Foreign Currency Matters

ASC 830 governs accounting for foreign currency, built on the functional currency concept: each entity measures its assets, liabilities, and operations in the currency of the primary economic environment in which it operates (830-10-45-2), determined by weighing the cash flow, sales price, sales market, expense, financing, and intra-entity indicators of 830-10-55-5. From that foundation, 830-20 handles transactions denominated in a currency other than the functional currency—recorded at the transaction-date rate, remeasured at each balance sheet date at the current rate, with transaction gains and losses in net income except for economic hedges of a net investment and long-term-investment-nature intra-entity balances (830-20-35-2, 35-3)—while 830-30 handles translation of a foreign entity's statements into the reporting currency, with assets and liabilities at the balance sheet rate, income items at rates on the dates recognized, and translation adjustments in OCI (the CTA), released to earnings only upon sale or complete or substantially complete liquidation (830-30-45-3, 45-4, 40-1). Special rules override the model for highly inflationary economies, which require remeasurement as if the reporting currency were the functional currency (830-10-45-11), and 830-946 gives investment companies detailed, largely elective rules for isolating the foreign currency component of gains and losses (830-946-45-4, 50-1). The single most important idea: identify the functional currency first, then remeasure (gains/losses to income) before you translate (adjustments to OCI).

1. 10Overall58 ¶

   ASC 830-10 sets the scope and foundational framework for foreign currency accounting: it requires each foreign entity's assets, liabilities, and operations to be measured in that entity's functional currency—the currency of the primary economic environment in which it operates (830-10-45-2)—before amounts are translated into the reporting currency. It supplies the economic indicators (cash flow, sales price, sales market, expense, financing, and intra-entity indicators in 830-10-55-5) that management weighs to identify the functional currency, mandates remeasurement of books of record not kept in the functional currency using historical rates for specified nonmonetary items (830-10-45-17 through 45-18), and requires entities in highly inflationary economies (cumulative 3-year inflation ≈100% or more) to be remeasured as if the reporting currency were the functional currency (830-10-45-11).

2. 20Foreign Currency Transactions34 ¶

   ASC 830-20 governs how an entity accounts for transactions denominated in a currency other than its functional currency (foreign currency transactions). At the transaction date, each asset, liability, revenue, expense, gain, or loss is recorded and measured in the functional currency using the exchange rate in effect at that date (830-20-25-1; 830-20-30-1); thereafter, balances denominated in a foreign currency are remeasured at each balance sheet date at the current rate (830-20-35-2), with the resulting transaction gains and losses generally included in net income. Narrow exceptions—economic hedges of a net investment in a foreign entity and long-term-investment-nature intra-entity balances—are reported like translation adjustments in other comprehensive income (830-20-35-3).

3. 30Translation of Financial Statements38 ¶

   ASC 830-30 governs how a reporting entity translates the financial statements of a foreign entity whose functional currency is not the reporting currency, when those statements are consolidated, combined, or accounted for under the equity method. Assets and liabilities are translated at the balance sheet date rate and revenues, expenses, gains, and losses at the rates on the dates recognized; the resulting translation adjustments go to other comprehensive income (accumulated as the cumulative translation adjustment, or CTA) rather than net income. The CTA is released into earnings only upon sale or complete or substantially complete liquidation of the investment in the foreign entity.

4. 946Financial Services—Investment Companies64 ¶

   This Subtopic tells investment companies how to compute and report foreign currency transaction gains and losses on foreign-currency-denominated securities, cash, forward contracts, receivables/payables, income, and expenses. Ongoing revaluation of unsettled foreign-currency items produces unrealized foreign currency gain or loss, which is reclassified to realized gain or loss upon settlement (830-946-45-1). Critically, a fund is permitted—but not required—to separately isolate the foreign currency component of realized and unrealized gains and losses on investments, and it must disclose whichever practice it follows (830-946-45-4; 830-946-50-1).
