The Board of Governors of the Federal Reserve System issued CA 18-8 to update interagency examination procedures for Regulation CC and the Expedited Funds Availability Act. These revised procedures supersede CA Letter 04-9 and incorporate amendments effective July 1, 2018, including extended coverage to American Samoa, the Commonwealth of the Northern Mariana Islands, and Guam. The guidance applies to all institutions supervised by the Federal Reserve and removes outdated examples and examination procedures to align with current regulatory requirements.
