The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year ended August 31, 2022, the Fund’s portfolio turnover rate was 0% of the average value of its portfolio. In accordance with industry practice, derivative instruments and instruments with a maturity of one year or less at the time of acquisition are excluded from the calculation of the portfolio turnover rate, which leads to the 0% portfolio turnover rate reported above. If those instruments were included in the calculation, the Fund would have a high portfolio turnover rate.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by allocating its assets between a “Managed Futures” strategy and a “Fixed Income” strategy.

The Managed Futures strategy will be achieved by the Fund investing a portion of its assets in Abbey Capital Onshore Series LLC, a wholly-owned and controlled Delaware series limited liability company (the “Onshore Subsidiary”) and up to 25% of its total assets in Abbey Capital Master Offshore Fund Limited, a wholly-owned and controlled subsidiary of the Fund organized under the acts of the Cayman Islands (the “Cayman Subsidiary”). The Cayman Subsidiary will in turn invest all or substantially all of its assets in segregated portfolios of Abbey Capital Offshore Fund SPC (the “SPC” and, together with the Onshore Subsidiary and the Cayman Subsidiary, the “Subsidiaries”), a wholly-owned and controlled segregated portfolio company incorporated under the acts of the Cayman Islands. The Cayman Subsidiary will serve solely as an intermediate entity through which the Fund will invest in the SPC. The Cayman Subsidiary makes no independent investment decisions and has no investment or other discretion over the Fund’s investable assets. The Adviser may allocate assets of the SPC and the Onshore Subsidiary to multiple Managed Futures portfolios (the “Segregated Portfolios”) that include investment styles or sub-strategies such as (i) trend following, (ii) discretionary, fundamentals-based investing with a focus on macroeconomic analysis, (iii) strategies that pursue both fundamental and technical trading approaches, (iv) other specialized approaches to specific or individual market sectors such as equities, interest rates, metals, agricultural and soft commodities, and (v) systematic trading strategies which incorporate technical and fundamental variables.

The Managed Futures strategy investments are designed to achieve capital appreciation in the financial and commodities futures markets. The Adviser intends to allocate the assets of the SPC and the Onshore Subsidiary to one or more Trading Advisers to manage in percentages determined at the discretion of the Adviser. Each Trading Adviser will manage one or more of its own Segregated Portfolios. Each Trading Adviser invests according to a Managed Futures strategy in one or a combination of (i) options, (ii) futures, (iii) forwards, (iv) spot contracts, or (v) swaps, including total return swaps, each of which may be tied to (i) commodities, (ii) financial indices and instruments, (iii) foreign currencies, or (iv) equity indices. All commodities futures and commodities-related investments will be made in the Segregated Portfolios of the SPC. Each current Trading Adviser is registered with the CFTC as a Commodity Trading Advisor (“CTA”). Trading Advisers that are not registered with the SEC as investment advisers provide advice only regarding matters that do not involve securities.

The Fixed Income strategy invests the Fund’s assets primarily in investment grade fixed income securities (of all durations and maturities) in order to generate interest income and capital appreciation, which may add diversification to the returns generated by the Fund’s Managed Futures strategy.

The Fund’s Adviser seeks returns, in part, by (i) using Managed Futures strategy investments that are not expected to have returns that are highly correlated to the broad equity market, and (ii) through actively managed Fixed Income strategy investments that are not expected to have returns that are highly correlated to the broad equity market or the Managed Futures strategy. The Adviser believes that utilizing non-correlated strategies may mitigate losses in generally declining markets. However, there can be no assurance that losses will be avoided. Investment strategies that have historically been non-correlated or demonstrated low correlations to one another or to major world financial market indices may become correlated at certain times, such as during a liquidity crisis in global financial markets.

The trading strategies employ several different trading styles using different research and trading methodologies, in a wide range of global financial and commodity markets operating over multiple time frames. Many of the styles use systematic, automated trading systems, using a combination of mathematical, statistical, technical analysis, pattern recognition and macroeconomic models aimed at profiting from market trends of different durations. Trading Advisers may use discretionary approaches aimed at identifying value investments and turning points in trends. All Trading Advisers utilize a disciplined approach to risk management. The Adviser and Trading Advisers from time to time will employ hedging techniques. Key principles of the Fund’s sell discipline include predetermined relative-value objectives for sectors, issuers and specific securities, pricing performance or fundamental performance that varies from expectations, deteriorating fundamentals, overvaluation and alternative investments offering the opportunity to achieve more favorable risk-adjusted returns.

The markets traded include bonds, money markets, foreign exchange markets and commodity markets. Most of the trading is done in derivative markets, usually listed futures markets, but some trading in cash markets may take place when this is the most effective way to enter or exit a trading position. Both long and short positions will be taken in all markets traded. Contracts are positioned either long or short based on various characteristics related to their prices. For example, the Fund may short a particular underlying security or instrument if the Adviser or a Trading Adviser believes the price of the underlying security or instrument will decrease. The Fund invests in U.S. and non-U.S. markets and in developed and emerging markets.

As much of the trading within the Fund is in futures markets, the Fund is likely to have cash balances surplus to margin requirements. The cash portfolio will be invested on a short-term, highly liquid, basis, to meet margin calls on the futures positions.

The Fund is “non-diversified” for purposes of the Investment Company Act of 1940, as amended, (the “1940 Act”) which means that the Fund may invest in fewer securities at any one time than a diversified fund. The Fund may not invest more than 15% of its net assets in illiquid investments. The Fund’s investments in certain derivative instruments and its short selling activities involve the use of leverage.

Generally, the SPC invests primarily in commodity futures but it may also invest in financial futures, options, forwards, spot contracts and swap contracts, fixed income securities, pooled investment vehicles, including those that are not registered pursuant to the 1940 Act and other investments intended to serve as margin or collateral for the SPC’s derivative positions. The Onshore Subsidiary only invests in financial futures, options, forwards, spot contracts and swap contracts, fixed income securities, pooled investment vehicles, including those that are not registered pursuant to the 1940 Act, and other investments intended to serve as margin or collateral for derivative positions. The Fund invests in the SPC in order to gain exposure to the commodities markets within the limitations of the federal tax laws, rules and regulations that apply to regulated investment companies. Unlike the Fund and Onshore Subsidiary, the SPC may invest without limitation in commodity-linked derivatives. The Fund complies with Section 8 and Section 18 of the 1940 Act, governing investment policies and capital structure and leverage, respectively, on an aggregate basis with the Subsidiaries. The Subsidiaries also comply with Section 17 of the 1940 Act relating to affiliated transactions and custody.

In addition, to the extent applicable to the investment activities of the Subsidiaries, the Subsidiaries are subject to the same fundamental investment restrictions and will follow the same compliance policies and procedures as the Fund. Unlike the Fund, none of the Subsidiaries will seek to qualify 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”). The Fund is, directly or indirectly, the sole shareholder of each Subsidiary and does not expect shares of the Subsidiaries to be offered or sold to other investors.

Risk Narrative [Text Block]

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.

The principal risk factors affecting shareholders’ investments in the Fund (and, indirectly, in the Subsidiaries) are set forth below.

● Commodity Sector Risk: Exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as drought, floods, weather, livestock disease, pandemics, embargoes or other trade barriers, tariffs and international economic, political and regulatory developments. The prices of energy, industrial metals, precious metals, agriculture and livestock sector commodities may fluctuate widely due to factors such as changes in value, supply and demand and governmental regulatory policies. The commodity-linked securities in which the Fund invests may be issued by companies in the financial services sector, and events affecting the financial services sector may cause the Fund’s Share value to fluctuate.

● Counterparty Risk: Counterparty risk is the risk that the other party(s) to an agreement or a participant to a transaction, such as a broker or the futures commission merchant, 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 Risk: Credit risk refers to the possibility that the issuer of the security will not be able to make principal and interest 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.

● 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. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Fund than if it had not engaged in these contracts.

● 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 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 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.

● Derivatives Risk: The Fund’s investments in derivative instruments including options, forward currency exchange contracts, 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. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

● Fixed Income Securities Risk: Fixed income securities in which the 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 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 Investments Risk: International investing may be subject to special risks, including 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. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders. Foreign securities in which the Fund invests may be traded in markets that close before the time that the Fund calculates its net asset value (“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 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.

● Forward and Futures Risk: The successful use of forward and futures contracts draws upon the Adviser’s and Trading Advisers’ skill and experience with respect to such instruments and are subject to special risk considerations. The primary risks associated with the use of futures contracts are (a) the imperfect correlation between the change in market value of instruments held by the Fund and the price of the forward or futures contract; (b) possible lack of a liquid secondary market, and possible regulatory position limits and restrictions, for a forward or futures contract and the resulting inability to close a forward or futures contract when desired; (c) losses caused by unanticipated market movements, which are potentially unlimited; (d) the Adviser’s and Trading Advisers’ inability to predict correctly the direction of securities prices, interest rates, currency exchange rates and other economic factors; (e) the possibility that the counterparty will default in the performance of its obligations; and (f) if the Fund has insufficient cash, it may have to sell securities from its portfolio to meet daily variation margin requirements, and the Fund may have to sell securities at a time when it may be disadvantageous to do so.

● Government Intervention and Regulatory Changes: 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.

On August 19, 2022, new SEC regulations governing the use of derivatives by registered investment companies became effective. Rule 18f-4 imposes limits on the amount of derivatives a fund can enter into, eliminates the asset segregation framework previously used by funds to comply with Section 18 of the 1940 Act, treats derivatives as senior securities so that a failure to comply with the limits would result in a statutory violation, and requires the Fund to establish and maintain a comprehensive derivatives risk management program and appoint a derivatives risk manager. Rule 18f-4. Rule 18f-4 may require the Fund to observe more stringent asset coverage and related requirements than were previously imposed by the 1940 Act.

● Hedging Transactions Risk: The Adviser and Trading Advisers from time to time employ various hedging techniques. The success of the Fund’s hedging strategy will be subject to the Adviser’s and Trading Advisers’ ability to correctly assess the degree of correlation between the performance of the instruments used in the hedging strategy and the performance of the investments in the portfolio being hedged. Since the characteristics of many securities change as markets change or time passes, the success of the Fund’s hedging strategy will also be subject to the Adviser’s and Trading Advisers’ ability to continually recalculate, readjust, and execute hedges in an efficient and timely manner. For a variety of reasons, the Adviser and Trading Advisers may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Such imperfect correlation may prevent the Fund from achieving the intended hedge or expose the Fund to risk of loss. In addition, it is not possible to hedge fully or perfectly against any risk, and hedging entails its own cost.

● 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 in the Fund.

● 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 Adviser and Trading Advisers. 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. 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. Certain countries and regulatory bodies may use negative interest rates as a monetary policy tool to encourage economic growth during periods of deflation. In a negative interest rate environment, debt instruments may trade at negative yields, which means the purchaser of the instrument may receive at maturity less than the total amount invested.

● Leveraging Risk: Investments in derivative instruments may give rise to a form of leverage. Trading Advisers may engage in speculative transactions which involve substantial risk and leverage, such as making short sales. The use of leverage by the Adviser and Trading Advisers 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.

● Management Risk: The Fund is subject to the risk of poor investment selection. In other words, the individual investments of 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.

● Manager Risk: If the Adviser and Trading Advisers make poor investment decisions, it will negatively affect the Fund’s investment performance.

● Market Risk: The NAV of the Fund will change with changes in the market value of its portfolio positions. 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. Investors may lose money.

● Multi-Manager Dependence Risk: The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Trading Advisers and to allocate assets to those Trading Advisers and on each Trading Adviser’s ability to execute the relevant strategy and select investments for the Fund and the Subsidiaries. The Trading Advisers’ investment styles may not always be complementary, which could adversely affect the performance of the Fund.

● New Adviser Risk: The Trading Advisers may be newly registered or not registered with the SEC and/or have not previously managed a mutual fund. Accordingly, investors in the Fund bear the risk that a Trading Adviser’s inexperience may limit its effectiveness.

● Non-Diversification Risk: The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

● Options Risk: Purchasing and writing put and call options are highly specialized activities and entail greater than ordinary investment risks. The Fund may not fully benefit from or may lose money on an option if changes in its value do not correspond as anticipated to changes in the value of the underlying securities.

● Quantitative Trading Strategies Risk: The Adviser and Trading Advisers may use quantitative methods to select 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 Adviser or a Trading 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.

● Short Sales Risk: Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. The Fund may engage in short sales that are either “uncovered” or “against the box.” A short sale is “against the box” if at all times during which the short position is open, the Fund owns at least an equal amount of the securities or securities convertible into, or exchangeable without further consideration for, securities of the same issue as the securities that are sold short. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

● Subsidiary Risk: By investing in the Subsidiaries, the Fund is indirectly exposed to the risks associated with each Subsidiary’s investments. The derivatives and other investments held by the Subsidiaries are generally similar to those that are permitted to be held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund. The Subsidiaries are not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, are not subject to all the investor protections of the 1940 Act. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiaries to continue to operate as they currently do and could adversely affect the Fund.

● Tax Risk: In order to qualify as a RIC, the Fund must meet certain requirements regarding the source of its income, the diversification of its assets and the distribution of its income. Under the test regarding the source of a RIC’s income, at least 90% of the gross income of the RIC each year must be qualifying income, which consists of dividends, interest, gains on investment assets and other categories of investment income. Treasury Regulations provide that income from a foreign subsidiary that is a controlled foreign corporation is qualifying income for purposes of the Fund remaining qualified as a RIC for U.S. federal income tax purposes. Notwithstanding the treatment of controlled foreign corporations in the regulations, the Internal Revenue Service (“IRS”) may take the position that income earned by the Fund through the Cayman Subsidiary may not be qualifying income because of its investment in commodities. Additionally, the IRS may take the position that certain commodity-linked structured notes may not be qualifying income. A recharacterization of income from the Cayman Subsidiary or commodity-linked structured notes could cause the Fund to fail to qualify as a RIC. If the Fund were to fail to qualify as a RIC and became subject to federal income tax, shareholders of the Fund would be subject to diminished returns. Changes in the laws or acts of the United States, Delaware and/or the Cayman Islands could result in the inability of the Fund and/or its Subsidiaries to operate as described in this Prospectus and the SAI and could adversely affect the Fund. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax or withholding tax on the Cayman Subsidiary or the SPC. If Cayman Islands act changes such that the Cayman Subsidiary and/or the SPC must pay Cayman Islands taxes, Fund shareholders would likely suffer decreased investment returns.

The following table, which includes all applicable sales loads, compares the average annual total returns of the Class I Shares, Class A Shares and Class C Shares for the one-year, five-year, and since inception periods to a broad-based market index for the same periods. For Class A Shares, the table reflects the impact of the maximum sales charge of 5.75%. For this reason, returns for Class A Shares will be lower than those of Class I and Class C Shares. Average annual returns for Class T Shares are not included because they had not commenced operations prior to the date of this Prospectus. The returns for Class T Shares would be substantially similar to returns for Class I Shares because the shares are invested in the same portfolio of securities, and would differ only to the extent that the classes have different expenses.

Portfolio Turnover [Text Block]

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 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. During the most recent fiscal year ended August 31, 2022, the portfolio turnover rate for the Fund was 0% of the average value of its portfolio. In accordance with industry practice, derivative instruments and instruments with a maturity of one year or less at the time of acquisition are excluded from the calculation of the portfolio turnover rate, which leads to the 0% portfolio turnover rate reported above. If those instruments were included in the calculation, the Fund would have a higher portfolio turnover rate.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets (including borrowing for investment purposes) in equity securities of small or micro-cap companies. Small or micro-cap companies are generally considered to be those whose market capitalization are, at the time the Fund makes an investment, within the range of the market capitalization of companies in the Russell Microcap Index ($2.5 million to $2.9 billion as of December 6, 2022), the Russell 2000^® Index ($8.4 million to $8.7 billion as of December 6, 2022), or the S&P SmallCap 600^® Index ($170 million to $5.7 billion as of November 30, 2022). Securities of companies whose market capitalization no longer meet this definition after purchase may continue to be held by the Fund.

The Fund utilizes a “multi-manager” approach whereby the Fund’ assets are allocated to one or more sub-advisers (“Sub-Advisers”) in percentages determined at the discretion of the Fund’s investment adviser, Altair Advisers LLC (the “Adviser”). The Adviser also monitors Sub-Adviser trading with the dual objectives of maximizing each Sub-Adviser’s investment flexibility and assuring that the Fund as a whole complies with its investment restrictions. Otherwise, each Sub-Adviser acts independently from the others and utilizes its own distinct investment style in selecting securities. However, each Sub-Adviser must operate within the constraints of the Fund’s investment objective and strategies and the particular investment restrictions applicable to that Sub-Adviser.

The Sub-Advisers will implement a number of different investment strategies and styles within the small and micro-cap universe. The Sub-Advisers will implement one or more of the following investment strategies summarized below:

●	Small or Micro-Cap Growth — A Sub-Adviser following a growth investment style is expected to invest primarily in small or micro-cap companies with consistent or accelerating growth in earnings, revenues, cash flow, and/or other financial metrics.

●	Small or Micro-Cap Value — A Sub-Adviser following a value investment style is expected to invest primarily in small or micro-cap companies that are out of favor and/or undervalued in comparison to their peers or their growth prospects.

●	Small or Micro-Cap Core — A Sub-Adviser following a core investment style is expected to invest in small or micro-cap companies that have both value characteristics and growth characteristics.

●

Tax Loss Harvesting — A Sub-Adviser following a tax loss harvesting style is expected to hold a portfolio of securities that will have a pre-tax return similar to the performance of the S&P SmallCap 600^® Index. The Sub-Adviser will seek to generate strong after tax returns by timing trades to avoid realizing capital gains and to harvest losses when possible. The Fund may use losses generated from the tax loss harvesting Sub-Adviser to offset gains from other Sub-Advisers.

The Fund’s Sub-Advisers will invest primarily in equities and equity-related instruments of small and micro-cap companies. Equities and equity-related instruments include common stocks, preferred stocks, convertible securities, sponsored and unsponsored depositary receipts, warrants and rights. The Fund may participate as a purchaser in initial public offerings of securities (“IPOs”). An IPO is a company’s first offering of stock to the public. The Fund may also invest in companies that may experience unusual and possibly unique developments, or “special situations”, which may create a special opportunity for significant returns. Special situations include: significant technological improvements or important discoveries; reorganizations, recapitalizations or mergers; favorable resolutions of litigation; new management or material changes in company policies; and actual or potential changes in control of a company. The Sub-Advisers may also invest in real estate investment trusts (“REITs”), debt securities, and foreign securities (directly and through depository receipts).

Risk Narrative [Text Block]

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.

●

Allocation Risk. The Fund’s overall risk level will depend on the market sectors in which the Sub-Advisers are invested. Although the Fund will not concentrate in any industry, because the Fund may have significant weightings in a particular company, industry or market sector, the value of Shares may be affected by events that adversely affect that company, industry or market sector and may fluctuate more than that of a less focused fund.

●

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.

●

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, 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 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 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.

●

Equity Securities Risk. The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities held by 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 downturn and when growth stocks are out of favor.

●

Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance will likely decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

●	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 do not work to achieve their desired result.

●

Market Risk. The net asset value (“NAV”) of the Fund will change with changes in the market value of its portfolio positions. The value of the Fund’s portfolio positions 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. Investors may lose money.

●

Multi-Manager Dependence Risk. The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Sub-Advisers and to allocate assets to those Sub-Advisers and on each Sub-Adviser’s ability to execute the relevant strategy and select investments for the Fund. The Sub-Advisers’ investment styles may not always be complementary, which could affect the performance of the Fund and lead to higher transaction expenses as compared to a fund using a single investment management style.

●

Portfolio Turnover Risk. The Adviser and Sub-Advisers 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.

●

REIT Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self liquidation, interest rate risks (especially mortgage REITS) and liquidity risks. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the 1940 Act. The Fund will indirectly bear its proportionate share of any expenses, including management fees, paid by an externally managed REIT in which it invests.

●

Small and Micro-Cap Risk. The securities of small and micro-cap companies may be more volatile in price, have wider spreads between their bid and ask prices, and have significantly lower trading volumes than the securities of larger capitalization companies. As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Fund may need a considerable amount of time to purchase or sell its positions in these securities. Some small and micro-cap companies are followed by few, if any, securities analysts, and there tends to be less publicly available information about such companies. The small and micro-cap securities in which the Fund invests may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. They generally have even more limited trading volumes and are subject to even more abrupt or erratic market price movements than are mid and large cap securities, and the Fund may be able to deal with only a few market-makers when purchasing and selling securities. Small and micro-cap companies also may have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Smaller company stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks. Moreover, the lack of an efficient market for the securities may make them difficult to value.

●

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

●

Sub-Adviser and Strategy Concentration Risk. Because the Adviser will not be subject to fixed limitations upon the amount of Fund assets that may be invested with a single Sub-Adviser or in a single investment strategy, the Fund may be more heavily exposed to the investment judgments of one or more Sub-Advisers or the possible increased risk of investing in a limited number of investment strategies.

●

Tax-Managed Investment Risk. A portion of the Fund's portfolio will be managed using a tax-managed approach. Market conditions may limit the Fund's ability to implement its tax-managed approach. For example, market conditions may limit the Fund's ability to generate tax losses or to generate qualified dividend income, which is generally taxed to noncorporate shareholders at favorable rates. The Fund's ability to utilize various tax-management techniques may be curtailed or eliminated in the future by legislation or regulation. Although the Fund expects that a smaller portion of its total return will consist of taxable distributions to shareholders as compared to non-tax managed funds, there can be no assurance about the size of taxable distributions to shareholders. The performance of the Fund may deviate from that of non-tax managed funds and may not provide as high of a return before or after consideration of federal income tax consequences as non-tax managed funds.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

●

Value Stock Risk. Value investing involves buying stocks that are out of favor and/or undervalued in comparison to their peers or their prospects for growth. Typically, their valuation levels are less than those of growth stocks. 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 downturn and when value stocks are out of favor.

Portfolio Turnover [Text Block]

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. For the most recent fiscal year, the Fund’s portfolio turnover rate was 52% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 the Fund for the time periods indicated and then hold or 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing, under normal circumstances, primarily in securities of companies located outside the United States, including emerging market countries. The Fund determines where a company is located, and thus, whether a company is considered to be located outside the United States by considering whether: (i) it is organized under the laws of or maintains its principal office in a country located outside the United States; (ii) its securities are principally traded on trading markets in countries located outside the United States; (iii) it derives at least 50% of its total revenue or profits from either goods produced or services performed or sales made in countries located outside the United States; or (iv) it has at least 50% of its assets in countries located outside the United States. The Fund may invest in companies of any size capitalization.

The Fund utilizes a “multi-manager” approach whereby the Fund’s assets are allocated to one or more sub-advisers (“Sub-Advisers”) in percentages determined at the discretion of the Fund’s investment adviser, Altair Advisers LLC (the “Adviser”). The Adviser also monitors Sub-Adviser trading with the dual objectives of maximizing each Sub-Adviser’s investment flexibility and assuring that the Fund as a whole complies with its investment restrictions. Otherwise, each Sub-Adviser acts independently from the others and utilizes its own distinct investment style in selecting securities. However, each Sub-Adviser must operate within the constraints of the Fund’s investment objective and strategies and the particular investment restrictions applicable to that Sub-Adviser.

The Sub-Advisers will implement a number of different investment strategies and styles within the international universe. The Sub-Advisers will implement one or more of the following investment strategies summarized below:

●

Developed Market — A Sub-Adviser following the developed market style is expected to invest primarily in companies located in those countries included in the MSCI EAFE Index. As of October 31, 2022, the following countries were included in the MSCI EAFE Index: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. When investing in developed international markets, a Sub-Adviser may follow either a growth or a value investment style. A Sub-Adviser following a growth investment style would invest primarily in companies with consistent or accelerating growth in earnings, revenues, cash flow, and/or other financial metrics. A Sub-Adviser following a value investment style would invest primarily in companies that are out of favor and/or undervalued in comparison to their peers or their growth prospects.

●

Emerging Market — A Sub-Adviser following the emerging market style is expected to invest primarily in companies located in those countries included in the MSCI Emerging Markets Index. As of October 31, 2022, the following countries were included in the MSCI Emerging Markets Index: Brazil, Chile, China, Colombia, Czech Republic, Egypt, Greece, Hungary, India, Indonesia, Korea, Kuwait, Malaysia, Mexico, Peru, Philippines, Poland, Qatar, Saudi Arabia, South Africa, Taiwan, Thailand, Turkey and United Arab Emirates.

●

Tax Loss Harvesting — A Sub-Adviser following a tax loss harvesting style is expected to hold a portfolio of securities that will have a pre-tax return similar to the performance of the MSCI EAFE Index. The Sub-Adviser will seek to generate strong after tax returns by timing trades to avoid realizing capital gains and to harvest losses when possible. The Fund may use losses generated from the tax loss harvesting Sub-Adviser to offset gains from other Sub-Advisers.

The Fund’s Sub-Advisers will invest primarily in equity securities, including common stocks, preferred stocks, convertible securities, sponsored and unsponsored depositary receipts, warrants and rights. In addition to purchasing equity securities on exchanges where the companies are located, the Fund may purchase equity securities on exchanges other than where their companies are domiciled (often traded as dual listed securities) or in the form of Depositary Receipts, which include American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) or similar securities. The Fund may also invest in other investment companies, including exchange-traded funds (“ETFs”). Investments in ETFs based on foreign market indices are considered investments outside the U.S. The Fund may enter into currency contracts (such as spot, forward and futures) to hedge foreign currency exposure.

The Fund may invest a portion of its assets in fixed income securities, including securities issued by corporate and governmental issuers. The principal debt investments of the Fund will be fixed and floating rate securities with no reset terms.

The Fund may also invest in companies that may experience unusual and possibly unique developments, or “special situations”, which may create a special opportunity for significant returns. Special situations include: significant technological improvements or important discoveries; reorganizations, recapitalizations or mergers; favorable resolutions of litigation; new management or material changes in company policies; and actual or potential changes in control of a company.

Risk Narrative [Text Block]

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.

●

Allocation Risk. The Fund’s overall risk level will depend on the market sectors in which the Sub-Advisers are invested. Although the Fund will not concentrate in any industry, because the Fund may have significant weightings in a particular company, industry or market sector, the value of Shares may be affected by events that adversely affect that company, industry or market sector and may fluctuate more than that of a less focused fund.

●

American Depositary Receipts (“ADRs”) and Global Depository Receipts (“GDRs”) Risk. ADRs and GDRs may be subject to some of the same risks as direct investment in foreign companies, which includes international trade, currency, political, regulatory and diplomatic risks. In a sponsored ADR arrangement, the foreign issuer assumes the obligation to pay some or all of the depositary’s transaction fees. Under an unsponsored ADR arrangement, the foreign issuer assumes no obligations and the depositary’s transaction fees are paid directly by the ADR holders. Because unsponsored ADR arrangements are organized independently and without the cooperation of the issuer of the underlying securities, available information concerning the foreign issuer may not be as current as for sponsored ADRs and voting rights with respect to the deposited securities are not passed through. GDRs can involve currency risk since, unlike ADRs, they may not be U.S. dollar-denominated.

●

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.

●

Credit Risk. The value of your investment in the Fund may change in response to changes in the credit ratings of the Fund’s portfolio securities. Generally, investment risk and price volatility increase as a security’s credit rating declines. The financial condition of an issuer of a fixed income security held by the Fund may cause it to default or become unable to pay interest or principal due on the security. In addition, the Fund may incur expenses in an effort to protect the Fund’s interests or enforce its rights against an issuer, guarantor or counterparty or may be hindered or delayed in exercising these rights.

●

Currency and Exchange Risk. Investments in currencies, currency futures contracts, forward currency exchange contracts or similar instruments, as well as securities that are denominated in foreign currency, are subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Currency rates in foreign countries may fluctuate significantly over short periods of time for any number of reasons, including changes in interest rates, rates of inflation, governmental surpluses or deficits, intervention (or the failure to intervene) by U.S. or foreign governments, actions of central banks or supranational entities and the imposition of currency controls or other political developments in the U.S. or abroad. In addition, the Fund may engage in currency hedging transactions. Currency hedging transactions are subject to the risk that a result opposite expectations occurs (an expected decline turns into a rise and conversely) resulting in a loss to the Fund.

●

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, 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 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 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.

●

Emerging Markets Risk. The Fund will invest in emerging markets, which may carry more risk than investing in developed foreign markets. Risks associated with investing in emerging markets include limited information about companies in these countries, greater political and economic uncertainties compared to developed foreign markets, underdeveloped securities markets and legal systems, potentially high inflation rates, and the influence of foreign governments over the private sector. Further, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

●

Equity Securities Risk. The Fund is designed for investors who can accept the risks of investing in a portfolio with significant holdings of equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities held by the Fund.

●

ETF Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

Fixed Income Securities Risk. The Fund may invest in fixed income securities and is therefore subject to the risk that the prices of, and the income generated by, fixed income securities held by the Fund may decline significantly and/or rapidly in response to adverse issuer, geopolitical, regulatory, general economic and market conditions, or other developments, such as regional or global economic instability (including terrorism and related geopolitical risks), interest rate fluctuations, and those events directly involving the issuers that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment.

●

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. The Fund will invest in foreign securities and is subject to risks associated with foreign markets, such as adverse political, social and economic developments, accounting standards or governmental supervision that is not consistent with that to which U.S. companies are subject, limited information about foreign companies, less liquidity in foreign markets and less protection to the shareholders in foreign markets.

●

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 downturn and when growth stocks are out of favor.

●

Illiquid Securities Risk. Investing in illiquid securities is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such 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 a Sub-Adviser. Securities with longer maturities tend to be more sensitive to changes in interest rates, causing them to be more volatile than securities with shorter maturities. Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities. 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. 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.

●

Investments in Other Investment Companies Risk. Shareholders of the Fund will indirectly be subject to the fees and expenses of the other investment companies in which the Fund invests and these fees and expenses are in addition to the fees and expenses that Fund shareholders directly bear in connection with the Fund’s own operations. In addition, shareholders will be exposed to the investment risks associated with investments in the other investment companies. The SEC has adopted revisions to the rules permitting funds to invest in other investment companies. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

●

Large Capitalization Risk. Securities of companies with certain market capitalizations may perform differently from the equities markets generally. At times, large-cap companies may underperform as compared to small- or mid-capitalization companies, and vice versa. Larger, more established companies may be unable to respond to new competitive challenges such as changes in consumer tastes or innovative smaller competitors.

●	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 do 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. 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. Investors may lose money.

●

Mid-Capitalization Risk. Securities of mid-capitalization companies are often more volatile and less liquid than investments in larger companies. The frequency and volume of trading in securities of mid-capitalization companies may be substantially less than is typical of larger companies. As a result, the securities of mid-capitalization companies may be subject to greater and more abrupt price fluctuations. In addition, mid-capitalization companies may lack the management experience, financial resources and product diversification of larger companies, making them more susceptible to market pressures and business failure.

●

Multi-Manager Dependence Risk. The success of the Fund’s investment strategy depends both on the Adviser’s ability to select Sub-Advisers and to allocate assets to those Sub-Advisers and on each Sub-Adviser’s ability to execute the relevant strategy and select investments for the Fund. The Sub-Advisers’ investment styles may not always be complementary, which could affect the performance of the Fund and lead to higher transaction expenses as compared to a fund using a single investment management style.

●

Prepayment Risk. Issuers may experience an acceleration in prepayments of mortgage loans or other receivables backing the issuers’ fixed income securities when interest rates decline, which can shorten the maturity of the security, force the Fund to invest in securities with lower interest rates, and reduce the Fund’s return. Issuers may decrease prepayments of principal when interest rates increase, extending the maturity of a fixed income security and causing the value of the security to decline.

●

Small and Micro-Capitalization Risk. The securities of small and micro-cap companies may be more volatile in price, have wider spreads between their bid and ask prices, and have significantly lower trading volumes than the securities of larger capitalization companies. As a result, the purchase or sale of more than a limited number of shares of the securities of a smaller company may affect its market price. The Fund may need a considerable amount of time to purchase or sell its positions in these securities. Some small and micro-cap companies are followed by few, if any, securities analysts, and there tends to be less publicly available information about such companies. The small and micro-cap securities in which the Fund invests may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. They generally have even more limited trading volumes and are subject to even more abrupt or erratic market price movements than are mid and large cap securities, and the Fund may be able to deal with only a few market-makers when purchasing and selling securities. Small and micro-cap companies also may have limited markets, financial resources or product lines, may lack management depth, and may be more vulnerable to adverse business or market developments. Smaller company stocks may fall out of favor relative to mid or large cap stocks, which may cause the Fund to underperform other equity funds that focus on mid or large cap stocks. Moreover, the lack of an efficient market for the securities may make them difficult to value.

●

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

●

Sub-Adviser and Strategy Concentration Risk. Because the Adviser will not be subject to fixed limitations upon the amount of Fund assets that may be invested with a single Sub-Adviser or in a single investment strategy, the Fund may be more heavily exposed to the investment judgments of one or more Sub-Advisers or the possible increased risk of investing in a limited number of investment strategies.

●

Tax-Managed Investment Risk. A portion of the Fund's portfolio will be managed using a tax-managed approach. Market conditions may limit the Fund's ability to implement its tax-managed approach. For example, market conditions may limit the Fund's ability to generate tax losses or to generate qualified dividend income, which is generally taxed to noncorporate shareholders at favorable rates. The Fund's ability to utilize various tax-management techniques may be curtailed or eliminated in the future by legislation or regulation. Although the Fund expects that a smaller portion of its total return will consist of taxable distributions to shareholders as compared to non-tax managed funds, there can be no assurance about the size of taxable distributions to shareholders. The performance of the Fund may deviate from that of non-tax managed funds and may not provide as high of a return before or after consideration of federal income tax consequences as non-tax managed funds.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

●

Value Stock Risk. Value investing involves buying stocks that are out of favor and/or undervalued in comparison to their peers or their prospects for growth. Typically, their valuation levels are less than those of growth stocks. 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 downturn and when value stocks are out of favor.

Summary of Principal Investment Strategies

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity securities of U.S. companies that, at the time of purchase, have a market capitalization that is within the range of the market capitalization of issuers in the Russell 2000® Value Index.

Risk Narrative [Text Block]

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.

●

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.

●

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 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 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 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.

●

Equity Securities Risk. The Fund may invest in, or have exposure to, equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.

●

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.

●

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 net asset value (“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 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.

●

Management Risk. The Fund is subject to the risk of poor investment selection. In other words, the individual investments of 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. 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. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

●

New Fund Risk. The Fund is a recently organized, diversified management investment company with a limited operating history. 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 the Company may determine to liquidate the Fund.

●

Non-Diversification Risk. The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

●

OTC Risk. Securities traded on OTC markets are not listed and traded on an organized exchange such as the New York Stock Exchange (“NYSE”). Generally, the volume of trading in an unlisted or OTC common stock is less than the volume of trading in an exchange-listed stock. As a result, the market liquidity of some stocks in which the Fund invests may not be as great as that of exchange-listed stocks and, if the Fund were to dispose of such stocks, the Fund may have to offer the shares at a discount from recent prices or sell the shares in small lots over an extended period of time. In addition, penny stocks and pink sheet stocks can be classified as OTC stocks.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended.

●

Rights and Warrants Risk. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right’s or warrant’s expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or 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.

●

Small-Cap Companies Risk. The stocks of smaller companies may be subject to more abrupt, erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources or may be dependent on a small or inexperienced management group, and their securities may trade less frequently and in lower volume than securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

●

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

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 $100,000 in the Fund for the time periods indicated and that you hold or sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the operating expenses of the Fund remain the same (taking into account the contractual expense limitation until its expiration). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity securities of U.S. companies that, at the time of purchase, have a market capitalization that is within the range of the market capitalization of issuers in the Russell 2000^® Value Index. As of November 30, 2022, the median market capitalization of the companies in the Russell 2000^® Value Index is $856 million and the largest stock is $7.3 billion. The Fund may invest in depositary receipts and equity securities of foreign companies. Although the Fund invests primarily in common stocks, the Fund may invest in all types of equity and equity-related securities, including (without limitation):

●

Securities convertible into common stocks.

●

Shares of real estate investment trusts (“REITs”).

●

Warrants and rights to purchase common stocks.

●

Preferred stocks.

●

Exchange-traded limited partnerships.

Special Situations: The Fund may invest in companies that may experience unusual and possibly unique developments which may create a special opportunity for significant returns. Special situations include: significant technological improvements or important discoveries; reorganizations, recapitalizations or mergers; favorable resolutions of litigation; new management or material changes in company policies; and actual or potential changes in control of a company.

Strategies: The Adviser uses a value approach to select the Fund’s investments. Using this investment style, the Adviser seeks securities selling at substantial discounts to their underlying values and then holds these securities until the market values reflect what the Adviser believes to be their intrinsic values. The Adviser employs a bottom-up strategy, focusing on undervalued industries that the Adviser believes are experiencing positive change. The Adviser then uses both qualitative and quantitative methods to assess a security’s potential value. The portfolio managers managing the Fund meet with a multitude of companies annually to identify companies with increasing returns on capital in their core businesses which are selling at attractive valuations.

Factors the Adviser looks for in selecting investments include (without limitation):

●

Increasing returns on invested capital.

●

Companies who have demonstrated an ability to generate high return on invested capital (ROIC).

●

Companies which provide solid cash flows with appropriate capital.

●

Potential catalysts such as new products, cyclical upturns and changes in management.

●

Low market valuations relative to earnings forecast, book value, cash flow and sales.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

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.

●

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 net asset value (“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 NAV.

●

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. 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. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

●

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies.

In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

●

Rights and Warrants Risk. The purchase of rights or warrants involves the risk that the Fund could lose the purchase value of a right or warrant if the right to subscribe to additional shares is not executed prior to the right’s or warrant’s expiration. Also, the purchase of rights and/or warrants involves the risk that the effective price paid for the right and/or 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.

●

Small-Cap Companies Risk. The stocks of smaller companies may be subject to more abrupt, erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent on a small or inexperienced management group, and their securities may trade less frequently and in lower volume than securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

●

Special Situations Risk. The Fund will seek to benefit from “special situations,” such as mergers, reorganizations, or other unusual events expected to affect a particular issuer. There is a risk that the “special situation” might not occur or involve longer time frames than originally expected, which could have a negative impact on the price of the issuer’s securities and fail to produce gains or produce a loss for the Fund.

Portfolio Turnover [Text Block]

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. During the period from the Fund’s commencement of operations on December 29, 2021 to the fiscal period ended August 31, 2022, the portfolio turnover rate for the Fund was 55% of the average value of its portfolio.

Summary of Principal Investment Strategies

Strategy Portfolio Concentration [Text]

rr_StrategyPortfolioConcentration

The Fund pursues its objective by investing, under normal circumstances, in a diversified portfolio of equity and equity-related securities issued by U.S. and non-U.S. companies of any capitalization size.

Risk Narrative [Text Block]

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.

●

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 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 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 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.

●

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and 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 securities of issuers in 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 of an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

●

Exchange-Traded Fund Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses,

including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

Equity Securities Risk. The Fund may invest in, or have exposure to, equity securities. Equity securities tend to be more volatile than other investment choices, such as debt and money market instruments. The value of your investment may decrease in response to overall stock market movements or the value of individual securities.

●

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. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored depositary receipts may provide less information to receipt holders. Participatory notes (“P-notes”) are derivative instruments used by investors to take positions in certain foreign securities. P-notes present similar risks to investing directly in such securities and also expose investors to counterparty risk. 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 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.

●

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares

may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

●

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 the risk of poor investment selection. In other words, the individual investments of 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. 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. Investors may lose money. Although the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

●

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

●

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.

●

New Fund Risk. The Fund is a recently organized, diversified management investment company with a limited operating history. 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 the Company may determine to liquidate the Fund.

●

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The value of options can be highly volatile, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the Investment Company Act of 1940, as amended.

●

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

●

Small-Cap Companies Risk. The stocks of smaller companies may be subject to more abrupt, erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent on a small or inexperienced management group, and their securities may trade less frequently and in lower volume than securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

●

Sustainable Investment Risk. The sustainability criterion required for Fund investment may cause the Fund to not invest in certain industries or issuers. As a result, the Fund may be overweight or underweight in certain industries or issuers relative to its benchmark index, which may cause the Fund’s performance to be more or less sensitive to developments affecting those industries or issuers. Sustainability information provided by issuers, upon which the portfolio managers may rely, continues to develop, and may be incomplete, inaccurate, use different methodologies, or be applied differently across companies and industries. Further, the regulatory landscape for sustainable investing in the United States is still developing and future rules and regulations may require the Fund to modify or alter its investment process. Similarly, government policies incentivizing issuers to engage in sustainable practices may fall out of favor, which could potentially limit the Fund’s investment universe. There is also a risk that the companies identified through the investment process may fail to adhere to sustainable business practices, which may result in the Fund selling a security when it might otherwise be disadvantageous to do so. There is no guarantee that sustainable investments will outperform the broader market on either an absolute or relative basis.

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 $100,000 in the Fund for the time periods indicated and that you hold or sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the operating expenses of the Fund remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a hedged strategy. The Fund actively invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales (i.e., sales of securities the Fund does not own) are invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage.

The Fund invests, both long and short, in equity securities issued by large-, mid- and small (or “micro”) cap companies, as well as other instruments that are convertible into equity securities. Selling securities short is a form of leverage. Equity securities in which the Fund may invest include exchange-traded and over-the-counter common and preferred stocks, warrants, rights, convertible securities, depositary receipts and

shares, trust certificates, limited partnership interests, shares of other investment companies and real estate investment trusts (“REITs”), and equity participations. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Fund may also invest in depositary receipts and equity securities of foreign companies (denominated in either U.S. dollars or foreign currencies), put and call options, futures, indexed securities and fixed-income securities (including bonds, notes, asset-backed securities, convertible securities, Eurodollar and Yankee dollar instruments, preferred stocks and money market instruments) and high yield securities (commonly referred to as “junk bonds”). Fixed income securities in which the Fund invests include those rated between AAA and D by a nationally recognized statistical rating organization, or deemed of comparable quality by the Adviser. The Adviser may also temporarily invest uninvested cash in money market funds and similar collective investment vehicles. The Fund may also seek to increase its income by lending portfolio securities.

The Adviser determines the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the U.S. equity market by investing less than 100% of its assets in net long positions. Selection of individual securities to be held long or sold short will be based on a mix of quantitative techniques and fundamental security analysis. The Adviser selects stocks on the basis of three criteria: value, fundamental business strength and momentum. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

Although the Fund seeks to follow a hedged strategy, there can be no assurance that the Fund’s portfolio or investments will be insulated from market moves or effectively hedged against risk.

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

The principal derivative instruments in which the Fund invests are futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, the Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash and eligible U.S. dollar-denominated money market instruments and make investments inconsistent with its investment objective. The Adviser will determine when market conditions warrant temporary defensive measures.

Risk Narrative [Text Block]

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.

●

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 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 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 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.

●

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and 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.

●

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

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 currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and 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 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 Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations (of any rating, including defaulted securities and unrated securities), including bonds and debentures, issued by corporations and business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

●

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

Indexed Securities Risk. The Fund may invest in indexed securities whose value is linked to securities indices. Most such securities have values that rise and fall according to the change in one or more specified indices and may have characteristics similar to direct investments in the underlying securities. Depending on the index, such securities may have greater volatility than the market as a whole.

●

Management Risk. The Fund is subject to the risk of poor investment selection. The Adviser may be incorrect in the stocks it buys and believes to be undervalued and in stocks it sells short and believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical mutual fund with only a long portfolio.

●

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. 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. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies.

REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

●

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

●

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

●

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Expense Example Narrative [Text Block]

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 the Fund for the time periods indicated and that you hold or sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the operating expenses of the Fund remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund uses a hedged strategy. The Fund actively invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales (i.e., sales of securities the Fund does not own) are invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage.

The Fund invests, both long and short, in equity securities issued by large-, mid- and small (or “micro”)-cap companies, as well as other instruments that are convertible into equity securities. Equity securities in which the Fund may invest include exchange-traded and over-the-counter common and preferred stocks, warrants, rights, convertible securities, depositary receipts and shares, trust certificates, limited partnership interests,

shares of other investment companies and real estate investment trusts (“REITs”), and equity participations. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Fund may also invest in depository receipts and equity securities of foreign companies (denominated in either U.S. dollars or foreign currencies), put and call options, futures, indexed securities and fixed-income securities (including bonds, notes, asset-backed securities, convertible securities, Eurodollar and Yankee dollar instruments, preferred stocks and money market instruments) and high yield securities (commonly referred to as “junk bonds”). Fixed income securities in which the Fund invests include those rated between AAA and D by a nationally recognized statistical rating organization (“NRSRO”), or deemed of comparable quality by the Adviser. The Adviser may also temporarily invest uninvested cash in money market funds and similar collective investment vehicles. The Fund may also seek to increase its income by lending portfolio securities.

The Adviser determines the size of each long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Fund seeks to construct a portfolio that has less volatility than the U.S. equity market by investing less than 100% of its assets in net long positions. Selection of individual securities to be held long or sold short will be based on a mix of quantitative techniques and fundamental security analysis. The Adviser selects stocks on the basis of three criteria: value, fundamental business strength and momentum. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals such as return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

Although the Fund seeks to follow a hedged strategy, there can be no assurance that the Fund’s portfolio or investments will be insulated from market moves or effectively hedged against risk.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange-traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

The principal derivative instruments in which the Fund invests are futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, the Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash and eligible U.S. dollar-denominated money market instruments and make investments inconsistent with its investment objective. The Adviser will determine when market conditions warrant temporary defensive measures.

Risk Narrative [Text Block]

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.

●

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 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 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 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.

●

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and 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.

●

Exchange-Traded Fund Risk. Exchange-traded funds (“ETFs”) are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an Adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

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 currency exchange rate volatility, political, social or economic instability, less publicly available information, less stringent investor protections, and differences in taxation, auditing and 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 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 Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations (of any rating, including defaulted securities and unrated securities), including bonds and debentures, issued by corporations and business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

●

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. Less liquid securities that the fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

Indexed Securities Risk. The Fund may invest in indexed securities whose value is linked to securities indices. Most such securities have values that rise and fall according to the change in one or more specified indices and may have characteristics similar to direct investments in the underlying securities. Depending on the index, such securities may have greater volatility than the market as a whole.

●

Management Risk. The Fund is subject to the risk of poor investment selection. The Adviser may be incorrect in the stocks it buys and believes to be undervalued and in stocks it sells short and believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio.

●

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. 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. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the price of these stocks will not move even lower.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than

the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

●

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

●

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited.

●

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in long positions in stocks identified by the Adviser as undervalued and takes short positions in stocks that the Adviser has identified as overvalued. The cash proceeds from short sales will be invested in short-term cash instruments to produce a return on such proceeds just below the federal funds rate. Short sales are considered speculative transactions and a form of leverage. The Fund invests, both long and short, in securities issued by U.S. and non-U.S. companies of any capitalization size.

With a long position, the Fund purchases a stock outright; with a short position, the Fund sells a security that it does not own and must borrow to meet its settlement obligations. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”). The Adviser will determine the size of each

long or short position by analyzing the tradeoff between the attractiveness of each position and its impact on the risk of the overall portfolio. The Adviser examines various factors in determining the value characteristics of such issuers including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, including return on equity, earnings growth and cash flow. The Adviser selects securities for the Fund based on a continuous study of trends in industries and companies, earnings power and growth and other investment criteria.

The Fund may invest in all types of equity and equity-related securities, including without limitation exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies (including exchanged-traded funds (“ETFs”)), real estate investment trusts (“REITs”) and equity participation. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula.

The Fund defines non-U.S. companies as companies (i) that 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 that derive a significant portion of their revenue or profits from businesses, investments or sales, outside of the United States. Under normal market conditions, the Fund invests 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 principally will be invested in issuers located in countries with developed securities markets, but may also invest in issuers located in emerging markets. The Fund will allocate its assets among various regions and countries, including the United States (but in no less than three different countries).

The Fund’s portfolio is rebalanced regularly. The Adviser assesses each investment’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell an investment held long or close out a short position that the Adviser believes no longer offers an appropriate return-to-risk tradeoff.

Under normal circumstances, the Adviser expects to sell securities short so that the Fund’s portfolio is approximately 50% net long with an average of between 30% and 70% net long.

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

The Fund may participate as a purchaser in initial public offerings of securities (“IPO”). An IPO is a company’s first offering of stock to the public.

The Fund may invest from time to time a significant portion of its assets in smaller issuers which are more volatile and less liquid than investments in issuers with larger market capitalizations.

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

In general, the Fund’s investments are broadly diversified over a number of industries and, as a matter of policy, the Fund is limited to investing a maximum of 25% of its total assets in any one industry. The Fund is non-diversified, and may invest in fewer securities at any one time than a diversified fund.

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by U.S. and foreign corporations and other business organizations (e.g., trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Non-investment grade fixed income securities (commonly known as “junk bonds”) are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded.

The Fund may (but is not required to) invest in derivatives, including put and call options, futures, forward contracts and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and non-hedging purposes.

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, the Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash and eligible U.S. dollar-denominated money market instruments and make investments inconsistent with its investment objective. The Adviser will determine when market conditions warrant temporary defensive measures.

Risk Narrative [Text Block]

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.

●

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 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 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 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.

●

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and 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 securities of issuers in 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. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

●

Exchange-Traded Fund Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

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. The Fund may invest in securities of foreign issuers either directly or through depositary receipts. Depositary receipts may be available through “sponsored” or “unsponsored” facilities. Holders of unsponsored depositary receipts generally bear all of the costs of the unsponsored facility. The depository of an unsponsored facility is frequently under no obligation to distribute shareholder communications received from the issuer of the deposited security or to pass through, to the holders of the receipts, voting rights with respect to the deposited securities. The depository of unsponsored

depositary receipts may provide less information to receipt holders. Participatory notes (“P-notes”) are derivative instruments used by investors to take positions in certain foreign securities. P-notes present similar risks to investing directly in such securities and also expose investors to counterparty risk. 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 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 Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also, changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

●

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

●

Management Risk. The Fund is subject to the risk of poor investment selection. In other words, the Adviser may not be successful in its strategy of taking long positions in stocks the manager believes to be undervalued and short positions in stocks the manager believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical stock mutual fund with only a long portfolio may make.

●

Market Risk. The NAV of the Fund will change with changes in the market value of its portfolio positions. 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. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

●

Non-Diversification Risk. The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

●

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The value of options can be highly volatile, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

●

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will 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. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

●

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

●

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited. The use of short sales may cause the Fund to have higher expenses than those of other equity mutual funds because of higher transaction costs, premiums, interest or dividends payable to the lender.

●

Small-Cap Companies Risk. The small capitalization equity securities in which the Fund may invest may be traded only in the over-the-counter market or on a regional securities exchange, may be listed only in the quotation service commonly known as the “pink sheets,” and may not be traded every day or in the volume typical of trading on a national securities exchange. These securities may also be subject to wide fluctuations in market value. The trading market for any given small capitalization equity security may be sufficiently small as to make it difficult for the Fund to dispose of a substantial block of

such securities. The sale by the Fund of portfolio securities to meet redemptions may require the Fund to sell its small capitalization securities at a discount from market prices or during periods when, in the Adviser’s judgment, such sale is not desirable. Moreover, the lack of an efficient market for these securities may make them difficult to value.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

The Example assumes that you invest $100,000 in the Fund for the time periods indicated and that you hold or sell all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the operating expenses of the Fund remain the same (taking into account the contractual expense limitation until its expiration).

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund will pursue its objective by investing, under normal circumstances, at least 80% of its net assets (including borrowings for investment purposes) in equity and equity-related securities. The Fund will invest in a non-diversified, multi-strategy long-short portfolio of equity securities and financial investments with equity like characteristics designed to provide exposure to emerging markets. Securities are selected by the Adviser using its “three circles” approach which combines a quantitative screening with a fundamental bottom up selection process. This investment strategy is grounded in the following principles: (1) low valuation stocks outperform high valuation stocks; (2) companies with strong fundamentals, e.g., high and sustainable returns on invested capital, outperform companies with weak fundamentals; and (3) stocks with positive business momentum, e.g., rising earnings estimates, outperform stocks with negative business momentum. With a long position, the Fund purchases a stock outright; with a short position, the Fund sells a security that it does not own and must borrow to meet its settlement obligations. The Adviser examines various factors in determining the value characteristics of issuers, including price-to-book value ratios and price-to-earnings ratios. These value characteristics are examined in the context of the issuer’s operating and financial fundamentals, such as return-on-equity and earnings growth and cash flow.

The Fund intends, under normal circumstances, to invest at least 80% of its net assets (including borrowings for investment purposes) in the securities of emerging market issuers, related derivative instruments and other investments that are tied economically to emerging market countries. The Adviser considers an emerging market country to include any country that is: 1) generally recognized to be an emerging market country by the international financial community, including the World Bank; 2) classified by the United Nations as a developing country; or 3) included in the MSCI Emerging Markets Index. Due to the unique relationship between China and its separately administered regions, the Adviser includes Hong Kong and Macau as emerging markets, independent of above definitions 1 through 3. The Adviser determines that an investment is tied economically to an emerging market if such investment satisfies one or more of the following conditions: 1) the issuer’s primary trading market is in an emerging market; 2) the issuer is organized under the laws of, derives at least 50% of its revenue from, or has at least 50% of its assets in emerging markets; 3) the investment is included in an index representative of emerging markets; and 4) the investment is exposed to the economic risks and returns of emerging markets.

In managing the Fund’s portfolio, the Adviser will seek to identify mispriced publicly traded equity securities of emerging market companies including shorting securities that the Adviser believes will underperform and purchasing securities that the Adviser believes will outperform.

The long portion of the portfolio will emphasize low valuation, positive business momentum and high quality securities. The short portfolio will emphasize securities with high valuation risk, high balance sheet risk and signs of slowing sales and earnings momentum.

The Fund’s portfolio is rebalanced regularly to maintain the optimal risk/return trade-off. The Adviser assesses each stock’s changing characteristics relative to its contribution to portfolio risk. The Adviser will sell a stock held long or close out a short position in a stock that the Adviser believes no longer offers an appropriate return-to-risk tradeoff.

The equity securities in which the Fund will invest include equity securities issued by large-, mid- and small- or micro-cap companies, as well as exchange-traded and over-the-counter common and preferred stocks, warrants, options, rights, convertible securities, sponsored and unsponsored depositary receipts and shares, trust certificates, limited partnership interests, shares of other investment companies (including exchanged-

traded funds (“ETFs”)), real estate investment trusts (“REITs”) and equity participations. An equity participation is a type of loan that gives the lender a portion of equity ownership in a property, in addition to principal and interest payments. A convertible security is a bond, debenture, note, preferred stock or other security that may be converted into or exchanged for a prescribed amount of common stock of the same or a different issuer within a particular period of time at a specified price or formula. The Fund may invest in securities of companies operating for three years or less (“unseasoned issuers”).

The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, used by corporations and other business organizations (e.g., trusts or limited liability companies). Such high yield debt obligations are not considered to be investment grade. Non-investment grade fixed income securities (commonly known as “junk bonds”) are rated BB or lower by S&P Global, or have a comparable rating by another nationally recognized statistical rating organization (or, if unrated are determined by the Adviser to be of comparable quality at the time of investment). The Fund may invest in securities of the lowest rating category, including securities in default. The Adviser may, but is not required to, sell a bond or note held by the Fund in the event that its credit rating is downgraded. The Fund will primarily invest in fixed income instruments, including high yield fixed income obligations, when the Fund believes that such instruments offer a better risk/reward profile than comparable equity opportunities.

Under normal circumstances, the Adviser expects that the Fund’s long positions will not exceed approximately 50% of the Fund’s net assets with a typical range of 30% to 70% net long.

The Fund’s long and short positions may involve (without limit) equity securities of non-U.S. issuers that are traded in the markets of the United States.

In addition to the short sales discussed above, the Fund may make short sales “against the box,” a transaction in which the Fund enters into a short sale of a security which the Fund owns. The proceeds of the short sale will be held by a broker until the settlement date at which time the Fund delivers the security to close the short position. The Fund receives the net proceeds from the short sale. It is currently expected that the majority of the Fund’s short sales will not be against the box.

To meet margin requirements, redemptions or pending investments, the Fund may also temporarily hold a portion of its assets in full faith and credit obligations of the United States government and in short-term notes, commercial paper or other money market instruments.

The Fund is the sole shareholder of Boston Partners Emerging Markets Long/Short Offshore Ltd., a wholly-owned subsidiary organized under the laws of the Cayman Islands (the “Subsidiary”). Generally, the Subsidiary invests primarily in futures contracts traded on Indian stock exchanges. The Fund and its Subsidiary comply with the same fundamental investment restrictions on an aggregate basis, to the extent those restrictions are applicable to the investment activities of the Subsidiary. The Fund is the sole shareholder of its Subsidiary and does not expect shares of its Subsidiary to be offered or sold to other investors. An election has been made to cause the Subsidiary to be a disregarded entity for U.S. federal income tax purposes; accordingly, the assets and income of the Subsidiary will be treated for U.S. federal income tax purposes no differently from the other assets and income of the Fund.

The Adviser will sell a stock when it no longer meets one or more investment criteria, either through obtaining target value or due to an adverse change in fundamentals or business momentum. Each holding has a target valuation established at purchase, which the Adviser constantly monitors and adjusts as appropriate.

In general, the Fund’s investments will be spread over a number of industries and, as a matter of policy, the Fund is limited to investing less than 25% of its total assets in any one industry, except that the Fund may invest in exchange traded funds to the extent permitted by the Investment Company Act of 1940, as amended (“1940 Act”), and applicable SEC orders.

The Fund may participate as a purchaser in initial public offerings of securities (“IPOs”). An IPO is a company’s first offering of stock to the public.

The Fund may invest up to 15% of its net assets in illiquid investments, including investments that are illiquid by virtue of the absence of a readily available market or legal or contractual restrictions on resale.

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

The Fund will invest in derivatives, including put and call options, futures, contracts for differences, forward contracts and swaps, in lieu of investing directly in a security, currency or instrument, for hedging and non-hedging purposes. Contracts for differences offer exposure to price changes in an underlying security without ownership of such security, typically by providing investors the ability to trade on margin. The Fund’s investments in derivative instruments may be leveraged and result in losses exceeding the amounts invested.

While the Adviser intends to fully invest the Fund’s assets at all times in accordance with the above-mentioned policies, the Fund reserves the right to hold up to 100% of its assets, as a temporary defensive measure, in cash and eligible U.S. dollar-denominated money market instruments and make investments inconsistent with its investment objective. The Adviser will determine when market conditions warrant temporary defensive measures.

Risk Narrative [Text Block]

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.

●

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 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 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 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.

●

Derivatives Risk. The Fund’s investments in derivative instruments, which include futures and options on securities, securities indices or currencies, options on these futures, forward foreign currency contracts and interest rate or currency swaps, may be leveraged and 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 securities of issuers in 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. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

●

Exchange-Traded Fund Risk. ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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 net asset value (“NAV”).

●

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 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 Yield Debt Obligations Risk. The Fund may invest up to 20% of its net assets in high yield debt obligations, such as bonds and debentures, issued by corporations and other business organizations. An issuer of debt obligations may default on its obligation to pay interest and repay principal. Also,

changes in the financial strength of an issuer or changes in the credit rating of a security may affect its value. Such high yield debt obligations are referred to as “junk bonds” and are not considered to be investment grade.

●

Illiquid Investments Risk. Investing in illiquid investments is subject to certain risks, such as limitations on resale and uncertainty in determining valuation. Limitations on resale may adversely affect the marketability of portfolio securities and the Fund might be unable to dispose of restricted or other illiquid investments promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. The Fund might, in order to dispose of restricted securities, have to register securities resulting in additional expense and delay. Adverse market conditions could impede such a public offering of such securities. Less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Federal banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund’s ability to buy or sell such securities.

●

IPO Risk. IPO risk is the risk that the market value of IPO shares will fluctuate considerably due to certain factors, such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer. The purchase of IPO shares may involve high transaction costs. IPO shares are subject to market risk and liquidity risk. When the Fund’s asset base is small, a significant portion of the Fund’s performance could be attributable to investments in IPOs, because such investments would have a magnified impact on the Fund. As the Fund’s assets grow, the effect of the Fund’s investments in IPOs on the Fund’s performance probably will decline, which could reduce the Fund’s performance. Because of the price volatility of IPO shares, the Fund may choose to hold IPO shares for a very short period of time. This may increase the turnover of the Fund’s portfolio and may lead to increased expenses to the Fund, such as commissions and transaction costs. In addition, the Adviser cannot guarantee continued access to IPOs.

●

Management Risk. The Fund is subject to the risk of poor investment selection. The Adviser may not be successful in its strategy of taking long positions in securities the Adviser believes to be undervalued and short positions in securities the Adviser believes to be overvalued. Further, since the Adviser will manage both a long and a short portfolio, there is the risk that the Adviser may make more poor investment decisions than an adviser of a typical mutual fund with only a long portfolio may make. Investments the Fund makes 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. 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. Investors may lose money. Although the long portfolio of the Fund will invest in stocks the Adviser believes to be undervalued, there is no guarantee that the prices of these stocks will not move even lower.

●

Micro-Cap Companies Risk. Micro-cap stocks may be very sensitive to changing economic conditions and market downturns because the issuers often have narrow markets for their products or services, fewer product lines, and more limited managerial and financial resources than larger issuers. The stocks of micro-cap companies may therefore be more volatile and the ability to sell them at a desirable time or price may be more limited.

●

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.

●

Non-Diversification Risk. The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

●

Options Risk. An option is a type of derivative instrument that gives the holder the right (but not the obligation) to buy (a “call”) or sell (a “put”) an asset in the near future at an agreed upon price prior to the expiration date of the option. The Fund may “cover” a call option by owning the security underlying the option or through other means. The value of options can be highly volatile, and their use can result in loss if the Adviser is incorrect in its expectation of price fluctuations. Losses incurred by the Fund in writing options can be potentially unlimited.

●

Portfolio Turnover Risk. If the Fund frequently trades its portfolio securities, the Fund will 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. The annual portfolio turnover rate for the Fund is not expected to exceed 400%; however, it may be higher if the Adviser believes it will improve the Fund’s performance.

●

REITs Risk. REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law or (ii) maintain their exemptions from registration under the 1940 Act.

●

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

●

Short Sales Risk. Short sales of securities may result in gains if a security’s price declines, but may result in losses if a security’s price rises. In a rising market, short positions may be more likely to result in losses because securities sold short may be more likely to increase in value. Short selling is speculative and also involves the risks of: increased leverage, and its accompanying potential for losses; the potential inability to reacquire a security in a timely manner, or at an acceptable price; the possibility of the lender terminating the loan at any time, forcing the Fund to close the transaction under unfavorable circumstances; and the additional costs that may be incurred. Short sales “against the box” may protect the Fund against the risk of losses in the value of a portfolio security because any decline in the value of the security should be wholly or partially offset by a corresponding gain in the short position. Any potential gains in the security, however, would be wholly or partially offset by a corresponding loss in the short position. Short sales that are not “against the box” involve a form of investment leverage, and the amount of the Fund’s loss on a short sale is potentially unlimited. The use of short sales may cause the Fund to have higher expenses than those of other equity mutual funds because of higher transaction costs, premiums, interest or dividends payable to the lender.

●

Small-Cap Companies Risk. The stocks of smaller companies may be subject to more abrupt, erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent on a small or inexperienced management group, and their securities may trade less frequently and in lower volume than securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

●

Subsidiary Risks. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those that are permitted to be held by the Fund and are subject to the same risks

that apply to similar investments if held directly by the Fund. The Subsidiary is not registered under the 1940 Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the 1940 Act. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to continue to operate as it does currently and could adversely affect the Fund.

●

Unseasoned Issuers Risk. Unseasoned issuers may not have an established financial history and may have limited product lines, markets or financial resources. Unseasoned issuers may depend on a few key personnel for management and may be susceptible to losses and risks of bankruptcy. As a result, such securities may be more volatile and difficult to sell.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

The Fund is non-diversified. Compared to other funds, the Fund may invest more of its assets in a smaller number of companies. Gains or losses on a single stock may have greater impact on the Fund.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The bar chart and table below illustrate the long-term performance of the Fund. The bar chart below shows you how the performance of the Fund’s Institutional Class has varied year by year and provides some indication of the risks of investing in the Fund. The bar chart assumes reinvestment of dividends and distributions. As with all such investments, past performance (before and after taxes) is not an indication of future results. Updated performance information is available at www.boston-partners.com or 1-888-261-4073.

The Fund commenced operations as a series of The RBB Fund, Inc. (the “Company”) on December 15, 2015, when substantially all of the assets of Boston Partners Emerging Markets Long/Short Equity (the “Prior Account”) transferred to the Fund. The Fund is managed in all material respects in a manner equivalent to the management of the Prior Account. Accordingly, the performance information shown below for periods prior to December 15, 2015 is that of the Prior Account. The Fund’s objectives, policies, guidelines and restrictions are in all material respects equivalent to the Prior Account. The Fund is managed by Joseph F. Feeney, Jr. and Paul Korngiebel, the same Prior Account portfolio managers that managed the Prior Account since its inception in 2015. The Prior Account was not registered under 1940 Act, and thus was not subject to certain investment and operational restrictions that are imposed by the 1940 Act. If the Prior Account had been registered under the 1940 Act, its performance may have been adversely affected. Accordingly, future Fund performance may be different than the Prior Account’s restated past performance. The Prior Account’s performance has been restated to reflect estimated expenses of the Fund. After-tax performance returns are not included for the Prior Account. The Prior Account was not a regulated investment company under Subchapter M of the Internal Revenue Code and therefore did not distribute current or accumulated earnings and profits and was not subject to the diversification and source of income requirements applicable to regulated investment companies.

Portfolio Turnover [Text Block]

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 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. During the fiscal year ended August 31, 2022, the portfolio turnover rate of the Fund was 0% of the average value of its portfolio. In accordance with industry practice, derivative instruments and instruments with a maturity of one year or less at the time of acquisition are excluded from the calculation of the portfolio turnover rate, which leads to the 0% portfolio turnover rate reported above. If those instruments were included in the calculation, the Fund would have a higher portfolio turnover rate.

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. During the fiscal year ended August 31, 2022, the Fund’s portfolio turnover rate was 7% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and that you hold or sell 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 and returns might be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible

into stocks, of U.S. companies, or invest substantially all of their assets in such equity securities. The Fund will diversify its investments by investing primarily in investment companies focusing on different segments of the equity markets, including large (“large-cap”), small (“small-cap”) and micro-capitalization (“micro-cap”) equity securities that the Fund’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of long-term capital appreciation. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses.

Under normal market conditions, the Adviser expects substantially all of the Fund’s net assets to be invested in the securities of investment companies that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

U.S. Large Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of large cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Large cap companies are generally considered companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

U.S. Small Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

U.S. Large Company Asset Class: The underlying investment companies generally will purchase all of the stocks that comprise the S&P 500^® Index in approximately the proportions they are represented in the S&P 500^® Index. Generally, these are the U.S. stocks with the largest market capitalizations and, as a group, they represent approximately 80% of the total market capitalization of all publicly traded U.S. stocks.

U.S. Small Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies primarily based on market capitalization. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. small cap asset class and the U.S. micro cap asset class invest.

U.S. Micro Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of micro cap companies. Micro cap companies are generally considered companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities

exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. micro cap asset class and the U.S. small cap asset class invest.

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for U.S. equity securities and indices, to adjust market exposure based on actual or expected cash inflows to or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, options and swaps to help the ETF track its underlying index.

The Fund reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Fund employs a temporary defensive measure, the Fund may not achieve its investment objective. Periodically the Adviser will review the allocations for the Fund in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Fund in the underlying investment companies without notice to shareholders.

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.

●

Stocks of large cap, small cap or micro cap companies in which the Fund’s underlying investment companies invest or in which the Fund invests directly may temporarily fall out of favor with investors or may be more volatile than the rest of the U.S. market as a whole.

●

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

●

Although the Fund will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Fund at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

●

The Fund will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Fund to at times underperform equity funds that use other investment strategies.

●

Companies in which the Fund’s underlying investment companies invest may suffer unexpected losses or lower than expected earnings or their securities may become difficult or impossible to sell at the time and for the price that the underlying investment adviser(s) would like.

●

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Fund could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

●

Because under normal circumstances the Fund invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in U.S. equity securities, the net asset value (“NAV”) of the Fund will change with changes in the share prices of the investment companies in which the Fund invests.

●

There is a risk that large, small or micro capitalization stocks may not perform as well as other asset classes or the U.S. stock market as a whole. In the past, large, small and micro capitalization stocks have gone through cycles of doing better or worse than the stock market in general.

●

There is a risk that the Fund, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

●

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount 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.

●

The performance of the Fund will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

●

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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.

●

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.

●

The SEC has adopted revisions to the rules permitting funds to invest in other investment companies to streamline and enhance the regulatory framework applicable to fund of funds arrangements. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

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. During the fiscal year ended August 31, 2022, the Fund’s portfolio turnover rate was 3% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and that you hold or sell 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 and returns might be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in fixed income securities that the Fund’s investment adviser, Matson Money, Inc. (the

“Adviser”), believes offer the prospect of providing total return, or invest substantially all of their assets in such fixed income securities. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses.

Under normal market conditions, the Adviser expects substantially all of the Fund’s net assets to be invested in the securities of investment companies that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

One-Year Fixed Income Asset Class: The underlying investment companies generally will purchase U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the U.S.; foreign government and agency obligations, bank obligations, including the obligations of U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, and obligations of supranational organizations such as the World Bank, the European Investment Bank, and the Inter-American Development Bank. Generally, obligations comprising this asset class will mature within one year from the date of settlement, but substantial investments may be made in obligations maturing within two years from the date of settlement when greater returns are available.

Two-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, and other debt obligations of domestic and foreign issuers with maturities of no more than two years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Intermediate Government Fixed Income Asset Class: The underlying investment companies generally will purchase debt obligations of the U.S. government and U.S. government agencies. Generally, investment companies in the asset class will purchase securities with maturities of between five and fifteen years, however such investment companies ordinarily will have an average weighted maturity of between three and ten years. The underlying investment companies may invest a portion of their assets in the obligations of foreign governments. Those obligations at the time of purchase must be either rated in the highest rating category of a nationally recognized statistical rating organization or, in the case of any obligation that is unrated, of comparable quality.

Five-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. Generally, obligations comprising this asset class have a weighted average maturity not exceeding five years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Short-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 1-5 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non- U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to one year and less than five years.

Intermediate-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 5-10 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non-U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to five years and less than ten years.

Inflation Protected Securities Asset Class: The underlying investment companies generally will track the investment results of the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L), which measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS’ principal payments are adjusted according to changes in the CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase.

The underlying investment companies may also use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

Certain underlying investment companies may concentrate their investments (invest more than 25% of its total assets) in obligations of U.S. and foreign banks and bank holding companies when the yield to maturity on eligible portfolio investments in banking securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange is open for trading. While the Fund will not concentrate its investments in any one industry, the Fund may be focused on banking sectors under certain circumstances.

The Fund reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Fund employs a temporary defensive measure, the Fund may not achieve its investment objective. Periodically the Adviser will review the allocations for the Fund in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Fund in the underlying investment companies without notice to shareholders.

Risk Narrative [Text Block]

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.

●

Fixed income securities in which the Fund’s underlying investment companies may invest are subject to certain risks, including: interest rate risk, reinvestment risk, prepayment and extension risk, credit/default risk, and the risks associated with investing in repurchase agreements.

●

Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes.

●

Reinvestment risk involves the risk that proceeds from matured investments may be re-invested at lower interest rates.

●

Prepayment risk involves the risk that in declining interest rates environments prepayments of principal could increase and require the Fund to reinvest proceeds of the prepayments at lower interest rates.

●

Extension risk involves the risk that prepayments of principal will decrease when interest rates rise resulting in a longer effective maturity of a security.

●

Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. Credit risk also involves the risk that the credit rating of a security may be lowered.

●

Repurchase agreement risk involves the risk that the other party to a repurchase agreement will be unable to complete the transaction and the underlying investment company in which the Fund invests may suffer a loss as a result.

●

Because the Fund owns shares of underlying investment companies that invest in foreign issuers, the Fund is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Fund’s holdings, may change on days when shareholders are not able to purchase or redeem the Fund’s shares.

●

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Fund invests are denominated will fluctuate daily. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Fund than if it had not engaged in these contracts.

●

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Fund may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Fund’s own expenses. 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.

●

Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

●

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Fund could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

●

Because under normal circumstances the Fund invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in fixed income securities, the NAV of the Fund will change with changes in the share prices of the investment companies in which the Fund invests.

●

Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed only by the credit of the issuing agency or instrumentality. Accordingly, there may be some risk of default by the issuer in such cases.

●

There is a risk that the Fund, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

●

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount 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.

●

The performance of the Fund will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

●

Banks are very sensitive to changes in money market and general economic conditions. Adverse general economic conditions can cause financial difficulties for a bank’s borrowers and the borrowers’ failure to repay their loans can adversely affect the bank’s financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

●

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.

●

The SEC has adopted revisions to the rules permitting funds to invest in other investment companies to streamline and enhance the regulatory framework applicable to fund of funds arrangements. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Fund’s investment strategies and operations.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). These costs, which are not reflected in Total Annual Portfolio Operating Expenses or in the Example, affect the Portfolio’s performance. During the fiscal year ended August 31, 2022, the Portfolio’s portfolio turnover rate was 15% of the average value of its portfolio.

Expense Example Narrative [Text Block]

rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. This Example does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Portfolio as an investment option. Had those fees and expenses been included, the costs shown below would be higher.

The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated and that you hold or sell your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Portfolio’s operating expenses remain the same. Although your actual costs and returns might be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in equity securities, such as common stocks, preferred stocks or securities convertible into stocks, of U.S. companies, or invest substantially all of their assets in such equity securities. The Portfolio will diversify its investments by investing primarily in investment companies focusing on different segments of the equity markets, including large (“large-cap”), small (“small-cap”) and micro-capitalization (“micro-cap”) equity securities that the Portfolio’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of long-term capital appreciation. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses.

Under normal market conditions, the Adviser expects substantially all of the Portfolio’s net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

U.S. Large Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of large cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Large cap companies are generally considered companies whose market capitalizations are generally in the highest 90% of total market capitalization or companies whose market capitalizations are larger than or equal to the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

U.S. Small Cap Value Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies that the underlying investment adviser(s) determine to be value stocks at the time of purchase. An issuer’s securities are considered value stocks primarily because they have a low price in relation to their book value. In assessing value, the underlying investment adviser(s) may consider additional factors such as price to cash flow or price to earnings ratios. The criteria used for assessing value are subject to change from time to time. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions.

U.S. Large Company Asset Class: The underlying investment companies generally will purchase all of the stocks that comprise the S&P 500^® Index in approximately the proportions they are represented in the S&P 500^® Index. Generally, these are the U.S. stocks with the largest market capitalizations and, as a group, they represent approximately 80% of the total market capitalization of all publicly traded U.S. stocks.

U.S. Small Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of small cap companies primarily based on market capitalization. Small cap companies are generally considered companies whose market capitalizations are generally in the lowest 10% of total market capitalization or companies whose market capitalizations are smaller than the 1,000th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. small cap asset class and the U.S. micro cap asset class invest.

U.S. Micro Cap Asset Class: The underlying investment companies generally will purchase common stocks and other equity securities of micro cap companies. Micro cap companies are generally considered companies whose market capitalizations are generally in the lowest 5% of total market capitalization or companies whose market capitalizations are smaller than the 1,500th largest U.S. company, whichever results in the higher market capitalization break. Total market capitalization is based on the market capitalization of U.S. operating companies listed on a securities exchange in the United States that is deemed appropriate by the underlying investment adviser(s). The dollar amount will change from time to time due to market conditions. There may be some overlap in the companies in which the U.S. micro cap asset class and the U.S. small cap asset class invest.

The underlying investment companies may use derivatives, such as futures contracts and options on futures contracts for U.S. equity securities and indices, to adjust market exposure based on actual or expected cash inflows to or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, options and swaps to help the ETF track its underlying index.

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Portfolio, 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 Portfolio 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 Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

●

Stocks of large cap, small cap or micro cap companies in which the Portfolio’s underlying investment companies invest or in which the Portfolio invests directly may temporarily fall out of favor with investors or may be more volatile than the rest of the U.S. market as a whole.

●

The smaller the capitalization of a company, generally the less liquid its stock and the more volatile its price. Companies with smaller market capitalizations also tend to have unproven track records and are more likely to fail than companies with larger market capitalizations.

●

Although the Portfolio will invest in other investment companies that follow a value oriented strategy, value stocks may perform differently from the market as a whole and such a strategy may cause the Portfolio at times to underperform equity funds that use other investment strategies. Value stocks can react differently to political, economic and industry developments than the market as a whole and other types of stocks, and may underperform the market for long periods of time.

●

The Portfolio will invest in underlying investment companies that purchase stocks with high relative profitability. High relative profitability stocks may perform differently from the market as a whole and an investment strategy purchasing these securities may cause the Portfolio to at times underperform equity funds that use other investment strategies.

●

Companies in which the Portfolio’s underlying investment companies invest may suffer unexpected losses or lower than expected earnings or their securities may become difficult or impossible to sell at the time and for the price that the underlying investment adviser(s) would like.

●

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

●

Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in U.S. equity securities, the net asset value (“NAV”) of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

●

There is a risk that large, small or micro capitalization stocks may not perform as well as other asset classes or the U.S. stock market as a whole. In the past, large, small and micro capitalization stocks have gone through cycles of doing better or worse than the stock market in general.

●

There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

●

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount 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.

●

The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

●

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. the Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. 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.

●

Cyber security risk is the risk of an unauthorized breach and access to Portfolio assets, Portfolio or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, 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 Portfolio investors from purchasing, redeeming or exchanging shares or receiving distributions. The Portfolio 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 Portfolio or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio or its service providers may adversely impact and cause financial losses to the Portfolio or its shareholders. Issuers of securities in which the Portfolio 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.

●

The SEC has adopted revisions to the rules permitting funds to invest in other investment companies to streamline and enhance the regulatory framework applicable to fund of funds arrangements. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Portfolio’s investment strategies and operations.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Portfolio pursues its investment objective by investing under normal circumstances at least 80% of its net assets, including any borrowings for investment purposes, in shares of registered, open-end investment companies and exchange-traded funds (“ETFs”) (collectively, “investment companies”) that have either adopted policies to invest at least 80% of their assets in fixed income securities that the Portfolio’s investment adviser, Matson Money, Inc. (the “Adviser”), believes offer the prospect of providing total return, or invest substantially all of their assets in such fixed income securities. The purchase of shares of investment companies may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses.

Under normal market conditions, the Adviser expects substantially all of the Portfolio’s net assets to be invested in the securities of investment companies, including other investment companies funded by insurance company separate accounts, that invest in the types of securities described in each asset class below, with less than 2% of the net assets invested in cash or money market instruments.

One-Year Fixed Income Asset Class: The underlying investment companies generally will purchase U.S. government obligations, U.S. government agency obligations, dollar-denominated obligations of foreign issuers issued in the U.S., securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the U.S., foreign government and agency obligations, bank obligations, including the obligations of U.S. subsidiaries and branches of foreign banks, corporate obligations, commercial paper, repurchase agreements, and obligations of supranational organizations such as the World Bank, the European Investment Bank and the Inter-American Development Bank. Generally, obligations comprising this asset class will mature within one year from the date of settlement, but substantial investments may be made in obligations maturing within two years from the date of settlement when greater returns are available.

Two-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, and other debt obligations of domestic and foreign issuers with maturities of no more than two years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Intermediate Government Fixed Income Asset Class: The underlying investment companies generally will purchase debt obligations of the U.S. government and U.S. government agencies. Generally, investment companies in the asset class will purchase securities with maturities of between five and fifteen years, however such investment companies ordinarily will have an average weighted maturity of between three and ten years. The underlying investment companies may invest a portion of their assets in the obligations of foreign governments. Those obligations at the time of purchase must be either rated in the highest rating category of a nationally recognized statistical rating organization or, in the case of any obligation that is unrated, of comparable quality.

Five-Year Global Fixed Income Asset Class: The underlying investment companies generally will purchase obligations issued or guaranteed by the U.S. and foreign governments, their agencies and instrumentalities, corporate debt obligations, bank obligations, commercial paper, repurchase agreements, obligations of other domestic and foreign issuers, securities of domestic or foreign issuers denominated in U.S. dollars but not trading in the United States, and obligations of supranational organizations. Generally, obligations comprising this asset class have a weighted average maturity not exceeding five years. In making purchase decisions, if the expected term premium is greater for longer-term securities in the eligible maturity range, the underlying investment adviser(s) will focus investment in the longer-term area, otherwise, the underlying investment companies will focus investment in the shorter-term area of the eligible maturity range. Because many of the investments of the underlying investment companies in this asset class will be denominated

in foreign currencies, the underlying investment companies may also enter into foreign currency forward contracts to attempt to protect against uncertainty in the level of future foreign currency rates, to hedge against fluctuations in currency exchange rates or to transfer balances from one currency to another.

Short-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 1-5 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non- U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to one year and less than five years.

Intermediate-Term Corporate Bond Asset Class: The underlying investment companies generally will track the investment results of the ICE BofAML 5-10 Year US Corporate Index, which measures the performance of investment-grade corporate bonds of both U.S. and non-U.S. issuers that are U.S. dollar denominated and publicly issued in the U.S. domestic market and have a remaining maturity of greater than or equal to five years and less than ten years.

Inflation Protected Securities Asset Class: The underlying investment companies generally will track the investment results of the Bloomberg U.S. Treasury Inflation Protected Securities (TIPS) Index (Series-L), which measures the performance of the inflation-protected public obligations of the U.S. Treasury, commonly known as “TIPS.” TIPS are securities issued by the U.S. Treasury that are designed to provide inflation protection to investors. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation - a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the consumer price index (“CPI”), and TIPS’ principal payments are adjusted according to changes in the CPI. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises, both the principal value and the interest payments increase.

The underlying investment companies may also use derivatives, such as futures contracts and options on futures contracts for equity securities and indices, to hedge currency exposure or to adjust market exposure based on actual or expected cash inflows or outflows from the underlying investment company. Underlying index-based ETFs may use derivatives, including futures contracts, options on futures contracts, forward currency contracts, options and swaps to help the ETF track its underlying index.

Certain underlying investment companies may concentrate their investments (invest more than 25% of its total assets) in obligations of U.S. and foreign banks and bank holding companies when the yield to maturity on eligible portfolio investments in banking securities as a group generally exceeds the yield to maturity on all other eligible portfolio investments as a group generally for a period of five consecutive days when the New York Stock Exchange (“NYSE”) is open for trading. While the Portfolio will not concentrate its investments in any one industry, the Portfolio may be focused on banking sectors under certain circumstances.

The Portfolio reserves the right to hold up to 100% of its assets as a temporary defensive measure in cash and money market instruments such as U.S. government securities, bank obligations and commercial paper. To the extent the Portfolio employs a temporary defensive measure, the Portfolio may not achieve its investment objective. Periodically the Adviser will review the allocations for the Portfolio in each underlying investment company and may add or remove underlying investment companies and/or change the investment allocation percentages of the Portfolio in the underlying investment companies without notice to shareholders or the holders of the variable annuity or variable life insurance policies.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

Risk is inherent in all investing. The value of your investment in the Portfolio, 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 Portfolio 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 Portfolio, regardless of the order in which it appears. Different risks may be more significant at different times depending on market conditions or other factors.

●

Fixed income securities in which the Portfolio’s underlying investment companies may invest are subject to certain risks, including: interest rate risk, reinvestment risk, prepayment and extension risk, credit/default risk, and the risks associated with investing in repurchase agreements.

●

Interest rate risk involves the risk that prices of fixed income securities will rise and fall in response to interest rate changes.

●

Reinvestment risk involves the risk that proceeds from matured investments may be re-invested at lower interest rates.

●

Prepayment risk involves the risk that in declining interest rates environments prepayments of principal could increase and require the Portfolio to reinvest proceeds of the prepayments at lower interest rates.

●

Extension risk involves the risk that prepayments of principal will decrease when interest rates rise resulting in a longer effective maturity of a security.

●

Credit risk is the risk that the issuer of a security may be unable to make interest payments and/or repay principal when due. Credit risk also involves the risk that the credit rating of a security may be lowered.

●

Repurchase agreement risk involves the risk that the other party to a repurchase agreement will be unable to complete the transaction and the underlying investment company in which the Portfolio invests may suffer a loss as a result.

●

Because the Portfolio owns shares of underlying investment companies that invest in foreign issuers, the Portfolio is subject to risks presented by investments in such issuers. Securities of foreign issuers may be negatively affected by political events, economic conditions, or inefficient, illiquid or unregulated markets in foreign countries. Foreign issuers may be subject to inadequate regulatory or accounting standards. In addition, foreign securities in which the underlying investment companies invest may be listed on foreign exchanges that trade on weekends or other days when the underlying investment companies do not calculate their net asset value (“NAV”). As a result, the value of the underlying investment companies’ holdings, and therefore the Portfolio’s holdings, may change on days when shareholders are not able to purchase or redeem the Portfolio’s shares.

●

Currency risk is the risk that exchange rates for currencies in which securities held by the underlying investment companies in which the Portfolio invests are denominated will fluctuate daily. Forward foreign currency exchange contracts may limit potential gains from a favorable change in value between the U.S. dollar and foreign currencies. Unanticipated changes in currency pricing may result in poorer overall performance for the Portfolio than if it had not engaged in these contracts.

●

The Adviser’s judgment about the attractiveness or potential appreciation of a particular underlying investment company security could prove to be wrong or the Portfolio could miss out on an investment opportunity because the assets necessary to take advantage of such opportunity are tied up in less advantageous investments.

●

Because under normal circumstances the Portfolio invests at least 80% of its net assets in shares of registered investment companies that emphasize investments in fixed income securities, the NAV of the Portfolio will change with changes in the share prices of the investment companies in which the Portfolio invests.

●

Not all obligations of U.S. government agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed only by the credit of the issuing agency or instrumentality. Accordingly, there may be some risk of default by the issuer in such cases.

●

There is a risk that the Portfolio, which is passively managed, may not perform as well as funds with more active methods of investment management, such as selecting securities based on economic, financial, and market analysis.

●

The derivative instruments in which the underlying investment companies may invest are subject to a number of risks including liquidity, interest rate, market, credit and management risks, and the risk of improper valuation. Changes in the value of a derivative may not correlate perfectly with the underlying asset, rate or index, and it is possible to lose more than the principal amount 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.

●

The performance of the Portfolio will depend on how successfully the investment adviser(s) to the underlying investment companies pursue their investment strategies.

●

Banks are very sensitive to changes in money market and general economic conditions. Adverse general economic conditions can cause financial difficulties for a bank’s borrowers and the borrowers’ failure to repay their loans can adversely affect the bank’s financial situation. Banks are subject to extensive regulation and decisions by regulators may limit the loans banks make and the interest rates and fees they charge, which could reduce bank profitability.

●

Inflation protected securities, such as TIPS, generally will fluctuate in response to changes in real interest rates, generally decreasing when real interest rates rise and increasing when real interest rates fall. In addition, interest payments on inflation-protected securities will generally vary up or down along with the rate of inflation. Real interest rates are generally measured as a nominal interest less an inflation rate. As such, investors should be aware that an investment in TIPS over a particular timeframe may decrease in value even in an inflationary environment. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. Because of their inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

●

ETFs are a type of investment company bought and sold on a securities exchange. An ETF typically represents a fixed portfolio of securities designed to track a particular market index. The risks of owning an ETF generally reflect the risks of owning the underlying securities that they are designed to track, although lack of liquidity in an ETF could result in its being more volatile. Some ETFs are actively-managed by an investment adviser and/or sub-advisers. Actively-managed ETFs are subject to the risk of poor investment selection. The Portfolio may incur brokerage fees in connection with its purchase of ETF shares. The purchase of shares of ETFs may result in duplication of expenses, including advisory fees, in addition to the Portfolio’s own expenses. 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.

●

Cyber security risk is the risk of an unauthorized breach and access to Portfolio assets, Portfolio or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Portfolio, 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 Portfolio investors from purchasing, redeeming or exchanging shares or receiving distributions. The Portfolio 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 Portfolio or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Portfolio or its service providers may adversely impact and cause financial losses to the Portfolio or its shareholders. Issuers of securities in which the Portfolio 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.

●

The SEC has adopted revisions to the rules permitting funds to invest in other investment companies to streamline and enhance the regulatory framework applicable to fund of funds arrangements. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022. These regulatory changes may adversely impact the Portfolio’s investment strategies and operations.

More information about the Portfolio’s investments and risks is contained under the section entitled “More About Each Portfolio’s Investments and Risks.”

Motley Fool 100 Index ETF Summary Section

Objective, Primary [Text Block]

This Example is intended to help you compare the cost of investing in the Fool 100 Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fool 100 Fund for the time periods indicated and then hold or 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 Fool 100 Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fool 100 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 Fool 100 Index. Motley Fool Asset Management, LLC (the “Adviser” or “Motley Fool”) serves as the investment adviser to the Fool 100 Fund. The Fool 100 Index was developed by The Motley Fool, LLC (“TMF”), an affiliate of the Adviser.

The Motley Fool 100 Index

The Fool 100 Index was established by TMF in 2017 and is 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.

To be eligible for inclusion in the Fool 100 Index, a company must be among the 100 largest domestic firms by market capitalization in TMF’s “recommendation universe.” That 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.

Each of the 100 largest company’s share of the Fool 100 Index (or “weighting”) is set to equal the company’s share of all Fool 100 Index companies’ aggregate market value. The Fool 100 Index is reconstituted and rebalanced quarterly. From time to time, the Fool 100 Index may include more or less than 100 companies as a result of events such as acquisitions, spin-offs and other corporate actions.

The Fool 100 Index is calculated and administered by Solactive AG (the “Index Calculation Agent”), which is not affiliated with the Fool 100 Fund, the Adviser or TMF. Additional information regarding the Fool 100 Index, including its value, is available on the websites of the Fool 100 Index at www.fool100.com and the Index Calculation Agent, at www.solactive.com.

The Fool 100 Fund’s Investment Strategy

Under normal circumstances, at least 80% of the Fool 100 Fund’s total assets (exclusive of any collateral held from securities lending) will be invested in the component securities of the Fool 100 Index. The Adviser expects that, over time, if it has sufficient assets, the correlation between the Fool 100 Fund’s performance and that of the Fool 100 Index, before fees and expenses, will be 95% or better.

The Fool 100 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 Fool 100 Index. However, the Fool 100 Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Fool 100 Index whose risk, return and other characteristics closely resemble the risk, return and other characteristics of the Fool 100 Index as a whole, when the Adviser believes it is in the best interests of the Fool 100 Fund (e.g., when replicating the Fool 100 Index involves practical difficulties or substantial costs, a Fool 100 Index constituent becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations that apply to the Fool 100 Fund but not to the Fool 100 Index).

The Fool 100 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 Fool 100 Index, but which the Adviser believes will help the Fool 100 Fund track the Fool 100 Index. For example, the Fool 100 Fund may invest in securities that are not components of the Fool 100 Index to reflect various corporate actions and other changes to the Fool 100 Index (such as reconstitutions, additions and deletions).

The Fool 100 Fund is non-diversified for the purposes of the Investment Company Act of 1940, as amended (“1940 Act”), which means that the Fool 100 Fund may invest in fewer securities at any one time than a diversified fund. To the extent the Fool 100 Index concentrates (i.e., holds more than 25% of its total assets) in the securities of a particular industry, the Fool 100 Fund will concentrate its investments to approximately the same extent as the Fool 100 Index. As of August 31, 2022, securities in the health care, information technology, communication services and consumer discretionary sectors represented a significant portion of the Fool 100 Index.

The Fool 100 Fund may also seek to increase its income by lending securities.

The Fool 100 Fund has elected to be, and 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”).

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the Fool 100 Fund’s investments may decrease, which will cause the value of the Fool 100 Fund’s Shares to decrease. As a result, you may lose money on your investment in the Fool 100 Fund, and there can be no assurance that the Fool 100 Fund will achieve its investment objective. The Fool 100 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 Fool 100 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 Fool 100 Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fool 100 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 Fool 100 Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fool 100 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 Fool 100 Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fool 100 Fund or its service providers may adversely impact and cause financial losses to the Fool 100 Fund or its shareholders. Issuers of securities in which the Fool 100 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.

●

Equity Markets Risk. The equity securities held in the Fool 100 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 Fool 100 Fund invests. Common stocks are generally exposed to greater risk than other types of securities, such as preferred stocks and debt obligations, because common stockholders generally have inferior rights to receive payment from issuers.

●	ETF Risk. The Fool 100 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Fool 100 Fund has a limited number of financial institutions that are institutional investors and may act as 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, Fool 100 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 Fool 100 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 Fool 100 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, 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 Fool 100 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.

●

Index Rankings and Methodology Risk. The Fool 100 Index is comprised of the 100 largest U.S. companies that are either active recommendations of TMF’s newsletter or are among the 150 highest rated U.S. companies in TMF’s analyst opinion database, and are weighted based on their market value relative to the total market value of other companies in the Fool 100 Index. Factors used by TMF’s analysts in their qualitative and quantitative analysis of companies included in the Fool 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 Fool 100 Fund. In addition, changes in TMF’s recommendations or rankings methodologies may have an adverse effect on the Fool 100 Fund. Factors that affect a security’s value can change over time, and these changes may not be reflected in the Fool 100 Index methodology. Moreover, the methodology and the calculation of the Fool 100 Index could be subject to errors. If the composition of the Fool 100 Index reflects such errors, the Fool 100 Fund’s portfolio can be expected to reflect the errors, too.

●	Large-Capitalization Investing Risk. Investments in 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 Fool 100 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.

●

Non-Diversification Risk. The Fool 100 Fund is non-diversified, which means that it may invest a high percentage of its assets in a limited number of securities. Since the Fool 100 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 Fool 100 Fund.

●

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

●	Portfolio Turnover Risk. In seeking to replicate the Fool 100 Index, which is adjusted and rebalanced quarterly, the Fool 100 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 Fool 100 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. 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.

●

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 Fool 100 Fund may lend portfolio securities to institutions, such as certain broker- dealers. The Fool 100 Fund may experience a loss or delay in the recovery of its securities if the borrowing institution

breaches its agreement with the Fund.

●

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

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

The Fool 100 Fund is non-diversified, which means that it may invest a high percentage of its assets in a limited number of securities. Since the Fool 100 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 Fool 100 Fund.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Global Opportunities Fund is an actively-managed exchange-traded fund (“ETF”), and pursues its investment objective by using a quality growth investing style. The Global Opportunities Fund invests in a focused portfolio of the common stocks of high-quality U.S. companies and the common stocks and depositary receipts (including unsponsored depositary receipts) of high-quality companies that are organized under the laws of other countries around the world.

The Global Opportunities Fund will invest, under normal circumstances, in at least three different countries, and will invest at least 40% of its assets outside of the United States, or, if the conditions are not favorable, will invest at least 30% of its assets outside the United States. The Global Opportunities Fund seeks to stay fully invested and does not attempt to time the market. Although the Global Opportunities Fund does not have market capitalization constraints for its investments, it is expected that investments in the securities of U.S. companies having smaller and middle market capitalizations, which Motley Fool Asset Management, LLC (the “Adviser”) considers to be companies with market capitalizations less than $10 billion, and the securities in foreign companies, including companies organized under the laws of emerging market countries, will be important components of the Global Opportunities Fund’s investment program. As a result, the Global Opportunities Fund has the freedom to go anywhere to make investments for its shareholders.

In identifying investments for the Global Opportunities Fund, the Adviser looks for securities of companies that have high-quality businesses with strong market positions, manageable leverage, robust streams of free cash flow, and trade at attractive prices. In managing the Global Opportunities Fund’s investment portfolio, the Adviser regularly reviews and adjusts the Global Opportunities Fund’s allocations to particular markets and sectors to maintain a diversified mix of investments that the Adviser believes offer the best overall potential for long-term growth of capital. The Global Opportunities Fund will sell securities in which it has invested based upon the Adviser’s analysis of fundamental investment criteria, including its assessment of the current value of a security relative to the security’s current market price, business fundamentals relating to the issuer, and developments affecting the issuer’s business prospects and risks.

The Global Opportunities Fund prefers to invest in high-quality businesses when possible. To identify these high quality businesses, the Adviser engages in research to evaluate each company under consideration using four criteria: management, culture, and incentives; the economics of the business; competitive advantage; and trajectory. The Adviser’s approach employs a long-term mindset and a balance of qualitative and quantitative factors.

Management, Culture, and Incentives.

The Adviser believes that management is a key element to long-term success at most businesses. Among the factors the Adviser considers are: manager and board of director fit, the clarity of vision and strategies, main-line culture and turnover, ownership in the business, the sensibility of incentives, capital allocation choices and results, external transparency and candor, and overall treatment of stakeholders.

Economics of the Business.

The Adviser believes that the economic performance of a business is a signal for quality. The Adviser’s process looks at the company’s long-term return on capital, the scalability of its business model, relative and absolute margins, business and product cyclicality, and other key performance indicators to gain insight into its potential for future performance.

Competitive Advantage.

The Adviser seeks companies that offer certain characteristics that allow them to generate and sustain outsized returns on capital on an absolute basis as well as in comparison to their peers. Competitive advantages may include pricing power, geographic barriers to entry, network effects, regulatory barriers to entry, and superior brands, among others. The Adviser also assesses the strength of the supporting capabilities each company possesses that reinforce these advantages to result in unique positioning.

Trajectory.

Companies often display superior economics over the short term due to favorable product cycles, customer preference, temporary or tactical advantages or other reasons. As the Adviser’s desire is to own companies in the Global Opportunities Fund that can be kept in the portfolio for many years, a core part of the Adviser’s process is to consider what the company might look like over a period of ten or more years. The Adviser considers whether the company seems likely to grow, to increase profitability through additional products or other offerings, and if it has optionality and the financial capacity that may make it a larger, stronger business in the future than it might be today.

The Global Opportunities Fund’s investment portfolio is focused, generally composed of between 30 and 50 investment positions, with the 10 largest positions representing not more than 60% of the Global Opportunities Fund’s net assets. To limit the risks associated with highly concentrated holdings, the Global Opportunities Fund does not invest more than 5% of its net assets in any one class of the securities of any one issuer at the time of purchase. If a portfolio holding grows to be greater than 5% of the Global Opportunities Fund’s net assets the Adviser may not add additional capital to the position. However, the Adviser may maintain an allocation above 5% indefinitely, provided it continues to meet the Adviser’s investment criteria.

While investing in a particular sector is not a principal investment strategy of the Global Opportunities 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. Currently, the Global Opportunities Fund is significantly invested in the industrials sector, communication services sector, financials sector, consumer discretionary sector, and information technology sector, which means it will be more affected by the performance of such sectors than a fund that is not so significantly invested. The Global Opportunities Fund may also seek to increase its income by lending securities.

The Global Opportunities Fund has elected to be, and 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”).

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the Global Opportunities Fund’s investments may decrease, which will cause the value of the Global Opportunities Fund’s Shares to decrease. As a result, you may lose money on your investment in the Global Opportunities Fund, and there can be no assurance that the Global Opportunities Fund will achieve its investment objective. Each risk summarized below is considered a “principal risk” of investing in the Global Opportunities 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.

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

●

Company and Market Risk. The common stock of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer-than-expected earnings or management decisions, changes in the industry in which the company is engaged, or a reduction in the demand for a company’s products or services). 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 may adversely affect securities markets generally, which could adversely affect the value of the Global Opportunities Fund’s investments in common stocks. In addition, the rights of holders of common stock are subordinate to the rights of preferred shares and debt holders.

●

Foreign Investments Risk. The Global Opportunities Fund invests in the securities of foreign companies. Investing in securities of foreign companies involves risks generally not associated with investments in the securities of U.S. companies, including the risks associated with fluctuations in foreign currency exchange rates, less stringent investor protections, unreliable and untimely information about issuers, and political and economic instability. Foreign securities in which the Global Opportunities Fund invests may be traded in markets that close before the time that the Global Opportunities Fund calculates its net asset value (“NAV”). Furthermore, certain foreign securities in which the Global Opportunities Fund invests may be listed on foreign exchanges that trade on weekends or other days when the Global Opportunities Fund does not calculate its NAV. As a result, the value of the Global Opportunities Fund’s holdings may change on days when shareholders are not able to purchase or redeem the Global Opportunities Fund’s shares.

●

Investment Style Risk. The Global Opportunities Fund pursues a quality growth style of investing. Quality growth investing focuses on companies that appear attractively priced in light of factors such as the quality of management, sustainability of competitive advantage, or growth potential of cash flow. If the Adviser’s assessment of a company’s quality or intrinsic value or its prospects for exceeding earnings expectations or market conditions is inaccurate, the Global Opportunities Fund could suffer losses or produce poor performance relative to other funds. In addition, the stocks of quality companies can continue to be undervalued by the market for long periods of time.

As a consequence of our investing style we expect the Global Opportunities Fund will underperform the market and its peers over short timeframes.

●	Sector Risk. To the extent the Global Opportunities 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.

●

Financial Sector Risk. The operations and businesses of financial services companies are subject to extensive governmental regulation, the availability and cost of capital funds, and interest rate changes. General market downturns may affect financial services companies adversely.

●

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.

●

Currency Risk. Currency risk results from changes in the rate of exchange between the currency of the country in which a foreign company is domiciled or keeps its books and the U.S. dollar. Whenever the Global Opportunities Fund holds securities valued in a foreign currency or holds the currency itself in connection with its purchases and sales of foreign securities, changes in the exchange rate add to or subtract from the value of the investment in U.S. dollars. The Global Opportunities Fund generally does not seek to hedge currency risk, and although the Adviser considers currency risks as part of its investment process, its judgments in this regard may not always be correct.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Global Opportunities Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Global Opportunities 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 Global Opportunities Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The Global Opportunities Fund and the Adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Global Opportunities Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Global Opportunities Fund or its service providers may adversely impact and cause financial losses to the Global Opportunities Fund or its shareholders. Issuers of securities in which the Global Opportunities 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.

●

Depositary Receipts Risk. The Global Opportunities Fund may purchase depositary receipts (American Depositary Receipts (“ADRs”), European Depositary receipts (“EDRs”), Global Depositary receipts (“GDRs”), and Non-Voting Depositary Receipts (“NVDRs”)) to facilitate its investments in foreign securities. By investing in ADRs rather than investing directly in the securities of foreign issuers, the Global Opportunities Fund can avoid currency risks during the settlement period for purchase and sales. However, ADRs do not eliminate all the risks inherent in investing in the securities of foreign issuers. Depositary receipts may be issued in a sponsored program, in which an issuer has made arrangements to have its securities traded in the form of depositary receipts, or in an unsponsored program, in which the issuer may not be directly involved.

The holders of depositary receipts that are unsponsored generally bear various costs associated with the facilities, while a larger portion of the costs associated with sponsored depositary receipts are typically borne by the foreign issuers.

●

Emerging Market Countries Risk. Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign markets. In many less developed markets, there is less governmental supervision and regulation of business and industry practices, stock exchanges, brokers, and listed companies than there is in more developed markets. The securities markets of certain countries in which the Global Opportunities Fund may invest may also be smaller, less liquid, and subject to greater price volatility than those of more developed markets. The information available about an emerging market issuer may be less reliable than for comparable issuers in more developed capital markets. The Global Opportunities Fund seeks to invest no more than 50% of its net assets in emerging market countries.

●

ETF Risk. The Global Opportunities 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. Only an authorized participant (“APs”) may engage in creation or redemption transactions directly with the Fund. The Global Opportunities 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, Global Opportunities Fund Shares may trade at a material discount to NAV and possibly face delisting: (i) APs exit the business or otherwise become unable to process creation and/or redemption orders and no other APs step forward to perform these services, or (ii) market makers and/or liquidity providers exit the business or significantly reduce their business activities and no other entities step forward to perform their functions. These events, among others, may lead to the Global Opportunities Fund Shares trading at a premium or discount to NAV. 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, 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 Global Opportunities 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.

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

●

Small and Mid-Capitalization Companies Risk. The Global Opportunities Fund invests in securities of companies of all sizes, including those that have relatively small market capitalizations. Investments in securities of these companies involve greater risks than do investments in larger, more established companies. The prices of securities of small-cap companies tend to be more vulnerable to adverse developments specific to the company or its industry, or the securities markets generally, than are securities of larger capitalization companies.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

Performance Information: The bar chart and performance table below illustrate the risks and volatility of an investment in the Global Opportunities Fund. The Global Opportunities Fund has adopted the performance of the MFAM Global Opportunities Fund (the “Predecessor Fund”) as the result of a reorganization of the Predecessor Fund into the Global Opportunities Fund (the “Reorganization”). Prior to the Reorganization, the Global Opportunities Fund had not yet commenced operations. The Global Opportunities Fund’s total net operating expense ratio is lower than the net operating expense ratio of the Predecessor Fund. Returns in the bar chart and table for the Predecessor Fund have not been adjusted.

The Predecessor Fund, a series of The RBB Fund, Inc. that operated as a publicly sold open-end mutual fund, commenced operations on December 21, 2016 by acquiring the assets and liabilities of the Motley Fool Independence Fund, a series of The Motley Fool Funds Trust (the “MFFT Global Predecessor Fund”), in exchange for shares of the Predecessor Fund. Accordingly, the performance information shown below for periods prior to December 21, 2016 is that of the MFFT Global Predecessor Fund, which was also a publicly-sold open-end mutual fund. The MFFT Global Predecessor Fund was also advised by the Adviser and had the same investment objective and strategies as the Global Opportunities Fund and Predecessor Fund.

The bar chart shows the changes in performance of the Predecessor Fund from year to year. The table illustrates how the Predecessor Fund’s average annual total returns for the one-year, five-year and since inception periods compare with those of a broad measure of market performance. Past performance, both before and after taxes, does not necessarily indicate how the Global Opportunities Fund will perform in the future.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Mid-Cap Growth Fund is an actively-managed exchange-traded fund (“ETF”) and pursues its investment objective by using a quality growth investing style. The Mid-Cap Growth Fund invests in a focused portfolio of the common stocks of high-quality companies organized in the United States that are engaged in a broad range of industries.

Under normal market conditions, the Mid-Cap Growth Fund invests at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in securities issued by United States companies having mid-market capitalizations. For this purpose, Motley Fool Asset Management, LLC (the “Adviser”) currently defines mid-market capitalization companies as having similar market capitalizations to the companies in the Russell Midcap^® Growth Total Return Index, which is used for the purpose of determining range and not for targeting portfolio management. As of October 31, 2022, the average dollar-weighted market cap of the Russell Midcap Growth Total Return Index was approximately $24.2 billion. The median market cap was approximately $10.8 billion and the largest stock included in the index had a market cap of approximately $53.0 billion. Under normal circumstances, the Mid-Cap Growth Fund seeks to stay fully invested and does not attempt to time the market.

In identifying investments for the Mid-Cap Growth Fund, the Adviser looks for securities of companies that have high quality businesses with strong market positions, manageable leverage, robust streams of free cash flow, and trade at attractive prices. In managing the Mid-Cap Growth Fund’s investment portfolio, the Adviser regularly reviews and adjusts the Mid-Cap Growth Fund’s allocations to maintain a diversified mix of investments that the Adviser believes offer the best overall potential for long-term growth of capital. The Mid-Cap Growth Fund will sell securities in which it has invested based upon the Adviser’s analysis of fundamental investment criteria, including its assessment of the current value of a security relative to the security’s current market price, business fundamentals relating to the issuer, and developments affecting the issuer’s business prospects and risks.

The Mid-Cap Growth Fund prefers to invest in high-quality businesses when possible. To identify these high-quality businesses, the Adviser engages in research to evaluate each company under consideration using four criteria: management, culture, and incentives; the economics of the business; competitive advantage; and trajectory. The Adviser’s approach employs a long-term mindset and a balance of qualitative and quantitative factors.

Management, Culture, and Incentives.

The Adviser believes that management is a key element to long-term success at most businesses. Among the factors the Adviser considers are: manager and board of director fit, the clarity of vision and strategies, main-line culture and turnover, ownership in the business, the sensibility of incentives, capital allocation choices and results, external transparency and candor, and overall treatment of stakeholders.

Economics of the Business.

The Adviser believes that the economic performance of a business is a signal for quality. The Adviser’s process looks at the company’s long-term return on capital, the scalability of its business model, relative and absolute margins, business and product cyclicality, and other key performance indicators to gain insight into its potential for future performance.

Competitive Advantage.

The Adviser seeks companies that offer certain characteristics that allow them to generate and sustain outsized returns on capital on an absolute basis as well as in comparison to their peers. Competitive advantages may include pricing power, geographic barriers to entry, network effects, regulatory barriers to entry and superior brands, among others. The Adviser also assesses the strength of the supporting capabilities each company possesses that reinforce these advantages to result in unique positioning.

Trajectory

Companies often display superior economics over the short term due to favorable product cycles, customer preference, temporary or tactical advantages or other reasons. As the Adviser’s desire is to own companies in the Mid-Cap Growth Fund that can be kept in the portfolio for many years, a core part of the Adviser’s process is to consider what the company might look like over a period of ten or more years. The Adviser considers whether the company seems likely to grow, to increase profitability through additional products or other offerings, and if it has optionality and the financial capacity that may make it a larger, stronger business in the future than it might be today.

The Mid-Cap Growth Fund’s investment portfolio is focused, generally composed of at least 30 investment positions, with the 10 largest positions representing not more than 60% of the Mid-Cap Growth Fund’s net assets. To limit the risks associated with highly concentrated holdings, the Mid-Cap Growth Fund generally does not invest more than 5% of its net assets in securities of any one issuer at the time of purchase. If a portfolio holding grows to be greater than 5% of the Mid-Cap Growth Fund’s net assets the Adviser may not add additional capital to the position. However, the Adviser may maintain an allocation above 5% indefinitely, provided it continues to meet the Adviser’s investment criteria.

While investing in a particular sector is not a principal investment strategy of the Mid-Cap Growth 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. Currently, the Mid-Cap Growth Fund is significantly invested in the industrials sector, consumer discretionary sector, health care sector, and information technology sector, which means it will be more affected by the performance of such sectors than a fund that is not so significantly invested. The Fund may also seek to increase its income by lending portfolio securities.

The Mid-Cap Growth Fund has elected to be, and 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”).

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the Mid-Cap Growth Fund’s investments may decrease, which will cause the value of the Mid-Cap Growth Fund’s Shares to decrease. As a result, you may lose money on your investment in the Mid-Cap Growth Fund, and there can be no assurance that the Mid-Cap Growth Fund will achieve its investment objective. Each risk summarized below is considered a “principal risk” of investing in the Mid-Cap Growth Fund, regardless of the order in which it appears. The following are the principal risks that could affect the value of your investment:

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

●

Company and Market Risk. The common stock of a company may not perform as well as expected, and may decrease in value, because of factors related to the company (such as poorer-than-expected earnings or management decisions, changes in the industry in which the company is engaged, or a reduction in the demand for a company’s products or services). 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 may adversely affect securities markets generally, which could adversely affect the value of the Mid-Cap Growth Fund’s investments in common stocks. In addition, the rights of holders of common stock are subordinate to the rights of preferred shares and debt holders.

●

Investment Style Risk. The Mid-Cap Growth Fund pursues a quality growth style of investing. Quality growth investing focuses on companies that appear attractively priced in light of factors such as the quality of management, sustainability of competitive advantage, or growth potential of cash flow. If the Adviser’s assessment of a company’s quality or intrinsic value or its prospects for exceeding earnings expectations or market conditions is inaccurate, the Mid-Cap Growth Fund could suffer losses or produce poor performance relative to other funds. In addition, the stocks of quality companies can continue to be undervalued by the market for long periods of time. As a consequence of our investing style we expect the Mid-Cap Growth Fund will underperform the market and its peers over short time frames.

●	Sector Risk. To the extent the Mid-Cap Growth 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.

●

Mid-Capitalization Companies Risk. The Mid-Cap Growth Fund invests in securities of mid-capitalization companies. Investments in securities of these 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.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the Mid-Cap Growth Fund’s assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Mid-Cap Growth 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 Mid-Cap Growth Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The Mid-Cap Growth Fund and the Adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Mid-Cap Growth Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the Mid-Cap Growth Fund or its service providers may adversely impact and cause financial losses to the Mid-Cap Growth Fund or its shareholders. Issuers of securities in which the Mid-Cap Growth 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 Mid-Cap Growth 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Mid-Cap Growth Fund has a limited number of financial institutions that are institutional investors and may act as 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, Mid-Cap Growth 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 Mid-Cap Growth Fund Shares trading at a premium or discount to NAV. 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, the Cboe BZX Exchange, 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 Mid-Cap Growth 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.

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

rr_PerformanceNarrativeTextBlock

Performance Information: The bar chart and performance table below illustrate the risks and volatility of an investment in the Mid-Cap Growth Fund. The Mid-Cap Growth Fund has adopted the performance of the MFAM Mid-Cap Growth Fund (the “Predecessor Fund”) as the result of a reorganization of the Predecessor Fund into the Mid-Cap Growth Fund (the “Reorganization”). Prior to the Reorganization, the Mid-Cap Growth Fund had not yet commenced operations. The Mid-Cap Growth Fund’s total net operating expense ratio is lower than the net operating expense ratio of the Predecessor Fund. Returns in the bar chart and table for the Predecessor Fund have not been adjusted.

The Predecessor Fund, a series of The RBB Fund, Inc. that operated as a publicly sold open-end mutual fund, commenced operations on December 21, 2016 by acquiring the assets and liabilities of the Motley Fool Great America Fund, a series of The Motley Fool Funds Trust (the “MFFT GA Predecessor Fund”), in exchange for shares of the Predecessor Fund. Accordingly, the performance information shown below for periods prior to December 21, 2016 is that of the MFFT GA Predecessor Fund, which was also a publicly-sold open-end mutual fund. The MFFT GA Predecessor Fund was also advised by the Adviser and had the same investment objective and strategies as the Mid-Cap Growth Fund and Predecessor Fund.

The bar chart shows the changes in performance of the Predecessor Fund from year to year. The table illustrates how the Predecessor Fund’s average annual total returns for the one-year, five-year and since-inception periods compare with those of a broad measure of market performance. Past performance, both before and after taxes, does not necessarily indicate how the Mid-Cap Growth Fund will perform in the future.

In certain cases, the figure representing “Return after Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period, since a higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

The Motley Fool Next Index ETF (the “Next Fund”) seeks investment results that correspond (before fees and expenses) generally to the total return performance of the Motley Fool Next Index (the “Next Index” – for more on this, see the “Principal Investment Strategies” section).

Expense Narrative [Text Block]

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 hold or 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:

Strategy Narrative [Text Block]

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 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”).

Risk Narrative [Text Block]

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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The Next Fund has a limited number of financial institutions that are institutional investors and may act as 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. In periods of market volatility, APs, market makers and/or liquidity providers may be less willing to transact in Fund Shares.

●

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 a limited 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.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

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.

Portfolio Turnover [Text Block]

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, 2022, the Fund’s portfolio turnover rate was 133% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 the Class A Shares or Class C Shares or $1,000,000 in the Class I Shares of the Fund and for the time periods indicated and then hold or 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 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:

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities, primarily common stocks, of companies within the Russell 1000^® Index and S&P 500^® Index. 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 in the U.S. on registered exchanges or the over-the-counter market. The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”).

The Adviser attempts to lower the Fund’s market risk by investing in U.S. equity securities that 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. The Fund invests in stocks that often 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.

Risk Narrative [Text Block]

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. 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.

■

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.

■

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 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 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 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.

■

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.

■

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 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 net asset value (“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 investment selection. In other words, the individual investments of 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.

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 year-to-date total return for the nine months ended September 30, 2022 was -20.87%.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in equity securities, primarily common stocks of U.S. issuers with small market capitalizations. A small market capitalization issuer generally is considered to be one whose market capitalization is, at the time the Fund makes the investment, similar to the market capitalization of companies in the Russell 2000^® Index. The Russell 2000^® Index is a small cap stock market index measuring the performance of approximately 2,000 small cap U.S. companies. As of August 31, 2022, the minimum market capitalization of the Russell 2000^® Index was $355.1 million and the largest stock was $10.7 billion. 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 in the U.S. on registered exchanges or the over-the-counter market. The Fund may also invest in other registered investment companies, including exchange-traded funds (“ETFs”), and may invest in real estate investment trusts (“REITs”).

The Adviser attempts to lower the Fund’s market risk by investing in U.S. equity securities that lower the overall volatility of the Fund’s portfolio as compared to the Russell 2000^® Index. 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 often 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.

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 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 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.

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 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.

■

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 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 net asset value (“NAV”).

■

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.

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.

■

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.

■

REITs Risk. The Fund’s investments in REITs may be affected by economic forces and other factors related to the real estate industry. These risks include possible declines in the value of real estate, possible lack of availability of mortgage funds and unexpected vacancies of properties. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidating interest rate risks (especially mortgage REITs) and liquidity risk. REITs that invest in real estate mortgages are also subject to prepayment risk. Investing in REITs may involve risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume, engage in dilutive offerings, and may be subject to more abrupt or erratic price movements than the securities of larger companies. Historically, small capitalization stocks, such as REITs, have been more volatile in price than the larger capitalization stocks included in the S&P 500^® Index.

■

Small Cap Risk. Stocks of small companies 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 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.

■

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.

Portfolio Turnover [Text Block]

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. 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, 2022, the Fund’s portfolio turnover rate was 87% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 hold or 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 (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:

Strategy Narrative [Text Block]

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.

Risk Narrative [Text Block]

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 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 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 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 net asset value (“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 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 investment selection. In other words, the individual investments of 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.

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 held or 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:

Strategy Narrative [Text Block]

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.

Risk Narrative [Text Block]

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 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 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 net asset value (“NAV”).

■

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.

■

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.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.

Performance Table Explanation after Tax Higher

rr_PerformanceTableExplanationAfterTaxHigher

In certain cases, the figure representing “Return after Taxes on Distributions and Sale of Fund Shares” may be higher than the other return figures for the same period, since a higher after-tax return results when a capital loss occurs upon redemption and provides an assumed tax deduction that benefits the investor.

Portfolio Turnover [Text Block]

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, 2022, the Fund’s portfolio turnover rate was 67% of the average value of its portfolio.

Expense Example Narrative [Text Block]

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 hold or 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 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:

Strategy Narrative [Text Block]

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 focused on domestic equities, a lesser amount in Underlying Funds focused on large capitalization foreign equities, mid-capitalization foreign equities, emerging markets and domestic investment-grade bonds, and a small amount in Underlying Funds focused on small-capitalization foreign equities, domestic high yield bonds, foreign investment-grade and high yield bonds, and money market funds.

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. 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.

Risk Narrative [Text Block]

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 the 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. In addition, investments in certain emerging markets are subject to an elevated risk of loss resulting from market manipulation and the imposition of exchange controls (including repatriation restrictions). The legal rights and remedies available for investors in emerging markets may be more limited than the rights and remedies available in the U.S., and the ability of U.S. authorities (e.g., SEC and the U.S. Department of Justice) to bring actions against bad actors in emerging markets may be limited.

■

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’s adviser’s perceptions of a company’s growth potential is 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 investment 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.

■

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. The SEC has adopted revisions to the rules permitting funds to invest in other investment companies to streamline and enhance the regulatory framework applicable to fund of funds arrangements. While Rule 12d1-4 permits more types of fund of fund arrangements without reliance on an exemptive order or no-action letters, it imposes new conditions, including limits on control and voting of acquired funds’ shares, evaluations and findings by investment advisers, fund investment agreements, and limits on most three-tier fund structures. Rule 12d1-4 went into effect on January 19, 2021. The rescission of the applicable exemptive orders and the withdrawal of the applicable no-action letters was effective on January 19, 2022.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The UST 10 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 10-Year US Treasury Index (GA10) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 10 Year Note Fund’s investment objective by investing at least 80% of the UST 10 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index. The Fund may enter into reverse repurchase agreements in amounts not exceeding one-third of the Fund’s total assets (including the amount borrowed).

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 10-Year US Treasury Index is a one-security index comprised of the most recently issued 10-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 10-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities).

This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 10 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 10 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 10 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 10 Year Note Fund track the Underlying Index.

The UST 10 Year Note Fund has elected 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 Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the UST 10 Year Note Fund’s investments may decrease, which will cause the value of the UST 10 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 10 Year Note Fund, and there can be no assurance that the UST 10 Year Note Fund will achieve its investment objective. The UST 10 Year Note 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 UST 10 Year Note 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.

●

Concentration Risk. The UST 10 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 10 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 10 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 10 Year Note Fund’s assets, UST 10 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 10 Year Note 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 UST 10 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 10 Year Note 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 UST 10 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 10 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 10 Year Note Fund or its shareholders. Issuers of securities in which the UST 10 Year Note 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.

●

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

●

ETF Risk. The UST 10 Year Note 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The UST 10 Year Note Fund has a limited number of financial institutions that are institutional investors and may act as 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, UST 10 Year Note 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 UST 10 Year Note 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 UST 10 Year Note 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (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 UST 10 Year Note 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.

●

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in UST 10 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 10 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 10 Year Note Fund’s share price and increase the UST 10 Year Note Fund’s liquidity risk, UST 10 Year Note Fund expenses and/or taxable distributions.

●

Income Risk. The UST 10 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 10 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 10 Year Note Fund otherwise needs to purchase additional bonds.

●

Index Related Risk. There is no guarantee that the UST 10 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 10 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 10 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 10 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

●

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 10 Year Note Fund receives from it but will generally affect the value of your investment in the UST 10 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 10 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 10 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 10 Year Note Fund’s performance will be negatively impacted. The UST 10 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 10 Year Note Fund, resulting in a negative impact on the UST 10 Year Note Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 10 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 10 Year Note Fund, which may force the UST 10 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 10 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 10 Year Note Fund is a newly organized, management investment company with a limited operating history. In addition, there can be no assurance that the UST 10 Year Note 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 UST 10 Year Note Fund.

●

Passive Investment Risk. The UST 10 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 10 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 10 Year Note Fund generally does not attempt to invest the UST 10 Year Note Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 10 Year Note Fund’s portfolio will decline if and when the UST 10 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 10 Year Note Fund may be subject to tracking error, which is the divergence of the UST 10 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 10 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 10 Year Note Fund, the UST 10 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 10 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 10 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

Such actions may negatively affect the value of debt instruments held by the UST 7 Year Note Fund, resulting in a negative impact on the UST 7 Year Note Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 7 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 7 Year Note Fund, which may force the UST 7 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 7 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 7 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 7 Year Note 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 UST 7 Year Note Fund.

●

Passive Investment Risk. The UST 7 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 7 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 7 Year Note Fund generally does not attempt to invest the UST 7 Year Note Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 7 Year Note Fund’s portfolio will decline if and when the UST 7 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 7 Year Note Fund may be subject to tracking error, which is the divergence of the UST 7 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 7 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 7 Year Note Fund, the UST 7 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 7 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 7 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The UST 5 Year Note Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA Current 5-Year US Treasury Index (GA05) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 5 Year Note Fund’s investment objective by investing at least 80% of the UST 5 Year Note Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index. The Fund may enter into reverse repurchase agreements in amounts not exceeding one-third of the Fund’s total assets (including the amount borrowed).

The Underlying Index

The Underlying Index was established December 31, 1987 by ICE Data Services (the “Index Provider”). The ICE BofA Current 5-Year US Treasury Index is a one-security index comprised of the most recently issued 5-year US Treasury note. The index is rebalanced monthly. In order to qualify for inclusion, a 5-year note must be auctioned on or before the third business day before the last business day of the month. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities).

This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 5 Year Note Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 5 Year Note Fund’s investment strategy is to pursue its investment objective. The UST 5 Year Note Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 5 Year Note Fund track the Underlying Index.

The UST 5 Year Note Fund has elected 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 Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the UST 5 Year Note Fund’s investments may decrease, which will cause the value of the UST 5 Year Note Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 5 Year Note Fund, and there can be no assurance that the UST 5 Year Note Fund will achieve its investment objective. The UST 5 Year Note 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 UST 5 Year Note 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.

●

Concentration Risk. The UST 5 Year Note Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 5 Year Note Fund’s investments more than the market as a whole, to the extent that the UST 5 Year Note Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 5 Year Note Fund’s assets, UST 5 Year Note Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 5 Year Note 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 UST 5 Year Note Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 5 Year Note 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 UST 5 Year Note Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 5 Year Note Fund or its service providers may adversely impact and cause financial losses to the UST 5 Year Note Fund or its shareholders. Issuers of securities in which the UST 5 Year Note 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.

●

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

●

ETF Risk. The UST 5 Year Note 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The UST 5 Year Note Fund has a limited number of financial institutions that are institutional investors and may act as 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, UST 5 Year Note 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 UST 5 Year Note 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 UST 5 Year Note 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (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 UST 5 Year Note 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.

●

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in UST 5 Year Note Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 5 Year Note Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 5 Year Note Fund’s share price and increase the UST 5 Year Note Fund’s liquidity risk, UST 5 Year Note Fund expenses and/or taxable distributions.

●

Income Risk. The UST 5 Year Note Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 5 Year Note Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 5 Year Note Fund otherwise needs to purchase additional bonds.

●

Index Related Risk. There is no guarantee that the UST 5 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 5 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 5 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 5 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

●

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 5 Year Note Fund receives from it but will generally affect the value of your investment in the UST 5 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 5 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 5 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 5 Year Note Fund’s performance will be negatively impacted. The UST 5 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 5 Year Note Fund, resulting in a negative impact on the UST 5 Year Note Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 5 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 5 Year Note Fund, which may force the UST 5 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 5 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 5 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 5 Year Note 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 UST 5 Year Note Fund.

●

Passive Investment Risk. The UST 5 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 5 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 5 Year Note Fund generally does not attempt to invest the UST 5 Year Note Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 5 Year Note Fund’s portfolio will decline if and when the UST 5 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 5 Year Note Fund may be subject to tracking error, which is the divergence of the UST 5 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 5 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 5 Year Note Fund, the UST 5 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 5 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 5 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

Index Related Risk. There is no guarantee that the UST 3 Year Note Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 3 Year Note Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 3 Year Note Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 3 Year Note Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

●

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 3 Year Note Fund receives from it but will generally affect the value of your investment in the UST 3 Year Note Fund. Changes in interest rates may also affect the liquidity of the UST 3 Year Note Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 3 Year Note Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 3 Year Note Fund’s performance will be negatively impacted. The UST 3 Year Note Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 3 Year Note Fund, resulting in a negative impact on the UST 3 Year Note Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 3 Year Note Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 3 Year Note Fund, which may force the UST 3 Year Note Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 3 Year Note Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 3 Year Note Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 3 Year Note 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 UST 3 Year Note Fund.

●

Passive Investment Risk. The UST 3 Year Note Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 3 Year Note Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 3 Year Note Fund generally does not attempt to invest the UST 3 Year Note Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 3 Year Note Fund’s portfolio will decline if and when the UST 3 Year Note Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 3 Year Note Fund may be subject to tracking error, which is the divergence of the UST 3 Year Note Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 3 Year Note Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 3 Year Note Fund, the UST 3 Year Note Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 3 Year Note Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 3 Year Note Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The UST 12 Month Bill Fund is a passively-managed exchange-traded fund (“ETF”) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the ICE BofA US 1-Year Treasury Bill Index (G0O3) (“Underlying Index”). Under normal market conditions, F/m Investments, LLC d/b/a North Slope Capital, LLC (the “Adviser”) seeks to achieve the UST 12 Month Bill Fund’s investment objective by investing at least 80% of the UST 12 Month Bill Fund’s net assets (plus any borrowings for investment purposes) in the component securities of the Underlying Index. The Fund may enter into reverse repurchase agreements in amounts not exceeding one-third of the Fund’s total assets (including the amount borrowed).

The Underlying Index

The Underlying Index was established May 31, 1991 by ICE Data Services (the “Index Provider”). The Underlying Index is comprised of a single issue purchased at the beginning of the month and held for a full month. At the end of the month that issue is sold and rolled into a newly selected issue. The issue selected at each month-end rebalancing is the outstanding Treasury Bill that matures closest to, but not beyond, 1 year from the rebalancing date. To qualify for selection, an issue must have settled on or before the month-end rebalancing date. The components of the Underlying Index change at the start of the month following any month when there has been a new public sale by the U.S. Government (referred to as an “auction”) of an underlying Treasury Security (or Securities).

This periodic transition to the most-recently auctioned Treasury bill, note, or bond of a stated maturity, which is referred to as the “on-the-run” or “OTR” security of that maturity, occurs on one day. An OTR security is the most recently issued of a periodically issued security (as opposed to an off-the-run security, which is a security that has been issued before the most recent issue and is still outstanding).

The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the UST 12 Month Bill Fund or the Adviser. Additional information regarding the Underlying Index, including its value, is available at https://indices.theice.com/. The UST 12 Month Bill Fund’s investment strategy is to pursue its investment objective. The UST 12 Month Bill Fund generally may invest up to 20% of its total assets in securities or other investments not included in the Underlying Index, but which the Adviser believes will help the UST 12 Month Bill Fund track the Underlying Index.

The UST 12 Month Bill Fund has elected 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 Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the UST 12 Month Bill Fund’s investments may decrease, which will cause the value of the UST 12 Month Bill Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 12 Month Bill Fund, and there can be no assurance that the UST 12 Month Bill Fund will achieve its investment objective. The UST 12 Month Bill 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 UST 12 Month Bill 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.

●

Concentration Risk. The UST 12 Month Bill Fund may be susceptible to an increased risk of loss, including losses due to adverse events that affect the UST 12 Month Bill Fund’s investments more than the market as a whole, to the extent that the UST 12 Month Bill Fund’s investments are concentrated in a particular issue, issuer or issuers, country, market segment, or asset class.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 12 Month Bill Fund’s assets, UST 12 Month Bill Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 12 Month Bill 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 UST 12 Month Bill Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 12 Month Bill 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 UST 12 Month Bill Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 12 Month Bill Fund or its service providers may adversely impact and cause financial losses to the UST 12 Month Bill Fund or its shareholders. Issuers of securities in which the UST 12 Month Bill 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.

●

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

●

ETF Risk. The UST 12 Month Bill 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Funds. The UST 12 Month Bill Fund has a limited number of financial institutions that are institutional investors and may act as 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, UST 12 Month Bill 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 UST 12 Month Bill 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 UST 12 Month Bill 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (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 UST 12 Month Bill 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.

●

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in UST 12 Month Bill Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 12 Month Bill Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 12 Month Bill Fund’s share price and increase the UST 12 Month Bill Fund’s liquidity risk, UST 12 Month Bill Fund expenses and/or taxable distributions.

●

Income Risk. The UST 12 Month Bill Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 12 Month Bill Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 12 Month Bill Fund otherwise needs to purchase additional bonds.

●

Index Related Risk. There is no guarantee that the UST 12 Month Bill Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 12 Month Bill Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 12 Month Bill Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 12 Month Bill Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

●

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 12 Month Bill Fund receives from it but will generally affect the value of your investment in the UST 12 Month Bill Fund. Changes in interest rates may also affect the liquidity of the UST 12 Month Bill Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 12 Month Bill Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 12 Month Bill Fund’s performance will be negatively impacted. The UST 12 Month Bill Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 12 Month Bill Fund, resulting in a negative impact on the UST 12 Month Bill Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 12 Month Bill Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 12 Month Bill Fund, which may force the UST 12 Month Bill Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 12 Month Bill Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 12 Month Bill Fund is a newly organized, management investment company with a limited operating history. In addition, there can be no assurance that the UST 12 Month Bill 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 UST 12 Month Bill Fund.

●

Passive Investment Risk. The UST 12 Month Bill Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 12 Month Bill Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 12 Month Bill Fund generally does not attempt to invest the UST 12 Month Bill Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 12 Month Bill Fund’s portfolio will decline if and when the UST 12 Month Bill Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 12 Month Bill Fund may be subject to tracking error, which is the divergence of the UST 12 Month Bill Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 12 Month Bill Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 12 Month Bill Fund, the UST 12 Month Bill Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 12 Month Bill Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 12 Month Bill Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The value of the UST 6 Month Bill Fund’s investments may decrease, which will cause the value of the UST 6 Month Bill Fund’s Shares to decrease. As a result, you may lose money on your investment in the UST 6 Month Bill Fund, and there can be no assurance that the UST 6 Month Bill Fund will achieve its investment objective. The UST 6 Month Bill 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 UST 6 Month Bill Fund, regardless of the order in which it appears.

●

Cyber Security Risk. Cyber security risk is the risk of an unauthorized breach and access to the UST 6 Month Bill Fund’s assets, UST 6 Month Bill Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the UST 6 Month Bill 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 UST 6 Month Bill Fund’s investors from purchasing, redeeming or exchanging shares or receiving distributions. The UST 6 Month Bill 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 UST 6 Month Bill Fund or the Adviser. Successful cyber-attacks or other cyber-failures or events affecting the UST 6 Month Bill Fund or its service providers may adversely impact and cause financial losses to the UST 6 Month Bill Fund or its shareholders. Issuers of securities in which the UST 6 Month Bill 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.

●

Duration Risk. Duration is a measure of the price sensitivity of a debt security or portfolio to interest rate changes. Duration risk is the risk that longer-duration debt securities will be more volatile and thus more likely to decline in price, and to a greater extent, in a rising interest rate environment than shorter-duration debt securities.

●

ETF Risk. The UST 6 Month Bill 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. Only an authorized participant (“AP”) may engage in creation or redemption transactions directly with the Fund. The UST 6 Month Bill Fund has a limited number of financial institutions that are institutional investors and may act as 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, UST 6 Month Bill 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 UST 6 Month Bill 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 UST 6 Month Bill 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.

●

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, Nasdaq Stock Market, LLC (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 UST 6 Month Bill 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.

●

Fixed-Income Market Risk. The market value of a fixed-income security may decline due to general market conditions that are not specifically related to a particular issuer, such as real or perceived adverse economic conditions, changes in the outlook for corporate earnings, changes in interest or currency rates or adverse investor sentiment generally. The fixed-income securities market can be susceptible to increases in volatility and decreases in liquidity. Liquidity can decline unpredictably in response to overall economic conditions or credit tightening. Increases in volatility and decreases in liquidity may be caused by a rise in interest rates (or the expectation of a rise in interest rates). An unexpected increase in UST 6 Month Bill Fund redemption requests, including requests from shareholders who may own a significant percentage of the fund’s shares, which may be triggered by market turmoil or an increase in interest rates, could cause the UST 6 Month Bill Fund to sell its holdings at a loss or at undesirable prices and adversely affect the UST 6 Month Bill Fund’s share price and increase the UST 6 Month Bill Fund’s liquidity risk, UST 6 Month Bill Fund expenses and/or taxable distributions.

●

Income Risk. The UST 6 Month Bill Fund’s income may decline if interest rates fall. This decline in income can occur because the UST 6 Month Bill Fund may subsequently invest in lower yielding bonds as bonds in its portfolio mature, are near maturity or are called, bonds in the Underlying Index are substituted, or the UST 6 Month Bill Fund otherwise needs to purchase additional bonds.

●

Index Related Risk. There is no guarantee that the UST 6 Month Bill Fund’s investment results will have a high degree of correlation to those of the Underlying Index or that the UST 6 Month Bill Fund will achieve its investment objective. Market disruptions and regulatory restrictions could have an adverse effect on the UST 6 Month Bill Fund’s ability to adjust its exposure to the required levels in order to track the Underlying Index. Errors in index data, index computations or the construction of the Underlying Index in accordance with its methodology may occur from time to time and may not be identified and corrected by the Index Provider for a period of time or at all, which may have an adverse impact on the UST 6 Month Bill Fund and its shareholders. Unusual market conditions may cause the Index Provider to postpone a scheduled rebalance, which could cause the Underlying Index to vary from its normal or expected composition.

●

Interest Rate Risk. Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if prevailing interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the UST 6 Month Bill Fund receives from it but will generally affect the value of your investment in the UST 6 Month Bill Fund. Changes in interest rates may also affect the liquidity of the UST 6 Month Bill Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk. Very low or negative interest rates may impact the UST 6 Month Bill Fund’s yield and may increase the risk that, if followed by rising interest rates, the UST 6 Month Bill Fund’s performance will be negatively impacted. The UST 6 Month Bill Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Such actions may negatively affect the value of debt instruments held by the UST 6 Month Bill Fund, resulting in a negative impact on the UST 6 Month Bill Fund’s performance and NAV. Any interest rate increases could cause the value of the UST 6 Month Bill Fund’s investments in debt instruments to decrease. Rising interest rates may prompt redemptions from the UST 6 Month Bill Fund, which may force the UST 6 Month Bill Fund to sell investments at a time when it is not advantageous to do so, which could result in losses.

●

Market Risk. The trading prices of securities and other instruments fluctuate in response to a variety of factors. The UST 6 Month Bill Fund’s NAV and market price may fluctuate significantly in response to these and other 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. As a result, an investor could lose money over short or long periods of time.

●

New Fund Risk. The UST 6 Month Bill Fund is a newly organized, management investment company with no operating history. In addition, there can be no assurance that the UST 6 Month Bill 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 UST 6 Month Bill Fund.

●

Passive Investment Risk. The UST 6 Month Bill Fund is not actively managed and may be affected by a general decline in market segments related to the Underlying Index. The UST 6 Month Bill Fund invests in securities included in, or representative of, the Underlying Index, regardless of their investment merits. The UST 6 Month Bill Fund generally does not attempt to invest the UST 6 Month Bill Fund’s assets in defensive positions under any market conditions, including declining markets.

●

Reinvestment Risk. Reinvestment risk is the risk that income from the UST 6 Month Bill Fund’s portfolio will decline if and when the UST 6 Month Bill Fund reinvests the proceeds from the disposition of its portfolio securities at market interest rates that are below the portfolio’s current earnings rate. A decline in income could negatively affect the market price of the Shares.

●

Reverse Repurchase Agreements Risk. Reverse repurchase agreements are a form of secured borrowing and subject the Fund to the risks associated with leverage, including exposure to potential gains and losses in excess of the amount invested, resulting in an increase in the speculative character of the Fund’s outstanding shares. Reverse repurchase agreements involve the risk that the investment return earned by the Fund (from the investment of the proceeds) will be less than the interest expense of the transaction, that the market value of the securities sold by the Fund will decline below the price the Fund is obligated to pay to repurchase the securities, and that the other party may fail to return the securities in a timely manner or at all.

●

Tracking Error Risk. The UST 6 Month Bill Fund may be subject to tracking error, which is the divergence of the UST 6 Month Bill Fund’s performance from that of the Underlying Index. Tracking error may occur because of differences between the securities and other instruments held in the UST 6 Month Bill Fund’s portfolio and those included in the Underlying Index, pricing differences, transaction costs incurred by the UST 6 Month Bill Fund, the UST 6 Month Bill Fund’s holding of uninvested cash, differences in timing of the accrual of or the valuation of distributions, the requirements to maintain pass-through tax treatment, portfolio transactions carried out to minimize the distribution of capital gains to shareholders, acceptance of custom baskets, changes to the Underlying Index or the costs to the UST 6 Month Bill Fund of complying with various new or existing regulatory requirements. This risk may be heightened during times of increased market volatility or other unusual market conditions. Tracking error also may result because the UST 6 Month Bill Fund incurs fees and expenses, while the Underlying Index does not.

●

U.S. Government Obligations Risk. While U.S. Treasury obligations are backed by the “full faith and credit” of the U.S. Government, such securities are nonetheless subject to credit risk (i.e., the risk that the U.S. Government may be, or be perceived to be, unable or unwilling to honor its financial obligations, such as making payments). Securities issued or guaranteed by federal agencies or authorities and U.S. Government-sponsored instrumentalities or enterprises may or may not be backed by the full faith and credit of the U.S. Government.
