Earnings Per Share [Abstract]  
Basic and Diluted Net Income (Loss) Per Share
Basic Income Per Common Share and Diluted Income Per Common Share
Basic income per common share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted income per common share gives effect to all potentially dilutive common shares that were outstanding during the period. As of December 31, 2012, 2011 and 2010 we had outstanding stock options and RSUs that could potentially dilute basic earnings per share in the future.
The following represents a reconciliation of the numerator and denominator used in computing basic and diluted income available to common stockholders per common share for the years ended December 31, 2012, 2011 and 2010:
