The following information supplements disclosure under "The Fund's Main
Investment Strategy" section of the fund's prospectuses:

Securities Lending. The fund may lend its investment securities in an amount up
to 33 1/3% of its total assets to approved institutional borrowers who need to
borrow securities in order to complete certain transactions.

The following information supplements disclosure under "The Main Risks of
Investing in the Fund" section of the fund's prospectuses:

Securities Lending Risk. Any loss in the market price of securities loaned by
the fund that occurs during the term of the loan would be borne by the fund and
would adversely affect the fund's performance. Also, there may be delays in
recovery of securities loaned or even a loss of rights in the collateral should
the borrower of the securities fail financially while the loan is outstanding.
However, loans will be made only to borrowers selected by the fund's delegate
after a review of relevant facts and circumstances, including the
creditworthiness of the borrower.

Supplement to the currently effective  Statements of Additional  Information for
the listed Fund:

DWS Core Fixed Income Fund
--------------------------------------------------------------------------------

The  following   information  replaces  similar  information  contained  in  the
"Investment  Policies  and  Techniques"  section  of the  Fund's  Statements  of
Additional Information.


Lending  Portfolio  Securities.  Each  Fund may  lend  portfolio  securities  to
brokers,  dealers and other  financial  organizations.  These loans, if and when
made by a Fund,  may not exceed 33 1/3% of the value of the Fund's total assets.
A Fund's loans of securities will be collateralized by cash, cash equivalents or
US Government  securities.  The cash or instruments  collateralizing  the Fund's
loans of securities will be maintained at all times in a segregated account with
the Fund's custodian, in an amount at least equal to the current market value of
the loaned securities.  From time to time, a Fund may pay a part of the interest
earned from the investment of collateral  received for securities  loaned to the
borrower and/or a third party that is  unaffiliated  with the Fund and is acting
as a "placing broker." No fee will be paid to affiliated persons of the Fund.

By lending portfolio securities, a Fund can increase its income by continuing to
receive  amounts equal to the interest or dividends on the loaned  securities as
well as by either  investing the cash  collateral in short-term  instruments  or
obtaining  yield in the form of interest paid by the borrower when US Government
securities  are used as  collateral.  A Fund  will  comply  with  the  following
conditions whenever it loans securities: (i) the Fund must receive at least 100%
cash collateral or equivalent  securities  from the borrower;  (ii) the borrower
must increase the collateral  whenever the market value of the securities loaned
rises  above  the  level  of the  collateral;  (iii)  the  Fund  must be able to
terminate the loan at any time; (iv) the Fund must receive  reasonable  interest
on the  loan,  as well as  amounts  equal to the  dividends,  interest  or other
distributions  on the loaned  securities,  and any increase in market value; (v)
the Fund may pay only reasonable custodian fees in connection with the loan; and
(vi) voting  rights on the loaned  securities  may pass to the  borrower  except
that,  if a material  event will occur  affecting  the  investment in the loaned
securities,  the Fund must  terminate the loan in time to vote the securities on
such event.
