This report must be preceded or accompanied by a prospectus. To obtain a summary prospectus, if available, or prospectus for any of our funds, visit www.dws-investments.com. We advise you to consider the fund's objectives, risks, charges and expenses carefully before investing. The summary prospectus and prospectus contain this and other important information about the fund. Please read the prospectus carefully before you invest.
 
An investment in this fund is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC) or by any other government agency. Although the fund seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the fund. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Advisor to enter into support agreements or take other actions to maintain the fund's $1.00 share price. The credit quality of the fund's holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the fund's share price. The fund's share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. The actions of a few large investors in one class of shares of the fund may have a significant adverse effect on the share prices of all classes of shares of the fund. See the prospectus for specific details regarding the fund's risk profile.

Portfolio Management Review
 
Market Overview and Fund Performance
 
All performance information below is historical and does not guarantee future results. Investment return and principal fluctuate, so your shares may be worth more or less when redeemed. Current performance may differ from performance data shown. Please visit www.dws-investments.com for the fund's most recent month-end performance. The 7-day current yield refers to the income paid by the fund over a 7-day period expressed as an annual percentage rate of the fund's shares outstanding. Yields fluctuate and are not guaranteed.
 
Over the fund's most recent 12-month period, money markets continued to respond to alternating degrees of perceived risk in the global financial markets. Short-term rates rose or fell slightly in response to the current state of the European sovereign debt crisis.
 
The fund seeks maximum current income that is exempt from federal and state of California income taxes to the extent consistent with stability of capital.
 
During the first quarter of 2012, efforts by the European Central Bank (ECB) to ensure adequate funding access at low rates for the Continent's major banks momentarily reassured investors and led to a rally in global financial markets. However, in May we saw another dramatic "flight to quality," as worries concerning Greece's upcoming elections and continuingly worsening conditions for Spanish and Italian banks led global and domestic investors to abandon risk assets. Toward the close of the period, any negative economic data was overshadowed by the optimistic tone set by substantial Central Bank actions. First, the ECB lowered its interest rate for bank reserves. Then, the head of the ECB, Mario Draghi, stated that the Central Bank would do "whatever is needed" to preserve the euro. In addition, the fact that Germany has hinted that it may be willing to participate in a European quantitative easing program provided substantial encouragement to investors. Lastly, market watchers welcomed an announcement by the U.S. Federal Reserve Board (the Fed) that it would embark on a third round of quantitative easing, and that it intended to maintain short-term interest rates near zero through mid-2015.
 
 
Positive Contributors to Fund Performance
 
During its fiscal year ended September 30, 2012, the fund's portfolio registered favorable performance and achieved its stated objectives of providing maximum California tax-exempt income while maintaining stability of principal.
 
"As managers, we will continue to be cautious, relying substantially on floating-rate securities for yield and flexibility."
 
As the state of California struggled to fully revive its economy during the past 12 months, we sought to balance higher yield with top quality by maintaining a strong position in floating-rate securities, taking advantage of comparatively higher floating-rate interest coupons. The interest rate of floating-rate securities adjusts periodically based on indices such as the Securities Industry and Financial Markets Association Index of Variable Rate Demand Notes. Because the interest rates of these instruments adjust as market conditions change, they provide flexibility in an uncertain interest rate environment. As we saw opportunities along the yield curve, we also purchased attractively valued securities with slightly longer maturities in order to boost the fund's yield and total return.
 
 
Negative Contributors to Fund Performance
 
Preferring a cautious approach at a time of market uncertainty, we tilted the fund toward securities that tended to have higher quality and hence lower yields than issues carrying more risk. While this strategy cost the fund some yield, we believe that it represented a prudent approach to preserving principal.
 
Fund Results (as of September 30, 2012)
 
Performance is historical and does not guarantee future results. Current performance may be lower or higher than the performance data quoted.
 
An investment in a money market fund is not insured or guaranteed by the FDIC or any other government agency. Although money market funds seek to preserve the value of your investment at $1.00 per share, this share price isn't guaranteed and you could lose money by investing in money market funds. The share price of money market funds can fall below the $1.00 share price. You should not rely on or expect the Advisor to enter into support agreements or take other actions to maintain the fund's $1.00 share price. The credit quality of the fund's holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the fund's share price. The fund's share price can also be negatively affected during periods of high redemption pressures and/or illiquid markets. The actions of a few large investors in one class of shares of a fund may have a significant adverse effect on the share prices of all classes of shares of that fund. See the prospectus for specific details regarding the fund's risk profile.

Yields are historical, will fluctuate, and do not guarantee future performance. The 7-day current yield refers to the income paid by the fund over a 7-day period expressed as an annual percentage rate of the fund's shares outstanding. For the most current yield information, visit our Web site at www.dws-investments.com.
 
* The equivalent taxable yield allows you to compare with the performance of taxable money market funds. It is based on the fund's yield and an approximate combined federal and state of California marginal income tax rate of 41.70%. Income may be subject to local taxes, and for some investors, the alternative minimum tax.
 
Outlook and Positioning
 
We believe that California's officials are working hard to make necessary adjustments and position the state towards further recovery. We think that the state's economy will stabilize over the coming months and gradually improve over the next two years. To accomplish this, it appears to us that some state and city pension obligations will need to be restructured in order to aid budget-balancing efforts going forward. As managers, we will continue to be cautious, relying substantially on floating-rate securities for yield and flexibility. We will also look for opportunities in two-to-three-month California tax-free obligations in order to pick up incremental yield.
 
Our intent is to maintain a highly liquid portfolio with a short average maturity over the coming months. We continue to insist upon the highest credit quality within the fund, and plan to maintain our conservative investment strategies and standards.

Fair Value Measurements
 
Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Securities held by the Fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.
 
The following is a summary of the inputs used as of September 30, 2012 in valuing the Fund's investments. For information on the Fund's policy regarding the valuation of investments, please refer to the Security Valuation section of Note 1 in the accompanying Notes to Financial Statements.

Notes to Financial Statements
 
1. Organization and Significant Accounting Policies
 
Tax-Exempt California Money Market Fund (the "Fund") is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end, diversified management investment company organized as a Massachusetts business trust. The Fund may be affected by economic and political developments in the state of California.
 
The Fund offers two classes of shares to investors: Tax-Exempt California Money Market Fund — Premier Shares ("Premier Shares") and Tax-Exempt California Money Market Fund — Institutional Shares ("Institutional Shares").
 
Investment income, realized and unrealized gains and losses, and certain fund-level expenses and expense reductions, if any, were borne pro rata on the basis of relative net assets by the holders of all classes of shares, except that each class bears certain expenses unique to that class such as distribution fees, 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. Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
 
The Fund values all securities utilizing the amortized cost method permitted in accordance with Rule 2a-7 under the 1940 Act and certain conditions therein. Under this method, which does not take into account unrealized capital gains or losses on securities, an instrument is initially valued at its cost and thereafter assumes a constant accretion/amortization rate to maturity of any discount or premium. Securities held by the Fund are reflected as Level 2 because the securities are valued at amortized cost (which approximates fair value) and, accordingly, the inputs used to determine value are not quoted prices in an active market.
 
Disclosure about the classification of fair value measurements is included in a table following the Fund's Investment Portfolio.
 
New Accounting Pronouncement. In December 2011, Accounting Standards Update 2011-11 (ASU 2011-11), Disclosures about Offsetting Assets and Liabilities, was issued and is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. ASU 2011-11 is intended to enhance disclosure requirements on the offsetting of financial assets and liabilities. Management is currently evaluating the application of ASU 2011-11 and its impact, if any, on the Fund's financial statements.
 
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 tax-exempt income and capital gains to its shareholders.
 
Under the Regulated Investment Company Modernization Act of 2010, net capital losses may be carried forward indefinitely, and their character is retained as short-term and/or long-term. Previously, net capital losses were carried forward for eight years and treated as short-term losses. As a transition rule, the Act requires that post-enactment net capital losses be used before pre-enactment net capital losses.
 
The Fund has reviewed the tax positions for the open tax years as of September 30, 2012 and has determined that no provision for income tax is required in the Fund's financial statements. The Fund's federal tax returns for the prior three fiscal years remain open subject to examination by the Internal Revenue Service.
 
Distribution of Income and Gains. Net investment income of the Fund is declared as a daily dividend and is distributed to shareholders monthly. The Fund may take into account capital gains and losses in its daily dividend declarations. The Fund may also make additional distributions for tax purposes if necessary.
 
Permanent book and tax basis differences relating to shareholder distributions will result in reclassifications to paid in capital. Temporary book and tax basis differences will reverse in a subsequent period. There were no significant book-to-tax differences for the Fund.
 
At September 30, 2012, the Fund's components of distributable earnings (accumulated losses) on a tax basis are as follows:
Undistributed ordinary income *
  $ 31,125  
Undistributed tax-exempt income
  $ 9,588  
 
In addition, the tax character of distributions paid to shareholders by the Fund is summarized as follows:

2011
 
Distributions from tax-exempt income
  $ 15,948     $ 110,959  
 
* For tax purposes, short-term capital gain distributions are considered ordinary income distributions.
 
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 trade date. Interest income is recorded on the accrual basis. 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.
 
2. Related Parties
 
Management Agreement . Under the Investment Management Agreement with Deutsche Investment Management Americas Inc. ("DIMA" or the "Advisor"), an indirect, wholly owned subsidiary of Deutsche Bank AG, the Advisor directs the investments of the Fund in accordance with its investment objectives, policies and restrictions. The Advisor determines the securities, instruments and other contracts relating to investments to be purchased, sold or entered into by the Fund.
 
Under the Investment Management Agreement with the Advisor, the Fund pays a monthly management fee based on the Fund's average daily net assets, computed and accrued daily and payable monthly at the following annual rates:
First $500 million of the Fund's average daily net assets
    .120 %
Next $500 million of such net assets
    .100 %
Next $1 billion of such net assets
    .075 %
Next $1 billion of such net assets
    .060 %
Over $3 billion of such net assets
    .050 %
 
For the period from October 1, 2011 through September 30, 2013 the Advisor has contractually agreed to waive its fees and/or reimburse certain operating expenses of the Fund to the extent necessary to maintain the operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage and interest) of the Institutional Shares at 0.25%.
 
In addition, the Advisor has agreed to voluntarily waive additional expenses. The voluntary waiver may be changed or terminated at any time without notice. Under this arrangement, the Advisor waived certain expenses of the Fund.
 
Accordingly, for the year ended September 30, 2012, the fee pursuant to the Investment Management Agreement aggregated $142,449, all of which was waived, resulting in an annual effective rate of 0.00% of the Fund's average daily net assets.
 
Administration Fee. Pursuant to an Administrative Services Agreement, DIMA 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 year ended September 30, 2012, the Administration Fee was $118,707, of which $56,615 was waived.
 
Service Provider Fees. DWS Investments Service Company ("DISC"), an affiliate of the Advisor, is the transfer agent, dividend-paying agent and shareholder service agent for the Fund. Pursuant to a sub-transfer agency agreement among DISC and DST Systems, Inc. ("DST"), DISC has delegated certain transfer agent, dividend-paying agent and shareholder service agent functions to DST. DISC compensates DST out of the shareholder servicing fee it receives from the Fund. For the year ended September 30, 2012, the amounts charged to the Fund by DISC were as follows:

    25,497       25,497        
    $ 39,264     $ 38,876     $ 385  
 
Distribution Fee. Under the Fund's Premier Shares 12b-1 Plan, DWS Investments Distributors, Inc. ("DIDI"), an affiliate of the Advisor, receives a fee ("Distribution Fee") of 0.33% of average daily net assets of the Premier Shares. In accordance with the Fund's Underwriting and Distribution Services Agreement, DIDI enters into related selling group agreements with various firms at various rates for sales of the Premier Shares. For the year ended September 30, 2012, the Distribution Fee for the Premier Shares aggregated $17,795, all of which was waived.
 
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 year ended September 30, 2012, the amount charged to the Fund by DIMA included in the Statement of Operations under "reports to shareholders" aggregated $15,132, of which $4,860 is unpaid.
 
Trustees' Fees and Expenses. The Fund paid retainer fees to each Trustee not affiliated with the Advisor, plus specified amounts to the Board Chairperson and to each committee Chairperson.
 
3. Line of Credit
 
The Fund and other affiliated funds (the "Participants") share in a $375 million revolving credit facility provided by a syndication of banks. The Fund may borrow for temporary or emergency purposes, including the meeting of redemption requests that otherwise might require the untimely disposition of securities. The Participants are charged an annual commitment fee, which is allocated based on net assets, among each of the Participants. Interest is calculated at a rate per annum equal to the sum of the Federal Funds Rate plus 1.25 percent plus if LIBOR exceeds the Federal Funds Rate the amount of such excess. The Fund may borrow up to a maximum of 33 percent of its net assets under the agreement. The Fund had no outstanding loans at September 30, 2012.

Report of Independent Registered Public Accounting Firm
 
To the Trustees and Shareholders of Tax-Exempt California Money Market Fund:
 
We have audited the accompanying statement of assets and liabilities of Tax-Exempt California Money Market Fund (the "Fund"), including the investment portfolio, as of September 30, 2012, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein. These financial statements and financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. We were not engaged to perform an audit of the Fund's internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of September 30, 2012 by correspondence with the custodian. We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Tax-Exempt California Money Market Fund at September 30, 2012, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the periods indicated therein, in conformity with U.S. generally accepted accounting principles.

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 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 (April 1, 2012 to September 30, 2012).
 
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.

Investment Management Agreement Approval
 
The Board of Trustees approved the renewal of Tax-Exempt California Money Market Fund's investment management agreement (the "Agreement") with Deutsche Investment Management Americas Inc. ("DWS") in September 2012.
 
In terms of the process that the Board followed prior to approving the Agreement, shareholders should know that:
 
In September 2012, all of the Fund's Trustees were independent of DWS and its affiliates.
 
The Trustees met frequently during the past year to discuss fund matters and dedicated a substantial amount of time to contract review matters. Over the course of several months, the Board's Contract Committee, in coordination with the Board's Fixed Income and Quant Oversight Committee, reviewed comprehensive materials received from DWS, independent third parties and independent counsel. These materials included an analysis of the Fund's performance, fees and expenses, and profitability compiled by the Fund's independent fee consultant. The Board also received extensive information throughout the year regarding performance of the Fund.
 
The Independent Trustees regularly meet privately with their independent counsel to discuss contract review and other matters. In addition, the Independent Trustees were also advised by the Fund's independent fee consultant in the course of their review of the Fund's contractual arrangements and considered a comprehensive report prepared by the independent fee consultant in connection with their deliberations (the "IFC Report").
 
In connection with reviewing the Agreement, the Board also reviewed the terms of the Fund's Rule 12b-1 plan, distribution agreement, administrative services agreement, transfer agency agreement and other material service agreements.
 
Based on its evaluation of the information provided, the Contract Committee presented its findings and recommendations to the Board. The Board then reviewed the Contract Committee's findings and recommendations.
 
In connection with the contract review process, the Contract Committee and the Board considered the factors discussed below, among others. The Board also considered that DWS and its predecessors have managed the Fund since its inception, and the Board believes that a long-term relationship with a capable, conscientious advisor is in the best interests of the Fund. The Board considered, generally, that shareholders chose to invest or remain invested in the Fund knowing that DWS managed the Fund, and that the Agreement was approved by the Fund's shareholders. DWS is part of Deutsche Bank, a major global banking institution that is engaged in a wide range of financial services. The Board believes that there are 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.
 
As part of the contract review process, the Board carefully considered the fees and expenses of each DWS fund overseen by the Board in light of the fund's performance. In many cases, this led to a negotiation with DWS of lower expense caps for the coming year than had previously been in place. As part of these negotiations, the Board indicated that it would consider relaxing these new lower caps in future years following sustained improvements in performance, among other considerations.
 
In June 2012, Deutsche Bank ("DB"), DWS's parent company, announced that DB's new management team had concluded the strategic review of its global asset management business announced in late 2011 by DB's prior management team, and would combine its Asset Management (of which DWS is a part) and Wealth Management divisions. Prior to approving the investment management agreements, the Independent Trustees were apprised of the expected management and structure of the new combined Asset & Wealth Management division ("AWM") and DWS. DB also advised the Independent Trustees that the U.S. asset management business is a critical and integral part of DB and AWM, and that DB would be reinvesting a significant portion of the substantial savings it expects to realize by combining its Asset Management and Wealth Management divisions into a combined AWM division, including enhancements to its investment capabilities. DB also confirmed its commitment to maintaining strong legal and compliance groups within the combined division.
 
While shareholders may focus primarily on fund performance and fees, the Fund's Board considers these and many other factors, including the quality and integrity of DWS's personnel and such other issues as back-office operations, fund valuations, and compliance policies and procedures.
 
Nature, Quality and Extent of Services. The Board considered the terms of the Agreement, including the scope of advisory services provided under the Agreement. The Board noted that, under the Agreement, DWS provides portfolio management services to the Fund and that, pursuant to a separate administrative services agreement, DWS provides administrative services to the Fund. The Board considered the experience and skills of senior management and investment personnel, the resources made available to such personnel, the ability of DWS to attract and retain high-quality personnel, and the organizational depth and stability of DWS. The Board reviewed the Fund's performance over short-term and long-term periods and compared those returns to various agreed-upon performance measures, including a peer universe compiled by the independent fee consultant using information supplied by iMoneyNet Inc. ("iMoneyNet"), an independent fund data service. The Board also noted that it has put into place a process of identifying "Focus Funds" (e.g., funds performing poorly relative to their benchmark or a peer universe compiled by an independent fund data service), and receives more frequent reporting and information from DWS regarding such funds, along with DWS's remedial plans to address underperformance. The Board believes this process is an effective manner of identifying and addressing underperforming funds. Based on the information provided, the Board noted that for the one- and three-year periods ended December 31, 2011, the Fund's gross performance (Premier Shares) was in the 1st quartile of the applicable iMoneyNet universe (the 1st quartile being the best performers and the 4th quartile being the worst performers).
 
Fees and Expenses. The Board considered the Fund's investment management fee schedule, operating expenses and total expense ratios, and comparative information provided by Lipper Inc. ("Lipper") and the independent fee consultant regarding investment management fee rates paid to other investment advisors by similar funds (1st quartile being the most favorable and 4th quartile being the least favorable). With respect to management fees paid to other investment advisors by similar funds, the Board noted that the contractual fee rates paid by the Fund, which include a 0.10% fee paid to DWS under the Fund's administrative services agreement, were lower than the median (1st quartile) of the applicable Lipper peer group (based on Lipper data provided as of December 31, 2011). Based on the Lipper data provided as of December 31, 2011, the Board noted that the Fund's total (net) operating expenses were lower than the median of the applicable Lipper expense universe for Premier Shares (1st quartile) and for Institutional Shares (1st quartile). The Board considered the Fund's management fee rate as compared to fees charged by DWS and certain of its affiliates for comparable mutual funds and considered differences in fund and fee structures between the DWS Funds. 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 noted the expense limitation agreed to by DWS. The Board also noted the significant voluntary fee waivers implemented by DWS to ensure that the Fund maintained a positive yield.
 
The information considered by the Board as part of its review of management fees included information regarding fees charged by DWS and its affiliates to similar institutional accounts and to similar funds offered primarily to European investors ("DWS Europe funds"), in each case as applicable. The Board observed that advisory fee rates for institutional accounts generally were lower than the management fees charged by similarly managed DWS U.S. mutual funds ("DWS Funds"), but also took note of the differences in services provided to DWS Funds as compared to institutional accounts. In the case of DWS Europe funds, the Board observed that fee rates for DWS Europe funds generally were higher than for similarly managed DWS Funds, but noted that differences in the types of services provided to DWS Funds relative to DWS Europe funds made it difficult to compare such fees.
 
On the basis of the information provided, the Board concluded that management fees were reasonable and appropriate in light of the nature, quality and extent of services provided by DWS.
 
Profitability. The Board reviewed detailed information regarding revenues received by DWS under the Agreement. The Board considered the estimated costs and pre-tax profits realized by DWS from advising the DWS Funds, as well as estimates of the pre-tax profits attributable to managing the Fund in particular. The Board also received information regarding the estimated enterprise-wide profitability of DWS and its affiliates with respect to all fund services in totality and by fund. The Board and the independent fee consultant reviewed DWS's methodology in allocating its costs to the management of the Fund. Based on the information provided, the Board concluded that the pre-tax profits realized by DWS in connection with the management of the Fund were not unreasonable. The Board also reviewed information regarding the profitability of certain similar investment management firms. The Board noted that while information regarding the profitability of such firms is limited (and in some cases is not necessarily prepared on a comparable basis), DWS and its affiliates' overall profitability with respect to the DWS fund complex (after taking into account distribution and other services provided to the funds by DWS and its affiliates) was lower than the overall profitability levels of many comparable firms for which such data was available.
 
Economies of Scale. The Board considered whether there are economies of scale with respect to the management of the Fund and whether the Fund benefits from any economies of scale. The Board noted that the Fund's management fee schedule includes fee breakpoints. The Board concluded that the Fund's fee schedule represents an appropriate sharing between the Fund and DWS of such economies of scale as may exist in the management of the Fund at current asset levels.
 
Other Benefits to DWS and Its Affiliates. The Board also considered the character and amount of other incidental benefits received by DWS and its affiliates, including any fees received by DWS for administrative services provided to the Fund and any fees received by an affiliate of DWS for distribution services. The Board also considered benefits to DWS related to brokerage and soft-dollar allocations, including allocating brokerage to pay for research generated by parties other than the executing broker dealers, which pertain primarily to funds investing in equity securities, along with the incidental public relations benefits to DWS related to DWS Funds advertising and cross-selling opportunities among DWS products and services. The Board concluded that management fees were reasonable in light of these fallout benefits.
 
Compliance. The Board considered the significant attention and resources dedicated by DWS to documenting and enhancing its compliance processes in recent years. The Board noted in particular (i) the experience and seniority of both DWS's chief compliance officer and the Fund's chief compliance officer; (ii) the large number of DWS compliance personnel; and (iii) the substantial commitment of resources by DWS and its affiliates to compliance matters.
 
Based on all of the information considered and the conclusions reached, the Board unanimously determined that the continuation of the Agreement is in the best interests of the Fund. In making this determination, the Board did not give particular weight to any single factor identified above. The Board considered these factors over the course of numerous meetings, certain of which were in executive session with only the Independent Trustees and their counsel present. It is possible that individual Trustees may have weighed these factors differently in reaching their individual decisions to approve the continuation of the Agreement.
 
Summary of Management Fee Evaluation by Independent Fee Consultant
 
September 17, 2012
 
Pursuant to an Order entered into by Deutsche Investment Management Americas and affiliates (collectively, "DeAM") with the Attorney General of New York, I, Thomas H. Mack, have been appointed the Independent Fee Consultant for the DWS Funds (formerly the DWS Scudder Funds). My duties include preparing an annual written evaluation of the management fees DeAM charges the Funds, considering among other factors the management fees charged by other mutual fund companies for like services, management fees DeAM charges other clients for like services, DeAM's costs of supplying services under the management agreements and related profit margins, possible economies of scale if a Fund grows larger, and the nature and quality of DeAM's services, including fund performance. This report summarizes my evaluation for 2012, including my qualifications, the evaluation process for each of the DWS Funds, consideration of certain complex-level factors, and my conclusions. I served in substantially the same capacity in 2007, 2008, 2009, 2010 and 2011.
 
Qualifications
 
For more than 35 years I have served in various professional capacities within the investment management business. I have held investment analysis and advisory positions, including securities analyst, portfolio strategist and director of investment policy with a large investment firm. I have also performed business management functions, including business development, financial management and marketing research and analysis.
 
Since 1991, I have been an independent consultant within the asset management industry. I have provided services to over 125 client organizations, including investment managers, mutual fund boards, product distributors and related organizations. Over the past ten years I have completed a number of assignments for mutual fund boards, specifically including assisting boards with management contract renewal.
 
I hold a Master of Business Administration degree, with highest honors, from Harvard University and Master of Science and Bachelor of Science (highest honors) degrees from the University of California at Berkeley. I am an independent director and audit committee financial expert for two closed-end mutual funds and have served in various leadership and financial oversight capacities with non-profit organizations.
 
Evaluation of Fees for each DWS Fund
 
My work focused primarily on evaluating, fund-by-fund, the fees charged to each of the 103 mutual fund portfolios in the DWS Fund family. For each Fund, I considered each of the key factors mentioned above, as well as any other relevant information. In doing so I worked closely with the Funds' Independent Directors in their annual contract renewal process, as well as in their approval of contracts for several new funds (documented separately).
 
In evaluating each Fund's fees, I reviewed comprehensive materials provided by or on behalf of DeAM, including expense information prepared by Lipper Analytical, comparative performance information, profitability data, manager histories, and other materials. I also accessed certain additional information from the Lipper and Morningstar databases and drew on my industry knowledge and experience.
 
To facilitate evaluating this considerable body of information, I prepared for each Fund a document summarizing the key data elements in each area as well as additional analytics discussed below. This made it possible to consider each key data element in the context of the others.
 
In the course of contract renewal, DeAM agreed to implement a number of fee and expense adjustments requested by the Independent Directors which will favorably impact future fees and expenses, and my evaluation includes the effects of these changes.
 
Fees and Expenses Compared with Other Funds
 
The competitive fee and expense evaluation for each fund focused on two primary comparisons:
 
The Fund's contractual management fee (the advisory fee plus the administration fee where applicable) compared with those of a group of typically 12-15 funds in the same Lipper investment category (e.g. Large Capitalization Growth) having similar distribution arrangements and being of similar size.
 
The Fund's total expenses compared with a broader universe of funds from the same Lipper investment category and having similar distribution arrangements.
 
These two comparisons provide a view of not only the level of the fee compared with funds of similar scale but also the total expense the Fund bears for all the services it receives, in comparison with the investment choices available in the Fund's investment category and distribution channel. The principal figure-of-merit used in these comparisons was the subject Fund's percentile ranking against peers.
 
DeAM's Fees for Similar Services to Others
 
DeAM provided management fee schedules for all of its US domiciled fund and non-fund investment management accounts in any of the investment categories where there is a DWS Fund. These similar products included the other DWS Funds, non-fund pooled accounts, institutional accounts and sub-advisory accounts. Using this information, I calculated for each Fund the fee that would be charged to each similar product, at the subject Fund's asset level.
 
Evaluating information regarding non-fund products is difficult because there are varying levels of services required for different types of accounts, with mutual funds generally requiring considerably more regulatory and administrative types of service as well as having more frequent cash flows than other types of accounts. Also, while mutual fund fees for similar fund products can be expected to be similar, there will be some differences due to different pricing conditions in different distribution channels (e.g. retail funds versus those used in variable insurance products), differences in underlying investment processes and other factors.
 
Costs and Profit Margins
 
DeAM provided a detailed profitability analysis for each Fund. After making some adjustments so that the presentation would be more comparable to the available industry figures, I reviewed profit margins from investment management alone, from investment management plus other fund services (excluding distribution) provided to the Funds by DeAM (principally shareholder services), and DeAM profits from all sources, including distribution. A later section comments on overall profitability.
 
Economies of Scale
 
Economies of scale — an expected decline in management cost per dollar of fund assets as fund assets grow — are very rarely quantified and documented because of inherent difficulties in collecting and analyzing relevant data. However, in virtually every investment category that I reviewed, larger funds tend to have lower fees and lower total expenses than smaller funds. To see how each DWS Fund compares with this industry observation, I reviewed:
 
The trend in Fund assets over the last five years and the accompanying trend in total expenses. This shows if the Fund has grown and, if so, whether total expense (management fees as well as other expenses) have declined as a percent of assets.
 
Whether the Fund has break-points in its management fee schedule, the extent of the fee reduction built into the schedule and the asset levels where the breaks take effect, and in the case of a sub-advised Fund how the Fund's break-points compare with those of the sub-advisory fee schedule.
 
How the Fund's contractual fee schedule compares with trends in the industry data. To accomplish this, I constructed a chart showing how actual latest-fiscal-year contractual fees of the Fund and of other similar funds relate to average fund assets, with the subject Fund's contractual fee schedule superimposed.
 
Quality of Service — Performance
 
The quality-of-service evaluation focused on investment performance, which is the principal result of the investment management service. Each Fund's performance was reviewed over the past 1, 3, 5 and 10 years, as applicable, and compared with that of other funds in the same investment category and with a suitable market index.
 
In addition, I calculated and reviewed risk-adjusted returns relative to an index of similar mutual funds' returns and a suitable market index. The risk-adjusted returns analysis provides a way of determining the extent to which the Fund's return comparisons are mainly the product of investment value-added (or lack thereof) or alternatively taking considerably more or less risk than is typical in its investment category.
 
I also received and considered the history of portfolio manager changes for each Fund, as this provided an important context for evaluating the performance results.
 
Complex-Level Considerations
 
While this evaluation was conducted mainly at the individual fund level, there are some issues relating to the reasonableness of fees that can alternatively be considered across the whole fund complex:
 
I reviewed DeAM's profitability analysis for all DWS Funds, with a view toward determining if the allocation procedures used were reasonable and how profit levels compared with public data for other investment managers.
 
I considered whether DeAM and affiliates receive any significant ancillary or "fallout" benefits that should be considered in interpreting the direct profitability results. These would be situations where serving as the investment manager of the Funds is beneficial to another part of the Deutsche Bank organization.
 
I considered how aggregated DWS Fund expenses had varied over the years, by asset class and in the context of trends in asset levels.
 
I considered how aggregated DWS Fund performance measures relative to appropriate peers had varied by asset class and over time.
 
I reviewed the structure of the DeAM organization, trends in staffing levels, and information on compensation of investment management and other professionals compared with industry data.
 
Findings
 
Based on the process and analysis discussed above, which included reviewing a wide range of information from management and external data sources and considering among other factors the fees DeAM charges other clients, the fees charged by other fund managers, DeAM's costs and profits associated with managing the Funds, economies of scale, possible fall-out benefits, and the nature and quality of services provided, in my opinion the management fees charged the DWS Funds are reasonable.

AUDIT COMMITTEE FINANCIAL EXPERT
   
 
The fund’s 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 fund’s Board of Trustees has determined that there are several "audit committee financial experts" (as such term has been defined by the Regulations) serving on the fund’s audit committee including Mr. William McClayton, the chair of the fund’s audit committee. An “audit committee financial expert” is not an “expert” for any purpose, including for purposes of Section 11 of the Securities Act of 1933 and the designation or identification of a person as an “audit committee financial expert” 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.

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

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

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

***
In connection with the audit of the 2011 and 2012 financial statements, the Fund entered into an engagement letter with E&Y.  The terms of the engagement letter required by E&Y, and agreed to by the Audit Committee, include provisions in which the parties consent to the sole jurisdiction of federal courts in New York, Boston or the Northern District of Illinois, as well as a waiver of right to a trial by jury and an exclusion of punitive damages.

***
E&Y advised the Fund’s Audit Committee that E&Y had identified two matters that it determined to be inconsistent with the SEC’s auditor independence rules.
 
First, E&Y advised the Fund’s Audit Committee that, in 2010, an investment advisor for a Covered Person in the Chain of Command (both as defined by SEC rules) purchased for the Covered Person’s account shares of a DWS Fund that is not audited by E&Y. E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X. E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including that the purchase was by the Covered Person’s investment advisor, not by the Covered Person himself and the Covered Person caused the shares of the DWS Fund to be sold immediately upon detection of the purchase.
 
Second, E&Y advised the Fund’s Audit Committee that, in 2010, a Covered Person in the same Office (as defined by SEC rules) as the lead audit engagement partner for the Fund became a trustee and executor to an estate whose assets included shares of a DWS Fund that is not audited by E&Y. E&Y informed the Audit Committee that this investment constituted an investment in an affiliate of an audit client in violation of the Rule 2-01(c)(1) of Regulation S-X. E&Y advised the Audit Committee that E&Y believes its independence has not been impacted as it relates to the audit of the Fund. In reaching this conclusion, E&Y noted a number of factors, including that the shares of the DWS Fund were already an asset of the estate when the Covered Person became executor, the Covered Person caused the shares of the DWS Fund to be sold immediately upon detection in the estate, and the Covered Person was not involved with the provision of audit services to the Fund.
