A firm is concerned about the condition of some of its plant machinery. Bill James, a newly hired engineer, reviewed the situation and identified five feasible, mutually exclusive alternatives.

Alternative A: Spend $44,000 now repairing various items. The $44,000 can be charged as a current operating expense (rather than capitalized) and deducted from other taxable income immediately. A These repairs will keep the plant functioning for 7 years with current operating costs.

Alternative B: Spend $49,000 to buy general-purpose equipment. Depreciation would be 5-year MACRS. The equipment has no salvage value after 7 years. The new equipment will reduce annual operating costs by $7000.

Alternative C: Spend $56,000 to buy new specialized equipment. This equipment would be depreciated by 5-year MACRS. This equipment would reduce annual operating costs by $12,000. It will have no salvage value.

Alternative D: This is the "do nothing" alternative, with annual operating costs $8000 above the present level.

This profitable firm pays 28% corporate income taxes and uses a 10% after-tax rate of return. Which alternative should the firm adopt?
