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 four 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 four-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.

a-1 What is the estimated OCF for this project?

a-2 What is the estimated NPV for this project?

b. Suppose you believe that the accounting departments initial cost and salvage value projections are accurate only to within 15 percent; the marketing departments price estimate is accurate only to within 10 percent; and the engineering departments 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.)
