A revolving fund is established to be used to make loans and to pay expenses of the program. All appropriations and other receipts for the program must be placed in the fund, and all payments for program expenses must originate in the fund. Unappropriated surplus in the fund may be transferred through the appropriation process. (1990 L.M.C., ch. 17, § 1; 1997 L.M.C., ch. 6, § 1.)
