Fees and Expenses of the Fund The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund (“Fund Shares”). You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment) 0.0065 0.0000 0.0000 0.0065 “Other Expenses” are estimates based on the expenses the Fund expects to incur for the current fiscal year. Example This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell all of your Fund Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be: 68 224 Portfolio Turnover The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example, affect the Fund’s performance. Because the Fund has not yet commenced operations, portfolio turnover information is unavailable at this time. Principal Investment Strategies The Fund is an actively managed exchange-traded fund (“ETF”) that seeks to achieve its investment objective by investing in the equity securities of companies whose core technology involves generating, manipulating, detecting, or transmitting light for various technologies (“Photonic and Optical Companies”). “Photonics” refers to technologies that generate, detect, amplify, modulate, or process light at the device level — that is, technologies in which light is actively created, converted to or from electrical signals, or directly manipulated. “Optics” (or “optical” technologies) refers to technologies that direct or condition the propagation of light — including guiding, focusing, filtering, reflecting, splitting, or transmitting light — typically through components and systems such as lenses, mirrors, optical fiber, waveguides, and related connectivity infrastructure. Photonic technologies are generally active in that they create light or convert between optical and electrical signals, while optical technologies are generally passive in that they direct, condition, or transmit light generated elsewhere. Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities (which may include depositary receipts) or financial instruments (i.e., swap agreements or forward contracts) that provide exposure to Photonic and Optical Companies. For purposes of compliance with this investment policy, derivative contracts (i.e., swap agreements and forward contracts) will be valued at their notional value. The Fund’s adviser, Roundhill Financial Inc. (“Roundhill” or the “Adviser”), identifies for potential investment Photonic and Optical Companies with at least 50% of their revenues attributable to the research, development, manufacturing, or sale of one or more of the following optical and/or photonic technologies: <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Optical transceivers and modules, </td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Laser sources and photonic components, </td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Silicon photonics (“SiPh”) integrated circuits,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Optical interconnect systems,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Photonic substrates and wafer materials,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Photonic foundry and contract manufacturing services,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Industrial and defense lasers,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Precision photodetectors, sensors, and imaging systems,</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Fiber optic cable and connectivity infrastructure, </td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Optical computing and photonic AI acceleration, and</td></tr></table> <table cellpadding="0" cellspacing="0" style="font: 11pt Times New Roman, Times, Serif; width: 100%; margin-top: 0; margin-bottom: 0"><tr style="vertical-align: top"> <td style="width: 0.25in"></td><td style="width: 0.25in">●</td><td style="text-align: justify">Related technologies in photonics and/or optics.</td></tr></table> For additional information with respect to optical and photonic technologies in which the Fund may invest, please see the section entitled “Additional Information About the Fund’s Principal Investment Strategies”. In seeking to achieve the Fund’s investment objective, the Adviser constructs the portfolio using its proprietary security selection methodology. The Adviser generally invests in Photonic and Optical Companies it believes are leaders in optical and/or photonic products and related technologies, considering factors such as market share and revenue share derived from the sales or production of such products. The Fund will seek to invest in those companies with a minimum market capitalization of $1 billion and an average daily trading volume of at least $10 million. The Fund may invest in U.S. and non-U.S. companies (including those operating in developed or emerging market countries) through investments in depositary receipts, including American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) or depositary receipts whose underlying securities are non-voting preferred securities. As of the date of this prospectus, the Fund expects to invest significantly in the securities of Asian issuers. While the Photonic and Optical Companies in which the Fund will invest may be small-, mid- or large-capitalization issuers, many of such companies are relatively small and may have limited product lines, markets, financial resources, or personnel. The Fund rebalances and reconstitutes its portfolio at least quarterly using the Adviser’s proprietary weighting methodology that is a form of modified market cap weighting, allotting larger allocations to the largest incumbents in the Photonics and Optics space. The Fund does not actively trade securities between rebalances. ADRs are receipts issued by a depositary, usually a U.S. bank, and represent an ownership interest in an underlying security held by the depositary. The Fund may invest in sponsored and unsponsored ADRs. Sponsored ADRs are issued jointly by the issuer of the underlying security and the depositary, and can be listed on major U.S. exchanges. Unsponsored ADRs are issued by the depositary without the participation of the issuer of the underlying security, trade over-the-counter (“OTC”) and limit shareholder benefits and voting rights. Certain of the ADRs to which the Fund will have investment exposure may be structured as variable interest entities or “VIEs.” A VIE is a special structure designed to provide foreign investors with exposure to Chinese companies where direct foreign ownership is prohibited or limited. Investments in VIEs are made through an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company, then issues shares on a non-Chinese exchange, such as the New York Stock Exchange or the Hong Kong Stock Exchange to provide investors with exposure to the operating company but does not represent equity ownership in the operating company. As a result, such investments may limit the rights of an investor with respect to the underlying operating company. Investments in VIEs come with additional risks that are described in the section entitled “Principal Risks.” The Fund may also derive investment exposure to Chinese companies through investments in China A-Shares. China A-Shares represent equity securities of companies incorporated in mainland China, traded on the Shanghai and Shenzhen stock exchanges. Swap agreements are contracts entered into primarily with major financial institutions for a specified period ranging from a day to more than one year. In a “swap” transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on predetermined investments or instruments for a specified time period. The Fund enters into one or more OTC swap agreements with major global financial institutions for a specified period to provide exposure to Photonic and Optical Companies. The terms of the Fund’s OTC swap agreement are expected to provide payments whereby only the net amount is paid to the counterparty entitled to receive the net payment. The Fund’s obligations (or rights) under the OTC swap agreement will be equal only to the net amount to be paid or owed under the agreement, based on the relative values of the positions held by each counterparty. The swap has a similar economic effect as if the Fund were to invest in the assets underlying the swap in an amount equal to the notional amount of the swap. The return to the Fund on such swap should be the gain or loss on the notional amount plus dividends or interest on the assets less the interest paid by the Fund on the notional amount. However, unlike cash investments in the underlying assets, the Fund will not be an owner of the underlying assets and will not have voting or similar rights in respect of such assets. The Fund may hold cash, cash-like instruments or high-quality fixed income securities (collectively, a “Cash Position”). The Cash Position may be used to satisfy redemption requests, support the Fund’s use of unfunded total return swaps, manage liquidity, meet collateral or margin requirements, pay Fund expenses or pending investment in other instruments. The Cash Position may consist of income-producing (1) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury, including U.S. Treasury securities with remaining maturities of one year or less; (2) money market funds; (3) fixed income ETFs; (4) collateralized repurchase agreements; (5) investment-grade corporate debt securities, such as commercial paper and other short-term unsecured promissory notes; and/or (6) other eligible collateral instruments. The Fund will concentrate (i.e., invest more than 25% of its total assets) its investments in the group of industries comprising the information technology sector. The Fund is classified as “non-diversified” under the Investment Company Act of 1940 (the “1940 Act”). Fund Shares will change in value, and you could lose money by investing in the Fund. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. PHOTONIC AND OPTICAL COMPANIES RISK. Photonic and Optical Companies may be subject to rapid changes in technology, intense competition, government regulation, and obsolescence risk. Securities of such companies may be subject to greater price volatility than securities of companies in other sectors, particularly over the short term. The prices of securities of companies in these industries may fluctuate widely due to competitive pressures, rapid product cycles, changes in the regulatory environment, and shifts in supply and demand dynamics. Many Photonic and Optical Companies are relatively small and may have limited product lines, markets, financial resources, or personnel, making them more susceptible to business risks and adverse developments. Photonic and Optical Companies may also be dependent upon government contracts or subsidies, which may be subject to cancellation, renegotiation, or delay in payment. Additionally, the development and commercialization of photonic and optical technologies may be contingent upon the broader adoption of related technologies, including artificial intelligence, data center infrastructure, and advanced telecommunications networks. A slowdown or disruption in the growth of these related sectors could materially and adversely affect the revenues and profitability of Photonic and Optical Companies in which the Fund invests. MARKET RISK. Market risk is the risk that a particular investment, or Fund Shares in general, may fall in value. Securities are subject to market fluctuations caused by real or perceived adverse economic, political, and regulatory factors or market developments, changes in interest rates, disruptions to trade, impositions of tariffs and perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. In addition, local, regional or global events such as war, acts of terrorism, market manipulation, government defaults, government shutdowns, regulatory actions, political changes, diplomatic developments, the imposition of sanctions and other similar measures, spread of infectious diseases or other public health issues, recessions, natural disasters, or other events could have a significant negative impact on the Fund and its investments. Any of such circumstances could have a materially negative impact on the value of Fund Shares, the liquidity of an investment, and may result in increased market volatility. During any such events, Fund Shares may trade at increased premiums or discounts to their net asset value, the bid/ask spread on Fund Shares may widen and the returns on investment may fluctuate. LINE OF BUSINESS RISK. Certain companies included in the Fund’s portfolio will be engaged in other lines of business unrelated to the development of optical and/or photonic products, and these lines of business could adversely affect their operating results. The operating results of these companies may fluctuate as a result of these additional risks and events in the other lines of business. Despite a company’s possible success in activities linked to its development of optical and/or photonic products, there can be no assurance that the other lines of business in which these companies are engaged will not have an adverse effect on a company’s business or financial condition. EQUITY SECURITIES RISK. Equity securities are subject to changes in value, and their values may be more volatile than those of other asset classes. Equity securities prices fluctuate for several reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant equity market, such as market volatility, or when political or economic events affecting an issuer occur. Common stock prices may be particularly sensitive to rising interest rates, as the cost of capital rises and borrowing costs increase. Common stocks generally subject their holders to more risks than preferred stocks and debt securities because common stockholders’ claims are subordinated to those of holders of preferred stocks and debt securities upon the bankruptcy of the issuer. ACTIVE MANAGEMENT RISK. The Fund is actively-managed and its performance reflects investment decisions that the Adviser and/or Sub-Adviser makes for the Fund. Such judgments about the Fund’s investments may prove to be incorrect. If the investments selected and the strategies employed by the Fund fail to produce the intended results, the Fund could underperform as compared to other funds with similar investment objectives and/or strategies, or could have negative returns. ASIA RISK. The Fund invests significantly in the securities of Asian issuers. As such, the Fund is subject to certain risks specifically associated with investments in the securities of Asian issuers. Many Asian economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asian economies are highly dependent on trade, and economic conditions in other countries within and outside Asia can impact these economies. Certain of these economies may be adversely affected by trade or policy disputes with its major trade partners. There is also a high concentration of market capitalization and trading volume in a small number of issuers representing a limited number of industries, as well as a high concentration of investors and financial intermediaries. Certain Asian countries have experienced and may in the future experience expropriation and nationalization of assets, confiscatory taxation, currency manipulation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. In particular, escalated tensions involving North Korea and any outbreak of hostilities involving North Korea could have a severe adverse effect on Asian economies. Governments of certain Asian countries have exercised, and continue to exercise, substantial influence over many aspects of the private sector. In certain cases, the government owns or controls many companies, including the largest in the country. Accordingly, government actions could have a significant effect on the issuers of the Fund’s securities or on economic conditions generally. Recent developments in relations between the U.S. and China have heightened concerns of increased tariffs and restrictions on trade between the two countries. An increase in tariffs or trade restrictions, or even the threat of such developments, could lead to a significant reduction in international trade, which could have a negative impact on the economy of Asian countries and a commensurately negative impact on the Fund. China Risk. The Fund may invest in instruments that provide exposure to Chinese companies, including through investments in China A-Shares, which would subject the Fund to risks specific to China. China may be subject to considerable degrees of economic, political and social instability. China is an emerging market and demonstrates significantly higher volatility from time to time in comparison to developed markets. Over the last few decades, the Chinese government has undertaken reform of economic and market practices and has expanded the sphere of private ownership of property in China. However, Chinese markets generally continue to experience inefficiency, volatility and pricing anomalies resulting from governmental influence, a lack of publicly available information and/or political and social instability. Chinese companies are also subject to the risk that Chinese authorities can intervene in their operations and structure. Internal social unrest or confrontations with neighboring countries, including military conflicts in response to such events, may also disrupt economic development in China and result in a greater risk of currency fluctuations, currency non-convertibility, interest rate fluctuations and higher rates of inflation. China has experienced security concerns, such as terrorism and strained international relations. Additionally, China is alleged to have participated in state-sponsored cyberattacks against foreign companies and foreign governments. Actual and threatened responses to such activity and strained international relations, including purchasing restrictions, sanctions, tariffs or cyberattacks on the Chinese government or Chinese companies, may impact China’s economy and Chinese issuers of securities in which the Fund invests. Incidents involving China’s or the region’s security may cause uncertainty in Chinese markets and may adversely affect the Chinese economy and the Fund’s investments. Export growth continues to be a major driver of China’s rapid economic growth. Reduction in spending on Chinese products and services, supply chain diversification, institution of additional tariffs or other trade barriers (including as a result of heightened trade tensions or a trade war between China and the U.S. or in response to actual or alleged Chinese cyber activity) or a downturn in any of the economies of China’s key trading partners may have an adverse impact on the Chinese economy. The Fund’s portfolio may include companies that are subject to economic or trade restrictions (but not investment restrictions) imposed by the U.S. or other governments due to national security, human rights or other concerns of such government. So long as these restrictions do not include restrictions on investments, the Fund is generally expected to invest in such companies. Chinese companies are not subject to the same degree of regulatory requirements, accounting standards or auditor oversight as companies in more developed countries. As a result, information about the Chinese securities in which the Fund invests may be less reliable or complete. Chinese companies with securities listed on U.S. exchanges may be delisted if they do not meet U.S. accounting standards and auditor oversight requirements, which would significantly decrease the liquidity and value of the securities. There may be significant obstacles to obtaining information necessary for investigations into or litigation against Chinese companies, and shareholders may have limited legal remedies. Chinese companies may also be subject to significantly weaker recordkeeping requirements than the requirements imposed upon U.S. companies. China A-Shares Risk. China A-Shares are equity securities issued by companies incorporated in mainland China and listed for trading on Chinese stock exchanges. Foreign investors may obtain exposure to China A-Shares by securing a Qualified Foreign Institutional Investor or Renminbi Qualified Foreign Institutional Investor license, or by investing through the Stock Connect Program, a securities trading and clearing arrangement designed to provide reciprocal stock market access between mainland China and Hong Kong. The China A-Share markets are generally viewed as emerging markets and may exhibit lower trading volumes and reduced liquidity. A-Share investments are also subject to regulatory regimes and investment limits, and the ability to recover or repatriate assets invested in A-Shares may be constrained by restrictions imposed by the Chinese government. In addition, investors outside mainland China may encounter limitations or prohibitions on access to certain A-Shares, including securities that may appear on restricted lists in jurisdictions such as the United States. A-Shares may further be subject to frequent and broad-based trading halts, which can contribute to price volatility and reduced liquidity. Trading suspensions in particular securities may increase the Fund’s execution, clearing, and settlement risks and costs, and may also disrupt the creation and redemption of Creation Units. These and other risks could adversely affect the value of the Fund’s investments. ASSET CLASS RISK. Securities and other assets in the Fund’s portfolio may underperform in comparison to the general financial markets, a particular financial market or other asset classes. CONCENTRATION RISK. The Fund is concentrated in the industry or group of industries comprising the information technology sector. The Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the Fund’s investments more than the market as a whole, to the extent that the Fund’s investments are concentrated in the securities and/or other assets of a particular issuer or issuers, country, group of countries, region, market, industry, group of industries, sector, market segment or asset class. CURRENT MARKET CONDITIONS RISK. Current market conditions risk is the risk that a particular investment, or Fund Shares in general, may fall in value due to current market conditions. As a means to fight inflation, which remains at elevated levels, the Federal Reserve and certain foreign central banks have raised interest rates; however, the Federal Reserve has recently lowered interest rates and may continue to do so. U.S. regulators have proposed several changes to market and issuer regulations which would directly impact the Fund, and any regulatory changes could adversely impact the Fund’s ability to achieve its investment strategies or make certain investments. Recent and potential future bank failures could result in disruption to the broader banking industry or markets generally and reduce confidence in financial institutions and the economy as a whole, which may also heighten market volatility and reduce liquidity. Additionally, challenges in commercial real estate markets, including rising interest rates, declining valuations and increasing vacancies, could have a broader impact on financial markets. The ongoing adversarial political climate in the United States, as well as political and diplomatic events both domestic and abroad, have and may continue to have an adverse impact on the U.S. regulatory landscape, markets and investor behavior, which could have a negative impact on the Fund’s investments and operations. The change in administration resulting from the 2024 United States national elections could result in significant impacts to international trade relations, tax and immigration policies, and other aspects of the national and international political and financial landscape, which could affect, among other things, inflation and the securities markets generally. Other unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy. For example, ongoing armed conflicts between Russia and Ukraine in Europe and among Israel, Iran, Hamas and other militant groups in the Middle East, have caused and could continue to cause significant market disruptions and volatility within the markets in Russia, Europe, the Middle East and the United States. The hostilities and sanctions resulting from those hostilities have and could continue to have a significant impact on certain Fund investments as well as Fund performance and liquidity. The economies of the United States and its trading partners, as well as the financial markets generally, may be adversely impacted by trade disputes, including the imposition of tariffs, and other matters. For example, the United States has imposed trade barriers and restrictions on China. In addition, the Chinese government is engaged in a longstanding dispute with Taiwan, continually threatening an invasion. If the political climate between the United States and China does not improve or continues to deteriorate, if China were to attempt invading Taiwan, or if other geopolitical conflicts develop or worsen, economies, markets and individual securities may be adversely affected, and the value of the Fund’s assets may go down. A public health crisis and the ensuing policies enacted by governments and central banks may cause significant volatility and uncertainty in global financial markets, negatively impacting global growth prospects. As the COVID-19 global pandemic illustrated, such events may affect certain geographic regions, countries, sectors and industries more significantly than others. Advancements in technology may also adversely impact markets and the overall performance of the Fund. For instance, the economy may be significantly impacted by the advanced development and increased regulation of artificial intelligence. Additionally, cyber security breaches of both government and non-government entities could have negative impacts on infrastructure and the ability of such entities, including the Fund, to operate properly. These events, and any other future events, may adversely affect the prices and liquidity of the Fund’s portfolio investments and could result in disruptions in the trading markets. CYBERSECURITY RISK. Failures or breaches of the electronic systems of the Fund, the Fund’s adviser, sub-adviser, distributor, and other service providers, market makers, Authorized Participants or the issuers of securities in which the Fund invests have the ability to cause disruptions, negatively impact the Fund’s business operations and/or potentially result in financial losses to the Fund and its shareholders. While the Fund has established business continuity plans and risk management systems seeking to address system breaches or failures, there are inherent limitations in such plans and systems. Furthermore, the Fund cannot control the cybersecurity plans and systems of the Fund’s other service providers, market makers, Authorized Participants or issuers of securities in which the Fund invests. DEPOSITARY RECEIPTS RISK. Depositary receipts may be less liquid than the underlying shares in their primary trading market. Any distributions paid to the holders of depositary receipts are usually subject to a fee charged by the depositary. Holders of depositary receipts may have limited voting rights, and investment restrictions in certain countries may adversely impact the value of depositary receipts because such restrictions may limit the ability to convert the equity shares into depositary receipts and vice versa. Such restrictions may cause the equity shares of the underlying issuer to trade at a discount or premium to the market price of the depositary receipts. The issuers of unsponsored ADRs are not obligated to disclose information that is considered material in the U.S. and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the ADRs. Additionally, unsponsored ADRs limit shareholder benefits and voting rights. DERIVATIVES RISK. The use of derivative instruments (i.e., swap agreements and forward contracts) involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include: (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Trading derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities. Derivative contracts ordinarily have leverage inherent in their terms. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet regulatory or contractual requirements for derivatives. The use of derivatives can magnify potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund Share price. EMERGING MARKETS RISK. The Fund’s investments in emerging markets may be subject to a greater risk of loss than investments in more developed markets. Emerging markets may be more likely to experience inflation, political turmoil and rapid changes in economic conditions than more developed markets. Emerging markets often have less uniformity in accounting and reporting requirements, unreliable securities valuation and greater risk associated with custody of securities. FORWARD CONTRACTS RISK. The Fund may utilize forward contracts to derive its exposure to Photonic and Optical Companies. A forward contract is an over-the-counter derivative transaction between two parties to buy or sell a specified amount of an underlying reference at a specified price (or rate) on a specified date in the future. Forward contracts are negotiated on an individual basis and are not standardized or traded on exchanges. The market for forward contracts is substantially unregulated and can experience lengthy periods of illiquidity, unusually high trading volume and other negative impacts, such as political intervention, which may result in volatility or disruptions in such markets. A relatively small price movement in a forward contract may result in substantial losses to the Fund, exceeding the amount of the margin paid. INFORMATION TECHNOLOGY COMPANIES RISK. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Like other technology companies, information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face obsolescence due to rapid technological developments, frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Companies in the information technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. Information technology companies are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action. INTERNATIONAL CLOSED MARKET TRADING RISK. To the extent securities held by the Fund trade on non-U.S. 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 last quoted price for the underlying security (i.e., the Fund’s quote from the closed foreign market) used for purposes of calculating the Fund’s NAV, resulting in premiums or discounts to the Fund’s NAV and bid/ask spreads that may be greater than those experienced by other funds. In addition, shareholders may not be able to purchase and sell shares of the Fund on days when the NAV of the Fund could be significantly affected by events in the relevant foreign markets (e.g., market holidays, market trading halts or significant volatility in foreign markets). ISSUER RISK. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Changes in the financial condition or credit rating of an issuer of those securities may cause the value of the securities to decline. There is no guarantee that an issuer that paid dividends in the past will continue to do so in the future or will continue paying dividends at the same level. LARGE-CAPITALIZATION COMPANIES RISK. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Large capitalization companies may be more mature and subject to more limited growth potential compared with smaller capitalization companies. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets. MID-CAPITALIZATION COMPANIES RISK. Mid-capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than larger, more established companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than larger, more established companies. NEW FUND RISK. The Fund is a recently organized 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. As a “non-diversified” fund, the Fund may hold a smaller number of portfolio securities than many other funds. To the extent the Fund invests in a relatively small number of issuers, a decline in the market value of a particular security held by the Fund may affect its value more than if it invested in a larger number of issuers. The value of the Fund Shares may be more volatile than the values of shares of more diversified funds. NON-U.S. SECURITIES RISK. Non-U.S. securities are subject to higher volatility than securities of domestic issuers due to possible adverse political, social or economic developments, restrictions on foreign investment or exchange of securities, capital controls, lack of liquidity, currency exchange rates, excessive taxation, government seizure of assets, the imposition of sanctions by foreign governments, different legal or accounting standards, and less government supervision and regulation of securities exchanges in foreign countries. 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 the Adviser seek to reduce these operational risks through controls and procedures, there is no way to completely protect against such risks. PREFERRED SECURITIES RISK. The Fund may invest significantly in depositary receipts whose underlying securities are non-voting preferred securities. Preferred securities combine some of the characteristics of both common stocks and bonds. Preferred securities are typically subordinated to bonds and other debt securities in a company’s capital structure in terms of priority to corporate income, subjecting them to greater credit risk than those debt securities. Generally, holders of preferred securities have no voting rights with respect to the issuing company unless preferred dividends have been in arrears for a specified number of periods, at which time the preferred security holders may obtain limited rights. In certain circumstances, an issuer of preferred securities may defer payment on the securities and, in some cases, redeem the securities prior to a specified date. Preferred securities may also be substantially less liquid than other securities, including common stock. SMALL-CAPITALIZATION COMPANIES RISK. Small-capitalization companies may be more vulnerable to adverse general market or economic developments, and their securities may be less liquid and may experience greater price volatility than large- and mid-capitalization companies as a result of several factors, including limited trading volumes, fewer products or financial resources, management inexperience and less publicly available information. Accordingly, such companies are generally subject to greater market risk than large- and mid-capitalization companies. STRUCTURAL ETF RISKS. The Fund is an ETF. Accordingly, it is subject to certain risks associated with its unique structure. Cash Transactions Risk. The Fund may effect a portion of its creations and redemptions for cash, rather than in-kind securities. Paying redemption proceeds in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio securities or other assets at an inopportune time to obtain the cash needed to meet redemption orders. This may cause the Fund to sell a security and recognize a capital gain or loss that might not have been incurred if it had made a redemption in-kind. As a result, the Fund may pay out higher or lower annual capital gains distributions than ETFs that redeem in-kind. The use of cash creations and redemptions may also cause the Fund Shares to trade in the market at greater bid-ask spreads or greater premiums or discounts to the Fund’s NAV. Furthermore, the Fund may not be able to execute cash transactions for creation and redemption purposes at the same price used to determine the Fund’s NAV. To the extent that the maximum additional charge for creation or redemption transactions is insufficient to cover the execution shortfall, the Fund’s performance could be negatively impacted. Active Market Risk. Although Fund Shares are listed for trading on the Exchange, there can be no assurance that an active trading market for Fund Shares will develop or be maintained. Fund Shares trade on the Exchange at market prices that may be below, at or above the Fund’s net asset value. Securities, including Fund Shares, are subject to market fluctuations and liquidity constraints that may be caused by such factors as economic, political, or regulatory developments, changes in interest rates, and/or perceived trends in securities prices. Fund Shares could decline in value or underperform other investments. Market Participants Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and none of those Authorized Participants is obligated to engage in creation and/or redemption transactions. The Fund has a limited number of institutions that may act as Authorized Participants on an agency basis (i.e., on behalf of other market participants). To the extent that Authorized Participants exit the business or are unable to proceed with creation or redemption orders with respect to the Fund and no other Authorized Participant is able to step forward to create or redeem, Fund Shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting. The Fund may also rely on a small number of third-party market makers to provide a market for the purchase and sale of Fund Shares but such market makers are under no obligation to do so. Decisions by Authorized Participants or market makers 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. Any trading halt or other problem relating to the trading activity of these market makers or any issues disrupting the Authorized Participants’ ability to proceed with creation and/or redemption orders could result in a dramatic change in the spread between the Fund’s net asset value and the price at which Fund Shares are trading on the Exchange, which could result in a decrease in value of Fund Shares. This reduced effectiveness could result in Fund Shares trading at a premium or discount to net asset value and also in greater than normal intraday bid-ask spreads for Fund Shares. Costs of Buying and Selling Fund Shares. Due to the costs of buying or selling Fund Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Fund Shares may significantly reduce investment results and an investment in Fund Shares may not be advisable for investors who anticipate regularly making small investments. Premium/Discount Risk. As with all ETFs, Fund Shares may be bought and sold in the secondary market at market prices. The trading prices of Fund Shares in the secondary market may differ from the Fund’s daily net asset value per share and there may be times when the market price of the shares is more than the net asset value per share (premium) or less than the net asset value per share (discount). If a shareholder purchases Fund Shares at a time when the market price is at a premium to the net asset value or sells Fund Shares at a time when the market price is at a discount to the net asset value, the shareholder may pay more for, or receive less than, the underlying value of the Fund Shares, respectively. This risk is heightened in times of market volatility or periods of steep market declines. Trading Risks. Although Fund Shares are listed for trading on the Exchange and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Fund Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Fund Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Fund Shares. Trading in Fund Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund Shares inadvisable. In addition, trading in Fund Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange’s “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged. SWAP AGREEMENTS RISK. The Fund may utilize swap agreements to derive its exposure to Photonic and Optical Companies. Swap agreements may involve greater risks than direct investment in securities as they may be leveraged and are subject to credit risk, counterparty risk and valuation risk. A swap agreement could result in losses if the underlying reference or asset does not perform as anticipated. In addition, many swaps trade over-the-counter and may be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses. VARIABLE INTEREST ENTITY RISK. Exposure to VIEs may pose additional risks because the investment is made in reference to an intermediary shell company that has entered into service and other contracts with the underlying Chinese operating company to provide investors with exposure to the operating company, but does not represent equity ownership in the operating company. As a result, such investment may limit the rights of an investor with respect to the underlying Chinese operating company. VIEs allow foreign shareholders to exert a degree of control over, and obtain economic benefits arising from, the operating company without formal legal ownership. However, the contractual arrangements between the shell company and the operating company may not be as effective in providing operational control as direct equity ownership, and a foreign investor's rights may be limited by, for example, actions of the Chinese government which could determine that the underlying contractual arrangements on which control of the VIE is based are invalid. The contractual arrangement on which the VIE structure is based would likely be subject to Chinese law and jurisdiction, which could raise questions about how recourse is sought. Investments through VIEs may be affected by conflicts of interest and duties between the legal owners of the VIE and the stockholders of the listed holding company, which could adversely impact the value of investments. VIEs are not formally recognized under Chinese law and investors face uncertainty about future actions by the Chinese government that could significantly affect the operating company's financial performance and the enforceability of the contractual arrangements underlying the VIE structure. Prohibitions of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant losses, and in turn, adversely affect the Fund's returns and net asset value.
