    <footnotes>
        <footnote id="F1">The reported transactions involve an extension of the seven-year exercise period on existing share appreciation rights (SAR) for an additional three-year period. For Form 4 reporting purposes, this is shown as if the outstanding SAR were to be cancelled and replaced by a new SAR. However, from the Issuer's perspective, no new SAR is issued, the Issuer has only extended the expiration term on the original grant, with the same pricing and other terms continuing to apply.</footnote>
        <footnote id="F2">Vesting and exercise of the existing SAR has not changed as a result of the extension and therefore the SAR continues to be immediately exercisable.</footnote>
    </footnotes>

    <remarks>The trading symbols for the Issuer's classes of ordinary shares are LBTYA, LBTYB, and LBTYK.</remarks>
