SUPPLEMENT TO THE CURRENTLY EFFECTIVE PROSPECTUSES:

                                 -----------------

                       DWS Dreman Concentrated Value Fund

Upon the recommendation of Deutsche Investment Management Americas Inc. (the
"Advisor"), the Board of the above-listed fund approved the termination and
liquidation of the fund effective on or about June 5, 2009 (the "Liquidation
Date"). Accordingly, the fund will redeem all of its shares outstanding on the
Liquidation Date. The costs of each liquidation, including the mailing of
notification to shareholders, will be borne by the fund subject to the Advisor's
agreement to maintain the fund's total operating expenses at specified levels.
Shareholders may exchange their shares for the same class of another DWS fund or
redeem their shares prior to the Liquidation Date. Shareholders who elect to
exchange into another DWS fund may do so at net asset value minus any applicable
redemption fee, and without payment of any contingent deferred sales charge
("CDSC"). Shareholders who elect to redeem their shares prior to the Liquidation
Date will receive the net asset value per share for all shares they redeem minus
any applicable redemption fees and CDSC on such redemption date. Shareholders
whose shares are redeemed by the fund on the Liquidation Date will receive the
net asset value per share for all shares they own on the Liquidation Date
without the deduction of any redemption fees or CDSC. The exchange or redemption
of shares, on or before the Liquidation Date, may be a taxable event for
shareholders with the exception of those participating in individual retirement
accounts, qualified defined contribution and defined benefit plans or other
qualified retirement vehicles.

In conjunction with approving the termination and liquidation of the
above-listed fund, the Board of the fund further approved closing the fund to
new investments effective immediately, except that qualified retirement plans
that currently offer the fund as an investment option may continue to offer it
to their participants until the Liquidation Date.

The following information replaces similar disclosure in the "Other Policies and
Secondary Risks" section of the fund's prospectuses:

As a temporary defensive measure,  the fund could shift up to 50% of assets
into  investments  such as money market  securities.  This could prevent losses,
but,  while  engaged in a  temporary  defensive  position,  the fund will not be
pursuing its investment objective.  However, portfolio management may choose not
to use these strategies for various reasons, even in volatile market conditions.

The following information supplements the disclosure under "Policies about
Transactions" in the "Policies You Should Know About" section of the fund's
prospectuses:

Redemption fees. The fund imposes a redemption fee of 2% of the total redemption
amount (calculated at net asset value, without regard to the effect of any
contingent deferred sales charge; any contingent deferred sales charge is also
assessed on the total redemption amount without regard to the assessment of the
2% redemption fee) on all fund shares redeemed or exchanged within 15 days of
buying them (either by purchase or exchange). The redemption fee is paid
directly to the fund and is designed to encourage long-term investment and to
off-set transaction and other costs associated with short-term or excessive
trading. For purposes of determining whether the redemption fee applies, shares
held the longest time will be treated as being redeemed first and shares held
the shortest time will be treated as being redeemed last.

The redemption fee is applicable to fund shares purchased either directly or
through a financial intermediary, such as a broker-dealer. Transactions through
financial intermediaries typically are placed with the fund on an omnibus basis
and include both purchase and sale transactions placed on behalf of multiple
investors. These purchase and sale transactions are generally netted against one
another and placed on an aggregate basis; consequently the identities of the
individuals on whose behalf the transactions are placed generally are not known
to the fund. For this reason, the fund has undertaken to notify financial
intermediaries of their obligation to assess the redemption fee on customer
accounts and to collect and remit the proceeds to the fund. However, due to
operational requirements, the intermediaries' methods for tracking and
calculating the fee may be inadequate or differ in some respects from the
fund's. Subject to approval by the Advisor or the fund's Board, intermediaries
who transact business on an omnibus basis may implement the redemption fees
according to their own operational guidelines (which may be different than the
fund's policies) and remit the fees to the fund.

The redemption fee will not be charged in connection with the following exchange
or redemption transactions: (i) transactions on behalf of participants in
certain research wrap programs; (ii) transactions on behalf of a shareholder to
return any excess IRA contributions to the shareholder; (iii) transactions on
behalf of a shareholder to effect a required minimum distribution on an IRA;
(iv) transactions on behalf of any mutual fund advised by the Advisor and its
affiliates (e.g., "funds of funds") or, in the case of a master/feeder
relationship, redemptions by the feeder fund from the master portfolio; (v)
transactions on behalf of certain unaffiliated mutual funds operating as funds
of funds; (vi) transactions following death or disability of any registered
shareholder, beneficial owner or grantor of a living trust with respect to
shares purchased before death or disability; (vii) transactions involving
hardship of any registered shareholder; (viii) systematic transactions with
pre-defined trade dates for purchases, exchanges or redemptions, such as
automatic account rebalancing, or loan origination and repayments; (ix)
transactions involving shares purchased through the reinvestment of dividends or
other distributions; (x) transactions involving shares transferred from another
account in the same fund or converted from another class of the same fund (the
redemption fee period will carry over to the acquired shares); (xi) transactions
initiated by the fund or administrator (e.g., redemptions for not meeting
account minimums, to pay account fees funded by share redemptions, or in the
event of the liquidation or merger of the fund); or (xii) transactions in cases
when there are legal or contractual limitations or restrictions on the
imposition of the redemption fee (as determined by the fund or its agents in
their sole discretion). It is the policy of the DWS funds to permit approved
fund platform providers to execute transactions in shares of the funds without
the imposition of a redemption fee if such providers have implemented
alternative measures that are determined by the Advisor to provide controls on
short-term and excessive trading that are comparable to the DWS funds' policies.
