*Value at Risk (“VaR”) is a measure of the potential loss in value of a portfolio over a defined period for a given confidence interval. A one-day VaR at the 95% confidence level represents that there is a 5% probability that the mark-to-market loss on the portfolio over a one day horizon will exceed this value (assuming normal markets and no trading in the portfolio).
