Consider a project to supply Detroit with 40,000 tons of machine screws annually for automobile production. You will need an initial $5,800,000 investment in threading equipment to get the project started; the project will last for six 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 six-year project life. It also estimates a salvage value of $680,000 after dismantling costs. The marketing department estimates that the automakers will let the contract at a selling price of $300 per ton. The engineering department estimates you will need an initial net working capital investment of $580,000. You require a return of 18 percent and face a marginal tax rate of 30 percent on this project.

a-1 What is the estimated OCF for this project? (Do not round intermediate calculations. Round your answer to the nearest whole number, e.g., 32.) OCF$ ______?

a-2 What is the estimated NPV for this project? (Do not round intermediate calculations. 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 are your worst-case and best-case NPVs for this project? (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places, e.g., 32.16.)

Worst-case $________

Best-case $_________
