Mannisto, Inc., uses the FIFO inventory cost flow assumption. In a year of rising costs and prices, the firm reported net income of $244,087 and average assets of $1,550,550. If Mannisto had used the LIFO cost flow assumption in the same year, its cost of goods sold would have been $44,110 more than under FIFO, and its average assets would have been $40,630 less than under FIFO. Required: Calculate the firm's ROA under each cost flow assumption. Suppose that two years later costs and prices were falling. Under FIFO, net income and average assets were $288,567 and $1,880,970, respectively. If LIFO had been used through the years, inventory values would have been $45,690 less than under FIFO, and current year cost of goods sold would have been $22,660 less than under FIFO.
