Consider a project to supply Detroit with 20,000 tons of machine screws annually for automobile production. You will need an initial $3,200,000 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 $700,000 and that variable costs should be $200 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 $350,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $310 per ton. The engineering department estimates you will need an initial net working capital investment of $320,000. You require a return of 13 percent and face a marginal tax rate of 38 percent on this project.

a-1. What is the estimated OCF for this project? (Do not round intermediate calculations. Enter your answer in whole dollars, not millions of dollars, e.g., 1,234,567.)

a-2. What is the estimated NPV for this project? (Enter your answer in dollars, not millions of dollars, e.g., 1,234,567. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)

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 the worst-case NPV for this project? The best-case NPV? (A negative answer should be indicated by a minus sign. Enter your answer in dollars, not millions of dollars, e.g., 1,234,567. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.)
