Except as stated in Paragraph CA-6.3.2, conventional bank licensees are required to hold regulatory capital against all of their securitisation exposures and re-securitisation exposures, including those arising from the provision of credit risk mitigants to a securitisation transaction, investments in asset-backed securities, retention of a subordinated tranche, and extension of a liquidity facility or credit enhancement, as set forth in the remainder of this section. Repurchased securitisation exposures must be treated as retained securitisation exposures.
