        <footnote id="F1">On October 5, 2018, a grantor retained annuity trust (&quot;GRAT&quot;) of which the reporting person is trustee transferred 14,365 Class A Common Shares to the remainder beneficiaries of the GRAT in satisfaction of the GRAT's obligations upon its termination.</footnote>
        <footnote id="F2">17,646 of these Class A Common Shares were previously reported as indirectly beneficially owned through a GRAT of which the reporting person is trustee, but on October 5, 2018 such shares were delivered to the reporting person in satisfaction of the GRAT's annuity obligations.  As a result, such shares are again directly owned by the reporting person.</footnote>

    <remarks>The reporting person may be 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 August 22, 2018.</remarks>
