Investments in mutual funds involve risk. Some funds have more risk than others. The fund is subject to stock market risk. Stocks of medium-sized companies involve greater risk than securities of larger, more established companies, as they often have limited product lines, markets or financial resources and may be subject to more erratic and abrupt market movements. Please read the fund's prospectus for specific details regarding its investments and risk profile.

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-scudder.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 adjustment for front-end sales charges 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. Investment Class, Class R and Institutional Class shares are not subject to sales charges.

To discourage short-term trading, the Fund imposes a 2% redemption fee on shareholders redeeming shares held less than 30 days, which has the effect of lowering total return.

Returns and rankings during all periods shown 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 periods prior to their inception on June 28, 2002 and Class R shares for the period prior to its inception on July 1, 2003 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 gross total annual operating expenses of each specific class. 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 Mid Cap. The performance shown reflects Equity Appreciation — Institutional Class shares' actual returns from its inception on October 12, 1993. Performance for periods after August 31, 2000 reflects the performance of the Mid Cap Growth Fund — Institutional Class. On October 23, 2006, Investment Class shares were converted into Class S shares. On November 20, 2006, Class R shares were converted into Class A shares.

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, the Fund 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 (April 1, 2006 to September 30, 2006).

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

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

Please note that the expenses shown in these tables are meant to highlight your ongoing expenses only and do not reflect any transaction costs. The "Expenses Paid per $1,000" line of the tables is useful in comparing ongoing expenses only and will not help you determine the relative total expense of owning different funds. If these transaction costs had been included, your costs would have been higher.

* 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.

In the following interview, Lead Portfolio Manager Robert S. Janis discusses DWS Mid Cap Growth Fund's market environment, performance and strategy during the fund's most recent fiscal year ended September 30, 2006.

Q: How did DWS Mid Cap Growth Fund perform during the most recent 12-month period?

A: DWS Mid Cap Growth Fund posted a 3.49% total return for its most recent fiscal year ended September 30, 2006, underperforming both the 7.03% return of its benchmark, the Russell MidCap Growth Index, and the 4.91% average return of its peers, represented by the Lipper Mid-Cap Growth Funds category.¹ (Fund return is for Class A shares; 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 for more complete performance information.)

¹ Source: Lipper Inc. The Lipper Mid-Cap Growth Funds category includes portfolios that invest at least 75% of equity assets in companies with market capitalizations of less than 300% of the dollar-weighted median market capitalization of the middle 1,000 securities of the S&P SuperComposite 1500 Index. These portfolios typically have above-average price-to-earnings ratios and price-to-book ratios compared with the S&P MidCap 400 Index. It is not possible to invest directly into a Lipper category.

A: Over the 12-month period, the top individual security-level contributors to performance included Akamai Technologies, Inc., Celgene Corp. and Terex Corp. Akamai is an Internet software and services company that provides services for accelerating and improving the delivery of content and applications over the Internet. Celgene is a multinational integrated biopharmaceutical company primarily engaged in the discovery, development and commercialization of innovative therapies designed to treat cancer and immune inflammatory-related diseases. Terex Corp. is a diversified global manufacturer of capital equipment focused on delivering customer-relevant solutions for the construction, infrastructure, quarry, mining, shipping, transportation, refining and utility industries.

Detractors from performance included Urban Outfitters, Inc., a "lifestyle" merchandising company that operates specialty retail stores as well as a wholesale division, and Chico's FAS, Inc., a specialty retailer of private-label clothing, accessories and other gift items.

Q: What impact did sector positioning and stock selection have on the fund's results?

A: For the 12-month period, both the fund's sector allocation and overall stock selection represented a drag on performance. While our overweight to financial stocks helped returns, our overweight in the energy sector and our underweight in materials and information technology detracted from the fund's performance.²

² Overweight/underweight — An "overweight" means that a fund holds a higher weighting in a given sector compared with its benchmark index; an "underweight" means that a fund holds a lower weighting in a given sector.

Q: What were the major factors affecting stock market performance during the period?

A: For the 12-month period ended September 30, 2006, mid-cap stocks as represented by the Russell MidCap Growth Index were the strongest performers among growth stocks.³ Within the Russell MidCap Growth Index, the consumer staples, financials, materials, utilities and telecommunications services sectors led the market while energy stocks generated the weakest relative performance.

³ Growth stock — Stock of a company that has displayed above-average earnings growth and is expected to continue to increase profits faster than the overall market. Stocks of such companies usually trade at higher valuations and experience more price volatility than the market as a whole.

In the fall of 2005, the United States endured three major hurricanes and the start of a significant spike in energy prices. Following these events, investors grew more and more concerned that consumer spending would be negatively affected, and consumer-oriented stocks were hit hard, including those held by the fund. Therefore, the fund's large allocation in the consumer discretionary sector hurt its performance later in 2005, but eventually rallied by the end of the fourth quarter of 2005. Since then, the US has experienced no major hurricanes, gas prices peaked and began to recede beginning in late August, and interest rates have stabilized. Consumer stocks, and the fund's holdings in this sector, have begun to benefit from these trends.

Over the past several months, the US economy has downshifted to a growth rate slightly below its long-term trends for periods of recovery. Some moderation in the pace of activity was to be expected, as three years of above-trend growth had absorbed excess capacity and contributed to pushing core inflation (i.e., increases in consumer prices not including food and energy costs) slightly above the US Federal Reserve Board's (the Fed) target range.

At its August and September 2006 meetings, the Fed decided to pause in raising short-term interest rates after 17 straight short-term rate hikes. It did so despite the fact that core inflation was running above the Fed's target range. Fed Chairman Bernanke and the Fed governors felt that the lagged effects of their credit tightening and the ongoing contraction in the housing market would slow economic activity and ease strains on key economic resources. In light of tamer energy prices, they felt that a "soft landing," (i.e., a retraction in economic growth, but without a recession and severe job losses) was possible and would bring inflation in line with their targets. Late in the 12-month period ended September 30, 2006, the US stock market rallied based on falling energy prices and declines in long-term interest rates. Stocks posted gains based on robust growth in the global economy and resulting strength in corporate earnings, and the Dow Jones Industrial Average approached the 12,000 mark.

Q: In light of the results for the most recent period, how do you view the economy and investment markets at present?

A: Looking ahead, market participants appear to be concerned with whether the current economic slowdown will be sufficient to reduce supply pressures on global resources and help contain and ultimately lower inflation without sending the economy into recession. Much depends on the outlook for the housing market, particularly on whether consumers' lessened ability to draw on home equity financing will markedly affect the overall level of consumer spending. We believe that the contraction in the housing market will be felt, but only modestly, because we do not expect housing prices to plunge. In addition, the economy should be helped by the fact that energy prices continue to ease, business finances have stayed strong, and global economic activity remains firm. We expect the US economy to grow, though at a slower pace than in recent years. Of course, risks remain: First, a more severe correction in the housing market than we have already experienced could create a significant downturn in consumer spending as well as employment. On the flip side, the US economy may prove to be more resilient than expected, and require the Fed to hike short-term interest rates further. For the present, financial markets seem confident that the economy will be weak enough to prompt some Fed easing in 2007, but not so weak as to unduly hurt corporate earnings. We continue to maintain our long-term perspective, investing in quality mid-cap growth stocks.

DWS Mid Cap Growth Fund (formerly Scudder Mid Cap Growth Fund) (the "Fund") is a diversified series of DWS Advisor Funds (formerly Scudder 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 currently 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 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 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 no longer available to new investors except under certain circumstances. (Please refer to the Fund's Statement of Additional Information.) Shares of Class AARP were designed for members of AARP. (Please see Note C, under the caption Other Related Parties.) On October 23, 2006, Investment Class shares were converted into Class S shares. On November 20, 2006, the Fund's former Class R shares were converted into Class A shares. (Please see Note I.)

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 fees, service fees, administrator fees, 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.

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 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. 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 the lending agent. Either the Fund or the borrower may terminate the loan. The Fund is subject to all investment risks associated with the value 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. Accordingly, the Fund paid no federal income taxes and no federal income tax provision was required.

At September 30, 2006, the Fund had a net tax basis capital loss carryforward of approximately $162,193,000, including approximately $146,248,000 inherited from its mergers with the Scudder Dynamic Growth Fund, Scudder Development Fund, and Scudder Aggressive Growth Fund (Note H), which may be applied against any realized net taxable gains of each succeeding year until fully utilized or until the expiration dates which range from September 30, 2010, to September 30, 2012, whichever occurs first, and which may be subject to certain limitations under Sections 382-384 of the Internal Revenue Code. During the year ended September 30, 2006 the Fund utilized approximately $77,333,000 of a prior year capital loss carryforward. Due to certain limitations under Sections 382-384 of the Internal Revenue Code, approximately $16,956,000 of inherited capital loss carryforwards cannot be used by the Fund, and is not included in the capital loss carryfoward of $162,193,000 disclosed above.

In July 2006, the Financial Accounting Standards Board (FASB) issued Interpretation No. 48, "Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109" (the "Interpretation"). The Interpretation establishes for the Fund a minimum threshold for financial statement recognition of the benefit of positions taken in filing tax returns (including whether the Fund is taxable in certain jurisdictions), and requires certain expanded tax disclosures. The Interpretation is effective for fiscal years beginning after December 15, 2006. Management has begun to evaluate the application of the Interpretation to the Fund and is not in a position at this time to estimate the significance of its impact, if any, on the Fund's financial statements.

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.

At September 30, 2006, the Fund's components of distributable earnings (accumulated losses) on a tax-basis were as follows:

^*For tax purposes, short-term capital gains distributions are considered ordinary income distributions.

Redemption Fees. The Fund imposes a redemption fee of 2% of the total redemption amount on all Fund shares redeemed or exchanged within 30 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. Certain dividends from foreign securities may be recorded subsequent to the ex-dividend date as soon as the Fund is informed of such dividends. Realized gains and losses from investment transactions are recorded on an identified cost basis.

During the year ended September 30, 2006, purchases and sales of investment securities (excluding short-term investments) aggregated $699,102,339 and $834,511,039, respectively.

DWS Scudder is part of Deutsche Asset Management, which is the marketing name in the US for the asset management activities of Deutsche Bank AG. Deutsche Asset Management, Inc. ("DeAM, Inc." or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, is the Fund's Advisor.

Investment Management Agreement. Under the Amended and Restated Investment Management Agreement, 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.

The Fund pays a monthly investment advisory fee, based on the average daily net assets of the Fund, computed and accrued daily and payable monthly, at 1/12 of the annual rates shown below:

Accordingly, for the year ended September 30, 2006, the fee pursuant to the Investment Management Agreement was equivalent to an annual effective rate of 0.62% of the Fund's average daily net assets. The Investment Management was amended and restated effective June 1, 2006.

For the period from October 1, 2005 through January 31, 2009, the Advisor contractually agreed to waive all or a portion of its investment advisory fee and reimburse or pay certain operating expenses of the Fund (excluding expenses such as extraordinary expenses, proxy/shareholder meeting costs, taxes, brokerage and interest) to the extent necessary to maintain the annual expenses of each class as follows:

Administrator Service Fee. Prior to June 1, 2006, Investment Company Capital Corp. ("ICCC" or the "Administrator"), an indirect, wholly owned subsidiary of Deutsche Bank AG, was the Fund's Administrator. For its services as Administrator, ICCC received a fee (the "Administrator Service Fee") of 0.65% of the average daily net assets for Investment Class and Class AARP, 0.45% for Class S shares and 0.40% of average daily net assets for Class A, B, C, R and Institutional Class shares of the Fund, computed and accrued daily and paid monthly. For the period from October 1, 2005 through May 31, 2006, the Administrator Service Fee charged to the Fund was as follows:

Administration Fee. Effective June 1, 2006, the Administration Agreement with ICCC was terminated and the Fund entered into an Administrative Services Agreement with Deutsche Investment Management Americas Inc. ("DeIM"), an indirect wholly owned subsidiary of Deutsche Bank AG, pursuant to which DeIM provides most administrative services to the Fund. For all services provided under the Administrative Services Agreement, the Fund pays DeIM an annual fee ("Administrative Fee") of 0.10% of the Fund's average daily net assets, computed and accrued daily and payable monthly. For the period from June 1, 2006 through September 30, 2006, the Advisor received an Administration Fee of $416,391, of which $101,784 is unpaid.

Service Provider Fees. DWS Scudder Investments Service Company ("DWS-SISC"), an affiliate of the Advisor, is the transfer agent, dividend-paying agent and shareholder service agent for Class A, B, C, Investment, R and Institutional shares. DWS Scudder Service Corporation ("DWS-SSC"), an affiliate of the Advisor, is the transfer agent, dividend-paying agent and shareholder service agent for Class AARP (through July 14, 2006) and S shares. Pursuant to a sub-transfer agency agreement among DWS-SISC, DWS-SSC and DST Systems, Inc. ("DST"), DWS-SISC and DWS-SCC have delegated certain transfer agent and dividend-paying agent functions to DST. DWS-SISC and DWS-SSC compensate DST out of the shareholder servicing fee they receive from the Fund. Prior to June 1, 2006, this fee was included in the Administration Agreement with ICCC. For the period from June 1, 2006 through September 30, 2006, the amounts charged to the Fund by DWS-SISC and DWS-SSC were as follows:

Distribution Service Agreement. Under the Distribution Agreement, in accordance with Rule 12b-1 under the 1940 Act, DWS Scudder Distributors, Inc. ("DWS-SDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.25% of the average daily net assets of the Class A and R shares and 0.75% of average daily net assets of the Class B and C shares. Pursuant to the agreement, DWS-SDI 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, 2006, the Distribution Fee was as follows:

In addition, DWS-SDI provides information and administrative services ("Service Fee") to Class B, C and R shareholders at an annualized rate of up to 0.25% of average daily net assets for each such class. DWS-SDI in turn has various agreements with financial services firms that provide these services and pays these fees based upon the assets of shareholder accounts the firms service. For the year ended September 30, 2006, the Service Fee was as follows:

Underwriting Agreement and Contingent Deferred Sales Charge. DWS-SDI 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, 2006 aggregated $41,531.

In addition, DWS-SDI 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, 2006, the CDSC for the Fund's Class B and C shares was $141,032 and $2,327, respectively. A deferred sales charge of up to 1% is assessed on certain redemptions of Class A shares. For the year ended September 30, 2006, DWS-SDI received $3,751.

Typesetting and Filing Service Fees. Under an agreement with DeIM, DeIM is compensated for providing typesetting and certain regulatory filing services to the Fund. For the year ended September 30, 2006, the amount charged to the Fund by DeIM included in reports to shareholders aggregated $24,960, of which $6,480 is unpaid.

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

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 its Advisor a management fee for the affiliated funds' investments in the QP Trust.

Other Related Parties. Through December 31, 2005, AARP through its affiliate, AARP Services, Inc., monitored and approved the AARP Investment Program from DWS Scudder, but did not act as an investment advisor or recommend specific mutual funds. The contractual relationship between DWS Scudder and AARP ended on December 31, 2005. As a result, the funds are no longer part of the AARP Investment Program and the AARP name and logo was phased out in 2006.

On June 28, 2006, the Board of the Fund approved the conversion of the Class AARP shares of the Fund into the Class S shares of the Fund. This conversion was completed on July 14, 2006 and Class AARP shares are no longer offered.

For the year ended September 30, 2006, the Advisor agreed to reimburse the Fund $23,017, which represented a portion of the expected fee savings for the Advisor through May 31, 2006 related to the outsourcing by the Advisor of certain administrative services to an unaffiliated service provider.

In addition, the Fund has entered into an arrangement with its custodian whereby credits realized as a result of uninvested cash balances are used to reduce a portion of the Fund's custodian expenses. During the year ended September 30, 2006, the Fund's custodian fees were reduced by $170 for custody credits earned.

The Fund and several other affiliated funds (the "Participants") share in a $750 million revolving credit facility administered by JPMorgan Chase Bank N.A. for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee which is allocated, based upon net assets, among each of the Participants. Interest is calculated at the Federal Funds Rate plus 0.5 percent. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement.

⁺ On October 23, 2006, Investment Class shares were converted into Class S shares. On November 20, 2006, Class R shares were converted into Class A shares (see Note I, Subsequent Events).

^* For the period September 16, 2005 (commencement of operations of Class AARP shares) to September 30, 2005.

^** For the period February 1, 2005 (commencement of operations of Class S shares) to September 30, 2005.

^*** On December 17, 2004, the Scudder Dynamic Growth Fund was acquired by the Fund through a tax-free reorganization. On September 16, 2005, the Scudder Aggressive Growth Fund and the Scudder Development Fund were acquired by the Fund through a tax-free organization.

Market Timing Related Regulatory and Litigation Matters. Since at least July 2003, federal, state and industry regulators have been conducting ongoing inquiries and investigations ("inquiries") into the mutual fund industry, and have requested information from numerous mutual fund companies, including DWS Scudder. The DWS funds' advisors have been cooperating in connection with these inquiries and are in discussions with the regulators concerning proposed settlements. Publicity about mutual fund practices arising from these industry-wide inquiries serves as the general basis of a number of private lawsuits against the DWS funds. These lawsuits, which previously have been reported in the press, involve purported class action and derivative lawsuits, making various allegations and naming as defendants various persons, including certain DWS funds, the funds' investment advisors and their affiliates, and certain individuals, including in some cases fund Trustees/Directors, officers, and other parties. Each DWS fund's investment advisor has agreed to indemnify the applicable DWS funds in connection with these lawsuits, or other lawsuits or regulatory actions that may be filed making allegations similar to these lawsuits regarding market timing, revenue sharing, fund valuation or other subjects arising from or related to the pending inquiries. It is not possible to determine with certainty what the outcome of these inquiries will be or what the effect, if any, would be on the funds or their advisors.

With respect to the lawsuits, based on currently available information, the funds' investment advisors believe the likelihood that the pending lawsuits will have a material adverse financial impact on a DWS fund is remote and such actions are not likely to materially affect their ability to perform under their investment management agreements with the DWS funds.

With respect to regulatory matters, Deutsche Asset Management ("DeAM") has advised the funds as follows:

DeAM expects to reach final agreements with regulators in 2006 regarding allegations of improper trading in the DWS funds. DeAM expects that it will reach settlement agreements with the Securities and Exchange Commission ("SEC"), the New York Attorney General and the Illinois Secretary of State providing payment of disgorgement, penalties, and investor education contributions totaling approximately $134 million. Approximately $127 million of this amount would be distributed to shareholders of the affected DWS funds in accordance with a distribution plan to be developed by an independent distribution consultant. DeAM does not believe that any of the DWS funds will be named as respondents or defendants in any proceedings. The funds' investment advisors do not believe these amounts will have a material adverse financial impact on them or materially affect their ability to perform under their investment management agreements with the DWS funds. The above-described amounts are not material to Deutsche Bank, and have already been reserved.

Based on the settlement discussions thus far, DeAM believes that it will be able to reach a settlement with the regulators on a basis that is generally consistent with settlements reached by other advisors, taking into account the particular facts and circumstances of market timing at DeAM and at the legacy Scudder and Kemper organizations prior to their acquisition by DeAM in April 2002. Among the terms of the expected settled orders, DeAM would be subject to certain undertakings regarding the conduct of its business in the future, including maintaining existing management fee reductions for certain funds for a period of five years. DeAM expects that these settlements would resolve regulatory allegations that it violated certain provisions of federal and state securities laws (i) by entering into trading arrangements that permitted certain investors to engage in market timing in certain DWS funds and (ii) by failing more generally to make adequate measures to prevent market timing in the DWS funds, primarily during the 1999-2001 period. With respect to the trading arrangements, DeAM expects that the settlement documents will include allegations related to one legacy DeAM arrangement, as well as three legacy Scudder and six legacy Kemper arrangements. All of these trading arrangements originated in businesses that existed prior to the current DeAM organization, which came together as a result of various mergers of the legacy Scudder, Kemper and Deutsche fund groups, and all of the arrangements were terminated prior to the start of the regulatory investigations that began in the summer of 2003. No current DeAM employee approved the trading arrangements.

There is no certainty that the final settlement documents will contain the foregoing terms and conditions. The independent Trustees/ Directors of the DWS funds have carefully monitored these regulatory investigations with the assistance of independent legal counsel and independent economic consultants.

Other Regulatory Matters. On September 28, 2006, the Securities and Exchange Commission ("SEC") and the National Association of Securities Dealers ("NASD") announced final agreements in which Deutsche Investment Management Americas Inc. ("DeIM"), Deutsche Asset Management, Inc. ("DeAM, Inc.") and Scudder Distributors, Inc. ("SDI") (now known as DWS Scudder Distributors, Inc.) settled administrative proceedings regarding disclosure of brokerage allocation practices in connection with sales of the Scudder Funds' (now known as the DWS Scudder Funds) shares during 2001-2003. The agreements with the SEC and NASD are reflected in orders which state, among other things, that DeIM and DeAM, Inc. failed to disclose potential conflicts of interest to the fund Boards and to shareholders relating to SDI's use of certain funds' brokerage commissions to reduce revenue sharing costs to broker-dealer firms with whom it had arrangements to market and distribute Scudder Fund shares. These directed brokerage practices were discontinued in October 2003.

Under the terms of the settlements, in which DeIM, DeAM, Inc. and SDI neither admitted nor denied any of the regulators' findings, DeIM, DeAM, Inc. and SDI agreed to pay disgorgement, prejudgment interest and civil penalties in the total amount of $19.3 million. The portion of the settlements to be distributed to the funds is approximately $17.8 million and is payable to the funds as prescribed by the settlement orders based upon the amount of brokerage commissions from each fund used to satisfy revenue sharing agreements with broker-dealers who sold fund shares. Accordingly, in September 2006, the Fund recorded a receivable from the Advisor for its settlement portion of $161,678 which is equivalent to $0.002 per share.

As part of the settlements, DeIM, DeAM, Inc. and SDI also agreed to implement certain measures and undertakings relating to revenue sharing payments including making additional disclosures in the fund Prospectuses or Statements of Additional Information, adopting or modifying relevant policies and procedures and providing regular reporting to the fund Boards.

SDI has also offered to settle with the NASD regarding SDI's provision of non-cash compensation to associated persons of NASD member firms and related policies. In the offer, SDI consents to the imposition of a censure by the NASD and a fine of $425,000. The NASD has not yet accepted SDI's offer.

On December 17, 2004, the Fund acquired all of the net assets of Scudder Dynamic Growth Fund pursuant to a plan of reorganization approved by shareholders on December 10, 2004.

In addition, on September 16, 2005, the Fund acquired all of the net assets of Scudder Aggressive Growth Fund and Scudder Development Fund pursuant to a plan of reorganization approved by shareholders on September 2, 2005.

The above shares were exchanged for the following shares outstanding on the date acquired of the Scudder Mid Cap Growth Fund:

The net unrealized appreciation (depreciation) included in the net assets above was as follows:

The aggregate net assets of the Fund immediately before the acquisition were as follows:

The combined net assets of the Fund immediately following the acquisition were as follows:

On June 28, 2006, the Fund's Board approved the conversion of Investment Class shares into the Fund's Class S shares. The conversion of these shares was completed on October 23, 2006, and Investment Class shares are no longer offered by the Fund.

In addition, on June 28, 2006, the Fund's Board approved the conversion of Class R shares into the Fund's Class A shares. This conversion was completed on November 20, 2006, and Class R shares are no longer offered by the Fund.

To the Trustees of DWS Advisor Funds (formerly Scudder 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 (formerly Scudder Mid Cap Growth) (the "Fund") at September 30, 2006, 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, 2006 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

Please consult a tax advisor if you have questions about federal or state income tax laws, or on how to prepare your tax returns. If you have specific questions about your account, please call 1-800-621-1048.

Additional information announced by Deutsche Asset Management regarding the terms of the expected settlements referred to in the Market Timing Related Regulatory and Litigation Matters and Other Regulatory Matters in the Notes to Financial Statements will be made available at www.dws-scudder.com/regulatory_settlements, which will also disclose the terms of any final settlement agreements once they are announced.

A Special Meeting of Shareholders (the "Meeting") of DWS Mid Cap Growth Fund (the "Fund") was held on May 5, 2006, at the offices of Deutsche Asset Management, 345 Park Avenue, New York, New York 10154. At the Meeting, the following matters were voted upon by the shareholders (the resulting votes are presented below).

II-A. Approval of an Amended and Restated Investment Management Agreement with the Fund's Current Investment Advisor.

II-B. Approval of an Amended and Restated Investment Management Agreement with Deutsche Investment Management Americas Inc.

The Meeting was reconvened on June 1, 2006, at which time the following matters were voted upon by the shareholders (the resulting votes are presented below):

I. Election of Board Members. ("Number of Votes" represents all Funds that are series of DWS Advisor Funds.)

V. Approval of Amended and Restated Declaration of Trust. ("Number of Votes" represents all Funds that are series of DWS Advisor Funds.)

* Broker non-votes are proxies received by the Fund from brokers or nominees when the broker or nominee neither has received instructions from the beneficial owner or other persons entitled to vote nor has discretionary power to vote on a particular matter.

The Fund's Trustees approved the continuation of the Fund's current investment advisory agreement with DeAM in September 2006. The Fund's current investment advisory agreement was also approved by the Fund's shareholders at a special meeting held in May 2006 as part of an overall plan to standardize and add flexibility to the management agreements for the DWS funds.

In terms of the process that the Trustees followed prior to approving the agreement, shareholders should know that:

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

The Trustees meet frequently to discuss fund matters. Each year, the Trustees dedicate part or all of several meetings to contract review matters. In connection with reviewing the Fund's investment advisory agreement, the Trustees also review the terms of the Fund's Rule 12b-1 plan, distribution agreement, administration agreement, transfer agency agreement and other material service agreements.

In connection with the Board's 2006 contract review, the Board formed a special committee to facilitate careful review of the funds' contractual arrangements. After reviewing the Fund's arrangements, that committee recommended that the Board vote to approve the continuation of the Fund's investment advisory agreement.

The Trustees regularly meet privately with their independent counsel to discuss contract review and other matters. In addition, the Trustees were also advised by two consultants in the course of their 2006 review of the Fund's contractual arrangements.

DeAM and its predecessors have managed the Fund since inception, and the Trustees believe that a long-term relationship with a capable, conscientious advisor is in the best interest of shareholders. As you may know, DeAM is part of Deutsche Bank, a major global banking institution that is engaged in a wide range of financial services. The Trustees believe that there are significant advantages to being part of a global asset management business that offers a wide range of investing expertise and resources, including hundreds of portfolio managers and analysts with research capabilities in many countries throughout the world.

Shareholders may focus primarily on fund performance and fees, but the Fund's Trustees consider these and many other factors, including the quality and integrity of DeAM's personnel and such other issues as back-office operations, fund valuations, and compliance policies and procedures.

In determining to approve the continuation of the Fund's current investment advisory agreement, the Board considered all factors that it believes relevant to the interests of Fund shareholders, including:

The investment management fee schedule for the Fund, including (i) comparative information provided by Lipper regarding investment management fee rates paid to other investment advisors by similar funds and (ii) fee rates paid to DeAM by similar funds and institutional accounts advised by DeAM (if any). With respect to management fees paid to other investment advisors by similar funds, the Trustees noted that the fee rates paid by the Fund were lower than the median (2nd quartile) of the applicable Lipper peer group (based on Lipper data provided as of December 31, 2005). The Board gave a lesser weight to fees paid by similar institutional accounts advised by DeAM, in light of the material differences in the scope of services provided to mutual funds as compared to those provided to institutional accounts. Taking into account the foregoing, the Board concluded that the fee schedule in effect for the Fund represents reasonable compensation in light of the nature, extent and quality of the investment services being provided to the Fund.

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

The total operating expenses of the Fund. In this regard, the Board noted that the total (net) operating expenses of the Fund (Class A shares) are expected to be lower than the median (1st quartile) of the applicable Lipper expense universe (based on Lipper data provided as of December 31, 2005, and in each case analyzing Class A expenses less any applicable distribution and/or service plan expenses). The Board considered the expenses of this class to be representative for purposes of evaluating other classes of shares. The Board also considered how the Fund's total (net) operating expenses compared to the total (net) operating expenses of a more customized peer group selected by Lipper (based on such factors as asset size). The Board also noted that the expense limitation agreed to by DeAM helped to ensure that the Fund's total (net) operating expenses would be competitive relative to the applicable Lipper universe.

The investment performance of the Fund and DeAM, both absolute and relative to various benchmarks and industry peer groups. The Board noted that for the one-, three- and five-year periods ended June 30, 2006, the Fund's performance (Institutional Class shares) was in the 3rd quartile, 3rd quartile and 2nd quartile, respectively, of the applicable Lipper universe. The Board also observed that the Fund has underperformed its benchmark in the one-, three- and five-year periods ended June 30, 2006. The Board recognized that DeAM has made significant changes in its investment personnel and processes in recent years in an effort to improve long-term performance.

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

The costs of the services to, and profits realized by, DeAM and its affiliates from their relationships with the Fund. The Board reviewed information concerning the costs incurred and profits realized by DeAM during 2005 from providing investment management services to the Fund (and, separately, to the entire DWS Scudder fund complex), and reviewed with DeAM the cost allocation methodology used to determine DeAM's profitability. In analyzing DeAM's costs and profits, the Board also reviewed the fees paid to and services provided by DeAM and its affiliates with respect to administrative services, transfer agent services, shareholder servicing and distribution (including fees paid pursuant to 12b-1 plans), as well as information regarding other possible benefits derived by DeAM and its affiliates as a result of DeAM's relationship with the Fund. As part of this review, the Board considered information provided by an independent accounting firm engaged to review DeAM's cost allocation methodology and calculations. The Board concluded that the Fund's investment management fee schedule represented reasonable compensation in light of the costs incurred by DeAM and its affiliates in providing services to the Fund. The Board also reviewed information regarding the profitability of certain similar investment management firms. The Board noted that while information regarding the profitability of such firms is limited (and in some cases is not necessarily prepared on a comparable basis), Deutsche Asset Management's overall profitability with respect to the DWS Scudder fund complex (after taking into account distribution and other services provided to the funds by DeAM and its affiliates) was lower than the overall profitability levels of many comparable firms for which such data was available.

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

DeAM's commitment to and record of compliance, including its written compliance policies and procedures. In this regard, the Board considered DeAM's commitment to indemnify the Fund against any costs and liabilities related to lawsuits or regulatory actions making allegations regarding market timing, revenue sharing, fund valuation or other subjects arising from or relating to pending regulatory inquiries. The Board also considered the significant attention and resources dedicated by DeAM to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of DeAM's chief compliance officer, who reports to the Board; (ii) the large number of compliance personnel who report to DeAM's chief compliance officer; and (iii) the substantial commitment of resources by Deutsche Asset Management to compliance matters.

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

Based on all of the foregoing, the Board determined to continue the Fund's current investment advisory agreement, and concluded that the continuation of such agreement was in the best interests of the Fund's shareholders.

In reaching this conclusion the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, many of which were in executive session with only the Independent Trustees and their counsel present. It is possible that individual Trustees may have weighed these factors differently in reaching their individual decisions to approve the continuation of the current agreement.

The following table presents certain information regarding the Board Members and Officers of the Trust as of September 30, 2006. Each Board Member's year of birth is set forth in parentheses after his or her name. Unless otherwise noted, (i) each Board Member has engaged in the principal occupation(s) noted in the table for at least the most recent five years, although not necessarily in the same capacity, and (ii) the address of each Independent Board Member is c/o Dawn-Marie Driscoll, PO Box 100176, Cape Coral, FL 33904. The term of office for each Board Member is until the election and qualification of a successor, or until such Board Member sooner dies, resigns, is removed or as otherwise provided in the governing documents of the fund. Because the fund does not hold an annual meeting of shareholders, each Board Member will hold office for an indeterminate period. The Board Members may also serve in similar capacities with other funds in the fund complex.

CODE OF ETHICS.

As of the end of the period, September 30, 2006 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.

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” serving on the Funds’ audit committee. The Board has determined that Keith R Fox, the chair of the Funds’ audit committee, qualifies as an “audit committee financial expert” (as such term has been defined by the Regulations) based on its review of Mr. Fox’s pertinent experience and education. The SEC has stated that 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.
