Exchange rate variance. The exchange rate variance posting consists of a periodic revaluation (generally at the end of the year) of the balance in local currency of a bank account held in currency. In fact the balance of such an account takes into account the successive exchange rate affecting the corresponding currency. The exchange rate variance posting is passed from the account concerned to the account for the gain or loss on the exchange rate as a function of the sense of the variance.
