The two-class method is utilized for the computation of the Company’s EPS. The two-class method requires a portion of net income to be allocated to participating securities, which are unvested awards of share-based payments with non-forfeitable rights to receive dividends that are paid in cash. The Company’s restricted stock awards are participating securities. Income allocated to these participating securities is excluded from net income available to common shares, as shown in the table below. Basic EPS is computed by dividing net income available to basic common shares by the weighted average number of basic common shares outstanding during the period. Diluted EPS is computed by dividing net income available to diluted common shares by the weighted average number of dilutive common shares outstanding during the period.

The following table sets forth the calculation of EPS (in millions, except share and per share data):
