Cold Duck Manufacturing Inc. is a company that produces iWidgets, among several other products. Suppose that Cold Duck Manufacturing Inc. considers replacing its okJ machine used to make iWidgets with a more efficient one, which would cost S 1, 800 and require $250 annually in operating costs except depreciation. After-tax salvage value of the old machine is $600, while its annual operating costs except depreciation are $1, 100. Assume that, regardless of the age of the equipment, Cold Duck Manufacturing Inc.'s sales revenues are fixed at $3, 500 and depreciation on the old machine is $600. 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 Cold Duck Manufacturing Inc.'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. Complete the following table and calculate incremental cash flows in each year. Next evaluate the incremental flows by calculating the net present value (NPV), the internal rate of return (IRR), and the modified IRR (MIRR). Assume again that the cost of financing the new project is the same as the WACC and equate 10%
