entitled "MORTGAGE BACK SECURITIES" on page 2 of the Statement of
Additional Information:
"The Fund may invest in mortgage-backed securities primarily by investing in
another mutual fund that owns securities and that is advised by an affiliate

in such securities directly."
2. Please insert the following as the last subsection to the section
entitled "DERIVATIVE CONTRACTS" which begins on page 4 of the Statement
of Additional Information:
"SWAPS. Swaps are contracts in which two parties agree to pay each other
(swap) the returns derived from underlying assets with differing
characteristics. Most swaps do not involve the delivery of the underlying
assets by either party, and the parties might not own the assets underlying
the swap. The payments are usually made on a net basis so that, on any given
day, the Fund would receive (or pay) only the amount by which its payment
under the contract is less than (or exceeds) the amount of the other party's
payment. Swap agreements are sophisticated instruments that can take many
different forms, and are known by a variety of names including caps, floors,
and collars. Common swap agreements that the Fund may use include:
INTEREST RATE SWAPS. Interest rate swaps are contracts in which one
party agrees to make regular payments equal to a fixed or floating
interest rate times a stated principal amount of fixed income
securities, in return for payments equal to a different fixed or
floating rate times the same principal amount, for a specific period.
For example, a $10 million LIBOR swap would require one party to pay the
equivalent of the London Interbank Offer Rate of interest (which
fluctuates) on $10 million principal amount in exchange for the right to
receive the equivalent of a stated fixed rate of interest on $10 million
principal amount.
CAPS AND FLOORS. Caps and Floors are contracts in which one party agrees
to make payments only if an interest rate or index goes above (Cap) or
below (Floor) a certain level in return for a fee from the other party.
TOTAL RETURN SWAPS. Total return swaps are contracts in which one party
agrees to make payments of the total return from the underlying asset
during the specified period, in return for payments equal to a fixed or
floating rate of interest or the total return from another underlying
asset."

entitled "SPECIAL TRANSACTIONS" on page 5 of the Statement of
Additional Information:
"SECURITIES OF OTHER INVESTMENT COMPANIES
The Fund may invest its assets in securities of other investment
companies, including the securities of money market funds, as an
efficient means of carrying out its investment policies. It should be
noted that investment companies incur certain expenses, such as
management fees, and therefore, any investment by the Fund in shares of
other investment companies may be subject to such duplicate expenses."
