Managed Futures Strategy Risk. In seeking to achieve its investment objective, the Fund will utilize various investment strategies that involve the use of complex investment techniques, and there is no guarantee that these strategies will succeed. The use of such strategies and techniques may subject the Fund to greater volatility and loss. There can be no assurance that utilizing a certain approach or model will achieve a particular level of return or reduce volatility and loss.

Futures Contracts Risk. Futures contracts have a high degree of price variability and are subject to occasional rapid and substantial changes. There is an imperfect correlation between the change in market value of the futures contracts and the market value of the underlying instrument or reference assets with respect to such contracts. Futures contracts pose the risk of a possible lack of a liquid secondary market, resulting in the potential inability to close a futures contract when desired. Futures contracts are also subject to risks related to possible market disruptions or other extraordinary events, including but not limited to, governmental intervention, and potentially unlimited losses caused by unanticipated market movements. Futures contracts are subject to the possibility that the counterparties to the contracts will default in the performance of their obligations. If the Fund has insufficient cash, it may either have to sell securities from its portfolio to meet daily variation margin requirements with respect to its futures contracts, or close certain positions at a time when it may be disadvantageous to do so. The successful use of futures contracts draws upon the Sub-Advisor's skill and experience with respect to such instruments and is subject to special risk considerations.

Market Risk. The value of the Fund's shares will fluctuate based on the performance of the Fund's investments and other factors affecting the securities markets generally. Certain investments selected for the Fund's portfolio may be worth less than the price originally paid for them, or less than they were worth at an earlier time. The value of the Fund's investments may go up or down, sometimes dramatically and unpredictably, based on current market conditions, such as real or perceived adverse political or economic conditions, tariffs, inflation, changes in interest rates, lack of liquidity in the fixed income markets or adverse investor sentiment.

Geopolitical Events Risk. The interconnectivity between global economies and financial markets increases the likelihood that events or conditions in one region or financial market may adversely impact issuers in a different country, region or financial market. Securities in the Fund's portfolio may underperform due to inflation (or expectations for inflation), interest rates, global demand for particular products or resources, trade disputes, supply chain disruptions, natural disasters, climate change and climate-related events, pandemics, epidemics, terrorism, international conflicts, cybersecurity events, regulatory events and governmental or quasi-governmental actions. The occurrence of global events similar to those in recent years may result in market volatility and may have long-term effects on both the U.S. and global financial markets.

Derivatives Risk. Derivatives include instruments and contracts that are based on, and are valued in relation to, one or more underlying securities, financial benchmarks or indices, such as futures swap agreements and forward contracts. Derivatives typically have economic leverage inherent in their terms. The primary types of derivatives in which the Fund or the Subsidiary invest are futures contracts and forward contracts. Futures contracts and forward contracts can be highly volatile, illiquid and difficult to value, and changes in the value of such instruments held directly or indirectly by the Fund may not correlate with the underlying instrument or reference assets, or the Fund's other investments. Although the value of futures contracts and forward contracts depends largely upon price movements in the underlying instrument or reference asset, there are additional risks associated with futures contracts and forward contracts that are possibly greater than the risks associated with investing directly in the underlying instruments or reference assets, including illiquidity risk, leveraging risk and counterparty credit risk. A small position in futures contracts or forward contracts could have a potentially large impact on the Fund's performance. Trading restrictions or limitations may be imposed by an exchange, and government regulations may restrict trading in futures contracts and forward contracts.

Commodities Risk. Exposure to the commodities markets (including financial futures markets) may subject the Fund, through its investment in the Subsidiary, to greater volatility than investments in traditional securities. Prices of commodities and related contracts may fluctuate significantly over short periods for a variety of reasons, including changes in interest rates, supply and demand relationships and balances of payments and trade; weather and natural disasters; governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies, public health crises and trade or price wars among commodity producers or buyers. The commodity markets are subject to temporary

distortions and other disruptions. U.S. futures exchanges and some foreign exchanges have regulations that limit the amount of fluctuation in futures contract prices which may occur during a single business day. Limit prices have the effect of precluding trading in a particular contract or forcing the liquidation of contracts at disadvantageous times or prices.

Equity Securities Risk. The Fund may have exposure to equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.

Currency Risk. The Fund's exposure to foreign currencies subjects the Fund to the risk that those currencies will decline in value relative to the U.S. Dollar, or, in the case of short positions, that the U.S. Dollar will decline in value relative to the currency that the Fund is short. Currency rates in foreign countries may fluctuate significantly over short periods of time for any number of reasons, including changes in interest rates and the imposition of currency controls or other political developments in the U.S. or abroad.

Credit Risk. Credit risk refers to the possibility that the issuer of the security or a counterparty in respect of a derivative instrument will not be able to satisfy its payment obligations to the Fund when due. Changes in an issuer's credit rating or the market's perception of an issuer's creditworthiness may also affect the value of the Fund's investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer's financial condition changes.

ETF Risks. The Fund is an ETF, and, as a result of an ETF's structure, it is exposed to the following risks:

Authorized Participants, Market Makers, and Liquidity Providers Limitation Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants ("APs"). In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, shares of the Fund ("Shares") may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions.

Cash Redemption Risk. The Fund's investment strategy may require it to redeem Shares for cash or to otherwise include cash as part of its redemption proceeds. The Fund may be required to sell or unwind portfolio investments to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize a capital gain that it might not have recognized if it had made a redemption in-kind. As a result, the Fund may pay out higher annual capital gain distributions than if the in-kind redemption process was used.

Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund's NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility and volatility in the Fund's portfolio holdings, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant. If an investor purchases Shares at a time when the market price is at a premium to the NAV of the Shares or sells at a time when the market price is at a discount to the NAV of the Shares, then the investor may sustain losses that are in addition to any losses caused by a decrease in NAV.

Trading. Although Shares are listed for trading on a national securities exchange, and may be traded on other U.S. exchanges, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund's underlying portfolio holdings, which can be significantly less liquid than Shares.

Leverage Risk. Although the Fund will not borrow funds for trading, the Fund should be considered highly leveraged and is suitable for investors with high tolerance for investment risk. Leverage embedded in the various derivative instruments traded may result in the Fund or its Subsidiary holding positions whose face or notional value may be many times the

Fund's NAV. As a result of this leveraging, even a small movement in the price of a commodity can cause a correspondingly large profit or loss. Losses incurred on leveraged investments increase in direct proportion to the degree of leverage employed. Furthermore, derivative instruments and futures contracts are highly volatile and are subject to occasional rapid and substantial fluctuations. Volatility is a statistical measurement of the variations of returns of a security or fund or index over time. Higher volatility generally indicates high risk. You could lose all or substantially all of your investment in the Fund should the Fund's trading positions suddenly turn unprofitable.

Debt Securities and Fixed-Income Risk. Fixed income securities, such as U.S. Treasuries, or derivatives based on fixed income securities are subject to credit risk and interest rate risk. Credit risk, as described more fully above, refers to the possibility that the issuer of a debt security will be unable to make interest payments or repay principal when it becomes due. Interest rate risk, as described more fully below, refers to fluctuations in the value of a debt security resulting from changes in the general level of interest rates. Prices of fixed income securities tend to move inversely with changes in interest rates. Typically, a rise in rates will adversely affect fixed income security prices and, accordingly, the Fund's returns and share price. In addition, the Fund may be subject to "call" risk, which is the risk that during a period of falling interest rates the issuer may redeem a security by repaying it early (which may reduce the Fund's income if the proceeds are reinvested at lower interest rates), and "extension" risk, which occurs during a rising interest rate environment because certain obligations will be paid off by an issuer more slowly than anticipated (causing the value of those securities held by the Fund to fall).

Interest Rate Risk. Prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short-term or long-term interest rates rise sharply or otherwise change in a manner not anticipated by the Sub-Advisor. The Fund may be subject to heightened interest rate risk due to rising rates as the current period of historically low interest rates may be ending. Interest rate risk is generally greater for fixed-income securities with longer maturities or durations, but increasing interest rates may have an adverse effect on the value of the Fund's investment portfolio as a whole, as investors and markets adjust expected returns relative to such increasing rates. The negative impact on fixed income securities from the resulting rate increases for that and other reasons could be swift and significant.

Management Risk. The Fund is actively managed and may not meet its investment objective based on the portfolio managers' success or failure to implement investment strategies for the Fund.

Models and Data Risk. This is the risk that one or all of the proprietary systematic and quantitative models may fail to identify profitable opportunities at any time. Furthermore, the models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses for the Fund. Models may be predictive in nature and such models may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in losses for the Fund.

Government Securities and Agency Risk. Direct obligations of the U.S. Government such as Treasury bills, notes and bonds are supported by its full faith and credit. Indirect obligations issued by Federal agencies and government-sponsored entities generally are not backed by the full faith and credit of the U.S. Treasury. Accordingly, while U.S. Government agencies and instrumentalities may be chartered or sponsored by Acts of Congress, their securities are neither issued nor guaranteed by the U.S. Treasury. Some of these indirect obligations may be supported by the right of the issuer to borrow from the Treasury; others are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; still others are supported only by the credit of the instrumentality.

Liquidity Risk. The Fund is subject to liquidity risk primarily due to its investments in derivatives. Investments in derivative instruments involve the risk that the Fund may be unable to sell the derivative instrument or sell it at a reasonable price.

Short Position Risk. The Fund will incur a loss as a result of a short position if the price of the short position instrument increases in value between the date of the short position sale and the date on which the Fund purchases an offsetting position. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the ability to accurately anticipate the future value of a security or instrument. The Fund's losses are potentially unlimited in a short position transaction.

Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary's investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by

the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund.

Forward Contracts Risk. Forward contracts involve an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract as agreed by the parties in an amount and at a price set at the time of the contract. At the maturity of a forward contract, a fund may either accept or make delivery of the currency specified in the contract or, at or prior to maturity, enter into a closing transaction involving the purchase or sale of an offsetting contract. The Fund may invest in non-deliverable forwards, which are cash-settled, short-term forward contracts on foreign currencies that are non-convertible and that may be thinly traded or illiquid. The use of forward contracts involves various risks, including the risks associated with fluctuations in foreign currency and the risk that the counterparty will fail to fulfill its obligations.

Tax Risk. The federal income tax treatment of the Fund's income from the Subsidiary may be negatively affected by future legislation, Treasury Regulations (proposed or final), and/or other Internal Revenue Service ("IRS") guidance or authorities that could affect the character, timing of recognition, and/or amount of the Fund's investment company taxable income and/or net capital gains and, therefore, the distributions it makes. If the Fund failed the source of income test for any taxable year but was eligible to and did cure the failure, it could incur potentially significant additional federal income tax expenses. If, on the other hand, the Fund failed to qualify as a RIC for any taxable year and was ineligible to or otherwise did not cure the failure, it would be subject to federal income tax at the fund-level on its taxable income at the regular corporate tax rate (without reduction for distributions to shareholders), with the consequence that its income available for distribution to shareholders would be reduced and distributions from its current or accumulated earnings and profits would generally be taxable to its shareholders as dividend income.

Inflation Risk. At any time, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time.

Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers may cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund's ability to calculate its net asset value, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

Operational Risk. Operational risks include human error, changes in personnel, system changes, faults in communication, and failures in systems, technology, or processes. Various operational events or circumstances are outside the Advisor's or Sub-Advisor's control, including instances at third parties. The Fund, the Advisor and the Sub-Advisor 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 these risks.

Regulatory Risk. Governments, agencies or other regulatory bodies may adopt or change laws or regulations that could adversely affect the issuer, or market value, of an instrument held by the Fund or its Subsidiary or that could adversely impact the Fund's performance.
