The Advisor has contractually agreed effective June 1, 2016 through May 31,

to maintain the fund's total annual operating expenses (excluding certain
expenses such as extraordinary expenses, taxes, brokerage and interest expense)

Effective June 1, 2016, the following disclosure under the "POLICIES ABOUT
TRANSACTIONS" heading of the "INVESTING IN THE FUNDS" section of the fund's
prospectus is applicable to the fund.


CLASS A TO INSTITUTIONAL CLASS IN THE SAME FUND EXCHANGE PRIVILEGE. Investors
who have invested in Class A shares through a comprehensive or "wrap" fee
program or other fee-based program sponsored by a broker-dealer, bank or
registered investment adviser, or who are transferring to such a program may
potentially become eligible to invest in Institutional Class shares by reason
of their participation in such a program. In such event, subject to the
discretion of the Distributor and the limitations noted below, such
shareholders may exchange their Class A shares for Institutional Class shares
of equal aggregate value of the same fund. No sales charges or other charges
will apply to any such exchange. Exchanges under this privilege will be
processed only as part of a pre-arranged, multiple-client transaction through
the particular financial services firm offering the comprehensive or wrap
program or other fee-based program where the Institutional Class shares are
available. Investors should contact their selling and/or servicing agents to
learn more about the details of this exchange feature. Shareholders generally
will not recognize a gain or loss for federal income tax purposes upon the
exchange of Class A shares of a fund for Institutional Class shares of the same
fund.


CLASS S TO INSTITUTIONAL CLASS IN THE SAME FUND EXCHANGE PRIVILEGE. Investors
who have invested in Class S shares through a comprehensive or "wrap" fee
program or other fee-based program sponsored by a broker-dealer, bank or
registered investment adviser may potentially become eligible to invest in
Institutional Class shares by reason of their participation in such a program.
In such event, subject to the discretion of the Distributor and the limitations
noted below, such shareholders may exchange their Class S shares for
Institutional Class shares of equal aggregate value of the same fund. No sales
charges or other charges will apply to any such exchange. Exchanges under this
privilege will be processed only as part of a pre-arranged, multiple-client
transaction through the particular financial services firm offering the
comprehensive or wrap program or other fee-based program where the
Institutional Class shares are available. Investors should contact their
selling and/or servicing agents to learn more about the details of this
exchange feature. Shareholders generally will not recognize a gain or loss for
federal income tax purposes upon the exchange of Class S shares of a fund for
Institutional Class shares of the same fund.


CLASS A, CLASS R, CLASS S OR INSTITUTIONAL CLASS TO CLASS R6 IN THE SAME FUND
EXCHANGE PRIVILEGE. Investors who have invested in Class A, Class R, Class S or
Institutional Class shares through a retirement plan platform with plan-level
or omnibus accounts held on the books of the fund may potentially become
eligible to invest in Class R6 shares by reason of their participation in such
a plan. Exchanges under this privilege are subject to the discretion of the
Distributor and will be processed only as part of a prearranged, plan-level
transaction with a qualifying retirement plan program. If an exchange by a
qualifying retirement plan program is approved, investors holding Class A,
Class R, Class S or Institutional Class shares through such retirement plan
will exchange those shares for Class R6 shares of equal aggregate value of the
same fund. No sales charges or other charges will apply to any such exchange.
Investors should contact their retirement plan servicing agents to learn more
about the details of this exchange feature. Shareholders generally will not
recognize a gain or loss for federal income tax purposes upon the exchange of
Class A, Class R, Class S or Institutional Class shares of a fund for Class R6
shares of the same fund.
