Definition

Foreign-exchange gain (positive) or loss (negative) for the period from revaluing non-functional-currency balances and transactions. A SIGNED line; relevant for companies holding cash or transacting in multiple currencies.

Formula

Signed FX gain (positive) / loss (negative) for the period.

Why it matters

Can swing net income for multi-currency companies even when operations are stable.

How to interpret

Enter signed: gain positive, loss negative. Large swings should be footnoted as FX, not operating, effects.

Calculation policy

How an AI agent should compute this KPI from messy company data. Free-text rules consumed at reasoning time — not a deterministic DSL. The most common ways to get this wrong are listed under Common miscomputations.

Inclusion rules

  • SIGNED realized and unrealized foreign-exchange gain (positive) or loss (negative) from revaluing non-functional-currency balances and transactions for the period.

Exclusion rules

  • Foreign-currency operating revenue/expense translated at the transaction date — that hits the operating lines, not here.
  • Interest (finance.interest_income_expense).

Required inputs

  • Multi-currency balances with period-end rates, and realized FX on settled transactions.

Edge cases

  • Large swings should be footnoted as FX, not operating, effects.
  • The functional-currency designation determines what revalues.

Validation checks

  • Enter signed: gain positive, loss negative.
  • Exclude from burn and operating reads when material — it is a revaluation effect, not operations.

Common miscomputations

  • Leaving FX swings inside the operating lines — distorts the operating trend.
  • Sign errors on a loss.
