The management of Waterway Instrument Company had concluded, with the concurrence of its independent auditors, that results of operations would be more fairly presented if Waterway changed its method of pricing inventory from last-in, first-out (LIFO) to average-cost in 2020. Given below is the 5-year summary of income under LIFO and a schedule of what the inventories would be if stated on the average-cost method.
