MBS Trust Agreements

When Fannie Mae issues an MBS, that security represents an undivided beneficial interest in a pool of mortgage loans or participation interests in mortgage loans held in trust pursuant to the terms of a governing trust document.

The Master Trust Agreement, or the Trust Indenture, including its exhibits and supplements, generally sets forth the terms relating to an issuance of MBS, the loans or participation interests in the pool, and payment terms on the MBS.
