1.9 This consultation is relevant to PRA-authorised banks, building societies, PRA-designated investment firms, and PRA-approved or PRA-designated financial or mixed financial holding companies (collectively 'firms').

1.10 PRA-authorised banks, building societies and designated investment firms that meet the 'Simpler-regime criteria' definition, as specified in paragraph 1.53 below, Chapter 2 - Scope and levels of application, and Appendix 9, would not have to apply the proposed implementation of the Basel 3.1 standards set out in this CP, but could choose to be subject to them. However, the proposals should still be of interest to all firms meeting these criteria, for the reasons set out in paragraphs 1.53 to 1.56 below. The PRA invites responses from such firms on the proposals set out in this CP, including how aspects could be adjusted for future application to them.
