You are evaluating two different silicon wafer milling machines. The Techron 1 costs $550,000, has a three-year life, and has pretax operating costs of $85,000 per year. The Techron II milling costs 650,000, has a five-year life, and has pretax operating costs of $97,000 per year. For both milling machines, use straight-line depreciation to zero over the projects life and assume a salvage value of $75,000. If your tax rate is 30 percent and your discount rate is 15 percent, compute the EAC for both machines. Which do you prefer? Why?
