EUAC Analysis
A 5-year-old lathe has been analyzed as a defender and found to have an economic life of 5 years. Its current market value is $5,000, and maintenance cost is $500 per year. Its salvage value at the end of economic life is estimated to be $500.
The challenger is a modern CNC lathe whose analysis indicated its economic life to be 5 years. The CNC lathe is capable of operating as a turning cell due to its automatic tool changer, enhanced integratability, and automatic palletizing. Its first cost is $55,000, while the annual maintenance cost is $400. It is expected to save $14,000 per year through higher productivity. Its estimated salvage value at the end of 5 years is $5,000. Should the defender be replaced, if MARR = 12%?
