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 5.9 million shares and 6.7 million shares for the quarters 2020 and 2019, respectively. Share-based compensation awards that would have been antidilutive, and therefore were not included in the calculation of diluted weighted-average shares, totaled 2.0 million shares for each of the quarters 2020 and 2019.
