[1] ^{The Company issues restricted shares of Class A common stock and restricted Class B units that have non-forfeitable dividend rights.  Under the "two-class method," these shares and units are considered participating securities and are required to be included in the computation of basic and diluted earnings per share.}

[2] ^{During the nine months ended September 30, 2020, the calculation of diluted earnings per share resulted in an increase in earnings per share. Therefore, diluted earnings per share is assumed to be equal to basic earnings per share. Please refer to Note 5, “Earnings per Share,” for further details.}
