Consider a portfolio consisting of N=500 assets with equal credit ratings. Assume that for every asset i E {1,..., N} the notional is 10,000 USD, the EAD is equal to 100%, PD 2%, LGD;-30%, i {1,..., N} and LGDs are deterministic. Defaults are assumed to be statistically independent. Derive the expected value and standard deviation of the portfolio loss.
