10.01 - MANAGEMENT REPORT

1. MESSAGE FROM THE CHAIRMAN

The year of 2006 was marked by a series of momentous challenges and once again CSN demonstrated its extraordinary resilience, overcoming adversities with enthusiasm, determination and transparency.

The year began with the impact of accident to Blast Furnace 3 in Volta Redonda, which accounts for more than 70% of our steel production capacity. Nevertheless, we still managed to record exceptionally healthy operating and financial results.

We took immediate steps to ensure that our clients did not suffer any product delivery problems by importing slabs from third parties. Although this had an adverse impact on our costs, given that our own slabs are the most cost-competitive in the world.

Even in such a challenging scenario, CSN’s crude steel production still reached 3.5 million tones. We also consolidated our domestic-market leadership in the higher added-value coated steel segment.

We posted an annual net income of R1.168 billion and cash flow, measured by EBITDA, of R$3.82 billion. The EBITDA margin, adjusted for the receipt of lost earnings, stood at 42.3%, ensuring that we retained our position as the world’s most profitable integrated steelmaker.

We were also the Brazilian Company that paid the most, in terms of dividends per share, to its shareholders in 2006, distributing more than R$2 billion in dividends and interest on equity.

We invested around R$1.5 billion last year in expanding iron ore output at the Casa de Pedra mine in Minas Gerais, in enlarging the port of Itaguaí, in Rio de Janeiro, in MRS and in maintenance of the Compamy’s plants.

The offers we have made to acquire strategic assets in Europe and the US are also part of this strategy. The idea is to increase slab production in Brazil, at extremely attractive costs. Output will then be exported to CSN companies in these regions, where they will be rolled, transformed into high added-value steel products of exemplary quality and sold. As result, we expect to generate substantially higher returns than those of our future competitors in these exceptionally important markets.

The construction of our new cement plant is also moving ahead as planned; all the necessary equipment has been ordered and we expect to be offering the Brazilian construction industry yet another product guaranteed by the CSN seal of quality. I

The long steel project is underway in Volta Redonda (RJ), with conclusion expected for 2008.

CSN’s share closed 2006 with an annual appreciation of 45%, as compared to 33% rise of the Ibovespa. The outlook for 2007 is very favorable since the very first quarter.

Our investors are well aware that the present time is one of solid results, they are even more confident regarding the Company’s future and CSN will do everything possible to ensure they are not disappointed.

BENJAMIN STEINBRUCH
Chairman of the Board of Directors

2. THE COMPANY

CSN is a highly integrated company whose carbon steel operations cover the entire production chain, from the mining of iron ore to the final delivery of steel slabs, sheets, coils and packaging. It also has interests in railways, port terminals and power generation. Founded in 1941 by the Getúlio Vargas government, it began operations in 1946 as Brazil’s first flat steel producer, paving the way for the implantation of the national automotive sector. Privatized in 1993, it was entirely restructured, becoming one of the world’s most competitive and profitable steelmakers. Currently, it focuses on four key areas: mining, steel, logistics and cement.

This integrated production system, allied to top-quality management, ensures that production costs are among the lowest in the global steel sector. In addition, CSN’s market capitalization at the close of 2006 was among the 15 highest for steelmakers worldwide.

2.1 MINING

The iron ore market remained buoyant throughout 2006. Growing demand, both in Brazil and abroad, especially in China, sent prices up to record heights. As a result, the great challenge facing sector firms at the moment is to ensure sufficient supply capacity to meet their clients’ needs. Output was sold as soon as it was produced and this scenario looks set to continue for some years.

This favorable climate both sustains and strengthens CSN’s strategic plan, which aims to triple iron ore production by the end of the decade. The project will absorb around US$ 1.5 billion and includes the construction of a pelletizing plant and ship loading infrastructure in the port of Itaguaí, in Rio de Janeiro.

Casa de Pedra

With proven reserves of more than 1.6 billion tonnes of iron ore, verified by the international consulting firm, Golder Associates, the Casa de Pedra mine, located in Congonhas, in the state of Minas Gerais, has a current production capacity of 16 million tonnes per year.

Arcos

The Bocaina quarry in Arcos (also in Minas Gerais) has an annual production capacity of 4 million tonnes of limestone and dolomite, which are used as fluxes in the steel reduction process. In 2006, the facility turned out 1.3 million tonnes of these inputs for the blast furnaces in the Volta Redonda steelworks. The quarry will also be supplying non-steel-grade-limestone for the production of clinker, which CSN will use as the raw material for its new cement project, adding yet another activity to boost competitiveness and profitability.

Ersa

Estanho de Rondônia S.A. (ERSA) comprises the Santa Bárbara tin mine in Itapuã do Oeste, and a smelting plant in Ariquemes, both in the state of Rondônia. Output is used in the production of tin-plate at the Presidente Vargas Steelworks.

2.2 STEEL

CSN produces everything from steel slabs to coated items, including galvanized, Galvalume and pre-painted, as well as metallic sheets, all high added-value products less susceptible to

international price swings. The Presidente Vargas Steelworks in Volta Redonda turns out the most complete range of flat steel products in Latin America. In 2008, it will also begin producing long steel using the facilities of the old foundry on the premises of steel plant.

Currently, CSN’s main markets are the automotive, construction, distribution, home appliance, OEM and metal packaging sectors.

The Company has five galvanizing lines in Brazil – three in the Presidente Vargas plant, one in GalvaSud, in Porto Real (in Rio de Janeiro) and one in CSN Paraná, in Araucária (in Paraná), which also produces cold-rolled and pre-painted products. It also has two overseas subsidiaries: CSN LLC, based in Terre Haute, Indiana, USA, which produces cold-rolled and galvanized, and Lusosider, in Paio Pires, Portugal, which also produces coated steel.

CSN is Brazil’s sole producer of tin-plate (and one of the five biggest producers in the world), with an installed capacity of 1.1 million tonnes per year, and Galvalume, a steel coated with zinc and aluminum which combines visual attractiveness with high resistance and is being increasingly used by the construction industry. It also produces pre-painted steel, much in demand by the construction and home-appliance industries, which it delivers in the precise sizes and colors specified by its clients. In 2006, pre-painted output virtually doubled, jumping from 50,000 tonnes, in 2005, to 83,000 tonnes.

The year got off to a bad with January’s accident to Blast Furnace 3 in the Presidente Vargas Steelworks. Despite the hefty impact on crude steel output, however, the Company successfully mobilized its human and financial resources to minimize possible losses for its shareholder, clients and insurers, doing everything possible to ensure continuity of normal operations and prioritizing the domestic market.

Even given this set-back, CSN generated impressive results. Flat steel output totaled 4.1 million tonnes, only 10% less than in 2005, the share of coated products in total sales moved up significantly and the Company consolidated its segment lead. Sales to the distribution, construction and home-appliance sectors did best.

Achieving such a positive annual performance was no easy task, however. No less than 4,000 people were hired specifically to undertake the repairs to Blast Furnace 3. Aside from the material damage, the accident jeopardized slab production and led to substantial loss of earnings. The Company spent around US$ 90 million (R$ 193 million) alone on the equipment and services associated with the repairs, which proved entirely successful.

The work lasted for close to five months, a very short period of time and considered a record by the market. The blast furnace returned to operations in June and gradually climbed back to normal production levels throughout the second half.

Due to the shutdown, CSN was forced to acquire 1 million tonnes of slabs from third parties, mostly based abroad, to keep its rolling mills supplied and avoid disappointing its clients.

The financial, commercial, legal affairs and supply areas worked in complete unison and demonstrated considerable negotiating skills. The slabs wee acquired at a fair price, minimizing the final cost and, consequently, the impact on margins. A great deal of effort was also expended on finding suppliers with the requisite high quality standards.

These purchases also involved considerable exertion on the logistics front involving reception of the slabs in Brazil and their subsequent transport to Volta Redonda, not to mention the

reprogramming of the steelworks itself, a highly complex undertaking from the technical point of view. Below we present the performance of CSN’s subsidiaries:

Metalic Nordeste

Metalic is the only manufacturer of two-piece steel cans for carbonated beverages in Latin America. In 2006, the company, which also produces aluminum lids, sold 760 million cans and 1,216 million lids, 18% up on the previous year. It retains a 7% share of the Brazilian beverage can market and 45% of the Northeast market.

In 2007, Metalic plans to expand production capacity to 1 billion cans per year and has been conducting feasibility studies into opening a new plant nearer to the country’s main consumption region, the Southeast.

Prada

In 2006, through its subsidiary Inal, CSN acquired Prada, Brazil’s leading manufacturer of steel packaging for the chemical and food industries, with production units in São Paulo, Araçatuba and Uberlândia. The acquisition is currently in the process of being approved by Cade (the government’s antitrust authority).

In the second half, Prada was subjected to a thorough organizational overhaul, which involved streamlining costs and personnel, reorganizing productive processes and providing integrated solutions for clients.

Inal

CSN operates in the steel distribution and service market through Indústria Nacional de Aços Laminados S.A. (Inal), which maintains a presence in six Brazilian states. The leader in the flat steel distribution segment, it supplies various sectors, including the automotive, auto parts, home appliance, construction, electromechanical machinery and equipment, packaging and furniture industries, as well as resales, all of which under the just-in-time system.

In 2006, it distributed 343,300 tonnes of steel, 8.1% more than in 2005, a new company record.

GalvaSud

GalvaSud S.A. is strategically located between Rio de Janeiro and São Paulo and offers a wide range of world-class products and services. It has galvanizing and shearing lines, as well as a state-of-the-art laser welding facility, and its main customer is the automotive industry. In 2006, it produced 273,000 tonnes, versus 247,700 tonnes the year before.

CSN LLC

CSN LLC, the Company’s Indiana-based US branch, played an important role during the shutdown of Blast Furnace 3 at the Presidente Vargas Steelworks, buying most of the 1 million slabs that CSN had to acquire from third parties. The company operates a cold-rolling mill and a galvanizing line. In 2006, it imported 303,476 tonnes of steel slabs and coils from Brazil for processing and sale in the American market.

Another important event was the slab-supply agreement with Wheeling-Pittsburgh which is valid throughout 2007. Slabs are the raw material for hot-rolled coils.

Lusosider

In mid-2006, CSN acquired the 50% stake in Lucosider retained by the Anglo-Dutch Corus for US$ 38 million (R$ 83 million), giving the Company outright control.

Installed in Paio Pires, Portugal, Lucosider achieved its best ever results in 2006, producing 59,000 tonnes of tin-plate and 241,000 tonnes of galvanized, as well as 34,000 tonnes of pickled hot-rolled coils and 25,000 tonnes of cold-rolled coils, totaling 359,000 tonnes in all. Annual revenue stood at US$ 238 million (R$ 518 million).

2.3. LOGISTICS and ENERGY

Ports

CSN manages two terminals in Rio de Janeiro: a Bulk Solids Terminal (Tecar) and a Container Terminal (Sepetiba Tecon), both in the port of Itaguaí (formerly Sepetiba). Tecar is currently being expanded to begin iron ore exports in the first quarter of 2007, with an initial capacity of 7 million tonnes per year.

The works will continue throughout 2007 and the concluding phase will take place in 2008, by which time Tecar will have a shipping capacity of 30 million tonnes per year, consolidating Itaguaí as one of Brazil’s largest port complexes.

In 2006, Tecar handled 2.44 million tonnes of products, including coal, coke, sulphur, zinc concentrate, pellets, pig iron, ferroalloys, soybean and other bulk solids on behalf of CSN and various clients. This volume was 42.02% less than in 2005.

Sepetiba Tecon handled 190,600 containers, versus 138,000 in the previous year, and 1.67 million tonnes of steel products, 72% up on 2005. Strong demand in this market, which has been recording substantial annual growth recently, has made the terminal one of the biggest in its segment.

Railways

CSN retains an interest in two railway companies: MRS Logística (32.93%), which operates the former Southeastern Network of the Federal Railways (RFFSA), connecting Rio de Janeiro, São Paulo and Belo Horizonte, and CFN (45.78%), which operates the RFFSA’s former Northeastern Network in the states of Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas.

MRS Logística, which concluded 10 years of operations, continues to grow. In 2006, it carried 113.3 million tonnes, 4.6% up on the year before, and 124,000 TEUs (20-ft containers), consolidating its position as the country’s leading rail container transporter. Gross revenue totaled R$ 2.274 billion, 13.7% more than in 2005 and net income reached the record level of R$ 540.9 million, up by 31.8% .

The main focus was on heavy haul clients (ore, bauxite, coal and coke) and capturing new markets. The company’s services are vital to CSN, both in terms of incoming raw materials and outgoing end products, in that it transports all the iron ore, coal and coke consumed by the Presidente Vargas Steelworks and a good part the steel produced there, both for the domestic and export markets.

In association with the federal government, the Company will invest R$ 4.5 billion in CFN to lay 1,800 kilometers of track, creating the Nova Transnordestina Railway, which will have a transport capacity twenty times greater than at present and will play an important role in the development of Brazil’s Northeast region. Completion is scheduled for 2010.

Energy

CSN is one Brazil’s biggest industrial electric power consumers behind only the aluminum producers. Since 2000, therefore, it has been investing in generation projects in order to ensure self-sufficiency. Its electrical assets are the 1,450 MW Itá Hydroelectric Plant, in Santa Catarina, in which it holds a 29.5% stake; the 210 MW Igarapava Hydroelectric Plant, in Minas Gerais, where it retains a 17.9% interest; and the 238 MW thermoelectric cogeneration plant in the Presidente Vargas steelworks, which is fueled by the waste gases from the steel production process. Together, these three plants give CSN an average generating capacity of 430 MW.

2.4. CEMENT

Not only do the cement and steel industries complement one another, but the cement sector will play an important role in the expansion of the construction industry, which turned over around R$ 25 billion in 2006. The country’s housing deficit is estimated at 7.2 million units, a clear indication of huge potential growth, fueled by the increasing availability of public and private credit. The Presidente Vargas Steelworks produces around 1.4 million tonnes of blast-furnace slag every year, sufficient to supply 70% of the cement plant’s needs.

Consequently, the Company has set up a specific business unit for this market and will begin producing cement on a commercial scale in 2007. Currently half of Brazil’s cement consumption is concentrated in the Southeast region.

3. OUTLOOK, STRATEGY AND INVESTMENTS

With global growth likely to remain high, demand for steel and iron ore should remain buoyant in the coming years. Given this favorable outlook, CSN will seek to use its competitive advantages to expand its businesses in Brazil and abroad, particularly in the EU and US through its existing subsidiaries and new strategic acquisitions. At the same time, it will invest sufficient funds to triple current production capacity, equipping it to take on the new challenges.

The main ongoing projects are increasing iron ore output, raising flat steel production capacity and globalizing operations. There are also two important complementary projects - cement and long steel production.

Iron ore growth

The year of 2007 marks CSN’s first entry into the international iron ore market and it intends to become the world’s fourth biggest iron ore exporter. The first step towards this goal was taken in February, with the completion of the first phase of the expansion of the bulk export terminal in Itaguaí (RJ) and the loading of the first shipment.

CSN aims to penetrate the biggest consuming markets, including Asia, Europe and the Middle East, with its high-grade ore. The second and third phases of CSN’s port expansion are due for completion in November 2007 and July, 2010, respectively. The new pier and conveyor belt will give added flexibility to the unloading of coal and coke and the loading of iron ore, raising handling capacity from 30 million to 53 million tonnes per year.

In 2007, the Company expects to produce 15.5 million tonnes of ore. A total of around US$ 1.5 billion will be spent on the two pelletizing plants and expanding the Casa de Pedra mines. The aim is to triple the Company’s ore area within the next three years, increasing production capacity from the current 16 million per year to 40 million in 2008 and 53 million by 2010.

Investments have already been approved to boost slab capacity from its present level of 5.6 million tonnes per year to 14.6 million. CSN has established a partnership with the Chinese steel group, Baosteel, to draw up a feasibility study and engineering project for a plant in Itaguaí, adjacent to the port, to produce 4.5 million tonnes of slabs per year from three new blast furnaces. Another slab facility of identical capacity may be installed in Rio de Janeiro or Minas Gerais at an as-yet undefined location.

Jointly, the two projects will virtually triple CSN’s current crude steel output, acting as a platform for its global operations. The idea is to produce more slabs in Brazil, shipping the excess abroad for rolling and finishing, thereby becoming a major player in highly sophisticated strategic markets, especially the US and EU, via its existing overseas subsidiaries and new acquisitions to come.

The Company will also invest in the long steel segment, ensuring that it is strategically positioned to take advantage of the expected construction boom in Brazil. It will make use of existing infrastructure in the Presidente Vargas Steelworks and will spend around US$ 113 million on the necessary installations, including expanding and upgrading a 30-tonne electric furnace. The new facility is expected to produce 500,000 tonnes of long steel per year from surplus pig iron and low added-value slabs.

CSN achieved great visibility in 2006 by disputing important assets in Europe and the USA. The offers for the Anglo-Dutch steelmaker Corus and the US-owned Wheeling-Pittsburgh were important steps forward in the Company’s operational globalization process, by means of which it seeks to acquire companies whose activities complement its own and which generate substantial gains in synergy. CSN has been investing in order to play a leading role in the consolidation of the global steel industry.

The offer for Corus, made when the latter firm was already in advanced negotiations with the Indian-owned Tata Steel, took the entire global steel market by surprise. Eventually, the transaction was decided by an auction, which reached US$ 13 billion. Tata won out, bidding 608 pence per share, versus CSN’s 603 pence. The offer for Wheeling-Pittsburgh, although superior to that of its rival, was rejected by the US firm’s Board, which was split by internal issues.

Nevertheless, by taking part in the dispute for these major assets, the Company proved that it has all the necessary qualifications to become a leading global player in the steel sector. It also demonstrated its capacity to raise large sums of capital in short periods of time. CSN remains committed to its globalization strategy, pursuing investment opportunities and gains in scale in order to become even more globally competitive.

As part of this process, the Company created its own commercial network in the USA enabling it to sell directly in that market, without having to rely exclusively upon local traders, while aiming to increase its share of the North American metallic and galvanized sheet segments.

Main Highlights

CSN posted Net Revenue of R$ 2.58 billion in the 4Q06, registering R$ 5.17 billion for the second half, up by 7% and 12% year-on-year, respectively. Annual net revenue exceeded R$ 9 billion.

Annual EBITDA, adjusted for earnings losses due to business interruption, came to R$ 3.82 billion (approximately US$ 1.8 billion) accompanied by an EBITDA margin, similarly adjusted, of 42.3%, climbing back to end-of-2005 levels.

Annual Net Income totaled approximately R$1.2 billion.

These results are particularly important, given the accident to the structure adjacent to the main blast furnace (BF-3) on January 22, 2006, which is responsible for 70% of the Company’s steel output. CSN demonstrated exceptional operational resilience, taking immediate steps to acquire appropriate volumes of steel slabs in order to avoid any break in production and ensure delivery of end products to clients. At the same time, it immediately activated its pool of insurers, in order to guarantee compensation as quickly as possible, both for material damages and lost earnings, through the insurance policies duly taken out to cover just such a contingency.

BF-3 returned to full capacity in the second half of the year. Although costs were significantly affected, especially due to the purchase of slabs from third parties, the Company’s results and margins underlined its ability to recover, even in such a challenging scenario as that of 2006.

The Company’s average sales prices for the year were very close to 2005 levels (-3%). Average prices in the 4Q06 were 2% and 29% up on the domestic and export markets, respectively.

As of November 2006, CSN was one of the bidders in the acquisition of the UK-based Corus Group, whose auction was completed in the 1Q07, aiming throughout this process to ensure the best rates of return for all its shareholders. Management did everything possible to emerge victorious, but without exceeding the pre-established debt and investment limits considered appropriate for the Company’s future. In 2007, the Company will sell its minority 3.8% stake in Corus.

ECONOMIC AND STEEL SCENARIO

Domestic Market:

Brazil’s GDP recorded growth of 2.9% in 2006, less than the global average of 5.1% and also lower than the 6.5% average registered by the emerging countries.

The Brazilian flat steel market did exceptionally well in the 4Q06, with a 26.9% increase in sales volume over the same period the year before, mainly fueled by higher consumption in the Distribution and Construction sectors. The construction industry recorded growth of 54.3% and 10.2% over the 4Q05 and 3Q06, respectively.

In 2006 as a whole, Brazil’s flat steel sales moved up 7.3% over the previous year, led by the Automotive, Distribution, Home Appliance and OEM segments.

International Market:

On the international front, the impact of economic growth in China and India, which once again recorded significant increases in production, affected, above all, the global steel market. In addition, the international steel market continued with its consolidation process, with expansion projects concentrated in the low-cost production regions, notably in the “BRIC” nations (Brazil, India, Russia and China).

The year was also marked by exceptionally volatile prices for metals with a direct effect on steel prices.

Following a year of adjustments between supply and demand, which included localized production cut-backs, international steel product prices were subject to swings, peaking in mid-July, 2006. As of then, there was a series of gradual reductions, partially due to increased global output and partly to high inventories in certain consuming markets, such as the US.

The outlook for 2007 is still positive, given that the European and American markets have already demonstrated concerns over excess exports of Chinese products, with manifestations of possible control and protection measures. In addition, inventories may fall at a more accelerated pace in the 1Q07, opening the way for a new round of price increases, which may well become a global trend.

PRODUCTION

In 2006, as a direct result of the accident to BF-3, annual crude and rolled steel production fell by 32.7% and 8.95%, respectively. The acquisition of slabs on the market offset the lower output of crude steel, ensuring proportionally higher deliveries of rolled products to clients. With the return to operations of BF-3, crude steel production in the 4Q06 was already back in line with 4Q05 levels.

PRODUCTION COSTS (PARENT COMPANY)

In the 4Q06, total production cost was R$ 1.3 billion, R$ 115 million (+9%) higher than the total production cost recorded in the 4Q05. This increase was basically due to the consumption of slabs and coils acquired from third parties, whose total period cost was R$ 93 million.

Annual production costs totaled R$ 4.8 billion, in line with the 2005 figure. There were, however, opposing factors among various lines, which ended up canceling each other out:

Cost increases

Increase of R$ 0.9 billion, from the consumption of slabs and coils acquired from third parties, and R$100 million from the upturn in international zinc prices;

Cost reductions

Reduction of R$ 472 million, due to lower coke prices and coke consumption. The cost of coke fell by more than 50% and the drop in consumption can be explained by the reduced output from BF-3.

Reduced consumption of other raw materials, such as coal (R$ 171 million), iron ore (R$ 30 million), tin (R$ 28 million), scrap metal (R$ 36 million) and others (R$ 28 million);

Finally, general manufacturing costs fell by around R$180 million, also associated with January’s accident; notably around R$ 90 million in electric power and fuel costs, and R$ 90 million in other expenses (maintenance and others).

SALES

Total Sales Volume

Annual sales volume totaled 4.384 billion tonnes, 10% down on 2005.

Domestic Market

Domestic sales volume of 732 thousand tonnes in the 4Q06 fell 8% over the previous three months, primarily due to the lower number of business days in December. In year-on-year terms, however, the result was highly positive, with a 22% increase over the 4Q05.

Annual domestic sales volume (2.818 billion tonnes) remained in line with the previous year, justifying the Company’s strategy of prioritizing the Brazilian market in 2006, given the above-mentioned restrictions on production occasioned by the fact that the Company’s main blast furnace was inoperative throughout the first half.

Export Market

Exports of 462 thousand tonnes in 4Q06 remained stable over the previous quarter. However, in comparison with the 4Q05, they fell by a substantial 39%, due to the heating up of the domestic market and the Company’s strategy mentioned above. For the same reasons, annual export volume of 1.568 billion tonnes fell 21% over 2005.

Market Share and Product Mix

In the 4Q06, the Company recorded a 28% share of the domestic flat steel market (hot-rolled, cold-rolled and galvanized), very close to the 30% recorded in the previous quarter and an improvement over the 4Q05 figure of 24%.

For the year as a whole, it recorded an average market share of 27%, stable in comparison with the previous year.

As for the product mix, the Company once again exceeded a 53% market share of the coated products domestic market, the same level as in 2005.

NET REVENUE

The improvement in CSN’s 4Q06 domestic and export prices over the previous quarter offset the reduction in national sales volume, leading to revenue of R$ 2.576 billion. In year-on-year terms, net revenue moved up 7%.

Annual net revenue was R$ 6.4 billion in Brazil and R$ 2.6 billion abroad. Both markets recorded a reduction – 7% and 16%, respectively, due to the volume and price trends described previously (production cut-backs and a focus on the domestic market) associated with the price tendency in place over the last two years.

OTHER OPERATING REVENUE AND EXPENSES

The major highlight in other operating revenue and expenses was the booking of R$ 730 million (US$ 334 million) for earnings losses due to business interruption in the “Other Revenue” line. The upper indemnity limit of the policy is US$750 million, including the earnings losses and material damages.

In 2006 and January 2007, CSN received R$ 515 million (US$ 237 million) in advances from the insurers.

When compared to 2005, the impact was reduced by non-recurrent reversals booked in 2005.

EBITDA

Fourth-quarter EBITDA moved up by 8% over the previous three months, from R$ 912 million to R$ 984 million and the EBIDA margin widened by 3 percentage points, fueled by the return to operations of BF-3. It is worth pointing out, however, that the 4Q06 margin of 38% reflects operating costs that were still affected by the accident, especially the higher inventory costs of steel produced in previous months and acquired from third parties. 2006 Annual EBITDA totaled

R$3.16 billion and EBITDA margin was 35%.

Adjusted EBITDA totaled R$3.82 billion, accompanied by an EBITDA margin of 42.3%, reflecting management’s success in minimizing the impact of the BF-3 accident and the Company’s return to normal operations.

COMMENTS ON EBITDA

EBITDA represents net income (loss) before the financial result, income and social contribution taxes, depreciation and amortization. EBITDA should not be regarded as an alternative to net income (loss) as an indicator of CSN’s operating performance or as an alternative to cash flow as an indicator of liquidity. Although CSN’s management considers EBITDA to be a practical means of measuring operating performance and permitting comparisons with other companies, it is not recognized by Brazilian Accounting Principles (Brazilian Corporate Law or BR GAAP) or US Accounting Principles (US GAAP) and other companies may define and calculate it differently.

NET FINANCIAL RESULT AND DEBT

The 4Q06 financial result was a net expense of R$ 255 million, R$ 150 million less than the expense recorded in 4Q05 and R$ 182 million less than the expense booked in the 3Q06.

With the fall in the US dollar x Brazilian Real exchange rate, the net monetary and exchange variation line recorded revenue of R$ 136 million, an improvement of R$ 460 million and R$ 146 million, respectively, over the expenses recorded in the same two prior periods.

The appreciation of the Real against the dollar had a negative impact on the financial revenue line, which recorded a negative R$ 18 million, or a negative variation of R$ 289 million and a positive one of R$ 6 million when compared to the 4Q05 and 3Q06, respectively. The Company’s strategy is to neutralize the impact of variations in the exchange rate on its results through foreign exchange hedge instruments, which are booked in the financial revenue line.

Finally, 4Q06 financial expenses, basically comprising interest on the debt and the restatement of contingent liabilities, totaled R$ 372 million, R$22 million down on the 4Q05 and R$22 million up on the 3Q06.

The Company recorded an annual net financial expense of R$ 900 million, versus an expense of R$ 761 million in 2005. Given the damage to BF-3’s peripheral/auxiliary equipment and its impact on cash flow, the net debt averaged R$ 5.6 billion in 2006, versus R$ 4.5 billion in the previous year. Up to the date of writing, the insurance companies have advanced US$ 237 million.

The financial cost of the debt, in Brazilian Reais, remained at 11% p.a., equivalent to 73% of the CDI CETIP rate, versus 14% p.a. in 2005, also equivalent to 73% of the CDI. The progressive reduction in the basic SELIC interest rate has partially offset the increase in the Company’s net debt.

At the close of 2006, CSN’s net debt totaled R$ 6.7 billion, R$ 1.95 billion above the end-of-2005 figure. Apart from the impact of the BF-3 accident on annual operating cash flow, there were certain additional reasons for the increase, notably the investments of more than R$ 1 billion, dividend payments of R$ 2.1 billion and R$ 0.7 billion disbursed at the end of the year to acquire 34,072,613 shares in the Corus Group (UK), equivalent to 3.8% of the company’s capital, booked under “other investments”. When adjusted to reflect the future sale of these shares at 608 UK pence each, as approved by the Shareholders’ Meeting of March 7, 2007, net debt is reduced by around R$ 0.9 billion, to R$ 5.8 billion.

The net debt/EBITDA ratio stood at 1.7x in 2006, or 1.5x when adjusted for the sale of the stake in Corus. Taking EBITDA in 2005, when the Company was operating normally, as the ratio base, the ratio would be reduced to 1.25x.

At the close of 2006, consolidated gross debt totaled R$ 9.4 billion, or R$ 0.6 billion higher than at the end of December 2005. In May 2006, CSN effected its 4th issue of non-convertible debentures in the amount of R$ 600 million, maturing in February 2012. Subsequently, in November and December, the Company raised a further US$ 700 million: US$ 200 million in ACCs (Advances on Export Contracts), US$ 100 million in pre-payments, US$ 100 million in Import Notes (effected through its subsidiary CSN Steel and maturing in December 2011), and US$ 300 million, through a previous contracted credit line (Revolving Credit Facility).

Also in December of 2006, the Company redeemed R$ 650 million in debentures, R$ 400 million of which from the 2nd. issue and R$ 250 million from the first series of the 3rd.issue.

On December 31, 2006, the average maturity of the gross debt was 7.4 years.

COMMENTS ON NET DEBT

Net debt as presented is used by CSN to measure our financial performance. However, net debt is not recognized as a measurement of financial performance according to the accounting practices adopted in Brazil, nor should it be considered in isolation, or as an alternative to net income or financial result as an indicator of liquidity. Other companies may calculate net debt differently

INCOME TAXES

Annual income and social contribution taxes were R$350 million lower than in 2005, primarily due to reduced taxable income, explained by the variations dealt with above. The effective 2006 tax rate was 31%, versus 30% in 2005.

NET INCOME

Net income totaled R$ 83 million in the 4Q06, annual net income came to R$ 1.168 billion in 2006, with a net margin of 13%.

The 42% reduction over 2005 was mainly due to the impact of the BF-3 accident on gross profit, partially offset by the booking of provisions for earnings losses due to business interruption.

CAPEX

Investments totaled R$380 million in the 4Q06, R$147 million of which went to the Casa de Pedra iron ore mine expansion project, R$24 million to the Sepetiba port expansion project, R$63 million to the MRS railway system (corresponding to CSN’s 33% stake in the company) and R$34 million to industrial maintenance.

Investments in 2006 totaled R$ 1.5 billion, as follows: R$247 million in the Casa de Pedra mine expansion; R$176 million in the Sepetiba port expansion project; R$175 million in MRS; R$ 78 million in Lusosider, in Portugal; R$ 122 million in the subsidiary Prada; and R$ 396 million in general maintenance projects. Most of the remainder went to smaller, but also relevant, projects associated with maintenance and overall improvements in CSN’s operating performance and that of its subsidiaries.

Ore Export Terminal

In February, 2007, CSN completed the first phase of the expansion of its Iron Ore Terminal in the port of Itaguaí, with an initial annual export capacity of 7 million tonnes. The second phase will raise the terminal’s capacity to 30 million tonnes p.a., and the third to 53 million tonnes p.a. Investments are estimated at US$ 260 million, until the conclusion of the works and the installation of the necessary equipment.

WORKING CAPITAL

At the close of 2006, working capital invested totaled R$ 1.9 billion, 7% and 6% higher, respectively, than at the end of September 2006 and December 2005. It is important to note that, due to the profile of coke and coal imports (one-off, large-scale purchases), the raw material inventories, suppliers and advances to supplier lines may show some oscillations, although without any significant change in working capital management. In the periods in question, these accounts, if analyzed jointly, showed no significant variation.

The balance of warehoused materials may also show some oscillations, caused by investments or important maintenance procedures involving major items of equipment, which occur on a one-off, unscheduled basis over time.

The average supplier payment period remained at around 90 days, while client payment periods averaged around 40 days. Accounts receivable at year-end were around R$ 74 million less than in December 2005 due to the different amounts billed in the final months of each year.

Finally, it is worth highlighting the annual difference of almost R$ 166 million in the taxes payable line, which was primarily due to the greater concentration of sales in the domestic market and the consequent increment in the amount paid in local sales taxes.

4. CORPORATE GOVERNANCE

Investor Relations

As of August 2006, the Investor Relations area became a Department reporting directly to the CEO. CSN took part in several national and international market events and completed the redesign and upgrading of its IR web pages as part of its general website overhaul. The Company also became affiliated to the INI (National Institute of Investors) in order to form closer ties with individual investors.

CSN’s disclosure procedures were classified among the five best in Latin America, according to the technical criteria of the 9th edition of the Investor Relations Global Rankings, held in February 2007, in which 145 companies from 33 countries participated.

The awards were organized by MZ Consult Serviços e Negócios and the independent judging committee comprised representatives from Linklaters, IR Magazine and KPMG International.

Sarbanes-Oxley Act

We are in the final certification stage for our internal controls related to financial statements, in compliance with Section 404 of the Sarbanes-Oxley Act. In 2006, tests were carried out to verify the effectiveness of the internal controls of CSN, CSN Export, Inal and Fundos de Investimentos Exclusivos as part of the certification process that began in July of the same year. A total of 1927 controls and 52 processes were mapped. All the controls were tested by management and 859 were verified by internal audit (611 via monitoring and 248 via walkthrough).

Code of Ethics

CSN has employed a Code of Ethics since 1998, which is periodically revised and updated. In 2006, Board members, executives and employees of all the CSN Companies received yet another revised version and signed the respective consent agreement. New versions are delivered to members of staff by their superiors in meetings where the changes can be discussed and any possible queries cleared up.

CSN’s Code of Ethics not only details the standards of personal and professional conduct expected of its employees in their relations with their various constituencies, but also contains a declaration of our corporate conduct and commitments.

One constant aspect of the Code since 1998 is the guidance on trading in the Company’s shares.

Disclosure of Material Facts

CSN maintains a Material Fact Disclosure Policy, which determines that all such disclosures must contain information that is accurate, consistent, appropriate, transparent and within the

proper deadlines, in accordance with CVM Instruction 358 of January 3, 2002, and Section 409 of the Sarbanes-Oxley Act – Real Time Issuer Disclosure.

All material facts are disclosed to the markets in which the Company’s shares are listed, currently Brazil (BOVESPA) and the United States (NYSE).

Administration

CSN is controlled by Vicunha Siderurgia S.A., which holds a 43% interest, and administered by its Board of Directors and Board of Executive Officers. In compliance with the prevailing legislation, the General Shareholders’ Meeting, the Company’s governing body, meets once a year, or whenever necessary, to discuss and approve matters in the Company’s interest.

The role of the Board of Directors is to analyze and approve overall policies and strategies and oversee the activities of the Board of Executive Officers. It is also responsible for appointing these Officers and the members of the statutory committees.

Board of Directors

The Board of Directors Comprises eight members and meets ordinarily on the dates set forth in the annual schedule of corporate events.

Audit Committee

The Audit Committee has the autonomy to take decisions related to the provisions of the Sections 301 and 407 of the Sarbanes-Oxley Act. Its main responsibilities are to review, consider and recommend to the Board of Directors the appointment, remuneration and hiring of the external auditors, as well as supervising the internal and external audits.

Internal Audit

CSN employs the services of an independent Internal Audit, as determined in the Bylaws. Using generally accepted auditing principles, it tests, analyses, maps and corroborates the internal controls of all the CSN Companies in order to assess their effectiveness, appropriateness and integrity, as well as their cost-effectiveness. The work of the Internal Audit is defined according to the Risk Matrix and approved by the Audit Committee, which also monitors its results.

Independent Auditors

In 2006, CSN and its subsidiaries’ independent auditors – Deloitte Touche Tomatsu Auditores Independentes – were hired to perform services in addition to those related to the examination of the financial statements.

Both the Company and its independent auditors recognize that these services, essentially comprising reviews of income tax declarations, do not affect the auditors’ independence. Payment for the services in question did not exceed 5% of the total external auditing fees.

Certain services to be provided by the external auditors, in addition to examining the financial statements, are previously submitted to the legal affairs department and the Audit Committee in order to ensure that they do not involve a conflict of interest or jeopardize the auditors’ independence or objectivity.

5. RISK MANAGEMENT

CSN has a fully comprehensive insurance policy designed to meet its specific needs. Due to its high degree of complexity, this policy is backed by ample coverage with the IRB-Brasil Re (Brazilian Reinsurance Institute) and international reinsurers. Shortly after the accident to Blast Furnace 3 in the Presidente Vargas Steelworks, CSN assessed the resulting damages at US$ 600 million, US$ 100 million of which in material damages and the remainder in lost earnings, and duly communicated this estimate to the lead insurer, Unibanco AIG.

Until the date of writing, CSN has received US$ 237 million and expects to receive the remainder by the end of the first half of 2007. The reinsurers involved have already booked provisions for this payment in their financial statements.

6. INNOVATION

One of CSN’s primary strategies is to meet clients’ needs in a creative way in order to provide them with products and services of the highest quality. It therefore makes a point of investing in innovative solutions in all its operational areas.

Research and Development

As Brazil’s leading producer of high added-value coated flat steel products, CSN has invested continuously in improving its products, processes and services.

In 2006, R&D absorbed investments of R$ 40.2 million, with a particular focus on new products and processes, and the latter’s application in the production chain. in order to ensure improved performance and customer service and ensure that the Company continues to provide its clients with innovative solutions.

As a company that leads from the front, CSN is fully committed to seeking out pioneering technology, generating products that are welcomed by the market and continuously upgrading its production procedures.

7. HUMAN RESOURCES

In 2006, CSN stepped up its efforts to align its subsidiaries’ human resources policies in order to establish standardized criteria for behavior and evaluating individual performance and results.

Throughout the year, the Company adopted a number of measures, including the mapping and redefining of job and salary structures, linking these to the results that each position generates for the Company.

CSN recognizes that, in order to achieve its goal of tripling in size within three years, it must adopt a pro-active approach to attracting, developing and retaining the best talent available. Technical competence, the necessary flexibility to cope with constant change and a focus on results are the chief attributes the Company looks for in its employees, whose conduct must be governed at all times by the highest ethical and professional standards. CSN and its subsidiaries closed 2006 with 13,640 employees, versus 12,396 at the end of 2005.

Internal Communications

CSN invests in the best corporate communications procedures, employing a variety of channels to communicate with its staff, including printed and electronic bulletins, a bimonthly magazine, a

notice-board newspaper, banners, billboard posters, an intranet and an e-mail system with specific addresses for media relations, the internal auditors and the ethics committee.

In 2006, the Company upgraded its intranet and the CSN portal, bringing them into line with the best practices employed by major corporations worldwide, facilitating browsing, increasing interactivity and providing more and better information, thereby benefiting staff, clients and other users.

Involving staff in management

In 2006, CSN employed two initiatives designed to increase staff involvement in management: the Quality Cycle and the Technological Seminar. The latter allows employees make technical contributions designed to improve systems and help the Company’s growth. Both projects award prizes for the best contributions, based on criteria such as profitability, productivity gains and cost reductions.

Training and development

CSN offers its staff with a number of training and development opportunities. One such example is Programa Educar, which was first set up in 1998 in the Presidente Vargas Steelworks. It provides primary and secondary level school education, as well as technical training, and has already benefited more than 2,394 employees. The program is fully funded by the Company, which also provides the classrooms, organizes the courses and the teachers and maintains agreements with several educational institutions.

Every year, CSN employees can also take advantage of the courses in Electromechanics and Metallurgy, which are co-sponsored by the Fundação CSN’s Escola Técnica Pandiá Calógeras. Participants have invariably joined the internal recruitment program and been promoted to technical positions.

The Company also grants partial university study scholarships as a means of furthering the professional and personal development of its staff.

Profit sharing

The Profit Sharing Program is tied to corporate earnings. All areas have pre-established targets which must be met during the year. The amount payable is calculated according to the average fulfillment of these targets on a Company-wide basis.

Work safety

CSN puts considerable emphasis on safety in the workplace. Accident prevention programs, which are extended to cover subcontracted employees, are progressive in nature, with a focus on developing a safety-first attitude. There are weekly meetings to analyze corrective and preventive measures.

8. SOCIAL RESPONSIBILITY

Since its earliest days, CSN has been developing socially responsible policies, an activity which is currently handled by the Fundação CSN. The Company is deeply committed to its neighboring communities and to the country’s social and economic development, sponsoring projects in a wide range of areas including education, community development, health, sport and the arts. In 2006, it invested R$13 million in social projects, benefiting more than 400,000

people in 12 municipalities in five states, always in association with carefully selected institutions.

The Fundação CSN also develops community projects geared towards generating income in underprivileged areas in Volta Redonda and Itaguaí (RJ), Congonhas and Arcos (MG), Mogi das Cruzes (SP) and Araucária (PR). Moreover, it sponsors digital and social inclusion programs through the Projeto Informática e Cidadania (Information Technology and Citizenship Program), developed in partnership with the CDI (Information Technology Democratization Committee), which aims to prepare underprivileged youngsters and adults for the job market.

9. ENVIRONMENTAL RESPONSIBILITY

Promoting a socially responsible approach to the environment is part of CSN’s daily routine. In addition to prioritizing state-of-the-art risk management and monitoring equipment, the Company has an Internal Environmental Management Committee, made up of members from all areas of the main plant. It meets once a week to discuss any problems that may arise and identify potential trouble spots, in order to take preventive action and minimize any possible environmental impact.

The Company has also implanted an Environmental Management System in its operational units, designed to effect continuous improvements to its environmental performance. Based on the international ISO 14001:2004 norms, it is applied in an integrated manner throughout the Company’s various production chains. Its industrial operations in Volta Redonda and Porto Real (RJ), and Congonhas and Arcos (MG), have received this certification, and are audited every year by renowned certification firms. In 2006, CSN spent R$ 224 million on environmental projects (initial and ongoing).

10. FORWARD-LOOKING STATEMENTS

Certain of the statements contained herein are forward-looking statements, which express or imply results, performance or events that are expected in the future.

The Financial Statements prepared in US dollars, in Euros and in Great Britain Pounds were translated to Brazilian currency at the exchange rate as of December 31, 2006 – R$/US$2.138 (R$/US$2.3407 in 2005), R$/EUR2.82024 (R$/EUR2.76905 in 2005) and R$GBP4.18535 (R$/GBP4.02202 in 2005).

The gains and losses from this translation were recorded 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.

14. DERIVATIVES AND FINANCIAL INSTRUMENTS

General considerations

The Company’s business includes mainly the production of flat steel to supply the domestic and foreign markets and mining of iron ore, limestone, dolomite and tin to supply the Presidente Vargas Steelworks’ needs. To finance its activities, the Company often resorts to the capital market, local as well as international, and, due to the debt profile it seeks, most of the Company’s debt is pegged to the dollar. On December 31, 2006, the consolidated position of the outstanding derivative agreements is as follows:


	Agreement			Market Value

	Maturity	Reference Value	Book Value


Variable income swap ()*	Jul 27/2007	US$49,223 thousand	R$490,003	R$490,003

	Jul 2/2007	thousand	(R$6,825)	(R$6,825)

(*) The non-cash swap establishes that the counterparty undertakes to pay, at the end of the contract, the variation of variable income assets, as long as the Company’s subsidiary, CSN Steel, undertakes to pay the same reference value adjusted at the fixed rate of 7.5% per annum. This amount is shown in the Marketable Securities account under current assets.

The main market risk factors that can affect the Company’s business are listed below, as well as a more detailed explanation about the derivatives associated with them:

I - Exchange risk

Although most of the Company’s revenues are denominated in Brazilian reais as of December 31, 2006, R$7,654,471 or 81% of the Company’s consolidated loans and financing (except for derivates) were denominated in foreign currency (R$6,962,797 or 79% in 2005). As a result, the Company is subject to fluctuations in exchange and interest rates and manages the risk of the fluctuations in the amounts in Brazilian reais that will be necessary to pay the obligations in foreign currency, using several financial instruments, including dollar investments and derivatives, mainly futures contracts, swaps contracts, currency contracts and option exchange contracts.

II - Credit risk

The credit risk exposure with financial instruments is managed through restrictions of counterpart to large financial institutions with high quality of credit. Thus, Management believes that the risk of non-compliance by the counterpart is insignificant. The Company neither maintains nor issues financial instruments for commercial purposes. The selection of customers, as well as the diversification of its accounts receivable and the control on sales financing conditions through business segment are procedures adopted by CSN to minimize occasional problems with its customers. Since part of the Companies’ funds are invested in Brazilian government securities, there is exposure to the credit risk with the government.

III - Fair value

The fair values were calculated according to the conditions in the local and foreign markets as of December 31, 2006, for financial transactions with identical features, such as: volume and term of the transaction and maturity dates. All transactions carried out in non-organized

markets (over-the-counter markets) were made 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 tax and legal advisors. Such provision is only recorded for lawsuits classified as probable losses. Additionally, it includes tax liabilities due to actions from the Company’s initiative, with appliance of Selic’s interest rates.

The Company is defending itself in other judicial and administrative proceedings (labor, civil, tax and environmental) in the approximate amount of R$3 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 followed in Brazil.

a) Labor Litigation:

Until December 31, 2006, CSN was defendant in 8,196 labor claims (7,232 claims in 2005), which required a provision in the amount of R$37,487 (R$27,170 in 2005). 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.

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$16,097 on December 31, 2006 (R$13,281 in 2005).

c) Environmental Actions:

On December 31, 2006, the Company recorded a provision of R$52,670 (R$24,062 in 2005) for investment in environmental recovery expenditures, mainly related to the Company’s plants in the States of Minas Gerais and Santa Catarina.

d) Tax Litigation:

• 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 granted. The proceeding is now under accounting inspection.

On December 31, 2006, the Company recorded R$326,313 (R$361,928 in 2005) as judicial deposit and a provision of R$20,892 (R$60,573 in 2005), which represents the portion not recognized by the courts.

(ii) In February 2003, the Company was charged by tax authorities related to the calculation of IRPJ and CSL of previous years in view of the fact that had tax losses carryforward above the 30% limit of taxable income, as provided for by laws.

On August 21, 2003, a decision was rendered by the second panel of the Judgment Federal Revenue Office in Rio de Janeiro related to the decision which made said tax deficiency notice null and void and a new Tax Deficiency Notice was issued about same matter in November 2003. The Company challenged such new Tax Deficiency Notice, which was rejected in administrative lower courts. An administrative appeal was brought against such decision, which was accepted in administrative appellate court on April 26, 2006, so that said Tax Deficiency Notice had favorable decision to CSN, on an irrevocable basis, and respective decision was

published in November 2006. On December 31,2005, the balance of such provision was R$193,218.

(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 these revenues from said calculation basis, as well as the offsetting of amounts paid 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 December 31, 2006, the amount of suspended liability and the offset credits based on the referred proceedings was R$787,500 (R$547,766 in 2005), plus Selic (Central Bank overnight rate).

• PIS/COFINS – Law 9,718/99

CSN is questioning the legality of Law 9,718/99, which increases the PIS and COFINS calculation bases, including the financial revenue of the Company. On December 31, 2006, provision amounts to R$317,947 (R$292,363 in 2005), 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 awaiting trial.

• CPMF

The Company was questioned the enforceability of CPMF, since the amendment to Constitution 21/99 was enacted. On May 31, 2006 unfavorable decision to the Company was published and said proceeding was closed on June 30, 2006 when the Company settled the obligation related to said tax.

• 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$23,985 on December 31, 2006 (R$22,786 in 2005), 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 Allowance

The Company discussed the unconstitutionality of the Education Allowance 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 Federal Regional 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, but CSN did not agree.

The Company filed new proceedings to question the above-mentioned facts and deposited in court the amounts due. In the first lawsuit, the 1^st level 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 December 31, 2006 amounts to R$33,121 (R$33,121 in 2005).

• 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 December 31, 2006 totals R$95,234 (R$76,699 in 2005), which includes legal charges.

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

• 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 – 2^nd Region reversed the favorable decision for CSN.

CSN filed a special appeal to the Superior Court of Justice (“STJ”) and an extraordinary appeal to the Federal Supreme Court (“STF”), which have not yet been judged.

On December 31, 2006, the provision referring to the total of credits already offset and kept in the Company’s liabilities amounted to R$1,445,537 (R$818,242 in 2005), adjusted by the Selic rate.

• 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 December 31, 2006, the provision related to the total credits already offset and recorded under the Company’s liabilities amounted to R$942,964 (R$708,633 in 2005), 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$53,353 on December 31, 2006 (R$44,875 in 2005), which includes legal charges.

i) PREPAID DIVIDENDS

On June 23, 2006 and August 3,2006, the Company’s Board of Directors approved, pursuant to article 31 of its Bylaws and article 204 and paragraphs 1 and 2, of Law 6404/76, the payment of dividends as prepaid dividends, in the amount of R$415,000 and R$333,000 corresponding to R$1.61219 and R$ 1.293638, respectively, per share outstanding on the date of approval of the payment.

ii) 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$174,428 in 2006, corresponding to the remuneration of R$0.67762 per share, in 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.

22. LOSS AF-III

On January 22, 2006 an accident involving equipment adjacent to Blast Furnace #3 took place, mainly affecting the powder collecting system and interrupted the equipment production until the end of the first semiannual period. The Company has an insurance policy for loss of profits and equipment in the maximum amount of US$750 million, which the Management deems as sufficient to recover any losses derived from the accident. The cause of the accident had its coverage by the policy expressly recognized by the insurance companies, and the work to calculate the losses is under the final phase.

The amount of losses subject to indemnification shown by regulating bodies up to the closing date of the Financial Statements is US$445 million or R$951 million, translated by the exchange rate as of December 31, 2006. Based on insurance policy and confident as to the conclusion of studies about the loss, CSN requested and the insurance companies granted an advance of US$237 million (equivalent to R$515 million received until January 2007, of which R$476 million was received up to December 31, 2006) as advance – such amount will be deducted from losses subject to indemnification, verified during the normal course of regulation process.

Based on reports issued by independent consultants and in the confirmation of insurance coverage on the part of insurance companies, the Company recorded, on a conservative basis, on account of minimum estimate of loss of profits indemnification up to December 31, 2006, the amount of R$730 million as “Other operating revenues” and R$19 million as “Non-operating income” corresponding to the income in the write-off of damaged assets (net book value of R$174 million).

On December 31, 2006 the Company maintained balance receivable from losses claimed in the amount of R$447 million. The Company does not identify any risk in such credit, taking into account the international reputation and prestige of insurance and reinsurance companies.

24. EMPLOYEES’ PENSION FUND

(i) Private Pension Administration

The Company is the principal sponsor of CBS Previdência, 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 Previdência congregates CSN employees, of CSN related companies and the entity itself, provided they sign the adherence agreement.

(ii) Description of characteristics of the plans

CBS Previdência 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 Variable Contribution (CV). Besides the programmed pension benefit, there is the payment of 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 December 31, 2006 and 2005, the plans are as follows (unaudited):


	2006	2005

Members	20,060	18,933

In service	9,316	7,972

Total participants (members/beneficiaries)	25,555	24,330

(iii) Settlement of actuarial deficit

According to the official letter 1555/SPC/GAB/COA, as of August 22, 2002, confirmed by official letter 1598/SPC/GAB/COA as 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/surpluses 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 371/00, 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, 2007.

Provisioned actuarial liabilities/ (assets) (Long-Term Liabilities/Other)	66,113	238,031	(17,204)	286,940

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 2006, the amount of R$63,540 (R$22,832 in 2005), in accordance with paragraphs 83 and 84 of NPC 26 of IBRACON approved by CVM Deliberation 371/2000, which, added to related disbursements, totaled R$111,832 (R$100,042 in 2005).

The balance of the provision for coverage of the actuarial liability on December 31, 2006 amounts to R$286,940 (R$223,400 until 2005).

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 Combined Supplementary Benefit Plan, 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$17,204 in 2006 (R$13,220 in 2005).

According to actuarial calculation prepared by the method of projected credit unit, the Company will appropriate R$4,293 and sponsor’s defined contributions of the combined supplementary benefit plan are estimated at R$12,445 for the next year.

Statements regarding the declaration or payment of dividends, the implementation of principal operating and financing strategies and capital expenditure plans, the direction of future operations and the factors or trends affecting financial condition, liquidity or results of operations are examples of forward-looking statements. Such statements reflect the current views of management and are subject to a number of risks and uncertainties. There is no guarantee that the expected events, trends or results will actually occur. The statements are based on many assumptions and factors, including general economic and market conditions, industry conditions, and operating factors. Any changes in such assumptions or factors could cause actual results to differ materially from current expectations.
