Portfolio Management Review

In the following interview, the portfolio management team discusses
the market environment and the team's approach to managing
DWS Money Market Prime Series during the fund's most recent
semiannual period ended January 31, 2009.

The views expressed in the following discussion reflect those of the portfolio management
team only through the end of the period of the report as stated on the cover. The management
team's views are subject to change at any time based on market and other conditions and
should not be construed as a recommendation. Past performance is no guarantee of future
results. Current and future portfolio holdings are subject to risk.

Q: Will you discuss the market environment for money market
funds during the most recent six-month period?

A:Over the past six months, we continued to witness
unprecedented events in both the money markets and financial
markets worldwide. The massive credit crunch that originated with
problems in the US subprime mortgage market as well as
securitized mortgages brought down several financial firms and
essentially transformed Wall Street. Among other unprecedented
actions, the US government placed Federal National Mortgage
Association (Fannie Mae) and Federal Home Loan Mortgage
Corporation (Freddie Mac) in conservatorship of a newly created
independent regulator, the Federal Housing Finance Agency, and
injected billions into the banking system through the Troubled
Assets Relief Program (TARP).

Within the money market fund industry, major losses caused by the
liquidity squeeze and the collapse of Lehman Brothers forced one
money fund's share price to drop below $1 and another money fund
to close. In the general "flight to quality" that ensued  amid a
market atmosphere of heightened uncertainty over perceived credit
quality  demand for short-term Treasury securities reached
overwhelming levels on several occasions as investors prized safety
over all other considerations, including yield.1 In response to the
freeze-up in money market liquidity, the US Federal Reserve Board
(the Fed) created new lending facilities for commercial paper,
asset-backed commercial paper and the money markets.2 In the
fourth quarter, short-term credit market conditions improved
somewhat in response to government actions. However, many
investors clung to a flight-to-quality stance in light of rising
unemployment, trouble for US automakers, the need for more Wall
Street bailouts and concern that the recession and problems in the
housing market could go on for some time. In December, the Fed
reduced short-term interest rates to a target between 0% and
0.25%, saying that it would now expand its balance sheet in an
attempt to stimulate the financial markets. Following the January
Federal Open Market Committee (FOMC) meeting, the Fed restated
its ability and willingness to employ all available tools to promote
economic growth as well as price stability.

As of January 31, 2009, three-month LIBOR, an industry standard
for measuring three-month taxable money market rates, stood at
1.18%, compared with 2.79% as of July 31, 2008.3

Performance is historical and does not guarantee future results. Current
performance may be lower or higher than the performance data quoted. An
investment in a money market fund is not insured or guaranteed by the Federal
Deposit Insurance Corporation or any other government agency. Although money
market funds seek to preserve the value of your investment at $1.00 per share, it is
possible to lose money by investing in them.

7-day current yield refers to the income paid by the portfolios over a 7-day period
expressed as an annual percentage rate. For the most current yield information,

Q: In light of market conditions during the period, what has been
the strategy for this fund?

A:Given the difficult situation throughout the investment markets,
and understanding that the credit crunch would not be a short-term
phenomenon, our strategy at the start of the six-month period was
to emphasize liquidity and high credit quality while looking for ways
to maximize yield potential when opportunities presented
themselves. In mid-September, when conditions in the money
markets worsened drastically, we enacted a significantly more
defensive strategy, holding more overnight securities in the form of
repurchase agreements. We also purchased Treasury and agency
instruments as well as corporate commercial paper and sovereign
securities (direct issuance by foreign governments) in seeking the
highest-quality portfolio given the extremely difficult market
conditions. As conditions have now eased somewhat, we have
extended the fund's average maturity utilizing the highest-quality
securities.

Q: What detracted from performance during the period?

A:The types of securities in which the fund was investing tended
to have lower yields than issues carrying more risk. We preferred to
be cautious during this time of significant market turbulence. In the
end, this cost the fund some yield, but we believe that this
represented a prudent approach to preserving principal.

Q: Will you describe your investment philosophy?

A:We continue to insist upon the highest credit quality. We also
continue to apply a careful approach to investing on behalf of the
fund and to seek competitive yield for our shareholders.

Information About Your Fund's Expenses

As an investor, you incur two types of costs: ongoing expenses and
transaction costs. Ongoing expenses include management fees, distribution
and service (12b-1) fees and other Fund expenses. Examples of transaction
costs include account maintenance fees, which are not shown in this
section. The following tables are intended to help you understand your
ongoing expenses (in dollars) of investing in the Fund and to help you
compare these expenses with the ongoing expenses of investing in other
mutual funds. In the most recent six-month period, the Fund limited these
expenses for DWS Cash Investment Trust Class B and DWS Cash
Investment Trust Class C; had it not done so, expenses would have been
higher. The example in the table is based on an investment of $1,000
invested at the beginning of the six-month period and held for the entire
period(August 1, 2008 to January 31, 2009).

The tables illustrate your Fund's expenses in two ways:

•   Actual Fund Return. This helps you estimate the actual dollar amount of
ongoing expenses (but not transaction costs) paid on a $1,000
investment in the Fund using the Fund's actual return during the period.
To estimate the expenses you paid over the period, simply divide your
account value by $1,000 (for example, an $8,600 account value divided
by $1,000 = 8.6), then multiply the result by the number in the
"Expenses Paid per $1,000" line under the share class you hold.

•   Hypothetical 5% Fund Return. This helps you to compare your Fund's
ongoing expenses (but not transaction costs) with those of other mutual
funds using the Fund's actual expense ratio and a hypothetical rate of
return of 5% per year before expenses. Examples using a 5%
hypothetical fund return may be found in the shareholder reports of other
mutual funds. The hypothetical account values and expenses may not be
used to estimate the actual ending account balance or expenses you
paid for the period.

Please note that the expenses shown in these tables are meant to highlight
your ongoing expenses only and do not reflect any transaction costs. The
"Expenses Paid per $1,000" line of the tables is useful in comparing
ongoing expenses only and will not help you determine the relative total
expense of owning different funds. An account maintenance fee of $6.25
per quarter for DWS Cash Investment Trust Class S may apply for certain
accounts whose balances do not meet the applicable minimum initial
investment. This fee is not included in these tables. If it was, the estimate
of expenses paid for DWS Cash Investment Trust Class S during the period
would be higher, and account value during the period would be lower, by
this amount.

Fair Value Measurements

Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157,
"Fair Value Measurements," establishes a three-tier hierarchy for measuring fair value and
requires additional disclosure about the classification of fair value measurements.

Various inputs are used in determining the value of the Fund's investments. These inputs are
summarized in three broad levels. Level 1 includes quoted prices in active markets for identical
securities. Level 2 includes other significant observable inputs (including quoted prices for
similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes
significant unobservable inputs (including the Fund's own assumptions in determining the fair
value of investments). The inputs or methodology used for valuing securities are not
necessarily an indication of the risk associated with investing in those securities. Securities
held by a money market fund are reflected as Level 2 because the securities are valued at
amortized cost (which approximates fair value) and, accordingly, the inputs used to determine
value are not quoted prices in an active market.

The following is a summary of the inputs used as of January 31, 2009 in valuing the Fund's
investments. For information on the Fund's policy regarding the valuation of investments,
please refer to the Security Valuation section of Note A in the accompanying Notes to the
Financial Statements.

|Valuation Inputs | Investments in
Securities

|Level 1          | $                       
|Level 2          | 3,725,058,123

Notes to Financial Statements(Unaudited)

A. Significant Accounting Policies

DWS Money Market Prime Series (the "Fund") is a diversified series of
DWS Money Funds (the "Trust") which is registered under the Investment
Company Act of 1940, as amended (the "1940 Act"), as an open-end,
diversified management investment company organized as a Massachusetts
business trust.

The Fund offers multiple classes of shares which provide investors with
different purchase options: DWS Cash Investment Trust Classes A, B, C, S
and DWS Money Market Fund shares. DWS Cash Investment Trust Class A
shares are offered to investors without an initial sales charge but are subject
to the applicable sales charge if exchanged into Class A shares of another
DWS Investments Fund. DWS Cash Investment Trust Class B shares are
offered to investors without an initial sales charge but are subject to higher
ongoing expenses than DWS Cash Investment Trust Class A shares and a
contingent deferred sales charge payable upon certain redemptions. DWS
Cash Investment Trust Class B shares automatically convert to DWS Cash
Investment Trust Class A shares six years after issuance. DWS Cash
Investment Trust Class C shares are offered to investors without an initial
sales charge but are subject to higher ongoing expenses than DWS Cash
Investment Trust Class A shares and a contingent deferred sales charge
payable upon certain redemptions within one year of purchase. DWS Cash
Investment Trust Class C shares do not automatically convert into another
class. DWS Money Market Fund and DWS Cash Investment Trust Class S
shares are not subject to initial or contingent deferred sales charges. DWS
Cash Investment Trust Class S shares are generally not available to new
investors except under certain circumstances.

Investment income, realized gains and losses, and certain fund-level
expenses and expense reductions, if any, are borne pro rata on the basis of
relative net assets by the holders of all classes of shares, except that each
class bears certain expenses unique to that class such as distribution and
service fees, services to shareholders and certain other class-specific
expenses. Differences in class-level expenses may result in payment of
different per share dividends by class. All shares of the Fund have equal
rights with respect to voting subject to class-specific arrangements.

The Fund's financial statements are prepared in accordance with accounting
principles generally accepted in the United States of America, which require
the use of management estimates. Actual results could differ from those
estimates. The policies described below are followed consistently by the
Fund in the preparation of their financial statements.

Security Valuation. Portfolio securities are valued utilizing the amortized
cost method permitted in accordance with Rule 2a-7 under the 1940 Act and
certain conditions therein. Under this method, which does not take into
account unrealized capital gains or losses on securities, an instrument is
initially valued at its cost and thereafter assumes a constant
accretion/amortization rate to maturity of any discount or premium.

The Fund adopted Financial Accounting Standards Board ("FASB")
Statement of Financial Accounting Standards No. 157, "Fair Value
Measurements," effective at the beginning of the Fund's fiscal year.
Disclosure about the classification of fair value measurements is included at
the end of the Fund's Investment Portfolio.

Repurchase Agreements. The Fund may enter into repurchase agreements
with certain banks and broker/dealers whereby the Fund, through its
custodian or sub-custodian bank, receives delivery of the underlying
securities, the amount of which at the time of purchase and each
subsequent business day is required to be maintained at such a level that
the market value is equal to at least the principal amount of the repurchase
price plus accrued interest. The custodian bank holds the collateral in a
separate account until the agreement matures. If the value of the securities
falls below the principal amount of the repurchase agreement plus accrued
interest, the financial institution deposits additional collateral by the
following business day. If the financial institution either fails to deposit the
required additional collateral or fails to repurchase the securities as agreed,
the Fund has the right to sell the securities and recover any resulting loss
from the financial institution. If the financial institution enters into
bankruptcy, the Fund's claims on the collateral may be subject to legal
proceedings.

Federal Income Taxes. The Fund's policy is to comply with the requirements
of the Internal Revenue Code, as amended, which are applicable to
regulated investment companies, and to distribute all of its taxable income
to its shareholders.

At July 31, 2008, the Fund had a net tax basis capital loss carry forward of
approximately $143,000 which may be applied against any realized net
taxable capital gains of each succeeding year until fully utilized or until
July 31, 2016, whichever occurs first. In addition from November 1, 2007
through July 31, 2008, the Fund incurred approximately $109,000 of net
realized capital losses. As permitted by tax regulations, the Fund intends to
elect to defer these losses and treat them as arising in the fiscal year ending
July 31, 2009.

The Fund has reviewed the tax positions for the open tax years as of
July 31, 2008 and has determined that no provision for income tax is
required in the Fund's financial statements. The Fund's federal tax returns
for the prior three fiscal years remain subject to examination by the Internal
Revenue Service.

Distribution of Income and Gains. Net investment income of the Fund is
declared as a daily dividend and is distributed to shareholders monthly. The
Fund may take into account capital gains and losses in its daily dividend
declarations. The Fund may also make additional distributions for tax
purposes if necessary.

Permanent book and tax basis differences relating to shareholder
distributions will result in reclassifications to paid in capital. Temporary book
and tax basis differences will reverse in a subsequent period. There were no
significant book-to-tax differences for the Fund.

The tax character of current year distributions will be determined at the end
of the current fiscal year.

Contingencies. In the normal course of business, the Fund may enter into
contracts with service providers that contain general indemnification
clauses. The Fund's maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the
Fund that have not yet been made. However, based on experience, the Fund
expects the risk of loss to be remote.

Other. Investment transactions are accounted for on trade date. Interest
income is recorded on the accrual basis. Realized gains and losses from
investment transactions are recorded on an identified cost basis. All
discounts and premiums are accreted/amortized for both tax and financial
reporting purposes.

B. Related Parties

Management Agreement. Under the Investment Management Agreement
with Deutsche Investment Management Americas Inc. ("DIMA" or the
"Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the
Advisor directs the investments of the Fund in accordance with their
investment objectives, policies and restrictions. The Advisor determines the
securities, instruments and other contracts relating to investments to be
purchased, sold or entered into by the Fund.

Under the Investment Management Agreement with the Advisor, the Fund
pays a monthly management fee based on the Fund's average daily net
assets, computed and accrued daily and payable monthly, at the following
annual rates:

|First $215,000,000 of the Fund's average daily net assets | .400%
|--------------------------------------------------------- | -----
|Next $335,000,000 of such net assets                      | .275%
|Next $250,000,000 of such net assets                      | .200%
|Next $800,000,000 of such net assets                      | .150%
|Next $800,000,000 of such net assets                      | .140%
|Next $800,000,000 of such net assets                      | .130%
|Over $3,200,000,000 of such net assets                    | .120%

Accordingly, for the six months ended January 31, 2009, the fee pursuant to
the Investment Management Agreement was equivalent to an annualized
effective rate of 0.17% of the Fund's average daily net assets.

For the period from August 1, 2008 through March 9, 2010, the Advisor has
contractually agreed to waive all or a portion of its management fee and
reimburse or pay certain operating expenses to the extent necessary to
maintain total operating expenses of certain classes of the Fund (excluding
certain expenses such as extraordinary expenses, taxes, brokerage and
interest) as follows:

|DWS Cash Investment Trust Class A | .96% 
|--------------------------------- | -----
|DWS Cash Investment Trust Class B | 1.67%
|DWS Cash Investment Trust Class C | 1.60%
|DWS Money Market Fund             | .47% 

For DWS Cash Investment Trust Class S shares, for the period from August
1, 2008 through September 30, 2009, the Advisor had contractually agreed
to waive all or a portion of its management fee and reimburse or pay certain
operating expenses (excluding certain expenses such as extraordinary
expenses, taxes, brokerage and interest) to the extent necessary to
maintain total operating expenses at 0.67% of the Fund's average daily net
assets.

For DWS Cash Investment Trust Class S shares, for the period from October
1, 2009 through March 9, 2010, the Advisor has contractually agreed to
waive all or a portion of its management fee and reimburse or pay certain
operating expenses (excluding certain expenses such as extraordinary
expenses, taxes, brokerage and interest) to the extent necessary to
maintain total operating expenses at 0.72% of the Fund's average daily net
assets.

In addition, the Advisor has agreed to voluntarily waive expenses as
necessary to maintain a minimum yield. The waiver may be changed or
terminated at any time without notice. Under these arrangements, the
Advisor waived certain shareholder service fees shown below on DWS Cash
Investment Trust Class B and DWS Cash Investment Trust Class C.

Administration Fee. Pursuant to an Administrative Services Agreement,
DIMA provides most administrative services to the Fund. For all services
provided under the Administrative Services Agreement, the Fund pays the
Advisor an annual fee ("Administration Fee") of 0.10% of the Fund's average
daily net assets, computed and accrued daily and payable monthly. For the
six months ended January 31, 2009, the Advisor received an Administration
Fee of $1,971,373, of which $314,732 is unpaid.

Service Provider Fees. DWS Investments Service Company ("DISC"), an
affiliate of the Advisor, is the transfer agent, dividend-paying agent and
shareholder service agent for the Fund. Pursuant to a sub-transfer agency
agreement among DISC and DST Systems, Inc. ("DST"), DISC has
delegated certain transfer agent, dividend-paying agent and shareholder
service agent functions to DST. DISC compensates DST out of the
shareholder servicing fee it receives from the Fund. For the six months
ended January 31, 2009, the amounts charged to the Fund by DISC were as

Fund may borrow for temporary or emergency purposes, including the
meeting of redemption requests that otherwise might require the untimely
disposition of securities. The Participants are charged an annual
commitment fee which is allocated based on net assets, among each of the
Participants. Interest is calculated at the Federal Funds Rate plus
0.35 percent. The Fund may borrow up to a maximum of 33 percent of its
net assets under the agreement.

F. Participation in the Treasury's Temporary Guarantee Program

The Fund is participating in the Temporary Guarantee Program for Money
Market Funds (the "Program") established by the U.S. Department of the
Treasury (the "Treasury").

The Program is designed to protect the value of accounts in the Fund as of
the close of business on September 19, 2008. According to the terms of the
Program, any investment made by a shareholder after September 19, 2008
in excess of the amount held in the account as of the close of business on
that date will not be covered by the Program. Any purchase of shares of the
Fund for an account opened after September 19, 2009 will also not be
covered under the Program. The Program guarantee will apply to the lesser
of (i) the number of shares held in an account as of the close of business on
September 19, 2008, or (ii) the number of shares held in the account on the
date the Program guarantee is triggered. Subject to certain conditions and
limitations, the Program guarantee is triggered if the Funds' net asset values
fall below $0.995 and the Fund is liquidated. Guarantee payments under the
Program will not exceed the amount available within the Treasury's
Exchange Stabilization Fund ("ESF") on the date of payment.

The Fund bears the expenses of participating in the Program. The expense
is determined by the product of (i) the number of shares outstanding of each
class as of September 19, 2008 valued at $1.00; and (ii) the applicable
Program participation fee rate, which is based upon the market-based net
asset value outstanding of each share class as of September 19, 2008. For
the initial period ending December 18, 2008, the Program participation fee
was equal to 0.010%. For the coverage under the Program beginning on
December 19, 2008 and ending on April 30, 2009, the Program participation
fee is equal to 0.015%. This expense is being amortized over the length of
the participation in the Program and is included on the Statement of
Operations. Through January 31, 2009, the Fund has accrued $615,053. The
Program is set to terminate on April 30, 2009, unless extended by the
Treasury. The Treasury may extend the program through the close of
business on September 18, 2009. If the Program is extended beyond April
30, 2009, the Fund would need to pay an additional fee and there can be no
assurances that the Fund would continue to participate. This expense is
borne by the Fund without regard to any expense limitation currently in
effect for the Fund.

Neither the Fund nor Deutsche Investment Management Americas Inc., the
Fund's investment advisor, are in any manner approved, endorsed,
sponsored or authorized by the Treasury.

Investment Management Agreement
Approval

The Board of Trustees, including the Independent Trustees, approved
the renewal of your Fund's investment management agreement (the
"Agreement") with Deutsche Investment Management Americas Inc.
("DIMA") in September 2008.

In terms of the process that the Board followed prior to approving the
Agreement, shareholders should know that:

•   At the present time, all but one of your Fund's Trustees are independent
of DIMA and its affiliates.

•   The Trustees meet frequently to discuss fund matters. Each year, the
Trustees dedicate part or all of several meetings to contract review
matters. Over the course of several months, the Board's Contract
Committee, in coordination with the Board's Fixed Income and Quant
Oversight Committee, reviewed comprehensive materials received from
DIMA, independent third parties and independent counsel. These
materials included an analysis of the Fund's performance, fees and
expenses, and profitability compiled by the Fund's independent fee
consultant. The Board also received extensive information throughout
the year regarding performance of the Fund.

•   The Independent Trustees regularly meet privately with their
independent counsel (and, as needed, other advisors) to discuss contract
review and other matters. In addition, the Independent Trustees were
also advised by the Fund's independent fee consultant in the course of
their review of the Fund's contractual arrangements and considered a
comprehensive report prepared by the independent fee consultant in
connection with their deliberations (the "IFC Report").

•   In connection with reviewing the Agreement, the Board also reviewed
the terms of the Fund's Rule 12b-1 plan, distribution agreement,
administrative services agreement, transfer agency agreement and other
material service agreements.

•   Based on its evaluation of the information provided, the Contract
Committee presented its findings and recommendations to the
Independent Trustees as a group. The Independent Trustees reviewed
the Contract Committee's findings and recommendations and presented
their recommendations to the full Board.

In connection with the contract review process, the Contract Committee
and the Board considered the factors discussed below, among others.
The Board also considered that DIMA and its predecessors have managed
the Fund since its inception, and the Board believes that a long-term
relationship with a capable, conscientious advisor is in the best interests of
the Fund. The Board considered, generally, that shareholders chose to invest
or remain invested in the Fund knowing that DIMA managed the Fund, and
that the Agreement was approved by the Fund's shareholders at a special
meeting held in 2008. DIMA is part of Deutsche Bank, a major global
banking institution that is engaged in a wide range of financial services. The
Board believes that there are significant advantages to being part of a global
asset management business that offers a wide range of investing expertise
and resources, including hundreds of portfolio managers and analysts with
research capabilities in many countries throughout the world.

While shareholders may focus primarily on fund performance and fees, the
Fund's Board considers these and many other factors, including the quality
and integrity of DIMA's personnel and such other issues as back-office
operations, fund valuations, and compliance policies and procedures.

Nature, Quality and Extent of Services. The Board considered the terms of
the Agreement, including the scope of advisory services provided under the
Agreement. The Board noted that, under the Agreement, DIMA provides
portfolio management services to the Fund and that, pursuant to a separate
administrative services agreement, DIMA provides administrative services
to the Fund. The Board considered the experience and skills of senior
management and investment personnel, the resources made available to
such personnel, the ability of DIMA to attract and retain high-quality
personnel, and the organizational depth and stability of DIMA. The Board
reviewed the Fund's performance over short-term and long-term periods and
compared those returns to various agreed-upon performance measures,
including a peer universe compiled by the independent fee consultant using
information supplied by iMoneyNet Inc. ("iMoneyNet"). The Board also
noted that it has put a process into place of identifying "Focus Funds" (e.g.,
funds performing poorly relative to their benchmark or a peer group
compiled by Lipper Inc. ("Lipper")), and receives more frequent reporting
and information from DIMA regarding such funds, along with DIMA's
remedial plans to address underperformance. The Board believes this
process is an effective manner of identifying and addressing
underperforming funds. Based on the information provided, the Board noted
that for the one-, three- and five-year periods ended December 31, 2007, the
Fund's performance (DWS Money Market Fund shares) was in the 2nd
quartile of the applicable iMoneyNet universe (the 1st quartile being the
best performers and the 4th quartile being the worst performers).

On the basis of this evaluation and the ongoing review of investment results
by the Board, the Board concluded that the nature, quality and extent of
services provided by DIMA historically have been and continue to be
satisfactory.

Fees and Expenses. The Board considered the Fund's investment
management fee schedule, operating expenses, and total expense ratios,
and comparative information provided by Lipper and the independent
fee consultant regarding investment management fee rates paid to other
investment advisors by similar funds (1st quartile being the most favorable
and 4th quartile being the least favorable). With respect to management
fees paid to other investment advisors by similar funds, the Board noted that
the contractual fee rates paid by the Fund, which include the 0.10% fee paid
to DIMA under the Fund's administrative services agreement, were lower
than the median (1st quartile) of the applicable Lipper peer group (based on
Lipper data provided as of December 31, 2007). Based on Lipper data
provided as of December 31, 2007, the Board noted that the Fund's total
(net) operating expenses (excluding 12b-1 fees and/or shareholder
administration fees) were expected to be higher than the median of the
applicable Lipper expense universe for the following share classes: DWS
Cash Investment Trust Class A shares (3rd quartile), DWS Cash Investment
Trust Class B shares (3rd quartile), DWS Cash Investment Trust Class C
shares (3rd quartile) and DWS Cash Investment Trust Class S shares (3rd
quartile), and lower than the median of the applicable Lipper expense
universe for the following share class: DWS Money Market Fund shares
(2nd quartile). The Board considered the Fund's management fee rate as
compared to fees charged by DIMA and certain of its affiliates for
comparable mutual funds and considered differences in fund and fee
structures between the DWS Funds. The Board also considered how the
Fund's total (net) operating expenses compared to the total (net) operating
expenses of a more customized peer group selected by Lipper (based on
such factors as asset size). The Board also noted that the expense
limitations agreed to by DIMA helped to ensure that the Fund's total (net)
operating expenses would be competitive relative to the applicable Lipper
universe.

On the basis of the information provided, the Board concluded that
management fees were reasonable and appropriate in light of the nature,
quality and extent of services provided by DIMA.

Profitability. The Board reviewed detailed information regarding revenues
received by DIMA under the Agreement. The Board considered the
estimated costs and pre-tax profits realized by DIMA from advising the DWS
Funds, as well as estimates of the pre-tax profits attributable to managing
the Fund in particular. The Board also received information regarding the
estimated enterprise-wide profitability of the DWS Investments organization
with respect to all fund services in totality and by fund. The Board reviewed
DIMA's methodology in allocating its costs to the management of the Fund.
Based on the information provided, the Board concluded that the pre-tax
profits realized by DIMA in connection with the management of the Fund
were not unreasonable. The Board also reviewed information regarding the
profitability of certain similar investment management firms. The Board
noted that while information regarding the profitability of such firms is
limited (and in some cases is not necessarily prepared on a comparable
basis), DIMA and its affiliates' overall profitability with respect to the DWS
Investments fund complex (after taking into account distribution and other
services provided to the funds by DIMA and its affiliates) was lower than the
overall profitability levels of many comparable firms for which such data was
available.

Economies of Scale. The Board considered whether there are economies of
scale with respect to the management of the Fund and whether the Fund
benefits from any economies of scale. The Board noted that the Fund's
management fee schedule includes fee breakpoints. The Board concluded
that the Fund's fee schedule represents an appropriate sharing between the
Fund and DIMA of such economies of scale as may exist in the
management of the Fund at current asset levels.

Other Benefits to DIMA and Its Affiliates. The Board also considered the
character and amount of other incidental benefits received by DIMA and its
affiliates, including any fees received by DIMA for administrative services
provided to the Fund and any fees received by an affiliate of DIMA for
distribution services. The Board also considered benefits to DIMA related to
brokerage and soft-dollar allocations, including allocating brokerage to pay
for research generated by parties other than the executing broker dealers,
which pertain primarily to funds investing in equity securities, along with the
incidental public relations benefits to DIMA related to DWS Funds
advertising and cross-selling opportunities among DWS Investments
products and services. The Board concluded that management fees were
reasonable in light of these fallout benefits.

Compliance. The Board considered the significant attention and resources
dedicated by DIMA to documenting and enhancing its compliance
processes in recent years. The Board noted in particular (i) the experience
and seniority of DIMA's chief compliance officer; (ii) the large number of
compliance personnel who report to DIMA's chief compliance officer; and (iii)
the substantial commitment of resources by DIMA and its affiliates to
compliance matters.

Based on all of the information considered and the conclusions reached, the
Board (including a majority of the Independent Trustees) determined that the
continuation of the Agreement is in the best interests of the Fund. In
making this determination the Board did not give particular weight to any
single factor identified above. The Board considered these factors over the
course of numerous meetings, certain of which were in executive session
with only the Independent Trustees and their counsel present. It is possible
that individual Trustees may have weighed these factors differently in
reaching their individual decisions to approve the continuation of the
Agreement.

Summary of Management Fee Evaluation by
Independent Fee Consultant

October 24, 2008

Pursuant to an Order entered into by Deutsche Investment Management
Americas and affiliates (collectively, "DeAM") with the Attorney General of
New York, I, Thomas H. Mack, have been appointed the Independent Fee
Consultant for the DWS Funds (formerly the DWS Scudder Funds). My
duties include preparing an annual written evaluation of the management
fees DeAM charges the Funds, considering among other factors the
management fees charged by other mutual fund companies for like
services, management fees DeAM charges other clients for like services,
DeAM's costs of supplying services under the management agreements
and related profit margins, possible economies of scale if a Fund grows
larger, and the nature and quality of DeAM's services, including fund
performance. This report summarizes my evaluation for 2008, including my
qualifications, the evaluation process for each of the DWS Funds,
consideration of certain complex-level factors, and my conclusions. I served
in substantially the same capacity in 2007.

Qualifications

For more than 35 years I have served in various professional capacities
within the investment management business. I have held investment
analysis and advisory positions, including securities analyst, portfolio
strategist and director of investment policy with a large investment firm. I
have also performed business management functions, including business
development, financial management and marketing research and analysis.

Since 1991, I have been an independent consultant within the asset
management industry. I have provided services to over 125 client
organizations, including investment managers, mutual fund boards, product
distributors and related organizations. Over the past ten years I have
completed a number of assignments for mutual fund boards, specifically
including assisting boards with management contract renewal.

I hold a Master of Business Administration degree, with highest honors,
from Harvard University and Master of Science and Bachelor of Science
(highest honors) degrees from the University of California at Berkeley. I am
an independent director and audit committee financial expert for two
closed-end mutual funds, serve on the board of directors of a private market
research company, and have served in various leadership and financial
oversight capacities with non-profit organizations.

Evaluation of Fees for each DWS Fund

My work focused primarily on evaluating, fund-by-fund, the fees charged to
each of the 129 Fund portfolios in the DWS Fund family. For each Fund, I
considered each of the key factors mentioned above, as well as any other
relevant information. In doing so I worked closely with the Funds'
Independent Directors in their annual contract renewal process, as well as in
their approval of contracts for several new funds (documented separately).

In evaluating each Fund's fees, I reviewed comprehensive materials provided
by or on behalf of DeAM, including expense information prepared by Lipper
Analytical, comparative performance information, profitability data, manager
histories, and other materials. I also accessed certain additional information
from the Lipper, Strategic Insight, and Morningstar databases and drew on
my industry knowledge and experience.

To facilitate evaluating this considerable body of information, I prepared for
each Fund a document summarizing the key data elements in each area as
well as additional analytics discussed below. This made it possible to
consider each key data element in the context of the others.

In the course of contract renewal, DeAM agreed to implement a number of
fee and expense adjustments requested by the Independent Directors
which will favorably impact future fees and expenses, and my evaluation
includes the effects of these changes.

Fees and Expenses Compared with Other Funds

The competitive fee and expense evaluation for each fund focused on two
primary comparisons:

The Fund's contractual management fee (the advisory fee plus the
administration fee where applicable) compared with those of a group
of typically 12-15 funds in the same Lipper investment category
(e.g. Large Capitalization Growth) having similar distribution arrangements
and being of similar size.

The Fund's total expenses compared with a broader universe of funds
from the same Lipper investment category and having similar distribution
arrangements.

These two comparisons provide a view of not only the level of the fee
compared with funds of similar scale but also the total expense the Fund
bears for all the services it receives, in comparison with the investment
choices available in the Fund's investment category and distribution channel.
The principal figure-of-merit used in these comparisons was the subject
Fund's percentile ranking against peers.

DeAM's Fees for Similar Services to Others

DeAM provided management fee schedules for all of its US domiciled fund
and non-fund investment management accounts in any of the investment
categories where there is a DWS Fund. These similar products included the
other DWS Funds, non-fund pooled accounts, institutional accounts and
sub-advisory accounts. Using this information, I calculated for each Fund the
fee that would be charged to each similar product, at the subject Fund's
asset level.

Evaluating information regarding non-fund products is difficult because there
are varying levels of services required for different types of accounts, with
mutual funds generally requiring considerably more regulatory and
administrative types of service as well as having more frequent cash flows
than other types of accounts. Also, while mutual fund fees for similar fund
products can be expected to be similar, there will be some differences due
to different pricing conditions in different distribution channels (e.g. retail
funds versus those used in variable insurance products), differences in
underlying investment processes and other factors.

Costs and Profit Margins

DeAM provided a detailed profitability analysis for each Fund. After making
some adjustments so that the presentation would be more comparable to
the available industry figures, I reviewed profit margins from investment
management alone, from investment management plus other fund services
(excluding distribution) provided to the Funds by DeAM (principally
shareholder services), and DeAM profits from all sources, including
distribution. A later section comments on overall profitability.

Economies of Scale

Economies of scale  an expected decline in management cost per dollar
of fund assets as fund assets grow  are very rarely quantified and
documented because of inherent difficulties in collecting and analyzing
relevant data. However, in virtually every investment category that I
reviewed, larger funds tend to have lower fees and lower total expenses
than smaller funds. To see how each DWS Fund compares with this industry
observation, I reviewed:

The trend in Fund assets over the last five years and the accompanying
trend in total expenses. This shows if the Fund has grown and, if so,
whether total expense (management fees as well as other expenses)
have declined as a percent of assets.

Whether the Fund has break-points in its management fee schedule, the
extent of the fee reduction built into the schedule and the asset levels
where the breaks take effect, and in the case of a sub-advised Fund how
the Fund's break-points compare with those of the sub-advisory fee
schedule.

How the Fund's contractual fee schedule compares with trends in the
industry data. To accomplish this, I constructed a chart showing how
actual latest-fiscal-year contractual fees of the Fund and of other similar
funds relate to average fund assets, with the subject Fund's contractual
fee schedule superimposed.

Quality of Service  Performance

The quality-of-service evaluation focused on investment performance, which
is the principal result of the investment management service. Each Fund's
performance was reviewed over the past 1, 3, 5 and 10 years, as applicable,
and compared with that of other funds in the same investment category and
with a suitable market index.

In addition, I calculated and reviewed risk-adjusted returns relative to an
index of similar mutual funds' returns and a suitable market index. The
risk-adjusted returns analysis provides a way of determining the extent to
which the Fund's return comparisons are mainly the product of investment
value-added (or lack thereof) or alternatively taking considerably more or less
risk than is typical in its investment category.

I also received and considered the history of portfolio manager changes for
each Fund, as this provided an important context for evaluating the
performance results.

Complex-Level Considerations

While this evaluation was conducted mainly at the individual fund level,
there are some issues relating to the reasonableness of fees that can
alternatively be considered across the whole fund complex:

I reviewed DeAM's profitability analysis for all DWS Funds, with a view
toward determining if the allocation procedures used were reasonable
and how profit levels compared with public data for other investment
managers.

I considered whether DeAM and affiliates receive any significant ancillary
or "fall-out" benefits that should be considered in interpreting the direct
profitability results. These would be situations where serving as the
investment manager of the Funds is beneficial to another part of the
Deutsche Bank organization.

I considered how aggregated DWS Fund expenses had varied over the
years, by asset class and in the context of trends in asset levels.

I reviewed the structure of the DeAM organization, trends in staffing
levels, and information on compensation of investment management and
other professionals compared with industry data.

Findings

Based on the process and analysis discussed above, which included
reviewing a wide range of information from management and external data
sources and considering among other factors the fees DeAM charges other
clients, the fees charged by other fund managers, DeAM's costs and profits
associated with managing the Funds, economies of scale, possible fall-out
benefits, and the nature and quality of services provided, in my opinion the
management fees charged the DWS Funds are reasonable.

Summary of Administrative Fee Evaluation
by Independent Fee Consultant

September 29, 2008

Pursuant to an Order entered into by Deutsche Asset Management (DeAM)
with the Attorney General of New York, I, Thomas H. Mack, have been
appointed the Independent Fee Consultant for the DWS Funds and have as
part of my duties evaluated the reasonableness of the proposed
management fees to be charged by DeAM to the DWS Funds, taking onto
account a proposal to pass through to the funds certain fund
accounting-related charges in connection with new regulatory requirements.
My evaluation considered the following:

•   While the proposal would alter the services to be provided under the
Administration Agreement, which I consider to be part of fund
management under the Order, it is my opinion that the change in
services is slight and that the scope of prospective services under the
combination of the Advisory and Administration Agreements continues
to be comparable with those typically provided to competitive funds
under their management agreements.

•   While the proposal would increase fund expenses, according to a pro
forma analysis performed by management, the prospective effect is less
than .01% for all but seven of the DeAM Funds' 438 active share
classes, and in all cases the effect is less than .03% and overall
expenses would remain reasonable in my opinion.

Based on the foregoing considerations, in my opinion the fees and expenses
for all of the DWS Funds will remain reasonable if the Directors adopt this
proposal.
