Ind. Code § 4-10-18-9

Sec. 9. If the total state general fund revenues for a state fiscal year, in which a transfer into the fund is made, are less than the level estimated in the budget report prepared in accord with IC 4-12-1-12(a) or IC 4-12-1-12(c) and the shortfall cannot be attributed to a statutory change in the tax rate, the tax base, the fee schedules, or the revenue sources from which the general fund revenue estimate was made, the budget director, with the approval of the governor, may transfer from the fund to the state general fund an amount that may not exceed the amount that was transferred into the fund during that state fiscal year.
