Question 3 (Sensitivity Analysis) Consider a project to supply Detroit with 30,000 tons of machine screws annually for automobile production. You will need an initial $3,800,000 investment in threading equipment to get the project started; the project will last for 4 years. The accounting department estimates that annual fixed costs will be $600,000 and that variable costs should be $340 per ton; accounting will depreciate the initial fixed asset investment straight-line to zero over the 4-year project life. It also estimates a salvage value of $340,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $450 per ton. The engineering department estimates you will need an initial net working capital investment of $380,000. You require a return of 12 percent and face a marginal tax rate of 25 percent on this project. Suppose you're confident about your own projections, but you're a little unsure about Detroit's actual machine screw requirements. a. What is the sensitivity of the project OCF to changes in the quantity supplied? Neil@UPMKB2024 1 b. What about the sensitivity of NPV to changes in quantity supplied? c. Given the sensitivity number you calculated, is there some minimum level of output below which you wouldn't want to operate?
