Earnings Per Share [Abstract] |
Earnings Per Share (CenterPoint Energy) | Earnings Per Share (CenterPoint Energy) Basic earnings per common share is computed by dividing income available to common shareholders by the basic weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding, including all potentially dilutive common shares, if the effect of such common shares is dilutive. Diluted earnings per common share reflects the dilutive effect of potential common shares from share-based awards. The dilutive effect of restricted stock is computed using the treasury stock method, as applicable, which includes the incremental shares that would be hypothetically vested in excess of the number of shares assumed to be hypothetically repurchased with the assumed proceeds. The following table reconciles numerators and denominators of CenterPoint Energy’s basic and diluted earnings per common share.
