(3)Article 18(6), points (a) and (b), of Regulation (EU) No 575/2013 refer to the supervisory requirements for prudential consolidation in the case of significant influence over one or more institutions or financial institutions but without participation or other capital ties, and in the case where those institutions or financial institutions are placed under single management other than pursuant to a contract, memorandum or articles of association, respectively. To determine whether a situation of significant influence exists, competent authorities should take into account several indicators of significant influence. Moreover, a situation of single management should only be determined where the competent authority has concrete evidence that there is an effective coordination of the financial and operating policies of such institutions or financial institutions.
