You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner (leasing is a very common practice with expensive, high-tech equipment). The scanner costs $6,200,000, and it would be depreciated straight-line to zero over four years. Because of radiation contamination, it actually will be completely valueless in four years. You can lease it for $1,810,000 per year for four years. Assume that your company does not anticipate paying taxes for the next several years. You can borrow at 7 percent before taxes. What is the NAL of the lease? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
