6-66 Make or BuyThe Rohr Company’s Old Equipment for making subassemblies is worn out. The company is considering two courses of action: (a) completely replacing the old equipment with new equipment or (b) buying assemblies from a reliable outside supplier, who has quoted a unit Price of $1 on a seven-year contract for a mínimum pg 50,000 units per year.Production was 60,000 units in each of the past 2 years. Future needs for the next 7 years are not expected to fluctuate beyond 50,000 to 70,000 units per year. Cost records for the past 2 years reveal the following unit costs of manufacturing the subassembly:Direct Materials$.30Direct Labor .05 .10Fixed Overhead (including $.10 depreciation and $.10 for direct departamental fixed overhead) .25$1.00The new equipment will cost $188,000 cash, will last 7 years, and will have a disposal value of $20,000. The current disposal value of the old equipment is $10,000.The sales representative for the new equipment is summarized her position as follows: The increase in machine speeds will reduce direct labor and variable overhead by $.35 per unit. Consider last year’s experience of one of your major competitors with identical equipment. They produced 100,000 units under operating conditions very comparable to yours and showed the following unit costs.Direct Materials$.30Direct Labor .05Variable Overhead .05Fixed Overhead, including depreciation of $.24 .40Total $.80For purpose of this case, asume that any idle facilities cannot be put to alternative use. Also asume that $.05 of the old Rohr unit cost is allocated fixed overhead that will be unaffected by the decisión1.The president asks you to compare the alternatives on a total-annual-cost basis and on a per unit basis for anual needs of 60,000 units. Which alternative seems more attractive?2.Would you answer to number 1 change if the needs were 50,000 units? 70,000 units? At what volumen level would Rohr be indifferent between making and buying subassemblies? Show your computations.
