Earnings Per Share [Abstract] |
EARNINGS PER SHARE | 11. EARNINGS PER SHARE Diluted earnings per share were computed based on the weighted average number of shares outstanding plus all potentially dilutive common shares. A reconciliation of basic to diluted shares used in the earnings per share calculation is as follows:
|  | (In thousands, except stock options outstanding) |
|  | Three Months Ended |  | Six Months Ended |
|  | June 30, |  | June 30, |
|  | 2012 |  | 2011 |  | 2012 |  | 2011 |
Basic weighted average shares outstanding |  | 46,820 |  | 46,311 |  | 46,737 |  | 46,250 |
Dilutive effect of stock options and deferred stock compensation |  | 681 |  | 704 |  | 782 |  | 741 |
Diluted weighted average shares outstanding |  | 47,501 |  | 47,015 |  | 47,519 |  | 46,991 |
As of June 30, 2012 and 2011, there were 638,000 and 660,000 stock options outstanding, respectively, that could potentially dilute earnings per share in the future, which were excluded from the computation of diluted earnings per share as they would be considered anti-dilutive.
