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. Airline Companies may also be significantly affected by the imposition of tariffs and/or changes in labor relations and insurance costs.

Concentration Risk . The 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.

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 and certain additional risks. 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.

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, sectors or companies 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.

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. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

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 . Although the Fund intends to invest in a variety of securities and instruments, the Fund will be 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.

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.

Shares May Trade at Prices Other Than NAV. As with all exchange-traded funds (“ETFs”), Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of the Shares will approximate the Fund’s NAV, there may be times when the market price of the Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of the 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 the Shares in the secondary market. Because securities held by the Fund 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.

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.

Tax Risk. To qualify for the favorable tax treatment generally available to a regulated investment company (“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.

Tracking Error Risk. As with all index funds, the performance of the Fund and its 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.

Concentration Risk . The 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.

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 and certain additional risks. 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.

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, sectors or companies 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.

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. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

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.

Africa-Specific Risk .  Because investments in the metals and mining industry may be geographically concentrated in companies that have a significant presence in Africa, investment results could be dependent on the financial, political, and social climate of the African countries in which these companies operate. The African economy is diverse, and certain African markets are in the early stages of development, with less liquidity and more capital market restrictions compared to developed markets. In addition, many countries in Africa have long histories of political, social, and economic instability and, as a result, have suffered from expropriation and/or nationalization of assets, confiscatory taxation, authoritarian and/or military involvement in governmental decision-making, armed conflict, negative impacts on the economy as a result of civil war, and religious, ethnic and/or socioeconomic unrest and, in certain countries, genocidal warfare. Because African markets are heavily dependent on the exportation of natural resources, they may be negatively impacted by changes in commodity prices. Changes in spending on African products by the economies of other countries or changes in any of these economies may cause a significant impact on the African economy.

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.

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 previous 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.

Limited Operating History. The Fund is a recently organized, non-diversified management investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

Non-Diversification Risk . Although the Fund intends to invest in a variety of securities and instruments, the Fund will be 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.

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.

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 the Shares will approximate the Fund’s NAV, there may be times when the market price and the NAV vary significantly, including due to supply and demand of Shares and/or during periods of market volatility. Thus, you may pay more (or less) than NAV intra-day when you buy Shares in the secondary market, and you may receive more (or less) than NAV when you sell Shares in the secondary market. 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 trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.

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.

Tax Risk. To qualify for the favorable tax treatment generally available to a regulated investment company (“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.

Tracking Error Risk. As with all index funds, the performance of the Fund and its 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.

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.

Concentration Risk . The Funds may be susceptible to an increased risk of loss, including losses due to adverse occurrences affecting the Funds more than the market as a whole, to the extent that the Funds’ 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.

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; and global or regional political, economic 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.

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 the Funds do not price their 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 Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Each of these factors can make investments in the Funds more volatile and potentially less liquid than other types of investments.

Geographic Investment Risk. To the extent that a Fund’s Index 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.

o

Australia-Specific Risk (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.

●

Limited Operating History (Miners ETF only). The Fund is a recently organized, non-diversified management investment company with a limited operating history. As a result, prospective investors have a limited track record or history on which to base their investment decision.

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. 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. Some medium 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. Although the Funds intend to invest in a variety of securities and instruments, the Funds will be considered to be non-diversified. This means that the Funds may invest more of their assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, the Funds 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 a Fund’s performance.

Passive Investment Risk. The Funds invest in the securities included in, or representative of, its Index regardless of their investment merit. The Funds do not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Funds’ 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 the Funds invest may underperform returns from the various general securities markets or different asset classes. This may cause the Funds 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.

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 the Shares will approximate the Funds’ 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. In times of severe market disruption, shares are most likely to be traded at a discount to NAV, and the discount is likely to be greatest when the price of Shares is falling fastest, which may be the time that you most want to sell your Shares. The Adviser believes that, under normal market conditions, large market price discounts or premiums to NAV will not be sustained because of arbitrage opportunities. Because securities held by the Funds trade on foreign exchanges that are closed when the Funds’ primary listing exchange is open, there are likely to be deviations between the current price of an underlying security and the security’s last quoted price from the closed foreign market. This may result in premiums and discounts that are greater than those experienced by domestic ETFs.

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, a Fund may not be fully invested in the securities of its Index at all times or may hold securities not included in its Index. The use of sampling techniques may affect a Fund’s ability to achieve close correlation with its Index. The Funds may use a representative sampling strategy to achieve their investment objective, which generally can be expected to produce a greater non-correlation risk.

Trading.  Although the 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 the 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 percent, 13 percent, and 20 percent). Additional rules applicable to the Exchange may halt trading in the Shares when extraordinary volatility causes sudden, significant swings in the market price of the Shares. There can be no assurance that the 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.

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 the Shares have more trading volume and market liquidity and higher if the Shares have little trading volume and market liquidity. In times of severe market disruption, the bid/ask spread can increase significantly. 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.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk.  The Funds have 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.
