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, 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 three and nine months ended September 30, 2018 and 2017, where income represents the numerator and weighted average shares represent the denominator.

The calculation of diluted earnings per share excluded stock awards and convertible debentures which would be anti-dilutive. The calculation of diluted earnings per share excluded 2 million and 6 million stock awards outstanding for the three and nine months ended September 30, 2018 and 2017, respectively, that could potentially dilute basic earnings per share in the future.
