        <footnote id="F1">Shares of unrestricted Class A Common Stock were acquired upon the vesting of a prior grant of Performance-based Restricted Stock Units (&quot;PRSUs&quot;) awarded with respect to compensation for 2013, including certain Restricted Stock Units (&quot;RSUs&quot;) that had been acquired pursuant to the dividend equivalent reinvestment provisions of the underlying PRSU award.  The grant was previously reflected in the Company's proxy statements.  The PRSUs and RSUs that had been acquired pursuant to the award had previously been converted into shares of Restricted Class A Common Stock in connection with the reporting person's retirement eligibility and such shares remained subject to vesting.</footnote>
        <footnote id="F2">Amount excludes 1,880 RSUs beneficially owned by the reporting person.</footnote>
