10. Replacement analysis Aa Aa Purple Turtie Group is a company that produces iBooks, among several other products. Suppose that Purple Turtle Group considers replacing its old machine used to make iBooks with a more efficient one, which would cost $1,700 and require $380 annually in operating costs except depreciation. After-tax salvage value of the old machine is $700, while its annual operating costs except depreciation are $1,000. Assume that, regardless of the age of the equipment, Purple Turtle Group's sales revenues are fixed at $4,500 and depreciation on the old machine is $700. 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%. , and they are constant over four Based on the data, net cash flows (NCFs) before replacement are years Although Purple Turtle Group's NCFs before replacement are the same over the 4-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.
