Suitable records shall be kept of each temporary advance.3. Moneys temporarily advanced pursuant to this section shall be repaid to the fund from which they were advanced as soon as available but in no event later than the close of the fiscal year in which the advance was made. If moneys from a fund which, if raised by taxes, special ad valorem levies or special assessments, would be raised from taxes, ad valorem levies or special assessments on a different base of properties than those for which taxes, ad valorem levies or special assessments would be raised for the fund to which the advance is made, the repayment shall include an amount reasonably estimated to be the additional amount that would have been earned on the investment of moneys in the fund making the advance had the advance not been made.
