Basic earnings per share is based on the average number of shares of common stock outstanding during each period. Diluted earnings per share is based on the average number of shares of common stock used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options and restricted stock units using the “treasury stock” method.
