1. In the case where a credit institution calculating risk-weighted exposure amounts under Articles 78 to 83 has more than one form of credit risk mitigation covering a single exposure (e.g. a credit institution has both collateral and a guarantee partially covering an exposure), the credit institution shall be required to 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 Articles 78 to 83 and this Annex.
2. When credit protection provided by a single protection provider has differing maturities, a similar approach to that described in point 1 shall be applied.
