Monies may be transferred from the county working cash fund to the general corporate fund or special tax funds only upon the authority of the county board, which shall from time to time by separate resolution direct the county treasurer to make transfers of such sums as may be required for the purposes authorized by this Division. Every such resolution must set forth (a) the taxes or other monies in anticipation of the collection or receipt of which such transfer is to be made and from which the working cash fund is to be reimbursed, (b) the entire amount of taxes extended or which the county board estimates will be extended or received, for any year in anticipation of the collection of all or part of which such transfer is to be made, (c) the aggregate amount of warrants or notes theretofore issued in anticipation of the collection of such taxes together with the amount of interest accrued or which the county board estimates will accrue, thereon (d) the aggregate amount of notes theretofore issued in anticipation of the collection of such taxes, together with the amount of the interest accrued or which the county board estimates will accrue thereon, (e) the amount of monies which the county board estimates will be earned by the county clerk and the county collector, respectively, as fees or commissions for extending or collecting taxes for any year, in anticipation of the receipt of all or part of which such transfer is to be made, (f) 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 (g) the aggregate amount of monies theretofore transferred from the working cash fund to the general corporate fund and special tax funds in anticipation of the collection of such taxes or the receipt of such other monies to be derived from fees or commissions.
The amount which any such resolution directs the county treasurer to transfer, in anticipation of the collection of taxes levied or to be received for any year, together with (a) the aggregate amount of such anticipation tax warrants and notes theretofore drawn against such taxes (b) the amount of the interest accrued or estimated to accrue on such warrants and notes, (c) 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 (d) the aggregate amount of such transfers theretofore made in anticipation of the collection of such taxes, may 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 the resolution. The amount which any such resolution directs the county treasurer so to transfer, in anticipation of the receipt of any monies to be derived from fees or commissions, together with the aggregate amount theretofore transferred in anticipation of the receipt of any such monies, may not exceed the total amount which it is so estimated will be received from those sources. To the extent that at any time monies are available in the working cash fund they 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 anticipation tax warrants or notes.
Temporarily idle monies in the working cash fund may be invested as directed by the county board, and the interest earnings on such investments may, at the option of the board, be either transferred permanently to the general corporate or special tax funds or both or be allowed to remain in the working cash fund. If such interest earnings remain in the working cash fund they will serve to increase the balance of the working cash fund available for loans.
