Earnings Per Share

Earnings per share for the three-month periods ended March 31, 2014 and 2013 were calculated using the weighted average number of shares outstanding for the related period. The following table reconciles the number of shares used in the computations of basic and diluted earnings per share for the three-month periods ended March 31, 2014 and 2013:

 

   Three Months Ended 
   March 31, 
   2014   2013 
   (In thousands) 
Weighted average number of common shares outstanding during the period used to compute basic earnings per share   24,355    20,073 
           
Incremental common shares attributable to exercise of outstanding options and warrants   7,656    11,551 
           
Weighted average number of common shares used to compute diluted earnings per share   32,011    31,624 

 

If the anti-dilutive effects of common stock equivalents were considered, shares included in the diluted earnings per share calculation for the three-month periods ended March 31, 2014 and 2013 would have included an additional 2.5 million and 1.3 million shares, respectively, attributable to the exercise of outstanding options and warrants.
