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 6, "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 their 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 both December 31, 2014 and 2013, the fair value of these investments was less than $1 million. During the years ended December 31, 2014, 2013 and 2012, our Investment segment recorded gains of less than $1 million, $140 million and $310 million, respectively, associated with these investments. Such amounts are included in net 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 December 31, 2014, the Investment Funds no longer held any shares of Hain or MGM. The General Partners have applied the fair value option to their previously held investments in Hain and MGM. The portion of trading (losses) gains that relates to trading securities still held by our Investment segment for the years ended December 31, 2014, 2013 and 2012 was $(570) million, $2.9 billion and $697 million, respectively. 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. Other Segments The carrying value of investments held by our Automotive, Energy, Railcar and Gaming segments and the Holding Company consist of the following:
| December 31,

Equity method investments | $ | 298 |  |  | $ | 284 |
Other investments | 241 |  |  | 151 |
| $ | 539 |  |  | $ | 435 |
The 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 gain from investment activities in the consolidated statements of operations.
