N(x) |
denotes the cumulative distribution function for a standard normal random variable (i.e. the probability that a normal random variable with mean zero and variance of one is less than or equal to x). |
G(z) |
denotes the inverse cumulative distribution function for a standard normal random variable (i.e. the value x such that N(x) = z). |
PD = 1 |
For PD = 1 (defaultedexposure), RW must be: Max {0, 12.5 *(LGD- ELBE)} where ELBEmust be the firm's best estimate of expected loss for the defaultedexposure according to BIPRU 4.3.122 R. |
