Purple Haze Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $524724 is estimated to result in $228930 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 $102817. The shop's tax rate is 34 percent. What is the OCF for year 4?
