11. Earnings Per Share

The computations of the weighted average shares outstanding for the three and six months ended June 30, 2015 and 2014 are as follows:

 

     Three months ended
June 30,		      Six months ended
June 30,		  

(in millions)

    2015      2014      2015      2014  

Weighted average shares outstanding:

            

Basic

      186.2         184.7         185.8         186.2

      0.2         0.3         0.4         0.9   

Convertible debt

      9.0         2.7         8.4         3.3   
  

 

 

     

 

 

     

 

 

     

 

 

  

Diluted

      195.4         187.7         194.6         190.4   
  

 

 

     

 

 

     

 

 

     

 

 

  

Because it is the Company’s intention to redeem the principal amount of the Senior Subordinated Convertible Notes in cash, the treasury stock method is used for determining potential dilution in the diluted earnings per share computation. As of June 30, 2015, there were 6.0 million restricted share awards with performance-based vesting targets that were not met and as such, have been excluded from the computation of diluted earnings per share.
