All disbursements from the petty cash accounts shall be made in the same manner as other disbursements from the school activity fund, except no disbursement shall be made from a petty cash account unless a prenumbered, dated receipt be obtained and signed by the person receiving payment. A school board may designate a petty cash custodian to countersign petty cash checks in place of the activity fund custodian. The school activity fund custodian shall file claims against the general fund of the school district for reimbursement of a petty cash account whenever the need shall arise. Such claims shall be itemized in the same manner as other claims filed against the general fund and shall have attached thereto the receipts covering each of the expenditures claimed for reimbursement. The total of a petty cash account balance and the receipts on hand awaiting reimbursement should equal at all times the authorized amount of a petty cash account.
None of the provisions pertaining to a petty cash account shall be construed to authorize the use of one (1) fiscal year's fund to pay obligations of another fiscal year. Any remaining balance in each petty cash account shall be transferred to the general fund on or before June 30 of each year.
