Recognition of Credit Risk Mitigants

No: 44047144 Date(g): 27/12/2022 | Date(h): 4/6/1444 Status: In-Force
14.12Credit risk mitigants will be recognized generally using the same type of framework as set forth in paragraphs 12.21 to 12.2862.In particular, a guarantee provided by the seller or a third party will be treated using the existing IRB rules for guarantees, regardless of whether the guarantee covers default risk, dilution risk, or both.
 
 (1)If the guarantee covers both the pool’s default risk and dilution risk, the bank will substitute the risk weight for an exposure to the guarantor in place of the pool’s total risk weight for default and dilution risk.
 
 (2)If the guarantee covers only default risk or dilution risk, but not both, the bank will substitute the risk weight for an exposure to the guarantor in place of the pool’s risk weight for the corresponding risk component (default or dilution). The capital requirement for the other component will then be added.
 
 (3)If a guarantee covers only a portion of the default and/or dilution risk, the uncovered portion of the default and/or dilution risk will be treated as per the existing credit risk mitigation rules for proportional or tranched coverage (i.e. the risk weights of the uncovered risk components will be added to the risk weights of the covered risk components)
 

62 At SAMA’s discretion, banks may recognize guarantors that are internally rated and associated with a PD equivalent to less than A- under the foundation IRB approach for purposes of determining capital requirements for dilution risk.
