All moneys derived from the issuance of bonds under Sections 34-31 and 34-32, or from any tax levied pursuant to Section 34-57 when received by the city treasurer, as school treasurer, shall be set apart in the working cash fund. The moneys in such fund shall not be regarded as current assets available for appropriation and shall not be appropriated by the board in the annual school budget, but in order to provide moneys with which to meet ordinary and necessary disbursements for salaries and other educational purposes may be transferred, in whole or in part, to the educational purposes fund of the board and so disbursed therefrom (a) in anticipation of the collection of any taxes lawfully levied for educational purposes, (b) in anticipation of the receipt of moneys to be derived from the common school fund of the State and from State appropriations, or (c) in anticipation of such taxes, as by law now or hereafter enacted or amended, imposed by the General Assembly of the State of Illinois to replace revenue lost by units of local government and school districts as a result of the abolition of ad valorem personal property taxes, pursuant to Article IX, Section 5(c) of the Constitution of the State of Illinois. Moneys transferred to the educational purposes fund in anticipation of the collection of taxes shall be deemed to have been transferred in anticipation of the collection of that part of the taxes so levied or to be received which is in excess of the amount or amounts thereof required to pay any warrants, and the interest thereon, theretofore or thereafter issued under Sections 34-22 through 34-24, the amount estimated to be required to satisfy debt service and pension or retirement obligations as set forth in Section 12 of “An Act in relation to State revenue sharing with local government entities”, approved July 31, 1969, as amended. Such taxes levied for educational purposes when collected shall be applied first to the payment of any such warrants or notes and the interest thereon and the amount estimated to be required to satisfy debt service and pension or retirement obligations, as set forth in Section 12 of “An Act in relation to State revenue sharing with local government entities”, approved July 31, 1969, as amended, and then to the reimbursement of the working cash fund as hereinafter provided. Upon the receipt by the city treasurer, as school treasurer, of any taxes or other moneys, in anticipation of the collection or receipt whereof moneys of the working cash fund have been so transferred for disbursement, such fund shall immediately be reimbursed therefrom until the full amount so transferred has been re-transferred to said fund. If taxes in anticipation of the collection of which such transfers are made are not collected in sufficient amounts to effect a complete reimbursement of the working cash fund of the amounts transferred from the working cash fund to the educational purposes fund the deficiencies between the amounts thus transferred and the amounts repaid from collections shall be general obligations of the educational purposes fund until repaid either from taxes in anticipation of which transfers were made or from appropriations which may be made in annual school budgets of sums of money to apply on such general obligations or until repaid from both the taxes in anticipation of which such transfers were made and from appropriations which may be made in annual school budgets of sums of money to apply on such general obligations.
