Earnings Per Share [Abstract] |
Earnings Per Share | 12. Earnings Per Share The following is a reconciliation of the basic and diluted earnings per share computation:
|  | Year Ended December 31, |
|  | 2016 |  |  | 2015 |  |  | 2014 |
Net income |  | $ | 26,155 |  |  | $ | 80,052 |  |  | $ | 61,051 |
|  | (shares in thousands) |
Shares of common stock and common stock equivalents: |  |  |  |  |  |  |  |  |  |  |  |
Weighted average common shares used in basic computation |  |  | 134,401 |  |  |  | 137,242 |  |  |  | 131,770 |
Dilutive effect of common stock equivalents |  |  | 1,138 |  |  |  | 1,583 |  |  |  | 6,781 |
Weighted average common shares used in dilutive computation |  |  | 135,539 |  |  |  | 138,825 |  |  |  | 138,551 |
Basic earnings per share |  | $ | 0.19 |  |  | $ | 0.58 |  |  | $ | 0.46 |
Diluted earnings per share |  | $ | 0.19 |  |  | $ | 0.58 |  |  | $ | 0.44 |
In the table above, unvested share-based awards that have non-forfeitable rights to dividends or dividend equivalents are treated as a separate class of securities in calculating EPS. Diluted earnings per share reflects the reduction in earnings per share assuming options or other contracts to issue common stock were exercised or converted into common stock (if dilutive) under the treasury stock method. The Company excluded 996,000 and 1,247,000 common stock equivalents from its computation of diluted earnings per share for the years ended December 31, 2016 and 2014, respectively, as they were determined to be anti-dilutive. There were no anti-dilutive common stock equivalents included in the calculation of diluted earnings per share for the year ended December 31, 2015.
