Q6: You work for a nuclear research laboratory that is contemplating leasing a diagnostic scanner (leasing is 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 $1430,000 per year for four years (pay at the end of the year). Assume that the tax rate is 21 percent. You can borrow at 8 percent before taxes. What's the net present value of leasing? Should you lease or buy? (15")
