This report must be preceded or accompanied by a prospectus. To obtain a prospectus for any of our funds, refer to the Account Management Resources information provided in the back of this booklet. We advise you to consider the fund's objectives, risks, charges and expenses carefully before investing. The prospectus contains this and other important information about the fund. Please read the prospectus carefully before you invest.

Investments in mutual funds involve risk. Some funds have more risk than others. The fund invests in individual bonds whose yields and market values fluctuate so that your investment may be worth more or less than its original cost. Bond investments are subject to interest rate risk such that when interest rates rise, the prices of the bonds, and thus the value of the bond fund, may decline and the investor may lose principal value. Investors in the fund should be able to withstand fluctuations in the fixed income markets. The yield and value of the fund changes every day and can be affected by changes in interest rates, general market conditions and other political, social and economic developments, as well as specific matters relating to the companies in whose securities a fund invests. All of these factors may result in greater share price volatility. Please read the fund's prospectus for specific details regarding its investments and risk profile.

Performance Summary October 31, 2006

Classes A, B, C and Institutional

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 2.75%. 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. 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 15 days, which has the effect of lowering total return and rankings.

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.

On August 21, 2006, the fund was reorganized from DWS Short Duration Fund, a series of DWS Investments Trust (the "Predecessor Fund"), into DWS Short Duration Fund, a newly created series of the DWS Advisor Funds. This change in the legal entity had no economic impact relative to accounting or tax. Performance shown prior to August 21, 2006 is derived from the historical performance of the Predecessor Fund.

Returns shown for Class A, B and C shares for the periods prior to their inception on February 28, 2003 are derived from the historical performance of Institutional Class shares of the DWS Short Duration 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.

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 each Fund and to help you compare these expenses with the ongoing expenses of investing in other mutual funds. In the most recent six-month period, the Fund limited these expenses; had it not done so, expenses would have been higher. The example in the table is based on an investment of $1,000 invested at the beginning of the six-month period and held for the entire period (May 1, 2006 to October 31, 2006).

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

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

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

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

Expenses and Value of a $1,000 Investment for the six months ended October 31, 2006
Actual Fund Return	Class A	Class B	Class C	Class S	Institutional Class

Expenses Paid per $1,000*	$ 2.96	$ 6.16	$ 6.16	$ 3.41	$ 2.75

* 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, Gary W. Bartlett, senior portfolio manager for DWS Short Duration Fund, discusses the recent market environment and strategy in managing the fund during its most recent annual period ended October 31, 2006.

Q: How did the bond market perform?

A: The 12-month period ending October 31, 2006 was one of marked change for the bond market. First, the headline event was the changing of the guard at the US Federal Reserve Board (the Fed) as Alan Greenspan stepped down in January and was succeeded as chairman by Ben Bernanke. Second, although not directly linked, the Fed's monetary policy also changed during the period. After 17 consecutive rate hikes beginning in mid-2004, the Fed paused in mid-2006, signaling the end of the tightening regimen. Third, the shape of the Treasury yield curve also altered dramatically over the last 12 months.¹ After beginning the period in a flattening trend, the curve ended the period inverted. The yield on the benchmark 10-year Treasury, despite moving within a wide band of 92 basis points during the year, ended the period only 5 bps higher at 4.60%. The yield on the 2-year treasury closed at 4.70%, up 32 basis points over the period. All in the context of a Fed target rate that, notwithstanding the cessation of tightening, still climbed 1.50% during the early part of the period and remains fixed at 5.25%.

¹ The yield curve is a graph with a left-to-right line that shows how high or low yields are, from the shortest to the longest maturities. Typically (and when the yield curve is characterized as "steep," this is especially true) the line rises from left to right as investors who are willing to tie up their money for a longer period are rewarded with higher yields.

² The Lehman Brothers Aggregate Bond Index is an unmanaged index representing domestic taxable investment-grade bonds, with index components for government and corporate securities, mortgage pass-through securities and asset-backed securities with average maturities of one year or more. The Merrill Lynch 1-3 Year Treasury Index is an unmanaged index consisting of all public US Treasury obligations having maturities from 1 to 2.99 years. Index returns assume reinvestment of all distributions and, unlike fund returns, do not reflect any fees or expenses. It is not possible to invest directly into an index.

For the period, the Lehman Brothers Aggregate Bond Index returned 5.19% and the Merrill Lynch 1-3 Year Treasury Index delivered 4.15%.² In the short (1-3 year) market, generally tighter spreads, albeit slightly, helped most spread sectors to outperform comparable duration treasuries for the period.³ The exception was single-family mortgage-backed securities, which posted negative excess returns as balloons — which we do not currently invest in — underperformed dramatically.

Q: How did the fund perform?

A: For the 12-month period ended October 31, 2006, DWS Short Duration Fund Class A shares returned 4.44 %. (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 10 for the performance of other share classes and more complete performance information.) This compares with 4.10% for the average fund in the Lipper Short Investment-Grade Debt Funds category and 4.15% for the Merrill Lynch 1-3 Year Treasury Index, the fund's benchmark.⁴

³ Spread sectors are non-Treasury bond sectors of the fixed-income market.

⁴ The Lipper Short Investment-Grade Debt Funds category consist of funds that invest primarily in investment-grade debt issues (rated in the top four grades) with dollar-weighted average maturities of less than three years. Lipper figures represent the average of the total returns reported by all of the mutual funds designated by Lipper Inc. as falling into this category. Category returns assume reinvestment of all distributions. It is not possible to invest directly in a Lipper category.

Q: What factors contributed to and detracted from the fund's performance?

A: Our investment in corporate bonds, which had been pared earlier in the year in light of our heightened risk profile, particularly in the context of broadly fair to full market valuations, was increased late in the period as shorter securities reflected better valuations. An area of particular emphasis within our corporate positioning, as well as within the corporate bond market headlines recently, is the broadly defined Hybrid Capital Securities market. This market underperformed early in the year when the regulatory treatment of the securities came under review, causing consternation in the buyer base, and thus widening of their spreads. In recent months, these securities have regained that lost performance, and then some, after it appeared that market participants' and regulators' views of the securities seemed to converge toward our own view of their creditworthiness and structural integrity. In other corporate subsectors, holdings in insurance, which benefited from a benign hurricane season; banks, which reported steady profits; and media cable all aided performance. Sovereign bonds, included in the noncorporate sector, also performed well and our underweight to this credit sector was a drag on performance.⁵

⁵ "Overweight" means the fund holds a higher weighting in a given sector or security than the benchmark. "Underweight" means the fund holds a lower weighting.

Our mortgage positioning remains purposefully positioned in what we view as the cheapest cash flows in the US mortgage market. A combination of last-cash flow hybrid adjustable rate mortgages (ARMs) and PAC bonds make up the majority of our mortgage weighting, while the indices consist entirely of agency pass-throughs. In general, pass-through mortgages have performed well in the context of excess foreign demand and ever-lower volatility. However, in the one-to-three year market, mortgages posted negative returns as balloons underperformed dramatically. We have continued to sell into strong demand, reflecting our view of the technical overvaluation of pass-throughs, largely as a result of the bid from foreign banks, heavily weighted with US dollars to invest from their trade surplus with the United States. Furthermore, the historically low level of volatility has made mortgage valuations in widely used option-adjusted spread (OAS) valuation models more attractive. These benign volatility levels are unlikely to persist for an extended period, and we believe more rational pass-through valuations will result when the normalization ensues. Along with that, valuations of the structured mortgages we presently hold should benefit nicely and aid future performance. While hybrid ARMs have detracted from our relative performance during the most recent quarter, they've been a positive contributor relative to the benchmark for the period, and remain a relatively attractive investment in the front end of the curve.

Our positioning in the asset-backed sector again reflects our views on market valuation relative to fundamentals. With valuations particularly full, we remain relatively conservatively positioned largely in one-year and under asset-backed securities, mostly in the Home Equity Loan sector of the asset-backed securities (ABS) market. This strategy has benefited the fund as housing-related ABS have been the top-performing subsectors, delivering excess returns above those of the other spread sectors for the period.

We continue to find attractive relative valuation in the commercial mortgage market (CMBS), particularly in the highest quality AAA part of the capital structure, and remain overweight the sector. Commercial property cash flows, and thus, credit fundamentals of CMBS bonds, are improving. CMBS led all spread sectors in excess returns for the period and our overweight was a positive contributor to performance.

Notes to Financial Statements

A. Significant Accounting Policies

DWS Short Duration Fund (formerly Scudder Short Duration 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. The Trust is organized as a business trust under the laws of the state of Delaware. On August 21, 2006, DWS Short Duration Fund became a series of DWS Advisor Funds. Prior to August 21, 2006, DWS Short Duration Fund was a series of DWS Investments Trust.

The Fund currently has 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. Class S shares are no longer 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 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. Debt securities are valued by independent pricing services approved by the Trustees of the Fund. If the pricing services are unable to provide valuations, the securities are valued at the most recent bid quotation or evaluated price, as applicable, obtained from a broker-dealer. Such services may use various pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data, as well as broker quotes.

Equity securities are valued at the most recent sale price or official closing price reported on the exchange (US or foreign) or over-the-counter market on which the security is traded most extensively. Securities for which no sales are reported are valued at the calculated mean between the most recent bid and asked quotations on the relevant market or, if a mean cannot be determined, at the most recent bid quotation.

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

Securities and other assets for which market quotations are not readily available or for which the above valuation procedures are deemed not to reflect fair value are valued in a manner that is intended to reflect their fair value as determined in accordance with procedures approved by the Trustees.

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

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 an Exemptive Order 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.

When-Issued/Delayed Delivery Securities. The Fund may purchase securities with delivery or payment to occur at a later date beyond the normal settlement period. At the time the Fund enters into a commitment to purchase a security, the transaction is recorded and the value of the security is reflected in the net asset value. The price of such security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. No interest accrues to the Fund until payment takes place. At the time the Fund enters into this type of transaction it is required to segregate cash or other liquid assets at least equal to the amount of the commitment.

Certain risks may arise upon entering into when-issued or delayed delivery securities from the potential inability of counterparties to meet the terms of their contracts or if the issuer does not issue the securities due to political, economic, or other factors. Additionally, losses may arise due to changes in the value of the underlying securities.

Short Sales. The Fund may sell securities they do not own in an attempt to profit from an anticipated decline in their value or in order to hedge portfolio positions. The Fund borrows securities to complete the transaction. The Fund maintains collateral with the lender of the securities in the form of cash and/or liquid securities. At October 31, 2006, there were no securities sold short.

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 provisions were required.

At October 31, 2006, the Fund had a net tax basis capital loss carryforward of approximately $2,898,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until October 31, 2012 ($83,000), October 31, 2013 ($1,646,000) and October 31, 2014 ($1,169,000), the respective expiration dates, whichever occurs first.

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 is declared as a daily dividend and distributed to shareholders monthly. 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 relate primarily to 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 October 31, 2006, the Fund's components of distributable earnings (accumulated losses) on a tax-basis were as follows:

Undistributed ordinary income*	$ 202,191
Capital loss carryforwards	$ (2,898,000)
Net unrealized appreciation (depreciation) on investments	$ (809,778)

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

	Years Ended October 31,
	2006	2005
Distributions from ordinary income*	$ 5,895,407	$ 4,949,309

*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 15 days of buying them, either by purchase or exchange. This fee is assessed and retained by the Fund for the benefit of the remaining shareholders. The redemption fee is accounted for as an addition to paid-in capital.

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

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

Other. Investment transactions are accounted for on a trade date plus one basis for daily net asset value calculations. However, for financial reporting purposes, investment security transactions are reported on trade date. Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Realized gains and losses from investment transactions are recorded on an identified cost basis. All discounts and premiums are accreted/amortized for both tax and financial reporting purposes.

B. Purchases and Sales of Securities

During the year ended October 31, 2006, purchases and sales of investment securities (excluding short-term investments and US Treasury securities) aggregated $95,352,709 and $117,425,414, respectively. Purchases and sales of US Treasury securities aggregated $186,164,093 and $200,017,155, respectively.

The QP Trust does not pay its Advisor a management fee for the affiliated funds' investments in the QP Trust.

D. Expense Reductions

For the year ended October 31, 2006, the Advisor reimbursed the Fund $3,966 which represented a portion of the expected fee savings for the Advisor through June 30, 2006 related to the outsourcing by the Advisor of certain administrative services to an unaffiliated service provider.

F. Line of Credit

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.

G. Regulatory Matters and Litigation

Regulatory Settlements. On December 21, 2006, Deutsche Asset Management ("DeAM") settled proceedings with the Securities and Exchange Commission ("SEC") and the New York Attorney General on behalf of Deutsche Asset Management, Inc. ("DeAM, Inc.") and Deutsche Investment Management Americas Inc. ("DeIM"), the investment advisors to many of the DWS Scudder funds, regarding allegations of improper trading at DeAM and at the legacy Scudder and Kemper organizations prior to their acquisition by DeAM in April 2002. These regulators alleged that although the prospectuses for certain funds in the regulators' view indicated that the funds did not permit market timing, DeAM, Inc. and DeIM breached their fiduciary duty to those funds in that their efforts to limit trading activity in the funds were not effective at certain times. The regulators also alleged that DeAM, Inc. and DeIM breached their fiduciary duty to certain funds by entering into certain market timing arrangements with investors. These trading arrangements originated in businesses that existed prior to the currently constituted 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 these trading arrangements. Under the terms of the settlements, DeAM, Inc. and DeIM neither admit nor deny any wrongdoing.

The terms of the SEC settlement, which identified improper trading in the legacy Deutsche and Kemper mutual funds only, provide for payment of disgorgement in the amount of $17.2 million. The terms of the settlement with the New York Attorney General provide for payment of disgorgement in the amount of $102.3 million, which is inclusive of the amount payable under the SEC settlement, plus a civil penalty in the amount of $20 million. The total amount payable by DeAM, approximately $122.3 million, would be distributed to funds and/or shareholders of the affected funds in accordance with a distribution plan to be developed by a distribution consultant. 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.

Among the terms of the settled orders, DeAM is subject to certain undertakings regarding the conduct of its business in the future, including: formation of a Code of Ethics Oversight Committee to oversee all matters relating to issues arising under the advisors' Code of Ethics; establishment of an Internal Compliance Controls Committee having overall compliance oversight responsibility of the advisors; engagement of an Independent Compliance Consultant to conduct a comprehensive review of the advisors' supervisory compliance and other policies and procedures designed to prevent and detect breaches of fiduciary duty, breaches of the Code of Ethics and federal securities law violations by the advisors and their employees; and commencing in 2008, the advisors shall undergo a compliance review by an independent third party.

In addition, DeAM is subject to certain further undertakings relating to the governance of the mutual funds, including that: at least 75% of the members of the Boards of Trustees/Directors overseeing the DWS Funds continue to be independent of DeAM; the Chairmen of the DWS Funds' Boards of Trustees/Directors continue to be independent of DeAM; DeAM maintain existing management fee reductions for certain funds for a period of five years and not increase management fees for certain funds during this period; the funds retain a senior officer (or independent consultants) responsible for assisting in the review of fee arrangements and monitoring compliance by the funds and the investment advisors with securities laws, fiduciary duties, codes of ethics and other compliance policies, the expense of which shall be borne by DeAM; and periodic account statements, fund prospectuses and the mutual funds' web site contain additional disclosure and/or tools that assist investors in understanding the fees and costs associated with an investment in the funds and the impact of fees and expenses on fund returns.

DeAM also continues to discuss a settlement with the Illinois Secretary of State regarding market timing matters. As previously disclosed, DeAM expects a settlement with the Illinois Secretary of State to provide for investor education contributions totaling approximately $4 million and a payment in the amount of $2 million to the Securities Audit and Enforcement Fund.

On September 28, 2006, the 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 distributed to the funds was approximately $17.8 million and was paid 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. Based on the prescribed settlement order, the Fund was not entitled to a portion of the settlement.

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.

Private Litigation Matters. The matters alleged in the regulatory settlements described above also serve as the general basis of a number of private class action lawsuits involving the DWS funds. These lawsuits name 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 similar allegations.

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.

Report of Independent Registered Public Accounting Firm

To the Trustees of DWS Advisor Funds and Shareholders of DWS Short Duration 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 Short Duration Fund (formerly Scudder Short Duration Fund) (the "Fund") at October 31, 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.

Investment Management Agreement Approval

The Fund's Trustees approved the continuation of the Fund's current investment management agreement with DeAM, Inc. and the current sub-advisory agreement between DeAM, Inc. and Aberdeen Asset Management Inc. ("AAMI") in September 2006. The Fund's current investment management 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 agreements, shareholders should know that:

At present time, all but one of your Fund's Trustees are independent of DeAM, Inc. 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 management 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 management agreement and sub-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.

The sub-advisory fee paid to AAMI is paid by DeAM, Inc. out of its fee and not directly by the Fund.

DeAM, Inc. 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, Inc. 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, Inc.'s and AAMI'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 management agreement and sub-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, Inc. by similar funds and institutional accounts advised by DeAM, Inc. (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 higher than the median (3rd 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, Inc., 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, Inc. 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 (2nd 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, Inc. 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, Inc., 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 2nd quartile, 1st quartile and 2nd quartile, respectively, of the applicable Lipper universe. The Board also observed that the Fund has outperformed its benchmark in the one-, three- and five-year periods ended June 30, 2006. The Board recognized that DeAM, Inc. 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, Inc. and AAMI. The Board considered extensive information regarding DeAM, Inc., including DeAM, Inc.'s and AAMI'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 management agreement and sub-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, Inc. and AAMI have benefited and should continue to benefit the Fund and its shareholders.

The costs of the services to, and profits realized by, DeAM, Inc. and its affiliates from their relationships with the Fund. The Board reviewed information concerning the costs incurred and profits realized by DeAM, Inc. during 2005 from providing investment management services to the Fund (and, separately, to the entire DWS Scudder fund complex), and reviewed with DeAM, Inc. the cost allocation methodology used to determine DeAM, Inc.'s profitability. In analyzing DeAM, Inc.'s costs and profits, the Board also reviewed the fees paid to and services provided by DeAM, Inc. 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, Inc. and its affiliates as a result of DeAM, Inc.'s relationship with the Fund. As part of this review, the Board considered information provided by an independent accounting firm engaged to review DeAM, Inc.'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, Inc. 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, Inc. and its affiliates) was lower than the overall profitability levels of many comparable firms for which such data was available.

The practices of DeAM, Inc. and AAMI 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, Inc. or AAMI, 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, Inc. and its affiliates) research services from third parties that are generally useful to DeAM, Inc. 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, Inc.'s commitment to and record of compliance, including its written compliance policies and procedures. In this regard, the Board considered DeAM, Inc.'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, Inc. to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of DeAM, Inc.'s chief compliance officer, who reports to the Board; (ii) the large number of compliance personnel who report to DeAM, Inc.'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 management agreement and sub-advisory agreement, and concluded that the continuation of such agreements was in the best interests of the Fund's shareholders.

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

ITEM 2. CODE OF ETHICS.

As of the end of the period, October 31, 2006, DWS Short Duration 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” 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.

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:

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

         o        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;

         o        promote   compliance   with   applicable   laws,   rules   and
                  regulations;

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

         o        establish accountability for adherence to the Officer Code.

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

- --------

(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.


                                       3


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


                                       4


         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).

         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.

pre-approval by the Fund's audit committee.


                                       5


         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:

         o        Unethical or dishonest behavior

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

         o        Failure to report violations of the Officer Code

         o        Known or obvious  deviations from Applicable Laws

         o        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.

         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


- --------

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

(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.


                                       7


         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:

         (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.



                                       8


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.
