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. Diluted earnings per common share will also reflect the dilutive effect of potential common shares from the conversion of the Convertible Notes. Convertible debt in which the principal amount must be settled in cash is excluded from the calculation of diluted earnings per share. There would be no interest expense adjustment to the numerator for the cash-settled portion of the Convertible Notes because that portion will always be settled in cash. The conversion spread value in shares will be included in diluted earnings per share using the if-converted method if the convertible debt is in the money. The denominator of diluted earnings per share is determined by dividing the conversion spread value of the share-settled portion of the Convertible Notes as of the reporting date by the average share price over the reporting period. For the three and nine months ended September 30, 2023, the convertible debt was not in the money; therefore, no incremental shares were assumed converted or included in the diluted earnings per share calculation below. For further details about the Convertible Notes, see Note 11. The following table reconciles numerators and denominators of CenterPoint Energy’s basic and diluted earnings per common share.
