Base amount

Base amount (or base value, or basic amount, or basic value) (, ; commonly abbreviated as "БВ" or "б. в.") is sort of notional amount used in Belarus to keep amount of pensions, scholarship, social welfare payments, duties, taxes, and fines in the text of laws stable and relevant regardless of the level of the inflation.
History.
Until 2002, fines, taxes, fees and other payments in Belarus were calculated in multiples up to the minimum wage. In accordance with the Presidential Decree № 3 of 15.02.2002, the minimum wage is used only in labor relations. According to the Resolution of the Council of Ministers of 22.02.2002 № 243 for the calculation of fines, taxes, fees and other payments, a base amount of 10 000 belarusian rubles (about 6.92 euro at that time) is applied.
Simplified approximation.
As seen above, from 2005 year base amount is set in amount that can be approximated to 10 euro. For example, if the amount of some fine is 35 base amounts, it can be easily assumed as 350 euro.
The U.S. Department of State in the Travel Information uses an approximation of 2 base amounts to 25 euro, which covers the actual amount on the safe side.
