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 $$1\mathrm{.}8$ million in annual pretax cost savings. The system costs $$7\mathrm{.}6$ million and will be depreciated straight$-$line to zero over four years. Wildcat's tax rate is $38$ percent, and the firm can borrow at $9$ percent. Lambert Leasing Company has offered to lease the drilling equipment to Wildcat for payments of $$1,600,000$ 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 $$230,000$ security deposit at the inception of the lease. What is the NAL with the security deposit?
