Earnings Per Share [Abstract] |
Per Common Share Information | Per Common Share Information Diluted earnings per common share is calculated using net income divided by diluted weighted-average shares. Diluted weighted-average shares include weighted-average shares outstanding plus the dilutive effect of share-based compensation, calculated using the treasury stock method, of 6.9 million shares and 7.1 million shares for the quarters 2019 and 2018, respectively, and 6.9 million shares and 7.6 million shares for the six months 2019 and 2018, respectively. Share-based compensation awards that would have been antidilutive, and therefore were not included in the calculation of diluted weighted-average shares, totaled 1.1 million shares and 2.6 million shares for the quarters 2019 and 2018, respectively, and 2.0 million shares and 2.6 million shares for the six months 2019 and 2018, respectively.
