The Wildcat Oil Company is trying to decide whether to lease or buy a new computer- assisted drilling system for its oil exploration business. Management has decided that it must use the system to stay competitive; it will provide $3.1 million in annual pretax cost savings. The system costs $7.7 million and will be depreciated straight-line to zero over 5 years. Wildcat's tax rate is 22 percent, and the firm can borrow at 7 percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $1.73 million per year. Lambert's policy is to require its lessees to make payments at the start of the year. a. What is the NAL for Wildcat? (A negative answer should be indicated by a minus sign.
