(3)While NCAs are primarily responsible for reviewing the arrangements, processes, mechanisms and strategies implemented by credit institutions that are classified as less significant to ensure a sound management and coverage of their risks – including their provisioning policies and treatment of assets in terms of own funds requirements – the ECB, in its oversight role within the SSM, should promote the consistent application of high supervisory standards in the execution of such reviews. In this context, a consistent application of high supervisory standards to the supervisory review of management and coverage of non-performing exposures (NPEs) for less significant supervised entities across the SSM contributes to the broader objectives of ensuring that: (a) a coherent and effective prudential supervisory approach is implemented with respect to all credit institutions in the participating Member States; (b) the single rulebook for financial services is applied consistently to all credit institutions in the participating Member States; and (c) all credit institutions in the participating Member States are subject to supervision of the highest quality.
