SCENARIO ANALYSIS Your firm, Agrico Products, is considering a tractor that would have a cost of $37,000, would increase pretax operating cash flows before taking account of depreciation by $12,000 per year, and would be depreciated on a straight-line basis to zero over 5 years at the rate of $7,400 per year beginning the first year. (Thus, annual cash flows would be $12,000 before taxes plus the tax savings that result from $7,400 of depreciation.) The managers disagree about whether the tractor would last 5 years. The controller insists that she knows of tractors that have lasted only 4 years. The treasurer agrees with the controller, but he argues that most tractors do give 5 years of service. The service manager then states that some last for as long as 8 years Assume that if the tractor only lasts 4 years, then the firm would receive a tax credit in Year 4 because the tractor's salvage value at that time is less than its book value. Under this scenario, the firm would not take depreciation expense in Year 5 Given this discussion, the CFO asks you to prepare a scenario analysis to determine the importance of the tractor's life on the NPV sea 4096 marginal federal-plus-state tax rate, a zero salvage value, and a 8% WACC. Assuming each of the indicated ves has the same probability of occurring (probability 1/3), what is the tractor's expected NPV? Round your answers to two decimal places. Do not round intermediate calculations. Negative amount should be indicated by a minus sign. a. Tractor's NPV if actual life is 5 years. $3565.93 b. Tractor's NPV if actual life is 4 years. c.Tractor's NPV if actual life is 8 years. d. Tractor's expected NPV
