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 = 0 
For PD = 0, RW shall be: 0 

PD = 1 
For PD = 1: 

(i) 
for defaultedexposures where a firm applies the LGD values set out in BIPRU 4.4.32R and BIPRU 4.8.25R RW shall be: 0; 

(ii) 
for defaultedexposures where a firm uses its own estimates of LGDs, RW shall be: Max {0, 12.5 *(LGDEL_{BE})}; 

where EL_{BE}must be the firm's best estimate of expected loss for the defaultedexposure according to BIPRU 4.3.122 R.

Expected loss amount 

For defaultedexposures (PD = 1) where a firm uses its own estimates of LGDs, EL must be EL_{BE,} 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.
