The computation of basic earnings per share is based on the weighted average number of common shares outstanding. The computation of diluted earnings per share is based on the weighted average number of shares of common stock outstanding plus the shares resulting from the assumed exercise or vesting of all outstanding share-based awards using the treasury stock method. Weighted-average antidilutive stock options to purchase 2.9 million, 2.8 million and 2.2 million shares of Company common stock with a weighted average exercise price of $20.64, $21.75 and $23.46 per share for 2012, 2011 and 2010, respectively, were excluded from diluted shares. Antidilutive other equity awards covering approximately 36,000 shares of Company common stock for 2011 were also excluded from diluted shares. There were no antidilutive other equity awards for 2012 and 2010. The following tables provide a reconciliation of the numerators and denominators of the basic and diluted earnings per share computations for the years ended December 31, 2012, 2011 and 2010:
