TABLE OF CONTENTS

FUND SUMMARY - TCW Transform Supply Chain ETF (formerly, Engine No. 1 Transform Supply Chain ETF) (the “Fund”)

Principal Investment Strategies:

Principal Investment Risks:

Investment Adviser: Effective October 13, 2023, TCW Investment Management Company LLC (“TCW” or the “Adviser”) replaced Fund Management at Engine No. 1 LLC (“Fund Management”) as the investment adviser to the Fund pursuant to the acquisition by TCW Group Inc., TCW’s parent company, of Fund Management’s business of operating, sponsoring and advising the Trust (the “ETF Business”), including through the acquisition of the assets that were primarily used or held by Fund Management in the conduct of the ETF Business and through the assumption of certain liabilities related to, arising from or in respect of the ETF Business.

Portfolio Managers: Eli Horton and Molly Landes are jointly and primarily responsible for the day-to-day management of the Fund. Ms. Landes and Mr. Horton have each been portfolio managers of the Fund since its inception. Mr. Horton is a Managing Director and Senior Portfolio Manager at the Adviser. Ms. Landes is a Senior Vice President and ETF Portfolio Manager/Capital Markets Lead at the Adviser.

Purchase and Sale of Fund Shares: The Fund is an ETF and as such will issue and redeem shares at NAV only in large blocks of shares (each block of shares is called a “Creation Unit”). Creation Units are issued and redeemed for cash and/or in-kind for securities. Individual shares of the Fund may only be bought and sold in the secondary market through a broker-dealer. Because ETF shares trade at market prices rather than at NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount). An investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the “bid-ask spread”).

Tax Information: The Fund’s distributions generally will be taxable as ordinary income or long-term capital gains. A sale of shares may result in capital gain or loss.

Payments to Broker-Dealers and Other Financial Intermediaries: If you purchase shares of the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay certain intermediaries for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.

More Information About the Fund

This Prospectus contains important information about investing in the Fund. Please read this Prospectus carefully before you make any investment decisions. Additional information regarding the Fund, including information on the Fund’s net asset value, market price, premiums and discounts and bid-ask spreads, can be found at https://tcw.com.

TCW is the investment adviser to the Fund. Shares of the Fund are listed for trading on Cboe BZX Exchange, Inc. (“Cboe”). The market price for a share of the Fund may be different from the Fund’s most recent NAV.

ETFs are funds that trade like other publicly-traded securities. Similar to shares of a mutual fund, each share of the Fund represents an ownership interest in an underlying portfolio of securities and other instruments. Unlike shares of a mutual fund, which can be bought and redeemed from the issuing fund by all shareholders at a price based on NAV, shares of the Fund may be purchased or redeemed directly from the Fund at NAV solely by Authorized Participants and only in aggregations of a specified number of shares (“Creation Units”). Also unlike shares of a mutual fund, shares of the Fund are listed on a national securities exchange and trade in the secondary market at market prices that change throughout the day.

The Fund invests in a particular segment of the securities markets (i.e., common equity securities). It is designed to be used as part of broader asset allocation strategies. Accordingly, an investment in the Fund should not constitute a complete investment program.

An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency, the Adviser or any of its affiliates.

The Fund’s investment objective may be changed without shareholder approval.

ADDITIONAL INFORMATION ABOUT PRINCIPAL INVESTMENT STRATEGIES AND RELATED RISKS

Investment Objective:

The Fund’s investment objective is long-term growth of capital. The Fund’s investment objective may be changed by the Board of Trustees without shareholder approval.

The Fund has adopted a non-fundamental policy not to purchase securities of other investment companies, except to the extent permitted by the 1940 Act and the rules thereunder.

Principal Investment Strategies:

The Transform Supply Chain ETF is an actively managed exchange-traded fund (“ETF”) that invests in U.S.-listed equity, American depositary receipt (“ADR”) securities, and non-U.S. developed and emerging market-listed securities, which over time may vary as market and investment opportunities change. The Fund may also enter into currency-related spot transactions when it transacts in equities denominated in foreign currencies or invest in certain derivative instruments, such as currency futures or forwards that will help the Adviser manage risk associated with foreign currency exposure, if any, or futures contracts. The Fund’s investments may include micro-, small-, medium- and large-capitalization equities of companies. The Adviser expects to hold between 20-40 equities within the Fund’s portfolio.

The Adviser expects to invest in the equities of companies that it deems are creating value through supply chain transformation. A supply chain is defined as a network between a company and its suppliers to produce and distribute a specific product to the final buyer. According to the Adviser, companies are transforming their own or others’ supply chains by reshoring manufacturing jobs (i.e., bringing jobs closer to point of sale, stabilizing manufacturing capacity, reducing disruption and geopolitical risks, enhancing sourcing transparency and increasing emissions and environmental impact standards), automating and/or innovating business operations (i.e., offsetting labor cost disadvantage of high-cost countries by boosting output per worker, streamlining business operations to drive lower costs, and improving labor conditions for workers), or through transportation enablement (i.e., providing manufacturers with reliable and affordable access to raw materials, while also facilitating movement of finished goods to end market). Portfolio companies are primarily those that the Adviser believes are creating value or minimizing risks as it relates to their supply chains or the supply chains of others. Companies are from no one particular industry; instead, they are from a broad range of industries such as factory automation, transportation providers, industrial goods and services, alternative energy, semiconductors and semiconductor capital equipment, materials, or waste management & recycling.

Companies are typically chosen from the Morningstar^® US Market Extended TR USD Index℠ but may be selected from a universe of U.S. and non-U.S. listed equity securities that span across sectors, including but not limited to consumer discretionary, industrials, materials, and technology. The Morningstar^® US Market Extended TR USD Index℠ is a broad-based free-float market capitalization weighted index comprised of U.S. large, mid, and small capitalization equity securities that span all sectors of the U.S. economy. It does not incorporate environmental, social and governance criteria into its methodology, nor is it an index comprised of equities of companies that could be considered as aiding the supply chain.

When selecting equities of companies for the portfolio, the Adviser will assess a company’s strategy and financial performance by doing things such as attending company earnings calls, interviewing management, visiting company headquarters and manufacturing plants, reviewing company reports such as Form 10-K’s, financial statements (i.e., balance sheet, income statement, and statement of cash flows), publicly available and sell-side research and performing fundamental financial analyses such as company financial modeling and ratio analysis. For example, the Fund may invest in the equities of companies that have better long-term financial stability and profitability relative to peers (using metrics such as net sales revenue, EBITDA (earnings before interest, taxes, depreciation and amortization), profit margin, or market share) as a result of their supply chain strategy. The Adviser also expects to include, as part of its company assessments, additional company reporting, targets, progress, and strategic positioning, such as:

Companies whose leadership has made it a strategic business focus, made changes to its business operations, or made commitments that address sustainability factors specific to supply chain instability & insecurity such as:

Such companies will be identified and assessed through reporting on targets and progress through various sources, such as regulatory filings, annual reports, or shareholder meetings, related to:

The Adviser considers environmental and governance risk factors as part of its investment process, particularly in considering the ways in which each company’s externalities, and the management of these factors, could ultimately drive financial performance. The Adviser does not use aggregated environmental or governance ratings or rankings to exclude specific companies or sectors from investment, but instead generally uses its own proprietary analysis of each company’s specific externalities to make better informed decisions. The Adviser generally estimates these externalities using data from the companies themselves, and publicly available data sources (e.g., Bloomberg, Economic Policy Institute, Environmental Protection Agency (EPA), International Council on Clean Transportation (ICCT), Federal Reserve Economic Data, MIT Living Wage Calculator, US Department of Agriculture (USDA), U.S. Bureau of Labor Statistics, U.S. Department of Transportation, U.S. Energy Information Administration).

The Adviser may utilize a quantitative and/or a qualitative approach to measuring the effects of company supply chains, based on both public information as well as a due diligence process (noted above) undertaken by the Adviser with respect to potential investments that focuses on key impacts on supply chains, including greater supply chain stability and security, job creation and lower environmental impact.

As part of its due diligence process for prospective and ongoing investments, the Adviser then assesses the ways those decisions may affect company revenue and earnings projections, discount rates, terminal values (i.e., the calculated rate at which it is assumed its cash flows will grow at forever), and valuations particularly through changes in regulation; customer or employee preferences; and competitive risk from innovation or disruption. For example, the Adviser may use one or multiple data sources to estimate supply chain stability and security, job creation and lower environmental impact, associated with a company’s products and services and then assess how possible changes in trade policy, regulations within various industries are shifting demand for certain products and services based on consumer preferences. The Adviser may then estimate the risk of disruption from more innovative or more cost effectively produced products and services created by competitors, including how such developments could potentially lower long-term growth assumptions, increase the discount rates the Adviser applies to that growth to account for higher risk, reduce terminal values to reflect lower terminal growth, and as a result lower assumed valuation of the company.

These criteria by which the Adviser assesses companies for investment by the Fund will be applied to all investments by the Fund except for temporary investments or investments in cash equivalents.

In furtherance of its investment objective and where the Adviser believes it will be rewarded in the stock price, the Fund seeks to encourage accountability, change acceleration or transformational change at the public companies within its portfolio specifically through the application of proxy voting guidelines and through dialogue with management of the portfolio companies. The proxy voting guidelines are based on a commitment to protecting and enhancing the value of the Fund’s assets and driving increased transparency and accountability to align shareholder and stakeholder interests through favoring actions that encourage companies to create long-term value. Generally, in applying the proxy voting guidelines and in seeking to engage in dialogue with companies within the Fund’s portfolio, the Adviser may measure the investment made by companies in their employees, communities, customers, and the environment using financial, operational, and environmental and/or governance data provided by (i) the companies themselves, (ii) several publicly available data sources and (iii) the Adviser itself. This data may include, but are not limited to, air pollution, board composition, carbon emissions, employee health and safety, land use, wages, workforce diversity, among others. The Adviser will collect qualitative and quantitative data and compare the data against benchmarks based on industry trends. The Fund’s proxy voting guidelines, as well as the financial, operational and environmental and governance data included in such guidelines, will apply to all companies held by the Fund.

The Fund may lend securities representing up to one-third of the value of the Fund’s total assets (including the value of any collateral received), however it is a priority of the Adviser and the Fund to vote all proxies, so securities lending revenue may be foregone as a result. The Fund is a “non-diversified” fund, and, as such, may invest a greater percentage of its assets in the securities of a single issuer than funds that are “diversified.”

Principal Investment Risks

As with any investment, you could lose all or part of your investment in the Fund, and the Fund’s performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund’s NAV per share, trading price, yield, total return and ability to meet its investment objective. The order of the below risk factors does not indicate the significance of any particular risk factor.

ETF Structure Risks. The Fund is structured as an ETF and is subject to the special risks, including:

Not Individually Redeemable. Shares are not individually redeemable to retail investors and may be redeemed by the Fund only to Authorized Participants at NAV in large blocks known as “Creation Units.” An Authorized Participant may incur brokerage costs purchasing enough shares to constitute a Creation Unit.

Trading Issues. An active trading market for the Fund’s shares may not be developed or maintained. Trading in shares on the Cboe may be halted due to market conditions or for reasons that, in the view of the Cboe, make trading in shares inadvisable, such as extraordinary market volatility. There can be no assurance that shares will continue to meet the listing requirements of the Cboe. If the Fund’s shares are traded outside a collateralized settlement system, the number of financial institutions that can act as Authorized Participants that can post collateral on an agency basis is limited, which may limit the market for the Fund’s shares. 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) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants 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.

Market Trading Risk. The Fund faces numerous market trading risks, including the potential lack of an active market for Fund shares, losses from trading in secondary markets, periods of high volatility and disruptions in the creation/redemption process. The market price of the Fund’s shares also will include a “bid-ask spread” charged by the exchange specialists, market makers or other participants that trade the particular security. Any of these factors, among others, may lead to the Fund’s shares trading at a premium or discount to NAV. There may be times when the market price and the NAV vary significantly.

Secondary market trading in Fund shares may be halted by a stock exchange because of market conditions or for other reasons. In addition, trading in Fund shares on a stock exchange or in any market may be subject to trading halts caused by extraordinary market volatility pursuant to “circuit breaker” rules on the stock exchange or market.

Shares of the Fund, similar to shares of other issuers listed on a stock exchange, may be sold short and are therefore subject to the risk of increased volatility and price decreases associated with being sold short. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to the deteriorating liquidity of the Fund’s portfolio. This adverse effect on the liquidity of the Fund’s shares may, in turn, lead to differences between the market value of the Fund’s shares and the Fund’s NAV.

Fluctuation of Net Asset Value Risk. The NAV of the Fund’s shares will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of and demand for the Fund’s shares on the Cboe. The Adviser cannot predict whether the shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for the Fund’s shares will be closely related to, but not identical to, the same forces influencing the prices of the Fund’s holdings trading individually or in the aggregate at any point in time.

Authorized Participant Concentration 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 Creation Units, Fund shares may be more likely to trade at a premium or discount to NAV and possibly face trading halts or delisting.

Supply Chain Risks. Companies supply chains are generally subject to risk such as legislative or regulatory changes; adverse market conditions and/or increased competition; technological developments and changing technology; cyberattacks that may compromise a company’s operations or business; occasional sharp price movements which may result from changes in the economy, fuel prices, labor agreements, exchange rate movements, and insurance costs; pandemics, natural disasters or other crisis; boarder and/or import controls; pent-up /increased demand; mobility restrictions; shortages of product and labor; dependence on intellectual property rights, and potential loss or impairment of those rights; research and development costs; and rapid product obsolescence. Global, regional, or local events, such as changes to trade relations, trade restrictions, and/or military conflict, may materially disrupt or indefinitely impair the operations of these companies. Securities of these companies may be cyclical and occasionally subject to sharp price movements. Certain companies may be subject to significant regulation, including environmental regulation, by federal, state and local governmental agencies.

Active Ownership Risk. Active ownership can take any of several forms, including proxy battles, publicity campaigns, and negotiations with management. In the event that an affiliate of the Fund or its investment adviser is engaged in an activist campaign with respect to a portfolio company, the Fund may be foreclosed from taking certain actions with respect to that company as a result of prohibitions on engaging in joint transactions with affiliates under Section 17(d) of the 1940 Act or as a result of other regulatory or fiduciary concerns. In addition, while the Fund intends to seek select opportunities to actively engage with one or more portfolio companies, it may only be able to do so in limited circumstances where no other affiliated fund has elected to do so with respect to the same portfolio companies. The Fund intends to be focused and directed in the selection of opportunities to actively engage with its portfolio companies. However, the foregoing restrictions and priorities may limit the Fund’s ability to engage with some of those select opportunities. In addition, the Fund may also be deemed to have knowledge of material nonpublic information with respect to portfolio companies from time to time as a result of actions being contemplated by one or more of its affiliates, which may limit its ability to trade in a specific name or buy or sell a position even if it may otherwise be appropriate to do so. In the event the Fund were to engage in activism, such activities may not be successful, or even if successful, the Fund’s investment may lose value. These limitations may reduce the ability of the Fund to fulfill its active ownership strategy.

Limited History of Operations Risk. The Fund is a new fund with limited history of operations for investors to evaluate.

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

Equity Securities Risk. The Fund invests in equity securities, which are subject to changes in value that may be attributable to market perception of a particular issuer or to general stock market fluctuations that affect all issuers. Investments in equity securities may be more volatile than investments in other asset classes.

Active Management Risk. The Fund is actively managed, which means that investment decisions are made based on the Adviser’s investment views. There is no guarantee that the investment views will produce the desired results or expected returns, which may cause the Fund to fail to meet its investment objective or to underperform its benchmark index or funds with similar investment objectives and strategies. Furthermore, active trading that can accompany active management may result in high portfolio turnover, which may have a negative impact on performance. Active trading may result in higher brokerage costs or mark-up charges, which are ultimately passed on to shareholders of the Fund. Active trading may also result in adverse tax consequences.

Small and Medium Capitalization Companies Risk. The earnings and prospects of small and medium sized companies are more volatile than larger companies and may experience higher failure rates than larger companies. Small and medium sized companies normally have a lower trading volume than larger companies, which may tend to make their market prices fall more disproportionately than larger companies in response to selling pressures. In addition, small and medium sized companies may have limited markets, product lines, or financial resources and lack management experience.

American Depositary Receipt (“ADR”) Risk. ADRs are receipts issued by US banks evidencing ownership in securities of foreign issuers. Securities of foreign issuers, and consequently ADRs, may decrease in value due to changes in currency exchange rates, the economic climate in the issuer’s home country or for a variety of other reasons.

Asset Class Risk. The securities and other assets in the Fund’s portfolio may underperform in comparison to other securities or indexes that track other countries, groups of countries, regions, industries, groups of industries, markets, asset classes or sectors. Various types of securities, currencies and indexes may experience cycles of outperformance and underperformance in comparison to the general financial markets depending upon a number of factors including, among other things, inflation, interest rates, productivity, global demand for local products or resources, and regulation and governmental controls. This may cause the Fund to underperform other investment vehicles that invest in different asset classes.

Cybersecurity Risk. With the increased use of technologies such as the internet to conduct business, the Fund, Authorized Participants, service providers and the relevant listing exchange are susceptible to operational, information security and related “cyber” risks both directly and through their service providers. Similar types of cybersecurity risks are also present for issuers of securities in which the Fund invests, which could result in material adverse consequences for such issuers and may cause the Fund’s investment in such portfolio companies to lose value. Unlike many other types of risks faced by the Fund, these risks typically are not covered by insurance. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber incidents include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyberattacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Recently, geopolitical tensions may have increased the scale and sophistication of deliberate attacks, particularly those from nation-states or from entities with nation-state backing.

Cybersecurity failures by or breaches of the systems of the Fund’s adviser, distributor and other service providers (including, but not limited to, index and benchmark providers, fund accountants, custodians, transfer agents and administrators), market makers, Authorized Participants or the issuers of securities in which the Fund invests, have the ability to cause disruptions and impact business operations, potentially resulting in: financial losses, interference with the Fund’s ability to calculate its NAV, disclosure of confidential trading information, impediments to trading, submission of erroneous trades or erroneous creation or redemption orders, the inability of the Fund or its service providers to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, cyberattacks may render records of Fund assets and transactions, shareholder ownership of Fund shares, and other data integral to the functioning of the Fund inaccessible or inaccurate or incomplete. Substantial costs may be incurred by the Fund in order to resolve or prevent cyber incidents in the future. While the Fund has established business continuity plans in the event of, and risk management systems to prevent, such cyber incidents, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified and that prevention and remediation efforts will not be successful or that cyberattacks will go undetected. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by service providers to the Fund, issuers in which the Fund invests, market makers or Authorized Participants. The Fund and its shareholders could be negatively impacted as a result.

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

Foreign Securities Risk. Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or economic instability. There may be less information publicly available about a non-U.S. issuer than a U.S. issuer. Non-U.S. issuers may be subject to different accounting, auditing, financial reporting and investor protection standards than U.S. issuers. Investments in non-U.S. securities may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. With respect to certain countries, there is the possibility of government intervention and expropriation or nationalization of assets. Because legal systems differ, there is also the possibility that it will be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when the Fund does not price its shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell the Fund’s shares. Conversely, shares may trade on days when foreign exchanges are close. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments. Additionally, the Holding Foreign Companies Accountable Act (HFCAA) could cause securities of foreign companies, including ADRs, to be delisted from U.S. stock exchanges if the companies do not allow the U.S. government to oversee the auditing of their financial information. Although the requirements of the HFCAA apply to securities of all foreign issuers, the Securities and Exchange Commission (“SEC”) has thus far limited its enforcement efforts to securities of Chinese companies. If securities are delisted, a fund’s ability to transact in such securities will be impaired, and the liquidity and market price of the securities may decline. The fund may also need to seek other markets in which to transact in such securities, which could increase the fund’s costs.

Infectious Illness Risk. An outbreak of an infectious respiratory illness, like COVID-19, could adversely affect the economies of many nations and the global economy, as well individual issuers and capital markets in ways that cannot be foreseen. The duration of such an outbreak and its effects cannot be predicted with certainty. Any market or economic disruption can be expected to result in elevated tracking error and increased premiums or discounts to the Fund’s NAV.

Issuer Risk. The performance of the Fund depends on the performance of individual securities to which the Fund has exposure. Any issuer of these securities may perform poorly, causing the value of its securities to decline. Poor performance may be caused by poor management decisions, competitive pressures, changes in technology, expiration of patent protection, disruptions in supply, labor problems or shortages, corporate restructurings, fraudulent disclosures, credit deterioration of the issuer or other factors. Issuers may, in times of distress or at their own discretion, decide to reduce or eliminate dividends, which may also cause their stock prices to decline. An issuer may also be subject to risks associated with the countries, states and regions in which the issuer resides, invests, sells products, or otherwise conducts operations.

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.

Market Risk. The Fund could lose money over short periods due to short-term market movements and over longer periods during more prolonged market downturns. The value of a security or other asset may decline due to changes in general market conditions, economic trends or events that are not specifically related to the issuer of the security or other asset, or factors that affect a particular issuer or issuers, exchange or exchanges, country, group of countries, region, market, industry, group of industries, sector or asset class. Local, regional or global events such as war, acts of terrorism, the spread of infectious illness or other public health issues, recessions, or other events could have a significant impact on the Fund and its investments and could result in increased premiums or discounts to the Fund’s NAV. During a general market downturn, multiple asset classes may be negatively affected. Changes in market conditions and interest rates generally do not have the same impact on all types of securities and instruments. Military action by Russia in Ukraine could adversely affect global energy and financial markets and therefore could affect the value of Fund investments, including beyond any direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict and could be substantial.

Micro Capitalization Companies Risk. Micro cap companies may be newly formed or have limited product lines, distribution channels and financial and managerial resources. The risks associated with those investments are generally greater than those associated with investments in the securities of larger, more established companies. This may cause the Fund’s net asset value to be more volatile when compared to investment companies that focus only on large capitalization companies.

Generally, securities of micro capitalization companies are more likely to experience sharper swings in market value, less liquid markets in which it may be more difficult for the adviser to sell at times and at prices that the adviser believes appropriate and generally are more volatile than those of larger companies. Compared to large companies, micro capitalization companies are more likely to have (i) less information publicly available, (ii) more limited product lines or markets and less mature businesses, (iii) fewer capital resources, (iv) more limited management depth and (v) shorter operating histories. Further, the equity securities of micro capitalization companies are often traded over the counter and generally experience a lower trading volume than is typical for securities that are traded on a national securities exchange. Consequently, the Fund may be required to dispose of these securities over a larger period of time (and potentially at less favorable prices) than would be the case for securities of larger companies, offering greater potential for gains and losses and associated tax consequences.

Operational Risk. The Fund is exposed to operational risks arising from a number of 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 and the Adviser seek to reduce these operational risks through controls and procedures. However, these measures do not address every possible risk and may be inadequate to address significant operational risks.

Risk of Investing in the U.S. A decrease in imports or exports, changes in trade regulations and/or an economic recession in the U.S. may have a material adverse effect on the U.S. economy and the securities listed on U.S. exchanges. Proposed and adopted policy and legislative changes in the U.S. are changing many aspects of financial and other regulation and may have a significant effect on the U.S. markets generally, as well as on the value of certain securities. In addition, a continued rise in the U.S. public debt level or the imposition of U.S. austerity measures may adversely affect U.S. economic growth and the securities to which the Fund has exposure.

The U.S. has developed increasingly strained relations with a number of foreign countries. If relations with certain countries continue to worsen, it could adversely affect U.S. issuers as well as non-U.S. issuers that rely on the U.S. for trade. The U.S. has also experienced increased internal unrest and discord. If this trend were to continue, it may have an adverse impact on the U.S. economy and the issuers in which the Fund invests.

Securities Lending Risk. The Fund may engage in securities lending. Securities lending involves the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral. These events could also trigger adverse tax consequences for the Fund. In addition, to the extent loaned securities are not returned in a timely manner, the Fund may be unable to vote proxies for such securities in accordance with its proxy voting policy.

Risk of Reliance on Third-Party Data Sources. The Adviser intends to evaluate its portfolio companies in part through the use of environmental and governance metrics that will be tested, among other ways, through the use of information sourced from publicly available data sources. For example, the environmental and governance criteria used by the Adviser in seeking to encourage accountability, change acceleration or transformational change at the public companies within the Fund’s portfolio incorporates data made available by third parties. In addition, the proxy voting guidelines developed by the Adviser will employ similar metrics that will likewise be evaluated with the assistance of third-party data sources. The data provided by such third parties, though, may be limited or only take into account one, or a few, of many related components of portfolio companies. In addition, environmental and governance information across third party data sources, indexes and other funds may differ substantially and/or be incomparable. As a result, the approach taken by the Fund with respect to a specific portfolio company may differ materially depending upon which third party data source or sources it uses. The Fund’s reliance upon such third-party data sources may also expose it to data errors on the part of such sources.

A Further Discussion of Other Non-Principal Risks

The Fund may also be subject to certain other risks associated with its investments and investment strategies. The order of the below risk factors does not indicate the significance of any particular risk factor.

Close-Out Risk for Qualified Financial Contracts. Regulations adopted by global prudential regulators that are now in effect require counterparties that are part of U.S. or foreign global systemically important banking organizations to include contractual restrictions on close-out and cross-default in agreements relating to qualified financial contracts. Qualified financial contracts include agreements relating to swaps, currency forwards and other derivatives as well as repurchase agreements and securities lending agreements. The restrictions generally prevent the Fund from closing out a qualified financial contract during a specified time period if the counterparty is subject to resolution proceedings and also prohibit the Fund from exercising default rights due to a receivership or similar proceeding of an affiliate of the counterparty. These requirements may increase credit risk and other risks to the Fund.

Derivatives Risk. A derivative is a financial contract, the value of which depends on or is derived from, the value of an underlying asset such as a security or an index. The Fund may invest in certain types of derivatives contracts, including futures. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and the Fund’s losses may be greater if it invests in derivatives than if it invests only in conventional securities.

Foreign Currency Forward Exchange Contracts. Foreign currency forward exchange contracts are transactions involving the Fund’s obligation to purchase or sell a specific currency at a future date at a specified price. Unanticipated changes in currency prices may result in poorer overall performance for the Fund than if it had not entered into foreign currency forward exchange contracts.

Futures. A futures contract is a standardized, exchange-traded agreement to buy or sell a specific quantity of an underlying instrument at a specific price at a specific future time. The risk of loss in buying and selling futures contracts can be substantial. Small price movements in the instrument underlying a futures position may result in immediate and substantial losses to the Fund.

Dividend Risk. There is no guarantee that issuers of the stocks held by the Fund will declare dividends in the future or that, if declared, they will be paid, or that they will either remain at current levels or increase over time.

Threshold/Underinvestment Risk. If certain aggregate and/or fund-level ownership thresholds are reached through transactions undertaken by the Adviser, its affiliates or the Fund, or as a result of third-party transactions or actions by an issuer or regulator, the ability of the Adviser and its affiliates on behalf of clients (including the Fund) to purchase or dispose of investments, or exercise rights or undertake business transactions, may be restricted by regulation or otherwise impaired. The capacity of the Fund to make investments in certain securities may be affected by the relevant threshold limits, and such limitations may have adverse effects on the liquidity and performance of the Fund’s portfolio holdings.

For example, in certain circumstances where the Fund invests in securities issued by companies that operate in certain regulated industries or in certain emerging or international markets, is subject to corporate or regulatory ownership restrictions, or invests in certain futures or other derivative transactions, there may be limits on the aggregate and/or fund-level amount invested or voted by the Adviser and its affiliates for their proprietary accounts and for client accounts (including the Fund) that may not be exceeded without the grant of a license or other regulatory or corporate consent or, if exceeded, may cause the Adviser and its affiliates, the Fund or other client accounts to suffer disadvantages or business restrictions.

Portfolio Holdings Disclosure

A description of the Fund’s policies and procedures regarding the release of portfolio holdings information is available in the Fund’s Statement of Additional Information (“SAI”).

MANAGEMENT

Adviser

TCW, located at 515 South Flower Street, Los Angeles, CA 90071, serves as the Fund’s investment adviser. The Adviser is registered with the SEC as an investment adviser under the Investment Advisers Act of 1940, as amended.

For its investment advisory services to the Fund, the Adviser is paid a management fee from the Fund based on a percentage of the Fund’s average daily net assets, at the annual rate of 0.75%. The Adviser may from time to time voluntarily waive and/or reimburse fees or expenses in order to limit total annual fund operating expenses, as may be specified in a separate letter of agreement.

Pursuant to the Investment Advisory Agreement between TCW and the Trust (entered into on behalf of the Fund), TCW is responsible for substantially all expenses of the Fund, except (i) interest and taxes (including, but not limited to, income, excise, transfer and withholding taxes); (ii) expenses of the Fund incurred with respect to the acquisition, holding, voting and/or disposition of portfolio securities and the execution of portfolio transactions, including brokerage commissions; (iii) expenses incurred in connection with any distribution plan adopted by the Trust in compliance with Rule 12b-1 under the 1940 Act, including distribution fees; (iv) the advisory fee payable to the Adviser hereunder; and (v) litigation expenses (including fees and expenses of counsel retained by or on behalf of the Trust or the Fund) and any fees, costs or expenses payable by the Trust or the Fund pursuant to indemnification obligations to which the Trust or the Fund may be subject (pursuant to contract or otherwise); and (vi) any extraordinary expenses, as determined by a majority of the Independent Trustees.

A discussion regarding the basis for the Board of Trustees’ approval of the Investment Advisory Agreement is available in the Fund’s annual report to shareholders filed on December 27, 2023 (Accession No. 0001829126-23-008225.)

Portfolio Managers

Eli Horton and Molly Landes are jointly and primarily responsible for the day-to-day management of the Fund’s portfolio. Ms. Landes and Mr. Horton are supported by and draw on the resources of the Adviser’s investment personnel, including its data science team and fundamental investment analysts in applying the Adviser’s total value framework.

The Fund’s SAI provides additional information about the Portfolio Managers’ compensation structure, other accounts managed by the Portfolio Managers, and the Portfolio Managers’ ownership of shares in the Fund.

HOW SHARES ARE PRICED

The NAV of shares is determined at the close of regular trading on the New York Stock Exchange (normally 4:00 p.m. Eastern Time) on each day the New York Stock Exchange (“NYSE”) is open. NAV is computed by determining the aggregate market value of all assets of the Fund, less its liabilities, divided by the total number of shares outstanding ((assets-liabilities)/number of shares = NAV). The NYSE is closed on weekends and New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The NAV takes into account the expenses and fees of the Fund, including management, administration, and distribution fees, which are accrued daily. The determination of NAV for the Fund for a particular day is applicable to all applications for the purchase of shares, as well as all requests for the redemption of shares, received by the Fund (or an authorized broker or agent, or its authorized designee) before the close of trading on the NYSE on that day.

Generally, securities traded or dealt in upon one or more securities exchanges (whether domestic or foreign) for which market quotations are readily available and not subject to restrictions against resale shall be valued at the last quoted sales price on the primary exchange or, in the absence of a sale on the primary exchange, at the mean between the current bid and ask prices on such exchange. Securities primarily traded in the National Association of Securities Dealers’ Automated Quotation System (“NASDAQ”) National Market System for which market quotations are readily available shall be valued using the NASDAQ official closing price. Securities that are not traded or dealt in any securities exchange (whether domestic or foreign) and for which over-the-counter market quotations are readily available generally shall be valued at the last sale price or, in the absence of a sale, at the mean between the current bid and ask price on such over-the-counter market. Debt securities not traded on an exchange may be valued at prices supplied by a pricing agent (s) based on broker or dealer supplied valuations or matrix pricing, a method of valuing securities by reference to the value of other securities with similar characteristics, such as rating, interest rate and maturity. Futures, swaps and options contracts listed for trading on a futures or options exchange or board of trade for which market quotations are generally available are valued at the last quoted sale price, or, in the absence of a sale, at the mean of the last bid and ask price. Total return swaps on exchange-listed securities are valued at the last quoted sale price, or, in the absence of a sale, at the mean of the last bid and ask price.

If market quotations are not readily available, securities or other assets will be valued at their fair value as determined in good faith by the Adviser which the Board has appointed as the Fund’s valuation designee pursuant to Rule 2a-5 under the 1940 Act. In these cases, the Fund’s NAV will reflect certain portfolio securities’ fair values rather than their market prices. Fair value pricing involves subjective judgments and it is possible that the fair value determined for a security or other asset may be materially different than the value that could be realized upon the sale of that security or other asset. The fair value prices can differ from market prices. The Adviser may also enlist third party consultants such as an audit firm or financial officer of a security issuer on an as-needed basis to assist in determining a security-specific fair value.

The Fund may use independent pricing services to assist in calculating the value of the Fund’s securities or other assets.

With respect to any portion of the Fund’s assets that are invested in one or more open-end management investment companies registered under the 1940 Act, the Fund’s net asset value is calculated based upon the net asset values of those open-end management investment companies, and the prospectuses for these companies explain the circumstances under which those companies will use fair value pricing and the effects of using fair value pricing.

Premium/Discount Information

Most investors will buy and sell shares of the Fund in secondary market transactions through brokers at market prices and the Fund’s shares will trade at market prices. The market price of shares of the Fund may be greater than, equal to, or less than NAV. Market forces of supply and demand, economic conditions and other factors may affect the trading prices of shares of the Fund.

HOW TO BUY AND SELL SHARES

Shares of the Fund are listed for trading on the Cboe under the symbol SUPP. Share prices are reported in dollars and cents per share. Shares can be bought and sold on the secondary market throughout the trading day like other publicly-traded shares at their market price, and shares typically trade in blocks smaller than a Creation Unit. There is no minimum investment required. Shares may only be purchased and sold on the secondary market when the Cboe is open for trading. The Cboe is open for trading Monday through Friday and is closed on weekends and the following holidays, as observed: New Year’s Day, Martin Luther King, Jr. Day, Presidents’ Day, Good Friday, Memorial Day, Juneteenth National Independence Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

When buying or selling shares through a broker, you will incur customary brokerage commissions and charges, and you may pay some or all of the spread between the bid and the offered price in the secondary market on each leg of a round trip (purchase and sale) transaction.

Authorized Participants may acquire shares directly from the Fund, and Authorized Participants may tender their shares for redemption directly to the Fund, at NAV per share only in large blocks, or Creation Units, of 20,000 shares. Purchases and redemptions directly with the Fund must follow the Fund’s procedures, which are described in the SAI.

The Fund may liquidate and terminate at any time without shareholder approval.

Share Trading Prices

The trading prices of the Fund’s shares in the secondary market generally differ from the Fund’s daily NAV and are affected by market forces such as the supply of and demand for ETF shares and shares of underlying securities held by the Fund, economic conditions and other factors.

Book Entry

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

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

FREQUENT PURCHASES AND REDEMPTIONS OF FUND SHARES

Shares can only be purchased and redeemed directly from the Fund in Creation Units by Authorized Participants, and the vast majority of trading shares occurs on the secondary market. Because the secondary market trades do not directly involve the Fund, it is unlikely those trades would cause the harmful effects of market timing, including dilution, disruption of portfolio management, increases in the Fund’s trading costs and the realization of gains or losses. With regard to the purchase or redemption of Creation Units directly with the Fund, to the extent effected in-kind (i.e., for securities), those trades do not cause the harmful effects that may result from frequent cash trades. To the extent trades are effected in whole or in part in cash, those trades could result in dilution to the Fund and increased transaction costs, which could negatively impact the Fund’s ability to achieve its investment objective. However, direct trading by Authorized Participants is critical to ensuring that shares trade at or close to NAV. The Fund also employs fair valuation pricing to minimize potential dilution from market timing. In addition, the Fund imposes transaction fees on purchases and redemptions of Fund shares to cover the custodial and other costs incurred by the Fund in effecting trades. These fees increase if an investor substitutes cash in part or in whole for securities, reflecting the fact that the Fund’s trading costs increase in those circumstances. Given this structure, the Fund has determined that it is not necessary to adopt policies and procedures to detect and deter market timing of the Fund’s shares.

DIVIDENDS, OTHER DISTRIBUTIONS AND TAXES

Shares are traded throughout the day in the secondary market on the Cboe on an intra-day basis and are created and redeemed in-kind and/or for cash in Creation Units at each day’s next calculated NAV. In-kind arrangements are designed to protect ongoing shareholders from the adverse effects on the Fund’s portfolio that could arise from frequent cash redemption transactions.

Ordinarily, dividends from net investment income, if any, are declared and paid at least annually. The Fund generally distributes its net realized capital gains, if any, to shareholders annually. The Fund may also pay a special distribution at the end of a calendar year to comply with federal tax requirements.

Distributions in cash may be reinvested automatically in additional whole shares only if the broker through whom you purchased shares makes such option available.

Taxes

As with any investment, you should consider how your investment in shares will be taxed. The tax information in this prospectus is provided as general information. You should consult your own tax advisor about the tax consequences of an investment in shares. The Fund has elected, and intends to qualify each year, as a RIC (as defined below) under the Internal Revenue Code of 1986, as amended (the “Code”). As a RIC, the Fund is generally not subject to corporate-level U.S. federal income tax on any net ordinary income or capital gains that are timely distributed to shareholders. However, the Fund’s failure to qualify as a RIC or to meet minimum distribution requirements would result (if certain relief provisions were not available) in corporate-level taxation and, consequently, a reduction in amounts available for distribution to shareholders.

Taxes on Distributions

Distributions of the Fund’s “investment company taxable income” (which is, generally, the Fund’s net ordinary income plus realized net short-term capital gains in excess of realized net long-term capital losses) generally will be taxable as dividend income to U.S. shareholders to the extent of the Fund’s current or accumulated earnings and profits, except that the Fund’s dividends attributable to its “qualified dividend income” (i.e., dividends received on stock of certain domestic and certain foreign corporations with respect to which the Fund satisfies certain holding period and other requirements), if any, generally are subject to federal income tax for non-corporate shareholders who satisfy those requirements with respect to their Fund shares at the rate for net capital gain. A part of the Fund’s dividends also may be eligible for the dividends-received deduction allowed to corporations, subject to similar requirements. The eligible portion may not exceed the aggregate dividends the Fund receives from domestic corporations subject to federal income tax (excluding REITs) and excludes dividends from foreign corporations; certain holding period and other requirements also apply at both the Fund and the shareholder level.

In general, your distributions are subject to federal income tax when they are paid, whether you take them in cash or reinvest them in the Fund (if that option is available). Distributions reinvested in additional shares of the Fund through the means of a dividend reinvestment service, if available, will be taxable to shareholders acquiring the additional shares to the same extent as if such distributions had been received in cash. Distributions of net long-term capital gains, if any, in excess of net short-term capital losses are taxable as long-term capital gains, regardless of how long you have held the shares.

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

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

Distributions in excess of the Fund’s current and accumulated earnings and profits are treated as a tax-free return of capital to the extent of your basis in the shares and as capital gain thereafter. A distribution will reduce the Fund’s NAV per share and may be taxable to you as ordinary income or capital gain (as described above) even though, from an investment standpoint, the distribution may constitute a return of capital.

By law, the Fund is required to withhold a portion of your distributions if you have not provided the Fund with a correct Social Security number or other taxpayer identification number and in certain other situations.

If you are neither a resident nor a citizen of the United States or if you are a foreign entity, distributions (other than capital gain dividends) paid to you by the Fund will generally be subject to a U.S. withholding tax at the rate of 30% unless a lower treaty rate applies. The Fund may, under certain circumstances, report all or a portion of a dividend as an “interest-related dividend” or a “short-term capital gain dividend,” which would generally be exempt from this 30% U.S. withholding tax, provided certain other requirements are met.

Taxes on Exchange-Listed Share Sales

Any capital gain or loss realized upon a sale of shares is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less. The ability to deduct capital losses from sales of shares may be limited.

Taxes on Purchase and Redemption of Creation Units

An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or a loss equal to the difference between the market value of the Creation Units at the time of the exchange and the sum of the exchanger’s aggregate basis in the securities surrendered plus any cash it pays. An Authorized Participant who exchanges Creation Units for securities will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of the securities received plus any cash it receives. The Internal Revenue Service (“IRS”), however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales” or for other reasons. Persons exchanging securities should consult their own tax advisor with respect to whether wash sale rules apply and when a loss might be deductible.

Any capital gain or loss realized upon redemption of Creation Units is generally treated as long-term capital gain or loss if the shares have been held for more than one year and as short-term capital gain or loss if the shares have been held for one year or less.

Authorized Participants who are dealers in securities are subject to the tax rules applicable to dealers, which may result in tax consequences to such Authorized Participants different from those set forth above.

If you purchase or redeem Creation Units, you will be sent a confirmation statement showing how many shares you purchased or sold and at what price. See “Tax Status” in the SAI for a description of the basis determination methods applicable to share redemptions and the Fund’s obligation to report basis information to the IRS.

The foregoing discussion summarizes some of the possible consequences under current federal tax law of an investment in the Fund. It is not a substitute for personal tax advice. Consult your personal tax advisor about the potential tax consequences of an investment in the shares under all applicable tax laws. See “Tax Status” in the SAI for more information.

OTHER INFORMATION

Creations and Redemptions

Prior to trading in the secondary market, shares of the Fund are “created” at NAV by market makers, large investors and institutions only in block-size Creation Units or multiples thereof. Each “creator” or authorized participant (an “Authorized Participant”) has entered into an agreement with the Fund’s distributor. An Authorized Participant is a member or participant of a clearing agency registered with the SEC, which has a written agreement with the Fund or one of its service providers that allows such member or participant to place orders for the purchase and redemption of Creation Units.

A creation transaction, which is subject to acceptance by the Distributor and the Fund, generally takes place when an Authorized Participant deposits into the Fund a designated portfolio of securities, assets or other positions (a “creation basket”), and an amount of cash (including any cash representing the value of substituted securities, assets or other positions), if any, which together approximate the holdings of the Fund in exchange for a specified number of Creation Units. Similarly, shares can be redeemed only in Creation Units, generally for a designated portfolio of securities, assets or other positions (a “redemption basket”) held by the Fund and an amount of cash (including any portion of such securities for which cash may be substituted). The Fund may, in certain circumstances, offer Creation Units partially or solely for cash. Except when aggregated in Creation Units, shares are not redeemable by the Fund. Creation and redemption baskets may differ and the Fund may accept “custom baskets.” More information regarding custom baskets is contained in the Fund’s SAI.

The prices at which creations and redemptions occur are based on the next calculation of NAV after a creation or redemption order is received in an acceptable form under the authorized participant agreement.

Only an Authorized Participant may create or redeem Creation Units with the Fund. Authorized Participants may create or redeem Creation Units for their own accounts or for customers, including, without limitation, affiliates of the Fund.

In the event of a system failure or other interruption, including disruptions at market makers or Authorized Participants, orders to purchase or redeem Creation Units either may not be executed according to the Fund’s instructions or may not be executed at all, or the Fund may not be able to place or change orders.

To the extent the Fund engages in in-kind transactions, the Fund intends to comply with the U.S. federal securities laws in accepting securities for deposit and satisfying redemptions with redemption securities by, among other means, assuring that any securities accepted for deposit and any securities used to satisfy redemption requests will be sold in transactions that would be exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”). Further, an Authorized Participant that is not a “qualified institutional buyer,” as such term is defined in Rule 144A under the Securities Act, will not be able to receive restricted securities eligible for resale under Rule 144A.

Creations and redemptions must be made through a firm that is either a member of the Continuous Net Settlement System of the National Securities Clearing Corporation or a DTC participant that has executed an agreement with the Distributor with respect to creations and redemptions of Creation Unit aggregations. Information about the procedures regarding creation and redemption of Creation Units (including the cut-off times for receipt of creation and redemption orders) is included in the Fund’s SAI.

Because new shares may be created and issued on an ongoing basis, at any point during the life of the Fund a “distribution,” as such term is used in the Securities Act, may be occurring. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner that could render them statutory underwriters subject to the prospectus delivery and liability provisions of the Securities Act. Any determination of whether one is an underwriter must take into account all the relevant facts and circumstances of each particular case.

Broker-dealers should also note that dealers who are not “underwriters” but are participating in a distribution (as contrasted to ordinary secondary transactions), and thus dealing with shares that are part of an “unsold allotment” within the meaning of Section 4(a)(3)(C) of the Securities Act, would be unable to take advantage of the prospectus delivery exemption provided by Section 4(a)(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is available only with respect to transactions on a national securities exchange.

Continuous Offering

The method by which Creation Units of shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of shares are issued and sold by the Fund on an ongoing basis, a “distribution,” as such term is used in the Securities Act, may occur at any point. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery requirement and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent shares and sells the shares directly to customers or if it chooses to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a characterization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in shares, whether or not participating in the distribution of shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. As a result, broker-dealer firms should note that dealers who are not “underwriters” but are participating in a distribution (as contrasted with engaging in ordinary secondary market transactions) and thus dealing with the shares that are part of an overallotment within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act. For delivery of prospectuses to exchange members, the prospectus delivery mechanism of Rule 153 under the Securities Act is only available with respect to transactions on a national exchange.

Dealers effecting transactions in the shares, whether or not participating in this distribution, are generally required to deliver a prospectus. This is in addition to any obligation of dealers to deliver a prospectus when acting as underwriters.

Householding

Please contact your broker-dealer if you are interested in enrolling in householding and receiving a single copy of prospectuses and other shareholder documents, or if you are currently enrolled in householding and wish to change your householding status.

Distribution

The Distributor or its agent distributes Creation Units for the Fund on an agency basis. The Distributor does not maintain a secondary market in shares of the Fund. The Distributor has no role in determining the policies of the Fund or the securities that are purchased or sold by the Fund. The Distributor’s principal address is Three Canal Plaza, Suite 100, Portland, Maine 04101.

The Adviser and its affiliates make payments to certain broker-dealers, registered investment advisers, banks or other intermediaries (together, “intermediaries”) related to marketing activities and presentations, educational training programs, conferences, the development of technology platforms and reporting systems, data provision services, or their making shares of the Fund available to their customers generally and in certain investment programs. Such payments, which may be significant to the intermediary, are not made by the Fund. Rather, such payments are made by the Adviser and its affiliates from their own resources. A financial intermediary may make decisions about which investment options it recommends or makes available, or the level of services provided, to its customers based on the payments or other financial incentives it is eligible to receive. Therefore, such payments or other financial incentives offered or made to an intermediary create conflicts of interest between the intermediary and its customers and may cause the intermediary to recommend the Fund over another investment. More information regarding these payments is contained in the Fund’s SAI.

Please contact your salesperson or other investment professional for more information regarding any such payments his or her firm may receive from the Adviser.

Additional Notices

Shares are not sponsored, endorsed, or promoted by the Cboe. The Cboe makes no representation or warranty, express or implied, to the owners of shares or to any members of the public. The Cboe is not responsible for, nor has it participated in, the determination of the timing of, prices of, or quantities of shares to be issued, nor in the determination or calculation of the equation by which the shares are redeemable. The Cboe has no obligation or liability to owners of shares in connection with the administration, marketing, or trading of the shares. Without limiting any of the foregoing, in no event shall the Cboe have any liability for any lost profits or indirect, punitive, special, or consequential damages even if notified of the possibility thereof.

Derivative Claims of Shareholders

A shareholder may bring a “derivative” action on behalf of the Trust only if certain demand requirements set out in Delaware law and the Trust’s declaration of trust, as amended (the “Declaration”), are met, including (subject to certain exceptions) that the shareholder first make a demand on the Trustees to bring the action themselves unless an effort to cause the Trustees to bring such an action is not likely to succeed. The Declaration provides that shareholders eligible to bring such derivative actions under Delaware law who hold at least 10% of the outstanding shares of the Trust, or 10% of the outstanding shares of the series of the Trust such as the Fund or class to which such action relates, shall join in the request for the Trustees to commence such action. The Declaration also provides that the Trustees shall be entitled to retain counsel or other advisors in considering the merits of the request and may require an undertaking by the shareholders making such request to reimburse the Trust for the expense of any such advisors in the event that the Trustees determine not to bring such action. In addition to all suits, claims or other actions (collectively, “claims”) that under applicable law must be brought as derivative claims, the Declaration provides that each shareholder of the Trust or any series or class thereof agrees that any claim that affects all shareholders of a series or class equally, that is, proportionately based on their number of shares in such series or class, must be brought as a derivative claim subject to the Declaration irrespective of whether such claim involves a violation of the shareholders’ rights under the Declaration or any other alleged violation of contractual or individual rights that might otherwise give rise to a direct claim. The foregoing provisions generally will not operate to limit rights of actions provided to shareholders under the Federal securities laws and brought by such shareholders. The foregoing is intended only as a summary and is qualified in its entirety by reference to the full text of the Declaration, which is on file with the SEC.

FINANCIAL HIGHLIGHTS

The financial highlights table is intended to help you understand the Fund’s financial performance for the past five years or since inception if the Fund has commenced operations within the last five years. Certain information reflects financial results for a single Fund share. The total returns in the table represent the rate that an investor would have earned (or lost) on an investment in the Fund (assuming reinvestment of all dividends and distributions). The information below has been derived from the financial statements audited by Cohen, whose report, along with the Fund’s financial statements, are incorporated by reference in the SAI. The Annual Report to Shareholders and the Fund’s financial statements, as well as the SAI, are available at no cost from the Fund upon request at the toll-free number noted on the back cover to this Prospectus.

PRIVACY NOTICE

The Trust is committed to protecting its investors’ privacy in connection with any investment in a series (“Fund”) of the Trust. Because the Trust sells its shares exclusively to Authorized Participants (as defined in each Fund’s registration statement), which are registered broker-dealers, and does not sell shares directly to individual investors, the Trust does not collect or maintain non-public personal information (such as name, address, phone number, social security number, purchases, sales, account balances, mutual fund account information and other personal financial information) about individual investors. Individual investors make investments in a Fund through a financial intermediary, such as, but not limited to, a broker-dealer, bank, or trust company. Thus, the privacy policy of the relevant financial intermediary governs how the individual investor’s non-public personal information can be shared with nonaffiliated third parties. Based on the foregoing, the Trust has not adopted a privacy policy.
