Six federal regulators, including the Federal Housing Finance Agency, re-proposed risk-retention requirements, as well as the definition for qualified residential mortgages this week, making significant changes that had been sought by lenders. The new proposal revises a proposed rule the agencies issued in 2011 to implement the risk-retention requirement of the Dodd-Frank Act. Among other things, the rule would recognize the full guaranty on payments of principal and interest provided by Fannie Mae and Freddie Mac for their residential mortgage-backed securities as meeting the risk-retention requirements while the two GSEs are in conservatorship or receivership and have capital support from the federal government.
