EARNINGS PER SHARE

15. Earnings Per Share

 

Basic earnings per share is the amount of earnings (adjusted for dividends declared on preferred stock) available to each share of common stock outstanding during the reporting period. Diluted earnings per share is the amount of earnings available to each share of common stock outstanding during the reporting period adjusted to include the effect of potentially dilutive common shares. Potentially dilutive common shares include incremental shares issued for stock options, restricted stock units and awards, distributions from deferred compensation plans, and the conversion of the Company's convertible preferred stock (See Note 14). Potentially dilutive common shares are excluded from the computation of diluted earnings per share in periods in which the effect would be antidilutive. For diluted earnings per share, net income available to common shares can be affected by the conversion of the Company's convertible preferred stock. Where the effect of this conversion would be dilutive, net income available to common shareholders is adjusted by the associated preferred dividends and deemed dividend. The calculation of basic and diluted earnings per share for each of the three years ended December 31 was as follows:

      Year ended December 31,
(dollar amounts in thousands, except per share amounts)   2012     2011     2010
                   
Basic earnings per common share:                
Net income $ 641,022   $ 542,613   $ 312,347
Preferred stock dividends, deemed dividends and accretion of discount   (31,989)     (30,813)     (172,032)
  Net income available to common shareholders $ 609,033   $ 511,800   $ 140,315
Average common shares issued and outstanding   857,962     863,691     726,934
Basic earnings per common share $ 0.71   $ 0.59   $ 0.19
                   
Diluted earnings per common share                
Net income available to common shareholders $ 609,033   $ 511,800   $ 140,315
Effect of assumed preferred stock conversion   ---     ---     ---
  Net income applicable to diluted earnings per share $ 609,033   $ 511,800   $ 140,315
Average common shares issued and outstanding   857,962     863,691     726,934
Dilutive potential common shares:                
  Stock options and restricted stock units and awards   4,202     2,916     1,722
  Shares held in deferred compensation plans   1,238     1,017     876
  Conversion of preferred stock   ---     ---     ---
Dilutive potential common shares:   5,440     3,933     2,598
  Total diluted average common shares issued and outstanding   863,402     867,624     729,532
Diluted earnings per common share $ 0.71   $ 0.59   $ 0.19

Approximately 24.4 million, 23.6 million, and 18.5 million options to purchase shares of common stock outstanding at the end of 2012, 2011, and 2010, respectively, were not included in the computation of diluted earnings per share because the effect would be antidilutive.
