                             DWS Equity Income Fund

The Board of each fund noted below has given preliminary approval to a proposal
by Deutsche Investment Management Americas Inc. ("DIMA"), the advisor of each
such fund, to effect the following fund merger:

--------------------------------------------------------------------------------
Acquired Fund                             Acquiring Fund
--------------------------------------------------------------------------------
DWS Equity Income Fund                    DWS Large Cap Value Fund
--------------------------------------------------------------------------------

Completion of this merger is subject to, among other things: (i) final approval
by the Board of each fund, and (ii) approval by shareholders of the Acquired
Fund. Prior to the shareholder meeting, shareholders of record on the record
date of the Acquired Fund will receive (i) a Proxy Statement/Prospectus
describing in detail the proposed merger and the Board's considerations in
recommending that shareholders approve the merger, (ii) a proxy card and
instructions on how to submit a vote, and (iii) a Prospectus for the Acquiring
Fund.

If the proposed merger is approved by shareholders, the Acquired Fund will be
closed to new investors except as described below. Unless you fit into one of
the investor eligibility categories described below, you may not invest in the
fund following shareholder approval of the merger.

You may continue to purchase fund shares following shareholder approval through
your existing fund account and reinvest dividends and capital gains if, as of
4:00 p.m. Eastern time on the shareholder meeting date, or such later date as
shareholder approval may occur, you are:

o  a current fund shareholder; or

o  a participant in any group retirement, employee stock bonus, pension or
   profit sharing plan that offers the fund as an investment option.
