Computation of Earnings per Common Share
Note 2. Computation of Earnings per Common Share
Basic earnings per common share (“EPS”) is computed by dividing the net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is computed using the same method as basic EPS, however, the computation reflects the potential dilution that would occur if all dilutive securities were exercised and converted into common stock.
Unvested stock-based compensation awards containing
non-forfeitable
rights to dividends paid on the Company’s common stock are considered participating securities, and therefore are included in the
two-class
method for calculating EPS. Under the
two-class
method, all earnings (distributed and undistributed) are allocated to common shares and participating securities based on their respective rights to receive dividends on the common stock. The Company grants restricted stock to certain employees under its stock-based compensation plan. Recipients receive cash dividends during the vesting periods of these awards, including on the unvested portion of such awards. Since these dividends are
non-forfeitable,
the unvested awards are considered participating securities and therefore have earnings allocated to them.
