2. Subject to the approval of the competent authorities, the amount referred to in point (b) of paragraph 1 may be replaced by a requirement to hold own funds which are at all times more than or equal to 80 % of the own funds that the institution would be required to hold under Article 92 calculating riskweighted exposure amounts in accordance with Part Three, Title II, Chapter 2, and Part Three, Title III, Chapter 2 or 3, as applicable, instead of in accordance with Part Three, Title II, Chapter 3, or Part Three, Title III, Chapter 4, as applicable.
3. A credit institution may apply paragraph 2 only if it started to use the IRB Approach or the Advanced Measurements Approaches for the calculation of its capital requirements on or after 1 January 2010.
4. Compliance with the requirements of point (b) of paragraph 1 shall be on the basis of amounts of own funds fully adjusted to reflect differences in the calculation of own funds under Directive 93/6/EEC and Directive 2000/12/EC as those Directives stood prior to 1 January 2007 and the calculation of own funds under this Regulation deriving from the separate treatments of expected loss and unexpected loss under Part Three, Title II, Chapter 3, of this Regulation.
5. The competent authorities may, after consulting EBA, waive the application of point (b) of paragraph 1 to institutions provided that all the requirements for the IRB Approach set out in Part Three, Title II, Chapter 3, Section 6 or the qualifying criteria for the use of the Advanced Measurement Approach set out in Part Three, Title III, Chapter 4, as applicable, are met.
6. By 1 January 2017, the Commission shall submit a report to the European Parliament and the Council on whether it is appropriate to extend the application of the Basel I floor beyond 31 December 2017 to ensure that there is a backstop to internal models, taking into account international developments and internationally agreed standards. That report shall be accompanied by a legislative proposal if appropriate.
