The Clemson Manufacturing Corp. engineers have estimated that a new factory can be constructed for the manufacture of hydraulic valves and fittings. Two different technologies, A and B, have been considered in the manufacturing process. The costs of the factory and annual earnings are given below for both technologies. Capital Costs Earnings (in $millions) (in $millions) End of the Year A B A B 0 $10 $15 $0 $0 1 10 10 -1 0 2 10 0 1 2 3 0 0 5 10 4 0 0 10 10 5 0 0 20 10At the end of five years, technology A will have a scrap value of one million dollars, and technology B will have a scrap value of 5 million dollars. Assume that these two projects are equally risky and the appropriate discount rate is 10 percent per year. Calculate the net present value of each of these factories. Determine if either or both would be feasible. Does it matter whether or not real or nominal terms are used for capital costs, cash flows, and discount rate? Explain.
