(11-6) New-Project Analysis The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $920,000, and it would cost another $20,000 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $500,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $15,500. The sprayer would not change revenues, but it is expected to save the firm $304,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 25% a. What is the Year-0 cash flow? Answer -$955,500. b. What are the cash flows in Years 1, 2, and 3? Answer + $306,326, $332,458, $262,804. c. What is the additional Year-3 cash flow (i.e., the after-tax salvage and the return of working capital)? Answer 407,913.50. d. If the project's cost of capital is 12%, what is the NPV? Answer + NPV = $60,441.11
