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, 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 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.

•

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 hold 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. 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 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 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.

◦

Secondary Market Trading Risk. Although Shares are listed on a national securities exchange, 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 is adopting 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 ten-year 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.

The Mid-Cap Growth 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 Mid-Cap Growth Fund Shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Mid-Cap Growth Fund’s performance. For the fiscal year ended August 31, 2021, the Predecessor Fund’s (defined below) portfolio turnover rate was 15% of the average value of its portfolio.
