(4)A set of clear qualitative and appropriate quantitative criteria should be established in order to identify the core categories of staff whose professional activities have a material impact on an institution's risk profile, ensuring a harmonised approach across the Union and covering a common set of the most relevant risks. In accordance with Article 94(2) of Directive 2013/36/EU, all the categories of staff identified by those criteria must be of staff whose professional activities have a material impact on an institution's risk profile. Institutions should also take into account the results of their own risk assessments within their internal procedures. Competent authorities should ensure a complete identification of all staff whose professional activities have a material impact on an institution's risk profile.
