Earnings Per Share [Abstract] |
EARNINGS PER SHARE AND DIVIDENDS | EARNINGS PER SHARE AND DIVIDENDS Basic earnings per share is calculated by dividing net income attributable to DT Midstream by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect the dilution that would occur if any potentially dilutive instruments were exercised or converted into common shares, using the treasury stock method. Restricted stock units and performance share awards, including dividend equivalents on those grants, are potentially dilutive and, if dilutive, are included in the determination of weighted-average shares outstanding. Restricted stock units and performance share awards do not receive cash dividends, as such, these awards are not considered participating securities. The following is a reconciliation of basic and diluted earnings per share:
