Fund Summary

International Equity Portfolio

Class I

2 International Equity Portfolio (Class I)

The Portfolio Managers systematically and explicitly include material Environmental, Social and Governance (ESG) risks and opportunities in investment analysis and investment decisions for all securities to help identify high quality securities. The Portfolio Managers conduct ongoing proprietary ESG research, including proactive engagement on ESG issues. The Portfolio Managers assess all securities in relation to their exposure to and the management of material ESG risks.

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 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 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.

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 reasonable 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.

4 International Equity Portfolio (Class I)

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. 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. Some countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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.

5 International Equity Portfolio (Class I)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Payments to Financial Intermediaries

Neuberger Berman BD LLC and/or its affiliates may pay insurance companies or their affiliates, qualified plan administrators, broker-dealers or other financial intermediaries, for services to current and prospective variable contract owners and qualified plan participants who choose the Fund as an investment option. These payments may create a conflict of interest by influencing the financial intermediary and its employees to recommend the Fund over another investment or make the Fund available to their current or prospective variable contract owners and qualified plan participants. Ask your financial intermediary or visit its website for more information.

Descriptions of Certain Practices and Security Types

Emerging Market Countries. Emerging market countries are generally considered to be those countries whose economies are less developed than the economies of countries such as the United States or most nations in Western Europe.

Foreign Stocks. There are many promising opportunities for investment outside the United States. Foreign markets can respond to different factors and therefore may follow cycles that are different from each other. For this reason, many investors put a portion of their portfolios in foreign investments as a way of gaining further diversification.

Growth Investing. For growth investors, the aim is to invest in companies that are already successful but could be even more so. Often, these stocks are in emerging or rapidly growing industries. While most growth stocks are known to investors, they may not yet have reached their full potential. The growth investor looks for indications of continued success.

Value Investing. At any given time, there are companies whose stock prices, whether based on earnings, book value, or other financial measures, do not reflect their full economic opportunities. This happens when investors under-appreciate the business potential of these companies, or are distracted by transient or non-fundamental issues. The value investor examines these companies, searching for those that may rise in price when other investors realize their worth.

9

market countries. In addition, due to jurisdictional limitations, matters of comity and various other factors, U.S. authorities may be limited in their ability to bring enforcement actions against non-U.S. companies and non-U.S. persons in certain emerging market countries. Most foreign and emerging market companies are not subject to the uniform accounting, auditing and financial reporting requirements applicable to issuers in the United States, which may impact the availability and quality of information about foreign and emerging market issuers. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Additionally, in times of market stress, regulatory authorities of different emerging market countries may apply varying techniques and degrees of intervention, which can have an effect on prices. 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.

In addition, foreign markets may perform differently than the U.S. market. Over a given period of time, foreign securities may underperform U.S. securities—sometimes for years. Further, 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. The economies and financial markets of certain regions can be highly interdependent and may decline all at the same time. In addition, certain areas are prone to natural disasters such as earthquakes, volcanic eruptions, floods, droughts or tsunamis and are economically sensitive to environmental events.

The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Some national economies continue to show profound instability, which may in turn affect their international trading and financial partners or other members of their currency bloc.

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 reasonable 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. Growth stocks also may lack the dividends often associated with value stocks that can cushion their decline in a falling market. While the price of any type of stock may rise and fall rapidly, growth stocks may underperform during periods when the market favors value stocks.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility or adverse investor perception. 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. Market

participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. 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. As such, the return on investment in securities of large-cap companies may be less than the return on investment in securities of small- and/or mid-cap companies. 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 may fluctuate more widely in price than the market as a whole, which at times can be rapid and unpredictable, may be difficult to sell when the economy is not robust or during market downturns, 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. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities and the Fund may not be able to liquidate a position at a particular time.

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

11

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff

“wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An

13

individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund’s recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

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.

To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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 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 because value stocks, as a category, lose favor with investors compared to growth stocks, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions, or because the stocks’ worth was misgauged. Entire industries or sectors may lose favor with investors, and the Fund, in seeking value stocks, may focus its investments more heavily in those industries or sectors.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending or should the Fund use derivatives, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

14

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

19

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class I shares of the Fund.

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund. You should refer to the prospectus for your variable contract or your qualified plan documentation, or consult with your tax adviser, for information regarding taxes applicable to your variable contract or qualified plan, as applicable.

Fund Summary

International Equity Portfolio

Class S

2 International Equity Portfolio (Class S)

The Portfolio Managers systematically and explicitly include material Environmental, Social and Governance (ESG) risks and opportunities in investment analysis and investment decisions for all securities to help identify high quality securities. The Portfolio Managers conduct ongoing proprietary ESG research, including proactive engagement on ESG issues. The Portfolio Managers assess all securities in relation to their exposure to and the management of material ESG risks.

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 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 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.

3 International Equity Portfolio (Class S)

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 reasonable 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.

4 International Equity Portfolio (Class S)

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. 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. Some countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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.

5 International Equity Portfolio (Class S)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Emerging Market Countries. Emerging market countries are generally considered to be those countries whose economies are less developed than the economies of countries such as the United States or most nations in Western Europe.

Foreign Stocks. There are many promising opportunities for investment outside the United States. Foreign markets can respond to different factors and therefore may follow cycles that are different from each other. For this reason, many investors put a portion of their portfolios in foreign investments as a way of gaining further diversification.

Growth Investing. For growth investors, the aim is to invest in companies that are already successful but could be even more so. Often, these stocks are in emerging or rapidly growing industries. While most growth stocks are known to investors, they may not yet have reached their full potential. The growth investor looks for indications of continued success.

Value Investing. At any given time, there are companies whose stock prices, whether based on earnings, book value, or other financial measures, do not reflect their full economic opportunities. This happens when investors under-appreciate the business potential of these companies, or are distracted by transient or non-fundamental issues. The value investor examines these companies, searching for those that may rise in price when other investors realize their worth.

9

market countries. In addition, due to jurisdictional limitations, matters of comity and various other factors, U.S. authorities may be limited in their ability to bring enforcement actions against non-U.S. companies and non-U.S. persons in certain emerging market countries. Most foreign and emerging market companies are not subject to the uniform accounting, auditing and financial reporting requirements applicable to issuers in the United States, which may impact the availability and quality of information about foreign and emerging market issuers. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Additionally, in times of market stress, regulatory authorities of different emerging market countries may apply varying techniques and degrees of intervention, which can have an effect on prices. 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.

In addition, foreign markets may perform differently than the U.S. market. Over a given period of time, foreign securities may underperform U.S. securities—sometimes for years. Further, 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. The economies and financial markets of certain regions can be highly interdependent and may decline all at the same time. In addition, certain areas are prone to natural disasters such as earthquakes, volcanic eruptions, floods, droughts or tsunamis and are economically sensitive to environmental events.

The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Some national economies continue to show profound instability, which may in turn affect their international trading and financial partners or other members of their currency bloc.

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 reasonable 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. Growth stocks also may lack the dividends often associated with value stocks that can cushion their decline in a falling market. While the price of any type of stock may rise and fall rapidly, growth stocks may underperform during periods when the market favors value stocks.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility or adverse investor perception. 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. Market

participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. 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. As such, the return on investment in securities of large-cap companies may be less than the return on investment in securities of small- and/or mid-cap companies. 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 may fluctuate more widely in price than the market as a whole, which at times can be rapid and unpredictable, may be difficult to sell when the economy is not robust or during market downturns, 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. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities and the Fund may not be able to liquidate a position at a particular time.

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff

12

“wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An

13

individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund's recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

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.

To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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 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 because value stocks, as a category, lose favor with investors compared to growth stocks, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions, or because the stocks’ worth was misgauged. Entire industries or sectors may lose favor with investors, and the Fund, in seeking value stocks, may focus its investments more heavily in those industries or sectors.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending or should the Fund use derivatives, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

14

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

19

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class S shares of the Fund.

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund. You should refer to the prospectus for your variable contract or your qualified plan documentation, or consult with your tax adviser, for information regarding taxes applicable to your variable contract or qualified plan, as applicable.

21

Generally, no earlier than five business days after month-end, the Fund may publicly disclose via various shareholder and public communications, such as portfolio manager commentaries, fact sheets or other marketing materials, which will be publicly available at www.nb.com, certain portfolio characteristics and partial information concerning portfolio holdings for the month as of month-end, including but not limited to: up to the top 10 holdings of the Fund (if the Fund engages in short selling, it may also disclose up to the top 10 short positions); up to the top 10 holdings that contributed to and/or detracted from performance or were the best and/or worst performers; sector breakdowns or changes to portfolio composition (e.g., buys and sells). This information will typically remain available at this website until information for the subsequent month has been posted; however, to comply with Rule 30e-3 under the Investment Company Act of 1940, as amended, quarter-end information may be retained on this website for the Fund’s previous fiscal year. The Fund may also post intra-month updates to holdings and certain portfolio characteristics to www.nb.com. Any such intra-month update would be in addition to and not in lieu of the holdings disclosure policies described above.

ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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

4 Mid Cap Growth Portfolio (Class I)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Growth Investing. For growth investors, the aim is to invest in companies that are already successful but could be even more so. Often, these stocks are in emerging or rapidly growing industries. While most growth stocks are known to investors, they may not yet have reached their full potential. The growth investor looks for indications of continued success.

or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory

8

responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

9

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund’s recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

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.

To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending or should the Fund use derivatives or invest in foreign securities, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

Foreign securities, including those issued by foreign governments, involve risks in addition to those associated with comparable U.S. securities, and can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

Neither this Prospectus nor the Statement of Additional Information is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that have not been waived. The Fund enters into contractual arrangements with various parties, including, among others, the Manager, who provide services to the Fund. Shareholders are not parties to, or intended to be third party beneficiaries of, those contractual arrangements. Where shareholders are not third party beneficiaries of contractual arrangements, those contractual arrangements cannot be enforced by shareholders acting on their own behalf.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

15

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class I shares of the Fund.

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

Fund Summary

Mid Cap Growth Portfolio

Class S

2 Mid Cap Growth Portfolio (Class S)

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 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 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.

of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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:

4 Mid Cap Growth Portfolio (Class S)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Payments to Financial Intermediaries

Neuberger Berman BD LLC and/or its affiliates may pay insurance companies or their affiliates, qualified plan administrators, broker-dealers or other financial intermediaries, for services to current and prospective variable contract owners and qualified plan participants who choose the Fund as an investment option. These payments may create a conflict of interest by influencing the financial intermediary and its employees to recommend the Fund over another investment or make the Fund available to their current or prospective variable contract owners and qualified plan participants. Ask your financial intermediary or visit its website for more information.

Descriptions of Certain Practices and Security Types

Growth Investing. For growth investors, the aim is to invest in companies that are already successful but could be even more so. Often, these stocks are in emerging or rapidly growing industries. While most growth stocks are known to investors, they may not yet have reached their full potential. The growth investor looks for indications of continued success.

or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory

9

responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

10

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund’s recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

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.

To the extent that the portfolio securities acquired with such collateral have decreased in value, it may result in the Fund realizing a loss at a time when it would not otherwise do so. As such, securities lending may introduce leverage into the Fund. The Fund also may incur losses if the returns on securities that it acquires with cash collateral are less than the applicable rebate rates paid to borrowers and related administrative costs.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending or should the Fund use derivatives or invest in foreign securities, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

Foreign securities, including those issued by foreign governments, involve risks in addition to those associated with comparable U.S. securities, and can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

A discussion regarding the basis for the Board of Trustees’ approval of the investment advisory agreement is available in the Fund's annual report for the fiscal period ended December 31, 2021.

NBIA may engage one or more of foreign affiliates that are not registered under the 1940 Act (“participating affiliates”) in accordance with applicable SEC no-action letters. As participating affiliates, whether or not registered with the SEC, the affiliates may provide designated investment personnel to associate with NBIA as “associated persons” of NBIA and perform specific advisory services for NBIA, including services for the Fund, which may involve, among other services, portfolio management and/or placing orders for securities and other instruments. The designated employees of a participating affiliate act for NBIA and are subject to certain NBIA policies and procedures as well as supervision and periodic monitoring by NBIA. The Fund will pay no additional fees and expenses as a result of any such arrangements.

Neither this Prospectus nor the Statement of Additional Information is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that have not been waived. The Fund enters into contractual arrangements with various parties, including, among others, the Manager, who provide services to the Fund. Shareholders are not parties to, or intended to be third party beneficiaries of, those contractual arrangements. Where shareholders are not third party beneficiaries of contractual arrangements, those contractual arrangements cannot be enforced by shareholders acting on their own behalf.

Portfolio Managers

Please see the Statement of Additional Information for additional information about each Portfolio Manager’s compensation, other accounts managed by each Portfolio Manager, and each Portfolio Manager’s ownership of Fund shares.

Kenneth J. Turek is a Managing Director of the Manager. Mr. Turek has been the Portfolio Manager of the Fund since 2003.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

16

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class S shares of the Fund.

17

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund. You should refer to the prospectus for your variable contract or your qualified plan documentation, or consult with your tax adviser, for information regarding taxes applicable to your variable contract or qualified plan, as applicable.

18

Generally, no earlier than five business days after month-end, the Fund may publicly disclose via various shareholder and public communications, such as portfolio manager commentaries, fact sheets or other marketing materials, which will be publicly available at www.nb.com, certain portfolio characteristics and partial information concerning portfolio holdings for the month as of month-end, including but not limited to: up to the top 10 holdings of the Fund (if the Fund engages in short selling, it may also disclose up to the top 10 short positions); up to the top 10 holdings that contributed to and/or detracted from performance or were the best and/or worst performers; sector breakdowns or changes to portfolio composition (e.g., buys and sells). This information will typically remain available at this website until information for the subsequent month has been posted; however, to comply with Rule 30e-3 under the Investment Company Act of 1940, as amended, quarter-end information may be retained on this website for the Fund’s previous fiscal year. The Fund may also post intra-month updates to holdings and certain portfolio characteristics to www.nb.com. Any such intra-month update would be in addition to and not in lieu of the holdings disclosure policies described above.

Fund Summary

Mid Cap Intrinsic Value Portfolio

Class I

2 Mid Cap Intrinsic Value Portfolio (Class I)

■	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.

3 Mid Cap Intrinsic Value Portfolio (Class I)

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.); 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. 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, 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

4 Mid Cap Intrinsic Value Portfolio (Class I)

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. 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. Some countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since

5 Mid Cap Intrinsic Value Portfolio (Class I)

property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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.

6 Mid Cap Intrinsic Value Portfolio (Class I)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Foreign Stocks. There are many promising opportunities for investment outside the United States. Foreign markets can respond to different factors and therefore may follow cycles that are different from each other. For this reason, many investors put a portion of their portfolios in foreign investments as a way of gaining further diversification.

REITs. A REIT is a pooled investment vehicle that invests primarily in income-producing real estate or real estate related loans or interests. A domestic REIT is not taxed on net income and net realized gains that are distributed to its shareholders, provided it complies with certain requirements of the Internal Revenue Code of 1986, as amended (“Code”), and similar treatment may also apply to foreign REITs under the laws in which they are formed. REITs are generally classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property, derive their income primarily from rents and can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs.

Value Investing. At any given time, there are companies whose stock prices, whether based on earnings, book value, or other financial measures, do not reflect their full economic opportunities. This happens when investors under-appreciate the business potential of these companies, or are distracted by transient or non-fundamental issues. The value investor examines these companies, searching for those that may rise in price when other investors realize their worth.

9

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, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

In addition, foreign markets may perform differently than the U.S. market. Over a given period of time, foreign securities may underperform U.S. securities—sometimes for years. The Fund could also underperform if it invests in countries or regions whose economic performance falls short. To the extent that the Fund invests a portion of its assets in one country, state, region or currency, an adverse economic, business or political development may affect the value of the Fund’s investments more than if its investments were not so invested.

The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Some national economies continue to show profound instability, which may in turn affect their international trading and financial partners or other members of their currency bloc.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility or adverse investor perception. 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. Market participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. 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. As such, the return on investment in securities of large-cap companies may be less than the return on investment in securities of small- and/or mid-cap companies. 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 may fluctuate more widely in price than the market as a whole, which at times can be rapid and unpredictable, may be difficult to sell when the economy is not robust or during market downturns, 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. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities and the Fund may not be able to liquidate a position at a particular time.

The Fund defines mid-capitalization companies by reference to the market capitalization range of companies in the named index. The size of companies in an index changes with market conditions. In addition, changes to the composition of an index can change the market capitalization range of companies in the index and, therefore, the market capitalization range of companies in which the Fund invests.

10

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

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. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and 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. A security that was liquid at the time of purchase may subsequently become illiquid. In addition, transaction costs may be higher for private placements and other restricted securities. The Fund may have to bear the expense of registering such securities for sale and there may be substantial delays in effecting the registration. If, during such a delay, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed at the time it decided to seek registration of the securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security, so it may be less able to anticipate a loss. Also, if Fund management receives material non-public information about the issuer, the Fund may, as a result, be legally prohibited from selling the securities.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of

11

many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching

12

the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur 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 Code or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. Effective for taxable years beginning after December 31, 2017 and before January 1, 2026, the Code generally allows individuals and certain other non-corporate entities a deduction for 20% of qualified REIT dividends. Regulations provide that a regulated investment company can pass the character of its qualified REIT dividends through to its shareholders for purposes of benefiting from this deduction. An insurance company separate account or a qualified plan investing in the Fund, however, will not be eligible to benefit from this deduction. While certain of these risk factors may affect only one or a few real estate sectors at a time, others may affect the real estate industry broadly. For example, the value of REIT common shares may decline when interest rates rise. During periods of high interest rates, REITs and other real estate companies may lose appeal for investors who may be able to

13

obtain higher yields from other income-producing investments. High interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain.

Most equity REITs receive a flow of income from property rentals, which, after covering their expenses, they pay to their shareholders in the form of dividends. Equity REITs may be affected by changes in the value of the underlying property they own, while mortgage REITs may be affected by the quality of any credit they extend or mortgages they purchase.

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. Some of the REIT securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund’s recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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 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 because value stocks, as a category, lose favor with investors compared to growth stocks, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions, or because the stocks’ worth was misgauged. Entire industries or sectors may lose favor with investors, and the Fund, in seeking value stocks, may focus its investments more heavily in those industries or sectors.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should

14

the Fund engage in borrowing or securities lending or should the Fund use derivatives, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

19

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class I shares of the Fund.

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund. You should refer to the prospectus for your variable contract or your qualified plan documentation, or consult with your tax adviser, for information regarding taxes applicable to your variable contract or qualified plan, as applicable.

Fund Summary

Mid Cap Intrinsic Value Portfolio

Class S

2 Mid Cap Intrinsic Value Portfolio (Class S)

■	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.

3 Mid Cap Intrinsic Value Portfolio (Class S)

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.); 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. 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, 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

4 Mid Cap Intrinsic Value Portfolio (Class S)

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. 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. Some countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since

5 Mid Cap Intrinsic Value Portfolio (Class S)

property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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.

6 Mid Cap Intrinsic Value Portfolio (Class S)

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Foreign Stocks. There are many promising opportunities for investment outside the United States. Foreign markets can respond to different factors and therefore may follow cycles that are different from each other. For this reason, many investors put a portion of their portfolios in foreign investments as a way of gaining further diversification.

REITs. A REIT is a pooled investment vehicle that invests primarily in income-producing real estate or real estate related loans or interests. A domestic REIT is not taxed on net income and net realized gains that are distributed to its shareholders, provided it complies with certain requirements of the Internal Revenue Code of 1986, as amended (“Code”), and similar treatment may also apply to foreign REITs under the laws in which they are formed. REITs are generally classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property, derive their income primarily from rents and can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs.

Value Investing. At any given time, there are companies whose stock prices, whether based on earnings, book value, or other financial measures, do not reflect their full economic opportunities. This happens when investors under-appreciate the business potential of these companies, or are distracted by transient or non-fundamental issues. The value investor examines these companies, searching for those that may rise in price when other investors realize their worth.

9

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, the Fund’s ability to liquidate its positions or provide liquidity to investors may be compromised and the Fund could incur significant losses.

In addition, foreign markets may perform differently than the U.S. market. Over a given period of time, foreign securities may underperform U.S. securities—sometimes for years. The Fund could also underperform if it invests in countries or regions whose economic performance falls short. To the extent that the Fund invests a portion of its assets in one country, state, region or currency, an adverse economic, business or political development may affect the value of the Fund’s investments more than if its investments were not so invested.

The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Some national economies continue to show profound instability, which may in turn affect their international trading and financial partners or other members of their currency bloc.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility or adverse investor perception. 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. Market participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. 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. As such, the return on investment in securities of large-cap companies may be less than the return on investment in securities of small- and/or mid-cap companies. 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 may fluctuate more widely in price than the market as a whole, which at times can be rapid and unpredictable, may be difficult to sell when the economy is not robust or during market downturns, 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. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities and the Fund may not be able to liquidate a position at a particular time.

The Fund defines mid-capitalization companies by reference to the market capitalization range of companies in the named index. The size of companies in an index changes with market conditions. In addition, changes to the composition of an index can change the market capitalization range of companies in the index and, therefore, the market capitalization range of companies in which the Fund invests.

10

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

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. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and 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. A security that was liquid at the time of purchase may subsequently become illiquid. In addition, transaction costs may be higher for private placements and other restricted securities. The Fund may have to bear the expense of registering such securities for sale and there may be substantial delays in effecting the registration. If, during such a delay, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed at the time it decided to seek registration of the securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security, so it may be less able to anticipate a loss. Also, if Fund management receives material non-public information about the issuer, the Fund may, as a result, be legally prohibited from selling the securities.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of

11

many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching

12

the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur 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 Code or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. Effective for taxable years beginning after December 31, 2017 and before January 1, 2026, the Code generally allows individuals and certain other non-corporate entities a deduction for 20% of qualified REIT dividends. Regulations provide that a regulated investment company can pass the character of its qualified REIT dividends through to its shareholders for purposes of benefiting from this deduction. An insurance company separate account or a qualified plan investing in the Fund, however, will not be eligible to benefit from this deduction. While certain of these risk factors may affect only one or a few real estate sectors at a time, others may affect the real estate industry broadly. For example, the value of REIT common shares may decline when interest rates rise. During periods of high interest rates, REITs and other real estate companies may lose appeal for investors who may be able to

13

obtain higher yields from other income-producing investments. High interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain.

Most equity REITs receive a flow of income from property rentals, which, after covering their expenses, they pay to their shareholders in the form of dividends. Equity REITs may be affected by changes in the value of the underlying property they own, while mortgage REITs may be affected by the quality of any credit they extend or mortgages they purchase.

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. Some of the REIT securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For a summary of the Fund’s recent sector allocations, see its most recent shareholder report. (The information in the report is as of the date of the report and may have changed.) For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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 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 because value stocks, as a category, lose favor with investors compared to growth stocks, because of a failure to anticipate which stocks or industries would benefit from changing market or economic conditions, or because the stocks’ worth was misgauged. Entire industries or sectors may lose favor with investors, and the Fund, in seeking value stocks, may focus its investments more heavily in those industries or sectors.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should

14

the Fund engage in borrowing or securities lending or should the Fund use derivatives, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

Neither this Prospectus nor the Statement of Additional Information is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that have not been waived. The Fund enters into contractual arrangements with various parties, including, among others, the Manager, who provide services to the Fund. Shareholders are not parties to, or intended to be third party beneficiaries of, those contractual arrangements. Where shareholders are not third party beneficiaries of contractual arrangements, those contractual arrangements cannot be enforced by shareholders acting on their own behalf.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

19

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

The Fund uses a “multiple class” structure. The Fund offers Class I and Class S shares that have identical investment programs but different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in the Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates only to Class S shares of the Fund.

will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund. You should refer to the prospectus for your variable contract or your qualified plan documentation, or consult with your tax adviser, for information regarding taxes applicable to your variable contract or qualified plan, as applicable.

21

Generally, no earlier than five business days after month-end, the Fund may publicly disclose via various shareholder and public communications, such as portfolio manager commentaries, fact sheets or other marketing materials, which will be publicly available at www.nb.com, certain portfolio characteristics and partial information concerning portfolio holdings for the month as of month-end, including but not limited to: up to the top 10 holdings of the Fund (if the Fund engages in short selling, it may also disclose up to the top 10 short positions); up to the top 10 holdings that contributed to and/or detracted from performance or were the best and/or worst performers; sector breakdowns or changes to portfolio composition (e.g., buys and sells). This information will typically remain available at this website until information for the subsequent month has been posted; however, to comply with Rule 30e-3 under the Investment Company Act of 1940, as amended, quarter-end information may be retained on this website for the Fund’s previous fiscal year. The Fund may also post intra-month updates to holdings and certain portfolio characteristics to www.nb.com. Any such intra-month update would be in addition to and not in lieu of the holdings disclosure policies described above.

Fund Summary

Real Estate Portfolio

Class S

2 Real Estate Portfolio (Class S)

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.

The Portfolio Managers systematically and explicitly include material Environmental, Social and Governance (ESG) risks and opportunities in investment analysis and investment decisions for all securities to help identify high quality securities. The Portfolio Managers conduct ongoing proprietary ESG research, including proactive engagement on ESG issues. The Portfolio Managers assess all securities in relation to their exposure to and the management of material ESG risks.

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.

3 Real Estate Portfolio (Class S)

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 and may adversely affect the Fund’s performance.

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.

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.

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. 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. Some

4 Real Estate Portfolio (Class S)

countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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

5 Real Estate Portfolio (Class S)

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:

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Lower-Rated Debt Securities. Lower-rated debt securities (commonly known as “junk bonds”) typically offer investors higher yields than other fixed income securities. The higher yields are usually justified by the weaker credit profiles of these issuers as compared to investment grade issuers. Lower-rated debt securities may include debt obligations of all types issued by U.S. and non-U.S. corporate and governmental entities, including bonds, debentures and notes, loan interests and preferred stocks that have priority over any other class of stock of the entity as to the distribution of assets or the payment of dividends. A lower-rated debt security itself may be convertible into or exchangeable for equity securities, or it may carry with it the right to acquire equity securities evidenced by warrants attached to the security or acquired as part of a unit with the security.

REITs. A REIT is a pooled investment vehicle that invests primarily in income-producing real estate or real estate related loans or interests. A domestic REIT is not taxed on net income and net realized gains that are distributed to its shareholders, provided it complies with certain requirements of the Internal Revenue Code of 1986, as amended (“Code”), and similar treatment may also apply to foreign REITs under the laws in which they are formed. REITs are generally classified as equity REITs, mortgage REITs or hybrid REITs. Equity REITs invest the majority of their assets directly in real property, derive their income primarily from rents and can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both equity REITs and mortgage REITs.

security with a duration of two years will decrease in value by approximately 2%. Thus, the sensitivity of the Fund's debt securities to interest rate risk will increase with any increase in the duration of those securities. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Short-term and long-term interest rates, and interest rates in different countries, do not necessarily move in the same direction or by the same amount. The link between interest rates and debt security prices tends to be weaker with lower-rated debt securities than with investment grade debt securities.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

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 may be less liquid and also may require a greater degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, and may carry higher transaction costs. In particular, these securities may be issued by smaller companies or by highly indebted companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal. 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. Such securities are susceptible to such a default or decline in market value due to real or perceived adverse economic and business developments relating to the issuer, the industry in general, market interest rates and market liquidity. 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. Where it deems it appropriate and in the best interests of Fund shareholders, the Fund may incur additional expenses to seek recovery on a defaulted security and/or to pursue litigation to protect the Fund’s investment.

The credit rating of a security may not accurately reflect the actual credit risk associated with such a security. 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.

Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of such securities, especially in a thinly traded or illiquid market. To the extent the Fund owns or may acquire illiquid or restricted lower-rated debt securities or unrated debt securities of comparable quality, these securities may involve special registration responsibilities, liabilities, costs, and liquidity and valuation difficulties.

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. As such, the return on investment in securities of large-cap companies may be less than the return on investment in securities of small- and/or mid-cap companies. 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 may fluctuate more widely in price than the market as a whole, which at times can be rapid and unpredictable, may be difficult to sell when the economy is not robust or during market downturns, 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. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities and the Fund may not be able to liquidate a position at a particular time.

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters

9

or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

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.

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

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, and there is a risk an issuer of preferred securities may call or redeem prior to any stated maturity. Preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer. Preferred shareholders may have certain rights if distributions are not paid, but generally have no legal recourse against the issuer, may suffer a loss of value if distributions are not paid and may be required to report the deferred distribution on its tax returns, even though it may not have received any cash. Generally, preferred shareholders have no voting rights with respect to the issuer unless distributions to preferred shareholders have not been paid for a stated period, at which time the preferred shareholders may elect a number of directors to the issuer’s board. Generally, once all the distributions have been paid to preferred shareholders, the preferred shareholders no longer have voting rights.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of

10

office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian economy and may result in the further decline of the value and liquidity of Russian securities, a continued weakening of the ruble and continued exchange closures, and may have other adverse consequences on the Russian economy that could impact the value of Russian investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

11

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

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, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur 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 Code or to maintain their exemption from registration under the Investment Company Act of 1940, as amended. Effective for taxable years beginning after December 31, 2017 and before January 1, 2026, the Code generally allows individuals and certain other non-corporate entities a deduction for 20% of qualified REIT dividends. Regulations provide that a regulated investment company can pass the character of its qualified REIT dividends through to its shareholders for purposes of benefiting from this deduction. An insurance company separate account or a qualified plan investing in the Fund, however, will not be eligible to benefit from this deduction. While certain of these risk factors may affect only one or a few real estate sectors at a time, others may affect the real estate industry broadly. For example, the value of REIT common shares may decline when interest rates rise. During periods of high interest rates, REITs and other real estate companies may lose appeal for investors who may be able to obtain higher yields from other income-producing investments. High interest rates may also mean that financing for property purchases and improvements is more costly and difficult to obtain.

Most equity REITs receive a flow of income from property rentals, which, after covering their expenses, they pay to their shareholders in the form of dividends. Equity REITs may be affected by changes in the value of the underlying property they own, while mortgage REITs may be affected by the quality of any credit they extend or mortgages they purchase.

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. Some of the REIT securities in which the Fund invests may be preferred stock, which receives preference in the payment of dividends.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 may all react in the same way to economic, political or regulatory events.

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending or should the Fund use derivatives or invest in foreign securities, it will be subject to the additional risks associated with these practices and securities.

Borrowing money, securities lending, or using derivatives would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements. The Fund may, to a limited extent, use certain derivatives for hedging or investment purposes. A derivative instrument, whether used for hedging or for speculation, could fail to perform as expected, causing a loss for the Fund.

Foreign securities, including those issued by foreign governments, involve risks in addition to those associated with comparable U.S. securities, and can fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Securities issued by U.S. entities with substantial foreign operations may involve risks relating to political, economic, or regulatory conditions in foreign countries.

13

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal.

In addition, to the extent the Fund is new or is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

Management of the Fund

Investment Manager

Neuberger Berman Investment Advisers LLC (“Manager”), located at 1290 Avenue of the Americas, New York, NY 10104, is the Fund’s investment manager and administrator. Neuberger Berman BD LLC (“Distributor”), located at 1290 Avenue of the Americas, New York, NY 10104, is the Fund’s distributor. Pursuant to an investment advisory agreement, the Manager is responsible for choosing the Fund’s investments and handling its day-to-day business. The services provided by the Manager as the investment manager and administrator include, among others, overall responsibility for providing all supervisory, management, and administrative services reasonably necessary for the operation of the Fund, which may include, among others, compliance monitoring, operational and investment risk management, legal and administrative services and portfolio accounting services. The Manager carries out its duties subject to the policies established by the Board of Trustees. The investment advisory agreement establishes the fees the Fund pays to the Manager for its services as the Fund’s investment manager and the expenses paid directly by the Fund. Together, the Neuberger Berman affiliates manage approximately $460 billion in total assets (as of 12/31/2021) and continue an asset management history that began in 1939. The Fund pays the Manager a fee at the annual rate of 0.85% of the Fund’s average net assets for investment advisory services. Class S pays the Manager fees at the annual rate of 0.30% of the Class’ average daily net assets for administrative services provided to the class.

A discussion regarding the basis for the Board of Trustees’ approval of the investment advisory agreement will be in the Fund’s shareholder report, when available.

NBIA may engage one or more of foreign affiliates that are not registered under the 1940 Act (“participating affiliates”) in accordance with applicable SEC no-action letters. As participating affiliates, whether or not registered with the SEC, the affiliates may provide designated investment personnel to associate with NBIA as “associated persons” of NBIA and perform specific advisory services for NBIA, including services for the Fund, which may involve, among other services, portfolio management and/or placing orders for securities and other instruments. The designated employees of a participating affiliate act for NBIA and are subject to certain NBIA policies and procedures as well as supervision and periodic monitoring by NBIA. The Fund will pay no additional fees and expenses as a result of any such arrangements.

Neither this Prospectus nor the Statement of Additional Information is intended to give rise to any contract rights or other rights in any shareholder, other than any rights conferred explicitly by federal or state securities laws that have not been waived. The Fund enters into contractual arrangements with various parties, including, among others, the Manager, who provide services to the Fund. Shareholders are not parties to, or intended to be third party beneficiaries of, those contractual arrangements. Where shareholders are not third party beneficiaries of contractual arrangements, those contractual arrangements cannot be enforced by shareholders acting on their own behalf.

it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

18

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

Fund Summary

Short Duration Bond Portfolio

Class I

2 Short Duration Bond Portfolio (Class I)

To enhance yield and add diversification, the Fund may invest up to 20% of its net assets in securities that are below investment grade (commonly known as “junk bonds”). In choosing lower-rated securities, the Portfolio Managers generally look for bonds from issuers whose financial health appears comparatively strong, and that may have their credit ratings raised. The Fund does not normally invest in or 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 or other conditions.

The Fund may invest in foreign securities, including obligations of issuers in emerging market countries, denominated in any currency, but the Fund normally will not invest more than 20% of its total assets at the time of investment in non-US dollar denominated securities. The Fund considers emerging market countries to be countries included in the JPMorgan Emerging Markets Bond Index - Global Diversified, the JPMorgan Corporate Emerging Markets Bond Index - Diversified, the JPMorgan Emerging Local Markets Index or the JPMorgan Government Bond Index - Emerging Markets Global Diversified, as well as those countries which are not defined as High Income Organization for Economic Cooperation and Development (OECD) member countries by the World Bank.

The Fund may also invest in derivative instruments as a means of hedging risk and/or for investment purposes, which may include altering the Fund’s exposure to interest rates, currencies, sectors and individual issuers. These derivative instruments may include futures, forward foreign currency contracts, and swaps.

The Fund may also invest a significant amount of its assets in U.S. Treasury securities or other money market instruments depending on market conditions. Additionally, the Fund may invest in restricted securities. The Fund may also engage in when-issued and forward-settling securities (such as to-be-announced (“TBA”) mortgage-backed securities), which involve a commitment by the Fund to purchase securities that will be issued or settled at a later date.

The Fund seeks to reduce credit risk by diversifying among many issuers and different types of securities. As part of the investment process, the Portfolio Managers analyze individual issues (including an analysis of cash flows, ability to pay principal and interest, balance sheet composition, and market positioning). The Fund’s Portfolio Managers systematically evaluate material Environmental, Social and Governance (ESG) considerations as a factor in their investment analysis. The Portfolio Managers believe that ESG factors, like other more traditional subjects of investment analysis, have the potential to affect financial risk (e.g., an issuer’s overall credit profile) and investment returns. The Portfolio Managers conduct ongoing proprietary ESG research and proactively engage on ESG issues, supplemented by third-party ESG information, and use this as an input to the team’s internal credit ratings, which may be notched up or down depending on the ESG profile of an issuer. ESG considerations that the Portfolio Managers may consider include, but are not limited to: greenhouse gas emissions, data privacy and security, labor management, workforce diversity and inclusion, and business ethics, executive compensation and board composition. The consideration of ESG factors as part of the portfolio managers’ investment process does not mean that the Fund pursues a specific “impact” or “sustainable” investment strategy. Although it may invest in securities of any maturity, the Fund normally seeks to maintain an average portfolio duration of three years or less.

The Fund may invest in other investment companies, including exchange-traded funds (“ETFs”), if the investment companies invest principally in the types of investments in which the Fund may invest directly.

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

The Fund normally invests at least 80% of its net assets in bonds and other debt securities and other investment companies that provide investment exposure to such debt securities. The Fund will not alter this policy 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.

3 Short Duration Bond Portfolio (Class I)

evaluate or weigh the multiple factors involved in investment decisions, including issuer, market and/or instrument-specific analysis, valuation and environmental, social and governance 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. While this Fund may have a shorter duration than many other income funds, this Fund is not intended to operate like a money market 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.

Call Risk. Upon the issuer’s desire to call a security, or under other circumstances where a security is called, including when interest rates are low and issuers opt to repay the obligation underlying a “callable security” early, the Fund may have to reinvest the proceeds in an investment offering a lower yield and may not benefit from any increase in value that might otherwise result from declining interest rates.

Collateralized Debt Obligations Risk. CDOs, which include collateralized loan obligations (CLOs), issue classes or “tranches” of securities that vary in risk and yield and may experience substantial losses due to interest rate fluctuations, actual defaults, collateral defaults, disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CDO securities as a class. The risks of investing in CDOs depend largely on the quality and type of the underlying debt, which may include loans, bonds and mortgages, and the tranche of the CDO in which the Fund invests. In addition, CDOs that obtain their exposure through derivative instruments entail the additional risks associated with such instruments. CDOs can be difficult to value, may at times be illiquid, may be highly leveraged (which could make them highly volatile), and may produce unexpected investment results due to their complex structure. In addition, CDOs involve many of the same risks of investing in debt securities and asset-backed securities including, but not limited to, interest rate risk, credit risk, liquidity risk, and valuation risk.

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. 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.

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 and/or segregate cash or other liquid assets; 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 and/or segregate assets could limit the Fund's ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual and

4 Short Duration Bond Portfolio (Class I)

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:

Forward Contracts. There are no limitations on daily price movements of forward contracts. Changes in foreign exchange regulations by governmental authorities might limit the trading of forward contracts on currencies.

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.

Swaps. The risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make or, in the case of the other party to a swap defaulting, the net amount of payments that the Fund is contractually entitled to receive. If the Fund sells a credit default swap, however, the risk of loss may be the entire notional amount of the swap.

Some swaps are now executed through an organized exchange or regulated facility and cleared through a regulated clearing organization. The absence of an organized exchange or market for swap transactions may result in difficulties in trading and valuation, especially in the event of market disruptions. The use of an organized exchange or market for swap transactions is expected to result in swaps being easier to trade or value, but this may not always be the case.

Foreign and Emerging Market Risk. Foreign securities, including those issued by foreign governments, 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, 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 and may adversely affect the Fund’s performance.

5 Short Duration Bond Portfolio (Class I)

Interest Rate Risk.The Fund’s yield and share price will fluctuate in response to changes in interest rates. 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.

Leverage Risk. Leverage amplifies changes in the Fund’s net asset value and may make the Fund more volatile. Derivatives and when-issued and forward-settling securities may create leverage and can result in losses to the Fund that exceed the amount originally invested and may accelerate the rate of losses. There can be no assurance that the Fund’s use of any leverage will be successful. The Fund’s investment exposure can exceed its net assets, sometimes by a significant amount.

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 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.

Mortgage- and Asset-Backed Securities Risk. The value of mortgage- and asset-backed securities, including collateralized mortgage instruments, will be influenced by the factors affecting the housing market or the assets underlying the securities. These securities tend to be more sensitive to changes in interest rates than other types of debt securities. In addition, investments in mortgage- and asset-backed securities may be subject to prepayment risk and extension risk, call risk, credit risk, valuation risk, and illiquid investment risk, sometimes to a higher degree than various other types of debt securities. These securities are also subject to the risk of default on the underlying mortgages or assets, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security’s value.

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

6 Short Duration Bond Portfolio (Class I)

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.

Prepayment and Extension Risk. The Fund’s performance could be affected if borrowers pay back principal on certain debt securities, such as mortgage- or asset-backed securities, before (prepayment) or after (extension) the market anticipates such payments, shortening or lengthening their duration. Due to a decline in interest rates or an excess in cash flow into the issuer, a debt security might be called or otherwise converted, prepaid or redeemed before maturity. As a result of prepayment, the Fund may have to reinvest the proceeds in an investment offering a lower yield, may not benefit from any increase in value that might otherwise result from declining interest rates, and may lose any premium it paid to acquire the security. Conversely, rising market interest rates generally result in slower payoffs or extension, which effectively increases the duration of certain debt securities, heightening interest rate risk and increasing the magnitude of any resulting price declines.

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. 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. Some countries, including the U.S., have in recent years adopted more protectionist trade policies. The rise in protectionist trade policies, changes to some major international trade agreements and the potential for changes to others, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. Russia’s assertion of its influence in its surrounding region, including potential actions in Ukraine, increases the likelihood of additional sanctions by the U.S. and other countries, which may cause volatility in the markets.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty, and there may be a further increase in public debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Governments and central banks have moved to limit the potential negative economic effects of the COVID-19 pandemic with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, perhaps in response to indications of increasing inflation. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives or their alteration or cessation.

The impact of the pandemic has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model, and has disrupted the supply chains that many businesses depend on. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that appears to be changing. Increased regulation may impose added costs on the Fund and its service providers for monitoring and compliance, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time.

Climate Change. There is widespread concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes tied to concerns about climate change could adversely affect the value of certain land and the viability of certain industries.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

LIBOR Transition. Certain financial contracts around the world specify rates that are based on the London Interbank Offered Rate (LIBOR), which is produced daily by averaging the rates for inter-bank lending reported by a number of banks. As previously announced by the United Kingdom’s Financial Conduct Authority, most maturities and currencies of LIBOR were phased out at the end of 2021, with the remaining ones to be phased out on June 30, 2023. There are risks that the financial services industry will not have a suitable substitute in place by that time and that there will not be time to perform the substantial work necessary to revise the many existing contracts that rely on LIBOR. The transition process, or a failure of the industry to transition properly, might lead to increased volatility and illiquidity in markets that currently rely on LIBOR. It also could lead to a reduction in the value of some LIBOR-based investments and reduce the effectiveness of new hedges placed against existing LIBOR-based instruments. New York has passed legislation to ease the transition from LIBOR and federal LIBOR transition relief legislation has been proposed, but there is no assurance whether or when such legislation will be enacted or if it will adequately address all issues or be subject to litigation.

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. A general rise in interest rates has the potential to cause investors to move out of fixed income securities on a large scale, which may increase redemptions from mutual funds that hold large amounts of fixed income securities; such a move, coupled with a reduction in the ability or willingness of dealers and other institutional investors to buy or hold fixed income securities, may result in decreased liquidity and increased volatility in the fixed income markets.

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.

Sovereign Debt Risk. Sovereign debt securities are subject to the risk that a governmental entity may delay or refuse to pay interest or principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the size of the governmental entity’s debt position in relation to the economy, its policy toward international lenders or the failure to put in place economic reforms required by multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There may be no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. Sovereign debt risk is increased for emerging market issuers.

U.S. Government Securities Risk. Although the Fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market prices of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Securities not backed by the full faith and credit of the U.S. Treasury carry at least some risk of non-payment or default.

Variable and Floating Rate Instruments Risk. The market prices of instruments with variable and floating interest rates are generally less sensitive to interest rate changes than are the market prices of instruments with fixed interest rates. Variable and

8 Short Duration Bond Portfolio (Class I)

floating rate instruments may decline in value if market interest rates or interest rates paid by such instruments do not move as expected. Certain types of floating rate instruments, such as interests in bank loans, may be subject to greater liquidity risk than other debt securities.

When-Issued and Forward-Settling Securities Risk. When-issued and forward-settling securities can have a leverage-like effect on the Fund, which can increase fluctuations in the Fund’s share price; may cause the Fund to liquidate positions when it may not be advantageous to do so, in order to satisfy its purchase obligations; and are subject to the risk that the security will not be issued or that a counterparty will fail to complete the sale or purchase of the security, in which case the Fund may lose the opportunity to purchase or sell the security at the agreed upon price.

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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 mutual funds to calculate their NAVs. 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.

Descriptions of Certain Practices and Security Types

Derivatives. A derivative is generally a financial contract the value of which depends on, or is derived from, changes in the value of one or more “reference instruments,” such as underlying assets (including securities), reference rates, indices or events. Derivatives may relate to stocks, bonds, credit, interest rates, commodities, currencies or currency exchange rates, or related indices. A derivative may also contain leverage to magnify the exposure to the reference instrument. Derivatives may be traded on organized exchanges and/or through clearing organizations, or in private transactions with other parties in the over-the-counter (“OTC”) market with a single dealer or a prime broker acting as an intermediary with respect to an executing dealer. Derivatives may be used for hedging purposes and non-hedging (or speculative) purposes. Some derivatives require one or more parties to post “margin,” which means that a party must deposit assets with, or for the benefit of, a third party, such as a futures commission merchant, in order to initiate and maintain the derivatives position. Margin is typically adjusted daily, and adverse market movements may require a party to post additional margin.

Forward Foreign Currency Contracts (“Forward Contracts”). A forward contract is a contract for the purchase or sale of a specific foreign currency at a future date at a fixed price. Forward contracts are not required to be traded on organized exchanges or cleared through regulated clearing organizations.

Futures. A futures contract is a standardized agreement to buy or sell a set quantity of an underlying asset at a future date, or to make or receive a cash payment based on the value of a securities index or other reference instrument at a future date.

Swaps. In a standard swap transaction, two parties agree to exchange one or more payments based, for example, on the returns (or differentials in rates of return) earned or realized on particular predetermined reference instruments. Swap transactions generally may be used to obtain exposure to a reference instrument without owning or taking physical custody of the reference instrument and generally do not involve delivery of the notional amount of the agreement. Swaps have historically been OTC instruments; however, recent legislation requires many swaps to be executed through an organized exchange or regulated facility and cleared through a regulated clearing organization.

There are various types of swaps including, but not limited to, the following: interest rate swaps (exchanging a floating interest rate for a fixed interest rate); total return swaps (exchanging a floating interest rate for the total return of a reference instrument); credit default swaps (buying or selling protection against certain designated credit events); and options on swaps (“swaptions”) (options to enter into a swap agreement).

Emerging Market Countries. Emerging market countries are generally considered to be those countries whose economies are less developed than the economies of countries such as the United States or most nations in Western Europe.

Fixed Income Securities. Debt securities may consist of fixed and floating rate obligations of various credit quality and duration and may be issued by: corporate entities; trusts; domestic issuers, including securities issued or guaranteed as to principal or interest by the U.S. government or any of its agencies or instrumentalities; foreign issuers, including in emerging markets, and including foreign governments and supranational entities; and municipal issuers, including within the U.S. and its territories. Such obligations may include: bonds, loans, inflation-linked debt securities, when-issued and forward-settling securities, commercial paper, mortgage-backed securities and other asset-backed securities, and hybrid securities (including convertible securities).

Lower-Rated Debt Securities. Lower-rated debt securities (commonly known as “junk bonds”) typically offer investors higher yields than other fixed income securities. The higher yields are usually justified by the weaker credit profiles of these issuers as compared to investment grade issuers. Lower-rated debt securities may include debt obligations of all types issued by U.S. and non-U.S. corporate and governmental entities, including bonds, debentures and notes, loan interests and preferred stocks that have priority over any other class of stock of the entity as to the distribution of assets or the payment of dividends.

12

Collateralized Debt Obligations Risk. CDOs, which include collateralized loan obligations (CLOs), issue classes or “tranches” of securities that vary in risk and yield and may experience substantial losses due to interest rate fluctuations, actual defaults, collateral defaults, disappearance of subordinate tranches, market anticipation of defaults, and investor aversion to CDO securities as a class. CDOs carry risks including, but not limited to, (i) the possibility that distributions from the underlying debt securities will not be adequate to make interest or other payments, (ii) the quality of the underlying debt securities may decline in value or default, particularly during periods of economic downturn, (iii) the Fund may invest in CDOs that are subordinate to other classes of securities, (iv) the investment return could be significantly different than those predicted by financial models; (v) the risk of forced “fire sale” liquidation due to technical defaults such as coverage test failures, (vi) the manager of the CDO may perform poorly, and (vii) the complex structure may produce disputes with the issuer or unexpected investment results. The risks of investing in CDOs depend largely on the quality and type of the underlying debt, which may include loans, bonds and mortgages, and the tranche of the CDO in which the Fund invests. In addition, CDOs that obtain their exposure through derivative instruments entail the additional risks associated with such instruments. CDOs can be difficult to value, may at times be illiquid, may be highly leveraged (which could make them highly volatile), and may produce unexpected investment results due to their complex structure. In addition, CDOs involve many of the same risks of investing in debt securities and asset-backed securities including, but not limited to, interest rate risk, credit risk, liquidity risk, and valuation risk.

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, factors affecting an issuer directly (such as management changes, labor relations, collapse of key suppliers or customers, or material changes in overhead), factors affecting the industry in which a particular issuer operates (such as competition or technological advances) and changes in general social, economic or political conditions can increase the risk of default by an issuer, which may affect a security’s credit quality or value.

Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk. In addition, lower credit quality may lead to greater volatility in the price of a security and may negatively affect a security’s liquidity. Ratings represent a rating agency’s opinion regarding the quality of the security and are not a guarantee of quality and do not protect against a decline in the value of a security. A downgrade or default affecting any of the Fund’s securities could affect the Fund’s performance. In addition, rating agencies may fail to make timely changes to credit ratings in response to subsequent events and a rating may become stale in that it fails to reflect changes in an issuer’s financial condition. The credit quality of a security or instrument can deteriorate suddenly and rapidly, which may negatively impact its liquidity and value. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit, or bond insurance). Entities providing credit or liquidity support also may be affected by credit risk. Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security’s value due to changes in market conditions.

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. Domestic issuers that hold substantial foreign assets may be similarly affected. Currency exchange rates may fluctuate in response to factors external to a country’s economy, which makes the forecasting of currency market movements extremely difficult. Currency exchange rates may fluctuate significantly over short periods of time and can be affected unpredictably by various factors, including investor perception of a country’s economy and changes in interest rates; intervention, or failure to intervene, by U.S. or foreign governments, central banks, or supranational entities, such as the International Monetary Fund; or by currency controls or political developments in the U.S. or abroad. To the extent the Fund invests or hedges based on the perceived relationship between two currencies, there is a risk that the correlation between those currencies may not behave as anticipated.

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, which can magnify the impact of a decline in the value of the reference instrument underlying the derivative, and the Fund could lose more than the amount it invests. Derivatives can have the potential for unlimited losses, for example, where the Fund may be called upon to deliver a security it does not own. 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, and the reference instrument may not perform as anticipated. 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

13

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 may involve fees, commissions, or other costs that may reduce the Fund’s gains or exacerbate losses from the derivatives. In addition, the Fund’s use of derivatives may have different tax consequences for the Fund than an investment in the reference instruments, and those differences may increase the amount and affect the timing of income recognition and character of taxable distributions payable to shareholders. Thus, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirements. Certain aspects of the regulatory treatment of derivative instruments, including federal income tax, are currently unclear and may be affected by changes in legislation, regulations, or other legally binding authority. In October 2020, the SEC adopted Rule 18f-4 under the 1940 Act which will regulate the use of derivatives for certain funds registered under the Investment Company Act (‘‘Rule 18f-4’’). Unless the Fund qualifies as a ‘‘limited derivatives user’’ as defined in Rule 18f-4, Rule 18f-4 would, among other things, require the Fund to establish a comprehensive derivatives risk management program, to comply with certain value-at-risk based leverage limits, to appoint a derivatives risk manager and to provide additional disclosure both publicly and to the SEC regarding its derivatives positions. If the Fund qualifies as a limited derivatives user, Rule 18f-4 requires the Fund to have policies and procedures to manage its aggregate derivatives risk. These requirements could have an impact on the Fund, including a potential increase in cost to enter into derivatives transactions. The full impact of Rule 18f-4 on the Fund remains uncertain, however, due to the compliance timeline within Rule 18f-4, it is unlikely that the Fund will be required to fully comply with the requirements until August 2022.

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. Counterparty risk may arise because of market activities and developments, the counterparty’s financial condition (including financial difficulties, bankruptcy, or insolvency), or other reasons. Not all derivative transactions require a counterparty to post collateral, which may expose the Fund to greater losses in the event of a default by a counterparty. Counterparty risk is generally thought to be greater with OTC derivatives than with derivatives that are exchange traded or centrally cleared. However, derivatives that are traded on organized exchanges and/or through clearing organizations involve the possibility that the futures commission merchant or clearing organization will default in the performance of its obligations.

When the Fund uses derivatives, it will likely be required to provide margin or collateral and/or segregate cash or other liquid assets; 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 and/or segregate assets could limit the Fund's ability to pursue other opportunities as they arise. Segregated assets are not available to meet redemptions. The amount of assets required to be segregated will depend on the type of derivative the Fund uses and the nature of the contractual arrangement. If the Fund is required to segregate assets equal to only the current market value of its obligation under a derivative, the Fund may be able to use derivatives to a greater extent, which would increase the degree of leverage the Fund could undertake through derivatives and otherwise, than if it were required to segregate assets equal to the full notional value of such derivative. Derivatives that have margin requirements involve the risk that if the Fund has insufficient cash or eligible margin securities to meet daily variation margin requirements, it may have to sell securities or other instruments from its portfolio at a time when it may be disadvantageous to do so. The Fund normally will remain obligated to meet margin requirements until a derivatives position is closed.

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.

Although the Fund may use derivatives to attempt to hedge against certain risks, the hedging instruments may not perform as expected and could produce losses.

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

Forward Contracts. There are no limitations on daily price movements of forward contracts. Changes in foreign exchange regulations by governmental authorities might limit the trading of forward contracts on currencies. There have been periods during which certain counterparties have refused to continue to quote prices for forward contracts or have quoted prices with an unusually wide spread (the difference between the price at which the counterparty is prepared to buy and the price at which it is prepared to sell).

Futures. There can be no assurance that, at all times, a liquid market will exist for offsetting a futures contract that the Fund has previously bought or sold and this may result in the inability to close a futures position when desired. This could be the case if, for example, a futures price has increased or decreased by the maximum allowable daily limit and there is no buyer (or seller) willing to purchase (or sell) the futures contract that the Fund needs to sell (or buy) at that

14

limit price. 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.

Swaps. Swap transactions generally do not involve delivery of reference instruments or payment of the notional amount of the contract. Accordingly, the risk of loss with respect to swaps generally is limited to the net amount of payments that the Fund is contractually obligated to make or, in the case of the other party to a swap defaulting, the net amount of payments that the Fund is contractually entitled to receive. If the Fund sells a credit default swap, however, the risk of loss may be the entire notional amount of the swap.

Some swaps are now executed through an organized exchange or regulated facility and cleared through a regulated clearing organization. The absence of an organized exchange or market for swap transactions may result in difficulties in trading and valuation, especially in the event of market disruptions. The use of an organized exchange or market for swap transactions is expected to result in swaps being easier to trade or value, but this may not always be the case.

Foreign and Emerging Market Risk. Foreign securities, including those issued by foreign governments, 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, corporate disclosure, governance, and legal standards. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities. In addition, key information about the issuer, the markets or the local government or economy may be unavailable, incomplete, or inaccurate. 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, securities issued by U.S. entities with substantial foreign operations may involve risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates. 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, and may suffer from extreme and volatile debt burdens or inflation rates. 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. Shareholder claims and legal remedies that are common in the United States may be difficult or impossible to pursue in many emerging market countries. In addition, due to jurisdictional limitations, matters of comity and various other factors, U.S. authorities may be limited in their ability to bring enforcement actions against non-U.S. companies and non-U.S. persons in certain emerging market countries. Most foreign and emerging market companies are not subject to the uniform accounting, auditing and financial reporting requirements applicable to issuers in the United States, which may impact the availability and quality of information about foreign and emerging market issuers. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Additionally, in times of market stress, regulatory authorities of different emerging market countries may apply varying techniques and degrees of intervention, which can have an effect on prices. 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

15

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.

In addition, foreign markets may perform differently than the U.S. market. Over a given period of time, foreign securities may underperform U.S. securities—sometimes for years. The Fund could also underperform if it invests in countries or regions whose economic performance falls short. To the extent that the Fund invests a portion of its assets in one country, state, region or currency, an adverse economic, business or political development may affect the value of the Fund’s investments more than if its investments were not so invested.

The effect of economic instability on specific foreign markets or issuers may be difficult to predict or evaluate. Some national economies continue to show profound instability, which may in turn affect their international trading and financial partners or other members of their currency bloc.

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 and may adversely affect the Fund’s performance.

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. Interest rates may change in response to the supply and demand for credit, changes to government monetary policy and other initiatives, inflation rates, and other factors. Debt securities have varying levels of sensitivity to changes in interest rates. Typically, the longer the maturity (i.e., the term of a debt security) or duration (i.e., a measure of the sensitivity of a debt security to changes in market interest rates, based on the entire cash flow associated with the security) of a debt security, the greater the effect a change in interest rates could have on the security’s price. For example, if interest rates increase by 1%, a debt security with a duration of two years will decrease in value by approximately 2%. Thus, the sensitivity of the Fund's debt securities to interest rate risk will increase with any increase in the duration of those securities. Short-term securities tend to react to changes in short-term interest rates, and long-term securities tend to react to changes in long-term interest rates. Short-term and long-term interest rates, and interest rates in different countries, do not necessarily move in the same direction or by the same amount. The link between interest rates and debt security prices tends to be weaker with lower-rated debt securities than with investment grade debt securities.

Issuer-Specific Risk. An individual security may be more volatile, and may perform differently, than the market as a whole. The value of an issuer’s securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer, or changes in government regulations affecting the issuer or the competitive environment. Certain unanticipated events, such as natural disasters, may have a significant adverse effect on the value of an issuer’s securities.

Leverage Risk. Leverage amplifies changes in the Fund’s net asset value and may make the Fund more volatile. Derivatives and when-issued and forward-settling securities may create leverage and can result in losses to the Fund that exceed the amount originally invested and may accelerate the rate of losses. For certain instruments or transactions that create leverage, or have embedded leverage, relatively small market fluctuations may result in large changes in the value of such investments. In addition, the costs that the Fund pays to engage in these practices are additional costs borne by the Fund and could reduce or eliminate any net investment profits. Unless the profits from engaging in these practices exceed the costs of engaging in these practices, the use of leverage will diminish the investment performance of the Fund compared with what it would have been had the Fund not used leverage. There can be no assurance that the Fund’s use of any leverage will be successful. The Fund’s investment exposure can exceed its net assets, sometimes by a significant amount. When the Fund uses leverage or utilizes certain of these practices, it may need to dispose of some of its holdings at unfavorable times or prices in order to satisfy its obligations or to comply with certain asset coverage requirements.

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility or adverse investor perception. 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. Market

16

participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. 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 may be less liquid and also may require a greater degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, and may carry higher transaction costs. In particular, these securities may be issued by smaller companies or by highly indebted companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal. 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. Such securities are susceptible to such a default or decline in market value due to real or perceived adverse economic and business developments relating to the issuer, the industry in general, market interest rates and market liquidity. 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. Where it deems it appropriate and in the best interests of Fund shareholders, the Fund may incur additional expenses to seek recovery on a defaulted security and/or to pursue litigation to protect the Fund’s investment.

The credit rating of a security may not accurately reflect the actual credit risk associated with such a security. 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.

Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of such securities, especially in a thinly traded or illiquid market. To the extent the Fund owns or may acquire illiquid or restricted lower-rated debt securities or unrated debt securities of comparable quality, these securities may involve special registration responsibilities, liabilities, costs, and liquidity and valuation difficulties.

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. Changes in the financial condition of a single issuer may impact a market as a whole. 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. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

Mortgage- and Asset-Backed Securities Risk. The value of mortgage- and asset-backed securities, including collateralized mortgage instruments, will be influenced by the factors affecting the housing market or the assets underlying the securities. These securities differ from more traditional debt securities because the principal is paid back over the life of the security rather than at the security’s maturity; however, principal may be repaid early if a decline in interest rates causes many borrowers to refinance (known as prepayment risk), or repaid more slowly if a rise in rates causes refinancings to slow down (known as extension risk). Thus, they tend to be more sensitive to changes in interest rates than other types of debt securities and as a result, these securities may exhibit additional volatility during periods of interest rate turmoil. In addition, investments in mortgage- and asset-backed securities may be subject to call risk, credit risk, valuation risk, and illiquid investment risk, sometimes to a higher degree than various other types of debt securities. These securities are also subject to the risk of default on the underlying mortgages or assets, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security’s value. Further, such securities may have credit support, the utility of which could be negatively affected by such conditions as well.

17

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 (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and 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.

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 and to the allocation of its assets among 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 because of, for example, the temporary unavailability of certain index securities in the secondary market or discrepancies between the ETF and the index with respect to the weighting of securities or the number of stocks held. A passively managed ETF may not be permitted to sell poorly performing stocks that are included in its index.

Prepayment and Extension Risk. The Fund’s performance could be affected if borrowers pay back principal on certain debt securities, such as mortgage- or asset-backed securities, before (prepayment) or after (extension) the market anticipates such payments, shortening or lengthening their duration. Due to a decline in interest rates or an excess in cash flow into the issuer, a debt security might be called or otherwise converted, prepaid or redeemed before maturity. As a result of prepayment, the Fund may have to reinvest the proceeds in an investment offering a lower yield, may not benefit from any increase in value that might otherwise result from declining interest rates, and may lose any premium it paid to acquire the security. Prepayments could also create capital gains tax liability in some instances. Conversely, rising market interest rates generally result in slower payoffs or extension, which effectively increases the duration of certain debt securities, heightening interest rate risk and increasing the magnitude of any resulting price declines. If the Fund’s investments are locked in at a lower interest rate for a longer period of time, the Fund may be unable to capitalize on securities with higher interest rates or wider spreads.

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. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and 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. A security that was liquid at the time of purchase may subsequently become illiquid. In addition, transaction costs may be higher for private placements and other restricted securities. The Fund may have to bear the expense of registering such securities for sale and there may be substantial delays in effecting the registration. If,

18

during such a delay, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed at the time it decided to seek registration of the securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security, so it may be less able to anticipate a loss. Also, if Fund management receives material non-public information about the issuer, the Fund may, as a result, be legally prohibited from selling the securities.

Recent Market Conditions. Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. Outbreaks such as the novel coronavirus, COVID-19, or other similarly infectious diseases may have material adverse impacts on the Fund. 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. The impact of this virus, and other epidemics and/or pandemics that may arise in the future, has negatively affected and may continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. The impact of any outbreak may last for an extended period of time. The current pandemic has accelerated trends toward working remotely and shopping on-line, which may negatively affect the value of office and commercial real estate and companies that have been slow to transition to an on-line business model. The travel, hospitality and public transit industries may suffer long-term negative effects from the pandemic and resulting changes to public behavior.

Governments and central banks have moved to limit these negative economic effects with interventions that are unprecedented in size and scope and may continue to do so, but the ultimate impact of these efforts is uncertain. Governments’ efforts to limit potential negative economic effects of the pandemic may be altered, delayed, or eliminated at inopportune times for political, policy or other reasons. The impact of infectious diseases may be greater in countries that do not move effectively to control them, which may occur for political reasons or because of a lack of health care or economic resources. Health crises caused by the recent coronavirus outbreak may exacerbate other pre-existing political, social and economic risks in certain countries. Although effective vaccines are available, it may be many months before vaccinations are sufficiently widespread in many countries to allow the restoration of full economic activity. The failure to control the coronavirus in less developed countries may impact the economies of more developed countries.

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. Following Russia’s actions, various governments, including the United States, have issued broad-ranging economic sanctions against Russia, including, among other actions, a prohibition on doing business with certain Russian companies, large financial institutions, officials and oligarchs; the removal by certain countries and the European Union of selected Russian banks from the Society for Worldwide Interbank Financial Telecommunications (“SWIFT”), the electronic banking network that connects banks globally; and restrictive measures to prevent the Russian Central Bank from undermining the impact of the sanctions. The current events, including sanctions and the potential for future sanctions, including any impacting Russia’s energy sector, and other actions, and Russia’s retaliatory responses to those sanctions and actions, may continue to adversely impact the Russian and Ukrainian economies and may result in the further decline of the value and liquidity of Russian and Ukrainian securities, a continued weakening of the ruble and hryvnia and continued exchange closures, and may have other adverse consequences on the Russian and Ukrainian economies that could impact the value of these investments and impair the ability of a Fund to buy, sell, receive or deliver those securities. Moreover, those events have, and could continue to have, an adverse effect on global markets performance and liquidity, thereby negatively affecting the value of a Fund’s investments beyond any direct exposure to Russian and Ukrainian issuers. 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 a 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 and there may be a further increase in the amount of debt due to the economic effects of the COVID-19 pandemic and ensuing economic relief and public health measures. Interest rates have been unusually low in recent years in the U.S. and abroad. It is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes, whether brought about by government policy makers, perhaps in response to indications of increasing inflation, or by dislocations in world markets. For example, because investors may buy equity securities or other investments with borrowed money, a significant increase in interest rates may cause a decline in the markets for those investments. In addition, ongoing inflation pressures from tight labor markets and supply chain disruptions could cause a material increase in interest rates and/or negatively impact companies. Also, regulators have expressed concern that rate increases may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, rising interest rates may present a greater risk than has historically been the case due to the current period of relatively low rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of

19

correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses. 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.

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. A rise in protectionist trade policies, tariff “wars,” changes to some major international trade agreements and the potential for changes to others, and campaigns to “buy American,” could affect international trade and the economies of many nations in ways that cannot necessarily be foreseen at the present time.

Markets have been sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future. China’s economy, which has been sustained in recent years largely through a debt-financed housing boom, may be approaching the limits of that strategy and may experience a significant slowdown as a result of debt that cannot be repaid. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

In December 2020, the United Kingdom (“UK”) and the European Union (“EU”) signed a Trade and Cooperation Agreement (“TCA”) to delineate the terms on which the UK left the EU. The TCA did little to address financial services and products provided by UK entities to customers in the EU, leaving the future of such services and products uncertain. New trading rules have disrupted the cross-border flow of products and supplies for many businesses; it remains to be seen whether these will be smoothed out with the passage of time or cause long-term damage to affected businesses. There is some uncertainty as to whether dislocations in the UK’s economy are mainly the result of COVID-19 (as the government claims) or the result of the country having left the EU.

Over the past several years, the U.S. has moved away from tighter legislation and regulation impacting businesses and the financial services industry. There is a strong potential for materially increased regulation in the future, as well as higher taxes and/or taxes restructured to incentivize different activities. These changes, should they occur, may impose added costs on the Fund and its service providers, and affect the businesses of various portfolio companies, in ways that cannot necessarily be foreseen at the present time. 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.

Climate Change. There is increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, a change in weather patterns, including an increase in powerful storms and large wildfires, and/or a climate-driven increase in flooding could cause properties to lose value or become unmarketable altogether. Unlike previous declines in the real estate market, properties in affected zones may not ever recover their value. The U.S. administration appears concerned about the climate change problem and is focusing regulatory and public works projects around those concerns. Regulatory changes and divestment movements tied to concerns about climate change could adversely affect the value of certain land and the viability of industries whose activities or products are seen as accelerating climate change.

Losses related to climate change could adversely affect corporate issuers and mortgage lenders, the value of mortgage-backed securities, the bonds of municipalities that depend on tax or other revenues and tourist dollars generated by affected properties, and insurers of the property and/or of corporate, municipal or mortgage-backed securities. Since property and security values are driven largely by buyers’ perceptions, it is difficult to know the time period over which these market effects might unfold.

LIBOR Transition. Certain financial contracts around the world specify rates that are based on the London Interbank Offered Rate (LIBOR), which is produced daily by averaging the rates for inter-bank lending reported by a number of banks. As previously announced by the United Kingdom’s Financial Conduct Authority, most maturities and currencies of LIBOR were phased out at the end of 2021, with the remaining ones to be phased out on June 30, 2023. There are risks that the financial services industry will not have a suitable substitute in place by that time and that there will not be time to perform the substantial work necessary to revise the many existing contracts that rely on LIBOR. The transition process, or a failure of the industry to transition properly, might lead to increased volatility and illiquidity in markets that currently rely on LIBOR. It also could lead to a reduction in the value of some LIBOR-based investments and reduce the effectiveness of new hedges placed against existing LIBOR-based instruments. New York has passed legislation to ease the transition from LIBOR and federal LIBOR transition relief legislation has been proposed, but there is no assurance whether or when such legislation will be enacted or if it will adequately address all issues or be subject to litigation.

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

20

the Fund, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

A general rise in interest rates has the potential to cause investors to move out of fixed income securities on a large scale, which may increase redemptions from mutual funds that hold large amounts of fixed income securities; such a move, coupled with a reduction in the ability or willingness of dealers and other institutional investors to buy or hold fixed income securities, may result in decreased liquidity and increased volatility in the fixed income markets.

Risk Management. Management undertakes certain analyses with the intention of identifying particular types of risks and reducing the Fund’s exposure to them. However, risk is an essential part of investing, and the degree of return an investor might expect is often tied to the degree of risk the investor is willing to accept. By its very nature, risk involves exposure to the possibility of adverse events. Accordingly, no risk management program can eliminate the Fund’s exposure to such events; at best, it may only reduce the possibility that the Fund will be affected by adverse events, and especially those risks that are not intrinsic to the Fund’s investment program. While the prospectus describes material risk factors associated with the Fund’s investment program, there is no assurance that as a particular situation unfolds in the markets, management will identify all of the risks that might affect the Fund, rate their probability or potential magnitude correctly, or be able to take appropriate measures to reduce the Fund’s exposure to them. Measures taken with the intention of decreasing exposure to identified risks might have the unintended effect of increasing exposure to other risks.

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 one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market 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. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

Sovereign Debt Risk. Sovereign debt securities are subject to the risk that a governmental entity may delay or refuse to pay interest or principal on its sovereign debt, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, the size of the governmental entity’s debt position in relation to the economy, its policy toward international lenders or the failure to put in place economic reforms required by multilateral agencies. If a governmental entity defaults, it may ask for more time in which to pay or for further loans. There may be no legal process for collecting sovereign debt that a government does not pay nor are there bankruptcy proceedings through which all or part of the sovereign debt that a governmental entity has not repaid may be collected. Sovereign debt risk is increased for emerging market issuers. Certain emerging market or developing countries are among the largest debtors to commercial banks and foreign governments. At times, certain emerging market countries have declared moratoria on the payment of principal and interest on external debt. Certain emerging market countries have experienced difficulty in servicing their sovereign debt on a timely basis that led to defaults and the restructuring of certain indebtedness.

U.S. Government Securities Risk. Although the Fund may hold securities that carry U.S. government guarantees, these guarantees do not extend to shares of the Fund itself and do not guarantee the market prices of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed by the issuer’s right to borrow from the U.S. Treasury, while others are backed only by the credit of the issuing agency or instrumentality. These securities carry at least some risk of non-payment or default by the issuer. The maximum potential liability of the issuers of some U.S. government securities may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future.

In recent periods, the values of U.S. government securities have been affected substantially by increased demand for them around the world. Increases or decreases in the demand for U.S. government securities may occur at any time and may result in increased volatility in the values of those securities. In recent years, credit rating agencies have shown some concern about whether the U.S. government has the political will necessary to service all of its outstanding and expected future debt, and some have adjusted their ratings or outlook for U.S. government debt accordingly. These developments, and the factors underlying them, could cause an increase in interest rates and borrowing costs, which may negatively impact both the perception of credit risk associated with the debt securities issued by the U.S. and the government's ability to access the debt markets on favorable terms. In addition, these developments could create broader financial turmoil and uncertainty, which could increase volatility in both stock and bond markets. These events could result in significant adverse impacts on issuers of securities held by the Fund.

21

Valuation Risk. The price at which the Fund sells any particular investment may differ from the Fund’s valuation of 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 some investments, SEC rules and applicable accounting protocols may require the Fund to value these 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 closing price and from the prices used by other mutual funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have received if the Fund had not held fair-valued securities or had used a different valuation methodology. The value of foreign securities, certain futures and fixed income securities, and currencies, as applicable, may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. 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.

Variable and Floating Rate Instruments Risk. The market prices of instruments with variable and floating interest rates are generally less sensitive to interest rate changes than are the market prices of instruments with fixed interest rates. Variable and floating rate instruments may decline in value if market interest rates or interest rates paid by such instruments do not move as expected. Conversely, variable and floating rate instruments will not generally rise in value if market interest rates decline. Thus, investing in variable and floating rate instruments generally allows less opportunity for capital appreciation and depreciation than investing in instruments with a fixed interest rate. Certain types of floating rate instruments, such as interests in bank loans, may be subject to greater liquidity risk than other debt securities.

Certain variable and floating rate instruments have an interest rate floor feature, which prevents the interest rate payable by the instrument from dropping below a specified level as compared to a reference interest rate (the “reference rate”), such as SOFR. Such a floor protects the Fund from losses resulting from a decrease in the reference rate below the specified level. However, if the reference rate is below the floor, there will be a lag between a rise in the reference rate and a rise in the interest rate payable by the instrument, and the Fund may not benefit from increasing interest rates for a significant period of time. Rates on certain variable rate instruments typically only reset periodically. As a result, changes in prevailing interest rates, particularly sudden and significant changes, can cause some fluctuations in the Fund’s value to the extent that it invests in variable rate instruments.

When-Issued and Forward-Settling Securities Risk. When-issued and forward-settling securities (such as to-be-announced (TBA) mortgage-backed securities) involve a commitment by the Fund to purchase or deliver securities at a later date. Because the Fund is committed to buying them at a certain price, any change in the value of these securities, even prior to their issuance, affects the Fund’s share value. Accordingly, the purchase of such securities involves a risk of loss if the value of the security to be purchased declines before the settlement date. When-issued and forward-settling securities can have a leverage-like effect on the Fund, which can increase fluctuations in the Fund’s share price. The Fund will segregate appropriate liquid assets having a market value at least equal to the amount of its purchase commitments. When-issued and forward-settling securities may cause the Fund to liquidate positions when it may not be advantageous to do so, in order to satisfy its purchase obligations. When-issued and forward-settling securities also are subject to the risk that the security will not be issued or that a counterparty will fail to complete the sale or purchase of the security. If this occurs, the Fund may lose the opportunity to purchase or sell the security at the agreed upon price and may forgo any gain in the security’s price. The Fund may sell securities it has committed to purchase before those securities are delivered to the Fund on the settlement date. In addition, the purchase of mortgage-backed securities on a TBA basis may result in a Fund incurring increased prepayment risks because the underlying mortgages may be less favorable than anticipated by the Fund.

Information about Additional Risks and Other Practices

As discussed in the Fund’s Statement of Additional Information, the Fund may engage in certain practices and invest in certain securities in addition to those described as its “principal investment strategies” in the Fund Summary section. For example, should the Fund engage in borrowing or securities lending, it will be subject to the additional risks associated with these practices.

Borrowing money or securities lending would create investment leverage, meaning that certain gains or losses would be amplified, increasing share price movements.

As part of its liquidity management practices, including for cash management purposes or to facilitate short-term liquidity, the Fund may invest in reverse repurchase agreements. In a reverse repurchase agreement, the Fund sells portfolio securities to another party, such as a bank or broker-dealer, in return for cash and agrees to repurchase the securities at an agreed-upon price and date, which reflects an interest payment to that party. Reverse repurchase agreements involve the risk that the other party will fail to

22

return the securities in a timely manner, or at all, which may result in losses to the Fund. The Fund could lose money if it is unable to recover the securities and the value of the cash collateral held by the Fund is less than the value of the securities. These events could also trigger adverse tax consequences to the Fund. Reverse repurchase agreements also involve the risk that the market value of the securities sold will decline below the price at which the Fund is obligated to repurchase them. Reverse repurchase agreements may be viewed as a form of borrowing by the Fund. When the Fund enters into a reverse repurchase agreement, any fluctuations in the market value of either the securities transferred to another party or the securities in which the proceeds may be invested would affect the market value of the Fund’s assets. During the term of the agreement, the Fund may also be obligated to pledge additional cash and/or securities in the event of a decline in the fair value of the transferred security. The Manager monitors the creditworthiness of counterparties to reverse repurchase agreements.

In addition, the Fund may be an investment option for a Neuberger Berman mutual fund that is managed as a “fund of funds.” As a result, from time to time, the Fund may experience relatively large redemptions or investments and could be required to sell securities or to invest cash at a time when it is not advantageous to do so.

In anticipation of adverse or uncertain market, economic, political, or other temporary conditions, including during periods of high cash inflows or outflows, the Fund may temporarily depart from its goal and use a different investment strategy (including leaving a significant portion of its assets uninvested) for defensive purposes. Doing so could help the Fund avoid losses, but may mean lost opportunities. In addition, in doing so different factors could affect the Fund’s performance and the Fund may not achieve its goal. In addition, to the extent the Fund is undergoing a transition (such as a change in strategy, rebalancing, reorganization, liquidation or experiencing large inflows or outflows) or takes a temporary defensive position, it may deviate from its principal investment strategies during such period.

The Fund may change its goal without shareholder approval, although it does not currently intend to do so.

Please see the Statement of Additional Information for more information.

Because the Fund is offered to different insurance companies, and for different types of variable contracts—annuities and life insurance—and to qualified plans, groups with different interests will share the Fund. Due to differences of tax treatment and other considerations among these shareholders, it is possible (although not likely) that the interests of the shareholders might sometimes be in conflict. For these reasons, the trustees of the Fund watch for the existence of any material irreconcilable conflicts and will determine what action, if any, should be taken in the event of a conflict. If there is a conflict, it is possible that to resolve it, one or more insurance company separate accounts or qualified plans might be compelled to withdraw its investment in the Fund. While this might resolve the conflict, it also might force the Fund to sell securities at disadvantageous prices.

The Fund may also fair value securities that trade in a foreign market if significant events that appear likely to affect the value of those securities occur between the time the foreign market closes and the time as of which the Fund’s share price is calculated. Significant events may include (1) corporate actions or announcements that affect a single issuer, (2) governmental actions that affect securities in one sector, country or region, (3) natural disasters or armed conflicts that affect a country or region, or (4) significant domestic or foreign market fluctuations.

For certain foreign assets, after the relevant foreign markets have closed, a third-party vendor supplies evaluated, systematic fair value pricing based upon analysis of historical correlation of multiple factors. In the case of both foreign equity and foreign income securities, in the absence of precise information about the market values of these foreign securities as of the time as of which a Fund’s share price is calculated, the Board has determined on the basis of available data that prices adjusted or evaluated in this way are likely to be closer to the prices a Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Please see the Funds’ Statement of Additional Information for additional detail about the Funds’ fair valuation practices.

The effect of using fair value pricing is that a portfolio security will be priced based on the subjective judgment of the Manager, operating under procedures approved by the Board of Trustees, instead of being priced using valuations from an independent pricing service. Fair value pricing can help to protect the Fund by reducing arbitrage opportunities available to short-term traders, but there is no assurance that fair value pricing will completely prevent dilution of the Fund’s net asset value by such traders.

Fund Structure

While the Manager may serve as the adviser or sub-adviser of other mutual funds that have similar names, goals, and strategies as the Fund, there may be certain differences between the Fund and these other mutual funds in matters such as size, cash flow patterns and tax matters, among others. As a result, there could also be differences in performance.

is represented by any four investments. Section 817(h) and those regulations also provide, as a safe harbor, that a Separate Account will be treated as being adequately diversified if the diversification requirements under Subchapter M are satisfied and no more than 55% of the value of its total assets is represented by cash and cash items, government securities, and securities of other RICs. For purposes of those regulations, all securities of the same issuer are treated as a single investment, but each U.S. government agency or instrumentality is treated as a separate issuer. It is possible that complying with these requirements may at times call for decisions that could reduce investment performance.

The foregoing is only a summary of some of the important federal income tax considerations generally affecting the Fund and you. Please refer to the Statement of Additional Information for more information about the taxation of the Fund.
