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 $1.9 million in annual pretax cost savings. The system costs $8.6 million and will be depreciated straight-line to zero over five years. Wildcat's tax rate is 34 percent, and the firm can borrow at 8 percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $2.15 million per year. Lambert's policy is to require its lessees to make payments at the start of the year. Many lessors require a security deposit in the form of a cash payment or other pledged collateral. Suppose Lambert requires Wildcat to pay a $800,000 security deposit at the inception of the lease. Calculate the NAL with the security deposit. (Negative amount should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) NAL $
