The company originally repaired radios and other household appliances when it was founded over 70 years ago. Over the years, the company has expanded, and it is now a reputable manufacturer of various speciality electronic items. Jay McCanless, a recent MBA graduate, has been hired by the company in its 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 items in that is comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffet 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 prototype for a new smartphone that has all the features of the existing one but adds new features such as WiFi tethering. The company has spend a further $200,000 for a marketing study to determine the expected sales figures for the new smartphone. Conch Republic can manufacture the new smart phone for $205 each in variable costs. Fixed costs for the operation are estimated to run $5.1 million per year. The estimated sales volume is 64,000, 106,000, 87,000, 78,000, and 54,000 per year for the next five years respectively. The unit price of the new smart phone will be $485. The necessary equipment can be purchased for $34.5 million and will be depreciated on a seven-year MACRS schedule. It is believed that the value of the equipment in five years will be $5.5 million. 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 years (i.e., there is no initial outlay for NWC). Changes in NWC will thus 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.
