Foreign currency transactions and translation

Regional SaaS groups routinely bill customers, pay vendors, and consolidate subsidiaries across multiple currencies, so an incorrect functional currency conclusion or mechanical retranslation error compounds every period, misstating both transaction-level FX gains/losses in profit or loss and the cumulative translation reserve in equity used to assess group financial health. Because functional currency is assessed by substance rather than by where an entity is incorporated, a mismatch between the assumed and true functional currency can silently distort results for years before being caught.

For each entity in the group, which currency mainly drives sales prices, labor costs, and financing, and does that support the functional currency currently used? Are intercompany balances denominated in currencies different from the functional currency of either party, creating transaction-level exposures that need monitoring? Is there any exposure to a hyperinflationary economy that would require IAS 29 restatement before translation?

1. Determine each entity's functional currency first, based on the primary economic environment it operates in: the currency that mainly influences sales prices, and the currency of the country whose competitive forces and regulations mainly determine those prices, plus the currency that mainly influences labor, material and other costs.
2. Do not default to the currency of incorporation or the parent's presentation currency without performing this substance-based analysis, especially where pricing is set in USD but costs are local currency.
3. Record foreign currency transactions initially at the spot exchange rate on the transaction date.
4. At each reporting date, retranslate monetary items (cash, receivables, payables, borrowings) at the closing rate, recognizing the resulting exchange difference in profit or loss.
5. Do NOT retranslate non-monetary items measured at historical cost (including deferred revenue/contract liabilities, which are non-monetary obligations to deliver service, not to pay cash), leave them at the exchange rate on the date of the original transaction.
6. For consolidation, translate a foreign operation's assets and liabilities at the closing rate and income and expenses at rates approximating the transaction dates (often average rates), recognizing the resulting difference in other comprehensive income within a foreign currency translation reserve, not profit or loss.

Measure and recognize transaction-level exchange differences on monetary items in profit or loss each period as the closing rate diverges from the rate at initial recognition or the prior reporting date. Measure the cumulative translation adjustment on consolidation as the difference arising from translating opening net assets at the current closing rate versus the prior closing rate, plus the effect of translating the period's profit or loss at average rates versus the closing rate used for the balance sheet, accumulated in OCI/equity until the foreign operation is disposed of. Reassess functional currency only when there is a genuine, sustained change in the underlying economic indicators, not for short-term fluctuations, and apply any change prospectively from the date of the change.

Disclose: the amount of net foreign exchange gains and losses recognized in profit or loss; the amount of exchange differences arising during the period and reclassified/accumulated in the foreign currency translation reserve within equity; the functional currency of significant foreign operations and any changes therein with the reason; the presentation currency and, if different from the functional currency of the parent, the reason for the difference; significant judgments applied in determining functional currency for entities with mixed currency indicators.

• Retranslating deferred revenue/contract liabilities at the closing rate as if they were monetary, creating artificial FX gains or losses that should not exist for a non-monetary obligation to deliver service
• defaulting functional currency to the entity'
• s local incorporation currency without analyzing pricing, cost, and financing indicators, especially for USD-priced regional subsidiaries with local-currency costs
• ignoring intercompany balances and unrealized FX on intercompany loans that should eliminate on consolidation or be assessed for whether they form part of the net investment in a foreign operation
• changing functional currency retrospectively rather than prospectively when circumstances genuinely shift
• using period-end spot rates for income statement translation instead of average rates without justification, when average rates better approximate the transaction pattern.
