The management of Iroquois National Bank is considering an investment in automatic teller machines. The machines would cost $170,200 and have a useful life of seven years. The bank’s controller has estimated that the automatic teller machines will save the bank $37,000 after taxes during each year of their life (including the depreciation tax shield). The machines will have no salvage value.
