The Next 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 Next Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Next Fund’s performance. No portfolio turnover rate is provided for the Next Fund because the Next Fund had not commenced operations prior to the date of this Prospectus.

This Example is intended to help you compare the cost of investing in the Next Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Next Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that: (1) your investment has a 5% return each year, and (2) the Next Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

rr_StrategyNarrativeTextBlock

The Next Fund is an exchange-traded fund (“ETF”) and employs a “passive management” – or indexing – investment approach designed to track the total return performance, before fees and expenses, of the Next Index. Motley Fool Asset Management, LLC (the “Adviser”) serves as the investment adviser to the Next Fund. The Next Index was developed by The Motley Fool, LLC (“TMF”), an affiliate of the Adviser.

The Next Index

The Next Index was established by TMF in 2021 and is a proprietary, rules-based index designed to track the performance of mid- and small-capitalization U.S. companies that have been recommended by TMF’s analysts and newsletters. TMF’s “recommendation universe” includes all companies domiciled in the United States that are either active recommendations of a newsletter published by TMF or are among the 150 highest rated U.S. companies in TMF’s analyst opinion database, subject to universe continuity rules.

To be eligible for inclusion in the Next Index, a security must first meet the existing eligibility criteria of the Motley Fool 100 Index, a proprietary, rules-based index designed to track the performance of the 100 largest, most liquid U.S. companies that have been recommended by TMF’s analysts and newsletters. However, the Next Index excludes the 100 largest securities that meet the Motley Fool 100 Index eligibility criteria, subject to universe continuity rules, and consists of the next largest companies with a 3-month average daily value traded greater than or equal to $1 million. The selection universe consists of companies of all market capitalizations. For this purpose, the Adviser defines small- and mid-capitalization companies as companies having capitalizations similar to, or less than, the companies in the Russell Midcap Index. To create the Motley Fool 100 Index, the largest 100 companies (based on market capitalization, but not restricted to any capitalization constraints) are selected. Given that the selection universe is dynamic, there is no guarantee that the smallest companies that make up the top 100 will always fit the definition of large capitalization, or that the first company (or companies) outside the top 100 will not fit the definition of large capitalization. Historically, the market capitalization weighting methodology has resulted in the Motley Fool 100 Index, under commonly accepted definitions, having attributes of a large capitalization index, and the Next Index having attributes of a small- and mid-capitalization index.

With respect to universe continuity, the Next Index is constructed utilizing a buffering methodology. The buffer is intended to reduce index turnover from movements in constituent weightings that could result in a company dropping out of the index only to be added back with the next rebalance. Specifically, stocks ranked in the top 105 positions based on TMF’s analyst opinion database (70% of the 150-stock target) are automatically included in the candidate universe. Additionally, companies that were previously eligible based on their TMF analyst ratings will still be included as long as their rank is equal to or better than 195 (130% of the 150-stock target). Stocks are then added based on conviction score rank until the 150-stock target is reached.

Once the eligible universe is determined, inclusion in the Motley Fool 100 Index and the Next Index are determined jointly based on market capitalization and index continuity rules. A buffer of 30% of the Motley Fool 100 Index membership target - or 30 stocks - is used to prevent frequent turnover around the Motley Fool 100 Index/Next Index cutoff.

Specifically, stocks ranked in the top 70 positions based on firm-level market capitalization (70% of the 100-stock target) are automatically included in the candidate universe for the Motley Fool 100 Index. Additionally, companies that were previously included in the Motley Fool 100 Index will still be included as long as their market capitalization rank is equal to or better than 130 (130% of the 100-stock target). Stocks are then added to the Motley Fool 100 Index based on conviction score rank until the 100-stock target is reached. The remaining stocks are included in the Next Index.

Each selected company’s share of the Next Index (or “weighting”) is set to equal the company’s share of all Next Index companies’ aggregate market value. The Next Index is reconstituted and rebalanced quarterly. The Next Index will typically include 150 – 450 companies at any one time.

The Next Index is calculated and administered by Solactive AG (the “Index Calculation Agent”), which is not affiliated with the Next Fund, the Adviser or TMF. Additional information regarding the Next Index, including its value, is available on the websites of the Next Index at www.foolindices.com and the Index Calculation Agent, at www.solactive.com.

The Next Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Next Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Next Index. The Adviser expects that, over time, if it has sufficient assets, the correlation between the Next Fund’s performance and that of the Next Index, before fees and expenses, will be 95% or better.

The Next 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 Next Index. However, the Next Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Next Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Next Index as a whole, when the Adviser believes it is in the best interests of the Next Fund (e.g., when replicating the Next Index involves practical difficulties or substantial costs, a Next Index constituent becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations that apply to the Next Fund but not to the Next Index).

The Next 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 Next Index, but which the Adviser believes will help the Next Fund track the Next Index. For example, the Next Fund may invest in securities that are not components of the Next Index to reflect various corporate actions and other changes to the Next Index (such as reconstitutions, additions and deletions).

The Next Fund is non-diversified for the purposes of the Investment Company Act of 1940, as amended (“1940 Act”), which means that the Next Fund may invest in fewer securities at any one time than a diversified fund. To the extent the Next Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry, the Next Fund will concentrate its investments to approximately the same extent as the Next Index.

The Next Fund may also seek to increase its income by lending securities.

The Next Fund has elected to be, and intends to qualify each year for treatment as a regulated investment company (“RIC”) under Subchapter M of Subtitle A, Chapter 1, of the Internal Revenue Code of 1986, as amended (the “Code”).

Risk Nondiversified Status [Text]

rr_RiskNarrativeTextBlock

The value of the Next Fund’s investments may decrease, which will cause the value of the Next Fund’s Shares to decrease. As a result, you may lose money on your investment in the Next Fund, and there can be no assurance that the Next Fund will achieve its investment objective. The Next Fund’s 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 Next Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Next Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Next Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Next Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The Next Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Next Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Next Fund or its service providers may adversely impact and cause financial losses to the Next Fund or its shareholders. Issuers of securities in which the Next Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

●	ETF Risk. The Next 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,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”

●

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Next Fund has a limited number of financial institutions that are institutional investors and 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, Next Fund Shares may trade at a material discount to net asset value (“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. These events, among others, may lead to the Next Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Next Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, 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). This risk is heightened in times of market volatility or periods of steep market declines.

●

Shares May Trade at Prices Other Than NAV Risk. 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 Next 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). This risk is heightened in times of market volatility or periods of steep market declines.

●

Equity Markets Risk. The equity securities held in the Next 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 Next 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.

●

Index Rankings and Methodology Risk. Factors used by TMF’s analysts in their qualitative and quantitative analysis of companies included in the Next Index, and the weight placed on those factors, may not be predictive of a security’s value and, thus, have an adverse effect on the Next Fund. In addition, changes in TMF’s recommendations or rankings methodologies may have an adverse effect on the Next Fund. Factors that affect a security’s value can change over time, and these changes may not be reflected in the Next Index methodology. Moreover, the methodology and the calculation of the Next Index could be subject to errors. If the composition of the Next Index reflects such errors, the Next Fund’s portfolio can be expected to reflect the errors, too.

●

Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Next Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

●

Mid-Capitalization Companies Risk. Investments in securities of mid-capitalization companies may involve greater risks than do investments in larger, more established companies. The prices of securities of mid-cap companies tend to be more vulnerable to adverse developments specific to a company or its industry, or the securities markets generally, than are securities of larger capitalization companies.

●

New Fund Risk. The Next Fund is a recently organized, non-diversified management investment company with no operating history. In addition, there can be no assurance that the Next Fund will grow to, or maintain, an economically viable size, in which case the Board of Directors (the “Board”) of The RBB Fund, Inc. (the “Company”) may determine to liquidate the Next Fund.

●

Non-Diversification Risk. The Next Fund is non-diversified, which means that it may invest a high percentage of its assets in a limited number of securities. Since the Next Fund is non-diversified, its NAV, market price and total returns may fluctuate or fall more than a diversified fund. Gains or losses on a single stock may have a greater impact on the Next Fund.

●

Passive Investment Risk. The Next Fund is not actively managed and the Adviser does not attempt to take defensive positions in any market conditions, including adverse markets. The Next Fund and its Adviser will 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 Next Index or the selling of shares of that security is otherwise required upon a reconstitution of the Next Index as addressed in the Index methodology.

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

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

● Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and global economy, interest rates, competition, and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their respective profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

● Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by regulatory changes. Other risk factors include rising costs of medical products and services, pricing pressure and limited product lines, loss or impairment of intellectual property rights and litigation regarding product or service liability.

● Industrials Sector Risk. Companies in the industrials sector could be affected by, among other things, government regulation, world events and economic conditions, insurance costs, and labor relations issues.

● Information Technology Sector Risk. In addition to market or economic factors, companies in the information technology sector and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition.

●	*Securities Lending Risk.* The Next Fund may lend portfolio securities to institutions, such as certain broker- dealers. The Next Fund may experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

●

Small-Capitalization Companies Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

●

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

The Capital Efficiency Fund is an exchange-traded fund (“ETF”) and employs a “passive management” – or indexing – investment approach designed to track the total return performance, before fees and expenses, of the Capital Efficiency 100 Index. Motley Fool Asset Management, LLC (the “Adviser”) serves as the investment adviser to the Capital Efficiency Fund. The Capital Efficiency 100 Index was developed by The Motley Fool, LLC (“TMF”), an affiliate of the Adviser.

The Motley Fool Capital Efficiency 100 Index

The Capital Efficiency 100 Index was established by TMF in 2021 and is a proprietary, rules-based index designed to track the performance of the highest scoring stocks of U.S. companies, measured by a company’s capital efficiency, that have been recommended by TMF’s analysts and newsletters, and that also meet certain liquidity requirements. Capital efficiency is a measure of how a business turns its investments into revenue and profit and it provides insight into the company’s return on invested capital.

TMF’s “recommendation universe” includes all companies domiciled in the United States that are either active recommendations of a newsletter published by TMF or are among the 150 highest rated U.S. companies in TMF’s analyst opinion database, subject to universe continuity rules. With respect to universe continuity, the Capital Efficiency 100 Index is constructed utilizing a buffering methodology. The buffer is intended to reduce index turnover from movements in constituent weightings that could result in a company dropping out of the index only to be added back with the next rebalance. Specifically, stocks ranked in the top 105 positions based on TMF’s analyst opinion database (70% of the 150-stock target) are automatically included in the candidate universe. Additionally, companies that were previously eligible based on their TMF analyst ratings will still be included as long as their rank is equal to or better than 195 (130% of the 150-stock target). Stocks are then added based on conviction score rank until the 150-stock target is reached.

Company shares that meet the requirements for universe inclusion must also meet the minimum requirements for liquidity and for calculating the Capital Efficiency Score. Specifically, the liquidity requirements mandate that at least $1 million worth of a company’s shares trade daily, on average, during the preceding three months. With respect to calculating capital efficiency, a company must report gross profits (or net revenues for financial companies) and meet a minimum total assets threshold as of the most recent filing prior to each index weighting date. TMF’s proprietary Capital Efficiency Factor Score is a composite score that incorporates growth, profitability, and stability metrics in assessing a company’s capital efficiency. To determine final index membership, candidate stocks are first ranked based on their composite scores. The top 100 stocks are then selected based on index continuity rules.

Each selected company’s share of the Capital Efficiency 100 Index (or “weighting”) is set to equal the company’s share of all Capital Efficiency 100 Index companies’ aggregate market value multiplied by their respective Capital Efficiency Scores. A maximum position size limit of 5% is also enforced (tested at the time of rebalancing and subject to index continuity rules). The Capital Efficiency 100 Index is reconstituted and rebalanced quarterly.

The Capital Efficiency 100 Index will typically include 100 companies at any one time and may contain companies of any size capitalization.

The Capital Efficiency 100 Index is calculated and administered by Solactive AG (the “Index Calculation Agent”), which is not affiliated with the Capital Efficiency Fund, the Adviser or TMF. Additional information regarding the Capital Efficiency 100 Index, including its value, is available on the websites of the Capital Efficiency 100 Index at www.foolindices.com and the Index Calculation Agent, at www.solactive.com.

The value of the Capital Efficiency Fund’s investments may decrease, which will cause the value of the Capital Efficiency Fund’s Shares to decrease. As a result, you may lose money on your investment in the Capital Efficiency Fund, and there can be no assurance that the Capital Efficiency Fund will achieve its investment objective.

Each risk summarized below is considered a “principal risk” of investing in the Capital Efficiency Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Capital Efficiency Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Capital Efficiency Fund, the Adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent the Capital Efficiency Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The Capital Efficiency Fund and the Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Capital Efficiency Fund or the Adviser.

ETF Risk. The Capital Efficiency 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,” “Secondary Market Trading Risk,” and “Shares May Trade at Prices Other Than NAV Risk.”

●

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. The Capital Efficiency Fund has a limited number of financial institutions that are institutional investors and 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, Capital Efficiency Fund Shares may trade at a material discount to net asset value (“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. These events, among others, may lead to the Capital Efficiency Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Capital Efficiency Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the NYSE Arca, Inc. (the “Exchange”), and may be traded on U.S. exchanges other than the Exchange, there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. During periods of market stress, 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). This risk is heightened in times of market volatility or periods of steep market declines.

Shares May Trade at Prices Other Than NAV Risk. 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 Capital Efficiency 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). This risk is heightened in times of market volatility or periods of steep market declines.

●

Equity Markets Risk. The equity securities held in the Capital Efficiency 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 Capital Efficiency 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.

●

Index Rankings and Methodology Risk. Factors used by TMF’s analysts in their qualitative and quantitative analysis of companies included in the Capital Efficiency 100 Index, and the weight placed on those factors, may not be predictive of a security’s value and, thus, have an adverse effect on the Capital Efficiency Fund. In addition, changes in TMF’s recommendations or rankings methodologies may have an adverse effect on the Capital Efficiency Fund. Factors that affect a security’s value can change over time, and these changes may not be reflected in the Capital Efficiency 100 Index methodology. Moreover, the methodology and the calculation of the Capital Efficiency 100 Index could be subject to errors. If the composition of the Capital Efficiency 100 Index reflects such errors, the Capital Efficiency Fund’s portfolio can be expected to reflect the errors, too.

●	Large-Capitalization Investing Risk. 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.

●

Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Capital Efficiency Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

●

Mid-Capitalization Companies Risk. The securities of mid-capitalization companies may involve greater risks than do investments in larger, more established companies. The prices of securities of mid-cap companies tend to be more vulnerable to adverse developments specific to a company or its industry, or the securities markets generally, than are securities of larger capitalization companies.

●

New Fund Risk. The Capital Efficiency Fund is a recently organized, non-diversified management investment company with no operating history. In addition, there can be no assurance that the Capital Efficiency Fund will grow to, or maintain, an economically viable size, in which case the Board of Directors (the “Board”) of The RBB Fund, Inc. (the “Company”) may determine to liquidate the Capital Efficiency Fund.

●

Non-Diversification Risk. The Capital Efficiency Fund is non-diversified, which means that it may invest a high percentage of its assets in a limited number of securities. Since the Capital Efficiency Fund is non-diversified, its NAV, market price and total returns may fluctuate or fall more than a diversified fund. Gains or losses on a single stock may have a greater impact on the Capital Efficiency Fund.

●

Passive Investment Risk. The Capital Efficiency Fund is not actively managed and the Adviser does not attempt to take defensive positions in any market conditions, including adverse markets. The Capital Efficiency Fund and its Adviser will 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 Capital Efficiency 100 Index or the selling of shares of that security is otherwise required upon a reconstitution of the Capital Efficiency 100 Index as addressed in the Index methodology.

●

Portfolio Turnover Risk. In seeking to replicate the Capital Efficiency 100 Index, which is adjusted and rebalanced quarterly, the Capital Efficiency Fund may incur relatively high portfolio turnover. High portfolio turnover may result in increased transaction costs and may lower Fund performance.

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

● Communication Services Sector Risk. Companies in the communications sector may be affected by industry competition, substantial capital requirements, government regulation, cyclicality of revenues and earnings, obsolescence of communications products and services due to technological advancement, a potential decrease in the discretionary income of targeted individuals and changing consumer tastes and interests.

● Consumer Discretionary Sector Risk. The success of consumer product manufacturers and retailers is tied closely to the performance of the overall domestic and global economy, interest rates, competition, and consumer confidence. Success depends heavily on disposable household income and consumer spending. Also, companies in the consumer discretionary sector may be subject to severe competition, which may have an adverse impact on their respective profitability. Changes in demographics and consumer tastes can also affect the demand for, and success of, consumer products and services in the marketplace.

● Health Care Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by regulatory changes. Other risk factors include rising costs of medical products and services, pricing pressure and limited product lines, loss or impairment of intellectual property rights and litigation regarding product or service liability.

● Information Technology Sector Risk. In addition to market or economic factors, companies in the information technology sector and companies that rely heavily on technology are particularly vulnerable to rapid changes in technology product cycles, rapid product obsolescence, government regulation and competition.

●	Securities Lending Risk. The Capital Efficiency Fund may lend portfolio securities to institutions, such as certain broker- dealers. The Capital Efficiency Fund may experience a loss or delay in the recovery of its securities if the borrowing institution breaches its agreement with the Fund.

●

Small-Capitalization Companies Risk. The securities of small-capitalization companies may be more vulnerable to adverse issuer, market, political, or economic developments than securities of larger-capitalization companies. The securities of small-capitalization companies generally trade in lower volumes and are subject to greater and more unpredictable price changes than larger capitalization stocks or the stock market as a whole. Some small capitalization companies have limited product lines, markets, and financial and managerial resources and tend to concentrate on fewer geographical markets relative to larger capitalization companies. There is typically less publicly available information concerning smaller-capitalization companies than for larger, more established companies. Small-capitalization companies also may be particularly sensitive to changes in interest rates, government regulation, borrowing costs and earnings.

●

Tracking Error Risk. As with all index funds, the performance of the Capital Efficiency Fund and its Index may differ from each other for a variety of reasons. For example, the Capital Efficiency Fund incurs operating expenses and portfolio transaction costs not incurred by the Capital Efficiency 100 Index. In addition, the Capital Efficiency Fund may not be fully invested in the securities of the Capital Efficiency 100 Index at all times or may hold securities not included in the Capital Efficiency 100 Index.

“Other Expenses” are estimated for the current fiscal year.

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Founders Class Shares and Investor Class Shares of 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 (taking into account any applicable contractual expense limitation until its expiration). Although your actual costs may be higher or lower, based on these assumptions your costs of investing in the Fund would be:

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets (including any borrowings for investment purposes) in a non-diversified portfolio of credit instruments and derivative instruments that are linked to, or provide investment exposure to, credit instruments. The Fund defines credit instruments broadly to include any debt instrument, including corporate debt securities, government and agency debt securities, leveraged loans (or bank loans), municipal securities, securitized instruments (including mortgage- and asset-backed securities) and shares of registered, closed-end or open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “Underlying Funds”) that have either adopted policies to invest at least 80% of their assets in credit instruments or invest substantially all of their assets in credit instruments. The Fund may invest in domestic and foreign credit instruments of any maturity and credit rating, and may invest a majority of its assets in credit instruments that are rated below investment grade (“high yield bonds”), which are also known as “junk bonds”, and/or credit instruments that are linked to, or provide investment exposure to high yield bonds.

To pursue its investment objective, the Fund uses a trend-following strategy that seeks to identify favorable market environments in high yield bonds. The Fund’s assets are managed in accordance with Anthony Capital Management, LLC’s (the “Sub-Adviser”) proprietary Tactical Risk Model (“TRM”). The TRM is a quantitatively-driven investment process that seeks to invest Fund assets (i) in high yield bonds and derivative instruments that are linked to, or provide investment exposure to, similar credit instruments when the Sub-Adviser believes that high yield bond markets are trending upwards (referred to herein as “Risk-On” environments); and (ii) in short-term fixed income securities or cash equivalents when the Sub-Adviser believes that high yield bond markets are trending downwards (referred to herein as “Risk-Off” environments). By tactically allocating its investments based upon market trends and momentum, the Fund seeks to reduce its exposure to declines in the high yield bond markets, thereby seeking to limit downside volatility and downside loss in down-trending markets. To determine whether a “Risk-On” or “Risk-Off” market environment exists, the Sub-Adviser systematically evaluates, among other things, price data from credit and equity markets, credit spreads, interest rates and other market-based indicators to provide a broad assessment of then-current market conditions.

Subject to the Sub-Adviser’s determination of the state of the then-current market environment, the Fund’s assets will generally be invested as follows:

“Risk-On” Environments. In “Risk-On” environments (i.e., where the Sub-Adviser believes that high-yield bond markets are trending upwards), the Fund will invest up to 25% of its assets in derivative instruments including credit default swaps (“CDS”), CDS indexes or baskets of underlying diversified high yield bond funds, high yield bond indices, high yield bond ETFs, bank loan funds, multi-sector bond funds and other fixed income funds and other ETFs.

“Risk-Off” Environments. In “Risk-Off” environments (i.e., where the Sub-Adviser believes that high-yield bond markets are trending downwards), the Fund’s assets will be invested primarily in cash equivalents or short-term fixed income securities, including bills, notes and bonds issued by the U.S. Treasury.

High Yield Exposure Through Credit Default Swaps

While the Fund may execute its investment strategy by investing in individual high yield securities, it is anticipated that the Fund will invest during “Risk-On” environments primarily by entering into CDS. CDS are typically two-party (bilateral) financial contracts that transfer credit exposure between the two parties. One party to a CDS (referred to as the credit protection “buyer”) receives credit protection or sheds credit risk, whereas the other party to a CDS (referred to as the credit protection “seller”) sells credit protection or takes on credit risk. The seller typically receives pre-determined periodic payments from the other party. These payments are in consideration for agreeing to make specific payments to the buyer should a negative credit event occur, such as (1) bankruptcy, or (2) failure to pay interest or principal on a reference debt instrument, with respect to a specified issuer or one of the reference issuers in a CDS portfolio. In general, CDS may be used by the Fund to obtain credit risk exposure similar to that of a direct investment in high yield bonds.

The Fund will use CDS as part of a replication tactic whereby the Fund combines a (1) CDS on a portfolio of high yield bonds with (2) investments in high quality securities, such as U.S. Treasury bills, as an economic substitute for a portfolio of individual high yield bonds. This two-instrument “replication portfolio” is expected to have an economic and investment return profile that is substantially similar, although not identical to, a cash portfolio of high yield bonds. If the Fund invests in a portfolio of individual high yield bonds, it earns interest and suffers losses when issuers default. Similarly, the replication portfolio receives nearly identical payments and suffers nearly identical losses to that of a portfolio of high yield bonds. The Fund receives interest (from the portfolio of high-quality securities) and receives payments from the credit protection buyer, which, in total, are approximately equal to the interest payments on a cash portfolio of high yield bonds. Additionally, the Fund makes credit default payments to the credit protection buyer counterparty that are nearly identical to credit losses the Fund would suffer from the default of issuers in a cash portfolio of high yield bonds.

The Fund anticipates that it will use a market-standard high yield reference portfolio known as the Markit CDX High Yield Index (the “CDX High Yield Index”) to execute its investment strategy. The CDX High Yield Index (composed of 5-year credit default swaps on 100 relatively liquid high yield fixed income securities issued by BB and B rated North American corporate entities) is selected and maintained by Markit Group Limited (“Markit Group”) using specific-issue recommendations and current market-based default swap rates provided by major high yield market participants, such as commercial banks and broker-dealers. Markit Group also provides daily updates of the then-current average credit default swap rate associated with each of the securities included in the CDX High Yield Index. The CDX High Yield Index and its average credit default swap rate are used by the Fund and its counterparties to set the terms of CDX High Yield Index-referenced CDS. Markit Group also provides credit default loss information and required credit event payments by conducting a survey or quasi-auction on securities included in the CDX High Yield Index that have suffered a credit event. This loss information is used to calculate payments due from a credit protection seller to the protection buyer. A new CDX High Yield Index is created every six months to update the Index for the purpose of replacing defaulted issuers and including new issuers, which are representative of the then-current high yield market. The Fund expects that it may maintain original CDS or enter into new transactions that terminate the old CDS and replace them with CDS using the newly-updated CDX High Yield Index.

The tactic of using a CDS referenced to the CDX High Yield Index differs from the tactic of investing in specific Sub-Adviser-selected high yield bonds because (1) it does not rely upon the issuer-specific credit research of the Sub-Adviser, (2) exposes the Fund to the credit risk of the counterparty in addition to the credit risk of the reference high yield portfolio, and (3) permits only long or short positions in the Index rather than more selective issuer-specific or sector-specific investments.

In addition to the CDX High Yield Index, the Fund may also use foreign credit default swap indexes to gain exposure to foreign (including emerging markets) fixed income securities.

Other Investments

The Fund may invest in a broad range of securities and engage in a broad range of investment techniques including the following:

· Credit Instruments: The Fund may invest in foreign and domestic credit instruments, including, without limitation, corporate and sovereign debt securities, government and agency debt securities, leveraged loans (or bank loans), municipal securities, securitized instruments (including mortgage- and asset-backed securities) and shares of Underlying Funds that have either adopted policies to invest at least 80% of their assets in credit instruments or invest substantially all of their assets in credit (collectively, “Credit Instruments”).

·

High Yield Debt Securities: The Fund may invest in high yield debt securities without restriction as to issuer, counterparty, country or capitalization, and without restriction as to credit quality, maturity, issuer type or structure. The Fund may invest in investment grade corporate bonds, as well as higher-yielding, higher-risk non-investment grade corporate bonds (which are also commonly called “high yield bonds” or “junk bonds”) with medium to low credit quality ratings. High yield bonds are generally credit instruments that are rated BB+ or lower by S&P Global Ratings (“S&P”) or Fitch Ratings, Inc. (“Fitch”), or Ba1 or lower by Moody’s Investors Service, Inc. (“Moody’s”), or, if unrated, determined by the Sub-Adviser, to be of comparable quality. High yield bonds have a higher expected rate of default than investment grade bonds. The Fund may invest in high yield bonds directly or through derivative instruments designed to replicate some or all of the features of an underlying portfolio of high yield bonds, such as CDS and credit default swap index products. See “High Yield Exposure Through Credit Default Swaps” section in the Fund’s principal investment strategy for more information regarding the Fund’s investments in high yield bond CDS.

·

Underlying Funds: The Fund may invest its assets in shares of Underlying Funds, to the extent permissible under 1940 Act. As a shareholder of one or more Underlying Funds, the Fund would bear, along with other shareholders, its pro rata portion of the other investment company’s expenses, including advisory fees. These expenses would be in addition to the advisory fee and other expenses that the Fund bears directly in connection with its own operations. The Fund expects that a significant portion of the Fund’s assets may be invested in Underlying Funds.

·

Derivatives: The Fund may invest in derivative products to be used by the Fund to obtain exposure to specific asset class sectors, such as the high yield bond sector, in order to invest long in the specific asset classes. These products include CDS and credit default swap index products (including CDX High Yield Index products). The Fund may also use other derivatives including, without limitation, options transactions, other swap transactions, futures and repurchase agreements, without regard to credit quality, maturity, issuer type or structure.

·

U.S. Government Securities: The Fund may invest in obligations issued by agencies and instrumentalities of the U.S. Government. These obligations vary in the level of support they receive from the U.S. Government. They may be: (i) supported by the full faith and credit of the U.S. Treasury, such as those of the Government National Mortgage Association; (ii) supported by the right of the issuer to borrow from the U.S. Treasury, such as those of the Federal National Mortgage Association; or (iii) supported only by the credit of the issuer, such as those of the Federal Farm Credit Bureau.

Defensive Periods

During defensive periods, as determined by the Sub-Adviser, the Fund may invest up to 100% of the Fund’s assets in high-quality, short-term debt securities and cash equivalents, including money market instruments and money market mutual funds. The Fund may also engage in derivative transactions to hedge against adverse price movements in credit instruments during defensive periods.

Risk Nondiversified Status [Text]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

The principal risk factors affecting shareholders' investments in the Fund are set forth below.

Active Management Risk. The Fund is subject to management risk as an actively-managed investment portfolio. The Fund’s ability to achieve its investment objective depends on the investment skill and ability of the Sub-Adviser and on the Sub-Adviser’s ability to correctly identify economic trends.

Cash Positions Risk. The Fund may hold a significant position in cash and/or cash equivalent securities. When the Fund’s investment in cash or cash equivalent securities increases, the Fund may not participate in market advances or declines to the same extent that it would if the Fund were more fully invested in other securities.

Counterparty Risk. Counterparty risk is the risk that the other party(s) to an agreement or a participant to a transaction might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.

Credit Default Swap Index Product Risk: A credit default swap index product is subject to the risks of the underlying credit default swap obligations, which include risks such as concentration risk and counterparty risk. Concentration risk refers to the certain large institutional buyers that may take large positions in credit default swaps. The failure of such a buyer could materially and adversely affect the credit default swap market as a whole. Counterparty risk refers to the risk that the counterparty to the swap will default on its obligation to pay.

Credit Default Swap Risk. Credit default swaps are typically two-party financial contracts that transfer credit exposure between the two parties. Under a typical CDS, one party (the “seller”) receives pre-determined periodic payments from the other party (the “buyer”). The seller agrees to make specific payments to the buyer if a negative credit event occurs, such as the bankruptcy of or default by the issuer of the underlying debt instrument. The use of CDS involves investment techniques and risks different from those associated with ordinary portfolio security transactions, such as potentially heightened counterparty or concentration risks.

Credit Risk. Credit risk is the risk that an issuer or other obligated party of a debt security may be unable or unwilling to make interest and principal payments when due. Changes in an issuer’s credit rating or the market’s perception of an issuer’s creditworthiness may also affect the value of the Fund’s investment in that issuer. Securities rated in the four highest categories by the rating agencies are considered investment grade but they may also have some speculative characteristics. Investment grade ratings do not guarantee that bonds will not lose value or default. In addition, the credit quality of securities may be lowered if an issuer’s financial condition changes. The Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, Optima Asset Management LLC (the “Adviser”), Sub-Adviser, custodian, transfer agent, distributor and/or other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its Adviser and Sub-Adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

Derivatives Risk. The Fund’s investments in derivative instruments including options, swaps and futures, which may be leveraged, may result in losses. Investments in derivative instruments may result in losses exceeding the amounts invested. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.

Emerging Markets Risk. Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. In addition, the information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

Fixed Income Securities Risk. Fixed income securities in which the Fund or an Underlying Fund may invest are subject to certain risks, including: interest rate risk, prepayment risk and credit/default risk. Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes. Prepayment risk involves the risk that in declining interest rate environments prepayments of principal could increase and require the Fund or an Underlying Fund to reinvest proceeds of the prepayments at lower interest rates. Credit risk involves the risk that the credit rating of a security may be lowered.

Foreign Securities Risk. The Fund’s or an Underlying Fund’s investments in foreign securities are subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, and differences in taxation, auditing and other financial practices. Investments in emerging market securities by the Fund or an Underlying Fund are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies. Certain foreign securities in which the Fund or an Underlying Fund may invest may be traded in markets that close before the time that the Fund or Underlying Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Fund or an Underlying Fund may invest may be listed on foreign exchanges that trade on weekends or other days when the Fund or Underlying Fund does not calculate its NAV. As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

Futures Risk. The value of a futures contract tends to increase and decrease in correlation with the value of the underlying instrument. Risks of futures contracts may arise from an imperfect correlation between movements in the price of the futures and the price of the underlying instrument. The Fund’s use of futures contracts exposes the Fund to leverage risk because of the small margin requirements relative to the value of the futures contract. While futures contracts are generally liquid instruments, under certain market conditions they may become illiquid. The price of futures can be highly volatile; using them could lower total return, and the potential loss from futures could exceed the Fund’s initial investment in such contracts.

Government Intervention and Regulatory Changes Risk. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) (which was passed into law in July 2010) significantly revised and expanded the rulemaking, supervisory and enforcement authority of federal bank, securities and commodities regulators. There can be no assurance that future regulatory actions including, but not limited to, those authorized by the Dodd-Frank Act will not adversely impact the Fund. Major changes resulting from legislative or regulatory actions could materially affect the profitability of the Fund or the value of investments made by the Fund or force the Fund to revise its investment strategy or divest certain of its investments. Any of these developments could expose the Fund to additional costs, taxes, liabilities, enforcement actions and reputational risk.

In addition, in October 2020, the SEC adopted new regulations governing the use of derivatives by registered investment companies. The Fund will be required to implement and comply with new Rule 18f-4 by the third quarter of 2022. Once implemented, Rule 18f-4 will impose limits on the amount of derivatives a fund can enter into, eliminate the asset segregation framework currently used by funds to comply with Section 18 of the 1940 Act, treat derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation and require funds whose use of derivatives is more than a limited specified exposure to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. These rules could have a substantial effect on the ability of the Fund to implement fully its investment strategy, as described herein, which may limit the Fund’s ability to achieve its objective.

High Yield Securities Risk. High yield securities, which are rated below investment grade and commonly referred to as “junk” bonds, are high risk, speculative investments that may cause income and principal losses for the Fund. They generally have greater credit risk, are less liquid and have more volatile prices than investment grade securities.

Interest Rate Risk. Interest rate risk is the risk that prices of fixed income securities generally increase when interest rates decline and decrease when interest rates increase. The Fund may lose money if short term or long term interest rates rise sharply or otherwise change in a manner not anticipated by the Sub-Adviser. It is likely there will be less governmental action in the near future to maintain low interest rates. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by the Fund. Recent and any future declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in a negative yield, and a decline in the Fund’s share price. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions for the Fund. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

Leveraging Risk. Investments in derivative instruments may give rise to a form of leverage. The Sub-Adviser may engage in speculative transactions which involve substantial risk and leverage. The use of leverage by the Sub-Adviser may increase the volatility of the Fund. These leveraged instruments may result in losses to the Fund or may adversely affect the Fund’s NAV or total return, because instruments that contain leverage are more sensitive to changes in interest rates. The Fund may also have to sell assets at inopportune times to satisfy its obligations in connection with such transactions.

Market Risk. The value of the Fund’s holdings and investment return will fluctuate based upon changes in the value of its investments. The market value of the Fund’s holdings is based upon the market’s perception of value and is not necessarily an objective measure of an investment’s value. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. U.S. and international markets have experienced significant periods of volatility in recent years and months due to a number of economic, political and global macro factors, including the impact of the coronavirus (COVID-19) global pandemic, which has resulted in a public health crisis, business interruptions, growth concerns in the U.S. and overseas, rising unemployment claims, changed travel and social behaviors and reduced consumer spending. Uncertainties regarding interest rates, political events, rising government debt in the U.S. and trade tensions have also contributed to market volatility.

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. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board of Trustees of The RBB Fund, Inc. (the “Company”) may determine to liquidate the Fund.

Non-Diversification Risk. The Fund is a non-diversified investment company, which means that more of the Fund’s assets may be invested in the securities of a single issuer than could be invested in the securities of a single issuer by a diversified investment company. This may make the value of the Funds’ shares more susceptible to certain risks than shares of a diversified investment company. As a non-diversified fund, the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

Underlying Funds Risk. The Fund may invest in shares of registered, closed-end or open-end investment companies and ETFs. Investments in ETFs are subject to the risks of the securities in which those investment companies invest. Your cost of investing in the Fund, as a fund that invests in Underlying Funds, may be higher than the cost of investing in a fund that only invests directly in individual securities. Fund shareholders will indirectly pay a portion of the operating costs of the Underlying Funds in addition to the expenses of the Fund’s own operation. These costs include management, brokerage, shareholder servicing and other operational expenses. Unlike shares of typical mutual funds or unit investment trusts, shares of ETFs are designed to be traded throughout the trading day, bought and sold based on market prices rather than NAV. An investment in an ETF generally presents the following risks: (i) the same primary risks as an investment in a conventional mutual fund (i.e., one that is not exchange-traded) that has the same investment objectives, strategies and policies; (ii) the risk that an ETF may fail to accurately track the market segment or index that underlies its investment objective; (iii) price fluctuation, resulting in a loss to the Fund; (iv) the risk that an ETF may trade at a discount to its NAV; (v) the risk that an active market for an ETF’s shares may not develop or be maintained; and (vi) the risk that an ETF may no longer meet the listing requirements of any applicable exchanges on which that ETF is listed.

Portfolio Turnover Risk. The Fund will not consider portfolio turnover rate a limiting factor in making investment decisions consistent with the Fund’s investment objective and policies. Therefore, it is possible that the Fund may experience high rates of portfolio turnover. High portfolio turnover will cause the Fund to incur higher brokerage commissions and transaction costs, which could lower the Fund’s performance. In addition to lower performance, high portfolio turnover could result in taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

Preferred Securities Risk. Preferred securities are contractual obligations that entail rights to distributions declared by the issuer, but the issuer may be permitted to defer or suspend distributions for a certain period of time. Preferred securities may pay fixed or adjustable rates of return. Preferred securities generally are subordinated to bonds and other debt instruments in a company’s capital structure and therefore will be subject to greater credit risk than those debt instruments. Furthermore, a company’s preferred securities generally pay dividends only after the company makes required payments to holders of its bonds and other debt. In addition, preferred securities are subject to other risks, such as having no or limited voting rights, being subject to special redemption rights, having distributions deferred or skipped, having floating interest rates or dividends, which may result in a decline in value in a falling interest rate environment, having limited liquidity, changing or unfavorable tax treatments and possibly being issued by companies in heavily regulated industries.

Quantitative Trading Strategy Risk. The Sub-Adviser uses quantitative methods to select Fund investments. Securities or other investments selected using quantitative methods may perform differently from the market as a whole or from their expected performance for many reasons, including factors used in building the quantitative analytical framework, the weights placed on each factor, and changing sources of market returns, among others. Any errors or imperfections in quantitative analyses or models, or in the data on which they are based, could adversely affect the ability of the Sub-Adviser to use such analyses or models effectively, which in turn could adversely affect the Fund’s performance. There can be no assurance that these methodologies will help the Fund to achieve its investment objective.

Sector Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies in the same sector of the market, an adverse economic, business or political development affecting that region or sector may affect the value of the Fund’s investments more, and the Fund’s investments may be more volatile, than if its investments were not so concentrated in such geographic region or economic sector.

U.S. Government Securities Risk. U.S. government securities are guaranteed only as to the timely payment of interest and the payment of principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates. Securities issued or guaranteed by U.S. government agencies and instrumentalities are supported by varying degrees of credit but generally are not backed by the full faith and credit of the U.S. government. No assurance can be given that the U.S. government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so.

Valuation Risk. The debt securities in which the Fund and Underlying Funds invest typically are valued by a pricing service utilizing a range of market-based inputs and assumptions, including readily available market quotations obtained from broker-dealers making markets in such instruments, cash flows and transactions for comparable instruments. There is no assurance that the Fund or Underlying Funds will be able to sell a portfolio security at the price established by the pricing service, which could result in a loss to the Fund. Pricing services generally price debt securities assuming orderly transactions of an institutional “round lot” size, but some trades may occur in smaller, “odd lot” sizes, often at lower prices than institutional round lot trades. Different pricing services may incorporate different assumptions and inputs into their valuation methodologies, potentially resulting in different values for the same securities. As a result, if the Fund or an Underlying Fund were to change pricing services, or if the Fund or an Underlying Fund’s pricing service were to change its valuation methodology, there could be a material impact, either positive or negative, on the Fund’s NAV.

rr_RiskNondiversifiedStatus

The Fund is a non-diversified investment company, which means that more of the Fund’s assets may be invested in the securities of a single issuer than could be invested in the securities of a single issuer by a diversified investment company. This may make the value of the Funds’ shares more susceptible to certain risks than shares of a diversified investment company. As a non-diversified fund, the Fund has a greater potential to realize losses upon the occurrence of adverse events affecting a particular issuer.

The returns in the bar chart are for Class I Shares. Class A Shares and Class C Shares would have substantially similar annual returns because each class of shares would have invested in the same portfolio of securities, and the annual returns would differ only to the extent that the classes have different expenses. The Fund’s Class A Shares are subject to a sales charge (load). Sales charges (loads) or account fees are not reflected in the bar chart and if these amounts were reflected, returns would be less than those shown.

Best and Worst Quarterly Performance (for the period reflected in the chart above):

Best Quarter: 15.02% (quarter ended June 30, 2020)
Worst Quarter: -17.51% (quarter ended March 31, 2020)

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. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. Portfolio turnover may vary from year to year, as well as within a year. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 88% of the average value of its portfolio.

“Other Expenses” for Class A Shares and Class C Shares, which had not commenced operations as of the date of this Prospectus, are estimated based on Class I Shares for the current fiscal year.

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $1,000,000 in Class I Shares or $10,000 in Class A Shares or Class C Shares of the Fund for the time periods indicated and that you sell your shares at the end of those periods. The Example also assumes that each year your investment has a 5% return and Fund operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests at least 80% of the value of its net assets, plus any borrowings for investment purposes, in equity securities. The Fund invests, under normal market conditions, significantly (ordinarily at least 40% - unless market conditions are not deemed favorable by the Adviser, in which case the Fund would invest at least 30%) in non-U.S. companies. The Fund defines non-U.S. companies as companies that (i) are organized under the laws of a foreign country; (ii) whose principal trading market is in a foreign country; or (iii) that have a majority of their assets or derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States.

The Fund’s investments in equity securities include, without limitation, common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock.The Fund’s investments will generally consist of securities, which may include common stocks, preferred stocks, warrants to acquire common stock, and securities convertible into common stock. The Fund purchases equity securities traded on registered exchanges or the over-the-counter market. The Fund may invest in securities of foreign issuers either directly or through depository receipts, including American Depository Receipts (“ADRs”). The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”). The Fund may invest in or have exposure to companies of any size, but primarily invests in large- and mid- capitalization companies.

The Adviser attempts to lower the Fund’s market risk by investing in equity securities that lower the overall volatility of the Fund’s portfolio as compared to global equity benchmarks. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. The Fund invests in stocks that exhibit less volatile stock price patterns, strengthening business metrics (i.e., earnings, debt, return on assets, competition, customers, industry, etc.) and quantitative factors such as earnings variability, leverage, volatility, price/book, price/cash flow, etc. In addition, the Adviser reviews the idiosyncratic risks associated with each stock if these risks are deemed elevated with increased downside risks, due to environmental, social and/or governance (“ESG”) issues. The Adviser selects

securities for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

The Fund may sell a stock if the Adviser identifies fundamental, ESG, or legal risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s 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. Different risks may be more significant at different times depending on market conditions or other factors.

■

Common Stock Risk. Investments in common stocks are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations.

■

Convertible Securities Risk. Securities that can be converted into common stock, such as certain securities and preferred stock, are subject to the usual risks associated with fixed income investments, such as interest rate risk and credit risk. In addition, because they react to changes in the value of the equity securities into which they will convert, convertible securities are also subject to the risks associated with equity securities.

■

Currency Risk. Investment in foreign securities also involves currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and which may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

■

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

■

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. The Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

■

Foreign Custody Risk. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain

countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

■

Foreign Securities Risk. International investing may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its NAV. Furthermore, certain foreign securities in which the Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Fund does not calculate its net asset value (“NAV”). As a result, the value of the Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

■

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. For the last fiscal year, the annual portfolio turnover rate of the Fund was lower than 100%, but the Fund’s portfolio turnover rate is expected to vary from year to year. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

■

Investment Companies and ETFs Risk. The Fund’s investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including ETFs, may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company or ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs maybe thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

■

Large-Cap Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

■

Low Volatility Risk. Although subject to the risks of common stocks, low volatility stocks are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility stocks may not produce investment exposure that has lower variability to changes in such stocks’ price levels. Investing in low volatility stocks may limit the Fund’s gains in rising markets.

■

Management Risk. The Fund is subject to the risk of poor stock selection. In other words, the individual stocks in the Fund may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

■

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

■

Mid-Cap Companies Risk. The stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

■

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

Warrants Risk. The purchase of warrants involves the risk that the Fund could lose the purchase value of a warrant if the right to subscribe to additional shares is not executed prior to the warrant’s expiration. Also, the purchase of warrants involves the risk that the effective price paid for the warrant added to the subscription price of the related security may exceed the value of the subscribed security’s market price such as when there is no movement in the level of the underlying security.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text]

rr_PortfolioTurnoverTextBlock

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 Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. For the fiscal year ended August 31, 2021, the Fund’s portfolio turnover rate was 178% of the average value of its portfolio.

rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees

Please note that the amount of Total Annual Fund Operating Expenses shown in the above table will differ from the “Financial Highlights” section of the Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as AFFE.

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Class I Shares of 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:

rr_StrategyNarrativeTextBlock

The Fund invests in securities of affiliated and unaffiliated open-end mutual funds and exchange-traded funds (“ETFs”) (collectively, “Underlying Funds”). The Fund may allocate assets across six categories of Underlying Funds: domestic equities, foreign equities (including emerging markets securities), domestic investment-grade bonds, domestic high yield bonds (also known as “junk bonds”), foreign investment-grade and high yield bonds, and money market funds.

Under normal circumstances, the Fund will invest primarily in Underlying Funds focusing on domestic equities and large capitalization foreign equities, a lesser amount in Underlying Funds focused on small and mid-capitalization foreign equities and emerging markets, and a small amount in Underlying Funds focused on domestic investment-grade bonds, domestic high yield bonds, foreign investment-grade and high yield bonds, and money market funds.

Summit Global Investments, LLC (the “Adviser”) attempts to lower the Fund’s market risk by investing in Underlying Funds that seek to lower the overall volatility of the Fund’s portfolio as compared to the S&P 500^® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In addition, the Adviser reviews the idiosyncratic risks associated with each Underlying Fund and if these risks are deemed elevated with increased downside risks the Adviser may make changes to the Underlying Funds. The Adviser selects Underlying Funds for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of volatility.

Some Underlying Funds may have processes that include environmental, social, and/or governance (“ESG”) considerations as part of their investment strategy. Not all Underlying Funds will include ESG as part of their investment strategy.

The Adviser may evaluate how an Underlying Fund uses proxy votes and access to corporate management. This process may include interviews with an Underlying Fund’s management and an examination of an Underlying Fund’s proxy voting records, prospectus and other reports. The methods that Underlying Funds use may vary.

The Fund may focus its investments in a particular industry or sector for the purpose of capitalizing on performance momentum in that industry or sector due to significant changes in market conditions or geopolitical conditions.

The Fund may sell an Underlying Fund if the Adviser identifies fundamental, ESG, legal or other risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

rr_RiskNarrativeTextBlock

Loss of money is a risk of investing in the Fund. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund’s 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. Different risks may be more significant at different times depending on market conditions or other factors.

■

Affiliated Fund Risk. Affiliated fund risk is the risk that the Adviser may select investments for the Fund based on its own financial interests rather than the Fund’s interests. The Adviser may be subject to potential conflicts of interest in selecting the Underlying Funds because the fees paid to the Adviser by some affiliated Underlying Funds may be higher than other Underlying Funds or the Underlying Funds may be in need of assets to enhance their appeal to other investors, liquidity and trading and/or to enable them to carry out their investment strategies. However, the Adviser is a fiduciary to the Fund and is legally obligated to act in the Fund’s best interest when selecting Underlying Funds.

■

Currency Risk. Underlying Funds that invest in foreign securities are subject to currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and that may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

■

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds, or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

■

Dividend-Paying Securities Risk. Underlying Funds that invest in dividend-paying securities may be subject to the risk that the company issuing such securities may fail and have to decrease or eliminate its dividend. In such an event, an Underlying Fund, and in turn the Fund, may not only lose the dividend payout but the stock price of the company may fall.

■

Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

■

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that some Underlying Funds may apply in selecting securities. Some Underlying Funds may screen out particular companies that do not meet their ESG criteria. This may affect the Underlying Funds’ and the Fund’s exposure to certain companies or industries and cause the Underlying Funds to forego certain investment opportunities. The Underlying Funds’ results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. Certain Underlying Funds may screen out companies that they believe may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Underlying Funds may invest in companies that do not reflect the beliefs and values of any particular investor.

■

Equity Risk. The Underlying Funds’ investments in common stock are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

■

Exchange-Traded Fund Risk. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

■

Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.

Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.

Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.

Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

■

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

■

Foreign Securities Risk. Underlying Funds that invest in foreign securities may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Investments in emerging market securities by Underlying Funds are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies.

■

Growth Risk. If an Underlying Fund adviser’s perceptions of a company’s growth potential are wrong, the securities purchased by that Underlying Fund may not perform as expected, thereby reducing the Underlying Fund’s and the Fund’s return.

■

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

■

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

■

Index Management Risk. To the extent the Fund invests in an Underlying Fund that is intended to track a target index, it is subject to the risk that the Underlying Fund may track its target index less closely. For example, an adviser to the Underlying Fund may select securities that are not fully representative of the index, and the Underlying Fund’s transaction expenses, and the size and timing of its cash flows, may result in the Underlying Fund’s performance being different than that of its index. Additionally, the Underlying Fund will generally reflect the performance of its target index even when the index does not perform well.

■

Industry or Sector Focus Risk. To the extent the Fund invests in Underlying Funds that focus their investments in a particular industry or sector, the Fund’s shares may be more volatile and fluctuate more than shares of a fund investing in a broader range of securities.

■

Large-Capitalization Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing an Underlying Fund and the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

■

Low Volatility Risk. Underlying Funds with investments in low volatility companies are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility Underlying Funds may not produce investment exposure that has lower variability to changes in market levels. Investing in low volatility Underlying Funds may limit the Fund’s gains in rising markets.

■

Management Risk. The Fund is subject to the risk of poor selection in Underlying Funds. The Underlying Funds may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

■

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in Underlying Funds that the Adviser believes will produce less volatility, there is no guarantee that the Underlying Funds will perform as expected. The prices of securities held by the Underlying Funds may decline in response to conditions affecting the general economy, overall market changes, local, regional or global political, social or economic instability, and currency, interest rate and commodity price fluctuations.

■

Mid-Capitalization Companies Risk. The stocks of mid-capitalization companies that the Underlying Funds may invest in may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

■

New Fund Risk. The Fund is new with a limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board may determine to liquidate the Fund.

■

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

■

Small-Capitalization Companies Risk. Small-cap companies that the Underlying Funds may invest in may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

■

Underlying Funds Risk. Investing in Underlying Funds may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The Fund’s investment performance and its ability to achieve its investment objective are directly related to the performance of the Underlying Funds in which it invests. The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

Summit Global Investments, LLC (the “Adviser”) attempts to lower the Fund’s market risk by investing in Underlying Funds that seek to lower the overall volatility of the Fund’s portfolio. The Fund seeks volatility between 60%-80% as compared to the S&P 500^® Index. Volatility is a statistical measurement of the magnitude of up and down fluctuations in the value of a financial instrument or index. In addition, the Adviser reviews the idiosyncratic risks associated with each Underlying Fund and if these risks are deemed elevated with increased downside risks the Adviser may make changes to the Underlying Funds. The Adviser selects Underlying Funds for the Fund that it anticipates will produce a portfolio with less volatility with more capital protection and consistent returns. While the Adviser attempts to manage the Fund’s volatility, there is no guarantee that the strategy will be successful or that the Fund’s portfolio will not experience periods of higher volatility.

Some Underlying Funds may have processes that include environmental, social, and/or governance (“ESG”) considerations as part of their investment strategy. Not all Underlying Funds will include ESG as part of their investment strategy.

The Adviser may evaluate how an Underlying Fund uses proxy votes and access to corporate management.

The methods that Underlying Funds use may vary.

The Fund may focus its investments in a particular industry or sector for the purpose of capitalizing on performance momentum in that industry or sector due to significant changes in market conditions or geopolitical conditions.

The Fund may sell an Underlying Fund if the Adviser identifies fundamental, ESG, legal or other risks and/or if the risk/return ranking declines due to increasing risk and/or decreasing return potential. The Fund may also decrease weight in an investment for risk control purposes.

Underlying Funds that invest in foreign securities are subject to currency risk associated with securities that trade or are denominated in currencies other than the U.S. dollar and that may be affected by fluctuations in currency exchange rates. An increase in the strength of the U.S. dollar relative to a foreign currency may cause the U.S. dollar value of an investment in that country to decline. Foreign currencies also are subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government controls.

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the Underlying Funds, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, the Underlying Funds, and the Underlying Funds’ third-party service providers and such third-party service providers may have limited indemnification obligations to the Fund, the Underlying Funds, or their respective investment advisers. Successful cyber-attacks or other cyber-failures or events affecting the Fund, the Underlying Funds, or third-party service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund or the Underlying Funds invest are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

■

Dividend-Paying Securities Risk. Underlying Funds that invest in dividend-paying securities may be subject to the risk that the company issuing such securities may fail and have to decrease or eliminate its dividend. In such an event, an Underlying Fund, and in turn the Fund, may not only lose the dividend payout but the stock price of the company may fall.

■

Emerging Markets Risk: Investment in emerging market securities involves greater risk than that associated with investment in foreign securities of developed foreign countries. These risks include volatile currency exchange rates, periods of high inflation, increased risk of default, greater social, economic and political uncertainty and instability, less governmental supervision and regulation of securities markets, weaker auditing and financial reporting standards, lack of liquidity in the markets, and the significantly smaller market capitalizations of emerging market issuers. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets.

■

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the ESG factors that some Underlying Funds may apply in selecting securities. Some Underlying Funds may screen out particular companies that do not meet their ESG criteria. This may affect the Underlying Funds’ and the Fund’s exposure to certain companies or industries and cause the Underlying Funds to forego certain investment opportunities. The Underlying Funds’ results may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. Certain Underlying Funds may screen out companies that they believe may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Underlying Funds may invest in companies that do not reflect the beliefs and values of any particular investor.

■

Equity Risk. The Underlying Funds’ investments in common stock are subject to market, economic and business risks that will cause their price to fluctuate over time. Therefore, an investment in the Fund may be more suitable for long-term investors who can bear the risk of these fluctuations. In the event an issuer is liquidated or declares bankruptcy, the claims of owners of bonds and preferred stock take precedence over the claims of those who own common stock.

■

Exchange-Traded Fund Risk. In addition to risks generally associated with investments in investment company securities, ETFs are subject to the following risks that do not apply to traditional mutual funds: (i) an ETF’s shares may trade at a market price that is above or below their net asset value (“NAV”); (ii) an active trading market for an ETF’s shares may not develop or be maintained; (iii) the ETF may employ an investment strategy that utilizes high leverage ratios; or (iv) trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are de-listed from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. Certain ETFs may be thinly traded and experience large spreads between the “ask” price quoted by a seller and the “bid” price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF’s shares could result in such shares trading at a significant premium or discount to their NAV.

■

Fixed Income Securities Risk. To the extent the Fund invests in Underlying Funds that invest in fixed income securities, the Fund will be subject to fixed income securities risks. While fixed income securities normally fluctuate less in price than stocks, there have been extended periods of increases in interest rates that have caused significant declines in fixed income securities prices. The values of fixed income securities may be affected by changes in the credit rating or financial condition of their issuers. Generally, the lower the credit rating of a security, the higher the degree of risk as to the payment of interest and return of principal.

Credit Risk. The issuer of a fixed income security may not be able to make interest and principal payments when due. Generally, the lower the credit rating of a security, the greater the risk that the issuer will default on its obligation. An Underlying Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor, or counterparty.

Duration Risk. Prices of fixed income securities with longer effective maturities are more sensitive to interest rate changes than those with shorter effective maturities.

Income Risk. The Fund’s income could decline due to falling market interest rates. In a falling interest rate environment, the Fund may be required to invest in Underlying Funds that invest their assets in lower-yielding securities. Because interest rates vary, it is impossible to predict the income or yield of the Fund for any particular period.

Interest Rate Risk. The value of the Fund or an Underlying Fund may fluctuate based upon changes in interest rates and market conditions. As interest rates increase, the value of an Underlying Fund’s income-producing investments may go down. For example, bonds tend to decrease in value when interest rates rise. Debt obligations with longer maturities typically offer higher yields, but are subject to greater price movements as a result of interest rate changes than debt obligations with shorter maturities. Changing interest rates may have unpredictable effects on the markets and an Underlying Fund’s investments and may also affect the liquidity of fixed income securities and instruments held by an Underlying Fund.

Prepayment Risk. The Fund may invest in Underlying Funds that invest in securities that are subject to fluctuations in yield, due to prepayment rates that may be faster or slower than expected.

Rating Risk. If a rating agency gives a debt security a lower rating, the value of the debt security will decline because investors will demand a higher rate of return.

■

Foreign Custody Risk. An Underlying Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Underlying Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Underlying Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

■

Foreign Securities Risk. Underlying Funds that invest in foreign securities may be subject to special risks, including, but not limited to, currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections and differences in taxation, auditing and other financial practices. Investments in emerging market securities by Underlying Funds are subject to higher risks than those in developed countries because there is greater uncertainty in less established markets and economies.

■

Growth Risk. If an Underlying Fund adviser’s perceptions of a company’s growth potential are wrong, the securities purchased by that Underlying Fund may not perform as expected, thereby reducing the Underlying Fund’s and the Fund’s return.

■

High Portfolio Turnover Risk. The risk that when investing on a shorter-term basis, the Fund may as a result trade more frequently and incur higher levels of brokerage fees and commissions and cause higher levels of current tax liability to shareholders of the Fund. A portfolio turnover rate of 100% is considered to be high. The Adviser may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

■

High-Yield Securities (“Junk Bond”) Risk. To the extent that a Fund invests in Underlying Funds that invest in high-yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”), the Fund may be subject to greater levels of interest rate and credit risk than funds that do not invest in such securities. Junk bonds are considered predominately speculative with respect to the issuer’s continuing ability to make principal and interest payments. An economic downturn or period of rising interest rates could adversely affect the market for these securities and reduce an Underlying Fund’s ability to sell these securities (liquidity risk). If the issuer of a security is in default with respect to interest or principal payments, the Underlying Fund may lose its entire investment, which will affect the Underlying Fund’s and the Fund’s return.

■

Index Management Risk. To the extent the Fund invests in an Underlying Fund that is intended to track a target index, it is subject to the risk that the Underlying Fund may track its target index less closely. For example, an adviser to the Underlying Fund may select securities that are not fully representative of the index, and the Underlying Fund’s transaction expenses, and the size and timing of its cash flows, may result in the Underlying Fund’s performance being different than that of its index. Additionally, the Underlying Fund will generally reflect the performance of its target index even when the index does not perform well.

■

Industry or Sector Focus Risk. To the extent the Fund invests in Underlying Funds that focus their investments in a particular industry or sector, the Fund’s shares may be more volatile and fluctuate more than shares of a fund investing in a broader range of securities.

■

Large-Capitalization Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing an Underlying Fund and the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

■

Low Volatility Risk. Underlying Funds with investments in low volatility companies are seen as having a lower risk profile than the overall markets. However, a portfolio comprised of low volatility Underlying Funds may not produce investment exposure that has lower variability to changes in market levels. Investing in low volatility Underlying Funds may limit the Fund’s gains in rising markets.

■

Management Risk. The Fund is subject to the risk of poor selection in Underlying Funds. The Underlying Funds may not perform as well as expected, and/or the Fund’s portfolio management practices may not work to achieve their desired result.

■

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in Underlying Funds that the Adviser believes will produce less volatility, there is no guarantee that the Underlying Funds will perform as expected. The prices of securities held by the Underlying Funds may decline in response to conditions affecting the general economy, overall market changes, local, regional or global political, social or economic instability, and currency, interest rate and commodity price fluctuations.

■

Mid-Capitalization Companies Risk. The stocks of mid-capitalization companies that the Underlying Funds may invest in may be subject to more abrupt or erratic market movements than stocks of larger, more established companies.

■

New Fund Risk. The Fund is new with a limited operating history and there can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board may determine to liquidate the Fund.

■

Opportunity Risk. As with all mutual funds, the Fund is subject to the risk of missing out on an opportunity because the assets necessary to take advantage of it are tied up in less advantageous investments.

■

Small-Capitalization Companies Risk. Small-cap companies that the Underlying Funds may invest in may be more volatile than, and not as readily marketable as, those of larger companies. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small-cap company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

■

Underlying Funds Risk. Investing in Underlying Funds may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The Fund’s investment performance and its ability to achieve its investment objective are directly related to the performance of the Underlying Funds in which it invests. The risk of owning an Underlying Fund generally reflects the risks of owning the underlying investments the Underlying Fund holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. In October 2020, the SEC adopted certain regulatory changes and took other actions related to the ability of an investment company to invest in another investment company. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text]

rr_PortfolioTurnoverTextBlock

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 Fund shares are held in a taxable account. These costs, which are not reflected in total annual fund operating expenses or in the Example, affect the Fund's performance. Portfolio turnover may vary from year to year, as well as within a year. During the most recent fiscal year, the Fund's portfolio turnover rate was 314% of the average value of its portfolio.

rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees

Please note that the amount of Total Annual Fund Operating Expenses shown in the above table will differ from the "Financial Highlights" section of the Prospectus, which reflects the operating expenses of the Fund and does not include indirect expenses such as AFFE.

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example below shows what you would pay if you invested $10,000 in the Fund over the various time periods indicated and then redeemed all of your shares at the end of those periods. The Example assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (taking into account the contractual expense limitation for the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its objective by investing under normal circumstances at least 80% of the net assets of the portfolio (including borrowings for investment purposes) in the stocks of U.S. companies with market capitalizations, at the time of purchase, that are within the trailing twelve-month range of the market capitalizations of those companies that are included in the Russell 2000^® Index (“Small Cap Stocks”). For purposes of this investment policy, stocks of U.S. companies are stocks that are listed on a securities exchange or market inside the United States. Because the Russell 2000^® Index (“Index”) is modified (“reconstituted”) regularly (usually each year) to replace companies that no longer qualify for inclusion in the Index due to, among other reasons, having market capitalizations that have grown too large, the Adviser uses the trailing twelve-month range of market capitalizations to mitigate the need to trade stocks in the portfolio due to Index reconstitution. Further, the Adviser will not sell from the portfolio any holdings that the Adviser believes are likely to appreciate more than the Index solely because the market capitalizations of such holdings cause the portfolio to hold less than 80% of its net assets within this range. As such, the Fund may, from time to time, hold less than 80% of its net assets within this range. The Fund attempts to achieve its objective by taking long positions in Small Cap Stocks that the Adviser believes are undervalued given their future earnings growth prospects. As part of its investment strategy, the Adviser will continue to invest in Small Cap Stocks that the Adviser believes will appreciate more than the Index. Shareholders will be notified by the Fund sixty days in advance of any change in this 80% policy. In seeking to achieve its principal investment strategies, the Fund will engage in trading of portfolio securities that will likely result in a high portfolio turnover rate.

rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The Fund's 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. Different risks may be more significant at different times depending on market conditions or other factors.

•

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cyber security risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

•

Environmental, Social and Governance (“ESG”) Investing Risk. ESG investing risk is the risk stemming from the ESG factors that the Fund may apply in selecting securities. The Fund seeks to screen out companies that it believes may have higher downside risk and lower ESG ratings, but investors may differ in their views of ESG characteristics. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s returns may be lower than other funds that do not use ESG ratings and/or screen out certain companies or industries. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

•

Equity Stock Risk. Common stocks may decline over short or even extended periods of time. Equity markets tend to be cyclical; there are times when stock prices generally increase, and other times when they generally decrease. Therefore, you could lose money by investing in the Fund.

•

Growth Stock Risk. Growth stocks are typically priced higher than other stocks, in relation to earnings and other measures, because investors believe they have more growth potential. This potential may or may not be realized and, if it is not realized, may result in a loss to the Fund. Growth stock prices also tend to be more volatile than the overall market. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund's return may be adversely affected during a market downtown and when growth stocks are out of favor.

•

Investment Companies and Exchange-Traded Funds (“ETFs”) Risk. The Fund's investment performance may be affected by the investment performance of the underlying funds in which the Fund may invest. Investing in other investment companies, including ETFs, may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. The risk of owning an investment company or ETF generally reflects the risks of owning the underlying investments the investment company an ETF holds. The Fund may incur brokerage fees in connection with its purchase of ETF shares. Certain ETFs may be thinly traded and experience large spreads between the "ask" price quoted by a seller and the "bid" price offered by a buyer. The existence of extreme market volatility or potential lack of an active trading market for an ETF's shares could result in such shares trading at a significant premium or discount to their NAV.

•

Market Risk. The net asset value ("NAV") of the Fund will change with changes in the market value of its portfolio positions. Investors may lose money. The value of investments held by the Fund may increase or decrease in response to economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. Although the Fund will invest in stocks the Adviser believes will produce less volatility, there is no guarantee that the stocks will perform as expected.

•

Portfolio Turnover Risk. The Fund may frequently trade its portfolio holdings. High portfolio turnover will cause the Fund to incur higher brokerage commissions and other transaction costs, which could lower the Fund's performance. In addition to lower performance, high portfolio turnover could result in higher taxable capital gains. A portfolio turnover rate of 100% is considered to be high.

•

Small Cap Risk. The Fund will invest in Small Cap Stocks that may be more volatile than investments in issuers with larger market capitalizations. Issuers of Small Cap Stocks are not as diversified in their business activities as issuers with larger market capitalizations and are more susceptible to changes in the business cycle. Small companies may also have limited product lines, markets or financial resources and may be dependent on relatively small or inexperienced management groups. Additionally, the trading volume of small company securities may make them more difficult to sell than those of larger companies. Moreover, the lack of an efficient market for the securities may make them difficult to value.

•

Value Stock Risk. Although the Fund will invest in stocks that the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower. Because different types of stocks go out of favor with investors depending on market and economic conditions, the Fund’s return may be adversely affected during a market turndown and when value stocks are out of favor.

Other Expenses, New Fund, Based on Estimates [Text]

rr_PortfolioTurnoverTextBlock

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 Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Fund’s performance. During the fiscal period from the Fund’s inception on March 15, 2021 through August 31, 2021, the Fund’s portfolio turnover rate was 180% of the average value of its portfolio.

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: (1) your investment has a 5% return each year, and (2) 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:

rr_StrategyNarrativeTextBlock

The Fund is an actively managed exchange-traded fund (“ETF”) that will invest, under normal circumstances at least 80% of the value of its net assets (plus the amount of any borrowings for investment purposes) in exchange-traded equity securities of U.S. large capitalization issuers that meet environmental, social, and governance (“ESG”) standards, as determined by the Fund’s sub-adviser, Stance Capital, LLC (the “Sub-Adviser”). The Fund currently considers companies within the Russell 1000^® Index and S&P 500^® Index to be large capitalization issuers.

In identifying investments for the Fund, the Sub-Adviser utilizes three independent processes. First, the Sub-Adviser applies a rules-based ESG methodology which seeks to identify the top 50% from each industry and sub-industry in the universe of large capitalization companies. Companies who have exclusively or primarily engaged in weapons, tobacco, or thermal coal are generally excluded from consideration. The remaining universe is then quantitatively scored against industry group peers on up to 21 sustainability-related key performance indicators ("KPIs") such as energy productivity, carbon intensity, water dependence, waste profile and KPIs relating to governance, including capacity to innovate, unfunded pension fund liabilities, chief executive officer/average worker pay, safety performance, employee turnover, leadership diversity, percentage tax paid, and percent of bonus linked to sustainability performance. The securities in the top 50% may be retained. The Sub-Adviser utilizes data feeds from third parties that the Sub-Adviser considers, in its sole discretion, as trustworthy and/or have expertise in specific KPI areas. The current primary external data source is Corporate Knights Research, but such firm or firms may change in the Sub-Adviser’s discretion. Corporate Knights Research is based in Toronto, and is a leading media firm in Canada focused on climate risk. For over 20 years they have published an annual ranking of the most sustainable companies in the world. Their methodology is rules-based and forms the foundation of the Sub-Adviser’s approach to ESG scoring. Second, the Sub-Adviser applies a machine learning model which uses financial, risk, and other factors to identify companies that are most likely to outperform both in absolute returns and in risk adjusted returns over the next quarter. In the final process, the portfolio is optimized to minimize tail risk and maximize diversification The Sub-Adviser generally re-balances the portfolio quarterly. Positions are sold quarterly if the Sub-Adviser decides they are no longer optimal in the portfolio.

The Fund’s investment portfolio is focused, generally composed of at least 30 investment positions.

While investing in a particular sector is not a principal investment strategy of the Fund, its portfolio may be significantly invested in a sector as a result of the portfolio management decisions made pursuant to its principal investment strategy. While the Fund does not place any restrictions on its level of sector concentration, it will limit its investments in industries within any particular sector to less than 25% of the Fund’s total assets. On each rebalancing date, investments within a particular sector will also be capped at up to twice the weight of the sector within the S&P 500 Index.

The Fund intends to continue to qualify each year for treatment as a regulated investment company (“RIC”) under Subchapter M of Subtitle A, Chapter 1, of the Internal Revenue Code of 1986, as amended (the “Code”).

Semi-Transparent Actively-Managed ETF with Portfolio Reference Basket Structure. The Fund is an actively-managed, semi-transparent ETF. Unlike traditional ETFs, which generally publish their portfolio holdings on a daily basis, the Fund discloses a portfolio transparency substitute—the “Portfolio Reference Basket”—and certain related information about the Portfolio Reference Basket relative to the Fund’s actual portfolio (“Actual Portfolio”) holdings (the “Portfolio Reference Basket Disclosures”), which are intended to help keep the market price of the Fund’s Shares trading at or close to the underlying net asset value (“NAV”) per Share of the Fund. While the Portfolio Reference Basket includes all of the Fund’s holdings, it is not the Fund’s Actual Portfolio because the holdings will be weighted differently, subject to a minimum weightings overlap of 90% with the Fund’s Actual Portfolio at the beginning of each trading day. The Fund also discloses the maximum deviation between the weightings of the specific securities in the Portfolio Reference Basket and the weightings of those specific securities in the Actual Portfolio, as well as between the weighting of the respective cash positions (the “Guardrail Amount”). The Guardrail Amount is intended to ensure that no individual security in the Portfolio Reference Basket will be overweighted or underweighted by more than the publicly disclosed percentage when compared to the actual weighting of each security within the Actual Portfolio as of the beginning of each trading day. The Fund is actively-managed and does not seek to track an index.

rr_RiskNarrativeTextBlock

The value of the Fund’s investments may decrease, which will cause the value of the Fund’s Shares to decrease. As a result, you may lose money on your investment in the Fund, and there can be no assurance that the Fund will achieve its investment objective. Each risk summarized below is a principal risk of investing in the Fund and different risks may be more significant at different times depending upon market conditions or other factors.

●

Portfolio Reference Basket Structure Risk. Unlike traditional ETFs that provide daily disclosure of their portfolio holdings, the Fund discloses daily the identities of all portfolio holdings, but not the exact quantities or weightings. Instead, the Fund discloses a Portfolio Reference Basket generated each day by a proprietary algorithmic process that is designed to closely track the daily performance of the Fund’s Actual Portfolio on any given trading day. Although the Portfolio Reference Basket and Portfolio Reference Basket Disclosures are intended to provide authorized participants and other market participants with enough information to allow them to engage in effective arbitrage transactions that will help keep the market price of the Shares trading at or close to the underlying NAV per Share of the Fund, there is a risk that market prices will vary significantly from the underlying NAV of the Fund, which may be heightened during periods of market disruption or volatility. Similarly, Shares may trade at a wider bid/ask spread than shares of traditional ETFs and may therefore be more costly for investors to trade, which may be heightened during periods of market disruption or volatility. Additionally, the Portfolio Reference Basket structure itself may result in additional trading costs because the Fund may receive or deliver holdings in different weightings on any given day than the weightings of the Fund’s Actual Portfolio, which may result in portfolio turnover, and related transaction costs, to re-align the Actual Portfolio with the Fund’s intended investment strategy. In addition, although the Fund seeks to benefit from keeping its Actual Portfolio secret, market participants may attempt to use the Portfolio Reference Basket to identify the Fund’s trading strategy, which if successful, could result in such market participants engaging in certain predatory practices, such as front-running the Fund’s trading activity or free-riding on the Fund’s investment strategy, that may potentially harm the Fund and its shareholders. There can be no assurance that the Portfolio Reference Basket structure will operate as intended. The Portfolio Reference Basket structure is novel and not yet proven as an effective arbitrage mechanism. The effectiveness of the Portfolio Reference Basket structure as an arbitrage mechanism is contingent upon, among other things, the effectiveness of the proprietary algorithmic process employed to create a Portfolio Reference Basket that performs in a manner substantially identical to the performance of the Fund’s Actual Portfolio and the willingness of authorized participants and other market participants to trade based on the Portfolio Reference Basket. In the event that the Portfolio Reference Basket structure does not result in effective arbitrage opportunities in the Fund Shares, the Fund may exhibit wider premiums/discounts, bid/ask spreads and tracking error than traditional ETFs. For at least the first three years after launch of the Fund, if the tracking error (relative to the Actual Portfolio) exceeds 1%, or if, for 30 or more days in any quarter or 15 days in a row, the absolute difference between either the closing price or the mid-point of the highest bid and lowest offer at the time of calculation of the NAV (the “Bid/Ask Price”), on one hand, and NAV, on the other, exceeds 2.00% or the bid/ask spread exceeds 2.00%, the Adviser will recommend appropriate remedial measures to the Board of Directors (the “Board”) of the Company for its consideration, which may include, but are not limited to, liquidation of the Fund.

Authorized Participants, Market Makers and Liquidity Providers Concentration Risk. Only an Authorized Participant may engage in creation or redemption transactions directly with the Fund. The Fund has a limited number of financial institutions that are institutional investors and 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, Fund Shares may trade at a material discount to NAV and possibly face trading halts or 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. These events, among others, may lead to the Fund Shares trading at a premium or discount to NAV. Thus, you may pay more (or less) than the NAV when you buy Shares of the Fund in the secondary market, and you may receive less (or more) than NAV when you sell those Shares in the secondary market. A diminished market for an ETF’s shares substantially increases the risk that a shareholder may pay considerably more or receive significantly less than the underlying value of the ETF shares bought or sold. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares. Further, the Fund is utilizing a novel and unique structure, which may affect the number of entities willing to act as APs, market makers and/or liquidity providers.

○

Cash Transactions Risk. Unlike traditional ETFs, the securities in the Fund’s basket of securities exchanged for a Creation Unit will not correspond pro rata to the positions in the Fund’s portfolio, and the Fund may effect its creations and redemptions partially or wholly for cash rather than on an in-kind basis. Because of this, the Fund may incur costs such as brokerage costs or be unable to realize certain tax benefits associated with in-kind transfers of portfolio securities that may be realized by other ETFs. These costs may decrease the Fund’s NAV to the extent that the costs are not offset by a transaction fee payable by an AP. Shareholders may be subject to tax on gains they would not otherwise have been subject to and/or at an earlier date than if the Fund had effected redemptions wholly on an in-kind basis.

○

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the NYSE Arca, Inc. (the “Exchange”), there can be no assurance that an active or liquid trading market for them will develop or be maintained. In addition, trading in Shares on the Exchange may be halted. Trading may be halted because of market conditions or for reasons that, in the view of the Exchange, make trading in the Fund inadvisable. These may include: (a) the extent to which trading is not occurring in the securities and/or the financial instruments composing the Portfolio Reference Basket and/or Actual Portfolio; or (b) whether other unusual conditions or circumstances detrimental to the maintenance of a fair and orderly market are present. During periods of market stress, 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). This risk is heightened in times of market volatility or periods of steep market declines.

○

Shares May Trade at Prices Other Than NAV Risk. As with all ETFs, Shares may be bought and sold in the secondary market at market prices. Although the Portfolio Reference Basket structure is intended to provide market participants with enough information to allow for an effective arbitrage mechanism that will help to keep the market price of the Fund’s Shares at or close to the Fund’s NAV, there is a risk that market prices for Fund Shares will vary significantly from the Fund’s NAV. This risk is heightened in times of market volatility or periods of steep market declines. This risk may be greater for the Fund than for traditional ETFs that disclose their full portfolio holdings on a daily basis because the publication of the Portfolio Reference Basket does not provide the same level of transparency as the daily publication of the actual portfolio by a traditional ETF. This could cause the Fund’s Shares to have wider bid/ask spreads and larger premiums/discounts than traditional ETFs using the same or similar investment strategies.

○

Limitations of Intraday Indicative Value (IIV) Risk. The Exchange or a market data vendor intends to disseminate the approximate per share value of the Fund’s Portfolio Reference Basket every 15 seconds (the ‘‘intraday indicative value’’ or ‘‘IIV’’). The IIV should not be viewed as a ‘‘real-time’’ update of the NAV per share of the Fund because (i) the IIV is not be calculated in the same manner as the NAV, which is computed once a day, generally at the end of the business day, (ii) the calculation of NAV may be subject to fair valuation at different prices than those used in the calculations of the IIV, (iii) unlike the calculation of NAV, the IIV does not take into account Fund expenses, and (iv) the IIV is based on the Portfolio Reference Basket and not on the Fund’s Actual Portfolio. The Fund, the Adviser and their affiliates are not involved in, or responsible for, any aspect of the calculation or dissemination of the Fund’s IIV, and the Fund, the Adviser and their affiliates do not make any warranty as to the accuracy of these calculations.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser or sub-advisers, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser and sub-advisers have limited ability to prevent or mitigate cyber security incidents affecting third-party service providers. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders.

●

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 losses and may limit or stop purchases of the Fund.

●

Environmental, Social and Governance Investing Risk. ESG investing risk is the risk stemming from the environmental, social and governance factors that the Fund applies in selecting securities. The Fund intends to invest in companies with measurable high ESG ratings relative to their sector peers, and screen out particular companies that do not meet its ESG criteria. This may affect the Fund’s exposure to certain companies or industries and cause the Fund to forego certain investment opportunities. The Fund’s returns may be lower than other funds that do not seek to invest in companies based on ESG ratings and/or screen out certain companies or industries. The Fund seeks to identify companies that it believes may have higher ESG ratings, but investors may differ in their views of ESG characteristics. As a result, the Fund may invest in companies that do not reflect the beliefs and values of any particular investor.

●

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.

●

Large-Cap Companies Risk. The stocks of large capitalization companies as a group could fall out of favor with the market, causing the Fund to underperform investments that focus solely on small- or medium- capitalization stocks.

●

Management Risk. The Fund is subject to management risk as an actively-managed investment portfolio. The Adviser’s investment approach may fail to produce the intended results.

●

Market Risk. The trading prices of equity securities and other instruments fluctuate in response to a variety of factors including economic, political, financial, public health crises (such as epidemics or pandemics) or other disruptive events (whether real, expected or perceived) in the U.S. and global markets. The Fund’s NAV and market price may fluctuate significantly in response to these and other factors. As a result, an investor could lose money over short or long periods of time.

●

Model Risk. The Fund seeks to pursue its investment objective by using proprietary models that incorporate quantitative analysis. Investments selected using these models may perform differently than as forecasted due to the factors incorporated into the models and the weighting of each factor, changes from historical trends, and issues in the construction and implementation of the models (including, but not limited to, software issues and other technological issues). There is no guarantee that the Sub-Adviser’s use of these models will result in effective investment decisions for the Fund. The information and data used in the models may be supplied by third parties. Inaccurate or incomplete data may limit the effectiveness of the models. In addition, some of the data that the models use may be historical data, which may not accurately predict future market movement. There is a risk that the models will not be successful in selecting investments or in determining the weighting of investment positions that will enable the Fund to achieve its investment objective.

●

New Fund Risk. The Fund is a recently organized, diversified management investment company with a limited operating history. As a result, prospective investors have a limited track record on which to base their investment decision. In addition, there can be no assurance that the Fund will grow to, or maintain, an economically viable size, in which case the Board may determine to liquidate the Fund.

●

Portfolio Turnover Risk. A high portfolio turnover rate (100% or more on an annualized basis) increases the Fund’s transaction costs (including brokerage commissions and dealer costs), which adversely impacts the Fund’s performance. Higher portfolio turnover may result in the realization of more short-term capital gains than if the Fund had lower portfolio turnover.

●

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. While the Fund may not concentrate in any one industry, the Fund may invest without limitation in any particular market sector.

○

Healthcare Sector Risk. Companies in the health care sector are subject to extensive government regulation and their profitability can be significantly affected by regulatory changes. Other risk factors include rising costs of medical products and services, pricing pressure and limited product lines, loss or impairment of intellectual property rights and litigation regarding product or service liability.

○

Consumer Discretionary Sector Risk. Companies in the consumer discretionary sector can be significantly affected by the performance of the overall economy, interest rates, competition, consumer confidence and spending, and changes in demographics and consumer tastes.
