Fluctuation of the foreign currency exchange rates.
EXAMPLE:
Your USD bank account shows these balances but you want to have the CAD balance as $ 1100.00 based on an exchange rate of 1.1.
Exchange rate = (Desired balance – Current Balance) + 1 = (1100 – (-400)) + 1 = 1501
Debit the US Bank Account by USD $ 1.00, credit the Foreign Currency Exchange Gain or Loss account

| Foreign Amount | Debits | Credits | |
| US Bank account | US$ 1.00 | 1501.00 | |
| Foreign Currency Exchange Gain/Loss account | US$ 1.00 | 1501.00 |
Exchange rate = 1
credit the US Bank Account by USD $ 1.00 and debit the Foreign Currency Exchange Gain or Loss account

| Foreign Amount | Debits | Credits | |
| US Bank account | US$ 1.00 | 1.00 | |
| Foreign Currency Exchange Gain/Loss account | US$ 1.00 | 1.00 |
