Key Requirements

- Establish comprehensive AI/ML governance policies and procedures within 66 days - Implement annual review process for AI/ML policies to ensure compliance and best practices - Train appropriate personnel on AI/ML governance framework and responsibilities - Incorporate trustworthy and ethical AI/ML characteristics into governance framework - Establish vendor and subcontractor AI/ML oversight with equivalent protective requirements - Comply with Fannie Mae Information Security and Business Resiliency Supplement requirements - Prepare capability to disclose AI/ML usage details, purposes, and safeguards upon Fannie Mae request

Scoring Rationale

This guidance establishes the first comprehensive AI/ML governance framework for Fannie Mae seller/servicers, requiring significant operational changes including new policies, training, vendor oversight, and governance structures. While not enterprise-restructuring (score 5), it requires cross-functional coordination and dedicated program implementation. The 120-day implementation timeline and broad scope across origination and servicing operations drives moderate to high impact scores across most categories.
