Maturity Mismatch
CA-4.7.27
A maturity mismatch is a situation where the residual maturity of the CRM is less than that of the underlying credit exposure. In the case of a maturity mismatch with the CRM having a maturity of less than one year, the CRM is not recognised. This means that a CRM with a maturity mismatch is only permitted where its original maturity is at least one year. The simple approach must not be used for CRM with maturity mismatches.

The following adjustment must be applied for a CRM with a maturity mismatch:
Pa = P x (t -0.25) / (T – 0.25), where:
Pa = adjusted value of risk mitigation
P = value of risk mitigation used (e.g. collateral or guarantee amount)
T = min (5, residual maturity of the exposure) in years
t = min (T, residual maturity of the risk mitigation) in yearsJanuary 2015
