Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share is computed by dividing net income available to common stockholders by the weighted-average number of common shares plus the effect of dilutive potential common shares outstanding during the period. The diluted earnings per share for the years ended December 31, 2013, 2012 and 2011 exclude the impact of approximately 0.3 million, 1.8 million and 2.2 million common stock equivalents, respectively, since the effect of including these securities would be anti-dilutive. The following table sets forth the computation of basic and diluted earnings per share (shares in thousands):
