P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Counterparty Risk. The Fund may engage in investment transactions or other contracts with third parties ( i.e. , “counterparties”), including over-the-counter forward foreign currency contracts. The Fund bears the risk that a counterparty to these contracts becomes bankrupt, defaults on its obligations or otherwise fails to honor its obligations. If a counterparty defaults on its payment obligations, the Fund may lose money and the value of an investment in Fund Shares may decrease.

Currency Strategies Risk. Currency exchange rates may fluctuate significantly over short periods of time and can be unpredictably affected by political developments or government intervention. Changes in currency exchange rates may affect the U.S. Dollar value of the Fund’s investments, including foreign securities and forward currency contracts.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk. Derivatives, such as forward currency contracts, can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. Other risks of investments in derivatives include risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the derivative transaction may not be liquid.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Exchange-Traded Funds and Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF, ETP or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. In addition, as with investments in other ETPs, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower.

Fixed Income Risk. A decline in an issuer’s credit rating may cause a decrease in the value of its fixed income securities and an increase in their investment risk and volatility. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” (or repay) the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income. The market value of fixed income securities generally changes in response to changes in interest rates.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Forward Currency Contracts Risk. Forward currency contracts and other currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as Cambria expects.  The Fund may be required to buy or sell additional currency on the spot market (and bear the expense of such transaction) if Cambria’s predictions regarding the movement of foreign currency prove inaccurate. In addition, the use of forward currency contracts subjects the Fund to counterparty risk and leveraging risk, as discussed in this Prospectus. Forward contracts require collateralization, and the commitment of a large portion of the Fund’s assets as collateral could impede portfolio management.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. The Fund invests a significant portion of its assets in securities of companies in Asia, Europe, including Russia, and South America.

Russia Risk. The Fund may invest a significant portion of its assets in Russian securities. As a result of events involving Ukraine and the Russian Federation, the United States and the European Union have imposed sanctions on certain Russian individuals and entities. Additional broader sanctions may be imposed in the future. These sanctions may result in the decline of the value and liquidity of Russian securities and could also result in the immediate freeze of Russian securities, impairing the ability of the Fund to buy, sell, receive or deliver those securities. The Fund may seek to suspend redemptions in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine the value of its net assets.

High Yield Securities Risk. High yield securities and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. The secondary markets in which high yield securities are traded may be less liquid and more volatile than the market for higher grade securities.

Interest Rate Risk. The market value of fixed income securities generally changes in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Interest rate risk is generally lower for shorter-term investments and higher for longer-term investments. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, the Fund may be subject to significant losses.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. 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. When you sell your Shares they could be worth less than what you paid for them.

Leveraging Risk.   Certain of Fund’s investments may expose the Fund to leverage, causing the Fund to be more volatile.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. A significant, rapid rise in interest rates may result in a period of volatility and increased redemptions if Fund securities become illiquid and are forced to sell the illiquid securities at disadvantageous times or prices. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Portfolio Turnover Risk. The Fund’s strategy may result in high portfolio turnover rates, which may increase the Fund’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate net short-term capital gains.

Precious Metals Risk. The value of investments related to precious metals, such as gold, are generally very volatile, and their prices may be affected by government policy; economic, financial, social and political factors; and inflation. In addition, the Fund may incur higher custody and transaction costs for precious metal-related investments.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk . Cambria uses quantitative techniques to generate investment decisions and its processes and stock selection, and the Fund may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Sovereign Debt Securities Risk. Investments in sovereign debt obligations involve special risks not present in corporate debt obligations. The issuer of the sovereign debt or the authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and the Fund’s NAV, may be more volatile than prices of U.S. debt obligations. In the past, certain non-U.S. markets have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debts. These risks increase for lower-rated and high yield debt securities, as discussed in this Prospectus.

Tax Risk. In order to qualify for treatment as a regulated investment company for federal income tax purposes, the Fund must among other requirements, derive at least 90% of its gross income for each taxable year from “qualifying income.” “Qualifying Income” for a regulated investment company currently includes gains from currencies, however, the U.S. Treasury Department has authority to issue regulations that would exclude such foreign currency gains from “qualifying income” if such gains are not directly related to the Fund’s business of investing in stock or securities and could limit the Fund’s ability to qualify as a regulated investment company. If in any year the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends. Also, changes in the dividend policies of companies owned by the Fund and the capital resources available for these companies’ dividend payments may adversely affect the Fund.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Investment Risk. 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. When you sell your Shares, they could be worth less than what you paid for them.

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

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of the Underlying Index. As a result, the Fund expects to hold components of the Underlying Index regardless of their current or projected performance. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk . The Underlying Index uses quantitative techniques to determine whether securities should be included in the Underlying Index, and the Underlying Index may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Sector Concentration Risk.  To the extent that the Fund’s investments are concentrated in a particular sector, the Fund may be susceptible to loss due to adverse occurrences affecting that sector. As of July 31, 2018, the Fund and the Underlying Index were concentrated in the consumer discretionary and financial services sectors and had significant exposure to companies in the industrial sector.

Consumer Discretionary Sector Risk.  The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Financial Services Sector Risk.  Performance of companies in the financial services 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. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Industrial Sector Risk.  Issuers in the industrial sector are affected by supply and demand, both for their specific product or service and for industrial sector products in general. The products of such issuers may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrial sector. Issuers in the industrial sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrial sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and they may be more sensitive to market conditions.

Tracking Error Risk. Although the Fund attempts to track the performance of the Underlying Index, the Fund may not be able to duplicate its exact composition or return due to, among other things, fees and expenses paid by the Fund that are not reflected in the Underlying Index. If the Fund is small, it may experience greater tracking error to its Underlying Index than it otherwise would at higher asset levels.

Value Investment Risk. The Fund’s shareholder yield strategy is a value investment strategy that should be expected to underperform in growth markets. Value investments are subject to the risk that their intrinsic value may never be realized by the market.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Concentration Risk. To the extent the Underlying Index is concentrated in a particular industry or group of industries, the Fund is also expected to be concentrated in that industry or group of industries. As a result, the Fund may be susceptible to loss due to adverse occurrences affecting that industry or group of industries. As of July 31, 2018, neither the Fund nor the Underlying Index were concentrated in an industry or group of industries, but both had significant exposure to companies in the consumer discretionary, financial services, industrial, and materials sectors.

Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Financial Services Sector Risk. Performance of companies in the financial services 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.

The products of such issuers may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrial sector. Issuers in the industrial sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrial sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Materials Sector Risk. Issuers in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, among other factors. Issuers in the materials sector may be liable for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to Foreign Investment Risks. In addition, depositary receipts may not track the price of the underlying foreign securities, and their value may change materially at times when the U.S. markets are not open for trading.

Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends.

Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. As of July 31, 2018, the Fund invested a significant portion of its assets in securities of companies in Japan and the United Kingdom.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of the Underlying Index. As a result, the Fund expects to hold components of the Underlying Index regardless of their current or projected performance. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Concentration Risk. To the extent the Underlying Index is concentrated in a particular industry or group of industries, the Fund is also expected to be concentrated in that industry or group of industries. As a result, the Fund may be susceptible to loss due to adverse occurrences affecting that industry or group of industries. As of July 31, 2018, neither the Fund nor the Underlying Index were concentrated in an industry or group of industries, but both had significant exposure to companies in the energy, financial services, information technology, and materials sectors.

Energy Sector Risk . The energy sector includes, for example, oil, gas, and consumable fuel companies. Energy companies can be substantially impacted by, among other things, the volatility of oil prices, worldwide supply and demand, worldwide economic growth, and political instability in oil or gas producing regions such as the Middle East and Eastern Europe.

Financial Services Sector Risk. Performance of companies in the financial services 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. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Information 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. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

Materials Sector Risk. Issuers in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, among other factors. Issuers in the materials sector may be liable for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to Foreign Investment Risks.

Also, changes in the dividend policies of companies owned by the Fund and the capital resources available for these companies’ dividend payments may adversely affect the Fund.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. As of July 31, 2018, the Fund invested a significant portion of its assets in securities of companies in China, Taiwan, South Africa, and Russia.

Russia Risk. The Fund may invest a significant portion of its assets in Russian securities. As a result of recent events involving Ukraine and the Russian Federation, the United States and the European Union have imposed sanctions on certain Russian individuals and entities. Additional broader sanctions may be imposed in the future. These sanctions may result in the decline of the value and liquidity of Russian securities and could also result in the immediate freeze of Russian securities, impairing the ability of the Fund to buy, sell, receive or deliver those securities.

Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Small and Medium Capitalization Company Risk.   Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and they may be more sensitive to market conditions.

Tracking Error Risk. Although the Fund attempts to track the performance of the Underlying Index, the Fund may not be able to duplicate its exact composition or return due to, among other things, fees and expenses paid by the Fund that are not reflected in the Underlying Index. If the Fund is small, it may experience greater tracking error to its Underlying Index than it otherwise would at higher asset levels.

Value Investment Risk. The Fund’s shareholder yield strategy is a value investment strategy that should be expected to underperform in growth markets. Value investments are subject to the risk that their intrinsic value may never be realized by the market.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Exchange-Traded Funds and Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF, ETP or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. In addition, as with investments in other ETPs, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower.

Fixed Income Risk. A decline in an issuer’s credit rating may cause a decrease in the value of its fixed income securities and an increase in their investment risk and volatility. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” (or repay) the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income. The market value of fixed income securities generally changes in response to changes in interest rates.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. As of July 31, 2018, the Fund invested a significant portion of its assets in securities of companies in Asia, South America, and Europe, including Greece and Russia.

Greece Risk. The Fund may invest in the securities of Greek issuers. Recent geopolitical events in the European Union, and specifically in Greece, have destabilized Greece. The duration and outcome of the current situation cannot be predicted, and it is possible that Greece may exit the European Monetary Union, which would likely result in the redenomination and devaluation of the Greek currency and increase the potential for Greece to default on its other outstanding debts.

Events in Greece may adversely affect the value and liquidity of the Fund’s investments in Greek issuers. For example, capital controls may restrict the Fund’s ability to sell Greek securities and reinvest the proceeds. If the Athens Stock Exchange closes, current market quotations for the securities of Greek issuers normally traded there will not be available and the Fund will fair value any such securities in its portfolio. As a result, the market price of the Fund’s shares may significantly deviate from the Fund’s NAV. In addition, the unavailability of current market quotations from the Athens Stock Exchange may affect: the calculation of the value of the Underlying Index and the calculation of the Fund’s Intraday Indicative Value. As a result, the Fund’s NAV may experience increased tracking error with respect to the Underlying Index.

Russia Risk. The Fund may invest in Russian securities. As a result of recent events involving Ukraine and the Russian Federation, the United States and the European Union have imposed sanctions on certain Russian individuals and entities. Additional broader sanctions may be imposed in the future. These sanctions may result in the decline of the value and liquidity of Russian securities and could also result in the immediate freeze of Russian securities, impairing the ability of the Fund to buy, sell, receive or deliver those securities. The Fund may seek to suspend redemptions in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine the value of its net assets.

High Yield Securities Risk. High yield securities and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. The secondary markets in which high yield securities are traded may be less liquid and more volatile than the market for higher grade securities.

Interest Rate Risk. The market value of fixed income securities generally changes in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Interest rate risk is generally lower for shorter-term investments and higher for longer-term investments. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, the Fund may be subject to significant losses.

International Closed-Market Trading Risk. Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. 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. When you sell your Shares they could be worth less than what you paid for them.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. A significant, rapid rise in interest rates may result in a period of volatility and increased redemptions if Fund securities become illiquid and are forced to sell the illiquid securities at disadvantageous times or prices. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Non-Diversification Risk. The Fund is non-diversified. Investment by the Fund in securities of a limited number of issuers may expose it to greater market risk and potential monetary losses than if its assets were diversified among the securities of a greater number of issuers.

Portfolio Turnover Risk . The Fund’s strategy may result in high portfolio turnover rates, which may increase the Fund’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate net short-term capital gains.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk . Cambria uses quantitative techniques to generate investment decisions and its processes and stock selection, and the Fund may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions or other charges, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Sovereign Debt Securities Risk . Investments in sovereign and quasi-sovereign debt obligations involve special risks not present in corporate debt obligations. The issuer of the sovereign debt or the authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and the Fund’s net asset value, may be more volatile than prices of U.S. debt obligations. In the past, certain non-U.S. markets have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debts. These risks increase for lower-rated and high yield debt securities, as discussed in this Prospectus.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Concentration Risk. To the extent the Underlying Index is concentrated in a particular industry or group of industries, the Fund is also expected to be concentrated in that industry or group of industries. As a result, the Fund may be susceptible to loss due to adverse occurrences affecting that industry or group of industries. As of July 31, 2018, the Fund and the Underlying Index were concentrated in the financial services sectors and had significant exposure to companies in the energy and materials sectors.

Energy Sector Risk. The energy sector includes, for example, oil, gas, and consumable fuel companies. Energy companies can be substantially impacted by, among other things, the volatility of oil prices, worldwide supply and demand, worldwide economic growth, and political instability in oil or gas producing regions such as the Middle East and Eastern Europe.

Financial Services Sector Risk. Performance of companies in the financial services 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. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Materials Sector Risk. Issuers in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, among other factors. Issuers in the materials sector may be liable for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to Foreign Investment Risks. In addition, depositary receipts may not track the price of the underlying foreign securities, and their value may change materially at times when the U.S. markets are not open for trading.

Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends. Also, changes in the dividend policies of companies owned by the Fund and the capital resources available for these companies’ dividend payments may adversely affect the Fund.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Exchange-Traded Funds and Investment Companies Risk. The risks of investing in securities of ETFs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. As of July 31, 2018, the Fund invested a significant portion of its assets in securities of companies in Europe, including Greece and Russia.

Greece Risk. The Fund may invest in the securities of Greek issuers. Recent geopolitical events in the European Union, and specifically in Greece, have destabilized Greece. The duration and outcome of the current situation cannot be predicted, and it is possible that Greece may exit the European Monetary Union, which would likely result in the redenomination and devaluation of the Greek currency and increase the potential for Greece to default on its other outstanding debts.

Events in Greece may adversely affect the value and liquidity of the Fund’s investments in Greek issuers. For example, capital controls may restrict the Fund’s ability to sell Greek securities and reinvest the proceeds. If the Athens Stock Exchange closes, current market quotations for the securities of Greek issuers normally traded there will not be available and the Fund will fair value any such securities in its portfolio. As a result, the market price of the Fund’s shares may significantly deviate from the Fund’s NAV. In addition, the unavailability of current market quotations from the Athens Stock Exchange may affect: the calculation of the value of the Underlying Index and the calculation of the Fund’s Intraday Indicative Value. As a result, the Fund’s NAV may experience increased tracking error with respect to the Underlying Index.

Russia Risk. The Fund may invest in Russian securities. As a result of recent events involving Ukraine and the Russian Federation, the United States and the European Union have imposed sanctions on certain Russian individuals and entities. Additional broader sanctions may be imposed in the future. These sanctions may result in the decline of the value and liquidity of Russian securities and could also result in the immediate freeze of Russian securities, impairing the ability of the Fund to buy, sell, receive or deliver those securities. The Fund may seek to suspend redemptions in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine the value of its net assets.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. 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. When you sell your Shares they could be worth less than what you paid for them.

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

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of the Underlying Index. As a result, the Fund expects to hold components of the Underlying Index regardless of their current or projected performance. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk. The Underlying Index’s use of quantitative techniques to determine whether securities should be included in the Underlying Index can be adversely affected if it relies on erroneous or outdated data. In addition, the quantitative model may be or become flawed, and factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model. The Underlying Index uses quantitative techniques to determine whether securities should be included in the Underlying Index, and the Underlying Index may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Small and Medium Capitalization Company Risk.   Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and they may be more sensitive to market conditions.

Tracking Error Risk. Although the Fund attempts to track the performance of the Underlying Index, the Fund may not be able to duplicate its exact composition or return due to, among other things, fees and expenses paid by the Fund that are not reflected in the Underlying Index. If the Fund is small, it may experience greater tracking error to its Underlying Index than it otherwise would at higher asset levels.

Value Investment Risk. Value investments are subject to the risk that their intrinsic value may never be realized by the market. Value investments tend to underperform in growth markets.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below, which includes risks the Fund may be subject to due to investments in Underlying Vehicles. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Commodity Investing Risk. Investing in commodity-related companies may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings.

Currency Strategies Risk. Currency exchange rates may fluctuate significantly over short periods of time and can be unpredictably affected by political developments or government intervention. Changes in currency exchange rates may affect the U.S. Dollar value of the Fund’s investments.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk. Derivatives, such as futures, can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. Other risks of investments in derivatives include risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the derivative transaction may not be liquid.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Exchange-Traded Funds and Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF, ETP or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. In addition, as with investments in other ETPs, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower.

Fixed Income Risk. A decline in an issuer's credit rating may cause a decrease in the value of its fixed income securities and an increase in their investment risk and volatility. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” (or repay) the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income. The market value of fixed income securities generally changes in response to changes in interest rates.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

High Yield Securities Risk. High yield securities and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. The secondary markets in which high yield securities are traded may be less liquid and more volatile than the market for higher grade securities.

Interest Rate Risk. The market value of fixed income securities generally changes in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Interest rate risk is generally lower for shorter-term investments and higher for longer-term investments. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, the Fund may be subject to significant losses.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. 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. When you sell your Shares of the Fund, they could be worth less than what you paid for them.

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

Leveraging Risk.   Certain of Fund’s investments may expose the Fund to leverage, causing the Fund’s value to be more volatile.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. A significant, rapid rise in interest rates may result in a period of volatility and increased redemptions if Fund securities become illiquid and are forced to sell the illiquid securities at disadvantageous times or prices. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Momentum Investing Risk. The Fund employs a “momentum” style of investing that emphasizes investing in securities that have had higher recent price performance compared to other securities. This style of investing is subject to the risk that these securities may be more volatile than a broad cross-section of securities or that the returns on securities that have previously exhibited price momentum are less than returns on other styles of investing or the overall stock market. High momentum may also be a sign that the securities’ prices have peaked. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

Portfolio Turnover Risk . The Fund’s or an Underlying Vehicle’s strategy may result in high portfolio turnover rates, which may increase the Fund’s or an Underlying Vehicle’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate net short-term capital gains.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk . Cambria uses quantitative techniques to generate investment decisions and its processes and stock selection, and the Fund may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Real Estate Investments Risk. The Fund is subject to the risks related to investments in real estate, including declines in the real estate market, decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.

REIT Risk. In addition to the risks associated with the real estate industry, REITs are subject to additional risks, including those related to adverse governmental actions and the potential failure to qualify for tax-free pass through of income and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area or a small number of property types. As a result, investments in REITs may be volatile. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Small and Medium Capitalization Company Risk.   Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and they may be more sensitive to market conditions.

Underlying Vehicle Counterparty and Leverage Risk. Through its investments in Underlying Vehicles the Fund may be indirectly exposed to additional risks. For example, if an Underlying Vehicle contracts with a counterparty, the Fund indirectly bears the risk that the counterparty fails to honor its obligations, causing the Underlying Vehicle, and therefore the Fund, to lose money and decline in value. Derivatives used by Underlying Vehicles may include leverage, allowing them to obtain the right to a return on stipulated capital that exceeds the amount paid or invested. Use of leverage is speculative and could magnify losses. Although certain Underlying Vehicles may segregate liquid assets to cover the market value of its obligations under the derivatives, this will not prevent losses of amounts in excess of the segregated assets. Other Underlying Vehicles may not employ any risk management procedures at all, leading to even greater losses. Due to the Fund’s investments in Underlying Vehicles, the value of the Fund’s Shares may be volatile.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk. Derivatives, such as futures and options, can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. Other risks of investments in derivatives include that the transactions may result in losses that partially or completely offset gains in portfolio positions and that the derivative transaction may not be liquid.

Dividend Paying Security Risk. Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends. Also, changes in the dividend policies of companies owned by the Fund and the capital resources available for these companies’ dividend payments may adversely affect the Fund.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Exchange-Traded Funds and Investment Companies Risk. The risks of investing in securities of ETFs and other investment companies typically reflect the risks of the types of instruments in which the underlying ETF or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower.

Futures Contracts Risk. Risks associated with the use of futures contracts include the following: (i) an imperfect correlation between movements in prices of index futures contracts and movements in the value of the stock index that the instrument is designed to simulate; and (ii) the possibility of an illiquid secondary market for a futures contract and the resulting inability to close a position prior to its maturity date. Investments in futures may expose the Fund to leverage.

Investment Risk. 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. When you sell your Shares, they could be worth less than what you paid for them.

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

Leveraging Risk.   Certain of Fund’s investments may expose the Fund to leverage, causing the Fund’s value to be more volatile.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

Market Events Risk. Turbulence in the financial markets and reduced liquidity may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Momentum Investing Risk. The Fund employs a “momentum” style of investing that emphasizes investing in securities that have had higher recent price performance compared to other securities. This style of investing is subject to the risk that these securities may be more volatile than a broad cross-section of securities or that the returns on securities that have previously exhibited price momentum are less than returns on other styles of investing or the overall stock market. High momentum may also be a sign that the securities’ prices have peaked. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of the underlying securities. Options may expire unexercised, causing the Fund to lose the premium paid for them.

Portfolio Turnover Risk . The Fund’s strategy may result in high portfolio turnover rates, which may increase the Fund’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate net short-term capital gains.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk . Cambria uses quantitative techniques to generate investment decisions and its processes and stock selection, and the Fund may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Real Estate Investments Risk. The Fund is subject to the risks related to investments in real estate, including declines in the real estate market, decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.

REIT Risk. In addition to the risks associated with the real estate industry, REITs are subject to additional risks, including those related to adverse governmental actions and the potential failure to qualify for tax-free pass through of income and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area or a small number of property types. As a result, investments in REITs may be volatile. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Sector Concentration Risk. To the extent that the Fund’s investments are concentrated in a particular sector, the Fund may be susceptible to loss due to adverse occurrences affecting that sector. As of July 31, 2018, the Fund was concentrated in the consumer discretionary and financial services sectors.

Consumer Discretionary Sector Risk.  The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and international economy, interest rates, competitive and consumer confidence. Success depends heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products in the marketplace.

Financial Services Sector Risk. Performance of companies in the financial services 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. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Short Sale Risk. If a security is sold short and subsequently has to be bought back at a higher price, the Fund will realize a loss on the transaction. The amount of loss on a short sale is potentially unlimited because there is no limit on the price a shorted security might attain (as compared to a long position, where the maximum loss is the amount invested). The use of short sales may increase the Fund’s exposure to the market, and may increase losses and the volatility of returns.

Small and Medium Capitalization Company Risk.   Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies, and they may be more sensitive to market conditions.

Value Investment Risk. Value investments are subject to the risk that their intrinsic value may never be realized by the market. Value investments tend to underperform in growth markets.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below. There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Commodity Investing Risk. Investing in commodity-related companies may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings.

Concentration Risk. To the extent that the Underlying Index is concentrated in a particular industry or group of industries, the Fund is also expected to be concentrated in that industry or group of industries. As a result, the Fund may be susceptible to loss due to adverse occurrences affecting that industry or group of industries.

Currency Strategies Risk. Currency exchange rates may fluctuate significantly over short periods of time and can be unpredictably affected by political developments or government intervention. Changes in currency exchange rates may affect the U.S. Dollar value of the Fund’s investments.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Depositary Receipts Risk. The risks of investments in depositary receipts are substantially similar to Foreign Investment Risks. In addition, depositary receipts may not track the price of the underlying foreign securities, and their value may change materially at times when the U.S. markets are not open for trading.

Derivatives Risk. Derivatives, such as futures, options, and swaps, can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. Other risks of investments in derivatives include risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the derivative transaction may not be liquid.

Emerging Markets Risk. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about companies in such markets. Securities traded on emerging markets are potentially illiquid and may be subject to volatility and high transaction costs.

Equity Investing Risk. The values of equity securities could decline generally or could underperform other investments. In addition, securities may decline in value due to factors affecting a specific issuer, market or securities markets generally.

Exchange-Traded Funds and Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF, ETP or investment company invests. In addition, with such investments, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, the Fund’s operating expenses may be higher and performance may be lower. Through its investments in investment companies, the Fund may be indirectly exposed to derivatives and leverage; allowing them to obtain the right to a return on stipulated capital that exceeds the amount paid or invested. Use of leverage is speculative and could magnify losses.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. In addition, as with investments in other ETPs, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower.

Fixed Income Risk. A decline in an issuer's credit rating may cause a decrease in the value of its fixed income securities and an increase in their investment risk and volatility. During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” (or repay) the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income. The market value of fixed income securities generally changes in response to changes in interest rates.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, the Fund’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

High Yield Securities Risk. High yield securities and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. The secondary markets in which high yield securities are traded may be less liquid and more volatile than the market for higher grade securities.

Interest Rate Risk. The market value of fixed income securities generally changes in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Interest rate risk is generally lower for shorter-term investments and higher for longer-term investments. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, the Fund may be subject to significant losses.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. 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. When you sell your Shares, they could be worth less than what you paid for them.

Leveraging Risk.   Certain of Fund’s investments may expose the Fund to leverage, causing the Fund’s value to be more volatile.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. A significant, rapid rise in interest rates may result in a period of volatility and increased redemptions if Fund securities become illiquid and are forced to sell the illiquid securities at disadvantageous times or prices. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Market Events Risk. Turbulence in the financial markets and reduced liquidity in the equity markets may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government and/or Federal Reserve, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Momentum Investing Risk. The Underlying Index may identify securities that have had higher recent price performance compared to other securities. These securities may be more volatile than a broad cross-section of securities. High momentum may also be a sign that the securities’ prices have peaked. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of the underlying securities. Options may expire unexercised, causing the Fund to lose the premium paid for them.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of the Underlying Index. As a result, the Fund expects to hold components of the Underlying Index regardless of their current or projected performance. Maintaining investments regardless of market conditions or the performance of individual investments could cause the Fund’s return to be lower than if the Fund employed an active strategy.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Quantitative Security Selection Risk. The Underlying Index uses quantitative techniques to determine whether securities should be included in the Underlying Index, and the Underlying Index may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders.

Real Estate Investments Risk. The Fund is subject to the risks related to investments in real estate, including declines in the real estate market, decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market may pay brokerage commissions, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Small and Medium Capitalization Company Risk. Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. Often, small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

Sovereign Debt Securities Risk. Investments in sovereign debt obligations involve special risks not present in corporate debt obligations. The issuer of the sovereign debt or the authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and the Fund’s NAV, may be more volatile than prices of U.S. debt obligations. In the past, certain non-U.S. markets have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debts. These risks increase for lower-rated and high yield debt securities, as discussed in this Prospectus.

Swap s Contract Risk. Each swap exposes the Fund to counterparty risk when a counterparty to a financial instrument entered into by the Fund may become bankrupt or otherwise fail to perform its obligations. As a result, the Fund may experience delays in or be prevented from obtaining payments owed to it pursuant to a swap contract.

Tracking Error Risk. Although the Fund attempts to track the performance of the Underlying Index, the Fund may not be able to duplicate its exact composition or return due to, among other things, fees and expenses paid by the Fund that are not reflected in the Underlying Index. If the Fund is small, it may experience greater tracking error to its Underlying Index than it otherwise would at higher asset levels.

Value Investment Risk. Value investments are subject to the risk that their intrinsic value may never be realized by the market. Value investments tend to underperform in growth markets.

P RINCIPAL R ISKS

An investment in the Fund involves risk, including those described below.  There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk.   Derivatives, such as put options, can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. Derivatives are financial instruments that derive their performance from an underlying reference asset, such as an index. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Other risks of investments in derivatives include risks of default by the other party to the derivative transactions; risks that the transactions may result in losses that partially or completely offset gains in portfolio positions; and risks that the derivative transaction may not be liquid.

Hedging Risk. Options used by the Fund to offset its exposure to tail risk or reduce volatility may not perform as intended. There can be no assurance that the Fund’s put option strategy will be effective. It may expose the Fund to losses, e.g. , option premiums, to which it would not have otherwise been exposed if it only invested in U.S. government bonds or U.S. government bond ETFs. Further, the put option strategy may not fully protect the Fund against declines in the value of its portfolio securities.

Investment Risk.   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. When you sell your Shares, they could be worth less than what you paid for them.

Liquidity Risk. The Fund may purchase options and invest in other instruments that may be less liquid than other types of investments. The options purchased by the Fund may not always be liquid. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will be successful or that the Fund will achieve its investment objective.

Market Events Risk.   Turbulence in the financial markets and reduced liquidity in the equity markets may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund.

Options Risk. The value of the Fund’s positions in options fluctuates in response to changes in the value of the underlying index. The Fund also risks losing all or part of the cash paid for purchasing put options. Because the Fund only purchases put options, the Fund’s losses from its exposure to put options is limited to the amount of premiums paid to the option seller.

Portfolio Turnover Risk. Because the Fund “turns over” its put options every month, the Fund will incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and generating greater tax liabilities for shareholders. Portfolio turnover risk may cause the Fund’s performance to be less than you expect. While the turnover of the put options is not deemed “portfolio turnover” for accounting purposes, the economic impact to the Fund is similar to what could occur if the Fund experienced high portfolio turnover ( e.g. , in excess of 100% per year).

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Secondary Market Trading Risk.   Investors buying or selling Shares in the secondary market may pay brokerage commissions or other charges, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

PRINCIPAL RISKS

An investment in the Fund involves risk, including those described below.  There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk.  Put and call options are referred to as “derivative” instruments since their values are based on, or derived from, an underlying reference asset, such as an index. Derivatives can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Derivative instruments may be difficult to value and may be subject to wide swings in valuations caused by changes in the value of the underlying instrument. Other risks of investments in derivatives include risks that the transactions may result in losses that partially or completely offset gains in portfolio positions and risks that the derivative transaction may not be liquid. Derivative instruments may create economic leverage in the Fund, which magnifies the Fund’s exposure to the underlying instrument.

Dividend Paying Security Risk.  Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends. Also, companies owned by the Fund that have historically paid a dividend may reduce or discontinue their dividends, thus reducing the yield of the Fund.

Equity Investing Risk.  The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Hedging Risk. Options used by the Fund to reduce volatility may not perform as intended. There can be no assurance that the Fund’s option strategy will be effective. It may expose the Fund to losses, e.g. , option premiums, to which it would not have otherwise been exposed if it only invested in U.S. government bonds or U.S. government bond ETFs. Further, the option strategy may not fully protect the Fund against declines in the value of its portfolio securities.

Investment Risk.  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. When you sell your Shares, they could be worth less than what you paid for them.

Large Capitalization Companies Risk. The Fund’s investments in large capitalization companies (i.e., companies with more than $5 billion in capitalization) may underperform other segments of the market because large capitalization companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Leveraging Risk. Certain of Fund’s investments may expose the Fund to leverage, causing the Fund to be more volatile.

Liquidity Risk. The Fund may purchase options and invest in other instruments that may be less liquid than other types of investments. The options purchased by the Fund may not always be liquid. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that the Adviser’s judgments about the attractiveness, value and potential appreciation of particular investments and strategies for the Fund will be correct or produce the desired results or that the Fund will achieve its investment objective. If the Adviser fails to accurately evaluate market risk or appropriately react to current and developing market conditions, the Fund’s share price may be adversely affected.

Market Events Risk.  Turbulence in the financial markets and reduced liquidity in the equity markets may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund. In a declining stock market, stock prices for all companies (including those in the Fund’s portfolio) may decline, regardless of their long-term prospects.

Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of the underlying securities. Writing index call options reduces the Fund’s ability to profit from increases in the value of the Fund’s equity portfolio, and purchasing put options may result in the Fund’s loss of premiums paid in the event that the put options expire unexercised. To the extent that the Fund reduces its put option holdings relative to the number of call options sold by the Fund, the Fund’s ability to mitigate losses in the event of a market decline will be reduced.

Portfolio Turnover Risk. Because the Fund “turns over” a portion of its options from time to time, the Fund will incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs and may also result in a substantial amount of distributions from the Fund to be taxed as ordinary income, which may limit the tax efficiency of the Fund.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Secondary Market Trading Risk.  Investors buying or selling Shares in the secondary market may pay brokerage commissions or other charges, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Sector Concentration Risk.  To the extent that the Fund’s investments are concentrated in a particular sector, the Fund may be susceptible to loss due to adverse occurrences affecting that sector. As of July 31, 2018, the Fund had significant exposure to companies in the consumer staples, financial services, health care, industrial, and information technology sectors.

Consumer Staples Sector Risk.  The consumer staples sector includes, for example, food and drug retail and companies whose primary lines of business are food, beverage and other household items, including agricultural products. This sector can be significantly affected by, among other things, changes in price and availability of underlying commodities, rising energy prices and global and economic conditions.

Financial Services Sector Risk.  Performance of companies in the financial services 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. This sector has experienced significant losses in the recent past, and the impact of more stringent capital requirements and of recent or future regulation on any individual financial company or on the sector as a whole cannot be predicted.

Health Care Sector Risk. The health care sector includes, for example, biotechnology, pharmaceutical, health care facilities, and health care equipment and supply companies. This sector can be significantly affected by, among other things, lapsing patent protection, technological developments that make drugs obsolete, government regulation, price controls, and approvals for drugs.

Industrial Sector Risk.  Issuers in the industrial sector are affected by supply and demand, both for their specific product or service and for industrial sector products in general. The products of such issuers may face obsolescence due to rapid technological developments and frequent new product introduction. Government regulations, world events, economic conditions and exchange rates affect the performance of companies in the industrial sector. Issuers in the industrial sector may be adversely affected by liability for environmental damage, product liability claims and exchange rates. The industrial sector may also be adversely affected by changes or trends in commodity prices, which may be influenced by unpredictable factors.

Information 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. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies.

PRINCIPAL RISKS

An investment in the Fund involves risk, including those described below.  There is no assurance that the Fund will achieve its investment objective . An investor may lose money by investing in the Fund.

Cash Redemption Risk. The Fund’s investment strategy will require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may pay out higher annual capital gain distributions and be less tax-efficient than if the in-kind redemption process was used exclusively. In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Commodity Investing Risk. The Fund may invest in commodity-related companies, commodity futures and physical commodities through the Underlying Vehicles. These investments may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in an Underlying Vehicle’s holdings.

Currency Strategies Risk. Currency exchange rates may fluctuate significantly over short periods of time and can be unpredictably affected by political developments or government intervention. Changes in currency exchange rates may affect the U.S. dollar value of the Fund’s investments in Underlying Vehicles with exposure to global regions and foreign securities.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, market makers, Authorized Participants, or the issuers of securities in which the Fund invests may subject the Fund to many of the same risks associated with direct cyber security breaches.

Derivatives Risk.  Call options are referred to as “derivative” instruments since their values are based on, or derived from, an underlying reference asset, such as the Underlying Vehicles. Derivatives can be volatile, and a small investment in a derivative can have a large impact on the performance of the Fund as derivatives can result in losses in excess of the amount invested. The return on a derivative instrument may not correlate with the return of its underlying reference asset. Derivative instruments may be difficult to value and may be subject to wide swings in valuations caused by changes in the value of the underlying instrument. Other risks of investments in derivatives include risks that the transactions may result in losses that partially or completely offset gains in portfolio positions and risks that the derivative transaction may not be liquid. Derivative instruments may create economic leverage in the Fund, which magnifies the Fund’s exposure to the underlying instrument.

Emerging Markets Risk. Underlying Vehicles may be comprised of emerging market securities. Emerging market countries are typically described as developing nations that are making progress toward joining the developed world and have more advanced economies and infrastructure than frontier market countries. Emerging market investments are subject to the same risks as foreign investments and to additional risks due to greater political and economic uncertainties as well as a relative lack of information about issuers in such markets. Securities of emerging market issuers may become illiquid and be subject to volatility and high transaction costs.

Equity Investing Risk.  Underlying Vehicles may be comprised of equities. The values of equity securities could decline generally or could underperform other investments due to factors affecting a specific issuer, market or securities markets generally.

Exchange-Traded Funds, Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the underlying ETF, ETP or investment company invests. ETFs, ETPs and investment companies may invest in derivatives; to the extent that one does so, the Fund will be exposed to the risks of derivatives, including potentially counterparty and leverage risks. In addition, when the Fund invests in ETFs, ETPs and investment companies, the Fund bears its proportionate share of the fees and expenses of the underlying entity. As a result, an investment by the Fund in an ETF, ETP or investment company may cause the Fund’s operating expenses to be higher and, in turn, performance to be lower than if the Fund were to invest directly in the securities underlying the ETF, ETP or investment company.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. In addition, as with investments in other ETPs, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower.

Fixed Income Risk. Underlying Vehicles may be comprised of fixed income securities. A decline in an issuer’s credit rating may cause a decrease in the value of its fixed income securities and an increase in their investment risk and volatility. During periods of falling interest rates, an issuer of a callable bond held by an Underlying Vehicle may “call” (or repay) the security before its stated maturity, and the Underlying Vehicle may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Underlying Vehicle’s and the Fund’s income. The market value of fixed income securities generally changes in response to changes in interest rates, as described in greater detail below.

Foreign Investment Risk. Underlying Vehicles may be comprised of foreign securities. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Exposures to foreign securities entail special risks, including risks due to: (i) differences in information available about foreign issuers; (ii) differences in investor protection standards in other jurisdictions; (iii) capital controls risks, including the risk of a foreign jurisdiction imposing restrictions on the ability to repatriate or transfer currency or other assets; (iv) political, diplomatic and economic risks; (v) regulatory risks; and (vi) foreign market and trading risks, including the costs of trading and risks of settlement in foreign jurisdictions. In addition, an Underlying Vehicle’s investments in securities denominated in other currencies could decline due to changes in local currency relative to the value of the U.S. dollar, which may affect the Underlying Vehicle’s and the Fund’s returns.

Geographic Investment Risk.  To the extent the Fund invests a significant portion of its assets in Underlying Vehicles that invest in securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region.

Hedging Risk. Options used by the Fund to reduce volatility may not perform as intended. There can be no assurance that the Fund’s option strategy will be effective. It may expose the Fund to losses, e.g. , reduced profits from portfolio gains, to which it would not have otherwise been exposed if it only invested in Underlying Vehicles. Further, the option strategy does not protect the Fund against declines in the value of its portfolio securities.

High Yield Securities Risk. Underlying Vehicles may be comprised of high yield securities. High yield securities and unrated securities of comparable credit quality are subject to the increased risk of an issuer’s inability to meet principal and interest payment obligations. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. The secondary markets in which high yield securities are traded may be less liquid and more volatile than the market for higher grade securities.

Interest Rate Risk. The market value of fixed income securities, and financial instruments related to fixed income securities, will change in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Longer maturity securities tend to be more sensitive to changes in interest rates and more volatile; and thus an Underlying Vehicle with a longer portfolio maturity generally is subject to greater interest rate risk. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, an Underlying Vehicle investing in fixed incomes securities, and the Fund, may be subject to significant losses.

International Closed-Market Trading Risk. Because an Underlying Vehicle’s investments may be traded in markets that are closed when the Underlying Vehicle’s listing exchange is open, there are likely to be deviations between the current pricing of an Underlying Vehicle’s underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk.  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. When you sell your Shares, they could be worth less than what you paid for them.

Large Capitalization Companies Risk. The Fund’s investments in Underlying Vehicles that are comprised of large capitalization companies may underperform other segments of the market because large capitalization companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

Leveraging Risk. Certain of the Fund’s investments may expose the Fund to leverage, causing the Fund’s value to be more volatile.

Liquidity Risk. The Fund may sell options and invest in other instruments that may be less liquid than other types of investments. The options sold by the Fund may not always be liquid. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that the Adviser’s judgments about the attractiveness, value and potential appreciation of particular investments and strategies for the Fund will be correct or produce the desired results or that the Fund will achieve its investment objective. If the Adviser fails to accurately evaluate market risk or appropriately react to current and developing market conditions, the Fund’s share price may be adversely affected.

Market Events Risk.  Turbulence in the financial markets and reduced liquidity in the equity markets may negatively affect issuers, which could have an adverse effect on the Fund. In addition, there is a risk that policy changes by the U.S. Government, Federal Reserve and/or other government actors, such as increasing interest rates, could cause increased volatility in financial markets and higher levels of Fund redemptions, which could have a negative impact on the Fund. In a declining stock market, stock prices for all companies (including those in an Underlying Vehicle’s portfolio) may decline, regardless of their long-term prospects.

Options Risk. The prices of options may change rapidly over time and do not necessarily move in tandem with the price of their underlying securities. Writing call options may reduce the Fund’s ability to profit from increases in the value of the Fund’s Underlying Vehicle portfolio. When writing call options on an Underlying Vehicle, the Fund receives a premium; however, the premium may not be enough to offset a loss incurred by the Fund if the price of the Underlying Vehicle is above the strike price by an amount equal to or greater than the premium. The Fund’s option strategy is designed to provide the Fund with income by taking in options premiums, but it is not designed to mitigate losses to the Fund in the event of a market decline.

Portfolio Turnover Risk. Because the Fund “turns over” a portion of its options from time to time, the Fund will incur high levels of transaction costs from commissions or mark-ups in the bid/offer spread. Higher portfolio turnover may result in the Fund paying higher levels of transaction costs. The Fund’s or an Underlying Vehicle’s strategy may result in high turnover rates, which may increase the Fund’s or an Underlying Vehicle’s brokerage commission costs and negatively impact the Fund’s performance. Such portfolio turnover also may generate net short-term capital gains.

Premium-Discount Risk.  The Shares may trade above (premium) or below (discount) their net asset value (or “NAV”). The market prices of Shares will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. This risk is heightened in times of market volatility or periods of steep market declines.

Real Estate Investments Risk. Underlying Vehicles may be comprised of real estate securities. The Fund is subject to the risks related to investments in real estate, including declines in the real estate market, decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.

REIT Risk. Underlying Vehicles may be comprised of REITs. In addition to the risks associated with the real estate industry, REITs are subject to additional risks, including those related to adverse governmental actions and the potential failure to qualify for tax-free pass through of income and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area or a small number of property types. As a result, investments in REITs may be volatile. REITs are pooled investment vehicles with their own fees and expenses and the Underlying Vehicle, as well as the Fund, will indirectly bear a proportionate share of those fees and expenses.

Secondary Market Trading Risk.  Investors buying or selling Shares in the secondary market may pay brokerage commissions or other charges, which may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted.

Small and Medium Capitalization Company Risk. The Fund’s investments in Underlying Vehicles that are comprised of small and medium capitalization companies involve greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. Often small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

Tax Risk.   The writing of call options by the Fund may significantly reduce or eliminate its ability to make distributions eligible to be treated as qualified dividend income, which is generally taxable to non-corporate shareholders at a lower rate.  Covered call options are also subject to federal tax rules that: (1) limit the allowance of certain losses or deductions by the Fund; (2) convert the Fund’s long-term capital gains into higher taxed short-term capital gains or ordinary income; (3) convert the Fund’s ordinary losses or deductions into capital losses, the deductibility of which are more limited; and/or (4) cause the Fund to recognize income or gains without a corresponding receipt of cash.

Underlying Vehicle Counterparty and Leverage Risk. The Fund may be exposed to additional risks due to the nature of the investment programs of the Underlying Vehicles. The Underlying Vehicles may engage in investment transactions or other contracts with third parties ( i.e. , “counterparties”). They bear the risk that the counterparty to these contracts becomes bankrupt, defaults on its obligations or otherwise fails to honor its obligations and may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding involving the counterparty. If a counterparty defaults on its payment obligations, the Underlying Vehicle, and therefore the Fund, will lose money and the value of an investment in Fund Shares may decrease. Derivatives used by the Underlying Vehicles may include leverage, allowing them to obtain the right to a return on stipulated capital that exceeds the amount paid or invested. Although Underlying Vehicles registered under the Investment Company Act of 1940 (the “Investment Company Act”) will segregate or earmark liquid assets to cover the market value of its obligations under certain derivatives, the amount will be limited to the current value of the obligations to the counterparty, and will not prevent losses greater than the value of those obligations, and Underlying Vehicles not so registered may not have such cover obligations. The use of derivatives could cause the Fund to be more volatile, resulting in larger gains or losses in response to changes in the values of the securities subject to the derivative than direct investments. Use of leverage involves special risks and is speculative and could magnify any losses, and such losses may be significant.

P RINCIPAL R ISKS

Cash Redemption Risk. The Fund’s investment strategy may require it to effect redemptions, in whole or in part, for cash. As a result, the Fund may be required to sell portfolio securities in order to obtain the cash needed to distribute redemption proceeds. This may cause the Fund to recognize investment income and/or capital gains or losses that it might not have recognized if it had completely satisfied the redemption in-kind. As a result, the Fund may be less tax efficient if it includes such a cash payment than if the in-kind redemption process was used exclusively ( i.e. , securities are distributed as payment of redemption proceeds). In addition, cash redemptions may incur higher brokerage costs than in-kind redemptions and these added costs may be borne by the Fund and negatively impact Fund performance.

Commodity I nvesting Risk. Investing in commodity-related companies may subject the Fund to greater volatility than investments in traditional securities. The commodities markets have experienced periods of extreme volatility. Similar future market conditions may result in rapid and substantial valuation increases or decreases in the Fund’s holdings. The commodities markets may fluctuate widely based on a variety of factors. Movements in commodity investment prices are outside of the Fund’s control and may not be anticipated. Price movements may be influenced by, among other things: governmental, agricultural, trade, fiscal, monetary and exchange control programs and policies; changing market and economic conditions; market liquidity; weather and climate conditions; changing supply and demand relationships and levels of domestic production and imported commodities; the availability of local, intrastate and interstate transportation systems; energy conservation; the success of exploration projects; changes in international balances of payments and trade; domestic and foreign rates of inflation; currency devaluations and revaluations; domestic and foreign political and economic events; domestic and foreign interest rates and/or investor expectations concerning interest rates; foreign currency/exchange rates; domestic and foreign governmental regulation and taxation; war, acts of terrorism and other political upheaval and conflicts; governmental expropriation; investment and trading activities of investment companies, hedge funds and commodities funds; and changes in philosophies and emotions of market participants. The frequency and magnitude of such changes cannot be predicted.

Concentration (or Sector Concentration ) Risk. To the extent that the Fund’s investments are concentrated in a particular sector, industry or group of industries, the Fund may be susceptible to loss due to adverse occurrences affecting that industry or group of industries. Each Index Fund is expected to be concentrated in a particular sector, industry or group of industries to the extent that its Underlying Index is concentrated in that sector, industry or group of industries.

Consumer Discretionary Sector Risk. Consumer discretionary products and services are non-essential products and services whose demand tends to increase as consumers' disposable income increases, such as automobiles, apparel, electronics, home furnishings, and travel and leisure products and services. These companies may include, for example, publishers; catalog and internet retailers; department stores and specialty retailers including apparel, electronics, automotive, and home furnishing stores; manufacturers of auto parts and accessories, tire and rubber, autos, motorcycles, and scooters; manufacturers of consumer electronic products, including TVs and DVD players; manufacturers of household appliances and home furnishings; residential construction companies; manufacturers of leisure products; manufacturers of apparel, accessories, footwear, textiles, and luxury goods; gaming facility, hotel, cruise and travel agency owners and operators; restaurants and caterers; companies providing educational, home security, legal, and personal services; advertising and public relations companies; and TV and cable companies. This sector can be significantly affected by the performance of the overall economy, interest rates, competition, and consumer confidence. Success can depend heavily on disposable household income and consumer spending. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer discretionary products.

Consumer Staples Sector Risk. The consumer staples sector includes, for example, food and drug retail and companies whose primary lines of business are food, beverage and other household items, including agricultural products. This sector can be significantly affected by, among other things, changes in price and availability of underlying commodities, rising energy prices, tariffs and trade barriers, consumer confidence, and global and economic conditions. Consumer staples companies depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may also be subject to severe competition. Unlike the consumer discretionary sector, companies in the consumer staples sector have historically been characterized as non-cyclical in nature and therefore less volatile in times of change.

Energy Sector Risk. The energy sector includes, for example, oil, gas, and consumable fuel companies. Energy companies can be substantially impacted by, among other things, the volatility of oil prices, worldwide supply and demand, worldwide economic growth, and political instability in oil or gas producing regions such as the Middle East and Eastern Europe. Energy companies and the price of their securities are also affected by the success of exploration projects, exploration and production spending, swift price and supply fluctuations, energy conservation, currency exchange rates, and increased competition and technological advances. Energy companies may also be adversely impacted by substantial government regulation, tax policies, general civil liabilities, and liabilities for environmental damage. Companies in this sector may also be subject to contractual fixed pricing, which may increase the cost of doing business and limit these companies’ earnings. A significant portion of revenues of these companies depends on a relatively small number of customers, including governmental entities and utilities. As a result, governmental budget constraints may have a material adverse effect on the stock prices of energy companies. Energy companies may also operate in or engage in transactions involving countries with less developed regulatory regimes or a history of expropriation, nationalization or other adverse policies. Declines in the demand for, or prices of, energy generally would be expected to negatively impact the value of the Fund’s investments in energy securities. Such declines may occur quickly and without warning.

Financial Services Sector Risk. The financial services sector includes companies involved in such activities as banking, commercial and consumer finance, investment banking, brokerage, asset management, custody and insurance. Companies in the financial services sector may be subject to extensive government regulation that affects the scope of their activities, the prices they can charge and the amount of capital they must maintain. The profitability of companies in the financial services sector may be adversely affected by increases in interest rates. The profitability of companies in the financial services sector may be adversely affected by loan losses, which usually increase in economic downturns. In addition, the financial services sector in certain countries is undergoing numerous changes, including continuing consolidations, development of new products and structures and changes to its regulatory framework, which may have an impact on the issuers included in the Underlying Index. Furthermore, increased government involvement in the financial services sector, including measures such as taking ownership positions in financial institutions, could result in a dilution of the Fund’s investments in financial institutions.

Health Care Sector Risk. The health care sector includes, for example, biotechnology, pharmaceutical, health care facilities, and health care equipment and supply companies. Companies in the health care sector are regulated extensively by the government and their profits can be significantly affected by, among other things, the rising costs of medical products and services, restrictions on the government’s reimbursement for medical expenses, price controls, and expenses associated with the drug approval process, including research and development. Health care companies also rely upon the protection of patents and may be adversely impacted by lapsing patents or the cost associated with defending a patent through litigation. These companies may also be negatively affected by technological developments or industry innovations that make their drugs, treatments, or medical products obsolete. Health care companies are also subject to litigation based on product liability and related claims.

Industrial Sector Risk. The industrial sector includes companies engaged in the manufacture and distribution of capital goods, such as those used in defense, construction and engineering, companies that manufacture and distribute electrical equipment and industrial machinery and those that provide commercial and transportation services and supplies. Companies in the industrial sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, companies in the industrial sector may be adversely affected by environmental damages, product liability claims and exchange rates. The success of these companies is affected by supply and demand both for their specific product or service and for industrial sector products in general. The products of manufacturing companies may face product obsolescence due to rapid technological developments and frequent new product introduction. In addition, the industrial sector may also be adversely affected by changes or trends in commodity prices, which may be unpredictable.

Information Technology Sector Risk. Technology companies are characterized by periodic new product introductions, innovations and evolving industry standards, and, as a result, face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Companies in the technology sector are often smaller and less experienced companies and may be subject to greater risks than larger companies; these risks may be heightened for technology companies in foreign markets. Technology companies may have limited product lines, markets, financial resources or personnel. The products of technology companies may face product obsolescence due to rapid technological developments and frequent new product introduction, changes in consumer and business purchasing patterns, unpredictable changes in growth rates and competition for the services of qualified personnel. In addition, a rising interest rate environment tends to negatively affect companies in the technology sector because, in such an environment, those companies with high market valuations may appear less attractive to investors, which may cause sharp decreases in the companies’ market prices. Companies in the technology sector are heavily dependent on patent and intellectual property rights. The loss or impairment of these rights may adversely affect the profitability of these companies. The technology sector may also be adversely affected by changes or trends in commodity prices, which may be influenced or characterized by unpredictable factors. Finally, while all companies may be susceptible to network security breaches, certain companies in the technology sector may be particular targets of hacking and potential theft of proprietary or consumer information or disruptions in service, which could have a material adverse effect on their businesses.

Materials Sector Risk. Issuers in the materials sector may be adversely affected by commodity price volatility, exchange rates, import controls, increased competition, depletion of resources, technical progress, labor relations and government regulations, and mandated expenditures for safety and pollution control, among other factors. Issuers in the materials sector are at risk of liability for environmental damage and product liability claims. Production of materials may exceed demand as a result of market imbalances or economic downturns, leading to poor investment returns.

Counterparty Risk. The Fund may engage in investment transactions or other contracts with third parties ( i.e. , “counterparties”), including over-the-counter forward foreign currency contracts. For example, the Fund may enter into forward currency contracts or repurchase agreements. The Fund bears the risk that the counterparty to these contracts becomes bankrupt, defaults on its obligations or otherwise fails to honor its obligations. The Fund may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding. The Fund may obtain only limited recovery or may obtain no recovery in these circumstances. If a counterparty defaults on its payment obligations, the Fund will lose money and the value of an investment in Fund Shares may decrease.

Currency Strategies Risk. Currency exchange rates may fluctuate significantly over short periods of time and can be unpredictability affected by political developments or government intervention. Changes in currency exchange rates may affect the U.S. Dollar value of the Fund’s investments, including foreign securities, forward contracts, money market instruments or other high quality debt securities, or investment companies that invest in those instruments. To the extent that a foreign government moves to devalue a currency to which the Fund has exposure, such action could cause the Fund to lose money.

Cyber Security Risk. The Fund, and its service providers, may be susceptible to operational and information security risks resulting from a breach in cyber security, including cyber-attacks. A breach in cyber security, intentional or unintentional, may adversely impact the Fund in many ways, including, but not limited to, disruption of the Fund’s operational capacity, loss of proprietary information, theft or corruption of data maintained online or digitally, denial-of-service attacks on websites or network resources, and the unauthorized release of confidential information. Cyber-attacks affecting the Fund’s third-party service providers, including Cambria, the custodian, and the transfer agent, may subject the Fund to many of the same risks associated with direct cyber security breaches and adversely impact the Fund. For instance, cyber-attacks may impact the Fund’s ability to calculate its NAV, cause the release of confidential business information, impede trading, cause the Fund to incur additional compliance costs associated with corrective measures, subject the Fund to regulatory fines or other financial losses, and/or cause reputational damage to the Fund. Cyber security breaches of market makers, Authorized Participants, or the issuers of securities in which the Fund invests could also have material adverse consequences on the Fund’s business operations and cause financial losses for the Fund and its shareholders. While the Fund and its service providers have established business continuity plans and risk management systems designed to address cyber security risks, prevent cyber-attacks and mitigate the impact of cyber security breaches, there are inherent limitations on such plans and systems. In addition, the Fund has no control over the cyber security protections put in place by its service providers or any other third parties whose operations may affect the Fund or its shareholders.

Depositary Receipts Risk. The Fund’s investments in foreign companies may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”). ADRs, EDRs, and GDRs are generally subject to the risks of investing directly in foreign securities and, in some cases, there may be less information available about the underlying issuers than would be the case with a direct investment in the foreign issuer. ADRs are U.S. dollar-denominated receipts representing shares of foreign-based corporations. GDRs are similar to ADRs but are shares of foreign-based corporations generally issued by international banks in one or more markets around the world. Investment in ADRs and GDRs may be less liquid than the underlying shares in their primary trading market and GDRs, many of which are issued by companies in emerging markets, may be more volatile. Depositary receipts may be “sponsored” or “unsponsored” and may be unregistered and unlisted.   Sponsored depositary receipts are established jointly by a depositary and the underlying issuer, whereas unsponsored depositary receipts may be established by a depositary without participation by the underlying issuer. Holders of an unsponsored depositary receipt generally bear all the costs associated with establishing the unsponsored depositary receipt. In addition, the issuers of the securities underlying unsponsored depositary receipts are not obligated to disclose material information in the United States and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the depositary receipts. The Fund’s investments may also include ADRs and GDRs that are not purchased in the public markets and are restricted securities that can be offered and sold only to “qualified institutional buyers” under Rule 144A of the Securities Act of 1933, as amended. Cambria   will determine the liquidity of these investments pursuant to guidelines established by the Board. If a particular investment in such ADRs or GDRs is deemed illiquid, that investment will be included within the Fund’s limitation on investment in illiquid securities. Moreover, if adverse market conditions were to develop during the period between the Fund’s decision to sell these types of ADRs or GDRs and the point at which the Fund is permitted or able to sell such security, the Fund might obtain a price less favorable than the price that prevailed when it decided to sell.

Derivatives Risk. Derivatives are financial instruments that have a value which depends upon, or is derived from, a reference asset, such as one or more underlying securities, pools of securities, indexes, rates or currencies. Derivatives may result in investment exposures that are greater than their cost would suggest; in other words, a small investment in a derivative may have a large impact on Fund performance. The successful use of derivatives generally depends on the ability to predict market movements. The use of these instruments requires special skills and knowledge of investment techniques that are different than those normally required for purchasing and selling securities. If the Adviser uses a derivative instrument at the wrong time or judges market conditions incorrectly, or if the derivative instrument does not perform as expected, these strategies may significantly reduce the Fund’s return. The Fund could also experience losses if it is unable to close out a position because the market for an instrument or position is or becomes illiquid.

Derivatives, including swaps, options, futures and forward currency contracts, are subject to a number of risks, some of which are described elsewhere in this Prospectus. The use of derivatives may entail risks greater than, or possibly different from, such risks to which the Fund is exposed. Certain of the different risks to which the Fund might be exposed due to the use of derivatives include the following:

Dividend Paying Security Risk.  Securities that pay high dividends as a group can fall out of favor with the market, causing these companies to underperform companies that do not pay high dividends. Also, changes in the dividend policies of and capital resources available to companies owned by the Fund that have historically paid a dividend may adversely impact the Fund’s yield if these companies reduce or discontinue their dividends. Lower priced securities in the Fund may be more susceptible to these risks. Past dividend payments are not a guarantee of future dividend payments.

Emerging Markets Risk. Investments in securities and instruments traded in developing or emerging markets, or that provide exposure to these   securities or markets, can involve additional risks relating to political, economic, or regulatory conditions not associated with   investments in U.S. securities and instruments or investments in more developed international markets. For example,   emerging markets may be subject to, among other risks, greater market volatility; lower trading volume and liquidity; greater social,   political and economic uncertainty; governmental controls on foreign investments and limitations on repatriation of   invested capital; lower disclosure, corporate governance, auditing and financial reporting standards; fewer protections   of property rights; restrictions on the transfer of securities or currency; and settlement and trading practices that   differ from U.S. markets and markets of more developed countries. Each of these factors may impact the ability of the Fund to buy, sell or otherwise transfer securities,   adversely affect the trading market and price for Fund Shares and cause the Fund to decline in value.

Equity Investing Risk. An investment in the Fund involves risks similar to those of investing in any fund holding equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices. The values of equity securities could decline generally or could underperform other investments. Different types of equity securities tend to go through cycles of outperformance and underperformance in comparison to the general securities markets. In addition, securities may decline in value due to factors affecting a specific issuer, market or securities markets generally. Recent unprecedented turbulence in financial markets, reduced liquidity in credit and fixed income markets, or rising interest rates may negatively affect many issuers worldwide, which may have an adverse effect on the Fund.

Exchange-Traded Funds, Exchange-Traded Products and Investment Companies Risk. The risks of investing in securities of ETFs, ETPs and investment companies typically reflect the risks of the types of instruments in which the ETF, ETP or investment company invests. When the Fund invests in these securities, shareholders of the Fund bear their proportionate share of the fees and expenses of the ETF, ETP or other investment company, as well as their share of the Fund’s fees and expenses. As a result, an investment by the Fund in an ETF, ETP or investment company could cause the Fund’s operating expenses to be higher and performance to be lower.

Through its investments in investment companies, the Fund may be indirectly exposed to additional risks. Derivatives used by investment companies in which the Fund may invest may cause them to become leveraged, allowing them to obtain the right to a return on stipulated capital that exceeds the amount paid or invested. Use of leverage is speculative and could magnify losses. Although certain investment companies may segregate liquid assets to cover the market value of its obligations under the derivatives, this will not prevent losses of amounts in excess of the segregated assets. Other investment companies may not employ any risk management procedures at all, leading to even greater losses.

Exchange-Traded Notes Risk. Because ETNs are unsecured, unsubordinated debt securities, an investment in an ETN exposes the Fund to the risk that an ETN’s issuer may be unable to pay. As a result, the value of the ETN may decline, including to zero. In addition, as with investments in other ETPs, ETFs and investment companies, the Fund will bear its proportionate share of the fees and expenses of the ETN, which may cause the Fund’s operating expenses to be higher and its performance to be lower than it would if it invested directly in the securities of the index or other reference assets of the ETN.

Fixed Income Risk. The financial condition of an issuer of a fixed-income security may cause the issuer to default. A decline in an issuer's credit rating may cause a decrease in the value of the security and an increase in investment risk and price volatility.   During periods of falling interest rates, an issuer of a callable bond held by the Fund may “call” (or repay) the security before its stated maturity, and the Fund may have to reinvest the proceeds at lower interest rates, resulting in a decline in the Fund’s income.   The market value of fixed income securities, and financial instruments related to fixed income securities, generally changes in response to changes in interest rates and may change in response to other factors, such as perception of an issuer’s creditworthiness. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. While securities with longer maturities tend to produce higher yields, the prices of longer maturity securities tend to be more sensitive to changes in interest rates and thus subject to greater volatility than securities with shorter maturities. A fund with a longer portfolio maturity generally is subject to greater interest rate risk. Changes in interest rates may also have an impact on equity markets. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. The Federal Reserve increased interest rates twice in 2017 and twice in the first half of 2018 and indicated that two more increases are likely in 2018. To the extent that rates increase substantially and/or rapidly, the Fund may be subject to significant losses.

Foreign Investment Risk. The Fund may invest in foreign securities, including non-U.S. dollar-denominated securities traded outside of the United States and U.S. dollar-denominated securities of foreign issuers traded in the United States. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in foreign securities, including investments in depositary receipts, are subject to special risks, including the following:

Foreign Securities Risk . Investments in non-U.S. securities involve certain risks that may not be present with investments in U.S. securities. For   example, investments in non-U.S. securities may be subject to risk of loss due to foreign currency fluctuations or to political or   economic instability. There may be less information publicly available about non-U.S. issuers. Non-U.S.   issuers may be subject to different accounting, auditing, financial reporting and investor protection standards. Changes to the financial condition or credit rating of foreign issuers may also adversely affect the value of the Fund’s securities. Investments in non-U.S. securities may be subject to withholding or other taxes and may be subject to additional   trading, settlement, custodial, and operational risks. Because legal systems differ, there is also the possibility that it will   be difficult to obtain or enforce legal judgments in certain countries. Since foreign exchanges may be open on days when the Fund does not price its Shares, the value of the securities in the Fund’s portfolio may change on days when shareholders will not be able to purchase or sell Shares. Conversely, Shares may trade on days when foreign exchanges are closed. Investment in foreign securities may involve higher costs than investment in U.S. securities, including higher transaction and custody costs as well as the imposition of additional taxes by foreign governments. Each of these factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

Capital Controls Risk .   Economic conditions, such as volatile currency exchange rates and interest rates, political events and other conditions may, without prior warning, lead to government intervention and the imposition of “capital controls” or expropriation or nationalization of assets. The possible establishment of exchange controls or freezes on the convertibility of currency, or the adoption of other governmental restrictions, might adversely affect an investment in foreign securities. Capital controls include the prohibition of, or restrictions on, the ability to transfer currency, securities or other assets within or out of a jurisdiction. Levies may be placed on profits repatriated by foreign entities (such as the Fund). Capital controls may impact the ability of the Fund to buy, sell or otherwise transfer securities or currency, may adversely affect the trading market and price for Shares, and may cause the Fund to decline in value.

Currency Risk . The Fund’s net asset value is determined on the basis of U.S. dollars; therefore, the Fund may lose value if the local currency of a foreign market depreciates against the U.S. dollar, even if the local currency value of the Fund’s holdings goes up. Currency exchange rates may fluctuate significantly over short periods of time. Currency exchange rates also can be affected unpredictably by intervention; by failure to intervene by U.S. or foreign governments or central banks; or by currency controls or political developments in the U.S. or abroad. Changes in foreign currency exchange rates may affect the NAV of the Fund and the price of the Shares. Devaluation of a currency by a country’s government or banking authority would have a significant impact on the value of any investments denominated in that currency.

Political and Economic Risk . The Fund is subject to foreign political and economic risk not associated with U.S. investments, meaning that political events (civil unrest, national elections, changes in political conditions and foreign relations, imposition of exchange controls and repatriation restrictions), social and economic events (labor strikes, rising inflation) and natural disasters occurring in a foreign country could cause the Fund’s investments to experience gains or losses. The Fund also could be unable to enforce its ownership rights or pursue legal remedies in countries where it invests.

Foreign Market and Trading Risk . The trading markets for many foreign securities are not as active as U.S. markets and may have less governmental regulation and oversight. Foreign markets also may have clearance and settlement procedures that make it difficult for the Fund to buy and sell securities. The procedures and rules governing foreign transactions and custody (holding of the Fund’s assets) also may involve delays in payment, delivery or recovery of money or investments. These factors could result in a loss to the Fund by causing the Fund to be unable to dispose of an investment or to miss an attractive investment opportunity, or by causing Fund assets to be uninvested for some period of time.

Forward Currency Contracts Risk. Forward currency contracts and other currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as Cambria expects.  The Fund may be required to buy or sell additional currency on the spot market (and bear the expense of such transaction) if Cambria’s predictions regarding the movement of foreign currency prove inaccurate. In addition, the use of forward currency contracts subjects the Fund to counterparty risk and leveraging risk, as discussed in this Prospectus. Forward contracts require collateralization, and the commitment of a large portion of the Fund’s assets as collateral could impede portfolio management.

Futures Contracts Risk. Futures contracts are a type of derivative investment. A derivative refers to any financial instrument whose value is derived, at least, in part, from the price of another security or a specified index, asset or rate. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Derivatives can be highly complex and their use within a management strategy can require specialized skills.

Futures contracts may experience dramatic price changes (losses) and imperfect correlations between the price of the contract and the foreign currency, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). There may not be a liquid secondary market for a futures contract. When the Fund purchases or sells a futures contract, it is subject to daily variation margin calls that could be substantial. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous.

Geographic Investment Risk . To the extent that the Fund invests a significant portion of its assets in the securities of companies of a single country or region, it is more likely to be impacted by events or conditions affecting that country or region. For example, economic and political conditions and changes in tax, regulatory, or economic policy in a country could significantly affect the market in that country and in surrounding or related countries and have a negative impact on the Fund’s performance.

Asia-Pacific Risk. Investments in securities of issuers in Asia-Pacific countries involve risks that are specific to the Asia-Pacific region, including certain legal, regulatory, political and economic risks. Certain Asia-Pacific countries have experienced expropriation and/or nationalization of assets, confiscatory taxation, political instability, armed conflict and social instability as a result of religious, ethnic, socio-economic and/or political unrest. Some economies in this region are dependent on a range of commodities, and are strongly affected by international commodity prices and particularly vulnerable to price changes for these products. The market for securities in this region may also be directly influenced by the flow of international capital, and by the economic and market conditions of neighboring countries. Many Asia-Pacific economies have experienced rapid growth and industrialization, and there is no assurance that this growth rate will be maintained. Some Asia-Pacific economies are highly dependent on trade and economic conditions in other countries can impact these economies.

Europe Risk. The Economic and Monetary Union of the European Union (the “E.U.”) requires compliance with restrictions on inflation rates, deficits, interest rates, debt levels and fiscal and monetary controls, each of which may significantly affect every country in Europe. Decreasing imports or exports, changes in governmental or E.U. regulations on trade, changes in the exchange rate of the euro, the default or threat of default by an E.U. member country on its sovereign debt, and/or an economic recession in an E.U. member country may have a significant adverse effect on the economies of E.U. member countries and their trading partners. The European financial markets have recently experienced volatility and adverse trends due to concerns about economic downturns in, or rising government debt levels in several European countries, including Greece, Italy, Portugal and Spain. These events have adversely affected the exchange rate of the euro and may continue to significantly affect every country in Europe, including countries that do not use the euro.

An investment in issuers located or operating in Eastern Europe may subject the Fund to legal, regulatory, political, currency, security and economic risks specific to Eastern Europe. Economies of certain Eastern European countries rely heavily on the export of commodities, including oil, gas, and certain metals. As a result, such economies may be impacted by international commodity prices and are particularly vulnerable to global demand for these products. Geopolitical events, acts of terrorism, and other instability in certain Eastern European countries may cause uncertainty in their financial markets and adversely affect the performance of the issuers to which the Fund has exposure. The securities markets in some Eastern European countries are substantially smaller and less developed, with less government supervision and regulation of stock exchanges, and may be less liquid and more volatile than securities markets in the United States or Western European countries.

Other risks related to investing in securities of issuers located or operating in Eastern Europe include: delays in transaction settlements, the risk of relying on foreign sub-custodians, the risk that ownership of the Fund’s securities may become disputed, the absence of legal structures governing private and foreign investments and private property; the possibility of the loss of all or a substantial portion of the Fund’s assets invested in issuers located or operating in Eastern Europe as a result of expropriation; and certain national policies which may restrict the Fund’s investment opportunities, including, without limitation, restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

In June 2016, the United Kingdom voted in a referendum to leave the E.U. As a result of the referendum, S&P downgraded the United Kingdom’s credit rating from “AAA” to “AA” and the E.U.’s credit rating from “AA+” to “AA” in the days that followed the vote. Other credit ratings agencies have taken similar actions. It is expected that the United Kingdom will invoke article 50 of the Lisbon Treaty to withdraw from the EU by the end of March 2019, two years after the United Kingdom notified the European Council of the United Kingdom’s intention to withdraw. Withdrawal is expected to be followed by a transition period during which businesses and others prepare for the new post-Brexit rules to take effect on January 1, 2021. It is unclear how withdrawal negotiations will be conducted and what the potential consequences may be. In addition, it is possible that measures could be taken to revote on the issue of Brexit, or that portions of the United Kingdom could seek to separate and remain a part of the E.U. As a result of the political divisions within the United Kingdom and between the United Kingdom and the E.U. that the referendum vote has highlighted and the uncertain consequences of a Brexit, the economies of the United Kingdom and Europe as well as the broader global economy could be significantly impacted, which may result in increased volatility and illiquidity, and potentially lower economic growth on markets in the United Kingdom, Europe and globally that could potentially have an adverse effect on the value of a Fund’s investments.

Greece Risk. Recent geopolitical events in the European Union, and specifically in Greece, have destabilized Greece: on or about June 30, 2015, Greece failed to make a scheduled debt payment to its creditors, and the Greek government instituted a bank holiday and capital controls. During the bank holiday, the Athens Stock Exchange was closed and the Fund’s ability to trade Greek securities was limited. The duration and outcome of the current situation cannot be predicted, and it is possible that Greece may exit the European Monetary Union, which would likely result in the redenomination and devaluation of the Greek currency and increase the potential for Greece to default on its other outstanding debts.

These events have adversely affected, and are expected to continue to adversely affect, the value and liquidity of the Fund’s investments in Greek issuers and issuers in other European countries due to, among other things, their position as a creditor of Greece and the risk of financial contagion. These events may also lead to increased short-term market volatility and adverse long-term effects on global markets.

There is the possibility that Greece may exit the European Monetary Union, which would result in immediate devaluation of the Greek currency. If this were to occur, Greece would face significant risks related to the process of full currency redenomination as well as the resulting instability of Europe in general, which would have a severe adverse effect on the value of securities held by the Fund. If Greece opts to leave the European Monetary Union, the economic consequences could be severe for Greece and harmful to those around the world that hold Greek investments or are otherwise exposed to Greece’s economy. The impact of these actions, especially if they occur in a disorderly fashion, is not clear but could be significant and far-reaching. Any partial or complete dissolution of the European Monetary Union, or any increased uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Fund’s investments.

During the closure of any primary exchange on which the Fund’s securities trade, current market quotations will be unavailable and the Fund will fair value such securities pursuant to the Trust’s fair valuation procedures. Thus, if the Athens Stock Exchange closes, it is possible that, as a result, the market price of the Fund’s shares may significantly deviate from the Fund’s NAV.

In addition, the unavailability of current market quotations from the Athens Stock Exchange for the securities of Greek issuers in the Underlying Index and/or held by the Fund may affect: the calculation of the value of the Underlying Index and the calculation of the Fund’s Intraday Indicative Value. As a result, the Fund’s NAV may experience increased tracking error with respect to the Underlying Index.

These developments may lead to changes in the Underlying Index and the Index Provider may remove securities from the Underlying Index or implement caps on the securities of certain issuers that have been impacted by these developments. In such an event, it is expected that, to the extent possible, the Fund will rebalance its portfolio to bring it in line with the Underlying Index, as a result of any such changes, which may result in transaction costs and increased tracking error. However, capital controls may restrict the Fund’s ability to sell Greek securities and reinvest the proceeds.

Russia Risk. A portion of the Fund’s investments may be in Russian securities and instruments. As a result of recent events involving Ukraine and the Russian Federation, the United States, the European Union and other Western countries have imposed sanctions on certain Russian individuals and entities. The United States and other nations or international organizations may impose additional, broader economic sanctions or take other actions that may adversely affect Russian-related issuers in the future. These sanctions, any future sanctions or other actions, or even the threat of further sanctions or other actions, may negatively affect the value and liquidity of the Fund’s investments. For example, the Fund may be prohibited from investing in securities issued by companies subject to such sanctions. In addition, the sanctions may require the Fund to freeze its existing investments in Russian companies, prohibiting the Fund from buying, selling or otherwise transacting in these investments. Russia may undertake countermeasures or retaliatory actions which may further impair the value and liquidity of the Fund’s portfolio and potentially disrupt its operations.

For these or other reasons, the Fund may seek to suspend redemptions of Creation Units, including in the event that an emergency exists in which it is not reasonably practicable for the Fund to dispose of its securities or to determine its net asset value. The Fund could also, among other things, limit or suspend creations of Creation Units. During the period that creations or redemptions are affected, the Shares could trade at a significant premium or discount to their net asset value. In the case of a period during which creations are suspended, the Fund could experience substantial redemptions, which may cause the Fund to experience increased transaction costs and make greater taxable distributions to shareholders of the Fund. The Fund may also change its investment objective or principal investment strategies. The Fund may also have to liquidate all or a portion of its assets, which may be at unfavorable prices.

South America Risk. The economies and financial sectors of certain emerging markets countries are affected by the economies of South American countries, some of which have experienced high interest rates, economic volatility, inflation, currency devaluations, government defaults, high unemployment rates, and expropriation and/or nationalization of assets. In addition, commodities (such as oil, gas and minerals) represent a significant percentage of the region's exports and many economies in this region are particularly sensitive to fluctuations in commodity prices. Adverse economic events in one country may have a significant adverse effect on other countries in this region and on the financial sectors of emerging markets countries.

Hedging Risk. Options used by the Fund to reduce volatility may not perform as intended. There can be no assurance that the Fund’s option strategy will be effective. It may expose the Fund to losses, e.g. , option premiums, to which it would not have otherwise been exposed if it only invested in stocks. Further, the option strategy may not fully protect the Fund against declines in the value of its portfolio securities.

High Yield Securities Risk. Securities that are high yield, commonly referred to as “junk bonds,” are regarded as inherently speculative with respect to the capacity to pay interest and repay principal. High yield securities are subject to a greater risk of default and investments in them are inherently speculative. High yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher grade securities. The prices of high yield securities have been found to be less sensitive to interest rate changes than are more highly rated investments, but more sensitive to adverse economic downturns or individual corporate developments. Yields on high yield securities will fluctuate. If the issuer of high yield securities defaults, the Fund may incur additional expenses to seek recovery. The secondary markets in which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading markets could adversely affect the price at which the Fund could sell a particular high yield security when necessary to meet liquidity needs or in response to a specific economic event, such as a deterioration in the creditworthiness of the issuer. Adverse publicity and investor perceptions may decrease the values and liquidity of high yield securities.

Interest Rate Risk. The market value of fixed income securities, and financial instruments related to fixed income securities, will change in response to changes in interest rates. As interest rates rise, the value of certain fixed income securities is likely to decrease. Similarly, if interest rates decline, the value of fixed income securities is likely to increase. Longer maturity securities tend to be more sensitive to changes in interest rates and more volatile; and thus an Underlying Vehicle with a longer portfolio maturity generally is subject to greater interest rate risk. As of the date of this Prospectus, interest rates are near historic lows, but risks associated with rising interest rates are heightened given the Federal Reserve’s recent interest rate hikes, which could signal an end to the historically low interest rate environment. To the extent that rates increase substantially and/or rapidly, an Underlying Vehicle investing in fixed incomes securities, and the Fund, may be subject to significant losses.

International Closed-Market Trading Risk . Because the Fund’s investments may be traded in markets that are closed when the Exchange is open, there are likely to be deviations between the current pricing of an underlying investment and stale investment pricing ( i.e. , the last quote from its closed foreign market), resulting in premiums or discounts to NAV that may be greater than those experienced by other ETFs.

Investment Risk. As with all investments, an investment in the Fund is subject to investment risk. Investors in the Fund could lose money, including the possible loss of the entire principal amount of an investment, over short or long periods of time. An investment in the Fund is not a bank deposit and it is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

Large Capitalization Company Risk. Investments in large capitalization companies may go in and out of favor based on market and economic conditions and may underperform other market segments. Some large capitalization companies may be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes, and may not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion. As such, returns on investments in stocks of large capitalization companies could trail the returns on investments in stocks of small and mid-capitalization companies.

Leveraging Risk.   The Fund’s use of derivatives and other investment strategies may result in leverage. Leverage creates investment exposure to gains and losses in excess of the amounts invested by the Fund. The Fund will identify liquid assets on its books or otherwise cover transactions that may give rise to leverage to the extent required by applicable law. The Fund may have to liquidate assets to meet to satisfy obligations or coverage requirements that arise because of the use of leverage. Leverage could cause the Fund to be more volatile, resulting in larger gains or losses in response to changes in the values to which the Fund has leveraged exposure than if the Fund had made direct investments. Use of leverage involves special risks and is highly speculative. Leverage will magnify any losses, and such losses may be significant.

Liquidity Risk. Liquidity risk exists when a particular investment is difficult to purchase or sell. The Fund may invest in fixed income securities, derivatives, and/or other instruments that may be less liquid than other types of investments. The securities and instruments in which the Fund invests may not always be liquid. This could have a negative effect on the Fund’s ability to achieve its investment objective and may result in losses to Fund shareholders.

Derivatives. In certain circumstances, such as the disruption of the orderly markets for the securities in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of the Adviser. Markets for the securities in which the Fund invests may be disrupted by a number of events, including but not limited to economic crises, natural disasters, new legislation, or regulatory changes inside or outside of the U.S. For example, regulation limiting the ability of certain financial institutions to invest in certain securities would likely reduce the liquidity of those securities. These situations may prevent the Fund from limiting losses or realizing gains.

Fixed Income Securities. A significant, rapid rise in interest rates may result in a period of volatility and increased redemptions if Fund securities become illiquid and are forced to sell the illiquid securities at disadvantageous times or prices.

Management Risk. The Fund is actively managed and uses proprietary investment strategies and processes. There can be no guarantee that the Adviser’s judgments about the attractiveness, value and potential appreciation of particular investments and strategies for the Fund will be correct or produce the desired results and no guarantee that the Fund will achieve its investment objective or outperform other investment strategies over the short- or long-term market cycles. If the Adviser fails to accurately evaluate market risk or appropriately react to current and developing market conditions, the Fund’s share price may be adversely affected. Securities selected by Cambria may not perform as expected. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

Market Events Risk. Turbulence in the financial markets and reduced liquidity in equity, credit and fixed-income markets may negatively affect issuers worldwide, which could have an adverse effect on the Fund. Following the financial crisis that began in 2007, the Federal Reserve has attempted to stabilize the U.S. economy and support the U.S. economic recovery by keeping the federal funds rate at or near zero percent. When the Federal Reserve raises the federal funds rate, there is a risk that interest rates across the U.S. financial system will rise. These policy changes may expose markets to heightened volatility and may reduce liquidity for certain Fund investments, causing the value of the Fund’s investments and share price to decline. To the extent the Fund experiences high redemptions because of these policy changes, the Fund may experience increased portfolio turnover, which will increase the costs that the Fund incurs and may lower the Fund’s performance.

Momentum Investing Risk. The Fund employs a “momentum” style of investing that emphasizes investing in securities that have had higher recent price performance compared to other securities. This style of investing is subject to the risk that these securities may be more volatile than a broad cross-section of securities or that the returns on securities that have previously exhibited price momentum are less than returns on other styles of investing or the overall stock market. High momentum may also be a sign that the securities’ prices have peaked. Momentum can turn quickly and cause significant variation from other types of investments. The Fund may experience significant losses if momentum stops, turns or otherwise behaves differently than predicted.

Non-Diversification Risk. The Fund is non-diversified. As a non-diversified fund, the Fund will be subject to more investment risk and potential for volatility than a diversified fund because its portfolio may include only a limited number of issuers. These factors can have a negative effect on the value of the Fund’s Shares.

Options Risk. Options are subject to correlation risk because there may be an imperfect correlation between the prices of options and movements in the price of the underlying securities. Options may expire unexercised, causing the Fund to lose the premium paid for them. The success of the Fund’s investment in options depends upon many factors, such as the price of the options which is a function of various factors that may change rapidly over time. If a counterparty defaults, the Fund’s only recourse will be to pursue contractual remedies against the counterparty, and the Fund may be unsuccessful in its pursuit. The Fund thus assumes the risk that it may be delayed in or prevented from obtaining payments owed to it pursuant to an over-the-counter options transaction.

Core Equity ETF. Exchange traded index options give the holder of the option the right to buy (or to sell) a position in an index of securities to the writer of the option, at a certain price. Writing index call options reduces the Fund’s ability to profit from increases in the value of the Fund’s equity portfolio, and purchasing put options may result in the Fund’s loss of premiums paid in the event that the put options expire unexercised. To the extent that the Fund reduces its put option holdings relative to the number of call options sold by the Fund, the Fund’s ability to mitigate losses in the event of a market decline will be reduced.

Covered Call Strategy ETF. Exchange traded index options give the holder of the option the right to buy (or to sell) a position in an index of securities to the writer of the option, at a certain price. Writing index call options reduces the Fund’s ability to profit from increases in the value of the Fund’s equity portfolio. When writing call option on an Underlying Vehicle, the Fund receives a premium; however, the premium may not be enough to offset a loss incurred by the Fund if the price of the Underlying Vehicle is above the strike price by an amount equal to or greater than the premium. The Fund’s option strategy is designed to provide the Fund with income by taking in options premiums, but it is not designed to mitigate losses to the Fund in the event of a market decline.

Passive Investment Risk. The Fund is managed with a passive investment strategy, attempting to track the performance of the Underlying Index. This differs from an actively managed fund, which typically seeks to outperform a benchmark index. As a result, the Fund may hold components of the Underlying Index regardless of the current or projected performance of a specific security or a particular industry or market sector. Maintaining investments in securities regardless of market conditions or the performance of individual securities could cause the Fund’s return to be lower than if the Fund employed an active strategy. The Underlying Index reflects a limited number of securities, may not deliver positive returns, and may not perform as well as other types of investments.

Portfolio Turnover Risk. The   Fund’s investment strategy may from time to time result in higher portfolio turnover rates. This may increase the Fund’s brokerage commission costs. The performance of the Fund could be negatively impacted by the increased brokerage commission costs incurred by the Fund. Rapid portfolio turnover may also result in a substantial amount of distributions from the Fund to be taxed as ordinary income, which may limit the tax efficiency of the Fund.

Precious Metals Risk. Prices of precious metal-related securities are often very volatile. The production and sale of precious metals, such as gold, by governments or central banks or other larger holders can be affected by various economic, financial, social and political factors, which may be unpredictable and may have a significant impact on the prices of precious metals. Other factors that may affect the prices of precious metals and securities related to them include changes in inflation, the outlook for inflation and changes in industrial and commercial demand for precious metals. The Fund may incur higher custody and transaction costs for precious metals than for securities.

Premium-Discount Risk. The Shares may trade above or below their NAV. The NAV of the Fund will generally fluctuate with changes in the market value of the Fund’s holdings. The market prices of Shares, however, will generally fluctuate in accordance with changes in NAV as well as the relative supply of, and demand for, Shares on the Exchange. The trading price of Shares may deviate significantly from NAV during periods of market volatility. Cambria cannot predict whether Shares will trade below, at or above their NAV. Price differences may be due, in large part, to the fact that supply and demand forces at work in the secondary trading market for Shares will be closely related to, but not identical to, the same forces influencing the prices of the securities held by the Fund. However, given that Shares can be purchased and redeemed in large blocks of Shares, called Creation Units (unlike shares of closed-end funds, which frequently trade at appreciable discounts from, and sometimes at premiums to, their NAV), and the Fund’s portfolio holdings are fully disclosed on a daily basis, Cambria   believes that large discounts or premiums to the NAV of Shares should not be sustained, but that may not be the case.

Quantitative Security Selection Risk . Data for some issuers, particularly for emerging market issuers, may be less available and/or less current than data for issuers in other markets. With respect to the Active Funds, Cambria uses quantitative techniques to generate investment decisions, and with respect to the Index Funds, the Underlying Index uses quantitative techniques to determine whether securities should be included in the Underlying Index. Cambria and the Underlying Index, respectively, may not perform as intended if it relies on erroneous or outdated data from one or more third parties. Errors in data used in the quantitative model may occur from time to time and may not be identified and/or corrected before having an adverse impact on the Fund and its shareholders. Securities selected using quantitative analysis can perform differently from the market as a whole as a result of the characteristics used in the analysis, the weight placed on each characteristic, and changes in the characteristic’s historical trends. The factors used in such analyses may not be predictive of a security’s value and its effectiveness can change over time. These changes may not be adequately reflected in the quantitative model.

Real Estate Investments Risk. The Fund is subject to the risks related to investments in real estate, including declines in the real estate market, decreases in property revenues, increases in interest rates, increases in property taxes and operating expenses, legal and regulatory changes, a lack of credit or capital, defaults by borrowers or tenants, environmental problems and natural disasters.

REIT Risk. In addition to the risks associated with the real estate industry, REITs are subject to additional risks, including those related to adverse governmental actions and the potential failure to qualify for tax-free pass through of income and exemption from registration as an investment company. REITs are dependent upon specialized management skills and may invest in relatively few properties, a small geographic area or a small number of property types. As a result, investments in REITs may be volatile. REITs are pooled investment vehicles with their own fees and expenses and the Fund will indirectly bear a proportionate share of those fees and expenses.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market will generally pay brokerage commissions or other charges imposed by brokers as determined by that broker. Brokerage commissions are often a fixed amount and may be a significant proportional cost for investors seeking to buy or sell relatively small amounts of Shares. In addition, secondary market investors will also incur the cost of the difference between the price that an investor is willing to pay for Shares (the “bid” price) and the price at which an investor is willing to sell Shares (the “ask” price). This difference in bid and ask prices is often referred to as the “spread” or “bid/ask spread.” The bid/ask spread varies over time for Shares based on trading volume and market liquidity, and is generally lower if the Fund’s Shares have more trading volume and market liquidity and higher if the Fund’s Shares have little trading volume and market liquidity. Further, increased market volatility may cause increased bid/ask spreads.

Although the Shares are listed on the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable. Further, trading in Shares on the Exchange is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange “circuit breaker” rules. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged.

Short Sale Risk. If a security is sold short and subsequently has to be bought back at a higher price, the Fund will realize a loss on the transaction. The amount of loss on a short sale is potentially unlimited because there is no limit on the price a shorted security might attain (as compared to a long position, where the maximum loss is the amount invested). The use of short sales may increase the Fund’s exposure to the market, and may increase losses and the volatility of returns.

Small and Medium Capitalization Company Risk . Investing in securities of small and medium capitalization companies involves greater risk than customarily is associated with investing in larger, more established companies. These companies’ securities may be more volatile and less liquid than those of more established companies. These securities may have returns that vary, sometimes significantly, from the overall securities market. Small and medium capitalization companies are sometimes more dependent on key personnel or limited product lines than larger, more diversified companies. Often, small and medium capitalization companies and the industries in which they focus are still evolving and, as a result, they may be more sensitive to changing market conditions.

Sovereign Debt Securities Risk. Investments in sovereign and quasi-sovereign debt obligations involve special risks not present in corporate debt obligations. The issuer of the sovereign debt or the governmental authorities that control the repayment of the debt may be unable or unwilling to repay principal or interest when due, and the Fund may have limited recourse in the event of a default. During periods of economic uncertainty, the market prices of sovereign debt, and the Fund’s net asset value, may be more volatile than prices of U.S. debt obligations. In the past, certain non-U.S. markets have encountered difficulties in servicing their debt obligations, withheld payments of principal and interest and declared moratoria on the payment of principal and interest on their sovereign debts. These risks increase for lower-rated and high yield debt securities, as discussed in this Prospectus.

Swaps Contract Risk. Each swap exposes the Fund to counterparty risk when a counterparty to a financial instrument entered into by the Fund may become bankrupt or otherwise fail to perform its obligations due to financial difficulties. As a result, the Fund may experience delays in or be prevented from obtaining payments owed to it pursuant to a swap contract.

Tax Risk. In order to qualify for treatment as a regulated investment company for federal income tax purposes, the Fund must among other requirements, derive at least 90% of its gross income for each taxable year from “qualifying income.” “Qualifying Income” for a regulated investment company currently includes gains from currencies, however, the U.S. Treasury Department has authority to issue regulations that would exclude such foreign currency gains from “qualifying income” if such gains are not directly related to the Fund’s business of investing in stock or securities and could limit the Fund’s ability to qualify as a regulated investment company. If in any year the Fund were to fail to qualify as a regulated investment company, it would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level.

Tracking Error Risk. Tracking error is the   difference between the Fund’s performance from that of the Underlying Index. This may occur due to an imperfect correlation between the Fund’s holdings and those comprising the Underlying Index, pricing differences, the Fund’s holding of cash, differences in the timing of dividend accruals, changes to the Underlying Index, or the need to meet regulatory requirements. If the Fund is small, it may experience greater tracking error to its Underlying Index or it could ultimately liquidate. This risk is heightened during times of increased market volatility or other unusual market conditions. If the Fund uses a representative sampling strategy to track the Underlying Index, such a strategy may produce greater tracking error than if the Fund employed a full replication strategy.

Underlying Vehicle Counterparty and Leverage Risk. The Fund may be exposed to additional risks due to the nature of the investment programs of the Underlying Vehicles. The Underlying Vehicles may engage in investment transactions or other contracts with third parties ( i.e. , “counterparties”). They bear the risk that the counterparty to these contracts becomes bankrupt, defaults on its obligations or otherwise fails to honor its obligations and may experience significant delays in obtaining any recovery in a bankruptcy or other reorganization proceeding involving the counterparty. If a counterparty defaults on its payment obligations, the Underlying Vehicle, and therefore the Fund, will lose money and the value of an investment in Fund Shares may decrease. Derivatives used by the Underlying Vehicles may include leverage, allowing them to obtain the right to a return on stipulated capital that exceeds the amount paid or invested. Although Underlying Vehicles registered under the Investment Company Act of 1940 (the “Investment Company Act”) will segregate or earmark liquid assets to cover the market value of its obligations under certain derivatives, the amount will be limited to the current value of the obligations to the counterparty, and will not prevent losses greater than the value of those obligations, and Underlying Vehicles not so registered may not have such cover obligations. The use of derivatives could cause the Fund to be more volatile, resulting in larger gains or losses in response to changes in the values of the securities subject to the derivative than direct investments. Use of leverage involves special risks and is speculative and could magnify any losses, and such losses may be significant.

Value Investment Risk. Value investments are subject to the risk that their intrinsic value may never be realized by the market. This may result in the value stocks’ prices remaining undervalued for extended periods of time. The Fund’s performance also may be affected adversely if value stocks become unpopular with or lose favor among investors. Different investment styles tend to shift in and out of favor, depending on market conditions and investor sentiment. The Fund’s value style could cause it to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

Additional Non-P RINCIPAL Risk Information

Authorized Participants , Market Makers and Liquidity Providers Concentration Risk. Each Fund has a limited number of financial institutions that may act as Authorized Participants. To the extent they cannot or are otherwise unwilling to engage in creation and redemption transactions with the Fund and no other Authorized Participant steps in, shares of the Fund may trade like closed-end fund shares at a significant discount to net asset value and may face delisting from the Exchange. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions, shares of the Fund may trade at a material discount to net asset value and face delisting.

Cash and Cash Equivalents Holdings Risk. Each Fund may invest in cash and cash equivalents for indefinite periods of time when Cambria determines the prevailing market environment warrants doing so. When a Fund holds cash positions, it may lose opportunities to participate in market appreciation, which may result in lower returns than if the Fund had remained fully invested in the market. This is particularly true when the market for other investments in which the Fund may invest is rapidly rising. Furthermore, cash and cash equivalents may generate minimal or no income and could negatively impact the Fund’s performance and ability to achieve its investment objective.

Clearing Broker Risk. The failure or bankruptcy of a Fund’s clearing broker could result in a substantial loss of Fund assets. Under current Commodity Futures Trading Commission (“CFTC”) regulations, a clearing broker maintains customers’ assets in a bulk segregated account. If a clearing broker fails to do so, or is unable to satisfy a substantial deficit in a customer account, its other customers may be subject to risk of loss of their funds in the event of that clearing broker’s bankruptcy. In that event, the clearing broker’s customers, such as the Funds, are entitled to recover, even in respect of property specifically traceable to them, only a proportional share of all property available for distribution to all of that clearing broker’s customers.

Operational Risk. Each Fund and its service providers, including Cambria, the Fund’s administrator, custodian, and transfer agent, may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures. Any such disruptions may have an adverse impact on the Fund. Although the Fund and its service providers seek to reduce these operational risks through their internal controls and processes, it may not be possible to identify and develop policies and controls to address all such risks.
