Executive director – The executive leader of an agency.

Reimbursement – Money paid to compensate travelers for money spent while traveling on official business.

State mileage rate – A calculated mileage rate rounded to the nearest cent, based on the average of 2 GSA rates: (1) the rate labeled, “If use of a privately owned automobile is authorized or if no government-furnished automobile is available” and (2) the rate labeled “if a government-furnished automobile is available.” These rates are listed on the U.S. General Services Administration website.
