Upon a determination by FHFA or a Bank that any director of the Bank no longer satisfies the eligibility requirements set forth in the Bank Act or this subpart, or has failed to comply with the reporting requirements of § 1261.12, the directorship shall immediately become vacant. Any director that is determined to have failed to comply with any of these requirements shall not continue to serve as a Bank director. Whenever a Bank makes such a determination, the Bank promptly shall notify the Bank director and FHFA in writing.
