Basic earnings per share is computed based on the weighted-average number of common shares outstanding during the period. Diluted earnings per share is computed based on the weighted-average number of common shares outstanding adjusted by the number of additional shares, if any, that would have been outstanding had the potentially dilutive common shares been issued. Potentially dilutive shares of common stock include non-qualified stock options and restricted stock units. The computation of weighted average dilutive shares outstanding excluded non-qualified stock options to purchase 0.5 million and 1.4 million shares of common stock during the three months ended September 30, 2012 and 2011, respectively, and 0.5 million and 1.2 million shares of common stock during the nine months ended September 30, 2012 and 2011, respectively. These options were excluded because the options’ exercise prices were greater than the average market price of the Company’s common stock for the periods presented and, therefore, the effect would be anti-dilutive.
