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. Diluted earnings per share for the six months ended June 30, 2013 excludes the impact of approximately 0.6 million common stock equivalents 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):
