Any school district may abate its working cash fund at any time, upon the adoption of a resolution so providing, and direct the transfer at any time of moneys in that fund to any fund or funds of the district most in need of the money, provided that the district maintains an amount to the credit of the working cash fund, including taxes levied pursuant to Section 20-3 and not yet collected and amounts transferred pursuant to Section 20-4 and to be reimbursed to the working cash fund, at least equal to 0.05% of the then current value, as equalized or assessed by the Department of Revenue, of the taxable property in the district. If necessary to effectuate the abatement, any outstanding loans to other funds of the district may be paid or become payable to the fund or funds to which the abatement is made. Any abatement of a school district's working cash fund prior to the effective date of this amendatory Act of the 96th General Assembly that would have complied with the provisions of this Section is hereby validated.
