U.S. GLOBAL JETS ETF SUMMARY

Investment Objective

The U.S. Global Jets ETF (the “Fund”) seeks to track the performance, before fees and expenses, of the U.S. Global Jets Index (the “Index”).

Fees and Expenses of the Fund

The following table describes the fees and expenses you may pay if you buy, hold, and sell shares of the Fund (“Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below.


Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees			0.60%
Distribution and/or Service (12b-1) Fees			None
Other Expenses			0.00%
Total Annual Fund Operating Expenses			0.60%

Expense 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 continue to hold or redeem 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. 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
$61	$192	$335	$750

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. For the fiscal year ended December 31, 2021, the Fund’s portfolio turnover rate was 54% of the average value of its portfolio.

Principal Investment Strategy

The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index is composed of the exchange-listed common stock (or depositary receipts) of U.S. and international passenger airlines, aircraft manufacturers, airports, terminal services companies, and airline-related internet media and services companies (e.g., websites for purchasing airline tickets), each as determined by independent industry listings (collectively, “Airline Companies”). The Index may include small-, mid-, and large-capitalization companies.

U.S. Global Jets Index

The Index tracks the performance of Airline Companies across the globe with an emphasis on domestic passenger airlines. The universe of Airline Companies is screened for investibility (e.g., must be listed on a securities exchange), a minimum market capitalization of $100 million, and liquidity (minimum average daily value traded). U.S. Global Investors, Inc., the Fund’s investment adviser (the “Adviser”), generally expects the Index to include 50 Airline Companies. The Index is rebalanced and reconstituted quarterly in March, June, September, and December.

At the time of each reconstitution of the Index, each of the four largest U.S. passenger airline companies, as measured primarily by their market capitalization and average dollar value traded and, to a lesser extent, their passenger load factor, receives a 10 percent weighting allocation of the Index. Each of the next eight largest U.S. or Canadian passenger airline companies receives a 3 percent weighting allocation of the Index.

The remaining Airline Companies meeting the Index criteria are then scored based on multiple fundamental factors. Their score is primarily driven by their cash flow return on invested capital (CFROIC) and average dollar value traded with additional inputs based on sales per share growth, gross margins, and sales yield. Each of the eight U.S. or Canadian companies with the highest composite scores receives a 2 percent weighting allocation of the Index, each of the 10 non-U.S. companies with the next highest composite

scores receives a 1 percent weighting allocation of the Index, and each of the 20 non-U.S. companies with the next highest composite scores receives a 0.5 percent weighting allocation of the Index.

The Index was developed by U.S. Global Indices, LLC (the “Index Provider”), a wholly-owned subsidiary of the Adviser, in 2015 in anticipation of the commencement of operations of the Fund and is constructed using an objective, rules-based methodology.

The Index calculation agent is Indxx, LLC, which is not affiliated with the Fund, the Adviser, the Index Provider, or the Fund’s distributor. The Index calculation agent provides information to the Fund about the constituents of the Index and does not provide investment advice with respect to the desirability of investing in, purchasing or selling securities.

The Fund’s Investment Strategy

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80 percent of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts).

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest in all of the component securities of the Index in approximately the same proportion as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).

The Fund generally may invest in securities or other investments not included in the Index, but which the Adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).

To the extent the Index concentrates (i.e., holds more than 25 percent of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Adviser expects that the Index, and consequently the Fund, will generally be concentrated in the securities of passenger airline companies.

Principal Investment Risks

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Funds.”

•Airline Companies Risk. Airline Companies may be adversely affected by a downturn in economic conditions that can result in decreased demand for air travel. Airline Companies may also be significantly affected by changes in fuel prices, which may be very volatile, the imposition of tariffs, and/or changes in labor relations and insurance costs. Airline Companies may also be highly dependent on aircraft or related equipment from a small number of suppliers, and consequently, issues affecting the availability, reliability, safety, or longevity of such aircraft or equipment (e.g., the inability of a supplier to meet aircraft demand or the grounding of an aircraft due to safety concerns) may have a significant effect on the operations and profitability of Airline Companies.

Airline Companies operating airline-related internet media and services face intense competition, which may have an adverse effect on profit margins. Such companies may have limited product lines, markets, financial resources, or personnel, and their products may face obsolescence due to rapid technological developments and frequent new product introduction. Such companies may face unpredictable changes in growth rates, competition for the services of qualified personnel, and competition from foreign competitors with lower production costs. Companies operating websites and other media may be heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect the profitability of these companies.

In addition, the Russian invasion of Ukraine and the resulting sanctions by Western countries on Russia, as well as retaliatory measures by Russia, may have a significant impact on Airline Companies. Bans on oil and energy imports from Russia by certain Western countries may increase the costs of jet fuel. In addition, certain Western nations have closed their airspace to all Russian aircraft, issued a recall of leased Russian aircraft and/or seized aircraft on leased aircraft located in Western airports. In response, Russia has closed its airspace to certain Western aircraft and Russia has seized certain leased aircraft located in Russia. These actions may lead to higher ticket prices, flight cancellations, longer routes, fewer diversion airports, a decreased demand for travel, and the permanent loss of property for Western companies. These and any related events could significantly and adversely affect the Fund’s performance and the value of an investment in the Fund.

•Concentration Risk. The Index, and consequently the Fund, is expected to concentrate its investments (i.e., hold more than 25% of its total assets) in the securities of passenger airline companies. As a result, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, the airline industry may be out of favor and underperform other industries or groups of industries or the market as a whole.

•Currency Exchange Rate Risk. The Fund’s assets may include investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

•Depositary Receipt Risk. Depositary Receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary Receipts listed on U.S. exchanges are issued by banks or trust companies and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in Depositary Receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the Depositary Receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

•Emerging Markets Risk. The Fund may invest in companies organized in emerging market nations. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments or investments in more developed international markets. Such conditions may impact the ability of the Fund to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Fund to decline in value. Less information may be available about companies in emerging markets than in developed markets because such emerging markets companies may not be subject to accounting, auditing and financial reporting standards or to other regulatory practices required by U.S. companies.

•Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers. In addition, local, regional or global events such as war, including Russia’s invasion of Ukraine, acts of terrorism, spread of infectious diseases or other public health issues, recessions, rising inflation, or other events could have a significant negative impact on the Fund and its investments. For example, the global pandemic caused by COVID-19, a novel coronavirus, and the aggressive responses taken by many governments, including closing borders, restricting international and domestic travel, and the imposition of prolonged quarantines or similar restrictions, has had negative impacts, and in many cases severe impacts, on markets worldwide. The COVID-19 pandemic has caused prolonged disruptions to the normal business operations of companies around the world and the impact of such disruptions is hard to predict. Such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Such events could adversely affect the prices and liquidity of the Fund’s portfolio securities or other instruments and could result in disruptions in the trading markets.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid-ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares, and this could lead to differences between the market price of the Shares and the underlying value of those Shares.

•Geographic Investment Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

•Non-Diversification Risk. The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance. However, the Fund intends to satisfy the diversification requirements for qualifying as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

•Passive Investment Risk. The Fund is not actively managed and the Adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology.

•Securities Lending Risk. The Fund may engage in securities lending. The Fund may lose money if the borrower of the loaned securities delays returning in a timely manner or fails to return the loaned securities. Securities lending involves the risk that the Fund could lose money in the event of a decline in the value of collateral provided for loaned securities. In addition, the Fund bears the risk of loss in connection with its investment of the cash collateral it receives from a borrower. To the extent that the value or return of the Fund’s investment of the cash collateral declines below the amount owed to the borrower, the Fund may incur losses that exceed the amount it earned on lending the security.

•Smaller Companies Risk. The Fund may invest in the securities of smaller-capitalization companies. As a result, the Fund may be more volatile than funds that invest in larger, more established companies. The securities of smaller-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Smaller-capitalization companies may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, its shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC.

•Tracking Error Risk. As with all index funds, the performance of the Fund and the Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Performance

The following performance information indicates some of the risks of investing in the Fund. The bar chart shows the Fund’s performance for calendar years ended December 31. The table illustrates how the Fund’s average annual returns for the 1-year, 5-year, and since inception periods compare with those of a broad measure of market performance and the Index. The Fund’s past performance, before and after taxes, does not necessarily indicate how it will perform in the future. Updated performance information is available on the Fund’s website at www.usglobaletfs.com.

Calendar Year Total Returns

During the period of time shown in the bar chart, the Fund’s highest quarterly return was 32.31% for the quarter ended December 31, 2020, and the lowest quarterly return was -53.46% for the quarter ended March 31, 2020.

Average Annual Total Returns

For the Periods Ended December 31, 2021


U.S. Global Jets ETF	1 Year	5 Years	Since Inception (4/28/2015)
Return Before Taxes	-5.05%	-4.71%	-1.81%
Return After Taxes on Distributions	-5.29%	-4.93%	-2.00%
Return After Taxes on Distributions and Sale of Shares	-2.97%	-3.49%	-1.34%
U.S. Global Jets Index (reflects no deduction for fees, expenses, or taxes)	-5.01%	-4.20%	-1.27%
S&P 500 Total Return Index (reflects no deduction for fees, expenses, or taxes)	28.71%	18.47%	15.14%

After-tax returns are calculated using the historical highest individual federal marginal income tax rates during the period covered by the table above and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their Shares through tax-deferred arrangements such as an individual retirement account (“IRA”) or other tax-advantaged accounts. In certain cases, the figure representing “Return After Taxes on Distributions and Sale of Shares” may be higher than the other return figures for the same period. A higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

Management

Investment Adviser

U.S. Global Investors, Inc. serves as investment adviser to the Fund.

Portfolio Managers

The Fund is managed by a team consisting of the following individuals: Frank E. Holmes, Chief Executive Officer and Director for the Adviser, has been a portfolio manager of the Fund since its inception in 2015. Ralph P. Aldis, CFA, a Portfolio Manager for the Adviser, has been a portfolio manager of the Fund since its inception in 2015.

Purchase and Sale of Shares

Shares are listed on the Exchange, and individual Shares may only be bought and sold in the secondary market through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only APs (typically, broker-dealers) may purchase or redeem. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities and/or a designated amount of U.S. cash.

Investors may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase Shares (bid) and the lowest price a seller is willing to accept for Shares (ask) when buying or selling Shares in the secondary market (the “bid-ask spread”). Recent information about the Fund, including its NAV, market price, premiums and discounts, and bid-ask spreads is available on the Fund’s website at www.usglobaletfs.com.

Tax Information

Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an IRA or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.

Portfolio Turnover

Principal Investment Strategy

The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index is composed of the exchange-listed common stock (or American Depositary Receipts (“ADRs”)) of U.S. and international (including emerging markets) companies that earn at least 50 percent of their aggregate revenue from precious metals (“Precious Metals Companies”). Precious metals consist of gold, silver, platinum, and palladium. The Index may include small-, mid-, and large-capitalization companies.

U.S. Global Go Gold and Precious Metal Miners Index

The Index universe consists of the common stock or ADRs of Precious Metals Companies across the globe that earn at least 50 percent of their aggregate revenue from precious metals through active (i.e., mining or production) or passive (i.e., owning royalties or production streams) means. The universe of Precious Metals Companies is screened for investibility (e.g., must be listed on a securities exchange) and liquidity (minimum average daily value traded). Precious Metals Companies that rely primarily on debt to finance their business are eliminated from the Index. To qualify for inclusion in the Index, Precious Metals Companies must have their common stock or a sponsored ADR listed on one of the following exchanges: Toronto Stock Exchange, TSX Venture, New York Stock Exchange (main market only), Nasdaq, London Stock Exchange (main market only), Hong Kong Stock Exchange, Johannesburg Stock Exchange, or Australian Securities Exchange. As described below, at the time of each rebalance of the Index, at least 30% of the Index will be allocated to Precious Metals Companies whose stock is listed on an exchange in the United States or Canada and that earn a majority of their revenue from gold and silver, and the top three such companies will each receive a 10% Index allocation.

The Index is composed of four “tiers” of Precious Metals Companies based on certain fundamental factors, their country of listing, and other criteria described in the table below. Each tier will first be populated with Precious Metals Companies having a gross margin of

at least 25% and whose business description includes the terms “royalty” or “streaming” (“Priority Companies”) before other Precious Metals Companies are eligible to be included in the Index. Each Precious Metals Company included in the Index universe receives a composite score based on multiple fundamental factors. Composite scores for Priority Companies are based on their revenue per employee, operating cash flow per employee, and gross margin, and scores for other companies are based primarily on their operating-cash-flow-to-enterprise-value ratio.


Tier 1 (30%)			The three highest-scoring Precious Metals Companies that (i) derive a majority of their revenue from silver or gold, (ii) have their common stock listed on an exchange in the United States or Canada, and (iii) have a market capitalization of at least $1 billion are individually weighted at 10%.
Tier 2 (20%)			The next five highest-scoring Precious Metals Companies that (i)(a) have their common stock listed on an exchange in the United States or Canada or (b) have a U.S.-listed ADR and have their common stock listed on an exchange in Australia, South Africa, or the United Kingdom, and (ii) have a market capitalization of at least $400 million are individually weighted at 4%.
Tier 3 (30%)			The next ten highest-scoring Precious Metals Companies that (i)(a) have their common stock listed on an exchange in the United States or Canada or (b) have a U.S.-listed ADR and have their common stock listed on an exchange in Australia, South Africa, or the United Kingdom, and (ii) have a market capitalization of at least $300 million are individually weighted at 3%.
Tier 4 (20%)			The next ten highest-scoring Precious Metals Companies that (i) have their common stock listed on an exchange outside of the United States or Canada and (ii) have a market capitalization of at least $200 million are individually weighted at 2%.

U.S. Global Investors, Inc., the Fund’s investment adviser (the “Adviser”), generally expects the Index to include approximately 28 Precious Metals Companies. The Index is rebalanced and reconstituted quarterly.

The Index was developed in 2017 by U.S. Global Indices, LLC (the “Index Provider”), a wholly-owned subsidiary of the Adviser, in anticipation of the commencement of operations of the Fund and is constructed using an objective, rules-based methodology.

The Fund’s Investment Strategy

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in Precious Metals Companies and at least 20% of its net assets (plus borrowings for investment purposes) in Precious Metals Companies that primarily derive their revenue from gold. The specific precious metals from which the Precious Metals Companies owned by the Fund derive their revenue may change over time, although the Adviser generally expects that the Fund will be predominantly invested in Precious Metals Companies that primarily derive their revenue from gold.

To the extent the Index has significant exposure to certain geographic regions, the Fund will have approximately the same exposure. The Adviser expects that the Index, and consequently the Fund, will generally have significant exposure to investments in South Africa, Australia, and Canada.

Principal Investment Risks

•Concentration Risk. The Index, and consequently the Fund, is expected to concentrate its investments (i.e., hold more than 25% of its total assets) in the securities of the metals and mining industry. As a result, the value of the Fund’s shares may rise and fall more than the value of shares of a fund that invests in securities of companies in a broader range of industries. In addition, at times, the metals and mining industry may be out of favor and underperform other industries or groups of industries or the market as a whole.

•Currency Exchange Rate Risk. The Fund invests primarily in investments denominated in non-U.S. currencies or in securities that provide exposure to such currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

•ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦Australia-Specific Risk. Because investments in the metals and mining industry may be geographically concentrated in Australian companies or companies that have a significant presence in Australia, investment results could be dependent on the financial condition of the Australian economy. Investments in Australian issuers may subject the Fund to regulatory, political, currency, security, and economic risk specific to Australia. The Australian economy is heavily dependent on exports from the agricultural and mining sectors. This makes the Australian economy susceptible to fluctuations in the commodity markets. Australia is also dependent on trading with key trading partners.

◦Canada-Specific Risk. Because investments in the metals and mining industry may be geographically concentrated in Canadian companies or companies that have a significant presence in Canada, investment results could be dependent on the financial condition of the Canadian economy. The Canadian economy is reliant on the sale of natural resources and commodities, which can pose risks such as the fluctuation of prices and the variability of demand for exportation of such products. Changes in spending on Canadian products by the economies of other countries or changes in any of these economies may cause a significant impact on the Canadian economy.

◦South Africa-Specific Risk. Because investments in the metals and mining industry may be geographically concentrated in South African companies or companies that have a significant presence in South Africa, investment results could be dependent on the financial condition of the South African economy. The securities markets in South Africa are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, currency devaluation, inflation, greater price fluctuations, adverse social and economic conditions in a neighboring country, natural disasters and environmental events, uncertainty regarding the existence of trading markets, governmental control, and heavy regulation of labor and industry. Additionally, the agriculture and mining sectors of South Africa’s economy account for a large portion of its exports, and thus the South African economy is susceptible to fluctuations in these commodity markets.

• Gold and Precious Metals Risk. The Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the metals and mining industry. Competitive pressures may have a significant effect on the financial condition of companies in such industry. Also, such companies are highly dependent on the price of certain precious metals. These prices may fluctuate substantially over short periods of time, so the Fund’s Share price may be more volatile than other types of investments. The prices of precious metals rise and fall in response to many factors, including: economic cycles; changes in inflation or expectations about inflation in various countries; interest rates; currency fluctuations; metal sales by governments, central banks, or international agencies; investment speculation; resource availability; fluctuations in industrial and commercial supply and demand; government regulation of the metals and materials industries; and government prohibitions or restrictions on the private ownership of certain precious and rare metals. The Index measures the performance of equity securities of Precious

Metals Companies and does not measure the performance of direct investment in precious metals. Consequently, the Fund’s Share price may not move in the same direction and to the same extent as the spot prices of precious metals.

•Portfolio Turnover Risk. The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

• Tax Risk. To qualify for the favorable tax treatment generally available to a RIC, the Fund must satisfy, among other requirements described in the SAI, certain diversification requirements. Given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Fund to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If the Fund were to fail to satisfy the diversification requirements, it could be eligible for relief provisions if the failure is due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. If the Fund were to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, its shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC.

Investment Objectives

Each Fund’s investment objective has been adopted as a non-fundamental investment policy and may be changed without shareholder approval upon written notice to shareholders.

U.S. Global Jets Index


Glossary Passenger Load Factor: The ratio of revenue passenger miles to available seat miles for an airline. Cash Flow Return On Invested Capital (CFROIC): A company’s net cash flow from operations divided by average invested capital. Average Dollar Value Traded: The volume of a company’s shares traded over the past 3 months multiplied by its last closing price. Sales Per Share Growth: A company’s last 12 months percent change in sales per share. Gross Margin: A company’s gross income, divided by net sales or revenue. Sales Yield: A company’s sales per share divided by its price per share.

An Airline Company is excluded from the Index if (i) its common stock is listed solely on a securities exchange in a country that does not allow the transfer of securities “free of payment” (e.g., Brazil, China, India, Russia, South Korea, Taiwan) and (ii) no depositary receipts for such company are listed on a securities exchange in a country other than those listed above.

At the time of each reconstitution of the Index, the minimum market capitalization and liquidity (minimum average daily value traded) are determined based on the aggregate net assets of investment products (including the Fund) tracking the Index. The minimum market capitalization increases from $100 million to $500 million if such products have net assets exceeding $1 billion. The minimum liquidity increases from $500,000 to $5 million if such products have net assets of $100 million to $1 billion and increases further to $10 million if such products have net assets of at least $1 billion.

U.S. Global Go Gold and Precious Metal Miners Index

Each company included in the U.S. Global Go Gold and Precious Metal Miners Index universe is scored based on multiple fundamental factors. The following definitions apply to the scoring criteria for Precious Metals Companies:

Gross Margin: A company’s sales revenue minus its cost of goods sold and depreciation, divided by sales revenue.

Operating-Cash-Flow-to-Enterprise-Value Ratio: A company’s cash from operations divided by its enterprise value.

Enterprise Value (EV): A company’s market capitalization of equity, plus debt, minority interest and preferred shares, less cash and cash equivalents.

Precious Metals Companies that earn revenue from precious metals through passive means may do so by owning royalties or production streams. Royalties are the right of a company to receive a percentage of the revenues generated from a mine’s production. Production streams are an arrangement where a company provides an upfront payment in exchange for the right to purchase all or a portion of certain metals produced from a mine and may specify a price for such metals in advance of production.

If a Precious Metals Company announces that it is being acquired by another company in exchange for shares of the other company, such Precious Metals Company will be removed from the Index. If a Precious Metals Company announces that it is acquiring another company, such Precious Metals Company will be removed from the Index if the Index Provider determines that the transaction is dilutive (i.e., such transaction is not expected to increase the acquiring firm’s per share revenue, cash flow, or reserves). In such event, the Precious Metals Company removed from the Index will not be eligible to be added to the Index for the two reconstitution dates following the company’s removal from the Index.

If a Precious Metals Company is removed from the Index due to its announcement of acquiring or being acquired by another company, the weight of such position will be re-allocated equally among the remaining Index constituents.

Manager of Managers Structure

The Funds and the Adviser have received exemptive relief from the SEC permitting the Adviser (subject to certain conditions and the approval of the Funds’ Board of Trustees (the “Board”)) to select or change sub-advisers without obtaining shareholder approval. The relief also permits the Adviser to materially amend the terms of agreements with a sub-adviser (including an increase in the fee paid by the Adviser to the sub-adviser (and not paid by the Funds)) or to continue the employment of a sub-adviser after an event that would otherwise cause the automatic termination of services with Board approval, but without shareholder approval. Shareholders will be notified of any sub-adviser changes.

Principal Investment Risks

This section provides additional information regarding the principal risks described in each Fund Summary. As in each Fund Summary, the principal risks below are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk described below is considered a “principal risk” of investing in the applicable Fund, regardless of the order in which it appears. Each of the factors below could have a negative impact on the applicable Fund’s performance and trading prices.

•Airline Companies Risk (U.S. Global Jets ETF (the “Jets ETF”) only). Airline Companies may be adversely affected by a downturn in economic conditions that can result in decreased demand for air travel. Due to the discretionary nature of business and leisure travel spending, airline industry revenues are heavily influenced by the condition of the U.S. economy and economies in other regions of the world. Airline Companies may also be significantly affected by changes in fuel prices, which may be very volatile. Due to the competitive nature of the airline industry, Airline Companies may not be able to pass on increased fuel prices to customers by increasing fares. Airline Companies may also be significantly affected by the imposition of tariffs and/or changes in labor relations, insurance costs, and the imposition by the United States or other countries of taxes or tariffs applicable to airline travel, aircraft manufacturing, or aircraft sales. The trend in the United States has been to deregulate transportation companies, which could have a favorable long-term effect, but future government decisions could adversely affect Airline Companies. Airline Companies may also be highly dependent on aircraft or related equipment from a small number of suppliers, and consequently, issues affecting the availability, reliability, safety, or longevity of such aircraft or equipment (e.g., the inability of a supplier to meet aircraft demand or the grounding of an aircraft due to safety concerns) may have a significant effect on the operations and profitability of Airline Companies.

Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and in many cases unprecedented volatility and severe losses due to the global pandemic caused by COVID‑19, a novel coronavirus. The pandemic has resulted in a wide range of social and economic disruptions, including closed borders and reduced or prohibited domestic or international travel. Some sectors of the economy and individual issuers, including Airline Companies, have experienced particularly large losses. Travel restrictions imposed in the United States and other countries have resulted in Airline Companies seeing dramatically reduced passenger demand and, consequently, reducing flight schedules at unprecedented rates. In particular, certain U.S. passenger airlines have eliminated nearly all international flights for an undetermined length of time. The U.S. airline industry requested and received financial assistance from the U.S. government due to the impact of the pandemic; however, there can be no guarantee as to whether such assistance will be successful in supporting U.S. Airline Companies until the impact of the pandemic subsides.

In addition, the Russian invasion of Ukraine and the resulting Russian sanctions by Western countries, including the United States, Canada, European Union, Japan, United Kingdom, and others, as well as retaliatory measures by Russia, may have a significant impact on Airline Companies. Bans on oil and energy imports from Russia, as well as commitments to phase out such imports in the near future, by certain Western countries may increase the costs of jet fuel. In addition, certain Western nations have closed their airspace to all Russian airlines, as well as Russian-owned and Russian-operated aircraft. Also, Western companies have issued a recall of aircraft leased to Russian airlines and, in certain cases, have seized such aircraft located in Western airports. In response, Russia has closed its airspace to certain Western aircraft, and Russia has seized certain leased aircraft and equipment located in Russia. These actions may lead to higher ticket prices, flight cancellations, longer routes, fewer diversion airports (i.e., airports along a route where a plane can land safely if it is diverted), a decreased demand for travel, and the permanent loss of property for Western companies that leased aircraft to Russian airlines. Increased costs and reduced supply of certain metals exported from Russia, such as titanium, may also slow the production of aircraft and engines, making it more difficult for Airline Companies to increase passenger capacity and repair or upgrade their aircraft. These and any related events could significantly and adversely affect the Fund’s performance and the value of an investment in the Fund.

•Concentration Risk. Each Fund may be susceptible to an increased risk of loss, including losses due to adverse occurrences affecting the Fund more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector or asset class. In addition, at times, a Fund may concentrate in an industry that is out of favor and underperforms other industries or groups of industries or the market as a whole.

•Currency Exchange Rate Risk. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Funds’ investments and the value of your Shares. Because the Funds’ NAV is determined on the basis of U.S. dollars, the U.S. dollar value of your investment in the Funds may go down if the value of the local currency of the non-U.S. markets in which the Funds invest depreciates against the U.S. dollar. This is true even if the local currency value of securities in the Funds’ holdings goes up. Conversely, the dollar value of your investment in the Funds may go up if the value of the local currency appreciates against the U.S. dollar. The value of the U.S. dollar measured against other currencies is influenced by a variety of factors. These factors include: national debt levels and trade deficits, changes in balances of payments and trade, domestic and foreign interest and inflation rates, global or regional political, economic or financial events, monetary policies of governments, actual or potential government intervention, and global energy prices. Political instability, the possibility of government intervention and restrictive or opaque business and investment policies may also reduce the value of a country’s currency. Government monetary policies and the buying or selling of currency by a country’s government may also influence exchange rates. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Funds may change quickly and without warning, and you may lose money.

•Depositary Receipt Risk. The Funds may hold the securities of non-U.S. companies in the form of ADRs and Global Depositary Receipts (“GDRs”). ADRs are negotiable certificates issued by a U.S. financial institution that represent a specified number of shares in a foreign stock and trade on a U.S. national securities exchange, such as the New York Stock Exchange (“NYSE”). Sponsored ADRs are issued with the support of the issuer of the foreign stock underlying the ADRs and carry all of the rights of common shares, including voting rights. GDRs are similar to ADRs, but may be issued in bearer form and are typically offered for sale globally and held by a foreign branch of an international bank. The underlying issuers of certain depositary receipts, particularly unsponsored or unregistered depositary receipts, are under no obligation to distribute shareholder communications to the holders of such receipts, or to pass through to them any voting rights with respect to the deposited securities. Issuers of unsponsored depositary receipts are not contractually obligated to disclose material information in the U.S. and, therefore, such information may not correlate to the market value of the unsponsored depositary receipt. The underlying securities of the ADRs and GDRs in a Fund’s portfolio are usually denominated or quoted in currencies other than the U.S. Dollar. As a result, changes in foreign currency exchange rates may affect the value of a Fund’s portfolio. In addition, because the underlying securities of ADRs and GDRs trade on foreign exchanges at times when the U.S. markets are not open for trading, the value of the securities underlying the ADRs and GDRs may change materially at times when the U.S. markets are not open for trading, regardless of whether there is an active U.S. market for the shares.

•Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to such securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with investments in U.S. securities and instruments. For example, developing and emerging markets may be subject to (i) greater market volatility, (ii) lower trading volume and liquidity, (iii) greater social, political and economic uncertainty, (iv) governmental controls on foreign investments and limitations on repatriation of invested capital, (v) lower disclosure, corporate governance, auditing and financial reporting standards, (vi) fewer protections of property rights, (vii) restrictions on the transfer of securities or currency, and (viii) settlement and trading practices that differ from those in U.S. markets. Each of these factors may impact the ability of the Funds to buy, sell or otherwise transfer securities, adversely affect the trading market and price for Shares and cause the Funds to decline in value.

◦Capital Controls and Sanctions Risk. Economic conditions, such as volatile currency exchange rates and interest rates, political events, military action and other conditions may, without prior warning, lead to government intervention (including intervention by the U.S. government with respect to foreign governments, economic sectors, foreign companies and related securities and interests) and the imposition of capital controls and/or sanctions, which may also include retaliatory actions of one government against another government, such as seizure of assets. Capital controls and/or sanctions include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets. Levies may be placed on profits repatriated by foreign entities (such as the Funds). Capital controls and/or sanctions may also impact the ability of the Funds to buy, sell or otherwise transfer securities or currency, negatively impact the value and/or liquidity of such instruments, adversely affect the trading market and price for Shares, and cause the Funds to decline in value.

◦Geopolitical Risk. Some countries and regions in which the Funds invest have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally. Such geopolitical and other events may also disrupt securities markets and, during such market disruptions, the Funds’ exposure to the other risks described herein will likely increase. Each of the foregoing may negatively impact the Funds’ investments.

•Equity Market Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including: expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; local, regional or global events such as acts of terrorism or war, including Russia’s invasion of Ukraine; and global or regional political, economic, public health, and banking crises. If you held common stock, or common stock equivalents, of any given issuer, you would generally be exposed to greater risk than if you held preferred stocks and debt obligations of the issuer because common stockholders, or holders of equivalent interests, generally have inferior rights to receive payments from issuers in comparison with the rights of preferred stockholders, bondholders, and other creditors of such issuers.

Beginning in the first quarter of 2020, financial markets in the United States and around the world experienced extreme and, in many cases, unprecedented volatility and severe losses due to the global pandemic caused by COVID-19, a novel coronavirus. The pandemic has resulted in a wide range of social and economic disruptions, including closed borders, voluntary or compelled quarantines of large populations, stressed healthcare systems, reduced or prohibited domestic or international travel, and supply chain disruptions affecting the United States and many other countries. Some sectors of the economy and individual issuers have experienced particularly large losses as a result of these disruptions, and such disruptions may continue for an extended period of time or reoccur in the future to a similar or greater extent. In response, the U.S. government and the Federal Reserve have taken extraordinary actions to support the domestic economy and financial markets, resulting in very low interest rates and in some cases negative yields. It is unknown how long circumstances related to the pandemic will persist, whether they will reoccur in the future, whether efforts to support the economy and financial markets will be successful, and what additional implications may follow from the pandemic. The impact of these events and other epidemics or pandemics in the future could adversely affect Fund performance.

•ETF Risks. Each Fund is an ETF, and, as a result of an ETF’s structure, is exposed to the following risks:

◦APs, Market Makers, and Liquidity Providers Concentration Risk. Each Fund has a limited number of financial institutions that may act as APs. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

◦Costs of Buying or Selling Shares. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers, as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the difference between the price at which an investor is willing to buy Shares (the “bid” price) and the price at which an investor is willing to sell Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for Shares based on trading volume and market liquidity, and is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Further, a relatively small investor base in a Fund, asset swings in a Fund and/or increased market volatility may cause increased bid/ask spreads. Due to the costs of buying or selling Shares, including bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate a Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Because securities held by the Funds may trade on foreign exchanges that are closed when such Fund’s primary listing exchange is open, each such Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦Trading. Although Shares are listed for trading on the Exchange and may be listed or traded on U.S. and non-U.S. stock exchanges other than the Exchange, there can be no assurance that an active trading market for such Shares will develop or be maintained. Trading in Shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. In addition, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to Exchange “circuit breaker” rules, which temporarily halt trading on the Exchange when a decline in the S&P 500® Index during a single day reaches certain thresholds (e.g., 7%, 13%, and

20%). Additional rules applicable to the Exchange may halt trading in Shares when extraordinary volatility causes sudden, significant swings in the market price of Shares. There can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of a Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

•Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. issuers. Investments in non-U.S. securities may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there is also the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when a Fund does not price its Shares, the value of the securities in a Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in a Fund more volatile and potentially less liquid than other types of investments.

•Geographic Investment Risk. To the extent that a Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. For example, political and economic conditions and changes in regulatory, tax, or economic policy in a country could significantly affect the market in that country and in surrounding or related countries and have a negative impact on a Fund’s performance. Currency developments or restrictions, political and social instability, and changing economic conditions have resulted in significant market volatility.

◦Australia-Specific Risk (U.S. Global GO GOLD and Precious Metal Miners ETF (the “Miners ETF”) only). Because investments in the metals and mining industry may be geographically concentrated in Australian companies or companies that have a significant presence in Australia, the Fund may be subject to regulatory, political, currency, security, and economic risk specific to Australia. The Australian economy is heavily dependent on exports from the agricultural and mining sectors. As a result, the Australian economy is susceptible to fluctuations in the commodity markets. The Australian economy is also becoming increasingly dependent on its growing services industry. The Australian economy is dependent on trading with key trading partners, including the United States, China, Japan, Singapore, and certain European countries. Reduction in spending on Australian products and services, or changes in any of the economies, may cause an adverse impact on the Australian economy. The agricultural and mining sectors of Australia’s economy account for the majority of its exports. Australia is susceptible to fluctuations in the commodity markets and, in particular, in the price and demand for agricultural products and natural resources. Any negative changes in these sectors could have an adverse impact on the Australian economy. Additionally, Australia is located in a part of the world that has historically been prone to natural disasters, such as hurricanes and droughts, and is economically sensitive to environmental events. Any such event may adversely impact the Australian economy, causing an adverse impact on the value of the Fund’s Australian securities.

◦Canada-Specific Risk (Miners ETF only). Because investments in the metals and mining industry may be geographically concentrated in Canadian companies or companies that have a significant presence in Canada, investment results could be dependent on the financial condition of the Canadian economy. The Canadian economy is reliant on the sale of natural resources and commodities, which can pose risks such as the fluctuation of prices and the variability of demand for exportation of such products. Changes in spending on Canadian products by the economies of other countries or changes in any of these economies may cause a significant impact on the Canadian economy.

◦South Africa-Specific Risk (Miners ETF only). Because investments in the metals and mining industry may be geographically concentrated in South African companies or companies that have a significant presence in South Africa, investment results could be dependent on the financial condition of the South African economy. South Africa’s economy exhibits characteristics of both a developed country and a developing country and has historically experienced extremely uneven distribution of wealth and income and high rates of unemployment. The securities markets in South Africa are subject to greater risks associated with market volatility, lower market capitalization, lower trading volume, illiquidity, inflation, greater price fluctuations, uncertainty regarding the existence of trading markets, governmental control, and heavy regulation of labor and industry. In addition, South Africa’s currency has at times been at risk of devaluation due to inadequate foreign currency reserve. While economic reforms have been enacted in recent periods, there can be no assurance that these reforms will achieve the intended results. Furthermore, adverse social and economic conditions in a neighboring country may have a significant adverse effect on South Africa. Additionally, the agriculture and mining sectors of South Africa’s economy account for a large portion of its exports, and thus the South African economy is

susceptible to fluctuations in these commodity markets. South Africa is located in a part of the world that has historically been prone to natural disasters, such as droughts, and is economically sensitive to environmental events. Any such event may adversely impact South Africa’s economy or business operations of companies in South Africa, causing an adverse impact on the value of the Fund.

•Gold and Precious Metals Risk (Miners ETF only). The Fund will be sensitive to changes in, and its performance will depend to a greater extent on, the overall condition of the metals and mining industry. Competitive pressures may have a significant effect on the financial condition of companies in such industry. Also, such companies are highly dependent on the price of certain precious metals. These prices may fluctuate substantially over short periods of time, so the Fund’s Share price may be more volatile than other types of investments. The prices of precious metals rise and fall in response to many factors, including: economic cycles; changes in inflation or expectations about inflation in various countries; interest rates; currency fluctuations; metal sales by governments, central banks, or international agencies; investment speculation; resource availability; fluctuations in industrial and commercial supply and demand; government regulation of the metals and materials industries; and government prohibitions or restrictions on the private ownership of certain precious and rare metals. The Index measures the performance of equity securities of Precious Metals Companies and does not measure the performance of direct investment in precious metals. Consequently, the Fund’s Share price may not move in the same direction and to the same extent as the spot prices of precious metals.

In times of stable economic growth, traditional equity and debt investments could offer greater appreciation potential, and the value of precious metals may be adversely affected, which could in turn affect the Fund’s returns. The production and sale of precious metals by governments, central banks, or other large holders can be affected by various economic, financial, social, and political factors, which may be unpredictable and may have a significant impact on the supply and prices of precious metals. Economic and political conditions in those countries that are the largest producers of precious metals may have a direct effect on the production and marketing of such metals and on sales of central bank holdings. Some precious metals mining operation companies may hedge their exposure to falls in precious metals prices by selling forward future production, which may result in lower returns during periods when the price of precious metals increases. The precious metals industry can be significantly affected by events relating to international political developments, the success of exploration projects, commodity prices, and tax and government regulations. If a natural disaster or other event with a significant economic impact occurs in a region where the companies in which the Fund invests operate, such disaster or event could negatively affect the profitability of such companies and, in turn, the Fund’s investment in them.

•Market Capitalization Risk

◦Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies, but they may also be subject to slower growth than small-capitalization companies during times of economic expansion. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole, but they may also be nimbler and more responsive to new challenges than large-capitalization companies. Some mid-capitalization companies have limited product lines, markets, financial resources, and management personnel and tend to concentrate on fewer geographical markets relative to large-capitalization companies.

◦Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

•Non-Diversification Risk. Each Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, a Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase a Fund’s volatility and cause the performance of a relatively smaller

number of issuers to have a greater impact on such Fund’s performance. However, each Fund intends to satisfy the diversification requirements for qualifying as a RIC under Subchapter M of the Code.

•Passive Investment Risk. Each Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. Each Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, a Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. The returns from the types of securities in which a Fund invests may underperform returns from the various general securities markets or different asset classes. This may cause a Fund to underperform other investment vehicles that invest in different asset classes. Different types of securities (for example, large-, mid- and small-capitalization stocks) tend to go through cycles of doing better – or worse – than the general securities markets. In the past, these periods have lasted for as long as several years.

•Portfolio Turnover Risk (U.S. Global GO GOLD and Precious Metal Miners ETF (the “Miners ETF”) only). The Fund may trade all or a significant portion of the securities in its portfolio in connection with each rebalance and reconstitution of its Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains.

•Securities Lending Risk. Each Fund may engage in securities lending. A Fund may lose money if the borrower of the loaned securities delays returning in a timely manner or fails to return the loaned securities. Securities lending involves the risk that a Fund could lose money in the event of a decline in the value of collateral provided for loaned securities. In addition, a Fund bears the risk of loss in connection with its investment of the cash collateral it receives from a borrower. To the extent that the value or return of a Fund’s investment of the cash collateral declines below the amount owed to the borrower, a Fund may incur losses that exceed the amount it earned on lending the security.

•Tax Risk. To qualify for the favorable tax treatment generally available to RICs, the Funds must satisfy, among other requirements described in the SAI, certain diversification requirements. In particular, at the close of each quarter of a Fund’s taxable year: (A) at least 50% of the value of its total assets must be represented by cash and cash items, U.S. government securities, securities of other RICs and other securities, with such other securities limited, in respect to any one issuer, to an amount not greater than 5% of the value of the Fund’s total assets and that does not represent more than 10% of the outstanding voting securities of such issuer, including the equity securities of a qualified publicly traded partnership, and (B) not more than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in the securities (other than U.S. government securities or securities of other RICs) of any one issuer or the securities (other than the securities of another RIC) of two or more issuers that the Fund controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or the securities of one or more qualified publicly traded partnerships. While the weighting of the Index is not inconsistent with these rules, given the concentration of the Index in a relatively small number of securities, it may not always be possible for the Funds to fully implement a replication strategy or a representative sampling strategy while satisfying these diversification requirements. The Funds’ efforts to satisfy the diversification requirements may affect a Fund’s execution of their investment strategy and may cause the Fund’s return to deviate from that of the Index, and the Fund’s efforts to replicate or represent the Index may cause it inadvertently to fail to satisfy the diversification requirements. If a Fund were to fail to satisfy the diversification requirements, it could be eligible for relief provisions if the failure is due to reasonable cause and not willful neglect and if a penalty tax is paid with respect to each failure to satisfy the applicable requirements. Additionally, relief is provided for certain de minimis failures of the diversification requirements where the Fund corrects the failure within a specified period. If a Fund were to fail to qualify as a RIC for a tax year, and the relief provisions are not available, it would be taxed in the same manner as an ordinary corporation, and distributions to its shareholders would not be deductible by the Fund in computing its taxable income. In such case, a Fund’s shareholders would be taxed as if they received ordinary dividends, although corporate shareholders could be eligible for the dividends received deduction (subject to certain limitations) and individuals may be able to benefit from the lower tax rates available to qualified dividend income. In addition, a Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make substantial distributions before requalifying as a RIC.

•Tracking Error Risk. As with all index funds, the performance of each Fund and its respective Index may differ from each other for a variety of reasons. For example, the Funds incur operating expenses and portfolio transaction costs not incurred by an Index. In addition, the Funds may not be fully invested in the securities of their respective Index at all times or may hold securities not included in the Index. A Fund may use a representative sampling strategy to achieve its investment objective, if the Fund’s Adviser believes it is in the best interest of the Fund, which generally can be expected to produce a greater non-correlation risk.

PORTFOLIO HOLDINGS INFORMATION

Information about the Funds’ daily portfolio holdings is available at www.usglobaletfs.com. A description of the Funds’ policies and procedures with respect to the disclosure of the Funds’ portfolio holdings is available in the Funds’ Statement of Additional Information (“SAI”).

MANAGEMENT

Investment Adviser

U.S. Global Investors, Inc. serves as the investment adviser and has overall responsibility for the general management and administration of the Funds. The Adviser also arranges for transfer agency, custody, fund administration, distribution and all other related services necessary for the Funds to operate. For the services it provides to the Funds, the Funds pay the Adviser a unified management fee, which is calculated daily and paid monthly, at an annual rate of 0.60% of each Fund’s average daily net assets. Under the investment advisory agreement, the Adviser has agreed to pay all expenses incurred by the Funds except for interest charges on any borrowings, taxes, brokerage commissions and other expenses incurred in placing orders for the purchase and sale of securities and other investment instruments, acquired fund fees and expenses, accrued deferred tax liability, extraordinary expenses, distribution fees and expenses paid by the Funds under any distribution plan adopted pursuant to Rule 12b‑1 under the Investment Company Act of 1940, as amended (the “1940 Act”), and the unified management fee payable to the Adviser.

The Adviser has managed various investment portfolios for clients since 1968, including other investment companies. The Adviser is a Texas corporation and is located at 7900 Callaghan Road, San Antonio, Texas 78229.

The basis for the Board’s approval of each Fund’s Investment Advisory Agreement is available in the Fund’s Annual Report to Shareholders for the year ended December 31, 2021.

Portfolio Managers

The Funds are managed by a team consisting of the following individuals, each of whom is equally responsible for the day to day management of each Fund’s portfolio. Frank E. Holmes, Chief Executive Officer and Director for the Adviser since 1989 and has been a portfolio manager of the Jets ETF since its inception in 2015 and of the Miners ETF since its inception in 2017. Ralph P. Aldis, CFA, has been a Portfolio Manager for the Adviser since 2001 and a portfolio manager of the Jets ETF since its inception in 2015 and of the Miners ETF since its inception in 2017.

The Funds’ SAI provides additional information about the Portfolio Managers’ compensation structure, other accounts managed by the Portfolio Managers, and the Portfolio Managers’ ownership of Shares of each Fund.

HOW TO BUY AND SELL SHARES

Each Fund issues and redeems Shares at NAV only in Creation Units. Only APs may acquire Shares directly from a Fund, and only APs may tender their Shares for redemption directly to a Fund, at NAV. APs must be a member or participant of a clearing agency registered with the SEC and must execute a Participant Agreement that has been agreed to by the Distributor (defined below), and that has been accepted by a Fund’s transfer agent, with respect to purchases and redemptions of Creation Units. Once created, Shares trade in the secondary market in quantities less than a Creation Unit.

Most investors buy and sell Shares in secondary market transactions through brokers. Shares are listed for trading on the secondary market on the Exchange and can be bought and sold throughout the trading day like other publicly traded securities.

When buying or selling Shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offer price in the secondary market on each leg of a round trip (purchase and sale) transaction. In addition, because secondary market transactions occur at market prices, you may pay more than NAV when you buy Shares and receive less than NAV when you sell those Shares.

Book Entry

Shares are held in book-entry form, which means that no stock certificates are issued. The Depository Trust Company (“DTC”) or its nominee is the record owner of all outstanding Shares.

Investors owning Shares are beneficial owners as shown on the records of DTC or its participants. DTC serves as the securities depository for all Shares. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and other institutions that directly or indirectly maintain a custodial relationship with DTC. As a beneficial owner of Shares, you are not entitled to receive physical delivery of stock certificates or to have Shares registered in your name, and you are not considered a registered owner of Shares. Therefore, to exercise any right as an owner of Shares, you must rely upon the procedures of DTC and its participants. These procedures are the same as those that apply to any other securities that you hold in book entry or “street name” through your brokerage account.

Frequent Purchases and Redemptions of Shares

The Funds impose no restrictions on the frequency of purchases and redemptions of Shares. In determining not to approve a written, established policy, the Board evaluated the risks of market timing activities by Fund shareholders. Purchases and redemptions by APs, who are the only parties that may purchase or redeem Shares directly with a Fund, are an essential part of the ETF process and help keep Share trading prices in line with NAV. As such, the Funds accommodate frequent purchases and redemptions by APs. However, the Board has also determined that frequent purchases and redemptions for cash may increase tracking error and portfolio transaction costs and may lead to the realization of capital gains. To minimize these potential consequences of frequent purchases and redemptions, the Funds employ fair value pricing and may impose transaction fees on purchases and redemptions of Creation Units to cover the custodial and other costs incurred by a Fund in effecting trades. In addition, the Funds and the Adviser reserve the right to reject any purchase order at any time.

Determination of Net Asset Value

Each Fund’s NAV is calculated as of the scheduled close of regular trading on the NYSE, generally 4:00 p.m. Eastern time, each day the NYSE is open for business. Each NAV for a Fund is calculated by dividing the applicable Fund’s net assets by its Shares outstanding.

In calculating its NAV, each Fund generally values its assets on the basis of market quotations, last sale prices, or estimates of value furnished by a pricing service or brokers who make markets in such instruments. If such information is not available for a security held by a Fund or is determined to be unreliable, the security will be valued at fair value estimates under guidelines established by the Board (as described below).

In calculating its NAV, the Funds generally value equity securities (including preferred stock) traded on any recognized U.S. or non-U.S. exchange at the last sale price or official closing price on the exchange or system on which they are principally traded. In addition, the Funds may invest in money market funds that are valued at their NAV per share.

Fair Value Pricing

The Board has adopted procedures and methodologies to fair value Fund securities whose market prices are not “readily available” or are deemed to be unreliable. For example, such circumstances may arise when: (i) a security has been de-listed or has had its trading halted or suspended; (ii) a security’s primary pricing source is unable or unwilling to provide a price; (iii) a security’s primary trading market is closed during regular market hours; or (iv) a security’s value is materially affected by events occurring after the close of the security’s primary trading market. Generally, when fair valuing a security, the Funds will take into account all reasonably available information that may be relevant to a particular valuation including, but not limited to, fundamental analytical data regarding the issuer, information relating to the issuer’s business, recent trades or offers of the security, general and/or specific market conditions and the specific facts giving rise to the need to fair value the security. Fair value determinations are made in good faith and in accordance with the fair value methodologies included in the Board-adopted valuation procedures. Due to the subjective and variable nature of fair value pricing, there can be no assurance that the Adviser will be able to obtain the fair value assigned to the security upon the sale of such security.

Investments by Registered Investment Companies

Section 12(d)(1) of the 1940 Act restricts investments by registered investment companies in the securities of other investment companies, including Shares. Registered investment companies are permitted to invest in a Fund beyond the limits set forth in section 12(d)(1) subject to certain terms and conditions set forth in a rule under the 1940 Act, including that such investment companies enter into an agreement with a Fund.

Delivery of Shareholder Documents – Householding

Householding is an option available to certain investors of the Funds. Householding is a method of delivery, based on the preference of the individual investor, in which a single copy of certain shareholder documents can be delivered to investors who share the same address, even if their accounts are registered under different names. Householding for the Funds is available through certain broker-dealers. If you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, please contact your broker-dealer. If you are currently enrolled in householding and wish to change your householding status, please contact your broker-dealer.

DIVIDENDS, DISTRIBUTIONS AND TAXES

Dividends and Distributions

Each Fund intends to pay out dividends, if any, and distribute any net realized capital gains to its shareholders at least annually. Each Fund will declare and pay capital gain distributions, if any, in cash. Distributions in cash may be reinvested automatically in additional

whole Shares only if the broker through whom you purchased Shares makes such option available. Your broker is responsible for distributing the income and capital gain distributions to you.

Taxes

The following discussion is a summary of some important U.S. federal income tax considerations generally applicable to investments in the Funds. Your investment in a Fund may have other tax implications. Please consult your tax advisor about the tax consequences of an investment in Shares, including the possible application of foreign, state, and local tax laws.

Each Fund has elected and intends to qualify each year for treatment as a RIC. If a Fund meets certain minimum distribution requirements, a RIC is not subject to tax at the fund level on income and gains from investments that are timely distributed to shareholders. However, a Fund’s failure to qualify as a RIC or to meet minimum distribution requirements would result (if certain relief provisions were not available) in fund-level taxation and, consequently, a reduction in income available for distribution to shareholders.

Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged account, such as an IRA plan, you need to be aware of the possible tax consequences when a Fund makes distributions, when you sell your Shares listed on the Exchange; and when you purchase or redeem Creation Units (APs only).

Taxes on Distributions

Each Fund intends to distribute, at least annually, substantially all of its net investment income and net capital gains. For federal income tax purposes, distributions of investment income are generally taxable as ordinary income or qualified dividend income. Taxes on distributions of capital gains (if any) are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her Shares. Sales of assets held by a Fund for more than one year generally result in long-term capital gains and losses, and sales of assets held by a Fund for one year or less generally result in short-term capital gains and losses. Distributions of a Fund’s net capital gain (the excess of net long-term capital gains over net short-term capital losses) that are reported by such Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable as long-term capital gains, which for non-corporate shareholders are subject to tax at reduced rates of up to 20% (lower rates apply to individuals in lower tax brackets). Distributions of short-term capital gain will generally be taxable as ordinary income. Dividends and distributions are generally taxable to you whether you receive them in cash or reinvest them in additional Shares.

Distributions reported by the Funds as “qualified dividend income” are generally taxed to non-corporate shareholders at rates applicable to long-term capital gains, provided holding period and other requirements are met. “Qualified dividend income” generally is income derived from dividends paid by U.S. corporations or certain foreign corporations that are either incorporated in a U.S. possession or eligible for tax benefits under certain U.S. income tax treaties. In addition, dividends that a Fund received in respect of stock of certain foreign corporations may be qualified dividend income if that stock is readily tradable on an established U.S. securities market. Corporate shareholders may be entitled to a dividends received deduction for the portion of dividends they receive from the Funds that are attributable to dividends received by the Funds from U.S. corporations, subject to certain limitations. A Fund’s investment strategy may limit the amount of distributions eligible for treatment as qualified dividend income in the hands of non-corporate shareholders or eligible for the dividends received deduction for corporate shareholders.

Shortly after the close of each calendar year, you will be informed of the amount and character of any distributions received from a Fund.

In general, your distributions are subject to federal income tax for the year in which they are paid. Certain distributions paid in January, however, may be treated as paid on December 31 of the prior year. Distributions are generally taxable even if they are paid from income or gains earned by a Fund before your investment (and thus were included in the Shares’ NAV when you purchased your Shares).

You may wish to avoid investing in a Fund shortly before a dividend or other distribution, because such a distribution will generally be taxable even though it may economically represent a return of a portion of your investment.

If a Fund’s distributions exceed its earnings and profits, all or a portion of the distributions made for a taxable year may be recharacterized as a return of capital to shareholders. A return of capital distribution will generally not be taxable, but will reduce each shareholder’s cost basis in Shares and result in a higher capital gain or lower capital loss when the Shares are sold. After a shareholder’s basis in Shares has been reduced to zero, distributions in excess of earnings and profits in respect of those Shares will be treated as gain from the sale of the Shares.

If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than Capital Gain Dividends) paid to you by a Fund will generally be subject to a U.S. withholding tax at the rate of 30%, unless a lower treaty rate applies. Gains from the sale or other disposition of your Shares generally are not subject to U.S. taxation, unless you are a nonresident alien individual who is physically present in the U.S. for 183 days or more per year. A Fund may, under certain circumstances, report

all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met. Different tax consequences may result if you are a foreign shareholder engaged in a trade or business within the United States or if a tax treaty applies.

Under legislation generally known as “FATCA” (the Foreign Account Tax Compliance Act), a Fund is required to withhold 30% of certain ordinary dividends it pays to shareholders that are foreign entities and that fail to meet prescribed information reporting or certification requirements.

Each Fund (or a financial intermediary, such as a broker, through which a shareholder owns Shares) generally is required to withhold and remit to the U.S. Treasury a percentage of the taxable distributions and sale or redemption proceeds paid to any shareholder who fails to properly furnish a correct taxpayer identification number, who has underreported dividend or interest income, or who fails to certify that the shareholder is not subject to such withholding.

Taxes When Shares are Sold on the Exchange

Any capital gain or loss realized upon a sale of Shares generally is treated as a long-term capital gain or loss if Shares have been held for more than one year and as a short-term capital gain or loss if Shares have been held for one year or less. However, any capital loss on a sale of Shares held for six months or less is treated as long-term capital loss to the extent of Capital Gain Dividends paid with respect to such Shares. Any loss realized on a sale will be disallowed to the extent Shares of a Fund are acquired, including through reinvestment of dividends, within a 61-day period beginning 30 days before and ending 30 days after the disposition of Shares. The ability to deduct capital losses may be limited.

The cost basis of Shares of a Fund acquired by purchase will generally be based on the amount paid for the Shares and then may be subsequently adjusted for other applicable transactions as required by the Code. The difference between the selling price and the cost basis of Shares generally determines the amount of the capital gain or loss realized on the sale or exchange of Shares. Contact the broker through whom you purchased your Shares to obtain information with respect to the available cost basis reporting methods and elections for your account.

Taxes on Purchases and Redemptions of Creation Units

An AP having the U.S. dollar as its functional currency for U.S. federal income tax purposes who exchanges securities for Creation Units generally recognizes a gain or a loss. The gain or loss will be equal to the difference between the value of the Creation Units at the time of the exchange and the exchanging AP’s aggregate basis in the securities delivered, plus the amount of any cash paid for the Creation Units. An AP who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanging AP’s basis in the Creation Units and the aggregate U.S. dollar market value of the securities received, plus any cash received for such Creation Units. The Internal Revenue Service may assert, however, that a loss that is realized upon an exchange of securities for Creation Units may not be currently deducted under the rules governing “wash sales” (for an AP who does not mark-to-market their holdings), or on the basis that there has been no significant change in economic position. APs exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Any gain or loss realized upon a creation or redemption of Creation Units will be treated as capital or ordinary gain or loss, depending on the circumstances. Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if Shares have been held for more than one year and as a short-term capital gain or loss if Shares have been held for one year or less.

A Fund may include a payment of cash in addition to, or in place of, the delivery of a basket of securities upon the redemption of Creation Units. Such Fund may sell portfolio securities to obtain the cash needed to distribute redemption proceeds. This may cause such Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, such Fund may be less tax efficient if it includes such a cash payment in the proceeds paid upon the redemption of Creation Units.

Net Investment Income Tax

U.S. individuals with income exceeding specified thresholds are subject to a 3.8% tax on all or a portion of their “net investment income,” which includes interest, dividends, and certain capital gains (generally including capital gains distributions and capital gains realized on the sale of Shares). This 3.8% tax also applies to all or a portion of the undistributed net investment income of certain shareholders that are estates and trusts.

Foreign Investments by the Funds

Interest and other income received by a Fund with respect to foreign securities may give rise to withholding and other taxes imposed by foreign countries. Tax conventions between certain countries and the United States may reduce or eliminate such taxes. If as of the close of a taxable year more than 50% of the value of a Fund’s assets consists of certain foreign stock or securities, each such Fund will be eligible to elect to “pass through” to investors the amount of foreign income and similar taxes (including withholding taxes)

paid by such Fund during that taxable year. This means that investors would be considered to have received as additional income their respective Shares of such foreign taxes, but may be entitled to either a corresponding tax deduction in calculating taxable income, or, subject to certain limitations, a credit in calculating federal income tax. If a Fund does not so elect, each such Fund will be entitled to claim a deduction for certain foreign taxes incurred by such Fund. A Fund (or its administrative agent) will notify you if it makes such an election and provide you with the information necessary to reflect foreign taxes paid on your income tax return.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in each Fund. It is not a substitute for personal tax advice. You also may be subject to state and local tax on Fund distributions and sales of Shares. Consult your personal tax advisor about the potential tax consequences of an investment in Shares under all applicable tax laws. For more information, please see the section entitled “Federal Income Taxes” in the SAI.

DISTRIBUTION

The Distributor, Quasar Distributors, LLC, is a broker-dealer registered with the SEC. The Distributor distributes Creation Units for the Funds on an agency basis and does not maintain a secondary market in Shares. The Distributor has no role in determining the policies of the Funds or the securities that are purchased or sold by the Funds. The Distributor’s principal address is 111 East Kilbourn Avenue, Suite 2200, Milwaukee, Wisconsin 53202.

The Board has adopted a Distribution and Service Plan (the “Plan”) pursuant to Rule 12b-1 under the 1940 Act. In accordance with the Plan, each Fund is authorized to pay an amount up to 0.25% of its average daily net assets each year for certain distribution-related activities and shareholder services.

No Rule 12b-1 fees are currently paid by the Funds, and there are no plans to impose these fees. However, in the event Rule 12b-1 fees are charged in the future, because the fees are paid out of Fund assets, over time these fees will increase the cost of your investment and may cost you more than certain other types of sales charges.

PREMIUM/DISCOUNT INFORMATION

Information regarding how often Shares traded on the Exchange at a price above (i.e., at a premium) or below (i.e., at a discount) the NAV per Share is available, free of charge, on the Funds’ website at www.usglobaletfs.com.
