This report must be preceded or accompanied by a prospectus. To obtain a summary prospectus, if available, or 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 summary prospectus and prospectus contain this and other important information about the fund. Please read the prospectus carefully before you invest.
 
Bond investments are subject to interest-rate and credit risks. When interest rates rise, bond prices generally fall. Credit risk refers to the ability of an issuer to make timely payments of principal and interest. Investments in lower-quality ("junk bonds") and non-rated securities present greater risk of loss than investments in higher-quality securities. The fund invests in inverse floaters, which are derivatives that involve leverage and could magnify the fund's gains or losses. Although the fund seeks income that is exempt from federal income taxes, a portion of the fund's distributions may be subject to federal, state and local taxes, including the alternative minimum tax. See the prospectus for details.

Letter to Shareholders
 
Dear Investor:
 
The first half of 2013 brought welcome evidence that the U.S. economic recovery is gaining traction. Consumer confidence reached its highest level since 2007, U.S. stock market indexes marked a series of record highs and the housing market continues its recovery.
 
According to Asoka Wohrmann, co-chief investment officer for Deutsche Asset & Wealth Management, "The revival of the employment market, good asset performance with rising home and share prices, and an expansive monetary policy gives further growth momentum to the real economy. Accordingly, U.S. economic growth could accelerate in the coming months."
 
Nevertheless, concerns about the European and emerging-market economies persist. Closer to home, the outlook remains guarded when it comes to the eventual end of government intervention in the bond market and the full effects of reduced government spending on employment.
 
Where does this leave you? That depends on a variety of factors, including your overall portfolio allocation. Given the uncertainties in today's bond and stock markets, it may be time for a thoughtful evaluation of your strategy.
 
Talk with a trusted advisor to determine whether any adjustments may be in order, given your specific objectives and risk tolerance. We believe even the most sophisticated investor can benefit from the assistance of a trusted, objective financial professional.
 
Remember that Deutsche Asset & Wealth Management gives you access to Deutsche Bank's global network of economists, analysts and investment professionals. Insights are always at your fingertips at dws-investments.com.

Portfolio Management Review (Unaudited)
 
Overview of Market and Fund Performance
 
All performance information below is historical and does not guarantee future results. Returns shown are for Class A shares, unadjusted for sales charges. 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 most recent month-end performance of all share classes. Fund performance includes reinvestment of all distributions. Unadjusted returns do not reflect sales charges and would have been lower if they had. Please refer to pages 12 through 14 for more complete performance information.
 
DWS Managed Municipal Bond Fund posted a return of 4.01% over the 12 months ended May 31, 2013, while the overall municipal bond market, as measured by the unmanaged Barclays Municipal Bond Index, delivered a total return of 3.05% for the same period. The average fund in the Morningstar Muni National Long category returned 3.80% for the 12 months.
 
Investment Strategy
The fund invests in a wide variety of municipal bonds. These include general obligation bonds, for which payments of principal and interest are secured by the full faith and credit of the issuer and usually supported by the issuer's taxing power. In addition, securities held may include revenue bonds, for which principal and interest are secured by revenues from tolls, rents or other fees gained from the facility that was built with the bond issue proceeds.
The fund's management team seeks to hold municipal bonds that appear to offer the best opportunity to meet the fund's objective of earning tax-exempt income. A number of factors influence the performance of municipal bonds. These include supply and demand, the direction of overall interest rates, and the perceived credit risk associated with an individual municipal issuer. In selecting securities, the managers weigh the impact of the economic outlook and potential interest rate movements on municipal bonds as well as characteristics specific to securities such as coupons, maturity dates and call dates, and supply and demand of the municipal market. Finally, the managers may seek to take advantage if they believe the municipal yield curve presents an opportunity to gain incremental income with limited additional interest rate risk. Although portfolio management may adjust the fund's duration (a measure of sensitivity to interest rates) over a wider range, they generally intend to keep it similar to that of the Barclays Municipal Bond Index, generally between five and nine years.
 
As the period began, with the U.S. Federal Reserve Board (the Fed) maintaining short-term rates anchored near zero, fixed-income markets were closely following developments in the European debt crisis as well as the stream of U.S. economic data. Europe would soon become less of a fulcrum for market sentiment as the European Central Bank (ECB) implemented strong measures to support refinancing by troubled governments. As the period progressed, U.S. housing data seemed to confirm that prices had finally reached a bottom and were beginning to strengthen. In addition, with employment data continuing to disappoint, there was speculation that the Fed would announce further bond purchases under quantitative easing. This speculation was borne out at the Fed's mid-September meeting. The net result was an increased willingness on the part of investors to assume credit risk in exchange for yields higher than the extraordinarily low rates offered from U.S. Treasuries.
 
As November 2012 approached, U.S. fixed-income markets were focused primarily on the presidential election, against a backdrop of wrangling over solutions to the country's fiscal dilemma. The strong demand municipals experienced over the prior several months continued as investors sought tax-exempt income that was attractive relative to taxable U.S. Treasury yields. However, December 2012 saw a retreat in municipal demand levels as institutional investors engaged in selling to lock in gains before year-end and amid some concern over proposals to limit the tax exemption on municipals as part of any budget deal.
As 2013 unfolded, the interest rate environment became less favorable for bond prices overall. Investors shrugged off the lack of meaningful progress in the budget standoff, and U.S. Treasury rates began to trend somewhat higher on optimism over prospects for the economy. Municipals experienced their greatest yield increases and price weakness in the last weeks of the fiscal period. Economic data continued to strengthen and there was mounting speculation that the Fed would begin to scale back its bond purchases that had helped keep longer-term rates in check. In addition, a rising stock market attracted strong investor interest, perhaps drawing flows that may have otherwise gone towards fixed-income securities. Municipal bond funds experienced large outflows as investors found the historically low yields on offer unappealing and sought to minimize exposure to rising interest rates.
 
 
Municipal Bond Yield Curve (as of 5/31/13 and 5/31/12)
 
Source: Municipal Market Data, AAA-rated universe
 
This chart is for illustrative purposes only and is not intended to represent the yield of any DWS fund. Performance is historical and does not guarantee future results.
 
Throughout the period ended May 31, 2013, the Fed kept short-term rates anchored near zero. Along the municipal yield curve, the two-year bond yield decreased 4 basis points over the full 12 months, from 0.33% to 0.29%, while the 30-year yield rose 16 basis points, from 3.08% to 3.24%, resulting in a total steepening of 20 basis points. However, the middle of the yield curve experienced the brunt of the impact of curve steepening, with increases of 30 and 24 basis points for the 10-year and 15-year bond, respectively. (See the graph above for municipal bond yield changes from the beginning to the end of the period.) Credit spreads — the yield differential provided by lower-quality issues vs. AAA-rated issues — generally narrowed for the 12 months as investors sought incremental yield.
 
"As economic data continued to strengthen in 2013, there was increasing speculation that the U.S. Federal Reserve Board (the Fed) would begin to scale back its bond purchases."
 
Positive and Negative Contributors to Fund Performance
 
With a relatively steep yield curve as the period began, we had a tilt in the portfolio towards longer-term issues in the 20-to-30-year maturity range. This exposure added to relative performance as longer-term issues provided incremental income. In addition, with credit spreads at attractive levels, we maintained significant exposure to lower-quality issues in the BBB or A range. This helped performance relative to the benchmark as credit spreads narrowed and prices rose for many of these issues. In particular, exposure to airport revenue bonds and healthcare-related issues added to performance. In addition, the fund had a significant position in California state general obligation bonds, which outperformed as California succeeded in addressing its budgetary imbalance by raising revenue, leading to a ratings upgrade.
 
Performance relative to the benchmark was constrained to a degree by some of our long-standing, higher-coupon holdings as they rolled down into the 10-to-15-year area of the yield curve, which was most impacted by interest rate increases.
 
 
For some of the period, we hedged a portion of the fund's assets against interest rate changes using LIBOR (London Interbank Offered Rate, a benchmark for taxable interest rates) swaps. With a LIBOR swap, we in effect take a short position against the taxable market in order to manage the fund's overall duration and interest rate sensitivity. This helped the fund's return as municipal rates decreased and LIBOR rates increased during the period the hedge was on.
 
Outlook and Positioning
 
Municipal yields, while reasonably attractive relative to U.S. Treasuries, remain at very low levels by historical standards despite the recent uptick in rates. At the end of May 2013, the 10-year municipal bond yield of 2.09% was 98% of the comparable-maturity U.S. Treasury bond yield before taking into account the tax advantage of municipals. The 30-year municipal yield of 3.24% was 99% of the comparable U.S. Treasury yield. Longer-term issues continue to carry a substantial yield advantage and we are continuing to focus purchases on bonds with maturities in the 20-to-30-year range, while seeking exposure to premium coupon issues that can provide a degree of protection against rising interest rates. While credit spreads have narrowed over the last several quarters, we continue to see opportunities, mostly among issues in the A-quality range.
 
The national economic backdrop continues to show gradual improvement, and many state and local governments have continued to show progress in stabilizing their finances. Nonetheless, there remain troubled pockets, and there are also significant uncertainties with respect to the ongoing U.S. budget negotiations as well as Europe's sovereign debt crisis. As a result we believe the expertise we bring to researching municipal sectors and individual issues continues to be of critical importance. For new purchases, we are taking a very cautious approach with respect to general obligation bonds issued by localities, given uncertain levels of state support going forward.

Terms to Know
 
The Barclays Municipal Bond Index is an unmanaged, market-value-weighted measure of municipal bonds issued across the United States. Index issues have a credit rating of at least Baa and a maturity of at least two years.
 
Index returns do not reflect fees or expenses and it is not possible to invest directly into an index.
 
The Morningstar Muni National Long category consists of funds that invest in municipal bonds issued by various state and local governments to fund public projects and are free from federal taxes. These funds spread their assets across many states and sectors and focus on bond durations of seven years or more.
 
Quantitative easing is a government monetary policy often used when interest rates are at or near zero. With this policy government or other securities are purchased from the market, causing the price of the securities purchased to rise and the yield or interest rates on the securities purchased to fall. For the companies whose bonds the central banks are willing to purchase, it means having to pay lower interest rates on new bonds issued to replace existing bonds that have matured. With lower borrowing costs, the central banks hope that consumers will be encouraged to spend more, thus helping the overall economy, and improving the balance sheets for the companies providing the goods and services on which consumers are spending their money.
 
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.
 
One basis point equals 1/100 of a percentage point.
 
Credit quality measures 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. Credit quality does not remove market risk and is subject to change.
 
Credit spread is the additional yield provided by municipal bonds rated AA and below vs. municipals rated AAA with comparable effective maturity.
 
Duration, which is expressed in years, measures the sensitivity of the price of a bond or bond fund to a change in interest rates.
 
Sovereign debt is debt that is issued by a national government.

Fair Value Measurements
 
Various inputs are used in determining the value of the Fund's investments. These inputs are summarized in three broad levels. Level 1 includes quoted prices in active markets for identical securities. Level 2 includes other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds and credit risk). Level 3 includes significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments). The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
 
The following is a summary of the inputs used as of May 31, 2013 in valuing the Fund's investments. For information on the Fund's policy regarding the valuation of investments, please refer to the Security Valuation section of Note A in the accompanying Notes to Financial Statements.

Notes to Financial Statements
 
A. Organization and Significant Accounting Policies
 
DWS Managed Municipal Bond Fund (the "Fund") is a diversified series of DWS Municipal Trust (the "Trust"), which is registered under the Investment Company Act of 1940, as amended (the "1940 Act"), as an open-end management investment company organized as a Massachusetts business trust.
 
The Fund offers multiple classes of shares which provide investors with different purchase options. Class A shares are offered to investors subject to an initial sales charge. Class B shares of the Fund are closed to new purchases, except exchanges or the reinvestment of dividends or other distributions. Class B shares were offered to investors without an initial sales charge and are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions. Class B shares automatically convert to Class A shares six years after issuance. Class C shares are offered to investors without an initial sales charge but are subject to higher ongoing expenses than Class A shares and a contingent deferred sales charge payable upon certain redemptions within one year of purchase. Class C shares do not automatically convert into another class. Institutional Class shares are generally available only to qualified institutions, are not subject to initial or contingent deferred sales charges and generally have lower ongoing expenses than other classes. Class S shares are not subject to initial or contingent deferred sales charges and are only available to a limited group of investors.
 
Investment income, realized and unrealized gains and losses and certain fund-level expenses and expense reductions, if any, are borne pro rata on the basis of relative net assets by the holders of all classes of shares, except that each class bears certain expenses unique to that class such as distribution and services fees, services to shareholders and certain other class-specific expenses. Differences in class-level expenses may result in payment of different per share dividends by class. All shares of the Fund have equal rights with respect to voting subject to class-specific arrangements.
 
The Fund's financial statements are prepared in accordance with accounting principles generally accepted in the United States of America which require the use of management estimates. Actual results could differ from those estimates. The policies described below are followed consistently by the Fund in the preparation of its financial statements.
 
Security Valuation. Investments are stated at value determined as of the close of regular trading on the New York Stock Exchange on each day the exchange is open for trading.
 
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.
 
Municipal debt securities are valued at prices supplied by independent pricing services approved by the Fund's Board, whose valuations are intended to reflect the mean between the bid and asked prices. If the pricing services are unable to provide valuations, the securities are valued at the mean of the most recent bid and asked quotations or evaluated prices, as applicable, obtained from one or more broker-dealers. 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. These securities are generally categorized as Level 2.
 
Swap contracts are valued daily based upon prices supplied by a Board approved pricing vendor, if available, and otherwise are valued at the price provided by the broker-dealer. Swap contracts are generally categorized as Level 2.
 
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 Board and are generally categorized as Level 3. In accordance with the Fund's valuation procedures, factors used in determining value may include, but are not limited to, the type of the security; the size of the holding; the initial cost of the security; the existence of any contractual restrictions on the security's disposition; the price and extent of public trading in similar securities of the issuer or of comparable companies; quotations or evaluated prices from broker-dealers and/or pricing services; information obtained from the issuer, analysts, and/or the appropriate stock exchange (for exchange-traded securities); an analysis of the company's or issuer's financial statements; an evaluation of the forces that influence the issuer and the market(s) in which the security is purchased and sold and with respect to debt securities; the maturity, coupon, creditworthiness, currency denomination and the movement of the market in which the security is normally traded. The value determined under these procedures may differ from published values for the same securities.
 
Disclosure about the classification of fair value measurements is included in a table following the Fund's Investment Portfolio.
 
New Accounting Pronouncement. In January 2013, Accounting Standard Update 2013-01 (ASU 2013-01), Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, replaced Accounting Standards Update 2011-11 (ASU 2011-11), Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 is effective for fiscal years beginning on or after January 1, 2013, and interim periods within those annual periods. ASU 2011-11 was intended to enhance disclosure requirements on the offsetting of financial assets and liabilities. The ASU 2013-01 limits the scope of the new balance sheet offsetting disclosures to derivatives, repurchase agreements, and securities lending transactions to the extent that they are (1) offset in the financial statements or (2) subject to an enforceable master netting arrangement or similar agreement. Management is currently evaluating the application of ASU 2013-01 and its impact, if any, on the Fund's financial statements.
 
Inverse Floaters. The Fund invests in inverse floaters. Inverse floaters are debt instruments with a weekly floating rate of interest that bears an inverse relationship to changes in the short-term interest rate market. Inverse floaters are created by depositing a fixed-rate municipal bond into a special purpose trust (the "Trust"). In turn the Trust issues a short-term floating rate note and an inverse floater. The income stream from the underlying bond in the Trust is divided between the floating rate note and the inverse floater. The income provided by the inverse floater bears an inverse relationship with the short-term rate paid to the floating rate note holder. The short-term floating rate note is issued in a face amount equal to some fraction of the underlying bond's par amount and is paid to a third party, usually a tax-exempt money market fund, at rates that generally reset weekly. The inverse floater earns all of the interest from the underlying fixed-rate bond less the amount of interest paid on the floating rate note and the expenses of the Trust. The inverse floater represents an investment in the underlying bond on a leveraged basis; the Fund bears all of the price risk of the underlying bond in the Trust and receives all the benefits from any potential appreciation of the underlying bond's value. The floating rate notes issued by the Trust are valued at cost, which approximates fair value.
 
By holding the inverse floater, the Fund has the right to collapse the Trust by causing the holders of the floating rate instrument to tender their notes at par and have the broker transfer the underlying bond to the Fund. The floating rate note holder can also elect to tender the note for redemption at par at each reset date. The Fund accounts for these transactions as a form of secured borrowing, by reflecting the value of the underlying bond in the investments of the Fund and the amount owed to the floating rate note holder as a liability under the caption "Payable for floating rate notes issued" in the Statement of Assets and Liabilities. Income earned on the underlying bond is included in interest income, and interest paid on the floaters and the expenses of the Trust are included in "Interest expense and fees on floating rate notes issued" in the Statement of Operations.
 
The Fund may enter into shortfall and forbearance agreements by which the Fund agrees to reimburse the Trust, in certain circumstances, for the difference between the liquidation value of the underlying bond held by the Trust and the liquidation value of the floating rate notes plus any shortfalls in interest cash flows. This could potentially expose the Fund to losses in excess of the value of the Fund's inverse floater investments. In addition, the value of inverse floaters may decrease significantly when interest rates increase. The market for inverse floaters may be more volatile and less liquid than other municipal bonds of comparable maturity. The Trust could be terminated outside of the Fund's control, resulting in a reduction of leverage and disposal of portfolio investments at inopportune times and prices. Investments in inverse floaters generally involve greater risk than in an investment in fixed-rate bonds. In connection with these agreements, securities and/or cash may be pledged as collateral.
 
The weighted average outstanding daily balance of the floating rate notes issued during the year ended May 31, 2013 was $383,135,816, with a weighted average interest rate of 0.73%.
 
When-Issued/Delayed Delivery Securities. The Fund may purchase securities with delivery or payment to occur at a later date beyond the normal settlement period. At the time the Fund enters into a commitment to purchase a security, the transaction is recorded and the value of the transaction is reflected in the net asset value. The price of such security and the date when the security will be delivered and paid for are fixed at the time the transaction is negotiated. The value of the security may vary with market fluctuations. At the time the Fund enters into a purchase transaction it is required to segregate cash or other liquid assets at least equal to the amount of the commitment.
 
Certain risks may arise upon entering into when-issued or delayed delivery transaction from the potential inability of counterparties to meet the terms of their contracts or if the issuer does not issue the securities due to political, economic, or other factors. Additionally, losses may arise due to changes in the value of the underlying securities.
 
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 and tax-exempt income 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.
 
At May 31, 2013, the Fund had net tax basis capital loss carryforwards of approximately $68,894,000, including $1,746,000 of pre-enactment losses which may be applied against any realized net taxable capital gains of each succeeding year until fully utilized or until May 31, 2019, the expiration date, whichever occurs first, and approximately $67,148,000 of post-enactment short-term losses which may be applied against realized net taxable capital gains indefinitely.
 
The Fund has reviewed the tax positions for the open tax years as of May 31, 2013 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. 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 gain distributions are determined annually in accordance with federal tax regulations which may differ from accounting principles generally accepted in the United States of America. These differences primarily relate to investments in inverse floater transactions, certain securities sold at a loss and accretion of market discount on debt securities. As a result, net investment income (loss) and net realized gain (loss) on investment transactions for a reporting period may differ significantly from distributions during such period. Accordingly, the Fund may periodically make reclassifications among certain of its capital accounts without impacting the net asset value of the Fund.
 
At May 31, 2013, the Fund's components of distributable earnings (accumulated losses) on a tax basis were as follows:
Undistributed tax-exempt income
  $ 3,275,054  
Undistributed ordinary income*
  $ 438,570  
Capital loss carryforward
  $ (68,894,000 )
Net unrealized appreciation (depreciation) on investments
  $ 546,687,399  
 
In addition, the tax character of distributions paid to shareholders by the Fund is summarized as follows:
   
Years Ended May 31,
 
   
2013
   
2012
 
Distributions from tax-exempt income
  $ 216,065,900     $ 211,450,277  
Distributions from ordinary income*
  $ 2,424,760     $ 1,124,260  
 
* For tax purposes, short-term capital gain distributions are considered ordinary income distributions.
 
Expenses. Expenses of the Trust arising in connection with a specific fund are allocated to that fund. Other Trust expenses which cannot be directly attributed to a fund are apportioned among the funds in the Trust based upon the relative net assets or other appropriate measures.
 
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 transactions are reported 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 premiums and discounts are amortized/accreted for financial reporting purposes, with the exception of securities in default of principal.
 
Statement of Cash Flows. Information on financial transactions which have been settled through the receipt and disbursement of cash is presented in the Statement of Cash Flows. The cash amount shown in the Statement of Cash Flows represents the cash position at the Fund's custodian bank at May 31, 2013.
 
B. Derivative Instruments
 
Interest Rate Swap Contracts. For the year ended May 31, 2013, the Fund invested into interest rate swap contracts to manage the duration and interest rate sensitivity of the Investment Portfolio. The use of interest rate swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. In an interest rate swap, the Fund agrees to pay to the other party to the interest rate swap (which is known as the "counterparty") a fixed rate payment in exchange for the counterparty agreeing to pay to the Fund a variable rate payment, or the Fund agrees to receive from the counterparty a fixed rate payment in exchange for the counterparty agreeing to receive from the Fund a variable rate payment, the accruals for which would begin at a specified date in the future (the "effective date"). The payment obligations are based on the notional amount of the swap. Certain risks may arise when entering into swap transactions including counterparty default, liquidity or unfavorable changes in interest rates. In connection with these agreements, securities and or cash may be identified as collateral in accordance with the terms of the swap agreements to provide assets of value and recourse in the event of default. The maximum counterparty credit risk is the net present value of the cash flows to be received from or paid to the counterparty over the term of the interest rate swap contract, to the extent that this amount is beneficial to the Fund, in addition to any related collateral posted to the counterparty by the Fund. This risk may be partially reduced by a master netting arrangement between the Fund and the counterparty. The Fund generally intends, but is not obligated, to terminate its interest rate swaps before the effective date. Payments received or made are recorded as realized gain or loss in the Statement of Operations. The value of the swap is adjusted daily based upon a price supplied by a Board approved pricing vendor and the change in value is recorded as unrealized appreciation or depreciation. An upfront payment, if any, made by the Fund is recorded as an asset in the Statement of Assets and Liabilities. An upfront payment, if any, received by the Fund is recorded as a liability in the Statement of Assets and Liabilities. Payments received or made at the end of the measurement period are recorded as realized gain or loss in the Statement of Operations.
 
There were no open interest rate swap contracts as of May 31, 2013. For the year ended May 31, 2013, the investment in interest rate swap contracts had a total notional amount generally indicative of a range from $0 to $255,950,000.
 
Additionally, the amount of unrealized and realized gains and losses on derivative instruments recognized in Fund earnings during the period ended May 31, 2013 and the related location in the accompanying Statement of Operations is summarized in the following tables by primary underlying risk exposure:

Report of Independent Registered Public Accounting Firm
 
To the Trustees of DWS Municipal Trust and the Shareholders of DWS Managed Municipal Bond Fund:
 
In our opinion, the accompanying statement of assets and liabilities, including the investment portfolio, and the related statements of operations, of cash flows and of changes in net assets and the financial highlights present fairly, in all material respects, the financial position of DWS Managed Municipal Bond Fund (the "Fund") at May 31, 2013, and the results of its operations, its cash flows, the changes in its net assets and the financial highlights for each of the periods indicated therein, in conformity with accounting principles generally accepted in the United States of America. These financial statements and financial highlights (hereafter referred to as "financial statements") are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities at May 31, 2013 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

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) 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. 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 (December 1, 2012 to May 31, 2013).
 
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. Subject to certain exceptions, an account maintenance fee of $20.00 assessed once per calendar year for Classes A, B, C and S shares may apply for accounts with balances less than $10,000. This fee is not included in these tables. If it was, the estimate of expenses paid for Classes A, B, C and S shares during the period would be higher, and account value during the period would be lower, by this amount.

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 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.

***
PwC advised the Fund's Audit Committee that it had identified one matter that it determined could be inconsistent with the SEC's auditor independence rules (Rule 2-01(c) of Regulation S-X). As part of a "Global Migration Support" engagement in which PwC's UK network affiliate ("PwC-UK") provided assistance to Deutsche Bank ("DB") with respect to processing internship applications for DB employees seeking short term assignments with DB in the UK, PwC-UK paid application fees on behalf of DB for six applicants at 170 pounds each (1,020 pounds in total).  PwC advised the Committee that it believes that this matter did not affect its objectivity or its impartial judgment in conducting its audit and issuing a report on the financial statements of the Fund as the Fund's independent auditor and confirmed its independence under the SEC’s auditor independence rules. In reaching this conclusion, PwC noted that the engagement team was not aware of the payment of the application fees by PwC-UK and that DB reimbursed PwC-UK for the fees.
