**Portfolio Management Review**

In the following interview, the portfolio management team discusses the market environment and the team's approach to managing ICT-Treasury Portfolio during the fund's most recent semiannual period ended September 30, 2008.

*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 the fund during the most recent semiannual period?**

**A:** Over the past six months we continued to witness unprecedented events in 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 eventually brought down several financial firms, including Bear Stearns and Lehman Brothers, and transformed Wall Street. September in particular was            an exceptionally traumatic month for the financial industry as severe losses and the general liquidity squeeze forced major financial companies such as Merrill Lynch, AIG, Washington Mutual and Wachovia to seek a rescue throughout a government bailout or a merger. The loss of market liquidity forced the US Federal Reserve Board (the Fed) and other central banks to make significant efforts to boost liquidity by creating expansive lending facilities. Among other unprecedented            actions, the US government decided to back Fannie Mae and Freddie Mac explicitly, inject $700 billion into the banking system through the Troubled Asset Relief Program (TARP) program and offer a stimulus package to US consumers. (In October 2008, a second stimulus package was under consideration because of continued economic worries.)

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 as investors prized safety over all other considerations, including yield.1 This unprecedented flight to quality pushed the yield of the three-month Treasury bill to almost zero on September 17, 2008, under the extreme demand pressure.

In response to the freeze-up in money market liquidity, the US government created new lending facilities for commercial paper and asset-backed commercial paper, and by late October was on the verge of launching a general money market lending facility. The government also issued new short-term Treasury instruments to meet strong investor demand. By October, these new government programs seemed to be restoring some measure of            liquidity in the money markets, though we believe it will take several months for normalcy to be restored.

As of September 30, 2008, the three-month LIBOR, an industry standard for measuring three-month taxable money market rates, stood at 4.05%, compared with 2.69% as of March 31, 2008.2

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

**A:** As stated, we have witnessed unprecedented demand for Treasury securities over the past six months, especially during September. Through the first four months of the period, as Treasury bills became more expensive, we maintained a significant allocation in overnight Treasury repurchase agreements, where we could capture reasonable yield. We also kept the fund's weighted average maturity short in            order to exercise caution during a turbulent period.

As the government's lending facilities and new guarantees for financial instruments began to ease the credit freeze-up for prime (non-Treasury) money market funds, thereby helping to improve market conditions somewhat, and as new short-term Treasury issues lessened supply pressures, we increased the fund's allocation to Treasury bills in order to boost yield. By the close of the period, the fund's weighted average maturity had            lengthened somewhat because of the fund's increased allocation to one, three- and six-month Treasury bills.

**Q: What detracted from performance during the period?**

**A:** The types of securities that we were investing in 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 it represented a prudent approach to 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 our conservative investment strategies and standards, applying a careful approach to investing while seeking competitive yield for our shareholders.

**Information About Your Portfolio'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 Portfolio 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 Portfolio 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 Portfolio's Institutional Shares 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 (April 1, 2008 to September 30, 2008).

The tables illustrate the Portfolio's expenses in two ways:

•**Actual Portfolio Return.** This helps you estimate the actual dollar amount of ongoing expenses (but not transaction costs) paid on a $1,000 investment in the Portfolio using the Portfolio'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% Portfolio Return.** This helps you to compare your Portfolio's ongoing expenses (but not transaction costs) with those of other mutual funds using the Portfolio's actual expense ratio and a hypothetical rate of return of 5% per year before expenses. Examples using a 5% hypothetical portfolio 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**

**1. Significant Accounting Policies**

Investors Cash Trust (the "Trust") is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end, diversified investment management company organized as a Massachusetts business trust.

The Treasury Portfolio ("the Portfolio") offers multiple classes of shares that include: Institutional Shares, Premier Money Market Shares, Investment Class and DWS U.S. Treasury Money Fund Class S. Certain detailed financial information for the Premier Money Market Shares, Investment Class and DWS U.S. Treasury Money Fund Class S is provided separately and is available upon request.

Investment income, realized gains and losses, and certain portfolio-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 Trust have equal rights with respect to voting subject to class-specific arrangements.

The Trust'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 Trust in the preparation of its 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. Investments in open-end investment companies are valued at their net asset value each business day.

The Portfolio adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("FAS 157"), effective at the beginning of the Portfolio's fiscal year. FAS 157 establishes a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and requires additional disclosure about the classification of fair value            measurements.

Various inputs are used in determining the value of the Portfolio'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, credit risk, etc.). Level 3 includes significant unobservable            inputs (including the Portfolio'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. Most 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.

**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 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 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'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 March 31, 2008, the Portfolio had a net tax basis capital loss carryforward of approximately $33,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until March 31, 2013 ($10,300), March 31, 2014 ($20,400), March 31, 2015 ($2,300), the respective expiration dates, whichever occurs first.

The Portfolio has reviewed the tax positions for the three open tax years as of March 31, 2008 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 remain subject to examination by the Internal Revenue Service.

**Distribution of Income and Gains.** Net investment income of the Portfolio is declared as a daily dividend and is distributed to shareholders monthly. The Portfolio may take into account capital gains and losses in its daily dividend declarations. The Portfolio 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 Portfolio.

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 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. 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.

**2. Related Parties**

**Management Agreement.** Under the Amended and Restated 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 Portfolio in accordance with its 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 Portfolio.

Prior to May 1, 2008, in addition to portfolio management services, the Advisor provided certain administrative services in accordance with the Investment Management Agreement. For the period from April 1, 2008 through April 30, 2008, the Portfolio paid a monthly management fee of 1/12 of the annual rate of 0.15% of average daily net assets.

Effective May 1, 2008, under the Amended and Restated Investment Management Agreement with the Advisor, the Portfolio pays a monthly management fee of 0.05% of the Portfolio's average daily net assets.

For the period from April 1, 2008 through the expiration dates noted below, the Advisor has contractually agreed to waive all or a portion of its management fee and reimburse or pay certain operating expenses of the Portfolio (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) to the extent necessary to maintain the operating expenses of each class as follows:
|                                 |   | **Expiration Date** |
|--------------------------------------|--------|---------------------|
| Institutional Shares                 | .25%   | 9/14/2010           |
| Premier Money Market Shares          | .98%   | 5/20/2010           |
| Investment Class                     | .67%   | 9/14/2010           |
| DWS U.S. Treasury Money Fund Class S | .65%   | 5/18/2010           |

Accordingly, for the six months ended September 30, 2008, the fee pursuant to the management agreements was equivalent to an annualized effective rate of 0.07% of the Portfolio's average daily net assets.

**Administration Fee.** Effective May 1, 2008, the Portfolio entered into an Administrative Services Agreement with DIMA, pursuant to which DIMA 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 0.10% of the Portfolio's average daily net assets, computed and            accrued daily and payable monthly. For the period from May 1, 2008 through September 30, 2008, the Advisor received an Administration Fee of $1,304,453, of which $307,310 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 Portfolio. Pursuant to a sub-transfer agency agreement between 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 Portfolio. For the six months ended September 30, 2008, the amounts charged to the Portfolio by DISC were as follows:
| **Services to Shareholders**         | **Total Aggregated** | **Waived**  | **Unpaid at September 30, 2008** |

**Typesetting and Filing Service Fees.** Under an agreement with DIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Portfolio. For the six months ended September 30, 2008, the amount charged to the Portfolio by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $28,232, of which $6,348 is unpaid.

**Trustees' Fees and Expenses.** The Portfolio paid each Trustee not affiliated with the Advisor retainer fees plus specified amounts for various committee services and for the Board Chairperson and Vice Chairperson.

In connection with the board consolidation on April 1, 2008, of the two DWS Funds Boards of Trustees, certain Independent Board Members retired prior to their normal retirement date, and received a one-time retirement benefit. DIMA has agreed to reimburse the Funds for the cost of this benefit. During the period ended September 30, 2008, the Portfolio paid its allocated portion of the retirement benefit of $121,800 to the            non-continuing Independent Board Members, and the Portfolio was reimbursed by DIMA for this payment.

**3. Fee Reductions**

The Portfolio has entered into an arrangement with its custodian and transfer agent whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Portfolio's custodian expenses. During the six months ended September 30, 2008 the Portfolio's custodian fee was reduced by $30,305 and $5,505, respectively, for custody and transfer agent credits earned.

**4. Line of Credit**

The Portfolio and other affiliated funds (the "Participants") share in a $490 million revolving credit facility provided by a syndication of banks. The Portfolio 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 Trust may borrow up to a maximum of 33 percent of its net assets under the agreement.

**7. Participation in the Treasury's Temporary Guarantee Program**

The U.S. Department of the Treasury (the "Treasury") has established a Temporary Guarantee Program for Money Market Funds (the "Program"). The Portfolio has been accepted in the Program.

The Program is designed to protect the value of accounts in the Portfolio 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 Portfolio's for an account opened after            September 19, 2008 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 Portfolio's net asset value falls below $0.995 and the Portfolio 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. As of the date of this report, ESF assets are approximately $50 billion. The Treasury and the Secretary of the Treasury have the authority to use assets from the ESF for purposes other than those of the Program.

The Portfolio will bear the expenses of participating in the Program. For the initial three months of the Program, the Portfolio will pay 0.01% of the product of (i) the number of shares outstanding as of September 19, 2008 and (ii) $1.00, as required under the Program. The Program is set to terminate on December 18, 2008, 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 December 18, 2008, the Portfolio would need to pay an additional fee and there can be no assurances that the Portfolio will continue to participate.

Neither the Portfolio nor Deutsche Investment Management Americas Inc., the Portfolio'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 market indices and 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 gross performance (Premier Money Market Shares) was in the 3rd quartile, 2nd quartile and 2nd quartile, respectively, 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 class: Investment Class shares (3rd quartile) and lower than the median of the applicable Lipper expense universe for the following share classes: Institutional Shares (1st quartile), Premier Money Market Shares (1st quartile) and DWS U.S. Treasury Money Fund Class S shares (1st 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 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.
