Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a “passive management” (or indexing) approach to seek to track the total return performance, before fees and expenses, of the Index.

Innovation α^® United States Index

The Index uses an objective, rules-based methodology to track the returns of a portfolio of 100 exchange-listed equity securities of predominantly large-cap U.S. companies based on innovation ability. Innovation ability, or “Innovation α^®”, of a company is determined by assessing the economic strength of its intellectual property (e.g., patents, trademarks, and copyrights) and other intangible assets (e.g., contracts, licenses, designs, and permits) (collectively, “IP”). Up to 10% of the Index may be comprised of American Depositary Receipts (“ADRs”), which are securities traded on a local stock exchange that represent interests in securities issued by a foreign publicly listed company. The Index was developed in 2015 by M-CAM International LLC, the Fund’s index provider and investment adviser (“M-CAM” or the “Adviser”).

The initial identification of companies to be included in the Index is based on the quality of the IP they own and their expected ability to capitalize on that IP, as determined pursuant to the rules-based methodology. M-CAM maintains a large repository of data on state-granted IP from over 160 countries, including the United States (the “M‑CAM Data”). This data is used to assess the qualitative attributes of each eligible company’s IP through analysis of the extent to which a company’s rights in such IP are legally enforceable, the history or likelihood of the company’s IP being used, licensed, referenced, or reverse-engineered by other firms, and the diversity of industries to which the IP is applied (the “Qualitative Analysis”).

In implementing the Index’s methodology, M-CAM also objectively measures the quantitative attributes of each eligible company’s IP by comparing them to the IP held by other firms and calculating the expected economic impact of the IP on each firm. Using a patented linguistic analysis process (similar in concept to tools for detecting plagiarism), the quality of each firm’s IP is measured against business transactions reported in financial statements, contracts, bid proposals, trade records, and other publicly available (but hard to find) data (the “Quantitative Analysis”). This analysis provides a measure of each individual company’s innovation ability and use of such ability. It also provides a relative score of how one company’s performance is expected to compare with the performance of others with whom it cooperates or competes. The measured difference between better and worse performers is defined by the Adviser as “Innovation α^®.”

Annually on the first trading day in January, the M-CAM Data is utilized to identify a set of peer companies with IP involving products, processes, methods, or utilities similar to that of each current Index constituent. The Index then performs the Qualitative Analysis and Quantitative Analysis on each Index constituent and each company in the peer group to determine whether to replace any current Index constituent with a member of its peer group. To reduce turnover, a maximum of ten Index constituents may be replaced during each annual reconstitution of the Index. Additionally, at the time of each reconstitution of the Index, at least 90 of the 100 companies in the Index must have a market capitalization in the range of the Russell 1000^® Index, which consists of the 1,000 largest U.S. companies, and no more than 10 of the 100 companies in the Index may be represented by ADRs and/or small- or mid-capitalization companies. Index constituents are rebalanced (but no companies are added to or deleted from the Index) on a quarterly basis on the first trading day of April, July, and October. At the time of each annual reconstitution in January and each quarterly rebalancing of the Index, companies included in the Index are weighted based on a modified equal-weight methodology that more heavily weights the companies that are expected to outperform the other peer companies. As of May 20, 2019, the three largest companies in the Index and their respective weightings were International Business Machines Corporation (7.38%), General Electric Company (6.81%), and Mastercard Inc. (2.44%).

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 investment 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 the Fund generally will invest in all of the component securities of the Index in approximately the same proportions 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 deemed to be “non-diversified,” which means that it may invest a greater percentage of its assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. The following risks could affect the value of your investment in the Fund:

•

Depositary Receipt Risk. Depositary receipts involve risks similar to those associated with investments in foreign securities, such as changes in political or economic conditions of other countries and changes in the exchange rates of foreign currencies. Depositary receipts listed on U.S. exchanges are issued by banks or trust companies, and entitle the holder to all dividends and capital gains that are paid out on the underlying foreign shares (“Underlying Shares”). When the Fund invests in depositary receipts as a substitute for an investment directly in the Underlying Shares, the Fund is exposed to the risk that the depositary receipts may not provide a return that corresponds precisely with that of the Underlying Shares.

•

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. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.


•	ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). 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) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs 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.


◦	Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦

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.

◦

Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.


•	Market Capitalization Risk


◦	Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦

Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s net asset value (“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.

•

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 a limited track record on which to base their investment decision.

•

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a small number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and have a greater impact on the Fund’s performance. However, the Fund intends to comply with the diversification requirements of the Internal Revenue Code of 1986, as amended (the “Code”), to qualify for treatment as a regulated investment company (“RIC”). For more information, please see the section entitled “Federal Income Taxes” in the SAI.


•	Passive Investment Risk. The Fund is not actively managed and its sub-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 as addressed in the Index methodology.


•	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.

•

Underlying Index Risk. Neither the Adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Underlying Index. The calculation and dissemination of the Underlying Index values may be delayed if the information technology or other facilities of the Underlying Index provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Underlying Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Underlying Index provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

To reduce turnover, a maximum of twelve Index constituents may be replaced during each annual reconstitution of the Index. Additionally, the 120 companies in the Index must be exchange-listed for a minimum of three years and must have a market capitalization in the range of the MSCI World Index, which consists of over 1,500 large-cap and mid-cap companies across 23 developed markets. Index constituents are rebalanced (but no companies are added to or deleted from the Index) on a quarterly basis on the first trading day of April, July, and October. At the time of each annual reconstitution in January and each quarterly rebalancing of the Index, companies included in the Index are weighted based on a modified equal-weight methodology that more heavily weights the companies that are expected to outperform other peer companies. In addition, there is a total weight constraint for each geographical market location based on the typical MSCI World Index distribution. As of May 20, 2019, the three largest companies in the Index and their respective weightings were Daimler AG (2.26%), Kering SA (2.21%), and Adidas AG (2.20%). As of January 31, 2019, the market capitalization range of the MSCI World Index was $1.2 billion to $803.9 billion.

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 and investments that have economic characteristics that are substantially identical to the economic characteristics of such component securities (e.g., depositary receipts). The Fund 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 the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index.

Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. The following risks could affect the value of your investment in the Fund:

•

Currency Exchange Rate Risk. The Fund invests in investments denominated in non-U.S. currencies or in securities that provide exposure to such 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. 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.

•

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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

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. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦

Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

•

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. 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. 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.


•	Market Capitalization Risk


◦	Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a “passive management” (or indexing) approach to seek to track the total return performance, before fees and expenses, of the Index.

Martin Global Innovation Equity (MGIE) Trade War Index

The Index uses an objective, rules-based methodology to track the returns of a portfolio of 120 global exchange-listed equity securities of predominantly large-cap and mid-cap companies based on the following:


1.	The Innovation ability, or “Innovation α^®”, of a company is determined by assessing the economic strength of a company’s intellectual property (e.g., patents, trademarks, and copyrights) and other intangible assets (e.g., contracts, licenses, designs, and permits) (collectively, “IP”); and


2.	The ability of a company to outperform its competitors during an international trade war as a result of its government patronage (e.g., government contracts with the company and subsidies) (“Government Patronage”).

The Index was developed in 2016 by M-CAM International LLC, the Fund’s index provider and investment adviser (“M-CAM” or the “Adviser”).

The initial identification of companies to be included in the Index is based on the quality of the IP they own and their expected ability to capitalize on that IP, as determined pursuant to the rules-based methodology. M-CAM maintains a large repository of data on state-granted IP from over 160 countries (the “M‑CAM Data”). The data is used to assess the qualitative attributes of each eligible company’s IP through analysis of the extent to which a company’s rights in such IP are legally enforceable, the history or likelihood of the company’s IP being used, licensed, referenced, or reverse-engineered by other firms, and the diversity of industries to which the IP is applied (the “Qualitative Analysis”).

In implementing the Index’s methodology, M-CAM also objectively measures the quantitative attributes of each eligible company’s IP by comparing them to the IP held by other firms and calculating the expected economic impact of the IP on each firm. Using a patented linguistic analysis process (similar in concept to tools for detecting plagiarism), the quality of each firm’s IP is measured against business transactions reported in financial statements, contracts, bid proposals, trade records, and other publicly available (but hard to find) data (the “Quantitative Analysis”). This analysis provides a measure of each individual company’s innovation ability and use of such ability. It also provides a relative score of how one company’s performance is expected to compare with the performance of others with whom it cooperates or competes. The measured difference between better and worse performers is defined by the Adviser as “Innovation α^®.”

Next, M-CAM will identify the extent to which each company is expected to be affected by a trade war. M-CAM has assembled data on state-sponsored enterprises, technology transfer, and joint ventures sourced from the U.S. Departments of the Treasury and Commerce, the Office of the United States Trade Representative, and their international equivalents (“M-CAM Trade War Data”). The M-CAM Trade War Data is analyzed to quantify each company’s Government Patronage. The Index uses a company’s Government Patronage as the key indication to select companies that will outperform their competitors in an international trade dispute.

Annually on the first trading day in January, the M-CAM Data is utilized to identify a set of peer companies with IP involving products, processes, methods, or utilities similar to that of each current Index constituent. The Index then performs the Qualitative Analysis, Quantitative Analysis, and Government Patronage analysis on each Index constituent and each company in the peer group to determine whether to replace any current Index constituent with a member of its peer group. To reduce turnover, a maximum of twelve Index constituents may be replaced during each annual reconstitution of the Index. Additionally, the 120 companies in the Index must be exchange-listed for a minimum of three years and must have a market capitalization in the range of the MSCI World Index, which consists of over 1,500 large-cap and mid-cap companies across 23 developed markets. Index constituents are rebalanced (but no companies are added to or deleted from the Index) on a quarterly basis on the first trading day of April, July, and October. At the time of each annual reconstitution in January and each quarterly rebalancing of the Index, companies included in the Index are weighted based on a modified equal-weight methodology that more heavily weights the companies that are expected to outperform the other peer companies. In addition, there is a total weight constraint for each geographical market location based on the typical MSCI World Index distribution. As of May 20, 2019, the three largest companies in the Index and their respective weightings were General Electric Company (2.18%), Cisco Systems Inc. (1.64%), and International Business Machines Corporation (1.36%). As of January 31, 2019, the market capitalization range of the MSCI World Index was $1.2 billion to $803.9 billion.

A company is considered to be involved in an international trade war when it is subject to trade restrictions, impositions of sanctions, or the filing of trade protests, disputes or complaints within the Dispute Settlement Bodies of the World Trade Organization. In addition, to qualify as a “trade war” these disputes must impact more than two disputing companies and must involve public statements or filings made by governments of two or more countries.

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 Fund 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 the Fund will generally invest in all of the component securities of the Index in the same approximate proportions 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 deemed to be “non-diversified,” which means that it may invest a greater percentage of its assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The principal risks of investing in the Fund are summarized below. The principal risks are presented in alphabetical order to facilitate finding particular risks and comparing them with other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. As with any investment, there is a risk that you could lose all or a portion of your investment in the Fund. The following risks could affect the value of your investment in the Fund:

•

Currency Exchange Rate Risk. The Fund invests primarily in investments denominated in non-U.S. currencies or in securities that provide exposure to such 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. 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.

•

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, sectors or companies in which the Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.


•	ETF Risks. The Fund is an ETF, and, as a result of an ETF’s structure, it is exposed to the following risks:

◦

Authorized Participants, Market Makers, and Liquidity Providers Concentration Risk. The Fund has a limited number of financial institutions that may act as Authorized Participants (“APs”). 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) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs 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.


◦	Costs of Buying or Selling Shares. Due to the costs of buying or selling Shares, including brokerage commissions imposed by brokers and bid/ask spreads, frequent trading of Shares may significantly reduce investment results and an investment in Shares may not be advisable for investors who anticipate regularly making small investments.

◦

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. Because securities held by the Fund may trade on foreign exchanges that are closed when the Fund’s primary listing exchange is open, the Fund is likely to experience premiums and discounts greater than those of domestic ETFs.

◦

Trading. Although Shares are listed for trading on the NYSE Arca, Inc. (the “Exchange”) and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that Shares will trade with any volume, or at all, on any stock exchange. In stressed market conditions, the liquidity of Shares may begin to mirror the liquidity of the Fund’s underlying portfolio holdings, which can be significantly less liquid than Shares.

•

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. 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. 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.


•	Market Capitalization Risk


◦	Large-Capitalization Investing. The securities of large-capitalization companies may be relatively mature compared to smaller companies and therefore subject to slower growth during times of economic expansion. Large-capitalization companies may also be unable to respond quickly to new competitive challenges, such as changes in technology and consumer tastes.

◦

Mid-Capitalization Investing. The securities of mid-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large-capitalization companies. The securities of mid-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large capitalization stocks or the stock market as a whole.

◦

Small-Capitalization Investing. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of large- or mid-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than large- or mid-capitalization stocks or the stock market as a whole. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies.


•	Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors. The Fund’s net asset value (“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.

•

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, non-diversified management investment company with no operating history. As a result, prospective investors have a limited track record on which to base their investment decision.

•

Non-Diversification Risk. Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a small number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and have a greater impact on the Fund’s performance. However, the Fund intends to comply with the diversification requirements of the Code to qualify for treatment as a RIC. For more information, please see the section entitled “Federal Income Taxes” in the SAI.


•	Passive Investment Risk. The Fund is not actively managed and its sub-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 rebalancing of the Index as addressed in the Index methodology.


•	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.

•

Underlying Index Risk. Neither the Adviser nor the Index Provider is able to guarantee the continuous availability or timeliness of the production of the Underlying Index. The calculation and dissemination of the Underlying Index values may be delayed if the information technology or other facilities of the Underlying Index provider, calculation agent, data providers and/or relevant stock exchange malfunction for any reason. A significant delay may cause trading in shares of the Fund to be suspended. Errors in Underlying Index data, computation and/or the construction in accordance with its methodology may occur from time to time and may not be identified and corrected by the Underlying Index provider, calculation agent or other applicable party for a period of time or at all, which may have an adverse impact on the Fund and its shareholders.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Because the Fund is “non-diversified,” it may invest a greater percentage of its assets in the securities of a single issuer or a small number of issuers than if it was a diversified fund. As a result, a decline in the value of an investment in a single issuer or a small number of issuers could cause the Fund’s overall value to decline to a greater degree than if the Fund held a more diversified portfolio. This may increase the Fund’s volatility and have a greater impact on the Fund’s performance. However, the Fund intends to comply with the diversification requirements of the Code to qualify for treatment as a RIC. For more information, please see the section entitled “Federal Income Taxes” in the SAI.
