Mortgage-Backed Securities
We have been under conservatorship, with the Federal Housing Finance Agency acting as conservator, since Sept. 6, 2008. We also have entered into a senior preferred stock purchase agreement with the U.S. Department of the Treasury pursuant to which Treasury has committed to provide funding to us under specified circumstances. More information regarding the conservatorship and our agreement with Treasury is provided in our most recent Form 10-K, and may be supplemented by information in any subsequent Form 10-Qs, which are available under "SEC Filings."

Overview of Products

Single-Family Mortgage-Backed Securities (MBS) »

Fannie Mae creates MBS that represent beneficial ownership interests in a pool of mortgage loans secured by single-family (1-4 units) residential properties. An individual Single-Family MBS pool may hold mortgage loans that are either fixed-rate or adjustable-rate loans but will not hold both fixed-rate and adjustable-rate loans.

Multifamily Mortgage-Backed Securities (MBS) »

Fannie Mae creates MBS that represent beneficial ownership interests in a pool of mortgage loans secured by multifamily (5 or more units) residential properties. An individual Multifamily MBS pool may hold one or more mortgage loans that are either fixed-rate or adjustable-rate loans but will not hold both fixed-rate and adjustable-rate loans.

Structured Transactions and Megas »

Fannie Mae creates multiclass mortgage-backed securities including real estate mortgage investment conduits (REMICs) and stripped mortgage-backed securities (SMBS). REMICs permit an issuer to restructure cash flows on underlying mortgage assets into separately tradable securities. SMBS separate the principal and interest cash flows from underlying mortgage assets to create classes that pay only principal or only interest (known as principal only or interest only classes). Fannie Mae also creates and guarantees a single-class MBS known as a Fannie Mega® security or Mega. Megas are pass-through certificates backed by previously pooled Fannie Mae MBS with similar characteristics and/or other previously pooled Megas with similar characteristics.
