1. Your company is considering a new computer system initially costing $1.25 million. It will save $400,000 per year in inventory and receivables management costs. The system is expected to last for five years and will be depreciated using 3-year MACRS. The system is expected to have a salvage value of $25,000 at the end of year 5. There is no impact on net working capital. The marginal tax rate is 21 %. The required return is 9%. Calculate the NPV and IRR for the project.

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?

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.

Each of the following scenarios is independent. All cash flows are after-tax cash flows. Required: 1. Patz Corporation is considering the purchase of a computer-aided manufacturing system. The cash benefits will be 800,000 per year. The system costs 4,000,000 and will last eight years. Compute the NPV assuming a discount rate of 10 percent. Should the company buy the new system? 2. Sterling Wetzel has just invested 270,000 in a restaurant specializing in German food. He expects to receive 43,470 per year for the next eight years. His cost of capital is 5.5 percent. Compute the internal rate of return. Did Sterling make a good decision?
