Money shall be transferred from the working cash fund to the general corporate fund only upon the authority of the corporate authorities who, from time to time by a separate ordinance, shall direct the municipal treasurer to make a transfer of such sums as may be required for the purposes authorized in this Division 6. That ordinance shall set forth (1) the taxes in anticipation of the collection of which the transfer is to be made and from which the working cash fund is to be reimbursed, (2) the entire amount of taxes extended, or which the corporate authorities estimate will be extended, or received, for any particular year in anticipation of the collection of all or part of which the transfer is to be made, (3) the aggregate amount of warrants or notes theretofore issued in anticipation of the collection of these taxes together with the amount of the interest which has accrued and which, the corporate authorities estimate, will accrue thereon, (4) the aggregate amount of receipts from taxes imposed 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, which the corporate authorities estimate will be set aside for the payment of the proportionate amount of debt service and pension or retirement obligations, as required by Section 12 of "An Act in relation to State Revenue Sharing with local government entities", approved July 31, 1969, as amended, and (5) the aggregate amount of money theretofore transferred from the working cash fund to the general corporate fund in anticipation of the collection of such taxes. The amount which that ordinance shall direct the treasurer so to transfer in anticipation of the collection of taxes levied or to be received for any particular year, together with the aggregate amount of such tax anticipation warrants or notes theretofore drawn against such taxes and the amount of the interest accrued and estimated to accrue thereon, 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 the aggregate amount of such transfers theretofore made in anticipation of the collection of these taxes, shall not exceed 90% of the actual or estimated amount of such taxes extended or to be extended or to be received as set forth in that ordinance.
If money is available in the working cash fund, it shall be transferred to the general corporate fund and disbursed for the payment of salaries and other corporate expenses so as to avoid, whenever possible, the issuance of tax anticipation warrants or notes.
