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

It is in pre-operational phase and will remain so until the completion of Rail Network II. The approved schedule, which considered the completion of the work by January 2017, is currently under discussion with the responsible bodies, according described in the item 28.c. The Management of TLSA understands that new deadlines for project completion will not have material adverse effects on the expected return on investment. During the year 2017, the others shareholders of TLSA subscribed 2,912,997 shares in amounting to R$153,253, diluting CSN on TLSA share capital to 46.30%. Therefore, due to the transactions described above and the participation change of the shareholders in the share capital of TLSA on 2017, the Company recognized a gain of R$2,814, recorded in equity in other comprehensive income. The Management receives funds from its shareholders and third parties for completion of the works, according described in the item 28.c, which are expected to be available, based on agreements previously entered into and recent discussions between the involved parties. After analyzing this matter, Management concluded as adequate the use of the accounting base of the project’s going concern in the preparation of the financial statements for the year ended December 31, 2018. TLSA performed an impairment test of its own long-live assets using the discount cash flow method and considered the main assumptions, as follows: Measurement of recoverable value:
Cash Flow Projection | Until 2057
Gross Margin | Based on market studies to capture operations costs and loads, based on studies of market trends.
Estimated Costs | Costs based on studies and market trends.
Growth rate in perpetuity | Growth rate was not considered due to the projection model until the end of the concession.
Discount rate | Between 5.1% to 7.9% in real terms.
In addition, CSN, as an investor, performed an impairment test of its stake in TLSA, through TLSA ability to distribute dividends, methodology known as Dividend Discount Model, or DDM, to remunerate the capital invested by shareholders. In order to perform this test, some aspects were taken into account, such as:
| · | The flow of dividends was obtained from the TLSA nominal cash flow;
| · | The flow of dividends was calculated considering the annual percentages of participation, considering the dilutions of the CSN’s stakes due to the amortization of debts;
| · | This flow of dividends was discounts at present value using cost of equity (Ke) embedded in the WACC rate of TLSA; and
| · | This Ke obtained was the one calculated in the “rolling WACC” of TLSA.
