Table: Risk weighted exposure amounts for retail exposures

Correlation (R) |
0.03 × (1 - EXP(-35*PD))/(1-EXP(-35)) + 0.16* |
[1-(1-EXP(-35*PD))/(1-EXP(-35))] |

Risk weight (RW) |
(LGD*N[(1-R)-0.5*G(PD)+(R/(1-R))0.5 *G(0.999)]-PD*LGD)* 12.5*1.06 |
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. |
equals RW*exposure value |
