Earnings per common share: |
Earnings per Common Share | Note 2. Earnings per Common Share Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) No. 260-10-45 addresses whether instruments granted in share-based payment transactions are participating securities prior to vesting and, therefore, need to be included in the earnings allocation in computing earnings per share (“EPS”). The restricted stock awards granted by the Company contain non-forfeitable rights to dividends and therefore are considered participating securities. The two-class method for calculating basic EPS excludes dividends paid to participating securities and any undistributed earnings attributable to participating securities. Earnings per common share have been computed based on the following:
