FUND SUMMARY

Cambria Global Momentum ETF

Investment Objective

Cambria Global Momentum ETF (the “Fund”) seeks to preserve and grow capital from investments in the U.S. and foreign equity, fixed income, commodity and currency markets, independent of market direction.

Fees and Expenses

This table describes the fees and expenses that you may pay if you buy and hold Shares of the Fund. You may also pay brokerage commissions on the purchase and sale of Shares, which are not reflected in the table.

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

Management Fee:	0.59%
Distribution and/or Service (12b-1) fees:*	0.00%
Acquired Fund Fees and Expenses:**	0.35%
Other Expenses:**	0.00%
Total Annual Fund Operating Expenses:**	0.94%

* Pursuant to a 12b-1 Distribution and Service Plan, the Fund may bear a 12b-1 fee not to exceed 0.25% per annum of the Fund’s average daily net assets. However, no such fee is currently paid by the Fund, and the Board of Trustees has not currently approved the commencement of any payments under the plan.

** Based on estimated amounts for the current fiscal year.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 for the time periods indicated and then redeem all of your Shares at the end of those periods. The example also assumes that the Fund provides a return of 5% a year and that operating expenses remain the same. The example does not reflect any brokerage commissions that you may pay on purchases and sales of Shares. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

One Year:	Three Years:
$96	$300

Portfolio Turnover

The Fund may pay transaction costs, including commissions when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. Because the Fund has not yet commenced operations, it does not have a portfolio turnover rate to provide.

Principal Investment Strategies

The Fund is considered a “fund of funds” that seeks to achieve its investment objective by primarily investing in other exchange-traded funds (the “ETFs”) and other exchange traded products (“ETPs”) including, but not limited to, exchange-traded notes (“ETNs”), exchange traded currency trusts, closed-end funds, and real estate investment trusts (together, “Underlying Vehicles”) that offer diversified exposure, including inverse exposure, to global regions (including emerging markets), countries, styles (i.e., market capitalization, value, growth, etc.) and sectors. The Fund will invest in Underlying Vehicles spanning all the major world asset and instrument classes including equities, bonds (including high yield bonds, which are commonly referred to as “junk bonds”), real estate, derivatives, commodities, and currencies.   The Fund’s investment adviser, Cambria Investment Management, L.P. (“Cambria”) will actively manage the Fund’s portfolio utilizing a quantitative strategy with risk management controls in an attempt to protect capital. Cambria’s model combines momentum and trend factors to select Underlying Vehicles for the Fund. Quantitative screens exclude foreign issuers whose securities are highly restricted or illegal for U.S. persons to own, including due to the imposition of sanctions by the U.S. Government. The Fund looks to allocate to the top-performing assets based on absolute and relative momentum, typically measured over periods of less than two years.   Through Underlying Vehicles, the Fund may have exposure to companies in any industry and of any market capitalization. In addition to Underlying Vehicles, the Fund may invest up to 20% of its net assets in directly in other securities and financial instruments, including futures, cash and cash equivalents. Under normal market conditions, the Fund expects to invest at least 40% of its net assets in securities of issuers located in at least three different countries (including the United States).   The Fund may sell a security when Cambria believes that the security is overvalued or better investment opportunities are available, to invest in cash and cash equivalents, or to meet redemptions. Cambria expects to rebalance to target allocations monthly. As a result, the Fund may experience high portfolio turnover. •     ETFs are registered investment companies whose shares are exchange-traded and give investors a proportional interest in the pool of securities and other assets held by the ETF.   •     ETPs are exchange-traded equity securities whose value derives from an underlying asset or portfolio of assets, which may correlate to a benchmark, such as a commodity, currency, interest rate or index. ETFs are one type of ETP.   •     ETNs are unsecured and unsubordinated debt securities whose value derives, in part, from an underlying asset or benchmark and, in part, from the credit quality of the issuer.  

Principal Risks

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.

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.

3

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.

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. Investments that provide exposure to emerging markets, companies or currencies involve Foreign Investment Risk and potentially additional risks. 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 different settlement and trading practices. Each of these factors may make the Fund more volatile and adversely affect the price for Shares.

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.

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.

Foreign Investment Risk. Returns on investments in foreign securities could be more volatile than, or trail the returns on, investments in U.S. securities. Investments in or exposures to foreign securities are subject to special risks, including due to differences in information available about issuers of securities and investor protection standards applicable in other jurisdictions; political, diplomatic and economic risks; and foreign market and trading risks, including the costs of trading and settlement in foreign jurisdictions.

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, and financial instruments related to 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. Longer maturity securities tend to be more sensitive to changes in interest rates and more volatile; and thus a Fund with a longer portfolio maturity generally is subject to greater interest rate risk. Given the historically low interest rate environment, risks associated with rising rates are heightened.

4

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. Therefore, you may lose money by investing in the Fund.

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.

Management Risk. The Fund is actively managed using proprietary investment strategies and processes. There can be no guarantee that these strategies and processes will produce the intended results and no guarantee that the Fund will achieve its investment objective. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

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 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 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 or below 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. The trading price of Shares may deviate significantly from NAV during periods of market volatility.

Quantitative Security Selection Risk. Cambria uses quantitative techniques to generate investment decisions and its processes and stock selection can be adversely affected if it relies on erroneous or outdated data. In addition, the quantitative model may be flawed, and factors that affect a security’s value can change over time and these changes may not be reflected in the quantitative model.

Real Estate Risk. The real estate industry is particularly sensitive to economic downturns. The value of securities of issuers in the real estate industry, including real estate investment trusts (“REITs”), can be affected by changes in real estate values and rental income, property taxes, interest rates, tax and regulatory requirements, and the management skill and creditworthiness of the issuer. In addition, the value of a REIT or similar REIT-like entity can depend on the structure of and cash flow generated by the REIT, and REITs may not have diversified holdings. Because REITs are pooled investment vehicles that have expenses of their own, the Fund will indirectly bear its proportionate share of those expenses.

Secondary Market Trading Risk. Investors buying or selling Shares in the secondary market will pay brokerage commissions or other charges imposed by brokers as determined by that broker. 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.

5

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.

Performance

The Fund has not commenced operations as of the date of this Prospectus. Performance information will be available in the Prospectus after the Fund has been in operation for one full calendar year. When provided, the information will provide some indication of the risks of investing in the Fund by showing how the Fund’s average annual returns compare with a broad measure of market performance. Past performance does not necessarily indicate how the Fund will perform in the future.

Investment Adviser

Cambria Investment Management, L.P. (“Cambria” or the “Investment Adviser”) serves as the investment adviser of the Fund.

Portfolio Managers

Mebane T. Faber and Eric W. Richardson are the portfolio managers for the Fund and have managed the Fund since its inception in 2014.

Purchase and Sale of Fund Shares

The Fund issues and redeems Shares on a continuous basis only in large blocks of Shares, typically 50,000 Shares, called “Creation Units.” Creation Units are issued and redeemed in-kind for securities and/or for cash. Individual Shares may only be purchased and sold in secondary market transactions through brokers. Once created, individual Shares generally trade in the secondary market at market prices that change throughout the day. Market prices of Shares may be greater or less than their NAV.

Tax Information

Distributions you receive from the Fund are generally taxable to you as ordinary income for federal income tax purposes, except that distributions will be taxed to you at long-term capital gain rates to the extent reported by the Fund as “capital gain dividends” or “qualified dividend income,” and may also be subject to state or local taxes. Fund distributions may not be taxable to you if you are investing through a tax-advantaged retirement plan account or are a tax-exempt investor, although you may be taxed on withdrawals from your tax-advantaged account.

Purchases Through Broker-Dealers and Other Financial Intermediaries

If you purchase Shares through a broker-dealer or other financial intermediary, the Fund and its related companies may pay the intermediary for the sale of Shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend Shares over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
