QUARTERLY DATA -UNAUDITED [Abstract] |
QUARTERLY DATA -UNAUDITED | 15. QUARTERLY DATA —UNAUDITED We reviewed our RSA agreements and identified that certain RSAs issued contain non-forfeitable rights to dividends prior to their vesting. As a result, those RSAs are considered participating securities which requires us to use the two-class method to compute basic and diluted earnings per shares. Accordingly, we have corrected our reported earnings per share for the corresponding periods. Condensed quarterly financial information is as follows (amounts in thousands, except per share amounts):
