A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the Example, affect the Fund’s performance. Because the Fund is newly organized, portfolio turnover information is not yet available. Principal Investment Strategies Overview The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. Index Overview The Index is a rules-based thematic index developed by MarketVector Indexes GmbH (the "Index Provider") that seeks to track the performance of publicly traded companies involved in the industrial gas (including helium), cryogenics and specialty gas industry. For purposes of the Index, eligible companies generally derive at least 50% of their revenues (25% for current Index constituents) from one or more of the following activities: <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Industrial and specialty gases including electronic gases, rare gases, high-purity gases, and gas mixtures;</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Cryogenics and liquefaction, and/or</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Gas equipment, systems, and services, including air separation, compression, vacuum, purification, storage, transfer, distribution, and gas-related engineering services.</td></tr></table> Companies are classified as “Core Helium and Strategic Gas Companies” if they meet the applicable revenue criteria and have revenue exposure to helium. Companies that meet the applicable revenue criteria but do not have revenue exposure to helium are classified as “Non-Core Helium and Strategic Gas Companies.” Following thematic screening, companies generally must satisfy minimum market capitalization, liquidity, free-float and exchange eligibility requirements established by the Index methodology before becoming eligible for selection. Eligible securities generally include common stocks and substantially equivalent equity securities (e.g., American Depositary Receipts, Global Depositary Receipts, and preference shares). The Index generally targets 10 constituents. Eligible companies are ranked based on free-float market capitalization, with Core Helium and Strategic Gas Companies ranked ahead of Non-Core Helium and Strategic Gas Companies. At each quarterly reconstitution, companies ranked among the top eight remain eligible for inclusion, while the remaining constituent positions are generally filled from among the highest-ranked existing Index constituents ranked between ninth and fifteenth, which is intended to reduce unnecessary constituent turnover.free-ranked ahead of Non-Core Helium and Strategic Gas Companies. At the initial construction of the Index, the 10 highest-ranked eligible companies are selected. At subsequent quarterly reviews, companies ranked among the top eight remain eligible for inclusion, and the remaining two components are selected from the highest ranking current index components ranked between ninth and fifteenth, which is intended to reduce unnecessary constituent turnover. The Index is reconstituted and rebalanced quarterly. Following each rebalance, Index constituents are generally equally weighted, subject to liquidity-based weighting limitations. To the extent the Index concentrates its investments in a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent. Please see the prospectus section titled “Additional Information About the Fund” for more detailed information about the Index’s methodology. The Fund’s Investment Strategy Under normal circumstances, the Fund will invest at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in component securities that make up the Index or investments that provide indirect exposure to such securities. The Fund attempts to invest all, or substantially all, of its assets in, or obtain indirect economic exposure to, the component securities that make up the Index. The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest (directly or indirectly) in all of the component securities of the Index. Because the Index consists of a relatively small number of component securities, the Fund may be limited in its ability to invest directly in Index component securities to the extent necessary to comply with applicable requirements of the 1940 Act, as well as the asset diversification requirements applicable to regulated investment companies under Subchapter M of the Internal Revenue Code. Accordingly, the Fund may obtain exposure to the Index, in whole or in part, through derivative instruments, including total return swaps referencing the Index or one or more of its component securities, in order to seek to maintain economic exposure to the Index while complying with applicable regulatory requirements. The Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Adviser believes it is in the best interests of the Fund. For example, representative sampling may be used when replicating the Index involves practical difficulties or substantial costs, an Index component becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index. Subject to the Fund’s 80% policy, the Fund may invest in securities or other investments not included in the Index where the Adviser determines such investments are appropriate. Additionally, the Fund may attempt to replicate the index “synthetically” through the use of derivatives, including options and total return swaps. In addition to supporting the Fund’s efforts to track the Index, these investments may be made when the Adviser believes they will enhance performance or otherwise benefit the Fund. For example, the Fund may invest in non-Index securities in connection with corporate actions or changes to the Index (including reconstitutions, additions, and deletions), as well as for liquidity, cash management, or other portfolio management purposes. As noted above, the Fund may utilize listed options to obtain synthetic exposure to portfolio securities. The Fund primarily employs short-dated (generally one month or less), in-the-money call options to replicate the performance of underlying equity securities. The Fund may also utilize other option strategies designed to achieve similar synthetic exposure, including purchasing call options and selling put options with identical strike prices. The Fund will invest in listed equity securities, which may include common stocks, business trust shares, and other equity investments or ownership interests in business enterprises. The Fund may invest in ADRs, GDRs and preference shares to approximately the extent such securities are included in the Index. The Fund may also invest in cash, cash equivalents, or short-term instruments, including money market funds, to manage liquidity, collateralize positions, or temporarily hold assets pending investment. The Fund is classified as “non-diversified,” which means the Fund may invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. Under normal circumstances, the Fund will invest at least 80% of the Fund’s net assets (plus borrowings for investment purposes) in component securities that make up the Index or investments that provide indirect exposure to such securities. The Fund may not achieve its investment objective and there is a risk that you could lose all of your money invested in the Fund. Specialty Gas Industry Risk. The Specialty Gas industry includes companies engaged in gas exploration and production (including integrated gas exploration), gas refining and marketing, and gas storage and transportation. The prices of the securities of companies in the Specialty Gas industry may fluctuate widely due to supply and demand for a specific product or service, the price of gas, exploration and production spending, world events, and economic conditions. Natural disasters and changes in exchange rates and interest rates also may affect companies in the Specialty Gas Industry. The regulatory environment, taxation policies, and the economies of the key helium and specialty gas production countries also may affect the prices of the securities in the Specialty Gas industry. Legislative or regulatory changes and increased government supervision also may affect companies in the Specialty Gas industry. Foreign Investment Risk: The Fund may invest in foreign companies. Such investments involve certain risks not involved in domestic investments and may experience more rapid and extreme changes in value than investments in securities of U.S. companies. Financial markets in foreign countries often are not as developed, efficient, or liquid as financial markets in the United States, and therefore, the prices of non-U.S. securities and instruments can be more volatile. In addition, the Fund will be subject to risks associated with adverse political and economic developments in foreign countries, which may include the imposition of economic sanctions. Generally, there is less readily available and reliable information about non-U.S. issuers due to less rigorous disclosure or accounting standards and regulatory practices. <div id="xdx_A83_eoef--RiskTextBlock_hoef--RiskAxis__custom--DepositaryReceiptRiskMember_zLsJ61cj6Hhe"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; margin-top: 0pt; margin-bottom: 0pt"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities and give rise to certain additional risks. Depositary receipts listed on U.S. or foreign 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.</td></tr></table> Equity Market Risk. Common stocks, such as those held by the Fund, 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 specific issuers. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. Focused Portfolio Risk. The Fund will hold a relatively focused portfolio that may contain exposure to the securities of fewer issuers than the portfolios of other ETFs. Holding a relatively focused portfolio may increase the risk that the value of the Fund could go down because of the poor performance of one or a few investments. Index Strategy Risk. The Fund’s strategy is linked to an Index maintained by the Index Provider that exercises complete control over the Index. The Index Provider may delay or add a rebalance date, which may adversely impact the performance of the Fund and its correlation to the Index. In addition, there is no guarantee that the methodology used by the Index Provider to identify constituents for the Index will achieve its intended result or positive performance. Errors in Index data, Index computations or the construction of the Index in accordance with its methodology may occur from time to time and may not be identified and/or corrected for a period of time or at all, which may have an adverse impact on the Fund. Data Risk. The composition of the Index is heavily dependent on information and data supplied by third parties (“Data”). When Data proves to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to also reflect the errors. Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index. Tracking Error Risk. While the Fund generally seeks to track the performance, before fees and expenses, of the Index, 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’s investment exposure will be concentrated in (or substantially exposed to) the same industry or group of industries to the extent the Index is so concentrated. In such event, the value of Shares may rise and fall more than the value of shares that invest in securities of companies in a broader range of industries. Please see “Specialty Gas Industry Risk” disclosure above. Management Risk. The risk that the investment techniques and risk analyses applied by the investment adviser will not produce the desired results and that legislative, regulatory, or tax developments may affect the investment techniques available to the investment adviser and the individual portfolio manager in connection with managing the Fund. There is no guarantee that the investment objective of the Fund will be achieved. <p id="xdx_A84_eoef--RiskTextBlock_hoef--RiskAxis__custom--RisksRelatedToChangesInGovernmentPoliciesAndInstitutionsMember_zTNIQEzaqw02" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Risks Related to Changes in Government Policies and Institutions. The U.S. government has recently made, and may continue to make from time to time, significant changes to established, and in some cases longstanding, policies and institutions of the United States federal government, including the restructuring of the United States’ trade relationships, imposition of tariffs on products imported from foreign markets, reducing government investment, and downsizing or dismantling of government agencies. Such changes may have immediate and/or longstanding effects on the economies of the United States, its trade partners, and/or its allies. There could be a wide range of consequences that are difficult or impossible to predict from such actions. Such consequences may include a decrease in regulatory oversight of certain highly regulated industries (banking, financial services, data security, drug and medical device development, and energy), an increase in regulatory backlog leading to significantly slower regulatory approval processes, uncertainty with respect to the authority of certain agencies or their personnel, the inability of the federal government and its agencies to maintain the security of personal data of United States citizens and/or of other digital assets. The business and prospects of companies that do business with the government or which rely on government funding may be materially and adversely affected. This may include the Fund and/or prospective issuers held in the Fund’s investment portfolio. Derivatives Risk. Derivatives are financial instruments that derive value from the underlying reference asset or assets, such as stocks, bonds, or funds (including ETFs), interest rates or indexes. The Fund’s investments in derivatives may pose risks in addition to, and greater than, those associated with directly investing in securities or other ordinary investments, including risk related to the market, imperfect correlation with underlying investments or the Fund’s other portfolio holdings, higher price volatility, lack of availability, counterparty risk, liquidity, valuation and legal restrictions. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of derivatives may result in larger losses or smaller gains than directly investing in securities. When the Fund uses derivatives, there may be an imperfect correlation between the value of the underlying reference asset and the derivative, which may prevent the Fund from achieving its investment objective. Because derivatives often require only a limited initial investment, the use of derivatives may expose the Fund to losses in excess of those amounts initially invested. In addition, the Fund’s investments in derivatives are subject to the following risks: <div id="xdx_A84_eoef--RiskTextBlock_hoef--RiskAxis__custom--OptionsContractsMember_zklZ92PeRrka"></div> Options Contracts. The use of options contracts involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, including the anticipated volatility, which are affected by fiscal and monetary policies and by national and international politics, changes in the actual or implied volatility or the reference asset, the time remaining until the expiration of the option contract and economic events. The Fund may experience substantial downside from specific option positions and certain option positions held by the Fund may expire worthless. The options held by the Fund are exercisable at the strike price on their expiration date. As an option approaches its expiration date, its value typically increasingly moves with the value of the underlying instrument. However, prior to such date, the value of an option generally does not increase or decrease at the same rate as the underlying instrument. There may at times be an imperfect correlation between the movement in values options contracts and the underlying instrument, and there may at times not be a liquid secondary market for certain options contracts. The value of the options held by the Fund will be determined based on market quotations or other recognized pricing methods. Additionally, as the Fund’s options contracts are exercised or expire it may enter into new options contracts, a practice referred to as “rolling.” If the expiring options contracts do not generate proceeds enough to cover the cost of entering into new options contracts, the Fund may experience losses. Swap Agreements. The use of swap transactions is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Whether the Fund will be successful in using swap agreements to achieve its investment goal depends on the ability of the Adviser to structure such swap agreements in accordance with the Fund’s investment objective and to identify appropriate counterparties. If the Adviser is unable to enter into swap agreements that provide the desired synthetic exposure to the underlying security, the Fund may not meet its stated investment objective. Additionally, any financing, transaction, or other costs associated with using swap transactions may have the effect of lowering the Fund’s return. The swap agreements in which the Fund invests are generally traded in the over-the-counter market, which generally has less transparency than exchange-traded derivative instruments. In a standard swap transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined reference assets, securities, or instruments. The gross return to be exchanged or “swapped” between the parties is calculated based on a notional amount or the return on or change in value of a particular dollar amount invested in the reference asset. If the underlying security experiences a significant price movement that causes a material change in the Fund’s net assets, the terms of a swap agreement between the Fund and its counterparty may permit the counterparty to close out the swap transaction with the Fund. In that event, the Fund may be unable to enter into another swap agreement or invest in other derivatives to maintain exposure consistent with its investment objective. This may temporarily reduce the Fund’s ability to maintain its intended level of synthetic exposure until replacement transactions can be established. Certain of the swap agreements entered into by the Fund may be unfunded total return swaps, pursuant to which the Fund does not make an initial investment of the full notional amount of the swap. As a result, the Fund is exposed to the risk that its counterparty will be unable to meet its obligations under the swap agreement, and the Fund’s exposure to a counterparty generally equals the net amount owed to the Fund based on the daily change in value of the reference asset. In the event of a counterparty default or insolvency, the Fund may incur losses in excess of the collateral, if any, posted by the counterparty, and the timing and amount of any recovery may be uncertain. In addition, the use of unfunded swap agreements may create economic leverage for the Fund, which may magnify gains and losses and increase the volatility of the Fund’s returns. Equity Total Return Swaps. A total return swap (also sometimes referred to as a synthetic equity swap or “contract for difference” when written with respect to an equity security or basket of equity securities) is an agreement between two parties under which the parties agree to make payments to each other so as to replicate the economic consequences that would apply had a purchase or short sale of the underlying reference instrument or index thereof taken place. For example, one party agrees to pay the other party the total return earned or realized on the notional amount of an underlying equity security and any dividends declared with respect to that equity security. In return the other party makes payments, typically at a floating rate, calculated based on the notional amount. Counterparty Risk. To the extent contemplated by its investment strategy, the Fund may use derivative instruments, such as options, swaps, futures contracts and other instruments, to obtain or manage investment exposure. Derivatives may be subject to counterparty risk, meaning the risk that a counterparty, clearing member or clearing house will be unwilling or unable to perform its obligations to the Fund due to bankruptcy, insolvency, financial distress, operational failure or other default. If a counterparty or clearing member defaults, the Fund may lose the expected benefit of the transaction, experience delays or costs in recovering collateral or other amounts owed to it, or be required to enter into replacement transactions on less favorable terms, if at all. The Fund also may be unable to implement its investment strategy effectively if suitable counterparties or clearing members are unavailable. ETF Risks <p id="xdx_A8A_eoef--RiskTextBlock_hoef--RiskAxis__custom--AuthorizedParticipantsMarketMakersAndLiquidityProvidersConcentrationRiskMember_z15iU7mS4xul" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in; text-align: justify">Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that are authorized to purchase and redeem Shares directly from the Fund (known as “Authorized Participants” or “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. Cash Redemption Risk. The Fund’s investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. For example, the Fund may not be able to redeem in-kind certain securities held by the Fund (e.g., derivative instruments). In such a case, the Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used. By paying out higher annual capital gain distributions, investors may be subjected to increased capital gains taxes. The costs associated with cash redemptions may include brokerage costs that the Fund may not have incurred if it had made the redemptions in-kind. These costs could be imposed on the Fund, decreasing its NAV, to the extent these costs are not offset by a transaction fee payable by an authorized participant. Costs of Buying or Selling Shares. Buying or selling Shares involves certain costs, including brokerage commissions, other charges imposed by brokers, and bid-ask spreads. The bid-ask spread represents the difference between the price at which an investor is willing to buy Shares and the price at which an investor is willing to sell Shares. The spread varies over time based on the Shares’ trading volume and market liquidity. The spread is generally lower if Shares have more trading volume and market liquidity and higher if Shares have little trading volume and market liquidity. Due to the costs of buying or selling Shares, frequent trading of Shares may reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments. <p id="xdx_A88_eoef--RiskTextBlock_hoef--RiskAxis__custom--SharesMayTradeAtPricesOtherThanNavMember_zC58R44Zp0d8" style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0 0pt 0.25in; text-align: justify">Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. Trading. Although Shares are listed on a national securities exchange, such as The Nasdaq Stock Market, LLC (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares. This adverse effect on liquidity for the Fund’s shares may lead to wider bid-ask spreads and differences between the market price of the Fund’s shares and the underlying value of the shares. Liquidity Risk. In certain circumstances, such as the disruption of the orderly markets for the financial instruments in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the financial instruments in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, health crises, natural disasters, excessive volatility, new legislation, or regulatory changes inside or outside of the U.S. These situations may have an impact on the liquidity of the Fund’s own shares. Economic and Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. Securities in the Fund’s portfolio may underperform in comparison to securities in the general financial markets, a particular financial market, or other asset classes, due to a number of factors, including inflation (or expectations for inflation), deflation (or expectations for deflation), interest rates, global demand for particular products or resources, market instability, financial system instability, debt crises and downgrades, embargoes, tariffs, sanctions and other trade barriers, regulatory events, other governmental trade or market control programs and related geopolitical events. In addition, the value of the Fund’s investments may be negatively affected by the occurrence of global events such as war, terrorism, environmental disasters, natural disasters or events, country instability, and infectious disease epidemics or pandemics. The imposition by the U.S. of tariffs on goods imported from foreign countries and reciprocal tariffs levied on U.S. goods by those countries also may lead to volatility and instability in domestic and foreign markets. High Portfolio Turnover Risk. The Fund may actively and frequently trade all or a significant portion of the Fund’s holdings as it seeks to track the Index. A high portfolio turnover rate increases transaction costs, which may increase the Fund’s expenses. Frequent trading may also cause adverse tax consequences for investors in the Fund due to an increase in short-term capital gains. Liquidity Risk. Some securities held by the Fund may be difficult to sell or be illiquid, particularly during times of market turmoil. Markets for securities or financial instruments could be disrupted by a number of events, including, but not limited to, an economic crisis, natural disasters, epidemics/pandemics, new legislation or regulatory changes inside or outside the United States. Illiquid securities may be difficult to value, especially in changing or volatile markets. If the Fund is forced to sell an illiquid security at an unfavorable time or price, the Fund may be adversely impacted. There is no assurance that a security that is deemed liquid when purchased will continue to be liquid. Market illiquidity may cause losses for the Fund. Market Capitalization Risk. <div id="xdx_A85_eoef--RiskTextBlock_hoef--RiskAxis__custom--LargecapitalizationInvestingMember_zq3LX7w3djUl"></div> <table cellpadding="0" cellspacing="0" style="font: 10pt Times New Roman, Times, Serif; width: 100%; border-collapse: collapse"> <tr style="vertical-align: top"> <td style="width: 38px"> </td> <td style="width: 38px">●</td> <td style="text-align: justify">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.

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 small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities or large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.</td></tr> </table> Money Market Instrument Risk. The Fund may use a variety of money market instruments for cash management purposes, including money market funds, depositary accounts and repurchase agreements. Repurchase agreements are contracts in which a seller of securities agrees to buy the securities back at a specified time and price. Repurchase agreements may be subject to market and credit risk related to the collateral securing the repurchase agreement. Money market instruments, including money market funds, may lose money through fees or other means. New Fund Risk. The Fund is a recently organized management investment company with no operating history. As a result, prospective investors do not have a track record or history on which to base their investment decisions. Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a smaller number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a smaller number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. Operational Risk. The Fund is subject to risks arising from various operational factors, including, but not limited to, human error, processing and communication errors, errors of the Fund’s service providers, counterparties or other third-parties, failed or inadequate processes and technology or systems failures. The Fund relies on third-parties for a range of services, including custody. Any delay or failure relating to engaging or maintaining such service providers may affect the Fund’s ability to meet its investment objective. Although the Fund and Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. Newly Public Company Risk. The Fund may obtain exposure to publicly traded companies that have recently completed an initial public offering (“IPO”), as well as operating companies resulting from completed SPAC business combinations, to the extent such companies are included in the Index. Companies that have recently become publicly traded may be unseasoned and may have limited trading histories, track records of reporting to investors, and research coverage. Their securities may experience significant price volatility and may be subject to greater liquidity risk. In addition, significant holdings by venture capital, private equity or other pre-public investors may become eligible for sale following the expiration of applicable lock-up periods, which may result in increased volatility or downward pressure on the market price of such securities. Tax Risk. The Fund intends to elect and to qualify each year to be treated as a regulated investment company (a “RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (“Code”). As a RIC, the Fund will not be subject to U.S. federal income tax on the portion of its net investment income and net capital gain that it distributes to shareholders, provided that it satisfies certain requirements of the Code. If the Fund does not qualify as a RIC for any taxable year and certain relief provisions are not available, the Fund’s taxable income will be subject to tax at the Fund level and to a further tax at the shareholder level when such income is distributed. To comply with the asset diversification test applicable to a RIC, the Fund will attempt to ensure that the value of swap contracts and options on shares of a single issuer does not exceed 25% of the Fund’s value at the close of any quarter. If the value of swap contracts and options on shares of a single issuer were to exceed 25% of the Fund’s total assets at the end of a tax quarter, the Fund, generally, has a grace period to cure such lack of compliance. If the Fund fails to timely cure, it may no longer be eligible to be treated as a RIC. Underlying Index Risk. Neither the Fund’s investment adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Index. The calculation and dissemination of the Index values may be delayed if the information technology or other facilities of the Index Provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.
