Single Security Tabletop Market Readiness Testing

June 21, 2018

Freddie Mac and Fannie Mae will be facilitating a walk-through of key security activities later this year for the new Uniform Mortgage-Backed Security℠ (UMBS). As we start hitting critical Single Security milestones this year, we want you to have a chance to better understand any impacts to your upstream and/or downstream processes prior to the June 3, 2019 go-live date.

We’re looking for interested parties, including Seller/Servicers, to join us in the planning and execution of this tabletop testing exercise. This activity will include simulating pool formation, forward pricing, TBA trading, commingling securities and exchanging Freddie Mac Participation Certificates (PCs). As a participant, you’ll have early insights and a direct view into how the UMBS will flow through your systems and processes.

The results of the exercise will be shared with the market in 4Q 2018. 

Interested in joining? Email Barbara Pak of Freddie Mac at We’re convening a working group in July to kick off this process.
