Note 6 – Earnings per Share
 
The computation of earnings per share, as presented in the Consolidated Statements of Income, is based on the weighted average number of shares outstanding during each period.  There were 14,128,146 weighted average shares outstanding during the second quarter of 2013, and 14,103,209 during the second quarter of 2012.  There were 14,120,865 weighted average shares outstanding during the first six months of 2013, and 14,102,544 during the first six months of 2012.
 
Diluted earnings per share include the effect of the potential issuance of common shares, which for the Company is limited to shares that would be issued on the exercise of "in-the-money" stock options.  The dilutive effect of options outstanding was calculated using the treasury stock method, excluding anti-dilutive shares and adjusting for unamortized expense and windfall tax benefits.  For the second quarter and first six months of 2013 the dilutive effect of options outstanding calculated under the treasury stock method totaled 99,189 and 91,045, respectively, which were added to basic weighted average shares outstanding for purposes of calculating diluted earnings per share.  Likewise, for the second quarter and first six months of 2012 shares totaling 4,431 and 4,872, respectively, were added to basic weighted average shares outstanding in order to calculate diluted earnings per share.
