CA-6.4.8
The risk-weighted asset amount of a securitisation exposure is computed by multiplying the amount of the position by the appropriate risk weight determined in accordance with the following tables. For off-balance sheet exposures, banks must apply a CCF and then risk weight the resultant credit equivalent amount. If such an exposure is rated, a CCF of 100% must be applied. For positions with long-term ratings of B+ and below and short-term ratings other than A-1/P-1, A-2/P-2, A-3/P-3, deduction from capital as defined in paragraph CA-6.4.2 is required. Deduction is also required for unrated positions with the exception of the circumstances described in paragraphs CA-6.4.12 to CA-6.4.16.
The following risk weights are applied in the standardised approach.
| Long term rating50 | Securitisation Exposure | Re-securitisation Exposure |
| AAA to AA- | 20% | 40% |
| A+ to A- | 50% | 100% |
| BBB+ to BBB- | 100% | 225% |
| BB+ to BB- | 350% | 650% |
| B+ and below or unrated | Deduction | Deduction |
| Short term rating | Securitisation Exposure | Re-securitisation Exposure |
| A-1/P-1 | 20% | 40% |
| A-2/P-2 | 50% | 100% |
| A-3/P-3 | 100% | 225% |
| All other ratings or unrated | Deduction | Deduction |
