Purple Haze Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $542,563 is estimated to result in $189,863 in annual pretax cost savings. The press falls in the MACRS five-year class, and it will have a salvage value at the end of the project of $103,326. The shop's tax rate is 30 percent. What is the OCF for year 4?
