(110 ILCS 805/7-9) (from Ch. 122, par. 107-9)
    Sec. 7-9. The budget shall set forth estimates, by classes, of all current assets and liabilities of each fund of the board as of the beginning of the fiscal year, and the amounts of those assets estimated to be available for appropriation in that year, either for expenditures or charges to be made or incurred during that year or for liabilities unpaid at the beginning thereof. Estimates of taxes to be received from the levies of prior years shall be net, after deducting amounts estimated to be sufficient to cover the loss and cost of collecting those taxes and also deferred collections thereof and abatements in the amount of those taxes extended or to be extended upon the collectors' books.
    Estimates of the liabilities of the respective funds shall include:
        1. all final judgments, including accrued interest
    
thereon, entered against the board and unpaid at the beginning of that fiscal year;
        2. the principal of all tax anticipation warrants and
    
all temporary loans and all accrued interest thereon unpaid at the beginning of that fiscal year;
        3. any amount for which the board is required under
    
this Act to reimburse the working cash fund from the educational fund and operations and maintenance fund; and
        4. the amount of all accounts payable including
    
estimates of audited vouchers, participation certificates, interfund loans and purchase orders payable.
    The budget shall also set forth detailed estimates of all taxes to be levied for that year and of all current revenues to be derived from sources other than taxes, including State and Federal contributions, rents, fees, perquisites, and all other types of revenue, which will be applicable to expenditures or charges to be made or incurred during that year.
    No estimate of taxes to be levied during the fiscal year for educational purposes and operations and maintenance of facilities purposes may exceed a sum equivalent to the product of the value of the taxable property in the district, as ascertained by the last assessment for State and county taxes previous to the passage of the budget, multiplied by the maximum per cent or rate of tax which the corporate authorities of the city are authorized by law to levy for the current fiscal year for those purposes.
    All these estimates shall be so segregated and classified as to funds and in such other manner as to give effect to the requirements of law relating to the respective purposes to which the assets and taxes and other current revenues are applicable, so that no expenditure will be authorized or made for any purpose in excess of the money lawfully available therefor.
    The several estimates of assets, liabilities and expenditure requirements required or authorized to be made by this Section and by Section 7-10 shall be made on the basis of information known to the board at the time of the passage of the annual budget and are not invalidated or otherwise subject to attack merely because after that time additional information is known to or could be discovered by the board that would require a different estimate or because the board might have amended these estimates under Section 7-12.
