(4)Point (c) of Article 45(6) of Directive 2014/59/EU also requires that resolution authorities consider the possibility that certain classes of liabilities, identified in resolution plans and in the resolvability assessment, might be excluded from bail-in. Liabilities of that kind should not be relied on for purposes of meeting the MREL. Resolution authorities should also ensure that, when significant amounts of any insolvency class of liabilities are excluded from bail-in on either a mandatory or discretionary basis, that exclusion would not result in liabilities of the same or a more senior class bearing greater losses than they would in insolvency, as this would be an impediment to resolvability.
