A computerized machining center has been proposed for a small tool manufacturing company. If the new system, which costs $125,000, is installed, it will generate annual revenues of $100,000 and will require $20,000 in annual labor, $12,000 in annual material expenses, and another $8,000 in annual overhead (power and utility) expenses. A loan of $100,000 is borrowed from the bank for installation of the machining center which is repaid by equal annual repayments in 5 years at an interest rate of 8% compounded quarterly. Note that there is a working-capital requirement of $23,331 in year 0 and full recovery of the working capital at the end of year 5 for the machining center.

The machining center would be classified as a seven-year MACRS property. If the asset is held for eight years, we can depreciate a seven-year property in respective percentages of 14.29%, 24.49%, 17.49%, 12.49%, 8.93%, 8.92%, 8.93%, and 4.46%. The company expects to phase out the facility at the end of five years, at which time it will be sold for $50,000. Find the year-by-year after-tax net cash flow for the project at a 40% marginal tax rate based on the net income and determine the after tax net present worth of the project at the companys MARR of 15%.
