Performance Summary March 31, 2009

Classes A, B, C, R and Institutional Class

All performance shown is historical, assumes reinvestment of all dividend and capital gain distributions, and does not guarantee future results. Investment return and principal value fluctuate with changing market conditions so that, when redeemed, shares may be worth more or less than their original cost. Current performance may be lower or higher than the performance quoted. Please visit www.dws-investments.com for the Fund's most recent month-end performance.

The maximum sales charge for Class A shares is 5.75%. For Class B shares, the maximum contingent deferred sales charge (CDSC) is 4% within the first year after purchase, declining to 0% after six years. Class C shares have no front-end sales charge but redemptions within one year of purchase may be subject to a CDSC of 1%. Unadjusted returns do not reflect sales charges and would have been lower if they had. Class R and Institutional Class shares are not subject to sales charges.

The total annual fund operating expense ratios, gross of any fee waivers or expense reimbursements, as stated in the fee table of the prospectus dated February 1, 2009 are 1.07%, 2.02%, 1.89%, 1.41% and 0.73% for Class A, Class B, Class C, Class R and Institutional Class shares, respectively. Please see the Information About Your Fund's Expenses, the Financial Highlights and Notes to the Financial Statements (Note C, Related Parties) sections of this report for gross and net expense related disclosure for the period ended March 31, 2009.

To discourage short-term trading, the Fund imposes a 2% redemption fee on shareholders redeeming shares held less than 15 days, which has the effect of lowering total return.

Returns and rankings during all periods shown for Class A, Class B, Class R and Institutional Class shares and for the 5-year and 10-year periods shown for Class C shares reflect a fee waiver and/or expense reimbursement. Without this waiver/reimbursement, returns and rankings would have been lower.

Performance figures do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Returns and rankings may differ by share class.

Returns shown for Class A, B and C shares for the period prior to their inception on June 25, 2001 and for Class R shares for the period prior to its inception on November 3, 2003 are derived from the historical performance of the Fund's original share class (Class AARP) of DWS Capital Growth Fund during such periods and have been adjusted to reflect the higher total annual operating expenses of each specific class. Any difference in expenses will affect performance. Class AARP shares converted into Class S shares on July 14, 2006.

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, distribution and service (12b-1) fees and other Fund expenses. Examples of transaction costs include sales charges (loads), redemption fees and 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, Class A, B, S, R and Institutional Class shares limited these expenses; had they 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 (October 1, 2008 to March 31, 2009).

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

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

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

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

Portfolio Management Review

In the following interview, the portfolio management team discusses DWS Capital Growth Fund's performance, strategy and the market environment during the six-month period ended March 31, 2009.

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

Q: How would you describe the economic and market environment over the last six months?

A: In the last annual report for this fund, published six months ago, we described the preceding year as a time of economic uncertainty and turmoil in capital markets. In the ensuing months, there was pronounced deterioration in the economy and financial markets, not only in the US but throughout the world. In December 2008, the National Bureau of Economic Research officially declared that the US economy had fallen into a recession that began in December 2007. With the economy and financial markets closely interrelated, the limited availability of credit and a lack of investor confidence hit asset prices, and the resulting loss of wealth contributed further to an economic slowdown. There was a pronounced decline in the equity market and in essentially all asset classes that carry risk in the final months of 2008. Although the equity markets remained weak into early 2009, there were nascent signs of improvement in the economy and the credit markets. Bonds began to recover in the first quarter of 2009, and the US equity market rallied impressively in March.

Despite the strength in March, most equity investments posted negative returns for the six months ended March 31, 2009. The Russell 3000^® Index, which is generally regarded as a good indicator of the broad stock market, returned -31.12% for the period.¹ Within the large-cap arena (large-cap companies have a marked capitalization of over $5 billion), which is the major focus of this fund, growth stocks performed better than value stocks: the Russell 1000^® Growth Index had a return of -25.97%, while the Russell 1000^® Value Index returned -35.22%.² All of the 10 sectors in the Russell 1000 Growth Index had negative returns; the weakest sector was financials, while the strongest was health care.

Q: How did the fund perform during this period?

A: DWS Capital Growth Fund's Class A shares produced a total return of -26.93% for the six months ended March 31, 2009. (Returns are unadjusted for sales charges. If sales charges had been included, returns would have been lower. Past performance is no guarantee of future results. Please see pages 4 through 9 for the performance of other share classes and more complete performance information.) The Russell 1000 Growth Index returned -25.97% and the Standard & Poor's 500^® (S&P 500) Index returned -30.54% for the six-month period.³ The average return of the fund's peer group of Lipper Large-Cap Growth Funds was -26.00%.⁴

Q: How is the fund managed?

A: The fund seeks to provide long-term growth of capital. We normally invest at least 65% of total assets in equities, mainly common stocks of US companies. Although the fund can invest in companies of any size, the focus is generally on established companies that are similar in size to the companies in the S&P 500 Index or the Russell 1000 Growth Index (as of December 31, 2008, the S&P 500 Index and the Russell 1000 Growth Index had median market capitalizations of $6.4 billion and $3.3 billion, respectively). The fund may also invest in other types of equity securities, such as preferred stocks or convertible securities.

In choosing stocks, we begin by utilizing a proprietary quantitative model to rank stocks based on a number of factors including valuation and profitability. We also apply fundamental techniques to identify companies that display above-average earnings growth compared to other companies and that have strong product lines, effective management and leadership positions within core markets. We will normally sell a stock when we believe its potential risks have increased, its price is unlikely to go higher, its fundamental factors have changed, other investments offer better opportunities or in the course of adjusting the fund's emphasis on a given industry.

Q: Which of your investment choices had the greatest impact on performance for the period?

A: On the whole, sector allocation contributed to performance relative to the Russell 1000 Growth Index, while stock selection detracted. Performance benefited from an overweight and stock selection in the materials sector.⁵ A significant negative was stock selection in the energy sector, as well as an overweight in that sector. Positions in the materials sector that contributed to relative performance included Praxair, Inc., an industrial gas supplier, and Barrick Gold Corp., a Canadian gold mining company.

Also positive was a position in Gilead Sciences, Inc., a biopharmaceutical company that is in the process of strengthening its industry position through an acquisition.

In the energy sector, performance was hurt by a position in Devon Energy Corp.*, an independent energy company engaged in oil and gas exploration, development and production; since Devon is not included in the Russell 1000 Growth Index, this position was a significant detractor from performance relative to the benchmark. Also negative for relative performance was an underweight in ExxonMobil Corp., which performed better than many energy companies.

Other detractors included insurer Aflac, Inc.* and service provider State Street Corp.*, both in the financials sector. Additions to the portfolio in the financials sector included CME Group, Inc., a leader in electronic trading, and investment manager T. Rowe Price Group, Inc., both of which contributed to performance near the end of the period.

Q: How is the fund currently positioned?

A: Although the market's rally in March was encouraging, we do not believe we have reached the end of the economic and market downturn, as we believe that many companies will continue to report disappointing earnings. As we look to make our way out of this tumultuous period, we continue to search for indications that the economy is stabilizing and to identify likely sources of market leadership.

We view political actions as an increasing factor in our decision- making process. After months of having a significant overweight to health care, a sector that generally tends to be insulated somewhat from economic cycles, we have reduced the fund's position in the sector because of concerns about the impact of government policy on the health care industry.

Although we continue to maintain a defensive posture, we have added some economically sensitive names, as we believe that government stimulus will likely help drive demand in the second half of the year. We have increased the position in technology, bringing the portfolio up to a slight underweight after having a significant underweight position. We added to the overweight in the materials sector by increasing the position in Monsanto Co. and establishing a position in Celanese Corp., and we are maintaining an overweight in energy.

The fund's largest underweight positions are in the consumer staples and consumer discretionary sectors. We believe that, unlike periods of recovery from past recessions, consumers will be hesitant to spend for an extended period of time. We continue to have an overweight position in telecommunications, while we increased the fund's underweight in industrials.

We believe our risk-managed, high-quality approach to growth investing can provide investors with attractive risk-adjusted returns over longer periods of time.

Fair Value Measurements

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

Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

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

Valuation Inputs	Investments in Securities
Level 1	$ 1,719,560,398
Level 2	53,291,148

Notes to Financial Statements (Unaudited)

A. Significant Accounting Policies

DWS Capital Growth Fund (the "Fund") is a diversified series of DWS Investment Trust (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 offers multiple classes of shares which provide investors with different purchase options. Class A shares are offered to investors subject to an initial sales charge. Class B shares are offered to investors without an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions. Class B shares automatically convert to Class A shares six years after issuance. Class C shares are offered to investors without an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. Class C shares do not automatically convert into another class. Institutional Class shares are offered to limited groups of investors, are not subject to initial or contingent deferred sales charges and have lower ongoing expenses than other classes. Class R shares are only available to participants in certain retirement plans and are offered to investors without an initial sales charge or contingent deferred sales charge. Class S shares are not subject to initial or contingent deferred sales charges and are generally not available to new investors except under certain circumstances.

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

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

Security Valuation. Investments are stated at value determined as of the close of regular trading on the New York Stock Exchange on each day the exchange is open for trading. Equity securities are valued at the most recent sale price or official closing price reported on the exchange (US or foreign) or over-the-counter market on which the security is traded most extensively. Securities for which no sales are reported are valued at the calculated mean between the most recent bid and asked quotations on the relevant market or, if a mean cannot be determined, at the most recent bid quotation.

Money market instruments purchased with an original or remaining maturity of sixty days or less, maturing at par, are valued at amortized cost. Investments in open-end investment companies and Cash Management QP Trust are valued at their net asset value each business day.

Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Trustees. In accordance with the Fund's valuation procedures, factors used in determining value may include, but are not limited to, the type of the security, the size of the holding, the initial cost of the security, the existence of any contractual restrictions on the security's disposition, the price and extent of public trading in similar securities of the issuer or of comparable companies, quotations or evaluated prices from broker-dealers and/or pricing services, information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities), an analysis of the company's financial statements, an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold and with respect to debt securities, the maturity, coupon, creditworthiness, currency denomination, and the movement of the market in which the security is normally traded. The value determined under these procedures may differ from published values for the same securities.

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

New Accounting Pronouncement. In April 2009, FASB issued FASB Staff Position No. 157-4, "Determining Fair Value When the Volume and Level of Activity for the Asset or Liability Have Significantly Decreased and Identifying Transactions That Are Not Orderly" ("FSP 157-4"). FSP 157-4 provides additional guidance for estimating fair value in accordance with FAS 157, when the volume and level of activity for the asset or liability have significantly decreased as well as guidance on identifying circumstances that indicate a transaction is not orderly. FSP 157-4 is effective for fiscal years and interim periods ending after June 15, 2009. Management is currently reviewing the enhanced disclosure requirements for the adoption of FSP 157-4.

Foreign Currency Translations. The books and records of the Fund are maintained in US dollars. Investment securities and other assets and liabilities denominated in a foreign currency are translated into US dollars at the prevailing exchange rates at period end. Purchases and sales of investment securities, income and expenses are translated into US dollars at the prevailing exchange rates on the respective dates of the transactions.

Net realized and unrealized gains and losses on foreign currency transactions represent net gains and losses between trade and settlement dates on securities transactions, the disposition of forward foreign currency exchange contracts and foreign currencies, and the difference between the amount of net investment income accrued and the US dollar amount actually received. That portion of both realized and unrealized gains and losses on investments that results from fluctuations in foreign currency exchange rates is not separately disclosed but is included with net realized and unrealized gain/appreciation and loss/depreciation on investments.

Securities Lending. The Fund may lend securities to financial institutions. The Fund retains beneficial ownership of the securities it has loaned and continues to receive interest and dividends paid by the issuer of securities and to participate in any changes in their market value. The Fund requires the borrowers of the securities to maintain collateral with the Fund consisting of liquid, unencumbered assets having a value at least equal to the value of the securities loaned. When the collateral falls below specified amounts, the lending agents will use their best efforts to obtain additional collateral on the next business day to meet required amounts under the security lending agreement. The Fund may invest the cash collateral into a joint trading account in an affiliated money market fund pursuant to Exemptive Orders issued by the SEC. The Fund receives compensation for lending its securities either in the form of fees or by earning interest on invested cash collateral net of borrower rebates and fees paid to a lending agent. Either the Fund or the borrower may terminate the loan. There may be risks of delay and costs in recovery of securities or even loss of rights in the collateral should the borrower of the securities fail financially. The Fund is also subject to all investment risks associated with the reinvestment of any cash collateral received, including, but not limited to, interest rate, credit and liquidity risk associated with such investments.

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

At September 30, 2008, the Fund had a net tax basis capital loss carryforward of approximately $617,385,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until September 30, 2009 ($95,111,000), September 30, 2010 ($46,239,000), September 30, 2011 ($305,729,000) and September 30, 2012 ($170,306,000), the expiration dates, whichever occurs first, subject to certain limitations under Sections 382-384 of the Internal Revenue Code.

The Fund has reviewed the tax positions for the open tax years as of September 30, 2008 and has determined that no provision for income tax is required in the Fund's financial statements. The Fund's federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Distribution of Income and Gains. Net investment income of the Fund, if any, is declared and distributed to shareholders annually. Net realized gains from investment transactions, in excess of available capital loss carryforwards, would be taxable to the Fund if not distributed, and, therefore, will be distributed to shareholders at least annually.

The timing and characterization of certain income and capital gains distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to certain securities sold at a loss. As a result, net investment income (loss) and net realized gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. Accordingly, the Fund may periodically make reclassifications among certain of its capital accounts without impacting the net asset value of the Fund.

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

Redemption Fees. The Fund imposes a redemption fee of 2% of the total redemption amount on the Fund shares redeemed or exchanged within 15 days of buying them, either by purchase or exchange. This fee is assessed and retained by the Fund for the benefit of the remaining shareholders. The redemption fee is accounted for as an addition to paid-in capital.

Expenses. Expenses of the Trust arising in connection with a specific fund are allocated to that fund. Other Trust expenses which cannot be directly attributed to a fund are apportioned among the funds in the Trust.

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

Other. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment security transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date net of foreign withholding taxes. Realized gains and losses from investment transactions are recorded on an identified cost basis.

B. Purchases and Sales of Securities

During the six months ended March 31, 2009, purchases and sales of investment securities (excluding short-term investments) aggregated $750,468,126 and $694,443,644, respectively.

C. Related Parties

Management Agreement. Under the Investment Management Agreement with Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the Advisor directs the investments of the Fund in accordance with 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 Fund.

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

First $250 million of the Fund's average daily net assets	.495%
Next $750 million of such net assets	.465%
Next $1.5 billion of such net assets	.445%
Next $2.5 billion of such net assets	.425%
Next $2.5 billion of such net assets	.395%
Next $2.5 billion of such net assets	.375%
Next $2.5 billion of such net assets	.355%
Over $12.5 billion of such net assets	.335%

Accordingly, for the six months ended March 31, 2009, the fee pursuant to the management agreement was equivalent to an annualized effective rate of 0.46% of the Fund's average daily net assets.

For the period from October 1, 2008 through November 30, 2008, the Advisor had contractually agreed to waive all or a portion of its management fee and reimburse or pay certain operating expenses of the Fund (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:

Class A	1.06%
Class B	2.01%
Class C	1.99%
Class R	1.45%
Class S	.80%
Institutional Class	.73%

Administration Fee. Pursuant to an Administrative Services Agreement, DIMA provides most administrative services to the Fund.

For the six months ended March 31, 2009, the Advisor received an Administration Fee of $700,725, of which $105,016 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 of the Fund. 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 Fund. For the six months ended March 31, 2009, the amounts charged to the Fund by DISC were as follows:

Services to Shareholders	Total Aggregated	Waived	Unpaid at March 31, 2009

Institutional Class	43,605	4,956	23,688
	$ 1,347,905	$ 89,595	$ 675,135

Distribution and Service Fees. Under the Fund's Class B, C and R 12b-1 Plans, DWS Investments Distributors, Inc. ("DIDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.75%, 0.75% and 0.25% of average daily net assets of each of Class B, C and R shares, respectively. In accordance with the Fund's Underwriting and Distribution Service Agreement, DIDI enters into related selling group agreements with various firms at various rates for sales of Class B, C and R shares. For the period from October 1, 2008 through January 31, 2009, DIDI had voluntarily agreed to waive the 0.75% 12b-1 distribution fee for Class B shares only. For the six months ended March 31, 2009, the Distribution Fee was as follows:

Distribution Fee	Total Aggregated	Waived	Unpaid at March 31, 2009
Class B	$ 64,424	$ 46,003	$ —
Class C	82,541	—	13,795
Class R	36,202	—	6,544
	$ 183,167	$ 46,003	$ 20,339

In addition, DIDI provides information and administrative services for a fee ("Service Fee") to Class A, B, C and R shareholders at an annual rate of up to 0.25% of average daily net assets for each such class. DIDI 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 firms service. For the six months ended March 31, 2009, the Service Fee was as follows:

Service Fee	Total Aggregated	Waived	Unpaid at March 31, 2009	Annualized Effective Rate
Class A	$ 583,398	$ —	$ 83,495	.23%
Class B	20,776	—	1,373	.24%
Class C	27,091	—	3,742	.25%
Class R	36,087	1,881	6,234	.24%
	$ 667,352	$ 1,881	$ 94,844

Underwriting Agreement and Contingent Deferred Sales Charge. DIDI is the principal underwriter for the Fund. Underwriting commissions paid in connection with the distribution of Class A shares for the six months ended March 31, 2009, aggregated $23,007.

In addition, DIDI receives any contingent deferred sales charge ("CDSC") from Class B share redemptions occurring within six years of purchase and Class C share redemptions occurring within one year of purchase. There is no such charge upon redemption of any share appreciation or reinvested dividends. The CDSC is based on declining rates ranging from 4% to 1% for Class B and 1% for Class C, of the value of the shares redeemed. For the six months ended March 31, 2009, the CDSC for Class B and C shares aggregated $21,012 and $2,193, respectively. A deferred sales charge of up to 1% is assessed on certain redemptions of Class A shares. For the six months ended March 31, 2009, DIDI received $1,968 for Class A shares.

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 six months ended March 31, 2009, the amount charged to the Fund by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $12,102, of which $5,282 is unpaid.

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

Cash Management QP Trust. Pursuant to an Exemptive Order issued by the SEC, the Fund may invest in the Cash Management QP Trust (the "QP Trust"), and other affiliated funds managed by the Advisor. The QP Trust seeks to provide as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. The QP Trust does not pay the Advisor a management fee for the affiliated funds' investments in the QP Trust.

D. Fee Reductions

The Fund 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 Fund's custodian expenses. During the six months ended March 31, 2009, the Fund's custodian fee was reduced by $101 and $35, respectively, for custody and transfer agent credits earned.

E. Line of Credit

The Fund and other affiliated funds (the "Participants") share in a $490 million revolving credit facility provided by a syndication of banks. The Fund may borrow for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee which is allocated based on net assets, among each of the Participants. Interest is calculated at the Federal Funds Rate plus 0.35 percent. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement.

Summary of Management Fee Evaluation by Independent Fee Consultant

October 24, 2008

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

Qualifications

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

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

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

Evaluation of Fees for each DWS Fund

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

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

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

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

Fees and Expenses Compared with Other Funds

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

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

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

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

DeAM's Fees for Similar Services to Others

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

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

Costs and Profit Margins

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

Economies of Scale

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

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

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

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

Quality of Service — Performance

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

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

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

Complex-Level Considerations

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

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

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

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

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

Findings

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

Summary of Administrative Fee Evaluation by Independent Fee Consultant

September 29, 2008

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

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

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

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