Competent authorities should assess the reliability of the ICAAP calculations by assessing whether they are:

• a. granular: the calculations/methodologies should allow calculations to be broken down by risk type, rather than presenting a single (economic capital) calculation covering all risks;
• b. credible: the calculations/methodologies used should demonstrably cover the risk they are looking to address (e.g. the credit concentration risk calculation should use appropriate sector breakdowns that reflect actual correlations and portfolio compositions) and should be sufficiently robust, stable, risk sensitive and conservative to adequately quantify losses associated with the risks. Such calculations/methodologies should be consistent with the institutions’ strategic processes, including the institutions’ risk appet ite;
• c. understandable: the underlying drivers and key assumptions of the calculations/methodologies should be clearly specified. A ‘black box’ calculation should not be acceptable. Competent authorities should ensure that the institution provides an explanation of the key assumptions used, including at least time horizon, confidence levels, correlation assumptions, key parameters, the most fallible areas of the models used, and how these are accounted for and corrected in the final ICAAP calculation;
• d. comparable: the calculations/methodologies should clearly mention the main assumptions in terms of the overall level of conservatism, the holding periods/risk horizons and confidence levels (or equivalent measurement) in order to allow the adjustment that may be requested or enacted by competent authorities in order to facilitate comparability with peers and supervisory benchmarking.
