(3)Directive 2013/36/EU makes clear that the identification and allocation methodology is harmonised in all Member States by the use of uniform and transparent parameters for determining an overall score of an entity to measure its systemic importance. In order to ensure that the sample of banks and banking groups both of the Union and authorised in third countries serving as a reference to reflect the global financial system are uniform across the Union, the European Banking Authority (EBA) should determine that sample. Exclusions and additions to that sample based on supervisory judgment should be chosen strictly to ensure its function as a term of reference and should not be based on other grounds.
