       disclosure in the filings;

    (b)Staff comments or changes to disclosure in response to Staff comments in
       the filings reviewed by the Staff do not foreclose the Commission from
       taking any action with respect to the filings; and

       proceeding initiated by the Commission or any person under the federal
       securities laws of the United States.

                                             Sincerely,
