- 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.
