These Regulations implement in part the provisions relating to capital buffers in Directive 2013/36/EU of the European Parliament and of the Council of 26 June 2013 on access to the activity of credit institutions and the prudential supervision of credit institutions and investment firms (OJ no L176, 27/6/2013, p. 338; for corrigenda see OJ no L208, 2/8/2013, p.73). This directive (“the capital requirements directive”) is part of a package of EU legislation commonly known as “CRD4”. Articles 128 to 142, 160 and 162 of the capital requirements directive are concerned with capital buffers. Further implementation of the capital buffers provisions will be achieved through rules, or other binding requirements, imposed by the Prudential Regulation Authority (“PRA”) and Financial Conduct Authority (“FCA”).
