FACE="Times New Roman" SIZE="2">Investments

The Company’s financial statements consolidate the operations and accounts of the
Company and all subsidiaries in which the Company has a controlling interest. The Company also has investments in associated companies that are accounted for under the equity method and, because the operations of these companies are integrated with
the Company’s basic steelmaking operations, its proportionate share of their income (loss) is reflected in the Company’s cost of products sold in the consolidated statements of operations. In addition, the Company holds investments in debt
securities and minor holdings in equity securities, which are accounted for as available-for-sale or held-to-maturity cost investments. At December 31, 2007, the Company had no investments that it accounted for as trading securities. Each of
the Company’s investments is subject to a review for impairment, if and when, circumstances indicate that a loss in value below its carrying amount is other than temporary. Under these circumstances, the Company would write the investment down
to its fair value, which would become its new carrying amount.

The Company’s investment in AFSG Holdings, Inc. represents the
carrying value of its discontinued insurance and finance leasing businesses, which have been largely liquidated. The activities of the remaining operating companies are being classified as “runoff” and the companies are accounted for,
collectively, as a discontinued operation under the liquidation basis of accounting, whereby future cash inflows and outflows are considered. The Company is under no obligation to support the operations or liabilities of these companies.
