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 $2.1 million in annual pretax cost savings. The system costs $9.4 million and will be depreciated straight-line to zero over its five-year life, after which it will be worthless. Wildcat's tax rate is 23 percent and the firm can borrow at 9 percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $2,176,667 per year. Lambert's policy is to require its lessees to make payments at the start of the year. What is the NAL for Wildcat?
