BIPRU 5.9 Combinations of credit risk mitigation in the standardised approach
In the case where a firm calculating risk weighted exposure amounts under the standardised approach has more than one form of credit risk mitigation covering a single exposure (e.g. a firm has both collateral and a guarantee partially covering an exposure), the firm must subdivide the exposure into parts covered by each type of credit risk mitigation tool (e.g. a part covered by collateral and a portion covered by guarantee) and the risk weighted exposure amount for each portion must be calculated separately in accordance with the provisions of the standardised approach and BIPRU 5.
[Note: BCD Annex VIII Part 5 point 1]
When credit protection provided by a single protection provider has differing maturities, a similar approach to that described in BIPRU 5.9.1 R must be applied.
