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). |

for defaultedexposures where a firm uses its own estimates of LGDs, RW shall be: Max {0, 12.5 *(LGD-ELBE)}; |

Expected loss amount |
|
For defaultedexposures (PD = 1) where a firm uses its own estimates of LGDs, EL must be ELBE, the firm's best estimate of expected loss for the defaultedexposure according to BIPRU 4.3.122 R. |
|
For exposures subject to the treatment set out in BIPRU 4.4.79 R (Double default) EL must be 0. |
