Correlation (R)

[1(1EXP(35*PD))/(1EXP(35))] 

Risk weight (RW) 
(LGD*N[(1R)^{0.5}*G(PD)+(R/(1R))^{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 EL_{BE})} where EL_{BE}must be the firm's best estimate of expected loss for the defaultedexposure according to BIPRU 4.3.122 R.
