FUND SUMMARY – Return Stacked^® Balanced Allocation & Systematic Macro FUND

Investment Objective: The Fund’s investment objective is to seek long-term capital appreciation.

Fees and Expenses of the Fund: 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 sections of the Fund’s Prospectus entitled How to Buy Shares on page 141 and Appendix A - Intermediary-Specific Sales Charge Reductions and Waivers, and in the sections of the Fund’s Statement of Additional Information (“SAI”) entitled Waivers and Reductions of Up-Front Sales Charge on Class A Shares on page 90.

this agreement for a period of three years from the date the fees were waived or expenses paid, if the recoupment can be achieved without causing the expense ratio of the share class (after the recoupment is taken into account) to exceed (i) the expense limit in effect at the time the fees were waived or expenses paid, or (ii) the expense limit in place at the time of the 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 shows the operating expenses you would incur as a shareholder if you invested $10,000 in the Fund over the time periods shown and then redeem (or you hold, as applicable)all your shares at the end of those periods. The Example also assumes that the average annual return was 5%, the Fund’s operating expenses remain the same, and the expense reduction/reimbursement remains in place for the contractual period only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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. During the most recent fiscal year, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio.

Principal Investment Strategies

The Fund is an actively-managed mutual fund that seeks to achieve its investment objective by investing in two complementary strategies: a Balanced Allocation Strategy and a Systematic Macro Strategy. The Fund uses derivative contracts to "stack" the total return of holdings in the Fund’s Balanced Allocation Strategy together with the returns of the Fund’s Systematic Macro Strategy. Essentially, one dollar invested in the Fund provides approximately one dollar of exposure to the Fund’s Balanced Allocation Strategy and approximately one dollar of exposure to its Systematic Macro Strategy. Therefore, the returns of the Systematic Macro Strategy are effectively stacked on top of the returns of the Balanced Allocation Strategy.

Under normal circumstances, the Fund will target a 100% exposure to the Balanced Allocation Strategy and 100% exposure to the Systematic Macro Strategy. Each Strategy is described below. Notional value is the total underlying amount of a derivatives trade. Leverage allows an investor (like the Fund) to use a small amount of money to gain exposure to a larger (and potentially, a much larger) amount. So, notional value reflects the total value of a trade, not the cost (or market value) of taking the trade. Through the Fund’s use of futures in both its Balanced Allocation Strategy and Systematic Macro Strategy (described below), the Fund provides leveraged exposure to a combination of assets held in the Balanced Allocation Strategy (U.S. equity and U.S. fixed income) and the Systematic Macro Strategy (equities, fixed income, currencies, and commodities).Further, the Fund (and the Subsidiary) will hold U.S. Treasury bills and cash equivalents as collateral for the futures contracts as well as to generate income.

Balanced Allocation Strategy:

The Fund’s Balanced Allocation Strategy aims to provide exposure to a target mix of approximately 50% U.S. equities and 50% U.S. bonds (100% total) with the objective of long-term capital appreciation. To achieve this, the Fund will invest in a combination of U.S. common stock, U.S. treasury securities,

exchange-traded funds (“ETFs”), and futures contracts. Newfound Research LLC (“Newfound”) serves as the investment sub-adviser to the Balanced Allocation Strategy.

U.S Equity Strategy:

The U.S. Equity Strategy seeks to capture the total return of large capitalization U.S. equity markets with the objective of long-term capital appreciation. The Fund will gain exposure to large capitalization U.S. equity markets through investment in broad-based U.S. large capitalization ETFs and/or U.S. equity index futures contracts. The Fund may also implement the U.S. Equity Strategy by investing directly in the common stock of U.S. large capitalization companies. The Fund defines large capitalization companies as those companies with market capitalizations of $8 billion or greater.

U.S. Bond Strategy:

The U.S. Bond Strategy seeks to capture the total return of the broad, investment grade, U.S. fixed income market with the objective of long-term capital appreciation. To do so, the Fund will invest in ETFs that provide broad exposure to investment grade U.S. corporate and government bonds and/or U.S. Treasury futures contracts, and will invest in such ETFs without any constraints as to maturity. The Fund will also invest in futures contracts on U.S. Treasuries with maturities ranging from two to 30 years, with a target duration of two to eight years.

The Fund may also implement the U.S. Bond Strategy by investing directly in U.S. Treasury bills, notes, and bonds across the yield curve. The U.S. Treasury securities held by the Fund will have a target duration of two to eight years.

Systematic Macro Strategy:

The Fund provides exposure to major global asset classes, including, equities, bonds, currencies, and commodities. To gain access to these asset classes, the Fund will invest in futures (including commodity futures, index futures, equity futures, bond futures and interest rate futures), currency forwards, options and swaps (including commodity swaps, swaps on commodity futures, equity swaps, swaps on index futures, total return swaps and interest rate swaps), either by investing directly in the instruments or, indirectly, through its Subsidiary (as described below). Investments by the Fund may be made in domestic and foreign markets, including emerging markets.

The Fund’s futures trading advisor, ReSolve Asset Management SEZC (Cayman) (the “Futures Trading Advisor” or “ReSolve Global”), uses a proprietary methodology to create a portfolio of securities with exposures to a number of characteristics, including, but not limited to: total-return momentum, trends, seasonal patterns, carry measures, mean reversion and others, while simultaneously maximizing diversification based on changing estimates of volatility and correlations across global asset classes.

approach, the Futures Trading Advisor seeks to capture opportunities across various asset classes, including equities, bonds, currencies, and commodities.

The Fund will take long or short positions in asset classes, such as equity index and fixed income asset classes, commodities, currencies and volatility indexes. Fund holdings and weights are regularly adjusted in response to material changes in world markets.

The Futures Trading Advisor will utilize its proprietary investment models to determine asset allocations based on multi-factor quantitative market information and account for the opportunity to reduce portfolio volatility through diversification. However, the long-term expected volatility of the Fund, in totality, will be greater than the volatility of either the Balanced Allocation Strategy or Systematic Macro Strategy measured in isolation. The investment models analyze these factors over a broad time spectrum, which may range from several days to multiple years. The Futures Trading Advisor analyzes a number of additional factors in determining how the asset classes are allocated in the portfolio, including, but not limited to: intermediate term (1-18 months) profitability of an asset class or market, liquidity of a particular market, desired diversification among markets and asset classes, transaction costs, exchange regulations, and depth of market. The allocations are reviewed daily, although changes may occur less frequently.

Under normal circumstances, the Fund’s aggregate notional exposure to the Systematic Macro Strategy will be approximately 100% of the Fund’s net assets, creating overlay exposure through leverage to a globally diversified portfolio of futures contracts. For example, if the Fund has $100 in assets, the Fund expects to achieve $100 of exposure to the Balanced Allocation Strategy and $100 of exposure to the Systematic Macro Strategy from the leverage created by the futures contracts. This is akin to investing $100 in a combination of U.S. Equity and/or U.S. Fixed Income securities or ETFs, borrowing $100, and putting the borrowed $100 in a systematic macro fund. The Fund’s use of leverage, represented by the borrowed $100

in the example, could amplify the effects of market volatility on Fund performance when compared to investing directly in the same portfolio.

The Fund expects to invest up to approximately 50% of its net assets in U.S. Treasury bills, money market funds, cash, and cash equivalents (e.g., high quality commercial paper and similar instruments that are rated investment grade or, if unrated, of comparable quality, as the Adviser or Futures Trading Adviser determines), that provide liquidity, serve as margin or collateralize the Fund’s investments in derivative contracts for the Systematic Macro Strategy. Combined with the Balanced Allocation Strategy, the Fund may invest up to 100% of the Fund’s net assets in U.S. Treasury bills, money market funds, cash, and cash equivalents.

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 Fund executes a portion of its 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 commodity futures contracts and other derivative contracts, subject to the same investment restrictions as the Fund, when viewed on a consolidated basis. The Subsidiary is subject to the same investment restrictions as the Fund, when viewed on a consolidated basis. The Subsidiary is RDMF Fund Limited, a Cayman Islands company. The Subsidiary is advised by the Fund’s Advisor, Futures Trading Advisor and ReSolve Asset Management Inc., the Fund’s investment sub-advisor to the Systematic Macro Strategy. The Fund actively trades its portfolio investments, which may lead to higher transaction costs that may affect the Fund’s performance.

Principal Investment Risks

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

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.

Cash or Cash Equivalents Risk. At times, the Fund may have significant investments in cash or cash equivalents. When a substantial portion of a portfolio is held in cash or cash equivalents, there is the risk that the value of the cash account, including interest, will not keep pace with inflation, thus reducing purchasing power over time. Additionally, in rising markets, holding cash or cash equivalents may adversely affect the Fund’s performance and the Fund may not achieve its investment objective.

Changing Fixed Income Market Conditions Risk. Interest rate fluctuations 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 investments of the Fund and/or the underlying ETFs the Fund invests in (each, an “Underlying Fund”), which could cause the value of the Fund’s and/or Underlying Fund’s investments and share price to decline.

Commodity Risk. Investing in the commodities markets (directly or indirectly) 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.

Commodity Tax Risk. The tax treatment of commodity-linked derivative instruments may be adversely affected by changes in legislation, regulations or other legally binding authority. If, as a result of any such adverse action, the income of the Fund from certain commodity-linked derivatives was treated as non-qualifying income, the Fund might fail to qualify as a regulated investment company and be subject to federal income tax at the Fund level. The Fund intends to invest in commodity-linked derivatives indirectly through the Subsidiary. Any income received from the Subsidiaries investments will be passed through to the Fund as ordinary income, which may be taxed at less favorable rates than capital gains. Should the Internal Revenue Service issue further guidance, or Congress enact legislation, that adversely affects the tax treatment of the Fund’s use of commodity-linked derivatives or the Subsidiary (which guidance might be applied to the Fund retroactively), it could, among other consequences, limit the Fund’s ability to pursue its investment strategy.

Correlation Risk. There is no guarantee that the Fund’s historical relationship and correlation to equity direction or volatility will continue. As a result, there is no guarantee that the Fund will achieve lower volatility than the Index and/or better performance than the Index as a result of its blend of strategies. Correlation and covariance are factors that impact the Fund’s calculation of risk. There is also no guarantee that these factors will accurately predict future risk. Just as past performance is not necessarily indicative of future performance, past correlation is not necessarily indicative of future correlation.

Counterparty Risk. The value of the Fund’s investments may be adversely affected if an issuer’s securities experience a credit downgrade; an issuer or guarantor of an investment held by the Fund fails to pay an obligation on a timely basis, otherwise defaults or is perceived by other investors to be less creditworthy; or a counterparty to a derivatives or other transaction with the Fund files for bankruptcy, becomes insolvent, or otherwise becomes unable or unwilling to honor its obligation to the Fund and therefore delays or impairs the Fund’s ability to recover its deposits with such counterparty.

Currency Risk. Currency trading risks, including through futures contracts, include market risk, credit risk and country risk. Market risk results from adverse changes in exchange rates in the currencies the Fund is long or short. Credit risk results because a currency-trade counterparty may default. Country risk arises because a government may interfere with transactions in its currency.

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 (see “Counterparty Risk” above); (ii) risk of mispricing or improper valuation; and (iii) the risk that changes in the value of the derivative may not correlate perfectly with the underlying reference asset. Derivatives can also create leverage risk because they do not require payment up front equal to the economic exposure created by holding a position in the derivative. As a result, an adverse change in the value of the underlying asset could result in the Fund sustaining a loss that is substantially greater than the amount invested in the derivative or the anticipated value of the underlying asset, which may make the Fund’s returns more volatile and increase the risk of loss. Derivative instruments may be less liquid than more traditional

investments and the Fund may be unable to sell or close out its derivative positions at a desirable time or price. This risk may be more acute under adverse market conditions, during which the Fund may be most in need of liquidating its derivative positions. Derivatives may also be less tax efficient and subject to changing government regulation that could impact the Fund’s ability to use certain derivatives or their cost. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the risk of the underlying asset being hedged. Derivative prices are highly volatile and may fluctuate substantially during a short period of time. Such prices are influenced by numerous factors that affect the markets, including, but not limited to: changing supply and demand relationships; government programs and policies; national and international political and economic events, changes in interest rates, inflation and deflation and changes in supply and demand relationships. Derivatives strategies may not always be successful, and their successful use will depend on the portfolio managers’ ability to accurately forecast movements in the market relating to the underlying asset.

Foreign Currency Forward Contract Risk. Foreign currency forward contracts are a type of derivative contract whereby a Fund may agree to buy or sell a country's or region's currency at a specific price on a specific date, usually 30, 60, or 90 days in the future. These contracts are subject to the risk of political and economic factors applicable to the countries issuing the underlying currencies and may fall in value due to foreign market downswings or foreign currency value fluctuations. Forward foreign currency contracts are individually negotiated and privately traded so they are dependent upon the creditworthiness of the counterparty and subject to counterparty 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. The Fund's investment or hedging strategies may not achieve their objective.

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 Risk. Investments in futures contracts involve leverage, which means a small percentage of assets invested in futures can have a disproportionately large impact on the Fund. This risk could cause the Fund to lose more than the principal amount invested. In addition, futures contracts may become mispriced or improperly valued relative to the Futures Trading Advisor’s expectations and may not produce the desired investment results. Additionally, changes in the value of futures contracts may not track or correlate perfectly with the underlying reference asset because of temporary, or even long-term, supply and demand imbalances and because futures do not pay dividends.

Leverage and Volatility Risk. Derivative contracts ordinarily have leverage inherent in their terms, meaning that the Fund can obtain significant investment exposure in return for meeting a relatively small margin or other investment requirement. The low margin deposits normally required in trading derivatives permit a high degree of leverage. Accordingly, a relatively small price movement may result in an immediate and substantial loss to the Fund, potentially in excess of the amounts invested or borrowed. The use of leverage may also cause the Fund to liquidate portfolio positions when it would not be advantageous to do so in order to satisfy its obligations or to meet collateral segregation

requirements. The use of leveraged derivatives can magnify a Fund’s potential for gain or loss and, therefore, amplify the effects of market volatility on the Fund’s share price.

Liquidity Risk. It is possible that particular derivative investments might be difficult to purchase or sell, possibly preventing a Fund from executing positions at an advantageous time or price, or possibly requiring it to dispose of other investments at unfavorable times or prices in order to satisfy its obligations.

Options Market Risk. Markets for options and options on futures may not always operate on a fair and orderly basis. At times, prices for options and options on futures 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 a 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. Generally, options may not be an effective hedge because they may have imperfect correlation to the value of a Fund's portfolio securities. Additionally, the underlying reference instrument on which the option is based may have imperfect correlation to the value of a Fund's portfolio securities. As the buyer of a call option, a 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, a 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. Additionally, purchased options may decline in value due to changes in price of the underlying reference instrument, passage of time and changes in volatility. As a seller (writer) of a put option, a Fund will lose money if the value of the underlying reference instrument falls below the strike price. As a seller (writer) of a call option, a Fund will lose money if the value of the underlying reference instrument rises above the strike price. A Fund's losses are potentially large in a written put transaction and potentially unlimited in a written call transaction. Option premiums received from the written put and call options may offset losses due to the aforementioned adverse changes in value of the underlying reference instrument, but the Fund will continue to bear the risk that it will lose money if the value of the underlying reference instrument adversely increases above or decreases below the Fund’s strike price, as applicable. 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. Because option premiums paid or received by a Fund are small in relation to the market value of the investments underlying the options, buying and selling put and call options can be more speculative than investing directly in securities.

Swaps Risk. A Fund may use swaps to enhance returns and manage risk. A Fund's use of swaps involves risks different from, or possibly greater than, the risks associated with investing directly in securities and other traditional investments and exposes the Fund to the risks associated with derivative instruments described above. In a standard “swap” transaction, two parties agree to exchange the returns, differentials in rates of return or some other amount earned or realized on the “notional amount” of predetermined investments or instruments, which may be adjusted for an interest factor. Swaps can involve greater risks than direct investment in securities, because swaps may be leveraged and subject to counterparty risk (e.g., the risk of a counterparty’s defaulting on the

obligation or bankruptcy), credit risk and pricing risk (i.e., swaps may be difficult to value). Swaps are also subject to non-correlation risk because they may not be perfect substitutes for the instruments they are intended to hedge or replace. Swaps may also be considered illiquid. It may not be possible for the Fund to liquidate a swap position at an advantageous time or price, which may result in significant losses.

Total Return Swap Risk. A total return swap is a contract in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities, or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to the Fund's portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. The primary risks associated with total returns swaps are credit risk (if the counterparty fails to meet its obligations) and liquidity risk (if there is no liquid market for the agreement or unfavorable changes occur to the underlying asset).

Emerging Market Risk. Emerging market countries may have relatively unstable governments, weaker economies, and less-developed legal systems with fewer security holder rights. Securities law and the enforcement of systems of taxation in many emerging market countries may change quickly and unpredictably, and the ability to bring and enforce actions, or to obtain information needed to pursue or enforce such actions, may be limited. Companies in emerging market countries generally may be subject to less stringent regulatory, disclosure, financial reporting, accounting, auditing and recordkeeping standards than companies in more developed countries. As a result, information, including financial information, about such companies may be less available and reliable, which can impede the Fund’s ability to evaluate such companies. Emerging markets usually are subject to greater market volatility, political, social, and economic instability, uncertainty regarding the existence of trading markets, and more governmental limitations on foreign investment than are more developed markets. 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 and the prices of such securities tend to be more volatile than the securities of issuers located in developed markets. Investments in emerging markets securities may be subject to additional transaction costs, delays in settlement procedures, unexpected market closures, and lack of timely information.

Equity Securities Risk. The price of equity securities in the Fund’s portfolio will fluctuate based on actual or perceived changes in a company’s financial condition and on market and economic conditions. 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. The value of the Fund’s investments in fixed income securities, whether held directly or through futures contracts, 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), extension risk (an issuer may exercise its right to repay principal on a fixed rate obligation held by the Fund later than expected), 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 Commodity Futures Trading Commission (“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. Investments in foreign securities tend to be more volatile and less liquid than investments in U.S. securities because, among other things, they involve risks relating to political, social and economic developments abroad, including economic sanctions, as well as risks resulting from differences between the regulations and reporting standards and practices to which U.S. and foreign issuers are subject. Investing in foreign securities includes trading related risks (e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S., and foreign securities may be subject to foreign governmental restrictions such as exchange controls). All of the risks of investing in foreign securities are typically increased by investing in emerging market countries. Securities denominated in foreign currencies may be adversely affected by changes in currency rates and by substantial currency conversion costs.

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.

Large Capitalization Stock Risk. Investments in larger, more established companies are subject to the risk that larger companies are sometimes unable to attain the high growth rates of successful, smaller companies, especially during extended periods of economic expansion. Large capitalization companies may be less able than smaller capitalization companies to adapt to changing market conditions. Larger, more established companies may be unable to respond quickly to new competitive challenges, such as changes in consumer tastes or innovative smaller competitors, potentially resulting in lower markets for their common stock. During different market cycles, the performance of large capitalization companies has trailed the overall performance of the broader securities markets.

Leverage Risk. The use of leverage by the Fund, such as through the use of derivatives, will cause the Fund to incur additional expenses and magnify the Fund's gains or losses. Relatively small market movements may result in large changes in the value of a leveraged derivatives position. Leveraging also may require that the Fund liquidate portfolio securities when it may not be advantageous to do so to satisfy its obligations. Leveraging may expose the Fund to losses in excess of the amounts invested or borrowed.

Management Risk. The investment strategies and models employed by the Sub-Advisors and/or the Futures Trading Advisor in selecting investments and asset allocations for the Fund may not result in an increase in the value of your investment or in overall performance equal to other similar investment vehicles having similar investment strategies. In addition, the Sub-Advisors’ and/or the Futures Trading Advisor’s judgment about the attractiveness, value and potential appreciation of particular investments may prove to be incorrect and there is no guarantee that the Sub-Advisors’

and/or the Futures Trading Advisor’s determinations will produce the desired result. The measures that the Advisor, Sub-Advisors or portfolio manager use to monitor and manage the risks of the Fund may not accomplish the intended results and the Fund may experience losses significantly greater than expected.

Market Risk. The value of securities in the Fund’s portfolio will fluctuate and, as a result, the Fund’s share price may decline suddenly or over a sustained period of time. Overall market risks may also affect the value of the Fund. Factors such as economic growth and market conditions, trading and tariff arrangements, interest rate levels and political events affect the securities markets.

Model and Data Risk. Like all quantitative analysis, the investment models utilized by the Sub-Advisor and the Futures Trading 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 is usually based on data supplied by third parties, the success of the Sub-Advisor’s or the Futures Trading 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.

Regulatory Risk. Changes in the laws or regulations of the United States, Cayman Islands, 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. 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 CFTC. As a result, additional CFTC-mandated disclosure, reporting and recordkeeping obligations will apply with respect to the Fund. Compliance with these regulatory requirements could increase the Fund’s expenses.

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, whether held directly or through futures contracts.

Short Position Risk. The Fund will incur a loss as a result of a short position, in securities or futures, if the price of the short position instrument increases in value between the date of the short position sale and the date on which an offsetting position is purchased. Losses due to short sales are potentially unlimited. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the Futures Trading Advisor’s ability to accurately anticipate the future value of a security or instrument.

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 a wholly-owned and controlled subsidiary of the Fund organized under the laws of the Cayman Islands (a “Subsidiary), the Fund would intend 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 would be passed through to the Fund as ordinary income, which may be taxed at less

favorable rates than capital gains.  The Subsidiary would declare and distribute 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.

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.

U.S. Agency Securities 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.

Underlying Fund Risk. Other investment companies including mutual funds, ETFs and closed-end funds (“Underlying Funds”) in which a Fund invests are subject to investment advisory and other expenses, which will be indirectly paid by the Fund. As a result, the cost of investing in the Fund will be higher than the cost of investing directly in the Underlying Funds and may be higher than other mutual funds that invest directly in stocks and bonds. In addition, when a Fund invests in Underlying Funds, there is a risk that the investment advisers of those Underlying Funds may make investment decisions that are detrimental to the performance of the Fund. Each of the Underlying Funds is subject to its own specific risks. Additional risks of investing in the Underlying Funds are described below:

ETF Risk. Like a 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 or be maintained; and (iii) market trading in the ETF may be halted under certain circumstances. Because the Fund may invest its assets in ETFs that have their own fees and expenses in addition to those charged directly by the Fund, the Fund may bear higher expenses than a fund that invests directly in individual securities.

ETF Tracking Risk. Index-based or “passive” ETFs, which seek to track the performance of an underlying index, will not be able to replicate exactly the performance of the indices they track because the total return generated by the securities will be reduced by transaction costs incurred in adjusting the actual balance of the securities. In addition, passive ETFs will incur expenses not incurred by their applicable indices. Certain securities comprising the indices tracked by the passive ETFs may, from time to time, temporarily be unavailable, which may further impede the ETFs’ ability to track their applicable indices.

Volatility Risk. The Fund may have investments that appreciate or decrease significantly in value over 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. 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 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.

For more information, please see the section of the Fund’s Prospectus entitled “Additional Information Regarding the Fund’s Principal Investment Strategies and Related Risks.” 

Performance: The Fund acquired all of the assets and liabilities of Chesapeake Fund, LLC (the “Predecessor Fund”) in a tax-free reorganization on September 30, 2016 (the “Reorganization”). In connection with the Reorganization, shares of the Predecessor Fund were exchanged for Institutional shares of the Fund. At the time of the reorganization, 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. However, the Predecessor Fund was not registered under the 1940 Act and, therefore, was not subject to certain investment restrictions, limitations and diversification requirements that are imposed by the 1940 Act or Subchapter M of the Internal Revenue Code of 1986, as amended, which, if they had been applicable, might have adversely affected the Predecessor Fund’s performance. Effective February 27, 2018, the Fund’s investment strategy changed and ReSolve Asset Management Inc., one of the Fund’s current sub-advisors, replaced the prior sub-advisor. Consequently, prior performance does not reflect the Fund’s current operations. The Fund’s prior sub-advisor was the investment advisor to the Predecessor Fund since the Predecessor Fund’s inception.

The bar chart and accompanying performance table shown provides an indication of the risks of investing in the Fund by showing the total return of the Predecessor Fund and the Fund’s Institutional shares for each of the last 10 calendar years, and by showing how the average annual returns compare over time to the performance of a broad-based market index and an index reflecting the performance of commodity trading advisors.

The Fund’s performance provided below for the Fund’s Institutional shares prior to September 30, 2016 (for periods prior to the commencement of the Fund’s operations) is that of the Predecessor Fund, which includes all of the Predecessor Fund’s actual fees and expenses over various periods. The performance of the Predecessor Fund has not been restated to reflect the fees, expenses and fee waivers and/or expense limitations applicable to Institutional shares of the Fund. If the performance of the Predecessor Fund had been restated to reflect the applicable fees and expenses of the Fund, the performance of the Fund’s Institutional shares may have been lower.

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

The Predecessor Fund was organized as a limited partnership, did not qualify as a regulated investment company for federal income tax purposes, and did not pay dividends and distributions. As a result of its different tax treatment, the Fund is unable to show after-tax returns for periods that commenced prior to September 30, 2016.

The Fund changed investment strategy and a new sub-adviser was retained to implement the Balanced Allocation Strategy of the Fund’s portfolio effective January 1, 2025. Performance information for periods prior to January 1, 2025 does not reflect the Fund’s current investment strategy and the Fund was not managed by either of the Fund’s current Sub-Advisors prior to February 27, 2018.

Average Annual Total Returns

(For periods ended December 31, 2024)

¹ Includes the effect of performance fees paid by the investors of the Predecessor Fund.

² After Tax Returns, if any, are shown for periods beginning after September 30, 2016. As a result of the different tax treatment of the Predecessor Fund, we are unable to show the after-tax returns for periods that commenced prior to September 30, 2016. The Predecessor Fund did not have a distribution policy.

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-advantaged accounts or to shares held by non-taxable entities. After-tax returns are only shown for Institutional shares. After-tax returns for other share classes will vary.
