we determine the cost of goods sold by deducting the ending inventory from the cost of goods available for sale, a
highly significant relationship exists: Net income for an accounting period depends directly on the valuation of
ending inventory. This relationship involves three items:
First, a merchandising company must be sure that it has properly valued its ending inventory. If the ending
inventory is overstated, cost of goods sold is understated, resulting in an overstatement of gross margin and net
income. Also, overstatement of ending inventory causes current assets, total assets, and retained earnings to be
overstated. Thus, any change in the calculation of ending inventory is reflected, dollar for dollar (ignoring any
income tax effects), in net income, current assets, total assets, and retained earnings.
Second, when a company misstates its ending inventory in the current year, the company carries forward that
misstatement into the next year. This misstatement occurs because the ending inventory amount of the current year
is the beginning inventory amount for the next year.
Third, an error in one period's ending inventory automatically causes an error in net income in the opposite
direction in the next period. After two years, however, the error washes out, and assets and retained earnings are
properly stated.
Exhibit 44 and Exhibit 45 prove that net income for an accounting period depends directly on the valuation of
the inventory. Allen Company's income statements and the statements of retained earnings for years 2009 and
2010 show this relationship.
