Note 11: Earnings Per Common Share

The table below shows earnings per common share and diluted earnings per common share. Basic earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period. Diluted earnings per common share are computed by dividing net income by the average number of common shares outstanding during the period plus the impact of common stock equivalents.

For the three and nine months ended September 30, 2014, options to purchase 1,322 thousand and 1,060 thousand shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.

For the three and nine months ended September 30, 2013, options to purchase 1,356 thousand and 1,979 thousand shares of common stock, respectively, were outstanding but not included in the computation of diluted net income per share because the option exercise price exceeded the fair value of the stock such that their inclusion would have had an anti-dilutive effect.
