The proposed system is expected to save 12,000 design hours per year, an operating cost savings of $65 per hour. The annual cash expenditures of operating the CAD system are estimated to be $600,000. The CAD system requires an initial investment of $200,000. The estimated life of this system is five years with no salvage value. The tax rate is 21%, and United Technologies uses straight-line depreciation for tax purposes. United Technologies has a cost of capital of 14%.
