Investment Objective

The American Customer Satisfaction Core Alpha ETF (the “Fund”) seeks to track the performance, before fees and expenses, of the American Customer Satisfaction Investable 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	0.65%
Distribution and/or Service (12b-1) Fees	0.00%
Other Expenses*	0.00%
Total Annual Fund Operating Expenses	0.65%

^* 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
$66	$208

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 is based on a proprietary methodology developed by the Fund’s investment adviser and index provider (the “Adviser”), in partnership with the American Customer Satisfaction Index, LLC, an affiliate of the Adviser and owner/publisher of the leading national cross-industry measure of customer satisfaction (the “Customer Satisfaction Data”). Calculation of the Customer Satisfaction Data incorporates surveys of more than 100,000 household customers each year to identify trends in customer satisfaction and provide benchmarking insights for companies, industry trade associations, and government agencies.

American Customer Satisfaction Investable Index

The Index uses an objective, rules-based methodology to measure the performance of (i) large capitalization U.S.-listed companies whose customers have been surveyed and who have been assigned a customer satisfaction score as part of the Customer Satisfaction Data (collectively, “ACSI Companies”) and (ii) U.S. sector-specific exchange-traded funds (“ETFs”) used by the Index to supplement its exposure to sectors for which there are too few ACSI Companies to achieve the target sector weights at the time of each rebalance. The Index is sector-weighted to reflect the overall U.S. large cap market, and security-weighted based on the Customer Satisfaction Data, subject to the constraints described below.

Construction of the Index begins with over 350 ACSI Companies across 43 industries and 10 economic sectors. The initial universe is then screened to eliminate companies whose stock is not principally listed on a U.S. exchange or does not meet minimum liquidity requirements, or for which the Customer Satisfaction Data is statistically insignificant. The remaining companies are included in the Index (the “Index Companies”).

At the time of each rebalance of the Index, the weight of each Index Company within a sector is based on its ACSI Score (described below) in proportion to the other ACSI Companies, subject to a maximum of 5%. Additionally, any Index Company with an ACSI Score in the 3^rd quartile of ACSI Scores for the applicable sector will be subject to a maximum weight of 3%, and any Index Company with an ACSI Score in the 4^th (bottom) quartile of ACSI Scores for the applicable sector will be subject to a maximum weight of 1%. Unallocated Index weight resulting from such constraints is re-allocated equally to the remaining companies in the applicable sector, subject to the above constraints.

A company’s ACSI Score is calculated by utilizing a proprietary model to evaluate customers’ Customer Satisfaction Data based on questions that measure the following facets of satisfaction with a product or service:

Customer   Expectations	Customer expectations is a measure of the customer’s anticipation of the quality of a company’s products or services. Expectations represent both prior consumption experience, which includes some nonexperiential information like advertising and word-of-mouth, and a forecast of the company’s ability to deliver quality in the future.
Perceived Quality	Perceived quality is a measure of the customer’s evaluation via recent consumption experience of the quality of a company’s products or services. Quality is measured in terms of both customization, which is the degree to which a product or service meets the customer’s individual needs, and reliability, which is the frequency with which things go wrong with the product or service.
Perceived Value	Perceived value is a measure of quality relative to price paid. Although price (value for money) is often very important to the customer’s first purchase, it usually has a somewhat smaller impact on satisfaction for repeat purchases.

At the time of each rebalance of the Index, the Index weight is allocated to each economic sector based on the aggregate number of the Index Companies in each sector relative to that of each other sector, provided that such weights will be adjusted upward or downward if necessary to be within 10% of the weight of such sector in the overall U.S. large cap market. For example, if the unadjusted Index weight for a sector is 9%, but the weight of the sector in the overall U.S. large cap market is 25%, the Index sector weight will be increased by 6% to 15% in total. If the unadjusted Index weight for a sector is 39%, but the weight of the sector in the overall U.S. large cap market is 25%, the Index sector weight will be decreased by 4% to 35% in total. Unallocated Index weight resulting from such downward adjustments is re-allocated first equally to sectors requiring an upward weight adjustment and then equally to all sectors to the extent they stay within the above constraints.

2

If, at the time of a rebalance of the Index, the aggregate weight of the Index Companies in a particular sector is insufficient to achieve the target sector weight due to the individual security constraints described above, the Index will include an allocation to a sector-specific ETF to supplement the sector exposure, as needed.

Additionally, at the time of each rebalance, the Index weight for sectors having fewer than five Index Companies will include an allocation to a sector-specific ETF, as follows: sectors with four or five Index Companies will allocate 50% to sector-specific ETFs, sectors with one to three Index Companies will allocate 66.7% to sector-specific ETFs, and sectors with zero Index Companies will allocate 100% to sector-specific ETFs. The specific ETFs utilized by the Index are determined based on a combination of factors including their liquidity, fees and expenses, and ability to closely track an index representing the applicable sector of the U.S. equity market.

The Index is rebalanced and reconstituted on a quarterly basis after market close on the 10th trading day of each January, April, July, and October. The data used to compute each ACSI Company’s score is updated based on the Customer Satisfaction Data on a rolling basis, no less often than quarterly, with new data replacing earlier data collected in the same period of the previous year.

The Index was developed by the Adviser in 2016 in anticipation of the commencement of operations of the Fund.

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. 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 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 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.

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 or in the portfolios of ETFs in which the Fund invests (“Underlying ETFs”) 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. Common stocks, such as those held by the Fund or the Underlying ETFs, are generally exposed to greater risk than other types of securities, such as preferred stock and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

3

· Investment Company Risk. The risks of investing in investment companies, such as the Underlying ETFs, typically reflect the risks of the types of instruments in which the investment companies invest. By investing in another investment company, the Fund becomes a shareholder of that investment company and bears its proportionate share of the fees and expenses of the other investment company. Investments in ETFs are also subject to the following risks: (i) the market price of an ETF’s shares may trade above or below their NAV; (ii) an active trading market for an ETF’s shares may not develop or be maintained; and (iii) trading of an ETF’s shares may be halted for a number of reasons.

· Models and Data Risk.  The composition of the Index is heavily dependent on proprietary quantitative models 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, 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.

· Passive Investment Risk. The Fund invests in the securities included in, or representative of, its Index regardless of their investment merit. The Fund does not attempt to outperform its Index or take defensive positions in declining markets. As a result, the Fund’s performance may be adversely affected by a general decline in the market segments relating to its Index.

· 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.

o Consumer Discretionary Risk. The Fund may invest in companies in the consumer discretionary sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. The success of consumer product manufacturers and retailers is tied closely to the performance of domestic and international economies, interest rates, exchange rates, competition, consumer confidence, changes in demographics and consumer preferences. Companies in the consumer discretionary sector depend heavily on disposable household income and consumer spending, and may be strongly affected by social trends and marketing campaigns. These companies may be subject to severe competition, which may have an adverse impact on their profitability.

o Consumer Staples Sector Risk. The Fund may invest in companies in the consumer staples sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. Companies in the consumer staples sector, including those in the food and beverage industries, may be affected by general economic conditions, commodity production and pricing, consumer confidence and spending, consumer preferences, interest rates, product cycles, marketing campaigns, competition, and government regulations.

o Information Technology Sector Risk. The Fund may invest in companies in the information technology sector, and therefore the performance of the Fund could be negatively impacted by events affecting this sector. 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 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.

Performance

The Fund is new and therefore does not have a performance history for a full calendar year. In the future, performance information for the Fund will be presented in this section. Updated performance information is also available on the Fund’s website at www.acsietf.com or by calling the Fund toll free at 1‑800‑617‑0004.

Management

Investment Adviser

CSat Investment Advisory, L.P., doing business as ACSI Funds, serves as investment adviser to the Fund.

Portfolio Manager

Charles Ragauss, CFA, is Director of Product Management for the Adviser and has been the Fund’s portfolio manager since its inception in 2016.

Purchase and Sale of Shares

Shares are listed on a national securities exchange, such as BATS Exchange, Inc. (the “Exchange”), and most investors will buy and sell Shares through brokers at market prices, rather than NAV. Because the 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 50,000 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.
