A corporation is considering purchasing a machine that has an expected eight-year life and will generate for the firm $11,000 per year in net operating income before taxes. The machine will be depreciated using the straight-line method to its anticipated salvage value of $12,000. The firm has a 34% marginal tax rate and the required return for this project is 12% p.a. If the machine costs $60,000, should it be purchased?
