Earnings Per Share [Abstract]

Schedule Of Earnings Per Share, Basic And Diluted

Shares acquired by the ESOP are not included in basic average shares outstanding until the shares are committed for allocation or vested to an employee's individual account. Unvested shares awarded pursuant to the Company's restricted stock benefit plans are treated as participating securities in the computation of EPS pursuant to the two-class method as they contain nonforfeitable rights to dividends. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security.
