Miss. Code Ann. § 37-47-13: Certificates of credit.

When the amounts of the annual grants to school districts have been computed as provided in Section 37-47-9, the commission shall credit each such school district with the amount of the annual grant to which it is entitled and shall issue to each such school district a certificate of credit for the amount of such annual grant. All such certificates of credit shall be signed by the chairman of the commission and countersigned by the executive secretary thereof. Such certificates shall constitute an indebtedness of the State of Mississippi but shall be non-transferable and non-negotiable and shall bear no interest. All such certificates so issued shall be held and retained by the school district to which same are issued until the expenditure of the funds to the credit of such school district shall be approved by the commission as is otherwise provided in this chapter. Such certificates shall be surrendered to the commission at the time the funds to which the school district is entitled are withdrawn from the public school building fund and deposited to the credit of the school district entitled thereto.
