GOAL

The Fund seeks high current income exempt from federal income tax.

Fees and Expenses

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. Under the Fund’s policies, you may qualify for initial sales charge discounts if you and your family invest, or agree to invest in the future, at least $50,000 in Neuberger Berman funds. Certain financial intermediaries have sales charges and/or policies and procedures regarding sales charge waivers applicable to their customers that differ from those described below. More information about these and other discounts is available from your financial intermediary, in “Sales Charge Reductions and Waivers” on page 155 in the Fund’s prospectus, and in Appendix A to the Fund’s prospectus. Although the Fund does not impose any sales charge on Institutional Class shares, you may pay a commission to your broker on your purchases and sales of those shares, which is not reflected in this table.

Expense Example

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

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual operating expenses or in the example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 112% of the average value of its portfolio.

Principal Investment Strategies

To pursue its goal, the Fund normally invests primarily in high-yielding municipal securities, which may include securities of any credit quality that the Portfolio Managers believe have the potential for relatively high yield. The Fund normally invests at least 80% of its net assets in securities of municipal issuers that provide interest income that is exempt from federal income tax and other investments that provide investment exposure to such securities; however, the Fund may invest without limit in municipal securities the interest on which may be an item of tax preference for purposes of the federal alternative minimum tax (“Tax Preference Item”). The Fund’s dividends are generally exempt from federal income tax, although shareholders may have to pay an alternative minimum tax on income deemed to be a Tax Preference Item. A portion of the dividends you receive may also be exempt from state and local income taxes, depending on where you live.

Municipal securities include securities issued by U.S. states, any of their political subdivisions, agencies, or instrumentalities, or by U.S. territories and possessions, such as Guam, the U.S. Virgin Islands, and Puerto Rico, and their political subdivisions and public corporations.

The Fund may invest in debt securities of any maturity or duration and does not have a target maturity or duration. The Fund may invest in debt securities across the credit spectrum, including investment grade securities, below investment grade securities (commonly known as “junk bonds”), and unrated securities, and has no limit on the percentage of its assets that it may invest in securities of a particular credit quality. The Fund considers debt securities to be below investment grade if, at the time of investment, they are rated below the four highest categories by at least one independent credit rating agency or, if unrated, are determined by the Portfolio Managers to be of comparable quality. The Fund may invest in or continue to hold securities that the Portfolio Managers believe have ratings or other factors that imply an imminent risk of default or that are in default or have defaulted with respect to the payment of interest or repayment of principal, depending on the Portfolio Managers’ evaluation of the investment opportunity.

The Fund seeks to reduce its exposure to credit risk by diversifying its assets among many municipal issuers and among the different types and maturities of municipal securities available. The Portfolio Managers monitor national trends in the municipal securities market, as well as a range of economic, financial and political factors. As part of the investment process, the Portfolio Managers analyze individual issues and look for securities that they believe offer compelling risk-adjusted return potential (based on some or all of the following, among other things, an analysis of cash flows, ability to pay principal and interest, balance sheet composition, market positioning and the team’s assessment of environmental, social and governance (ESG) considerations, with a secondary emphasis on duration control (i.e., monitoring and managing interest rate risk) and yield curve positioning (i.e., seeking attractive maturities on the yield curve). The Fund may sell securities if the Portfolio Managers find an opportunity they believe is more compelling or if the Portfolio Managers’ outlook on the investment or the market changes.

Additionally, the Fund may invest in tender option bonds (which include inverse floaters created as part of tender option bond transactions), zero coupon municipal securities, inflation-linked debt securities, restricted securities, mortgage-related securities (e.g., single and multi-family housing bonds), and fixed, variable, and floating rate municipal securities. The Fund may also invest in other investment companies, including funds in the Neuberger Berman fund family and unaffiliated investment companies, including exchange-traded funds (“ETFs”, and collectively, “Underlying Funds”), if the investment companies invest principally in the types of investments in which the Fund may invest directly.

The Fund may also invest in derivative instruments as a means of hedging or for investment purposes, which may include altering the Fund’s exposure to interest rates, sectors and individual issuers and increasing the Fund’s investment exposure beyond that which it could achieve by investing directly in more conventional securities. These derivative instruments may include options, futures (including Treasury futures), inverse floating rate securities and swaps, such as total return swaps, credit default swaps and interest rate swaps. The Fund may also engage in when-issued and forward-settling transactions, which involve buying or selling securities with payment and delivery taking place at a future date. In an effort to achieve its goal, the Fund may engage in active and frequent trading.

The Fund normally invests at least 80% of its net assets, plus the amount of any borrowings for investment purposes, in securities of municipal issuers that provide interest income that is exempt from federal income tax and other investments that provide investment exposure to such securities; however, the Fund may invest without limit in municipal securities the interest on which

may be a Tax Preference Item. The Fund may not change this fundamental policy without shareholder approval. This test is applied at the time the Fund invests; later percentage changes caused by a change in Fund assets or market values will not require the Fund to dispose of a holding.

The Fund is not an appropriate investment for tax-advantaged retirement accounts, such as 401(k) plan accounts or individual retirement accounts, or for investors subject to the federal alternative minimum tax, and may not be beneficial for investors in low tax brackets.

PRINCIPAL INVESTMENT RISKS

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

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

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. In addition, the Fund may also realize a taxable gain or loss on such securities.

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.

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. 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 potential changes in the

regulation of funds using derivative instruments could limit the Fund’s ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance.

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

Futures. Futures contracts are subject to the risk that an exchange may impose price fluctuation limits, which may make it difficult or impossible for a fund to close out a position when desired. To the extent a Fund enters into futures contracts requiring physical delivery (e.g., certain commodities contracts), the inability of the Fund to take or make physical delivery can negatively impact performance.

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

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.

Distressed Securities Risk. Distressed securities may present a substantial risk of default, including the loss of the entire investment, or may be in default. The Fund may not receive interest payments on the distressed securities and may incur costs to protect its investment. The prices of such securities may be subject to periods of abrupt and erratic market movements and above-average price volatility and it may be difficult to value such securities. In certain periods, there may be little or no liquidity in the markets for distressed securities meaning that the Fund may be unable to exit its position.

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

Inflation-Linked Debt Securities Risk. Inflation-linked debt securities are structured to provide protection against inflation. The value of the principal or the interest income paid on an inflation-linked debt security is adjusted to track changes in an official inflation measure. There can be no assurance that the inflation index used will accurately measure the real rate of inflation in the prices of goods and services. The value of inflation-linked debt securities is expected to change in response to changes in real interest rates. Real interest rates are tied to the relationship between nominal interest rates and the rate of inflation. In periods of deflation, the Fund may have no income at all from such investments. In general, the price of an inflation-linked debt security falls when real interest rates rise, and rises when real interest rates fall. Interest payments on inflation-linked debt securities will vary as the principal and/or interest is adjusted for inflation and can be unpredictable. The principal value of an investment in the Fund is not protected or otherwise guaranteed by virtue of the Fund’s investments in inflation-linked debt securities.

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.

Inverse Floater Risk. An inverse floater earns interest at rates that vary inversely to changes in short-term interest rates. An inverse floater produces less income (and may produce no income) and may decline in value when market rates rise. An investment in an inverse floater may involve greater risk than an investment in a fixed rate security. Inverse floaters generally will underperform the market for fixed rate securities in a rising interest rate environment. An inverse floater typically involves leverage, which can magnify the Fund’s losses.

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.

Municipal Securities Risk. The municipal securities market could be significantly affected by adverse political and legislative changes, as well as uncertainties related to taxation or the rights of municipal security holders. Changes in the financial health of a municipality or other issuer, or an insurer of municipal securities, may make it difficult for it to pay interest and principal when due and may affect the overall municipal securities market. To the extent that the Fund invests a significant portion of its assets in the municipal securities of a particular state or U.S. territory or possession, there is greater risk that political, regulatory, economic or other developments within that jurisdiction may have a significant impact on the Fund’s investment performance. Declines in real estate prices and general business activity may reduce the tax revenues of state and local governments. Municipal issuers have on occasion defaulted on obligations, been downgraded, or commenced insolvency proceedings.

Because many municipal securities are issued to finance similar types of projects, especially those related to education, health care, housing, transportation, and utilities, conditions in those sectors can affect the overall municipal securities market. Interest on municipal securities paid out of current or anticipated revenues from a specific project or specific asset (so-called “private activity bonds”) may be adversely impacted by declines in revenue from the project or asset. Declines in general business activity could affect the economic viability of facilities that are the sole source of revenue to support private activity bonds. To the extent that the Fund earns interest income on private activity bonds, a part of its dividends will be a Tax Preference Item.

Municipal bonds may be bought or sold at a market discount (i.e., a price less than the bond’s principal amount or, in the case of a bond issued with original issue discount (“OID”), a price less than the amount of the issue price plus accrued OID). If the market discount is more than a de minimis amount, and if the bond has a maturity date of more than one year from the date it was issued, then any market discount that accrues annually, or any gains earned on the disposition of the bond, generally will be subject to federal income taxation as ordinary (taxable) income rather than as capital gains. Some municipal securities, including those in the high yield market, may include transfer restrictions similar to restricted securities (e.g., may only be transferred to qualified institutional buyers and purchasers meeting other qualification requirements set by the issuer). As such, it may be difficult to sell municipal securities 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.

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

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

The Fund is also exposed to the affiliated Underlying Funds’ expenses, which could result in the duplication of certain fees, including the administration fees that are paid to Neuberger Berman Investment Advisers LLC (“NBIA”). NBIA is the investment manager for both the Fund and the affiliated Underlying Funds and may be deemed to have a conflict of interest in determining the allocation of the Fund to the affiliated Underlying Funds. This conflict of interest is reduced, however, because the Manager has undertaken to waive a portion of the Fund's advisory fee equal to the advisory fee it receives from affiliated Underlying Funds on the Fund’s assets invested in those affiliated Underlying Funds.

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.

Recent Market Conditions. National economies are increasingly interconnected, as are global financial markets, which increases the possibilities 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. Equity markets in the U.S. and China have been very sensitive to the outlook for resolving the U.S.-China “trade war,” a trend that may continue in the future.

Many municipal issuers may suffer substantial declines in tax revenue because of the business and economic disruptions associated with the COVID-19 pandemic. Because this situation is relatively new and ongoing, it may be difficult to evaluate the effect on any single issuer. Some municipal issuers may be prohibited by law from borrowing, and those that can borrow may face higher interest rates. This situation may result in disruption of municipal programs and services.

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, and central banks have reduced rates further in an effort to combat the economic effects of the COVID-19 pandemic. Because there is little precedent for this situation, it is difficult to predict the impact on various markets of a significant rate increase or other significant policy changes. 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.

Funds and their advisers, as well as many of the companies in which they invest, are subject to regulation by the federal government. Over the past several years, the U.S. has moved away from tighter industry regulation, a trend that may change going forward. 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. Economists and others have expressed increasing concern about the potential effects of global climate change on property and security values. A rise in sea levels, an increase in powerful windstorms and/or a climate-driven increase in flooding could cause coastal properties to lose value or become unmarketable altogether. Economists warn that, unlike previous declines in the real estate market, properties in affected coastal zones may not ever recover their value. Large wildfires driven by high winds and prolonged drought may devastate businesses and entire communities and may be very costly to any business found to be responsible for the fire. The new U.S. administration appears concerned about the climate change problem and may focus 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 heavy redemptions that could cause the Fund to sell assets at inopportune times 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. In addition, redemption risk is heightened during periods of declining or illiquid markets. Heavy redemptions could hurt the Fund’s performance. Regulators have expressed concern that 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, and that 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.

Tender Option Bonds and Related Securities Risk. The Fund's use of tender option bonds may reduce the Fund's return and/or increase volatility. Tender option bonds are created when municipal bonds are deposited into a trust or other special purpose vehicle, which issues two classes of certificates with varying economic interests. Holders of floating rate certificates receive tax-exempt interest based on short-term rates and may tender the certificates to the trust at face value. Holders of residual income certificates (“inverse floaters”) receive tax-exempt interest at a rate based on the difference between the interest rate earned on the underlying bonds and the interest paid to floating rate certificate holders, and bear the risk that the underlying bonds decline in value. Investments in tender option bonds expose the Fund to counterparty risk and leverage risk. An investment in tender option bonds typically will involve greater risk than an investment in a municipal fixed rate security, including greater risk of loss of principal. Certain tender option bonds may be illiquid. A trust may be terminated if, for example, the issuer of the underlying bond defaults on interest payments or the credit rating assigned to the issuer of the underlying bond is downgraded.

Tobacco Related Bonds Risk. In 1998, the largest U.S. tobacco manufacturers reached an agreement, known as the Master Settlement Agreement (“MSA”), to settle claims against them by 46 states and six other U.S. jurisdictions. The tobacco manufacturers agreed to make annual payments to the government entities in exchange for the release of all litigation claims. A number of the states have sold bonds that are backed by those future payments. The payments are based on factors, including, but not limited to, annual domestic cigarette shipments, cigarette consumption, inflation and the financial capability of participating tobacco companies. Payments could be reduced if consumption decreases, if market share is lost to non-MSA manufacturers, or if there is a negative outcome in litigation regarding the MSA, including challenges by participating tobacco manufacturers regarding the amount of annual payments owed under the MSA.

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 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.

Zero Coupon Bond Risk. Zero coupon bonds do not make periodic interest payments. Instead, they are sold at a discount from their face value and can be redeemed at face value when they mature. The market value of zero coupon bonds may respond to changes in interest rates to a greater degree (i.e., they are generally more volatile) than other fixed income securities with similar maturities and credit quality.

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. 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.

PERFORMANCE

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

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

Past performance (before and after taxes) is not a prediction of future results. Visit www.nb.com or call 800-366-6264 for updated performance information.

After-tax returns are shown for Institutional Class shares only and after-tax returns for other classes may vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown.

[1] For Class A shares, a contingent deferred sales charge (“CDSC”) of 1.00% applies on certain redemptions made within 18 months following purchases of $1 million or more made without an initial sales charge. For Class C shares, the CDSC is eliminated one year after purchase.

[1] Neuberger Berman Investment Advisers LLC (“Manager”) has contractually undertaken to waive and/or reimburse certain fees and expenses of Class A, Class C and Institutional Class so that the total annual operating expenses (excluding interest, taxes, brokerage commissions, acquired fund fees and expenses, dividend and interest expenses relating to short sales, and extraordinary expenses, if any) (“annual operating expenses”) of each class are limited to 0.87%, 1.62% and 0.50% of average net assets, respectively. Each of these undertakings lasts until 10/31/2024 and may not be terminated during its term without the consent of the Board of Trustees. The Fund has agreed that each of Class A, Class C and Institutional Class will repay the Manager for fees and expenses waived or reimbursed for the class provided that repayment does not cause annual operating expenses to exceed 0.87%, 1.62% and 0.50% of the class' average net assets, respectively. Any such repayment must be made within three years after the year in which the Manager incurred the expense.
