A company is considering a 6-year project that requires an initial outlay of $21,000. The project engineer has estimated that the operating cash flows will be $4,000 in year 1, $6,000 in year 2, $7,000 in year 3, $7,000 in year 4, $7,000 in year 5, and $7,000 in year 6. At the end of the project, the equipment will be fully depreciated, classified as 5-year property under MACRS. The project engineer believes the equipment can be sold for $6,000 at the end of the project. If the tax rate is 37% and the required rate of return is 12%, what is the net present value (NPV) of this project?
