MPF Xtra Updates – FNMA LL-2026-04

Fannie Mae published Lender Letter LL-2026-04 issues a governance framework for use of artificial intelligence and/or machine learning in origination and/or servicing practices which will apply to all PFIs/Servicers delivering or servicing MPF Xtra loans effective 120 from publication of LL-2026-04 (i.e. August 6, 2026).

PFIs/Servicers using AI/ML in connection with the origination or servicing of MPF Xtra loans must ensure compliance with applicable laws, the PFI Agreement, the MPF Guides and the guidance in LL-2026-04, including guidance related to:

• Having policies and procedures regarding the development, implementation, use and maintenance of any AI/ML system it utilizes, and the measuring and managing of AI/ML risks;
• Complying with the requirements in the Fannie Mae Information Security and Business Resiliency Supplement; and
• Managing risks and appropriate governance of subcontractor and vendor use of AI/ML that is no less protective of these requirements.

Updates to the MPF Guides incorporating these requirements will be published at a later date.

To gain a full understanding of the requirements, PFIs/Servicers should review the entire Fannie Mae Announcement and any applicable Fannie Mae Selling Guide chapters, forms, or exhibits noted in the announcements.
