WASHINGTON, DC – Fannie Mae (FNMA/OTC) today announced the launch of DUS Disclose, a new MBS disclosure website that will enhance the transparency and increase the data available for Multifamily securities in alignment with the industry.

"We have worked closely with industry partners over the past six months in preparation of the site's deployment and have received positive feedback," said Dan Dresser, Vice President for Multifamily Capital Markets, Trading, and Credit Pricing. "The new DUS Disclosure system ensures that our investors have the data they need to better analyze our multifamily securities."

The new DUS Disclose website replaces the Multifamily Securities Locator Service (MFSLS) and provides a user-friendly interface with more comprehensive data, enhanced disclosures, and the ability to download expanded security, loan, and property level information.

Additional details on the transition from MFSLS to DUS Disclose can be found in the announcement on the Mortgage-Backed Securities web page.
