04.01 – NOTES TO THE FINANCIAL STATEMENTS

(In thousands of reais, except when otherwise indicated)

1. OPERATING CONTEXT

Companhia Siderúrgica Nacional (“CSN”) is engaged in the production of flat steel products, its main industrial complex being the Presidente Vargas Steelworks located in the City of Volta Redonda, State of Rio de Janeiro.

CSN is engaged in the mining of iron ore, limestone and dolomite, in the State of Minas Gerais and tin in the State of Rondônia to cater for the needs of the Presidente Vargas Steelworks, and it maintains strategic investments in railroad, electricity and ports, to optimize its activities.

For the purpose of establishing a closer approach to its customers and winning additional markets on a global level, CSN has a steel distributor with service and distribution centers extending from the Northeast to the South of Brazil, a two-piece steel can plant geared to the Northeastern beverage industry, a metal package plant with branches in the South and Southeast areas of Brazil, a galvanized steel plant supplying an automaker in Porto Real, in the State of Rio de Janeiro, and another in Araucária, in Paraná, to supply home appliances, in addition to a rolling mill in the United States and a 50% stake in another rolling mill in Portugal.

2. PRESENTATION OF THE FINANCIAL STATEMENTS

In compliance with the configuration of the form of the Quarterly Information, the Statements of Changes in Financial Position and of Cash Flows of the parent company and consolidated are presented in the item “Other information considered material by the Company”. Some information of the first quarter were reclassified for comparison purposes with the data of the current quarter, to comply with the CVM Resolution 489/05.

3. SIGNIFICANT ACCOUNTING PRACTICES

The Financial Statements were prepared in conformity with the accounting practices adopted in Brazil, as well as with the accounting standards and pronouncements established by the Brazilian Securities Commission.

(a) Statement of Income

The results of operations are determined on an accrual basis.

(b) Marketable securities

The investment funds have daily liquidity and have their assets valued at market as per instructions of the Central Bank of Brazil and CVM, since the Company considers these investments as securities retained for trading.

Fixed income securities are recorded at cost plus yields accrued through the balance sheet date, and do not exceed the market value, and investments overseas have a daily remuneration.

(c) Allowance for doubtful accounts

The allowance for doubtful accounts has been set up in an amount which, in the opinion of Management, suffices to absorb any losses that might be incurred in realizing accounts receivable.

(d) Inventories

Inventories are stated at their average cost of acquisition or production and on-going imports are recorded at their cost of acquisition, provided that they do not exceed their market or realization values.

(e) Other current and long-term assets

Other current and long-term assets are presented at their realization value, including, when applicable, income earned to the balance sheet date or, in the case of prepaid expenses, at cost.

(f) Investments

Investments in subsidiaries and jointly owned subsidiary companies are recorded by the equity accounting method, adjusted for any amortizable goodwill, if applicable. Other permanent investments are recorded at acquisition cost.

(g) Property, plant and equipment

The property, plant and equipment of the parent company is presented at market or replacement values, based on appraisal reports conducted by independent expert appraisal firms, as permitted by Deliberation #288 issued by the Brazilian Securities Commission on December 3, 1998. Depreciation is computed by the straight-line method, based on the remaining economic useful lives of the assets after revaluation. Depletion of the iron mine – Casa de Pedra is calculated on the basis of the quantity of iron ore extracted, and interest charges related to capital funding for construction in progress are capitalized for as long as the projects remain unconcluded.

(h) Deferred charges

The deferred charges are comprised of expenses incurred for development and implantation of projects that should generate a payback to the Company in the next few years, with the amortization applied on a straight-line basis based on the period foreseen for the economic return on the above projects.

(i) Current and long-term liabilities

These are stated at their known or estimated values, including, when applicable, accrued charges, monetary and foreign exchange variation incurred up to the balance sheet date.

(j) Employees’ benefit

In accordance with Deliberation #371, issued by the Brazilian Securities Commission, on

December 13, 2000, the Company decided to record the respective actuarial liabilities as from January 1, 2002, in accordance with the above-mentioned reported deliberation and based on studies by independent actuaries.

(k) Income Tax and Social Contribution

Income tax and social contribution on net income are calculated based on their effective tax rates and consider the tax loss carryforward and negative basis of social contribution limited to 30%, to compute the tax liability. Tax credits are set up for deferred taxes on tax losses, negative basis of social contribution on net income and on temporary differences.

(l) Derivatives

The derivatives operations are recorded in accordance with the characteristics of the financial instruments. Swap operations are recorded based on the operations’ net results, which are booked monthly in line with the contractual conditions.

Exchange options are adjusted monthly to market value whenever the position shows a loss. These losses are recognized as Company’s liability with the corresponding entry in the financial results. Options traded through exclusive funds are adjusted to market and futures contracts have their positions adjusted to market daily by the Futures and Commodities Exchange (“BM&F”) with recognition of gains and losses directly in results.

(m) Treasury Shares

The Financial Statements prepared in US dollars and in Euros were translated at the exchange rate in effect on June 30, 2006 – R$/US$2.1643 (R$/US$2.1724 on March 31, 2006) and EUR/US$1.2790 (EUR/US$1.2119 on March 31, 2006).

The gains and losses from this translation were accounted for in the income statements of the related periods, as equity accounting in the parent company and exchange variation in the consolidated entity. These financial statements were prepared applying the same accounting principles as those applied by the parent company.

In the preparation of the consolidated financial statements, the consolidated intercompany balances were eliminated, such as intercompany investments, equity accounting, asset and liability balances, revenues and expenses and unrealized profits resulting from operations among these companies.

Pursuant to the CVM Instruction #408/04 the Company consolidates the financial statements of the exclusive investment funds.

The reference date for the subsidiaries and jointly-owned subsidiaries financial statements coincides with that of the parent company.

The reconciliation between shareholders’ equity and net income for the period of the parent company and consolidated is as follows:


	Shareholders' equity		Net income for the half

	6/30/2006	3/31/2006	6/30/2006	6/30/2005

Such debentures were issued for the total value of issue of R$500,000. The credits from the negotiations with the financial institutions were received on December 22 and 23, 2003, amounting to R$505,029. The difference of R$5,029, resulting from the variation of the unit price between the date of issue and of the effective negotiation was recorded in Shareholders’ Equity as Capital Reserve, subsequently used for cancellation of treasury shares.

The balance of the face value of the 1^st tranche incurs compensation interest corresponding to 106.5% of Cetip’s CDI. The face value of the 2^nd tranche is adjusted by the IGP-M plus compensation interest of 10% p.a.. The maturity of the 1^st tranche is scheduled for December 1, 2006 and of the 2^nd tranche for December 1, 2008.

Fourth issuance

As approved at the Board of Directors Meeting held on December 20, 2005 and ratified on April 24, 2006, the Company issued, on February 1, 2006, 60,000 non-convertible and unsecured debentures, in one single tranche, in the unit face value of R$10. Such debentures were issued in the total issuance value of R$600,000. The credits from the negotiations with the financial institutions were received on May 3, 2006 amounting to R$623,248. The difference of R$23,248, resulting from the variation of the unit price between the issuance date and the effective negotiation was recorded in Shareholders’ Equity as Capital Reserve.

Compensation interest is applied to the face value balance of these debentures, representing 103.6% of the CDI Cetip, and the maturity of the face value is scheduled for February 1, 2012, without early redemption option.

The deeds for these issues contain certain restrictive covenants, which have been duly complied with.

15. FINANCIAL INSTRUMENTS

General considerations

The Company’s business includes flat steel products to supply domestic and foreign markets and mining of iron ore, limestone, dolomite and tin to supply the Presidente Vargas steelwork needs. The main market risk factors that can affect the Company’s business are as follows:

Exchange rate risk

Most of the revenues of the Company are in Brazilian Reais and, on June 30, 2006, R$7,892,236 (R$7,114,228 on March 31, 2006) of the Company’s consolidated debt of loans and financing were denominated in foreign currency. As a consequence, the Company is subject to changes in exchange rates and manages the risk of these rates fluctuations which affects the value in Brazilian Reais that will be necessary to pay the liabilities in foreign currency, using derivative financial instruments, mainly futures contracts, swaps and forward contracts, as well as investing a great part of its cash and funds available in securities remunerated by U.S. dollar exchange variation.

Credit risk

The credit risk exposure with financial instruments is managed through the restriction of counterparts in derivative instruments to large financial institutions with high quality of credit. Thus, management believes that the risk of non-compliance by the counterparts is insignificant. The Company neither maintains nor issues financial instruments with commercial aims. The selection of customers as well as the diversification of its accounts receivable and the control on sales financing terms by business segments are procedures adopted by CSN to minimize problems with its trade partners. Since part of the Companies’ funds available is invested in

Brazilian government bonds, there is exposure to the credit risk with the government. The amount invested in such instruments on June 30, 2006, was R$945,046 (R$465,804 on March 31, 2006).

The financial instruments recorded in the Parent Company’s balance sheet accounts on June 30, 2006, whose market value differs from the book value, are as follows:


	Book Value	Market Value

Loans and financing (short and long term)	9,697,362	9,930,906

On June 30, 2006, the consolidated position of outstanding derivative agreements was as follows:


	Agreement		Market value

	Maturity	Notional amount

Variable income swap (*)	7/28/2006	US$ 49,223 thousand	R$ 564,486

exclusive funds)	Jul/06	US$ 980,000 thousand	(R$ 153,725)

Yen swap	Dec/06	JPY 43,230,000 thousand	(R$46,909)

(*) Refers to non cash swap which, at the end of the contract, the counterpart shall remunerate at the variation of equity assets, as long as the Company’s subsidiary, CSN Steel, undertakes to remunerate the same reference updated value at the pre-fixed rate of 7.5% per annum.

Market value

The amounts presented as “market value” were calculated according to the conditions that were used in local and foreign markets on June 30, 2006, for financial transactions with similar features, such as: volume of the transactions and rates and maturity dates.

Mathematical methods are used presuming there is no arbitrage between the markets and the financial assets. Finally, all the transactions carried out in non-organized markets (over-the-counter market) are contracted with financial institutions previously approved by the Company’s Board of Directors.

The provision for contingencies estimated by the Company’s Management was substantially based on the appraisal of its tax and legal advisors. Such provision is only recorded for lawsuits classified as probable losses. Additionally, it includes tax liabilities stemming from actions taken by Company’s initiative, which are maintained and increased by Selic interest rates.

The Company is defending itself in other judicial and administrative proceedings (labor, civil, tax and environmental) in the approximate amount of R$1.9 billion. According to the Company’s legal counsel, there is a possible risk of losing these lawsuits, and therefore they were not provided for in accordance with accounting practices adopted in Brazil.

a) Labor Litigation Dispute:

On June 30, 2006, CSN was defendant in 7,281 labor claims (7,541 claims on March 31, 2006), which required a provision in the amount of R$25,819 (R$26,259 on March 31, 2006). Most of the lawsuits are related to joint and/or subsidiary responsibility, wages equalization, additional payment for unhealthy and hazardous activities, overtime and differences related to the 40% fine over FGTS (severance pay), and due to government’s economic policies.

The increase in labor claims as from 2004 is due to the request for the difference of 40% fine on the FGTS deposited amounts, in view of the understated inflation imposed by economic plans. The matter is still controversial, pending a uniform understanding.

The lawsuits related to subsidiary responsibility originate from the non-payment by the contracting companies of their labor obligations, which results in the inclusion of CSN in the lawsuits, as defendant, to honor on a subsidiary basis the payment of such obligations.

The number of lawsuits originated from subsidiary responsibility has decreased due to the procedures adopted by the Company in order to inspect and assure compliance with the wages and social charges payments, through the Contract Follow-up Center since 2000.

b) Civil Actions:

These are, mainly, claims for indemnities among the civil judicial processes in which the Company is involved. Such proceedings, in general, are originated from occupational accidents and diseases related to industrial activities of the Company. For all these disputes, the Company accrued the amount of R$13,281 on June 30, 2006 (R$13,281 on March 31, 2006).

c) Environmental Actions:

On June 30, 2006, the Company recorded a provision of R$36,132 (R$27,557 on March 31, 2006) for investment in environmental recovery expenditures.

d) Tax Litigation Dispute:

• Income Tax and Social Contribution

(i) The Company claims recognition of the financial and tax effects on the calculation of the income tax and social contribution on net income, related to Consumer Price Index – IPC understated inflation, which occurred in January and February 1989, by a percentage of 51.87% (“Plano Verão”).

In 2004, the proceeding was concluded and judgment was made final and unappealable, granting to CSN the right to apply the index of 42.72% (Jan/89), of which the 12.15% already applied should be deducted. The application of 10.14% (Feb/89) was deferred. The proceeding is now under accounting inspection.

On June 30, 2006, the Company recorded R$361,928 (R$361,928 on March 31, 2006) as judicial deposit and a provision of R$20,892 (R$60,573 on March 31, 2006), which represents the portion not recognized by the courts.

(ii) In February 2003, the tax authorities assessed the Company for the calculation of prior years’ IRPJ and CSL for compensating taxable losses over the limit of 30% of taxable income as provided for by law.

On August 21, 2003 a decision was rendered by the second panel of the Federal Revenue Office in Rio de Janeiro that cancelled such tax assessment, being the Company assessed again, by the tax authorities, for the same matter, in November 2003. The Company filed a refutation of this Assessment Notice which was not accepted in the lower court, was accepted in the appellate court on April 26, 2006, and such Tax Assessment was judged favorable to CSN, but the respective final court decision has not been published yet.

In March 2006, the Company kept provision related to items remaining from the second Tax Assessment amounting to R$197,463, and in June 30, 2006 the balance is zero.

(iii) The Company filed an action questioning the assessment of Social Contribution on Income on export revenues, based on Constitutional Amendment #33/01 and in March 2004 the

Company obtained an initial decision authorizing the exclusion of export revenues from said calculation basis, as well as the offsetting of amounts paid on these revenues as from 2001. The lower court decision was favorable and the proceeding is waiting for trial of the appeal filed by the Federal Government in the Regional Federal Court. On June 30, 2006, the amount of suspended liability and the offset credits based on the referred proceedings was R$640,271 (R$604,048 on March 31, 2006), which is added by the Selic rate.

• PIS/COFINS – Law 9,718/99

CSN is questioning the legality of Law 9,718/99, which increases the PIS and COFINS calculation basis, including the financial revenue of the Company. On June 30, 2006, provision amounts to R$306,074 (R$299,455 on March 31, 2006), which includes legal charges.

In February 1999, the Company obtained a favorable decision in the lower court. However, the 2^nd Regional Federal Court reversed the favorable decision. Later on, the Company appealed against this decision in the Supreme Court of Justice and is currently waiting for trial.

• CPMF

The Company questioned the CPMF requirement since the promulgation of the Constitutional Amendment #21/99. On May 31, 2006, an unfavorable decision to the Company was disclosed, and the referred proceeding was closed on June 30, 2006, when the Company settled the obligation related to the referred tax. On March 31, 2006, the Company maintained a provision in the amount of R$392,801.

• CIDE – Intervention Contribution in the Economic Domain

CSN disputes the legal validity of Law 10,168/00, which established the collection of the intervention contribution in the economic domain on the amounts paid, credited or remitted to non-resident beneficiaries, as royalties or remuneration of supply contracts, technical assistance, trademark license agreement and exploration of patents.

The Company recorded court deposits and its corresponding provision in the amount of R$23,061 on June 30, 2006 (R$22,924 on March 31, 2006), which include legal charges.

The lower court decision was unfavorable and the proceeding is currently under judgment at the 2^nd Regional Federal Court.

• Education Salary

The Company discussed the unconstitutionality of the Educational-Salary and the possible recovery of the amounts paid in the period from January 5, 1989 to October 16, 1996. The lawsuit was judged unfounded, and the Superior Court maintained its unfavorable decision, judgment made final and unappealable.

In view of this fact, the Company attempted to pay the amount due, and FNDE and INSS did not reach an agreement as to whom the amounts should be paid. A fine was also demanded, to CNS’ disagreement.

The Company filed new proceedings to question related to the above-mentioned facts and deposited in court the amounts due. In the first lawsuit, the 1^st degree sentence was partially in favor of CSN, with the fine being disregarded but not the SELIC rate. We presented counter-arguments to the defendant’s appeal and appealed in relation to the SELIC rate. No judgment has been made regarding the other lawsuits.

The provision on June 30, 2006 amounts to R$33,121 (R$33,121 on March 31, 2006).

• SAT - Workers’ Compensation Insurance

The Company understands that it must pay the “SAT” at the rate of 1% in all of its establishments, and not 3%, as determined by the current legislation. The amount provided as of June 30, 2006 totals R$85,663 (R$81,083 on March 31, 2006), which includes legal charges.

The lower court decision was unfavorable and the proceeding is under judgment of TRF of the 2^nd Region. Given the new understanding adopted by the Courts, the Company’s lawyers deem as probable the possibility of loss.

• IPI (Excise Tax) presumed credit on inputs

The Company brought an action pleading the right to the IPI presumed credit on the acquisition of exempted, immune, non-taxed inputs, or taxed at zero rate and in May 2003 an initial decision was obtained authorizing the use of said credits. This action is currently waiting for the sentence in lower court.

On June 30, 2006, the provision related to the total credits already offset and recorded under the Company’s liabilities amounted to R$895,687 (R$731,457 on March 31, 2006), adjusted by the Selic rate.

• IPI premium credit over exports

The Company brought an action claiming the right to the IPI premium credit on exports from 1992 to 2002 and in March 2003 a favorable decision was obtained authorizing the use of said credits. The Regional Federal Court - Appellate Court maintained the favorable decision for CSN.

Currently, CSN is waiting for the action to be redirected to the STF/STJ to have the argued appeal filed by the Internal Revenue Service.

On June 30, 2006, the provision referring to the total of credits already offset amounted to R$1,361,335 (R$963,296 on March 31, 2006), adjusted by the Selic rate.

• Other

The Company also made provision for several other lawsuits in respect of FGTS LC 110, COFINS Law 10,833/03, PIS Law 10,637/02 and PIS/COFINS Manaus Free-Trade Zone, in the amount of R$50,275 on June 30, 2006 (R$46,102 on March 31, 2006), which includes legal charges.

i. Paid-in capital stock

On July 7, 2005, at an Extraordinary Annual Meeting, CSN approved the cancellation of 14,849,099 shares held in treasury, with no reduction in the capital stock. The Company’s fully subscribed and paid-in capital stock of R$1,680,947 was then divided in 272,067,946 common book-entry shares, with no par value. Each share is entitled to one vote in the resolutions of the General Meeting.

ii. Revaluation reserve

This reserve covers revaluations of the Company’s fixed assets approved by the Shareholder’s Extraordinary General Meeting held December 19, 2002, and April 29, 2003, which were intended for determining adequate amounts for the Company’s fixed assets at market value, pursuant to the CVM Deliberation #288, dated December 3,1998. The objective of such procedure is for the financial statements to reflect assets value closer to their replacement value.

Pursuant to the provisions of CVM Deliberation 273, as of August 20, 1998, a provision for deferred social contribution and income tax was set up based on the balance of the revaluation reserve (except land), which is classified as a long-term liability.

The realized portion of the revaluation reserve, net of income tax and social contribution, is included for purposes of calculating the mandatory minimum dividend.

iii. Treasury shares

The Board of Directors approved on May 25, 2005 for a period of 360 days the purchase of 15,000,000 shares of the Company to be held in treasury and subsequent sale and/or

cancellation. Such authorization for repurchase finished on May 26, 2006, and treasury shares position on June 30 was as follows:

v. Investment policy and payment of interest on own capital/dividends

On December 13, 2000, CSN’s Board of Directors decided to adopt a policy of profit distribution, which, by observing the provisions of Law 6,404/76, altered by Law 9,457/97 implies the distribution of all the Company’s net profit to the shareholders, as long as the following priorities are preserved irrespective of their order: (i) corporate strategy, (ii) compliance with obligations, (iii) making the necessary investments and (iv) maintenance of a good financial situation of the Company.

19. INTEREST ON OWN CAPITAL

The calculation of interest on own capital is based on the change in the Long-Term Interest Rates over shareholders’ equity, limited to 50% of the income for the year before income tax or 50% of accumulated profits and profit reserves, and the higher between two limits may be used, pursuant to the prevailing laws.

In compliance with CVM Deliberation 207, as of December 31, 1996 and fiscal rules, the Company opted to record the interest on own capital the amount of R$90,494 in the first half of 2006 as counter entry of the financial expenses account, and revert it on the same account, not been shown on the income statement and not generating effects on net income after IRPJ/CSL, except as to the fiscal effects, these recognized under income tax and social contribution. The

Company’s management shall propose that the amount of interest on own capital be attributed to the mandatory minimum dividend.

23. OTHER OPERATING REVENUES

On January 22, 2006 an accident involving Blast Furnace number 3 took place, mainly affecting the powder collecting system and temporarily interrupting the equipment production. The Company has an insurance policy for loss of profits and equipment in the maximum amount of US$750 million. The cause of the accident had its coverage by the policy expressly recognized by the insurance companies, and Management believes that this amount is enough to recover any losses resulting from the accident.

Thus, the Company, based on studies and calculations prepared by independent consultants, hired by the insurance company, recorded in other operating income, in conservative basis, the amount of R$669,832 as indemnity estimate of loss of profits up to June 30, 2006.

Up to the closing date of this report the Company had received the partial payment of US$75 million on the account of this accident.

The equipment is going through final repairs and a commissioning phase, and it should reach its full production capacity in the first fifteen days of August 2006, and in July it already produced 76% of its capacity.

25. EMPLOYEES’ PENSION FUND

(i) Private Pension Administration

The Company is the principal sponsor of the CSN employees’ pension fund ("Caixa Beneficente dos Empregados da CSN” - CBS), a private non-profit pension fund established in July 1960, main purpose of which is to pay supplementary benefits to those of the official Pension Plan. CBS congregates CSN employees, of CSN related companies and the entity itself, provided they sign the adherence agreement.

(ii) Characteristics of the plans

CBS has three benefit plans, as follows:

35% of average salary plan

It is a defined benefit plan (BD), which began on February 1, 1966, for the purpose of paying retirements (related to length of service, special, disability or old age) on a life-long basis, equivalent to 35% of the participant’s salaries for the 12 last salaries. The plan also guarantees the payment of sickness assistance to the licensed by the Official Pension Plan and it also guarantees the payment of funeral grant and pension. The participants (active and retired) and the sponsors make thirteen contributions per year, being the same number of benefits paid. This plan became inactive on October 31, 1977, when the new benefit plan began, and it is in process of extinction.

Supplementary average salary plan

It is a defined benefit plan (BD), which began on November 1, 1977. The purpose of this plan is to complement the difference between the 12 last average salaries and the Official Pension Plan (Previdência Oficial) benefit, to the retired, and also on a life-long basis. As with the 35% Average Salary Plan, there is sickness assistance, funeral grant and pension coverage. Thirteen contributions and payment of benefits are made per year. This plan became inactive on December 26, 1995, because of the combined supplementary benefits plan creation.

Combined supplementary benefit plan

Begun on December 27, 1995, it is a combined plan, being a Defined Contribution (CD) related to the retirement and a defined benefit (BD), in relation to other risk benefits (pension in activity, disability and sickness benefit). In this plan, the retirement benefit is calculated based on the sponsor and participants contributions, totaling thirteen per year. Upon retirement of the participant, the plan becomes a defined benefit plan and thirteen benefits are paid per year.

On June 30 and March 31, 2006, the plans are presented as follows:


	6/30/2006	3/31/2006

Members	19,244	18,978

In activity	8,380	8,069
Retired employees	10,864	10,909

Beneficiaries	5,451	5,506

Supplementary average salary plan	1,264	1,246

Total members (beneficiaries)	24,695	24,383

(iii) Actuarial liability

According to the official letter 1555/SPC/GAB/COA, of August 22, 2002, confirmed by official letter 1598/SPC/GAB/COA of August 28, 2002, a proposal was approved for refinancing of reserves to amortize the sponsors’ responsibility in 240 monthly and successive installments, monetarily indexed by INPC + 6% p.a., starting June 28, 2002.

The agreement foresees the installments prepayment in case of cash necessity in the defined benefit plan and the incorporation to the updated debit balance the eventual deficits/surplus under the sponsors’ responsibility, so as to preserve the plans’ balance without exceeding the maximum period of amortization provided for by the agreement.

(iv) Actuarial Liabilities

As provided by CVM Deliberation 371, as of December 13, 2000, approving the NPC 26 of IBRACON – “Employee’s Benefit Accounting” that established new calculation and disclosure

accounting practices, the Company’s management and its external actuaries calculated the assessment of the effects arising from this practice, and records are kept in conformity with the report dated January 10, 2006.

Actuarial Liability Recognition

The Company’s Management decided to recognize the actuarial liability adjustment in the results for the period of five years, from January 1, 2002, being appropriated in the half ended on June 30, 2006, the amount of R$32,315 (R$12,578 in 2005), in accordance with paragraphs 83 and 84 of NPC 26 of IBRACON approved by the CVM Deliberation 371/2000, which, added to related disbursements, totaled R$56,370 in June 2006 (R$39,476 in 2005).

The balance of the provision for coverage of the actuarial liability on June 30, 2006 amounts to R$255,715.

With respect to the recognition of the actuarial liability, the amortizing contribution related to the amount for the participants for determination of the reserve insufficiency was deducted from the present value of total actuarial obligation of the respective plans. A number of participants are disputing in court this amortizing contribution, but the Company, based on its legal and actuarial advisers’ opinion understands that such amortizing contribution was duly approved by the “Secretaria da Previdência Complementar” – SPC and consequently, is legally due by the participants.

In addition, in the case of “Plano Milênio” (Mixed Plan of Supplementary Benefit), of defined contribution, which shows net asset and where the sponsor’s contribution corresponds to an equal counterpart of the participants’ contribution, the understanding of the actuary is that up to 50% of the net actuarial asset may be used for reduction of the sponsor’s contribution. As a result, the sponsor opted for recognizing 50% of such asset on its books, in the amount of R$3,984 in 2006 (R$3,621 in 2005).

Main actuarial assumptions adopted in the actuarial liability calculation

Methodology used	Projected credit unit method
Nominal discount rate for actuarial liability	11.3% p.a. (6% actual and 5% inflation)
Expected yield rate over plan assets	11.3% p.a. (6% actual and 5% inflation)
Estimated salary increase index	INPC + 1% (6.05%)
Estimated benefits increase index	INPC + 0% (5.00%)
Estimated inflation rate in the long-term	INPC + 0% (5.00%)
Biometric table of overall mortality	UP94 with 2 years of aggravation and separated by sex for the BD plans and without aggravation for the CD plan
Biometric table for disability	Winklevoss
Expected turnover rate	2% p.a.
Probability of starting retirement	100% in the first eligibility to a full benefit by the Plan

CSN does not have obligations on other post-employment benefits.

25. SUBSEQUENT EVENTS

• Lusosider

08.01 – COMMENTS ON THE CONSOLIDATED PERFORMANCE IN THE QUARTER

Output

     The low level of crude steel output in the second quarter resulted from the shut-down of Blast Furnace 3 as a result of the accident on January 22. However, the blast furnace 3 recommenced operations on June 23, going through commissioning stage during the month of July, when it reached 76% of its total capacity, and shall reach normal production levels by mid-August, when the recovery and commissioning stage will be over.

     Rolled volume staged a recovery, climbing by 9% over the 1Q06 results, thanks to the use of slabs acquired on the market to partially offset the shortage triggered by the accident.

     In the first half, crude and rolled steel output fell 63% and 27% year-on-year, respectively, once again explained by the above-mentioned incident.

Sales

Although the accident undoubtedly hit sales volume, in comparison to the previous quarter, domestic sales grew by 14% and exports suffered a 37% drop.

In turn, coated products’ share of total sales, was 52% in the second quarter and 55% accumulated year-to-date.

The Company maintained its segment market shares compared to the previous three months. The variation in the Distribution and Construction sectors was only one percentage point each, from 28% to 29% and from 36% to 37%, respectively. The share of home appliances and OEMs remained flat at 33%, as did the Auto industry’s at 13%.

Prices

In the second quarter, average steel prices increased worldwide and remained high throughout, thanks to the continuing imbalance between supply and demand in Europe and the US. Other contributing factors included low distribution and service-center inventories and higher raw-material costs, especially zinc. All in all, we expect the upward price trend to last through the third quarter.

Domestic-market prices are also expected to increase, since demand should remain firm until the end of the year, especially in the auto sector. The industry reached record production levels in May, which pushed up demand for galvanized products. July’s results were equally encouraging and above expectations as the sector experienced its best sales figures since mid-1997, when they reached record levels in Brazil.

CSN’s prices remained flat in the second quarter compared to the previous three months. The slight turndown of 3% on the domestic market was caused by specification variations in each product line, while the 4% upturn in export tags followed the international trend.

In July, CSN implemented prices increases by 8% for hot and cold-rolled and by 12% for galvanized, followed by a 9% hike for tin plate hike in August.

Net Revenue

Although average 2Q06 prices were higher than in the previous three months, the increase was not enough to offset the lower sales volume caused by the problems with the Blast Furnace 3, which explains the 2% quarter-over-quarter slide in net revenue.

Production Costs (parent company)

     As a result of the accidental stoppage, Blast Furnace 3 remained out of operations for almost the entire second quarter, and the consequent purchase of third party slabs at a US$380/t CIF average cost at Sepetiba and US$400/t CIF at Usina is the main factor for the increase of CSN’s total production costs by 33% over the 1Q06. In the year-on-year comparison, there was a 3% decline, since the increase in raw-material costs was more than offset by the decrease in general manufacturing costs (lower materials, supplies and maintenance consumption) Raw-material costs increased by 100% over the 1Q06 and 17% over the 2Q05, due to the higher consumption of slabs acquired from third parties, which jumped from 88,000 tonnes in the 1Q06 to 529,000 in the 2Q06, although this was partially offset by reduced consumption of other raw materials.
     In comparison with the first quarter, the highlights were the increase in the costs of zinc (R$17 million), slab purchases (R$390 million) and labor (R$24 million), the latter influenced by the shift allowance and the pay rise following the 2006/2007collective agreement in May. Compared to the 2Q05, these variations came to +R$22 million, +R$469 million and +R$4 million, respectively.
     As for the main raw materials, the average price of coal dropped from US$138/t, in the 1Q06, to US$136/t in the 2Q06, although this was higher than the 2Q05 average of US$112/t. The average coal and coke inventory cost, totaled US$126/t and US$217/t, respectively, in June. It is worth emphasizing that no acquired coke was consumed in the second quarter.

Other Operating Income (and information on insurance BF 3)

     The main operating income item was record for lost profit. In the second quarter, this record totaled R$493 million, giving R$670 million year-to-date.
     Immediately after the accident in BF 3, to provide arguments for an advance request, FIPECAFI (institution hired by the lead insurer of our insurance policy – Unibanco AIG) estimated, based on extremely conservative assumptions, a compensation of US$330 million related to lost profits only. The insurance claim was recognized by insurers, by IRB (Brazilian Reinsurance Institute) and by foreign reinsurance companies. FIPECAFI and Unibanco AIG recognizes the conservative feature of this preliminary estimate, and as BF 3 resumes operations and financial results of the company are released, the final number will be calculated and the final request for regulation will be made to insurance companies and related insurers. The maximum limit for the compensation policy is of US$750 million, including lost profits and material damages.
     It is worth to mention that up to now, CSN received US$75 million from insurance companies.

EBITDA

Second-quarter EBITDA totaled R$477 million. If we include the provisions for lost profits, the figure came to R$924 million, 2.4% lower than the 1Q06. Year-to-date EBITDA, with the provisions, stood at R$1.9 billion.
It is important to mention that the company has not calculated the adjusted EBITDA margins, since the provision for lost profits was not accounted separately in the respective lines affected by the insurance (Net Revenue and Cost of Goods Sold), but only in Other Operating Expenses. Thus the adjustment would result in a distorted figure.


EBITDA Change (consolidated)	2Q06 x	2Q06 x
EBITDA Change (consolidated)	1Q06	2Q05
EBITDA (ch. %)	-39.5	-60.7
*Adjusted EBITDA (ch. %)	-2.4	-23.9

*EBITDA including the provisions for loss of earnings.

Net Financial Result and Debt

Second-quarter net debt increased by R$1.0 billion quarter-over-quarter, due to R$802 million in dividend and interest on equity payments, period investments of R$485 million and R$173 million in the cost of debt. As a result, the net debt/EBITDA ratio – using 2005 EBTIDA, which was not affected by any non recurring event - climbed from 1.09x in 1Q06 to 1.32x in 2Q06.

In the 2Q06, gross debt increased in both short and long term financing, with special highlight to the 4^thdebenture issue in the amount of R$600 million. The average accumulated cost of debt was 7% p.a. in Brazilian Reais, or 41% of the CDI, and the average maturity was 10.3 years.

Income Taxes

Second quarter income taxes totaled R$118 million, R$102 million less than in the previous three months due to reduced income in the period and lower losses from the exchange variation on the net equity of offshore companies.

Net Income

Net income increased by 20% over the 1Q06, mainly due to the reduction of income tax and social contribution expenses.

Capex

Quarterly investments amounted to R$485 million, R$96 million of which went to projects related to the Casa de Pedra expansion (mine and port), R$162 million to repairs, maintenance and technological updates, R$52 million to MRS, and R$105 million related to Metalúrgica Prada acquisition. Year-to-date investments totaled R$735 million.

Working Capital

Working capital increased by R$100 million, quarter over quarter, mainly due to the increase in inventories (slab acquisitions), partially offset by the reduction in accounts receivable and the increase in suppliers line (also due to slab acquisitions).

Capital Markets

CSN’s shares appreciated by 7% in the second quarter, following the 43% appreciation in the first three months. This appreciation occurred despite the unfavorable international scenario, with interest rate hikes in the US and Europe offsetting the positive developments in the steel market, with strong demand, high prices and several mergers and acquisitions.
