The Baillat Corporation is considering the acquisition of a machine that costs $89,000 if bought today. Baillat can buy or lease the machine. If it buys the machine, the machine would be depreciated as a 3-year MACRS asset and is expected to have a salvage value of $2,000 at the end of the 4-year useful life. If leased, the lease payments are $21,000 each year for four years, payable at the beginning of each year. Use the MACRS rates as provided in Problem 1 and 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. a. Calculate the NPV of the lease assuming a marginal tax rate is 30% and a cost of capital of 10% b. Calculate the NPV of the lease assuming a marginal tax rate is 40% and a cost of capital of 10% c.
