Recital 42

(42)The ‘evolutionary’ nature of this Directive enables credit institutions to choose amongst three approaches of varying complexity. In order to allow especially small credit institutions to opt for the more risk-sensitive IRB Approach, the competent authorities should implement the provisions of Article 89(1)(a) and (b) whenever appropriate. Those provisions should be read as such that exposure classes referred to in Article 86(1)(a) and (b) include all exposures that are, directly or indirectly, put on a par with them throughout this Directive. As a general rule, the competent authorities should not discriminate between the three approaches with regard to the Supervisory Review Process, i.e. credit institutions operating according to the provisions of the Standardised Approach should not for that reason alone be supervised on a stricter basis.
