Earnings Per Share [Abstract]
Earnings Per Share	Note 3 - Earnings Per Share Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares outstanding during the periods presented. In computing diluted earnings per common share for the three months and nine months ended September 30, 2018, and 2017, the Company assumes that all dilutive outstanding options to purchase common shares have been exercised at the beginning of the period (or the time of issuance, if later). The dilutive effect of these outstanding options and the restricted shares is reflected by application of the treasury stock method, whereby the proceeds from exercised options and restricted shares are assumed to be used to purchase common shares at the average market price during the respective periods. The weighted average common shares outstanding used in computing basic earnings per common share for the three months ended September 30, 2018 and 2017 were 67,635,058 and 66,140,518 shares, respectively. The weighted average common shares outstanding used in computing basic earnings per common share for the nine months ended September 30, 2018 and 2017 were 67,586,843 and 66,104,914 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the three months ended September 30, 2018 and 2017 were 68,053,724 and 66,417,281 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the nine months ended September 30, 2018 and 2017 were 67,948,420 and 66,392,210 shares, respectively. For the three and nine months ended September 30, 2018 and 2017, there were no weighted average outstanding stock options that were anti-dilutive that have been excluded from the earnings per share calculation.

Note 3 - Earnings Per Share

Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted average number of shares outstanding during the periods presented. In computing diluted earnings per common share for the three months and nine months ended September 30, 2018, and 2017, the Company assumes that all dilutive outstanding options to purchase common shares have been exercised at the beginning of the period (or the time of issuance, if later). The dilutive effect of these outstanding options and the restricted shares is reflected by application of the treasury stock method, whereby the proceeds from exercised options and restricted shares are assumed to be used to purchase common shares at the average market price during the respective periods. The weighted average common shares outstanding used in computing basic earnings per common share for the three months ended September 30, 2018 and 2017 were 67,635,058 and 66,140,518 shares, respectively. The weighted average common shares outstanding used in computing basic earnings per common share for the nine months ended September 30, 2018 and 2017 were 67,586,843 and 66,104,914 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the three months ended September 30, 2018 and 2017 were 68,053,724 and 66,417,281 shares, respectively. The weighted average common shares outstanding used in computing fully diluted earnings per common share for the nine months ended September 30, 2018 and 2017 were 67,948,420 and 66,392,210 shares, respectively. For the three and nine months ended September 30, 2018 and 2017, there were no weighted average outstanding stock options that were anti-dilutive that have been excluded from the earnings per share calculation.
