Okla. Stat. tit. 70, § 70-5-161: Amendment of budget

A. The governing body may amend the budget to make supplemental

appropriations to any fund up to the amount of additional revenues

which are available for current expenses as shown by a fund balance

for the fund due to:

1. Revenues received or allocated from sources not anticipated

in the budget for that year;

2. Revenues received or allocated from anticipated sources but

in excess of the budget estimates therefor; or

3. Unexpended unencumbered cash balances on hand at the end of

the preceding fiscal year which had not been anticipated in the

budget. Any appropriation authorizing the creating of an

indebtedness shall be governed by the applicable provisions of

Article X of the Oklahoma Constitution.

B. If at any time during the budget year it appears probable

that revenues available will be insufficient to meet the amount

appropriated, or that due to unforeseen emergencies there

temporarily is insufficient money in a particular fund to meet the

requirements of appropriation for the fund, the governing body may

amend the budget to reduce one or more appropriations or it may

amend the budget to transfer money from one fund to another fund,

but no appropriation for debt service may be reduced and no

appropriation may be reduced by more than the amount of the

unencumbered and unexpended balance. No transfer shall be made from

the debt service fund to any other fund except as may be permitted

by the terms of the bond issue or by law.

C. Any budget amendment, as provided in this section,

authorizing supplemental appropriations or a decrease or change in

appropriation or funds shall be adopted by the governing body at a

meeting held in accordance with the Oklahoma Open Meeting Act and

filed with the clerk of the board of education, the county excise

board of each county in which the school district is located, and

the State Auditor and Inspector.
