8. Replacement analysis Aa Aa Purple Whale Inc. is a company that produces iGadgets, among several other products. Suppose that Purple Whale Inc. considers replacing its old machine used to make iGadgets with a more efficient one, which would cost $2,000 and require $280 annually in operating costs except depreciation. After-tax salvage value of the old machine is $400, while its annual operating costs except depreciation are $1,200. Assume that, regardless of the age of the equipment, Purple Whale Inc.'s sales revenues are fixed at $2,500 and depreciation on the old machine is $400 Assume also that the tax rate is 40% and the project's risk-adjusted cost of capital, r, is the same as weighted average cost of capital (WACC) and equals 10% Based on the data, net cash flows (NCFs) before replacement are and they are constant over four years Although Purple Whale Inc.'s NCFs before replacement are the same over the four-year period, its NCFs after replacement vary annually. The following table shows depreciation rates over four years Year 1 Year 2 Year 3 Year 4 Depreciation rates 33.33% 44.45% 14.81% 7.41% Complete the following table and calculate incremental cash flows in each year. Hint: Round your answers to the nearest dollar and remember to enter a minus sign if the calculated value is negative.
