"For financial institutions, foreign exchange (FX) rates commonly constitute the most important part of the market risk. In order to assess the risk of opened position various models can be used. However, since real FX returns exhibit higher than normal kurtosis and since the very far tails of the distribution should also be measured, the Monte Carlo simulation of multidimensional L'evy processes seems to be the most efficient approach. In this paper we apply two basic copula functions to connect multidimensional L\u00E9vy models and provide a model for portfolio probability distribution. Next, VaR (and AVaR) is calculated and the backtesting procedure is carried out." . . "1"^^ . "2009-02-03+01:00"^^ . . "RIV/61989100:27510/09:00018530!RIV11-GA0-27510___" .
