Your company is considering a machine which will cost $50,000 at Time 0 and which can be sold after 3 years for $10,000. $12,000 must be invested at Time 0 in inventories and receivables; these funds will be recovered when the operation is closed at the end of Year 3. The facility will produce sales revenues of $50,000/year for 3 years; variable operating costs (excluding depreciation) will be 40 percent of sales. No fixed costs will be incurred. Operating cash inflows will begin 1 year from today (at t = 1). By an act of Congress, the machine will have depreciation expenses of $40,000, $5,000, and $5,000 in Years 1, 2, and 3 respectively. The company has a 40 percent tax rate, enough taxable income from other assets to enable it to get a tax refund on this project if the project's income is negative, and a 15 percent required rate of return. Inflation is zero. What is the project's NPV?
