Earnings Per Share [Abstract]

Net Earnings Per Common Share

Note 11.Net Earnings Per Common Share

Basic net earnings per common share is computed using the weighted average common shares outstanding during the period. Diluted net earnings per common share is computed by using the weighted average common shares outstanding including the dilutive effect of stock options, shares issued under the Employee Stock Purchase Plan and restricted shares based on an average share price during the period. For the nine month periods ended September 30, 2014 and 2013, approximately 0.0 and 0.1 shares of the Company’s common stock, respectively, were excluded from the determination of diluted earnings per common share because their effect would have been anti-dilutive (none for the three months ended September 30, 2014 and 2013). The computations of basic and diluted earnings per share for the three and nine months ended September 30, 2014 and 2013, respectively, are as follows:
