These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. 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. More information about these and other discounts is available from your investment provider and in “Sales Charge Reductions and Waivers” on page 209 in the Fund’s prospectus and in “Additional Purchase Information–Sales Charge Reductions and Waivers” on page B-1 in Appendix B in the Fund’s Statement of Additional Information.

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 118% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 118.00%
Expenses Deferred Charges [Text Block] rr_ExpensesDeferredChargesTextBlock 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.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock
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 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 Manager looks for what he believes to be well-managed companies whose stock prices are undervalued. The Portfolio Manager seeks to identify companies with catalysts that he believes 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 Manager 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 seeks to reduce risk by diversifying among many companies and industries. However, at times, the Portfolio Manager may emphasize certain sectors or industries that he believes are undervalued relative to their historical valuations.

The Fund may also use options, including writing (selling) calls against positions in the portfolio (“covered calls”) or writing (selling) puts on individual stocks, to attempt to enhance returns.

The Portfolio Manager follows a disciplined selling strategy and may sell a stock 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 may change its goal without shareholder approval, although it does not currently intend to do so. The Fund will not change its strategy of normally investing at least 80% of its net assets in common stocks 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 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; in such a case, it will not be pursuing its principal investment strategies.

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.

The following risks, which are described in alphabetical order and not in order of importance or potential exposure, can significantly affect the Fund’s performance:

Catalyst Risk. Investing in companies in anticipation of a catalyst carries the risk that the catalyst may not happen as anticipated, possibly due to the actions of other market participants, or the market may react differently than expected to the catalyst. 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. It also may be difficult to obtain complete information about companies involved in certain situations and management of such a company may be addressing a situation with which it has little experience.

Currency Risk. Changes in currency exchange rates could adversely impact investment gains or add to investment losses. Currency exchange rates can be affected unpredictably by intervention, or failure to intervene, by U.S. or foreign governments or central banks 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; 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, 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.

Securities of issuers traded on 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, 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. 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 less responsive to changes and opportunities. Compared to larger companies, mid-cap companies may depend on a more limited management group, may have a shorter history of operations, and may have 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 or during market downturns.

Operational Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational risks arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. It is not possible for the Manager or the other Fund service providers to identify all of the operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Options Risk. The use of options involves investment strategies and risks different from those associated with ordinary portfolio securities transactions. If the Portfolio Manager applies a strategy at an inappropriate time or judges market conditions or trends 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. Government legislation or regulation could affect the use of derivatives and could limit the Fund’s ability to pursue its investment strategies.
 

When the Fund writes a covered call option, it assumes the risk that it will have to sell the underlying security at an exercise price that may be lower than the market price of the security, and it gives up the opportunity to profit from a price increase in the underlying security above the exercise price. When the Fund writes a put option, it assumes the risk that it will have to purchase the underlying security at an exercise price that may be higher than the market price of the security.

Recent Market Conditions. Since the financial crisis that started in 2008, the U.S. and many foreign economies continue to experience its after-effects, which have resulted, and may continue to result, in slower growth and an unusually high degree of volatility in the financial markets, both domestic and foreign. Because the impact on the markets has been widespread, it may be difficult to identify both risks and opportunities using past models of the interplay of market forces, or to predict the duration of these market conditions. In addition, global economies and financial markets are increasingly interconnected, which increases the possibilities that conditions in one country or region might adversely impact issuers in a different country or region. Official statistics indicate a recent growth rate in China that is significantly lower than that in the early part of the decade. This is adversely affecting worldwide commodity prices and the economies of many countries, especially those that depend heavily on commodity production and/or trade with China. The severity or duration of adverse economic conditions may also be affected by policy changes made by governments or quasi-governmental organizations.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. Interest rates have been unusually low in recent years in the U.S. and abroad. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by U.S. policy makers or by dislocations in world markets.

In addition, political 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, perhaps suddenly and to a significant degree. The results of the recent U.S. presidential election appear to herald significant changes in certain policies, which may result in lower corporate taxes, higher levels of public debt, higher interest rates, more restrictions on international trade, and less stringent prudential regulation of certain players in the financial markets.

Redemption Risk. The Fund may experience periods of heavy redemptions that could cause the Fund to sell assets at inopportune times or at a loss or depressed value. Redemption risk is heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Fund’s performance.

Risk Management. Risk is an essential part of investing. No risk management program can eliminate the Fund’s exposure to adverse events; at best, it 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.

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.”

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.

Valuation Risk. The Fund may not be able to sell an investment at the price at which the Fund has valued the investment. 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.

Value Stock Risk. Value stocks may remain undervalued or may decrease in value during a given period or may not ever realize what the portfolio management team believes to be their full value. This may happen, among other reasons, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions.

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 next to 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.

The Fund had a lower management fee and a different goal and strategy, which included investing in stocks of any market capitalization with higher than average dividend yields, prior to June 12, 2009. Its performance prior to that date might have been different if current policies had been in effect.

For each class, the performance prior to April 19, 2010, is that of the Fund’s Trust Class and, for Class A and Class C, the performance from April 19, 2010 to March 2, 2011, is that of the Fund’s Institutional Class. On April 19, 2010, Trust Class shares of the Fund converted into Institutional Class shares of the Fund. Because Trust Class had higher expenses than Institutional Class, its performance typically would have been lower than that of Institutional Class. Because Trust Class and Institutional Class have lower expenses than Class A and Class C, the performance of Trust Class and Institutional Class 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.

[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, taxes, brokerage commissions, acquired fund fees and expenses, dividend and interest expenses relating to short sales, and extraordinary expenses, if any) of each class are limited to 1.11%, 1.86% and 0.75% of average net assets, respectively. Each of these undertakings lasts until 8/31/2020 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 1.11%, 1.86% and 0.75% 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.
