Your company has purchased equipment (for $50,000) that will reduce materials and labor costs by $16,000 each year for N years. After N years, there will be no further need for the machine, and because the machine is specially designed, it will have no MV at any time. The IRS, however, has ruled that you must depreciate the equipment on a SL basis with a tax life of four years. If the effective income tax rate is 19%, what is the minimum number of years your firm must operate the equipment to earn 10% per year after taxes on its investment?
