Revenues 100/year -50/year Operating Expenses Tax rate = 40% In an attempt to improve this projected performance, the firm is considering replacing one of their assets. The replacement is not expected to affect revenues, but the company's operating expenses would be reduced by 10%. The old machine was purchased 3 years ago for $42. At that time it was estimated to have an eight year economic life. Annual straight-line depreciation on the old machine is $5 per year. It could be sold now for $25; and expected to be sold for $2.5 in 5 years (if left in place). The new machine costs $30, has a five year economic life, (straight line depreciation to a 0 book value), and has no expected salvage value.
