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 RSUs and stock options. The effect of such potential common stock is computed using the treasury stock method. 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, 2019, 2018 and 2017, where income represents the numerator and weighted-average shares represent the denominator.
Year Ended December 31, | 2019 |  | 2018 |  | 2017
(in millions, except per share data) | Income |  | Shares |  | $ per Share |  | Income |  | Shares |  | $ per Share |  | Loss |  | Shares |  | $ per Share
BASIC EARNINGS (LOSS) PER SHARE |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Income (loss) from continuing operations attributable to The AES Corporation common stockholders | $ | 302 |  |  | 664 |  |  | $ | 0.46 |  |  | $ | 985 |  |  | 662 |  |  | $ | 1.49 |  |  | $ | (507 | ) |  | 660 |  |  | $ | (0.77 | )
EFFECT OF DILUTIVE SECURITIES |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Restricted stock units | — |  |  | 3 |  |  | (0.01 | ) |  | — |  |  | 3 |  |  | (0.01 | ) |  | — |  |  | — |  |  | — |
DILUTED EARNINGS (LOSS) PER SHARE | $ | 302 |  |  | 667 |  |  | $ | 0.45 |  |  | $ | 985 |  |  | 665 |  |  | $ | 1.48 |  |  | $ | (507 | ) |  | 660 |  |  | $ | (0.77 | )
The calculation of diluted earnings per share excluded stock awards which would be anti-dilutive. The calculation of diluted earnings per share excluded 2 million and 7 million stock awards outstanding for the years ended December 31, 2018 and 2017, respectively, that could potentially dilute basic earnings per share in the future. For the year ended December 31, 2017, the calculation of diluted earnings per share also excluded 4 million outstanding restricted stock units that could potentially dilute earnings per share in the future, because their impact would be anti-dilutive given the loss from continuing operations. Had the Company generated income, 2 million potential shares of common stock related to the restricted stock units would have been included in diluted weighted-average shares outstanding.
