There were no employee stock-based compensation awards that would have had an antidilutive effect on the computation of diluted earnings per share for the three and nine months ended September 30, 2013 or September 30, 2012. | Earnings Per Share Basic earnings per share are computed using the weighted average number of common shares outstanding during the period. Diluted earnings per share incorporate the incremental shares issuable upon the assumed exercise of stock options and the assumed vesting of RSUs and restricted stock. Certain of our stock options and restricted stock were excluded from the calculation of diluted earnings per share because they were antidilutive, but these equity instruments could be dilutive in the future. The following chart sets forth the computation of earnings per share (in thousands, except per share amounts):
| Year Ended December 31,
| 2012 |  | 2011 |  | 2010
Income from continuing operations | $ | 261,225 |  |  | $ | 210,264 |  |  | $ | 167,118 |

Diluted earnings per share from continuing operations | $ | 0.87 |  |  | $ | 0.71 |  |  | $ | 0.57 |
The following table sets forth the number of employee stock-based compensation awards outstanding but not included in the computation of diluted earnings per share because their effect would have been antidilutive (in thousands):
