    • CA-5.7.8

      Banks using the standardised approach for a portion of their credit risk exposures, either on a transitional basis (as defined in paragraphs CA-5.2.44 and CA-5.2.45), or on a permanent basis if the exposures subject to the standardised approach are immaterial (paragraph CA-5.2.46), must determine the portion of collective impairment provisions attributed to the standardised or IRB treatment of provisions (see section CA-2.1 (d) according to the methods outlined in paragraphs CA-5.7.9 and CA-5.7.10.)

    • CA-5.7.9

      Banks should generally attribute total provisions on a pro rata basis according to the proportion of credit risk-weighted assets subject to the standardised and IRB approaches. However, when one approach to determining credit risk-weighted assets (i.e. standardised or IRB approach) is used exclusively within an entity, provisions booked within the entity may be attributed to that approach.

    • CA-5.7.10

      Subject to CBB's discretion, banks using both the standardised and IRB approaches may rely on their internal methods for allocating provisions for recognition in capital under either the standardised or IRB approach, subject to the following conditions. Where the internal allocation method is made available, the CBB will establish the standards surrounding their use. Banks will need to obtain prior approval from CBB to use an internal allocation method for this purpose.
