The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses (including capped expenses for the period described in the footnote to the fee table) 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 invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes in equity securities of developed market companies. This investment policy may be changed by the Fund upon 60 days’ prior written notice to shareholders.

The Adviser considers a company to be a developed market company if it is organized or maintains its principal place of business in a developed markets country. The Adviser considers a country to be a developed markets country if the country is represented in the MSCI World Index or another widely recognized developed markets index. As of November 30, 2021, the MSCI World Index consisted of the following 23 developed markets countries: Austria, Australia, Belgium, Canada, Denmark, Finland, France, Hong Kong, Germany, Ireland, Israel, Italy, Japan, Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland, United Kingdom and the United States. The Fund's investment allocation to countries and regions tends to closely approximate the country and region allocations of the MSCI World Index, which may focus its exposure in one or more countries or regions. Developed markets are often characterized by high levels of gross domestic product (GDP) per capita and mature financial institutions.

The equity securities in which the Fund invests are primarily common stocks and depositary receipts, including unsponsored depositary receipts, but may also include preferred stocks, exchange-traded funds (“ETFs”), and securities of other investment companies. The Fund may invest in securities of companies with any market capitalization with a particular focus on mid- and large-capitalization securities.

The Fund is primarily made up of stocks from developed markets that are selected using a quantitative investment approach with human discretion. In quantitative investment strategies, investment decisions are made using large amounts of data and computer models. However, the Adviser has the discretion to adjust trades based on news, liquidity, or additional insights from the Adviser’s portfolio management team. The Adviser’s quantitative investment model allocates more weight to stocks for which the model identifies the potential for higher future returns, taking into account risk (i.e., risk-adjusted returns), and less weight to stocks for which the model identifies the potential for lower future risk-adjusted returns. The Adviser’s portfolio management team may adjust portfolio weights for the Fund based on their own analysis of the securities in the Fund’s investment universe in order to enhance evaluations made by the quantitative model. In addition to excluding stocks in specific countries as a result of the Fund’s investment models, the Adviser may avoid investing in a given country for which the transaction costs of investing exceed the benefits of investing in that country. Due to its investment strategy, the Fund may buy and sell securities frequently.The Adviser uses data from a variety of sources, including data purchased from vendors and data accessed by the Adviser from alternative sources (e.g., data collected from public websites). Such data are collected at varying frequencies (e.g., daily price data, quarterly financial statements) and considered over varying horizons, ranging from months to years, depending on the nature of the data in question. The Adviser employs a proprietary data cleaning process, whereby data obtained from vendors and other sources is inspected for errors, processed to make information obtained from different sources useful in comparing various companies, sectors, and markets, and formatted for inclusion in the Adviser’s database and for use in its models. The Adviser monitors its data and models through a combination of automated and manual checks. The Adviser pays for data used in the strategy’s models.

The Adviser also takes into account certain environmental, social, and governance (“ESG”) criteria in choosing and weighting investments in the Fund, basing its evaluation on a combination of third-party data and proprietary metrics. ESG considerations that will impact the quantitative ranking of stocks include (but are not limited to) evaluations of firms’ financial reporting practices (e.g., reducing the weight of companies suspected of manipulative accounting) and the degree of alignment between a firm’s managers and shareholders (e.g., whether managers are prone to wastefully reinvest the company’s earnings rather than distributing earnings to shareholders). Governance characteristics will lead to either an increase or decrease of weight in a stock, depending on whether the Adviser determines that the company exhibits good or bad governance, respectively, on the basis of that characteristic. In addition, the Fund will screen out the stock of companies that are identified by the Adviser as having extremely poor environmental performance (e.g., firms with exceedingly high CO2 emissions, energy intensity, water intensity, and waste generation). Such exclusions will be made regardless of the expected future returns of stocks failing to meet the Fund’s ESG screening criteria. Because the Fund’s universe of stocks is large relative to the number of companies expected by the Adviser to fail their ESG criteria, the Adviser does not expect screening on ESG to have a significant impact on the Fund’s ability to meet its investment objective.

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

As with all mutual funds, there is no guarantee that the Fund will achieve its investment objective. You could lose money by investing in the Fund. A Fund share is not a bank deposit and it is not insured or guaranteed by the FDIC or any other government agency. The principal risk factors affecting shareholders’ investments in the Fund are set forth below.

Equity Market Risk – The risk that stock prices will fall over short or extended periods of time, sometimes rapidly and unpredictably. The value of equity securities will fluctuate in response to factors affecting a particular company, as well as broader market and economic conditions. Broad movements in financial markets may adversely affect the price of the Fund’s investments, regardless of how well the companies in which the Fund invests perform. In addition, the impact of any epidemic, pandemic or natural disaster, or widespread fear that such events may occur, could negatively affect the global economy, as well as the economies of individual countries, the financial performance of individual companies and sectors, and the markets in general in significant and unforeseen ways. Any such impact could adversely affect the prices and liquidity of the securities and other instruments in which the Fund invests, which in turn could negatively impact the Fund’s performance and cause losses on your investment in the Fund. Moreover, in the event of a company’s bankruptcy, claims of certain creditors, including bondholders, will have priority over claims of common stock holders such as the Fund.

Foreign Company Risk – Investing in foreign companies, including direct investments and investments through ADRs, poses additional risks since political and economic events unique to a country or region will affect those markets and their issuers. These risks will not necessarily affect the U.S. economy or similar issuers located in the United States. Securities of foreign companies may not be registered with the U.S. Securities and Exchange Commission (the “SEC”) and foreign companies are generally not subject to the same level of regulatory controls imposed on U.S. issuers and, as a consequence, there is generally less publicly available information about foreign securities than is available about domestic securities. Income from foreign securities owned by the Fund may be reduced by a withholding tax at the source, which tax would reduce income received from the securities comprising the Fund’s portfolio. Foreign securities may also be more difficult to value than securities of U.S. issuers and foreign markets and securities may be less liquid. In addition, periodic U.S. Government restrictions on investments in issuers from certain foreign countries may require the Fund to sell such investments at inopportune times, which could result in losses to the Fund. While ADRs provide an alternative to directly purchasing the underlying foreign securities in their respective national markets and currencies, investments in ADRs continue to be subject to many of the risks associated with investing directly in foreign securities.

Foreign Currency Risk – As a result of the Fund’s investments in securities denominated in, and/or receiving revenues in, foreign currencies, the Fund will be subject to currency risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar, in which case the dollar value of an investment in the Fund would be adversely affected.

Large Capitalization Risk – The risk that larger, more established companies may be unable to respond quickly to new competitive challenges such as changes in technology and consumer tastes. Larger companies also may not be able to attain the high growth rates of successful smaller companies.

Small and Medium Capitalization Companies Risk – The risk that small and medium capitalization companies in which the Fund may invest may be more vulnerable to adverse business or economic events than larger, more established companies. In particular, small and medium capitalization companies may have limited product lines, markets and financial resources and may depend upon a relatively small management group. Therefore, small capitalization and medium capitalization stocks may be more volatile than those of larger companies. Small capitalization and medium capitalization stocks may be traded over-the-counter or listed on an exchange.

Geographic Focus Risk – Because the Fund's investment allocation to countries and regions tends to closely approximate the country and region allocations of the MSCI World Index, which may focus its exposure in one or more countries or regions, from time to time the Fund itself may focus its investments in a particular country or geographic region. To the extent that it focuses its investments in a particular country or geographic region, the Fund may be more susceptible to economic, political, regulatory or other events or conditions affecting issuers and countries within that country or geographic region. As a result, the Fund may be subject to greater price volatility and risk of loss than a fund holding more geographically diverse investments.

Preferred Stock Risk – Preferred stocks in which the Fund may invest are sensitive to interest rate changes, and are also subject to equity risk, which is the risk that stock prices will fall over short or extended periods of time. The rights of preferred stocks on the distribution of a company’s assets in the event of a liquidation are generally subordinate to the rights associated with a company’s debt securities.

Depositary Receipts Risk – Investments in depositary receipts may be less liquid and more volatile than the underlying securities in their primary trading market. If a depositary receipt is denominated in a different currency than its underlying securities, the Fund will be subject to the currency risk of both the investment in the depositary receipt and the underlying security. Holders of depositary receipts may have limited or no rights to take action with respect to the underlying securities or to compel the issuer of the receipts to take action. The prices of depositary receipts may differ from the prices of securities upon which they are based.

Management Risk – The success of the Fund’s strategy is dependent on the Adviser’s ability and its stock selection process to correctly identify the Fund’s investments. The portfolio securities selected by the Adviser may decline in value or not increase in value when the stock market in general is rising, in which case the Fund could experience losses regardless of the overall performance of the U.S. equity market.

Quantitative Investing Risk – Funds that are managed according to a quantitative model can perform differently from the market as a whole based on the factors used in the model, the weight placed on each factor and changes from the factors’ historical trends. Due to the significant role technology plays in a quantitative model, use of a quantitative model carries the risk of potential issues with the design, coding, implementation or maintenance of the computer programs, data and/or other technology used in the quantitative model. These issues could negatively impact investment returns.

Liquidity Risk – The risk that certain securities may be difficult or impossible to sell at the time and the price that the Fund would like. The Fund may have to lower the price of the security, sell other securities instead or forego an investment opportunity, any of which could have a negative effect on Fund management or performance.

ETF Risks — The Fund is an exchange-traded fund (“ETF”) and, as a result of this structure, it is exposed to the following risks:

Trading Risk — Shares of the Fund may trade on NYSE Arca, Inc. (the “Exchange”) above or below their NAV. The NAV of shares of the Fund will fluctuate with changes in the market value of the Fund’s holdings. The market prices of the Fund’s shares will fluctuate continuously throughout trading hours based on market supply and demand and may deviate significantly from the value of the Fund’s holdings, particularly in times of market stress, with the result that investors may pay more or receive less than the underlying value of the Fund shares bought or sold. In addition, although the Fund’s shares are currently listed on the Exchange, there can be no assurance that an active trading market for shares will develop or be maintained. Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in shares of the Fund inadvisable. In stressed market conditions, the market for the Fund’s shares may become less liquid in response to deteriorating liquidity in the markets for the Fund’s underlying portfolio holdings.

Cash Transactions Risk — Like other ETFs, the Fund sells and redeems its shares only in large blocks called Creation Units and only to “Authorized Participants.” Unlike many other ETFs, however, the Fund expects to effect its creations and redemptions at least partially for cash, rather than in-kind securities. Thus, an investment in the Fund may be less tax-efficient than an investment in other ETFs as the Fund may recognize a capital gain that it could have avoided by making redemptions in-kind. As a result, the Fund may pay out higher capital gains distributions than ETFs that redeem in-kind. Further, paying redemption proceeds at least partially in cash rather than through in-kind delivery of portfolio securities may require the Fund to dispose of or sell portfolio investments to obtain the cash needed to distribute redemption proceeds at an inopportune time.

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

Investments in Investment Companies Risk – When the Fund invests in an investment company, including ETFs, in addition to directly bearing the expenses associated with its own operations, it will bear a pro rata portion of the investment company’s expenses. Further, while the risks of owning shares of an investment company generally reflect the risks of owning the underlying investments of the investment company, the Fund may be subject to additional or different risks than if the Fund had invested directly in the underlying investments. For example, the lack of liquidity in an ETF could result in its share price being more volatile than that of the underlying portfolio securities.

New Fund Risk – Because the Fund is new, investors in the Fund bear the risk that the Fund may not be successful in implementing its investment strategy, may not employ a successful investment strategy, or may fail to attract sufficient assets under management to realize economies of scale, any of which could result in the Fund being liquidated at any time without shareholder approval and at a time that may not be favorable for all shareholders. Such liquidation could have negative tax consequences for shareholders and will cause shareholders to incur expenses of liquidation.

Valuation Risk — The risk that a security may be difficult to value. The Fund may value certain securities at a price higher than the price at which they can be sold.

Active Management Risk – The Fund is subject to the risk that the Adviser’s judgments about the attractiveness, value, or potential appreciation of the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the Fund fail to produce the intended results, the Fund could underperform in comparison to other funds with similar objectives and investment strategies.

Large Purchase and Redemption Risk – Large purchases or redemptions of the Fund’s shares may force the Fund to purchase or sell securities at times when it would not otherwise do so, and may cause the Fund’s portfolio turnover rate and transaction costs to rise, which may negatively affect the Fund’s performance and have adverse tax consequences for Fund shareholders.

Portfolio Turnover Risk – Due to its investment strategy, the Fund may buy and sell securities frequently. This may result in higher transaction costs and additional capital gains tax liabilities, which may affect the Fund’s performance.
