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 $5,000,000. Because of radiation contamination, it actually will be completely valueless in four years. You can lease it for $1,490,000 per year for four years. Assume that the tax rate is 22 percent. You can borrow at 8 percent before taxes. Assume that the scanner will be depreciated as three-year property under MACRS. Use Table 10.7. Check my a. What is the NAL of the lease? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) b. Should you lease or buy? a. b.
