1A. 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 $4,800,000, 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 $1,430,000 per year for four years. Assume that the tax rate is 21 percent. You can borrow at 8 percent before taxes. Calculate the net advantage to leasing (NAL). B. Refer to information in question 1. If the tax rate is 40 what is the net advantage to leasing?
