Article 139
Issuer and issue credit assessment
1.
Where a credit assessment exists for a specific issuing programme or facility to which the item constituting the exposure belongs, this credit assessment shall be used to determine the risk weight to be assigned to that item.
2.
Where no directly applicable credit assessment exists for a certain item, but a credit assessment exists for a specific issuing programme or facility to which the item constituting the exposure does not belong or a general credit assessment exists for the issuer, then that credit assessment shall be used in either of the following cases:
(a)
In all other cases, the exposure shall be treated as unrated.
3.
Paragraphs 1 and 2 are not to prevent the application of Article 129.
