CA-14.11.12
A bank must calculate the incremental risk measure according to Paragraph CA-14.11.7 and the comprehensive risk measure according to Paragraph CA-14.11.9 at least weekly, or more frequently as directed by its supervisor. The capital charge for incremental risk is given by a scaling factor of 1.0 times the maximum of (i) the average of the incremental risk measures over 12 weeks; and (ii) the most recent incremental risk measure. Likewise, the capital charge for comprehensive risk is given by a scaling factor of 1.0 times the maximum of (i) the average of the comprehensive risk measures over 12 weeks; and (ii) the most recent comprehensive risk measure. Both capital charges are added up. There will be no adjustment for double counting between the comprehensive risk measure and any other risk measures.
