CSN’s Consolidated Results

· Net revenue totaled R$4,008 million in 1Q16, 9% up on 4Q15 and 1% down on the same period last year. Regarding 4Q15, the increase was due to the higher sales volume in the steel and mining segments, offsetting the decrease in the average steel and mining prices, which suffered the additional impact of BRL appreciation. Compared with 1Q15, the reduction was a result of lower sales volume in the steel segment.

· COGS amounted to R$3,082 million, 6% down the previous quarter and 2% less than in 1Q15. The year-on-year reduction was mainly due to lower steel and mining segments unit costs.

· First-quarter gross profit came to R$926 million, 21% more than in 4Q15, while the gross margin widened by 2p.p. to 23%. In comparison with 1Q15, gross profit fell by 6% and the gross margin narrowed by 2p.p., from 25% to 23%.

· Selling, general and administrative expenses totaled R$611 million in 1Q16, 12% and 49% up on 4Q15 and 1Q15, respectively, chiefly due to higher freight (related to distribution costs), due to the increase in iron sales and the higher CIF sales model, and personnel expenses.

· Other operating income (expenses) was a net expense of R$127 million in 1Q16, versus expense of R$214 million in 1Q15. Most of the amount in question referred to expenses with labor provisions and judicial deposits. The positive result of R$ 2,798 registered in 4Q15 was due to the Business Combination effect in the mining segment.

· The proportional net financial result was negative by R$922 million in 1Q16, due to: i) financial expenses (excluding the exchange variation) of R$844 million; ii) the negative exchange variation result of R$329 million; and iii) financial revenue of R$252 million.

100% in Congonhas Minérios, 37.27% in MRS and 50% in CBSI as of December 2015.

· CSN’s equity result was a positive R$45 million in 1Q16, versus a negative R$55 million in 4Q15 and a positive R$398 million in 1Q15, chiefly due to MRS’s equity result in the 1Q16 and 4Q15, and Namisa’s equity result in the 1Q15. Namisa ceases to exist from this quarter onwards due to the business combination of its mining assets. The table below presents a breakdown of this item:

· CSN recorded a first-quarter net loss of R$777 million, versus quarter loss of R$461 million in 4Q15 and net income of R$392 million in 1Q15. The worsening in this result, compared with 4Q15, is explained by the gains registered with the conclusion of the mining segment Business Combination last quarter.

Foreign Exchange Exposure

Net foreign exchange exposure generated by the difference in dollar-denominated assets and liabilities, contracted derivatives and hedge accounting booked by CSN totaled US$114 million on March 31, 2016. The derivatives contracted form a long USD position achieved through the purchase of NDFs (Non-Deliverable Forwards). The hedge accounting adopted by CSN correlates the projected export flows in dollars with part of the future debt maturities in the same currency. As a result, the exchange variation of part of dollar-denominated debt is temporarily recorded under shareholder’s equity, being transferred to the income statement when the dollar revenue from these exports is received.

Working Capital

In order to calculate working capital, CSN adjusts its assets and liabilities as shown below:

· Accounts Receivable: Excludes Dividends Receivable, Advances to Employees and Other Credits.

· Inventories: Includes Estimated Losses and excludes Spare Parts which is not part of the cash conversion cycle, and will be subsequently booked under Fixed Assets when consumed;

· Recoverable Taxes: Composed only of Income (IRPJ) and Social Contribution (CSLL);

· Taxes Payable: Composed of Taxes Payable under Current Liabilities plus Taxes in Installments;

Third Parties Slabs	69	64	0	-			-
Total Rolled Products	1,020	952	746	(22%)			(27%)

· COGS came to R$2,300 million in 1Q16, a slight 1% increase over 4Q15.

· The parent company’s production cost reached R$1,343 million in 1Q16, 19% down on 4Q15, chiefly due to the decrease in the consumption of imported raw material as a result of the extinguishing of blast furnace 2 and the startup of coke batteries, thus reducing the fuel rate, in addition to the lower electricity consumption and a downturn in maintenance expenses.

· Slab production costs decreased 1.4%, to US$272/t from US$276/t in 4Q15. As a result, CSN maintained its position among those steel companies with the lowest slab costs in the world.

· Adjusted EBITDA amounted to R$420 million in 1Q16, 89% up on the R$222 million recorded in 4Q15, accompanied by an increase of 6p.p. in the margin, which widened from 9%, in 4Q15, to 15%.

Mining

In 1Q16, the seaborne iron ore market was positively impacted by the greater availability of credit and the recovery of construction activities in China, led by investments in new real estate projects. The improvement in demand led to higher prices and healthier margins for the local steel producers, as well as encouraging the build-up of inventories. In addition, seasonal factors, such as higher rainfall in Australia and Brazil, as well as the rigorous Chinese winter, played an important role in reducing the iron ore supply base.

1. DESCRIPTION OF BUSINESS

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

CSN is listed on the São Paulo Stock Exchange (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 steelworks (“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 Terminal de Carvão e Minérios do Porto de Itaguai - TECAR, a solid bulk terminal, one of the four terminals that compose the Port of Itaguai, located in Rio de Janeiro. Imports of coal and coke are held through this terminal and directed to the steel industry of CSN.

From November 30, 2015 the Company has transferred its mining assets, together with its logistical infrastructure, which includes the mine Casa de Pedra and the right to operate the terminal TECAR, to its subsidiary CSN Mineração S.A. (“CSN Mineração”) (Former Congonhas Minérios S.A.). On the same date, started to control Nacional Minérios S.A. (NAMISA) through a business combination transaction.

The Company´s mining activities also comprises tin exploitation, which is based in the State of Rondônia, this facility 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 Steelworks (UPV) 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, located in the State of Minas Gerais, to satisfy the needs of UPV as of the cement plant.

b) Statement of income and statement of comprehensive income at March 31, 2015

The Company has not restated the others statements of March 31, 2015 since the changes in those tables were not

material.

2.e) Restatement of the Quarterly Financial Information for the three-month period ended March 31, 2016, previously restated on November 14,2016.

In addition to the detailed review of the business combination transaction explained in item (a) below, the Company’s management performed a thorough review of various components and transactions, including the studies that support the recognition and maintenance of the amounts of long-lived assets, such as investments in subsidiaries and associates, goodwill, property, plant and equipment and tax credits. As a result of this review, a long-lived asset whose realization depends on projections with observable assumptions was revalued and its expected realization was adjusted. Accordingly, the financial statements for the year ended December 31, 2015, originally dated March 28, 2016 and restated on November 14, 2016 due to adjustments in non-controlling interests, were restated for the second time as a result of the detailed review mentioned above, which resulted in material adjustments to the following items:

(a) Business combination between CSN Mineração and NAMISA; and

(b) Expected realization of income tax and social contribution tax credits.

We present below further details on the adjustments that led management to opt for the second restatement of the financial statements for the year ended December 31, 2015.

a. Business Combination

The Company is restating the balances of the financial statements for the year ended December 31, 2015, as a result of a detailed review of all aspects of the business combination occurred on November 30, 2015, by which the Company’s mining activities were restructured and concentrated on a primary entity, CSN Mineração S.A. This review occurred after the first restatement, on November 14, 2016, of those financial statements resulting from a change in the interpretation of the gains attributed to owners and to non-controlling, as disclosed in note 2.a.b, of those financial statements.

Within this context, the Company identified errors in certain assumptions used in the fair value determination of the entities involved in the transaction, Nacional Minérios S.A. (NAMISA) and CSN Mineração, as well as in the accounting for the clause of the Investment Agreement signed in December 2014 that approached the treatment to be given to NAMISA’s assets excluded from the transaction, Fernandinho, Cayman and Pedras Pretas (“excluded assets”). As per that clause, Fernandinho, Cayman and Pedras Pretas assets included in the fair value determination of NAMISA shall be transferred directly to any entity other than CSN Mineração. By mistake, those assets were included within the net assets of NAMISA contributed to CSN Mineração and, in a subsequent act, were transferred from CSN Mineração to another entity, Minérios Nacional (current corporate name of Mineração Nacional S.A.). And finally, the review appointed to a change in the interpretation of the determination of the gain or loss in the pre-existing relationship between the acquirer and the acquiree entities as established in the accounting pronouncement CPC15/IFRS3.

The Company opted to restate the year ended December 31, 2015 as comparative information in the financial statements for the year ended December 31, 2016. Thus, the reasons that led the Company to restate the business combination performed in 2015 are described in detail in Note 2 (ab) to the financial statements for the year ended December 31, 2016, which are being approved on the same date

b. Estimated losses of deferred income tax and social contribution credits

The Company is restating the balances of deferred income tax and social contribution credits of its financial statements for the year ended December 31, 2015 after the technical review, during 2016, of the negative and positive aspects that supported their maintenance. The main change in the decision for this restatement is the exclusion of the sale of certain non-core assets from the studies of recovery of credits, reducing the future taxable base of projections, and the higher weight attributed to the observable evidence of tax losses existing in the last years, according to the interpretation given by accounting standard IAS 12 / CPC 32. As established in the standard, in the case of existence of recent history of successive losses or losses alternated in several years, this becomes the primary evidence for assessing the maintenance or recording of tax credits to offset against future taxable profits, with the study of projections of these profits remaining as a source of secondary evidences and with lower weight in the assessment.

Thus, the Company elected to maintain in assets an amount of tax losses and negative basis of social contribution equivalent to 30% of the deferred income tax liability balance, an amount that will be used as the deferred tax liability becomes current income tax payable. With this, the total credits arising from temporary differences were accrued and maintained in inventory of credits in the Company’s tax books for future utilization. This system of maintenance of tax credits equivalent to 30% of the deferred income tax liability will remain until a new history of taxable profits is formed and the studies of projections of future profits become again primary evidences for the recording of tax credits, when the Company will recognize the temporary differences and higher amounts of tax losses and negative basis of social contribution losses that will be utilized to offset income tax payable arising from future taxable profits.

The adjustments in items (a) and (b) that generated the restatement of the financial statements for the year ended December 31, 2015, which consequently impacted the three-month period ended March 31, 2016 are detailed in the table below:

· Reduce of financial leverage

With the primary objective of reducing the Company’s financial leverage, Management is committed to a plan to dispose of a set of assets, however, it is not possible to confirm that the sale within a period of 12 months is highly probable for any of the assets contemplated. The Company considers several sales scenarios that vary according to different macroeconomic and operational assumptions. In this context, the Company did not segregate and did not reclassify such assets in the financial statements as discontinued operations in accordance with CPC 31 (IFRS 5).

The sale of the subsidiary Metalic Nordeste, as mentioned in note 29 (subsequent events), is part of the Company's effort with the plan of assets disposal and demonstrates Management's commitment with this plan.

· 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 has been 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.

The table below shows a summary of the hedging relationships as of March 31, 2016:

(*) The effect on the financial result was recorded in net foreign exchange rates.

(1) During the designation on August 2015, we reviewed the future export projections and identified that the amount of US$ 9 million designated previously were not highly probable due to Platt’s quotation reduction. Therefore, the hedge relationship was discontinued from August 2015. The exchange rate of the effective period remains recorded in Stockholders' Equity until the time of debt settlement.

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

· Net investment hedge in foreign subsidiaries

CSN has foreign exchange exposure in Euros arising from a loan made by a foreign subsidiary 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 the exchange variation of the net assets of the foreign operation directly affected the equity in other comprehensive income.

As from September 1^st, 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 March 31, 2016 are:

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

The Company has overseas subsidiaries in its corporate structure, 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 1^st quarter 2016 some abroad subsidiaries generated profits amounting to R$4,039,308. If for some reason tax authorities understand that these profits have already been distributed, the additional taxation in Brazil would amount approximately to R$1,373,365 in income tax and social contribution.

The Company, based on its legal counsel’s opinion, assessed the likelihood of loss in a potential claiming by tax authorities which resulted in a possible risk of loss and, therefore, no provision was recognized in the financial statements.

14.c) Income tax and social contribution recognized in shareholders' equity:

18.f) Policy on investments and payment of interest on capital and dividends

At a meeting held on December 11, 2000, the Board of Directors decided to adopt a profit distribution policy which, after compliance with the provisions in Law 6,404/76, as amended by Law 9,457/97, will entail the distribution of all the profit to the Company’s shareholders, provided that the following priorities are observed, irrespective of their order: (i) carrying out the business strategy; (ii) fulfilling its obligations; (iii) making the required investments; and (iv) maintaining a healthy financial situation of the Company.

18.g) Earnings/(loss) per share:

Basic earnings per share were calculated based on the profit attributable to the owners of CSN divided by the weighted average number of common shares outstanding during the year, excluding the common shares purchased and held as treasury shares, as follows:

		Parent Company
	03/31/2016 Restated	03/31/2015
	Common Shares
Net (loss) / Gain of the period
Attributable to owners of the Company	(785,191)	392,056
Weighted average number of shares	1,357,133	1,357,202
Basic and diluted EPS	(0.57857)	0.28887

The Company does not hold potential dilutable outstanding ordinary shares that could result in dilution of earnings per share.

26. 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, warranty 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 million and covers the following units and subsidiaries of the Company: Presidente Vargas steelworks, CSN Mineração, Sepetiba Tecon, and CSN Mining. 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.

In February 2017, the Company was notified of the judgment of the Amendment of Judgment filed due the CARF’s decision on case 19515.723039 / 2012-79, in which the Federal Revenue Service of Brazil challenges the capital gain on the alleged sale of 40% of NAMISA (currently CSN Mineração S.A.). The CARF, in short, agreed with the infringement notice. The Company, however, is taking of the lawfulness of the operation and, therefore, is evaluating the appropriate legal and procedural measures to reverse the decision. It is important to emphasize, finally, that this decision does not alter the assessment of loss on the case, which remains as possible, see note 15.

· Significant development of Proceeding No. 19515.723053/2012-72

Page 88

(CONVENIENCE TRANSLATION INTO ENGLISH FROM THE ORIGINAL PREVIOUSLY ISSUED IN PORTUGUESE)
ITR –– Quarterly Financial Information - March 31, 2016 – CIA SIDERURGICA NACIONAL	Version: 1

The Superior Board of Tax Appeals of CARF ruled on 03/14/2017 a special appeal by the National Treasury against a previous decision favorable to Namisa, (currently CSN Mineração S.A.) filed in case No. 19515.723053 / 2012-72, in which the Federal Revenue Service of Brazil challenges the deductibility of goodwill amortization expenses arising from the operation carried out with the Asian Consortium in 2008. The CARF, in summary, agreed with the infringement notice. The Company, however, has absolute conviction of the lawfulness of the operation and, therefore, Is taking legal measures. It is important to emphasize, finally, that this decision does not alter the assessment of loss of the case, which remains as possible, see note 15.

• Cautionary decision – TCU – Transnordestina Logistica

The Brazilian Court of Auditors (“TCU”) issued a cautionary decision in May 2016 referred to the action TC 012.179/2016 by which it prohibited new transfers of Government funds to TLSA to be made by Valec Engenharia, Construções e Ferrovias S.A., Fundo de Investimento do Nordeste – FINOR, Fundo Constitucional de Financiamento do Nordeste – FNE, Fundo de Desenvolvimento do Nordeste – FDNE, Banco Nacional de Desenvolvimento Econômico e Social – BNDES and BNDES Participações S.A. – BNDESPar. After TLSA appeal against the cautionary decision and further details to have been provided, in June 2016 the preliminary injunction given by TCU was unanimously revoked by the Court and the continuity of the transfer of funds was re-established.

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

There is an administrative procedure before the Transportation National Agency (“ANTT”), that assesses the regular fulfilling by the grantee FTL of the obligations contained in the Concession Agreement. By an unilateral assessment, ANTT considered that FTL was not compliant with the Term of Conduct Adjustment (“TAC”) signed in 2013 alleging that FTL had not fulfilled the 2013 production plan. ANTT decided to set up an administrative proceedings to investigate the supposed unfulfillment of the concession agreement and, in the case of confirming irregularities, may apply several penalties, including the early termination of the concession agreement. The grantee filed its defense against the administrative proceedings and currently no new decisions have been taken.

· Independent investigation – Construction of the Long Steel Plant

Considering the mentioning of a Company’s officer in an article disclosed by the press, based on testimonials made before the Court, the Audit Committee decided to hire a specialized forensic service to conduct an external and independent investigation of the contractual relationship related to the construction of CSN’s Long Steel Plant (contract in which there would have been alleged improper payments, as bonus, as reimbursement of payments made to political parties supposedly requested by such officer) and to analyze the extent of the commercial relationship between contractor . The conclusion of the investigation is that nothing in the testimonials referred to above was confirmed, there being no contingencies arising from the matters investigated. Consequently, understands the Company that at this moment there is no basis to justify the setting up of a provision for losses or the disclosure of a contingency.

REPORT ON REVIEW OF INTERIM FINANCIAL INFORMATION

To the Board of Directors and Shareholders of

Companhia Siderúrgica Nacional

São Paulo - SP

Introduction

We have reviewed the accompanying individual and consolidated interim financial information of Companhia Siderúrgica Nacional (“Company”), included in the Interim Financial Information Form (ITR), for the quarter ended March 31, 2016, which comprises the balance sheet as at March 31, 2016, and the statement of profit and loss, statement of comprehensive income, statement of changes in equity and statement of cash flows for the three-month period then ended, including the explanatory notes.

Management is responsible for the preparation of the individual and consolidated interim financial information in accordance with CPC 21 (R1) and IAS 34 - Interim Financial Reporting, issued by the International Accounting Standards Board (IASB), as well as for the presentation of such information in accordance with the standards issued by the Brazilian Securities Commission (CVM), applicable to the preparation of Interim Financial Information (ITR). Our responsibility is to express a conclusion on this interim financial information based on our review.

Scope of review

We conducted our review in accordance with Brazilian and international standards on review of interim financial information (NBC TR 2410 and ISRE 2410 - Review of Interim Financial Information Performed by the Independent Auditor of the Entity, respectively). A review of interim financial information consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with the standards on auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion on the interim financial information

Based on our review, nothing has come to our attention that causes us to believe that the accompanying individual and consolidated interim financial information included in the ITR referred to above is not prepared, in all material respects, in accordance with CPC 21 (R1) and IAS 34 applicable to the preparation of Interim Financial Information (ITR) and presented in accordance with the standards issued by the Brazilian Securities Commission (CVM).

Emphasis of matter

Restatement of the interim financial information for the three-month period ended March 31, 2016

On November 14, 2016, we reissued the review report, without modification, on the Company’s individual and consolidated interim financial information for the three-month period ended March 31, 2016. As described in note 2.e), the interim financial information referred to above has been adjusted and is being restated to reflect the impacts arising from the restatement of the financial statements for the year ended December 31, 2015, relating to: (i) the accounting and fair value measurement adjustments upon the application of technical pronouncement CPC 15 (R1) - Business Combination and international standard IFRS 3 - Business Combination, issued by the IASB, concerning the business combination conducted by subsidiary Congonhas Minérios S.A. and (ii) the review of the recoverability analysis and adjustments to deferred income tax and social contribution balances.

Other matters

Statements of value added

We have also reviewed the individual and consolidated interim statements of value added (“DVA”) for the three-month period ended March 31, 2016, prepared under Management’s responsibility, the presentation of which is required by the standards issued by the Brazilian Securities Commission (“CVM”) applicable to the preparation of Interim Financial Information (ITR), and is considered as supplemental information for International Financial Reporting Standards (“IFRSs”), which do not require the presentation of a DVA. These statements were subject to the same review procedures described above and, based on our review, nothing has come to our attention that causes us to believe that they are not prepared, in all material respects, in relation to the interim financial information taken as a whole.

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