- Definition

This item represents the entity's proportionate share for the period of the operating income (loss) of its investees (such as unconsolidated subsidiaries and joint ventures) to which the equity method of accounting is applied, excluding pre-opening expenses. Such amount typically reflects adjustments to eliminate intercompany gains and losses, and to amortize, if appropriate, any difference between cost and underlying equity in net assets of the investee at the date of investment.
