Foreign Currency Translation vs Remeasurement: Which Rate, Which Statement, and Why It Is a BAR Topic

A subsidiary's statements arrive in a currency the parent does not report in, and ASC 830 offers two ways to convert them. One is called translation and puts the difference in other comprehensive income, where it sits until the subsidiary is sold. The other is called remeasurement and puts the difference in net income this year. Same subsidiary, same rates, two different bottom lines, and the choice between them is not a choice at all: it is decided by a single fact, the subsidiary's functional currency.

The topic is examined in BAR under the 2026 Blueprint, alongside hedging and business combinations, and it is one that IFRS-trained candidates usually know half of. IAS 21 has the same functional currency concept and the same closing-rate translation; what it does not have is a method called remeasurement with the temporal rules attached, and that half is where the questions are.

The functional currency decides

The functional currency is the currency of the primary economic environment in which the entity operates: the one it generates and spends cash in. ASC 830 lists the indicators, and a question that gives you several of them is asking you to weigh them, not to count them.

Indicator	Points to the local currency when	Points to the parent's currency when
Cash flows	Mostly in local currency and not remitted to the parent	Directly affect the parent's cash flows and are remitted
Sales prices	Set by local competition and regulation	Set by worldwide competition or the parent's pricing
Sales market	Active local market	Sales mainly to the parent's country or in its currency
Expenses	Labour, materials and costs mostly local	Components mostly obtained from the parent's country
Financing	Local debt serviced from local operations	Financed by the parent, serviced by the parent
Intercompany volume	Low	High; the subsidiary is an extension of the parent

Once the functional currency is set, the conversion path follows mechanically.

Books kept in	Functional currency	Reporting currency	What happens
Local	Local	Parent's	Translate with the current rate method; difference to OCI
Local	Parent's	Parent's	Remeasure with the temporal method; difference to net income
Local	A third currency	Parent's	Remeasure into the functional currency, then translate into the reporting currency: both
Local, highly inflationary economy	Deemed to be the parent's	Parent's	Remeasure; a highly inflationary economy is one with cumulative inflation of roughly 100% over three years

The Gulf case is the one candidates get wrong through overconfidence. A Saudi subsidiary that sells in riyals to Saudi customers, pays Saudi staff and borrows from Saudi banks has the riyal as its functional currency, and is translated. A Saudi subsidiary that assembles components shipped from a US parent, prices in dollars and remits everything has the dollar as its functional currency, and is remeasured, even though every invoice it issues is in riyals. Because the riyal is pegged at 3.75 to the dollar the numbers barely move under either method, which is why the question is not about the numbers. It is about which method, and where the difference goes.

Translation: the current rate method

When the functional currency is the local one, the subsidiary's statements already measure its performance correctly and the parent only needs to express them in its own currency. Everything on the balance sheet is translated at the rate on the balance sheet date, the current rate; income statement items at the average rate for the period (or the actual rates, if the flows were uneven); and equity at the historical rates in force when each component arose. Because the balance sheet is at one rate and equity at another, the statements no longer balance, and the plug is the translation adjustment, reported in other comprehensive income and accumulated in equity as the cumulative translation adjustment.

The adjustment stays in OCI for as long as the parent holds the subsidiary. On sale or substantial liquidation it is reclassified into net income as part of the gain or loss on disposal. That is the reason a group with a decade of foreign subsidiaries can carry a large negative CTA in equity and show no expense for it: none of it has touched the income statement, and it will not until the investment is realised.

Remeasurement: the temporal method

When the books are kept in a currency that is not the functional currency, the statements have to be restated as though they had been kept in the functional currency all along. That is remeasurement, and its rule is the temporal method: each item is converted at the rate that would have applied had it been recorded in the functional currency at the time.

Item	Rate under the temporal method	Rate under the current rate method
Cash, receivables, payables, debt (monetary items)	Current	Current
Inventory at cost, property, intangibles (nonmonetary at historical cost)	Historical	Current
Nonmonetary items carried at fair value	Rate at the date the fair value was measured	Current
Revenue, most expenses	Average	Average
Cost of goods sold, depreciation, amortisation	Historical, matching the asset	Average
Equity	Historical	Historical
The balancing difference	Remeasurement gain or loss, in net income	Translation adjustment, in OCI

The logic of the temporal method is that the entity's exposure is its net monetary position. A subsidiary with more monetary liabilities than monetary assets in a currency that weakens against the functional currency records a gain, because the liabilities cost less to settle; the reverse produces a loss. Nonmonetary assets are not exposed, because their historical cost in the functional currency does not change when the local currency moves, and holding them at historical rates is what removes them from the calculation.

Two consequences appear in questions. Cost of goods sold is at the historical rate of the inventory it came from, so a question that gives you an average rate and an inventory purchased at a different rate wants the latter. And the remeasurement gain or loss is volatile: it changes net income every period the rate moves, which is exactly why a subsidiary that is an extension of the parent is treated this way. Its exposure is the parent's exposure.

Foreign currency transactions

The same mechanic in miniature applies to a single receivable or payable denominated in a foreign currency. It is recorded at the spot rate on the transaction date, remeasured at the current rate at each balance sheet date, and settled at the rate on the settlement date, with every difference in net income. A US company sells goods for 100,000 euros when the euro is 1.10: a receivable of 110,000 dollars. At year end the euro is 1.08: the receivable is 108,000 and a loss of 2,000 is recognised. The customer pays when the euro is 1.12: 112,000 is received and a gain of 4,000 is recognised. The transaction itself, the 110,000 of revenue, is never adjusted.

Remeasurement of a foreign subsidiary is this calculation applied to every monetary item at once. Translation is a different idea altogether: it does not measure exposure, it re-expresses a set of statements, which is why its difference bypasses income.

IAS 21, for the IFRS reader

IAS 21 uses the same functional currency definition and the same indicators, and translates to a presentation currency the same way: assets and liabilities at the closing rate, income and expenses at the rates on the transaction dates or an average, differences in OCI, reclassified on disposal. The differences are at the edges. IAS 21 does not name a "temporal method"; it requires an entity to measure its own transactions in its functional currency from the start, so remeasurement of a set of books kept in another currency is the same arithmetic without the label. For hyperinflationary economies IAS 29 restates the local statements for inflation first and then translates at the closing rate, where US GAAP remeasures into the parent's currency instead; the two approaches produce different figures, and a question that names the framework is telling you which. Goodwill and fair value adjustments on acquisition are treated as assets of the foreign operation and translated at the closing rate under both.

How BAR asks

Question pattern	What to do
Indicators listed, "what is the functional currency"	Weigh cash flows, prices, financing and intercompany volume; do not count
Functional equals local, "what rate for inventory"	Current rate; the difference goes to OCI
Functional equals parent's, "what rate for depreciation"	Historical rate of the related asset; the difference goes to net income
"Where is the translation adjustment reported"	OCI, accumulated in equity; reclassified on sale
Net monetary liability position, local currency weakens	Remeasurement gain in net income
Receivable in a foreign currency across year end	Remeasure at the closing rate; gain or loss in income; revenue unchanged
Highly inflationary economy	Functional currency is the reporting currency; remeasure

Where to practise this

The topic is a decision followed by a table of rates, and both are learned by working fact patterns until the method is chosen without hesitation. Prepito's BAR course covers functional currency, translation, remeasurement and foreign currency transactions with practice questions and simulations, and the FAR course covers the consolidation into which the translated statements flow, described in Consolidation Entries Explained. The companion BAR topic, where the OCI treatment reappears for a different reason, is Fair Value Hedge vs Cash Flow Hedge; the BAR study guide places both in the blueprint.
