        <footnote id="F1">Represents the substitution of shares previously included in a Grantor Retained Annuity Trust (&quot;GRAT&quot;) established by the Reporting Person for estate planning purposes, under which he is the sole trustee and sole annuitant.  As such, the Reporting Person's total beneficial ownership in FCX has not changed, as he was the beneficial owner of these shares both before and after the transfer, and the amount reported as beneficially owned through his GRATs has been reduced accordingly.</footnote>
        <footnote id="F2">Amounts reported as beneficially owned reflect 350,000 shares transferred from the Reporting Person's direct ownership to a GRAT in a transaction exempt under Rule 16a-13.</footnote>
        <footnote id="F3">Amount beneficially owned following the reported transactions includes 1,128,000 Common Stock Restricted Stock Units, 1,000,000 of which are vested but deferred.</footnote>
