Any class of school district may execute and deliver in evidence thereof their promissory notes which they are hereby authorized and empowered to make and negotiate, bearing a rate of interest set by the school board and maturing not more than two school fiscal years from the date thereof. Such notes, before they are negotiated, shall be presented to the treasurer of the school district and registered by him or her and shall be payable out of the funds collected by such school district in the order of their registry after the payment of prior registered warrants but prior to the payment of any warrant subsequently registered, except that if both warrants and notes are registered, the total of such registered notes and warrants shall not exceed one hundred percent of the unexpended balance of the total anticipated receipts of the general fund, special building fund, bond fund, or qualified capital purpose undertaking fund of such district for the current school fiscal year and the following school fiscal year. For the purpose of making such calculation, such total anticipated receipts shall not include any anticipated receipts against which the school district has borrowed and issued notes pursuant to this section in either the current or the immediately preceding school fiscal year.
