Earnings per Share [Abstract]

Earnings per Share

(13)    Earnings Per Share

Basic earnings per share is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock; however, potential common equivalent shares are excluded if their effect is anti-dilutive.

The following table sets forth the reconciliation of basic and diluted net income per share for the three and six months ended June 30, 2013 and 2012 (in thousands, except per share data):

Diluted	$	0.75	$	0.77	$	1.45	$	1.50

The calculation of diluted earnings per share for the three and six months ended June 30, 2013 excluded from the denominator 271,300 shares of common stock options, and the calculation of diluted earnings per share for the three and six months ended June 30, 2012 excluded from the denominator 371,000 shares of common stock options, because their effect would have been anti-dilutive.
