The following is a reconciliation of the basic and diluted earnings per share computation:

 

     Three Months Ended March 31,  
     2015      2014

    $ 12,062       $ 30,204   
  

 

 

     

 

 

  

Shares of common stock and common stock equivalents:

   134,075      130,934   

Dilutive effect of stock options and unvested restricted stock

Weighted averages shares used in dilutive computation

   137,311      138,667   
  

 

 

     

 

 

  

Basic earnings per share

 $ 0.09    $ 0.23   

Dilutive earnings per share

 $ 0.09    $ 0.22   

 

Diluted earnings per share reflects the reduction in earnings per share assuming options or other contracts to issue common stock were exercised or converted into common stock under the treasury stock method. The dilutive effect of options to purchase shares of common stock and restricted shares were included in the diluted earnings per share in the three months ended March 31, 2015, and 2014, respectively. 696 and 545 restricted shares were determined to be anti-dilutive and were not included in the calculation of diluted earnings per share for the three months ended March 31, 2015 and 2014 respectively.
