How are six of the nine director positions for tht boards of each federal district bank filled?

Six of the nine director positions for the boards of each Federal Reserve Bank are filled by member banks in the district. These member banks elect three directors from their ranks, while the Federal Reserve Board of Governors in Washington, D.C., appoints three additional directors who are not affiliated with the banking industry. This structure aims to ensure a balance of perspectives and interests in the governance of each Federal Reserve Bank.
