Article 337 › 2

The Supervisory Formula Method set out in Article 262 may be used where the institution can produce estimates of PD, and where applicable exposure value and LGD as inputs into the Supervisory Formula Method in accordance with the requirements for the estimation of those parameters under the Internal Ratings Based Approach in accordance with Title II, Chapter 3. An institution other than an originator institution that could apply it for the same securitisation position in its non-trading book may only use that method subject to permission by the competent authorities, which shall be granted where the institution fulfils the condition in the first subparagraph. Estimates of PD and LGD as inputs to the Supervisory Formula Method may alternatively also be determined based on estimates that are derived from an IRC approach of an institution that has been granted permission to use an internal model for specific risk of debt instruments. The latter alternative may be used only subject to permission by the competent authorities, which shall be granted if those estimates meet the quantitative requirements for the Internal Ratings Based Approach set out in Title II, Chapter 3. In accordance with Article 16 of Regulation (EU) No 1093/2010, EBA shall issue guidelines on the use of estimates of PD and LGD as inputs when those estimates are based on an IRC approach.
