A group of investment professionals is responsible for the day-to-day
management of the Portfolio.

In the following interview, Lead Portfolio Manager Geoffrey Gibbs
discusses the market environment and the portfolio management
team's approach to managing Cash Management Fund Institutional
during its most recent fiscal year ended December 31, 2007.

The views expressed in the following discussion reflect those of the portfolio managers 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.

Q: Will you discuss the market environment for the fund during
the most recent fiscal year?

A:In the first quarter of 2007, increasing defaults by subprime
mortgage borrowers and losses on residential mortgage-back
securities sparked volatility in the financial markets as investors
wondered to what degree Wall Street and the banking community
would be affected by a retrenchment in this market. As we
entered the second half of the year, it became clear that several
financial firms would need to shed excess debt and sell assets in
order to cover significant losses. For much of August, buyers in
the credit markets had almost disappeared, replaced entirely by
sellers. At the short end of the yield curve, asset-backed
securities' yields spiked significantly, reflecting investors' credit
concerns, as did the London Interbank Offered Rate (LIBOR),
the industry standard for measuring one-year money market
rates.1,2,3 In response to this "credit crunch," as well as to fears
of an oncoming economic recession, the US Federal Reserve
Board (the Fed) cut the federal funds rate (the overnight rate
charged by banks when they borrow money from each other) a
total of one percentage point over three Federal Open Market
Committee (FOMC) meetings (from September through
December 2007). As a means of injecting further liquidity into the
global monetary system  as well as to persuade major banks to
resume their accustomed levels of interbank lending  the Fed
also set up a temporary "term auction facility."4 By the end of the
year, these measures seemed to restore a more typical flow of
funds and extension of credit, and LIBOR receded to a more
customary interest rate "spread" (or difference in yield) compared
with the federal funds rate.

As of December 31, 2007, the three-month LIBOR stood at
4.70%, compared with 5.73% on September 7, 2007
(during the height of the global credit crunch) and 5.36% on
December 31, 2006.

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

A:Given the difficult situation described above, and recognizing
that the credit crunch was not likely to be a short-term
phenomenon, our strategy for managing through the situation
was to avoid credit risk as much as possible. Therefore, especially
during the latter half of the year, we increased the fund's positions
in Treasury securities, agency securities and overnight liquidity
positions, and decreased holdings in asset-backed commercial
paper. During the summer we kept the fund's average maturity
short. But, confident that the Fed would need to cut rates, we
gradually extended maturity with very high-quality securities. With
this strategy, we were able to avoid problem credits and losses
stemming from the widespread credit issues in the market. Going
forward, we will continue to monitor investment markets,
economic data and Federal Reserve statements carefully.

Yields are historical, will fluctuate and do not guarantee future performance. The
7-day current yield refers to the income paid by the portfolio over a 7-day period
expressed as an annual percentage rate of the fund's shares outstanding. Please visit
our Web site at www.moneyfunds.deam-us.db.com for the product's most recent
month-end performance.

Q: What detracted from performance during the period?

A:The types of securities in which the fund was investing during
the second half of the year tended to have lower yields than
issues carrying more risk, such as structured investment vehicles
(SIVs), which we avoided. We opted for a more cautious stance,
which in the end cost the fund some yield but was a prudent
approach in preserving principal.

Q: Will you describe your investment philosophy?

A:We continue to insist on the highest credit quality within the
fund. We also plan to maintain conservative investment strategies
and standards. We 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 of the Fund, you incur two types of costs: ongoing
expenses and transaction costs. Ongoing expenses include management
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; 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
(July 1, 2007 to December 31, 2007).

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. If these transaction costs
had been included, your costs would have been higher.

Notes to Financial Statements

A. Significant Accounting Policies

Cash Management Fund Institutional (the ``Fund'') is a series of DWS
Institutional Funds (the ``Trust''), which is registered under the Investment
Company Act of 1940, as amended (the ``1940 Act''), as an open-end
management investment company organized as a Massachusetts business
trust. The Fund is one of several funds the Trust offers to investors.

The Fund seeks to achieve its investment objective by investing all of its
investable assets in the Cash Management Portfolio (the ``Portfolio''), an
open-end management investment company registered under the 1940
Act and advised by Deutsche Investment Management Americas Inc.
(``DIMA'' or the ``Advisor''). Details concerning the Portfolio's investment
objective and policies and the risk factors associated with the Portfolio's
investments are described in the Fund's Prospectus and Statement of
Additional Information.

At December 31, 2007, the Fund owned approximately 8% of the
Portfolio. The financial statements of the Portfolio, including the Investment
Portfolio, are contained elsewhere in this report and should be read in
conjunction with the Fund's financial statements.

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 its financial statements.

Security Valuation.The Fund determines the valuation of its investment in
the Portfolio by multiplying its proportionate ownership of the Portfolio by
the total value of the Portfolio's net assets.

The Portfolio's policies for determining the value of its net assets are
discussed in the Portfolio's financial statements which accompany this
report.

In September 2006, the Financial Accounting Standards Board ("FASB")
released Statement of Financial Accounting Standards No. 157, "Fair Value
Measurements" ("FAS 157"). FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair
value measurements. FAS 157 is effective for fiscal years beginning after
November 15, 2007. As of December 31, 2007, management does not
believe the adoption of FAS 157 will impact the amounts reported in the
financial statements, however, additional disclosures will be required
about the inputs used to develop the measurements of fair value and the
effect of certain of the measurements reported in the statement of
operations for a fiscal period.

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. Accordingly, the Fund paid no federal
income taxes and no federal income tax provision was required.

At December 31, 2007, the Fund had a net tax basis capital loss
carryforward of approximately $31,000 which may be applied against any
realized net taxable capital gains of each succeeding year until fully utilized
or until December 31, 2014, whichever occurs first. During the year ended
December 31, 2007, the Fund utilized $48,000 of its prior year capital loss
carryforward.

The Fund has reviewed the tax positions for each of the three open tax
years as of December 31, 2007 and has determined that no provision for
income tax is required in the Fund's financial statements. Each of the
Fund's federal tax returns for the prior three fiscal years remains subject
to examination by the Internal Revenue Service.

Distribution of Income.Net investment income of the Fund is declared as
a daily dividend and is distributed to shareholders monthly.

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

At December 31, 2007, the Fund's components of distributable earnings
(accumulated losses) on a tax basis were as follows:

|Undistributed ordinary income | $      76,207  
|----------------------------- | ---------------
|Capital loss carryforward     | $      (31,000)

In addition, during the year ended December 31, 2007, the tax character of
distributions paid to shareholders by the Fund is summarized as follows:

|                                   | Years Ended December 31,
|---------------------------------- | ------------------------
|                                   | 2007                    
|Distributions from ordinary income | $      121,385,570      

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.The Fund receives a daily allocation of the Portfolio's net
investment income and net realized gains and losses in proportion to its
investment in the Portfolio. Expenses directly attributed to a fund are
charged to that fund, while expenses which are attributable to the Trust
are allocated among the funds in the Trust on the basis of relative net
assets.

B. Fees and Transactions with Affiliates

Deutsche Investment Management Americas Inc. ("DIMA" or the
"Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG,
is the Advisor for the master portfolio.

For the period from January 1, 2007 through May 13, 2010, DIMA has
contractually agreed to waive a portion of their fees and/or reimburse
expenses of the Fund to the extent necessary to maintain total operating
expenses at 0.23% of the Fund's average daily net assets, including
expenses of the Portfolio (excluding certain expenses such as
extraordinary expenses, taxes, brokerage and interest expenses).

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 a fee ("Administration fee") of 0.10% of the Fund's average daily
net assets, computed and accrued daily and payable monthly.

For the year ended December 31, 2007, the Advisor waived a portion of its
Administration fee as follows:

|                                   | Total
Aggregated | Waived         | Unpaid at
December 31,

Effective Rate
|---------------------------------- | ---------------- | -------------- | --------------------------- | ---------------------
|Cash Management
Fund Institutional | $      2,380,220 | $      562,181 | $      326,534              | .08%                 

Service Provider Fees. DWS Scudder Investments Service Company
("DWS-SISC"), 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 DWS-SISC and DST
Systems, Inc. ("DST"), DWS-SISC has delegated certain transfer agent,
dividend-paying agent and shareholder service agent functions to DST.
DWS-SISC compensates DST out of the shareholder servicing fee it
receives from the Fund. For the year ended December 31, 2007, the
amount charged to the Fund by DWS-SISC aggregated $131,620, all of
which was waived.

In addition, DWS Scudder Distributors, Inc. ("DWS-SDI") also an affiliate
of the Advisor, provides information and administrative services for a fee
("Service Fee") to Institutional Class shareholders at an annual rate of up
to 0.25% of average daily net assets. DWS-SDI in turn has various
agreements with financial services firms that provide these services and
pays these fees based upon the assets of shareholder accounts the firm
services. For the year ended December 31, 2007, the Service Fee was as
follows:

|                                   | Total
Aggregated | Waived           | Annual
Effective Rate
|---------------------------------- | ---------------- | ---------------- | ---------------------
|Cash Management Fund Institutional | $      1,462,115 | $      1,462,115 | .00%                 

Typesetting and Filing Service Fees. Under an agreement with DIMA,
DIMA is compensated for providing typesetting and certain regulatory
filing services to the Fund. For the year ended December 31, 2007, the
amount charged to the Fund by DIMA included in the Statement of
Operations under "reports to shareholders" aggregated $19,085, of which
$10,663 is unpaid.

Trustees' Fees and Expenses.As compensation for his or her services,
each Independent Trustee receives an aggregate annual fee, plus a fee for
each meeting attended (plus reimbursement for reasonable out-of-pocket
expenses incurred in connection with his or her attendance at board and
committee meetings) from each fund in the Fund Complex for which he or
she serves. In addition, the Chairperson of the Board and the Chairperson
of each committee of the Board receive additional compensation for their
services. Payment of such fees and expenses is allocated among all such
funds described above in direct proportion to their relative net assets.

C. Concentration of Ownership

From time to time the Fund may have a concentration of several
shareholders holding a significant percentage of shares outstanding.
Investment activities of these shareholders could have a material impact
on the Fund.

At December 31, 2007, there was one shareholder who held
approximately 19% of the outstanding shares of the Fund.

the related statements of operations and of changes in net assets and the
financial highlights present fairly, in all material respects, the financial
position of Cash Management Fund Institutional (hereafter referred to as
the ``Fund'') at December 31, 2007, and the results of its operations, the
changes in its net assets and the financial highlights for each of the
periods indicated therein, in conformity with accounting principles
generally accepted in the United States of America. These financial
statements and financial highlights (hereafter referred to as ``financial
statements'') are the responsibility of the Fund's management. Our
responsibility is to express an opinion on these financial statements
based on our audits. We conducted our audits of these financial

Trustees and Officers

The following table presents certain information regarding the Board
Members and Officers of the Trust as of December 31, 2007. Each Board
Member's year of birth is set forth in parentheses after his or her name.
Unless otherwise noted, (i) each Board Member has engaged in the
principal occupation(s) noted in the table for at least the most recent five
years, although not necessarily in the same capacity, and (ii) the address
of each Independent Board Member is c/o Dawn-Marie Driscoll, PO Box
100176, Cape Coral, FL 33904. Except as otherwise noted below, the term
of office for each Board Member is until the election and qualification of a

Notes to Financial Statements

A. Significant Accounting Policies

Cash Management Portfolio (the ``Portfolio'') is registered under the
Investment Company Act of 1940, as amended (the ``1940 Act''), as an
open-end management investment company organized as a New York
business trust.

The Portfolio'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 Portfolio in the preparation of its financial statements.

Security Valuation.The Portfolio's 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.

Investments in open-end investment companies are valued at their net
asset value each business day.

In September 2006, the Financial Accounting Standards Board ("FASB")
released Statement of Financial Accounting Standards No. 157, "Fair Value
Measurements" ("FAS 157"). FAS 157 defines fair value, establishes a
framework for measuring fair value and expands disclosures about fair
value measurements. FAS 157 is effective for fiscal years beginning after
November 15, 2007. As of December 31, 2007, management does not
believe the adoption of FAS 157 will impact the amounts reported in the
financial statements, however, additional disclosures will be required
about the inputs used to develop the measurements of fair value and the
effect of certain of the measurements reported in the statement of
operations for a fiscal period.

Repurchase Agreements.The Portfolio may enter into repurchase
agreements with certain banks and broker/dealers whereby the Portfolio,
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 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 Portfolio has the right to sell the securities and
recover any resulting loss from the financial institution. If the financial
institution enters into bankruptcy, the Portfolio's claims on the collateral
may be subject to legal proceedings.

Federal Income Taxes.The Portfolio is considered a Partnership under the
Internal Revenue Code, as amended. Therefore, no federal income tax
provision is necessary.

The Portfolio has reviewed the tax positions for each of the three open tax
years as of December 31, 2007 and has determined that no provision for
income tax is required in the Portfolio's financial statements. Each of the
Portfolio's federal tax returns for the prior three fiscal years remains subject
to examination by the Internal Revenue Service.

Contingencies.In the normal course of business, the Portfolio may enter
into contracts with service providers that contain general indemnification
clauses. The Portfolio's maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against
the Portfolio that have not yet been made. However, based on experience,
the Portfolio 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. Distributions of income and
capital gains from investment companies are recorded on the ex-dividend
date. 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.

The Portfolio makes a daily allocation of its net investment income and
realized gains and losses from securities transactions to its investors in
proportion to their investment in the Portfolio.

B. Fees and Transactions with Affiliates

Deutsche Investment Management Americas Inc. ("DIMA" or the
"Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, is
the Advisor for the master portfolio.

Prior to May 14, 2007, the Portfolio paid the Advisor an annual advisory fee
of 0.15%, based on its average daily net assets, calculated daily and paid
monthly.

For the period from May 14, 2007 through July 31, 2007, under the
Advisor Agreement, the Portfolio pays the Advisor a monthly advisory fee
based on its average daily net assets, computed and accrued daily and
payable monthly, at the following annual rates:

|First $5.5 billion of the Fund's average daily net assets | .150%
|--------------------------------------------------------- | -----
|Next $5 billion of such net assets                        | .135%
|Over $10.5 billion of such net assets                     | .120%

Effective August 1, 2007, under the Advisor Agreement, the Portfolio pays
the Advisor a monthly advisory fee based on its average daily net assets,
computed and accrued daily and payable monthly, at the following annual
rates:

|First $3.0 billion of the Fund's average daily net assets | .150%
|--------------------------------------------------------- | -----
|Next $4.5 billion of such net assets                      | .133%
|Over $7.5 billion of such net assets                      | .120%

For the period from January 1, 2007 through May 13, 2007, the Advisor
had contractually agreed to waive a portion of its fees and/or reimburse
expenses of the Portfolio, to the extent necessary, to maintain total
operating expenses at 0.18% of its average daily net assets (excluding
certain expenses such as extraordinary expenses, taxes, brokerage,
interest, proxy and organizational and offering expenses).

For the period from May 14, 2007 through July 29, 2010, the Advisor has
contractually agreed to maintain total operating expenses at 0.15% of its
average daily net assets (excluding certain expenses such as extraordinary
expenses, taxes, brokerage and interest expenses). The amount of the
waiver and whether the Advisor and Administrator waive a portion of its
fees may vary at any time without notice to shareholders.

For the period from July 30, 2007 through September 25, 2007, the
Advisor has voluntarily agreed to maintain total operating expenses at
0.12% of its average daily net assets (excluding certain expenses such as
extraordinary expenses, taxes, brokerage and interest expenses).

For the period from September 26, 2007 through November 28, 2007, the
Advisor has voluntarily agreed to maintain total operating expenses at
0.14% of its average daily net assets (excluding certain expenses such as
extraordinary expenses, taxes, brokerage and interest expenses).

Effective November 29, 2007, the Advisor has voluntarily agreed to
maintain total operating expenses at 0.11% of its average daily net assets
(excluding certain expenses such as extraordinary expenses, taxes,
brokerage and interest expenses). The amount of the waiver and whether
the Advisor and Administrator waive a portion of its fee may vary at any
time without notice to shareholders.

Accordingly, for the year ended December 31, 2007 the total
management fee, management fee waived and effective management fee
were as follows:

|                          | Total
Aggregated  | Waived           | Annual
Effective Rate
|------------------------- | ----------------- | ---------------- | ---------------------
|Cash Management Portfolio | $      27,236,671 | $      6,007,663 | .10%                 

Administration Fee. Pursuant to an Administrative Services Agreement
with the Advisor, the Advisor provides most administrative services to the
Portfolio. For all services provided under the Administrative Services
Agreement, the Portfolio pays the Advisor an annual fee ("Administration
fee") of 0.03% of the Portfolio's average daily net assets, computed and
accrued daily and payable monthly. For the year ended December 31,
2007, the Advisor received an Administration fee of $6,287,793, of which
$911,650 is unpaid.

Trustees' Fees and Expenses.As compensation for his or her services,
each Independent Trustee receives an aggregate annual fee, plus a fee for
each meeting attended (plus reimbursement for reasonable out-of-pocket
expenses incurred in connection with his or her attendance at board and
committee meetings) from each fund in the Fund Complex for which he or
she serves. In addition, the Chairperson of the Board and the Chairperson
of each committee of the Board receive additional compensation for their
services. Payment of such fees and expenses is allocated among all such
funds described above in direct proportion to their relative net assets.

C. Fee Reductions

The Portfolio has entered into an arrangement with its custodian whereby
credits realized as a result of uninvested cash balances are used to reduce
a portion of the Portfolio's custodian expenses. During the year ended
December 31, 2007, the Portfolio's custodian fee was reduced by
$421,663 for custody credits earned.

D. Line of Credit

The Portfolio and other affiliated funds (the ``Participants'') share in a
$750 million revolving credit facility administered by JPMorgan Chase
Bank, N.A. 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 upon net assets, among each
of the Participants. Interest is calculated at the Federal Funds Rate plus
0.35 percent. The Portfolio may borrow up to a maximum of 5 percent of
its net assets under this agreement.

Report of Independent Registered
Public Accounting Firm

To the Trustees and Holders of Beneficial Interest of
Cash Management Portfolio:

In our opinion, the accompanying statement of assets and liabilities,
including the portfolio of investments, and the related statements of
operations and of changes in net assets and the financial highlights
presents fairly, in all material respects, the financial position of Cash
Management Portfolio (hereafter referred to as the ``Portfolio'') at
December 31, 2007, and the results of its operations, the changes in its
net assets and the financial highlights for each of the periods indicated
therein, in conformity with accounting principles generally accepted in the
United States of America. These financial statements and financial
highlights (hereafter referred to as ``financial statements'') are the
responsibility of the Portfolio's management. Our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these financial statements in accordance with the
standards of the Public Company Accounting Oversight Board (United
States). Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits, which included
confirmation of securities at December 31, 2007 by correspondence with
the custodian and brokers, provide a reasonable basis for our opinion.

Investment Management Agreement
Approval

The Cash Management Fund Institutional (the "Fund"), a series of
DWS Institutional Funds, invests all of its assets in Cash Management
Portfolio (the "Portfolio") in order to achieve its investment objectives.
The Portfolio's Trustees, who are also the Trustees of the Fund, approved
the continuation of the Portfolio's investment management agreement
with DIMA and Fund's investment management agreement with
DIMA (together, the "Investment Management Agreements") in
September 2007.

In terms of the process that the Trustees 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. In connection with reviewing the Investment Management
Agreements, the Trustees also review the terms of the Fund's
distribution agreement, administration agreement, transfer agency
agreement and other material service agreements.

In connection with the Board's 2007 contract review, the Board
formed a special committee to facilitate careful review of the funds'
contractual arrangements. After reviewing the Fund's arrangements,
that committee recommended that the Board vote to approve the
continuation of the Investment Management Agreements.

The Trustees regularly meet privately with their independent counsel
to discuss contract review and other matters. In addition, the
Trustees were also advised by two consultants, including the Fund's
independent fee consultant, in the course of their 2007 review of the
Fund's contractual arrangements. In particular, the Trustees considered
the report prepared by the independent fee consultant in connection
with their deliberations.

The Trustees believe that a long-term relationship with a capable,
conscientious advisor is in the best interest of shareholders. As you may
know, DIMA is part of Deutsche Bank, a major global banking institution
that is engaged in a wide range of financial services. The Trustees believe
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.

Shareholders may focus primarily on fund performance and fees, but the
Portfolio's Trustees consider 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.

In determining to approve the continuation of the Investment
Management Agreements, the Board considered all factors that it
believes relevant to the interests of Fund shareholders, including:

The investment management fee schedule for the Portfolio, including
(i) comparative information provided by Lipper regarding investment
management fee rates paid to other investment advisors by similar
funds and (ii) fee rates paid to DIMA by similar funds and
institutional accounts advised by DIMA (if any).With respect to
management fees paid to other investment advisors by similar funds,
the Trustees noted that the contractual fee rates paid by the Fund
were expected to be higher than the median (4th quartile) of the
applicable Lipper peer group (based on Lipper data provided as of
December 31, 2006). The Board noted that DIMA agreed to accept the
introduction of new breakpoints in the Portfolio's investment
management fee schedule during 2007. The Board noted that although
shareholders of the Fund indirectly bear the Portfolio's management
fee, the Fund does not charge an additional investment management
fee. Taking into account the foregoing, the Board concluded that the
fee schedule in effect for the Portfolio represents reasonable
compensation in light of the nature, extent and quality of the
investment services being provided to the Portfolio.

The extent to which economies of scale would be realized as the
Portfolio grows.In this regard, the Board noted that the Fund's
investment management fee schedule includes fee breakpoints.
The Board concluded that the Portfolio's fee schedule represents an
appropriate sharing between shareholders and DIMA of such
economies of scale as may exist in the management of the Portfolio
at current asset levels.

The total operating expenses of the Fund.In this regard, the Board
noted that the total (net) operating expenses of the Fund (Institutional
Class Shares) are expected to be higher than the median (3rd quartile)
of the applicable Lipper expense universe (based on Lipper data
provided as of December 31, 2006). The Board considered the
expenses of this class to be representative for purposes of evaluating
other classes of shares. 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
limitation agreed to by DIMA helped to ensure that the Fund's total
(net) operating expenses would be competitive relative to the
applicable Lipper universe.

The investment performance of the Fund and DIMA, both absolute
and relative to various benchmarks and industry peer groups.The
Board noted that for each of the one-, three- and five-year periods
ended December 31, 2006, the Fund's performance was in the
2nd quartile of the applicable iMoneyNet universe. The Board also
observed that the Fund has outperformed its benchmark in each of the
one-, three- and five-year periods ended December 31, 2006. The
Board recognized that DIMA has made significant changes in its
investment personnel and processes in recent years in an effort to
improve long-term performance.

The nature, extent and quality of the advisory services provided by
DIMA.The Board considered extensive information regarding DIMA,
including DIMA's personnel (including particularly those personnel with
responsibilities for providing services to the Portfolio), resources,
policies and investment processes. The Board also considered the
terms of the Investment Management Agreements, including the
scope of services provided under the agreement. In this regard, the
Board concluded that the quality and range of services provided by
DIMA have benefited and should continue to benefit the Fund and its
shareholders.

The costs of the services to, and profits realized by, DIMA and its
affiliates from their relationships with the Portfolio and the Fund.The
Board reviewed information concerning the costs incurred and profits
realized by DIMA during 2006 from providing investment management
services to the Fund (and, separately, to the entire DWS Scudder fund
complex), and reviewed with DIMA the cost allocation methodology
used to determine DIMA's profitability. In analyzing DIMA's costs and
profits, the Board also reviewed the fees paid to and services provided
by DIMA and its affiliates with respect to administrative services,
transfer agent services, shareholder servicing and distribution
(including fees paid pursuant to 12b-1 plans), as well as information
regarding other possible benefits derived by DIMA and its affiliates as
a result of DIMA's relationship with the Portfolio and the Fund. As
part of this review, the Board considered information provided by an
independent accounting firm engaged to review DIMA's cost allocation
methodology and calculations. The Board concluded that the Portfolio's
investment management fee schedule represented reasonable
compensation in light of the costs incurred by DIMA and its affiliates
in providing services to the Portfolio and the Fund. 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 Scudder
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.

The practices of DIMA regarding the selection and compensation of
brokers and dealers executing portfolio transactions for the Portfolio.The Board considered that a portion of the Portfolio's brokerage may
be allocated to affiliates of DIMA, subject to compliance with
applicable SEC rules. The Board also considered that, subject to
ongoing review by the Board, a limited portion of the Portfolio's
brokerage may be allocated to brokers who acquire (and provide to
DIMA and its affiliates) research services from third parties that are
generally useful to DIMA and its affiliates in managing client portfolios.
The Board indicated that it would continue to monitor the allocation of
the Portfolio's brokerage to ensure that the principle of "best price and
execution" remains paramount in the portfolio trading process.

DIMA's commitment to and record of compliance, including its
written compliance policies and procedures.In this regard, the Board
considered DIMA's commitment to indemnify the Fund against any
costs and liabilities related to lawsuits or regulatory actions arising
from allegations regarding market timing, revenue sharing, fund
valuation or other subjects arising from or relating to pending
regulatory inquiries. The Board also 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.

Deutsche Bank's commitment to its US mutual fund business.The
Board considered recent and ongoing efforts by Deutsche Bank to
restructure its US mutual fund business to improve efficiency and
competitiveness and to reduce compliance and operational risk. The
Board considered assurances received from Deutsche Bank that it
would commit the resources necessary to maintain high-quality
services to the Portfolio and its shareholders. The Board also
considered Deutsche Bank's strategic plans for its US mutual fund
business, the potential benefits to Fund shareholders and Deutsche
Bank's management of one of Europe's most successful fund groups.

Based on all of the foregoing, the Board determined to continue the
Investment Management Agreements, and concluded that the
continuation of such agreements was in the best interests of the Fund's
shareholders.

In reaching this conclusion the Board did not give particular weight to any
single factor identified above. The Board considered these factors over the
course of numerous meetings, many 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 current agreements.

Summary of Management Fee Evaluation
by Independent Fee Consultant

October 26, 2007

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 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 2007, including my qualifications, the evaluation process for
each of the DWS Scudder Funds, consideration of certain complex-level
factors, and my conclusions.

Qualifications

For more than 30 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 several 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 Scudder Fund

My work focused primarily on evaluating, fund-by-fund, the fees charged
to each of the 136 Fund portfolios in the DWS Scudder 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 Scudder Fund. These similar
products included the other DWS Scudder 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 Scudder 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 Scudder 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 Scudder 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 Scudder
Funds are reasonable.
