The Federal Housing Finance Agency (FHFA) is amending its regulations by relocating to the FHFA chapter of the Code of Federal Regulations (CFR) a Federal Housing Finance Board (Finance Board) regulation relating to procedures under which the Federal Home Loan Banks (Banks) and the Office of Finance (OF) may request waivers, approvals, no-action letters, and regulatory interpretations. The final rule modifies these regulations to make them also applicable to the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation (collectively, Enterprises) and repeals provisions relating to the procedures for requesting case-by-case determinations. The final rule also relocates a definition to the general definitions section of the FHFA regulations.
