You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner $($leasing is a common practice with expensive, high$-$tech equipment$).$ The scanner costs $$4\mathrm{.}3$ million and would be depreciated straight$-$line to zero over four years. Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $$1\mathrm{.}275$ million per year for four years. Assume that the tax rate is $21$ percent. You can borrow at $8$ percent before taxes.

Calculate the NAL.
