Earnings Per Share
12. Earnings Per Share
Basic earnings per share represents net income for the period common shares were outstanding, divided by the weighted average number of common shares outstanding for the period. Diluted earnings per share represents net income divided by the weighted average number of common shares outstanding, inclusive of the effect of dilutive securities such as outstanding stock options, SARs, stock units and warrants.
The following are the common share amounts used to compute the basic and diluted earnings per share for each period:
                                 
    For the Three Months     For the Six Months  
    Ended June 30,     Ended June 30,  
    2011     2010     2011     2010  
    (in thousands)  
Weighted average shares used in basic computations
    119,007       119,054       118,609       119,686  
Dilutive effect of exercise of equity grants outstanding
    7,350       6,221       7,748       6,128  
Dilutive effect of warrants
    260       410       253       398  
 
                       
Weighted average shares used in diluted computations
    126,617       125,685       126,610       126,212  
 
                       
There were an aggregate of 1.2 million of equity grants that were outstanding during both the three and six months ended June 30, 2011, and an aggregate of 4.1 million and 4.4 million of equity grants that were outstanding during the three and six months ended June 30, 2010, respectively, consisting of stock options, SARs, and stock units, but were not included in the computation of diluted earnings per share because their effect would be anti-dilutive.
