    <remarks>The board of directors of the issuer has determined that the reporting person no longer meets the definition of &quot;officer&quot; under Rule 16a-1(f) of the Securities Exchange Act of 1934. As a result, the reporting person is no longer subject to Section 16 in connection with his transactions in the equity securities of the issuer and therefore will no longer report any such transactions on Form 4 or Form 5.</remarks>
