(a) For the school year 1977-1978 through the school year 1985-1986, the Commonwealth shall pay to intermediate units an amount equal to the product of the Statewide median actual instruction expense per weighted average daily membership (WADM) by the product of forty-five one-hundredths of one percent (0.45%) and the average daily membership of all school districts in the Commonwealth, as determined by the Secretary of Education according to the latest available actual data. For the school year 1986-1987 and each school year thereafter, the Commonwealth shall pay to intermediate units an amount equal to the product of the Statewide median actual instruction expense per weighted average daily membership (WADM) by the product of forty one-hundredths of one percent (0.40%) and the average daily membership of all school districts in the Commonwealth, as determined by the Secretary of Education according to the latest available data.

(b) For the school year 1977-1978 and each school year thereafter, each intermediate unit shall be paid the amount it received from the Commonwealth for the 1976-1977 school year.

(c) In addition to the amount paid to each intermediate unit under subsection (b), each intermediate unit shall be paid for the 1977-1978 school year through the 1985-1986 school year an amount determined by subtracting the total payments under subsection (b) from the total allocation under subsection (a) divided by the average daily membership (ADM) of all school districts in the Commonwealth multiplied by the average daily membership (ADM) of all component school districts in the intermediate unit, as determined by the Secretary of Education according to the latest actual data available. In addition to the amount paid to each intermediate unit under subsection (b), each intermediate unit shall be paid for the 1986-1987 school year through the 1995-1996 school year an amount determined by subtracting the total payments under subsection (b) from the total allocation under subsection (a). One-half of that amount shall be divided by twenty-nine and the amount derived paid to each intermediate unit. The remaining one-half shall be divided by the average daily membership (ADM) of all school districts in the Commonwealth and multiplied by the average daily membership (ADM) of all component school districts in the intermediate unit, as determined by the Secretary of Education according to the latest actual available data, and the amount derived paid to each intermediate unit.

During the 1998-1999 school year, however, no intermediate unit shall receive less payment under this subsection than the amount of the payments the intermediate unit received under subsection (g) during the 1997-1998 school year.
