Earnings Per Share [Abstract]  
Earnings Per Share Note 16. Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted-average number of shares of common stock outstanding during the period. 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 potentially dilutive shares of common stock been issued. The dilutive effect of stock options, RSUs, performance shares and RSAs are reflected in diluted earnings per share by applying the treasury stock method.

Basic and diluted earnings per share are calculated as follows:
