A project will produce an operating cash flow of $7,300 a year for three years. The initial investment for fixed assets will be $11,600, which will be depreciated straight-line to zero over the assets 4-year life. The project will require an initial $500 in net working capital plus an additional $500 every year with all net working capital levels restored to their original levels when the project ends. The fixed assets can be sold for an estimated $2,500 at the end of the project, the tax rate is 34 percent, and the required rate of return is 12 percent. What is the net present value of the project?

Please explain the rhetoric behind the cash flows for each year, by line, not just the excel sheet. Thank you
