(17)To ensure a smooth transition for institutions that already have permission to use the AMA or that have applied for a permission to use the AMA before the entry into force of this Regulation, it should be provided that competent authorities apply this Regulation in relation to the assessment of the AMA of these institutions only after a certain transitional period. Given that the regular review of the AMA referred to in Article 101(1) of Directive 2013/36/EU is usually performed on an annual basis, that transitional period should be a year from the date of entry into force of this Regulation.
