12 CFR §324.45

1. (a)General.
   1. (1)An originating FDIC-supervised institution that has obtained a credit risk mitigant to hedge its exposure to a synthetic or traditional securitization that satisfies the operational criteria provided in § 324.41 may recognize the credit risk mitigant under §§ 324.36 or 324.37, but only as provided in this section.
   2. (2)An investing FDIC-supervised institution that has obtained a credit risk mitigant to hedge a securitization exposure may recognize the credit risk mitigant under §§ 324.36 or 324.37, but only as provided in this section.
2. (b)Mismatches. An FDIC-supervised institution must make any applicable adjustment to the protection amount of an eligible guarantee or credit derivative as required in § 324.36(d), (e), and (f) for any hedged securitization exposure. In the context of a synthetic securitization, when an eligible guarantee or eligible credit derivative covers multiple hedged exposures that have different residual maturities, the FDIC-supervised institution must use the longest residual maturity of any of the hedged exposures as the residual maturity of all hedged exposures.
