E22-3B (Accounting Change) Kyto Electronics decides to adopt the average cost method of inventory valuation at the beginning of 2014. Kyto had used the LIFO method for financial reporting since its inception on January 1, 2012, and had maintained records adequate to apply the average-cost method retrospectively. Kyto concluded that average-cost is the preferable inventory method because extreme effects of FIFO or LIFO on the income statement and balance sheet are averaged. The following table presents the effects of the change in accounting principles on inventory and cost of goods sold for each year.
