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 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, except that this Example reflects the fee waiver/expense reimbursement arrangement for each share class through April 30, 2023. Although your actual costs may be higher or lower, based on these assumptions, your costs would be:

Risk Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, at least 80% of the Fund’s net assets (plus the amount of any borrowings for investment purposes) are invested in securities of small capitalization companies. The Fund considers a company to be a small capitalization company if it has a market capitalization, at the time of investment, within the range of the market capitalizations of the companies in the Russell 2000^® Index. The capitalization range of that index is subject to change over time due to market activity or changes in the composition of the index. As of February 28, 2022, the market capitalizations of the companies in the Russell 2000 Index ranged from $18.6 million to $12 billion.

The Fund’s investment sub-advisor, Bahl & Gaynor Inc., d/b/a Bahl & Gaynor Investment Counsel (“Bahl & Gaynor”) pursues its small cap growth strategy by focusing on high-quality dividend-paying stocks. Quantitative tools are initially used for screening purposes, but Bahl & Gaynor’s investment process is primarily driven by fundamental, bottom-up, company-focused processes. The investment process begins by quantitatively screening the stock universe to identify companies with perceived competitive advantages by evaluating their historical revenue growth, earnings growth, long-term debt/capital, dividend history and cash flows. Bahl & Gaynor conducts extensive fundamental research on potential portfolio companies to determine which stock(s) provide the best risk/reward opportunities for inclusion in the portfolio. Bahl & Gaynor typically will sell an investment if the company’s fundamentals have changed or the company’s market capitalization (stock market worth) moves outside of the small cap range.

Although the Fund seeks investments across a number of sectors, from time to time, based on portfolio positioning, the Fund may have significant positions in particular sectors, including the Industrials sector. However, as the sector composition of the Fund’s portfolio changes over time, the Fund’s exposure to the Industrials sector may be lower at a future date, and the Fund’s exposure to other market sectors may be higher.

The Fund’s equity investments may include common stocks, depositary receipts that may include American Depositary Receipts (“ADRs”), master limited partnerships (“MLPs”), U.S. dollar-denominated foreign stocks traded on U.S. exchanges, and real estate investments trusts (“REITs”). The Fund may invest in stocks considered to be value stocks, which generally trade at prices that are lower than their perceived full value.

The Fund may invest cash balances in other investment companies, including government money market funds, and may purchase and sell futures contracts, including equity index futures contracts, to gain market exposure on cash balances in anticipation of liquidity needs. The Fund may seek to earn additional income by lending its securities to certain qualified broker-dealers and institutions.

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund and its service providers as well as the ability of shareholders to transact with the Fund. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Dividend Risk
An issuer of stock held by the Fund may choose not to declare a dividend or the dividend rate might not remain at current levels or increase over time. Dividend paying stocks might not experience the same level of earnings growth or capital appreciation as non-dividend paying stocks. Securities that pay dividends may be sensitive to changes in interest rates and, as interest rates rise or fall, the prices of such securities may fall.

Equity Investments Risk
Equity securities are subject to investment risk and market risk. The Fund may invest in the following equity securities, which may expose the Fund to the following additional risks:

■

Common Stock Risk. The value of a company’s common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.

■

Depositary Receipts and U.S. Dollar-Denominated Foreign Stocks Traded on U.S. Exchanges Risk. Depositary receipts and U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular depositary receipt or foreign stock, less liquidity, more volatility, less government regulation and supervision and delays in transaction settlement.

■

Master Limited Partnerships (“MLPs”) Risk. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to change their portfolios promptly in response to changes in economic or other conditions. MLPs may have limited financial resources, their securities may trade infrequently and in limited volume, they may be difficult to value, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies. Holders of units in MLPs have more limited rights to vote on matters affecting the partnership and may be required to sell their common units at an undesirable time or price. The Fund’s investments in MLPs will be limited to no more than 25% of its assets in order for the Fund to meet the requirements necessary to qualify as a “regulated investment company” under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”).

■

Real Estate Investment Trusts (“REITs”) Risk. Investments in REITs are subject to the risks associated with investing in the real estate industry, including, among other risks: adverse developments affecting the real estate industry; declines in real property values; changes in interest rates; defaults by mortgagors or other borrowers and tenants; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; casualty or condemnation losses; and governmental actions, such as changes to tax laws, zoning regulations or environmental regulations. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Regardless of where a REIT is organized or traded, its performance may be affected significantly by events in the region where its properties are located. Domestic REITs could be adversely affected by failure to qualify for tax-free “pass-through” of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), or to maintain their exemption from registration under the Investment Company Act of 1940, as amended (“Investment Company Act”). REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund’s investment in

REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise. REITs tend to be small- to mid-capitalization securities and, as such, are subject to the risks of investing in small- to mid-capitalization securities.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets. The Fund’s investment in a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country. Global economic and financial markets are becoming increasingly interconnected and conditions (including recent volatility and instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Futures Contracts Risk
Futures contracts are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities underlying those derivatives. There can be no assurance that any strategy used will succeed. There may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes. There also can be no assurance that, at all times, a liquid market will exist for offsetting a futures contract that the Fund has previously bought or sold, and this may result in the inability to close a futures contract when desired. Futures contracts may experience potentially dramatic price changes, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). Equity index futures contracts expose the Fund to volatility in an underlying securities index. Use of derivatives is a highly specialized activity that can involve investment techniques and risks different from, and in some respects greater than, those associated with investing in more traditional investments. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways.

Growth Companies Risk
Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund’s investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company’s growth is incorrect, then the price of the company’s stock may fall or not approach the value placed on it. Growth company stocks may also lack the dividend yield that can cushion stock price declines in market downturns.

Interest Rate Risk
The value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, may decline when interest rates rise. Rising interest rates can reduce companies’ profitability and their ability to pay dividends.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund’s performance. Equity securities generally have greater price volatility than fixed income securities, although under certain market conditions fixed income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last decade, but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. Changes in value may be temporary or may last for extended periods.

Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations.

■

Recent Market Events Risk. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in late 2019 and has subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted, and may continue to result, in significant disruptions to business operations, widespread business closures and layoffs, travel restrictions and closed borders, prolonged quarantines and stay-at-home orders, disruption of and delays in healthcare service preparation and delivery, service and event changes, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. The impact of the pandemic has negatively affected and may

continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased.

The Federal Reserve has spent hundreds of billions of dollars to keep credit flowing through the economy. However, the Federal Reserve recently began to reduce its interventions as the economy improved and inflation accelerated. Concerns about the markets’ dependence on the Federal Reserve’s provision of liquidity have grown as a result. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons.

Interest rates have been unusually low in recent years in the U.S. and abroad, and central banks reduced rates further in an effort to combat the economic effects of the COVID-19 pandemic. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes. The U.S. Federal Reserve has started to raise interest rates, in part to address an increase in the annual inflation rate in the U.S. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

Slowing global economic growth, risks associated with the United Kingdom’s departure from the European Union on December 31, 2020, commonly referred to as “Brexit,” and a trade agreement between the United Kingdom and the European Union, the risks associated with ongoing trade negotiations with China, the possibility of changes to some international trade agreements, tensions, war, or open conflict between nations, such as between Russia and Ukraine, or political or economic dysfunction within some nations that are major producers of oil could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. Russia’s military invasion of Ukraine beginning in February 2022, the responses and sanctions by the United States and other countries, and the potential for wider conflict have had, and could continue to have, severe adverse effects on regional and global economies and could further increase volatility and uncertainty in the financial markets.

Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

Other Investment Companies Risk
To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity securities, fixed income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject. The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

■	Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs. Heavy redemptions could hurt the Fund’s performance.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. As the Fund’s portfolio changes over time, the Fund’s exposure to a particular sector may become higher or lower.

■

Industrials Sector Risk. The industrials sector includes companies engaged in the construction and engineering industry, machinery, energy, transportation, professional services, aerospace and defense industries. Companies in the industrials sector may be adversely affected by changes in government regulation, world events and economic conditions. In addition, companies in the industrials sector may be adversely affected by environmental damage, product and environmental liability claims, changes in commodity prices and exchange rates, changes in the supply and demand for products and services, and product obsolescence, among other factors.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: (i) the securities in which the Fund reinvests cash collateral may decrease in value, causing the Fund to incur a loss, or may not perform sufficiently to cover the Fund’s payment to the borrower of a pre-negotiated fee or “rebate” for the use of that cash collateral in connection with the loan; (ii) non-cash collateral may decline in value, resulting in the Fund becoming under-secured; (iii) delays may occur in the recovery of loaned securities from borrowers, which could result in the Fund being unable to vote proxies or settle transactions or cause the Fund to incur increased costs; and (iv) if the borrower becomes subject to insolvency or similar proceedings, the Fund could incur delays in its ability to enforce its rights in its collateral.

Securities Selection Risk
Securities selected for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to its benchmark index(es), or other funds with similar investment objectives or strategies.

Small-Capitalization Companies Risk
Investing in the securities of small-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger-capitalization and more established companies. Since small-capitalization companies may have narrower commercial markets, and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity and they can be particularly sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may decline. Although value stocks tend to be inexpensive relative to their earnings, they can continue to be inexpensive for long periods of time. The Fund’s investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund’s investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

Risk Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests in a diversified portfolio of large capitalization companies that are listed on the New York Stock Exchange, NYSE American, or Nasdaq. Under normal circumstances, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in stocks from among those in the large-cap growth category at the time of purchase. For purposes of the Fund’s investments, “large-cap stocks” are stocks of companies whose market capitalization falls within the range of the Russell 1000^® Index at the time of investment. The Russell 1000 Index is an unmanaged, market value weighted index, which measures performance of approximately 1,000 of the largest companies in the U.S. equity market. The Russell 1000 Index is reconstituted from time to time. The market capitalization range for the Russell 1000 Index was $477.3 million to $2.7 trillion as of February 28, 2022.

Growth stocks are those that the Fund’s sub-advisor, Bridgeway Capital Management, LLC (“Bridgeway Capital”), believes have above average prospects for economic growth. Generally, these are stocks represented in the Russell 1000^® Growth Index, but may also include stocks of other companies with similar “growth” characteristics whose market capitalizations are within the range of the Russell 1000 Index. In order to diversify the Fund’s investments, the Fund’s sub-advisor allocates up to 10% of the Fund’s assets to value stocks. Generally these are stocks represented in the Russell 1000 Value Index, but may also include stocks of other companies with similar “value” characteristics whose market capitalizations are within the range of the Russell 1000 Index. The Russell 1000 Growth Index includes those Russell 1000 companies with higher price-to-book ratios and higher forecasted growth values. The Russell 1000 Value Index includes those Russell 1000 companies with lower price-to-book ratios and lower forecasted growth values.

The Fund’s investments may include common stocks, real estate investment trusts (“REITs”), and dollar-denominated foreign stocks traded on U.S. exchanges (collectively referred to as “stocks”). The Fund also may invest in stocks of mid-capitalization companies.

Bridgeway Capital uses a proprietary model-driven quantitative approach to select stocks within the large-cap growth category. Bridgeway Capital will not necessarily sell a stock if it “migrates” outside the market capitalization range of the Russell 1000 Index after purchase. As a result, due to such “migration” or other market movements, the Fund may have less than 80% of its assets in large-cap stocks at any point in time. Based on statistically driven rules, securities are sold when the reasons for selecting the stock are no longer valid or when necessary to maintain the risk profile of the overall Fund.

Bridgeway Capital’s investment process incorporates material environmental, social, and/or governance (“ESG”) information as a consideration in the assessment of all potential portfolio securities. Bridgeway Capital uses ESG research and/or ratings information provided by third parties in performing this analysis and considering ESG risks. As with any consideration used in assessing portfolio securities, Bridgeway Capital may, at times, utilize ESG information to increase the weighting of an issuer with a good ESG record and/or decrease the weighting of an issuer with a poor ESG record. Additionally, Bridgeway Capital generally prohibits investments in companies that, based on Bridgeway Capital’s judgment, are involved more than minimally in: (1) Sudan operations, (2) tobacco, or (3) adult entertainment.

Although the Fund seeks investments across a number of sectors, from time to time, based on portfolio positioning to reflect its benchmark index, the Fund may have significant positions in particular sectors, including the Information Technology sector. However, as the sector composition of the Fund’s portfolio changes over time, the Fund’s exposure to the Information Technology sector may be lower at a future date, and the Fund’s exposure to other market sectors may be higher.

While the Fund is actively managed for long-term total return, Bridgeway Capital seeks to minimize capital gain distributions as part of a tax management strategy. The successful application of this method is intended to result in a more tax-efficient fund than would otherwise be the case, but this method will not be solely determinative in any investment decision made by Bridgeway Capital.

The Fund may also invest cash balances in other investment companies, including government money market funds, and may purchase and sell futures contracts, including equity index futures contracts, to gain market exposure on cash balances or reduce market exposure in anticipation of liquidity needs. The Fund may seek to earn additional income by lending its securities to certain qualified broker-dealers and institutions.

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears.

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund and its service providers as well as the ability of shareholders to transact with the Fund. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Environmental, Social, and/or Governance Investing Risk
The use of environmental, social, and/or governance (“ESG”) considerations by the sub-advisor may cause the Fund to make different investments than funds that have a similar investment style but do not incorporate such considerations in their strategy. As with the use of any investment considerations involved in investment decisions, there is no guarantee that the use of any ESG investment considerations will result in the selection of issuers that will outperform other issuers or help reduce risk in the Fund. The Fund may choose not to, or may not be able to, take advantage of certain investment opportunities due to these considerations, which may adversely affect investment performance. The Fund may underperform funds that do not incorporate these considerations.

Equity Investments Risk
Equity securities are subject to investment risk and market risk. The Fund may invest in the following equity securities, which may expose the Fund to the following additional risks:

■

Common Stock Risk. The value of a company’s common stock may fall as a result of factors affecting the company, companies in the same industry or sector, or the financial markets overall. Common stock generally is subordinate to preferred stock upon the liquidation or bankruptcy of the issuing company.

■

Real Estate Investment Trusts (“REITs”) Risk. Investments in REITs are subject to the risks associated with investing in the real estate industry, including, among other risks: adverse developments affecting the real estate industry; declines in real property values; changes in interest rates; defaults by mortgagors or other borrowers and tenants; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; casualty or condemnation losses; and governmental actions, such as changes to tax laws, zoning regulations or environmental regulations. REITs also are dependent upon the skills of their managers and are subject to heavy cash flow dependency or self-liquidation. Regardless of where a REIT is organized or traded, its performance may be affected significantly by events in the region where its properties are located. Domestic REITs could be adversely affected by failure to qualify for tax-free “pass-through” of distributed net income and net realized gains under the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), or to maintain their exemption from registration under the Investment Company Act of 1940, as amended (“Investment Company Act”). REITs typically incur fees that are separate from those incurred by the Fund. Accordingly, the Fund’s investment in REITs will result in the layering of expenses such that shareholders will indirectly bear a proportionate share of the REITs’ operating expenses, in addition to paying Fund expenses. The value of REIT common stock may decline when interest rates rise. REITs tend to be small- to mid-capitalization securities and, as such, are subject to the risks of investing in small- to mid-capitalization securities.

■

U.S. Dollar-Denominated Foreign Stocks Traded on U.S. Exchanges Risk. U.S. dollar-denominated foreign stocks traded on U.S. exchanges are subject to certain of the risks associated with investing directly in foreign securities, including, but not limited to, currency exchange rate fluctuations, political and financial instability in the home country of a particular foreign stock, less liquidity, more volatility, less government regulation and supervision and delays in transaction settlement.

Foreign Investing Risk
Non-U.S. investments carry potential risks not associated with U.S. investments. Such risks include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) increased volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets. The Fund’s investment in a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country. Global economic and financial markets are becoming increasingly interconnected and conditions (including recent volatility and instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Futures Contracts Risk
Futures contracts are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities underlying those derivatives. There can be no assurance that any strategy used will succeed. There may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes. There also can be no assurance that, at all times, a liquid market will exist for offsetting a futures contract that the Fund has previously bought or sold, and this may result in the inability to close a futures contract when desired. Futures contracts may experience potentially dramatic price changes, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). Equity index futures contracts expose the Fund to volatility in an underlying securities index. Use of derivatives is a highly specialized activity that can involve investment techniques and risks different from, and in some respects greater than, those associated with investing in more traditional investments. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways.

Growth Companies Risk
Growth companies are expected to increase their earnings at a certain rate. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. The Fund’s investments in growth companies may be more sensitive to company earnings and more volatile than the market in general primarily because their stock prices are based heavily on future expectations. If an assessment of the prospects for a company’s growth is incorrect, then the price of the company’s stock may fall or not approach the value placed on it. Growth company stocks may also lack the dividend yield that can cushion stock price declines in market downturns.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Issuer Risk
The value of, and/or the return generated by, a security may decline for a number of reasons that directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or services, as well as the historical and prospective earnings of the issuer and the value of its assets.

Large-Capitalization Companies Risk
The securities of large market capitalization companies may underperform other segments of the market because such companies may be less responsive to competitive challenges and opportunities and, at times, such companies may be out of favor with investors. Many larger-capitalization companies also may be unable to attain the high growth rates of successful smaller companies, especially during periods of economic expansion.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund’s performance. Equity securities generally have greater price volatility than fixed income securities, although under certain market conditions fixed income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last decade, but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters and related

events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. Changes in value may be temporary or may last for extended periods.

Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations.

■

Recent Market Events Risk. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in late 2019 and has subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted, and may continue to result, in significant disruptions to business operations, widespread business closures and layoffs, travel restrictions and closed borders, prolonged quarantines and stay-at-home orders, disruption of and delays in healthcare service preparation and delivery, service and event changes, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased.

The Federal Reserve has spent hundreds of billions of dollars to keep credit flowing through the economy. However, the Federal Reserve recently began to reduce its interventions as the economy improved and inflation accelerated. Concerns about the markets’ dependence on the Federal Reserve’s provision of liquidity have grown as a result. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons.

Interest rates have been unusually low in recent years in the U.S. and abroad, and central banks reduced rates further in an effort to combat the economic effects of the COVID-19 pandemic. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes. The U.S. Federal Reserve has started to raise interest rates, in part to address an increase in the annual inflation rate in the U.S. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

Slowing global economic growth, risks associated with the United Kingdom’s departure from the European Union on December 31, 2020, commonly referred to as “Brexit,” and a trade agreement between the United Kingdom and the European Union, the risks associated with ongoing trade negotiations with China, the possibility of changes to some international trade agreements, tensions, war, or open conflict between nations, such as between Russia and Ukraine, or political or economic dysfunction within some nations that are major producers of oil could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. Russia’s military invasion of Ukraine beginning in February 2022, the responses and sanctions by the United States and other countries, and the potential for wider conflict have had, and could continue to have, severe adverse effects on regional and global economies and could further increase volatility and uncertainty in the financial markets.

Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

Mid-Capitalization Companies Risk
Investing in the securities of mid-capitalization companies involves greater risk and the possibility of greater price volatility, which at times can be rapid and unpredictable, than investing in larger-capitalization and more established companies. Since mid-capitalization companies may have narrower commercial markets and more limited operating history, product lines, and managerial and financial resources than larger, more established companies, the securities of these companies may lack sufficient market liquidity, and they can be particularly sensitive to changes in overall economic conditions, interest rates, borrowing costs and earnings.

Model and Data/Programming Error Risk
The success of the sub-advisor’s investment strategy depends largely on the effectiveness of its quantitative research models and investment programs. Models (including quantitative models), data, and investment programs are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks and programs may not react as expected to market events, resulting in losses for the Fund. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. There is no assurance that the models are complete or accurate, or representative of future market cycles, nor will they always be beneficial to the Fund if they are accurate. Additionally, programs may become outdated or experience malfunctions which may not be identified by the sub-advisor and therefore may also result in losses to the Fund. These models and programs may negatively affect Fund performance for various other reasons, including human judgment, inaccuracy of historical data and non-quantitative factors (such as market or trading system dysfunctions, investor fear or overreaction).

Other Investment Companies Risk
To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity

securities, fixed income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject. The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

■	Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.

Quantitative Strategy Risk
The success of the Fund’s investment strategy may depend in part on the effectiveness of the sub-advisor’s quantitative tools for screening securities. These strategies may incorporate factors that are not predictive of a security’s value. The quantitative tools may not react as expected to market events, resulting in losses for the Fund. Additionally, a previously successful strategy may become outdated or inaccurate, which may not be identified by the sub-advisor and therefore may also result in losses.

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs. Heavy redemptions could hurt the Fund’s performance.

Sector Risk
When the Fund focuses its investments in certain sectors of the economy, its performance may be driven largely by sector performance and could fluctuate more widely than if the Fund were invested more evenly across sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. As the Fund’s portfolio changes over time, the Fund’s exposure to a particular sector may become higher or lower.

■

Information Technology Sector Risk. The information technology sector includes companies engaged in internet software and services, technology hardware and storage peripherals, electronic equipment and components, and semiconductors and semiconductor equipment. Information technology companies face intense competition, both domestically and internationally, which may have an adverse effect on profit margins. Information technology companies may have limited product lines, markets, financial resources or personnel. The products of information technology companies may face rapid product obsolescence due to technological developments and frequent new product introduction, unpredictable changes in growth rates and competition for the services of qualified personnel. Failure to introduce new products, develop and maintain a loyal customer base or achieve general market acceptance for their products could have a material adverse effect on a company’s business. Companies in the information technology sector are heavily dependent on intellectual property and the loss of patent, copyright or trademark protections may adversely affect the profitability of these companies. The market prices of information technology-related securities tend to exhibit a greater degree of market risk and sharp price fluctuations than other types of securities. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices.

Securities Lending Risk
To the extent the Fund lends its securities, it may be subject to the following risks: (i) the securities in which the Fund reinvests cash collateral may decrease in value, causing the Fund to incur a loss, or may not perform sufficiently to cover the Fund’s payment to the borrower of a pre-negotiated fee or “rebate” for the use of that cash collateral in connection with the loan; (ii) non-cash collateral may decline in value, resulting in the Fund becoming under-secured; (iii) delays may occur in the recovery of loaned securities from borrowers, which could result in the Fund being unable to vote proxies or settle transactions or cause the Fund to incur increased costs; and (iv) if the borrower becomes subject to insolvency or similar proceedings, the Fund could incur delays in its ability to enforce its rights in its collateral.

Securities Selection Risk
Securities selected for the Fund may not perform to expectations. This could result in the Fund’s underperformance compared to its benchmark index(es), or other funds with similar investment objectives or strategies.

Tax Management Risk
The Fund’s tax management strategies may result in it forgoing performance in favor of tax benefits that may not materialize, or may result in pre-tax performance that is lower than that of funds that do not use tax-management strategies.

Value Stocks Risk
Value stocks are subject to the risk that their intrinsic or full value may never be realized by the market, that a stock judged to be undervalued may be appropriately priced, or that their prices may decline. Although value stocks tend to be inexpensive relative to their earnings, they can continue to be inexpensive for long periods of time. The Fund’s investments in value stocks seek to limit potential downside price risk over time; however, value stock prices still may decline substantially. In addition, the Fund may produce more modest gains as a trade-off for this potentially lower risk. The Fund’s investment in value stocks could cause the Fund to underperform funds that use a growth or non-value approach to investing or have a broader investment style.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

The bar chart and table below provide an indication of risk by showing changes in the Fund’s performance over time. The bar chart shows how the Fund’s performance has varied from year to year. The table shows how the Fund’s average annual total returns compare compares to a broad-based market index, which is the Fund’s benchmark index and was the benchmark index of the Fund’s predecessor, for the periods indicated.

On February 5, 2016, the Fund acquired all the assets and assumed all the liabilities of the Fund’s predecessor. In connection with that reorganization, the R5 Class shares of the Fund adopted the performance history and financial statements of the Fund’s predecessor. In the bar chart and table below, the performance of the Fund’s R5 Class shares for periods prior to February 5, 2016 is the performance of the Fund’s predecessor. In the table below, the performance of the Fund’s A Class, C Class, Y Class, and Investor Class shares for periods prior to February 5, 2016 also represents the returns of the Fund’s predecessor. In the table below, the performance for the R6 Class shares for periods prior to April 30, 2018 represents the returns achieved by the Fund’s predecessor from January 1, 2012 through February 4, 2016 and the performance of the Fund’s R5 Class from February 5, 2016 through April 29, 2018. In each case, the newer share classes would have had similar annual returns to the Fund’s predecessor because the shares of each class represent investments in the same portfolio securities. However, the older share class had different expenses than the newer share classes, which would affect performance. The performance of the newer share classes shown in the table has not been adjusted for differences in operating expenses between those share classes and the shares of the Fund’s predecessor, but the A Class and C Class shares performance has been adjusted for the impact of the maximum applicable sales charge. You may obtain updated performance information on the Fund’s website at www.americanbeaconfunds.com. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Assuming no redemption of shares:

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund’s performance. Portfolio turnover is based on the lesser of long-term purchases or sales divided by the average long-term fair value during a period. The Fund did not invest in any long-term securities during the most recent fiscal year. As a result, the Fund’s portfolio turnover rate for the Fund’s most recent fiscal year is not provided.

Risk Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by implementing a quantitative trading strategy and systematic investment process designed to capitalize on price trends (up and/or down) in a broad range of global markets including stock indices, bonds and bond futures, currency and currency futures, and interest rates by utilizing derivative instruments. As the owner of a “long” position in a derivative instrument, the Fund may benefit from an increase in the price of the underlying investment and, as the owner of a “short” position, the Fund may benefit from a decrease in the price of the underlying investment.

The Fund invests primarily in derivatives, including futures contracts (such as equity index futures, interest rate futures, treasury futures, and non-U.S. currency futures), and forward contracts, such as foreign currency forward contracts and non-deliverable forwards (“NDFs”). The Fund also may invest in swaps, which may include commodities swaps, credit default swaps, currency swaps, equity swaps, interest rate swaps and total return swaps, and other types of derivative instruments linked to stock indices, currencies, bonds, interest rates and commodity instruments. The Fund expects that, under normal market conditions, the notional value of its derivatives exposure generally will exceed that of its net assets. In connection with the Fund’s use of derivatives, which may be used for hedging purposes or for exposure to a market, the Fund may hold significant amounts of U.S. government securities, including U.S. Treasury securities and other foreign developed market sovereign short-term bonds issued by countries such as France, Germany, Japan and other developed countries, or short-term investments, including government money market funds, cash and time deposits in order to meet collateral and applicable asset coverage requirements under the Investment Company Act of 1940, as amended (the “Investment Company Act”). Additionally, the Fund may invest in bonds and zero coupon securities, U.S. and non-U.S. currencies and securities denominated in non-U.S. currencies. The Fund’s investments are generally made without restriction as to issuer market capitalization, country, currency, maturity or credit rating. The Fund may invest in issuers in the U.S. and foreign developed and emerging markets.

The Fund seeks to gain exposure to the commodity futures markets by investing up to 25% of its total assets in a wholly-owned subsidiary, which is organized under the laws of the Cayman Islands (the “Subsidiary”). Generally, the Subsidiary invests primarily in commodity futures, but it may also invest in financial futures and forwards and swap contracts, fixed income securities, pooled investment vehicles, including open-end investment companies, and other investments intended to serve as margin or collateral for the Subsidiary’s derivative positions. The Fund invests in the Subsidiary in order to gain exposure to the commodities markets within the limitations of the federal tax law, rules and regulations that apply to “regulated investment companies.” Unlike the Fund, the Subsidiary may invest without limitation in commodity-linked derivatives, however, the Subsidiary and the Fund, in the aggregate, comply with applicable Investment Company Act asset coverage requirements with respect to their total investments in commodity-linked derivatives. In addition, the Fund and the Subsidiary comply with the same fundamental investment restrictions on an aggregate basis and the Subsidiary follows the same compliance policies and procedures as the Fund to the extent those restrictions, policies and procedures are applicable to the investment activities of the Subsidiary. Unlike the Fund, the Subsidiary does not, and will not, seek to qualify as a “regulated investment company” under Subchapter M of Chapter 1 of Subtitle A of the Internal Revenue Code of 1986, as amended (“Subchapter M”). The Fund is the sole shareholder of the Subsidiary and does not expect shares of the Subsidiary to be offered or sold to other investors.

The sub-advisor employs computerized processes to identify investment opportunities across a wide range of markets around the world. Investment decisions are executed via the sub-advisor’s proprietary execution strategy. The investment decision process is quantitative and primarily directional in nature, meaning that investment decisions are driven by mathematical models based on market trends and other historical relationships. It is underpinned by risk control, ongoing research, diversification and the quest for efficiency. The Fund’s holdings may be frequently adjusted to reflect the sub-advisor’s assessment of changing risks, which could result in high portfolio turnover.

The cornerstone of the sub-advisor’s investment philosophy is that the financial markets exhibit trends and other inefficiencies. Trends are a manifestation of serial correlation in financial markets — the phenomenon whereby past price movements influence price behavior. Although price trends vary in their intensity, duration and frequency they typically recur across sectors and markets. Trends are an attractive focus for active trading styles applied across a range of global markets. In implementing its investment program, the Fund may hold significant cash positions from time to time. Accordingly, the sub-advisor will make investment decisions for cash management purposes. Such arrangements may include investing in cash equivalents.

The Fund is non-diversified, which means that it is not limited to a percentage of assets that it may invest in any one issuer.

rr_RiskNarrativeTextBlock

There is no assurance that the Fund will achieve its investment objective and you could lose part or all of your investment in the Fund. The Fund is not designed for investors who need an assured level of current income and is intended to be a long-term investment. The Fund is not a complete investment program and may not be appropriate for all investors. Investors should carefully consider their own investment goals and risk tolerance before investing in the Fund. The principal risks of investing in the Fund listed below are presented in alphabetical order and not in order of importance or potential exposure. Among other matters, this presentation is intended to facilitate your ability to find particular risks and compare them with the risks of other funds. Each risk summarized below is considered a “principal risk” of investing in the Fund, regardless of the order in which it appears. The principal risks of the Subsidiary are listed in this section of the Prospectus as principal risks of the Fund.

Allocation Risk
The allocations among strategies, asset classes and market exposures may be less than optimal and may adversely affect the Fund’s performance. There can be no assurance, particularly during periods of market disruption and stress, that judgments about allocations will be correct. The Fund’s allocations may be invested in strategies, asset classes and market exposures during a period when such strategies, asset classes and market exposures underperform.

Asset Selection Risk
Assets selected for the Fund may not perform to expectations. The investment models used to manage the Fund may rely in part on data derived from third parties and may not perform as intended. This could result in the Fund’s underperformance compared to other funds with similar investment objectives.

Commodities Risk
The Fund’s investments in commodity-linked derivative instruments 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, commodity price volatility, changes in interest rates, or factors affecting a particular industry or commodity, such as changes in supply and demand, resource availability, speculation in the commodities markets, drought, floods, weather, livestock disease, pandemics, embargoes, tariffs, war, acts of terrorism and international economic, political and regulatory developments. The Fund may invest significantly in a particular sector of the commodities market (such as oil, metal or

agricultural products). As a result, the Fund may be more susceptible to risks associated with those sectors. No active trading market may exist for certain commodities investments. The Fund’s investments in commodity-related instruments may lead to losses in excess of the Fund’s investment in such products, as some commodity-linked derivatives can have the potential for unlimited losses. Such losses can significantly and adversely affect the net asset value (“NAV”) per share of the Fund and, consequently, a shareholder’s interest in the Fund. Because the Fund’s performance is linked to the performance of potentially volatile commodities, investors should be willing to assume the risks of significant fluctuations in the value of the Fund’s shares.

Counterparty Risk
The Fund is subject to the risk that a party or participant to a transaction, such as a broker or a derivative counterparty, will be unwilling or unable to satisfy its obligation to make timely principal, interest or settlement payments or to otherwise honor its obligations to the Fund.

Credit Risk
The Fund is subject to the risk that the issuer, guarantor or insurer of an obligation, or the counterparty to a transaction may fail, or become less able or unwilling, to make timely payment of interest or principal or otherwise honor its obligations or default completely. Changes in the actual or perceived creditworthiness of an issuer, or a downgrade or default affecting any of the Fund’s securities, could affect the Fund’s performance. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

Crowding/Convergence Risk
There is significant competition among quantitatively-focused managers, and the ability of the sub-advisor to outperform other funds is dependent on its ability to employ models that are simultaneously profitable and differentiated from those employed by other managers. To the extent that the sub-advisor is not able to develop sufficiently differentiated models, the Fund’s investment objective may not be met, irrespective of whether the models are profitable in an absolute sense.

Currency Risk
The Fund may have exposure to foreign currencies by using various instruments. Foreign currencies may fluctuate significantly over short periods of time, may be affected unpredictably by intervention, or the failure to intervene, of the U.S. or foreign governments or central banks, and may be affected by currency controls or political developments in the U.S. or abroad. Foreign currencies may also decline in value relative to the U.S. dollar and other currencies and thereby affect the Fund’s investments.

Cybersecurity and Operational Risk
Operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents may negatively impact the Fund and its service providers as well as the ability of shareholders to transact with the Fund. Cybersecurity incidents may allow an unauthorized party to gain access to Fund assets, shareholder data, or proprietary information, or cause the Fund or its service providers, as well as securities trading venues and their service providers, to suffer data corruption or lose operational functionality. It is not possible for the Fund or its service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Derivatives Risk
Derivatives may involve significant risk. The use of derivative instruments may expose the Fund to additional risks that it would not be subject to if it invested directly in the securities or other instruments underlying those derivatives, including the high degree of leverage often embedded in such instruments, and potential material and prolonged deviations between the theoretical value and realizable value of a derivative. Some derivatives have the potential for unlimited loss, regardless of the size of the Fund’s initial investment. The use of derivatives may also increase any adverse effects resulting from the underperformance of strategies, asset classes and market exposures to which the Fund has allocated its assets. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Certain derivatives may be difficult to value, and valuation may be more difficult in times of market turmoil. Derivatives may also be more volatile than other types of investments. The Fund may buy or sell derivatives not traded on an exchange, which may be subject to heightened liquidity and valuation risk. Derivative investments can increase portfolio turnover and transaction costs. Derivatives also are subject to counterparty risk and credit risk. As a result, the Fund may not recover its investment or may only obtain a limited recovery, and any recovery may be delayed. Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Ongoing changes to the regulation of the derivatives markets and potential changes in the regulation of funds using derivative instruments could limit the Fund’s ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance. In addition, the Fund’s investments in derivatives are subject to the following risks:

■

Foreign Currency Forward Contracts Risk. Foreign currency forward contracts, including non-deliverable forwards (“NDFs”), are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of foreign currency at an agreed date or to buy or sell a specific currency at a future date at a price set at the time of the contract and include the risks associated with fluctuations in currency. There are no limitations on daily price movements of forward contracts. There can be no assurance that any strategy used will succeed. Not all forward contracts, including NDFs, require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. The use of foreign currency forward contracts may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities or currencies underlying the foreign currency forward contract.

■

Foreign Currency Futures Contracts Risk. Foreign currency futures contracts are derivative instruments pursuant to a contract where the parties agree to pay a fixed price for an agreed amount of foreign currency at an agreed date or to buy or sell a specific currency at a future date at a price set at the time of the contract. Foreign currency futures contracts are similar to foreign currency forward contracts, except that they are traded on exchanges (and may have margin requirements) and are standardized as to contract size and delivery date. The Fund may use foreign currency futures contracts for the same purposes as foreign currency forward contracts, subject to Commodity Futures Trading Commission (“CFTC”) regulations. The use of foreign currency futures contracts may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities or currencies underlying the foreign currency futures contract. Foreign currency futures transactions and currency futures contracts include risks associated with fluctuations in currency, and other risks inherent in trading derivatives. There can be no assurance that a liquid secondary market will be available to the Fund for the appropriate type of contract at any particular time. Consequently, the Fund may experience losses if it is unable to timely exit its position due to an illiquid secondary market.

■

Forward Contracts Risk. Forward contracts, including non-deliverable forwards (“NDFs”), are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date or to buy or sell a specific currency at a future date at

a price set at the time of the contract. There are no limitations on daily price movements of forward contracts. There can be no assurance that any strategy used will succeed. Not all forward contracts, including NDFs, require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. The use of forward contracts may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities or currencies underlying the forward contract.

■

Futures Contracts Risk. Futures contracts are derivative instruments pursuant to a contract where the parties agree to a fixed price for an agreed amount of securities or other underlying assets at an agreed date. The use of such derivative instruments may expose the Fund to additional risks, such as credit risk, liquidity risk, and counterparty risk, that it would not be subject to if it invested directly in the securities underlying those derivatives. There can be no assurance that any strategy used will succeed. There may at times be an imperfect correlation between the movement in the prices of futures contracts and the value of their underlying instruments or indexes. There also can be no assurance that, at all times, a liquid market will exist for offsetting a futures contract that the Fund has previously bought or sold, and this may result in the inability to close a futures contract when desired. Futures contracts may experience potentially dramatic price changes, which will increase the volatility of the Fund and may involve a small investment of cash (the amount of initial and variation margin) relative to the magnitude of the risk assumed (the potential increase or decrease in the price of the futures contract). Equity index futures contracts expose the Fund to volatility in an underlying securities index. Interest rate futures contracts expose the Fund to price fluctuations resulting from changes in interest rates. The Fund could suffer a loss if interest rates rise after the Fund has purchased an interest rate futures contract or fall after the Fund has sold an interest rate futures contract. Treasury futures contracts expose the Fund to price fluctuations resulting from changes in interest rates and to potential losses if interest rates do not move as expected.

■

Swap Agreements Risk. Swap agreements or “swaps” are transactions in which the Fund and a counterparty agree to pay or receive payments at specified dates based upon or calculated by reference to changes in specified prices or rates or the performance of specified securities, indices or other assets based on a specified amount (the “notional” amount). Swaps can involve greater risks than a direct investment in an underlying asset, because swaps typically include a certain amount of embedded leverage and as such are subject to leverage risk. If swaps are used as a hedging strategy, the Fund is subject to the risk that the hedging strategy may not eliminate the risk that it is intended to offset, due to, among other reasons, the occurrence of unexpected price movements or the non-occurrence of expected price movements. Swaps also may be difficult to value. Swaps may be subject to liquidity risk and counterparty risk, and swaps that are traded over-the-counter are not subject to standardized clearing requirements and may involve greater liquidity and counterparty risks. The Fund may invest in the following types of swaps:

Commodities swaps, which may be subject to commodities risk.

Credit default swaps, which may be subject to credit risk and the risks associated with the purchase and sale of credit protection.

Currency swaps, which may be subject to currency risk and credit risk.

Equity swaps, which may be subject to equity investments risk.

Interest rate swaps, which may be subject to interest rate risk and credit risk.

Total return swaps, which may be subject to credit risk and, if the underlying securities are bonds or other debt obligations, market risk and interest rate risk.

Emerging Markets Risk
When investing in emerging markets, the risks of investing in foreign securities are heightened. Emerging markets are generally smaller, less developed, less liquid and more volatile than the securities markets of the U.S. and other developed markets. There are also risks of: greater political or economic uncertainties; an economy’s dependence on revenues from particular commodities or on international aid or development assistance; currency transfer restrictions; a limited number of potential buyers for such securities resulting in increased volatility and limited liquidity for emerging market securities; trading suspensions and other restrictions on investment; delays and disruptions in securities settlement procedures; and significant limitations on investor rights and recourse. The governments of emerging market countries may also be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. In addition, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing, financial reporting and recordkeeping standards and requirements comparable to those to which U.S. companies are subject.

Foreign Exposure Risk
Exposure to obligations of non-U.S. issuers carries potential risks not associated with investments in obligations of U.S. issuers. Such risks may include, but are not limited to: (1) currency exchange rate fluctuations, (2) political and financial instability, (3) less liquidity, (4) lack of uniform accounting, auditing and financial reporting standards, (5) greater volatility, (6) different government regulation and supervision of foreign stock exchanges, brokers and listed companies, and (7) delays in transaction settlement in some foreign markets. The Fund’s exposure to a foreign issuer may subject the Fund to regulatory, political, currency, security, economic and other risks associated with that country. Global economic and financial markets are becoming increasingly interconnected and conditions (including recent volatility and instability) and events (including natural disasters) in one country, region or financial market may adversely impact issuers in a different country, region or financial market.

Hedging Risk
If the Fund uses a hedging instrument at the wrong time or judges the market conditions incorrectly, or the hedged instrument does not correlate to the risk sought to be hedged, the hedge might be unsuccessful, reduce the Fund’s return, or create a loss. In addition, hedges, even when successful in mitigating risk, may not prevent the Fund from experiencing losses on its investments. Hedging instruments may also reduce or eliminate gains that may otherwise have been available had the Fund not used the hedging instruments.

High Portfolio Turnover Risk
Portfolio turnover is a measure of the Fund’s trading activity over a one-year period. The Fund may engage in active and frequent trading, which could increase the Fund’s transaction costs, have a negative impact on performance, and generate higher capital gain distributions to shareholders than if the Fund had lower portfolio turnover.

Interest Rate Risk
Generally, the value of investments with interest rate risk, such as fixed income securities or derivatives, will move in the opposite direction to movements in interest rates. Factors including central bank monetary policy, rising inflation rates, and changes in general economic conditions may cause interest rates to rise, which could cause the value of the Fund’s investments to decline. Interest rate changes may have a more pronounced effect on the market value of fixed-rate instruments than on floating-rate instruments. The prices of fixed income securities or derivatives are also affected by their durations. Fixed income securities or derivatives with longer durations generally have greater sensitivity to changes in interest rates. For example, if a bond has a duration of eight years, a 1% increase in interest rates could be expected to result in an 8% decrease in the value of the bond. An increase in interest rates can impact markets broadly as well. As of the date of this Prospectus, interest rates are near historic lows and some investments may have negative interest rates. To the extent

the Fund holds an investment with a negative interest rate to maturity, the Fund may generate a negative return on that investment. Conversely, in the future, interest rates may rise, perhaps significantly and/or rapidly, potentially resulting in substantial losses to the Fund.

Investment Risk
An investment in the Fund is not a deposit with a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. When you sell your shares of the Fund, they could be worth less than what you paid for them. Therefore, you may lose money by investing in the Fund.

Leverage Risk
The Fund’s use of derivative instruments may have the economic effect of financial leverage. Financial leverage magnifies the Fund’s exposure to the movements in prices of an asset or class of assets underlying a derivative instrument and may result in increased volatility, which means that the Fund will have the potential for greater losses than if the Fund does not use the derivative instruments that have a leveraging effect. Leverage may result in losses that exceed the amount originally invested and may accelerate the rate of losses. Leverage tends to magnify, sometimes significantly, the effect of any increase or decrease in the Fund’s exposure to an asset or class of assets and may cause the Fund’s net asset value (“NAV”) per share to be volatile. There can be no assurance that the Fund’s use of leverage will be successful.

Liquidity Risk
The Fund is susceptible to the risk that certain investments held by the Fund may have limited marketability, be subject to restrictions on sale, be difficult or impossible to purchase or sell at favorable times or prices or become less liquid in response to market developments or adverse credit events that may affect issuers or guarantors of a security. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such instruments may be volatile. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund’s ability to limit losses. The Fund could lose money if it is unable to dispose of an investment at a time that is most beneficial to the Fund. The Fund may be required to dispose of investments at unfavorable times or prices to satisfy obligations, which may result in losses or may be costly to the Fund. For example, liquidity risk may be magnified in rising interest rate environments in the event of higher than normal redemption rates. Unexpected redemptions may force the Fund to sell certain investments at unfavorable prices to meet redemption requests or other cash needs. Judgment plays a greater role in pricing illiquid investments than in investments with more active markets.

Market Risk
The Fund is subject to the risk that the securities markets will move down, sometimes rapidly and unpredictably, based on overall economic conditions and other factors, which may negatively affect the Fund’s performance. Equity securities generally have greater price volatility than fixed income securities, although under certain market conditions fixed income securities may have comparable or greater price volatility. During a general downturn in the securities markets, multiple assets may decline in value simultaneously. Prices in many financial markets have increased significantly over the last decade, but there have also been periods of adverse market and financial developments and cyclical change during that timeframe, which have resulted in unusually high levels of volatility in domestic and foreign financial markets that has caused losses for investors and may occur again in the future. The value of a security may decline due to adverse issuer-specific conditions, general market conditions unrelated to a particular issuer, such as changes in interest or inflation rates, or factors that affect a particular industry or industries. Changes in the financial condition of a single issuer or market segment also can impact the market as a whole. Geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes, pandemics, public health crises, natural disasters and related events have led, and in the future may continue to lead, to instability in world economies and markets generally and reduced liquidity in equity, credit and fixed-income markets, which may disrupt economies and markets and adversely affect the value of your investment. Changes in value may be temporary or may last for extended periods.

Policy changes by the U.S. government and/or Federal Reserve and political events within the U.S. and abroad, such as changes in the U.S. presidential administration and Congress, the U.S. government’s inability at times to agree on a long-term budget and deficit reduction plan, the threat of a federal government shutdown and threats not to increase the federal government’s debt limit, may affect investor and consumer confidence and may adversely impact financial markets and the broader economy, perhaps suddenly and to a significant degree.

Markets and market participants are increasingly reliant upon both publicly available and proprietary information data systems. Data imprecision, software or other technology malfunctions, programming inaccuracies, unauthorized use or access, and similar circumstances may impair the performance of these systems and may have an adverse impact upon a single issuer, a group of issuers, or the market at large.

The financial markets generally move in cycles, with periods of rising prices followed by periods of declining prices. The value of your investment may reflect these fluctuations.

Recent Market Events Risk. An outbreak of infectious respiratory illness caused by a novel coronavirus, known as COVID-19, was first detected in late 2019 and has subsequently spread globally. The transmission of COVID-19 and efforts to contain its spread have resulted, and may continue to result, in significant disruptions to business operations, widespread business closures and layoffs, travel restrictions and closed borders, prolonged quarantines and stay-at-home orders, disruption of and delays in healthcare service preparation and delivery, service and event changes, and lower consumer demand, as well as general concern and uncertainty that has negatively affected the global economy. The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior. Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. Moreover, the risks discussed herein associated with an investment in the Fund may be increased.

The Federal Reserve has spent hundreds of billions of dollars to keep credit flowing through the economy. However, the Federal Reserve recently began to reduce its interventions as the economy improved and inflation accelerated. Concerns about the markets’ dependence on the Federal Reserve’s provision of liquidity have grown as a result. High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons.

Interest rates have been unusually low in recent years in the U.S. and abroad, and central banks reduced rates further in an effort to combat the economic effects of the COVID-19 pandemic. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes. The U.S. Federal Reserve has started to raise interest rates, in part to address an increase in the annual

inflation rate in the U.S. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

Slowing global economic growth, risks associated with the United Kingdom’s departure from the European Union on December 31, 2020, commonly referred to as “Brexit,” and a trade agreement between the United Kingdom and the European Union, the risks associated with ongoing trade negotiations with China, the possibility of changes to some international trade agreements, tensions, war, or open conflict between nations, such as between Russia and Ukraine, or political or economic dysfunction within some nations that are major producers of oil could affect the economies of many nations, including the United States, in ways that cannot necessarily be foreseen at the present time. Russia’s military invasion of Ukraine beginning in February 2022, the responses and sanctions by the United States and other countries, and the potential for wider conflict have had, and could continue to have, severe adverse effects on regional and global economies and could further increase volatility and uncertainty in the financial markets.

Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impacts of climate change, including on the demand for and the development of goods and services and related production costs, and the impacts of legislation, regulation and international accords related to climate change, as well as any indirect consequences of regulation or business trends driven by climate change.

Market Direction Risk
Since the Fund will typically hold both long and short positions, an investment in the Fund will involve market risks associated with different types of investment decisions than those made for a typical “long only” fund. The Fund’s results could suffer both when there is a general market advance and the Fund holds significant “short” positions, and when there is a general market decline and the Fund holds significant “long” positions.

Market Timing Risk
The Fund is subject to the risk of market timing activities by investors due to the nature of the Fund’s investments, which requires the Fund, in certain instances, to fair value certain of its investments. Some investors may engage in frequent short-term trading in the Fund to take advantage of any price differentials that may be reflected in the net asset value (“NAV”) of the Fund’s shares. Frequent trading by Fund shareholders poses risks to other shareholders in the Fund, including (i) the dilution of the Fund’s NAV, (ii) an increase in the Fund’s expenses, and (iii) interference with the ability to execute efficient investment strategies.

Model and Data/Programming Error Risk
The success of the sub-advisor’s investment strategy depends largely on the effectiveness of its quantitative research models and investment programs. Models (including quantitative models), data, and investment programs are used to screen potential investments for the Fund. When models or data prove to be incorrect or incomplete, any decisions made in reliance thereon expose the Fund to potential risks and programs may not react as expected to market events, resulting in losses for the Fund. Some of the models used by the sub-advisor are predictive in nature. The use of predictive models has inherent risks. Because predictive models are usually constructed based on historical data supplied by third parties, the success of relying on such models may depend heavily on the accuracy and reliability of the supplied historical data. There is no assurance that the models are complete or accurate, or representative of future market cycles, nor will they always be beneficial to the Fund if they are accurate. Additionally, programs may become outdated or experience malfunctions which may not be identified by the sub-advisor and therefore may also result in losses to the Fund. These models and programs may negatively affect Fund performance for various other reasons, including human judgment, inaccuracy of historical data and non-quantitative factors (such as market or trading system dysfunctions, investor fear or overreaction).

Models and data are known to have errors, omissions, imperfections and malfunctions (collectively, “System Events”). The sub-advisor seeks to reduce the incidence and impact of System Events, to the extent feasible, through a combination of internal testing, simulation, real-time monitoring, and use of independent safeguards in the overall portfolio management process and often in the software code itself. Despite such testing, monitoring and independent safeguards, System Events will result in, among other things, the execution of unanticipated trades, the failure to execute anticipated trades, delays in the execution of anticipated trades, the failure to properly allocate trades, the failure to properly gather and organize available data, the failure to take certain hedging or risk reducing actions and/or the taking of actions which increase certain risk(s) - all of which may have materially adverse effects on the Fund. System Events in third-party provided Data are generally entirely outside the control of the sub-advisor.

Non-Diversification Risk
The Fund is non-diversified, which means it may focus its investments in the securities of a comparatively small number of issuers. Investments in securities of a limited number of issuers exposes the Fund to greater market risk, price volatility and potential losses than if assets were diversified among the securities of a greater number of issuers.

Obsolescence Risk
The Fund is unlikely to be successful in the deployment of its quantitative investment strategies unless the assumptions underlying the models are realistic and either remain realistic and relevant in the future or are adjusted to account for changes in the overall market environment. If such assumptions are inaccurate or become inaccurate and are not promptly adjusted, it is likely that profitable trading signals will not be generated. If and to the extent that the models do not reflect certain factors, and the sub-advisor does not successfully address such omission through its testing and evaluation and modify the models accordingly, major losses may result — all of which will be borne by the Fund.

Other Investment Companies Risk
To the extent that the Fund invests in shares of other registered investment companies, the Fund will indirectly bear the fees and expenses charged by those investment companies in addition to the Fund’s direct fees and expenses. To the extent the Fund invests in other investment companies that invest in equity securities, fixed income securities and/or foreign securities, or that track an index, the Fund is subject to the risks associated with the underlying investments held by the investment company or the index fluctuations to which the investment company is subject. The Fund will be subject to the risks associated with investments in those companies, including but not limited to the following:

■	Government Money Market Funds Risk. Investments in government money market funds are subject to interest rate risk, credit risk, and market risk.

Quantitative Strategy Risk
The success of the Fund’s investment strategy may depend in part on the effectiveness of the sub-advisor’s quantitative tools for screening securities. These strategies may incorporate factors that are not predictive of a security’s value. The quantitative tools may not react as expected to market events, resulting in losses for the Fund. Additionally, a previously successful strategy may become outdated or inaccurate, which may not be identified by the sub-advisor and therefore may also result in losses.

Redemption Risk
The Fund may experience periods of high levels of redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. The sale of assets to meet redemption requests may create net capital gains, which could cause the Fund to have to distribute substantial capital gains.

Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund. In addition, redemption risk is heightened during periods of declining or illiquid markets. A rise in interest rates or other market developments may cause investors to move out of fixed income securities on a large scale. During periods of heavy redemptions, the Fund may borrow funds through the interfund credit facility or from a bank line of credit, which may increase costs. Heavy redemptions could hurt the Fund’s performance.

Risk Management
Risk is an essential part of investing. No risk management program can eliminate the Fund’s exposure to adverse events; at best, it can only reduce the possibility that the Fund will be affected by such events, and especially those risks that are not intrinsic to the Fund’s investment program. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

Segregated Assets Risk
In connection with certain transactions that may give rise to future payment obligations, the Fund may be required to maintain a segregated amount of, or otherwise earmark, cash or liquid securities to cover the obligation. Segregated assets generally cannot be sold while the position they are covering is outstanding, unless they are replaced with other assets of equal value. The need to segregate cash or other liquid securities could limit the Fund’s ability to pursue other opportunities as they arise.

Short Position Risk
The Fund will incur a loss as a result of a short position if the price of the instrument sold short increases in value between the date of the short sale and the date on which an offsetting position is purchased. Short positions may be considered speculative transactions and involve special risks, including greater reliance on the sub-advisor’s ability to accurately anticipate the future value of a security or instrument. As there is potentially no limit on the amount that the security that the Fund is required to purchase may have appreciated, the Fund’s losses are potentially unlimited in a short position transaction, particularly in cases where the Fund is unable to close out its short position. The Fund may invest the proceeds of a short sale and, therefore, be subject to the effect of leverage, in that short selling may amplify changes in the Fund’s NAV since it may increase the exposure of the Fund to certain markets and may increase losses and the volatility of returns.

Sovereign Debt Risk
Sovereign debt securities are subject to risk of payment delays or defaults due to, among other things: (1) country cash flow problems, (2) insufficient foreign currency reserves, (3) political considerations, (4) large debt positions relative to the country’s economy, (5) policies toward foreign lenders or investors, (6) the failure to implement economic reforms required by the International Monetary Fund or other multilateral agencies, or (7) an inability or unwillingness to repay debts. A governmental entity that defaults on an obligation may request additional time in which to repay loans, may request further loans, or may seek to restructure its obligations to reduce interest rates or outstanding principal. There is no legal process for collecting sovereign debt that a government does not pay, nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected.

Subsidiary Risk
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 principal risks of the Subsidiary are listed in this section of the Prospectus as principal risks of the Fund. There can be no assurance that the investment objective of the Subsidiary will be achieved or that, as a result, the investment objective of the Fund will be achieved. The Subsidiary is not registered under the Investment Company Act, and, unless otherwise noted in this Prospectus, is not subject to all the investor protections of the Investment Company Act. In addition, 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 operate as described in this Prospectus and the SAI and could adversely affect the Fund’s performance.

Tax Risk
To qualify as a “regulated investment company” under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) (“RIC”), the Fund must, among other requirements, derive at least 90% of its gross income for each taxable year from “qualifying income,” which is described in more detail in the “Tax Information” section of the SAI. Income from certain commodity-linked derivative instruments in which the Fund invests is not considered qualifying income. The Fund will therefore restrict its income from direct investments in those instruments, such as commodity-linked swaps, to a maximum of 10% of its gross income for each taxable year. The Fund’s investment in the Subsidiary is expected to provide the Fund with exposure to the commodities markets within the limitations of the federal tax requirements of Subchapter M. Treasury regulations provide that income inclusions of a RIC from a controlled foreign corporation (“CFC”), such as the Subsidiary, in which the RIC invests as part of its business of investing in stock and securities, are qualifying income for the RIC whether or not the CFC makes distributions to the RIC out of its associated earnings and profits for the applicable taxable year. See “Tax Information” in the SAI for further information regarding RIC’s federal income tax treatment of income from CFCs and commodity-linked instruments. The federal income tax treatment of the Fund’s commodity-linked investments and income from the Subsidiary may be materially adversely affected by future legislation, other Treasury regulations, and/or guidance issued by the IRS that could affect whether income from such investments is qualifying income under Subchapter M or otherwise materially affect the character, timing or recognition, and/or amount of the Fund’s taxable income and/or net capital gains and, therefore, the distributions the Fund makes.

Trading System and Execution of Orders Risk
The sub-advisor relies extensively on computer programs, systems, technology, data and models to implement its execution strategies and algorithms. The sub-advisor’s investment strategies, trading strategies and algorithms depend on its ability to establish and maintain an overall market position in a combination of financial instruments selected by the sub-advisor. There is a risk that the sub-advisor’s proprietary algorithmic trading systems may not be able to adequately react to a market event without serious disruption. Further, trading strategies and algorithms may malfunction, causing severe losses. The successful operation of the computer programs, systems, technology, data and models depends in part on the sub-advisor’s ability to ensure those systems remain operational and that appropriate disaster recovery procedures are in place. While the sub-advisor has employed tools to allow for human intervention to respond to significant system malfunctions, it cannot be guaranteed that losses will not occur in such circumstances as unforeseen market events, disruptions and execution system issues.

U.S. Government Securities Risk
A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed only as to the timely payment of interest and principal when held to maturity. The market prices for such securities are not guaranteed and will fluctuate. U.S. government securities are also subject to credit risk, interest rate risk and market risk. The rising U.S. national debt may lead to adverse impacts on the value of U.S. government securities due to potentially higher costs for the U.S. government to obtain new financing.

U.S. Treasury Obligations Risk
The value of U.S. Treasury obligations may vary due to changes in interest rates. In addition, changes to the financial condition or credit rating of the U.S. government may cause the value of the Fund’s investments in obligations issued by the U.S. Treasury to decline. Certain political events in the U.S., such as a prolonged government shut down, may also cause investors to lose confidence in the U.S. government and may cause the value of U.S. Treasury obligations to decline.

Valuation Risk
The Fund may value certain assets at a price different from the price at which they can be sold. This risk may be especially pronounced for investments that are illiquid or may become illiquid, or securities that trade in relatively thin markets and/or markets that experience extreme volatility. The Fund’s ability to value its investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

Volatility Risk
The Fund may have investments that appreciate or decrease significantly in value over short periods of time. This may cause the Fund’s NAV to experience significant increases or declines in value over short periods of time.

Zero Coupon Securities Risk
Zero coupon securities are securities that do not make periodic interest payments. Accordingly, zero coupon securities usually trade at a deep discount from their face or par value and will be subject to greater fluctuations in market value in response to changing interest rates than debt obligations of comparable maturities that make current distribution of interest in cash.

Risk Nondiversified Status [Text]

rr_RiskNondiversifiedStatus

Non-Diversification RiskThe Fund is non-diversified, which means it may focus its investments in the securities of a comparatively small number of issuers. Investments in securities of a limited number of issuers exposes the Fund to greater market risk, price volatility and potential losses than if assets were diversified among the securities of a greater number of issuers.

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 income taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. The return after taxes on distributions and sale of Fund shares may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. If you are a tax-exempt entity or hold your Fund shares through a tax-deferred arrangement, such as an individual retirement account (“IRA”) or a 401(k) plan, the after-tax returns do not apply to your situation. After-tax returns are shown only for Investor Class shares of the Fund; after-tax returns for other share classes will vary.
