FUND SUMMARY – RATIONAL EQUITY ARMOR FUND

Investment Objective: The Fund’s investment objective is to seek total return on investment, with dividend income an important component of that return.

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 116 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 89.

⁽¹⁾ In the case of investments of $1 million or more (where you do not pay an initial sales charge and the selling broker receives a commission), a 1.00% contingent deferred sales charge (“CDSC”) may be assessed on shares redeemed within two years of purchase.

⁽²⁾ Maximum Deferred Sales Charge on Class C shares applies to shares sold within 12 months of purchase.

⁽³⁾ Acquired Fund Fees and Expenses are the indirect costs of investing in other investment companies. The total annual fund operating expenses in this fee table will not correlate to the expense ratio in the Fund’s financial highlights because the financial statements include only the direct operating expenses incurred by the Fund, not the indirect costs of investing in other investment companies.

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 you redeem all your shares at the end of those periods. The example assumes that the average annual return was 5% and operating expenses remain the same. Although your actual costs may be higher or lower, based on the above 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 rate 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 580% of the average value of its portfolio.

Principal Investment Strategy

The Fund seeks to achieve its investment objective by investing primarily in common stock of dividend paying companies included within the S&P 500 Index. The Fund may also invest in exchange traded funds (“ETFs”). Under normal circumstances, the Fund will invest at least 80% of its net assets, plus the amount of borrowings for investment purposes, in equity securities. The Fund seeks to hedge the majority of its stock exposure by investing up to 20% of its assets in futures contracts on the Cboe Volatility Index (the “VIX Index”) (“VIX Futures”) or other similar volatility-related futures and options contracts, and in cash and cash equivalents, including U.S. Treasury obligations, as a hedge against the common stock held in the Fund’s portfolio.

Equity Armor Investments, LLC, the investment sub-advisor of the Fund (“the “Sub-Advisor”), uses a rules-based quantitative strategy to create a portfolio primarily composed of common stock of dividend paying companies (including real estate investment trusts (“REITs”)) that it believes offer the best return potential and low volatility under the current economic environment. Stocks are selected based on a proprietary model comprised of the following factors: (i) domestic factors such as unemployment rate, corporate cash flow, housing starts, auto sales, and new durable goods; (ii) monetary factors; (iii) interest rates; (iv) various index levels including gold index, energy prices, consumer price index; and (v) international factors such as euro exchange rates, FTSE 100, Tokyo stock exchange, and agricultural exports. The goal of the strategy is to select those companies with prices that (i) are primarily driven by the economy rather than company-specific information; (ii) are neutral or suitable in the current economy; (iii) do not exhibit excessive reaction to economic changes; and (iv) have decreased in value in lesser amounts historically than the S&P 500 Index during periods of declines in the S&P 500 Index. The Fund may gain exposure to these companies through investment in ETFs if such exposure can be gained more efficiently by investing in ETFs instead of a basket of stocks. The Fund’s sector allocation typically will not exceed approximately three times the sector’s weight in the S&P 500 Index, and the Fund’s allocation to any sector shall not exceed approximately 50% of the Fund’s assets at the time of investing. The Fund’s sector allocation is assessed and rebalanced as needed. The Fund’s sector allocation process does not focus on any particular sectors.

The Fund invests in volatility futures contracts utilizing a proprietary strategy that seeks to correlate to Equity Armor Investments VOL365 Index (“EAVOL”), known as the “the EAVOL Trading Strategy.” The

EAVOL trading strategy is constructed pursuant to a rules-based volatility analysis that identifies investments that present the least potential for time decay (i.e., the decline in the value of a contract over the passage of time), while maintaining the highest correlation to near-term volatility futures price movement each day. The Fund primarily invests in VIX Futures or other similar volatility-related products and seeks to achieve high correlation to the return of the EAVOL Trading Strategy for this component of the Fund’s portfolio. Historically, volatility futures contracts tend to negatively correlate to equity price movement. Therefore, the EAVOL Trading Strategy may appreciate during times of downward equity prices or when implied volatility expectations of equities rise. Likewise, when equity prices appreciate or implied volatility expectations decline, the EAVOL Trading Strategy is likely to decline in value. Volatility analysis includes the study of price, momentum, future curves, as well as recurring price patterns. The components of the EAVOL Trading Strategy are adjusted daily. The Fund adjusts the weighting of the EAVOL Trading Strategy relative to its equity position daily as well.

The Sub-Advisor may also choose to trade securities related to the VIX Index, such as S&P 500 Index futures, options on S&P 500 Index futures, options on the S&P 500 Index and VIX Index options, as well as options on other equity indexes in order to achieve the volatility overlay to the Fund’s equity exposure, if the Sub-Advisor determines that these securities provide greater access to volatility and, at such time, the total EAVOL Trading Strategy. The use of such S&P 500 Index futures and options thereon will typically be used in adverse market conditions where the VIX Index is above 30, which is roughly two times its historical average price.

The Fund’s volatility hedging strategy aims to minimize possible losses that are common in stock indexes so that investors might be able to ride-out market swings in pursuit of their long-term investment objectives. However, the volatility overlay has an associated cost. Given the negative correlation between equity price movements and the EAVOL Trading Strategy described above, the strategy may result in a reduction in the Fund’s return. The Fund’s strategy has no annualized target for the level of volatility it seeks to achieve under normal circumstances. There may be times that the Sub-Advisor determines not to implement the Fund’s volatility hedging 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 bank deposit 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.

Class/Sector/Region Focus Risk. If the Fund invests more than 25% of its net assets in a particular asset class, or securities of issuers within a particular market sector or geographic region, it is subject to increased risk. Performance will generally depend on the performance of the class, sector or region, which may differ in direction and degree from that of the overall U.S. stock or bond markets. In addition, financial, economic, business and political developments affecting the class, sector or region may have a greater effect on the Fund.

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.

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) 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. 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.

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 Sub-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.

Hedging Risk. Hedging is a strategy in which the Fund uses options or futures 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. The Fund is not required to use hedging and may choose not to do so.

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 the Fund to effectively implement its investment strategy, 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 the 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, and sub-strategy risk.

Dividend Yield Risk. While the Fund may hold securities of companies that have historically paid a dividend, those companies may reduce or discontinue their dividends, thus reducing the yield of the Fund. Lower priced securities in the Fund may be more susceptible to these risks. Past dividend payments are not a guarantee of future dividend payments.

Equity Securities Risk. The price of the common stock 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.

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.

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.

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 investment strategies employed by the Sub-Advisor in selecting investments 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-Advisor’s judgment 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 Sub-Advisor’s judgment will produce the desired result.

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, 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 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 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/REIT Risk. The Fund’s investments in REITs are subject to the same risks as direct investments in real estate, including sensitivity to general economic downturns and the volatility of local real estate markets. REITs may have limited financial resources and their securities may trade infrequently and in limited volume, and thus they may be more volatile than other securities.

Regulatory Risk. Changes in the laws or regulations of the United States, 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, 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 Sub-Advisor’s ability to accurately anticipate the future value of a security or instrument.

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.

Volatility Risk. Significant short-term price movements could adversely impact the performance of the Fund. Market conditions in which significant price movements develop, but then repeatedly reverse, could cause substantial losses due to prices moving against the Fund’s long or short positions (which are based on prior trends). The performance of the Fund is based in part on the prices of one or more of the VIX Futures or other similar volatility-related products in which the Fund invests. Each of the equity securities held by the Fund and the VIX Futures or other similar volatility-related products are affected by a variety of factors and may change unpredictably, affecting the value of such equity securities and VIX Futures or other similar volatility-related products and, consequently, the value and the market price of the Fund’s shares.
