- Definition

The item represents the difference, if any, between the amount at which an investment accounted for under the equity method of accounting is carried (reported) on the balance sheet and the amount of underlying equity in net assets the reporting Entity has in the investee. A difference can arise between the carrying value of the equity method investment and the value of the Entity's amount of underlying equity in net assets of the investee, for example, from appreciation of certain assets which is not recognized in earnings, but is recognized in other comprehensive income (a separate component of shareholders' equity) by the investee.
