The scanner costs $6,900,000, Because of radiation contamination, it will actually be completely valueless in four years. You can lease it for $2,030,000 per year for four years. Assume that the tax rate is 21 percent. You can borrow at 8 percent before taxes. Assume that the scanner will be depreciated as three-year property under the MACRS depreciation. What is the NAL of the lease? (A negative answer should be Indlcated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
