In this section, “Fund” means the National Guard State Active Duty Mobilization Fund. There is a National Guard State Active Duty Mobilization Fund in the Office of the Adjutant General within the Department. The purpose of the Fund is to pay for personnel and equipment for State active duty mobilization of the National Guard, as ordered by the Governor. The Adjutant General shall administer the Fund. The Fund is a special, nonlapsing fund that is not subject to § 7–302 of the State Finance and Procurement Article. The State Treasurer shall hold the Fund separately, and the Comptroller shall account for the Fund. The Fund consists of: money appropriated in the State budget to the Fund; and any other money from any other source accepted for the benefit of the Fund. The Fund may be used only for the expenses of and to support the operations of the National Guard in State active duty status. The State Treasurer shall invest the money of the Fund in the same manner as other State money may be invested. Any investment earnings of the Fund shall be credited to the General Fund of the State. Expenditures from the Fund may be made only in accordance with the State budget. Money expended from the Fund for State active duty mobilization of the National Guard is supplemental to and is not intended to take the place of funding that otherwise would be appropriated for State active duty mobilization of the National Guard. Money expended from the Fund shall be replenished in a timely manner to maintain the operational effectiveness of future State active duty mobilizations of the National Guard.
