PROBLEM 12-24 Make or Buy Analysis LO3] "In my opinion, we ought to stop making our own drums and accept that outside supplier's offer" said Wim Niewindt, managing director of Antilles Refining, N.V., of Aruba. "At a price of 18 florins per drum, we would be paying 5 florins less than it costs us to manufacture the drums in our own plant. (The currency in Aruba is the florin, denoted below by fl.) Because we use 60,000 drums a year, that would be an annual cost savings of 300,000 florins." Antilles Refining's present cost to manufacture one drum is given below (based on 60,000 drums per year): Direct materials... Direct labor Variable overhead Fixed overhead (12.80 general company ...10.35 6.00 1.50 overhead. 60 depreciation and, 10.75 supervision). Total cost per drum 5.15 23.00 Relevant Costs for Decision Making 525 A decision about whether to make or buy the drums is especially important at this time because the equipment being used to make the drums is completely worn out and must be replaced. The choices facing the company are: Alternative 1: Rent new equipment and continue to make the drums. The equipment would be rented for 1135,000 per year Altemative 2: Purchase the drums from an outside supplier at fl18 per drum. The new equipment would be more efficient than the equipment that Antilles Refining has been using and, according to the manufacturer, would reduce direct labor and variable overhead costs by 30% The old equipment has no resale value. Supervision cost (1145.000 per year) and direct materials cost per drum would not be affected by the new equipment. The new equipment's capacity would be 90,000 drums per year The company's total general company overhead would be unaffected by this decision. Required: I. To assist the managing director in making a decision, prepare an analysis showing the total cost and 2. Would your recommendation in (1) above be the same if the company's needs were: (a) 75,000 drums 3. What other factors would you recommend that the company consider before making a decision? the cost per drum for each of the two alternatives given above. Assume that 60,000 drums are needed each year. Which course of action would you recommend to the managing director? per year or (b) 90,000 drums per year? Show computations to support your answer, with costs presented on both a total and a per unit basis
