Basic earnings per share is computed using the weighted-average number of outstanding shares of common stock during the period. Diluted earnings per share is computed using the weighted-average number of outstanding shares of common stock and, when dilutive, potential shares of common stock outstanding during the period (“common stock equivalents”). Common stock equivalents consist of incremental shares issuable upon the assumed exercise of stock options and vesting of restricted stock units utilizing the treasury stock method.
