We are evaluating a project that costs $1,860,000, has a 6 -year life, and has no salvage value. Assume that depreciation is straight-line to zero over the life of the project. Sales are projected at 89,300 units per year. Price per unit is $38.31, variable cost per unit is $23.50, and fixed costs are $833,000 per year. The tax rate is 21 percent, and we require a return of 9 percent on this project. a. Calculate the base-case operating cash flow and NPV. Note: Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16. b. What is the sensitivity of NPV to changes in the sales figure? Note: Do not round intermediate calculations and round your answer to 3 decimal places, e.g., 32.161. c. If there is a 450-unit decrease in projected sales, how much would the NPV change? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16. d. What is the sensitivity of OCF to changes in the variable cost figure? Note: A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32 . e. If there is a $1 decrease in estimated variable costs, how much would the OCF change? Note: Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32
