Consider a project to supply Detroit with 20,000 tons of machine screws annually for automobile production. You will need an initial $3,000,000 investment in threading equipment to get the project started; the project will last for four years. The accounting department estimates that annual fixed costs will be $850,000 and that variable costs should be $450 per ton; accounting will depreciate the initial fixed asset investment straight-line to zero over the four-year project life. It also estimates a salvage value of $280,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $600 per ton. The engineering department estimates you will need an initial net working capital investment of $300,000. You require a 18 percent return and face a marginal tax rate of 38 percent on this project.

a-2. What is the estimated NPV for this project? (Round your answer to 2 decimal places. (e.g., 32.16))

 NPV $   

b. Suppose you believe that the accounting department’s initial cost and salvage value projections are accurate only to within ±15 percent; the marketing department’s price estimate is accurate only to within ±10 percent; and the engineering department’s net working capital estimate is accurate only to within ±5 percent. What is your worst-case and best-case scenario for this project? (Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places. (e.g., 32.16))
