Earnings Per Share

6 Months Ended

Jun. 30, 2020

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. The Company’s RSAs are participating securities. Income allocated to these participating securities is excluded from net earnings 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 for the three and six months ended June 30, 2020 and 2019 (in millions, except share data):
