Earnings Per Share [Abstract]  
Earnings Per Share


Note 18. Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of shares of common stock that would have been outstanding had potential dilutive shares of common stock been issued. The dilutive effect of stock options, RSUs and performance share units are reflected in diluted earnings per share by applying the treasury stock method.

A reconciliation of the amounts included in the computation of basic earnings per share from continuing operations and diluted earnings per share from continuing operations is as follows:
