    <remarks>The reporting person may have been deemed to have shared voting power with respect to more than 10% of the Class A Common Shares of the Issuer (due solely to the convertibility of Common Voting Shares of the Company into Class A Common Shares on a share-for-share basis) due to the voting provisions of the Amended and Restated Scripps Family Agreement dated May 19, 2015, as amended on March 29, 2017, to which the reporting person is a party. The reporting person filed a Schedule 13D with the Commission on January 24, 2013, as last amended on January 11, 2019.  The reporting person no longer holds any Common Voting Shares and therefore is no longer subject to this agreement.</remarks>
