-Project X involves a new type of graphite composite in-line skate wheel. We think we can sell 6,000 units per year at a price of $1,000 each. Variable costs will run about $400 per unit, and the product should have a four-year life. -Fixed costs for the project will run $450,000 per year. Further, we will need to invest a total of $1,250,000 in manufacturing equipment. This equipment is seven-year MACRS property for tax purposes. In four years, the equipment will be worth about half of what we paid for it. We will have to invest $1,150,000 in net working capital at the start. After that, net working capital requirements will be 25% of sales. -First prepare a pro forma income statement for each year. Next calculate the operating cash flow. Finish the problem by determining total cash flow and then calculating NPV assuming a 28% required return. Use a 21% tax rate throughout.
