Total fixed costs are $1,470,000 per year, variable production costs are $250 per unit, and the units are priced at $365 each. The equipment needed to begin production has an installed cost of $20,700,000. Because the implants are intended for professional singers, this equipment is considered industrial machinery and thus qualifies as seven-year MACRS property. In five years, this equipment can be sold for about 15 percent of its acquisition cost. AAI is in the 30 percent marginal tax bracket and has a required return on all its projects of 17 percent.
