4. Dhe Arrende Corporation is considering the acquisition of a machine that costs $73,000 if bought today. The company can buy or lease the machine. If it buys the machine, the machine would be depreciated using the straight-line method, depreciating the full asset cost over five years, and is expected to have a salvage value of $2,000 at the end of the 5-year useful life. If leased, the lease payments are $17,500 each year for four years, payable at the beginning of each year. Arrende's marginal tax rate is 38% and the appropriate cost of capital is 10%. Assume that the lease is a net lease, that any tax benefits are realized in the year of the expense, and that there is no investment tax credit. 9. Calculate the depreciation for each year in the case of the purchase of this machine b. Calculate the direct cash flows from leasing initially and for each of the five years c. Calculate the adjusted discount rate d. Calculate the NPV of the lease e. Calculate the amortization of the equivalent loan
