16. Due to a clerical error, the Form 4 filed on June 12, 2019 inadvertently reflected in Column 5 of Table II that, in connection with the conversion of shares of Class B Common Stock to Class A Common Stock, shares of Class B Common Stock were acquired rather than disposed of. This amendment is being filed to correct Column 5 of Table II. All other information set forth in the June 12, 2019 Form 4 remains correct and is restated in its entirety.
