Earnings Per Common Share

14. Earnings Per Common Share

Basic earnings per common share is computed by dividing net income attributable to Holdings’ common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is computed by dividing net income attributable to Holdings’ common stockholders by the weighted average number of common shares outstanding during the period and the effect of all dilutive common stock equivalents. In periods where there is a net loss, diluted loss per common share is equal to basic loss per common share, since the effect of including any common stock equivalents would be antidilutive.

For the years ended December 31, 2019, 2018 and 2017, the computation of diluted earnings per common share included the effect of 0.6 million, 1.3 million and 1.7 million dilutive stock options and restricted stock units, respectively. For the years ended December 31, 2019, 2018 and 2017, the computation of diluted earnings per common share excluded the effect of 3.5 million, 0.7 million and 0.4 million antidilutive stock options and restricted stock units, respectively. Earnings per common share for the years ended December 31, 2019, 2018 and 2017 was calculated as follows:
