Foreign currency translation

Foreign currency translation converts a foreign entity's functional-currency statements into the reporting currency using current and average rates, with the resulting adjustment recorded in other comprehensive income rather than net income.

CORAA TeamUpdated November 5, 2026

Definition

When a foreign entity's functional currency is not the reporting currency, its statements are translated. Assets and liabilities use the exchange rate at the balance sheet date. Revenues and expenses use the rates when they were recognized or a weighted-average rate for the period. Equity accounts use historical rates. The balancing amount is the translation adjustment, reported in other comprehensive income under ASC 830-30-45-12 and accumulated in equity.

Why it matters in an audit or review

Translation errors move equity and the cash flow statement without touching earnings, so they are easy to miss. The accumulated translation adjustment is released into net income only when the investment is sold or substantially liquidated (ASC 830-30-40-1). Exchange gains and losses on foreign-currency transactions follow ASC 830-20 and generally go through net income.

Example

Illustrative: a subsidiary has net assets of 1,000,000 British pounds. The rate is $1.25 at the start of the year and $1.30 at the end, with no income or dividends. Net assets move from $1,250,000 to $1,300,000 and the $50,000 increase is a translation gain in other comprehensive income.

Common mistakes

  • Putting translation adjustments through net income.
  • Using the closing rate for income statement items without disclosing it.

  • Other comprehensive income
    Other comprehensive income covers gains and losses that GAAP records in equity instead of net income, such as translation adjustments and certain securities items, and it adds to net income to give comprehensive income.
