Earnings Per Share [Abstract] |
Earnings Per Share | NOTE M – EARNINGS PER SHARE ﻿ Basic earnings per share are based on the weighted-average number of shares outstanding for each period. Shares that have been repurchased and retired during the periods specified below have been included in the calculation of the number of weighted-average shares that are outstanding for the calculation of basic earnings per share based on the time they were outstanding in any period. Diluted earnings per common share are based on shares that are outstanding (computed under basic EPS) and on potentially dilutive shares. Shares that are included in the diluted earnings per share calculations under the treasury stock method include equity awards that are in-the-money but have not yet been exercised. ﻿ The following is a reconciliation of the numerator and denominator used to calculate basic earnings per share and diluted earnings per share for the periods indicated: ﻿ ﻿
