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 $$4,600,000$ and would be depreciated straight$-$line to zero over three years. Because of radiation contamination, it will actually be completely valueless in three years. You can lease it for $$1,700,000$ per year for three years. Assume a $22$ percent tax bracket. You can borrow at $7$ percent before taxes. What is the NAL of the lease from the lessor's viewpoint?
