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.
