Using the operating cash flow information from the previous problem, determine whether Grady Precision Measurement Tools should add the GPS system to its set of products. The initial investment is $1,440,000 for manufacturing equipment, which will be depreciated over six years (straight line) and will be sold at the end of five years for $380,000. The cost of capital is 10%, and the tax rate is still 35%.

Massey Machine Shop is considering a four-year project to improve its production efficiency. Buying a new machine press for $450,000 is estimated to result in $150,000 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 $90,000. The press also requires an initial investment in spare parts inventory of $18,000, along with an additional $3,000 in inventory for each succeeding year of the project. If the shops tax rate is 35% and its discount rate is 14%, should Massey buy and install the machine press?
