Aria Acoustics, Incorporated (AAI), projects unit sales for a new seven-octave voice emulation implant as follows:

Year	Unit Sales
1	71,000
2	84,000
3	103,000
4	95,000
5	64,000

Production of the implants will require $2.3 million in net working capital to start and additional net working capital investments each year equal to 15 percent of the projected sales increase for the following year. Total fixed costs are $2.9 million per year, variable production costs are $285 per unit, and the units are priced at $410 each. The equipment needed to begin production has an installed cost of $14.8 million. Because the implants are intended for professional singers, this equipment is considered industrial machinery and thus qualifies as seven-year MACRS property (MACRS schedule). In five years, this equipment can be sold for about 20 percent of its acquisition cost. The tax rate is 21 percent tax and the required return is 18 percent.
