Earnings Per Share [Abstract]  
Earnings Per Share Earnings Per Share
We compute basic earnings per share by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per common and potential common share includes the weighted average of additional shares associated with the incremental effect of dilutive restricted stock and restricted stock units, as prescribed by the Financial Accounting Standards Board (FASB) guidance on earnings per share.
The following table reconciles basic and diluted weighted average shares used in the computation of earnings per share (in thousands, except per share data):
