Earnings Per Share [Abstract]  
NET INCOME PER SHARE
NOTE 13—NET INCOME PER SHARE

The Company applies the two-class method to calculate and present net income per share. Certain of the Company's restricted (non-vested) share awards contain non-forfeitable rights to dividends and are considered participating securities for purposes of computing net income per share pursuant to the two-class method. Under the two-class method, net earnings are reduced by the amount of dividends declared (whether paid or unpaid) and the remaining undistributed earnings are then allocated to common stock and participating securities, based on their respective rights to receive dividends.

Basic earnings per common share are calculated by dividing income available to common stockholders by the weighted average number of shares outstanding during each period. Diluted net earnings per common share add to the denominator incremental shares resulting from the assumed exercise of all potentially dilutive stock options, as well as unvested restricted stock and restricted stock units. Options, restricted stock and restricted stock units are primarily held by directors, officers and certain employees.

The Company uses the two-class method to calculate net income per share as both classes share the same rights in dividends. Therefore, basic and diluted earnings per share (“EPS”) are the same for both classes of ordinary shares.
A summary of shares used in the EPS calculations follows (in thousands except share and per share data):
