ArcelorMittal (MT) | Analysis of Investments

Investment Accounting Policy

Investment in associates, joint ventures and other entities

Investments in associates and joint ventures, in which ArcelorMittal has the ability to exercise significant influence, are accounted for under the equity method. The investment is carried at the cost at the date of acquisition, adjusted for ArcelorMittal's equity in undistributed earnings or losses since acquisition, less dividends received and any impairment incurred.

Any excess of the cost of the acquisition over ArcelorMittal's share of the net fair value of the identifiable assets, liabilities, and contingent liabilities of the associate or joint venture recognized at the date of acquisition is recognized as goodwill. The goodwill is included in the carrying amount of the investment and is evaluated for impairment as part of the investment.

ArcelorMittal reviews all of its investments in associates and joint ventures at each reporting date to determine whether there is an indicator that the investment may be impaired. If objective evidence indicates that the investment is impaired, ArcelorMittal calculates the amount of the impairment of the investments as being the difference between the higher of the fair value less costs to sell or its value in use and its carrying value. The amount of any impairment is included in income from investments in associates and joint ventures in the consolidated statements of operations.

Investments in other entities, over which ArcelorMittal and/or its Operating Subsidiaries do not have the ability to exercise significant influence and have a readily determinable fair value, are accounted for at fair value with any resulting gain or loss recognized in the reserves in equity. To the extent that these investments do not have a readily determinable fair value, they are accounted for under the cost method.

Other investments

ArcelorMittal classifies its investments in equity securities that have readily determinable fair values as available-for-sale, which are recorded at fair value. Unrealized holding gains and losses, net of the related tax effect, on available-for-sale equity securities are reported as reserves, a separate component of equity, until realized. Realized gains and losses from the sale of available-for-sale securities are determined on a first-in, first-out basis.

Investments in privately held companies that are not considered equity method investments and for which fair value is not readily determinable are carried at cost less impairment.
