(L01) (Accounting Change) Taveras Co. decides at the beginning of 2017 to adopt the FIFO method of inventory valuation. Taveras 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. Taveras 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.
