² Pursuant to an Expense Limitation Agreement, the Adviser has contractually agreed to reimburse or waive fees and/or limit Fund expenses to the extent necessary to assure that the operating expenses of the Fund (exclusive of taxes, brokerage fees, commissions, and other transaction expenses, interest, and extraordinary expenses (such as litigation and indemnification expenses)) will not exceed 0.47% of the Fund’s average daily net assets per year until at least March 1, 2018. Pursuant to the Expense Limitation Agreement, the Fund (at a later date) may reimburse the Adviser for the fees it reimbursed or waived and/or limited pursuant to the Expense Limitation Agreement during any of the prior three fiscal years, provided that, among other things, reimbursement to be made to the Adviser does not cause Total Annual Fund Operating Expenses of the Fund to exceed 0.47% during the year in which it is paid and the Board of Trustees has approved such reimbursement to the Adviser.

Example: The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. This example does not take into account customary brokerage commissions that you pay when purchasing or selling Shares of the Fund in the secondary market. 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. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

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 rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. The Fund has not yet commenced operations as of the date of this Prospectus. Thus, no portfolio turnover information is provided for this Fund.

The Underlying Index is designed to measure the performance of U.S. listed companies that provide exposure to domestic infrastructure development, including companies involved in construction and engineering; production of infrastructure raw materials, composites and products; industrial transportation; and producers/distributors of heavy construction equipment (collectively, “U.S. Infrastructure Development Companies”),

The eligible universe of the Underlying Index includes the most liquid and investable companies in accordance with the standard market capitalization and liquidity criteria associated with developed markets, as defined by the Index Provider. As of March 1, 2017, companies must have a minimum market capitalization of $300 million and a minimum average daily turnover for the last 6 months greater than or equal to $1 million in order to be eligible for inclusion in the Underlying Index. The Underlying Index only includes companies listed in the United States.

From the eligible universe, the Index Provider identifies U.S. Infrastructure Development Companies by applying a proprietary analysis that consists of two primary components: theme identification and company analysis. As part of the theme identification process, the Index Provider analyzes industry reports, investment research and spending trends related to infrastructure development in order to establish the themes that are expected to provide the most exposure to increased investment in U.S. infrastructure. As of March 1, 2017, the Index Provider has identified the following four U.S. infrastructure development themes: (1) construction and engineering services, (2) infrastructure raw materials, composites and products, (3) construction equipment producers/distributors, and (4) industrial transportation (collectively, “U.S. Infrastructure Development Themes”).

In the second step of the process, companies are analyzed based on two primary criteria: revenue exposure and primary business operations. A company is eligible for inclusion in the Underlying Index if (i) according to a public filing, it generates a majority of its revenue from one of the U.S. Infrastructure Development Themes, or (ii) it has stated its primary business to be in products and services focused on one of the U.S. Infrastructure Development Themes. Furthermore, only companies that generate greater than 50% of revenues from the U.S. as of the index selection date are eligible for inclusion in the Underlying Index. Accordingly, the Fund assets will be concentrated (that is, it will hold 25% or more of its total assets) in companies that provide exposure to U.S. infrastructure development.

The Underlying Index is weighted according to a modified capitalization weighting methodology and is reconstituted and rebalanced annually. At the annual rebalance, a capping methodology is applied to reduce concentration in individual securities and increase diversification of the Underlying Index. The Underlying Index may include large-, mid- or small-capitalization companies, and components primarily include industrials and materials companies. The Fund's investment objective and Underlying Index may be changed without shareholder approval.

The Underlying Index is sponsored by the Index Provider, which is an organization that is independent of the Fund and Global X Management Company LLC, the investment adviser for the Fund (“Adviser”). The Index Provider determines the relative weightings of the securities in the Underlying Index and publishes information regarding the market value of the Underlying Index.

The Fund generally will use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Underlying Index in approximately the same proportions as in the Underlying Index. However, the Fund may utilize a representative sampling strategy with respect to the Underlying Index when a replication strategy might be detrimental or disadvantageous to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to replicate the Underlying Index, in instances in which a security in the Underlying Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Underlying Index.

The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Underlying Index, before fees and expenses, will exceed 95%. A correlation percentage of 100% would indicate perfect correlation. If the Fund uses a replication strategy, it can be expected to have greater correlation to the Underlying Index than if it uses a representative sampling strategy.

The Fund concentrates its investments (i.e., holds 25% or more of its total assets) in a particular industry or group of industries to approximately the same extent that the Underlying Index is concentrated. As of March 1, 2017, the Underlying Index was concentrated in the Industrials and Materials sectors.

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. There is no guarantee that the Fund will achieve its investment objective. The Fund is subject to the principal 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 the Additional Information About the Fund section of the Prospectus and in the Statement

Assets Under Management (AUM) Risk: From time to time an Authorized Participant, a third party investor, the Fund’s adviser or another affiliate of the Fund’s adviser or the Fund may invest in the Fund and hold its investment for a specific period of time in order to facilitate commencement of the Fund’s operations or for the Fund to achieve size or scale. There can be no assurance that any such entity would not redeem its investment or that the size of the Fund would be maintained at such levels which could negatively impact the Fund.

Authorized Participants Concentration Risk: The Fund has a limited number of financial institutions that may act as Authorized Participants. Only Authorized Participants who have entered into agreements with the Fund’s distributor may engage in creation or redemption transactions directly with the Fund. To the extent that those Authorized Participants exit the business or are unable to process creation and/or redemption orders, and no other Authorized Participant is able to step forward to create or redeem in either of those cases, Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts and/or delisting from an exchange.

Concentration Risk: Because the Fund's investments are concentrated in the industrials and materials sectors, the Fund will be susceptible to loss due to adverse occurrences affecting these sectors. To the extent that the Underlying Index concentrates in the securities of issuers in a particular country, industry, market, asset class, or sector, the Fund will also concentrate its investments to approximately the same extent. By concentrating its investments in a country, industry, market, asset class, or sector, the Fund faces more risks than if it were diversified broadly over numerous countries, industries, markets, asset classes, or sectors. Such risks, any of which may adversely affect the companies in which the Fund invests, may include, but are not limited to, the following: general economic conditions or cyclical market patterns that could negatively affect supply and demand; competition for resources, adverse labor relations, political or world events; obsolescence of technologies; and increased competition or new product introductions that may affect the profitability or viability of companies in a particular country, industry, market, asset class, or sector. In addition, at times, such country, industry, market, asset class, or sector may be out of favor and underperform other similar categories or the market as a whole. For additional details on these risks, please see Risks Related to Investing in the Industrials Sector and Risks Related to Investing in the Materials Sector.

Cyber Security Risk: Failures or breaches of the electronic systems of the Fund, the Fund's adviser, and the Fund's other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions and negatively impact the Fund's business operations, potentially resulting in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherit limitations in such plans and systems. Furthermore, the Fund cannot control the cyber security plans and systems of the Fund's service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests.

Index-Related Risk: There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations and/or the construction of the Underlying Index in accordance with its 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.

Large-Capitalization Companies Risk: Large-capitalization companies may trail the returns of the overall stock market. Large-capitalization stocks tend to go through cycles of doing better - or worse - than the stock market in general. These periods have, in the past, lasted for as long as several years.

include increasing interest rates, could cause increased volatility in financial markets and lead to higher levels of Fund redemptions, which could have a negative impact on the Fund. The Fund’s NAV could decline over short periods due to short-term market movements and over longer periods during market downturns.

Market Trading Risk: The Fund faces numerous market trading risks, including the potential lack of an active market for Shares, losses from trading in secondary markets, periods of high volatility and disruption in the creation/redemption process of the Fund. Any of these factors may lead to the Shares trading at a premium or discount to NAV.

Mid-Capitalization Companies Risk: Mid-capitalization companies may have greater price volatility, lower trading volume and less liquidity than large-capitalization companies. In addition, mid-capitalization companies may have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources and less competitive strength than large-capitalization companies.

Non-Diversification Risk: The Fund is classified as a “non-diversified” investment company under the Investment Company Act of 1940 ("1940 Act"). As a result, the Fund is subject to the risk that it will be more volatile than a diversified fund because the Fund may invest its assets in a smaller number of issuers or may invest a larger proportion of its assets in a single issuer. As a result, the gains and losses on a single investment may have a greater impact on the Fund’s NAV and may make the Fund more volatile than more diversified funds.

Operational Risk: The Fund is exposed to operational risk arising from a number of factors, including but not limited to human error, processing and communication errors, errors of the Fund's service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate for those risks that they are intended to address.

Passive Investment Risk: The Fund is not actively managed and the Adviser does not attempt to take defensive positions in declining markets. Unlike many investment companies, the Fund does not utilize an investing strategy that seeks returns in excess of its Underlying Index. Therefore, it would not necessarily buy or sell a security unless that security is added or removed, respectively, from the Underlying Index, even if that security generally is underperforming. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy.

Premium/Discount Risk: Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for Shares may result in Shares trading at a significant premium or discount to NAV. If a shareholder purchases Shares at a time when the market price is at a premium to the NAV or sells Shares at a time when the market price is at a discount to the NAV, the shareholder may sustain losses.

Risks Related to Investing in Infrastructure Development Companies: The Fund invests in infrastructure development companies, including companies involved in construction, engineering, production of raw materials, production and distribution of heavy construction equipment and industrial transportation. General risks of infrastructure development companies include the general state of the economy, intense competition, consolidation, domestic and international politics, and excess capacity. In addition, infrastructure development companies may also be significantly affected by overall capital spending levels (including both private and public sector spending), economic cycles, technical obsolescence, delays in modernization, labor relations and government regulations. Some infrastructure development companies may rely heavily on local, state or national government contracts, and are therefore subject to higher degrees of political risk and could be negatively impacted by changes in government policies or a deterioration in government balance sheets in the future.

Risks Related to Investing in the Industrials Sector: Companies in the industrials sector are subject to fluctuations in supply and demand for their specific product or service. The products of manufacturing companies may face product obsolescence due to rapid technological developments. Government regulation, world events and economic conditions affect the performance of companies in the industrials sector. Companies also may be adversely affected by environmental damage and product liability claims.

Risks Related to Investing in the Materials Sector: Investments in securities of companies in the materials sector are subject to changes in commodity prices, exchange rates, import controls and worldwide competition. At times, worldwide production of industrial materials has exceeded demand, leading to poor investment returns or outright losses. Issuers in the materials sector are at risk of depletion of resources, technological progress, labor relations, governmental regulations and environmental damage and product liability claims.

Tracking Error Risk: Tracking error is the divergence of the Fund's performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the Fund's portfolio and those included in the Underlying Index, pricing differences (including differences between a security's price at the local market close and the Fund's valuation of a security at the time

of calculation of the Fund's NAV), differences in transaction costs, the Fund's holding of uninvested cash, differences in timing of the accrual of or the valuation of dividends or interest, tax gains or losses, changes to the Underlying Index or the costs to the Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not. Index ETFs that are track indices with significant weight in emerging markets issuers may experience higher tracking error other than other index ETFs that do not track such indices.

Trading Halt Risk: An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Valuation Risk: The sales price the Fund could receive for a security may differ from the Fund’s valuation of the security and may differ from the value used by the Underlying Index, particularly for securities that trade in low value or volatile markets or that are valued using a fair value methodology. The value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's Shares.

The Fund does not have a full calendar year of performance. Once the Fund has completed a full calendar year of operations, a bar chart and table will be included that will provide some indication of the risks of investing in the Fund by showing the variability of the Fund's returns and comparing the Fund's performance to the Underlying Index. The Fund's performance is not necessarily indicative of how the Fund will perform in the future.

Shares of the Fund are or will be listed and traded at market prices on a national securities exchange. Shares may only be purchased and sold on the Exchange through a broker-dealer. The price of Shares is based on market price, and because ETF shares trade at market prices rather than at NAV, Shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). Only “Authorized Participants” (as defined in the SAI) who have entered into agreements with the Fund’s distributor, SEI Investments Distribution Co. ("Distributor"), may engage in creation or redemption transactions directly with the Fund. The Fund will only issue or redeem Shares that have been aggregated into blocks of 50,000 Shares or multiples thereof ("Creation Units"). The Fund will issue or redeem Creation Units in return for a basket of cash and/or securities that the Fund specifies each Business Day.

The Fund intends to make distributions that may be taxable to you as ordinary income or capital gains, unless you are investing through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement account ("IRA"), in which case distributions from such tax-deferred arrangements may be taxable to you.

The Adviser and its related companies may pay broker/dealers or other financial intermediaries (such as a bank) for the sale of Fund Shares and related services. These payments may create a conflict of interest by influencing your broker/dealer, sales persons or other intermediary or its employees or associated persons to recommend the Fund over another investment. Ask your financial adviser or visit your financial intermediary’s website for more information.
