5.2 Risk Components

No: BCS 290 Date(g): 12/6/2006 | Date(h): 16/5/1427 Status: No longer applicable
 Probability of default (PD) and loss given default (LGD)
 
5.2.1For each identified pool of retail exposures, banks are expected to provide an estimate of the PD and LGD associated with the pool, subject to the minimum requirements as set out in “Minimum Requirements for Risk Quantification under IRB Approach”. Additionally, the PD for retail exposures is the greater of the one- year PD associated with the internal borrower grade to which the pool of retail exposures is assigned or 0.03%.
 
 Banks may reflect the risk-reducing effects of guarantees and credit derivatives, either in support of an individual obligation or a pool of exposures, through an adjustment of either the PD or LGD estimate, subject to the minimum requirements in paragraphs 480 to 489 of the International Convergence of Capital Measurement and Capital Standards – June 2006. Whether adjustments are done through PD or LGD, they must be done in a consistent manner for a given guarantee or credit derivative type.
 
 (Refer para 332, International Convergence of Capital Measurement and Capital Standards – June 2006)
 
 Consistent with the requirements outlined above for corporate, sovereign, and bank exposures, banks must not include the effect of double default in such adjustments. The adjusted risk weight must not be less than that of a comparable direct exposure to the protection provider. Consistent with the standardized approach, banks may choose not to recognize credit protection if doing so would result in a higher capital requirement.
