The Darlington Equipment Company purchased a machine 5 years ago at a cost of $80,000. The machine had an expected life of 10 years at the time of purchase, and it is being depreciated by the straight-line method by $8,000 per year. If the machine is not replaced, it can be sold for $15,000 at the end of its useful life. A new machine can be purchased for $150,000, including installation costs. During its 5-year life, it will reduce cash operating expenses by $40,000 per year. Sales are not expected to change. At the end of its useful life, the machine is estimated to be worthless. MACRS depreciation will be used, and the machine will be depreciated over its 3-year class life rather than its 5-year economic life; so the applicable depreciation rates are 33%, 45%, 15%, and 7%. The old machine can be sold today for $55,000. The firm's tax rate is 40%. The appropriate WACC is 9%. a. If the new machine is purchased, what is the amount of the initial cash flow at Year 0?
