You are considering a new product launch. The project will cost $1,450,000, have a four-year life, and have no salvage value; depreciation is straight-line to zero. Sales are projected at 160 units per year; price per unit will be $17,000, variable cost per unit will be $10,000, and fixed costs will be $440,000 per year. The required return on the project is 12 percent, and the relevant tax rate is 21 percent. a-1. The unit sales, variable cost, and fixed cost projections given above are probably accurate to within 10 percent. What are the upper and lower bounds for these projections? What is the basecase NPV? What are the best-case and worst-case scenarios? (Do not round intermediate calculations and round your answers to the nearest whole number, e.g., 32.) a-2. What is the base-case NPV? What are the best-case and worstcase scenarios? (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.) b. Calculate the sensitivity of your base-case NPV to changes in fixed costs. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161.) c. What is the accounting break-even level of output for this project? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
