For purposes of computing EPS, these RSUs are considered to participate with common stock in the earnings of the Corporation and, therefore, the Corporation is required to calculate basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings.
