Mont. Code § 20-9-132
At the final budget meeting of the trustees, the trustees may make any changes or corrections they may consider necessary or proper in any item or amount of the budget either by eliminating the item or amount or by increasing or reducing the amount of any item. When it appears to the trustees that the amount proposed to be expended for any item of the final budget is in excess of the amount actually required to be expended for the item, the trustees shall reduce the amount to the amount actually required to be expended and shall enter in its minutes the reasons for the reduction. If any appropriation item of the final budget provides for the payment of wages or salary to more than one person, the district shall attach to the budget a separate listing of each position of employment, with the budgeted amount of compensation for each position.
