(6)The prudential backstop should not prevent competent authorities from exercising their supervisory powers in accordance with Directive 2013/36/EU. Where competent authorities ascertain on a case-by-case basis that, despite the application of the prudential backstop for NPEs established by this Regulation, the NPEs of a specific institution are not sufficiently covered, it should be possible for them to make use of the supervisory powers provided for in Directive 2013/36/EU, including the power to require institutions to apply a specific provisioning policy or treatment of assets in terms of own funds requirements. Therefore, it is possible, on a case-by-case basis, for the competent authorities to go beyond the requirements laid down in this Regulation for the purpose of ensuring sufficient coverage for NPEs.
