Performance in the Average Annual Total Returns table above and the Growth of an Assumed $10,000 Investment line graph that follows is historical and does not guarantee future results. Investment return and principal fluctuate, so your shares may be worth more or less when redeemed. Current performance may differ from performance data shown. Please visit www.dws-investments.com for the Fund's most recent month-end performance. Performance includes reinvestment of all distributions.

The gross expense ratios of the Fund, as stated in the fee table of the prospectus dated February 1, 2009 are 1.37%, 2.19%, 2.12%, 1.01% and 1.04% for Class A, Class B, Class C, Class S and Institutional Class shares, respectively, and may differ from the expense ratios disclosed in the Financial Highlights tables in this report.

Index returns assume reinvestment of dividends and, unlike Fund returns, do not reflect any fees or expenses. It is not possible to invest directly into an index.

Performance figures do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares.

Returns shown for Class A, B and C shares for the period prior to their inception on June 28, 2002 and for Class S shares for the periods prior to its inception on February 1, 2005 are derived from the historical performance of Investment Class shares of DWS Mid Cap Growth Fund during such periods and have been adjusted to reflect the higher total annual operating expenses of each specific class. On October 20, 2006, Investment Class shares were converted into Class S shares. Any difference in expenses will affect performance.

At the close of business on August 31, 2000, shares of Equity Appreciation — Institutional Class merged into Institutional Class shares of DWS Mid Cap Growth Fund. Equity Appreciation — Institutional Class was managed by the same investment management team with the same objectives, policies and strategies as DWS Mid Cap Growth. The performance shown for the 10-year period reflects Equity Appreciation — Institutional Class shares' actual returns prior to August 31, 2000. Performance for periods after August 31, 2000 reflects the performance of DWS Mid Cap Growth Fund — Institutional Class.

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 B shares of 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 (April 1, 2009 to September 30, 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.

* Expenses are equal to the Fund's annualized expense ratio for each share class, multiplied by the average account value over the period, multiplied by the number of days in the most recent six-month period, then divided by 365.

Market Overview and Fund Performance

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.

The past 12 months saw two starkly contrasting periods of stock market performance. The period from October 2008 through February 2009 was as difficult as we have seen in the recent history of the financial markets. During that time, all segments of the stock market were down significantly — growth stocks, value stocks, and large and small caps, as well as commodity-related issues. Much of the turbulence can be traced back to the housing crisis and the extreme buildup of debt among US banks, businesses and consumers. The dissolution of Lehman Brothers in September 2008 brought the crisis to a head, sending the global economy into the worst downturn since the Great Depression. However, the US Federal Reserve Board (the Fed) and the US government mounted a wide-scale response to the financial and economic crises, lowering interest rates significantly and creating lending facilities in an attempt to restore credit flows among banks and businesses. Lending facilities provide financial institutions with access to funds in order to satisfy reserve requirements using the overnight lending market.

On March 9, 2009, the stock market hit its most recent low point, and then began to turn around as some economic data that was characterized as "less negative" caught the attention of investors. In particular, market watchers registered some hope regarding manufacturing data, and even consumer confidence began to move in a more positive direction. In late March, we began to purchase more economically sensitive issues in areas such as industrials (machinery/construction companies, electrical equipment, commercial aerospace, trucking) and commodity-related stocks (oil & gas exploration and production, coal, metals/mining), which had been badly beaten down. Over the months from March through September 2009, a strong market rally took shape, as manufacturing activity continued to pick up and second-quarter gross domestic product (GDP, the value of all goods and services produced in the economy), though still low, was much improved over the previous quarter. In addition, investors were encouraged by the fact that more and more companies were finding a way to access financing, whether through banks or by issuing equity or debt. Several "green shoots" (in other words, emerging signs of economic recovery) indicating preliminary economic recovery materialized throughout the past six months, supportive of a more hospitable investment climate in the coming year.

For its most recent fiscal year ended September 30, 2009, Class A shares of DWS Mid Cap Growth Fund returned -11.52% (unadjusted for sales charges), underperforming the Russell Midcap™ Growth Index return of - -0.40% and the Lipper Mid-Cap Growth Funds category average return of - -2.74%.¹ However, for the six months ended September 30, 2009, the fund performed well, posting a 38.41% return, compared with 41.89% and 38.37% returns for the benchmark and the fund's Lipper category average, respectively.² (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 6 for complete performance information.)

The fund's investment process continues to maintain a long-term perspective and a disciplined, fundamental approach to identifying quality mid-cap growth stocks. We conduct rigorous research to identify compelling opportunities and to build a well-diversified portfolio. We believe that bottom-up research and strategic allocation across the "four building blocks of growth" (stable growth, growth at value prices, high/explosive growth and growth with a catalyst) can lead to attractive risk-adjusted returns, because this approach strategically balances growth against risk in the portfolio. Apart from analyzing company fundamentals, we also use a qualitative scoring system to rank candidates for the portfolio by management quality, competitive positioning, earnings stability and other factors.

Positive Contributors to Fund Performance

For the period, the one positive sector contribution to the fund's stock selection came from energy stocks. The largest individual contributors within the energy sector included Range Resources Corp. and Petrohawk Energy Corp. Both companies engage in exploration and production, drilling for natural gas in prolific shale areas, including the Marcellus (Pennsylvania, New York, Ohio and West Virginia) and Haynesville (Northern Louisiana and East Texas) formations, respectively. Sector allocation had a slightly positive effect on performance for the 12-month period.

The top individual security-level contributors to relative performance during the period included Priceline.com, Inc., Broadcom Corp. and Marvell Technology Group Ltd. Priceline, an on-line travel agent used by consumers for booking hotels, flights and vacation packages, performed strongly this past period as consumers responded positively to the company's model for supplying more attractive travel-related pricing. Broadcom, a market leader in communication integrated circuits, benefited from its dominant position in the growing market for "smartphones." And Marvell, which designs integrated circuits in the area of hard disk drives and Ethernet integrated circuits, has executed well throughout the downturn by implementing cost reduction programs earlier than most other semiconductor companies.

Negative Contributors to Fund Performance

The largest individual detractors from performance on a company level included Affiliated Managers Group, Inc., Covance, Inc. and Herbalife Ltd. In the case of Affiliated Managers, which acquires majority interests in midsize investment management firms, continuing turbulence in the financial markets prompted a significant sell-off in this stock. For Covance, which conducts drug testing trials for pharmaceutical and biotechnology companies, the firm's research bookings have slowed, driven by client cost-cutting due to the uncertain economic environment. The fund trimmed its holdings in Covance but still believes the company is positioned for future growth. Herbalife, which sells health-enhancement products by recruiting individuals to market directly to the public, saw its earnings falter in late 2008 when the company was unable to recruit a sufficient number of new salespeople. We now hold a smaller, but still significant, position in Herbalife shares, which have recovered somewhat during the past several months.

Outlook and Positioning

Cyclical US economic recoveries are normally supported by a rebound in housing, consumer spending on durable goods, higher full-time employment rates and a strong inventory restocking cycle. Modest improvement in some of the above data over the past few months has offered investors a sense of cautious optimism. In fact, the leading manufacturing and consumer confidence indices are back above pre-Lehman Brothers bankruptcy levels, an encouraging sign and a signal that the investment climate could be more hospitable in the coming months. We believe that positive momentum for stocks should continue into 2010, supported by an improved economic climate. We also believe that higher-quality growth stocks, which have thus far trailed riskier, non-earning and highly leveraged issues, will reemerge. Of course, risks remain — mounting US unemployment in particular — causing some investors to worry that the slight economic upturn may not prove to be as strong as hoped.

At present, valuations for mid-cap growth companies appear attractive, as an improving economy would seem to support more visible earnings growth next year. In addition, declining volatility and already lowered earnings expectations could set the stage for mid-cap outperformance in 2010. We believe that our long-term investment horizon permits us to participate in the success of quality growth stocks as they graduate from mid- to large-cap categories over time.

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 September 30, 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.

Notes to Financial Statements

A. Organization and Significant Accounting Policies

DWS Mid Cap Growth Fund (the "Fund") is a diversified series of DWS Advisor Funds (the "Trust"), which is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end investment management 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 a limited group of investors, are not subject to initial or contingent deferred sales charges and have lower ongoing expenses than other classes. 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 they trade. 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.

Disclosure about the classification of fair value measurements is included in a table following the Fund's Investment Portfolio.

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, 2009, the Fund had a net tax basis capital loss carryforward of approximately $84,680,000, including $70,456,000 inherited from its merger with affiliated funds in fiscal year 2005, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until September 30, 2010 ($44,123,000), September 30, 2011 ($25,880,000), September 30, 2012 ($454,000) and September 30, 2017 ($14,223,000), the respective expiration dates, whichever occurs first and which may be subject to certain limitations under Section 382-384 of the Internal Revenue Code. Due to these limitations, approximately $2,976,000 of the inherited capital loss carryforward cannot be used by the Fund, and is not included in the capital loss carryforward of $84,680,000 disclosed above.

In addition, from November 1, 2008 through September 30, 2009, the Fund incurred approximately $112,893,000 of net realized capital losses. As permitted by tax regulations, the Fund intends to elect to defer these losses and treat them as arising in the fiscal year ending September 30, 2010.

The Fund has reviewed the tax positions for the open tax years as of September 30, 2009 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 in-kind redemptions, net investment losses incurred by the Fund and 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.

At September 30, 2009, the Fund's components of distributable earnings (accumulated losses) on a tax-basis were as follows:

Capital loss carryforwards	$ (84,680,000)
Net unrealized appreciation (depreciation) on investments	$ 53,370,034

In addition, the tax character of distributions paid to shareholders by the Fund is summarized as follows:

	Years Ended September 30,
	2009	2008
Distributions from long-term capital gains	$ —	$ 161,488,413
Return of capital	$ 45,489	$ —

Redemption Fees. During the year, the Fund imposed a redemption fee of 2% of the total redemption amount on all Fund shares redeemed or exchanged within 15 days of buying them, either by purchase or exchange. This fee was assessed and retained by the Fund for the benefit of the remaining shareholders. The redemption fee was accounted for as an addition to paid-in capital. The Fund no longer imposes the 2% redemption fee on Fund shares acquired (either by purchase or exchange) on or after June 1, 2009.

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 year ended September 30, 2009, purchases and sales of investment securities (excluding short-term investments) aggregated $326,405,443 and $449,359,020, 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.

("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 fees it receives from the Fund. For the year ended September 30, 2009, the amounts charged to the Fund by DISC were as follows:

("DIDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.75%, of average daily net assets of each of Class B and C shares. In accordance with the Fund's Underwriting and Distribution Services Agreement, DIDI enters into related selling group agreements with various firms at various rates for sales of Class B and C shares. For the year ended September 30, 2009, the Distribution Fee was as follows:

In addition, DIDI provides information and administrative services for a fee ("Service Fee") to Class A, B and C 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 year ended September 30, 2009, the Service Fee was as follows:

Service Fee	Total Aggregated	Unpaid at September 30, 2009	Annual Effective Rate
Class A	$ 373,527	$ 107,928	.24%

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 year ended September 30, 2009 aggregated $13,384.

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 year ended September 30, 2009, the CDSC for the Fund's Class B and C shares was $17,852 and $1,419, respectively. A deferred sales charge of up to 1% is assessed on certain redemptions of Class A shares. For the year ended September 30, 2009, DIDI received $10.

Typesetting and Filing Service Fees. Under an agreement withDIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Fund.

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.

Affiliated Cash Management Vehicles. The Fund may invest cash balances that have not been invested in portfolio securities in affiliated funds managed by the Advisor. Prior to October 2, 2009, the Fund invested in Cash Management QP Trust (the "QP Trust"). Effective October 2, 2009, the QP Trust merged into the Central Cash Management Fund. The Central Cash Management Fund seeks to provide as high a level of current income as is consistent with the preservation of capital and the maintenance of liquidity. Affiliated cash management vehicles do not pay the Advisor a management fee.

D. Line of Credit

The Fund and other affiliated funds (the "Participants") share in a $450 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 a rate per annum equal to the sum of the Federal Funds Rate plus 1.25 percent plus if LIBOR exceeds the Federal Funds Rate the amount of such excess. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement.

F. In-Kind Redemptions

In certain circumstances, the Fund may distribute portfolio securities rather than cash as payments for a redemption of fund shares (in-kind redemption). For financial reporting purposes, the Fund recognizes a gain on in-kind redemptions to the extent the value of the distributed securities exceeds their costs; the Fund recognizes a loss if cost exceeds value. Gains and losses realized on in-kind redemptions are not recognized for tax purposes, and are reclassified from undistributed realized gain (loss) to paid-in capital. During the year ended September 30, 2008, the Fund realized $79,982,687 of net gain attributable to in-kind redemptions.

G. Payments Made by Affiliates

During the year ended September 30, 2009, the Advisor fully reimbursed the Fund $2,097 for losses incurred on trades executed incorrectly. The amounts of the losses were less than 0.01% of the Fund's average net assets, thus having no impact on the Fund's total return.

H. Review for Subsequent Events

Management has reviewed the events and transactions from October 1, 2009 through November 20, 2009, the date the financial statements were available to be issued, for subsequent events, and has determined that there were no material events that would require disclosure in the Fund's financial statements through this date.

Report of Independent Registered Public Accounting Firm

To the Trustees of DWS Advisor Funds and Shareholders of DWS Mid Cap Growth Fund:

In our opinion, the accompanying statement of assets and liabilities, including the investment portfolio, and 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 DWS Mid Cap Growth Fund (the "Fund") at September 30, 2009, 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 statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit 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 September 30, 2009 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

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. ("DWS") in September 2009.

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

• In September 2009, all but one of the Fund's Trustees were independent of DWS and its affiliates.

• The Trustees meet frequently to discuss fund matters. Each year, the Trustees dedicate substantial time to contract review matters. Over the course of several months, the Board's Contract Committee, in coordination with the Board's Equity Oversight Committee, reviewed comprehensive materials received from DWS, 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 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 DWS 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 DWS managed the Fund, and that the Agreement was approved by the Fund's shareholders. DWS 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 DWS'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, DWS provides portfolio management services to the Fund and that, pursuant to a separate administrative services agreement, DWS 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 DWS to attract and retain high-quality personnel, and the organizational depth and stability of DWS. 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 Lipper Inc. ("Lipper"). The Board also noted that it has put into place a process of identifying "Focus Funds" (e.g., funds performing poorly relative to their benchmark or a peer universe compiled by Lipper), and receives more frequent reporting and information from DWS regarding such funds, along with DWS'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, 2008, the Fund's performance (Class A shares) was in the 4th quartile of the applicable Lipper universe (the 1st quartile being the best performers and the 4th quartile being the worst performers). The Board also observed that the Fund has underperformed its benchmark in each of the one-, three- and five-year periods ended December 31, 2008. The Board noted the disappointing investment performance of the Fund in recent periods and continued to discuss with senior management of DWS the factors contributing to such underperformance and actions being taken to improve performance. The Board observed that the Fund had experienced improved relative performance during the first seven months of 2009. The Board recognized that DWS has made significant changes in the Fund's management structure, including the introduction of a new portfolio management team in January 2009.

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 DWS 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 DWS 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, 2008). The Board also reviewed data comparing each share class's total (net) operating expenses to the applicable Lipper expense universe. The Board concluded that the comparative Lipper operating expense data was of limited utility, as it likely significantly understated the current expense ratios of many peer funds due to the substantial declines in net assets as a result of market losses and net redemptions that many funds experienced between mid-September 2008 and March 2009 and that were not reflected in the data. The Board also noted that the expense limitations agreed to by DWS helped to ensure that the Fund's total (net) operating expenses would remain competitive.

The information considered by the Board as part of their review of management fees included information regarding fees charged by DWS and its affiliates to similar institutional accounts and to similar funds managed by the same portfolio management teams but offered primarily to European investors ("DWS Europe funds"), in each case as applicable. The Board observed that advisory fee rates for institutional accounts generally were lower than the management fees charged by similarly managed DWS US mutual funds ("DWS Funds"), but also took note of the differences in services provided to DWS Funds as compared to institutional accounts. In the case of DWS Europe funds, the Board observed that fee rates for DWS Europe funds generally were higher than for similarly managed DWS Funds, but noted that differences in the types of services provided to DWS Funds relative to DWS Europe funds made it difficult to compare such fees.

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 DWS.

Profitability. The Board reviewed detailed information regarding revenues received by DWS under the Agreement. The Board considered the estimated costs and pre-tax profits realized by DWS 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 DWS and its affiliates with respect to all fund services in totality and by fund. The Board reviewed DWS'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 DWS 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), DWS and its affiliates' overall profitability with respect to the DWS fund complex (after taking into account distribution and other services provided to the funds by DWS and its affiliates) was lower than the overall profitability levels of many comparable firms for which such data was available.

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

Other Benefits to DWS and Its Affiliates. The Board also considered the character and amount of other incidental benefits received by DWS and its affiliates, including any fees received by DWS for administrative services provided to the Fund and any fees received by an affiliate of DWS for distribution services. The Board also considered benefits to DWS 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 DWS related to DWS Funds advertising and cross-selling opportunities among DWS 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 DWS to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of both DWS's chief compliance officer and the Fund's chief compliance officer; (ii) the large number of DWS compliance personnel; and (iii) the substantial commitment of resources by DWS and its affiliates to compliance matters.

Based on all of the information considered and the conclusions reached, the Board unanimously (including 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 9, 2009, As Revised November 20, 2009

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 2009, 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 and 2008.

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 and serve 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 124 publicly offered 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.

ITEM 2.	CODE OF ETHICS
	As of the end of the period, September 30, 2009, DWS Mid Cap Growth Fund has a code of ethics, as defined in Item 2 of Form N-CSR, that applies to its Principal Executive Officer and Principal Financial Officer. There have been no amendments to, or waivers from, a provision of the code of ethics during the period covered by this report that would require disclosure under Item 2. A copy of the code of ethics is filed as an exhibit to this Form N-CSR.
ITEM 3.	AUDIT COMMITTEE FINANCIAL EXPERT
	The Funds’ audit committee is comprised solely of trustees who are “independent” (as such term has been defined by the Securities and Exchange Commission (“SEC”) in regulations implementing Section 407 of the Sarbanes-Oxley Act (the “Regulations”)). The Funds’ Board of Trustees has determined that there are several “audit committee financial experts” (as such term has been defined by the Regulations) serving on the Funds’ audit committee including Mr. William McClayton, the chair of the Funds’ audit committee. The SEC has stated that an audit committee financial expert is not an “expert” for any purpose, including for purposes of Section 11 of the Securities Act of 1933 and the designation or identification of a person as an audit committee financial expert pursuant to this Item 3 of Form N-CSR does not impose on such person any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such person as a member of the audit committee and board of directors in the absence of such designation or identification.

Generally, each Fund’s Audit Committee must pre approve (i) all services to be performed for a Fund by a Fund’s Independent Registered Public Accounting Firm and (ii) all non-audit services to be performed by a Fund’s Independent Registered Public Accounting Firm for the DIMA Entities with respect to operations and financial reporting of the Fund, except that the Chairperson or Vice Chairperson of each Fund’s Audit Committee may grant the pre-approval for non-audit services described in items (i) and (ii) above for non-prohibited services for engagements of less than $100,000. All such delegated pre approvals shall be presented to each Fund’s Audit Committee no later than the next Audit Committee meeting.

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception under Rule 2-01 of Regulation S-X.

According to the registrant’s principal Independent Registered Public Accounting Firm, all of the principal Independent Registered Public Accounting Firm's hours spent on auditing the registrant's financial statements were attributed to work performed by full-time permanent employees of the principal Independent Registered Public Accounting Firm.

***

PwC advised the Fund's Audit Committee that PwC has identified two matters that it determined to be inconsistent with the SEC's auditor independence rules. In the first instance, an employee of PwC had power of attorney over an account which included DWS funds. The employee did not perform any audit services for the DWS Funds, but did work on a non audit project for Deutsche Bank AG. In the second instance, an employee of PwC served as a nominee shareholder (effectively equivalent to a Trustee) of various companies/trusts since 2001. Some of these companies held shares of Aberdeen, a sub advisor to certain DWS Funds, and of certain funds sponsored by subsidiaries of Deutsche Bank AG. The trustee relationship has ceased. PwC informed the Audit Committee that these matters could have constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X. PwC advised the Audit Committee that PwC believes its independence had not been impacted as it related to the audits of the Fund. In reaching this conclusion, PwC noted that during the time of its audit, the engagement team was not aware of the investment and that PwC does not believe these situations affected PwC's ability to act objectively and impartially and to issue a report on financial statements as the funds' independent auditor.

I.

Overview

This Principal Executive Officer and Principal Financial Officer Code of Ethics (“Officer Code”) sets forth the policies, practices, and values expected to be exhibited in the conduct of the Principal Executive Officers and Principal Financial Officers of the investment companies (“Funds”) they serve (“Covered Officers”). A list of Covered Officers and Funds is included on Appendix A.

The Boards of the Funds listed on Appendix A have elected to implement the Officer Code, pursuant to Section 406 of the Sarbanes-Oxley Act of 2002 and the SEC’s rules thereunder, to promote and demonstrate honest and ethical conduct in their Covered Officers.

Deutsche Asset Management, Inc. or its affiliates (“DeAM”) serves as the investment adviser to each Fund. All Covered Officers are also employees of DeAM or an affiliate. Thus, in addition to adhering to the Officer Code, these individuals must comply with DeAM policies and procedures, such as the DeAM Code of Ethics governing personal trading activities, as adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940.¹ In addition, such individuals also must comply with other applicable Fund policies and procedures.

The DeAM Compliance Officer, who shall not be a Covered Officer and who shall serve as such subject to the approval of the Fund’s Board (or committee thereof), is primarily responsible for implementing and enforcing this Code. The Compliance Officer has the authority to interpret this Officer Code and its applicability to particular circumstances. Any questions about the Officer Code should be directed to the DeAM Compliance Officer.

The DeAM Compliance Officer and his or her contact information can be found in Appendix A.

 

II. Purposes of the Officer Code

The purposes of the Officer Code are to deter wrongdoing and to:

• promote honest and ethical conduct among Covered Officers, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

• promote full, fair, accurate, timely and understandable disclosures in reports and documents that the Funds file with or submit to the SEC (and in other public communications from the Funds) and that are within the Covered Officer’s responsibilities;

• promote compliance with applicable laws, rules and regulations;

• encourage the prompt internal reporting of violations of the Officer Code to the DeAM Compliance Officer; and

• establish accountability for adherence to the Officer Code.

_________________________

¹ The obligations imposed by the Officer Code are separate from, and in addition to, any obligations imposed under codes of ethics adopted pursuant to Rule 17j-1 under the Investment Company Act of 1940, and any other code of conduct applicable to Covered Officers in whatever capacity they serve. The Officer Code does not incorporate any of those other codes and, accordingly, violations of those codes will not necessarily be considered violations of the Officer Code and waivers granted under those codes would not necessarily require a waiver to be granted under this Code. Sanctions imposed under those codes may be considered in determining appropriate sanctions for any violation of this Code.

Any questions about the Officer Code should be referred to DeAM’s Compliance Officer.

 

III. Responsibilities of Covered Officers

 

A. Honest and Ethical Conduct

It is the duty of every Covered Officer to encourage and demonstrate honest and ethical conduct, as well as adhere to and require adherence to the Officer Code and any other applicable policies and procedures designed to promote this behavior. Covered Officers must at all times conduct themselves with integrity and distinction, putting first the interests of the Fund(s) they serve. Covered Officers must be honest and candid while maintaining confidentiality of information where required by law, DeAM policy or Fund policy.

Covered Officers also must, at all times, act in good faith, responsibly and with due care, competence and diligence, without misrepresenting or being misleading about material facts or allowing their independent judgment to be subordinated. Covered Officers also should maintain skills appropriate and necessary for the performance of their duties for the Fund(s). Covered Officers also must responsibly use and control all Fund assets and resources entrusted to them.

Covered Officers may not retaliate against others for, or otherwise discourage the reporting of, actual or apparent violations of the Officer Code or applicable laws or regulations. Covered Officers should create an environment that encourages the exchange of information, including concerns of the type that this Code is designed to address.

 

B. Conflicts of Interest

A “conflict of interest” occurs when a Covered Officer’s personal interests interfere with the interests of the Fund for which he or she serves as an officer. Covered Officers may not improperly use their position with a Fund for personal or private gain to themselves, their family, or any other person. Similarly, Covered Officers may not use their personal influence or personal relationships to influence decisions or other Fund business or operational matters where they would benefit personally at the Fund’s expense or to the Fund’s detriment. Covered Officers may not cause the Fund to take action, or refrain from taking action, for their personal benefit at the Fund’s expense or to the Fund’s detriment. Some examples of conflicts of interest follow (this is not an all-inclusive list): being in the position of supervising, reviewing or having any influence on the job evaluation, pay or benefit of any immediate family member who is an employee of a Fund service provider or is otherwise associated with the Fund; or having an ownership interest in, or having any consulting or employment relationship with, any Fund service provider other than DeAM or its affiliates.

Certain conflicts of interest covered by this Code arise out of the relationships between Covered Officers and the Fund that already are subject to conflict of interest provisions in the Investment Company Act and the Investment Advisers Act. For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as “affiliated persons” of the Fund. Covered Officers must comply with applicable laws and regulations. Therefore, any violations of existing statutory and regulatory prohibitions on individual behavior could be considered a violation of this Code.

As to conflicts arising from, or as a result of the advisory relationship (or any other relationships) between the Fund and DeAM, of which the Covered Officers are also officers or employees, it is recognized by the Board that, subject to DeAM’s fiduciary duties to the Fund, the Covered Officers will in the normal course of their duties (whether formally for the Fund or for DeAM, or for both) be involved in establishing policies and implementing decisions which will have different effects on DeAM and the Fund. The Board recognizes that the participation of the Covered Officers in such activities is inherent in the contract relationship between the Fund and DeAM, and is consistent with the expectation of the Board of the performance by the Covered Officers of their duties as officers of the Fund.

Covered Officers should avoid actual conflicts of interest, and appearances of conflicts of interest, between the Covered Officer’s duties to the Fund and his or her personal interests beyond those contemplated or anticipated by applicable regulatory schemes. If a Covered Officer suspects or knows of a conflict or an appearance of one, the Covered Officer must immediately report the matter to the DeAM Compliance Officer. If a Covered Officer, in lieu of reporting such a matter to the DeAM Compliance Officer, may report the matter directly to the Fund’s Board (or committee thereof), as appropriate (e.g., if the conflict involves the DeAM Compliance Officer or the Covered Officer reasonably believes it would be futile to report the matter to the DeAM Compliance Officer).

When actual, apparent or suspected conflicts of interest arise in connection with a Covered Officer, DeAM personnel aware of the matter should promptly contact the DeAM Compliance Officer. There will be no reprisal or retaliation against the person reporting the matter.

Upon receipt of a report of a possible conflict, the DeAM Compliance Officer will take steps to determine whether a conflict exists. In so doing, the DeAM Compliance Officer may take any actions he or she determines to be appropriate in his or her sole discretion and may use all reasonable resources, including retaining or engaging legal counsel, accounting firms or other consultants, subject to applicable law.² The costs associated with such actions may be borne by the Fund, if appropriate, after consultation with the Fund’s Board (or committee thereof). Otherwise, such costs will be borne by DeAM or other appropriate Fund service provider.

After full review of a report of a possible conflict of interest, the DeAM Compliance Officer may determine that no conflict or reasonable appearance of a conflict exists. If, however, the DeAM Compliance Officer determines that an actual conflict exists, the Compliance Officer will resolve the conflict solely in the interests of the Fund, and will report the conflict and its resolution to the Fund’s Board (or committee thereof). If the DeAM Compliance Officer determines that the appearance of a conflict exists, the DeAM Compliance Officer will take appropriate steps to remedy such appearance. In lieu of determining whether a conflict exists and/or resolving a conflict, the DeAM Compliance Officer instead may refer the matter to the Fund’s Board (or committee thereof), as appropriate. However, the DeAM Compliance Officer must refer the matter to the Fund’s Board (or committee thereof) if the DeAM Compliance Officer is directly involved in the conflict or under similar appropriate circumstances.

After responding to a report of a possible conflict of interest, the DeAM Compliance Officer will discuss the matter with the person reporting it (and with the Covered Officer at issue, if different) for purposes of educating those involved on conflicts of interests (including how to detect and avoid them, if appropriate).

_________________________

² For example, retaining a Fund’s independent accounting firm may require pre-approval by the Fund’s audit committee.

Appropriate resolution of conflicts may restrict the personal activities of the Covered Officer and/or his family, friends or other persons.

Solely because a conflict is disclosed to the DeAM Compliance Officer (and/or the Board or Committee thereof) and/or resolved by the DeAM Compliance Officer does not mean that the conflict or its resolution constitutes a waiver from the Code’s requirements.

Any questions about conflicts of interests, including whether a particular situation might be a conflict or an appearance of one, should be directed to the DeAM Compliance Officer.

 

C. Use of Personal Fund Shareholder Information

A Covered Officer may not use or disclose personal information about Fund shareholders, except in the performance of his or her duties for the Fund. Each Covered Officer also must abide by the Funds’ and DeAM’s privacy policies under SEC Regulation S-P.

 

D. Public Communications

In connection with his or her responsibilities for or involvement with a Fund’s public communications and disclosure documents (e.g., shareholder reports, registration statements, press releases), each Covered Officer must provide information to Fund service providers (within the DeAM organization or otherwise) and to the Fund’s Board (and any committees thereof), independent auditors, government regulators and self-regulatory organizations that is fair, accurate, complete, objective, relevant, timely and understandable.

Further, within the scope of their duties, Covered Officers having direct or supervisory authority over Fund disclosure documents or other public Fund communications will, to the extent appropriate within their area of responsibility, endeavor to ensure full, fair, timely, accurate and understandable disclosure in Fund disclosure documents. Such Covered Officers will oversee, or appoint others to oversee, processes for the timely and accurate creation and review of all public reports and regulatory filings. Within the scope of his or her responsibilities as a Covered Officer, each Covered Officer also will familiarize himself or herself with the disclosure requirements applicable to the Fund, as well as the business and financial operations of the Fund. Each Covered Officer also will adhere to, and will promote adherence to, applicable disclosure controls, processes and procedures, including DeAM’s Disclosure Controls and Procedures, which govern the process by which Fund disclosure documents are created and reviewed.

To the extent that Covered Officers participate in the creation of a Fund’s books or records, they must do so in a way that promotes the accuracy, fairness and timeliness of those records.

 

E. Compliance with Applicable Laws, Rules and Regulations

In connection with his or her duties and within the scope of his or her responsibilities as a Covered Officer, each Covered Officer must comply with governmental laws, rules and regulations, accounting standards, and Fund policies/procedures that apply to his or her role, responsibilities and duties with respect to the Funds (“Applicable Laws”). These requirements do not impose on Covered Officers any additional substantive duties. Additionally, Covered Officers should promote compliance with Applicable Laws.

If a Covered Officer knows of any material violations of Applicable Laws or suspects that such a violation may have occurred, the Covered Officer is expected to promptly report the matter to the DeAM Compliance Officer.

 

IV. Violation Reporting

 

A. Overview

Each Covered Officer must promptly report to the DeAM Compliance Officer, and promote the reporting of, any known or suspected violations of the Officer Code. Failure to report a violation may be a violation of the Officer Code.

Examples of violations of the Officer Code include, but are not limited to, the following:

• Unethical or dishonest behavior

• Obvious lack of adherence to policies surrounding review and approval of public communications and regulatory filings

• Failure to report violations of the Officer Code

• Known or obvious deviations from Applicable Laws

• Failure to acknowledge and certify adherence to the Officer Code

The DeAM Compliance Officer has the authority to take any and all action he or she considers appropriate in his or her sole discretion to investigate known or suspected Code violations, including consulting with the Fund’s Board, the independent Board members, a Board committee, the Fund’s legal counsel and/or counsel to the independent Board members. The Compliance Officer also has the authority to use all reasonable resources to investigate violations, including retaining or engaging legal counsel, accounting firms or other consultants, subject to applicable law.³ The costs associated with such actions may be borne by the Fund, if appropriate, after consultation with the Fund’s Board (or committee thereof). Otherwise, such costs will be borne by DeAM.

 

B. How to Report

Any known or suspected violations of the Officer Code must be promptly reported to the DeAM Compliance Officer.

 

C. Process for Violation Reporting to the Fund Board

The DeAM Compliance Officer will promptly report any violations of the Code to the Fund’s Board (or committee thereof).

 

D. Sanctions for Code Violations

Violations of the Code will be taken seriously. In response to reported or otherwise known violations, DeAM and the relevant Fund’s Board may impose sanctions within the scope of their respective authority over the Covered Officer at issue. Sanctions imposed by DeAM could include termination of employment. Sanctions imposed by a Fund’s Board could include termination of association with the Fund.

_________________________

³ For example, retaining a Fund’s independent accounting firm may require pre-approval by the Fund’s audit committee.

 

V. Waivers from the Officer Code

A Covered Officer may request a waiver from the Officer Code by transmitting a written request for a waiver to the DeAM Compliance Officer.⁴ The request must include the rationale for the request and must explain how the waiver would be in furtherance of the standards of conduct described in and underlying purposes of the Officer Code. The DeAM Compliance Officer will present this information to the Fund’s Board (or committee thereof). The Board (or committee) will determine whether to grant the requested waiver. If the Board (or committee) grants the requested waiver, the DeAM Compliance Officer thereafter will monitor the activities subject to the waiver, as appropriate, and will promptly report to the Fund’s Board (or committee thereof) regarding such activities, as appropriate.

The DeAM Compliance Officer will coordinate and facilitate any required public disclosures of any waivers granted or any implicit waivers.

 

VI. Amendments to the Code

The DeAM Compliance Officer will review the Officer Code from time to time for its continued appropriateness and will propose any amendments to the Fund’s Board (or committee thereof) on a timely basis. In addition, the Board (or committee thereof) will review the Officer Code at least annually for its continued appropriateness and may amend the Code as necessary or appropriate.

The DeAM Compliance Officer will coordinate and facilitate any required public disclosures of Code amendments.

 

VII. Acknowledgement and Certification of Adherence to the Officer Code

Each Covered Officer must sign a statement upon appointment as a Covered Officer and annually thereafter acknowledging that he or she has received and read the Officer Code, as amended or updated, and confirming that he or she has complied with it (see Appendix B: Acknowledgement and Certification of Obligations Under the Officer Code).

Understanding and complying with the Officer Code and truthfully completing the Acknowledgement and Certification Form is each Covered Officer’s obligation.

The DeAM Compliance Officer will maintain such Acknowledgements in the Fund’s books and records.

VIII. Scope of Responsibilities

A Covered Officer’s responsibilities under the Officer Code are limited to:

_________________________

⁴ Of course, it is not a waiver of the Officer Code if the Fund’s Board (or committee thereof) determines that a matter is not a deviation from the Officer Code’s requirements or is otherwise not covered by the Code.

(1) Fund matters over which the Officer has direct responsibility or control, matters in which the Officer routinely participates, and matters with which the Officer is otherwise involved (i.e., matters within the scope of the Covered Officer’s responsibilities as a Fund officer); and

(2) Fund matters of which the Officer has actual knowledge.

 

IX. Recordkeeping

The DeAM Compliance Officer will create and maintain appropriate records regarding the implementation and operation of the Officer Code, including records relating to conflicts of interest determinations and investigations of possible Code violations.

 

X. Confidentiality

All reports and records prepared or maintained pursuant to this Officer Code shall be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or this Officer Code, such matters shall not be disclosed to anyone other than the DeAM Compliance Officer, the Fund’s Board (or committee thereof), legal counsel, independent auditors, and any consultants engaged by the Compliance Officer.
