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. Additionally, investing in foreign securities presents certain unique risks not associated with domestic investments, such as currency fluctuation, political and economic changes, and market risks. Derivatives could produce disproportionate losses due to a variety of factors, including the unwillingness or inability of the counterparty to meet its obligations or unexpected price or interest-rate movements. 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 April 30, 2007

Classes A, B, C, R 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 4.5%. 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. Class R and Institutional Class are not subject to sales charges.

The total annual fund operating expense ratios, gross of any fee waivers or expense reimbursements, as stated in the fee table of the prospectus dated March 1, 2007 are 1.04%, 1.76%, 1.68%, 1.12% and .62% for Class A, Class B, Class C, Class R and Institutional Class shares, respectively. Please see the Information About Your Fund's Expenses, the Financial Highlights and Notes to the Financial Statements (Note C, Related Parties) sections of this report for gross and net expense related disclosure for the period ended April 30, 2007.

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

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

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

On July 10, 2006, the fund was reorganized from DWS Core Fixed Income Fund, a series of DWS Investments Trust (the "Predecessor Fund"), into DWS Core Fixed Income 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 July 10, 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 June 28, 2002 and Class R shares on October 1, 2003 are derived from the historical performance of Institutional Class shares of DWS Core Fixed Income 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 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 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 (November 1, 2006 to April 30, 2007).

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.

Portfolio Management Review

In the following interview, Gary Bartlett, senior portfolio manager for DWS Core Fixed Income Fund, discusses the recent market environment and strategy in managing the fund during its most recent semiannual period ended April 30, 2007.

Q: How did the bond market perform?

A: The US Federal Reserve Board (the "Fed") has left the fed funds target rate unchanged at its last seven meetings, including five during the six-month period, as Fed Chairman Bernanke has indicated that future Fed action will be "data dependent." Economic data has been mixed. For its part, the US Treasury market has reacted in stride with the headlines — selling off with signals of a resilient economy or inflationary pressures and rallying as part of a flight to quality or with indications of a weakening economy, most notably due to concern over a spillover from the housing slowdown. For the six-month period ending April 30, 2007, US Treasury yields initially climbed before retreating — and leveling off — late in the period. The benchmark 10-year US Treasury, despite trading in a range of 47 basis points, ended the period yielding 4.62%, up a mere 2 basis points from 4.60% six months earlier. (100 basis points equals one percentage point.) The US Treasury yield curve steepened as both the 2-year and 5-year US Treasury yields declined by 10 bps and 5 bps to end at 4.60% and 4.51%, respectively.¹ Indeed the curve, which began the period inverted between two and ten years, ended the period with a slightly positive slope.

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.

For the six months, the Lehman Brothers US Aggregate Bond Index returned 2.64%, essentially returning its coupon rate for the period.² At the beginning of the six-month period, the trend of rising rates was accompanied by tightening credit spreads, only for the pattern to reverse later in the period. Within the Lehman Brothers US Aggregate Bond Index, US Treasuries returned 2.19% for the period and all spread sectors posted positive nominal returns, with most delivering positive excess returns relative to comparable duration treasuries.³ Corporates led the way (2.95%) followed by residential mortgage-backed securities (MBS at 2.78%), agencies (2.45%) and asset-back securities (ABS at 2.44%). Only commercial mortgage-backed securities (CMBS at 2.40%) slightly lagged relative to duration-equivalent treasuries.

² The Lehman Brothers US Aggregate Bond Index is an unmanaged market value-weighted measure of treasury issues, agency issues, corporate bond issues and mortgage securities. Index returns assume reinvestment of dividends and, unlike fund returns, do not reflect any fees or expenses. It is not possible to invest directly into an index.
³ Spread sectors are non-Treasury bond sectors of the fixed-income market.

Q: How did the fund perform?

A: DWS Core Fixed Income Fund Class A shares returned 2.50% for the period ended April 30, 2007. (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 5 through 11 for the performance of other share classes and more complete performance information.) This compares with 2.53% for the average fund in the Lipper Intermediate Investment Grade Debt Funds category and 2.64% for the Lehman Brothers US Aggregate Bond Index, the fund's benchmark.⁴

⁴ The Lipper Intermediate Investment Grade Debt Funds category consists of funds that invest at least 65% of assets in investment-grade debt issues (rated in the top four grades) with dollar-weighted average maturities of five to 10 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 dividends. It is not possible to invest directly into a Lipper category.

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

A: Corporates bested all sectors in excess returns and credit spreads were essentially unchanged for the period. But this headline masks a more revealing story. Performance was led by lower-quality issues and subsectors as both industrials and utilities benefited from credit spread tightening. Despite weakness in the subprime mortgage sector and leveraged buyout (LBO) concerns, which drove spreads in financials wider, the sector still managed positive returns. Low-quality credit spread tightening in the face of balance sheet releveraging is, in our view, symptomatic of a global reach for yield precipitated by excess dollar liquidity, rather than a reflection of investors' views on fundamentals. The fund's corporate weighting, and specifically our weighting to BBB-rated corporates, has continued to come down as a reflection of this.⁵ Notwithstanding, we remain overweight BBBs, which aided performance during the period.⁶ The industrial sector, specifically telecom and media cable, was another strong performer during the period. Investments in these sectors contributed to performance resulting from our overweight and security selection. Additionally, holdings in utilities aided performance, although our investment in Commonwealth Edison hurt performance late in the period, as rating agencies reacted to concerns about a possible freezing of consumer electric rates in Illinois by downgrading its unsecured debt to below investment grade.

⁵ Credit quality is a measure of a bond issuer's ability to repay interest and principal in a timely manner. Rating agencies assign letter designations such as AAA, AA, and so forth. The lower the rating, the higher the probability of default.
⁶ "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.

The fund's mortgage portfolio, structurally underweight volatility exposure, dampened results early in the period, but overall contributed positively to performance for the six months as interest rate volatility (finally) spiked from its historically depressed levels. Additionally, the fund's significant exposure to prime quality hybrid adjustable rate mortgages (ARMs) widened during March (in sympathy with subprime hybrid ARM headlines), but remain tighter than beginning of year levels. Mortgage index performance, relative to duration-equivalent treasuries, lagged only corporates for the period, and the portfolio remains slightly overweight in mortgage spread duration.

Asset backed securities (ABS) were negatively impacted by wider interest rate swap spreads (the trading benchmark for the sector) and by underperformance in home equity loan securities (subprime mortgages). While the fund's raw percentage overweight in this subsector appears significant, nearly the entirety of the fund's home equity position is in very short-term, AAA-rated bonds that have experienced minimal impact from the worsening performance of subprime mortgages generally. Further signs of a stabilization in the subprime market helped home equity loan ABS to rebound in April and generally the fund's investments in ABS were a neutral factor for performance. We have pared the fund's investments in ABS, but remain overweight with holdings concentrated in short duration home equity securities where we believe the total rate of return advantage relative to US treasuries remains compelling.

Commercial mortgages underperformed treasuries (-2 bps) during the period, but our significant intra-quarter sales just prior to the spread widening in both swaps and commercial mortgage backed securities (CMBS) helped the fund performance relative to the benchmark. We are currently underweight the sector, but have begun adding back to the fund's positions at or near the recent wider spread levels.

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

Notes to Financial Statements (Unaudited)

A. Significant Accounting Policies

DWS Core Fixed Income 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 management investment company. The Trust is organized as a business trust under the laws of the state of Delaware.

The Fund offers multiple classes of shares which provide investors with different purchase options. Class A shares are offered to investors subject to an initial sales charge. Class B shares are offered 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. Class R shares are only available to participants in certain retirement plans and are offered to investors without an initial sales charge or contingent deferred sales charge. Institutional Class shares are offered to a limited group of investors, are not subject to initial or contingent deferred sales charges and have lower ongoing expenses than other classes. Class S shares are not subject to initial or contingent deferred sales charges and are generally not available to new investors except under certain circumstances.

Investment income, realized and unrealized gains and losses, and certain fund-level expenses and expense reductions, if any, are borne pro rata on the basis of relative net assets by the holders of all classes of shares, except that each class bears certain expenses unique to that class such as services to shareholders and certain other class-specific expenses. 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, the Financial Accounting Standards Board ("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 April 30, 2007, 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.

Mortgage Dollar Rolls. The Fund may enter into mortgage dollar rolls in which the Fund sells to a bank or broker/dealer (the "counterparty") mortgage-backed securities for delivery in the current month and simultaneously contracts to repurchase similar, but not identical, securities on a fixed date. The counterparty receives all principal and interest payments, including prepayments, made on the security while it is the holder. The Fund receives compensation as consideration for entering into the commitment to repurchase. The compensation is paid in the form of a lower price for the security upon its repurchase, or alternatively, a fee. Mortgage dollar rolls may be renewed with a new sale and repurchase price and a cash settlement made at each renewal without physical delivery of the securities subject to the contract.

Certain risks may arise upon entering into mortgage dollar rolls from the potential inability of counterparties to meet the terms of their commitments. Additionally, the value of such securities may change adversely before the Fund is able to repurchase them. There can be no assurance that the Fund's use of the cash that it receives from a mortgage dollar roll will provide a return that exceeds its costs.

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 $11,645,000, which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until October 31,2014, the respective expiration date, which may be subject to certain limitations under sections 382-383 of the Internal Revenue Code.

In July 2006, FASB issued Interpretation No. 48 ("FIN 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. On December 22, 2006, the SEC indicated that they would not object if a Fund implements FIN 48 in the first required financial statement reporting period for its fiscal year 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 primarily 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.

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

Redemption Fees. The Fund imposes a redemption fee of 2% of the total redemption amount on 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.

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 six months ended April 30, 2007, purchases and sales of investment securities (excluding short-term investments, US Treasury Obligations and mortgage dollar roll transactions) aggregated $467,590,298 and $534,984,056, respectively. Purchases and sales of US Treasury obligations aggregated $979,823,242 and $823,154,176, respectively. Purchases and sales of mortgage dollar rolls aggregated $66,968,708 and $59,090,909, respectively.

For the period from November 1, 2006 through September 30, 2007, the Advisor has contractually agreed to waive all or a portion of its management fee and reimburse or pay certain operating expenses of the Fund (excluding certain expenses such as extraordinary expenses, taxes, brokerage, interest, proxy and organizational and offering expenses) to the extent necessary to maintain the operating expenses of each class as follows:

Class A	.99%
Class B	1.74%
Class C	1.74%
Class R	1.24%
Class S	.74%

In addition for the period from November 1, 2006 through April 30, 2007, the Advisor has agreed to voluntarily waive all or a portion of its management fee and reimburse or pay certain operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage, interest, proxy and organizational and offering expenses) to the extent necessary to maintain the operating expenses of each class as follows:

Class A	.80%
Class B	1.55%
Class C	1.55%
Class R	1.05%
Class S	.55%
Institutional Class	.55%

Accordingly, for the six months ended April 30, 2007, the Advisor waived a portion of its advisory fee pursuant to the Investment Management Agreement aggregating $58,387 and the amount charged aggregated $2,867,383 which was equivalent to an annualized effective rate of 0.39% of the Fund's average daily net assets.

Furthermore, for the six months ended April 30, 2007, the Advisor reimbursed the Fund $27,149 of services to shareholders from non-affiliated entities for Class S shares.

Administration Fee. Pursuant to the Administrative Services Agreement with the DIMA, the Advisor provides most administrative services to the Fund. For all services provided under the Administrative Services Agreement, the Fund pays the Advisor an annual fee ("Administration Fee") of 0.10% of the Fund's average daily net assets, computed and accrued daily and payable monthly. For the six months ended April 30, 2007, the Advisor received an Administration Fee of $731,546, of which $125,650 is unpaid.

Service Provider Fees. DWS Scudder Investments Service Company ("DWS-SISC"), an affiliate of the Advisor, is the Fund's transfer agent, dividend-paying agent and shareholder service agent for Class A, B, C, R and Institutional Class shares of the Fund. DWS Scudder Service Corporation ("DWS-SSC"), an affiliate of the Advisor, was the Fund's transfer agent, dividend-paying agent and shareholder service agent for Class S shares of the Fund. Effective April 1, 2007, DWS-SSC merged with DWS-SISC. The Board of the Fund approved a new transfer agency agreement between the Fund and DWS-SISC. The new transfer agency agreement is identical in substance to the previous transfer agency agreement for the Fund, except for the named transfer agent. Pursuant to a sub-transfer agency agreement among DWS-SISC, DWS-SSC (through March 31, 2007) and DST Systems, Inc. ("DST"), DWS-SISC and DWS-SSC compensate DST out of the shareholder servicing fee they receive from the Fund. For the six months ended April 30, 2007, the amounts charged to the Fund by DWS-SISC and DWS-SSC (through March 31, 2007) were as follows:

Services to Shareholders	Total Aggregated	Waived	Unpaid at April 30, 2007
Class A	$ 520,304	$ 520,304	$ —

Institutional Class	79,680	79,680	—
	$ 747,591	$ 747,232	$ 314

Distribution Service Agreement. Under the Distribution Service 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 0.75% of average daily net assets of the Class B and C shares, 0.25% of average daily net assets for Class R shares. Pursuant to the agreement, DWS-SDI enters into related selling group agreements with various firms at various rates for sales of Class A, B, C and R shares. For the six months ended April 30, 2007, the Distribution Fee was as follows:

Distribution Fee	Total Aggregated	Unpaid at April 30, 2007
Class B	$ 126,901	$ 21,335
Class C	215,932	38,024
Class R	7,151	1,786
	$ 349,984	$ 61,145

In addition, DWS-SDI provides information and administrative services for a fee ("Service Fee") to the shareholders of Class B, Class C and Class R at an annual 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 six months ended April 30, 2007, the Service Fee was as follows:

Service Fee	Total Aggregated	Waived	Unpaid at April 30, 2007	Annualized Effective Rate
Class A	$ 787,045	66,898	$ 250,376	.22%
Class B	41,763	4,293	13,251	.22%
Class C	70,340	3,575	23,412	.23%
Class R	6,823	—	2,733	.24%
	$ 905,971	$ 74,766	$ 289,772

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 six months ended April 30, 2007, aggregated $14,397.

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 six months ended April 30, 2007, the CDSC for Class B and C shares aggregated $40,964 and $5,790, respectively. A deferred sales charge of up to 0.85% is assessed on certain redemptions of Class A shares. For the six months ended April 30, 2007, DWS-SDI received $23 for Class A shares.

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

Typesetting and Filing Service Fees. Under an agreement with DIMA, DIMA is compensated for providing typesetting and certain regulatory filing services to the Fund. For the six months ended April 30, 2007, the amount charged to the Fund by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $25,342, of which $9,256 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 Chairperson of the Board and the Chairperson 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.

D. Investing in High Yield Securities

Investing in high yield securities may involve greater risks and considerations not typically associated with investing in US Government bonds and other high quality fixed-income securities. These securities are non-investment grade securities, often referred to as "junk bonds." Economic downturns may disrupt the high yield market and impair the ability of issuers to repay principal and interest. Also, an increase in interest rates would likely have an adverse impact on the value of such obligations. Moreover, high yield securities may be less liquid due to the extent that there is no established retail secondary market and because of a decline in the value of such securities.

E. Fee Reductions

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 custodian expenses. During the six months ended April 30, 2007, the Fund's custodian fees were reduced by $2,117, for custodian credits earned.

F. Line of Credit

The Fund and 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 0.35 percent. The Fund may borrow up to a maximum of 10 percent of its net assets under the agreement.

H. 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. ("DAMI") and Deutsche Investment Management Americas Inc. ("DIMA"), the investment advisors to many of the DWS Scudder funds, regarding allegations of improper trading of fund shares 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, DAMI and DIMA 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 DAMI and DIMA 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, DAMI and DIMA neither admitted nor denied 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 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 has also settled proceedings with the Illinois Secretary of State regarding market timing matters. The terms of the Illinois settlement 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. ("DIMA"), Deutsche Asset Management, Inc. ("DAMI") 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 DIMA and DAMI 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 DIMA, DAMI and SDI neither admitted nor denied any of the regulators' findings, DIMA, DAMI 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, DIMA, DAMI 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.

Investment Management Agreement Approval

In December 2006, the Board approved an amended and restated investment management agreement with DIMA in connection with the merger of DAMI into DIMA. In determining to approve this agreement, the Board considered Deutsche Bank's representations that this change was administrative in nature, and would not involve any change in operations or services provided to the fund, or to the personnel involved with providing such services. The Board also considered that the terms of the agreement with DIMA were substantially identical to the terms of the fund's prior agreement with DAMI. A discussion of factors considered by the Board in determining to approve the continuation of the fund's prior investment management agreement with DAMI in September 2006 in connection with the Board's annual review of the fund's contractual arrangements is included in the fund's report for the period ended October 31, 2006.
