the principles that an entity will apply to determine the revenue measurement and when such revenue shall be recognized.

IFRS15 replaces IAS 11 Construction Contracts, IAS 18 Revenue, and related interpretations.

2018

IFRS16

Defines the principles for recognition, measurement,

presentation and disclosure of leases. IFRS 16 replaces IAS17 - Leases and related interpretations.

2019

There are no other standards, amendments to standards and interpretations not yet effective that the Group expects to have a material impact on its financial statements.

· Forfaiting

Trough out the financial years 2014 and 2015 the Company purchased raw materials from its suppliers located abroad through a foreign trade operation called Forfaiting, in which the financial institution makes the payment in cash to exporter by the net values of the securities (discount rate and other possible expenses already deducted), allowing the Company to finance imported goods by an yearly interest rate from 1.25% to 3.28%, maturing in 12 months. As of 31 December, 2015, this liability amounted to R$ 288,772 in consolidated and parent company (R$ 414,442 at December 31, 2014, in consolidated and parent company).

· Drawee risk

During the financial years 2014 and 2015 the Company carried out transactions denominated drawee risk, the transaction occurs when the financial institution engaged by the Company anticipates to suppliers the debt securities, so then subsequently receives from the Company on the maturity date those anticipated values. As of 31 December, 2015, this liability amounted to R$84,063 in consolidated and parent company (R$56,237 at December 31, 2014, in consolidated and parent company).

3. BUSINESS COMBINATION - Acquisition of control of Nacional Minérios S.A. (Namisa)

3.1 Object of transaction

On December 11, 2014, the Board of Directors of CSN approved the establishment of a strategic alliance with an Asian Consortium comprised by the companies ITOCHU Corporation, JFE Steel Corporation, POSCO, Ltd., Kobe Steel Ltd., Nisshin Steel Co, Ltd. and China Steel Corp. (“Asian Consortium”).

The transaction consisted of a business combination through which the Asian Consortium contributed its equity interest of Namisa (40%) into Congonhas Minérios S.A. (“Congonhas Minérios”), a mining subsidiary of CSN. After the corporate restructuring, Congonhas Minérios became the holder of the commercial establishment related to CSN’s iron ore mine Casa de Pedra, CSN’s equity interest of Namisa (60%), 8,63% direct interest in MRS, as well as the right to manage and operate the solid bulk terminal of TECAR in Itaguaí Port (“TECAR”).

The transaction was concluded by the signing of a shareholders agreement by the shareholders of Congonhas Minérios, on November 30, 2015.

The following steps were carried out in order to conclude the transaction:

· Payment of dividends by Namisa before closing of the transaction, amounting to US$1.4 billion (equivalent to R$5.4 billion);

· Restructuring of Congonhas Minérios through the contribution, by CSN, of the assets and liabilities related to Casa de Pedra, the rights to operate TECAR, 60% of Namisa’s shares, 8.63% of MRS’ shares, and US$850 million in debt (equivalent to R$3,370 million, as presented in note 9.c);

· Acquisition, by Congonhas Minérios, of 40% of the Namisa shares held by the Asian Consortium, resulting in the incorporation of Namisa by Congonhas Minérios;

· Signing of a shareholders agreement (“Shareholders’ Agreement”) by the shareholders of Congonhas Minérios;

· Payment by CSN of US$680 million relating to the acquisition of 4% of the shares held by the Asian Consortium in Congonhas Minérios and additional US$ 27 million relating to the acquisition of 0.16% of the shares held by the Asian Consortium in Congonhas Minérios, amounting to US$ 707 million (equivalent to R$2.7 billion);

· Settlement of the pre-existing agreements with Namisa for supply of high-silicon and low-silicon content ROM (Run of Mine), port services and ore beneficiation.

The following organization chart shows the new corporate structure after the transaction:

Considering the position of Congonhas Minérios’ assets, the contributions made by the Asian Consortium in the transaction, as well as adjustments resulting from the negotiations between the parties and adjustments of debt, cash and working capital, CSN and the Asian Consortium held, respectively, equity stakes of 87.52% and 12.48% in the capital stock of Congonhas Minérios upon conclusion of the transaction.

The transaction also includes an earn-out mechanism by which, in the event of a qualified liquidity event occurred under certain valuation parameters and within a defined time period after the closing of the transaction, the Asian Consortium’s equity interest in Congonhas Minérios could be diluted, at CSN´s sole discretion, from 12.48% to 8.21%. This mechanism was considered as a contingent asset and no related value was accounted thereto.

Part of the iron ore produced by Congonhas Minérios will be sold to the members of the Asian Consortium and to CSN. Such rights are reflected in long-term supply agreements entered into on November 30, 2015, which terms were negotiated on usual market conditions. CSN also ensured the use of TECAR for import of raw materials through a long-term agreement.

3.2 Application of CPC15/IFRS3 to the transaction

Prior to the transaction, Namisa was managed by means of a shareholders agreement, through which the Asian Consortium had sufficient vetoes that grant it substantial management rights over the operations. With respect to accounting, Namisa was classified as a joint venture within the scope of IFRS 10 and 11. CSN recorded its 60% equity interest in Namisa according to the equity method.

As mentioned above, CSN carried out a corporate restructuring involving the transfer of its mining operations, rights to operate the port terminal TECAR and equity interests in Namisa and MRS to Congonhas Minérios. This step of the transaction was carried out based on the book value of the assets, since there was no change control over the assets and equity stakes transferred. Upon conclusion of the corporate restructuring, Congonhas Minérios became the controlled company of CSN that concentrates the group’s mining businesses.

As a result of the transaction, Namisa became fully controlled by Congonhas Minérios. The Asian Consortium holds only protective vetoes in relation to the assets resulting from the business combination, usual in this type of transaction.

Accordingly, since there has been alteration of control over Namisa’s assets, CPC15/IFRS3 should be applied. Under the parameters of such accounting standards, the acquisition date for purposes of accounting records was November 30, 2015 and the acquirer considered for transaction purposes was Congonhas Minérios. Namisa was the acquiree.

3.3 Application of the acquisition method

Under CPC15/IFRS3, the acquisition method shall be applied for recording the transaction. The method consists of the following:

a) determining the purchase price;

b) recognizing the amount of the goodwill based on expectations for future profitability; and

c) recognizing a gain or loss on pre-existing relations that should be settled with the business combination.

These three steps are applicable to the acquisition of control over Namisa, and they are detailed as follows.

a) Determination of the purchase price

According to CPC15/IFRS3, the purchase price is determined by the sum of the transferred assets, liabilities incurred, equity interests issued, non-controlling equity interests and the fair value of any equity interest held prior to the transaction. The following table summarizes the price considered for accounting purposes:

Item	Comment	R$ million	Ref.
Assets transferred	A payment in the amount of USD707MM is being carried out in the transaction.	2,727	(i)
Liabilities assumed	Refers to financial adjustment of working capital and debt.	6	(i)
Equity interests issued	Congonhas Minérios issued shares that were delivered to the Asian Consortium.	2,619	(ii)
Fair value of the equity interest held by the acquiring company in the company acquired immediately prior to the combination	Congonhas Minérios held 60% of the Namisa shares prior to the business combination and appraised such equity interest at fair value.	8,023	(iii)
Purchase price considered for the business combination		13,375

i. Assets transferred and liabilities assumed

Subsequent to the capital increase, the transaction included a payment made for acquisition of 4.16% of Congonhas Minérios’ shares held by the Asian Consortium in the amount of US$707 million, equivalent to R$2,727 as of November 30, 2015 and a liability amounting to R$6 to be paid along 2016.

Even though such payment was carried out by CSN for the acquisition of Congonhas Minérios shares, its economic effect was recorded at Congonhas Minérios as an integral part of the consideration received due to the control acquisition over Namisa, according to the guidelines provided by CPC15/IFRS3.

ii. Equity interests issued – Shares in capital stock of Congonhas Minérios

Congonhas Minérios performed the primary issue of shares to the Asian Consortium representing 12.48% of its total capital. Pursuant to CPC15/IFRS3, such shares were appraised at fair value as of the acquisition date.

Such appraisal was performed using the discounted cash flow method, considering the business plans approved by the shareholders of Congonhas Minérios. The main premises of such appraisal and the results thereof are described in the table below:

Premises		Figures
Volumes of iron ore		60Mt/year over the long-term
Prices - Platts CFR China 62% Fe		Intervals from US$56 to US$75
Discount rate		Nominal WACC of 13.91%
Fair value as of Nov. 30, 2015 (equity value)		R$20,988 million
Percentage of shares held by the Asian Consortium after acquisition of the 4.16% equity interest		12.48%
Fair value attributed to the shares issued		R$2,619 million

The fair value of Congonhas Minérios was calculated by independent appraisers who issued an appraisal report.

iii. 60% equity interest in Namisa held prior to the acquisition

Congonhas Minérios held 60% of Namisa’s shares immediately prior to the transaction regarding the acquisition of control be concluded. Such shares were appraised under the equity method.

According to item 41 of CPC15/IFRS3, such shares are part of the consideration transferred and should be measured at their fair value as of the acquisition date. A gain or loss resulting from the difference between the fair value and the carrying amount recorded immediately prior to the acquisition should be recognized in profit or loss for the year.

The appraisal of the fair value of Namisa was conducted according to the discounted cash flow method, considering the business plans in effect prior to the transaction and approved by the shareholders. The main premises of such appraisal and the results thereof are shown in the following table:

Premises		Figures
Volumes of iron ore		40Mt/year over the long term
Prices - Platts CFR China 62% Fe		Intervals from US$56 to US$75
Discount rate		Nominal WACC of 14.36%
Fair value as of Nov. 30, 2015 (equity value)		R$13,375 million
Fair value attributed to the 60% participation (a)		R$8,023 million
Accounting Balances
Accounting balances considering the elimination of 60% due to the gain in the pre-existing relationship (b)
Carrying value as of Nov. 30, 2015 (60%)		R$6,164 million
Elimination of 60% on the gain of a pre-existing relationship ⁽¹⁾		R$933 million
		5,231 million
Gain on appraisal of the 60% stake at fair value (a–(b)		R$2,792 million

(1) According to item b(i) below, Namisa assets related to pre-existing contracts were adjusted to fair value at the acquisition date. The presentation of the gain in the valuation of the initial participation at fair value considers the elimination of 60% of the gain on the settlement of pre-existing relationship.

The fair value of Congonhas Minérios was calculated by independent appraisers who issued an appraisal report.

b) Goodwill on acquisition of control over Namisa

According to CPC15/IFRS3, the acquirer shall recognize goodwill based on expectations for future profitability as of the acquisition date, measured by the amount at which the purchase price exceeds the fair value of the assets and liabilities acquired (Purchase Price Allocation – PPA). The transaction generated goodwill of R$3,691 million, as per the table below:

Item	R$ million	Ref.
Purchase price considered	13,375	Item (a)
Fair value of the assets and liabilities acquired	9,684	(i)
Goodwill based on expectations for future profitability (Note 11)	3,691

The goodwill based on expectations for future profitability is recorded under Intangible Assets and, since it does not have a definite useful life, it is not amortized, according to CPC 04. As from 2016, CSN will begin conducting impairment testing for this asset according to the requirements established by CPC 01.

(i) Fair value of the assets and liabilities acquired

The following table shows the fair value allocation breakdown for 100% of the assets acquired and liabilities assumed as of November 30, 2015, calculated on the basis of reports prepared by independent appraisers:

				Consolidated

Total equity acquired	10,274,895	(208,721)	(381,831)	9,684,343

According to CPC15/IFRS3, the goodwill based on expectations for future profitability existing in the Namisa's financial statements, as of the acquisition date, should be written off so that a new goodwill is recognized.

The allocation of the fair value resulted in a loss in the total amount of R$208,721, distributed among the principal assets of Namisa. The following table shows the breakdown of the amounts allocated and a summary of the calculation methodology:

Assets acquired	Valuation method	Carrying amounts	Fair value adjustment	Total fair value
Assets acquired	Valuation method	Carrying amounts	Fair value adjustment	Total fair value
Stake in MRS - 10%	Entity's discounted cash flow considering the long-term business plan approved by shareholders.	306,190	480,610	786,800
Agreement for sale of ROM, provision of port services and ore processing between Namisa and Congonhas	The contractual prices were compared with the market prices for ore and port services observed in comparable market purchase and sale transactions, adjusted by fluctuations in Plats projected over the agreement term. Based on the contractual volume, the difference between the result projected on the terms of the agreement and the market conditions generates goodwill.	9,424,748	(1,554,121)	7,870,627
Property, plant and equipment	The amounts of property, plant and equipment were adjusted by the difference between the fair value of the PP&E and their respective net carrying amounts, as per the technical valuation conducted by an independent appraiser for the groups of assets represented by improvements, constructions, vehicles, furniture and fixtures. The useful lives follow the periods disclosed in Note 10.	550,825	156,271	707,096
Mining rights (Mina do Engenho, Fernandinho, Cayman)	The income approach was used based on the excess profitability methodology in multiple periods, due to the possibility of attributing the directly generated cash flow to the asset identified. Under this methodology, the amount of the mining rights is estimated based on their future profitability, discounting all costs and investments that would be necessary for extracting and processing the iron ore to their fair value. These rights will be amortized according to the depletion of the mines.		726,390	726,390
relationship with supplier - contract purchase of iron ore - Itaminas	For the fair value calculation of the contract with Itaminas we used the income approach, comparing the future cash flows generated by operation in two scenarios, through the contract and market conditions.		1,531	1,531
Deferred income tax and social contribution on adjustments			(19,402)	(19,402)
Total		10,281,763	(208,721)	10,073,042

c) Settlement of pre-existing relationships between Congonhas Minérios and Namisa

The CPC15/IFRS3 determines that the increase or decrease in fair value, resulting from an advantage or disadvantage in the transaction between the acquirer and the acquiree, should be eliminated, with recognition of a gain or loss in the income statement of the year as of the transaction date. Such assets or relationships are referred as pre-existing relationship in the context of CPC15/IFRS3.

Congonhas Minérios and Namisa have a pre-existing relationship resulting from long-term agreements for the performance of port services, supply of ROM iron ore and processing of ore. With the business combination, such agreements were extinct, since CSN’s mining activities have now been centralized at Congonhas Minérios.

According to CPC15/IFRS3, due to the fact that the business combination between Congonhas Minérios and Namisa have settled the pre-existing agreements, Congonhas Minérios recognized a gain for the year, recorded in the profit/loss item of Other operating income and expenses, amounting to R$621,648, which is related to the participation of 40% held by the Asian Consortium in the preexisting contracts.

3.4 Effects reflected in CSN parent company - Transaction between partners recorded in equity

As mentioned above, Congonhas Minérios was considered the acquirer for the application of CPC15/IFRS3. As a result to the completion of the transaction, there was a change in CSN’s shareholding in Congonhas Minérios, which has not represented a loss of control in Congonhas Minérios by CSN. The Company’s participation decreased from 100% to 87.52%. According to CPC36/IFRS10, this change should be classified as an equity transaction and the resulting gain or loss on the new value of the equity interest must be recorded directly in equity. Because of this percentage change, it was recorded a gain of R$1,945 million. The following table shows the reconciliation of this amount:

Events		R$ Million
Contribution to the capital of Congonhas Minérios by the Consortium - item (a)		2,619
CSN Participation - 87,52% (1)		2,292
Acquisition by CSN of 4.16% - item (a)		2,727
Consortium participation - 12.48% (2)		(340)

· 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, 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:

(**) Goodwill of flat steel is allocated to the steel operation CSN, considering the operation of the Presidente Vargas Steelworks and other assets involved in other product processing steps until its sale to the customer.

(***) 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.

(****) Refers to the goodwill based on expectations for future profitability, resulting from the acquisition of Namisa by Congonhas Minério, an operation that was concluded in December 2015. As from 2016, the balance will be tested annually for impairment. See further details relating to calculation of the goodwill in note 3 – Business Combination.

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. 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: revenue growth rate, costs and expenses, discount rate, working capital, future Capex investment and macroeconomic assumptions observable in the market.

The main assumptions used in the test were as follows:

Segment	Real Discount Rate	Revenue Growth Rate
Long steel (*)	7.90%	3.53%
Metal packaging	9.39%	6.07%

(*) The assets tested are located in Germany. The discount rate is calculated in Euro and the growth rate is the expectation for the region of Europe, the market in which this CGU generates cash flows.

Based on the analyses conducted by Management, was not necessary to record losses by impairment to those assets in the year ended on December 31, 2015.

13. FINANCIAL INSTRUMENTS

I - Identification and measurement of financial instruments

The Company enters into transactions involving 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 enters into derivative transactions, especially exchange and interest rate swaps.

Considering the nature of these instruments, their fair value is basically determined by using Brazil’s money market and mercantile and futures exchange quotations. The amounts recognized in current assets and current liabilities have immediate liquidity or short-term maturity, mostly less than three months. Considering the maturities and characteristics of such instruments, their carrying amounts approximate their fair values.

Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities.

Level 2 - Includes observable inputs in market such as interest rates, exchange etc., but not prices traded in active markets.

There are no assets and liabilities classified as level 3.

II – Investments in financial instruments classified as available-for-sale and measured at fair value through OCI

Consist mainly of investments in shares acquired in Brazil involving companies considered as top ranked by the Company, which are recognized in noncurrent assets, and any gains or losses are recognized in shareholders' equity, where they will remain until actual realization of the securities or when any loss is considered unrecoverable.

Potential impairment of available-for-sale financial assets

The Company has investments in common (USIM3) and preferred (USIM5) shares of Usiminas (“Usiminas Shares”), designated as available-for-sale financial assets. The Company adopts this designation because the nature of the investment is not comprised in any other categories of financial instruments (loans and receivables, held-to-maturity investments or financial assets at fair value through profit or loss). The asset is classified as a non-current asset in line item “investments” and is carried at fair value based on the quoted price on the stock exchange (BM&FBOVESPA). According to the Company's policy, the gains and losses arising from changes in the price of shares are recorded directly in equity, as other comprehensive income.

The Company's accounting policy requires a quarterly analysis based on quantitative and qualitative information available in the market from the moment the instrument demonstrates a drop of more than 20% of their market value or from a significant drop in market value compared to their acquisition cost for more than 12 months. If the Company concludes that there was a significant drop in the price of the instrument, an impairment loss must be recognized. In 2012, considering the price of Usiminas shares on the BM&FBovespa, was recorded the first impairment loss on that shares. According to this policy, whenever the share price reached a level lower than the last record impairment, the Company should record further losses, redefining the new minimum threshold value of the shares.

In the year 2015 there was a reduction in the price of the shares to the level of the last recorded loss, therefore, the Company recorded the new losses to the income statement in the amount of R$555,298, in line item other operating expenses and constituted the total of R$33,269 as deferred taxes.

The market value of the shares was lower than the base price of the last impairment, as follows:

Class of shares	Quantity	Stock Exchange Market price(BM&FBovespa)
Class of shares	Quantity	Share Market Price of last impairment recorded in 2014	03/31/2015	06/30/2015	09/30/2015	12/31/2015

Preferred	105,215,700	5.05	4.97	4.12	3.35	1.55
	176,606,000

The change in the carrying amount of Usiminas is presented below:

Class of shares	Quantity	12/31/2014		12/31/2015		Market Variation as 2015
Class of shares	Quantity	Share price	Closing Balance	Share price	Closing Balance	Share price	Closing Balance
Common	71,390,300	12.30	878,101	4.02	286,989	(8.28)	(591,112)
Preferred	105,215,700	5.05	531,339	1.55	163,084	(3.50)	(368,255)
	176,606,000		1,409,440		450,073		(959,367)

· Share market price risks

The Company is exposed to the risk of changes in share prices due to the investments made and classified as available-for-sale.

According to the Company’s accounting policies, any negative changes in the investment in Usiminas considered significant (impairment) are recognized in profit or loss, and positive changes are recognized in comprehensive income until the investment is realized.

As of December 2015, the amount recognized in comprehensive income for investments available for sale, net of taxes is R$(73).

III - Financial risk management

The Company has and follows a policy of managing its risks, with guidelines regarding the risks incurred by the company. Pursuant to this policy, the nature and general position of financial risks are regularly monitored and managed in order to assess the results and the financial impact on cash flow. The credit limits and the quality of counterparties’ hedging instruments are also periodically reviewed.

Under this policy, market risks are hedged when it is considered necessary to support the corporate strategy or when it is necessary to maintain a level of financial flexibility.

Under the terms of the risk management policy, the Company manages some risks by using derivative instruments. The Company’s risk policy prohibits any speculative deals or short sales.

13.a) Foreign exchange and interest rate risks

· Exchange rate risk

The exposure arises from the existence of assets and liabilities generated in US dollars or Euro and is denominated natural currency exposure. Net exposure is the result of offsetting the natural currency exposure by hedging instruments adopted by CSN.

The consolidated net exposure as of December 31, 2015 is as follows:

		12/31/2015
Foreign Exchange Exposure	(Amounts in US$’000)	(Amounts in €’000)
Cash and cash equivalents overseas	1,625,202	5,197

Cash flow hedge accounting	1,557,667
Net Investment hedge accounting		120,000
Net foreign exchange exposure	172,822	(66,098)

· Interest rate risk

Risk arises from short and long term liabilities with fixed or post fixed interest rates and inflation rates.

Item 13 b) shows the derivatives and hedging strategies to protect exchange and interest rates risks.

13.b) Hedging instruments: derivatives and hedge accounting

CSN uses several instruments for protection of foreign currency risk and interest rate risk, as shown in the following topics:

Forward exchange rate contracts

As part of the hedging strategy of natural exposure to dollar, CSN contracts foreign exchange derivative instruments. As of December 31, 2015 the Company held in its portfolio forward dollar contracts traded at BM&F Bovespa which totaled the notional amount of US$ 1.435 billion.

These contracts consist in negotiating the exchange rate of Reais to US dollar, for prompt delivery, contracted under Resolution 1.690/90 of the National Monetary Council (CMN) in standard contracts established by BM&F Bovespa. CSN determines the required volume of currency to be purchased in accordance with its foreign exchange management strategy and negotiates a sufficient volume of contracts to achieve this financial volume.

The maturity of the portfolio always occurs on the first business day of the contract´s maturity month, being renewable every 30 days, in average. The contract settlement is exclusively financial, on the due date and occurs daily until the maturity. The position held by the Company is set at the end of each session based on the difference of the day's settlement price (D0) compared to the previous day price (D-1), and is settled on the following day (D+1), according to the rules of BM&F.

For as much as the Company maintains contracts traded on the BM&F Bovespa, it is required by the clearing house a guarantee margin to cover those commitments in these contracts, which is only a percentage of the contract´s total amount. CSN maintains securities linked to this guarantee margin, consisting mainly of government bonds, which will be redeemed after the end position. The amounts of these investments are described in Note 5.

The contracts on the BM&F Bovespa have been carried out to replace the foreign exchange swap contracts (NDF - Non Deliverable Forward) traded in over the counter markets.

Dollar x Euro swap

The subsidiary Lusosider has derivative transactions to protect its dollar exposure versus euro.

Fixed rate-to-CDI swap

The purpose of this transaction is to peg obligations subject to a fixed rate to interest rates based on the average rate of interbank deposits of one day (CDI), calculated and disclosed by CETIP. Basically, the Company contracted swaps for its obligations indexed to fixed rates, in which it receives interest on the notional amount (long position) and pays a 100% of the certificate of deposit interbank - CDI (pre-fixed rate) on the notional amount of the contract date (short position). The gains and losses on this contract are directly related to CDI fluctuations. In general, these are transactions conducted in the Brazilian over-the-counter market that have as counterparty a prime financial institution.

CDI-to-Fixed rate swap

The purpose of this transaction is to peg obligations subject to a post-fixed rate (CDI) to a fixed rate. Basically, the Company contracted swaps for its obligations indexed to CDI, in which it receives interest on the notional amount (long position) and pays a pre-fixed rate on the notional amount of the contract date (short position). The gains and losses on this contract are directly related to CDI fluctuations. In general, these are transactions conducted in the Brazilian over-the-counter market that have as counterparty a prime financial institution.

· Hedge accounting – cash flow

Beginning November 1, 2014, the Company formally designated cash flow hedging relationships to protect highly probable future cash flows against US dollar fluctuations.

In order to better reflect the accounting impacts of this foreign exchange hedging strategy on its profit, CSN designated part of its US dollar-denominated liabilities as a hedging instrument of its future exports. As a result, foreign exchange differences arising on translating the designated liabilities will be temporarily recognized in shareholders’ equity and allocated to profit or loss when such exports are carried out, which will allow recognizing the US dollar impact on liabilities and exports concurrently. Note that adopting hedge accounting does not entail contracting any financial instrument. As of December 31, 2015 the Company designated for hedge accounting US$1,558 million in exports to be carried out between October, 2016 and October, 2022.

To support these designated amounts, the Company prepared formal documentation indicating how hedging is aligned with the goal and strategy of CSN’s Risk Management Policy by identifying the hedging instruments used, the hedging purpose, the nature of the hedged risk, and showing the expected high effectiveness of the designated relationships. The designated debt instruments total an amount equivalent to the portion of future exports. Thus, the exchange differences on translating the instrument and the hedged item are similar. According to the Company’s accounting policy, continuous assessments of the prospective and retrospective effectiveness must be carried out by comparing the designated amounts with the expected amounts, approved in Management’s budgets, and the actual export amounts.

Through hedge accounting, the exchange gains and losses of the debt instruments do 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, 2015:

(1) During the third quarter 2015, we reviewed the future export projections and identified that the amount of US$ 9 million designated previously were not highly probable. According to internal policy, the hedge relationship was discontinued prospectively, since the resume of exports in future periods is possible.

(2) On October, 2015 was settled the portion of debt designated as a hedge instrument. Therefore, we revert to the profit/loss the accumulated exchange rate variation related this installment.

In the hedging relationships described above, the amounts of the debt instruments were fully designated for equivalent iron ore export portions.

The movements in the hedge accounting amounts recognized in shareholders’ equity as of December 31, 2015 are as follows:

	12/31/2014	Addition	Reversal	12/31/2015
Cash flow hedge accounting	120,633	1,410,896	(11,439)	1,520,090

Fair value of cash flow hedge, net of taxes	79,618	1,289,142	(7,550)	1,361,210

As of December 31, 2015 the hedging relationships established by the Company were effective, according to the prospective tests conducted. Thus, no reversal for hedge accounting ineffectiveness was recognized.

· Hedge of net investment in foreign subsidiaries

CSN has natural foreign exchange exposure in euros arising significantly from loan made by a subsidiary abroad with functional currency in Reais, for the acquisition of investments abroad whose functional currency is Euro. Such exposure arises from converting the balance sheets of these subsidiaries for consolidation in CSN, and the exchange rate of the loans affected the income statement in the financial result item and exchange variation of the net assets of the foreign operation directly affected the equity in other comprehensive income.

As from 1 September 2015 CSN began to adopt hedge of net investment to eliminate exposure in order to cover future fluctuations of the euro on such loans. Non-derivative financial liabilities have been designated represented by loan agreements with financial institutions in the amount of € 120 million. The carrying amounts as of December 31, 2015 are:

13.d) Liquidity risk

It is the risk that the Company may not have sufficient net funds to honor its financial commitments as a result of mismatching of terms or volumes between scheduled receipts and payments.

To manage cash liquidity in domestic and foreign currency, assumptions of future disbursements and receipts are established and daily monitored by the treasury area. The payment schedules for the long-term portions of borrowings, financing and debentures are shown in note 12.

The following table shows the contractual maturities of financial liabilities, including accrued interest.

At December 31, 2015	Less than one year	From one to two years	From two to five years	Over five years	Total
Borrowings, financing and debentures	1,901,384	7,238,130	18,674,574	6,571,872	34,385,960

· Fair values of assets and liabilities as compared to their carrying amounts

Financial assets and liabilities at fair value through profit or loss are recognized in current and non-current assets and liabilities, and any gains and losses are recognized as finance income or finance costs, respectively.

The amounts are recognized in the financial statements at their carrying amounts, which are substantially similar to those that would be obtained if they were traded in the market. The fair values of other long-term assets and liabilities do not differ significantly from their carrying amounts, except the amounts below.

The estimated fair values for certain consolidated long-term borrowings and financing were calculated at prevailing market rates, taking into consideration the nature, terms and risks similar to those of the recorded contracts, as compared below:

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

(**) Reversal of Company´s tax credits and tax loss carryforwards to settle tax debts, as provided for in Law N^o. 12,865/13, 12,996/14 and 13,043/14, due to exclusion of contingences, related to tax installment program, on the consolidation of debts.

The Company has its corporate structure overseas subsidiaries, for which profits are taxed at income tax in the countries where they are domiciled by lower rates than those prevailing in Brazil.

From 2011 to 2015 some abroad subsidiaries generated profits amounting to R$4,025,071, in case tax authorities understand that these profits have already been distributed and, therefore, additional taxation in Brazil, if due, would amount approximately to R$1,356,111 in income tax and social contribution. The Company, based on its legal counsel’s opinion, assessed the likelihood of loss in a potential challenge by tax authorities as possible and, therefore, no provision was recognized in the financial statements.

· Law 12.973/14

Law 12.973, enacted in May 2014, brought significant changes to tax legislation, which among others, revoked the Transition Tax Regime (RTT).Theses changes directly impact the determination of the income tax and social contribution basis. As from 2015, the application of the Law is mandatory and CSN applied the Law´s requirements.

· Impairment test - Deferred taxes

CSN approved by the Board of Directors´ Meeting of November 6 th2015, a study to demonstrate the generation of future taxable income with which it is expected that the credits currently registered in the balance sheet are offset.

The test was performed considering only the parent company, since the other group companies have no relevant credits for purposes of this test. The parent company consists of the following businesses:

• Flat Steel Brazil;

• Long Steel Brazil;

• Mining

• Cement;

• Investments in other entities.

The study was prepared based on the CSN´s financial model of long-term and considered several scenarios which vary according to different macroeconomic and operating assumptions. Furthermore, the model considers a combination of assets sales scenario and liquidity events in order to achieve a specific amount of resources to CSN allowing a leverage reduction of and consequently, the reduction of financial expenses.

In addition, a sensitivity analysis of tax credits utilization considering a change in macroeconomic assumptions, operational performance and liquidity events took place. This sensitivity analysis showed that the consumption of credits is sensitive to exogenous issues and outside the Company's control.

Thus, considering the study´s results, which indicates the probable future taxable income to compensate the deferred income tax and social contribution balances recognized until June 30, 2015, the Board of Directors agreed to not record the deferred income tax and social contribution as from the 3rd quarter of 2015. If we had recorded the deferred income tax and social contribution, on the second quarter its amount would be R$1.09 billion. Additionally, the study projects the compensation of the residual balance amounting R$3,229 million for the next periods according to the schedule below:

*In millions of reais*		Parent Company
2016		686
2017		622

16.a) Tax Recovery Program (Federal Refis)

· Federal Law 11.941/09 Tax Installment Payment Program

In November 2009 the Company joined the Tax Installment Payment Program introduced by Law 11.941/09, aiming at regularizing tax liabilities through a special payment system and installment of tax obligations and social security.

The Company indicated to liquidate immediately tax debts linked to judicial deposits. The Company awaits the approval by the Federal Revenue Service (RFB) and the National Treasury Attorney General’s Office (PGFN) of these amounts, which total R$9,942.

National Minerals SA (NAMISA), incorporated by Congonhas Ores on December 31, 2015, and now consolidated in these financial statements at December 27, 2013 and November 25, 2014 has chosen to include some debts in the program installment introduced by Law 11,941 / 2009, due to the reopening of the deadlines for accession brought by Law No. 12,865 / 13 and 12,996 / 14, respectively.

· Installment Payment Program, Federal law 12.865/13

NAMISA also chose to include in the tax installment plan established by Article 40 of Law No. 12,865 / 13, the income tax debts and based on the profits of subsidiaries located abroad from 2009 to 2012, resulting from the application of Article 74 MP 2158-35 / 2001.

Some Group companies have installment payment plans with the Federal Revenue Service and state tax authorities.

The provision for tax, social security, labor, civil and environmental liabilities was estimated by management and is mainly based on the legal counsel’s assessment. Only proceedings for which the risk is classified as probable loss are accrued. This provision includes tax liabilities resulting from lawsuits filed by the Company, subject to SELIC (Central Bank’s policy rate).

Tax lawsuits

The main tax lawsuits assessed by the outside legal counsel as probable losses to which CSN or its subsidiaries are parties are as follows: (i) Municipal tax assessments (ISS) incident in lease contracts; (ii) ICMS Assessment Notice for the alleged nonpayment of this tax on product imports; (iii) Tax Forfeiture to collect ICMS reported but not paid; (iv) collection of income tax and social contribution for the offset of nonexistent tax credits.

Labor lawsuits

As of December 31, 2015, the Group is a defendant in 7,541 labor lawsuits, for which a provision has been recorded in the amount of R$478,611 (R$444,243 as of December 31, 2014). Most of the claims relate to subsidiary and/or joint liability, salary equalization, health hazard premiums and hazardous duty premiums, overtime pay, difference in the 40% fine for the severance pay fund (FGTS) related to period prior to retirement and as a result of federal government economic plans, 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 2001 to 2003.

During the year ended December 31, 2015 there were addition or write-off movements in labor lawsuits, due to court orders issued to terminate lawsuits 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 on-the-job accidents, occupational diseases and contractual litigation related to the industrial activities of the Group, real estate actions, healthcare plan, and reimbursement of costs incurred in labor courts. For lawsuits involving civil matters, a provision has been recognized in the amount of R$128,451 as of December 31, 2015 (R$106,143 as of December 31, 2014)

Environmental lawsuits

In general these proceedings arise from alleged damages to the environment related to the Company’s industrial activities. For lawsuits involving environmental matters, a provision has been recognized in the amount of R$17,646 as of December 31, 2015 (R$3,981 as of December 31, 2014)

In July 2012 the Company received a legal notice in the lawsuit filed by the State Attorney's Office of the State of Rio de Janeiro, related to Volta Grande IV district in the city of Volta Redonda-RJ, claiming, among others, the removal of two industrial waste cells and 750 (seven hundred and fifty) homes. This lawsuit is classified as probable loss risk, but there is not, until the moment, a complete diagnostic of the risks and so the Company has not estimated the costs for those claims.

As a result of the lawsuit mentioned in the paragraph above, after August 2012 the Company received legal notices related to some lawsuits filed by one of the dwellers of the Volta Grande IV district, who claims the payment of compensation for property damages and pain and suffering, whose amounts are illiquid at the moment, and this lawsuit is classified as possible loss risk.

On the same matter (Bairro Volta Grande IV), in August 2013 the Company received a subpoena about the lawsuits filed by the Federal Public Prosecution Office (Federal Courts), which has the same claim of the lawsuit filed by the State Public Prosecution Office, described above. This new lawsuit is classified as possible risk of loss since the trend is that the State courts’ decision prevails also in the Federal courts. The risk amount in this new lawsuit is the same of the lawsuit filed by the State Public Prosecution Office.

The assessments made by the legal counsel define these administrative and judicial proceedings as entailing risk of possible loss and, therefore, no provision was recorded in conformity with Management’s judgment and accounting practices adopted in Brazil.

Environmental lawsuits

The environmental processes present high complexity for estimating the amount at risk, should be taken into consideration, among various aspects, procedural development, the extent of damage and the projection of

repair costs.

During the second quarter 2015, in line with the Company's accounting policy of prognostic losses of ongoing processes, the management has reevaluated its environmental contingencies, supported by its internal and external legal counsel.

As a result of this work, there was an increase of the possible risk of loss amounting R$ 244,022.

There are other environmental processes for which it is not yet possible to assess the risk and contingency value due to the aforementioned complexity estimation, the peculiarities of the matters involving them and also their procedural steps.

18. PROVISION FOR ENVIRONMENTAL LIABILITIES AND ASSET RETIREMENT OBLIGATIONS

The balance of the provision for environmental liabilities and asset retirement obligation - ARO is as follows:

		Consolidated		Parent Company
	12/31/2015	12/31/2014	12/31/2015	12/31/2014
Environmental liabilities	262,290	211,544	259,115	211,544
Asset retirement obligations	66,641	26,995		21,718
	328,931	238,539	259,115	233,262

18.a) Environmental liabilities

As of December 31, 2015, there is a provision recognized for expenditures relating to environmental investigation and recovery services for potentially contaminated areas surrounding establishments in the States of Rio de Janeiro, Minas Gerais and Santa Catarina. Estimated expenditures will be reviewed periodically and the amounts already recognized will be adjusted whenever necessary. These are Management’s best estimates based on the environmental remediation studies and projects. This provision is recognized as other operating expenses.

The provision is measured at the present value of the expenditures required to settle the obligation, using a pretax rate that reflects current market assessments of the time value of money and the specific risks of the obligation. The increase in the obligation due to passage of time is recognized as other operating expenses.

The long-term interest rate used to discount the provision to present value through December 31, 2015 was 10.00%. The liability recognized is periodically updated based on the general market price index (IGPM) for the period.

Some contingent environmental liabilities are monitored by environmental department were not recorded in provisions due to its characteristics, they do not meet the recognition criteria present in CPC 25.

18.b) Asset retirement

Asset retirement obligations refer to estimated costs for decommissioning, retirement or restoration of areas upon the termination of activities related to mining resources. The initial measurement is recognized as a liability discounted to present value and subsequently through increase in expenses over time. The asset retirement cost equivalent to the initial liability is capitalized as part of the carrying amount of the asset, being depreciated over the useful life of the asset.

The accounting balances that refer to the provision for decommissioning were transferred to Congonhas Minérios,

The increase of liabilities in the period is due to an update on estimated cost of closing iron ore mines.

In 2015, the Company completed a new certification of iron mineral reserves in the Casa de Pedra and Engenho mines. This certification, prepared by a specialized company, has certified reserves of 3,021 million tons of iron ore, which represents an increase of 85% compared to the amounts certified in the last audit on April 2007.

Therefore, it indicated a need to review liabilities and update assumptions for mine closure, completion of mining activities in the future and decommissioning of assets linked to the mine, the result is an increase of liabilities amounting R$ 39,646.

Overseas, Lusosider, which is based in Portugal, also produces metal sheets, as well as galvanized steel. CSN LLC in the U.S.A. meets local market needs by supplying cold rolled and galvanized steel. 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 and has an installed production capacity of 1.1 million metric tons of steel/year.

In January 2014 the production of long steel products started with a capacity of 500,000 metric tons per year, which will consolidate 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 MG, the Casa de Pedra mine in Congonhas, MG, as well as Congonhas Minérios S.A., 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 activities from December 2015. In this context, the new company, called Congonhas Minérios S.A., holds the TECAR concession, the Casa de Pedra mine and all the shares of Namisa, which was incorporated on December 31, 2015.

Moreover, CSN controls a Estanho de Rondônia S.A. company mining units and tin casting.

· 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 operate the former Northeast Network of the RFFSA in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas.

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, 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, and carries CSN’s export products to the ports of Itaguaí and Rio de Janeiro. Its volumes of cargo carried account for approximately 28% of the total volume carried by the Southeast railroad system.

101

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–Recife, and Propriá–Jorge Lins (Network I) sections, whose concession goes until 2027, held by FTL; and ii) Network II, which comprises the Missão Velha–Salgueiro, Salgueiro–Trindade, Trindade– Eliseu Martins, Salgueiro–Porto de Suape, and Missão Velha–Porto de Pecém sections, whose concession goes until 2057 or until the return of the investment adjusted by 6.75% of the sections, held by TLSA.

The Network links up with the main ports in the region, offering an important competitive advantage by means of opportunities for combined transportation solutions and logistics projects tailored to customer needs.

II. Port Logistics

The Port Logistics Segment consolidates the operation of the terminal built during the post-privatization period of the ports, Sepetiba Tecon.. 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 excellent depths of 14.5 meters in the 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, at present with capacity for handling 480 thousand containers and 30 million metric tons per year of bulk cargo.

· 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. For fuel the Central Unit uses the residual gases produced by the steel mill itself. Through these three power generation assets, CSN obtains total rated capacity of 430 MW.

· Cement

The cement division consolidates the cement production, distribution and sale operations, which use the slag produced by the Volta Redonda plant’s blast furnaces. In 2011, the clinker used in cement production was acquired from third parties; however, at the end of 2011, with the completion of the first stage of the Arcos Clinker plant, MG, this plant already supplied the milling needs of CSN Cimentos in Volta Redonda.

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.

102

· Profit per segment

Beginning 2013, the Company no longer proportionately consolidates joint ventures Namisa, MRS and CBSI. For segment information preparation and presentation purposes, Management decided to maintain the proportionate consolidation of the joint ventures, as historically presented. For consolidated profit reconciliation purposes, the amounts of these companies were eliminated in the column “Corporate expenses/elimination”.

For the 2015 closure, after the combination of mining assets (Casa de Pedra, Namisa and Tecar), the consolidated results shall consider all of this new company.

(*) The ore sales volumes presented in this note take into consideration Company sales and the interest in its subsidiaries and joint ventures, corresponding Namisa 60% from January to November and Namisa 100% on December.

Adjusted EBITDA is the measurement based on 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 (costs), income tax and social contribution, depreciation and amortization, equity in results of affiliated companies, and other operating income (expenses), plus the proportionate EBITDA of joint ventures.

Even though it is an indicator used in segment performance 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 entities.

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
	12/31/2015	12/31/2014
Profit (loss) for the year	1,615,951	(112,267)
Depreciation (Note 10 a)	1,135,772	1,245,131

(*) 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 included in the calculation of recurring operating cash generation.

27. EMPLOYEE BENEFITS

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, presided over by the president of the pension fund and made up of ten members, six chosen by CSN in its capacity as main sponsor of CBS 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. Employees hired after that date can only join the new Mixed Plan. In addition, all active employees who were participants of the former defined benefit plans had the opportunity to switch to the new Mixed Plan.

104

As of December 31, 2015 CBS had 33,065 participants (34,426 as of December 31, 204), of whom 18,430 were active contributors (19,279 as of December 31, 2014), 13,965 were retired employees (14,379 as of December 31, 2014), and 670 were related beneficiaries (788 as of December 31, 2014). Out of the total participants as of December 31, 2015, 12,091 belonged to the defined benefit plan, 14,960 to the mixed plan, 1,595 to the CBSPrev Namisa plan, and 4,419 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, 2015 CBS held 20,143,031 common shares of CSN (12,788,231 common shares as of December 31, 2014). The total plan assets of the entity amounted to R$4.5 billion as of December 31, 2015 (R$4.2 billion as of December 31, 2014). The administrators of the CBS funds seek 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.

Plan Assets are all available assets and the benefit plans’ investments, not including the amounts of debts to sponsors.

For the defined benefit plans “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 years ended December 31, 2014 and 2015, CSN did not have to pay the installments because the defined benefit plans posted actuarial gains for the period.

27.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 sick pay to participants on Official Social Security leaves of absence and further ensures payments of savings fund, funeral allowance and pecuniary aid. This plan was discontinued on October 31, 1977 when the new supplementary plan based on average salary took effect.

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 the benefits of sick pay, 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. This plan was discontinued on October 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.

105

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.

27.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”).

27.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.

29.c) Projects and other commitments

· Transnordestina project

The Transnordestina project includes building 1,753 km of new, next-generation, wide-gauge tracks. The project posts a 55% progress and completion is estimated for 2017 (completion period currently under review and discussion with the responsible agencies). The Company expects that the investments will permit Transnordestina Logística S.A. to transport of several products, such as iron ore, limestone, soy, cotton, sugarcane, fertilizers, oil, and fuel. The concessionaire of the Transnordestina project holds the concession through no longer than 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 permits, purchased part of the equipment, contracted some of the services, 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) Permanent Track Use contracts, and (iv) interest in the capital of 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. Should additional funds be required, they will be provided by CSN and/or third parties under Permanent Track Use contracts.

The budget to conclude the project is under review, currently it is being analyzed by the competent agencies (shareholders), and it is expected that the reviewed budget will be 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 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 collateral letter of 1.25% issued to BNB and the corporate guarantee of 1.25% pledged to BNB). Under the FDNE charter, approved by Federal Decree 6,952/2009, and the Investment Agreement entered into with the public shareholders/ financiers, 50% of the debentures should be converted into TLSA shares.

30. 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 CSN 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 Coverage, Fleet Vehicles, D&O (Civil Liability Insurance for Directors and Officers), General Civil Liability, Engineering Risks, naming Risks, Export Credit, Performance Bond and Port Operator’s Civil Liability.

In 2015, after negotiation with insurers and reinsurers in Brazil and abroad, an insurance policy was issued for the contracting of a policy of Operational Risk of Property Damages and Loss of Profits, with effect from September 30, 2015 to September 30, 2016. Under the insurance policy, the LMI (Maximum Limit of Indemnity) is US$600,000,000 and covers the following units and subsidiaries of the Company: Presidente Vargas, Congonhas Minérios, CSN Handel and Namisa Handel. CSN takes responsibility for a range of retention of US$375 million in excess of the deductibles for property damages and loss of profits.

In view of their nature, the risk assumptions adopted are not part of the scope of an audit of the financial statements and, accordingly, were not audited by our independent auditors.

31. ADDITIONAL INFORMATION TO CASH FLOWS

In 2015, the Company incorporated the subsidiary CSN Cement and realized the drop down of Casa the Pedra, Tecar, investment in Namisa and MRS assets. Part of the net assets, shown in note 9, is not included in the statement of cash flows.

Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the Company’s preparation and fair presentation of the financial statements 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 internal control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the individual and consolidated financial statements referred to above present fairly, in all material respects, the individual and consolidated financial position of Companhia Siderúrgica Nacional as of December 31, 2015, its individual and consolidated financial performance and its cash flows for the year then ended, in accordance with accounting practices adopted in Brazil and with International Financial Reporting Standards – IFRS, as issued by the International Accounting Standards Board – IASB.

Emphasis of matter

Restatement of corresponding values

The individual and consolidated values, related to the balance sheet as of December 31, 2014 and the statement of cash flows for the year then ended, presented for comparative purposes, are being restated due to the matter described in note 2.a.a).

Other matters

Statements of value added

We have also audited the individual and consolidated statements of value added (“DVA”) for the year ended December 31, 2015, prepared under the responsibility of the Company’s Management, the presentation of which is required by Brazilian Corporate Law for publicly-traded companies, supplemental information for IFRS, which do not require the presentation of DVA. These statements were subject to the same auditing procedures described above, and, based on our opinion, are fairly presented, in all material respects, in relation to the financial statements taken as a whole.

The accompanying individual and consolidated interim financial information has been translated into English for the convenience of readers outside Brazil.
