21-34 Equipment replacement, no income taxes. Dublin Chips is a manufacturer of prototype chips based inDublin, Ireland. Next year, in 2018, Dublin Chips expects to deliver 615 prototype chips at an average price of$95,000. Dublin Chips' marketing vice president forecasts growth of 65 prototype chips per year through 2024.That is, demand will be 615 in 2018, 680 in 2019, 745 in 2020, and so on.The plant cannot produce more than 585 prototype chips annually. To meet future demand, Dublin Chipsmust either modernize the plant or replace it. The old equipment is fully depreciated and can be sold for$4.200,000 if the plant is replaced. If the plant is modernized, the costs to modernize it are to be capitalized anddepreciated over the useful life of the updated plant. The old equipment is retained as part of the modernizealternative. The following data on the two options are available:ModernizeReplaceInitial investment in 2018$35,300,000$66,300,000Terminal disposal value in 2024$ 7,500,000$16,000,000Useful life7 years7 yearsTotal annual cash operating costs per prototype chip$78,500$66,000Dublin Chips uses straight-line depreciation, assuming zero terminal disposal value.
