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 $3,000,000 and it would be depreciated straight-line to zero over 4 years. Because of radiation contamination, it will actually be completely valueless in 4 years.
