Conch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The company president is Shelley Couts, who inherited the company. When it was founded over 70 years ago, the company originally repaired radios and other household appliances. Over the years, the company expanded into manufacturing and is now a reputable manufacturer of various electronic items. Jay McCanless, a recent NYU-SPS graduate, has been hired by the company's finance department.

One of the major revenue-producing items manufactured by Conch Republic is a smart phone. Conch Republic currently has one smart phone model on the market, and sales have been excellent. The smart phone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett music

However, as with any electronic item, technology changes rapidly, and the current smart phone has limited features in comparison with newer models. Conch Republic spent $750,000 to develop a prototype for a new smart phone that has all the features of the existing smart phone but adds new features such as WiFi tethering. The company has spent a further $200,000 for a marketing study to determine the expected sales figures for the new smart phone.

Conch Republic can manufacture the new smart phones for $215 each in variable costs. Fixed costs for the operation are estimated to run $6.1 million per year. The estimated sales volume is 155,000, 165,000, 125,000, 95,000, and 75,000 per year for the next five years, respectively. The unit price of the new smart phone will be $520.

The necessary equipment can be purchased for $40.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the equipment in five years will be $6.1 million. SALVAGE

Net working capital for the smart phones will be 20 percent of sales and will occur with the timing of the cash flows for the year; for example, there is no initial outlay for NWC, but changes in NWC will first occur in Year 1 with the first year's sales.

Conch Republic has a 35 percent corporate tax rate and a required return of 12 percent.
