Computational Framework & Statutory Formulas

Transaction Conversion
Base Currency Equivalent = Foreign Amount × Exchange Rate (₦)
Converts foreign invoice or asset into functional Nigerian Naira reporting currency.
IAS 21 FX Variance (Gain / Loss)
FX Variance = Foreign Amount × (Settlement Rate - Initial Booking Rate)
Differentiates between realized gains/losses on settled transactions and unrealized revaluations at balance sheet date.

Nigerian Economic & Statutory Context

Following the consolidation of foreign exchange markets by the Central Bank of Nigeria (CBN), companies translate foreign transactions at official Nigerian Autonomous Foreign Exchange Market (NAFEM) rates. Under IAS 21, monetary items denominated in foreign currency must be revalued at each reporting date, recognizing FX variances in the statement of comprehensive income.

Frequently Asked Questions (FAQ)

What is the difference between realized and unrealized FX gain/loss under IAS 21?

A realized FX gain or loss occurs when a foreign currency transaction is actually settled in cash (e.g. paying an import bill or receiving client funds). An unrealized FX gain or loss is an accounting revaluation of outstanding monetary assets or liabilities at the balance sheet date based on closing exchange rates.

Are unrealized foreign exchange losses tax-deductible under Nigerian tax law?

Historically, the FIRS disallows unrealized exchange losses because they do not represent incurred commercial outlays under Section 24 of CITA. Tax deductibility is generally granted upon actual realization when the transaction is completed.
