Fannie Mae Releases New Mission Index Criteria Attribution (MICA) Resources

Today, Fannie Mae released version 1.0 of the Mission Index Criteria Attribution (MICA), a social impact estimation methodology for our Single-Family mortgage-backed securities. The MICA disclosure supplement and accompanying tool provide impact investors with enhanced insights into the representation of specific populations of Mission borrowers in their portfolios.

The disclosure supplement and CUSIP mapping tool are available in PoolTalk®, in addition to an Excel-based tool on our website that automates the estimation methodology. Additional resources including a methodology overview, user guide, and webinar replay are also available on our website.

The initial release of the MICA v1.0 disclosure supplement helps to facilitate market feedback to support the development of the MICA v1.1 disclosure supplement, which we anticipate publishing in Q1 2025 and updating regularly thereafter. The initial release contains Level 1 securities only; Level 2 and 3 securities are contemplated as future enhancements.

We welcome feedback and questions from market participants, please contact the Fannie Mae Investor Help Line at 1-800-232-6643 or by email.
