Carla Co. decides at the beginning of 2017 to adopt the FIFO method of inventory valuation. Carla had used the LIFO method for financial reporting since its inception on January 1, 2015, and had maintained records adequate to apply the FIFO method retrospectively. Carla 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.

		Inventory Determined by				Cost of Goods Sold Determined by
Date		LIFO Method		FIFO Method		LIFO Method		FIFO Method
January 1, 2015		$ 0		$ 0		$ 0		$ 0
December 31, 2015		100		9		790		881
December 31, 2016		200		260		900		749
December 31, 2017		320		390		1,020		1,010

Retained earnings reported under LIFO are as follows.

		Retained Earnings Balance
December 31, 2015		$1,290
December 31, 2016		2,470
December 31, 2017		3,530
