Article 138 - General requirements
Table of content
An institution may nominate one or more ECAIs to be used for the determination of risk weights to be assigned to assets and off-balance sheet items. An institution may revoke its nomination of an ECAI. An institution shall substantiate the revocation if there are concrete indications that the intention underlying the revocation is to reduce the capital adequacy requirements. Credit assessments shall not be used selectively. An institution shall use solicited credit assessments. However it may use unsolicited credit assessments if EBA has confirmed that unsolicited credit assessments of an ECAI do not differ in quality from solicited credit assessments of this ECAI. EBA shall refuse or revoke this confirmation in particular if the ECAI has used an unsolicited credit assessment to put pressure on the rated entity to place an order for a credit assessment or other services. In using credit assessment, institutions shall comply with the following requirements:
where only one credit assessment is available from a nominated ECAI for a rated item, that credit assessment shall be used to determine the risk weight for that item;
where two credit assessments are available from nominated ECAIs and the two correspond to different risk weights for a rated item, the higher risk weight shall be assigned;
where more than two credit assessments are available from nominated ECAIs for a rated item, the two assessments generating the two lowest risk weights shall be referred to. If the two lowest risk weights are different, the higher risk weight shall be assigned. If the two lowest risk weights are the same, that risk weight shall be assigned.
