Earnings Per Share |
14. | Earnings Per Share
Diluted earnings per share includes common shares assumed issued under the “treasury stock method,” which reflects the potential dilution that would occur if any outstanding options are exercised. Diluted earnings per share also includes the “if converted” method for participating securities if the result is dilutive. The two-class method of calculating diluted earnings per share is used whether the “if converted” result is dilutive or anti-dilutive. The calculation of basic and diluted EPS for the years ended December 31, 2012, 2011 and 2010 are presented below.
