12 CFR § 3.41 - Operational requirements for securitization exposures.
(a) Operational criteria for traditional securitizations. A national bank or Federal savings association that transfers exposures it has originated or purchased to a securitization SPE or other third party in connection with a traditional securitization may exclude the exposures from the calculation of its risk-weighted assets only if each condition in this section is satisfied. A national bank or Federal savings association that meets these conditions must hold risk-based capital against any credit risk it retains in connection with the securitization. A national bank or Federal savings association that fails to meet these conditions must hold risk-based capital against the transferred exposures as if they had not been securitized and must deduct from common equity tier 1 capital any after-tax gain-on-sale resulting from the transaction. The conditions are:
(4) The securitization does not:
(i) Include one or more underlying exposures in which the borrower is permitted to vary the drawn amount within an agreed limit under a line of credit; and
(ii) Contain an early amortization provision.
(b) Operational criteria for synthetic securitizations. For synthetic securitizations, a national bank or Federal savings association may recognize for risk-based capital purposes the use of a credit risk mitigant to hedge underlying exposures only if each condition in this paragraph (b) is satisfied. A national bank or Federal savings association that meets these conditions must hold risk-based capital against any credit risk of the exposures it retains in connection with the synthetic securitization. A national bank or Federal savings association that fails to meet these conditions or chooses not to recognize the credit risk mitigant for purposes of this section must instead hold risk-based capital against the underlying exposures as if they had not been synthetically securitized. The conditions are:
(1) The credit risk mitigant is:
(i) Financial collateral;
(iii) A credit derivative that meets all criteria as set forth in the definition of “eligible credit derivative” in § 3.2, except for the criteria in paragraph (3) of the definition of “eligible guarantee” in § 3.2.
(2) The national bank or Federal savings association transfers credit risk associated with the underlying exposures to one or more third parties, and the terms and conditions in the credit risk mitigants employed do not include provisions that:
(i) Allow for the termination of the credit protection due to deterioration in the credit quality of the underlying exposures;
(c) Due diligence requirements for securitization exposures.
(1) Except for exposures that are deducted from common equity tier 1 capital and exposures subject to § 3.42(h), if a national bank or Federal savings association is unable to demonstrate to the satisfaction of the OCC a comprehensive understanding of the features of a securitization exposure that would materially affect the performance of the exposure, the national bank or Federal savings association must assign the securitization exposure a risk weight of 1,250 percent. The national bank's or Federal savings association's analysis must be commensurate with the complexity of the securitization exposure and the materiality of the exposure in relation to its capital.
(2) A national bank or Federal savings association must demonstrate its comprehensive understanding of a securitization exposure under paragraph (c)(1) of this section, for each securitization exposure by:
(i) Conducting an analysis of the risk characteristics of a securitization exposure prior to acquiring the exposure, and documenting such analysis within three business days after acquiring the exposure, considering:
(A) Structural features of the securitization that would materially impact the performance of the exposure, for example, the contractual cash flow waterfall, waterfall-related triggers, credit enhancements, liquidity enhancements, fair value triggers, the performance of organizations that service the exposure, and deal-specific definitions of default;
(B) Relevant information regarding the performance of the underlying credit exposure(s), for example, the percentage of loans 30, 60, and 90 days past due; default rates; prepayment rates; loans in foreclosure; property types; occupancy; average credit score or other measures of creditworthiness; average LTV ratio; and industry and geographic diversification data on the underlying exposure(s);
(C) Relevant market data of the securitization, for example, bid-ask spread, most recent sales price and historic price volatility, trading volume, implied market rating, and size, depth and concentration level of the market for the securitization; and
(D) For resecuritization exposures, performance information on the underlying securitization exposures, for example, the issuer name and credit quality, and the characteristics and performance of the exposures underlying the securitization exposures; and
(ii) On an on-going basis (no less frequently than quarterly), evaluating, reviewing, and updating as appropriate the analysis required under paragraph (c)(1) of this section for each securitization exposure.
