(9)The empowerment to adopt regulatory technical standards in Article 49(6) of Regulation (EU) No 575/2013 is closely linked with the empowerment in Article 21a(3) of Directive 2002/87/EC, since both deal with consistent application of the methods of calculation laid down in the Annex to that Directive. To ensure coherence in the methods of calculation specified for the purpose of those legislative acts and to facilitate a comprehensive view and compact access to them by persons subject to those obligations it is desirable to lay down the regulatory technical standards adopted pursuant to those empowerments in a single Regulation.
