Earnings Per Share
2.   Earnings Per Share

The Company accounts for the shares acquired by its ESOP and the shares awarded pursuant to its RRP in accordance with Accounting Standards Codification ("ASC") 260, which requires that unvested RRP awards that contain nonforfeitable rights to dividends be treated as participating securities in the computation of earnings per share pursuant to the two-class method. The two-class method is an earnings allocation that determines earnings per share for each class of common stock and participating security. Shares acquired by the ESOP are not considered in the basic average shares outstanding until the shares are committed for allocation or vested to an employee's individual account.
