Earnings Per Share

Earnings per share for the three-month and nine-month periods ended September 30, 2016 and 2015 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 and nine-month periods ended September 30, 2016 and 2015:

 

   Three Months Ended   Nine Months Ended 
   September 30,   September 30, 
   2016   2015   2016   2015 
   (In thousands)   (In thousands) 
Weighted average number of common shares outstanding during the period used to compute basic earnings per share   23,894    26,093    24,574    25,989 
                     
Incremental common shares attributable to exercise of outstanding options and warrants   4,609    5,383    4,679    5,807 
                     
Weighted average number of common shares used to compute diluted earnings per share   28,503    31,476    29,253    31,796 

 

If the anti-dilutive effects of common stock equivalents were considered, shares included in the diluted earnings per share calculation for the three-month and nine-month periods ended September 30, 2016 would have included an additional 8.6 million and 7.7 million shares, respectively attributable to the exercise of outstanding options and warrants. For the three-month and nine-month periods ended September 30, 2015, an additional 6.7 million and 5.8 million shares, respectively, would be included in the diluted earnings per share calculation.
