Earnings Per Share |
Earnings Per Share | 15. Earnings Per Share The Company computes earnings per share using the two-class method, an earnings allocation formula that determines earnings per share for common stock and participating securities according to dividends declared and participation rights in undistributed earnings, when that method results in a more dilutive effect than the Treasury method. The Company's unvested grants of restricted stock contain non-forfeitable rights to dividends, should any be declared, and are treated as participating securities and included in the computation of earnings per share. Net income available to common shareholders and the weighted average number of common shares used to compute basic and diluted earnings per share was as follows:
