(10)The provisions of this Regulation are closely linked, since they refer to extensions and/or changes to AMA and IRB approaches for own funds requirements for credit and operational risk and since relevant supervisory issues and procedures are similar for those two types of internal approaches. To ensure coherence between those provisions, and to facilitate a comprehensive view and access in a coordinated fashion to them by persons subject to relevant obligations, it is desirable that they enter into force at the same time and include all of the regulatory technical standards required by Regulation (EU) No 575/2013 on extensions and changes to internal models for credit and operational risk, in a single Regulation. However, since point (a) in the first subparagraph of Article 312(4) deals with a different subject matter, this regulation only addresses points (b) and (c).
