                    SUPPLEMENT DATED AUGUST 10, 2000 TO THE
            STATEMENT OF ADDITIONAL INFORMATION DATED APRIL 28, 2000
                       SUPERSEDING ALL PRIOR SUPPLEMENTS

     The Statement of Additional Information is hereby supplemented as follows:

     (1) The section entitled "TRUSTEES AND OFFICERS -- OFFICERS" is hereby
amended by deleting all information pertaining to Peter W. Hegel, effective May
31, 2000.

     (2) The last paragraph in the section entitled "DISTRIBUTION AND SERVICE"
is hereby amended by adding Buck Consultants, Inc. to the list of firms that
have entered into agreements with the Distributor to offer shares of the Fund
pursuant to such firm's retirement plan alliance programs.

     (3) The information in the section entitled "OTHER
INFORMATION -- INDEPENDENT ACCOUNTANTS" is hereby deleted in its entirety and
replaced with the following:

     Independent accountants for the Fund perform an annual audit of the Fund's
financial statements. The Fund's Board of Trustees has engaged Ernst & Young
LLP, located at 233 South Wacker Drive, Chicago, Illinois 60606, to be the
Fund's independent accountants, effective May 18, 2000. PricewaterhouseCoopers
LLP, located at 200 East Randolph Drive, Chicago, Illinois 60601 ("PWC"), ceased
being the Fund's independent accountants effective May 18, 2000. The cessation
of the client-auditor relationship between the Fund and PWC was based solely on
a possible future business relationship by PWC with an affiliate of the Fund's
investment adviser. The change in independent accountants was approved by the
Fund's audit committee and the Fund's Board of Trustees, including Trustees who
are not "interested persons" of the Fund (as defined in the 1940 Act).
