Purple Haze Machine Shop is considering a four$-$year project to improve its production efficiency. Buying a new machine press for $$526,528$ is estimated to result in some amount of annual pretax cost savings. The press will have an aftertax salvage value at the end of the project of $$86,879.$ The OCFs of the project during the $4$ years are $$170,654,$ $$199,481,$ $$175,232$ and $$169,873,$ respectively. The press also requires an initial investment in spare parts inventory of $$23,482,$ along with an additional $$1,631$ in inventory for each succeeding year of the project. The shop's discount rate is $6$ percent. What is the NPV for this project?
