National Industries is a diversified corporation with separate operating divisions. Each division's performance is evaluated based on its total dollar profits and return on division investment. The WindAir division manufactures and sells air conditioners. The coming year's budgeted income statement, based on a sales volume of 15,000 units, is as follows: WINDAIR DIVISION Budgeted Income Statement For the Fiscal Year Per Unit Total (in thousands) Sales revenue $400 $6,000 Manufacturing costs Compressor 70 1,050 Other raw materials 37 555 Direct labour 30 450 Variable overhead 45 675 32 480 214 3,210 2,790 186 Fixed overhead Total manufacturing costs Gross margin Operating expenses Variable selling Fixed selling Fixed administration Total operating expenses 18 270 19 285 38 570 75 1,125 Net income before taxes $111 $1,665 WindAir's manager believes that sales can be increased if it reduces the unit selling price of the air conditioners. A market research study conducted by an independent firm at the manager's request indicates that a 5% reduction ($20) in the selling price would increase the sales volume by 16%, or 2,400 units. WindAir has enough production capacity to manage this increased volume with no increase in fixed costs. Currently, WindAir uses a compressor in its units that it purchases from an outside supplier at a cost of $70 per compressor. The manager of WindAir has approached the manager of National Industries' compressor division about the sale of a compressor unit to WindAir. The compressor division currently manufactures and sells to outside firms a unit that is similar to the compressor used by WindAir. The specifications of the WindAir compressor are slightly different and would reduce the compressor division's raw materials cost by $1.50 per unit. In addition, the compressor division would not incur any variable selling costs for the units sold to WindAir. The manager of WindAir wants all of the compressors it uses to come from one supplier and has offered to pay $50 for each compressor unit. The compressor division has the capacity to produce 75,000 units. The coming year's budgeted income statement for the compressor division, which follows, is based on a sales volume of 64,000 units without considering WindAir's proposal.
