Portfolio Turnover [Heading]

Portfolio Turnover

Portfolio Turnover [Text Block]

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. For the fiscal year ended April 30, 2018, the Fund’s portfolio turnover rate was 10% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

The Fund will normally invest at least 80% of its total assets in securities of the Index. The Index is designed to measure the performance of issuers in developed markets countries that are considered to be “Knowledge Leaders,” as defined and determined by Knowledge Leaders Capital, LLC, the Fund’s Index Provider (the “Index Provider”), based on a proprietary selection model developed by the Index Provider and incorporated into the Index methodology. 

The eligible universe of Index components includes companies that account for 85% of the market capitalization of developed market country companies that have a stock price greater than $1, excluding all secondary listings, preferred shares, and American Depository Receipts. Of those, companies in the lowest 10% in terms of trading liquidity (shares traded multiplied by share price) are eliminated. A proprietary selection model is then applied to create an intangible-adjusted financial history for each remaining company. The selection model does this by making adjustments to each company’s reported financial data since 1980 (or since the company’s inception, if later) that cause intangible investments to be treated as identical to tangible investments. For this purpose, intangible assets include research and development, advertising, brand development, and employee training expenses. The selection model then applies the Index Provider’s “Knowledge Leaders” screen, a proprietary, quantitative process used to measure a company’s intangible-adjusted financial history for knowledge and innovation intensity, financial strength, and profitability. Companies are graded on a “pass/fail” basis and those companies that pass each level of the screen are identified as Knowledge Leaders and included on the Index. From time to time, the Fund may have a significant portion of its assets invested in the securities of companies in one or more countries or regions and/or sectors. The Index may include companies of any market capitalization. Components in the Index are equal-weighted at the time of each Index rebalancing. The Index is rebalanced on a semi-annual basis. As of the date of this Prospectus, the Index comprised 784 component securities.

The Fund uses a passive investment strategy designed to track the performance of the Index. The Fund’s sub-adviser, Penserra Capital Management LLC (“Penserra” or the “Sub-Adviser”), uses a representative sampling strategy to manage the Fund. Representative sampling is an indexing strategy that involves investing in a representative sample of the Index’s component securities that collectively has an investment profile similar to the Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as industry weightings), fundamental characteristics (such as return variability) and liquidity measures similar to those of the Index. The Fund may or may not hold all of the securities in the Index. “Tracking error” is the difference between the performance (return) of the Fund’s portfolio and that of the Index. Funds that employ a representative sampling strategy may incur tracking error to a greater extent than funds that seek to replicate an index. The Fund expects that over time, if it has sufficient assets, the correlation between the Fund’s performance, before fees and expenses, and that of the Index will be 95% or better. A figure of 100% would indicate perfect correlation. 

The Fund may invest up to 20% of its assets in investments that are not included in the Index, but that the Fund’s investment adviser, Exchange Traded Concepts, LLC (the “Adviser”), or Sub-Adviser believes will help the Fund track the Index. Such investments include other investment companies, cash and cash equivalents, and money market instruments.

The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent that the Index concentrates in an industry or group of industries. As of the date of this Prospectus, the Index was not concentrated in any industry. In addition, in replicating the Index, the Fund may from time to time invest a significant portion of its assets in the securities of companies in one or more sectors. As of the date of this Prospectus, a significant portion of the Index consisted of companies in the information technology sector.

The Index Provider is not affiliated with the Fund, the Adviser, or the Sub-Adviser. The Index Provider developed the methodology for determining the securities to be included in the Index and for the ongoing maintenance of the Index. The Index is calculated and administered by Solactive AG, which is not affiliated with the Fund, the Adviser, the Sub-Adviser, or the Index Provider.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

As with all funds, a shareholder is subject to the risk that his or her investment could lose money. The principal risks affecting shareholders’ investments in the Fund are set forth below. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk: Because the Fund is an exchange-traded fund (“ETF”), only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem Shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Shares may trade at a material discount to NAV and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) 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.

Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and therefore takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Currency Exchange Rate Risk. The Fund may invest a relatively large percentage of its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Because the Fund’s net asset value (“NAV”) is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money. 

Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

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 expropriation, nationalization or adverse political or economic developments. Foreign securities may have relatively low market liquidity and decreased publicly available information about issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. Non-U.S. issuers may also be subject to inconsistent and potentially less stringent accounting, auditing, financial reporting and investor protection standards than U.S. issuers. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

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 April 30, 2018, a significant portion of the Fund’s assets was invested in securities of U.S. and Japanese issuers.

Investing in the United States Risk. Certain changes in the U.S. economy, such as when the U.S. economy weakens or when its financial markets decline, may have an adverse effect on the securities to which the Fund has exposure.

Investing in Japan Risk. The growth of Japan’s economy has historically lagged that of its Asian neighbors and other major developed economies. The Japanese economy is heavily dependent on international trade and has been adversely affected by trade tariffs, other protectionist measures, competition from emerging economies and the economic conditions of its trading partners.

Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.

Index Tracking Risk. The Fund’s return may not match or achieve a high degree of correlation with the return of the Index.

Industry Concentration Risk.  Because the Fund’s assets will be concentrated in an industry or group of industries to the extent the Index concentrates in a particular industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.  

Issuer-Specific Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.

Large-Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies.

Liquidity Risk. Liquidity risk exists when particular Fund investments are difficult to purchase or sell. This can reduce the Fund’s returns because the Fund may be unable to transact at advantageous times or prices.

Market Risk. The market price of a security or instrument could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Non-Diversification Risk. The Fund is non-diversified, meaning that, as compared to a diversified fund, it can invest a greater percentage of its assets in securities issued by or representing a small number of issuers.  As a result, the performance of these issuers can have a substantial impact on the Fund’s performance.

Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund.

Passive Investment Risk. The Fund is not actively managed and therefore the Fund 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 is otherwise required upon a rebalancing of the Index.

Portfolio Turnover Risk. The Fund’s investment strategy may result in relatively high portfolio turnover, which may result in increased transaction costs and may lower Fund performance

Sampling Risk. The Fund’s use of a representative sampling approach will result in its holding a smaller number of securities than are in the Index. As a result, an adverse development respecting an issuer of securities held by the Fund could result in a greater decline in NAV than would be the case if the Fund held all of the securities in the Index. Conversely, a positive development relating to an issuer of securities in the Index that is not held by the Fund could cause the Fund to underperform the Index. To the extent the assets in the Fund are smaller, these risks will be greater.

Sector Focus Risk.  The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors.  While the Fund’s sector exposure is expected to vary over time based on the composition of the Index, the Fund anticipates that it may be subject to some or all of the risks described below. The list below is not a comprehensive list of the sectors to which the Fund may have exposure over time and should not be relied on as such.

Consumer Discretionary Sector Risk. Consumer discretionary companies are companies that provide non-essential goods and services, such as retailers, media companies and consumer services. These companies manufacture products and provide discretionary services directly to the consumer, and the success of these companies is tied closely to the performance of the overall domestic and international economy, interest rates, competition and consumer confidence.

Consumer Staples Sector Risk.  Companies in the consumer staples sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drinks may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Health Care Sector Risk.  The health care sector may be affected by government regulations and government healthcare programs, increases or decreases in the cost of medical products and services and product liability claims, among other factors. Many health care companies are heavily dependent on patent protection, and the expiration of a patent may adversely affect their profitability. Health care companies are subject to competitive forces that may result in price discounting, and may be thinly capitalized and susceptible to product obsolescence. 

Industrials Sector Risk.  The industrials sector can be significantly affected by, among other things, worldwide economy growth, supply and demand for specific products and services and for industrial sector products in general, product obsolescence, rapid technological developments, international political and economic developments, claims for environmental damage or product liability, tax policies, and government regulation.

Information Technology Sector Risk. Information technology companies may also be smaller and less experienced companies, with limited product lines, markets or financial resources and fewer experienced management or marketing personnel. Information technology company stocks, especially those which are Internet related, have experienced extreme price and volume fluctuations that are often unrelated to their operating performance. 

Materials Sector Risk: Companies in the materials sector could be affected by, among other things, commodity prices, government regulation, inflation expectations, resource availability, and economic cycles.  

Small- and Mid-Capitalization Risk. The small- and mid-capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of small- and mid-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole.

Trading Risk. Shares may trade on NYSE Arca, Inc. (the “Exchange”) above or below their NAV. The NAV of Shares will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Shares are currently listed on the Exchange, there can be no assurance that an active trading market for Shares will develop or be maintained.  Trading in Fund Shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable.

Portfolio Turnover [Heading]

Portfolio Turnover

Portfolio Turnover [Text Block]

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. For the fiscal period July 10, 2017 (commencement of operations) through April 30, 2018, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy [Heading]

Principal Investment Strategies

Strategy Narrative [Text Block]

The Fund will normally invest at least 80% of its total assets in securities of the Index. The Index is designed to measure the performance of companies which are official sponsors of the major professional football, baseball, hockey and basketball leagues in the United States (“ProSports Sponsors”) or national sports broadcasters/internet streamers with rights agreements with such leagues (“ProSports Broadcasters”). 

Eligible Index constituents are common equity securities and American Depositary Receipts (“ADRs”) of ProSports Sponsors and ProSports Broadcasters or their parent companies that are traded on a U.S. or non-U.S. exchange. At the time of inclusion and rebalance, each issuer must have a market capitalization of at least $1 billion, an average daily trading volume of at least $1 million over the previous six months, and traded on 90% of the eligible trading days over the previous six months. The Index may consist of securities of both U.S. and foreign issuers, including securities of issuers located in emerging market countries. Index constituents that are ProSports Sponsors are rebalanced on the last trading day in April, September and November, consistent with the end of the month following the start of the season of each major professional sports league. Index constituents that are ProSports Broadcasters are rebalanced on the last trading day in January. All Index constituents may be rebalanced more frequently in response to specific corporate events, as determined by SportsETFs LLC (the “Index Provider”). The Index is unmanaged and cannot be invested in directly.

The Fund employs a “passive management” investment strategy designed to track the performance of the Index. Vident Investment Advisory, LLC (the “Sub-Adviser”), the Fund’s sub-adviser, generally will use a replication methodology, meaning it will invest in all of the securities composing the Index in proportion to their respective weightings in the Index. However, the Sub-Adviser may utilize a sampling methodology under various circumstances, including when it may not be possible or practicable to purchase all of the securities in the Index. Exchange Traded Concepts, LLC (the “Adviser”) expects that over time, if the Fund has sufficient assets, the correlation between the Fund’s performance, before fees and expenses, and that of the Index will be 95% or better. A figure of 100% would indicate perfect correlation.

The Fund may invest up to 20% of its total assets in investments that are not included in the Index, but that the Adviser or the Sub-Adviser believes will help the Fund track the performance of the Index. Such investments include cash, cash equivalents, and money market instruments.

The Fund will concentrate its investments (i.e., invest more than 25% of its total assets) in a particular industry or group of industries to approximately the same extent the Index concentrates in an industry or group of industries. As of the date of this Prospectus, the Index was not concentrated in any industry. In addition, in replicating the Index, the Fund may from time to time invest a significant portion of its assets in the securities of companies in one or more sectors. As of the date of this Prospectus, a significant portion of the Index consisted of companies in the consumer staples sector.

The Index Provider is not affiliated with the Fund, the Adviser, or the Sub-Adviser. The Index Provider developed the methodology for determining the securities to be included in the Index and is responsible for the ongoing maintenance of the Index. The Index is calculated and administered by Solactive AG, which is not affiliated with the Fund, the Adviser, the Sub-Adviser, or the Index Provider.

Risk [Heading]

Principal Risks

Risk Narrative [Text Block]

As with all funds, a shareholder is subject to the risk that his or her investment could lose money. The principal risks affecting shareholders’ investments in the Fund are set forth below. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the FDIC or any government agency.

ADR Risk. To the extent the Fund seeks exposure to foreign companies, the Fund’s investments may be in the form of depositary receipts or other securities convertible into securities of foreign issuers, including ADRs. While the use of ADRs, which are traded on exchanges and represent an ownership in a foreign security, provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to certain of the risks associated with investing directly in foreign securities.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Because the Fund is an exchange-traded fund (“ETF”), only a limited number of institutional investors (known as “Authorized Participants”) are authorized to purchase and redeem Shares directly from the Fund. In addition, there may be a limited number of market makers and/or liquidity providers in the marketplace. To the extent either of the following events occur, Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) Authorized Participants exit the business or otherwise become unable to process creation and/or redemption orders and no other Authorized Participants step forward to perform these services, or (ii) 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.

Common Stock Risk. Common stock holds the lowest priority in the capital structure of a company, and therefore takes the largest share of the company’s risk and its accompanying volatility. The value of the common stock held by the Fund may fall due to general market and economic conditions, perceptions regarding the industries in which the issuers of securities held by the Fund participate, or facts relating to specific companies in which the Fund invests.

Currency Exchange Rate Risk. The Fund may invest a relatively large percentage of its assets in securities denominated in non-U.S. currencies. Changes in currency exchange rates and the relative value of non-U.S. currencies will affect the value of the Fund’s investment and the value of your Shares. Because the Fund’s net asset value (“NAV”) is determined in U.S. dollars, the Fund’s NAV could decline if the currency of the non-U.S. market in which the Fund invests depreciates against the U.S. dollar, even if the value of the Fund’s holdings, measured in the foreign currency, increases. Currency exchange rates can be very volatile and can change quickly and unpredictably. As a result, the value of an investment in the Fund may change quickly and without warning and you may lose money.

Early Close/Trading Halt Risk. An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. 

Emerging Markets Securities Risk. Emerging markets are subject to greater market volatility, lower trading volume, political and economic instability, uncertainty regarding the existence of trading markets and more governmental limitations on foreign investment than more developed markets. In addition, securities in emerging markets may be subject to greater price fluctuations than securities in more developed markets. An investment in securities of foreign companies may be in the form of depositary receipts or other securities convertible into securities of foreign issuers.

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 expropriation, nationalization or adverse political or economic developments. Foreign securities may have relatively low market liquidity and decreased publicly available information about issuers. Investments in non-U.S. securities also may be subject to withholding or other taxes and may be subject to additional trading, settlement, custodial, and operational risks. Non-U.S. issuers may also be subject to inconsistent and potentially less stringent accounting, auditing, financial reporting and investor protection standards than U.S. issuers. These and other factors can make investments in the Fund more volatile and potentially less liquid than other types of investments.

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.

Geopolitical Risk. Some countries and regions in which the Fund invests have experienced security concerns, war or threats of war and aggression, terrorism, economic uncertainty, natural and environmental disasters and/or systemic market dislocations that have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on the U.S. and world economies and markets generally, each of which may negatively impact the Fund’s investments.

Index Tracking Risk. The Fund’s return may not match or achieve a high degree of correlation with the return of the Index.

Industry Concentration Risk. Because the Fund’s assets will be concentrated in an industry or group of industries to the extent the Index concentrates in a particular industry or group of industries, the Fund is subject to loss due to adverse occurrences that may affect that industry or group of industries.

Issuer-Specific Risk. Fund performance depends on the performance of individual securities to which the Fund has exposure. Issuer-specific events, including changes in the financial condition of an issuer, can have a negative impact on the value of the Fund.

Large Capitalization Risk. Returns on investments in securities of large companies could trail the returns on investments in securities of smaller and mid-sized companies.

Market Risk. The market price of a security or instrument could decline, sometimes rapidly or unpredictably, due to general market conditions that are not specifically related to a particular company, such as real or perceived adverse economic or political conditions throughout the world, changes in the general outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The market value of a security may also decline because of factors that affect a particular industry or industries, such as labor shortages or increased production costs and competitive conditions within an industry.

Operational Risk. The Fund and its service providers may experience disruptions that arise from human error, processing and communications errors, counterparty or third-party errors, technology or systems failures, any of which may have an adverse impact on the Fund.

Passive Investment Risk. The Fund is not actively managed and therefore the Fund 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 is otherwise required upon a rebalancing of the Index.

Portfolio Turnover Risk. In seeking to replicate the Index, which is adjusted and rebalanced quarterly, the Fund may incur relatively high portfolio turnover. High portfolio turnover may result in increased transaction costs and may lower Fund performance.

Sector Focus Risk. The Fund may invest a significant portion of its assets in one or more sectors and thus will be more susceptible to the risks affecting those sectors.  While the Fund’s sector exposure is expected to vary over time based on the composition of the Index, the Fund anticipates that it may be subject to some or all of the risks described below. The list below is not a comprehensive list of the sectors to which the Fund may have exposure over time and should not be relied on as such.

Consumer Staples Sector Risk. Companies in the consumer staples sector are subject to government regulation affecting the permissibility of using various food additives and production methods, which regulations could affect company profitability. Tobacco companies may be adversely affected by the adoption of proposed legislation and/or by litigation. Also, the success of food and soft drinks may be strongly affected by fads, marketing campaigns and other factors affecting supply and demand.

Small and Mid-Capitalization Risk. The small and mid-capitalization companies in which the Fund invests may be more vulnerable to adverse business or economic events than larger, more established companies, and may underperform other segments of the market or the equity market as a whole. Securities of small- and mid-capitalization companies generally trade in lower volumes, are often more vulnerable to market volatility, and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. 

Trading Risk. Shares of the Fund may trade on Cboe BZX Exchange, Inc. (the “Exchange”) above or below their NAV. The NAV of Shares will fluctuate with changes in the market value of the Fund’s holdings. In addition, although the Fund’s Shares are currently listed on the Exchange, there can be no assurance that an active trading market for Shares will develop or be maintained. Trading in Fund Shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Shares inadvisable.
