2 129,500

3 117,500

4 100,500

Production of the implants will require $1,750,000 in net working capital to start and additional net working capital investments each year equal to 20 percent of the projected sales increase for the following year. Total fixed costs are $1,400,000 per year, variable production costs are $230 per unit, and the units are priced at $350 each. The equipment needed to begin production has an installed cost of $25,500,000. Because the implants are intended for professional singers, this equipment is considered industrial machinery and thus qualifies as seven-year MACRS (MACRS Table) property. In five years, this equipment can be sold for about 10 percent of its acquisition cost. AAI is in the 34 percent marginal tax bracket and has a required return on all its projects of 17 percent.
