1 The 1.00% maximum deferred sales charge may be assessed in the case of investments at or above the $1 million breakpoint (where you do not pay an initial sales charge) on shares redeemed within two years of purchase.

2 The Fund's investment advisor, Catalyst Capital Advisors LLC (the "Advisor"), has contractually agreed to waive advisory fees and/or reimburse expenses of the Fund to the extent necessary to limit total annual fund operating expenses (excluding brokerage costs; borrowing costs, such as (a) interest and (b) dividends on securities sold short; taxes; underlying fund expenses; and extraordinary expenses, such as regulatory inquiry and litigation expenses) at 1.53%, 2.28% and 1.28% for Class A shares, Class C shares and Class I shares, respectively, through October 31, 2025. This agreement may only be terminated by the Board of Trustees on 60 days' written notice to the Advisor, by the Advisor with the consent of the Board of Trustees, or upon the termination of the investment advisory agreement between the Trust and the Advisor. Fee waivers and expense reimbursements are subject to possible recoupment by the advisor from the Fund in future years on a rolling three-year basis (within the three years after the fees have been waived or reimbursed) so long as such recoupment does not cause the Fund's expense ratio (after the repayment is taken into account) to exceed the lesser of: (i) the Fund's expense limitation at the time such expenses were waived and (ii) the Fund's current expense limitation at the time of recoupment.

Example: 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 in place through its expiration period, October 31, 2025, 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:

YEAR Class A Class C Class I
1 $722 $231 $130
3 $1,171 $864 $552
5 $1,645 $1,522 $999
10 $2,950 $3,285 $2,240

Portfolio Turnover: The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover 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, 2024 was 183% of the average value of its portfolio.

Principal Investment Strategies:

The Fund seeks to achieve its investment objective by combining a portfolio of common stock (the "Common Stock Component") with an overlay component that provides exposure to quantitative investment strategies (the "Overlay Component").

Common Stock Component

The Common Stock Component invests in common stocks of U.S. companies, including real estate investment trusts ("REITs"), and American Depositary Receipts ("ADRs"). The Fund purchases positions in stocks that are experiencing insider buying by corporate executives, directors, large shareholders or activist shareholders. The Fund may invest in companies of any market capitalization, including smaller-sized companies, but intends to emphasize larger capitalization stocks.

The Advisor uses public information that is filed with the Securities and Exchange Commission ("SEC") on corporate insider and large shareholder buying and selling activity for its investment decisions. The Advisor's research and quantitative back-testing of insider trading data over long periods of time has resulted in the development of a proprietary method of analyzing insider trading activity that it believes can provide long-term capital appreciation. The underlying thesis is that corporate insiders and large or activist shareholders know more about the prospects of the company than anybody else.

The Advisor's investment process focuses on insider identities (position in the company), motivations, insider trading trends, trading volumes, firm size and other factors to select stocks for the portfolio. Stocks are sold when the relevant insider trading trends reverse or when portfolio

3

positions achieve or no longer provide the targeted risk adjusted return. The Fund actively trades its portfolio investments, which may lead to higher transaction costs that may affect the Fund's performance.

Overlay Component

The Overlay Component is designed to provide the Fund with exposure to various asset classes and strategies that have historically demonstrated the potential to produce attractive total return over the long term with low to moderate correlation to equities and bonds. The Overlay Component generally seeks to gain this exposure by investing in one or more structured notes and/or one or more non-exchange-traded total return swap contracts.

The Overlay Component pursues an absolute return, multi-risk premia strategy (i.e., a multi-risk factor strategy) that attempts to capture various sources of systematic risk premia in the capital markets. Risk premia refers to sources of return derived by accepting risks beyond those inherent in traditional broad market exposures, such as long-only broad-market equity and bond indexes. Risk premia are considered the building blocks of many variable (i.e., non-linear) and hedged investment strategies. Risk premia strategies use publicly traded instruments and tend to have lower correlation to equities and bonds as well as to one another.

The Overlay Component's multi-risk premia strategy provides exposure to a blend of Carry, Momentum, Value and Volatility Risk Premia across equity, commodity, foreign exchange and fixed income markets and invests in futures and options on equity indices, commodities, government bonds and non-government bonds, interest rates and currency forwards.

· Carry Risk Premia: Captures the tendency for higher yielding assets to outperform lower yielding assets over time. Typical Carry Risk Premia strategies include having long, high carry assets and short, low carry assets. An example is to synthetically buy high yielding currency forward contracts and sell low yielding currency forward contracts.
· Momentum Risk Premia: Captures the tendency for assets that have performed well in the recent past to continue to perform well, and assets that have performed poorly in the recent past to continue to perform poorly. Typical Momentum Risk Premia strategies include being long historically high performing assets and being short historically low performing assets. An example is to synthetically buy positive trending futures and sell negatively trending futures across multiple asset classes.
· Volatility Risk Premia: Captures the behavioral tendency of markets to over-exaggerate implied or expected volatility. Typical Volatility Risk Premia strategies include being short an asset's expected end-of-day price standard deviation (implied volatility) and being long an asset's realized end-of-day price standard deviation (realized volatility) over a specified period. An example would be writing ultra short put options on the S&P 500 Index with an intra-day delta hedge.
4
· Value Risk Premia: Captures the behavioral tendency of asset prices to mean revert to fair value anchors. Typical Value Risk Premia strategies include short term mean-reversion strategies that use price and fundamental indicators to open short positions in "overbought" assets and open long positions in "oversold" assets. An example would be to open short positions in overbought currency pairs and open long positions on oversold currency pairs.

The Overlay Component's allocations across these risk premia strategies are made at the discretion of the Advisor with the intent to best complement the Common Stock Component.

Investments in Subsidiary

The Advisor executes a portion of the Fund's strategy by investing up to 25% of the Fund's total assets in the Subsidiary, a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands. The Subsidiary invests the majority of its assets in structured notes and total return swap contracts. The Subsidiary is subject to the same investment restrictions as the Fund, when viewed on a consolidated basis.

Principal Risks of Investing in the Fund:

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 the value of the Fund and your investment.

ADRs Risk. ADRs, which are typically issued by a bank, are certificates that evidence ownership of shares of a foreign company and are alternatives to purchasing foreign securities directly in their national markets and currencies. ADRs are subject to the same risks as direct investment in foreign companies and involve risks that are not found in investments in U.S. companies.

Changing Fixed Income Market Conditions Risk. Any future interest rate increases could cause the value of any fund that invests in fixed income securities to decrease to the extent that it invests in fixed income 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.

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, geologic and environmental factors as well as changes in government regulation such as tariffs, embargoes or burdensome production rules and restrictions.

Counterparty Risk. Counterparty risk is the risk that 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.

5

Credit Risk. Credit risk is the risk that an issuer of a security will fail to pay principal and interest in a timely manner, reducing the Fund's total return. The Fund may invest in high-yield, high-risk securities, commonly called "junk bonds," that are not investment grade and are generally considered speculative because they present a greater risk of loss, including default, than higher quality debt securities. Credit risk may be substantial for the Fund.

Currency Risk. Currency risk is the risk that fluctuations in exchange rates will 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. Derivative transactions in foreign currencies (such as futures, forwards, options, and swaps) are also subject to currency risk. 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 risk, counterparty credit risk and short sale risk. Market risk results from the price movement of foreign currency values in response to shifting market supply and demand. Since exchange rate changes can readily move in one direction, a currency position carried overnight or over a number of days may involve greater risk than one carried a few minutes or hours. Interest rate risk arises whenever a country changes its stated interest rate target associated with its currency. Country risk arises because virtually every country has interfered with international transactions in its currency. Interference has taken the form of regulation of the local exchange market, restrictions on foreign investment by residents or limits on inflows of investment funds from abroad. Restrictions on the exchange market or on international transactions are intended to affect the level or movement of the exchange rate. This risk could include the country issuing a new currency, effectively making the "old" currency worthless. The Fund may also take short positions, through derivatives, if the Advisor believes the value of a currency is likely to depreciate in value.

Derivatives Risk. Even a small investment in derivatives (including the Fund's exposure to futures, forwards and options) may give rise to leverage risk (which can increase volatility and magnify the Fund's potential for loss), 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. A heightened risk is posed by rising interest rates to a fund whose portfolios include longer-term fixed income securities. Effective duration estimates price changes for relatively small changes in rates.

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.

6

Fixed-Income Risk. When the Fund invests in fixed income securities, the value of your investment in the Fund will fluctuate with changes in interest rates. Typically, a rise 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. 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.

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, risks of investing in foreign developed countries. Foreign companies are generally not subject to the same regulatory requirements of U.S. companies thereby resulting in less publicly available information about these companies.

Forwards 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 forward or futures contract; (b) possible lack of a liquid secondary market for a forward or futures contract and the resulting inability to close a forward or 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.

7

Income Risk. Income risk is the risk that the income from the Fund's portfolio will decline because of falling market interest rates. This can result when the Fund invests the proceeds from new share sales, or from matured or called bonds, at market interest rates that are below the portfolio's current earnings rate.

Interest Rate Risk. Interest rate risk is the risk that bond prices overall, including the prices of securities held by the Fund, will 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. For example, if interest rates go up by 1.0%, the price of a 4% coupon bond will decrease by approximately 1.0% for a bond with 1 year to maturity and approximately 4.4% for a bond with 5 years to maturity. Rising interest rates pose a heightened risk to the Fund's longer-term fixed income securities.

Large Capitalization Company Risk. The Fund may invest in large capitalization companies. The securities of such companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and may be unable to attain high growth rates during periods of economic expansion.

Leverage Risk. Using derivatives 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. Some investments held by the Fund may be difficult to sell, or illiquid, particularly during times of market turmoil. Illiquid investments may also be difficult to value. If the Fund is forced to sell an illiquid asset to meet redemption requests or other cash needs, the Fund may be forced to sell at a loss.

Management Risk. The portfolio managers' judgments about the attractiveness, value and potential appreciation of particular stocks 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 and political events affect the securities markets.

8

Medium (Mid) Capitalization Company Risk. The earnings and prospects of mid-capitalization companies are more volatile than larger companies, they may experience higher failure rates than larger companies and normally have a lower trading volume than larger companies, which may tend to make their market price fall more disproportionately than larger companies in response to selling pressures.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the swap 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 swap'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 Fund's use of options. As the buyer of a call option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not rise above the strike price, which means the option will expire worthless. As the buyer of a put option, the Fund risks losing the entire premium invested in the option if the underlying reference instrument does not fall below the strike price, which means the option will expire worthless. Conversely, as a seller (writer) of a call option or put option, the Fund will lose money if the value of the underlying reference instrument rises above (written call option) or falls below (written put option) the respective option's strike price. The Fund's losses are potentially large in a written put transaction and potentially unlimited in an unhedged written call transaction.

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).

9

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 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. Subprime mortgages are riskier and potentially less liquid than other mortgage-backed securities.

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.

Sector Exposure Risk. Sector exposure risk is the possibility that securities within the same sector will decline in price due to sector-specific market or economic developments. If the Fund invests more heavily in a particular sector, the value of its shares may be especially sensitive to factors and economic risks that specifically affect that sector.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns.

Financials Sector Risk. Performance of companies in the financials sector may be adversely impacted by many factors, including, among others, government regulations, economic conditions, credit rating downgrades, changes in interest rates, and decreased liquidity in credit markets.

Healthcare Sector Risk. Companies in the healthcare sector may be heavily dependent on clinical trials with uncertain outcomes and decisions made by the governments and regulatory authorities. Further, these companies are dependent on patent protection, and the expiration of patents may adversely affect the profitability of the companies. Additionally, the profitability of some healthcare companies may be dependent on a relatively limited number of products, and their products can become obsolete due to sector innovation, changes in technologies or other market developments.

Technology Sector Risk. Technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face obsolescence due to rapid technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel.

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

10

Small Capitalization Company Risk. To the extent the Fund invests in the stocks of smaller-sized companies, the Fund may be subject to additional risks, including the risk that earnings and prospects of these companies are more volatile than larger companies.

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 events that affect the industry. In addition, there may be a lag between a change in the value of the underlying reference asset and the value of the structured note. Structured notes may also be subject to counterparty risk. The Fund may also be exposed to increased transaction costs when it seeks to sell such notes in the secondary market.

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 Rate Risk. The Fund may have portfolio turnover rates significantly in excess of 100%. 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.

U.S. Government Obligations Risk. Securities issued or guaranteed by federal agencies or authorities and U.S. government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. government. The Fund may be subject to such risk to the extent it invests in securities issued or guaranteed by federal agencies or authorities and U.S. government sponsored instrumentalities or enterprises.

Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value of short periods of time. This may cause the Fund's net asset value per share to experience significant increases or declines in value over short periods of time, however, all investments long- or short-term are subject to risk of loss.

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 (the "1940 Act"), and is not subject to

11

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, 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.

Performance:

The bar chart and accompanying table shown below provide an indication of the risks of investing in the Fund. The bar chart shows the performance 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 returns of the Class A, C, and 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. 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 is available at no cost by calling 1-866-447-4228 and on the Fund's website at www.CatalystMF.com.

Annual Total Returns

During the period shown in the bar chart, the highest return for a quarter was 18.04% (quarter ended March 31, 2019), and the lowest return for a quarter was (27.60)% (quarter ended June 30, 2022). The Fund's Class A shares year-to-date return as of September 30, 2024 was 24.81%.
