The Fund’s investment objective is long-term capital appreciation.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. You may qualify for sales charge discounts on purchases of Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional and is included in the section of the Fund’s prospectus entitled How to Buy Shares on page 115 and Appendix A – Intermediary-Specific Sales Charge Reductions and Waivers, and in the sections of the Fund’s Statement of Additional Information entitled Reduction of Up-Front Sales Charge on Class A Shares on page 63 and Waiver of Up-Front Sales Charge on Class A Shares on page 64.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example only accounts for the Fund’s expense limitation through its expiration period, October 31, 2027, and then depicts the Fund’s total annual expenses thereafter. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. The portfolio turnover rate of the Fund for the fiscal year ended June 30, 2026 was 50% of the average value of its portfolio.

Under normal circumstances, the Fund seeks to provide a total return that exceeds the BNP Paribas Catalyst Systematic Alpha Index III (the “Benchmark”). The Fund seeks excess return, after the impact of fees and expenses, above the Benchmark through investing in (i) securities that provide exposure to the Benchmark (“Benchmark Component”), (ii) securities that provide exposure to strategies of similar nature to the Benchmark components, and (iii) fixed income securities, primarily high quality, short-term U.S. corporate bonds issued by publicly traded companies, including real estate investment trusts (“REITs”) and convertible bonds for collateral management purposes (the “Fixed Income Component”). The Fund generally seeks exposure to the Benchmark by investing in structured notes, non-exchange-traded total return swap contracts, futures contracts and/or forward contracts. These instruments generate returns that approximate the Benchmark’s returns, either in whole or through a combination of the Benchmark’s components, with some or all of the Benchmark exposure instruments being held through a wholly-owned and controlled subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The swap contracts may use the Benchmark or a modified version of the Benchmark, one or more components of the Benchmark, or an unrelated index as the reference asset. The Advisor selects non-Benchmark linked instruments with returns that it believes are highly correlated to those of the Benchmark. BNP Paribas (“BNP”) is the index sponsor and index calculation agent.

Benchmark Component

The Advisor executes the Benchmark Component of the Fund’s strategy by investing in structured notes, swap contracts, futures contracts and/or forward contracts, with some or all of these instruments being held through the Subsidiary. The Benchmark is an absolute return, multi-risk premia index (i.e., a multi-risk factor index) that attempts to capture various sources of systematic

risks in the capital markets, each a Quantitative Investment Strategy (“QIS”). Risk premia refers to sources of return derived by accepting risks beyond those inherent in traditional broad market exposures. Risk premia are considered the building blocks of many variable (i.e., non-linear) and hedged investment strategies. Risk premia strategies typically use publicly traded instruments, tend to have low correlation to equities and bonds, as well as to one another, and have historically had persistent returns over a variety of market environments and time periods. The multi-risk premia strategy Benchmark seeks absolute returns through risk-balanced exposures to carry, momentum and reversal risk premia across the equity, commodity, forex and fixed income markets and synthetically invests in the components of the eleven pre-existing BNP Paribas Risk Premia Indexes (identified in the table below and, collectively, as the “Underlying Indexes”), which consist of futures contracts on equity indices, commodities, government bonds, and currency forwards. Certain Underlying Indexes may have significant exposure to particular countries or geographic regions and, as a result, the Fund may concentrate its investments in such geographic locations.

past to continue to perform poorly. Typical Momentum Risk Premium strategies include being long historically high performing assets and being short historically low performing assets.

The Benchmark uses a rules-based, risk-budget model to dynamically allocate across various Underlying Indexes and is constructed using a hypothetical portfolio comprised of the Underlying Indexes (the “Daily Portfolio”) based on each Underlying Index’s 252 day Historical Volatility, Volatility Budget, and current Daily Portfolio Value. The Benchmark’s exposure to each Underlying Index is determined daily and is greater than or equal to 0.

The Benchmark assigns a higher weight to Underlying Indexes exhibiting near-term low volatility and a lower weight to Underlying Indexes exhibiting near-term high volatility in an attempt to maintain a balanced exposure to the risk in each Carry, Momentum, and Reversal Risk Premia. The Benchmark may rebalance its exposure to the Underlying Indexes as frequently as daily to quickly adapt to various market conditions and risk levels.

The Fund may invest in other QIS beyond or in addition to the Benchmark if, in the opinion of the Advisor, the QIS investments position the Fund to outperform the Benchmark over the long term.

Fixed Income Component

The Fund seeks excess return above the Benchmark through active management of a fixed income portfolio. The Fund’s fixed income portfolio invests primarily in short-term U.S. corporate bonds issued by publicly traded companies, including REITs. The Fund may invest in corporate bonds, including convertible bonds, of any credit quality (with ratings ranging from AAA to C by S&P Global Ratings, or the equivalent by another national recognized statistical ratings organization), effective maturity or modified duration, but intends to hold a majority of the portfolio in investment grade corporate bonds (rated BBB- or higher by S&P Global Ratings, or the equivalent by another nationally recognized statistical ratings organization), with an average effective maturity of less than four years and an average duration of less than three and a half. Modified duration measures the change in the value of a bond in response to a 1% change in interest rates. The Fund will not purchase bonds that are in default.

The Advisor uses quantitative and qualitative screening processes to select bonds for investment by the Fund. The Advisor’s quantitative screen focuses on credit metrics, including total leverage ratio (total debt/earnings before interest, taxes, depreciation and amortization (“EBITDA”)), EBITDA interest coverage ratio (EBITDA/interest expense), and cash ratio (cash and equivalents/current liabilities). The Advisor’s qualitative review involves an analysis of company fundamentals, including business model, competitive advantages, cyclicality of the underlying industry, and addressable market opportunity. The Advisor generally sells bonds if the Advisor believes the bonds no longer offer favorable risk-adjusted return potential.

Investments in Subsidiary

The Advisor executes a portion of the Fund’s strategy by investing up to 25% of its total assets in the Subsidiary. The Subsidiary invests the majority of its assets in structured notes, swap contracts, futures contracts and/or forward contracts that seek to track the Benchmark. The Subsidiary is subject to the same investment restrictions as the Fund, when viewed on a consolidated basis.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Actively Managed Fund Risk. The Fund is actively managed and does not seek to replicate the performance of the Benchmark.

Commodity Risk. Investing in the commodities markets may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, and geological and environmental factors, as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

Convertible Securities Risk. Convertible securities are hybrid securities that have characteristics of both fixed income and equity securities and are subject to risks associated with both fixed income and equity securities. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates rise. The value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates.

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. Credit risk may be substantial for the Fund.

Currency Risk. Fluctuations in exchange rates may adversely affect the market value of the Fund’s investments. Currency risk includes the risk that the currencies in which the Fund has taken a position, or in which the Fund’s investments are denominated, will decline in value. Some currencies are illiquid, and the Fund may not be able to convert them into U.S. dollars, or may only be able to do so at an unfavorable exchange rate. Currency trading involves significant risks, including market risk, interest rate risk, country foreign investment risk, counterparty credit risk, and short sale risk.

Derivatives Risk. Even a small investment in derivatives may give rise to leverage risk (which can increase volatility and magnify the Fund’s potential for loss) and counterparty risk (the risk that a counterparty (the other party to a transaction or an agreement or the party with whom the Fund executes transactions) to a transaction with the Fund may be unable or unwilling to make timely principal, interest or settlement payments), and can have a significant impact on the Fund’s performance. Derivatives are also subject to credit risk (the counterparty may default) and liquidity risk (the Fund may not be able to sell the security or otherwise exit the contract in a timely manner).

Duration Risk. Longer-term securities may be more sensitive to interest rate changes. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities. Effective duration estimates price changes for relatively small changes in rates.

Equity Security Risk. Equity securities, including common stocks, are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in, and perceptions of, their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Forward Contract Risk. Forward contracts are individually negotiated and privately traded, so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

Futures Contract Risk. The successful use of futures contracts draws upon the Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are: (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; (f) if the Fund has insufficient

cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so; and (g) leverage risk.

Geographic Concentration Risk. The Fund may be particularly susceptible to economic, political, regulatory or other events or conditions affecting countries within the specific geographic regions in which the Fund invests. Currency devaluations could occur in countries that have not yet experienced currency devaluation to date, or could continue to occur in countries that have already experienced such devaluations. As a result, the Fund’s net asset value may be more volatile than a more geographically diversified fund.

Interest Rate Risk. Changes in short-term market interest rates will directly affect the yield on the shares of the Fund whose investments are normally invested in floating rate debt. If short-term market interest rates fall, the yield on the Fund’s shares will also fall. Conversely, when short-term market interest rates increase, because of the lag between changes in such short-term rates and the resetting of the floating rates on the floating rate debt in the Fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of mutual funds that do not use such techniques.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities that may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular stocks, futures contracts or other securities in which the Fund invests may prove to be incorrect, and there is no guarantee that the portfolio managers’ judgment will produce the desired results.

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, tariffs or trade wars, international conflicts, and political events affect the securities markets.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Benchmark carry the risk that the ranking system, valuation results, and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Benchmark’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Real Estate and REIT Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These risks may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation.

Security Risk. The value of the Fund may decrease in response to the activities and financial prospects of an individual security or group of securities in the Fund’s portfolio.

Structured Note Risk. The Fund may seek investment exposure to sectors through structured notes that may be exchange-traded or may trade in the over-the-counter market. These notes are typically issued by banks or brokerage firms and have interest and/or principal payments which are linked to changes in the price level of certain assets or to the price performance of certain indices. The value of a structured note will be influenced by time to maturity, level of supply and demand for this type of note, interest rate and market volatility, changes in the issuer’s credit quality rating, and economic, legal, political, or other events that affect the industry.

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The costs of investing in swaps will be indirectly paid by the Fund.

Tax Risk. Certain of the Fund’s investment strategies, including transactions in total return swaps, may be subject to special tax rules, the effect of which may have adverse tax consequences for the Fund. By investing in commodities indirectly through the Subsidiary, the Fund intends to obtain exposure to the commodities markets within the U.S. federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less

favorable rates than capital gains. The Subsidiary declares and distributes a dividend to the Fund, no less than annually, as the sole shareholder of the Subsidiary, in an amount approximately equal to the total amount of “Subpart F” income (as defined in Section 951 of the Internal Revenue Code of 1986, as amended) generated by or expected to be generated by the Subsidiary’s investments during the fiscal year. If the Subsidiary were to fail to make sufficient dividend distributions to the Fund, all or a portion of the income from the Fund’s investment in the Subsidiary might not be qualifying income, and the Fund might not qualify as a regulated investment company for one or more years.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

Volatility Risk. Significant short-term price movements could adversely impact the performance of the Fund. The performance of the Fund is based in part on the prices of one or more of the Benchmark components in which the Fund indirectly invests. The Benchmark components are affected by a variety of factors and may change unpredictably, affecting their value and, consequently, the value and the market price of the Fund’s shares.

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940, as amended, and is not subject to all the investor protections of the 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 operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. Your cost of investing in the Fund will be higher because you indirectly bear the expenses of the Subsidiary. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows the total return of the Fund’s Class A shares for each of the last ten full calendar years. Although Class C and Class I shares have similar annual returns to Class A shares because the classes are invested in the same portfolio of securities, the returns for Class C and Class I shares are different from Class A shares because Class C and Class I shares have different expenses than Class A shares. The performance table shows how the average annual total returns for Class A, Class C and Class I shares compare over time with those of a broad-based market index and the Benchmark. Sales charges are reflected in the information shown below in the table, but the information shown in the bar chart does not reflect sales charges, and, if it did, returns would be lower. How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future. Updated performance information and daily NAV is available at no cost by calling 1-866-447-4228 and on the Fund’s website at www.CatalystMF.com.

Catalyst Systematic Alpha Fund Annual Total Returns

For the Years Ended December 31

During the period shown in the bar chart, the highest return for a quarter was 14.20% (quarter June 30, 2023), and the lowest return for a quarter was (13.42)% (quarter ended December 31, 2018). The Class A shares’ year-to-date return as of September 30, 2026 was 6.84%.

Average Annual Total Returns

(for the periods ended December 31, 2025)

After-tax returns are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and may differ from those shown. After-tax returns are not relevant for shareholders who hold Fund shares in tax-deferred accounts or to shares held by non-taxable entities. After-tax returns are only shown for Class A shares. After-tax returns for other share classes will vary.

The Fund’s investment objective is income and long-term capital appreciation.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. You may qualify for sales charge discounts on purchases of Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional and is included in the section of the Fund’s prospectus entitled How to Buy Shares on page 115 and Appendix A – Intermediary-Specific Sales Charge Reductions and Waivers, and in the sections of the Fund’s Statement of Additional Information entitled Reduction of Up-Front Sales Charge on Class A Shares on page 63 and Waiver of Up-Front Sales Charge on Class A Shares on page 64.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example only accounts for the Fund’s expense limitation through its expiration period, October 31, 2027, and then depicts the Fund’s total annual expenses thereafter. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. The portfolio turnover rate of the Fund for the fiscal year ended June 30, 2026 was 207% of the average value of its portfolio.

The Fund seeks to achieve its investment objective by implementing options strategies on the Standard & Poor’s 500 Index (“S&P 500”), futures contracts on the S&P 500, or similar U.S. stock indexes or their futures contracts, and/or their underlying constituents. Options strategies may include buying and selling options, buying and selling option spreads, and writing covered call options. The Fund also invests collateral in excess of that needed for investing in options strategies in primarily high quality, short-term income-producing securities and cash and cash equivalents, including treasury securities and money market funds.

The Fund may invest in one or more non-exchange-traded total return swap contracts and/or one or more structured notes to gain exposure to some or all of the options strategies. These instruments can provide exposure to a basket of options strategies, including option writing and various options spreads. The options strategies are generally designed to take advantage of certain inefficiencies in the market and typically have a positive carry expectation (i.e., a positive net income expectation from putting on the options positions). The options strategies may implement risk mitigation techniques, including intraday delta hedging, which is a risk management strategy intended to reduce market exposure from written options by establishing offsetting positions in the underlying asset or related instruments. These types of options strategies may also be implemented directly without the use of a total return swap and/or structured note.

The Fund may also implement covered call strategies in which the Fund sells call options on securities it holds to generate premium income and provide partial downside protection. The covered call writing may be implemented directly or included within the basket of options strategies implemented via total return swap contracts and/or structured notes. To the extent the

Fund utilizes covered calls, the Fund intends to write covered call options on stock indexes such as the S&P 500 or on individual large-capitalization stocks.

The Fund also invests in income-producing securities and cash and cash equivalents, some or all of which may serve as margin or collateral for the Fund’s options exposures. The income-producing securities in which the Fund may invest include short-term U.S. corporate bonds (including convertible bonds) and real estate investment trusts (“REITs”). The Fund may invest in corporate bonds of any credit quality (including “junk” bonds), effective maturity or average modified duration; however, under normal circumstances, the Fund intends to hold a majority of its portfolio in investment grade corporate bonds (i.e., those rated BBB or higher by S&P Global Ratings, or the equivalent by another nationally recognized statistical ratings organization).

The Advisor generally intends to hold such bonds to maturity, but may sell any such security if the Advisor believes that the securities no longer offer compelling risk-adjusted return potential.

Distribution Policy: The Fund’s distribution policy is to make twelve monthly distributions to shareholders. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital. Shareholders should not assume that the source of a distribution from the Fund is net profit. For more information about the Fund’s distribution policy, please turn to “Additional Information About the Funds’ Principal Investment Strategies and Related Risks – Principal Investment Strategies – Catalyst Systematic High Income Fund - Distribution Policy and Goals” section in the Fund’s Prospectus.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Call Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received, and gives up the opportunity for gain on the underlying security above the exercise option price. The Fund continues to bear the risk that it will lose money if the value of the security falls below the strike price. As the buyer of a call option, the Fund assumes the risk that the market price of the underlying security will not increase above the strike price plus the premiums paid, so the Fund bears the risk that it will lose the premium paid for the option.

Cash and Cash Equivalents Risk. At any time, the Fund may have significant investments in cash and cash equivalents. When a substantial portion of a portfolio is held in cash and 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.

Convertible Securities Risk. Convertible securities are hybrid securities that have characteristics of both fixed income and equity securities and are subject to risks associated with both fixed income and equity securities. The market value of convertible securities and other debt securities tends to fall when prevailing interest rates increase. The value of convertible securities also tends to change whenever the market value of the underlying common or preferred stock fluctuates.

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The price of a fixed-income security tends to drop if the rating of the underlying issuer drops and the probability of the failure to pay principal and interest increases.

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Distribution Policy Risk. The Fund may, at the discretion of management, target a specific level of monthly distributions (including any return of capital) from time to time. Shareholders receiving periodic payments from the Fund may be under the impression that they are receiving net profits. However, all or a portion of a distribution may consist of a return of capital (i.e., from your original investment). Shareholders should not assume that the source of a distribution from the Fund is net profit. Shareholders should note that return of capital will reduce the tax basis of their shares and potentially increase the taxable gain, if any, upon disposition of their shares.

Equity Security Risk. Equity securities, including common stocks, are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Fixed Income Risk. When the Fund invests in fixed income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, a increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could

affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Hedging Risk. Hedging is a strategy in which the Fund uses a derivative to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk, or that hedging transactions will be either available or cost effective.

Index Risk. If the derivative is linked to the performance of an index, it will be subject to the risks associated with changes in that index.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities.

Junk Bond Risk. Lower-quality bonds, known as “high yield” or “junk” bonds, present greater risk than bonds of higher quality, including an increased risk of default. An economic downturn or period of rising interest rates could adversely affect the market for these bonds and reduce the Fund’s ability to sell its bonds. The lack of a liquid market for these bonds could decrease the Fund’s share price.

Large Capitalization Company 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.

Leverage Risk. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile. The use of leverage may cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations. The use of leverage may also cause the Fund to have higher expenses than those of mutual funds that do not use such techniques.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and, if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular securities, options, and futures contracts or other derivatives in which the Fund invests may prove to be incorrect, and there is no guarantee that the portfolio managers’ judgment will produce the desired results.

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, tariffs and trade wars, international conflicts, and political events affect the securities markets.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Advisor carry the risk that the ranking system, valuation results, and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the fund to effectively implement its investment strategy and achieve its objectives and could potentially lead to significant losses.

Options Risk. The Fund’s strategy involves the sale and purchase of call and put options. A seller (writer) of a call option will lose money if the underlying security on which the option was written increases in value to a level above the strike price of the sold option plus the premium received. Since there is no limit on how high a value of an entity can go, there is material risk in being short a call with no offsetting position. A seller (writer) of a put option will lose money if the underlying security on which the option was written decreases in value to a level below the strike price of the sold option less the premium received. The seller of a put option is limited to losing the difference between the strike price less the premium received and $0, reflecting a full loss of all value for the underlying security. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction. A seller of an option can be liquidated if the value of the underlying security advances enough in the case of a call option or declines enough in the case of a put option, given there are no offsetting positions or enough capital to offset the unrealized losses. In a liquidation event, one should expect material realized losses.

A buyer of a call or put option risks the loss of the entire premium invested in the option. If the underlying security is not above the strike price at maturity of a call, or not below the strike price at maturity of a put, the option will expire worthless.

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated

as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark), and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

Real Estate and REIT Risk. The Fund is subject to the risks of the real estate market as a whole, such as taxation, regulations, and economic and political factors that negatively impact the real estate market and the direct ownership of real estate. These risks may include decreases in real estate values, overbuilding, rising operating costs, interest rates, and property taxes. In addition, some real estate related investments are not fully diversified and are subject to the risks associated with financing a limited number of projects. REITs are heavily dependent upon the management team and are subject to heavy cash flow dependency, defaults by borrowers, and self-liquidation.

Regulatory Risk. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective, and could increase the operating expenses of the Fund.

Structured Note Risk. The Fund may seek investment exposure to sectors through structured notes that may be exchange-traded or may trade in the over-the-counter market. These notes are typically issued by banks or brokerage firms and have interest and/or principal payments which are linked to changes in the price level of certain assets or to the price performance of certain indices. The value of a structured note will be influenced by time to maturity, level of supply and demand for this type of note, interest rate and market volatility, changes in the issuer’s credit quality rating, and economic, legal, political, or other events that affect the industry.

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The costs of investing in swaps will be indirectly paid by the Fund.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying fund. By investing in underlying funds, you will bear not only your proportionate share of the funds’ expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

U.S. Government Obligations Risk. The Fund may invest in U.S. government or agency obligations. Securities issued or guaranteed by federal agencies and U.S. government sponsored entities may or may not be backed by the full faith and credit of the U.S. government.

Volatility Risk. The Fund’s performance may be volatile, which means that the Fund’s performance may be subject to substantial short-term changes up or down.

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows the total return of the Fund’s Class A shares for each of the last ten full calendar years. Although Class Cand Class I shares have similar annual returns to Class A shares because the classes are invested in the same portfolio of securities, the returns for Class Cand Class I shares are different from Class A shares because Class C and Class I shares have different expenses than Class A shares. The performance table shows how the average annual total returns for Class A, Class C and Class I shares compare over time with those of a broad-based market index. Sales charges are reflected in the information shown below in the table, but the information shown in the bar chart does not reflect sales charges, and, if it did, returns would be lower.

The Fund acquired all of the assets and liabilities of Harbor Assets, LLC (the “Predecessor Fund”) in a tax-free reorganization on August 30, 2013 (the “Reorganization”). In connection with the Reorganization, shares of the Predecessor Fund were exchanged for Class A shares of the Fund. Prior to November 1, 2025, the Fund was managed by a sub-advisor with different investment strategies and policies. The performance data below for periods prior to November 1, 2025 reflects a different sub-advisor with a different investment strategy. Consequently, the performance record may be less pertinent for investors considering whether to purchase shares of the Fund. The Fund’s performance may have been different if the Fund’s portfolio was managed under the current investment objective, strategies and policies.

Fund performance was materially impacted by a nonrecurring litigation settlement of $1.96 million booked to the Fund on June 19, 2023. The positive impact was $0.1482/share, or 1.65% of the Fund’s NAV.

How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

Catalyst Systematic High Income Fund Annual Total Returns

For the Years Ended December 31

During the period shown in the bar chart, the highest return for a quarter was 6.22% (quarter ended September 30. 2016), and the lowest return for a quarter was (16.96)% (quarter ended March 31, 2017). The Class A shares year-to-date return as of September 30, 2026 was 10.12%.

Average Annual Total Returns

(for the periods ended December 31, 2025)

After-tax returns for the Fund are calculated using the highest historical individual federal marginal income tax rate and do not reflect the impact of state and local taxes. Actual after-tax returns depend on a shareholder’s tax situation and may differ from those shown. After-tax returns are not relevant for shareholders who hold Fund shares in tax-deferred accounts or to shares held by non-taxable entities. After-tax returns are only shown for Class A shares. After-tax returns for other share classes will vary.

The Fund’s investment objective is long-term capital appreciation.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. You may qualify for sales charge discounts on purchases of Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional and is included in the section of the Fund’s prospectus entitled How to Buy Shares on page 115 and Appendix A – Intermediary-Specific Sales Charge Reductions and Waivers and in the sections of the Fund’s Statement of Additional Information entitled Reduction of Up-Front Sales Charge on Class A Shares on page 63 and Waiver of Up-Front Sales Charge on Class A Shares on page 64.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example only accounts for the Fund’s expense limitation through its expiration period, October 31, 2027, and then depicts the Fund’s total annual expenses thereafter. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. The portfolio turnover rate of the Fund for the fiscal year ended June 30, 2026 was 0% of the value of its portfolio.

Under normal market conditions, the Fund seeks to achieve its investment objective by investing in put and call options on exchange traded funds (“ETFs”) that track the S&P 500 Index (“Index ETFs”) and in fixed income securities. At time of purchase, the equity options component’s target allocation is between 0.5% and 7.5%, while the fixed income component’s target allocation is between 92.5% and 99.5%. The equity option component is designed to provide 100% notional exposure to the S&P 500 Index (the “Index”), with a level of hedge on the downside and participation on the upside to a certain cap. Using a combination of put and call options on Index ETFs, the Fund’s investment sub-advisor, Exceed Advisory LLC (the “Sub-Advisor”), initially executes the equity options strategy by seeking to provide an investment vehicle that limits losses to 12.5% when the Index declines in value, and to participate in increases in the Index up to approximately 15%. As the Index increases in value, the strategy seeks to increase the level of hedge on the downside and the cap on the upside by rebalancing or rolling the call and put strike levels in a given maturity to higher strike levels. By rebalancing, the strategy seeks to optimize risk / reward by lowering downside risk (through buying higher strike puts) and increasing upside potential (through selling higher strike calls), thus converting a hard cap to a soft cap. There may be times that the Sub-Advisor determines not to implement the Fund’s hedging strategy.

The fixed income component is designed to return a yield that is used to assist in purchasing the equity option component. The equity options strategy is intended to provide investment returns that are correlated with, but less volatile than, those of the Index. Although the option strategy includes a leverage component, the strategy also limits the Fund’s participation in Index gains.

Equity Options Component

The equity options strategy consists of exchange traded equity options. Options selected for the equity options component generally have a duration of approximately one year.

Put Options Sub-Component

Put options allow the purchaser, for a premium, to “put” a security to the seller of the option at a strike price. Put options are selected for the Fund to target participation in the Index if the Index decreases down to a maximum floor of 12.5% by selecting a short put whose strike price equals the current value of the Index and a long put whose strike price is below the current value of the Index. The Fund’s purchases and sales of put options result in “put spreads,” which are intended to allow the Fund to mitigate losses in the equity options component when the Index declines by more than 12.5% during the terms of the put spreads. The put spreads do not guard the Fund against Index losses in the equity options component of less than 12.5%, and only seeks to guard against such losses during the terms of the put spreads. All other losses in the equity options component will be borne by the Fund and shareholders. There is no guarantee that the put spreads will limit the losses in the equity options component to 12.5%. Put options do not protect against losses in the fixed income component of the Fund’s strategy.

Call Options Sub-Component

Call options allow the purchaser, for a premium, to “call” away a security from the seller of the option at a particular price, called the “strike price.” Normally, a buyer calls away a security at the strike price if the security’s market price is greater than the strike price. The call options are selected to target participation in the Index if the Index increases up to a maximum cap by selecting a long call whose strike price equals the current value of the Index and a short call whose strike price is above the current value of the Index. In this way, the Fund seeks to participate with the market up to the maximum cap. The Fund’s purchases and sales of call options result in “call spreads,” which are intended to allow the Fund to participate in increases in the Index up to approximately 15% during the terms of the call spreads.

The objective of the call options is to provide market participation up to the maximum cap while the objective of the put options is to provide a floor to negative performance and thereby limit exposure in a materially bearish environment. However, there is no guarantee that put and call options will limit the Fund’s losses in the equity options component.

Fixed Income Component

The fixed income component of the Fund’s portfolio consists of domestic short to medium term, investment grade, fixed coupon, senior or subordinated corporate bonds, and government securities with a typical maturity of 5 years or less, or ETFs that invest primarily in such securities. The Fund typically invests primarily in corporate debt. Fixed income securities are selected by

identifying the highest yielding securities among a peer group with similar credit quality and maturity, while also ensuring portfolio diversification in terms of credit rating and industry.

Although the Fund’s strategy seeks to provide protection for large losses in the equity portion of the portfolio, an investor can still lose money on the fixed income portion such that the total loss in the portfolio as a whole could be more than the targeted 12.5%.

The Fund actively trades its portfolio investments, which may lead to higher transaction costs that may affect the Fund’s performance.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Call Options Risk. As the seller (writer) of a covered call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received and gives up the opportunity for gain on the underlying security above the exercise option price. The Fund continues to bear the risk that it will lose money if the value of the security falls below the strike price. As the buyer of a call option, the Fund assumes the risk that the market price of the underlying security will not increase above the strike price plus the premiums paid, so the Fund bears the risk that it will lose the premium paid for the option.

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Credit Risk. An issuer of a security may fail to pay principal and interest in a timely manner, reducing the Fund’s total return. The price of a fixed-income security tends to drop if the rating of the underlying issuer drops and the probability of the failure to pay principal and interest increases.

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Equity Options Strategy Risk. Although the equity options strategy is intended to manage volatility, it may not protect against market declines, may limit the Fund’s participation in market gains (particularly during periods when market values are increasing or market volatility is high), may increase portfolio transaction costs (which could result in losses or reduction in gains), may not be successful, and is subject to the Sub-Advisor’s ability to correctly analyze and implement the Fund’s equity options strategy.

Equity Security Risk. Equity securities are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Exchange Traded Funds (“ETFs”) Risk. Like an open-end investment company (mutual fund), the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop; and (iii) market trading in the ETF may be halted under certain circumstances.

Fixed-Income Risk. When the Fund invests in fixed-income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline. Other risk factors include credit risk (the debtor may default) and prepayment risk (the debtor may pay its obligation early, reducing the amount of interest payments). These risks could affect the value of a particular investment by the Fund, possibly causing the Fund’s share price and total return to be reduced and fluctuate more than other types of investments.

Hedging Risk. Hedging is a strategy in which the Fund uses a derivative to offset the risks associated with other Fund holdings. There can be no assurance that the Fund’s hedging strategy will reduce risk or that hedging transactions will be either available or cost effective.

Index Risk. If the derivative, such as a futures contract, in which the Fund invests is linked to the performance of an index, it will be subject to the risks associated with changes in that index.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. Rising interest rates pose a heightened risk to the Fund’s longer-term fixed income securities.

Large Capitalization Company 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.

Leverage Risk. Using leverage can magnify the Fund’s potential for gain or loss and; therefore, amplify the effects of market volatility on the Fund’s share price. Using derivatives can create leverage, which can amplify the effects of market volatility on the Fund’s share price and make the Fund’s returns more volatile.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Managed Volatility Risk. Techniques used by the Sub-Advisor to manage the volatility of the Fund’s investments carry the risks that such techniques may not protect against market declines. The techniques may also limit the Fund’s participation in market gains, particularly during periods where market values are increasing but market volatility is high. Further, such techniques may increase portfolio transaction costs, which could result in losses or reduced gains. They also may not be successful, as the techniques are subject to the Sub-Advisor’s ability to correctly analyze and implement the volatility management techniques in a timely manner.

Management Risk. The portfolio manager’s judgments about the attractiveness, value and potential appreciation of particular stocks, options, or other securities or derivatives in which the Fund invests or sells short may prove to be incorrect, and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market Risk. Overall stock market risks may also affect the value of the Fund. Factors such as domestic economic growth and market conditions, interest rate levels, tariffs or trade wars, international conflicts, and political events affect the securities markets.

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives, and could potentially lead to significant losses.

Options Risk. There are risks associated with the Fund’s options strategy. This strategy involves the sale and purchase of call and put options. A seller (writer) of a call option will lose money if the underlying security on which the option was written increases in value to a level above the strike price of the sold option plus the premium received. Since there is no limit on how high the

value of an entity can go, there is material risk in being short a call with no offsetting position. A seller (writer) of a put option will lose money if the underlying security on which the option was written decreases in value to a level below the strike price of the sold option less the premium received. The seller of a put option is limited to losing the difference between the strike price less the premium received and $0, reflecting a full loss of all value for the underlying security. The Fund’s losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction. A seller of an option can be liquidated if the value of the underlying security advances enough in the case of a call option, or declines enough in the case of a put option, given there are no offsetting positions or enough capital to offset the unrealized losses. In a liquidation event, one should expect material realized losses.

A buyer of a call or put option risks the loss of the entire premium invested in the option. If the underlying security is not above the strike price at maturity of a call, or not below the strike price at maturity of a put, the option will expire worthless.

Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time, and changes in volatility. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of the Fund’s portfolio securities. Further, the underlying reference instrument on which the option is based may have imperfect correlation to the value of the Fund’s portfolio securities. Option premiums are treated as short-term capital gains and, when distributed to shareholders, are usually taxable as ordinary income, which may have a higher tax rate than long-term capital gains for shareholders holding Fund shares in a taxable account. Options are also subject to leverage and volatility risk, liquidity risk, tracking risk (the risk that an option’s returns will deviate from a benchmark), and sub-strategy risk (the risk that hedging sub-strategies will not perform as expected).

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.

Turnover Risk. The Fund may have a high turnover of the securities held in its portfolio. Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its

investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

U.S. Government Obligations Risk. The Fund may invest in U.S. government or agency obligations. Securities issued or guaranteed by federal agencies and U.S. government sponsored entities may or may not be backed by the full faith and credit of the U.S. government.

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows performance of the Fund’s Class I shares for each of the last ten full calendar years. Although Class A and Class C shares have similar annual returns to Class I shares because the classes are invested in the same portfolio of securities, the returns for Class A shares and Class C shares are different than Class I shares because Class A and Class C shares have different expenses than Class I shares. The performance table shows how the average annual total returns for Class I, Class A and Class C shares compare over time with those of a broad-based market index.

The Fund acquired all of the assets and liabilities of Exceed Defined Shield Index Fund, a series of Forum Funds, (the “Predecessor Fund”) in a tax-free reorganization on September 1, 2017 (the “Reorganization”). In connection with this Reorganization, shares of the Predecessor Fund’s Investor Shares and Institutional Shares were exchanged for Class A shares and Class I shares of the Fund, respectively. The Predecessor Fund had an investment objective and strategies that were, in all material respects, the same as those of the Fund, and was managed in a manner that, in all material respects, complied with the investment guidelines and restrictions of the Fund. The performance information set forth below for periods prior to September 1, 2017 reflects the historical performance of the Predecessor Fund shares. Neither Investor Class nor Institutional Class shares of the Predecessor Fund charged a sales load and, therefore, the impact of a sales load is not reflected in the Fund’s performance for the periods prior to September 1, 2017. Additionally, because the 1 Year Average Annual Total Returns assume investment in the Fund on December 31, 2016, which was prior to the Reorganization, the impact of a sales load is not reflected in the performance information provided.

How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and Example below. You may qualify for sales charge discounts on purchases of Class A shares if you and your family invest, or agree to invest in the future, at least $50,000 in the Fund. More information about these and other discounts is available from your financial professional and is included in the section of the Fund’s prospectus entitled How to Buy Shares on page 115 and Appendix A – Intermediary-Specific Sales Charge Reductions and Waivers, and in the sections of the Fund’s Statement of Additional Information entitled Reduction of Up-Front Sales Charge on Class A Shares on page 63 and Waiver of Up-Front Sales Charge on Class A Shares on page 64.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated, and then hold or redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. The portfolio turnover rate of the Fund for the fiscal year ended June 30, 2026 was 11% of the average value of its portfolio.

The Fund seeks to achieve its investment objective by investing in a portfolio comprised of (i) futures contracts, forward and spot contracts, and/or options on futures contracts, or swaps on the preceding or baskets of the preceding, on or related to the following sectors: currencies, interest rate instruments, stock indices, metals, energy and agricultural commodities, (the “Futures Component”), and (ii) equity exchange traded funds (“ETFs”), currently implemented via a portfolio of ETFs, but may also be implemented and/or augmented by single-name or baskets of equity securities, and common stocks (the “Equity Component”), intended to capitalize on the non-correlated, long term historical performance of the equities and managed futures asset classes The Fund also holds a large portion of its assets in cash, money market mutual funds, U.S. Treasury Securities, and other cash equivalents, some or all of which will serve as margin or collateral for the Fund’s investments.

Futures Component

The Futures Component of the Fund’s portfolio may hold long and short positions on futures contracts, forward and spot contracts and options on futures contracts and indices, or swaps on or baskets of the preceding holdings, and maintains cash and cash equivalents to be utilized as margin or collateral. The Fund invests 30% to 70% of its assets in the Futures Component. The Futures Component of the Fund’s assets are allocated among various asset classes, including equity, fixed income, commodities and currencies. Investments may be made in domestic and foreign markets, including emerging markets. Investment in these instruments may be made by the Fund directly or indirectly by investing through its Subsidiary (as described below).

The Fund’s sub-advisor, Millburn Ridgefield LLC (the “Sub-Advisor”), utilizes a set of proprietary trading systems developed by the Sub-Advisor to determine the Fund’s asset allocations. The trading systems generate buy or sell decisions in a particular market based on the analysis of technical market information (such as price, liquidity, and transaction costs) and/or non-price economic variables (such as economic statistics, interest rates, and supply/demand measures). The trading systems analyze these factors over a broad time spectrum that may range from several minutes to multiple years. The Sub-Advisor analyzes a number of additional factors

in determining how the markets traded are allocated in the portfolio, including, but not limited to: profitability of an asset class or market; liquidity of a particular market; professional judgement; desired diversification among markets and asset classes; transaction costs; exchange regulations; and depth of market. Decisions whether to trade a particular market require the exercise of judgment. The decision not to trade certain markets for certain periods, or to reduce the size of a position in a particular market, may at times result in missing significant profit opportunities. The allocations are reviewed at least monthly, although changes may occur more or less frequently.

Equity Component

The Equity Component is intended to provide the Fund’s portfolio with long-term, strategic exposure to a number of U.S. and international liquid equity securities. The companies and/or ETFs held by the Fund may be of any market capitalization, sector and geographic location (including emerging markets). The Fund invests 30% to 70% of its assets in the Equity Component. The Fund’s Equity Component investments are taken on a relatively passive, long-only, “buy-and-hold” basis.

The Fund actively trades its portfolio investments, which may lead to higher transaction costs that may affect the Fund’s performance.

Investments in Subsidiary

The Sub-Advisor executes a portion of the Fund’s strategy by investing up to 25% of its total assets in a wholly-owned and controlled subsidiary (the “Subsidiary”). The Subsidiary invests the majority of its assets in commodities and other futures contracts. The Subsidiary is subject to the same investment restrictions as the Fund, when viewed on a consolidated basis.

As with any mutual fund, there is no guarantee that the Fund will achieve its objective. Investment markets are unpredictable and there will be certain market conditions where the Fund will not meet its investment objective and will lose money. The Fund’s net asset value and returns will vary and you could lose money on your investment in the Fund, and those losses could be significant.

The following summarizes the principal risks of investing in the Fund. These risks could adversely affect the net asset value, total return, and value of the Fund and your investment.

Agricultural Sector Risk. Economic forces, including forces affecting agricultural markets, as well as government policies and regulations affecting agriculture companies, could adversely impact the Fund’s investments. Soft commodities, grains and livestock production, and trade flows are significantly affected by government policies and regulations.

Allocation Risk. If a Fund’s strategy for allocating assets among different asset classes does not work as intended, the Fund may not achieve its objective or may underperform other funds with the same or similar investment strategy.

Cash and Cash Equivalents Risk. At any time, the Fund may have significant investments in cash and cash equivalents. When a substantial portion of a portfolio is held in cash and 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.

Commodity Risk. Investing in the commodities markets may subject the Fund to greater volatility than investments in traditional securities. Commodity prices may be influenced by unfavorable weather, animal and plant disease, and geological and environmental factors, as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

Counterparty Risk. A counterparty to a financial instrument held by the Fund, or by a special purpose or structured vehicle invested in by the Fund, may become insolvent or otherwise fail to perform its obligations, and the Fund may obtain no or limited recovery of its investment, and any recovery may be significantly delayed.

Currency Risk. Fluctuations in exchange rates may adversely affect the market value of a Fund’s investments. Currency risk includes the risk that the currencies in which a Fund has taken a position, or in which a Fund’s investments are denominated, will decline in value. Some currencies are illiquid, and a Fund may not be able to convert them into U.S. dollars, or may only be able to do so at an unfavorable exchange rate. Currency trading involves significant risks, including market risk, interest rate risk, foreign investment risk, counterparty credit risk, and short sale risk.

Derivatives Risk. The use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments. These risks include (i) the risk that the counterparty to a derivative transaction may not fulfill its contractual obligations; (ii) the risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. Derivative prices are highly volatile and may fluctuate substantially during a short period of time.

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Emerging market economies may be based on only a few industries, and security issuers may be more susceptible to economic weakness and more likely to default. Emerging market securities also tend to be less liquid. There may also be less reliable or publicly available information about emerging markets due to non-uniform regulatory, auditing or financial recordkeeping standards, which could cause errors in the implementation of the Fund’s investment strategy. The Fund’s performance may depend on issues other than those that affect U.S. companies and may be adversely affected by different rights and remedies associated with emerging market investments, or the lack thereof, compared to those associated with U.S. companies.

Energy Sector Risk. Because of the Fund’s exposure to this sector, the performance of the Fund is tied closely to and affected by developments in the energy sector, such as the possibility that government regulation will negatively impact companies in this sector. Energy infrastructure entities are subject to the risks specific to the industry they serve.

Equity Security Risk. Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. Investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic and banking crises.

Exchange-Traded Funds (“ETFs”) Risk. Like an open-end investment company (mutual fund), the value of an ETF can fluctuate based on the prices of the securities owned by the ETF, and ETFs are also subject to the following additional risks: (i) the ETF’s market price may be less than its net asset value; (ii) an active market for the ETF may not develop; and (iii) market trading in the ETF may be halted under certain circumstances.

Fixed-Income Risk. When the Fund invests in fixed-income securities, the value of an investment in the Fund will fluctuate with changes in interest rates. Typically, an increase in interest rates causes a decline in the value of fixed income securities owned by the Fund. In general, the market price of fixed income securities with longer maturities will increase or decrease more in response to changes in interest rates than shorter-term securities. Federal Reserve policy changes may expose fixed-income and related markets to heightened volatility and may reduce liquidity for certain Fund investments, which could cause the value of the Fund’s investments and share price to decline.

Foreign Exchanges Risk: A portion of the derivatives trades made by the Fund may take place on foreign markets. Neither existing CFTC regulations nor regulations of any other U.S. governmental agency apply to transactions on foreign markets. Some of these foreign markets, in contrast to U.S. exchanges, are so-called principals’ markets in which performance is the responsibility only of the individual counterparty with whom the trader has entered into a commodity interest transaction and not of the exchange or clearing corporation. In these kinds of markets, there is risk of bankruptcy or other failure or refusal to perform by the counterparty.

Foreign Investment Risk. Foreign investing involves risks not typically associated with U.S. investments, including adverse fluctuations in foreign currency values, adverse political, social and economic developments, less liquidity, greater volatility, less developed or less efficient trading markets, political instability, and differing auditing and legal standards. Investing in emerging markets imposes risks different from, or greater than, the risks of investing in foreign developed countries.

Forward Contract Risk. Forward contracts are individually negotiated and privately traded, so they are dependent upon the creditworthiness of the counterparty and subject to counterparty default risk and liquidity risk. If a counterparty defaults and fails to deliver or settle a forward trade, replacing the transaction may be costly. Liquidity risk exists because no organized secondary market exists to trade or dispose of forward obligations.

Futures Contract Risk. The successful use of futures contracts draws upon the Advisor’s or Sub-Advisor’s skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures a contracts are (a) the imperfect correlation between the change in market value of the instruments held by the Fund and the price

of the futures contract; (b) possible lack of a liquid secondary market for a futures contract and the resulting inability to close a futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Advisor’s or Sub-Advisor’s inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

Interest Rate Risk. Overall bond prices, including the prices of securities held by the Fund, may decline over short or even long periods of time due to rising interest rates. Bonds with longer maturities tend to be more sensitive to interest rates than bonds with shorter maturities. Rising interest rates may pose a heightened risk to the Fund’s longer-term fixed income securities.

Leverage Risk. Using derivatives like futures, forwards, options and swaps to increase the Fund’s combined long and short exposure creates leverage, which can magnify the Fund’s potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund’s share price.

Liquidity Risk. Liquidity risk exists when particular investments are difficult to sell. Although most of the Fund’s securities must be liquid at the time of investment, the Fund may purchase illiquid investments and securities may become illiquid after purchase by the Fund, particularly during periods of market turmoil. When the Fund holds illiquid investments, the Fund’s investments may be harder to value, especially in changing markets, and if the Fund is forced to sell these investments to meet redemptions or for other cash needs, the Fund may suffer a loss. In addition, when there is illiquidity in the market for certain securities, the Fund, due to limitations on investments in illiquid investments, may be unable to achieve its desired level of exposure to a certain sector.

Management Risk. The portfolio managers’ judgments about the attractiveness, value and potential appreciation of particular asset classes, securities and derivatives in which the Fund invests may prove to be incorrect, and there is no guarantee that the portfolio manager’s judgment will produce the desired results.

Market Risk. Overall securities and derivatives market risks may affect the value of individual instruments in which the Fund invests. Factors such as domestic and foreign economic growth and market conditions, interest rate levels, tariffs or trade wars, international conflicts, and political events affect the securities and derivatives markets. When the value of the Fund’s investments goes down, your investment in the Fund decreases in value and you could lose money.

Metals Sector Risk. The prices of precious metals and industrial metals operation companies are affected by the price of precious metals such as platinum, palladium and silver, as well as other metals prices and prevailing market conditions. These prices may be volatile, fluctuating substantially over short periods of time.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor carry the risk that the ranking system, valuation results and predictions might be based on one or more incorrect assumptions, insufficient historical data, inadequate design, or may not be

suitable for the purpose intended. In addition, models may not perform as intended for many reasons, including errors, omissions, imperfections or malfunctions. Because the use of models are usually based on data supplied by third parties, the success of the Sub-Advisor’s use of such models is dependent on the accuracy and reliability of the supplied data. Historical data inputs may be subject to revision or corrections, which may diminish data reliability and quality of predictive results. Changing and unforeseen market dynamics could also lead to a decrease in the short-term or long-term effectiveness of a model. Models may lose their predictive validity and incorrectly forecast future market behavior and asset prices, leading to potential losses. No assurance can be given that a model will be successful under all or any market conditions.

Options Market Risk. Markets for options may not always operate on a fair and orderly basis. At times, prices for options may not represent fair market value and prices may be subject to manipulation, which may be extreme under some circumstances. The dysfunction and manipulation of volatility and options markets may make it difficult for the Fund to effectively implement its investment strategy and achieve its objectives, and could potentially lead to significant losses.

Options Risk. There are risks associated with the sale and purchase of call and put options. As the seller (writer) of a call option, the Fund assumes the risk of a decline in the market price of the underlying security below the purchase price of the underlying security less the premium received, and gives up the opportunity for gain on the underlying security above the exercise option price. Because they are unhedged, the Fund’s written calls expose the Fund to potentially unlimited losses.

Regulatory Risk. Changes in the laws or regulations of the United States or other countries, including any changes to applicable tax laws and regulations, could impair the ability of the Fund to achieve its investment objective, and could increase the operating expenses of the Fund.

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.

Swaps Risk. Swaps are subject to tracking risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Over the counter swaps are subject to counterparty default. Leverage inherent in derivatives will tend to magnify the Fund’s losses. The costs of investing in swaps will be indirectly paid by the Fund.

Tax Risk. By investing in commodities indirectly through the Subsidiary, the Fund will obtain exposure to the commodities markets within the federal tax requirements that apply to the Fund. However, because the Subsidiary is a controlled foreign corporation, any income received from its investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains.

Turnover Risk. The Fund may have a high turnover of the securities held in its portfolio.

Increased portfolio turnover causes the Fund to incur higher brokerage costs, which may adversely affect the Fund’s performance and may produce increased taxable distributions.

Underlying Fund Risk. Because the Fund may invest in other investment companies, the value of your investment will fluctuate in response to the performance of the underlying funds. Investing in underlying funds involves certain additional expenses and certain tax results that would not arise if you invested directly in the underlying funds. By investing in underlying funds, you will bear not only your proportionate share of the Fund’s expenses (including operating costs and investment advisory and administrative fees), but also, indirectly, similar expenses and charges of the underlying funds, including any contingent deferred sales charges and redemption charges. Finally, you may incur increased tax liabilities by investing in the Fund rather than directly in the underlying funds. Each underlying fund is subject to specific risks, depending on the nature of its investment strategy, including liquidity risk and default risk on the assets held by the underlying fund.

U.S. Government Obligations Risk. The Fund may invest in U.S. government or agency obligations. Securities issued or guaranteed by federal agencies and U.S. government sponsored entities may or may not be backed by the full faith and credit of the U.S. government.

Wholly-Owned Subsidiary Risk. By investing in the Subsidiary, the Fund is indirectly exposed to the commodities risks associated with the Subsidiary’s investments in commodity-related instruments. Shareholders of the Fund are indirectly subject to the principal risks of the Subsidiary by virtue of the Fund’s investment in the Subsidiary. There can be no assurance that the Subsidiary’s investments will contribute to the Fund’s returns. The Subsidiary is not registered under the Investment Company Act of 1940 Act, as amended (the “1940 Act”), and 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 operate as described in this Prospectus and could adversely affect the Fund, such as by reducing the Fund’s investment returns. The Fund and the Subsidiary are “commodity pools” under the U.S. Commodity Exchange Act, as amended, and the Advisor is a “commodity pool operator” registered with and regulated by the Commodity Futures Trading Commission (“CFTC”). As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations apply with respect to the Fund and the Subsidiary and subject each to CFTC penalties if reporting was found to be deficient.

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows performance of the Fund’s Class I shares for each of the last ten full calendar years. Although Class A, C and Class C-1 shares have similar annual returns to Class I shares because the classes are invested in the same portfolio of securities, the returns for Class A, Class C and Class C-1 shares are different from Class I shares because Class A, Class C and Class C-1 shares have different expenses than Class I shares. The performance table shows how the average annual total returns for Class I, Class A, Class C and Class C-1 shares compared over time with those of a broad-based market index, a supplemental index, as well as a hedge fund index comprised of funds with similar objectives as the Fund and a treasury bill index.

How the Fund has performed in the past (before and after taxes) is not necessarily an indication of how it will perform in the future.
