Earnings Per Share [Abstract]

Earnings Per Share

8. EARNINGS PER SHARE

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity. For CCA diluted earnings per share is computed by dividing net income by the weighted average number of common shares after considering the additional dilution related to restricted stock-based compensation and stock options.

A reconciliation of the numerator and denominator of the basic earnings per share computation to the numerator and denominator of the diluted earnings per share computation is as follows (in thousands, except per share data):

Approximately 1.5 million and 1.3 million stock options were excluded from the computations of diluted earnings per share for the three months ended March 31, 2012 and 2011, respectively, because they were anti-dilutive.
