SUPPLEMENT TO THE CURRENTLY EFFECTIVE PROSPECTUS:

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

                    Tax-Exempt California Money Market Fund


The following information supplements the disclosure in the "Other Policies and
Risks" section of the fund's prospectus: The fund may also post on the Web site,
on a more frequent basis, a percentage breakdown of the holdings of the fund by
type of security.


The following information replaces similar disclosure in the "Policies about
transactions -- Transaction Processing" section of the fund's prospectus:

Transaction Processing. Orders for the purchase of shares by wire transfer will
normally be effective at the share price next computed after receipt of the wire
transfer of the amount to be invested. If a wire transfer purchase order is
received in good order before 12:00 p.m. Eastern time, it will normally receive
the dividend for that day.

Shareholders known to the fund may notify the transfer agent in advance of their
wire transfer purchase by calling the transfer agent prior to the 12:00 p.m.
Eastern time cut-off time and providing the amount of the order. The investor
will receive a confirmation number for the trade. If the fund receives the wire
transfer before the close of the Federal Funds wire system, the trade will be
entitled to that day's dividend. If the fund does not receive the wire transfer
by the close of the Federal Funds wire system, the trade may not receive the
dividend for that day and, depending upon the circumstances, the trade may
receive the dividend for the following business day or may be canceled or
rejected and, in any case, the investor may be charged for any losses or fees
that result, which may be paid by deductions from their account or otherwise.
The fund's Distributor may refuse to allow any investor to trade with the fund
in this manner and may require that the wire transfer of purchase proceeds be
received before the trade is considered in good order.

Investments by check will be effective on the business day following receipt and
will earn dividends the following business day. If you pay for shares by check
and the check fails to clear, we have the right to cancel your order, hold you
liable or charge you or your account for any losses or fees the fund or its
agents have incurred.

Orders processed through dealers or other financial services firms via Fund/SERV
will be effected at the share price calculated on the trade day (normally the
date the order is received). Purchases processed via Fund/SERV will begin
earning dividends on the day the fund receives the payment (typically the next
business day). For redemptions processed via Fund/SERV, you generally will
receive dividends accrued up to, but not including, the business day that
payment for your shares is made.

When selling shares, shareholders generally receive dividends up to, but not
including, the business day following the day on which the shares were sold. To
sell shares, you must state whether you would like to receive the proceeds by
wire or check.

In order to receive the proceeds by wire, contact the transfer agent before
12:00 p.m. Eastern time. After you inform the transfer agent of the amount of
your redemption, you will receive a trade confirmation number. If the fund
receives a sell request before 12:00 p.m. Eastern time and the request calls for
proceeds to be sent out by wire, the proceeds will normally be wired on the same
day. However, the shares sold will not earn that day's dividend.

As noted elsewhere in the prospectus, proceeds of a redemption may be delayed.
The ability to receive "same day" wire redemption proceeds can be affected by a
variety of circumstances including the time that the request is made, the level
of redemption requests and purchase orders and general market conditions.
Requests for same day wire that are received earlier in the day will be given
priority over requests received later in the day in the event that it is
necessary to limit the amount of same day wire redemptions.

The following information replaces similar disclosure in the "How the fund
calculates share price" section of the fund's prospectus:

The fund is open for business each day the New York Stock Exchange (the
"Exchange") is open. Normally, the fund calculates its share price once every
business day as of the close of regular trading on the Exchange (typically 4:00
p.m. Eastern time, but sometimes earlier, as in the case of scheduled half-day
trading or unscheduled suspensions of trading). In the event of scheduled
partial day trading or unscheduled suspensions of trading on the Exchange, the
calculation of share price shall be as of the close of trading on the Exchange.
In such instances, the latest time for receipt of wire purchase transactions
entitled to receive same day dividend treatment and for receipt of redemption
orders for same day wire transfer of proceeds will be the earlier of (a) 12:00
p.m. Eastern time or (b) the early closing time of the Exchange. The fund seeks
to maintain a stable $1.00 share price.

The fund may, but is not required to, accept certain types of purchase and
redemption orders (not including exchanges) on days that the Exchange is closed,
or beyond an Exchange early closing time (referred to as a "Limited Trading
Period") if: (a) the Federal Reserve system is open, (b) the primary trading
markets for the fund's portfolio instruments are open and (c) the Advisor
believes there will be adequate liquidity in the short-term markets. During any
such Limited Trading Period, the fund will only accept purchase orders by wire
with advance telephone notification and telephone redemption orders with
proceeds to be sent by wire, ACH or check and will not accept orders by any
other means. (Automated Telephone Line orders are not permitted.) If redemption
proceeds are requested by ACH or check, the transmission of the ACH payment or
the mailing of the check, as the case may be, will be delayed by at least one
business day in comparison to normal trading periods. Orders submitted by other
means will be processed on the next day that the Exchange is open. The
calculation of share price will be as set forth in the prospectus for normal
trading days. Orders must be submitted by the cut-off times for receipt of wire
purchases entitled to that day's dividend and for receipt of telephone
redemption orders for same day wire transfer, which will be the earlier of: (a)
the times set forth in the prospectus for normal trading days or (b) such
earlier times that the fund determines based on the criteria described above. If
redemption proceeds are requested by ACH or check, orders must be received prior
to the calculation of share price. Please call (877) 237-1131 or visit our Web
site at www.dws-scudder.com for additional information about whether the

fund will be open for business on a particular day.
Information concerning the intention of the fund to be open for a Limited
Trading Period will be available at least one business day prior to the
applicable day that the Exchange is closed or is closing early in the case of
scheduled closings and as soon as practical in the case of unscheduled closings.
