Article 383 › 4
An institution which is permitted by the competent authority in accordance with Article 283 to use IMM to calculate exposure values in relation to the majority of its business, but which uses the methods set out in Section 3, Section 4 or Section 5 of Title II, Chapter 6 for smaller portfolios, and which has permission to use the market risk internal model for the specific risk of debt instruments in accordance with point (d) of Article 363(1) may, subject to permission from the competent authorities, calculate the own funds requirements for CVA risk in accordance with paragraph 1 for the non-IMM netting sets. Competent authorities shall grant this permission only if the institution uses the methods set out in Section 3, Section 4 or Section 5 of Title II, Chapter 6 for a limited number of smaller portfolios. For the purposes of a calculation under the preceding subparagraph and where the IMM model does not produce an expected exposure profile, an institution shall do both of the following: (a) assume a constant EE profile; (b) set EE equal to the exposure value as computed under the methods set out in Section 3, Section 4 or Section 5 of Title II, Chapter 6, or IMM for a maturity equal to the greater of: (i) half of the longest maturity occurring in the netting set; (ii) the notional weighted average maturity of all transactions inside the netting set.
