ANNEX IXU.K.SECURITISATION

PART 3U.K.External credit assessments

2.USE OF CREDIT ASSESSMENTSU.K.

2.A credit institution may nominate one or more eligible ECAIs the credit assessments of which shall be used in the calculation of its risk-weighted exposure amounts under Articles 94 to 101 (a ‘nominated ECAI’).U.K.

3.Subject to points 5 to 7 below, a credit institution must use credit assessments from nominated ECAIs consistently in respect of its securitisation positions.U.K.

4.Subject to points 5 and 6, a credit institution may not use an ECAI's credit assessments for its positions in some tranches and another ECAI's credit assessments for its positions in other tranches within the same structure that may or may not be rated by the first ECAI.U.K.

5.Where a position has two credit assessments by nominated ECAIs, the credit institution shall use the less favourable credit assessment.U.K.

6.Where a position has more than two credit assessments by nominated ECAIs, the two most favourable credit assessments shall be used. If the two most favourable assessments are different, the least favourable of the two shall be used.U.K.

7.Where credit protection eligible under Articles 90 to 93 is provided directly to the SSPE, and that protection is reflected in the credit assessment of a position by a nominated ECAI, the risk weight associated with that credit assessment may be used. If the protection is not eligible under Articles 90 to 93, the credit assessment shall not be recognised. In the situation where the credit protection is not provided to the SSPE but rather directly to a securitisation position, the credit assessment shall not be recognised.U.K.

[F17a. Competent authorities shall, furthermore, take the necessary measures to ensure that, with regard to credit assessments relating to structured finance instruments, the ECAI is committed to make available publicly the explanation how the performance of pool assets affects its credit assessments.] U.K.
