Cost of materials (millions of dollars). This includes the total delivered cost of raw materials, parts, and supplies put into production or used for repair and manteinance, along with purchased electric energy and fuels consumed for heat and power, and contract work done by others for the plant. This excludes the costs of services used, overhead costs, or expenditures related to plant expansion. Because MATCOST includes energy spending, to calculate spending on non-energy materials one must use (MATCOST-ENERGY).
