Edwards Manufacturing is considering replacing one machine with another

Edwards Manufacturing is considering replacing one machine with another. The old machine was purchased 6 years ago for an installed cost of 130000 USD. The firm is depreciating the machine under MACRS, using a 5-year recovery period (Depreciation percentages are: year 1 = 20%, year 2 = 32%, year 3 = 19%, year 4 = 12%, year 5 = 12%, year 6 = 5%). The new machine costs 159000 USD and requires 5700 USD in installation costs. The firm is subject to a 30% tax rate. When the sale of the old machine, installation cost, and change in NWC are taken into account, the initial investment is 143650 USD. The new machine will operate 9 years. It will generate after-tax incremental cash flow of 31000 USD per year. At the end of the 9th year both book value and market value of the machine are estimated to be 0. Edwards Manufacturing cost of capital is 11%. What is the NPV?
