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 $3.7 million in annual pretax cost savings. The system costs $8.8 million and will be depreciated straight-line to zero over its five-year life, after which it will be worthless. Wildcats tax rate is 22 percent and the firm can borrow at 9 percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $1,970,000 per year. Lamberts policy is to require its lessees to make payments at the start of the year. Suppose Lambert requires Wildcat to pay a $900,000 security deposit at the inception of the lease.

Calculate the NAL with the security deposit.
