SB-Deals®
In SB CertificatesSM, Freddie Mac guarantees senior classes of securities issued by third-party trusts and backed by Multifamily Small Balance Loans (SBLs). SBLs are underwritten by Freddie Mac at the time of origination for sale to Freddie Mac by a specialty network of Lenders or SBL Lenders. Freddie Mac may also purchase for securitization seasoned SBL loan pools in whole loan sales. Unlike K Certificates® and other Multifamily securities, Freddie Mac generally does not issue structured passthrough securities in SB-Deals®. The third-party trust issues the senior classes of securities guaranteed by Freddie Mac as well as unguaranteed subordinate securities.
General Structure
SB Certificates are generally structured as follows:
- Freddie Mac purchases and aggregates SBL loans, by a Seller or groups of Sellers, for securitization.
- Freddie Mac sells the SBL loans to a third-party depositor who deposits the loans into a third-party trust.
- The third-party trust issues private-label securities backed by the SBL loans.
- Freddie Mac guarantees the senior securities issued by the third-party trust, which are then publicly offered. In some cases, a third party may act as loan seller and Freddie Mac may issue structured pass-through securities.
- The private-label securities are not expected to be rated.
