Investments
Investments in Unconsolidated Entities Policy	We generally account for investments under the equity method when we have an ownership interest of 20 to 50 percent. In these cases, our pro rata shares of the entities' net assets are included in Investments on the Consolidated Balance Sheets. These investments are adjusted for our share of each investee's earnings or losses, dividends, and other comprehensive income or loss. The carrying value of unconsolidated entities is evaluated for impairment under the U.S. GAAP provisions for equity method investments.

Disclosure of accounting policy for the equity method of accounting for investments in common stock or other interests including unconsolidated subsidiaries, corporate joint ventures, noncontrolling interests in real estate ventures, limited partnerships, and limited liability companies. The accounting policy may include information such as: (1) initially recording an investment in the stock of an investee at cost; (2) adjusting the carrying amount of the investment to recognize the investor's share of the earnings or losses of the investee after the date of acquisition; and (3) adjustments to reflect the investor's share of changes in the investee's capital (dividends). This disclosure may also include a detailed description of the policy for determining the amount of equity method losses recognized after an investment has been reduced to zero as a result of previous losses, reasons for not using the equity method when the investor company owns 20 percent or more of the voting stock of the investee's company (including identification of the significant investee), reasons for using the equity method when the ownership percentage is less than 20 percent, and discussion of recognition of equity method losses when an investor's total investment in an investee includes, in addition to an investment in common stock, other investments such as preferred stock and loans to the investee. An entity also may describe how such investments are assessed for impairment.
