THE FOLLOWING DISCLOSURE REPLACES THE FIRST PARAGRAPH UNDER THE HEADING "SHORT
SALES" FOUND ON PAGE 14 OF THE INVESTOR CLASS PROSPECTUS AND PAGE 15 OF THE
ADVISOR CLASS PROSPECTUS.
A fund may engage in short sales if, at the time of the short sale, the fund
owns or has the right to acquire securities equivalent in kind and amount to the
securities being sold short. Such transactions allow the fund to hedge against
price fluctuations by locking in a sale price for securities it does not wish to
sell immediately.
THE DISCLOSURE SET FORTH IN THE FOLLOWING PARAGRAPHS SHOULD BE INSERTED AFTER
THE SECTION "WHEN-ISSUED SECURITIES" FOUND ON PAGE 14 OF THE INVESTOR PROSPECTUS
AND PAGE 15 OF THE ADVISOR CLASS PROSPECTUS.
INVESTMENTS IN COMPANIES WITH LIMITED OPERATING HISTORY
The funds may invest in the securities of issuers with limited operating
history. The manager considers an issuer to have a limited operating history if
that issuer has a record of less than three years of continuous operation.
Investments in securities of issuers with limited operating history may
involve greater risks than investments in securities of more mature issuers. By
their nature, such issuers present limited operating history and financial
information upon which the manager may base its investment decision on behalf of
the funds. In addition, financial and other information regarding such issuers,
when available, may be incomplete or inaccurate.
The funds will not invest more than 5% of their total assets in the
securities of issuers with less than a three-year operating history. The manager
will consider periods of capital formation, incubation, consolidation, and
research and development in determining whether a particular issuer has a record
of three years of continuous operation.

To reduce expenses and demonstrate respect for our environment, we have
initiated a project through which we will eliminate duplicate copies of most
financial reports and prospectuses to most households and deliver account
statements to most households in a single envelope, even if they have more than
one account. If additional copies of financial reports and prospectuses or
separate mailing of account statements is desired, please call us.
THE FOLLOWING DISCLOSURE IS ADDED ON PAGE 23 OF THE INVESTOR CLASS PROSPECTUS
AND PAGE 19 OF THE ADVISOR CLASS PROSPECTUS, FOLLOWING THE LAST PARAGRAPH UNDER
THE HEADING "WHEN SHARE PRICE IS DETERMINED."
We have contractual relationships with certain financial intermediaries in
which such intermediaries represent that they have systems to track the time at
which investment orders are received and to segregate orders received at
different times. Based on these representations, the fund has authorized such
intermediaries and their designees to accept purchase and redemption orders on
the fund's behalf up to the applicable cut-off time. The fund will be deemed to
have received such orders upon acceptance by the duly authorized intermediary,
and such orders will be priced at the fund's net asset value next determined
after acceptance on the fund's behalf by such intermediary.
