NEUBERGER BERMAN CORE BOND FUND

SUMMARY PROSPECTUS

Class R6 Shares (NRCRX)

*Before you invest, you may want to review the Fund's prospectus, which contains more information about the Fund and its risks. <br> You can find the Fund's prospectus, reports to shareholders, and other information about the Fund (including the Fund's SAI) online at http://www.nb.com/fixedincomefunds/r6. You can also get this information at no cost by calling 800-366-6264 or by sending an e-mail request to fundinfo@nb.com. You can also get this information from your financial intermediary or any financial intermediary authorized to sell the Fund's shares. The Fund's prospectus and SAI, each dated February 28, 2023 (as each may be amended or supplemented), are incorporated herein by reference.*

**GOAL**

The Fund seeks to maximize total return consistent with capital preservation.

**FEES AND EXPENSES**

These tables describe the fees and expenses that you may pay if you buy, hold or sell shares of the Fund. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the table and example below.

<sup>1</sup> Neuberger Berman Investment Advisers LLC ("Manager") has contractually undertaken to waive and/or reimburse certain fees and expenses of Class R6 so that the total annual operating expenses (excluding interest, brokerage commissions, acquired fund fees and expenses, taxes including any expenses relating to tax reclaims, dividend and interest expenses relating to short sales, and extraordinary expenses, if any) ("annual operating expenses") are limited to 0.28% of average net assets. This undertaking lasts until 10/31/2026 and may not be terminated during its term without the consent of the Board of Trustees. The Fund has agreed that Class R6 will repay the Manager for fees and expenses waived or reimbursed for that class provided that repayment does not cause annual operating expenses to exceed 0.28% of its average net assets. Any such repayment must be made within three years after the year in which the Manager incurred the expense.

**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. 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 164% of the average value of its portfolio. During the most recent fiscal year, the Fund's portfolio turnover rate including to-be-announced ("TBA") roll transactions was 226%.

**PRINCIPAL INVESTMENT STRATEGIES**

To pursue its goal, the Fund normally invests in a diversified mix of debt securities, which primarily include government bonds, corporate bonds, mortgage-backed securities and asset-backed securities.

The Fund may invest in a broad array of securities, including: securities issued or guaranteed as to principal or interest by the U.S. government or any of its agencies or instrumentalities; municipal securities; foreign securities, including emerging markets; securities issued by supranational entities (e.g., World Bank, IMF); corporate bonds; mortgage-backed and asset-backed securities; inflation-linked debt securities; and commercial paper. Securities in which the Fund may invest may be issued by domestic and foreign governments, corporate entities and trusts and may be structured as fixed rate debt, floating rate debt, and debt that may not pay interest from the time of issuance. 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 may enter into a TBA agreement and "roll over" such agreement prior to the settlement

| **NEUBERGER BERMAN CORE BOND FUND** | February 28, 2023 |

---

date by selling the obligation to purchase the securities set forth in the agreement and entering into a new TBA agreement for future delivery of pools of mortgage-backed securities.

The debt securities in which the Fund invests primarily are investment grade. The Fund considers debt securities to be investment grade if, at the time of investment, they are rated within 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 also invest in derivative instruments as a means of hedging risk and/or for investment or efficient portfolio management purposes, which may include altering the Fund's exposure to currencies, interest rates, inflation, sectors and individual issuers. These derivative instruments may include futures, forward foreign currency contracts, and swaps, such as total return swaps, credit default swaps and interest rate swaps.

The Fund normally will not invest more than 15% of its total assets in non-U.S. dollar denominated securities and, through hedging strategies, will attempt to limit its exposure to currencies other than the U.S. dollar to 5% of its total assets.

Additionally, the Fund may invest in preferred securities. 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.

The Fund normally seeks to maintain its target average duration within one year of the average duration of the bonds in the Bloomberg U.S. Aggregate Bond Index, and, depending on market conditions, at times, the Fund may generally seek to maintain its target average duration within a maximum of two years of the average duration of the bonds in the Bloomberg U.S. Aggregate Bond Index.

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 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.

**Investment Philosophy and Process**

The Portfolio Management Team's investment philosophy is rooted in the belief that positive results can be achieved through a consistently applied, risk-managed approach to portfolio management that leverages the strengths of its proprietary fundamental research capabilities, decision-making frameworks, and quantitative risk management tools. The Portfolio Management Team employs an integrated investment process in managing the Fund.

■ **Portfolio Strategy:** The Portfolio Management Team establishes the investment profile for the Fund,
 which it monitors on an ongoing basis, including exposures to sectors (such as government,
 structured debt, credit, etc.) and duration/yield curve positioning, utilizing internally
 generated data that are produced by specialty sector investment teams in conjunction with
 asset allocation tools.

■ **Strategy Implementation:** Once the Portfolio Management Team establishes the investment profile
 for the Fund, the specialty sector investment teams and the Portfolio Management Team determine
 industry/sub-sector weightings and make securities selections within the types of securities
 that the Fund can purchase, such as investment grade securities and non-U.S. dollar denominated
 securities.

When assessing the value of a particular security, the teams utilize internally generated research and proprietary quantitatively driven tools and frameworks (including an analysis of cash flows, ability to pay principal and interest, balance sheet composition, and market positioning) to a) establish an internal outlook, b) evaluate the market's outlook as it is reflected in asset prices, and c) contrast the two. As part of their fundamental investment analysis, the Portfolio Managers consider Environmental, Social and Governance (ESG) factors they believe are financially material to individual investments, where applicable, as described below. While this analysis is inherently subjective and may be informed by internally generated and third-party metrics, data and other information, the Portfolio Managers believe that the consideration of financially material ESG factors, alongside traditional financial metrics, may improve credit analysis, security selection, relative value analysis and enhance the Fund's overall investment process. The specific ESG factors considered and scope and application of integration may vary depending on the specific investment and/or investment type. The consideration of ESG factors does not apply to certain instruments, such as certain derivative instruments, other registered investment companies, cash and cash equivalents. The consideration of ESG factors as part of the investment process does not mean that the Fund pursues a specific "impact" or "sustainable" investment strategy.

The teams will generally purchase securities if their internal outlook suggests a security is undervalued by the market and sell securities if their internal outlook suggests a security is overvalued by the market. The goal is to identify and evaluate investment opportunities that others may have missed.

**PRINCIPAL INVESTMENT RISKS**

Most of the Fund's performance depends on what happens in the market for 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.

**Commercial Paper Risk.** Commercial paper is a short-term debt security issued by a corporation, bank, municipality, or other issuer. Issuers generally do not register their commercial paper with the SEC. While some unregistered commercial paper normally is deemed illiquid, the Manager may in certain cases determine that such paper is liquid. In some cases, the ratings of commercial paper issuers have been downgraded abruptly, leaving holders with little opportunity to avoid losses.

**Credit Risk.** Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. Changes in the actual or perceived creditworthiness of an issuer or a downgrade or default affecting any of the Fund's securities could affect the Fund's performance by affecting the credit quality or value of the Fund's securities. Generally, the longer the maturity and the lower the credit quality of a security, the more sensitive it is to credit risk.

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

**Derivatives Risk.** Use of derivatives is a highly specialized activity that can involve investment techniques and risks different from, and in some respects greater than, those associated with investing in more traditional investments, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, and the Fund could lose more than the amount it invests; some derivatives can have the potential for unlimited losses. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce

---

exposure to other risks when that might have been beneficial. Derivatives involve counterparty risk, which is the risk that the other party to the derivative will fail to make required payments or otherwise comply with the terms of the derivative. That risk is generally thought to be greater with over-the-counter (OTC) derivatives than with derivatives that are exchange traded or centrally cleared. When the Fund uses derivatives, it will likely be required to provide margin or collateral; these practices are intended to satisfy contractual undertakings and regulatory requirements and will not prevent the Fund from incurring losses on derivatives. The need to provide margin or collateral could limit the Fund's ability to pursue other opportunities as they arise. Ongoing changes to regulation of the derivatives markets and actual and potential changes in the regulation of funds using derivative instruments could limit the Fund's ability to pursue its investment strategies. New regulation of derivatives may make them more costly, or may otherwise adversely affect their liquidity, value or performance.

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

**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.); imposition of economic sanctions against a particular country or countries, organizations, companies, entities and/or individuals; significant government involvement in an economy and/or market structure; fluctuations in foreign currencies or currency redenomination; potential for default on sovereign debt; nationalization or expropriation of assets; settlement, custodial or other operational risks; higher transaction costs; confiscatory withholding or other taxes; and less stringent auditing and accounting, corporate disclosure, governance, and legal standards. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

Securities of issuers traded on foreign exchanges may be suspended, either by the issuers themselves, by an exchange, or by governmental authorities. The likelihood of such suspensions may be higher for securities of issuers in emerging or less-developed

---

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

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

**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 measure 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 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. In periods of deflation, the Fund may have no income at all from such investments.

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.

**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.

**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") are generally not backed by the creditworthiness or taxing authority of the issuing governmental entity; rather, a particular business or facility may be the only source of revenue supporting payment of interest and principal, and declines in general business activity could affect the economic viability of that business or facility.

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 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.

**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.

**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.** Both U.S. and international markets have experienced significant volatility in recent months and years. As a result of such volatility, investment returns may fluctuate significantly. National economies are substantially interconnected, as are global financial markets, which creates the possibility that conditions in one country or region might

| **NEUBERGER BERMAN CORE BOND FUND** | February 28, 2023 |

---

adversely impact issuers in a different country or region. However, the interconnectedness of economies and/or markets may be diminishing, which may impact such economies and markets in ways that cannot be foreseen at this time.

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

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

Regulators in the U.S. have proposed a number of changes to regulations involving the markets and issuers, some of which would apply to the Fund. While it is not currently known whether any of these regulations will be adopted, due to the current scope of regulations being proposed, any changes to regulation could limit the Fund's ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, which, may in turn, impact performance.

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

The impact of the COVID-19 pandemic has negatively affected and could continue to affect the economies of many nations, individual companies and the global securities and commodities markets, including their liquidity, in ways that cannot necessarily be foreseen at the present time. Epidemics and/or pandemics, such as the coronavirus, have and may further result in, among other things, closing borders, extended quarantines and stay-at-home orders, order cancellations, disruptions to supply chains and customer activity, widespread business closures and layoffs, as well as general concern and uncertainty.

High public debt in the U.S. and other countries creates ongoing systemic and market risks and policymaking uncertainty. There is no assurance that the U.S. Congress will act to raise the nation's debt ceiling; a failure to do so could cause market turmoil and substantial investment risks that cannot now be fully predicted. Unexpected political, regulatory and diplomatic events within the U.S. and abroad may affect investor and consumer confidence and may adversely impact financial markets and the broader economy.

There is widespread concern about the potential effects of global climate change on property and security values. Certain issuers, industries and regions may be adversely affected by the impact of climate change in ways that cannot be foreseen. The impact of legislation, regulation and international accords related to climate change may negatively impact certain issuers and/or industries.

*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 and federal legislation has been enacted to ease the transition from LIBOR, but there is no assurance whether such legislation 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 and Supranational Entities 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.

The Fund may also invest in obligations issued or guaranteed by supranational entities, such as the World Bank. Supranational entities have no taxing authority and are dependent on their members for payments of interest and principal. If one or more members of a supranational entity fails to make necessary contributions, such entity may be unable to pay interest or repay principal on its debt securities. Political changes in principal donor nations may unexpectedly disrupt the finances of supranational entities.

**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 and any gain in the security's 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 an investment, the Fund may be required to value such investments using more subjective methods, known as fair value methodologies. Using fair value methodologies to price investments may result in a value that is different from an investment's most recent price and from the prices used by other funds to calculate their NAVs. The Fund uses pricing services to provide values for certain securities and there is no assurance that the Fund will be able to sell an investment at the price established by such pricing services. The Fund's ability to value its investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

**PERFORMANCE**

The following bar chart and table provide an indication of the risks of investing in the Fund. The bar chart shows how the Fund's performance has varied from year to year. The table below the bar chart shows what the returns would equal if you averaged out actual performance over various lengths of time and compares the returns with the returns of a broad-based market index. The index, which is described in "Descriptions of Indices" in the prospectus, has characteristics relevant to the Fund's investment strategy.

The performance prior to January 18, 2019 is that of the Fund's Institutional Class, which is not offered through this prospectus. Class R6 would have substantially similar performance to Institutional Class because the classes are invested in the same portfolio of securities. Because Institutional Class has higher expenses than Class R6, its performance typically would have been lower than that of Class R6. Returns would have been lower 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 800-877-9700 for updated performance information.
