Investment Strategies and Risks

db X-trackers Ultra-Short Duration Bond Fund

Under normal circumstances, the Fund invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in debt securities. Debt securities include securities of U.S. and foreign government agencies and instrumentalities, corporate securities, mortgage-backed and asset backed securities, taxable municipal and tax-exempt municipal bonds, adjustable rate loans that have a senior right to payment (“senior loans”), and other floating-rate debt securities.

The Fund may invest in investment-grade (rated BBB- or higher by Standard & Poor’s Rating Services, Inc. (“S&P”) and Fitch, Inc. (“Fitch”) or Baa3 or higher by Moody’s Investor Service, Inc. (“Moody’s”) or, if unrated, determined by the Fund’s Adviser and/or Sub-Adviser to be of comparable quality) and high yield debt securities (rated BB+ or lower by S&P and Fitch or Ba1 or lower by Moody’s, or, if unrated, determined by the Fund’s Adviser and/or Sub-Adviser to be of comparable quality) debt securities of U.S. and foreign issuers, including issuers located in countries with new or emerging securities markets. Under normal market conditions, the Fund currently does not intend to hold more than 10% of its total assets in non-U.S. dollar denominated debt securities. The Fund’s investments in high yield debt securities, including non-investment grade senior loans and other non-investment grade floating-rate debt securities, will be limited to 50% of its total assets.

The senior loans in which the Fund will invest generally will be loans rated by a Nationally Recognized Statistical Rating Organization (“NRSRO”). However, the Fund also may invest in senior loans that (i) may not be rated by a NRSRO or any state securities commission, or listed on any national exchange; or (ii) are not secured by collateral.

The Fund may invest in mortgage-backed and asset-backed securities. Mortgage-backed securities are mortgage-related securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities, or issued by non-government entities. Mortgage-related securities represent pools of mortgage loans assembled for sale to investors by various government agencies such as Government National Mortgage Association (“GNMA”) and government-related organizations such as Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”), as well as by non-governmental issuers such as commercial banks, savings and loan institutions, mortgage bankers and private mortgage insurance companies. Other asset-backed securities are structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include items such as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property, and receivables from credit card agreements and from sales of personal property. Asset-backed securities typically have no U.S. Government backing. The Fund will limit investments in mortgage-backed and asset-backed securities issued or guaranteed by non-government entities to 15% of the Fund’s net assets.

The Fund may invest a portion of its assets in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. government-sponsored enterprises: GNMA, FNMA, or FHLMC.

The Fund may hold up to 20% of its total assets in cash or money market instruments in order to maintain liquidity, or in the event portfolio management determines that securities meeting the Fund’s investment objective are not otherwise readily available for purchase.

If market conditions make it difficult to value some investments, the Fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different than the value realized upon such investment’s sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods, which may prevent the Fund from being able to realize full value and thus sell a security for its full valuation. This could cause a material decline in the Fund’s net asset value.

db X-trackers Managed Municipal Bond Fund

Under normal circumstances, the Fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in securities issued by municipalities across the United States (including the Commonwealth of Puerto Rico and U.S. territories such as the U.S. Virgin Islands and Guam) whose income is free from regular federal income tax. The Fund considers any investments in municipal securities that pay interest subject to the alternative minimum tax (“AMT”) as part of the 80% of the Fund’s net assets that must be invested in municipal securities.

The Fund may buy municipal securities of all maturities. These may include revenue bonds (which are backed by revenues from a particular source) and general obligation bonds (which are typically backed by the issuer’s ability to levy taxes). They may also include municipal lease obligations and investments representing an interest therein.

The Fund normally invests at least 65% of total assets in municipal securities of the top credit quality (rated AAA+ through A- by S&P and Fitch or Aaa1 through A3 by Moody’s or, if unrated, determined by the Fund’s Adviser and/or Sub-Adviser to be of comparable quality). The Fund may invest up to 10% of total assets in high yield debt securities (commonly referred to as “junk” bonds) rated BB+ or lower by S&P and Fitch or Ba1 or lower by Moody’s or, if unrated, determined by the Fund’s Adviser and/or Sub-Adviser to be of comparable quality.

To the extent that the db X-trackers Managed Municipal Bond Fund concentrates its investments in a single state, region or sector of the municipal securities market, its performance can be more volatile than that of a fund that invests more broadly. As an example, factors affecting a state, region or sector such as severe fiscal difficulties, an economic downturn, court rulings, increased expenditures on domestic security or reduced monetary support from the federal government could over time impair a states, region or sector’s ability to repay its obligations.

Diversification Status. Each Fund is classified as “non-diversified.” A non-diversified fund is a fund that is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. The securities of a particular issuer (or securities of issuers in particular industries) may dominate the underlying index of such a fund and, consequently, the fund’s investment portfolio. This may adversely affect the fund’s performance or subject the fund’s Shares to greater price volatility than that experienced by more diversified investment companies.

Each Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a regulated investment company (“RIC”) for purposes of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), and to relieve the Fund of any liability for U.S. federal income tax to the extent that its earnings are distributed to shareholders, provided that the Fund satisfies a minimum distribution requirement. Compliance with the diversification requirements of the Code may limit the investment flexibility of the Funds and may make it less likely that such Funds will meet their investment objective.

Bonds. Each Fund invests in U.S. registered, dollar-denominated bonds. A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date. An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Other types of bonds bear income at an interest rate that is adjusted periodically. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral).

Corporate Bonds. The db X-trackers Ultra-Short Duration Bond Fund may invest in investment grade corporate bonds. The investment return of corporate bonds reflects interest on the security and changes in the market value of the security. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by an instrument.

High Yield Securities. Each Fund may invest in high yield securities (“junk bonds”), which are debt securities that are rated below investment grade by nationally recognized statistical rating organizations, or are unrated securities that the Investment Adviser believes are of comparable quality. Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of a Fund than a fund that invests in higher-rated securities.

Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual corporate developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by a Fund.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which a Fund could sell a high yield security, and could adversely affect the daily net asset value per share of the Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available. However, when investing in high yield securities the Funds intend to invest primarily in high yield securities that the Investment Adviser believes have greater liquidity than the broader high yield securities market as a whole.

The use of credit ratings as a principal method of selecting high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated.

U.S. Government Obligations. Each Fund may invest a portion of its assets in various types of U.S. Government obligations. U.S. Government obligations are a type of bond. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities. Payment of principal and interest on U.S. Government obligations (i) may be backed by the full faith and credit of the United States (as with U.S. Treasury obligations and GNMA certificates) or (ii) may be backed solely by the issuing or guaranteeing agency or instrumentality itself (as with FNMA), FHLMC and Federal Home Loan Bank notes. In the latter case, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, which agency or instrumentality may be privately owned. There can be no assurance that the U.S. Government would provide financial support to its agencies or instrumentalities where it is not obligated to do so. As a general matter, the value of debt instruments, including U.S. Government obligations, declines when market interest rates increase and rises when market interest rates decrease. Certain types of U.S. Government obligations are subject to fluctuations in yield or value due to their structure or contract terms.

Convertible Securities. The db X-trackers Ultra-Short Duration Bond Fund may invest in convertible securities. Convertible securities include bonds, debentures, notes, preferred stocks and other securities that may be converted into a prescribed amount of common stock or other equity securities at a specified price and time. The holder of convertible securities is entitled to receive interest paid or accrued on debt, or dividends paid or accrued on preferred stock, until the security matures or is converted. The value of a convertible security depends on interest rates, the yield of similar nonconvertible securities, the financial strength of the issuer and the seniority of the security in the issuer’s capital structure. Convertible securities may be illiquid and may be required to convert at a time and at a price that is unfavorable to the Fund. To the extent that the Fund invest in convertible securities with credit ratings below investment grade, such securities may have a higher likelihood of default, although this may be somewhat offset by the convertibility feature.

Mortgage-Backed and Asset-Backed Securities. The db X-trackers Ultra-Short Duration Bond Fund may invest in mortgage-backed and asset-backed securities. Mortgage-backed securities are mortgage-related securities issued or guaranteed by the U.S. Government, its agencies and instrumentalities, or issued by non-government entities. Mortgage-related securities represent pools of mortgage loans assembled for sale to investors by various government agencies such as GNMA and government-related organizations such as FNMA and FHLMC, as well as by non-government issuers such as commercial banks, savings and loan institutions, mortgage bankers and private mortgage insurance companies. Although certain mortgage-related securities are guaranteed by a third party or otherwise similarly secured, the market value of the security, which may fluctuate, is not so secured.

4

Other asset-backed securities are structured like mortgage-backed securities, but instead of mortgage loans or interests in mortgage loans, the underlying assets may include items such as motor vehicle installment sales or installment loan contracts, leases of various types of real and personal property, and receivables from credit card agreements and from sales of personal property. Asset-backed securities typically have no U.S. Government backing. Additionally, the ability of an issuer of asset-backed securities to enforce its security interest in the underlying assets may be limited.

If the Fund purchases a mortgage-backed or other asset-backed security at a premium, that portion may be lost if there is a decline in the market value of the security whether resulting from changes in interest rates or prepayments in the underlying collateral. As with other interest-bearing securities, the prices of such securities are inversely affected by changes in interest rates. Although the value of a mortgage-backed or other asset-backed security may decline when interest rates rise, the converse is not necessarily true, since in periods of declining interest rates the mortgages and loans underlying the securities are prone to prepayment, thereby shortening the average life of the security and shortening the period of time over which income at the higher rate is received. When interest rates are rising, the rate of prepayment tends to decrease, thereby lengthening the period of time over which income at the lower rate is received. For these and other reasons, a mortgage-backed or other asset-backed security’s average maturity may be shortened or lengthened as a result of interest rate fluctuations and, therefore, it is not possible to predict accurately the security’s return.

Mortgage Pass-Through Securities. The db X-trackers Ultra-Short Duration Bond Fund may invest a portion of its assets in U.S. agency mortgage pass-through securities. The term “U.S. agency mortgage pass-through security” refers to a category of pass-through securities backed by pools of mortgages and issued by one of several U.S. government-sponsored enterprises: GNMA, FNMA or FHLMC. In the basic mortgage pass-through structure, mortgages with similar issuer, term and coupon characteristics are collected and aggregated into a “pool” consisting of multiple mortgage loans. The pool is assigned a CUSIP number and undivided interests in the pool are traded and sold as pass-through securities. The holder of the security is entitled to a pro rata share of principal and interest payments (including unscheduled prepayments) from the pool of mortgage loans.

An investment in a specific pool of pass-through securities requires an analysis of the specific prepayment risk of mortgages within the covered pool (since mortgagors typically have the option to prepay their loans). The level of prepayments on a pool of mortgage securities is difficult to predict and can impact the subsequent cash flows and value of the mortgage pool. In addition, when trading specific mortgage pools, precise execution, delivery and settlement arrangements must be negotiated for each transaction. These factors combine to make trading in mortgage pools somewhat cumbersome.

For the foregoing and other reasons, the Fund seeks to obtain exposure to U.S. agency mortgage pass-through securities primarily through the use of “to-be-announced” or “TBA transactions.” “TBA” refers to a commonly used mechanism for the forward settlement of U.S. agency mortgage pass-through securities, and not to a separate type of mortgage-backed security. Most transactions in mortgage pass-through securities occur through the use of TBA transactions. TBA transactions generally are conducted in accordance with widely-accepted guidelines which establish commonly observed terms and conditions for execution, settlement and delivery. In a TBA transaction, the buyer and seller decide on general trade parameters, such as agency, settlement date, par amount, and price. The actual pools delivered generally are determined two days prior to settlement date.

Default by or bankruptcy of a counterparty to a TBA transaction would expose the Fund to possible loss because of adverse market action, expenses or delays in connection with the purchase or sale of the pools of mortgage pass-through securities specified in the TBA transaction. To minimize this risk, the Fund will enter into TBA transactions only with established counterparties (such as major broker-dealers) and the Investment Adviser will monitor the creditworthiness of such counterparties. In addition, the Fund may accept assignments of TBA transactions from Authorized Participants (as defined below) from time to time. The Fund’s use of “TBA rolls” may cause the Fund to experience higher portfolio turnover, higher transaction costs and to pay higher capital gain distributions to shareholders (which may be taxable).

Most transactions in fixed-rate mortgage pass-through securities occur through standardized contracts for future delivery in which the exact mortgage pools to be delivered are not specified until a few days prior to settlements (a “TBA” transaction). The Fund may enter into such contracts on a regular basis. The Fund, pending settlement of such contracts, will invest its assets in high-quality, liquid short-term instruments, including shares of money market funds. The Fund will assume its pro rata share of the fees and expenses of any money market fund that it may invest in, in addition to the Fund’s own fees and expenses. The Fund may also acquire interests in mortgage pools through means other than such standardized contracts for future delivery. The Fund may also invest the cash collateral it holds as part of its TBA transactions in repurchase agreements.

5

Bank Instruments. The db X-trackers Ultra-Short Duration Bond Fund may invest in certificates of deposit (“CDs”), time deposits and bankers’ acceptances from U.S. banks. A bankers’ acceptance is a bill of exchange or time draft drawn on and accepted by a commercial bank. A CD is a negotiable interest-bearing instrument with a specific maturity. CDs are issued by banks and savings and loan institutions in exchange for the deposit of funds and normally can be traded in the secondary market prior to maturity. A time deposit is a nonnegotiable receipt issued by a bank in exchange for the deposit of funds. Like a CD, it earns a specified rate of interest over a definite period of time; however, it cannot be traded in the secondary market.

Loans. Loans consist generally of obligations of companies and other entities (collectively, “borrowers”) incurred for the purpose of reorganizing the assets and liabilities of a borrower; acquiring another company; taking over control of a company (leveraged buyout); temporary refinancing; or financing internal growth or other general business purposes. Loans are often obligations of borrowers who have incurred a significant percentage of debt compared to equity issued and thus are highly leveraged. All or a significant portion of the loans in which the db X-trackers Ultra-Short Duration Bond Fund will invest may be below investment grade quality.

Loans may be acquired by direct investment as a lender at the inception of the loan or by assignment of a portion of a loan previously made to a different lender or by purchase of a participation interest. If the Fund makes a direct investment in a loan as one of the lenders, it generally acquires the loan at par. This means the Fund receives a return at the full interest rate for the loan. If the Fund acquires its interest in loans in the secondary market or acquires a participation interest, the loans may be purchased or sold above, at, or below par, which can result in a yield that is below, equal to, or above the stated interest rate of the loan. The Fund will generally purchase loans from banks or other financial institutions through assignments or participations.

When the Fund acts as one of a group of lenders originating a senior loan, it may participate in structuring the senior loan and have a direct contractual relationship with the borrower, may enforce compliance by the borrower with the terms of the loan agreement and may have rights with respect to any funds acquired by other lenders through set-offs. Lenders also have full voting and consent rights under the applicable loan agreement. Action subject to lender vote or consent generally requires the vote or consent of the holders of some specified percentage of the outstanding principal amount of the senior loan. Certain decisions, such as reducing the amount of interest on or principal of a senior loan, releasing collateral, changing the maturity of a senior loan or a change in control of the borrower, frequently require the unanimous vote or consent of all lenders affected.

When the Fund is a purchaser of an assignment, it succeeds to all the rights and obligations under the loan agreement of the assigning lender and becomes a lender under the loan agreement with the same rights and obligations as the assigning lender. These rights include the ability to vote along with the other lenders on such matters as enforcing the terms of the loan agreement ( e.g. , declaring defaults, initiating collection action, etc.). Taking such actions typically requires at least a vote of the lenders holding a majority of the investment in the loan and may require a vote by lenders holding two-thirds or more of the investment in the loan. Because the Fund usually does not hold a majority of the investment in any loan, it will not be able by itself to control decisions that require a vote by the lenders. Assignments may be arranged through private negotiations and the rights and obligations acquired by the purchase of an assignment may differ from, and be more limited than, those held by the assigning lender.

Historically, the amount of public information available about a specific loan has been less extensive than if the loan were registered or exchange-traded.

The loans in which the Fund may invest will often be secured and senior to other indebtedness of the borrower. Each loan will generally be secured by collateral such as accounts receivable, inventory, equipment, real estate, intangible assets such as trademarks, copyrights and patents, and securities of subsidiaries or affiliates. Collateral may also include guarantees or other credit support by affiliates of the borrower. The value of the collateral generally will be determined by reference to financial statements of the borrower, by an independent appraisal, by obtaining the market value of such collateral, in the case of cash or securities if readily ascertainable, or by other customary valuation techniques considered appropriate by the Investment Adviser. The value of collateral may decline after the Fund’s investment, and collateral may be difficult to sell in the event of default. Consequently, the Fund may not receive all the payments to which it is entitled. The loan agreement may or may not require the borrower to pledge additional collateral to secure the senior loan if the value of the initial collateral declines. In certain circumstances, the loan agreement may authorize the agent to liquidate the collateral and to distribute the liquidation proceeds pro rata among the lenders. By virtue of their senior position and collateral, senior loans typically provide lenders with the first right to cash flows or proceeds from the sale of a borrower’s collateral if the borrower becomes insolvent (subject to the limitations of bankruptcy law, which may provide higher priority to certain claims such as employee salaries, employee pensions, and taxes). This means senior loans are generally repaid before unsecured bank loans, corporate bonds, subordinated debt, trade creditors, and preferred or common stockholders. To the extent that the Fund invests in unsecured loans, if the borrower defaults on such loan, there is no specific collateral on which the lender can foreclose. If the borrower defaults on a subordinated loan, the collateral may not be sufficient to cover both the senior and subordinated loans. In addition, if the loan is foreclosed, the Fund could become part owner of any collateral and could bear the costs and liabilities of owning and disposing of the collateral.

6

The Fund may purchase and retain in its portfolio senior loans of borrowers that have filed for protection under the federal bankruptcy laws or that have had involuntary bankruptcy petitions filed against them by creditors. Investing in senior loans involves investment risk, and some borrowers default on their senior loan payments.

Senior loans typically pay interest at least quarterly at rates which equal a fixed percentage spread over a base rate such as the London Inter-Bank Offered Rate (“LIBOR”). For example, if LIBOR were 3% and the borrower was paying a fixed spread of 2.50%, the total interest rate paid by the borrower would be 5.50%. Although a base rate such as LIBOR can change every day, loan agreements for senior loans typically allow the borrower the ability to choose how often the base rate for its loan will change. A single loan may have multiple reset periods at the same time, with each reset period applicable to a designated portion of the loan. Such periods can range from one day to one year, with most borrowers choosing monthly or quarterly reset periods. During periods of rising interest rates, borrowers will tend to choose longer reset periods, and during periods of declining interest rates, borrowers will tend to choose shorter reset periods. The fixed spread over the base rate on a senior loan typically does not change.

Senior loans usually have mandatory and optional prepayment provisions. Because of prepayments, the actual remaining maturity of senior loans may be considerably less than their stated maturity. Senior loans generally are arranged through private negotiations between a borrower and several financial institutions represented by an agent who is usually one of the originating lenders. In larger transactions, it is common to have several agents; however, generally only one such agent has primary responsibility for ongoing administration of a senior loan. Agents are typically paid fees by the borrower for their services.

The agent is primarily responsible for negotiating the loan agreement which establishes the terms and conditions of the senior loan and the rights of the borrower and the lenders. The agent is paid a fee by the borrower for its services. The agent generally is required to administer and manage the senior loan on behalf of other lenders. The agent also is responsible for monitoring collateral and for exercising remedies available to the lenders such as foreclosure upon collateral. The agent may rely on independent appraisals of specific collateral. The agent need not, however, obtain an independent appraisal of assets pledged as collateral in all cases. The agent generally is also responsible for determining that the lenders have obtained a perfected security interest in the collateral securing a senior loan. The Fund normally relies on the agent to collect principal of and interest on a senior loan. Furthermore, the Fund also relies in part on the agent to monitor compliance by the borrower with the restrictive covenants in the loan agreement and to notify the Fund (or the lender from whom the Fund has purchased a participation) of any adverse change in the borrower’s financial condition. Insolvency of the agent or other persons positioned between the Fund and the borrower could result in losses for the Fund.

Participation Interests. The db X-trackers Ultra-Short Duration Bond Fund may purchase participations in corporate loans. Participation interests generally will be acquired from a commercial bank or other financial institution (a “Lender”) or from other holders of a participation interest (a “Participant”). The purchase of a participation interest either from a Lender or a Participant will not result in any direct contractual relationship with the borrowing company (the “Borrower”). The Fund generally will have no right directly to enforce compliance by the Borrower with the terms of the credit agreement. Instead, the Fund will be required to rely on the Lender or the Participant that sold the participation interest, both for the enforcement of the Fund’s rights against the Borrower and for the receipt and processing of payments due to the Funds under the loans. Under the terms of a participation interest, the Funds may be regarded as a member of the Participant, and thus the Funds are subject to the credit risk of both the Borrower and a Participant. Participation interests are generally subject to restrictions on resale. Generally, the Funds consider participation interests to be illiquid and therefore subject to the Fund’s percentage limitations for investments in illiquid securities.

Commercial Instruments. The db X-trackers Ultra-Short Duration Bond Fund may invest in commercial interests, including commercial paper, asset-backed commercial paper and other short-term corporate instruments. Commercial paper normally represents short-term unsecured promissory notes issued in bearer form by banks or bank holding companies, corporations, finance companies and other issuers. Commercial paper may be traded in the secondary market after its issuance. Asset-backed commercial paper is issued by a special purpose entity that is organized to issue the commercial paper and to purchase trade receivables or other financial assets. The credit quality of asset backed commercial paper depends primarily on the quality of these assets and the level of any additional credit support.

Zero-Coupon and Pay-in-Kind Securities. The Funds may invest in zero-coupon or pay-in-kind securities. These securities are debt securities that do not make regular cash interest payments. Zero-coupon securities are sold at a deep discount to their face value. Pay-in-kind securities pay interest through the issuance of additional securities. Because zero-coupon and pay-in-kind securities do not pay

7

current cash income, the price of these securities can be volatile when interest rates fluctuate. While these securities do not pay current cash income, federal tax law requires the holders of zero-coupon and pay-in-kind securities to include in income each year the portion of the original issue discount (or deemed discount) and other non-cash income on such securities accrued during that year. In order to qualify as a “regulated investment company” under the Code, and to avoid certain excise taxes, the Funds may be required to distribute a portion of such discount and income and may be required to dispose of other portfolio securities, which could occur during periods of adverse market prices, in order to generate sufficient cash to meet these distribution requirements.

Delayed Delivery Transactions. The Funds may use delayed delivery transactions as an investment technique. Delayed delivery transactions, also referred to as forward commitments, involve commitments by the Funds to dealers or issuers to acquire or sell securities at a specified future date beyond the customary settlement for such securities. These commitments may fix the payment price and interest rate to be received or paid on the investment. The Funds may purchase securities on a delayed delivery basis to the extent that it can anticipate having available cash on the settlement date. Delayed delivery agreements will not be used as a speculative or leverage technique.

Investment in securities on a delayed delivery basis may increase the Funds’ exposure to market fluctuation and may increase the possibility that the Funds will incur short-term gains subject to federal taxation or short-term losses if the Funds must engage in portfolio transactions in order to honor a delayed delivery commitment. Until the settlement date, the Funds will segregate liquid assets of a dollar value sufficient at all times to make payment for the delayed delivery transactions. Such segregated liquid assets will be marked-to-market daily, and the amount segregated will be increased if necessary to maintain adequate coverage of the delayed delivery commitments.

The delayed delivery securities, which will not begin to accrue interest or dividends until the settlement date, will be recorded as an asset of the Funds and will be subject to the risk of market fluctuation. The purchase price of the delayed delivery securities is a liability of the Funds until settlement. The Funds may enter into buy/sell back transactions (a form of delayed delivery agreement). In a buy/sell back transaction, the Funds enter a trade to sell securities at one price and simultaneously enters a trade to buy the same securities at another price for settlement at a future date.

When-Issued Securities. The Funds may purchase when-issued securities. Purchasing securities on a “when-issued” basis means that the date for delivery of and payment for the securities is not fixed at the date of purchase, but is set after the securities are issued. The payment obligation and, if applicable, the interest rate that will be received on the securities are fixed at the time the buyer enters into the commitment. The Funds will only make commitments to purchase such securities with the intention of actually acquiring such securities, but the Funds may sell these securities before the settlement date if it is deemed advisable.

Securities purchased on a when-issued basis and the securities held in a Fund’s portfolio are subject to changes in market value based upon the public’s perception of the creditworthiness of the issuer and, if applicable, the changes in the level of interest rates. Therefore, if a Fund is to remain substantially fully invested at the same time that it has purchased securities on a when-issued basis, there will be a possibility that the market value of the Fund’s assets will fluctuate to a greater degree. Furthermore, when the time comes for a Fund to meet its obligations under when-issued commitments, the Fund will do so by using then available cash flow, by sale of the segregated liquid assets, by sale of other securities, or although it would not normally expect to do so, by directing the sale of when-issued securities themselves (which may have a market value greater or less than the Fund’s payment obligation).

Investment in securities on a when-issued basis may increase a Fund’s exposure to market fluctuation and may increase the possibility that the Fund will incur short-term gains subject to federal taxation or short-term losses if the Fund must sell another security in order to honor a when-issued commitment. A Fund will employ techniques designed to reduce such risks. If a Fund purchases a when-issued security, the Fund will segregate liquid assets in an amount equal to the when-issued commitment. If the market value of such segregated assets declines, additional liquid assets will be segregated on a daily basis so that the market value of the segregated assets will equal the amount of a Fund’s when-issued commitments.

Repurchase Agreements. Each Fund may enter into repurchase agreements. A repurchase agreement is an instrument under which the purchaser ( i.e. , a Fund) acquires the security and the seller agrees, at the time of the sale, to repurchase the security at a mutually agreed upon time and price, thereby determining the yield during the purchaser’s holding period. Repurchase agreements may be construed to be collateralized loans by the purchaser to the seller secured by the securities transferred to the purchaser. If a repurchase agreement is construed to be a collateralized loan, the underlying securities will not be considered to be owned by each Fund but only to constitute collateral for the seller’s obligation to pay the repurchase price, and, in the event of a default by the seller, each Fund may suffer time delays and incur costs or losses in connection with the disposition of the collateral.

8

In any repurchase transaction, collateral for a repurchase agreement may include cash items, obligations issued by the U.S. government or its agencies or instrumentalities, obligations rated in the highest category by at least two NRSROs, or, if unrated, determined to be of comparable quality by the Adviser and/or Sub-Adviser. Collateral, however, is not limited to the foregoing and may include for example obligations rated below the highest category by NRSROs. Collateral for a repurchase agreement may also include securities that a Fund could not hold directly without the repurchase obligation. Irrespective of the type of collateral underlying the repurchase agreement, a repurchase obligation with a particular counterparty must satisfy the credit quality standards applicable to the acquisition of an instrument issued by such counterparty in compliance with Rule 2a-7 under the 1940 Act.

Repurchase agreements pose certain risks for a Fund that utilizes them. Such risks are not unique to the Funds but are inherent in repurchase agreements. The Funds seek to minimize such risks but because of the inherent legal uncertainties involved in repurchase agreements, such risks cannot be eliminated. Lower quality collateral and collateral with longer maturities may be subject to greater price fluctuations than higher quality collateral and collateral with shorter maturities. If the repurchase agreement counterparty were to default, lower quality collateral may be more difficult to liquidate than higher quality collateral. Should the counterparty default and the amount of collateral not be sufficient to cover the counterparty’s repurchase obligation, a Fund would retain the status of an unsecured creditor of the counterparty ( i.e. , the position the Fund would normally be in if it were to hold, pursuant to its investment policies, other unsecured debt securities of the defaulting counterparty) with respect to the amount of the shortfall. As an unsecured creditor, a Fund would be at risk of losing some or all of the principal and income involved in the transaction.

Reverse Repurchase Agreements. Each Fund may enter into reverse repurchase agreements, which involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. Generally the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are advantageous only if the Fund has an opportunity to earn a rate of interest on the cash derived from these transactions that is greater than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and each Fund intends to use the reverse repurchase technique only when the Adviser and/or Sub-Adviser believe it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of each Fund’s assets. The Fund’s exposure to reverse repurchase agreements will be covered by assets having a value equal to or greater than such commitments. Each Fund maintains liquid assets in connection with reverse repurchase agreements. Under the 1940 Act, reverse repurchase agreements are considered borrowings.

Currency Transactions. The db X-trackers Ultra-Short Duration Bond Fund may enter into forward currency contracts designed to offset a Fund’s exposure to non-U.S. currencies. In addition, the Fund may enter into foreign currency forward contracts and foreign currency futures contracts to facilitate local securities settlements or to protect against currency exposure in connection with distributions to Shareholders.

A foreign currency forward exchange contract (“forward contract”) involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts are principally traded in the interbank market conducted directly between currency traders (usually large, commercial banks) and their customers. A forward contract generally has no margin deposit requirement, and no commissions are charged at any stage for trades.

A non-deliverable forward contract (“NDF”) is a forward contract where there is no physical settlement of two currencies at maturity. NDFs are contracts between parties in which a net settlement amount based on the change in the specified foreign exchange rate is paid by one party to the other. The Fund’s obligations with respect to each NDF is accrued on a daily basis and an amount of cash or liquid securities at least equal to such amount maintained in an account at the Trust’s custodian bank. The risk of loss with respect to NDFs generally is limited to the net amount of payments that a Fund is contractually obligated to make or receive.

A foreign currency futures contract is a contract involving an obligation to deliver or acquire the specified amount of a specific currency, at a specified price and at a specified future time. Futures contracts may be settled on a net cash payment basis rather than by the sale and delivery of the underlying currency.

Short-Term Instruments and Temporary Investments . Each Fund may invest in short-term instruments, including money market instruments, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) Shares of money market funds (including those advised by the Adviser and/or Sub-Adviser); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-

9

sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed-time deposits and other obligations of U.S. and non-U.S. banks (including non-U.S. branches) and similar institutions; (iv) commercial paper rated, at the date of purchase, “Prime-1” by Moody’s ^® Investors Service, Inc. or “A-1” by S&P, or if unrated, of comparable quality as determined by the Adviser and/or Sub-Adviser; (v) non-convertible corporate debt securities ( e.g. , bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; (vi) repurchase agreements; and (vii) short-term U.S. dollar-denominated obligations of non-U.S. banks (including U.S. branches) that, in the opinion of the Adviser and/or Sub-Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by a Fund. Any of these instruments may be purchased on a current or forward-settled basis. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

Foreign Securities. The Funds may invest in fixed income securities issued by entities outside the U.S. Investing in the securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. issuers. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in foreign countries, and potential restrictions on the flow of international capital. Foreign issuers may be subject to less governmental regulation than U.S. issuers. Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

Restricted Securities/Rule 144A Securities. The Funds may invest in securities offered pursuant to Rule 144A under the 1933 Act (“Rule 144A securities”), which are restricted securities. They may be less liquid and more difficult to value than other investments because such securities may not be readily marketable in broad public markets. The Funds may not be able to sell a restricted security promptly or at a reasonable price. Although there is a substantial institutional market for Rule 144A securities, it is not possible to predict exactly how the market for Rule 144A securities will develop. A restricted security that was liquid at the time of purchase may subsequently become illiquid and its value may decline as a result. Restricted securities that are deemed illiquid will count towards a Fund’s 15% limitation on illiquid securities. In addition, transaction costs may be higher for restricted securities than for more liquid securities. The Funds may have to bear the expense of registering Rule 144A securities for resale and the risk of substantial delays in effecting the registration.

Securities of Investment Companies. Each Fund may invest in the securities of other investment companies (including money market funds) and real estate investment trusts (“REITs”) to the extent allowed by law. Pursuant to the 1940 Act, a Fund’s investment in investment companies is limited to, subject to certain exceptions: (i) 3% of the total outstanding voting stock of any one investment company; (ii) 5% of the Fund’s total assets with respect to any one investment company and (iii) 10% of the Fund’s total assets with respect to investment companies in the aggregate. To the extent allowed by law or regulation, each Fund may invest its assets in the securities of investment companies that are money market funds, including those advised by the Adviser and/or Sub-Adviser or otherwise affiliated with the Adviser and/or Sub-Adviser, in excess of the limits discussed above. Other investment companies in which a Fund invests can be expected to incur fees and expenses for operations, such as investment advisory and administration fees that would be in addition to those incurred by the Fund.

Illiquid Securities. Each Fund may invest up to an aggregate amount of 15% of its net assets in illiquid securities (calculated at the time of investment). Illiquid securities include securities subject to contractual or other restrictions on resale and other instruments that lack readily available markets.

Futures and Options. Each Fund may enter into futures contracts and options. These futures contracts and options will be used to facilitate trading or reduce transaction costs. Each Fund will enter into futures contracts and options that are traded on a U.S. or non-U.S. exchange. No Fund will use futures or options for speculative purposes. Each Fund intends to use futures and options in accordance with Rule 4.5 promulgated under the Commodity Exchange Act (“CEA”). The Adviser, on behalf of each Fund, has claimed an exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that each Fund is not subject to registration or regulation as a commodity pool operator under the CEA.

Futures contracts provide for the future sale by one party and purchase by another party of a specified amount of a specific instrument or index at a specified future time and at a specified price. Each Fund may enter into futures contracts to purchase the value of one or more securities indexes when the Adviser and/or Sub-Adviser anticipate purchasing the underlying securities and believe prices will rise before the purchase will be made. To the extent required by law, liquid assets committed to futures contracts will be maintained.

10

A call option gives a holder the right to purchase a specific security at a specified price (“exercise price”) within a specified period of time. A put option gives a holder the right to sell a specific security at a specified exercise price within a specified period of time. The initial purchaser of a call option pays the “writer” a premium, which is paid at the time of purchase and is retained by the writer whether or not such option is exercised. Each Fund may purchase put options to hedge its portfolio against the risk of a decline in the market value of securities held and may purchase call options to hedge against an increase in the price of securities it is committed to purchase. Each Fund may write put and call options along with a long position in options to increase its ability to hedge against a change in the market value of the securities it holds or is committed to purchase. Investments in futures contracts and other investments that contain leverage may require each Fund to maintain liquid assets. Generally, each Fund maintains an amount of liquid assets equal to its obligations relative to the position involved, adjusted daily on a marked-to-market basis. With respect to futures contracts that are contractually required to “cash-settle,” each Fund maintains liquid assets in an amount at least equal to each Fund’s daily marked-to-market obligation ( i.e. , each Fund’s daily net liability, if any), rather than the contracts’ notional value. By maintaining assets equal to its net obligation under cash-settled futures contracts, the Fund may employ leverage to a greater extent than if each Fund set aside assets equal to the futures contracts’ full notional value. Each Fund bases its asset maintenance policies on methods permitted by the staff of the SEC and may modify these policies in the future to comply with any changes in the guidance articulated from time to time by the SEC or its staff.

Options on Futures Contracts. An option on a futures contract, as contrasted with the direct investment in such a contract, gives the purchaser the right, in return for the premium paid, to assume a position in the underlying futures contract at a specified exercise price at any time prior to the expiration date of the option. Upon exercise of an option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account that represents the amount by which the market price of the futures contract exceeds (in the case of a call) or is less than (in the case of a put) the exercise price of the option on the futures contract. The potential for loss related to the purchase of an option on a futures contract is limited to the premium paid for the option plus transaction costs. Because the value of the option is fixed at the point of sale, there are no daily cash payments by the purchaser to reflect changes in the value of the underlying contract; however, the value of the option changes daily and that change would be reflected in the NAV of each Fund. The potential for loss related to writing call options is unlimited. The potential for loss related to writing put options is limited to the agreed upon price per Share, also known as the strike price, less the premium received from writing the put.

Each Fund may purchase and write put and call options on futures contracts that are traded on an exchange as a hedge against changes in value of its portfolio securities, or in anticipation of the purchase of securities, and may enter into closing transactions with respect to such options to terminate existing positions. There is no guarantee that such closing transactions can be affected.

Upon entering into a futures contract, a Fund will be required to deposit with the broker an amount of cash or cash equivalents known as “initial margin,” which is in the nature of a performance bond or good faith deposit on the contract and is returned to each Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to the expiration of a futures contract, each Fund may elect to close the position by taking an opposite position, which will operate to terminate a Fund’s existing position in the contract.

Restrictions on the Use of Futures Contracts and Options on Futures Contracts. Pursuant to a claim for exclusion filed with the National Futures Association (“NFA”) on behalf of each Fund, the Trust is not deemed to be a “commodity pool operator” (“CPO”), under the CEA, and it is not subject to registration or regulation as such under the CEA. The Investment Adviser is not deemed to be a “commodity trading advisor” with respect to its services as an investment adviser to each Fund. In February 2012, the CFTC adopted certain regulatory changes that may subject the Investment Adviser to register with the CFTC as CPO if a Fund is unable to comply with certain trading and marketing limitations on its investments in futures and certain other instruments. With respect to investments in swap transactions, commodity futures, commodity options or certain other derivatives used for purposes other than bona fide hedging purposes, the Trust, on behalf of each Fund must meet one of the following tests under the amended regulations in order to claim an exclusion from the definition of a CPO. First, the aggregate initial margin and premiums required to establish a Fund’s positions in such investments may not exceed five percent of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such investments). Alternatively, the aggregate net notional value of such instruments, determined at the time of the most recent position established, may not exceed one hundred percent (100%) of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). In addition to meeting one of the foregoing trading limitations, a Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the commodity futures, commodity options or swaps and derivatives markets. In the event that the Investment Adviser is required to register as a CPO with respect to a Fund, the disclosure and operations of the Fund would need to comply with all applicable CFTC regulations. Compliance with these additional registration and regulatory requirements could increase operational expenses. Other potentially adverse regulatory initiatives could also develop.

11

Swap Agreements. Over-the-counter (“OTC”) swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make periodic payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be performed on a net basis, with each Fund receiving or paying only the net amount of the two payments. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of liquid assets having an aggregate value at least equal to the accrued excess will be maintained by each Fund. Cleared swap agreements are contracts in which payments are guaranteed by a central clearinghouse.

The use of interest-rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

A Fund may be required to cover its potential economic exposure to certain derivatives transactions by holding an offsetting financial position and/or earmarking or segregating cash or liquid assets equal in value to a Fund’s potential economic exposure under the transaction. A Fund will cover such transactions as described herein or in such other manner in accordance with applicable laws and regulations. Assets used to cover derivatives transactions cannot be sold while the derivatives position is open, unless they are replaced by other appropriate assets. Earmarked or segregated cash or liquid assets and assets held in margin accounts are not otherwise available to a Fund for investment purposes. If a large portion of a Fund’s assets are used to cover derivatives transactions or are otherwise earmarked or segregated, it could affect portfolio management or a Fund’s ability to meet redemption requests or other current obligations. With respect to derivatives which are cash-settled (i.e., have no physical delivery requirement), a Fund is permitted to set aside liquid assets in an amount equal to a Fund’s daily marked-to-market net obligations (i.e., a Fund’s daily net liability) under the derivative, if any, rather than the derivative’s full notional value or the market value of the instrument underlying the derivative, as applicable. By setting aside assets equal to only its net obligations under cash-settled derivatives, a Fund will have the ability to employ leverage to a greater extent than if a Fund were required to segregate assets equal to the full notional amount of the derivative or the market value of the underlying instrument, as applicable.

Specific Risks Applicable to the db X-trackers Managed Municipal Bond Fund

Municipal Securities Risk. The market for municipal bonds may be less liquid than for taxable bonds. There may also be less information available on the financial condition of issuers of municipal securities than for public corporations. This means that it may be harder to buy and sell municipal securities, especially on short notice, and municipal securities may be more difficult for the Fund to value accurately than securities of public corporations. Since the Fund invests a significant portion of its portfolio in municipal securities, the Fund’s portfolio may have greater exposure to liquidity risk than a fund that invests in non-municipal securities.

Municipal securities may include revenue bonds, which are generally backed by revenue from a specific project or tax. The issuer of a revenue bond makes interest and principal payments from revenues generated from a particular source or facility, such as a tax on particular property or revenues generated from a municipal water or sewer utility or an airport. Revenue bonds generally are not backed by the full faith and credit and general taxing power of the issuer.

Some longer-term municipal securities give the investor the right to “put” or sell the security at par (face value) within a specified number of days following the investor’s request – usually one to seven days. This demand feature enhances a security’s liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, the Fund would hold the longer-term security, which could experience substantially more volatility.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal securities market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Available information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

12

Lease Obligations Risk. Lease obligations may have risks not normally associated with general obligation or other revenue bonds. Leases and installment purchase or conditional sale contracts (which may provide for title to the leased asset to pass eventually to the issuer) have developed as a means for governmental issuers to acquire property and equipment without the necessity of complying with the constitutional statutory requirements generally applicable for the issuance of debt. Certain lease obligations contain “non-appropriation” clauses that provide that the governmental issuer has no obligation to make future payments under the lease or contract unless money is appropriated for that purpose by the appropriate legislative body on an annual or other periodic basis. Consequently, continued lease payments on those lease obligations containing “non-appropriation” clauses are dependent on future legislative actions. If these legislative actions do not occur, the holders of the lease obligation may experience difficulty in exercising their rights, including disposition of the property.

Tobacco Bond Risk. Tobacco settlement revenue bonds are generally neither general nor legal obligations of a state or any of its political subdivisions and neither the faith and credit nor the taxing power nor any other assets or revenues of a state or of any political subdivision will be pledged to the payment of any such bonds. In addition, tobacco companies’ profits from the sale of tobacco products are inherently variable and difficult to estimate. There can be no guarantee that tobacco companies will earn enough revenues to cover the payments due under tobacco bonds.

Education Bond Risk. In general, there are two types of education-related bonds: those issued to finance projects for public and private colleges and universities, and those representing pooled interests in student loans. Bonds issued to supply educational institutions with funds are subject to the risk of unanticipated revenue decline, primarily the result of decreasing student enrollment or decreasing state and federal funding. Among the factors that may lead to declining or insufficient revenues are restrictions on students’ ability to pay tuition, availability of state and federal funding, and general economic conditions. Student loan revenue bonds are generally offered by state (or substate) authorities or commissions and are backed by pools of student loans. Underlying student loans may be guaranteed by state guarantee agencies and may be subject to reimbursement by the United States Department of Education through its guaranteed student loan program. Others may be private, uninsured loans made to parents or students which are supported by reserves or other forms of credit enhancement. Recoveries of principal due to loan defaults may be applied to redemption of bonds or may be used to re-lend, depending on program latitude and demand for loans. Cash flows supporting student loan revenue bonds are impacted by numerous factors, including the rate of student loan defaults, seasoning of the loan portfolio and student repayment deferral periods of forbearance. Other risks associated with student loan revenue bonds include potential changes in federal legislation regarding student loan revenue bonds, state guarantee agency reimbursement and continued federal interest and other program subsidies currently in effect.

Electric Utilities Bond Risk . The electric utilities industry has been experiencing, and will continue to experience, increased competitive pressures. Federal legislation in the last two years may open transmission access to any electricity supplier, although it is not presently known to what extent competition will evolve. Other risks include: (a) the availability and cost of fuel; (b) the availability and cost of capital; (c) the effects of conservation on energy demand; (d) the effects of rapidly changing environmental, safety and licensing requirements, and other federal, state and local regulations, (e) timely and sufficient rate increases; and (f) the effects of opposition to nuclear power.

Housing Bond Risk. Housing revenue bonds are generally issued by a state, county, city, local housing authority or other public agency. They generally are secured by the revenues derived from mortgages purchased with the proceeds of the bond issue. It is extremely difficult to predict the supply of available mortgages to be purchased with the proceeds of an issue or the future cash flow from the underlying mortgages. Consequently, there are risks that proceeds will exceed supply, resulting in early retirement of bonds, or that homeowner repayments will create an irregular cash flow. Many factors may affect the financing of multi-family housing projects, including acceptable completion of construction, proper management, occupancy and rent levels, economic conditions and changes to current laws and regulations.

Transportation Bond Risk. Transportation debt may be issued to finance the construction of airports, toll roads, highways or other transit facilities. Airport bonds are dependent on the general stability of the airline industry and on the stability of a specific carrier who uses the airport as a hub. Air traffic generally follows broader economic trends and is also affected by the price and availability of fuel. Toll road bonds are also affected by the cost and availability of fuel as well as toll levels, the presence of competing roads and the general economic health of an area. Fuel costs and availability also affect other transportation-related securities, as do the presence of alternate forms of transportation, such as public transportation.

13

Water and Sewer Bond Risk. Water and sewer revenue bonds are often considered to have relatively secure credit as a result of their issuer’s importance, monopoly status and generally unimpeded ability to raise rates. Despite this, lack of water supply due to insufficient rain, run-off or snow pack is a concern that has led to past defaults. Further, public resistance to rate increases, costly environmental litigation, and federal environmental mandates are challenges faced by issuers of water and sewer bonds.

Industrial Development Bond Risk. Industrial developments bonds are revenue bonds issued by or on behalf of public authorities to obtain funds to finance various public and/or privately operated facilities, including those for business and manufacturing, housing, sports, pollution control, airport, mass transit, port and parking facilities. These bonds are normally secured only by the revenues from the project and not by state or local government tax payments. Consequently, the credit quality of these securities is dependent upon the ability of the user of the facilities financed by the bonds and any guarantor to meet its financial obligations. These bonds are subject to a wide variety of risks, many of which relate to the nature of the specific project. Generally, the value and credit quality of these bonds are sensitive to the risks related to an economic slowdown.

Resource Recovery Risk. Resource recovery bonds are a type of revenue bond issued to build facilities such as solid waste incinerators or waste-to-energy plants. Typically, a private corporation is involved, at least during the construction phase, and the revenue stream is secured by fees or rents paid by municipalities for use of the facilities. The viability of a resource recovery project, environmental protection regulations, and project operator tax incentives may affect the value and credit quality of resource recovery bonds.

Special Tax Bond Risk. Special tax bonds are usually backed and payable through a single tax, or series of special taxes such as incremental property taxes. The failure of the tax levy to generate adequate revenue to pay the debt service on the bonds may cause the value of the bonds to decline.

Health Care Bond Risk. The health care industry is subject to regulatory action by a number of private and governmental agencies, including federal, state and local governmental agencies. A major source of revenues for the health care industry is payments from Medicare and Medicaid programs. As a result, the industry is sensitive to legislative changes and reductions in governmental spending for such programs. Numerous other factors may also affect the health care industry, as well as the value and credit quality of health care bonds, such as general and local economic conditions, demand for services, expenses (including malpractice insurance premiums) and competition among health care providers. In the future, the following elements may adversely affect health care facility operations: implementation of a national health insurance program; other state or local health care reform measures; medical and technological advances which dramatically alter the need for health services or the way in which such services are delivered; changes in medical coverage which alter the traditional fee-for-service revenue stream; and efforts by employers, insurers, and governmental agencies to reduce the costs of health insurance and health care services.

Tax Risks. As with any investment, you should consider how your investment in Shares of the Fund will be taxed. The tax information in the Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares of the Fund.

There is no guarantee that the Fund’s income will be exempt from federal or state income taxes. Events occurring after the date of issuance of a municipal bond or after the Fund’s acquisition of a municipal bond may result in a determination that interest on that bond is includible in gross income for U.S. federal income tax purposes retroactively to its date of issuance. Such a determination may cause a portion of prior distributions by the Fund to its shareholders to be taxable to those shareholders in the year of receipt. Federal or state changes in income or alternative minimum tax (“AMT”) rates or in the tax treatment of municipal bonds may make municipal bonds less attractive as investments and cause them to lose value.

Municipal Market Disruption Risk. The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of a bankruptcy. Proposals to restrict or eliminate the federal income tax exemption for interest on municipal securities are introduced before Congress from time to time. Proposals also may be introduced before state legislatures that would affect the state tax treatment of a municipal fund’s distributions. If such proposals were enacted, the availability of municipal securities and the value of a municipal fund’s holdings would be affected. Municipal bankruptcies are relatively rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear and remain untested. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state. These legal uncertainties could affect the municipal securities market generally, certain specific segments of the market, or the relative credit quality of particular securities. There is also the possibility that as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations

14

may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of the Fund’s municipal securities in the same manner. Any of these effects could have a significant impact on the prices of some or all of the municipal securities held by the Fund.

Proxy Voting

The Board has delegated responsibility for decisions regarding proxy voting for securities held by each Fund to the Sub-Adviser. The Sub-Adviser votes such proxies in accordance with its proxy policies and procedures, which are summarized in Appendix A to this SAI. The Board will periodically review each Fund’s proxy voting record.

Information with respect to how the Sub-Adviser voted proxies relating to the Funds’ portfolio securities during the 12-month period ended June 30 will be available: (i) without charge, upon request, by calling 1-855-329-3837 (1-855-DBX-ETFS); and (ii) on the SEC’s website at www.sec.gov.

Portfolio Holdings Information

The Trust has adopted a policy regarding the disclosure of information about the Trust’s portfolio holdings. The Board must approve all material amendments to this policy.

The Funds’ portfolio holdings are publicly disseminated each day the Funds are open for business through financial reporting and news services, including publicly accessible Internet web sites. In addition, a basket composition file, which includes the security names and share quantities to deliver in exchange for Fund Shares, together with estimates and actual cash components, is publicly disseminated daily prior to the opening of the Exchanges via the National Securities Clearing Corporation (“NSCC”). The basket represents one Creation Unit of each Fund. The Trust, the Adviser and the Administrator will not disseminate non-public information concerning the Trust.

Investment Limitations

The Board has adopted as non-fundamental policies the investment objectives of the Funds discussed in this SAI. Therefore, each of these Funds may change its investment objective without a Shareholder vote. The Board has adopted as fundamental policies for each Fund set forth below investment restrictions numbered 1 through 6 below. The restrictions for each Fund cannot be changed without the approval of the holders of a majority of that Fund’s outstanding voting securities. A vote of a majority of the outstanding voting securities is defined in the 1940 Act as the lesser of (a) 67% or more of the voting securities present at a fund meeting, if the holders of more than 50% of the outstanding voting securities are present or represented by proxy, and (b) more than 50% of outstanding voting securities.

Each Fund will not:

1.        Borrow money, except that (i) each Fund may borrow from banks for temporary or emergency (not leveraging) purposes, including the meeting of redemption requests which might otherwise require the untimely disposition of securities, and (ii) each Fund may, to the extent consistent with its investment policies, enter into repurchase agreements, reverse repurchase agreements, forward roll transactions and similar investment strategies and techniques; to the extent that it engages in transactions described in (i) and (ii), each Fund will be limited so that no more than 33 1/3% of the value of its total assets (including the amount borrowed) is derived from such transactions. Any borrowings which come to exceed this amount will be reduced in accordance with applicable law;

2.        Issue any senior security, except as permitted under the 1940 Act, as amended, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time;

3.        Make loans, except as permitted under the 1940 Act, as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time;

15

4.        Purchase or sell real estate unless acquired as a result of ownership of securities or other investments (but this restriction shall not prevent each Fund from investing in securities of companies engaged in the real estate business or securities or other instruments backed by real estate or mortgages), or commodities or commodity contracts (but this restriction shall not prevent each Fund from trading in futures contracts and options on futures contracts, including options on currencies to the extent consistent with the Fund’s investment objectives and policies); or

5.        Engage in the business of underwriting securities issued by other persons, except to the extent that each Fund may technically be deemed to be an underwriter under the 1933 Act, the disposing of portfolio securities.

2.        Purchase securities on margin, except that the Fund may obtain such short-term credits as are necessary for the clearance of transactions; and provided that margin deposits in connection with futures contracts, options on futures contracts or other derivative instruments shall not constitute purchasing securities on margin;

3.        Purchase securities of open-end or closed-end investment companies except in compliance with the 1940 Act, although the Fund may not acquire any securities of registered open-end investment companies or registered unit investment trusts in reliance on Sections 12(d)(1)(F) or 12(d)(1)(G) of the 1940 Act;

4.        Invest in direct interests in oil, gas or other mineral exploration programs or leases; however, the Fund may invest in the securities of issuers that engage in these activities); and
