(20)Regulation (EU) No 575/2013 provides that competent authorities are able to waive the application of certain solvency and liquidity requirements for credit institutions permanently affiliated to a central body (‘cooperative networks’) where certain specific conditions are met. To take account of the specificities of such cooperative networks, the Board should also be able to waive the application of the MREL that applies to such credit institutions and the central body under similar conditions to those set out in Regulation (EU) No 575/2013 where credit institutions and the central body are established in the same Member State. The Board should also be able to treat credit institutions and the central body as a whole when assessing the conditions for resolution depending on the features of the solidarity mechanism. The Board should be able to ensure compliance with the external MREL requirement of the resolution group as a whole in different ways, depending on the features of the solidarity mechanism of each group, by counting eligible liabilities of entities that, in accordance with the resolution plan, are required by the Board to issue instruments eligible for the MREL outside the resolution group.
