The UFRO Company is considering the replacement of an existing spectrometer with a new spectrometer; faster and with expanded capacity. If the new spectrometer is purchased, the existing (old) computer will be sold for $80,000 immediately. The existing spectrometer was purchased three (3) years ago for $500,000. It is being depreciated under the 3-year MACRS schedule. The salvage value at the end of its six-year life will be $50,000. The new spectrometer will be purchased for $800,000. If the new spectrometer is purchased, accounts receivable increase immediately by $25,000; accruals will increase immediately by $40,000; and accounts payable will increase immediately by $30,000. The UFRO Company has a 30% corporate tax rate. Shipping and installation will cost UFRO $80,000; and the modifications to the building will be $100,000.
