The Single Security is on target for implementation in Freddie Mac’s platform in 2017 and is set to reach the second stage in 2018, according to officials speaking at the Mortgage Bankers Association secondary market conference last week. David Applegate, CEO of Common Securitization Solutions, the joint venture owned by the GSEs that is building the Common Securitization Platform, said in 2018 Fannie Mae will switch its to-be-announced business to the CSP and begin issuing Single Securities that will be fully interchangeable with Freddie Single Securities. The GSE plans to use the CSP for all of its new mortgage-backed securities issues, including non-to-be-announced products such as securities backed by adjustable-rate mortgages, said Renee Schultz, senior vice president of capital markets at Fannie.
