Rule CA-1.1.8 is in addition to the other requirements in Module CA. If a firm's own assessment suggests its required capital is less than the regulatory minima specified in this Module, the latter must still be complied with. Where a firm's assessment suggests that a higher level of capital should be held, the CBB would expect firms to hold capital in line with their assessment. The CBB is not prescribing the detailed form such assessments should take, in order to give firms flexibility to develop their own approaches. Nonetheless, the CBB would expect the sophistication of such assessments to match the risk profile of the firm concerned.
