Earnings Per Common Share | Note 13—Earnings Per Common Share Basic and diluted earnings per common share are computed by dividing net income by the weighted-average number of basic and diluted common shares outstanding, respectively. The weighted-average number of diluted common shares includes the impact of dilutive securities, including outstanding stock options, restricted stock units, and performance stock units. The table below reconciles the weighted-average basic and diluted common shares outstanding:
