In this section, “fund” means a youth welfare fund. There is a youth welfare fund in each facility of the Department of Juvenile Services. A fund shall be used for goods and services that benefit the general youth population in the facility. Each fund is a special continuing, nonlapsing fund that is not subject to § 7–302 of the State Finance and Procurement Article. Each fund consists of: profits derived from the sale of goods through the commissary operation and telephone and vending machine commissions for the facility; and subject to paragraph (3) of this subsection, money received from other sources. Money from the General Fund of the State may not be transferred by budget amendment or other manner to a fund. The Treasurer shall hold each fund separately, and the Comptroller shall account for each fund. Each fund is subject to an audit by the Office of Legislative Audits under § 2–1220 of the State Government Article. Each fund shall be invested and reinvested in the same manner as other State funds. Any investment earnings are not a part of the fund. The Comptroller shall pay out money from each fund as appropriated in the State budget.
