Ticker: RVNU

Stock Exchange: NYSE Arca, Inc.

Investment Objective

The fund seeks investment results that correspond generally to the performance, before fees and expenses, of the Solactive Municipal Infrastructure Revenue Bond Index.

Fees and Expenses

These are the fees and expenses that you will pay when you buy, hold and sell shares. You may also pay other fees, such as brokerage commissions and other fees to financial intermediaries on the purchase and sale of shares of the fund, which are not reflected in the table and example below.

ANNUAL FUND OPERATING EXPENSES
(expenses that you pay each year as a % of the value of your investment) 

Management fee	0.15
Other Expenses	None
Total annual fund operating expenses	0.15

EXAMPLE

This Example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. The Example does not take into account brokerage commissions that you may pay on your purchases and sales of shares of the fund. It also does not include the transaction fees on purchases and redemptions of Creation Units (defined herein), because those fees will not be imposed on retail investors. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 

	1 Year	3 Years	5 Years	10 Years
	$15	$48	$85	$192

PORTFOLIO TURNOVER 

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 18% of the average value of its portfolio.

Principal Investment Strategies

The fund, using a "passive" or indexing investment approach, seeks investment results that correspond generally to the performance, before fees and expenses, of the Solactive Municipal Infrastructure Revenue Bond Index (the "Underlying Index"), which is designed to track the performance of the US long-term tax exempt bond market, consisting of infrastructure revenue bonds. The fund uses a representative sampling indexing strategy in seeking to track the Underlying Index, meaning that it will generally invest in a sample of securities in the index whose risk, return and other characteristics resemble the risk, return and other characteristics of the Underlying Index as a whole. The fund will invest at least 80% of its total assets (but typically far more) in instruments that comprise the Underlying Index. Due to regulatory changes, effective June 11, 2026, the fund will replace this 80% investment policy and related disclosures set forth in this prospectus. Specifically, effective June 11, 2026, under normal circumstances, the fund will invest at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in component securities of the Underlying Index.

The Underlying Index is comprised of tax-exempt municipal securities issued by states, cities, counties, districts, their respective agencies, and other tax-exempt issuers. The Underlying Index is intended to track bonds that have been issued with the intention of funding federal, state and local infrastructure projects, such as water and sewer systems, public sewer systems, toll roads, bridges, tunnels and many other public use projects.

As of July 31, 2025, the Underlying Index consisted of 779 securities (181 issuers) with an average amount outstanding of approximately $92 million and a minimum amount outstanding of approximately $9 million. The Underlying Index is a total return index, which assumes that any cash distributions are reinvested back into the Underlying Index.

The Underlying Index is designed to only hold those bonds issued by state and local municipalities where the interest and principal repayments are generated from dedicated revenue streams or double-barreled entities (whose bonds are backed by both a dedicated revenue stream and a general obligation pledge).

The Underlying Index may include private activity bonds, industrial development bonds, special tax bonds and transportation bonds.

Private activity bonds are issued by municipalities and other public authorities to finance development of industrial facilities for use by a private enterprise. The private enterprise pays the principal and interest on the bond, and the issuer does not pledge its full faith, credit and taxing power for repayment.

Industrial development bonds are a specific type of revenue bond backed by the credit and security of a private user and therefore have more potential risk. The interest from industrial development bonds, when distributed by the fund as "exempt-interest dividends" to shareholders, may be subject to the US federal alternative minimum tax applicable to individuals ("AMT").

Special tax bonds are payable for and secured by the revenues derived by a municipality from a particular tax (e.g., tax on the rental of a hotel room, on the purchase of food and beverages, on the rental of automobiles or on the consumption of liquor). Special tax bonds are not secured by the general tax revenues of the municipality, and they do not represent general obligations of the municipality.

Transportation bonds are obligations of issuers that own and operate public transit systems, ports, highways, turnpikes, bridges and other transportation systems.

In order to be eligible for inclusion in the Underlying Index, the municipal securities must be offered publicly; meet a minimum amount outstanding and deal amount; be investment-grade; have a fixed-rate coupon payment; and are not prefunded/escrowed to maturity. Municipal bonds which are subject to the AMT and state and local taxes are

eligible for inclusion in the Underlying Index. The Underlying Index does not attempt to achieve a particular duration (which is a measure of a bond's sensitivity to interest rates), but the Underlying Index limits eligibility for inclusion to municipal securities which have a stated final maturity of 10 years or longer and are not callable for at least the next 5 years. Under normal circumstances, the Underlying Index is reconstituted and rebalanced on a monthly basis. The fund changes its portfolio in accordance with the Underlying Index, and, therefore, any changes to the Underlying Index's reconstitution and rebalancing schedule will result in corresponding changes to the fund's schedule of portfolio changes. Any changes made to the Underlying Index in between scheduled reconstitutions and rebalancings (e.g., in the event of a corporate action) also will result in corresponding changes to the fund's portfolio.

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 and its territories which are classified as "municipal infrastructure revenue" bonds based on the Underlying Index's criteria summarized above, whose income is free from regular federal income tax. Because municipal securities that pay interest subject to the AMT may be included in the Underlying Index without limit, the fund may invest an unlimited amount of its net assets in municipal securities whose income is subject to the AMT.

As of July 31, 2025, a significant percentage of the Underlying Index was comprised of municipal securities of issuers in New York and California.

The fund will concentrate its investments (i.e., hold 25% or more of its total assets) in a particular industry or group of industries to the extent that its Underlying Index is concentrated. The fund's exposure to particular sectors may change over time to correspond to changes in the Underlying Index.

The Underlying Index is sponsored by Solactive AG ("Solactive" or "Index Provider"), which is independent of the fund and the Advisor. The Index Provider develops the Underlying Index methodology and determines the composition and relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index. The fund is not sponsored, endorsed, sold or promoted by Solactive.

Main Risks

As with any investment, you could lose all or part of your investment in the fund, and the fund's performance could trail that of other investments. The fund is subject to the main risks noted below, any of which may adversely affect the fund's net asset value ("NAV"), trading price, yield, total return and ability to meet its investment objective, as well as other risks that are described in greater detail in

Summary Prospectus October 1, 2025

the section of this Prospectus entitled "Additional Information About Fund Strategies, Underlying Index Information and Risks" and in the Statement of Additional Information ("SAI"). An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

Municipal securities risk. Municipal instruments may be susceptible to periods of economic stress, which could affect the market values and marketability of many or all municipal obligations of issuers in a state, U.S. territory, or possession. Municipal securities are subject to the risk that litigation, legislation or other political events, local business or economic conditions or the bankruptcy of the issuer could have a significant effect on an issuer's ability to make payments of principal and/or interest. Certain municipalities may have difficulty meeting their obligations due to, among other reasons, changes in underlying demographics. Municipal securities can be significantly affected by political changes as well as uncertainties in the municipal market related to taxation, legislative changes or the rights of municipal security holders. Because many municipal securities are issued to finance similar projects, especially those relating to education, health care, transportation, utilities and water and sewer, conditions in those sectors can affect the overall municipal market. In addition, changes in the financial condition of an individual municipal issuer can affect the overall municipal market. 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. The market for municipal bonds may be less liquid than for taxable bonds. There may be less information available on the financial condition of issuers of municipal securities than for public corporations.

Municipal securities may also have exposure to potential physical risks resulting from climate change, including extreme weather, flooding and fires. Climate risks, if they materialize, can adversely impact a municipal issuer's financial plans in current or future years or may impair a facility or other source generating revenues backing a municipal issuer's revenue bonds. As a result, the impact of climate risks may adversely impact the value of the fund's shares.

Market disruption risk. Economies and financial markets throughout the world have become increasingly interconnected, which has increased the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. This includes reliance on global supply chains that are susceptible to disruptions resulting from, among other things, war

and other armed conflicts, tariffs, extreme weather events, and natural disasters. Such supply chain disruptions can lead to, and have led to, economic and market disruptions that have far-reaching effects on financial markets worldwide. The value of the fund's investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, debt levels and credit ratings, and trade policies, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets. In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty or financial crises, contagion, tariffs and trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, government shutdowns, public health crises, natural disasters, supply chain disruptions, climate change and related events or conditions, have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.

Current military and other armed conflicts in various geographic regions, including those in Europe and the Middle East, can lead to, and have led to, economic and market disruptions, which may not be limited to the geographic region in which the conflict is occurring. Such conflicts can also result, and have resulted in some cases, in sanctions being levied by the United States, the European Union and/or other countries against countries or other actors involved in the conflict. In addition, such conflicts and related sanctions can adversely affect regional and global energy, commodities, financial and other markets and thus could affect the value of the fund's investments. The extent and duration of any military conflict, related sanctions and resulting economic and market disruptions are impossible to predict, but could be substantial.

Other market disruption events include pandemic spread of viruses, such as the novel coronavirus known as COVID-19, which have caused significant uncertainty, market volatility, decreased economic and other activity, increased government activity, including economic stimulus measures, and supply chain disruptions, and may adversely affect the fund and its investments.

Summary Prospectus October 1, 2025

In addition, markets are becoming increasingly susceptible to disruption events resulting from the use of new and emerging technologies to engage in cyber-attacks or to take over the websites and/or social media accounts of companies, governmental entities or public officials, or to otherwise pose as or impersonate such, which then may be used to disseminate false or misleading information that can cause volatility in financial markets or for the securities of a particular company, group of companies, industry or other class of assets.

Adverse market conditions or particular market disruptions, such as those discussed above, may magnify the impact of each of the other risks described in this "MAIN RISKS" section and may increase volatility in one or more markets in which the fund invests leading to the potential for greater losses for the fund.

Inflation risk. Inflation risk is the risk that the real value of certain assets or real income from investments (the value of such assets or income after accounting for inflation) will be less in the future as inflation decreases the value of money. Inflation, and investors' expectation of future inflation, can impact the current value of the fund's portfolio, resulting in lower asset values and losses to shareholders. This risk may be elevated compared to historical market conditions and could be impacted by monetary policy measures and the current interest rate environment.

Fixed income securities risk. Fixed-income securities are subject to the risk of the issuer's inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity, market perception of the creditworthiness of the issuer, willingness of broker-dealers and other market participants to make markets in the applicable securities, and general market liquidity (i.e., market risk). Lower rated fixed-income securities have greater volatility because there is less certainty that principal and interest payments will be made as scheduled. There is a risk that a lack of liquidity or other adverse credit market conditions may hamper the fund's ability to sell the debt securities in which it invests or to find and purchase debt instruments included in the Underlying Index.

Private activity bonds risk. The issuers of private activity bonds in which the fund may invest may be negatively impacted by conditions affecting either the general credit of the user of the private activity project or the project itself. The fund's private activity bond holdings also may pay interest subject to the AMT. See "Taxes" for more details.

Industrial development bond risk. These revenue bonds are 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. Payment of interest on and repayment of principal on such bonds are the responsibility of the user and/or any guarantor. 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.

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. Adverse conditions and developments affecting a particular project may result in lower revenues to the issuer of the municipal securities, which may adversely affect the value of the fund's portfolio.

Transportation bond risk. Transportation bonds 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. Municipal securities that are issued to finance a particular transportation project often depend solely on revenues from that project to make principal and interest payments. Adverse conditions and developments affecting a particular project may result in lower revenues to the issuer of the municipal securities.

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 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.

Interest rate risk. When interest rates rise, prices of debt securities generally decline. The longer the duration of the fund's debt securities, the more sensitive the fund will be to interest rate changes. (As a general rule, a 1% rise in interest rates means a 1% fall in value for every year of duration.) Interest rates can change in response to the supply and demand for credit, government and/or central bank monetary policy and action, inflation rates and other factors. Changes in monetary policy made by central banks

Summary Prospectus October 1, 2025

or governments are likely to affect the level of interest rates. Changing interest rates may have unpredictable effects on markets, may result in heightened market volatility and potential illiquidity and may detract from fund performance to the extent the fund is exposed to such interest rates and/or volatility. Rising interest rates could cause the value of the fund's investments - and therefore its share price as well - to decline. A rising interest rate environment may cause investors to move out of fixed-income securities and related markets on a large scale, which could adversely affect the price and liquidity of such securities and could also result in increased redemptions from the fund.

Credit risk. The fund's performance could be hurt if an issuer of a debt security suffers an adverse change in financial condition that results in a payment default, security downgrade or inability to meet a financial obligation. Credit risk is greater for lower-rated securities. Because the issuers of junk bonds may be in uncertain financial health, the prices of their debt securities could be more vulnerable to bad economic news, or even the expectation of bad news, than investment-grade debt securities. Credit ratings may not be an accurate assessment of credit risk.

Geographic focus risk. To the extent that the Underlying Index and the fund are significantly comprised of issuers in a single state, region or sector of the municipal securities market, 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 the ability of a state, region or sector to repay its obligations.

Risks related to investing in New York. The fund may invest a significant portion of its assets in municipal obligations of issuers located in the State of New York and, therefore, will have greater exposure to negative political, economic, regulatory or other factors within the State of New York, including the financial condition of its public authorities and political subdivisions, than a fund that invests in a broader base of securities. Unfavorable developments in any economic sector may have a substantial impact on the overall New York municipal market. Certain issuers of New York municipal bonds have experienced serious financial difficulties in the past and reoccurrence of these difficulties may impair the ability of certain New York issuers to pay principal or interest on their obligations.

Risks related to investing in California. The fund may invest a significant portion of its assets in municipal obligations of issuers located in the State of California. While California's economy is broad, it does have major concentrations in high technology, manufacturing, entertainment, agriculture, tourism, construction and services, and may be sensitive to economic problems affecting those industries. Consequently, the fund may be affected by political,

economic, regulatory and other developments within California and by the financial condition of California's political subdivisions, agencies, instrumentalities and public authorities.

Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund's performance. The fund may become more focused in particular industries, asset classes or sectors of the economy as a result of changes in the valuation of the fund's investments or fluctuations in the fund's assets, and the fund is not required to reduce such exposures under these circumstances.

Prepayment and extension risk. When interest rates fall, issuers of high interest debt obligations may pay off the debts earlier than expected (prepayment risk), and the fund may have to reinvest the proceeds at lower yields. When interest rates rise, issuers of lower interest debt obligations may pay off the debts later than expected (extension risk), thus keeping the fund's assets tied up in lower interest debt obligations. Ultimately, any changes or unexpected behavior in interest rates could increase the volatility of the fund's share price and yield and could hurt fund performance.

Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment at an acceptable price. This risk can be ongoing for any security that does not trade actively or in large volumes, for any security that trades primarily on smaller markets, and for investments that typically trade only among a limited number of large investors (such as restricted securities). In unusual market conditions, even normally liquid securities may be affected by a degree of liquidity risk. This may affect only certain securities or an overall securities market.

Although the fund primarily seeks to redeem shares of the fund on an in-kind basis, if the fund is forced to sell underlying investments at reduced prices or under unfavorable conditions to meet redemption requests or other cash needs, the fund may suffer a loss or recognize a gain that may be distributed to shareholders as a taxable distribution. This may be magnified in a rising interest rate environment or other circumstances where redemptions from the fund may be higher than normal.

Tax risk. Income from municipal securities held by the fund could be declared taxable because of unfavorable changes in tax laws, adverse interpretations by the Internal Revenue Service or state tax authorities, or noncompliant conduct of a securities issuer. In such event, the value of such securities would likely fall, hurting fund performance, and shareholders may be required to pay additional taxes. In addition, because municipal securities that pay interest subject to the AMT may be included in the Underlying Index without limit, the fund may invest an unlimited

Summary Prospectus October 1, 2025

amount of its net assets in municipal securities whose income is subject to the AMT. Further, a portion of the fund's otherwise exempt-interest distributions may be taxable to those shareholders subject to the AMT.

Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods and the value determined for an investment may be materially different from the value realized upon such investment's sale.

Issuer-specific risk. The value of an individual security or particular type of security may be more volatile than the market as a whole and may perform differently from the value of the market as a whole.

Passive investing risk. Unlike a fund that is actively managed, in which portfolio management buys and sells securities based on research and analysis, the fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. Because the fund is designed to maintain a high level of exposure to the Underlying Index at all times, portfolio management generally will not buy or sell a security unless the security is added or removed, respectively, from the Underlying Index, and will not take any steps to invest defensively or otherwise reduce the risk of loss during market downturns.

Index-related risk. The fund seeks investment results that correspond generally to the performance, before fees and expenses, of the Underlying Index as published by the Index Provider. There is no assurance that the Index Provider will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. The Index Provider may cease publication of the Underlying Index or may terminate the license agreement allowing the fund to use the Underlying Index, either of which could have a material adverse effect on the fund. Market disruptions could cause delays in the Underlying Index's reconstitution and rebalancing schedule. During any such delay, it is possible that the Underlying Index and, in turn, the fund will deviate from the Underlying Index's stated methodology and therefore experience returns different than those that would have been achieved under a normal reconstitution and rebalancing schedule. Generally, the Index Provider does not provide any warranty, or accept any liability, with respect to the quality, accuracy or completeness of the Underlying Index or its related data, and does not guarantee that the Underlying Index will be in line with its stated methodology. Errors in the Underlying Index data, the Underlying Index computations and/or the construction of the Underlying Index in accordance with its stated methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the fund and its shareholders. The Advisor may have limited ability to detect such errors and neither the Advisor nor its affiliates provide any warranty or guarantee against such errors.

Therefore, the gains, losses or costs associated with the Index Provider's errors will generally be borne by the fund and its shareholders.

Tracking error risk. The fund may be subject to tracking error, which is the divergence of the fund's performance from that of the Underlying Index. The performance of the fund may diverge from that of the Underlying Index for a number of reasons, including operating expenses, transaction costs, cash flows and operational inefficiencies. The fund's return also may diverge from the return of the Underlying Index because the fund bears the costs and risks associated with buying and selling securities (especially when reconstituting or rebalancing the fund's securities holdings to reflect changes in the Underlying Index) while such costs and risks are not factored into the return of the Underlying Index. Transaction costs, including brokerage costs, will decrease the fund's NAV to the extent not offset by the transaction fee payable by an "Authorized Participant" ("AP"). Market disruptions and regulatory restrictions could have an adverse effect on the fund's ability to adjust its exposure in order to track the Underlying Index. Moreover, the use of a representative sampling investment approach (i.e., investing in a representative selection of securities included in the Underlying Index rather than all securities in the Underlying Index) may cause the fund's return to not be as well correlated with the return of the Underlying Index as would be the case if the fund purchased all of the securities in the Underlying Index in the proportions represented in the Underlying Index. In addition, the fund may not be able to invest in certain securities included in the Underlying Index, or invest in them in the exact proportions in which they are represented in the Underlying Index, due to government imposed legal restrictions or limitations, a lack of liquidity in the markets in which such securities trade, potential adverse tax consequences or other reasons. To the extent the fund calculates its net asset value based on fair value prices and the value of the Underlying Index is based on market prices (i.e., the value of the Underlying Index is not based on fair value prices), the fund's ability to track the Underlying Index may be adversely affected. Tracking error risk may be heightened during times of increased market volatility or other unusual market conditions. For tax purposes, the fund may sell certain securities, and such sale may cause the fund to recognize a taxable gain or a loss and deviate from the performance of the Underlying Index. In light of the factors discussed above, the fund's return may deviate significantly from the return of the Underlying Index.

Market price risk. Fund shares are listed for trading on an exchange and are bought and sold in the secondary market at market prices. The market prices of shares will fluctuate, in some cases materially, in response to changes in the NAV and supply and demand for shares. As a result, the trading prices of shares may deviate significantly from the NAV during periods of market volatility. The Advisor cannot predict whether shares will trade above, below or

Summary Prospectus October 1, 2025

at their NAV. Given the fact that shares can be created and redeemed in Creation Units (defined below), the Advisor believes that large discounts or premiums to the NAV of shares should not be sustained in the long-term. If market makers exit the business or are unable to continue making markets in fund shares, shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade shares in the secondary market). Further, while the creation/redemption feature is designed to make it likely that shares normally will trade close to the value of the fund's holdings, disruptions to creations and redemptions, including disruptions at market makers, APs or other market participants, or during periods of significant market volatility, may result in market prices that differ significantly from the value of the fund's holdings. Although market makers will generally take advantage of differences between the NAV and the market price of fund shares through arbitrage opportunities, there is no guarantee that they will do so. In addition, the securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund's shares trade. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads and the resulting premium or discount to the shares' NAV is likely to widen. If the markets for the fund's portfolio securities experience decreased liquidity, the trading markets for the fund's shares may also become less liquid with corresponding widening in the bid-ask spreads and differences between the market price and NAV of the fund's shares. Further, secondary markets may be subject to irregular trading activity, wide bid-ask spreads and extended trade settlement periods, which could cause a material decline in the fund's market price. The fund's investment results are measured based upon the daily NAV of the fund. Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by those APs creating and redeeming shares directly with the fund at NAV.

Operational and technology risk. Cyber-attacks, disruptions, or failures that affect the fund's service providers, index provider or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations. For example, the fund's or its service providers' or index provider's assets or sensitive or confidential information may be misappropriated, data may be corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund's net

asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund's operations.

While the fund and its service providers or index provider may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyber-attacks, disruptions or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will be effective. Among other situations, disruptions (for example, pandemics or health crises) that cause prolonged periods of remote work or significant employee absences at the fund's service providers or index provider could impact the ability to conduct the fund's operations. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, index provider, fund counterparties, issuers of securities held by the fund or other market participants.

Authorized Participant concentration risk. The fund may have a limited number of financial institutions that may act as Authorized Participants ("APs"). Only APs who have entered into agreements with the fund's distributor may engage in creation or redemption transactions directly with the fund (as described in the section of this Prospectus entitled "Buying and Selling Shares"). If those APs exit the business or are unable to process creation and/or redemption orders, (including in situations where APs have limited or diminished access to capital required to post collateral) and no other AP is able to step forward to create and redeem in either of these cases, shares may trade at a discount to NAV like closed-end fund shares and may even face delisting (that is, investors would no longer be able to trade shares in the secondary market).

Purchase and Sale of Fund Shares

The fund is an exchange-traded fund (commonly referred to as an "ETF"). Individual fund shares may only be purchased and sold through a brokerage firm. The price of fund shares is based on market price, and because ETF shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). The fund will only issue or redeem shares that have been aggregated into blocks of 50,000 shares or multiples thereof ("Creation Units") to APs who have entered into agreements with ALPS Distributors, Inc., the fund's distributor. You may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the fund (bid) and the lowest price a seller is willing to accept for shares of the fund (ask) when buying or selling shares (the "bid-ask spread"). Information on the fund's net asset value, market price, premiums and discounts and bid-ask spreads may be found at Xtrackers.com (the website does not form a part of this prospectus).

Tax Information

The fund intends to meet certain federal income tax requirements so that distributions of tax-exempt interest income will be treated as "exempt-interest dividends." These dividends are not subject to regular federal income tax. The fund may invest an unlimited amount of its net assets in municipal securities that generate interest income subject to the AMT. All exempt interest dividends may increase certain corporate shareholders' alternative minimum tax liability. The fund expects that its distributions will consist primarily of exempt-interest dividends. The fund's exempt-interest dividends may be subject to state and local taxes.

For more information regarding the tax consequences that may be associated with investing in the fund, please refer to the section of this Prospectus entitled "Taxes."

Payments to Broker-Dealers and
Other Financial Intermediaries

If you purchase shares of the fund through a broker-dealer or other financial intermediary (such as a bank), the Advisor or other related companies may pay the intermediary for marketing activities and presentations, educational training programs, the support of technology platforms and/or reporting systems or other services related to the sale or promotion of the fund. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
