What it means
A group with operations in several countries keeps local books in local currency. Before those books can be consolidated, every figure has to be converted into one reporting currency, and the choice of rate for each line is what makes translation more than simple arithmetic.
Under the widely used current rate method, assets and liabilities are translated at the closing rate on the balance sheet date. Income and expenses are translated at the average rate for the period, and share capital stays at the historical rate that applied when it was contributed.
Because three different rates are used, the translated balance sheet does not balance by itself. The difference is posted to a reserve called the cumulative translation adjustment, which sits within equity and does not touch reported profit until the subsidiary is eventually sold.
This matters commercially because it separates two very different effects. A translation difference is an accounting consequence of exchange rate movement, whereas a transaction difference arises when a company genuinely buys or sells in a foreign currency and does flow through profit.
The nuance worth knowing is the functional currency decision, meaning the currency of the environment in which the subsidiary mainly operates. If a foreign subsidiary actually prices, sells and pays in the parent's currency, its functional currency may be the parent's, and a different translation approach applies.
In practice
Real-world examples.
Example
A US software group reports flat group revenue despite every regional office growing in local currency. The finance director explains to the board that a stronger dollar reduced the translated value of European and Japanese sales, and shows the same figures at constant exchange rates to make the underlying growth visible.
Example
A manufacturer with a large Canadian subsidiary sees group equity fall by $6,000,000 in a year with no operating problems. The fall is entirely the cumulative translation adjustment, and a covenant tested on net assets nearly breaches as a result.
Example
A retail group sells its Australian subsidiary after twelve years. The accumulated translation reserve of $9,000,000 that had been sitting quietly in equity is recycled into profit on disposal, producing a gain that surprises analysts who had not read the equity statement.
Think of it
“Foreign currency translation converts foreign subsidiary numbers to your home currency for consolidation.
Formula
Calculation
Translated amount = Foreign currency amount x Applicable exchange rate
Cumulative Translation Adjustment = Net assets at the closing rate - Equity translated at historical and average rates
Worked example: a US parent owns a European subsidiary that keeps its books in euros. At the year end the subsidiary has assets of 10,000,000 euros and liabilities of 6,000,000 euros. The closing rate is $1.10 per euro. Share capital of 3,000,000 euros was contributed when the rate was $1.25, and retained earnings of 1,000,000 euros were earned at an average rate of $1.15.
Assets translated = 10,000,000 x $1.10 = $11,000,000.
Liabilities translated = 6,000,000 x $1.10 = $6,600,000.
Net assets at the closing rate = $11,000,000 - $6,600,000 = $4,400,000.
Share capital at the historical rate = 3,000,000 x $1.25 = $3,750,000.
Retained earnings at the average rate = 1,000,000 x $1.15 = $1,150,000.
Equity before any adjustment = $3,750,000 + $1,150,000 = $4,900,000.
Cumulative translation adjustment = $4,400,000 - $4,900,000 = -$500,000.
The group reports a translation reserve of -$500,000 within equity, and reported profit for the year is entirely untouched by it. If the euro later strengthens back to $1.25, that reserve unwinds without any manager having done anything differently.Case study
Seen in the real world.
Halden Instruments is an illustrative, invented group used here to show how translation can distract a board. The company manufactured in one country, sold through subsidiaries in four others, and reported in dollars.
Over two years its overseas subsidiaries grew local revenue by 14% and local profit by 19%, yet the group income statement showed revenue up only 3% and profit essentially flat. The board spent two meetings questioning the country managers before the group controller demonstrated that the entire difference came from average exchange rates having moved against the dollar.
Halden changed its management reporting rather than its accounting. Every internal pack now shows results at both actual and constant exchange rates, with the translation effect stated as a separate line, so managers are judged on what they control and the board still sees the reported group numbers.
Watch out
Common mistakes.
- Translating every line at the closing rate. Income and expenses arise throughout the year, so an average rate is used for them, and using the closing rate overstates or understates results.
- Treating the translation reserve as a real cash gain or loss. It is an unrealised accounting balance that only reaches profit if the foreign operation is sold.
- Confusing translation with transaction exposure. Invoicing a customer in a foreign currency creates a real gain or loss in profit, which is a different problem with different hedging answers.
Questions
People also ask.
What is the functional currency?
It is the currency of the main economic environment in which an entity operates, and it determines which translation method applies rather than simply following the country of incorporation.
Why does the cumulative translation adjustment sit in equity?
Because it reflects the change in value of a net investment in a foreign operation rather than the performance of that operation during the period.
Can a company hedge translation risk?
It can, usually by borrowing in the same currency as the foreign net assets, though many groups decide the accounting effect is not worth the cost and interest charge of hedging.
