Earnings Per Share

For the quarters and nine months ended September 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 September 30,		Nine Months Ended September 30,
In thousands	2018	2017	2018	2017
Basic average common shares outstanding	17,216	17,055	17,189	17,028
Effect of dilutive options and restricted stock awards	133	212	150	242
Diluted average common shares outstanding	17,349	17,267	17,339	17,270

For each of the quarters ended September 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 nine months ended September 30, 2018 and 2017, stock options for 150,005 shares and 38,280 shares of Common Stock were not considered in computing diluted earnings per common share because they were antidilutive.
