The Office of the Comptroller of the Currency, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation, the Securities Exchange Commission, the Federal Housing Finance Agency and the U.S. Department of Housing and Urban Development (the "Agencies") sought comment on a joint proposed rule to revise the proposed rule the Agencies published in the Federal Register on April 29, 2011, and to implement the credit risk retention requirements of section 15G of the Securities Exchange Act of 1934 (15 U.S.C. 78o-11), as added by section 941 of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Section 15G generally requires the securitizer of asset-backed securities to retain not less than 5 percent of the credit risk of the assets collateralizing the asset-backed securities. Section 15G includes a variety of exemptions from these requirements, including an exemption for asset-backed securities that are collateralized exclusively by residential mortgages that qualify as "qualified residential mortgages," as such term is defined by the Agencies by rule.
