Earnings Per Share [Abstract]  
Earnings Per Share EARNINGS PER SHARE
Basic earnings per share is calculated by dividing net income, adjusted for income allocated to participating securities, 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. DTE Energy's participating securities are restricted shares under the stock incentive program that contain rights to receive non-forfeitable dividends. Performance shares do not receive cash dividends; as such, these awards are not considered participating securities. For additional information regarding performance shares, see Note 20 to the Consolidated Financial Statements, "Stock-Based Compensation."
The following is a reconciliation of DTE Energy's basic and diluted income per share calculation for the years ended December 31:
