You are evaluating a project for The Farstroke golf club, guaranteed to correct that nasty slice. You estimate the sales price of The Forstroke to be $420 per unit and sales volume to be 1,000 units in year 1,1,500 units in year 2; and 1,325 units in year 3 . The project has a 3-year life. Variable costs amount to $235 per unit and fixed costs are $100,000 per year. The project requires an initial investment of $171,000 in assets, which can be depreciated using bonus depreciation. The actual market value of these assets at the end of year 3 is expected to be $37,000. NWC requirements at the beginning of each year will be approximately 30 percent of the projected sales during the coming yeat, The tax rate is 21 percent and the required return on the project is 12 percent. Whot change in NWC occurs at the end of year 1 ? (Enter a decrease as a negative amount using a minus sign.)
