(2) Payment amounts. For remaining aid payments due prior to July, moneys apportioned shall be determined based on preliminary aid data on file with the commissioner on December first, provided that such commissioner shall recompute such amounts designated for the month of June based on aid data on file with the commissioner as of May first.

Such sustaining advance payments due to school districts shall be, first, in the same proportion as such school district's share bears to the total moneys designated for payment in the month of April, second, as a share of the total moneys designated for May and last, if applicable, as a share of the total moneys designated for June to all such school districts pursuant to clauses (iv), (v), and (vi) of subparagraph two of this paragraph. The sustaining advance payment due shall be deducted first from a school district's designated amount for April, then from a school district's designated amount for May and finally from any moneys due in June.

(iii) Determining final payment for the state fiscal year. Prior to transmitting the March payment to the state comptroller, based on current year, base year and prior school year state aid payments made or scheduled to be made from the general support for public schools appropriations for the state fiscal year ending March thirty-first, the commissioner shall determine the extent to which the amount designated for June pursuant to clause (vi) of subparagraph two of this paragraph, as adjusted in accordance with clause (ii) of this subparagraph, net of any disallowances, would need to be advanced and paid on or before March thirty-first in order to use the remainder of such appropriations, excluding amounts assigned to the department of health pursuant to subdivision one of section thirty-six hundred nine-b of this article, on or before March thirty-first, or to the extent to which the amount designated for March would need to be proportionally reduced so as not to exceed such state fiscal year appropriations. The commissioner shall report the amount of money required to be advanced or deferred and the percent it represents of the June or March amounts, as the case may be, to the director of the budget, the chairperson of the senate finance committee and the chairperson of the assembly ways and means committee. To the extent that moneys are advanced or deferred pursuant to this paragraph, they shall be in the same proportion as each school district's share bears to the total of such June or March amount. Upon approval of the director of the budget, the commissioner shall transmit the schedule of any such partial June prepayments or such reduced March payments to the state comptroller. Any portion of the March payment deferred shall be added to the June payment; any portion of the June payment advanced shall be paid on or before March thirty-first.

The moneys apportioned to school districts for claims for current year aid for debt service on bond anticipation notes aidable in July following the current year and/or new bonds and capital notes aidable in July following the current year pursuant to subdivisions six and fourteen, if applicable, of section thirty-six hundred two of this part shall be paid on or before the last state business day of July immediately following the current school year, to the extent that moneys are owed to school districts pursuant to this section for the current year, net of any disallowances.

(vii) Deferred September payments. Any amounts payable to a school district pursuant to this section which exceeded one hundred percent of the respective amount set forth for such district as payable pursuant to this section in the school aid computer listing for the current school year shall be designated for payment for the month of September next following the close of the current school year.

Following each cycle payment, the commissioner of health shall report to the commissioner the aggregate amount of such federal medicaid payments to each school district. The commissioner shall recoup such amounts first, to the extent possible, from the specified payment, then by withholding any other moneys due the school district and finally by direct billing to any school district still owing moneys to the state. All moneys withheld or paid to the state on account of this paragraph shall be credited by the comptroller to the local assistance account for general support for public schools.
