Investment Objective

The Salt truBeta^TM High Exposure ETF (the “Fund”) seeks to track the performance, before fees and expenses, of the Salt truBeta^TM High Exposure Index (the “Index”).

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund (“Shares”). This table and the example below do not include the brokerage commissions that investors may pay on their purchases and sales of Shares.

Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Management Fees	0.50%
Distribution and/or Service (12b-1) Fees	0.00%
Other Expenses^*	0.00%
Total Annual Fund Operating Expenses	0.50%

* Estimated for the current fiscal year.

Expense Example

This 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 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years
$51	$160

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when 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 is newly organized, portfolio turnover information is not yet available.

Principal Investment Strategy

The Fund uses a “passive management” (or indexing) approach to track the performance, before fees and expenses, of the Index. The Index was developed in 2017 by Salt Financial LLC, the Fund’s investment adviser and index provider (the “Adviser”), and uses an objective, rules-based methodology to measure the performance of an equal-weighted portfolio of approximately 100 large- and mid-capitalization U.S.-listed stocks with the highest forecasted systematic risk relative to the market (known as “beta”).

Salt truBeta^TM High Exposure Index

Construction of the Index begins with the constituents of the Solactive US Large & Mid Cap Index (the “Equity Universe”), generally the 1,000 largest U.S.-listed common stocks and real estate investment trusts (“REITs”). Companies in the Equity Universe are then screened to keep only the 500 stocks with the highest average daily traded value over the past 30 days. Those 500 stocks are then analyzed using a proprietary algorithm developed by the Adviser to calculate each stock’s truBeta^TM forecast, i.e., its projected beta for the subsequent quarter, and to eliminate stocks whose performance is weakly correlated with the broader U.S. equity market (the remaining securities are referred to as the “Index Universe”). A stock’s truBeta forecast is calculated using a machine learning process (i.e., a quantitative model that is automatically adjusted based on past results to improve accuracy) that compares the stock’s historical long-, medium-, and short-term risk and returns to those of the broader U.S. equity market (using the SPDR S&P 500 ETF (SPY) as a market proxy). A stock with a truBeta of 1.00 would be expected to demonstrate a risk and return profile identical to that of the broader U.S. equity market. A stock with a truBeta of more than 1.00 would be expected to be more volatile than the broader U.S. equity market and consequently, exhibit outsized reactions to market events (i.e., outperform the market in a rising market and underperform the market in a declining market).

At the time of each rebalance of the Index, the Index is constructed of the 100 stocks in the Index Universe with the highest truBeta, equally weighted and subject to a maximum 30% of the number of constituents in the Index being from a single sector. If more than 30% of the constituents would be from a single sector, the stock with the lowest truBeta score in such sector will be removed from the Index and replaced with the stock with the next highest truBeta forecast not already included in the Index. This process is repeated until each sector complies with the sector concentration constraint.

As of March 12, 2018, the Index had an average truBeta of approximately 1.27. Consequently, the Index is expected to be significantly more volatile than the broader U.S. equity market.

The Index is rebalanced quarterly on the third Friday of March, June, September, and December (each, an “Effective Date”) based on truBeta forecasts utilizing data as of five business days prior to the Effective Date of the applicable rebalance month. Each rebalance of the Index utilizes constituent prices at the close of trading five business days prior to the Effective Date for weighting purposes.

The Fund’s Investment Strategy

The Fund attempts to invest all, or substantially all, of its assets in the component securities that make up the Index. Under normal circumstances, at least 80% of the Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Index. The Adviser expects that, over time, the correlation between the Fund’s performance and that of the Index, before fees and expenses, will be 95% or better.

The Fund will generally use a “replication” strategy to achieve its investment objective, meaning it generally will invest in all of the component securities of the Index in approximately the same proportion as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).

The Fund generally may invest up to 20% of its total assets (exclusive of any collateral held from securities lending) in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).

To the extent the Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. The Fund is non-diversified and therefore may invest a larger percentage of its assets in the securities of a single issuer or small number of issuers than diversified funds.

Principal Investment Risks

You can lose money on your investment in the Fund. The Fund is subject to the risks described below. Some or all of these risks may adversely affect the Fund’s net asset value per share (“NAV”), trading price, yield, total return and/or ability to meet its objectives. For more information about the risks of investing in the Fund, see the section in the Fund’s Prospectus titled “Additional Information About the Fund—Principal Investment Risks.”

Equity Market Risk. The equity securities held in the Fund’s portfolio may experience sudden, unpredictable drops in value or long periods of decline in value. This may occur because of factors that affect securities markets generally or factors affecting specific issuers, industries, or sectors in which the Fund invests. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

Index Risk. Because the Index includes the securities in the Index Universe with the highest truBeta, the Index, and consequently the Fund, can be expected to be significantly more volatile than the broader U.S. equity market. As a result, the Index, and consequently the Fund, may significantly underperform the broader U.S. equity market over short or long periods of time. Additionally, the calculation of a security’s truBeta is based on past performance and may not be indicative of the extent to which the security will demonstrate a similar risk and return profile relative to the broader U.S. equity market in the future. Consequently, there can be no guarantee that the Index, or the Fund, will perform in the future the way the average truBeta suggests it would.

Models and Data Risk. The composition of the Index is heavily dependent on a proprietary quantitative model as well as information and data supplied by third parties (“Models and Data”). When Models and Data prove to be incorrect or incomplete, any decisions made in reliance thereon may lead to the inclusion or exclusion of securities from the Index universe that would have been excluded or included had the Models and Data been correct and complete. If the composition of the Index reflects such errors, the Fund’s portfolio can be expected to reflect the errors, too.

·	New Fund Risk. The Fund is a recently organized, non-diversified management investment company with no operating history. As a result, prospective investors have no track record or history on which to base their investment decision.

·	New Index Provider Risk. The Index was created by and is owned and maintained by the Adviser, which has not previously been an index provider or investment adviser for a registered fund, which may create additional risks for investing in the Fund.

Non-Diversification Risk. The Fund is deemed non-diversified and may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. As a result, the Fund may be more exposed to the risks associated with and developments affecting an individual issuer or a smaller number of issuers than a fund that invests more widely. This may increase the Fund’s volatility and cause the performance of a relatively smaller number of issuers to have a greater impact on the Fund’s performance.

Passive Investment Risk. The Fund is not actively managed, and the Fund’s adviser would not sell shares of an equity security due to current or projected underperformance of a security, industry, or sector, unless that security is removed from the Index or the selling of shares of that security is otherwise required upon a reconstitution of the Index in accordance with the Index methodology.

REIT Investment Risk. Investments in REITs involve unique risks. REITs may have limited financial resources, may trade less frequently and in limited volume, and may be more volatile than other securities. In addition, to the extent the Fund holds interests in REITs, it is expected that investors in the Fund will bear two layers of asset-based management fees and expenses (directly at the Fund level and indirectly at the REIT level). The risks of investing in REITs include certain risks associated with the direct ownership of real estate and the real estate industry in general. These include risks related to general, regional and local economic conditions; fluctuations in interest rates and property tax rates; shifts in zoning laws, environmental regulations and other governmental action such as the exercise of eminent domain; cash flow dependency; increased operating expenses; lack of availability of mortgage funds; losses due to natural disasters; overbuilding; losses due to casualty or condemnation; changes in property values and rental rates; and other factors.

In addition to these risks, residential/diversified REITs and commercial equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while mortgage REITs may be affected by the quality of any credit extended. Further, REITs are dependent upon management skills and generally may not be diversified. REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Internal Revenue Code of 1986, or to maintain their exemptions from registration under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund expects that dividends received from a REIT and distributed to Fund shareholders generally will be taxable to the shareholder as ordinary income. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

·	Sector Risk. To the extent the Fund invests more heavily in particular sectors of the economy, its performance will be especially sensitive to developments that significantly affect those sectors.

Energy Sector Risk. The energy sector is comprised of energy, industrial, infrastructure, and logistics companies, and will therefore be susceptible to adverse economic, environmental, business, regulatory, or other occurrences affecting that sector. The energy sector has historically experienced substantial price volatility. At times, the performance of these investments may lag the performance of other sectors or the market as a whole. Companies operating in the energy sector are subject to specific risks, including, among others, fluctuations in commodity prices; reduced consumer demand for commodities such as oil, natural gas, or petroleum products; reduced availability of natural gas or other commodities for transporting, processing, storing, or delivering; slowdowns in new construction; extreme weather or other natural disasters; and threats of attack by terrorists on energy assets. Additionally, energy sector companies are subject to substantial government regulation and changes in the regulatory environment for energy companies may adversely impact their profitability. Over time, depletion of natural gas reserves and other energy reserves may also affect the profitability of energy companies.

Financial Sector Risk. This sector can be significantly affected by changes in interest rates, government regulation, the rate of defaults on corporate, consumer and government debt, the availability and cost of capital, and fallout from the housing and sub-prime mortgage crisis. Insurance companies, in particular, may be significantly affected by changes in interest rates, catastrophic events, price and market competition, the imposition of premium rate caps, or other changes in government regulation or tax law and/or rate regulation, which may have an adverse impact on their profitability. 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. In recent years, cyber attacks and technology malfunctions and failures have become increasingly frequent in this sector and have caused significant losses.

Information Technology Sector Risk. Market or economic factors impacting information technology companies and companies that rely heavily on technological advances could have a significant effect on the value of the Fund’s investments. The value of stocks of information technology companies and companies that rely heavily on technology is particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition, both domestically and internationally, including competition from foreign competitors with lower production costs. Stocks of information technology companies and companies that rely heavily on technology, especially those of smaller, less-seasoned companies, tend to be more volatile than the overall market. Information technology companies are heavily dependent on patent and intellectual property rights, the loss or impairment of which may adversely affect profitability.

Shares May Trade at Prices Other Than NAV. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although it is expected that the market price of Shares will approximate the Fund’s NAV, there may be times when the market price of Shares is more than the NAV intra-day (premium) or less than the NAV intra-day (discount) due to supply and demand of Shares or during periods of market volatility. This risk is heightened in times of market volatility, periods of steep market declines, and periods when there is limited trading activity for Shares in the secondary market, in which case such premiums or discounts may be significant.

Tracking Error Risk. As with all index funds, the performance of the Fund and its Index may differ from each other for a variety of reasons. For example, the Fund incurs operating expenses and portfolio transaction costs not incurred by the Index. In addition, the Fund may not be fully invested in the securities of the Index at all times or may hold securities not included in the Index.

Purchase and Sale of Shares

Shares are listed on a national securities exchange, such as Cboe BZX Exchange, Inc. (the “Exchange”), and most investors will buy and sell Shares through brokers at market prices, rather than NAV. Because Shares trade at market prices rather than NAV, Shares may trade at a price greater than NAV (premium) or less than NAV (discount).

The Fund issues and redeems Shares at NAV only in large blocks known as “Creation Units,” which only Authorized Participants (“APs”) (typically, broker-dealers) may purchase or redeem. Creation Units generally consist of 25,000 Shares, though this may change from time to time. The Fund generally issues and redeems Creation Units in exchange for a portfolio of securities closely approximating the holdings of the Fund (the “Deposit Securities”) and/or a designated amount of U.S. cash.

Tax Information

Fund distributions are generally taxable as ordinary income, qualified dividend income, or capital gains (or a combination), unless your investment is in an individual retirement account (“IRA”) or other tax-advantaged account. Distributions on investments made through tax-deferred arrangements may be taxed later upon withdrawal of assets from those accounts.

Financial Intermediary Compensation

If you purchase Shares through a broker-dealer or other financial intermediary (such as a bank) (an “Intermediary”), the Adviser or its affiliates may pay Intermediaries for certain activities related to the Fund, including participation in activities that are designed to make Intermediaries more knowledgeable about exchange traded products, including the Fund, or for other activities, such as marketing, educational training or other initiatives related to the sale or promotion of Shares. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Any such arrangements do not result in increased Fund expenses. Ask your salesperson or visit the Intermediary’s website for more information.
