Fannie Mae to Provide Single-Family MBS Loan-Level Disclosure in 2012

Beginning in the first quarter of 2012, Fannie Mae will start disclosing loan-level data for its Single-Family MBS. The first release will provide at issuance loan-level data for newly issued Single-Family MBS. Subsequent releases aim to enhance the at issuance file by including additional data elements and to provide updated loan-level data on a monthly basis. Release dates for each phase will be announced closer to their implementation date. 

Release summary:

The first release will provide:

  • Downloadable loan-level data files for newly issued Single-Family MBS, published in the New Issues Statistics Tab in PoolTalk®

In subsequent releases, we expect to be able to provide:

  • Additional data elements in the loan-level at issuance file
  • Monthly updates to the loan-level data

The file format for the initial loan-level disclosure is provided for reference.

These loan-level data files will be hosted on an enhanced version of PoolTalk, our online disclosure application. The roll-out of our enhanced PoolTalk will coincide with the release of the at issuance loan-level disclosure in the first quarter of 2012.  The new version of PoolTalk will enhance the user experience for accessing disclosure data on the Fannie Mae website by:

  • allowing users to view data on a specific pool or deal through an easy to use tabular interface,

  • providing a portfolio capability whereby registered users will be able to view and monitor data for their selected securities at a glance, and

  • consolidating numerous files and documents into one location.  

Users will be able to access the following files and documents within the new version of PoolTalk:
