Frank Moran manages the cutting department of Greene Timber Company. He purchased a tree-cutting machine on January 1, Year 2, for $200,000. The machine had an estimated useful life of five years and zero salvage value, and the cost to operate it is $45,000 per year. Technological developments resulted in the development of a more advanced machine available for purchase on January 1, Year 3, that would allow a 25 percent reduction in operating costs. The new machine would cost $120,000 and have a four-year useful life and zero salvage value. The current market value of the old machine on January 1, Year 3, 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 $112,000 of revenue per year from the use of either machine.
