(8)To ensure consistency in the measurement of material risks that investment firms could pose to others or face themselves, competent authorities should rely on a harmonised set of minimum indicative qualitative metrics. Given that risks evolve throughout the business cycle of a firm, competent authorities should perform not only a static assessment, but also perform a historical trend analysis of such metrics. To cover all the relevant risks properly, different metrics should be used for investment firms with different business models and activities. In order to properly cover all the relevant risks of the investment firm, taking into account the specific business model or activity, legal form and the availability of reliable data, competent authorities should, under certain conditions notably pertaining to the specificities of a firm’s business model or data quality, adjust the metrics and use those adjusted metrics or, if that is not possible, use alternative metrics that are proportionate to the investment firm’s size, complexity, business model, and operating model and that would ensure an appropriate assessment of the risks.
