(38)The criteria laid down in this Regulation defining the scope of institutions that are less significant should be applied at the highest level of consolidation within participating Member States based on consolidated data. Where the ECB carries out the tasks conferred on it by this Regulation with regard to a group of credit institutions that is not less significant on a consolidated basis, it should carry out those tasks on a consolidated basis with regard to the group of credit institutions and on an individual basis with regard to the banking subsidiaries and branches of that group established in participating Member States.
