Foreign Exchange Calculations

Unrealised Gain / Loss on Exchange

The Total Unrealised Gain / Loss on exchange for FX transactions that are not Fixed Rate is calculated as the UnallocatedAmount (FX) / Revaluation Exchange Rate, less the UnallocatedAmountBs, calculated at the transaction exchange rate.

As the unallocated amount is reduced by allocation, the Unrealised Gain / Loss is reduced accordingly. When a transaction is fully allocated total Unrealised Gain / Loss for the transaction is zero.

Realised Gain / Loss on Exchange

Realised Gain / Loss for a transaction is calculated during allocation as DebitAllocationAmountBs less CreditAllocationAmountBs.

Realised Gain / Loss occurs in the period of the allocation and is assigned to one of the transactions in the allocation based on a rule. Fixed rate transactions may incur Realised Gain / Loss.

Invoices and Credits take the Gain / Loss over Payments, Receipts and Journals, where both transactions for an allocation are from the same grouping (for example, Invoices and Credits being the first group, and Receipts, Payments, Journals the second), the earlier transaction takes the Gain / Loss.

Unrealised Revaluation Reserve

Unrealised Revaluation Reserve is the Bank Account Balance or Exchange Rate used on Revalue Bank accounts, less Bank Account Balance BS before Revaluation.

Unrealised variation is cleared when the bank account balance goes to zero.
