Before the final transfer for a fiscal year is made, the Comptroller shall reconcile the estimated general funds revenues used in calculating the other transfers under this Section for that fiscal year with the actual general funds revenues for that fiscal year. The final transfer for the fiscal year shall be adjusted so that the total amount transferred under this Section for that fiscal year is equal to the percentage specified in subsection (b) or (c) of this Section, whichever is applicable, of the actual general funds revenues for that fiscal year. The actual general funds revenues for the fiscal year shall be calculated in a manner consistent with subsection (c) of Section 10 of this Act.
