Note 6. Earnings per Common Share

Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding for the period.

Diluted earnings per common share takes into account the potential dilution that could occur if outstanding securities were exercised. Dilutive securities are included in the calculation of diluted earnings per common share using the treasury stock method in accordance with ASC Topic 260, “Earnings per Share.” Dilutive securities include outstanding stock options, restricted stock units and performance share units granted to employees and non-employee directors (see Note 14).

Weighted-average common shares outstanding—diluted is the same as weighted-average common shares outstanding—basic in periods when a net loss is reported or in periods when anti-dilution occurs.

The following table summarizes the computation of basic and diluted earnings per share (in thousands, except per share data):
