The Campbell Company is considering adding a robotic paint sprayer to its production line. The sprayer's base price is $990,000, and it would cost another $21,500 to install it. The machine falls into the MACRS 3-year class (the applicable MACRS depreciation rates are 33.33%,44.45%,14.81%, and 7.41% ), and it would be sold after 3 years for $647,000. The machine would require an increase in net working capital (inventory) of $19,000. The sprayer would not change revenues, but it is expected to save the firm $484,000 per year in before-tax operating costs, mainly labor. Campinal tax a. What is the Year-0 net cash flow? $ b.
