Ramirez Co. decides at the beginning of 2019 to adopt the FIFO method of inventory valuation. Ramirez had used the average-cost method for financial reporting since its inception on January 1, 2017, and had maintained records adequate to apply the FIFO method retrospectively. Ramirez concluded that FIFO is the preferable inventory method because it reflects the current cost of inventory on the statement of financial position. The following table presents the effects of the change in accounting policy on inventory and cost of goods sold.

Retained earnings reported under average-cost are as follows.

Retained Earnings Balance

December 31, 2017..............................$2,200

December 31, 2018................................4,200

December 31, 2019................................6,070

Other information:

1. For each year presented, sales are $4,000 and operating expenses are $1,000.
