Conflict between short-term versus long-term performance Doyle Construction Components, Inc., purchased a machine on January 1, 2006, for $240,000. The chief engineer estimated the machine’s useful life to be six years and its salvage value to be zero. The operating cost of this machine is $120,000 per year. By January 1, 2008, a new machine that requires 30 percent less operating cost than the existing machine has become available for $180,000; it would have a four-year useful life with zero salvage. The current market value of the old machine on January 1, 2008, is $100,000, and its book value is $160,000 on that date. Straight-line depreciation is used for both machines. The company expects to generate $320,000 of revenue per year from the use of either machine.
