[1] Participating share awards with right to receive dividend equivalents are under the two class method excluded from the earnings per share calculation (see Note 14).

[2] The Company’s unvested RSUs and PSs, which include the right to receive non-forfeitable dividend equivalents, are considered participating securities. Calculations of EPS under the two-class method exclude from the numerator any dividends paid or owed on participating securities and any undistributed earnings considered to be attributable to participating securities. The related participating securities are similarly excluded from the denominator.
