(6) Earnings Per Share

 

Earnings per share for the three-month and six-month periods ended June 30, 2021 and 2020 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 six-month periods ended June 30, 2021 and 2020: 

               
   Three Months Ended   Six Months Ended
   June 30,   June 30,
   2021   2020   2021   2020
   (In thousands)   (In thousands)

Weighted average number of common shares outstanding during the period used to compute basic earnings per share

   22,842    22,685    22,791   22,612
                    

Incremental common shares attributable to exercise of outstanding options and warrants

   2,288    1,002    2,257   1,171
                    

Weighted average number of common shares used to compute diluted earnings per share

   25,130    23,687    25,048   23,783

 

 

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 six-month periods ended June 30, 2021 would have included an additional 6.0 million and 6.9 million shares, respectively, attributable to the exercise of outstanding options and warrants. For the three-month and six-month periods ended June 30, 2020, an additional 13.3 million and 13.1 million shares, respectively, would be included in the diluted earnings per share calculation.
