| Earnings per share | 9. Earnings per share: We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common share includes the weighted average of additional shares associated with the incremental effect of dilutive employee stock options and non-vested restricted stock, as determined using the treasury stock method prescribed by the Financial Accounting Standards Board (“FASB”) guidance on earnings per share. The following table reconciles basic and diluted weighted average shares used in the computation of earnings per share for the quarters and nine months ended September 30, 2011 and 2010:
We excluded the impact of anti-dilutive potential common shares from the calculation of diluted weighted average shares for the quarter and nine months ended September 30, 2011 and 2010. If these potential common shares were included in the calculation, the impact would have been a decrease in diluted weighted average shares outstanding of 34,563 shares and 47,870 shares for the quarters ended September 30, 2011 and 2010, respectively, and 35,156 shares and 257,781 shares for the nine months ended September 30, 2011 and 2010, respectively. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
