Earnings Per Share [Abstract]  
EARNINGS PER SHARE
EARNINGS PER SHARE
 
The Company presents basic and diluted net income per share using the two-class method.   The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders and that determines basic net income per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings that would have been available to common stockholders.   A participating security is defined as a security that may participate in undistributed earnings with common stock.  The Company’s capital structure includes securities that participate with common stock on a one-for-one basis for distribution of dividends.  These are the restricted stock awards authorized within the 2002 and 2013 Equity Participation Plans/Equity Incentive Awards Plan of the Company and restricted stock units authorized within the 2001, 2002 and 2013 Equity Participation Plans/Equity Incentive Awards Plan.  In addition, the Company determines the diluted net income per share by using the more dilutive of the two class-method or the treasury stock method and by including the basic weighted average of outstanding stock options in the calculation of diluted net income per share under the two class-method and including all potential common shares assumed issued in the calculation of diluted net income per share under the treasury stock method.

The following table sets forth the computation of net income per share for the three and six months ended February 28, 2014 and 2013 (in thousands, except per share amounts):
