Earnings (Loss) Per Share [Abstract]

Earnings (Loss) Per Share

Earnings Per Share

Basic earnings per common share is computed by dividing net income attributable to Charter shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per common share considers the impact of potentially dilutive securities using the treasury stock and if-converted methods and is based on the weighted average number of shares used for the basic earnings per share calculation, adjusted for the dilutive effect of stock options, restricted stock, restricted stock units, equity awards with market conditions and Charter Holdings convertible preferred units and common units. Charter Holdings common and convertible preferred units were not included in the computation of diluted earnings per share for the three and six months ended June 30, 2017 as their effect was antidilutive. The following is the computation of diluted earnings per common share for the three and six months ended June 30, 2017 and 2016.
