What is the difference between translating a foreign branch and translating a foreign subsidiary?

- Using closing rates for P&L — income and expenses must use transaction-date rates (or a reasonable average), not the closing rate.

IAS 21 Translation of Foreign Operations

IAS 21 Translation of Foreign Operations — Core Rule

When a foreign operation's financial statements are prepared in its functional currency, those statements must be translated into the reporting entity's presentation currency before consolidation or application of the equity method. IAS 21.38 establishes the foundational principle: any entity whose presentation currency differs from its functional currency must translate its results and financial position into the presentation currency. The translation method applied to foreign operations builds on the general translation requirements and adds specific procedures governed by IAS 21.44.

How IAS 21 Translation of Foreign Operations Works

The translation of a foreign operation follows a three-rate approach:

Assets and liabilities — translated at the closing rate at the date of the statement of financial position
Income and expenses — translated at the exchange rates at the dates of the transactions (in practice, average rates are acceptable when they approximate actual rates)
Equity items — translated at historical rates (the rates at the dates those equity transactions originally occurred)

All resulting exchange differences are recognised in other comprehensive income (OCI) and accumulated in a separate component of equity, often called the foreign currency translation reserve (FCTR).

Practical journal entry example

Assume a EUR-functional subsidiary is consolidated into a USD-presentation group. At year-end, the net assets translate at the closing rate, but income and expenses were translated at average rates. The difference arising is:

Dr Foreign Currency Translation Reserve (OCI) / Cr Equity — translation difference
(or the reverse, depending on the direction of currency movement)

This difference is never recycled through profit or loss while the operation is held — it sits in equity until disposal.

IAS 21.45 adds that normal consolidation procedures still apply — intragroup balances and transactions are eliminated — but any exchange difference on an intragroup monetary item that forms part of the net investment in a foreign operation cannot be eliminated against the translation difference. Instead, it remains in OCI at the consolidated level.

Where a foreign operation's reporting date differs from that of the reporting entity, IAS 21.46 permits the use of a different date provided the gap is no greater than three months and adjustments are made for significant transactions in that intervening period.

IAS 21 Translation of Foreign Operations — Common Pitfalls

Using closing rates for P&L — income and expenses must use transaction-date rates (or a reasonable average), not the closing rate. Mixing this up overstates or understates reported profit.

Recycling the FCTR too early — the accumulated translation reserve is only reclassified to profit or loss on disposal (full or partial, depending on circumstances) of the foreign operation. Do not release it on impairment alone.
Hyperinflationary foreign operations — if a foreign operation's functional currency is that of a hyperinflationary economy, IAS 21.43 requires the financial statements to be restated under IAS 29 before applying the translation method. Skipping the restatement step is a frequent error.
Intragroup loans as net investment — loans that are neither planned nor likely to be settled form part of the net investment. Exchange differences on these items flow to OCI, not P&L, which surprises preparers who treat all intragroup balances symmetrically.
Change in functional currency — per IAS 21.35, any change in functional currency is applied prospectively from the date of change. Restating prior periods is not permitted.
