Portfolio Turnover [Text Block] oef_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 16% of the average value of its portfolio.

Strategy [Heading] oef_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] oef_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.
Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading PERFORMANCE
Performance Narrative [Text Block] oef_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 and additional indices. The broad-based market index is required by regulation. The additional index or indices have characteristics relevant to the Fund’s investment strategy. The indices are described in “Descriptions of Indices” in the prospectus. 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.

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 or regulatory developments in the U.S. or abroad.

Risk [Text Block] oef_RiskTextBlock
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.); imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals; 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. market. 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.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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 or other factors, 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, by adverse publicity and investor perceptions, by interest rate changes and by government regulation.

Risk [Text Block] oef_RiskTextBlock
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.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Recent Market Conditions. Both U.S. and international markets have experienced significant volatility in recent 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 or changing, which may impact such economies and markets in ways that cannot be foreseen at this time.
Some countries, including the U.S., have adopted more protectionist trade policies, which is a trend that appears to be continuing globally. Slowing global economic growth, the rise in protectionist trade policies, inflationary pressures, changes to some major international trade and security agreements, risks associated with the trade and security agreement between countries and regions, including the U.S. and other foreign nations, political or economic dysfunction within some countries or regions, including the U.S., and dramatic changes in consumer sentiment, commodity prices and currency values could affect the economies and markets of many nations, including the U.S., in ways that cannot necessarily be foreseen at the present time and may create significant volatility in the markets. In addition, these policies, including the impact on the U.S. dollar, may decrease foreign demand for U.S. assets, which could have a negative impact on certain issuers and/or industries.
The Federal Reserve and certain foreign central banks have started to lower interest rates, though economic or other factors, such as inflation, could stop such changes. It is difficult to accurately predict the pace at which interest rates might change, the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or again reverse course. 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 changes in interest rates could lead to significant 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, reduce liquidity across various markets or decrease confidence in the markets.
Regulators in the U.S. have adopted a number of changes to regulations involving the markets and issuers, some of which apply to the Fund. The full effect of such regulations is not currently known and certain changes to regulation could limit the Fund’s ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, or adversely impact performance. Additionally, it is possible that such regulations could be further revised or rescinded, which creates material uncertainty on their impact to the Fund.
Advancements in technology, including advanced development and increased regulation of artificial intelligence, may adversely impact market movements and liquidity. As artificial intelligence is used more widely, which can occur relatively rapidly, the profitability and growth of certain issuers and industries may be negatively impacted in ways that cannot be foreseen and could adversely impact its performance.
Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East, or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities and any 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.
High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. There is no assurance that the U.S. Congress will act to raise the nation’s debt ceiling; a failure to do so could cause market turmoil and substantial investment risks that cannot now be fully predicted. Unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy.
Global climate change can have potential effects 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, including any direct or indirect consequences that may not be foreseen, may negatively impact certain issuers, industries and regions.

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.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
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; changing social trends regarding working arrangements; or other economic, social, political, or regulatory matters affecting the real estate industry. REITs also are dependent upon the skills and creditworthiness of their managers, subject to heavy cash flow dependency or self-liquidation and generally not diversified.
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 or sub-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 are those stocks whose stock prices, whether based on earnings, book value, or other financial measures, do not reflect their full economic opportunities. 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:

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, processing and communications errors, counterparty and third-party disruptions or 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, including those related to critical functions. 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.
Artificial Intelligence. The Fund and its service providers, including its adviser, may utilize artificial intelligence (“AI”) technologies, including machine learning models and generative AI, to improve operational efficiency and in connection with research. In addition, counterparties used by the Fund may utilize AI in their business activities. While the Manager may restrict certain uses of AI tools, the Fund and its adviser are not in a position to control the use of AI in third-party products or services. The use of AI introduces numerous potential challenges and the use of AI can lead to reputational damage, legal liabilities, and competitive disadvantages, as well as negatively impact business operations, which may occur with or without mismanagement in the use of the AI. AI requires the collection and processing of substantial amounts of data, which poses risks of data inaccuracies, incompleteness, and inherent biases, and which can degrade the technology’s effectiveness and reliability. Such data can include proprietary information, the use of which by AI may be unauthorized and subject to potential liability. Rapid technological advancements further complicate risk predictions, and competitors who adopt AI more swiftly may gain a competitive edge. The complexity and opacity of AI systems raise significant accountability and ethical concerns. AI has enhanced the ability of threat actors to amplify the potency, scale, and speed of cybersecurity attacks. AI’s role in increasing automation raises concerns about job displacement and may lead to economic and social disruptions. The unpredictable nature of AI’s impact on market dynamics complicates traditional risk assessment models, making it challenging to identify risks and opportunities using historical data. Legal and regulatory frameworks governing AI’s use, particularly concerning data privacy and protection, are evolving rapidly. These changes could materially alter how AI is used, which may negatively impact the Fund.

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.

[1] For Class A shares, a contingent deferred sales charge (“CDSC”) of 1.00% applies on certain redemptions made within 18 months following purchases of $1 million or more made without an initial sales charge. For Class C shares, the CDSC is eliminated one year after purchase.
[2] Neuberger Berman Investment Advisers LLC (“Manager”) has contractually undertaken to waive and/or reimburse certain fees and expenses of Class A, Class C and Institutional Class so that the total annual operating expenses (excluding interest, brokerage commissions, acquired fund fees and expenses, taxes including any expenses relating to tax reclaims, dividend and interest expenses relating to short sales, and extraordinary expenses, if any) (“annual operating expenses”) of each class are limited to 1.21%, 1.96% and 0.85% of average net assets, respectively. Each of these undertakings lasts until 8/31/2029 and may not be terminated during its term without the consent of the Board of Trustees. The Fund has agreed that each of Class A, Class C and Institutional Class will repay the Manager for fees and expenses waived or reimbursed for the class provided that repayment does not cause annual operating expenses to exceed 1.21%, 1.96% and 0.85% of the class’ average net assets, respectively. Any such repayment must be made within three years after the year in which the Manager incurred the expense.
