For example the FX rate for closing balance at year end is 0,9 EUR/ 1 USD and 0,85 EUR / 1 USD as average which is used for P&L. When I translate this to my domestic currency (EUR) I get a difference of 1 EUR due to using of different FX rates:

And to balance I need to put this 1 EUR as a Translation reserve (in Equity).
