Assume the the yield curve changes are parallel and normally distributed with a monthly mean of O basis point and a monthly standard deviation of 40 basis points (0.40%). Explain how the portfolio manager would calculate the 1-month 95% and 99% Value-at-Risk of her bond portfolio based on this information. Recall N(1.6449) = 0.95 and N(2.3263) = 0.99, where N(-) is the cumulative distribution function of a standard normal random variable
