Earnings Per Share [Abstract] |
EARNINGS PER SHARE | EARNINGS PER SHARE Basic and diluted earnings per share are based on the weighted-average number of shares of common stock and potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted earnings per share, includes the effects of dilutive restricted stock units, stock options and convertible securities. The effect of such potential common stock is computed using the treasury stock method or the if-converted method, as applicable. The following table is a reconciliation of the numerator and denominator of the basic and diluted earnings per share computation for income from continuing operations for the years ended December 31, 2017, 2016 and 2015, where income represents the numerator and weighted-average shares represent the denominator. Values are in millions except per share data:

_____________________________
(1) | Loss from continuing operations, net of tax, of $20 million less the $5 million adjustment to retained earnings to record the DP&L redeemable preferred stock at its redemption value as of December 31, 2016.
The calculation of diluted earnings per share excluded 7 million, 8 million and 8 million stock awards outstanding for the years ended December 31, 2017, 2016 and 2015, respectively, that could potentially dilute basic earnings per share in the future. Additionally, for the years ended December 31, 2016 and 2015, all 15 million convertible debentures were omitted from the earnings per share calculation. The Company redeemed all of its existing TECONs in June 2017. The stock awards and convertible debentures were excluded from the calculation because they were anti-dilutive.
