Members of the single-security and common securitization platform industry advisory group met last month for the second time and are considering more frequent meetings and subcommittees. The group also confirmed that the implementation date of the single security won’t occur at the beginning or end of a quarter and said the industry will have a 12- to 15-month advance notice prior to implementation. The group, created in preparation for the launch of the common securitization platform and single security, met at Fannie Mae’s headquarters to discuss a wide range of concerns raised by members and industry stakeholders, according to notes summarizing the meeting.
