Each regional Bank's board consists of nine members. Members are broken down into three classes: A, B, and C. There are three board members in each class. Class A members are chosen by the regional Bank's shareholders, and are intended to represent member banks' interests. Member banks are divided into three categories: large, medium, and small. Each category elects one of the three class A board members. Class B board members are also nominated by the region's member banks, but class B board members are supposed to represent the interests of the public. Lastly, class C board members are appointed by the board of governors, and are also intended to represent the interests of the public.
