- Definition

The aggregate unrealized foreign currency transaction gain (loss) (pretax) included in determining net income for the reporting period. Represents the aggregate of gains (losses) on transactions that are unsettled as of the balance sheet date, which is therefore an adjustment to reconcile income (loss) from continuing operations to net cash provided by or used in continuing operations. Excludes foreign currency transactions designated as hedges of net investment in a foreign entity and intercompany foreign currency transactions that are of a long-term nature, when the entities to the transaction are consolidated, combined, or accounted for by the equity method in the reporting entity's financial statements. For certain entities, primarily banks, that are dealers in foreign exchange, foreign currency transaction gains (losses) may be disclosed as dealer gains (losses).
