The framework for prudential supervision established by Directive 2013/36/EU requires that institutions identify all members of staff whose professional activities have a material impact on the institution's risk profile. Any criteria used for this purpose must ensure that the identification of relevant staff reflects the level of risk of different activities within the institution. The ECB is responsible for ensuring that the entities under its direct supervision apply the rules on the identification of relevant staff in a coherent manner that safeguards the soundness of any such identification. It has therefore adopted a Decision (Decision (EU) 2015/2218) providing for a procedure in relation to the application of the quantitative criteria set out in Article 4 of Delegated Regulation (EU) No 604/2014.
