Mont. Code Ann. § 20-9-348

The apportionment of state equalization aid shall be the second source of revenue in calculating the financing of the elementary district BASE funding program and the high school district BASE funding program. In order to allow for the estimation of the amount of money to be realized from this source of revenue when the county superintendent is estimating the general fund budget revenues, the county superintendent shall consider that the state BASE funding program revenues and county equalization moneys, together, will be capable of financing 100% of the BASE funding program.
