Case 3
The 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 subassemblies from a reliable outside supplier, who has quoted a unit price of $1 on a 7-year contract for a minimum of 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: | Per Unit | Direct Materials | $0.30 | Direct Labor | 0.35 | Variable Overhead | 0.10 | Fixed Overhead (including $0.10 depreciation and $0.10 for direct departmental fixed overhead) | 0.25 | Total Cost | $1.00 | | |
The 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 has summarized her position as follows: The increase in machine speeds will reduce direct labor and variable overhead by $0.35 per unit. Consider last year’s experience of one of your major competitors with identical equipment. It produced 100,000 units under operating conditions very comparable to yours and showed the following unit costs.
| Per Unit | Direct Materials | $0.30 | Direct Labor | 0.05 | Variable Overhead | 0.05 | Fixed Overhead (including $0.10 depreciation and $0.10 for direct departmental fixed overhead) | 0.40 | Total Cost | $0.80 |
For purposes of this case, assume that any idle facilities cannot be put to alternative use. Also assume that $0.05 of the old Rohr unit cost is allocated fixed overhead that will be unaffected by the decision.
