Purple Haze Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $493663 is estimated to result in some amount of annual pretax cost savings. The press will have an aftertax salvage value at the end of the project of $87404. The OCFs of the project during the 4 years are $170641, $190235, $172465 and $164045, respectively. The press also requires an initial investment in spare parts inventory of $27035, along with an additional $2525 in inventory for each succeeding year of the project. The shop's discount rate is 7 percent. What is theNPV for this project?
