Suppose we are thinking about replacing an old computer with a new one. The old one cost us $1.4 million; the new one will cost $1.7 million. The new machine will be depreciated straight-line to zero over its five-year life. It will probably be worth about $325,000 after five years. The old computer is being depreciated at a rate of $281,000 per year. It will be completely written off in three years. If we don't replace it now, we will have to replace it in two years. We can sell it now for $450,000; in two years, it will probably be worth $130,000. The new machine will save us $315,000 per year in operating costs. The tax rate is 22 percent, and the discount rate is 12 percent. a-1. Calculate the EAC for the old and the new computer. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) a-2. What is the NPV of the decision to replace the computer now?

New computer EAC a-2. NPV

Although the Chen Company’s milling machine is old, it is still in relatively good working order and would last for another 10 years. It is inefficient compared to modern standards, though, and so the company is considering replacing it. The new milling machine, at a cost of $110,000 delivered and installed, would also last for 10 years and would produce after-tax cash flows (labor savings and depreciation tax savings) of $19,000 per year. It would have zero salvage value at the end of its life. The project cost of capital is 10%, and its marginal tax rate is 25%. Should Chen buy the new machine?

Gina Ripley, president of Dearing Company, is considering the purchase of a computer-aided manufacturing system. The annual net cash benefits and savings associated with the system are described as follows: The system will cost 9,000,000 and last 10 years. The companys cost of capital is 12 percent. Required: 1. Calculate the payback period for the system. Assume that the company has a policy of only accepting projects with a payback of five years or less. Would the system be acquired? 2. Calculate the NPV and IRR for the project. Should the system be purchasedeven if it does not meet the payback criterion? 3. The project manager reviewed the projected cash flows and pointed out that two items had been missed. First, the system would have a salvage value, net of any tax effects, of 1,000,000 at the end of 10 years. Second, the increased quality and delivery performance would allow the company to increase its market share by 20 percent. This would produce an additional annual net benefit of 300,000. Recalculate the payback period, NPV, and IRR given this new information. (For the IRR computation, initially ignore salvage value.) Does the decision change? Suppose that the salvage value is only half what is projected. Does this make a difference in the outcome? Does salvage value have any real bearing on the companys decision?

Friedman Company is considering installing a new IT system. The cost of the new system is estimated to be 2,250,000, but it would produce after-tax savings of 450,000 per year in labor costs. The estimated life of the new system is 10 years, with no salvage value expected. Intrigued by the possibility of saving 450,000 per year and having a more reliable information system, the president of Friedman has asked for an analysis of the projects economic viability. All capital projects are required to earn at least the firms cost of capital, which is 12 percent. Required: 1. Calculate the projects internal rate of return. Should the company acquire the new IT system? 2. Suppose that savings are less than claimed. Calculate the minimum annual cash savings that must be realized for the project to earn a rate equal to the firms cost of capital. Comment on the safety margin that exists, if any. 3. Suppose that the life of the IT system is overestimated by two years. Repeat Requirements 1 and 2 under this assumption. Comment on the usefulness of this information.
