The Wildcat Oil Company is trying to decide whether to lease or buy a new computerassisted drilling system for its oil exploration business. Management has decided that it must use the system to stay competitive; it will provide $2.8 million in annual pretax cost savings. The system costs $8.78 million and will be depreciated straight-line to zero over five years. Wildcat’s tax rate is 21 percent, and the firm can borrow at 7 percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $1.95 million per year. Lambert’s policy is to require its lessees to make payments at the start of the year. Return to the case of the diagnostic scanner used in Problems 1 through 6. Suppose the entire $4.3 million purchase price of the scanner is borrowed. The rate on the loan is 8 percent, and the loan will be repaid in equal installments. Create a lease-versus-buy analysis that explicitly incorporates the loan payments. Show that the NPV of leasing instead of buying is not changed from what it was in Problem 1. Why is this so?
