These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities that pay dividends. The Fund may invest in companies of any market capitalization. Although the Fund invests primarily in domestic securities, it may also invest in securities of foreign companies, including companies in emerging markets. The Fund mainly invests in common stocks but may invest up to 10% of its net assets in master limited partnerships (“MLPs”) and up to 10% of its net assets in convertible securities. The Fund may invest in convertible securities that are rated below investment grade (commonly known as “junk bonds”) or, if unrated, are determined by the Portfolio Managers to be of comparable quality.

 

The Portfolio Managers use bottom-up, fundamental security analysis to identify companies that they believe have sustainable and growing dividends, and ideally seek to buy them when they appear temporarily out-of-favor or undervalued by the market. The price of the company’s securities in relation to its cash flow, earnings, dividends, book value and asset value, both historical and prospective, are key determinants in the security selection process. Emphasis is also placed on identifying companies undergoing changes that the Portfolio Managers believe will enhance shareholder value in the future, including changes in operations, management, capital allocation, strategies and product offerings.

 

The Fund may also invest in real estate investment trusts (“REITs”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, when other opportunities appear more attractive or when the Portfolio Managers believe the holding has grown too large relative to the rest of the portfolio.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities that pay dividends, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change

 

based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Master Limited Partnership Risk. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary 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, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies, and may be difficult to value. Distributions from an MLP may consist in part of a return of the amount originally invested, which would not be taxable to the extent the distributions do not exceed the investor’s adjusted basis in its MLP interest. These reductions in the Fund’s adjusted tax basis in the MLP securities will increase the amount of gain (or decrease the amount of loss) recognized by the Fund on a subsequent sale of the securities.

 

Effective for taxable years beginning after December 31, 2017 and before January 1, 2026, the Internal Revenue Code of 1986, as amended (the “Code”), generally allows individuals and certain other non-corporate entities, such as partnerships, a deduction for 20% of “qualified publicly traded partnership income” such as income from MLPs. However, the Code does not include any provision for a regulated investment company to pass the character of its qualified publicly traded partnership income through to its shareholders. As a result, although the Treasury Department has announced that it is considering adopting regulations to provide a pass-through, an investor who invests directly in MLPs will be able to receive the benefit of that deduction, while a shareholder in the Fund currently will not.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In

 

addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries. These include securities of companies (1) that are traded principally on a stock exchange or over-the-counter in emerging market countries, (2) that are organized under the laws of and have a principal office in emerging market countries, or (3) that derive 50% or more of their total revenues from, and/or have 50% or more of their total assets in, goods produced, sales made, profits generated or services performed in emerging market countries. The Fund considers emerging market countries to be countries included in the MSCI Emerging Markets Index.

 

The Portfolio Manager uses a bottom-up, research-driven securities selection approach focusing on businesses with a recent history of high returns while factoring in economic, legislative and business developments to identify countries and sectors that he believes may be particularly attractive. As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager believes that in-depth, strategic and financial research is the key to identifying undervalued companies and seeks to identify companies with the following characteristics: stock prices undervalued relative to his view of long-term cash flow growth potential; industry leadership; potential for significant improvement in the company’s business; or strong financial characteristics, corporate governance practices, and management track record.

 

The Fund seeks to reduce risk by diversifying among many industries. At times, the Portfolio Manager may emphasize certain sectors that he believes will benefit from market or economic trends. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions.

 

The Fund may invest in companies of any market capitalization. Equity securities in which the Fund may invest include common and preferred stocks, convertible securities, rights and warrants to purchase common stock, depositary receipts and China A-shares using the “connect programs” of local stock exchanges in China, such as the Shanghai-Hong Kong Stock Connect Program, the Shenzhen-Hong Kong Stock Connect Program or other similar programs. The Fund may invest in exchange traded funds (“ETFs”). The Fund may also invest in foreign real estate companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal.

 

The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Risks of Investments in China A-shares through Stock Connect Programs. There are significant risks inherent in investing in China A-shares through “Connect Programs” of local stock exchanges in China, namely the Shanghai-Hong Kong Stock Connect Program (“Shanghai Connect Program”) and the Shenzhen-Hong Kong Stock Connect Program (“Shenzhen Connect Program”). The Chinese investment and banking systems are materially different in nature from many developed markets, which exposes investors to risks that are different from those in the U.S. The Connect Programs are subject to daily quota limitations, and an investor cannot purchase and sell the same security on the same trading day, which may restrict the Fund’s ability to invest in China A-shares through the Connect Programs and to enter into or exit trades on a timely basis. If either one or both markets involved in a particular Connect Program are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-shares in a timely manner under such Connect Program, which could adversely affect the Fund’s performance. Only certain China A-shares are eligible to be accessed through the Connect Programs. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Connect Programs.

 

Further regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the Connect Programs. The future impact of this integration of Chinese and foreign markets is unclear and the actual effect on the market for trading China A-shares with the introduction of large numbers of foreign investors is unknown.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying

 

foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Most economies in the Greater China region are generally considered emerging markets and carry the risks associated with emerging markets, as well as risks particular to the region. Events in any one country within the region may impact other countries in the region or the Greater China region as a whole. The economies, industries, and securities and currency markets of the Greater China region may be adversely affected by slow economic activity worldwide, protectionist trade policies, dependence on exports and international trade, currency devaluations and other currency exchange rate fluctuations, restrictions on monetary repatriation, increasing competition from Asia’s low-cost emerging economies, environmental events and natural disasters that may occur in the Greater China region, and military conflicts either in response to social unrest or with other countries.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for

 

the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and exchange-traded funds (ETFs), its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses.

 

An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for

 

their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

Risks of Investing in Variable Interest Entities. For purposes of raising capital offshore on exchanges outside of China, including on U.S. exchanges, many Chinese-based operating companies are structured as entities commonly-referred to as variable interest entities (“VIEs”). In a typical VIE structure, the onshore PRC-based operating company is the VIE and establishes an entity, which is typically offshore in a foreign jurisdiction, such as the Cayman Islands. The offshore entity lists on a foreign exchange and enters into contractual arrangements with the VIE. This structure enables PRC companies in which the PRC government restricts foreign ownership to raise capital from foreign investors. While the offshore entity has no legal equity ownership of the VIE, its contractual arrangements with the VIE permit the offshore entity to consolidate the VIE’s financial statements with its own for FASB accounting purposes and provide for economic exposure to the performance of the underlying onshore PRC operating company. Therefore, an investor in the listed offshore entity, such as the Fund, will have exposure to the onshore PRC-based operating company only through its contractual arrangements with the VIE and has no legal ownership in the VIE. Furthermore, because the offshore entity only has specific rights provided for in these contractual arrangements with the VIE, its abilities to control the activities of the VIE are limited which may engage in activities that negatively impact investment value. While the VIE structure has been widely adopted, it is not formally or legally recognized under PRC law and therefore there is a risk that the PRC government could restrict the effectiveness of such structures or negatively impact the VIE’s contractual arrangements with the listed offshore entity by making them invalid under PRC laws. If these contracts were found to be unenforceable under PRC law, investors in the listed offshore entity, such as the Fund, may suffer significant losses with little or no recourse available. If the PRC government determines that the contractual agreements involving VIE structures do not comply with PRC law and regulations, including those related to restrictions on foreign ownership, it could subject a VIE to numerous sanctions such as penalties, revocation of business and operating licenses, invalidate or terminate contractual arrangements and/or forfeiture or non-recognition of ownership interest.

 

Warrants and Rights Risk. Warrants and rights do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than certain other types of investments. In addition, the value of a warrant or right does not necessarily change with the value of the underlying securities. The Fund could lose the value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrant’s or right’s expiration date. The market for warrants and rights may be very limited and there may at times not be a liquid secondary market for warrants and rights.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in income-oriented equity securities that the Portfolio Managers believe will be able to grow their dividends over time. The Fund strives to deliver a total return with lower volatility relative to the Russell 1000® Value index.

 

Additionally, the Fund seeks to generate a current yield that is greater than the average current yield for stocks in the Russell 1000 Value Index. By selecting these types of equity securities, the Fund seeks to dampen the market volatility associated with investing in equity securities.

 

The Fund typically employs a “value” approach in selecting investments. The Portfolio Managers use a bottom-up, research driven approach to identify companies that they believe have the ability to sustain and potentially to grow their free cash flow and are trading at a discount to what the Portfolio Managers believe to be their net present values. The approach involves examining companies for the presence of potential catalysts that will lead to the creation of value, such as regulatory changes, competitive shifts, reaccelerating earnings, and corporate/management restructuring. The Portfolio Managers also utilize various measures of value, including price-to-earnings ratios, price-to-book ratios and discounted free cash flows, among others.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund may invest in real estate investment trusts (“REITs”) and other real estate companies, convertible securities (including convertible preferred stock, which receives preference in the payment of dividends) and common stocks. The Fund defines a real estate company as one that derives at least 50% of its revenue or profits from real estate, or has at least 50% of its assets invested in real estate. The Fund may emphasize the real estate and utilities sectors of the market at any given time and may invest up to 40% of its total assets in each of these sectors. The Fund may invest in convertible securities that are rated below investment grade (commonly known as “junk bonds”) or, if unrated, are determined by the Portfolio Managers to be of comparable quality.

 

The Fund also uses derivatives, including futures contracts on individual securities and indices, and options, including writing (selling) calls against positions in the portfolio (“covered calls”) or writing (selling) puts on individual stocks, in an effort to enhance returns.

 

The Fund may invest in companies of any market capitalization. Although the Fund invests primarily in domestic equity securities, it may also invest in equity securities of foreign companies, including those in emerging markets.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, when other opportunities appear more attractive or when the Portfolio Managers believe the security has grown too large relative to the rest of the portfolio.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities, without providing shareholders at least 60 days’ notice. For this purpose, equity securities include common stock, preferred stock and securities convertible into common or preferred stock. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The Fund’s use of derivative instruments will result in leverage, which amplifies the risks that are associated with these markets. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Derivatives Risk. 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, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. 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. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. 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. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund’s ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual 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.

 

Additional risks associated with certain types of derivatives are discussed below:

 

Futures. Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a fund to close out a position when desired. In the absence of such limits, the liquidity of the futures market depends on participants entering into offsetting transactions rather than taking or making delivery. To the extent a Fund enters into futures contracts requiring physical delivery (e.g., certain commodities contracts), the inability of the Fund to take or make physical delivery can negatively impact performance.

 

Options. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market

 

countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their

 

approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

If the Fund emphasizes the real estate sector, the utilities sector, or both sectors, your investment in the Fund will be linked to the performance of one or both sectors and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

Utility Companies Risk. Utility companies are sensitive to changes in interest rates and other economic conditions, government regulation, uncertainties created by deregulation, environmental protection or energy conservation policies and practices, the level and demand for services, and the cost of technological advances and the possible inability to implement them at opportune times. In addition, securities of utility companies are volatile and may underperform in a sluggish economy.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. For Class A and Institutional Class shares, your costs would be the same whether you sold your shares or continued to hold them at the end of each period. Actual performance and expenses may be higher or lower.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio, consisting mainly of common stocks of companies of any size that are selected using a fundamental, research driven approach.

 

Under normal market conditions, the Fund typically holds a limited number of stocks of U.S. and non-U.S. companies, including companies in emerging markets. Because of this, the Fund may at times be substantially over- and under-weighted in certain economic sectors.

 

The Portfolio Managers, with the assistance of Neuberger Berman research analysts, look for what they believe to be undervalued companies. Factors in identifying these firms may include depressed valuations, a history of above-average returns, an established market niche, and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with investing in a smaller number of stocks.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund may invest in depositary receipts.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target valuation, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value

 

of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in

 

the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the

 

Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of

 

a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in U.S. and non-U.S. equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies, including rights and warrants, and convertible and preferred securities. The Fund defines a real estate company as one that derives at least 50% of its revenue or profits from real estate, or has at least 50% of its assets invested in real estate.

 

Under normal market conditions, the Fund will invest at least 40% of its total assets (unless market conditions are not deemed favorable by the Portfolio Managers, in which case the Fund would invest at least 30% of its total assets) in securities that (a) are organized or located outside the U.S., (b) trade primarily in a market located outside the U.S., or (c) derive at least 50% of their revenue or profits from business outside the U.S. or have at least 50% of their assets outside the U.S. The Fund will allocate its assets among various regions and countries, including the United States. The Fund is not limited in the extent to which it may invest in real estate equity securities of companies domiciled in emerging market countries. The Fund may also invest in securities of foreign companies in the form of depositary receipts. The Fund generally will invest in convertible securities only if, in the view of the Portfolio Managers, the conversion feature represents a significant element of the securities’ value.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade or below investment grade (commonly known as “junk bonds”), provided that, at the time of purchase, they are rated at least B by S&P Global Ratings or Moody’s Investor Service (or comparably rated by at least one independent credit rating agency) or, if unrated by either of these, determined by the Portfolio Managers to be of comparable quality. The Fund does not normally continue to hold securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions. The Fund may invest in companies across all market capitalizations.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in U.S. and non-U.S. equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in market values or company circumstances will not require the Fund to dispose of a holding.
Strategy Portfolio Concentration [Text] rr_StrategyPortfolioConcentration To pursue its goal, the Fund normally invests at least 80% of its net assets in U.S. and non-U.S. equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies, including rights and warrants, and convertible and preferred securities. The Fund defines a real estate company as one that derives at least 50% of its revenue or profits from real estate, or has at least 50% of its assets invested in real estate.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

Warrants and Rights Risk. Warrants and rights do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than certain other types of investments. In addition, the value of a warrant or right does not necessarily change with the value of the underlying securities. The Fund could lose the value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrant’s or right’s expiration date. The market for warrants and rights may be very limited and there may at times not be a liquid secondary market for warrants and rights.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues

 

and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 53% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity investments that are tied economically to the Greater China region. Green Court Capital Management Limited, the Fund’s sub-adviser, considers the Greater China region to include mainland China, Hong Kong, Macau and Taiwan. The Fund’s equity investments include both equity securities and equity-linked investments, which may be listed or traded on recognized or over-the-counter markets located both inside and outside of the Greater China region, including, without limitation, in the United States, the United Kingdom, Singapore and Japan. An equity investment will be considered to be tied economically to the Greater China region if the issuer is domiciled in the Greater China region or has at least 50% of its assets in, or derives 50% or more of its revenues or profits from, the Greater China region, or if the equity investment’s returns are linked to the performance of such an issuer. The Fund’s equity investments primarily will consist of investments in equity securities, including common stock, preferred stock, and depositary receipts.

 

Securities of companies located in China include China A-shares, China B-shares, and China H-shares, among others. Foreign ownership of China A-shares is subject to certain limitations set by the Chinese government. The Fund may get exposure to China A-shares by investing in equity-linked investments (which are derivative instruments) issued by financial institutions, including, without limitation, participatory notes and other structured notes, swaps, including total return swaps and contracts for differences (i.e., an arrangement in which the parties agree that their return (or loss) will be based on the relative performance of two different groups or baskets of securities), and low exercise priced options (“LEPOs”) (i.e., instruments that pay the holder the difference in price of the underlying security between the date the LEPO was purchased and the date it is sold). The Fund may also invest in China A-shares using the “connect programs” of local stock exchanges in China, such as the Shanghai-Hong Kong Stock Connect Program, the Shenzhen-Hong Kong Stock Connect Program or other similar programs, or by using other methods, subject to any required approvals.

 

The Fund may invest in companies of any market capitalization, but intends to invest generally in mid- and large-capitalization companies that the Portfolio Managers believe are undervalued in an attempt to outperform the average return of the Fund’s benchmark over the long-term.

 

Listed companies in the Greater China region are not as well researched as companies in other markets. This may lead to high variability of returns for companies in the Greater China region, even within the same sector. Because of this, the Portfolio Managers employ a bottom-up, research intensive and fundamentals-driven approach to selecting investments for the Fund. The Portfolio Managers endeavor to gain an understanding of companies through discussions with suppliers, distributors, clients, competitors and government agencies. This is a process which they believe is a key element to investing in inefficient markets. The Portfolio Managers also make on-going assessments of macroeconomic and market factors to augment their selection process.

 

The Portfolio Managers focus on understanding key issues that affect valuations and identifying investments they believe are undervalued. Generally, the Portfolio Managers seek to invest in companies that have strong recurring operating cash flows where revenues and earnings are growing from their core businesses versus relying on new products in untested markets. The Portfolio Managers consider the perceived downside risk of a position before including the position in the Fund. Allocation to each position

 

is dependent on a number of factors including, but not limited to: conviction in the company, target price, correlation across positions and perceived downside risk.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends. In particular, the Portfolio Managers will focus on certain areas they believe will benefit from the long-term growth in the Greater China region including opportunities related to domestic consumption, environmental and clean technology, health care and advanced technologies.

 

Although the Portfolio Managers seek to invest for the long-term, the Fund may engage in active and frequent trading when the Portfolio Managers gradually build a position or during periods of high market volatility in the Greater China region.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a position when it reaches a target price or when there are changes to macroeconomic factors, markets, sectors and/or the company that would alter the Portfolio Managers’ assumptions about the company.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity investments that are tied economically to the Greater China region, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Risks of Investments in China A-shares through Stock Connect Programs. There are significant risks inherent in investing in China A-shares through “Connect Programs” of local stock exchanges in China, namely the Shanghai-Hong Kong Stock Connect Program (“Shanghai Connect Program”) and the Shenzhen-Hong Kong Stock Connect Program (“Shenzhen Connect Program”). The Chinese investment and banking systems are materially different in nature from many developed markets, which exposes investors to risks that are different from those in the U.S. The Connect Programs are subject to daily quota limitations, and an investor cannot purchase and sell the same security on the same trading day, which may restrict the Fund’s ability to invest in China A-shares through the Connect Programs and to enter into or exit trades on a timely basis. If either one or both markets involved in a particular Connect Program are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-shares in a timely manner under such Connect Program, which could adversely affect the Fund’s performance. Only certain China A-shares are eligible to be accessed through the Connect Programs. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Connect Programs.

 

Further regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the Connect Programs. The future impact of this integration of Chinese and foreign markets is unclear and the actual effect on the market for trading China A-shares with the introduction of large numbers of foreign investors is unknown.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange

 

rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Derivatives Risk. 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, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. 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. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. 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. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund’s ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual 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.

 

Equity-Linked Investment Risk. Equity-linked investments are subject to the same risks as direct investments in securities of the underlying investment. If the underlying investment decreases in value, the value of the equity-linked investment will decrease; however, the performance of such investments may not correlate exactly to the performance of the underlying investments that they seek to replicate. Equity-linked investments are also subject to counterparty risk, which is the risk that the issuer of such investment -- which is different from the issuer of the underlying investment -- may be unwilling or unable to fulfill its obligations. There is no guarantee that a liquid market will exist or that the counterparty or issuer of such investments will be willing to repurchase them when the Fund wishes to sell them.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market

 

countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as participatory notes (or “P-notes”) or other derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Greater China Region Risk. The Fund’s performance is expected to be closely tied to economic, political, diplomatic, and social conditions within the Greater China region and to be more volatile than the performance of more geographically diversified funds. Most economies in the Greater China region are generally considered emerging markets and carry the risks associated with emerging markets, as well as risks particular to the region. Events in any one country within the region may impact other countries in the region or the Greater China region as a whole. The economies, industries, and securities and currency markets of the Greater China region may be adversely affected by slow economic activity worldwide, protectionist trade policies, dependence on exports and international trade, currency devaluations and other currency exchange rate fluctuations, restrictions on monetary repatriation, increasing competition from Asia’s low-cost emerging economies, environmental events and natural disasters that may occur in the Greater China region, and military conflicts either in response to social unrest or with other countries. In addition, the tax laws and regulations in mainland China are subject to change, possibly with retroactive effect.

 

The ongoing U.S.-China “trade war” may affect China’s economy substantially, as the U.S. has been a principal trading partner of China. The ability of China to restructure its foreign trade relationships, and whether China is motivated to stop supporting its currency or stop trade in certain natural resources, and whether the U.S. government imposes restrictions on U.S. investor participation in certain Chinese investments, including through executive order or other means, may determine to some degree the extent to which its economy will be damaged by the trade war, and these things cannot be predicted at the present time.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate.

 

Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

Risks of Investing in Variable Interest Entities. For purposes of raising capital offshore on exchanges outside of China, including on U.S. exchanges, many Chinese-based operating companies are structured as entities commonly-referred to as variable interest entities (“VIEs”). In a typical VIE structure, the onshore PRC-based operating company is the VIE and establishes an entity, which is typically offshore in a foreign jurisdiction, such as the Cayman Islands. The offshore entity lists on a foreign exchange and enters into contractual arrangements with the VIE. This structure enables PRC companies in which the PRC government restricts foreign ownership to raise capital from foreign investors. While the offshore entity has no legal equity ownership of the VIE, its contractual arrangements with the VIE permit the offshore entity to consolidate the VIE’s financial statements with its own for FASB accounting purposes and provide for economic exposure to the performance of the underlying onshore PRC operating company. Therefore, an investor in the listed offshore entity, such as the Fund, will have exposure to the onshore PRC-based operating company only through its contractual arrangements with the VIE and has no legal ownership in the VIE. Furthermore, because the offshore entity only has specific rights provided for in these contractual arrangements with the VIE, its abilities to control the activities of the VIE are limited which may engage in activities that negatively impact investment value. While the VIE structure has been widely adopted, it is not formally or legally recognized under PRC law and therefore there is a risk that the PRC government could restrict the effectiveness of such structures or negatively impact the VIE’s contractual arrangements with the listed offshore entity by making them invalid under PRC laws. If these contracts were found to be unenforceable under PRC law, investors in the listed offshore entity, such as the Fund, may suffer significant losses with little or no recourse available. If the PRC government determines that the contractual agreements involving VIE structures do not comply with PRC law and regulations, including those related to restrictions on foreign ownership, it could subject a VIE to numerous sanctions such as penalties, revocation of business and operating licenses, invalidate or terminate contractual arrangements and/or forfeiture or non-recognition of ownership interest.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology

 

disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.
Risk Lose Money [Text] rr_RiskLoseMoney The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.
RIsk Not Insured [Text] rr_RiskNotInsured The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year, as represented by the performance of the Fund’s Institutional Class. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were reflected, returns would be lower than those shown. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy. Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies of any size, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and regions around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of

 

securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the

 

prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year, as represented by the performance of the Fund’s Institutional Class. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were reflected, returns would be lower than those shown. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy. Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges.

 

For Class A and Class C, the performance prior to January 28, 2013, is that of the Fund’s Institutional Class. Because Institutional Class has lower expenses than Class A and Class C, its performance typically would have been better than that of Class A and Class C.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be invested in companies with a market capitalization greater than $2.5 billion at the time of purchase.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange

 

rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among

 

other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, the Fund will invest at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization of no more than $5 billion at the time of purchase.

 

In picking stocks, the Portfolio Manager looks for what he believes to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Manager also considers the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Manager may emphasize certain sectors or industries that he believes offers a better risk/reward opportunity.

 

As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of borrowings for investment purposes, in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be

 

required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small- and mid-capitalization companies, which it defines as those companies with a total market value between $50 million and $10 billion at the time the Fund first invests in them. The Fund may continue to hold or add to a position in a stock after the company’s market value has increased above or decreased below this range.

 

The Fund’s strategy consists of using a bottom-up, research driven approach to identify stocks of companies that are available at market prices below the Portfolio Managers’ estimate of their intrinsic value and that the Portfolio Managers believe have the potential for appreciation in value over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic value, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, certain investment opportunities tend to be mispriced due to market inefficiencies. For example, market inefficiencies may exist at times in the small capitalization segment of the market due to a lack of widely available research on these companies. The Portfolio Managers attempt to exploit these market inefficiencies and look for opportunities to invest in companies they believe to be undervalued, such as companies with the following characteristics:

 

■ Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■ Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■ Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify these types of companies, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that the Portfolio Managers believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company’s stock on the basis of the company’s discount to the Portfolio Managers’ estimate of intrinsic value and the Portfolio Managers’ belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst, such as a merger, liquidation, spin off, or management change. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock. The Portfolio Managers also integrate governance factors into the investment process. They seek to invest in companies that have effective and independent boards composed of diverse, and currently active, CEOs and other C-level executives. They look for companies where management and shareholder interests are aligned (often through high ownership of the company by management), with long-term incentive plans and CEO and management compensation and succession plans in place. The Portfolio Managers also seek out companies that have full transparency and disclosure, effective capital deployment strategies and value enhancing merger and acquisition policies. When appropriate, the Portfolio Managers may engage with portfolio companies regarding directors, strategy and financing in an effort to enhance shareholder value. The Portfolio Managers may also engage on financially material environmental and social issues.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continue to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

 

At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them

 

 

only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Bar Chart and Performance Table [Heading] rr_BarChartAndPerformanceTableHeading PERFORMANCE
Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year, as represented by the performance of the Fund’s Institutional Class. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were reflected, returns would be lower than those shown. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of one or more broad-based market indices. The indices, which are described in “Descriptions of Indices” in the prospectus, have characteristics relevant to the Fund’s investment strategy. Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges.

 

As of May 7, 2010, the Fund became the successor to DJG Small Cap Value Fund L.P., an unregistered limited partnership (“DJG Fund”); DJG Fund was the successor to The DJG Small Cap Value Fund, an unregistered commingled investment account (“DJG Account”). The performance after September 12, 2008 is that of DJG Fund and the performance from July 8, 1997 (the Fund’s commencement of operations) to September 11, 2008 is that of DJG Account. On May 7, 2010, the DJG Fund

 

 

transferred its assets to the Fund in exchange for the Fund’s Institutional Class shares. The investment policies, objectives, guidelines and restrictions of the Fund are in all material respects equivalent to those of DJG Fund and DJG Account (the “Predecessors”). As a mutual fund registered under the Investment Company Act of 1940, the Fund is subject to certain restrictions under the 1940 Act and the Internal Revenue Code to which the Predecessors were not subject. Had the Predecessors been registered under the 1940 Act and been subject to the provisions of the 1940 Act and the Code, their investment performance may have been adversely affected. The performance information reflects the actual expenses of the Predecessors.

 

The Predecessors did not have distribution policies. The Predecessors were an unregistered limited partnership and an unregistered commingled investment account, did not qualify as regulated investment companies for federal income tax purposes and did not pay dividends or other distributions. As a result of the different tax treatment, we are unable to show the after-tax returns for the Fund prior to May 7, 2010.

 

For each class, the performance prior to May 7, 2010, is that of the Fund’s Predecessors.

 

Returns would have been lower/higher if the investment adviser to the Predecessors and/or the Manager had not reimbursed/recouped certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

To pursue its goals, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Growth Index at the time of purchase.

 

The Portfolio Managers employ a research driven approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment. The Portfolio Managers generally seek to identify what they believe to be faster-growing companies with attractive sales growth and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: balance sheet metrics; profit margin profiles; market share and competitive leadership of the company’s products; sales; cash flow and earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other large-capitalization companies.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund seeks to reduce risk by investing across many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy that utilizes a process analyzing macroeconomic and/or security-specific circumstances, and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse

 

 

investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include

 

 

registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value,

 

as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. For Class A and Institutional Class shares, your costs would be the same whether you sold your shares or continued to hold them at the end of each period. Actual performance and expenses may be higher or lower.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Index at the time of purchase.

 

The Portfolio Managers employ a disciplined investment strategy when selecting growth stocks. Using fundamental research and quantitative analysis, they look for what they believe to be fast-growing companies with above-average sales and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: financial condition (such as debt to equity ratio); market share and competitive leadership of the company’s products; earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other mid-cap companies.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Exposure Risk. Securities issued by U.S. entities with substantial foreign operations or holdings, or issued by foreign entities listed on a U.S. exchange, may involve additional risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Value Index at the time of purchase.

 

The Fund’s strategy consists of using a bottom-up, fundamental research driven approach to identify stocks of companies that are trading below the Portfolio Managers’ estimate of their intrinsic value and that they believe have the potential for appreciation over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic worth, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, valuations of certain types of companies are often distorted by market inefficiencies, which can lead to attractive investment opportunities. The Portfolio Managers attempt to exploit recurring market inefficiencies among the following types of companies as the Portfolio Managers believe these types of companies are often misunderstood and mispriced by investors.

 

■ Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■ Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■ Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify potential investment opportunities, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that they believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company based on its discount to their estimate of intrinsic value and their belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst that can be expected to close the value/price gap, such as a merger, restructuring, liquidation, spin-off, major management change, share repurchase, or capital reallocation. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continues to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 16% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio, consisting mainly of common stocks of companies that are selected using a fundamental, bottom-up research approach. The Fund may hold stocks of companies of any market capitalization and in any sector. Under normal market conditions, the Fund typically will hold a limited number of stocks.

 

Portfolio construction is an important component of the investment process and primarily consists of three distinct investment categories: Special Situations, Opportunistic, and Classic. Special Situations have unique attributes (e.g., restructurings, spin-offs, post-bankruptcy equities) that require specific methodologies and customized investment research. Opportunistic investments are companies that have become inexpensive for a tangible reason that the Portfolio Manager believes is temporary. Classic investments are those companies with long histories of shareholder-friendly policies, high-quality management teams and consistent operating performance.

 

The Portfolio Manager performs both quantitative and qualitative analysis in an effort to identify companies that he believes have the potential to increase in value. This potential may be realized in many ways, some of which include: free cash flow generation, product or process enhancements, margin increases, and improved capital structure management. Investments are selected primarily based on fundamental analysis of issuers and their potential in light of their financial condition, industry position, market opportunities, senior management teams and any special situations as well as any relevant economic, political and regulatory factors.

 

As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager employs disciplined valuation criteria and dynamic price limits to determine when to buy or sell a stock. The valuation criteria and price limits will change over time as a result of changes in company-specific, industry and market factors. The Portfolio Manager follows a disciplined selling strategy and may sell a stock when it reaches a dynamic price target, when other opportunities appear more attractive, or when the Portfolio Manager’s research indicates deteriorating fundamentals.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

At times, the Portfolio Manager may emphasize certain sectors that he believes will benefit from market or economic trends.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange

 

rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates.

 

Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Special Situations Risk. Companies that are considered “special situations” include, among others: companies that have unrecognized recovery prospects or new management teams; companies involved in restructurings or spin-offs; companies emerging from, or restructuring as a result of, bankruptcy; companies making initial public offerings that trade below their initial offering prices; and companies with a break-up value above their market price. Investing in special situations carries the risk that certain of such situations may not happen as anticipated or the market may react differently than expected to such situations. The securities of companies involved in special situations may be more volatile than other securities, may at times be illiquid, or may be difficult to value.

 

Certain special situations carry the additional risks inherent in difficult corporate transitions and the securities of such companies may be more likely to lose value than the securities of more stable companies.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management

 

team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies. The Fund defines a real estate company as one that derives at least 50% of its revenue from, or has at least 50% of its assets in, real estate.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade securities or below investment grade securities (commonly known as “junk bonds”), provided that, at the time of investment, they are rated at least B by S&P Global Ratings or Moody’s Investors Service, Inc. (or comparably rated by at least one independent credit rating agency) or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund does not normally intend to continue holding securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. The Fund concentrates its assets in the real estate industry. The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care.

 

Some of the REITs and other real estate securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

 

The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, or if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee

 

 

that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value.

 

 

Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there

 

 

is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year, as represented by the performance of the Fund’s Institutional Class. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were reflected, returns would be lower than those shown. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy. Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges.

 

As of June 19, 2012, the Fund changed its investment policy to become “non-diversified” under the Investment Company Act of 1940. Its performance prior to this change might have been different if current policies had been in effect.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 121% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell 2000® Index at the time of initial purchase.

 

The Fund’s strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth, which are underappreciated by the market, durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, change in management and a spin-off or merger. The Portfolio Managers may also invest in anticipation of a catalyst.

 

In analyzing the viability and sustainability of catalysts, the Portfolio Managers evaluate that catalyst’s uniqueness, timing, total potential market and growth potential, as well as assess execution risks, competitive barriers and threats. The Portfolio Managers are also attempting to exploit market inefficiencies that potentially may exist within the small-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. The Portfolio Managers attempt to exploit these market inefficiencies by seeking out and evaluating catalysts which are underappreciated by the market and look for opportunities to invest in companies with the following characteristics:

 

■ Underappreciated Growth: Companies with potentially transformative near-term catalysts that are underappreciated by the market, that the Portfolio Managers believe are capable of advancing the development of underlying corporate fundamentals or, in the case of early development-stage companies, initiating a path to revenue and eventually earnings growth

 

■ Strengthening Growth: More established companies that are endeavoring to expand their product offerings, broadening operational depth and strengthening top- and bottom-line consistency

 

■ Opportunistic Growth: Companies that the Portfolio Managers believe represent an opportunistic valuation play because their potential has yet to be unlocked, they are raising capital or they have fallen out of favor due to what the Portfolio Managers believe is a shorter-term and correctable issue

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading that involves initiating new positions, resizing current positions in response to material developments and in order to maintain an appropriate and attractive risk/reward balance and fully exiting positions in favor of new ideas.

 

The Fund will not change its strategy of normally investing 80% of its net assets in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In

 

 

addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 247 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund seeks to invest primarily in common stocks of mid- to large-capitalization companies that meet the Fund’s quality oriented financial and ESG criteria. The Fund defines mid-capitalization companies as those with a total market capitalization of $2 billion and above and large-capitalization companies as those with a total market capitalization of $10 billion and above, both at the time of initial purchase.

 

The Portfolio Manager employs a fundamental research driven approach to stock selection and portfolio construction, with a focus on long term sustainability issues that, in the judgement of the Portfolio Manager, are financially material. This sustainable investment approach seeks to identify high quality, well-positioned companies with leadership that is focused on ESG issues relevant to their business. In doing such, the Portfolio Manager seeks to identify companies with certain practices, including (i) clear and relevant communication regarding management’s understanding, commitment to, and prioritization of, sustainability issues relevant to the business; (ii) identification and disclosure of material sustainability considerations and management objectives (e.g., sustainability-linked goals and targets, including their supply chain, or executive compensation frameworks linked to such goals and targets); and/or (iii) board-level oversight on material sustainability issues. As part of the focus on quality, the Portfolio Manager looks for solid balance sheets, strong management teams with a track record of success, good cash flow, the prospect for above-average earnings growth and the sustainability of those earnings, as well as of the company’s business model, over the long term. The Portfolio Manager seeks to purchase the stock of businesses that he believes to be well positioned and attractively valued. Among companies that meet these criteria, the Portfolio Manager looks for those that show leadership in environmental, social and governance considerations, including safe and equitable workplace practices and constructive community relations.

 

As part of the focus on long-term sustainability, the Portfolio Manager looks for companies that show leadership in their environmental and workplace practices. The Fund seeks to invest in companies that demonstrate ESG policies in the following areas: (i) environmental issues; (ii) employment practices and diversity policies; (iii) community relations; (iv) supply chain issues; (v) product integrity (e.g., safety, quality) and (vi) disclosure and sustainability reporting.

 

Consistent with the Fund’s ESG Criteria, the Portfolio Manager focuses on identifying companies that are responsive to environmental issues, including those that have identified and communicated climate-related risks and opportunities, have identified and communicated net-zero transition plans, have committed to or are transitioning to facilitate global decarbonization and/or the reduction of other greenhouse gas emissions; are agents of favorable change in workplace policies (particularly for women and minorities); are committed to upholding universal human rights standards; and are good corporate citizens. The Portfolio Manager judges companies on their corporate citizenship overall, considering their accomplishments as well as their goals. While these judgments are inevitably subjective, the Portfolio Manager endeavors to avoid companies that derive revenue from gambling or the production of alcohol, tobacco, weapons, nuclear power or private prisons. Please see the Statement of Additional Information for a detailed description of the Fund’s ESG Criteria.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund seeks to reduce risk by investing across many different industries.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security if he believes it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As a sustainable fund, the Fund is required by the federal securities laws to have a policy, which it cannot change without providing investors at least 60 days’ written notice, of investing at least 80% of its net assets in equity securities selected in accordance with its ESG criteria. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding. In practice, the Portfolio Manager intends to hold only securities selected in accordance with the Fund’s ESG Criteria.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee

 

 

that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

ESG Criteria Risk. The Fund’s application of ESG criteria is designed and utilized to help identify companies that demonstrate the potential to create economic value or reduce risk; however as with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The use of the Fund’s ESG criteria could also affect the Fund’s exposure to certain sectors or industries, and could impact the Fund’s investment performance depending on whether the ESG criteria used are ultimately reflected in the market.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a

 

 

slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 28% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio consisting primarily of U.S. companies whose products and services the Portfolio Managers believe have the potential to deliver positive social and environmental outcomes (“Impact”). The Fund considers securities of U.S. companies to be those that (1) are traded principally on a stock exchange or over-the-counter in the United States, (2) are organized under the laws of and have a principal office in the United States, or (3) derive 50% or more of their total revenues from, and/or have 50% or more of their total assets in, goods produced, sales made, profits generated or services performed in the United States. Companies are selected using a fundamental, bottom-up research approach and proprietary in-depth Impact analysis using quantitative ratios and qualitative scoring frameworks. The Fund may hold stocks of companies of any market capitalization and in any sector. Under normal market conditions, the Fund typically will hold a limited number of stocks.

 

The Portfolio Managers focus on both social and environmental Impact themes while also integrating governance factors into the investment process. Social themes include a company’s ability to deliver sustainable growth and fair employment, increase positive health and safety outcomes, and promote gender and racial equality. Environmental themes include the ability to combat climate change, enable energy transitions, and conserve the natural environment.

 

Portfolio construction is an important component of the investment process and primarily consists of three distinct investment categories: Special Situations, Opportunistic, and Impact Leaders. Special Situations have certain attributes that the Portfolio Managers believe may influence Impact outcomes (e.g., initial public offerings, spin-offs, private investments, changes in capital structure, mergers and acquisitions) and require specific methodologies and customized investment research. Opportunistic investments are companies that the Portfolio Managers believe are temporarily underappreciated by the broader market, given their long- term business and/or Impact potential. Impact Leaders are those companies with a track record of significant Impact, shareholder-oriented management, superior competitive positioning, or that are industry leaders in environmental, social and governance (“ESG”) issues.

 

The Portfolio Managers utilize an integrated approach focused on rigorous Impact analysis, consideration of ESG factors, and assessment of company financials. The Managers perform both quantitative and qualitative analysis in an effort to identify companies that they believe have the potential to increase in value. This potential may be realized in many ways, some of which include: free cash flow generation, product or process enhancements, margin increases, and improved capital structure management. Investments are selected primarily based on fundamental analysis of issuers and their potential in light of the Portfolio Managers’ evaluation of their financial condition, industry position, market opportunities, Impact metrics, ESG factors, senior management teams and any special situations as well as any relevant economic, political and regulatory factors. Environmental and social outcomes will be evaluated on an absolute basis, with the goal of achieving a specific and identifiable positive threshold. Additionally, the contribution of companies to a specific environmental or social outcome will be compared against other companies, which also contribute to that same environmental or social outcome. These factors will be considered both individually and collectively, as part of the Portfolio Managers’ analysis.

 

The Portfolio Managers will invest in accordance with the Fund’s Enhanced Sustainable Exclusion Policy. The policy describes businesses, which may be deemed controversial, and are therefore excluded from investment consideration. Please see the Statement of Additional Information for a detailed description of the Fund’s Enhanced Sustainable Exclusion Criteria.

 

The Portfolio Managers employ disciplined valuation criteria and dynamic price limits to determine when to buy or sell a security.

 

The valuation criteria and price limits will change over time as a result of changes in company-specific, industry and market factors. The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a dynamic price target, when other opportunities appear more attractive, when Impact metrics deteriorate, or when the Portfolio Managers’ research indicates declining fundamentals.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable

 

 

exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in U.S. equity securities, without providing investors at least 60 days’ written notice. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or

 

 

decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Impact and ESG Criteria Risk. The Fund’s application of Impact and ESG criteria, including its adherence to the Fund’s Enhanced Sustainable Exclusion Policy could cause it to sell or avoid some stocks or instruments that in hindsight could have performed well or enhanced the Fund’s risk profile. As with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The Fund may underperform funds that do not follow Impact and ESG criteria. The Fund’s Impact and ESG criteria may also affect the Fund’s exposure to certain sectors or industries, and may impact the Fund’s investment performance depending on whether such sectors or industries are in or out of favor in the market.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

New Fund Risk. The Fund may not be successful in implementing its investment strategy, and its investment strategy may not be successful under all future market conditions, either of which could result in the Fund being liquidated at some future time without shareholder approval and/or at a time that may not be favorable for certain shareholders. New funds may not attract sufficient assets to achieve investment, trading or other efficiencies.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to

 

 

competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Special Situations Risk. Companies that are considered “special situations” include, among others: companies that have unrecognized recovery prospects or new management teams; companies involved in restructurings or spin-offs; companies emerging from, or restructuring as a result of, bankruptcy; companies making initial public offerings that trade below their initial offering prices; and companies with a break-up value above their market price. Investing in special situations carries the risk that certain of such situations may not happen as anticipated or the market may react differently than expected to such situations. The securities of companies involved in special situations may be more volatile than other securities, may at times be illiquid, or may be difficult to value.

 

Certain special situations carry the additional risks inherent in difficult corporate transitions and the securities of such companies may be more likely to lose value than the securities of more stable companies.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value

 

methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 21% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities that pay dividends. The Fund may invest in companies of any market capitalization. Although the Fund invests primarily in domestic securities, it may also invest in securities of foreign companies, including companies in emerging markets. The Fund mainly invests in common stocks but may invest up to 10% of its net assets in master limited partnerships (“MLPs”) and up to 10% of its net assets in convertible securities. The Fund may invest in convertible securities that are rated below investment grade (commonly known as “junk bonds”) or, if unrated, are determined by the Portfolio Managers to be of comparable quality.

 

The Portfolio Managers use bottom-up, fundamental security analysis to identify companies that they believe have sustainable and growing dividends, and ideally seek to buy them when they appear temporarily out-of-favor or undervalued by the market. The price of the company’s securities in relation to its cash flow, earnings, dividends, book value and asset value, both historical and prospective, are key determinants in the security selection process. Emphasis is also placed on identifying companies undergoing

 

changes that the Portfolio Managers believe will enhance shareholder value in the future, including changes in operations, management, capital allocation, strategies and product offerings.

 

The Fund may also invest in real estate investment trusts (“REITs”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, when other opportunities appear more attractive or when the Portfolio Managers believe the holding has grown too large relative to the rest of the portfolio.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities that pay dividends, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Master Limited Partnership Risk. Investing in MLPs involves certain risks related to investing in the underlying assets of the MLPs and risks associated with pooled investment vehicles. MLPs holding credit-related investments are subject to interest rate risk and the risk of default on payment obligations by debt issuers. MLPs that concentrate in a particular industry or a particular geographic region are subject to risks associated with such industry or region. Investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary 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, and they may be subject to more abrupt or erratic price movements than securities of larger or more broadly based companies, and may be difficult to value. Distributions from an MLP may consist in part of a return of the amount originally invested, which would not be taxable to the extent the distributions do not exceed the investor’s adjusted basis in its MLP interest. These reductions in the Fund’s adjusted tax basis in the MLP securities will increase the amount of gain (or decrease the amount of loss) recognized by the Fund on a subsequent sale of the securities.

 

Effective for taxable years beginning after December 31, 2017 and before January 1, 2026, the Internal Revenue Code of 1986, as amended (the “Code”), generally allows individuals and certain other non-corporate entities, such as partnerships, a deduction for 20% of “qualified publicly traded partnership income” such as income from MLPs. However, the Code does not include any provision for a regulated investment company to pass the character of its qualified publicly traded partnership income through to its shareholders. As a result, although the Treasury Department has announced that it is considering adopting regulations to provide a pass-through, an investor who invests directly in MLPs will be able to receive the benefit of that deduction, while a shareholder in the Fund currently will not.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 39% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries. These include securities of companies (1) that are traded principally on a stock exchange or over-the-counter in emerging market countries, (2) that are organized under the laws of and have a principal office in emerging market countries, or (3) that derive 50% or more of their total revenues from, and/or have 50% or more of their total assets in, goods produced, sales made, profits generated or services performed in emerging market countries. The Fund considers emerging market countries to be countries included in the MSCI Emerging Markets Index.

 

The Portfolio Manager uses a bottom-up, research-driven securities selection approach focusing on businesses with a recent history of high returns while factoring in economic, legislative and business developments to identify countries and sectors that he believes may be particularly attractive. As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager believes that in-depth, strategic and financial research is the key to identifying undervalued companies and seeks to identify companies with the following characteristics: stock prices undervalued relative to his view of long-term cash flow

 

 

growth potential; industry leadership; potential for significant improvement in the company’s business; or strong financial characteristics, corporate governance practices, and management track record.

 

The Fund seeks to reduce risk by diversifying among many industries. At times, the Portfolio Manager may emphasize certain sectors that he believes will benefit from market or economic trends. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions.

 

The Fund may invest in companies of any market capitalization. Equity securities in which the Fund may invest include common and preferred stocks, convertible securities, rights and warrants to purchase common stock, depositary receipts and China A-shares using the “connect programs” of local stock exchanges in China, such as the Shanghai-Hong Kong Stock Connect Program, the Shenzhen-Hong Kong Stock Connect Program or other similar programs. The Fund may invest in exchange traded funds (“ETFs”). The Fund may also invest in foreign real estate companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Risks of Investments in China A-shares through Stock Connect Programs. There are significant risks inherent in investing in China A-shares through “Connect Programs” of local stock exchanges in China, namely the Shanghai-Hong Kong Stock Connect Program (“Shanghai Connect Program”) and the Shenzhen-Hong Kong Stock Connect Program (“Shenzhen Connect Program”). The Chinese investment and banking systems are materially different in nature from many developed markets, which exposes investors to risks that are different from those in the U.S. The Connect Programs are subject to daily quota limitations, and an investor cannot purchase and sell the same security on the same trading day, which may restrict the Fund’s ability to invest in China A-shares through the Connect Programs and to enter into or exit trades on a timely basis. If either one or both markets involved in a particular Connect Program are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-shares in a timely manner under such Connect Program, which could adversely affect the Fund’s performance. Only certain China A-shares are eligible to be accessed through the Connect Programs. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Connect Programs.

 

 

Further regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the Connect Programs. The future impact of this integration of Chinese and foreign markets is unclear and the actual effect on the market for trading China A-shares with the introduction of large numbers of foreign investors is unknown.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the

 

securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Most economies in the Greater China region are generally considered emerging markets and carry the risks associated with emerging markets, as well as risks particular to the region. Events in any one country within the region may impact other countries in the region or the Greater China region as a whole. The economies, industries, and securities and currency markets of the Greater China region may be adversely affected by slow economic activity worldwide, protectionist trade policies, dependence on exports and international trade, currency devaluations and other currency exchange rate fluctuations, restrictions on monetary repatriation, increasing competition from Asia’s low-cost emerging economies, environmental events and natural disasters that may occur in the Greater China region, and military conflicts either in response to social unrest or with other countries.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and exchange-traded funds (ETFs), its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses.

 

An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic

 

fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

Risks of Investing in Variable Interest Entities. For purposes of raising capital offshore on exchanges outside of China, including on U.S. exchanges, many Chinese-based operating companies are structured as entities commonly-referred to as variable interest entities (“VIEs”). In a typical VIE structure, the onshore PRC-based operating company is the VIE and establishes an entity, which is typically offshore in a foreign jurisdiction, such as the Cayman Islands. The offshore entity lists on a foreign exchange and enters into contractual arrangements with the VIE. This structure enables PRC companies in which the PRC government restricts foreign ownership to raise capital from foreign investors. While the offshore entity has no legal equity ownership of the VIE, its contractual arrangements with the VIE permit the offshore entity to consolidate the VIE’s financial statements with its own for FASB accounting purposes and provide for economic exposure to the performance of the underlying onshore PRC operating company. Therefore, an investor in the listed offshore entity, such as the Fund, will have exposure to the onshore PRC-based operating company only through its contractual arrangements with the VIE and has no legal ownership in the VIE. Furthermore, because the offshore entity only has specific rights provided for in these contractual arrangements with the VIE, its abilities to control the activities of the VIE are limited which may engage in activities that negatively impact investment value. While the VIE structure has been widely adopted, it is not formally or legally recognized under PRC law and therefore there is a risk that the PRC government could restrict the effectiveness of such structures or negatively impact the VIE’s contractual arrangements with the listed offshore entity by making them invalid under PRC laws. If these contracts were found to be unenforceable under PRC law, investors in the listed offshore entity, such as the Fund, may suffer significant losses with little or no recourse available. If the PRC government determines that the contractual agreements involving VIE structures do not comply with PRC law and regulations, including those related to restrictions on foreign ownership, it could subject a VIE to numerous sanctions such as penalties, revocation of business and operating licenses, invalidate or terminate contractual arrangements and/or forfeiture or non-recognition of ownership interest.

 

Warrants and Rights Risk. Warrants and rights do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than certain other types of investments. In addition, the value of a warrant or right does not necessarily change with the value of the underlying securities. The Fund could lose the value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrant’s or right’s expiration date. The market for warrants and rights may be very limited and there may at times not be a liquid secondary market for warrants and rights.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the

 

 

Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of

 

 

a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies of any size, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and regions around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the

 

 

Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be invested in companies with a market capitalization greater than $2.5 billion at the time of purchase.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, the Fund will invest at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization of no more than $5 billion at the time of purchase.

 

In picking stocks, the Portfolio Manager looks for what he believes to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Manager also considers the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Manager may emphasize certain sectors or industries that he believes offers a better risk/reward opportunity.

 

As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of borrowings for investment purposes, in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history

 

 

of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small- and mid-capitalization companies, which it defines as those companies with a total market value between $50 million and $10 billion at the time the Fund first invests in them. The Fund may continue to hold or add to a position in a stock after the company’s market value has increased above or decreased below this range.

 

The Fund’s strategy consists of using a bottom-up, research driven approach to identify stocks of companies that are available at market prices below the Portfolio Managers’ estimate of their intrinsic value and that the Portfolio Managers believe have the potential for appreciation in value over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic value, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, certain investment opportunities tend to be mispriced due to market inefficiencies. For example, market inefficiencies may exist at times in the small capitalization segment of the market due to a lack of widely available research on these companies. The Portfolio Managers attempt to exploit these market inefficiencies and look for opportunities to invest in companies they believe to be undervalued, such as companies with the following characteristics:

 

■Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

 

■Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify these types of companies, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that the Portfolio Managers believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company’s stock on the basis of the company’s discount to the Portfolio Managers’ estimate of intrinsic value and the Portfolio Managers’ belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst, such as a merger, liquidation, spin off, or management change. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock. The Portfolio Managers also integrate governance factors into the investment process. They seek to invest in companies that have effective and independent boards composed of diverse, and currently active, CEOs and other C-level executives. They look for companies where management and shareholder interests are aligned (often through high ownership of the company by management), with long-term incentive plans and CEO and management compensation and succession plans in place. The Portfolio Managers also seek out companies that have full transparency and disclosure, effective capital deployment strategies and value enhancing merger and acquisition policies. When appropriate, the Portfolio Managers may engage with portfolio companies regarding directors, strategy and financing in an effort to enhance shareholder value. The Portfolio Managers may also engage on financially material environmental and social issues.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continue to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations

 

 

with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of

 

 

the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of one or more broad-based market indices. The indices, which are described in “Descriptions of Indices” in the prospectus, have characteristics relevant to the Fund’s investment strategy.

 

As of May 7, 2010, the Fund became the successor to DJG Small Cap Value Fund L.P., an unregistered limited partnership (“DJG Fund”); DJG Fund was the successor to The DJG Small Cap Value Fund, an unregistered commingled investment account (“DJG Account”). The performance after September 12, 2008 is that of DJG Fund and the performance from July 8, 1997 (the Fund’s commencement of operations) to September 11, 2008 is that of DJG Account. On May 7, 2010, the DJG Fund transferred its assets to the Fund in exchange for the Fund’s Institutional Class shares. The investment policies, objectives, guidelines and restrictions of the Fund are in all material respects equivalent to those of DJG Fund and DJG Account (the “Predecessors”). As a mutual fund registered under the Investment Company Act of 1940, the Fund is subject to certain restrictions under the 1940 Act and the Internal Revenue Code to which the Predecessors were not subject. Had the Predecessors been registered under the 1940 Act and been subject to the provisions of the 1940 Act and the Code, their investment performance may have been adversely affected. The performance information reflects the actual expenses of the Predecessors.

 

The Predecessors did not have distribution policies. The Predecessors were an unregistered limited partnership and an unregistered commingled investment account, did not qualify as regulated investment companies for federal income tax purposes and did not pay dividends or other distributions. As a result of the different tax treatment, we are unable to show the after-tax returns for the Fund prior to May 7, 2010.

 

The following performance prior to May 7, 2010 is that of the Fund’s Predecessors, and that of the Fund’s Institutional Class from May 7, 2010 to January 18, 2019. Because the Institutional Class has higher expenses than Class R6, its performance typically would have been lower than that of Class R6.

 

Returns would have been lower/higher if the Manager had not reimbursed/recouped certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goals, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Growth Index at the time of purchase.

 

The Portfolio Managers employ a research driven approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment. The Portfolio Managers generally seek to identify what they believe to be faster-growing companies with attractive sales growth and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: balance sheet metrics; profit margin profiles; market share and competitive leadership of the company’s products; sales; cash flow and earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other large-capitalization companies.

 

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund seeks to reduce risk by investing across many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy that utilizes a process analyzing macroeconomic and/or security-specific circumstances, and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, and valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger

 

 

companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons

 

 

specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

Prior to April 2, 2012, the Fund had a policy of investing mainly in common stocks of mid- to large-capitalization companies. Its performance prior to that date might have been different if current policies had been in effect.

 

The following performance prior to January 18, 2019 is that of the Fund’s Investor Class. Because Investor Class has higher expenses than Class R6, its performance typically would have been lower than that of Class R6.

 

 

Returns would have been lower/higher if the Manager had not reimbursed/recouped certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Index at the time of purchase.

 

The Portfolio Managers employ a disciplined investment strategy when selecting growth stocks. Using fundamental research and quantitative analysis, they look for what they believe to be fast-growing companies with above-average sales and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: financial condition (such as debt to equity ratio); market share and competitive leadership of the company’s products; earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other mid-cap companies.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Exposure Risk. Securities issued by U.S. entities with substantial foreign operations or holdings, or issued by foreign entities listed on a U.S. exchange, may involve additional risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

Certain issuers, industries and regions may be adversely affected by the impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Value Index at the time of purchase.

 

The Fund’s strategy consists of using a bottom-up, fundamental research driven approach to identify stocks of companies that are trading below the Portfolio Managers’ estimate of their intrinsic value and that they believe have the potential for appreciation over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic worth, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, valuations of certain types of companies are often distorted by market inefficiencies, which can lead to attractive investment opportunities. The Portfolio Managers attempt to exploit recurring market inefficiencies among the following types of companies as the Portfolio Managers believe these types of companies are often misunderstood and mispriced by investors.

 

■Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify potential investment opportunities, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that they believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company based on its discount to their estimate of intrinsic value and their belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst that can be expected to close the value/price gap, such as a merger, restructuring, liquidation, spin-off, major management change, share repurchase, or capital reallocation. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continues to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to

 

instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies. The Fund defines a real estate company as one that derives at least 50% of its revenue from, or has at least 50% of its assets in, real estate.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade securities or below investment grade securities (commonly known as “junk bonds”), provided that, at the time of investment, they are rated at least B by S&P Global Ratings or Moody’s Investors Service, Inc. (or comparably rated by at least one independent credit rating agency) or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund does not normally intend to continue holding securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. The Fund concentrates its assets in the real estate industry. The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care.

 

Some of the REITs and other real estate securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

 

The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, or if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, and valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially

 

interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares

 

may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

As of June 19, 2012, the Fund changed its investment policy to become “non-diversified” under the Investment Company Act of 1940. Its performance prior to this change might have been different if current policies had been in effect.

 

The following performance prior to March 15, 2013, is that of the Fund’s Trust Class. Because Trust Class has higher expenses than Class R6, its performance typically would have been lower than that of Class R6.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 121% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell 2000® Index at the time of initial purchase.

 

The Fund’s strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth, which are underappreciated by the market, durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, change in management and a spin-off or merger. The Portfolio Managers may also invest in anticipation of a catalyst.

 

In analyzing the viability and sustainability of catalysts, the Portfolio Managers evaluate that catalyst’s uniqueness, timing, total potential market and growth potential, as well as assess execution risks, competitive barriers and threats. The Portfolio Managers

 

are also attempting to exploit market inefficiencies that potentially may exist within the small-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. The Portfolio Managers attempt to exploit these market inefficiencies by seeking out and evaluating catalysts which are underappreciated by the market and look for opportunities to invest in companies with the following characteristics:

 

■Underappreciated Growth: Companies with potentially transformative near-term catalysts that are underappreciated by the market, that the Portfolio Managers believe are capable of advancing the development of underlying corporate fundamentals or, in the case of early development-stage companies, initiating a path to revenue and eventually earnings growth

 

■Strengthening Growth: More established companies that are endeavoring to expand their product offerings, broadening operational depth and strengthening top- and bottom-line consistency

 

■Opportunistic Growth: Companies that the Portfolio Managers believe represent an opportunistic valuation play because their potential has yet to be unlocked, they are raising capital or they have fallen out of favor due to what the Portfolio Managers believe is a shorter-term and correctable issue

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading that involves initiating new positions, resizing current positions in response to material developments and in order to maintain an appropriate and attractive risk/reward balance and fully exiting positions in favor of new ideas.

 

The Fund will not change its strategy of normally investing 80% of its net assets in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The Fund defines mid-capitalization companies as those with a total market capitalization of $2 billion and above and large-capitalization companies as those with a total market capitalization of $10 billion and above, both at the time of initial purchase.

 

The Portfolio Manager employs a fundamental research driven approach to stock selection and portfolio construction, with a focus on long term sustainability issues that, in the judgement of the Portfolio Manager, are financially material. This sustainable investment approach seeks to identify high quality, well-positioned companies with leadership that is focused on ESG issues relevant to their business. In doing such, the Portfolio Manager seeks to identify companies with certain practices, including (i) clear and relevant communication regarding management’s understanding, commitment to, and prioritization of, sustainability issues relevant to the business; (ii) identification and disclosure of material sustainability considerations and management objectives (e.g., sustainability-linked goals and targets, including their supply chain, or executive compensation frameworks linked to such goals and targets); and/or (iii) board-level oversight on material sustainability issues. As part of the focus on quality, the Portfolio Manager looks for solid balance sheets, strong management teams with a track record of success, good cash flow, the prospect for above-average earnings growth and the sustainability of those earnings, as well as of the company’s business model, over the long term. The Portfolio Manager seeks to purchase the stock of businesses that he believes to be well positioned and attractively valued. Among companies that meet these criteria, the Portfolio Manager looks for those that show leadership in environmental, social and governance considerations, including safe and equitable workplace practices and constructive community relations.

 

As part of the focus on long-term sustainability, the Portfolio Manager looks for companies that show leadership in their environmental and workplace practices. The Fund seeks to invest in companies that demonstrate ESG policies in the following areas: (i) environmental issues; (ii) employment practices and diversity policies; (iii) community relations; (iv) supply chain issues; (v) product integrity (e.g., safety, quality) and (vi) disclosure and sustainability reporting.

 

Consistent with the Fund’s ESG Criteria, the Portfolio Manager focuses on identifying companies that are responsive to environmental issues, including those that have identified and communicated climate-related risks and opportunities, have identified and communicated net-zero transition plans, have committed to or are transitioning to facilitate global decarbonization and/or the reduction of other greenhouse gas emissions; are agents of favorable change in workplace policies (particularly for women and minorities); are committed to upholding universal human rights standards; and are good corporate citizens. The Portfolio Manager judges companies on their corporate citizenship overall, considering their accomplishments as well as their goals. While these judgments are inevitably subjective, the Portfolio Manager endeavors to avoid companies that derive revenue from gambling or the production of alcohol, tobacco, weapons, nuclear power or private prisons. Please see the Statement of Additional Information for a detailed description of the Fund’s ESG Criteria.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund seeks to reduce risk by investing across many different industries.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security if he believes it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As a sustainable fund, the Fund is required by the federal securities laws to have a policy, which it cannot change without providing investors at least 60 days’ written notice, of investing at least 80% of its net assets in equity securities selected in accordance with its ESG criteria. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding. In practice, the Portfolio Manager intends to hold only securities selected in accordance with the Fund’s ESG Criteria.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

ESG Criteria Risk. The Fund’s application of ESG criteria is designed and utilized to help identify companies that demonstrate the potential to create economic value or reduce risk; however as with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The use of the Fund’s ESG criteria could also affect the Fund’s exposure to certain sectors or

 

industries, and could impact the Fund’s investment performance depending on whether the ESG criteria used are ultimately reflected in the market.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries. These include securities of companies (1) that are traded principally on a stock exchange or over-the-counter in emerging market countries, (2) that are organized under the laws of and have a principal office in emerging market countries, or (3) that derive 50% or more of their total revenues from, and/or have 50% or more of their total assets in, goods produced, sales made, profits generated or services performed in emerging market countries. The Fund considers emerging market countries to be countries included in the MSCI Emerging Markets Index.

 

The Portfolio Manager uses a bottom-up, research-driven securities selection approach focusing on businesses with a recent history of high returns while factoring in economic, legislative and business developments to identify countries and sectors that he believes may be particularly attractive. As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data

 

and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager believes that in-depth, strategic and financial research is the key to identifying undervalued companies and seeks to identify companies with the following characteristics: stock prices undervalued relative to his view of long-term cash flow growth potential; industry leadership; potential for significant improvement in the company’s business; or strong financial characteristics, corporate governance practices, and management track record.

 

The Fund seeks to reduce risk by diversifying among many industries. At times, the Portfolio Manager may emphasize certain sectors that he believes will benefit from market or economic trends. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions.

 

The Fund may invest in companies of any market capitalization. Equity securities in which the Fund may invest include common and preferred stocks, convertible securities, rights and warrants to purchase common stock, depositary receipts and China A-shares using the “connect programs” of local stock exchanges in China, such as the Shanghai-Hong Kong Stock Connect Program, the Shenzhen-Hong Kong Stock Connect Program or other similar programs. The Fund may invest in exchange traded funds (“ETFs”). The Fund may also invest in foreign real estate companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities of issuers in emerging market countries, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Risks of Investments in China A-shares through Stock Connect Programs. There are significant risks inherent in investing in China A-shares through “Connect Programs” of local stock exchanges in China, namely the Shanghai-Hong Kong Stock Connect Program (“Shanghai Connect Program”) and the Shenzhen-Hong Kong Stock Connect Program (“Shenzhen Connect Program”). The Chinese investment and banking systems are materially different in nature from many developed markets, which exposes

 

investors to risks that are different from those in the U.S. The Connect Programs are subject to daily quota limitations, and an investor cannot purchase and sell the same security on the same trading day, which may restrict the Fund’s ability to invest in China A-shares through the Connect Programs and to enter into or exit trades on a timely basis. If either one or both markets involved in a particular Connect Program are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-shares in a timely manner under such Connect Program, which could adversely affect the Fund’s performance. Only certain China A-shares are eligible to be accessed through the Connect Programs. Such securities may lose their eligibility at any time, in which case they could be sold but could no longer be purchased through the Connect Programs.

 

Further regulations or restrictions, such as limitations on redemptions or suspension of trading, may adversely impact the Connect Programs. The future impact of this integration of Chinese and foreign markets is unclear and the actual effect on the market for trading China A-shares with the introduction of large numbers of foreign investors is unknown.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and

 

defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Most economies in the Greater China region are generally considered emerging markets and carry the risks associated with emerging markets, as well as risks particular to the region. Events in any one country within the region may impact other countries in the region or the Greater China region as a whole. The economies, industries, and securities and currency markets of the Greater China region may be adversely affected by slow economic activity worldwide, protectionist trade policies, dependence on exports and international trade, currency devaluations and other currency exchange rate fluctuations, restrictions on monetary repatriation, increasing competition from Asia’s low-cost emerging economies, environmental events and natural disasters that may occur in the Greater China region, and military conflicts either in response to social unrest or with other countries.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Other Investment Company Risk. To the extent the Fund invests in other investment companies, including money market funds and exchange-traded funds (ETFs), its performance will be affected by the performance of those other investment companies. Investments in other investment companies are subject to the risks of the other investment companies’ investments, as well as to the other investment companies’ expenses.

 

An ETF may trade in the secondary market at a price below the value of its underlying portfolio and may not be liquid. An actively managed ETF’s performance will reflect its adviser’s ability to make investment decisions that are suited to achieving the ETF’s investment objectives. A passively managed ETF may not replicate the performance of the index it intends to track.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

Risks of Investing in Variable Interest Entities. For purposes of raising capital offshore on exchanges outside of China, including on U.S. exchanges, many Chinese-based operating companies are structured as entities commonly-referred to as variable interest entities (“VIEs”). In a typical VIE structure, the onshore PRC-based operating company is the VIE and establishes an entity, which is typically offshore in a foreign jurisdiction, such as the Cayman Islands. The offshore entity lists on a foreign exchange and enters into contractual arrangements with the VIE. This structure enables PRC companies in which the PRC government restricts foreign ownership to raise capital from foreign investors. While the offshore entity has no legal equity ownership of the VIE, its contractual arrangements with the VIE permit the offshore entity to consolidate the VIE’s financial statements with its own for FASB accounting purposes and provide for economic exposure to the performance of the underlying onshore PRC operating company. Therefore, an investor in the listed offshore entity, such as the Fund, will have exposure to the onshore PRC-based operating company only through its contractual arrangements with the VIE and has no legal ownership in the VIE. Furthermore, because the offshore entity only has specific rights provided for in these contractual arrangements with the VIE, its abilities to control the activities of the VIE are limited which may engage in activities that negatively impact investment value. While the VIE structure has been widely adopted, it is not formally or legally recognized under PRC law and therefore there is a risk that the PRC government could restrict the effectiveness of such structures or negatively impact the VIE’s contractual arrangements with the listed offshore entity by making them invalid under PRC laws. If these contracts were found to be unenforceable under PRC law, investors in the listed offshore entity, such as the Fund, may suffer significant losses with little or no recourse available. If the PRC government determines that the contractual agreements involving VIE structures do not comply with PRC law and regulations, including those related to restrictions on foreign ownership, it could subject a VIE to numerous sanctions such as penalties, revocation of business and operating licenses, invalidate or terminate contractual arrangements and/or forfeiture or non-recognition of ownership interest.

 

Warrants and Rights Risk. Warrants and rights do not carry with them the right to dividends or voting rights with respect to the securities that they entitle their holder to purchase, and they do not represent any rights in the assets of the issuer. As a result, warrants and rights may be considered more speculative than certain other types of investments. In addition, the value of a warrant or right does not necessarily change with the value of the underlying securities. The Fund could lose the value of a warrant or right if the right to subscribe to additional shares is not exercised prior to the warrant’s or right’s expiration date. The market for warrants and rights may be very limited and there may at times not be a liquid secondary market for warrants and rights.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in income-oriented equity securities that the Portfolio Managers believe will be able to grow their dividends over time. The Fund strives to deliver a total return with lower volatility relative to the Russell 1000® Value index. Additionally, the Fund seeks to generate a current yield that is greater than the average current yield for stocks in the Russell 1000 Value Index. By selecting these types of equity securities, the Fund seeks to dampen the market volatility associated with investing in equity securities.

 

The Fund typically employs a “value” approach in selecting investments. The Portfolio Managers use a bottom-up, research driven approach to identify companies that they believe have the ability to sustain and potentially to grow their free cash flow and are trading at a discount to what the Portfolio Managers believe to be their net present values. The approach involves examining companies for the presence of potential catalysts that will lead to the creation of value, such as regulatory changes, competitive shifts, reaccelerating earnings, and corporate/management restructuring. The Portfolio Managers also utilize various measures of value, including price-to-earnings ratios, price-to-book ratios and discounted free cash flows, among others.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund may invest in real estate investment trusts (“REITs”) and other real estate companies, convertible securities (including convertible preferred stock, which receives preference in the payment of dividends) and common stocks. The Fund defines a real estate company as one that derives at least 50% of its revenue or profits from real estate, or has at least 50% of its assets invested in real estate. The Fund may emphasize the real estate and utilities sectors of the market at any given time and may invest up to 40% of its total assets in each of these sectors. The Fund may invest in convertible securities that are rated below investment grade (commonly known as “junk bonds”) or, if unrated, are determined by the Portfolio Managers to be of comparable quality.

 

The Fund also uses derivatives, including futures contracts on individual securities and indices, and options, including writing (selling) calls against positions in the portfolio (“covered calls”) or writing (selling) puts on individual stocks, in an effort to enhance returns.

 

The Fund may invest in companies of any market capitalization. Although the Fund invests primarily in domestic equity securities, it may also invest in equity securities of foreign companies, including those in emerging markets.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, when other opportunities appear more attractive or when the Portfolio Managers believe the security has grown too large relative to the rest of the portfolio.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities, without providing shareholders at least 60 days’ notice. For this purpose, equity securities include common stock, preferred stock and securities convertible into common or preferred stock. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The Fund’s use of derivative instruments will result in leverage, which amplifies the risks that are associated with these markets. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change

 

based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Derivatives Risk. 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, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. 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. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. 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. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund’s ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual 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.

 

Additional risks associated with certain types of derivatives are discussed below:

 

Futures. Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a fund to close out a position when desired. In the absence of such limits, the liquidity of the futures market depends on participants entering into offsetting transactions rather than taking or making delivery. To the extent a Fund enters into futures contracts requiring physical delivery (e.g., certain commodities contracts), the inability of the Fund to take or make physical delivery can negatively impact performance.

 

Options. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

If the Fund emphasizes the real estate sector, the utilities sector, or both sectors, your investment in the Fund will be linked to the performance of one or both sectors and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

Utility Companies Risk. Utility companies are sensitive to changes in interest rates and other economic conditions, government regulation, uncertainties created by deregulation, environmental protection or energy conservation policies and practices, the level and demand for services, and the cost of technological advances and the possible inability to implement them at opportune times. In addition, securities of utility companies are volatile and may underperform in a sluggish economy.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 55% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be invested in companies with a market capitalization greater than $2.5 billion at the time of purchase.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goals, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Growth Index at the time of purchase.

 

The Portfolio Managers employ a research driven approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment. The Portfolio Managers generally seek to identify what they believe to be faster-growing companies with attractive sales growth and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: balance sheet metrics; profit margin profiles; market share and competitive leadership of the company’s products; sales; cash flow and earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other large-capitalization companies.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may

 

enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund seeks to reduce risk by investing across many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy that utilizes a process analyzing macroeconomic and/or security-specific circumstances, and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt;

 

nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or

 

income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund

 

assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons

 

specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Index at the time of purchase.

 

The Portfolio Managers employ a disciplined investment strategy when selecting growth stocks. Using fundamental research and quantitative analysis, they look for what they believe to be fast-growing companies with above-average sales and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: financial condition (such as debt to equity ratio); market share and competitive leadership of the company’s products; earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other mid-cap companies.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Exposure Risk. Securities issued by U.S. entities with substantial foreign operations or holdings, or issued by foreign entities listed on a U.S. exchange, may involve additional risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Value Index at the time of purchase.

 

The Fund’s strategy consists of using a bottom-up, fundamental research driven approach to identify stocks of companies that are trading below the Portfolio Managers’ estimate of their intrinsic value and that they believe have the potential for appreciation over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic worth, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, valuations of certain types of companies are often distorted by market inefficiencies, which can lead to attractive investment opportunities. The Portfolio Managers attempt to exploit recurring market inefficiencies among the following types of companies as the Portfolio Managers believe these types of companies are often misunderstood and mispriced by investors.

 

■Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify potential investment opportunities, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that they believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company based on its discount to their estimate of intrinsic value and their belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst that can be expected to close the value/price gap, such as a merger, restructuring, liquidation, spin-off, major management change, share repurchase, or capital reallocation. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continues to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to

 

instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies. The Fund defines a real estate company as one that derives at least 50% of its revenue from, or has at least 50% of its assets in, real estate.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade securities or below investment grade securities (commonly known as “junk bonds”), provided that, at the time of investment, they are rated at least B by S&P Global Ratings or Moody’s Investors Service, Inc. (or comparably rated by at least one independent credit rating agency) or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund does not normally intend to continue holding securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. The Fund concentrates its assets in the real estate industry. The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care.

 

Some of the REITs and other real estate securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

 

The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, or if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially

 

interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares

 

may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

As of June 19, 2012, the Fund changed its investment policy to become “non-diversified” under the Investment Company Act of 1940. Its performance prior to this change might have been different if current policies had been in effect.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 121% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell 2000® Index at the time of initial purchase.

 

The Fund’s strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth, which are underappreciated by the market, durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, change in management and a spin-off or merger. The Portfolio Managers may also invest in anticipation of a catalyst.

 

In analyzing the viability and sustainability of catalysts, the Portfolio Managers evaluate that catalyst’s uniqueness, timing, total potential market and growth potential, as well as assess execution risks, competitive barriers and threats. The Portfolio Managers

 

are also attempting to exploit market inefficiencies that potentially may exist within the small-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. The Portfolio Managers attempt to exploit these market inefficiencies by seeking out and evaluating catalysts which are underappreciated by the market and look for opportunities to invest in companies with the following characteristics:

 

■Underappreciated Growth: Companies with potentially transformative near-term catalysts that are underappreciated by the market, that the Portfolio Managers believe are capable of advancing the development of underlying corporate fundamentals or, in the case of early development-stage companies, initiating a path to revenue and eventually earnings growth

 

■Strengthening Growth: More established companies that are endeavoring to expand their product offerings, broadening operational depth and strengthening top- and bottom-line consistency

 

■Opportunistic Growth: Companies that the Portfolio Managers believe represent an opportunistic valuation play because their potential has yet to be unlocked, they are raising capital or they have fallen out of favor due to what the Portfolio Managers believe is a shorter-term and correctable issue

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading that involves initiating new positions, resizing current positions in response to material developments and in order to maintain an appropriate and attractive risk/reward balance and fully exiting positions in favor of new ideas.

 

The Fund will not change its strategy of normally investing 80% of its net assets in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 14% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund seeks to invest primarily in common stocks of mid- to large-capitalization companies that meet the Fund’s quality oriented financial and ESG criteria. The Fund defines mid-capitalization companies as those with a total market capitalization of $2 billion and above and large-capitalization companies as those with a total market capitalization of $10 billion and above, both at the time of initial purchase.

 

The Portfolio Manager employs a fundamental research driven approach to stock selection and portfolio construction, with a focus on long term sustainability issues that, in the judgement of the Portfolio Manager, are financially material. This sustainable investment approach seeks to identify high quality, well-positioned companies with leadership that is focused on ESG issues relevant to their business. In doing such, the Portfolio Manager seeks to identify companies with certain practices, including (i) clear and relevant communication regarding management’s understanding, commitment to, and prioritization of, sustainability issues relevant to the business; (ii) identification and disclosure of material sustainability considerations and management objectives (e.g., sustainability-linked goals and targets, including their supply chain, or executive compensation frameworks linked to such goals and targets); and/or (iii) board-level oversight on material sustainability issues. As part of the focus on quality, the Portfolio Manager looks for solid balance sheets, strong management teams with a track record of success, good cash flow, the prospect for above-average earnings growth and the sustainability of those earnings, as well as of the company’s business model, over the long term. The Portfolio Manager seeks to purchase the stock of businesses that he believes to be well positioned and attractively valued. Among companies that meet these criteria, the Portfolio Manager looks for those that show leadership in environmental, social and governance considerations, including safe and equitable workplace practices and constructive community relations.

 

As part of the focus on long-term sustainability, the Portfolio Manager looks for companies that show leadership in their environmental and workplace practices. The Fund seeks to invest in companies that demonstrate ESG policies in the following areas: (i) environmental issues; (ii) employment practices and diversity policies; (iii) community relations; (iv) supply chain issues; (v) product integrity (e.g., safety, quality) and (vi) disclosure and sustainability reporting.

 

Consistent with the Fund’s ESG Criteria, the Portfolio Manager focuses on identifying companies that are responsive to environmental issues, including those that have identified and communicated climate-related risks and opportunities, have identified and communicated net-zero transition plans, have committed to or are transitioning to facilitate global decarbonization and/or the reduction of other greenhouse gas emissions; are agents of favorable change in workplace policies (particularly for women and minorities); are committed to upholding universal human rights standards; and are good corporate citizens. The Portfolio Manager judges companies on their corporate citizenship overall, considering their accomplishments as well as their goals. While these judgments are inevitably subjective, the Portfolio Manager endeavors to avoid companies that derive revenue from gambling or the production of alcohol, tobacco, weapons, nuclear power or private prisons. Please see the Statement of Additional Information for a detailed description of the Fund’s ESG Criteria.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund seeks to reduce risk by investing across many different industries.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security if he believes it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As a sustainable fund, the Fund is required by the federal securities laws to have a policy, which it cannot change without providing investors at least 60 days’ written notice, of investing at least 80% of its net assets in equity securities selected in accordance with its ESG criteria. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding. In practice, the Portfolio Manager intends to hold only securities selected in accordance with the Fund’s ESG Criteria.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

ESG Criteria Risk. The Fund’s application of ESG criteria is designed and utilized to help identify companies that demonstrate the potential to create economic value or reduce risk; however as with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The use of the Fund’s ESG criteria could also affect the Fund’s exposure to certain sectors or

 

industries, and could impact the Fund’s investment performance depending on whether the ESG criteria used are ultimately reflected in the market.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations

 

with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio, consisting mainly of common stocks of companies of any size that are selected using a fundamental, research driven approach.

 

Under normal market conditions, the Fund typically holds a limited number of stocks of U.S. and non-U.S. companies, including companies in emerging markets. Because of this, the Fund may at times be substantially over- and under-weighted in certain economic sectors.

 

The Portfolio Managers, with the assistance of Neuberger Berman research analysts, look for what they believe to be undervalued companies. Factors in identifying these firms may include depressed valuations, a history of above-average returns, an established market niche, and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with investing in a smaller number of stocks.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund may invest in depositary receipts.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target valuation, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other

 

developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues

 

and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the

 

Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of

 

a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies of any size, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and regions around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and

 

geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than

 

securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management

 

team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goals, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Growth Index at the time of purchase.

 

The Portfolio Managers employ a research driven approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment. The Portfolio Managers generally seek to identify what they believe to be faster-growing companies with attractive sales growth and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: balance sheet metrics; profit margin profiles; market share and competitive leadership of the company’s products; sales; cash flow and earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other large-capitalization companies.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund seeks to reduce risk by investing across many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy that utilizes a process analyzing macroeconomic and/or security-specific circumstances, and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign

 

markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of

 

the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic

 

fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons

 

specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

Prior to April 2, 2012, the Fund had a policy of investing mainly in common stocks of mid- to large-capitalization companies. Its performance prior to that date might have been different if current policies had been in effect.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Index at the time of purchase.

 

The Portfolio Managers employ a disciplined investment strategy when selecting growth stocks. Using fundamental research and quantitative analysis, they look for what they believe to be fast-growing companies with above-average sales and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: financial condition (such as debt to equity ratio); market share and competitive leadership of the company’s products; earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other mid-cap companies.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Exposure Risk. Securities issued by U.S. entities with substantial foreign operations or holdings, or issued by foreign entities listed on a U.S. exchange, may involve additional risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 22% of the average value of its portfolio.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Value Index at the time of purchase.

 

The Fund’s strategy consists of using a bottom-up, fundamental research driven approach to identify stocks of companies that are trading below the Portfolio Managers’ estimate of their intrinsic value and that they believe have the potential for appreciation over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic worth, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, valuations of certain types of companies are often distorted by market inefficiencies, which can lead to attractive investment opportunities. The Portfolio Managers attempt to exploit recurring market inefficiencies among the following types of companies as the Portfolio Managers believe these types of companies are often misunderstood and mispriced by investors.

 

■Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify potential investment opportunities, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that they believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company based on its discount to their estimate of intrinsic value and their belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst that can be expected to close the value/price gap, such as a merger, restructuring, liquidation, spin-off, major management change, share repurchase, or capital reallocation. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continues to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell 2000® Index at the time of initial purchase.

 

The Fund’s strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth, which are underappreciated by the market, durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, change in management and a spin-off or merger. The Portfolio Managers may also invest in anticipation of a catalyst.

 

In analyzing the viability and sustainability of catalysts, the Portfolio Managers evaluate that catalyst’s uniqueness, timing, total potential market and growth potential, as well as assess execution risks, competitive barriers and threats. The Portfolio Managers

 

are also attempting to exploit market inefficiencies that potentially may exist within the small-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. The Portfolio Managers attempt to exploit these market inefficiencies by seeking out and evaluating catalysts which are underappreciated by the market and look for opportunities to invest in companies with the following characteristics:

 

■Underappreciated Growth: Companies with potentially transformative near-term catalysts that are underappreciated by the market, that the Portfolio Managers believe are capable of advancing the development of underlying corporate fundamentals or, in the case of early development-stage companies, initiating a path to revenue and eventually earnings growth

 

■Strengthening Growth: More established companies that are endeavoring to expand their product offerings, broadening operational depth and strengthening top- and bottom-line consistency

 

■Opportunistic Growth: Companies that the Portfolio Managers believe represent an opportunistic valuation play because their potential has yet to be unlocked, they are raising capital or they have fallen out of favor due to what the Portfolio Managers believe is a shorter-term and correctable issue

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading that involves initiating new positions, resizing current positions in response to material developments and in order to maintain an appropriate and attractive risk/reward balance and fully exiting positions in favor of new ideas.

 

The Fund will not change its strategy of normally investing 80% of its net assets in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund seeks to invest primarily in common stocks of mid- to large-capitalization companies that meet the Fund’s quality oriented financial and ESG criteria. The Fund defines mid-capitalization companies as those with a total market capitalization of $2 billion and above and large-capitalization companies as those with a total market capitalization of $10 billion and above, both at the time of initial purchase.

 

The Portfolio Manager employs a fundamental research driven approach to stock selection and portfolio construction, with a focus on long term sustainability issues that, in the judgement of the Portfolio Manager, are financially material. This sustainable investment approach seeks to identify high quality, well-positioned companies with leadership that is focused on ESG issues relevant to their business. In doing such, the Portfolio Manager seeks to identify companies with certain practices, including (i) clear and relevant communication regarding management’s understanding, commitment to, and prioritization of, sustainability issues relevant to the business; (ii) identification and disclosure of material sustainability considerations and management objectives (e.g., sustainability-linked goals and targets, including their supply chain, or executive compensation frameworks linked to such goals and targets); and/or (iii) board-level oversight on material sustainability issues. As part of the focus on quality, the Portfolio Manager looks for solid balance sheets, strong management teams with a track record of success, good cash flow, the prospect for above-average earnings growth and the sustainability of those earnings, as well as of the company’s business model, over the long term. The Portfolio Manager seeks to purchase the stock of businesses that he believes to be well positioned and attractively valued. Among companies that meet these criteria, the Portfolio Manager looks for those that show leadership in environmental, social and governance considerations, including safe and equitable workplace practices and constructive community relations.

 

As part of the focus on long-term sustainability, the Portfolio Manager looks for companies that show leadership in their environmental and workplace practices. The Fund seeks to invest in companies that demonstrate ESG policies in the following areas: (i) environmental issues; (ii) employment practices and diversity policies; (iii) community relations; (iv) supply chain issues; (v) product integrity (e.g., safety, quality) and (vi) disclosure and sustainability reporting.

 

Consistent with the Fund’s ESG Criteria, the Portfolio Manager focuses on identifying companies that are responsive to environmental issues, including those that have identified and communicated climate-related risks and opportunities, have identified and communicated net-zero transition plans, have committed to or are transitioning to facilitate global decarbonization and/or the reduction of other greenhouse gas emissions; are agents of favorable change in workplace policies (particularly for women and minorities); are committed to upholding universal human rights standards; and are good corporate citizens. The Portfolio Manager judges companies on their corporate citizenship overall, considering their accomplishments as well as their goals. While these judgments are inevitably subjective, the Portfolio Manager endeavors to avoid companies that derive revenue from gambling or the production of alcohol, tobacco, weapons, nuclear power or private prisons. Please see the Statement of Additional Information for a detailed description of the Fund’s ESG Criteria.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund seeks to reduce risk by investing across many different industries.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security if he believes it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As a sustainable fund, the Fund is required by the federal securities laws to have a policy, which it cannot change without providing investors at least 60 days’ written notice, of investing at least 80% of its net assets in equity securities selected in accordance with its ESG criteria. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding. In practice, the Portfolio Manager intends to hold only securities selected in accordance with the Fund’s ESG Criteria.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

ESG Criteria Risk. The Fund’s application of ESG criteria is designed and utilized to help identify companies that demonstrate the potential to create economic value or reduce risk; however as with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The use of the Fund’s ESG criteria could also affect the Fund’s exposure to certain sectors or

 

industries, and could impact the Fund’s investment performance depending on whether the ESG criteria used are ultimately reflected in the market.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio, consisting mainly of common stocks of companies of any size that are selected using a fundamental, research driven approach.

 

Under normal market conditions, the Fund typically holds a limited number of stocks of U.S. and non-U.S. companies, including companies in emerging markets. Because of this, the Fund may at times be substantially over- and under-weighted in certain economic sectors.

 

The Portfolio Managers, with the assistance of Neuberger Berman research analysts, look for what they believe to be undervalued companies. Factors in identifying these firms may include depressed valuations, a history of above-average returns, an established market niche, and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with investing in a smaller number of stocks.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund may invest in depositary receipts.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target valuation, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Depositary Receipts Risk. Depositary receipts are certificates issued by a financial institution evidencing ownership of underlying foreign securities. Depositary receipts involve many of the same risks of investing directly in the underlying foreign securities. Depositary receipts are subject to the risk of fluctuation in the currency exchange rate if, as is often the case, the underlying foreign securities are denominated in foreign currency, and there may be an imperfect correlation between the market value of depositary receipts and the underlying foreign securities.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure,

 

governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and

 

unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates.

 

Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to

 

instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history

 

of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

No risk management program can eliminate the Fund’s exposure to adverse events; at best, it may 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies of any size, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and regions around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and

 

geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than

 

securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management

 

team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goals, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Growth Index at the time of purchase.

 

The Portfolio Managers employ a research driven approach to stock selection, with a long term perspective that combines both quantitative analysis and qualitative judgment. The Portfolio Managers generally seek to identify what they believe to be faster-growing companies with attractive sales growth and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: balance sheet metrics; profit margin profiles; market share and competitive leadership of the company’s products; sales; cash flow and earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other large-capitalization companies.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as

 

certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption. The Fund may also invest in private companies, including companies that have not yet issued securities publicly in an initial public offering.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Fund seeks to reduce risk by investing across many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy that utilizes a process analyzing macroeconomic and/or security-specific circumstances, and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory

 

withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities

 

underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Private Companies and Pre-IPO Investments Risk. Investments in private companies, including companies that have not yet issued securities publicly in an initial public offering (“IPO”) (“pre-IPO shares”), involve greater risks than investments in securities of companies that have traded publicly on an exchange for extended periods of time. Investments in these companies are generally less liquid than investments in securities issued by public companies and may be difficult for the Fund to value. Compared to public companies, private companies may have a more limited management group and limited operating histories with narrower, less established product lines and smaller market shares, which may cause them to be more vulnerable to competitors’ actions, market conditions and consumer sentiment with respect to their products or services, as well as general economic downturns. In addition, private companies may have limited financial resources and may be unable to meet their obligations. The Fund may only have limited access to a private company’s actual financial results and there is no assurance that the information obtained by the Fund is reliable. These companies may not ever issue shares in an IPO and a liquid market for their shares may never develop, which could adversely affect the Fund’s liquidity. If the company does issue shares in an IPO, IPOs are risky and volatile and may cause the value of the Fund’s investment to decrease significantly. Moreover, because securities issued by private companies are generally not freely or publicly tradable, the Fund may not have the opportunity to purchase, or the ability to sell, these securities in the amounts, or at the prices, the Fund desires.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the

 

pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from

 

deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 82% of the average value of its portfolio.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons

 

specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 58% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Index at the time of purchase.

 

The Portfolio Managers employ a disciplined investment strategy when selecting growth stocks. Using fundamental research and quantitative analysis, they look for what they believe to be fast-growing companies with above-average sales and competitive returns on equity relative to their peers. In doing so, the Portfolio Managers analyze such factors as: financial condition (such as debt to equity ratio); market share and competitive leadership of the company’s products; earnings growth relative to competitors; and market valuation in comparison to a stock’s own historical norms and the stocks of other mid-cap companies.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Exposure Risk. Securities issued by U.S. entities with substantial foreign operations or holdings, or issued by foreign entities listed on a U.S. exchange, may involve additional risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of mid-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell Midcap® Value Index at the time of purchase.

 

The Fund’s strategy consists of using a bottom-up, fundamental research driven approach to identify stocks of companies that are trading below the Portfolio Managers’ estimate of their intrinsic value and that they believe have the potential for appreciation over time. The Portfolio Managers’ estimate of a company’s intrinsic value represents their view of the company’s true, long-term economic worth, the market’s view of which may be currently distorted by market inefficiencies. The intrinsic value estimate represents what the Portfolio Managers believe a company could be worth if it is acquired, if its profitability returns to its long-term average level, or if its valuation moves in line with those companies that the Portfolio Managers see as its publicly traded peers.

 

The Portfolio Managers believe that while markets are often efficient, valuations of certain types of companies are often distorted by market inefficiencies, which can lead to attractive investment opportunities. The Portfolio Managers attempt to exploit recurring market inefficiencies among the following types of companies as the Portfolio Managers believe these types of companies are often misunderstood and mispriced by investors.

 

■Complex Companies: These companies typically have multiple lines of business that are in different industries or sectors and/or that have different growth rates and profitability characteristics.

 

■Cyclical Companies: These companies typically have ebbs and flows in their business depending on demand patterns for their products, the length of product cycles, or other transient factors.

 

■Companies in a Period of Interrupted Growth: Typically, these are companies in attractive, high growth markets that have suffered what the Portfolio Managers believe is a temporary setback and/or are in transition to a more mature, lower growth business model that focuses more on current earnings than on rapid growth.

 

In seeking to identify potential investment opportunities, the Portfolio Managers perform an initial screening to identify those companies that have stock prices that are trailing the performance of the overall market and that they believe are attractive relative to current cash flows. Next, the Portfolio Managers establish an estimate of a company’s intrinsic value. The Portfolio Managers will invest in a company based on its discount to their estimate of intrinsic value and their belief in its potential for appreciation over time. In addition, the Portfolio Managers may invest in anticipation of a catalyst that can be expected to close the value/price gap, such as a merger, restructuring, liquidation, spin-off, major management change, share repurchase, or capital reallocation. The Portfolio Managers will typically visit a company and interview its management team to help understand management’s incentives (such as equity ownership in the company and compensation plans), the merits of its strategic plan, and other factors that have the potential to increase the value of the company’s stock.

 

The Portfolio Managers establish an intrinsic value for a company’s stock when it is purchased and then continues to evaluate the company’s stock price versus their estimate of its intrinsic value to determine whether to maintain, add to, reduce or eliminate the position. The Portfolio Managers typically reduce or eliminate a position in a company’s stock if the stock’s price appreciates and the company’s discount to their estimate of its intrinsic value narrows. The Portfolio Managers’ decision to reduce or eliminate a position in a particular stock may also be driven by their belief that another company’s stock has a wider discount to their estimate of its intrinsic value. Changes in a company’s management or corporate strategy, or the failure of a company to perform as expected, may also cause the Portfolio Managers to reduce or eliminate a position in that company’s stock.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund may invest in restricted securities, including private placements, which are securities that are subject to legal restrictions on their sale and may not be sold to the public unless registered under the applicable securities law or pursuant to an applicable exemption.

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe may benefit from market or economic trends.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of mid-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to

 

instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid-Cap Companies Risk. At times, mid-cap companies may be out of favor with investors. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. As a result of the absence of a public trading market, the prices of these securities may be more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. Transaction costs may be higher for these securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value or intrinsic value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of the Russell 2000® Index at the time of initial purchase.

 

The Fund’s strategy utilizes a qualitative, bottom-up research driven approach to identify companies that the Portfolio Managers believe have catalysts for growth, which are underappreciated by the market, durable and potentially unique business models and/or proficient management capable of advancing the development of and/or strengthening of sustainable and consistent revenue growth, cash flow growth, earnings growth and/or overall balance sheet strength. Such catalysts may include a new technology, product or service, a regulatory update, change in management and a spin-off or merger. The Portfolio Managers may also invest in anticipation of a catalyst.

 

In analyzing the viability and sustainability of catalysts, the Portfolio Managers evaluate that catalyst’s uniqueness, timing, total potential market and growth potential, as well as assess execution risks, competitive barriers and threats. The Portfolio Managers are also attempting to exploit market inefficiencies that potentially may exist within the small-capitalization market, due to the number of companies that comprise the investable universe and the limited amount of available research that exists for some of those companies. The Portfolio Managers attempt to exploit these market inefficiencies by seeking out and evaluating catalysts which are underappreciated by the market and look for opportunities to invest in companies with the following characteristics:

 

■Underappreciated Growth: Companies with potentially transformative near-term catalysts that are underappreciated by the market, that the Portfolio Managers believe are capable of advancing the development of underlying corporate fundamentals or, in the case of early development-stage companies, initiating a path to revenue and eventually earnings growth

 

■Strengthening Growth: More established companies that are endeavoring to expand their product offerings, broadening operational depth and strengthening top- and bottom-line consistency

 

■Opportunistic Growth: Companies that the Portfolio Managers believe represent an opportunistic valuation play because their potential has yet to be unlocked, they are raising capital or they have fallen out of favor due to what the Portfolio Managers believe is a shorter-term and correctable issue

 

The Fund seeks to reduce risk by diversifying among many companies, sectors and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

The Portfolio Managers constantly monitor their holdings and are focused on maintaining what they believe is an appropriate and attractive risk/reward balance with a disciplined sell process that acts quickly and dispassionately to address both positive and negative outcomes. A position is typically trimmed or exited for the following reasons: to harvest gains from significant short-term price appreciation, the positive realization of a catalyst, the achievement of a price target or elevated valuations, identification of a better idea, to minimize potential risks, to address an absence of near-term drivers or catalysts, a significant deterioration of fundamentals, a change in management or operating strategy or the failure of a catalyst to develop.

 

In an effort to achieve its goal, the Fund may engage in active and frequent trading that involves initiating new positions, resizing current positions in response to material developments and in order to maintain an appropriate and attractive risk/reward balance and fully exiting positions in favor of new ideas.

 

The Fund will not change its strategy of normally investing 80% of its net assets in small-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the

 

securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund seeks to invest primarily in common stocks of mid- to large-capitalization companies that meet the Fund’s quality oriented financial and ESG criteria. The Fund defines mid-capitalization companies as those with a total market capitalization of $2 billion and above and large-capitalization companies as those with a total market capitalization of $10 billion and above, both at the time of initial purchase.

 

The Portfolio Manager employs a fundamental research driven approach to stock selection and portfolio construction, with a focus on long term sustainability issues that, in the judgement of the Portfolio Manager, are financially material. This sustainable investment approach seeks to identify high quality, well-positioned companies with leadership that is focused on ESG issues relevant to their business. In doing such, the Portfolio Manager seeks to identify companies with certain practices, including (i) clear and relevant communication regarding management’s understanding, commitment to, and prioritization of, sustainability issues relevant to the business; (ii) identification and disclosure of material sustainability considerations and management objectives (e.g., sustainability-linked goals and targets, including their supply chain, or executive compensation frameworks linked to such goals and targets); and/or (iii) board-level oversight on material sustainability issues. As part of the focus on quality, the Portfolio Manager looks for solid balance sheets, strong management teams with a track record of success, good cash flow, the prospect for above-average earnings growth and the sustainability of those earnings, as well as of the company’s business model, over the long term. The Portfolio Manager seeks to purchase the stock of businesses that he believes to be well positioned and attractively valued. Among companies that meet these criteria, the Portfolio Manager looks for those that show leadership in environmental, social and governance considerations, including safe and equitable workplace practices and constructive community relations.

 

As part of the focus on long-term sustainability, the Portfolio Manager looks for companies that show leadership in their environmental and workplace practices. The Fund seeks to invest in companies that demonstrate ESG policies in the following areas: (i) environmental issues; (ii) employment practices and diversity policies; (iii) community relations; (iv) supply chain issues; (v) product integrity (e.g., safety, quality) and (vi) disclosure and sustainability reporting.

 

Consistent with the Fund’s ESG Criteria, the Portfolio Manager focuses on identifying companies that are responsive to environmental issues, including those that have identified and communicated climate-related risks and opportunities, have identified and communicated net-zero transition plans, have committed to or are transitioning to facilitate global decarbonization and/or the reduction of other greenhouse gas emissions; are agents of favorable change in workplace policies (particularly for women and minorities); are committed to upholding universal human rights standards; and are good corporate citizens. The Portfolio Manager judges companies on their corporate citizenship overall, considering their accomplishments as well as their goals. While these judgments are inevitably subjective, the Portfolio Manager endeavors to avoid companies that derive revenue from gambling or the production of alcohol, tobacco, weapons, nuclear power or private prisons. Please see the Statement of Additional Information for a detailed description of the Fund’s ESG Criteria.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund seeks to reduce risk by investing across many different industries.

 

The Portfolio Manager follows a disciplined selling strategy and may sell a security if he believes it is unattractively valued, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

As a sustainable fund, the Fund is required by the federal securities laws to have a policy, which it cannot change without providing investors at least 60 days’ written notice, of investing at least 80% of its net assets in equity securities selected in accordance with its ESG criteria. The 80% test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding. In practice, the Portfolio Manager intends to hold only securities selected in accordance with the Fund’s ESG Criteria.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

ESG Criteria Risk. The Fund’s application of ESG criteria is designed and utilized to help identify companies that demonstrate the potential to create economic value or reduce risk; however as with the use of any investment criteria in selecting a portfolio, there is no guarantee that the criteria used by the Fund will result in the selection of issuers that will outperform other issuers, or help reduce risk in the portfolio. The use of the Fund’s ESG criteria could also affect the Fund’s exposure to certain sectors or

 

industries, and could impact the Fund’s investment performance depending on whether the ESG criteria used are ultimately reflected in the market.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad. Under normal circumstances, at least 80% of the Fund’s net assets, plus the amount of any borrowings for investment purposes, will be invested in companies with a market capitalization greater than $2.5 billion at the time of purchase.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and sectors around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to remain well-diversified across countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 37% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies. The Fund defines a real estate company as one that derives at least 50% of its revenue from, or has at least 50% of its assets in, real estate.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade securities or below investment grade securities (commonly known as “junk bonds”), provided that, at the time of investment, they are rated at least B by S&P Global Ratings or Moody’s Investors Service, Inc. (or comparably rated by at least one independent credit rating agency) or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund does not normally intend to continue holding securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as

 

certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. The Fund concentrates its assets in the real estate industry. The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care.

 

Some of the REITs and other real estate securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

 

The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, or if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause

 

credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary and in “Sales Charge Reductions and Waivers” on page 23 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and

 

the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign

 

markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The returns in the bar chart do not reflect any applicable sales charges. If sales charges were reflected, returns would be lower than those shown. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Description of Index” in the prospectus, has characteristics relevant to the Fund’s investment strategy. Unlike the returns in the bar chart, the returns in the table reflect the maximum applicable sales charges.

 

The following performance is that of the Fund’s Investor Class, which is not offered through this prospectus. In the table next to the bar chart, the performance information of Investor Class has been adjusted to reflect the maximum sales charges applicable to Class A and Class C shares, but has not been adjusted to take into account differences in class specific operating expenses (such as Rule 12b-1 fees). Class A and Class C would have substantially similar performance to Investor Class because the classes are invested in the same portfolio of securities. Because Investor Class has lower expenses than Class A and Class C, its performance typically would have been better than that of Class A and Class C.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in income-oriented equity securities that the Portfolio Managers believe will be able to grow their dividends over time. The Fund strives to deliver a total return with lower volatility relative to the Russell 1000® Value index. Additionally, the Fund seeks to generate a current yield that is greater than the average current yield for stocks in the Russell 1000 Value Index. By selecting these types of equity securities, the Fund seeks to dampen the market volatility associated with investing in equity securities.

 

The Fund typically employs a “value” approach in selecting investments. The Portfolio Managers use a bottom-up, research driven approach to identify companies that they believe have the ability to sustain and potentially to grow their free cash flow and are trading at a discount to what the Portfolio Managers believe to be their net present values. The approach involves examining companies for the presence of potential catalysts that will lead to the creation of value, such as regulatory changes, competitive shifts, reaccelerating earnings, and corporate/management restructuring. The Portfolio Managers also utilize various measures of value, including price-to-earnings ratios, price-to-book ratios and discounted free cash flows, among others.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may

 

enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund may invest in real estate investment trusts (“REITs”) and other real estate companies, convertible securities (including convertible preferred stock, which receives preference in the payment of dividends) and common stocks. The Fund defines a real estate company as one that derives at least 50% of its revenue or profits from real estate, or has at least 50% of its assets invested in real estate. The Fund may emphasize the real estate and utilities sectors of the market at any given time and may invest up to 40% of its total assets in each of these sectors. The Fund may invest in convertible securities that are rated below investment grade (commonly known as “junk bonds”) or, if unrated, are determined by the Portfolio Managers to be of comparable quality.

 

The Fund also uses derivatives, including futures contracts on individual securities and indices, and options, including writing (selling) calls against positions in the portfolio (“covered calls”) or writing (selling) puts on individual stocks, in an effort to enhance returns.

 

The Fund may invest in companies of any market capitalization. Although the Fund invests primarily in domestic equity securities, it may also invest in equity securities of foreign companies, including those in emerging markets.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, when other opportunities appear more attractive or when the Portfolio Managers believe the security has grown too large relative to the rest of the portfolio.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities, without providing shareholders at least 60 days’ notice. For this purpose, equity securities include common stock, preferred stock and securities convertible into common or preferred stock. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The Fund’s use of derivative instruments will result in leverage, which amplifies the risks that are associated with these markets. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks when the underlying stock’s price is high relative to the conversion price

 

and is subject to the market risks of debt securities when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk -- that is, the value of convertible securities will move in the direction opposite to movements in interest rates; they are subject to the risk that the issuer will not be able to pay interest or dividends when due; and their market value may change based on changes in the issuer’s credit rating or the market’s perception of the issuer’s creditworthiness. Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities (commonly known as “junk bonds”). Lower-rated debt securities may fluctuate more widely in price and yield than investment grade debt securities and may fall in price during times when the economy is weak or is expected to become weak. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Derivatives Risk. 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, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. 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. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. 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. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund’s ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual 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.

 

Additional risks associated with certain types of derivatives are discussed below:

 

Futures. Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a fund to close out a position when desired. In the absence of such limits, the liquidity of the futures market depends on participants entering into offsetting transactions rather than taking or making delivery. To the extent a Fund enters into futures contracts requiring physical delivery (e.g., certain commodities contracts), the inability of the Fund to take or make physical delivery can negatively impact performance.

 

Options. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the

 

exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as income-oriented equity securities that pay dividends, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the

 

Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

If the Fund emphasizes the real estate sector, the utilities sector, or both sectors, your investment in the Fund will be linked to the performance of one or both sectors and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

Utility Companies Risk. Utility companies are sensitive to changes in interest rates and other economic conditions, government regulation, uncertainties created by deregulation, environmental protection or energy conservation policies and practices, the level and demand for services, and the cost of technological advances and the possible inability to implement them at opportune times. In addition, securities of utility companies are volatile and may underperform in a sluggish economy.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

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 operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 12% of the average value of its portfolio.

The expense example can help you compare costs among mutual funds. The example assumes that you invested $10,000 for the periods shown, that you redeemed all of your shares at the end of those periods, that the Fund earned a hypothetical 5% total return each year, and that the Fund’s expenses were those in the table. Actual performance and expenses may be higher or lower.

 
Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of small-capitalization companies, which it defines as those with a total market capitalization within the market capitalization range of companies in the Russell 2000® Index at the time of initial purchase. The market capitalization of the companies in the Fund’s portfolio and the Russell 2000 Index changes over time and the Fund may continue to hold or add to a position in a company after its market capitalization has moved outside the range of the Russell 2000 Index.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors that they believe will benefit from market or economic trends.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

The Portfolio Managers generally look for what they believe to be undervalued companies whose current market shares and balance sheets are strong. In addition, the Portfolio Managers tend to focus on companies whose financial strength is largely based on existing business lines rather than on projected growth. Factors in identifying these firms may include: a history of above-average returns; an established market niche; circumstances that would make it difficult for new competitors to enter the market; the ability to finance their own growth; and a belief that the company has sound future business prospects. This approach is

 

designed to let the Fund benefit from potential increases in stock prices, while endeavoring to limit the risks typically associated with small-cap stocks.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other

 

developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Small- and Mid-Cap Companies Risk. At times, small- and mid-cap companies may be out of favor with investors. Compared to larger companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions. To the extent the Fund holds securities of mid-cap companies, the Fund will be subject to their risks.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

The performance prior to January 11, 2022 is that of the Fund’s Investor Class, which is not offered through this prospectus. Class E would have substantially similar performance to Investor Class because the classes invest in the same portfolio of securities. Because Investor Class has higher expenses than Class E, its performance would have been lower than that of Class E.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests mainly in common stocks of foreign companies of any size, including companies in developed and emerging markets. The Fund defines a foreign company as one that is organized outside of the United States and conducts the majority of its business abroad.

 

In picking stocks, the Portfolio Managers look for what they believe to be well-managed and profitable companies that show growth potential and whose stock prices are undervalued. Factors in identifying these firms may include strong fundamentals, such as attractive cash flows and balance sheets, as well as prices that are attractive in light of projected returns. The Portfolio Managers also consider the outlooks for various countries and regions around the world, examining economic, market, social, and political conditions.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as

 

certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund seeks to reduce risk by diversifying among many companies and industries. Although the Fund has the flexibility to invest a significant portion of its assets in one country or region, it generally intends to invest across a broad range of countries and geographical regions. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe offers a better risk/reward opportunity.

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in equity securities, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in international stock markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign and Emerging Market Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may 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. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed market countries than in countries with more developed markets. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. Suspensions may last for significant periods of time, during which trading in the securities and in instruments that reference the securities, such as derivative instruments, may be halted. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

From time to time, based on market or economic conditions, the Fund may invest a significant portion of its assets in one country or geographic region. If the Fund does so, there is a greater risk that economic, political, regulatory, diplomatic, social and environmental conditions in that particular country or geographic region may have a significant impact on the Fund’s performance and that the Fund’s performance will be more volatile than the performance of more geographically diversified funds.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. 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 attempts to lessen the risk of such losses by seeking growth stocks that sell at what the adviser believes are attractive prices. If the adviser is incorrect in its assessment of a stock’s value, this may negatively impact the Fund. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Liquidity Risk. From time to time, the trading market for a particular investment in which the Fund invests, or a particular type of instrument in which the Fund is invested, may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly. Additionally, market closures due to holidays or other factors may render a security or group of securities (e.g., securities tied to a particular country or geographic region) illiquid for a period of time. 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 securities or other investments 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.

 

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially

 

sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

The performance prior to January 11, 2022 is that of the Fund’s Institutional Class, which is not offered through this prospectus. Class E would have substantially similar performance to Institutional Class because the classes invest in the same portfolio of securities. Because Institutional Class has higher expenses than Class E, its performance typically would have been lower than that of Class E.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities of large-capitalization companies, which it defines as those with a market capitalization within the market capitalization range of the Russell 1000® Value Index at the time of purchase.

 

The Portfolio Managers look for what they believe to be well-managed companies whose stock prices are undervalued. The Portfolio Managers seek to identify companies with catalysts that they believe have the potential to improve the companies’ earnings from depressed levels. Such catalysts may include: management changes, restructurings, new products, new services, or new markets. The Portfolio Managers may also look for other characteristics in a company, such as a strong market position relative to competitors, a high level of stock ownership among management, and a recent sharp decline in stock price that appears to be the result of a short-term market overreaction to negative news.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies. The Fund may also invest in real estate investment trusts (“REITs”).

 

The Fund seeks to reduce risk by diversifying among many companies and industries. At times, the Portfolio Managers may emphasize certain sectors or industries that they believe are undervalued relative to their historical valuations.

 

The Fund may also use options, including, but not limited to, buying and selling (writing) put and call options on individual stocks, to attempt to enhance returns. The Fund will only sell (write) call options on individual stocks if it simultaneously holds an equivalent position in the stock underlying the option (“covered call option”).

 

The Portfolio Managers follow a disciplined selling strategy and may sell a security when it reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive. In an effort to achieve its goal, the Fund may have elevated portfolio turnover.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities of large-capitalization companies, without providing shareholders at least 60 days’ notice. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis and valuation.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, or the market may react to the catalyst differently than expected. Certain catalysts, such as emergence from, or restructuring as a result of, bankruptcy, carry additional risks, and the securities of such companies may be more likely to lose value than the securities of more stable companies. Securities of issuers undergoing such an event may be more volatile than other securities, may at times be illiquid, and may be difficult to value, and management of such a company may be addressing a situation with which it has little experience.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign

 

markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Mid- and Large-Cap Companies Risk. At times, mid- and large-cap companies may be out of favor with investors. Compared to smaller companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of mid-cap companies are often more volatile and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If a strategy is applied at an inappropriate time or market conditions or trends are judged incorrectly, the use of options may lower the Fund’s return. There can be no guarantee that the use of options will increase the Fund’s return or income. In addition, there may be an imperfect correlation between the movement in prices of options and the securities underlying them and there may at times not be a liquid secondary market for various options. An abrupt change in the price of an underlying security could render an option worthless. The prices of options are volatile and are influenced by, among other things, actual and anticipated changes in the value of the underlying instrument, or in interest or currency exchange rates, including the anticipated volatility of the underlying instrument (known as implied volatility), which in turn are affected by the performance of the issuer of the underlying instrument, by fiscal and monetary policies and by national and international political and economic events. As such, prior to the exercise or expiration of the option, the Fund is exposed to implied volatility risk, meaning the value, as based on implied volatility, of an option may increase due to market and economic conditions or views based on the sector or industry in which issuers of the underlying instrument participate, including company-specific factors.

 

By writing put options, the Fund takes on the risk of declines in the value of the underlying instrument, including the possibility of a loss up to the entire strike price of each option it sells, but without the corresponding opportunity to benefit from potential increases in the value of the underlying instrument. When the Fund writes a put option, it assumes the risk that it must purchase the underlying instrument at a strike price that may be higher than the market price of the instrument. If there is a broad market decline and the Fund is not able to close out its written put options, it may result in substantial losses to the Fund. By writing a call option, the Fund may be obligated to deliver instruments underlying an option at less than the market price. When the Fund writes a covered call option, it gives up the opportunity to profit from a price increase in the underlying instrument above the strike price. If a covered call option that the Fund has written is exercised, the Fund will experience a gain or loss from the sale of the underlying instrument, depending on the price at which the Fund purchased the instrument and the strike price of the option. The Fund will receive a premium from writing options, but the premium received may not be sufficient to offset any losses sustained from exercised options. In the case of a covered call, the premium received may be offset by a decline in the market value of the underlying instrument during the option period. If an option that the Fund has purchased is never exercised or closed out, the Fund will lose the amount of the premium it paid and the use of those funds.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Securities Lending Risk. Securities lending involves a possible delay in recovery of the loaned securities or a possible loss of rights in the collateral should the borrower fail financially. The Fund could also lose money if the value of the collateral decreases.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

Prior to April 2, 2012, the Fund had a policy of investing mainly in common stocks of mid- to large-capitalization companies. Its performance prior to that date might have been different if current policies had been in effect.

 

The performance prior to January 11, 2022 is that of the Fund’s Investor Class, which is not offered through this prospectus. Class E would have substantially similar performance to Investor Class because the classes invest in the same portfolio of securities. Because Investor Class has higher expenses than Class E, its performance would have been lower than that of Class E.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund invests in a concentrated portfolio, consisting mainly of common stocks of companies that are selected using a fundamental, bottom-up research approach. The Fund may hold stocks of companies of any market capitalization and in any sector. Under normal market conditions, the Fund typically will hold a limited number of stocks.

 

Portfolio construction is an important component of the investment process and primarily consists of three distinct investment categories: Special Situations, Opportunistic, and Classic. Special Situations have unique attributes (e.g., restructurings, spin-offs, post-bankruptcy equities) that require specific methodologies and customized investment research. Opportunistic investments are companies that have become inexpensive for a tangible reason that the Portfolio Manager believes is temporary. Classic investments are those companies with long histories of shareholder-friendly policies, high-quality management teams and consistent operating performance.

 

The Portfolio Manager performs both quantitative and qualitative analysis in an effort to identify companies that he believes have the potential to increase in value. This potential may be realized in many ways, some of which include: free cash flow generation, product or process enhancements, margin increases, and improved capital structure management. Investments are selected primarily based on fundamental analysis of issuers and their potential in light of their financial condition, industry position, market opportunities, senior management teams and any special situations as well as any relevant economic, political and regulatory factors.

 

As part of his fundamental investment analysis the Portfolio Manager considers Environmental, Social and Governance (ESG) factors he believes are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Manager believes that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Portfolio Manager employs disciplined valuation criteria and dynamic price limits to determine when to buy or sell a stock. The valuation criteria and price limits will change over time as a result of changes in company-specific, industry and market factors. The Portfolio Manager follows a disciplined selling strategy and may sell a stock when it reaches a dynamic price target, when other opportunities appear more attractive, or when the Portfolio Manager’s research indicates deteriorating fundamentals.

 

Although the Fund invests primarily in domestic stocks, it may also invest in stocks of foreign companies.

 

At times, the Portfolio Manager may emphasize certain sectors that he believes will benefit from market or economic trends.
Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock market, the Portfolio Manager’s evaluation of those developments, and the success of the Portfolio Manager in implementing the Fund’s investment strategies. The market’s behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Manager’s evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Manager will be successful in his attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Currency Risk. Currency risk is the risk that foreign currencies will decline in value relative to the U.S. dollar. To the extent that the Fund invests in securities or other instruments denominated in or indexed to foreign currencies, changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities; or by currency controls or political developments in the U.S. or abroad.

 

Foreign Risk. Foreign securities involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, foreign markets may perform differently than the U.S. markets. The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

 

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. Trading suspensions may be applied from time to time to the securities of individual issuers for reasons specific to that issuer, or may be applied broadly by exchanges or governmental authorities in response to market events. In the event that the Fund holds material positions in such suspended securities or instruments, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

 

Growth Stock Risk. Because the prices of most growth stocks are based on future expectations, these stocks tend to be more sensitive than value stocks to bad economic news and negative earnings surprises. When these expectations are not met or decrease, the prices of these stocks may decline, sometimes sharply, even if earnings showed an absolute increase. Bad economic news or changing investor perceptions may adversely affect growth stocks across several sectors and industries simultaneously.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

The Fund’s portfolio may contain fewer securities than the portfolios of other mutual funds, which increases the risk that the value of the Fund could go down because of the poor performance of one or a few investments.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted.

 

Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in particular sectors, its performance will be especially sensitive to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

 

Special Situations Risk. Companies that are considered “special situations” include, among others: companies that have unrecognized recovery prospects or new management teams; companies involved in restructurings or spin-offs; companies emerging from, or restructuring as a result of, bankruptcy; companies making initial public offerings that trade below their initial offering prices; and companies with a break-up value above their market price. Investing in special situations carries the risk that certain of such situations may not happen as anticipated or the market may react differently than expected to such situations. The securities of companies involved in special situations may be more volatile than other securities, may at times be illiquid, or may be difficult to value.

 

Certain special situations carry the additional risks inherent in difficult corporate transitions and the securities of such companies may be more likely to lose value than the securities of more stable companies.

 

Value Stock Risk. Value stocks may remain undervalued for extended periods of time, may decrease in value during a given period, may not ever realize what the portfolio management team believes to be their full value, or the portfolio management team’s assumptions about intrinsic value or potential for appreciation may be incorrect. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions or investor preferences.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.

Strategy [Heading] rr_StrategyHeading PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

To pursue its goal, the Fund normally invests at least 80% of its net assets in equity securities issued by real estate investment trusts (“REITs”) and common stocks and other securities issued by other real estate companies. The Fund defines a real estate company as one that derives at least 50% of its revenue from, or has at least 50% of its assets in, real estate.

 

The Fund may invest up to 20% of its net assets in debt securities of real estate companies. These debt securities can be either investment grade securities or below investment grade securities (commonly known as “junk bonds”), provided that, at the time of investment, they are rated at least B by S&P Global Ratings or Moody’s Investors Service, Inc. (or comparably rated by at least one independent credit rating agency) or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund does not normally intend to continue holding securities that are in default or have defaulted with respect to the payment of interest or repayment of principal, but may do so depending on market conditions.

 

The Portfolio Managers make investment decisions through a fundamental analysis of each company. The Portfolio Managers review each company’s current financial condition and industry position, as well as economic and market conditions. In doing so, they evaluate the company’s growth potential, earnings estimates and quality of management, as well as other factors. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

 

As part of their fundamental investment analysis the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by both internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may enhance the Fund’s overall investment process. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy.

 

The Fund is a non-diversified fund, which means that it can invest more of its assets in fewer companies than a diversified fund. The Fund concentrates its assets in the real estate industry. The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care.

 

Some of the REITs and other real estate securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

 

The Fund normally seeks to invest for the long-term, but it may sell securities regardless of how long they have been held if the Portfolio Managers find an opportunity they believe is more compelling, or if the Portfolio Managers’ outlook on the company or the market changes, if a stock reaches a target price, if a company’s business fails to perform as expected, or when other opportunities appear more attractive.

 

The Fund will not change its strategy of normally investing at least 80% of its net assets in equity securities issued by REITs and common stocks and other securities issued by other real estate companies, without providing shareholders at least 60 days’ notice. This test and the test of whether a company is a real estate company are applied at the time the Fund invests; later percentage changes caused by a change in Fund assets, market values or company circumstances will not require the Fund to dispose of a holding.

Risk [Heading] rr_RiskHeading PRINCIPAL INVESTMENT RISKS
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

Most of the Fund’s performance depends on what happens in the stock and real estate markets, the Portfolio Managers’ evaluation of those developments, and the success of the Portfolio Managers in implementing the Fund’s investment strategies. The markets’ behavior can be difficult to predict, particularly in the short term. There can be no guarantee that the Fund will achieve its goal. The Fund may take temporary defensive and cash management positions; to the extent it does, it will not be pursuing its principal investment strategies.

 

The actual risk exposure taken by the Fund in its investment program will vary over time, depending on various factors including the Portfolio Managers’ evaluation of issuer, political, regulatory, market, or economic developments. There can be no guarantee that the Portfolio Managers will be successful in their attempts to manage the risk exposure of the Fund or will appropriately evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and ESG factors.

 

The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency. The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.

 

Each of the following risks, which are described in alphabetical order and not in order of any presumed importance, can significantly affect the Fund’s performance. The relative importance of, or potential exposure as a result of, each of these risks will vary based on market and other investment-specific considerations.

 

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. 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 by affecting the credit quality or value of the Fund’s securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

 

Dividend Risk. There is no guarantee that the companies in which the Fund invests will declare dividends in the future or that dividends, if declared, will remain at current levels or increase over time. 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.

 

High Portfolio Turnover. The Fund may engage in active and frequent trading and may have a high portfolio turnover rate, which may increase the Fund’s transaction costs, may adversely affect the Fund’s performance and may generate a greater amount of capital gain distributions to shareholders than if the Fund had a low portfolio turnover rate.

 

Interest Rate Risk. In general, the value of investments with interest rate risk, such as debt securities, will move in the direction opposite to movements in interest rates. If interest rates rise, the value of such securities may decline. Typically, the longer the maturity or duration of a debt security, the greater the effect a change in interest rates could have on the security’s price. Thus, the sensitivity of the Fund’s debt securities to interest rate risk will increase with any increase in the duration of those securities.

 

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole.

 

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price during times when the economy is weak or is expected to become weak. These securities also may require a greater degree of judgment to establish a price and may be difficult to sell at the time and price the Fund desires. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

 

Market Capitalization Risk. To the extent the Fund invests in securities of small-, mid-, or large-cap companies, it takes on the associated risks. At times, any of these market capitalizations may be out of favor with investors. Compared to small- and mid-cap companies, large-cap companies may be unable to respond as quickly to changes and opportunities and may grow at a slower rate. Compared to large-cap companies, small- and mid-cap companies may depend on a more limited management group, may have a shorter history of operations, less publicly available information, less stable earnings, and limited product lines, markets or financial resources. The securities of small- and mid-cap companies are often more volatile, which at times can be rapid and unpredictable, and less liquid than the securities of larger companies and may be more affected than other types of securities by the underperformance of a sector, during market downturns, or by adverse publicity and investor perceptions.

 

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Geopolitical and other risks, including environmental and public health risks may add to instability in world economies and markets generally. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance.

 

Non-Diversified Fund Risk. The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

 

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks.

 

Recent Market Conditions. 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. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

 

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks began to raise interest rates as part of their efforts to address rising inflation. It is difficult to accurately predict the pace at which interest rates might increase, or the timing, frequency or magnitude of any such increases in interest rates.

 

Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected increases in interest rates could lead to market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility or reduce liquidity across various markets.

 

Some countries, including the U.S., have in recent years adopted more protectionist trade policies. Slowing global economic growth, the rise in protectionist trade policies, changes to some major international trade agreements, risks associated with the trade agreement between the United Kingdom and the European Union, and the risks associated with ongoing trade negotiations with China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, the current strength of the U.S. dollar may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.

 

Russia’s invasion of the Ukraine, and corresponding events in late February 2022, have had, and could continue to have, severe adverse effects on regional and global economic markets for securities and commodities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of the Fund’s investments. The duration of ongoing hostilities and the vast array of sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of the Fund and its investments or operations could be negatively impacted.

 

The impact of the COVID-19 pandemic has negatively affected and could 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. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

 

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty.

 

There is widespread 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 impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

 

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund and the risk is heightened during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs, and create adverse tax consequences.

 

REITs and Other Real Estate Companies Risk. REITs and other real estate company securities are subject to risks similar to those of direct investments in real estate and the real estate industry in general, including, among other risks: general and local economic conditions; changes in interest rates; declines in property values; defaults by mortgagors or other borrowers and tenants; increases in property taxes and other operating expenses; overbuilding in their sector of the real estate market; fluctuations in rental income; lack of availability of mortgage funds or financing; extended vacancies of properties, especially during economic downturns; changes in tax and regulatory requirements; losses due to environmental liabilities; casualty or condemnation losses; or other economic, social, political, or regulatory matters affecting the real estate industry. 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 investment income and net realized gains under the Internal Revenue Code of 1986, as amended, (“Code”) or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. The value of REIT common shares may decline when interest rates rise. REITs and other real estate company securities tend to be small- to mid-cap securities and are subject to the risks of investing in small- to mid-cap securities.

 

Sector Risk. Although the Fund will not invest in real estate directly, because it concentrates its assets in the real estate industry your investment in the Fund will be closely linked to the performance of the real estate markets and the value of the Fund’s shares may change at different rates compared to the value of shares of a fund with investments in a mix of different sectors or industries.

 

The Fund may at times emphasize particular sub-sectors of the real estate business — for example, apartments, regional malls, offices, infrastructure, industrial, and health care. As such, the Fund’s performance would be especially sensitive to developments that significantly affect those businesses.

 

Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector or sub-sector may all react in the same way to economic, political or regulatory events.

 

A summary of the Fund’s additional principal investment risks is as follows:

 

Risk of Increase in Expenses. A decline in the Fund’s average net assets during the current fiscal year due to market volatility or other factors could cause the Fund’s expenses for the current fiscal year to be higher than the expense information presented in “Fees and Expenses.”

 

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks or unintentional events. It is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other 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.

 

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 may 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. The Fund could experience losses if judgments about risk prove to be incorrect.

 

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. Such differences could be significant, particularly for illiquid securities and securities that trade in relatively thin markets and/or markets that experience extreme volatility. If market or other conditions make it difficult to value an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment’s most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. 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.
Risk Lose Money [Text] rr_RiskLoseMoney The value of your investment may fall, sometimes sharply, and you could lose money by investing in the Fund.
RIsk Not Insured [Text] rr_RiskNotInsured The Fund is a mutual fund, not a bank deposit, and is not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.
Risk Nondiversified Status [Text] rr_RiskNondiversifiedStatus The Fund is classified as non-diversified. As such, the percentage of the Fund’s assets invested in any single issuer or a few issuers is not limited as much as it is for a Fund classified as diversified. Investing a higher percentage of its assets in any one or a few issuers could increase the Fund’s risk of loss and its share price volatility, because the value of its shares would be more susceptible to adverse events affecting those issuers.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund’s performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in “Descriptions of Indices” in the prospectus, has characteristics relevant to the Fund’s investment strategy.

 

As of June 19, 2012, the Fund changed its investment policy to become “non-diversified” under the Investment Company Act of 1940. Its performance prior to this change might have been different if current policies had been in effect.

 

The performance prior to January 11, 2022 is that of the Fund’s Trust Class, which is not offered through this prospectus. Class E would have substantially similar performance to Trust Class because the classes invest in the same portfolio of securities. Because Trust Class has higher expenses than Class E, its performance typically would have been lower than that of Class E.

 

Returns would have been lower if the Manager had not reimbursed certain expenses and/or waived a portion of the investment management fees during certain of the periods shown.
