5. Massey Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $640,000 is estimated to result in $270,000 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 $70,000. The press also requires an initial investment in spare parts inventory of $20,000, along with an additional $3,500 in inventory for each succeeding year of the project. If the shops tax rate is 35 percent and its discount rate is 14 percent, should Massey buy and install the machine press? (Assume that dNWC will be fully recovered in the last year of the project.)
