Earnings Per Share

For the quarters and six months ended June 30, 2018 and 2017, basic earnings per share were computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Unexercised stock options and unvested restricted shares are excluded from this calculation but are included in the diluted earnings per share calculation using the treasury stock method as long as their effect is not antidilutive.

The following table provides a reconciliation of weighted-average shares used to determine basic and diluted earnings per share:



	Quarter Ended June 30,		Six Months Ended June 30,
In thousands	2018	2017	2018	2017
Basic average common shares outstanding	17,196	17,044	17,178	17,014
Effect of dilutive options and restricted stock awards	139	218	156	258
Diluted average common shares outstanding	17,335	17,262	17,334	17,272

For each of the quarters ended June 30, 2018 and 2017, stock options for 162,830 shares and 38,280 shares of Common Stock were not considered in computing diluted earnings per common share because they were antidilutive.

For each of the six months ended June 30, 2018 and 2017, stock options for 149,940 shares and 38,280 shares of Common Stock were not considered in computing diluted earnings per common share because they were antidilutive.
