Exercise 20-1
Requirement 1
January 1, 2018 ($ in millions)
Retained earnings……………………………………………………………….. 30
Inventory (cumulative effect) * ………………………………………….. 30
2017 2016 Total
Since the cost of goods available for sale each period is the sum of the cost of goods sold
and the cost of goods unsold (inventory), a $30 million difference ($16 + 14) in cost of
goods sold due to using FIFO rather than Average means there also is a $30 million
difference in inventory. The cumulative prior year difference in cost of goods sold is
reflected as a difference in prior years’ income and, therefore, the balance in retained
earnings.
