Actually I think I'm wrong on this one.

Appointments to the Board
The seven members of the Board of Governors are appointed by the President and confirmed by the Senate to serve 14-year terms of office. Members may serve only one full term, but a member who has been appointed to complete an unexpired term may be reappointed to a full term. The President designates, and the Senate confirms, two members of the Board to be Chairman and Vice Chairman, for four-year terms.
