CHAPTER CASE Conch Republic Electronics onch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The com- pany president is Shelly Couts, who inherited the com- pany. The company originally repaired radios and other household appliances when it was founded more than 70 years ago. Over the years, the company has expanded, and it is now a reputable manufacturer of various specialty 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 manu- factured by Conch Republic is a smartphone. Conch Republic currently has one smartphone model on the market and sales have been excellent. The smartphone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett mu- sic. However, as with any electronic item, technology changes rapidly, and the current smartphone has limited features in comparison with newer models. Conch Re- public spent $750,000 to develop a 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 spent 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, re- spectively. The unit price of the new smartphone 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 the value of the equip ment in five years will be $5.5 million Net working capital for the smartphones will be 20 percent of sales and will occur with the timing of the cash flows for the year (t.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 Shelly has asked Jay to prepare a report that an- swers the following questions: QUESTIONS 1. What is the payback period of the project? 2. What is the profitabilty index of the project? 3. What is the IRR of the project? 4. What is the NPV of the project? 5. How sensitive is the NPV to changes in the price of the new smartphone? 6. How sensitive is the NPV to changes in the quan- tity sold? 7. Should Conch Republic produce the new smartphone? 8. Suppose Conch Republic loses sales on other models because of the Introduction of the new model. How would this affect your analysis
