In plain words
Many manufacturers buy materials in US dollars or euros on credit while earning in local currency. How are rate movements recorded? Under IAS 21, the purchase is recorded at the transaction-date exchange rate. At each reporting date, open foreign-currency payables and receivables are retranslated at the closing rate, with the gain or loss in profit or loss. The inventory cost already recorded does not change.
Why it matters
Import-dependent manufacturers routinely carry large open USD/EUR payables and LC exposures against local-currency revenue and cash flows; retranslation at closing rates flows directly through profit or loss every period, and a single sharp devaluation (as seen repeatedly in EGP) can wipe out a full year's operating margin or turn a profitable quarter into a loss, making this a top misstatement and earnings-volatility risk in the sector.
Diagnostic questions
What proportion of costs is FX-denominated versus the entity's revenue currency, and are open USD/EUR payables or LC liabilities retranslated at the closing rate each reporting date? Which exchange rate is used when official and parallel/informal rates diverge or convertibility is restricted? Is the resulting FX gain or loss correctly recognized in profit or loss (not adjusted into inventory cost already recorded)?
Recognition
- Identify the functional currency of the entity (usually SAR/EGP/AED based on the primary economic environment), not just the invoice currency.
- Record all import purchases and export sales at the spot rate on the transaction date.
- Classify USD/EUR payables, receivables and outstanding letter-of-credit (LC) liabilities as monetary items.
- At each reporting date, retranslate all open monetary items at the closing rate; recognize the resulting FX gain or loss in profit or loss (finance/FX line), not in revenue or cost of sales.
- Do not adjust the cost of inventory already recorded for subsequent exchange rate movements on the related payable - once inventory cost is fixed at the transaction-date rate, later FX movements are a financing item.
- Where multiple official/parallel rates exist, select and consistently apply the rate at which the entity can actually settle the obligation, and document the basis.
Measurement
Monetary items (cash, receivables, payables, LC liabilities in foreign currency) are retranslated at the closing spot rate at each reporting date; non-monetary items already measured at historical cost (e.g. inventory, PP&E) are not retranslated for subsequent FX movements once initially recorded. Where official and parallel/informal rates diverge, or transferability/convertibility is restricted, use the rate at which the entity could realistically settle the transaction or repatriate funds, not necessarily the official published rate, with the judgment and its basis disclosed. Re-measurement is triggered at every reporting date for open monetary balances, and immediately on settlement (realized FX gain/loss) when the item is paid or collected.
Presentation & disclosure
Present net FX gains/losses on operating monetary items within finance costs/income or a clearly labelled separate line, applied consistently period to period; disclose the accounting policy for functional currency determination and rate selection; disclose the amount of net FX gain/loss recognized in profit or loss for the period; disclose qualitative and, where practicable, quantitative sensitivity to major currency exposures (e.g. a reasonably possible devaluation scenario); disclose any exchange restrictions or rate multiplicity affecting realizability of foreign balances.
Common mistakes
- Leaving USD-denominated LC liabilities and payables at historical rates instead of retranslating at each period end
- capitalizing post-purchase-date devaluation losses into inventory cost rather than expensing through P&
- L
- netting FX gains and losses from unrelated exposures/counterparties without disclosure, obscuring the true exposure
- using an official rate for translation when the entity can only realistically settle at a parallel/black-market rate
- treating advances to suppliers denominated in foreign currency as monetary when they are actually non-monetary prepayments for goods (and therefore should not be retranslated).
Simple example
An Egyptian appliance assembler imports compressors from South Korea on 30-day credit. On 1 June it purchases components for USD 100,000 when EGP/USD = 47.00 (cost EGP 4,700,000). By the 30 June reporting date, EGP/USD has moved to 49.50, so the payable must be retranslated, creating an unrealized FX loss of EGP 250,000 (USD 100,000 x (49.50-47.00)). Entry on purchase (1 June): Dr Inventory - Components 4,700,000 / Cr Accounts Payable (USD) 4,700,000. Entry at reporting date (30 June) to retranslate the payable: Dr FX Loss (P&L - finance/FX) 250,000 / Cr Accounts Payable (USD) 250,000. The inventory cost of EGP 4,700,000 is not adjusted.
Professional judgment
The central judgment is rate selection when official and parallel/black-market rates diverge, or when exchange controls limit convertibility or repatriation - management must assess the rate at which the entity could realistically settle the obligation or convert the balance, which may not be the central bank's official published rate. A second judgment area is distinguishing monetary items (retranslated) from non-monetary items such as supplier advances or deposits (not retranslated). A third is determining functional currency itself when a manufacturer sources predominantly in USD/EUR but sells predominantly in local currency - the functional currency test looks at the currency that mainly influences sales prices and costs, not simply the invoicing currency, and a wrong call materially changes which balances are exposed to retranslation at all.
