Investments and Related Matters [Abstract] |
Investments and Related Matters | Investments and Related Matters. Investment Investments, and securities sold, not yet purchased consist of equities, bonds, bank debt and other corporate obligations, and derivatives, all of which are reported at fair value in our consolidated balance sheets. See Note 5, "Fair Value Measurements - Investment," for details of the investments for our Investment segment. Our Investment segment assesses the applicability of equity method accounting with respect to its investments based on a combination of qualitative and quantitative factors, including overall stock ownership of the Investment Funds combined with those of our affiliates along with board of directors representation. Our Investment segment applied the fair value option to certain of its investments that would have otherwise been subject to the equity method of accounting. As of June 30, 2013, the fair value of these investments was $376 million. During the three months ended June 30, 2013 and 2012, our Investment segment recorded gains of $22 million and $46 million, respectively. During the six months ended June 30, 2013 and 2012, our Investment segment recorded gains of $62 million and $167 million, respectively. Such amounts are included in net (loss) gain from investment activities in our consolidated statements of operations. Included in these investment gains and losses is the Investment Funds' gains and losses in The Hain Celestial Group, Inc. (“Hain”) and Metro-Golden-Mayer Inc. ("MGM"). As of June 30, 2013, the Investment Funds, together with their affiliates held, in the aggregate, approximately 15% of the outstanding shares of Hain. As of June 30, 2013, the Investment Funds no longer held any shares of MGM. The General Partners have applied the fair value option to their investments in Hain and previously to MGM. We believe that these investments to which we applied the fair value option are not material, individually or in the aggregate, to our consolidated financial statements. Hain is a registered SEC reporting companies whose financial statements are available at www.sec.gov. Other Segments The carrying value of investments held by our Automotive, Energy, Gaming, Railcar and Home Fashion segments and our Holding Company consist of the following:
| June 30, 2013 |  | December 31, 2012
| (in millions)
Equity method investments | $ | 311 |  |  | $ | 299 |
Other investments | 170 |  |  | 108 |
| $ | 481 |  |  | $ | 407 |
Our Holding Company applies the fair value option to its investments that would otherwise be subject to the equity method of accounting. We record unrealized gains and losses for the change in fair value of such investments as a component of net (loss) gain from investment activities in the consolidated statements of operations. We believe that these investments, individually, and in the aggregate, are not material to our consolidated financial statements.
