Earnings per Share

NOTE 6 EARNINGS PER SHARE

 

Basic earnings per share attributable to U.S. Cellular shareholders is computed by dividing Net income attributable to U.S. Cellular shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share attributable to U.S. Cellular shareholders is computed by dividing Net income attributable to U.S. Cellular shareholders by the weighted average number of common shares outstanding during the period adjusted to include the effects of potentially dilutive securities. Potentially dilutive securities primarily include incremental shares issuable upon exercise of outstanding stock options and the vesting of restricted stock units.

 

The amounts used in computing Earnings per Common and Series A Common Share and the effects of potentially dilutive securities on the weighted average number of Common and Series A Common Shares are as follows:

Year ended December 31,2012 2011 2010
(Dollars and shares in thousands, except earnings per share)     
Net income attributable to U.S. Cellular shareholders$ 111,006 $ 175,041 $ 136,074
          
Weighted average number of shares used in basic earnings per share  84,645   84,877   86,128
Effect of dilutive securities:        
 Stock options  58   114   89
 Restricted stock units  364   344   301
         
Weighted average number of shares used in diluted earnings per share  85,067   85,335   86,518
          
Basic earnings per share attributable to U.S. Cellular shareholders$ 1.31 $ 2.06 $ 1.58
          
Diluted earnings per share attributable to U.S. Cellular shareholders$ 1.30 $ 2.05 $ 1.57

Certain Common Shares issuable upon the exercise of stock options or vesting of restricted stock units were not included in average diluted shares outstanding for the calculation of Diluted earnings per share because their effects were antidilutive. The number of such Common Shares excluded is shown in the table below.

(Shares in thousands)     
Stock options 2,452  1,399  1,771
