Nash Co. decides at the beginning of 2020 to adopt the FIFO method of inventory valuation. Nash had used the LIFO method for financial reporting since its inception on January 1, 2018, and had maintained records adequate to apply the FIFO method retrospectively. Nash concluded that FIFO is the preferable inventory method because it reflects the current cost of inventory on the balance sheet. The following table presents the effects of the change in accounting principles on inventory and cost of goods sold. Income taxes are ignored. | | Inventory Determined by | | Cost of Goods Sold Determined by | Date | | LIFO Method | | FIFO Method | | LIFO Method | | FIFO Method | January 1, 2018 | | $ 0 | | $ 0 | | $ 0 | | $ 0 | December 31, 2018 | | 100 | | 8 | | 880 | | 972 | December 31, 2019 | | 180 | | 210 | | 900 | | 778 | December 31, 2020 | | 290 | | 360 | | 1,030 | | 990 | Retained earnings reported under LIFO are as follows. | | Retained Earnings Balance | December 31, 2018 | | $850 | | December 31, 2019 | | 1,680 | | December 31, 2020 | | 2,380 | | 1. | | For each year presented, sales are $2,780 and operating expenses are $1,050. | 2. | | Nash provides two years of financial statements.
