General Market Risk.    The Fund is subject to all of the business risks and uncertainties associated with any mutual fund, including the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.

Concentration Risk.    The Fund’s investment strategy means that the performance of the Fund will be closely tied to the performance of the energy infrastructure industry. The Fund’s focus in this industry presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if one or two of its investments perform poorly.

Equity Securities Risk.    Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund 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 industries, sectors, geographic markets, the equity securities of energy infrastructure companies in particular, or a particular company in which the Fund invests.

Currency Risk.    When the Fund buys or sells securities on a foreign stock exchange, the transaction is undertaken in the local currency rather than in U.S. dollars, which carries the risk that the value of the foreign currency will increase or decrease, which may impact the value of the Fund’s portfolio holdings and your investment. Foreign countries may adopt economic policies

and/or currency exchange controls that affect its currency valuations in a disadvantageous manner for U.S. investors and companies and restrict or prohibit the Fund’s ability to repatriate both investment capital and income, which could place the Fund’s assets in such country at risk of total loss.

MLP Affiliate Risk.    The performance of securities issued by MLP affiliates, including common shares of corporations that own general partner interests, primarily depends on the performance of an MLP. The risks and uncertainties that affect the MLP, its operational results, financial condition, cash flows and distributions also affect the value of securities held by that MLP’s affiliate.

Debt Securities Risk.    Investments in fixed income securities will be subject to credit risk, interest rate risk and prepayment risk. Credit risk is the risk that an issuer will default or fail to pay principal and interest when due. Interest rate risk is the risk that the value of fixed income securities fluctuates with changes in interest rates (e.g., increases in interest rates result in a decrease in value of fixed income securities). The Fund will be exposed to heightened interest rate risk as interest rates rise from historically low levels. Pre-payment risk is the risk that the principal on fixed income securities will be paid off prior to maturity causing the Fund to invest in fixed income securities with lower interest rates. Duration risk is the risk that holding long duration and long maturity investments will magnify certain other risks, including interest rate risk and credit risk.

Large Cap Company Risk.    The Fund’s investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in consumer tastes or innovative smaller competitors potentially resulting in lower markets for their common stock.

Investment Company and RIC Compliance Risk.    The Fund may be subject to increased expenses and reduced performance as a result of its investments in other investment companies and MLPs. When investing in other investment companies, the Fund bears its pro rata share of the other investment company’s fees and expenses including the duplication of advisory and other fees and expenses. The Fund’s investment in MLPs presents unusual challenges in qualifying each year as a “regulated investment company” (a “RIC”) under the Code, a designation which allows the Fund to avoid paying taxes at regular corporate rates on its income. If for any taxable year the Fund fails to qualify as a RIC, the Fund’s taxable income will be subject to federal income tax at regular corporate rates. The resulting increase to the Fund’s expenses will reduce its performance and its income available for distribution to shareholders.

Cybersecurity Risk.    Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses. Such cyber networks might in some circumstances be at risk of cyber-attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.

Energy Infrastructure Industry Risk.    Companies in the energy infrastructure industry are subject to many risks that can negatively impact the revenues and viability of companies in this industry, including, but not limited to risks associated with companies owning and/or operating pipelines, gathering and processing assets, power infrastructure, propane assets, as well as capital markets, terrorism, natural disasters, climate change, operating, regulatory, environmental, supply and demand, and price volatility risks.

Convertible Securities Risk.    Convertible securities are hybrid securities that have characteristics of both bonds and common stocks and are therefore subject to both debt security risks and equity risk. Convertible securities are subject to equity risk especially when their conversion value is greater than the interest and principal value of the bond. The prices of equity securities may rise or fall because of economic or political changes and may decline over short or extended periods of time.

Tax Risk.    The Fund has elected to be, and intends to qualify each year for treatment as, a “regulated investment company” under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). To maintain qualification for federal income tax purposes as a regulated investment company under the Code, the Fund must meet certain source-of-income, asset diversification and annual distribution requirements, as discussed in detail below under “Tax Consequences.”

Depreciation or other cost recovery deductions passed through to the Fund from investments in MLPs in a given year will generally reduce the Fund’s taxable income, but those deductions may be recaptured in the Fund’s income in one or more subsequent years. When recognized and distributed, recapture income will generally be taxable to shareholders at the time of the distribution at ordinary income tax rates, even though those shareholders might not have held shares in the Fund at the time the deductions were taken by the Fund, and even though those shareholders will not have corresponding economic gain on their shares at the time of the recapture. In order to distribute recapture income or to fund redemption requests, the Fund may need to liquidate investments, which may lead to additional recapture income.

General Market Risk.    The Fund is subject to the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.

Depository Receipt Risk.    Investing in Depository Receipts may be subject to certain risks associated with direct investments in the securities of foreign companies, such as currency, political, economic and market risks. Depository Receipts may be less liquid than the underlying shares in the primary trading market. Depository Receipts may not track the price of their underlying foreign securities on which they are based, may have limited voting rights, and may have a distribution subject to a fee charged by the depository. As a result, equity shares of the underlying issuer may trade at a discount or premium to the market price of the depository receipts.

Equity Securities Risk.    Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value. The equity securities held by the Fund may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors affecting securities markets generally, the equity securities of water companies in particular, or a particular company.

Mid-Cap and Small-Cap Companies Risk.    Companies defined as small and mid-cap securities may involve greater risk than is normally associated with large cap companies, and as a result may be more volatile and less liquid than the securities of large-cap companies, and may have returns that vary substantially from the overall securities markets.

Liquidity Risk.    The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities at an advantageous price or in a timely manner. Illiquid or restricted securities cannot be sold immediately because of statutory and contractual restrictions on resale.

Tracking Error Risk.    There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. The Fund’s return may not match the return of its Underlying Index for a number of reasons, including differences between the securities held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the Fund’s holding of cash, differences in timing of the accrual of distributions, changes to the Underlying Index or the need to meet various new or existing regulatory requirements. Consequently, the performance of the Fund may diverge from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions, or due to delays of the Fund in purchasing and selling securities. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Absence of Active Trading Market Risk.    Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Trading Risks.    The Fund faces numerous trading risks, including disruption in the creation/redemption process of the Fund and losses from trading in the secondary markets. Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons or due to extraordinary market volatility pursuant to “circuit breaker” rules on the Exchange or market. Additionally, an exchange or market may also close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Methodology Risks.    The Index Provider relies on various sources of information to assess the criteria of issuers included in the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Index Provider can offer assurances that the Underlying Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers or that the included issuers will provide the Fund with the market exposure it seeks.

General Market Risk.    The Fund is subject to the risk that it will not achieve its investment objective and that the value of an investment in its securities could decline substantially and cause you to lose some or all of your investment. The Fund’s net asset value (“NAV”) and investment return will fluctuate based upon changes in the value of its portfolio securities. Certain securities in the Fund’s portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time.

Concentration Risk.    Because the Fund’s assets will be concentrated in the energy pipeline industry, the Fund is subject to loss due to adverse occurrences that may affect that industry. The Fund’s focus in this industry presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if a small number of its investments perform poorly.

Pipeline Company Risk.    Pipeline Companies are subject to many risks, including varying demand for crude oil, natural gas, natural gas liquids or refined products in the markets served by the pipeline; changes in the availability of products for gathering, transportation, storing, processing or sale due to natural declines in reserves and production in the supply areas serviced by the companies’ facilities; sharp decreases in crude oil or natural gas prices that cause producers to curtail production or reduce capital spending for exploration activities; and environmental regulation. Demand for gasoline, which accounts for a substantial portion of refined product transportation, depends on price, prevailing economic conditions in the markets served, and demographic and seasonal factors. Gathering and processing pipeline companies are subject to many risks, including declines in production of crude oil and natural gas fields which utilize their gathering and processing facilities as a way to market the crude oil and gas, prolonged depression in the price of natural gas or crude oil, which curtails production due to lack of drilling activity, and declines in the prices of natural gas liquids and refined petroleum products resulting in lower processing or refining margins. In addition, the development of, demand for, and/or supply of competing forms of energy may negatively impact the revenues of these companies.

Non-U.S. Securities Risk.    Investments in securities of non-U.S. issuers involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.

Large-Cap, Mid-Cap and Small-Cap Companies Risk.    The Fund’s investment in companies with large market capitalizations is subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Securities of mid-cap and small-cap companies may be more volatile and less liquid than the securities of large-cap companies.

MLP Risk.    MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.

The Fund’s investment strategies depend in part on MLPs generally being treated as partnerships for U.S. federal income tax purposes. If any of the MLPs owned by the Fund were treated as corporations for U.S. federal income tax purposes, it could result in a reduction in the value of your investment in the Fund and lower distributions.

The Fund expects to receive cash distributions each year from certain MLPs that exceed the net taxable income allocated to the Fund from such MLPs for such year, and, as a result, the Fund may recognize larger taxable gains (or smaller losses) with respect to such MLPs when it disposes of its interests in such MLPs. If you hold shares in the Fund when such gains or losses are recognized, you may be required to pay tax on one or more Fund distributions, potentially at ordinary income tax rates, even though you may not have economically benefited from the associated MLP cash distributions.

Liquidity Risk.    The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities at an advantageous price or in a timely manner. Illiquid or restricted securities cannot be sold immediately because of statutory and contractual restrictions on resale.

Tracking Error Risk.    There is no guarantee that the Fund will achieve a high degree of correlation to the Underlying Index and therefore achieve its investment objective. The Fund’s return may not match the return of its Underlying Index for a number of reasons, including differences between the securities held in the Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs, the Fund’s holding of cash, differences in timing of the accrual of distributions, changes to the Underlying Index or the need to meet various new or existing regulatory requirements. Consequently, the performance of the Fund may diverge from that of its Underlying Index. This risk may be heightened during times of increased market volatility or other unusual market conditions, or due to delays of the Fund in purchasing and selling securities. Tracking error also may result because the Fund incurs fees and expenses, while the Underlying Index does not.

Absence of Active Trading Market Risk.    Although shares of the Fund are listed for trading on one or more stock exchanges, there can be no assurance that an active trading market for such shares will develop or be maintained. There can be no assurance that the requirements necessary to maintain the listing or trading of Fund shares will continue to be met or will remain unchanged.

Trading Risks.    The Fund faces numerous trading risks, including disruption in the creation/redemption process of the Fund and losses from trading in the secondary markets. Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or other reasons or due to extraordinary market volatility pursuant to “circuit breaker” rules on the Exchange or market. Additionally, an exchange or market may also close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

Methodology Risks.    The Index Provider relies on various sources of information to assess the criteria of issuers included in the Underlying Index, including information that may be based on assumptions and estimates. Neither the Fund nor the Index Provider can offer assurances that the Underlying Index’s calculation methodology or sources of information will provide an accurate assessment of included issuers or that the included issuers will provide the Fund with the market exposure it seeks.

AI Infrastructure Risk.    The Fund’s strategy of emphasizing investments in AI infrastructure companies means that the performance of the Fund will be closely tied to the performance of one or more industries that are expected to benefit from the growth of AI-capable data centers and related technology and energy infrastructure. Investing in companies that are expected to benefit from the same macro theme means that some of the Fund’s investments may be similarly affected by certain market, economic, political, or social developments. The risks of emphasizing AI-capable data centers and companies that provide critical infrastructure to such companies include a slower adoption rate of AI that results in lower capital spending on AI infrastructure; changes in the pace or focus of AI infrastructure spending; the development of large language models that require less AI infrastructure for similar output; and the emergence of alternative energy technology that generates reliable electricity.

Technology Infrastructure Concentration Risk.    Companies in the technology infrastructure sector are subject to many risks that can negatively impact the revenues and viability of companies in this sector, including, but not limited to risks associated with emerging technology that renders existing products or services obsolete, reliance on outdated technology, intellectual property theft, supply chain disruption, vulnerabilities to third-party vendors and suppliers, business interruption, difficulty in retaining skilled talent, and regulatory compliance.

Counterparty Risk.    Counterparty risk is the risk that the other party or parties to an agreement or a participant to a transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.

Covered Call Option Risk.    If the Fund writes a covered call option, during the option’s life the Fund gives up the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. Moreover, the writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option.

Non-Diversified Fund Risk.    Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Foreign Securities Risk.    Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.

ADR Risk.    ADRs are generally subject to the same risks as the foreign securities because their values depend on the performance of the underlying foreign securities. ADRs may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. Holders of unsponsored ADRs generally bear all the costs of such depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications

received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs. As a result, there may not be a correlation between such information and the market values of unsponsored ADRs.

Mid-Cap and Small-Cap Companies Risk.    Mid-cap and small-cap companies may not have the management experience, financial resources, product or business diversification and competitive strengths of large cap companies. Therefore, these securities may have more price volatility and be less liquid than the securities of larger, more established companies.

Shares May Trade at Prices Different than NAV Per Share.    Disruptions to creations and redemptions, the existence of extreme market volatility or potential lack of an active trading market for shares of the Fund may result in shares trading at a significant premium or discount to NAV. If a shareholder purchases shares when the market price is at a premium to the NAV or sells shares when the market price is at a discount to the NAV, the shareholder may sustain losses.

Market Maker Risk.    The Fund faces numerous market risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and in greater than normal intraday bid-ask spreads for Fund shares.

Cybersecurity Risk.    Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses. Such cyber networks might in some circumstances be at risk of cyber-attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.

Illiquid Investments Risk.    The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities or close call option positions at an advantageous price or in a timely manner. Illiquid investments may include restricted securities that cannot be sold immediately because of statutory and contractual restrictions on resale.

Tax Risk.    The Fund has elected to be, and intends to qualify each year for treatment as, a “regulated investment company” under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). To maintain qualification for federal income tax purposes as a regulated investment company under the Code, the Fund must meet certain source-of-income, asset diversification and annual distribution requirements, as discussed in detail below under “Tax Consequences.”

General Business Risk.    We are subject to all of the business risks and uncertainties associated with any business, including the risk that we will not achieve our investment objectives and that the value of an investment in our securities could decline substantially and cause you to lose some or all of your investment.

Concentration Risk.    The Fund’s strategy of concentrating its assets in the group of industries comprising the power and energy infrastructure sectors means that the performance of the Fund will be closely tied to the performance of these particular market sectors. Therefore, a downturn in the power and energy infrastructure sectors would have a larger impact on the Fund than on an investment company that does not concentrate in these sectors. Specific risks of investing in the power and energy infrastructure sectors include the following: (1) interest rate risk, (2) credit rating downgrade risk, (3) terrorism and natural disasters risk, (4) climate change regulation risk, (5) operating risk, (6) power infrastructure company risk, and (7) energy infrastructure company risk. The Fund’s concentrations in these investments may present more risk than if we were broadly diversified over numerous industries and sectors of the economy.

Energy Infrastructure Company Risk.    Companies operating in the energy infrastructure sector also are subject to additional risks, including: (1) pipeline company risk, (2) gathering and processing company risk, (3) propane company risk, (4) supply and demand risk, (5) price volatility risk, (6) competition risk, and (7) regulatory risk. To the extent that any of these risks materialize for a company whose securities are in our portfolio, the value of these securities could decline and our net asset value and share price would be adversely affected.

Non-U.S. Securities Risk.    Investments in the securities of non-U.S. issuers may involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including different accounting, auditing and financial standards, less government supervision and regulation, additional tax withholding and taxes, difficulty enforcing rights in foreign countries, less publicly available information, difficulty effecting transactions, higher expenses, and exchange rate risk.

Rule 144A Securities Risk.    Rule 144A provides an exemption from the registration requirements of the Securities Act of 1933 (the “1933 Act”), for the resale of certain restricted securities to qualified institutional buyers, such as the Fund. An insufficient number of qualified institutional buyers interested in purchasing Rule 144A-eligible securities held by us, however, could affect adversely the marketability of certain Rule 144A securities, and we might be unable to dispose of such securities promptly or at reasonable prices. In addition, if for any reason we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the fair value at which we previously recorded these investments.

Investment Grade Fixed Income Securities Risk.    We may invest a portion of our assets in fixed income securities rated “investment grade” by nationally recognized statistical rating organizations (“NRSROs”) or judged by our Adviser, to be of comparable credit quality. Although we do not intend to do so, we may invest up to 100% in such securities. Investment grade fixed income securities are rated Baa3 or higher by Moody’s Investors Service, Inc. (“Moody’s”), BBB- or higher by Standard & Poor’s Ratings Services (“S&P”), or BBB- or higher by Fitch, Inc. (“Fitch”). Despite being considered to be subject to fewer risks than non-investment grade fixed income securities, commonly referred to as “junk bonds,” investment grade fixed income securities are, in fact, subject to risks, including volatility, credit risk and risk of default, sensitivity to general economic or industry conditions, potential lack of resale opportunities (illiquidity), and additional expenses to seek recovery from issuers who default.

Capital Markets Risk.    Global financial markets and economic conditions have been, and may continue to be, volatile due to a variety of factors, including significant write-offs in the financial services sector. Concerns about the general stability of financial markets and specifically the solvency of lending counterparties, may impact the cost of raising capital from the credit markets through increased interest rates, tighter lending standards, difficulties in refinancing debt on existing terms or at all and reduced, or in some cases ceasing to provide, funding to borrowers. In addition, lending counterparties under existing revolving credit facilities and other debt instruments may be unwilling or unable to meet their funding obligations. If funding is not available when needed, or is available only on unfavorable terms, companies may not be able to meet obligations as they come due.

Non-Diversification Risk.    We are registered as a non-diversified, open-end management investment company under the 1940 Act. Accordingly, there are no regulatory limits under the 1940 Act on the number or size of securities that we hold, and we may invest more assets in fewer issuers compared to a diversified fund. However, in order to qualify as a RIC for federal income tax purposes, we must meet certain diversification requirements.

Competition Risk.    There are a number of alternatives to us as vehicles for investment in a portfolio of companies operating primarily in the power and energy infrastructure sectors, including publicly traded investment companies, structured notes, private funds, open-end funds and indexed products. These competitive conditions may adversely impact our ability to meet our investment objectives.

Legal and Regulatory Change Risk.    The regulatory environment for open-end companies is evolving, and changes in the regulation of open-end companies may adversely affect the value of our investments or our ability to pursue our trading strategy. The effect of any future regulatory change on us could be substantial and adverse.

Authorized Participant Concentration Risk.    Only an authorized participant may engage in creation or redemption transactions directly with the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for Creation Units.

Market Maker Risk.    The Fund faces numerous market risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and in greater than normal intraday bid-ask spreads for Fund shares.

Share Price Risk.    Disruptions to creations and redemptions, bid-ask spreads, the existence of extreme market volatility or potential lack of an active trading market for shares of the Fund may result in shares trading at a significant premium or discount to net asset value (“NAV”). Due to the bid-ask spread, or if the Fund’s shares are otherwise trading at a premium or discount to NAV, investors may receive more or less than NAV when buying or selling their shares on an exchange.

Pandemic and Epidemic Risk.    Widespread disease, including pandemics and epidemics, have been and can be highly disruptive to economies and markets, adversely impacting individual companies, sectors, industries, markets, currencies, interest and inflation rates, credit ratings, investor sentiment, and other factors affecting the value of the Fund’s investments. These disruptions could prevent the Fund from executing advantageous investment decisions in a timely manner and negatively impact its ability to achieve its investment objectives. Any such event(s) could have a significant adverse impact on the value and risk profile of the Fund.

Valuation Risk.    The fair value of certain of our investments may not be readily determinable. The fair value of these securities will be determined pursuant to methodologies established by our Board of Trustees (the “Board” or the “Trust Board”). Our determination of fair value may differ materially from the values that would have been used if a ready market for these securities had existed.

Energy Sector Risk.    Under normal circumstances, the Fund concentrates its investments in the energy sector, which includes a number of risks, including the following: supply and demand risk, depletion and exploration risk, marine transportation companies risk, regulatory risk, commodity pricing risk, weather risk, cash flow risk, affiliated party risk, catastrophe risk, acquisition risk, and natural resources sector risk. For example, decreases in oil prices may have a substantial impact on the prices of publicly-traded equity securities of energy companies.

Credit Risk.    If an issuer or guarantor of a debt security held by the Fund or a counterparty to a financial contract with the Fund defaults or is downgraded or is perceived to be less creditworthy, or if the value of the assets underlying a security declines, the value of the Fund’s portfolio will typically decline.

Covered Call Option Risk.    If the Fund writes a covered call option, during the option’s life the Fund gives up the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the strike price of the call, but retains the risk of loss should the price of the underlying security decline. Moreover, the writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option.

Concentration Risk.    The Fund’s strategy of focusing its investments in the group of industries comprising the energy sector means that the performance of the Fund will be closely tied to the performance of those industries. The Fund’s focus in these industries presents more risk than if it were broadly diversified over numerous industries and sectors of the economy. An inherent risk associated with any investment focus is that the Fund may be adversely affected if its investments perform similarly in response to market, economic or political events.

Renewable Energy Company Risk.    Renewable energy companies are dependent upon factors such as available solar resource, wind conditions, weather conditions and power generating equipment performance that may significantly impact the performance of such companies. Solar, wind and weather conditions generally have natural variations from season to season and from year to year and may also change permanently because of climate change or other factors. Solar and wind energy is highly dependent on weather conditions and, in particular, on available solar and wind conditions. Moreover, power generating equipment used generally by renewable energy companies is accompanied by the attendant costs of maintaining such equipment while in use and subject to risks of obsolescence associated with emerging and disruptive new technologies.

Non-Diversified Fund Risk.    Because the Fund is “non-diversified” and may invest a greater percentage of its assets in the securities of a single issuer, a decline in the value of an investment in a single issuer could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio.

Foreign Securities Risk.    Investments in securities of foreign companies involve risks not ordinarily associated with investments in securities and instruments of U.S. issuers, including risks relating to political, social and economic developments abroad, differences between U.S. and foreign regulatory and accounting requirements, tax risks, and market practices, as well as fluctuations in foreign currencies.

ADR Risk.    ADRs are generally subject to the same risks as the foreign securities because their values depend on the performance of the underlying foreign securities. ADRs may be purchased through “sponsored” or “unsponsored” facilities. A sponsored facility is established jointly by the issuer of the underlying security and a depositary, whereas a depositary may establish an unsponsored facility without participation by the issuer of the depositary security. Holders of unsponsored ADRs generally bear all the costs of such depositary receipts, and the issuers of unsponsored ADRs frequently are under no obligation to distribute shareholder communications received from the company that issues the underlying foreign securities or to pass through voting rights to the holders of the ADRs. As a result, there may not be a correlation between such information and the market values of unsponsored ADRs.

Interest Rate Risk.    MLPs and other higher yield securities historically have shown sensitivity to interest rate movements. In an increasing interest rate environment, these types of securities may experience upward pressure on their yields in order to stay competitive with other interest rate sensitive securities. Also, significant portions of the market value of MLPs and other higher yield securities may be based upon their current yields. Accordingly, the prices of these securities may be sensitive to fluctuations in interest rates and may decline when interest rates rise.

MLP Risk.    MLPs are subject to many risks, including those that differ from the risks involved in an investment in the common stock of a corporation. Holders of MLP units have limited control and voting rights on matters affecting the partnership and are exposed to a remote possibility of liability for all of the obligations of that MLP. Holders of MLP units are also exposed to the risk that they will be required to repay amounts to the MLP that are wrongfully distributed to them. In addition, the value of the Fund’s investment in an MLP will depend largely on the MLP’s treatment as a partnership for U.S. federal income tax purposes. Furthermore, MLP interests may not be as liquid as other more commonly traded equity securities.

Capital Markets Risk.    MLPs normally pay out the majority of their operating cash flows to partners. Therefore, MLPs and other issuers in which the Fund invests may rely significantly on capital markets for access to equity and debt financing in order to fund organic growth projects and acquisitions. Should market conditions limit issuers’ access to capital markets, their distribution growth prospects could be at risk.

Below Investment Grade Debt Securities Risk.    Investments in below investment grade debt securities and unrated securities of similar credit quality as determined by the Adviser (commonly known as “junk bonds”) involve a greater risk of default and are subject to greater levels of credit and liquidity risk. Below investment grade debt securities have speculative characteristics and their value may be subject to greater fluctuation than investment grade debt securities.

Liquidity Risk.    The Fund may not be able to sell some or all of the investments that it holds due to a lack of demand in the marketplace or other factors such as market turmoil, or if the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs it may only be able to sell those investments at a loss. In addition, the reduction in dealer market-making capacity in the fixed income markets that has occurred in recent years has the potential to decrease the liquidity of the Fund’s investments. Illiquid assets may also be difficult to value.

Authorized Participant Concentration Risk.    Only an authorized participant may engage in creation or redemption transactions directly with the Fund. A limited number of institutions act as authorized participants for the Fund. However, participants are not obligated to make a market in the Fund’s shares or submit purchase and redemption orders for Creation Units. To the extent that these institutions exit the business, reduce their role or are unable to proceed with creation and/or redemption orders and no other authorized participant steps forward to create or redeem, the Fund’s shares may trade at a premium or discount to the Fund’s net asset value and possibly face delisting and the bid/ask spread on the Fund’s shares may widen.

Market Maker Risk.    The Fund faces numerous market risks, including the potential lack of an active market for Fund shares due to a limited number of market markers. Decisions by market makers or authorized participants to reduce their role or step away from these activities in times of market stress could inhibit the effectiveness of the arbitrage process in maintaining the relationship between the underlying values of the Fund’s portfolio securities and the Fund’s market price. The Fund may rely on a small number of third-party market makers to provide a market for the purchase and sale of shares. Any trading halt or other problem relating to the trading activity of these market makers could result in a dramatic change in the spread between the Fund’s net asset value and the price at which the Fund’s shares are trading on the exchange, which could result in a decrease in value of the Fund’s shares. This reduced effectiveness could result in Fund shares trading at a discount to net asset value and in greater than normal intraday bid-ask spreads for Fund shares.

Cybersecurity Risk.    Investment advisers, including the Adviser, must rely in part on digital and network technologies (collectively “cyber networks”) to conduct their businesses. Such cyber networks might in some circumstances be at risk of cyber-attacks that could potentially seek unauthorized access to digital systems for purposes such as misappropriating sensitive information, corrupting data, or causing operational disruption.

Illiquid Investments Risk.    The Fund may be exposed to liquidity risk when trading volume, lack of a market maker, or legal restrictions impair the Fund’s ability to sell particular securities or close call option positions at an advantageous price or in a timely manner. Illiquid investments may include restricted securities that cannot be sold immediately because of statutory and contractual restrictions on resale.

Tax Risk.    The Fund has elected to be, and intends to qualify each year for treatment as, a “regulated investment company” under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). To maintain qualification for federal income tax purposes as a regulated investment company under the Code, the Fund must meet certain source-of-income, asset diversification and annual distribution requirements, as discussed in detail below under “Tax Consequences.”
