A firm is analyzing a 4-year project. The project requires an initial investment of $695,000 in equipment. In addition, the firm must increase net operating working capital (NOWC) by $70,000 at Year 0, which will be fully recovered at the end of the project (Year 4). The project will generate annual operating cash flow (OCF) of $358,000 for Years 1 through 4. At the end of Year 4, the equipment is expected to be sold for an after-tax salvage value (ATSV) of $110,000. The company’s discount rate is 12 percent. Calculate the NPV of this project

A financial analyst is evaluating an investment that generates uneven cash flows over time. The project is expected to produce a cash inflow of $12,000 at the end of Year 2, a cash inflow of $15,000 at the end of Year 3, and a final cash inflow of $18,000 at the end of Year 5. All cash flows are assumed to be reinvested at an annual rate of 9%. Using this information, determine the future value of all cash flows at the end of Year 10. Round to the nearest dollar.
