Descriptions of Certain Practices and Security Types

Convertible Securities. Convertible securities are bonds, debentures, notes, preferred stocks and other securities that pay interest or dividends and are convertible into or exchangeable for common stocks. Convertible securities generally have some features of common stocks and some features of debt securities. In general, a convertible security performs more like a stock when the underlying stock’s price is high relative to the conversion price (because it is assumed that it will be converted into the stock) and performs more like a debt security when the underlying stock’s price is low relative to the conversion price (because it is assumed that it will mature without being converted). Convertible securities typically pay an income yield that is higher than the dividend yield of the issuer’s common stock, but lower than the yield of the issuer’s debt securities.

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

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

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

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

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

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

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

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

Inflation-Linked Debt Securities. Inflation-linked debt securities are debt securities whose principal value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of inflation-linked debt securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced.

Loans. Loans are a type of debt security that may be made in connection with, among other things, recapitalizations, acquisitions, leveraged buyouts, dividend issuances and refinancings. The loans in which a Fund typically invests are structured and administered by a third party that acts as agent for a group of lenders that make or hold interests in the loan. A Fund may acquire interests in such loans by taking an assignment of all or a portion of a direct interest in a loan previously held by another institution or by acquiring a participation in an interest in a loan that continues to be held by another institution.

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

Municipal Securities. Municipal securities include, among other types of instruments, general obligation bonds, revenue bonds, private activity bonds, anticipation notes and tax-exempt commercial paper. General obligation bonds are backed by the full taxing power of the issuing governmental entity. Revenue bonds are backed only by the income from a specific project, facility, or tax. Private activity bonds are issued by or on behalf of public authorities to finance various privately operated facilities, and are generally supported only by revenue from those facilities, if any. They are not backed by the credit of any governmental or public authority. Anticipation notes are issued by municipalities in expectation of future proceeds from the issuance of bonds or from taxes or other revenues and are payable from those bond proceeds, taxes, or revenues. Tax-exempt commercial paper is issued by municipalities to help finance short-term capital or operating requirements.

Additional Information about Principal Investment Risks

This section provides additional information about a Fund’s principal investment risks described in its Fund Summary section. The following risks are described in alphabetical order and not in order of any presumed importance or potential exposure.

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 or other less favorable characteristics. This may reduce the amount of the Fund’s distributions. In addition, the Fund may not benefit from any increase in value in the securities that might otherwise result from declining interest rates. The likelihood of a call also may impact the price of a security.

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

Commercial Paper Risk. Commercial paper is a short-term debt security issued by a corporation, bank, municipality, or other issuer, usually for purposes such as financing current operations. Issuers generally do not register their commercial paper with the SEC. A Fund may invest in commercial paper that cannot be resold to the public without an effective registration statement under the 1933 Act. Among other factors, the value of commercial paper may be affected by changes in interest rates and the credit rating and financial condition of the issuer. Commercial paper is subject to the risk that the issuer will be unable to issue sufficient new commercial paper to meet the repayment obligations under its outstanding commercial paper (commonly referred to as rollover risk). While some unregistered commercial paper 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. Commercial paper is generally unsecured, which increases its credit risk, and is usually issued at a discount from their value at maturity.

Convertible Securities Risk. The value of a convertible security, which is a form of hybrid security (i.e., a security with both debt and equity characteristics), typically increases or decreases with the price of the underlying common stock. In general, a convertible security is subject to the market risks of stocks, and its price may be as volatile as that of the underlying stock, when the underlying stock’s price is high relative to the conversion price, and a convertible security is subject to the market risks of debt securities, and is particularly sensitive to changes in interest rates, when the underlying stock’s price is low relative to the conversion price. The general market risks of debt securities that are common to convertible securities include, but are not limited to, interest rate risk and credit risk. Because their value can be influenced by many different factors, convertible securities generally have less potential for gain or loss than the underlying common stocks. Securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities that are convertible only at the option of the holder.

Many convertible securities have credit ratings that are below investment grade and are subject to the same risks as an investment in lower-rated debt securities. The credit rating of a company’s convertible securities is generally lower than that of its non-convertible debt securities. Convertible securities are normally considered “junior” securities — that is, the company usually must pay interest on its non-convertible debt securities before it can make payments on its convertible securities. If the issuer stops paying interest or principal, convertible securities may become worthless and the Fund could lose its entire investment. To the extent the Fund invests in convertible securities issued by small- or mid-cap companies, it will be subject to the risks of investing in such companies. The securities of small- and mid-cap companies may fluctuate more widely in price than the market as a whole. There may also be less trading in small- or mid-cap securities, which means that buy and sell transactions in those securities could have a larger impact on a security’s price than is the case with large-cap securities.

Credit Risk. Credit risk is the risk that issuers, guarantors, or insurers may fail, or become less able or unwilling, to pay interest and/or principal when due. Changes in the actual or perceived creditworthiness of an issuer, factors affecting an issuer directly (such as management changes, labor relations, collapse of key suppliers or customers, or material changes in overhead costs), factors affecting the industry in which a particular issuer operates (such as competition or technological advances) and changes in general social, economic or political conditions can increase the risk of default by an issuer, which may affect a security’s credit quality or value. 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. In addition, lower credit quality may lead to greater volatility in the price of a security and may negatively affect a security’s liquidity. Ratings represent a rating agency’s opinion regarding the quality of a security and are not a guarantee of quality, and do not protect against a decline in the value of a security. In addition, rating agencies may fail to make timely changes to credit ratings in response to subsequent events and a rating may become stale in that it fails to reflect changes in an issuer’s financial condition. The credit quality of a security or instrument can deteriorate suddenly and rapidly, which may negatively impact its liquidity and value. The securities in which the Fund invests may be subject to credit enhancement (for example, guarantees, letters of credit, or bond insurance). Entities providing credit or liquidity support also may be affected by credit risk. Credit enhancement is designed to help assure timely payment of the security; it does not protect the Fund against losses caused by declines in a security’s value due to changes in market conditions.

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

Derivatives Risk. Use of derivatives is a highly specialized activity that can involve investment techniques and risks different from, and in some respects greater than, those associated with investing in more traditional investments, such as stocks and bonds. Derivatives can be highly complex and highly volatile and may perform in unanticipated ways. Derivatives can create leverage, which can magnify the impact of a decline in the value of the reference instrument underlying the derivative, and the Fund could

lose more than the amount it invests. Derivatives can have the potential for unlimited losses, for example, where the Fund may be called upon to deliver a security it does not own. Derivatives may at times be highly illiquid, and the Fund may not be able to close out or sell a derivative at a particular time or at an anticipated price. Derivatives can be difficult to value and valuation may be more difficult in times of market turmoil. The value of a derivative instrument depends largely on (and is derived from) the value of the reference instrument underlying the derivative. There may be imperfect correlation between the behavior of a derivative and that of the reference instrument underlying the derivative, and the reference instrument may not perform as anticipated. An abrupt change in the price of a reference instrument could render a derivative worthless. Derivatives may involve risks different from, and possibly greater than, the risks associated with investing directly in the reference instrument. Suitable derivatives may not be available in all circumstances, and there can be no assurance that the Fund will use derivatives to reduce exposure to other risks when that might have been beneficial. Derivatives may involve fees, commissions, or other costs that may reduce the Fund’s gains or exacerbate losses from the derivatives. In addition, the Fund’s use of derivatives may have different tax consequences for the Fund than an investment in the reference instruments, and those differences may increase the amount and affect the timing of income recognition and character of taxable distributions payable to shareholders. Thus, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirements. Certain aspects of the regulatory treatment of derivative instruments, including federal income tax, are currently unclear and may be affected by changes in legislation, regulations, or other legally binding authority. In October 2020, the SEC adopted Rule 18f-4 under the 1940 Act which regulates the use of derivatives for certain funds registered under the Investment Company Act (“Rule 18f-4”). The Fund has adopted a Rule 18f-4 Policy which provides, among other things, that unless the Fund qualifies as a “limited derivatives user” as defined in Rule 18f-4, the Fund is subject to a comprehensive derivatives risk management program, to comply with certain value-at-risk based leverage limits, and to provide additional disclosure both publicly and to the SEC regarding its derivatives positions. If a Fund qualifies as a limited derivatives user, Rule 18f-4 requires the Fund to have policies and procedures to manage its aggregate derivatives risk.

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

When the Fund uses derivatives, it will likely be required to provide margin or collateral; 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. Derivatives that have margin requirements involve the risk that if the Fund has insufficient cash or eligible margin securities to meet daily variation margin requirements, it may have to sell securities or other instruments from its portfolio at a time when it may be disadvantageous to do so. The Fund normally will remain obligated to meet margin requirements until a derivatives position is closed.

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

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

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

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

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

offsetting transactions rather than taking or making delivery. To the extent a Fund enters into futures contracts requiring physical delivery (e.g., certain commodities contracts), the inability of the Fund to take or make physical delivery can negatively impact performance.

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

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

Foreign and Emerging Market Risk. Foreign securities, including those issued by foreign governments, involve risks in addition to those associated with comparable U.S. securities. Additional risks include exposure to less developed or less efficient trading markets; social, political, diplomatic, or economic instability; trade barriers and other protectionist trade policies (including those of the U.S.); 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. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities. In addition, key information about the issuer, the markets or the local government or economy may be unavailable, incomplete, or inaccurate. As a result, foreign securities may fluctuate more widely in price, and may also be less liquid, than comparable U.S. securities. World markets, or those in a particular region, may all react in similar fashion to important economic or political developments. In addition, securities issued by U.S. entities with substantial foreign operations may involve risks relating to political, economic, or regulatory conditions in foreign countries, as well as currency exchange rates. Regardless of where a company is organized or its stock is traded, its performance may be affected significantly by events in regions from which it derives its profits or in which it conducts significant operations.

Investing in emerging market countries involves risks in addition to and greater than those generally associated with investing in more developed foreign countries. The governments of emerging market countries may be more unstable and more likely to impose capital controls, nationalize a company or industry, place restrictions on foreign ownership and on withdrawing sale proceeds of securities from the country, intervene in the financial markets, and/or impose burdensome taxes that could adversely affect security prices. To the extent a foreign security is denominated in U.S. dollars, there is also the risk that a foreign government will not let U.S. dollar-denominated assets leave the country. In addition, the economies of emerging market countries may be dependent on relatively few industries that are more susceptible to local and global changes, and may suffer from extreme and volatile debt burdens or inflation rates. Emerging market countries may also have less developed legal and accounting systems, and their legal systems may deal with issuer bankruptcies and defaults differently than U.S. law would. Shareholder claims and legal remedies that are common in the United States may be difficult or impossible to pursue in many emerging market countries. In addition, due to jurisdictional limitations, matters of comity and various other factors, U.S. authorities may be limited in their ability to bring enforcement actions against non-U.S. companies and non-U.S. persons in certain emerging market countries. Most foreign and emerging market companies are not subject to the uniform accounting, auditing and financial reporting requirements applicable to issuers in the United States, which may impact the availability and quality of information about foreign and emerging market issuers. Securities markets in emerging market countries are also relatively small and have substantially lower trading volumes. Additionally, in times of market stress, regulatory authorities of different emerging market countries may apply varying techniques and degrees of intervention, which can have an effect on prices. Securities of issuers in emerging market countries may be more volatile and less liquid than securities of issuers in foreign countries with more developed economies or markets and the situation may require that the Fund fair value its holdings in those countries.

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

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

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

High Portfolio Turnover Risk. 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 Fund’s investments in inflation-linked debt securities may lose value in the event that the actual rate of inflation is different than the rate of the inflation measure. In addition, any inflation measure used could be discontinued, substituted or changed in a manner that could adversely impact such securities.

Repayment of the original principal upon maturity (as adjusted upward for inflation, as needed) is guaranteed in the case of U.S. Treasury inflation-indexed debt securities. For inflation-linked debt securities that do not provide a similar guarantee, the adjusted principal value of the securities repaid at maturity may be less than the original principal value. 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, (i.e., when nominal interest rates increase at a faster rate than inflation), and rises when real interest rates fall (i.e., when inflation rises at a faster rate than nominal interest rates). 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.

Any increase in the principal value of an inflation-linked debt security is taxable in the year the increase occurs, even though the security’s holders do not receive cash representing the increase until the security matures. Thus, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirements.

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

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, and produces more income and may increase in value when market rates fall. Whereas ordinary fixed income securities suffer a decline in value when market rates rise, this phenomenon is exacerbated in the case of inverse floaters, because when market rates rise, the rate paid by the inverse floater declines, producing greater price and income volatility than a conventional fixed-rate bond with comparable credit quality and maturity. An investment in an inverse floater involves the risk of loss of principal and 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 may involve leverage, which may make the Fund’s returns more volatile,

increase interest rate risk and can magnify the Fund’s losses. Accordingly, the holder of an inverse floater could lose more than its principal investment.

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

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

Liquidity Risk. From time to time, the trading market for a particular investment or type of investment in which the Fund invests is or may become less liquid or even illiquid. Illiquid investments frequently can be more difficult to purchase or sell at an advantageous price or time. An illiquid investment means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment. Judgment plays a greater role in pricing these investments than it does in pricing investments having more active markets, and there is a greater risk that the investments may not be sold for the price at which the Fund is carrying them. The Fund may receive illiquid securities as a result of its investment in securities involved in restructurings. Certain investments that were liquid when the Fund purchased them may become illiquid, sometimes abruptly, particularly during periods of increased market volatility, adverse investor perception, economic uncertainty or changes in interest rates. 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, which can be extensive. An inability to sell a portfolio position can adversely affect the Fund’s value or prevent the Fund from being able to take advantage of other investment opportunities. Market prices for such securities or other investments may be volatile. Market participants attempting to sell the same or a similar investment at the same time as the Fund could decrease the liquidity of such investments, especially during times of market volatility. During periods of substantial market volatility, an investment or even an entire market segment may become illiquid, sometimes abruptly, which can adversely affect the Fund’s ability to limit losses.

Unexpected episodes of illiquidity, including due to market or political factors, instrument or issuer-specific factors and/or unanticipated outflows or other factors, may limit the Fund’s ability to pay redemption proceeds within the allowable time period. To meet redemption requests during periods of illiquidity, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions.

Loan Interests Risk. Loan interests generally are subject to restrictions on transfer, and the Fund may be unable to sell its loan interests at a time when it may otherwise be desirable to do so or may be able to sell them promptly only at prices that are less than what the Fund regards as their fair market value. Accordingly, loan interests may at times be illiquid. Loan interests may be difficult to value and may have extended settlement periods (the settlement cycle for many bank loans exceeds 7 days). Extended settlement periods may result in cash not being immediately available to the Fund. As a result, during periods of unusually heavy redemptions, the Fund may have to sell other investments or borrow money to meet its obligations. A significant portion of floating rate loans may be “covenant lite” loans that may contain fewer or less restrictive constraints on the borrower and/or may contain other characteristics that would be favorable to the borrower, limiting the ability of lenders to take legal action to protect their interests in certain situations. Interests in loans made to finance highly leveraged companies or to finance corporate acquisitions or other transactions may be especially vulnerable to adverse changes in economic or market conditions.

Interests in secured loans have the benefit of collateral and, typically, of restrictive covenants limiting the ability of the borrower to further encumber its assets, although many covenants may be waived or modified with the consent of a certain percentage of the holders of the loans even if the Fund does not consent. There is a risk that the value of any collateral securing a loan in which the Fund has an interest may decline and that the collateral may not be sufficient to cover the amount owed on the loan. In most loan

agreements there is no formal requirement to pledge additional collateral. In the event the borrower defaults, the Fund’s access to the collateral may be limited or delayed by bankruptcy or other insolvency laws. Further, in the event of a default, second or lower lien secured loans, and unsecured loans, will generally be paid only if the value of the collateral exceeds the amount of the borrower’s obligations to the senior secured lenders, and the remaining collateral may not be sufficient to cover the full amount owed on the loan in which the Fund has an interest. In addition, if a secured loan is foreclosed, the Fund may bear the costs and liabilities associated with owning and disposing of the collateral. The collateral may be difficult to sell and the Fund would bear the risk that the collateral may decline in value while the Fund is holding it. Further, there is a risk that a court could take action with respect to a loan that is adverse to the holders of the loan and the Fund may need to retain legal counsel to enforce its rights in any resulting event of default, bankruptcy, or similar situation, which may increase the Fund’s operating expenses. Interests in loans expose the Fund to the credit risk of the underlying borrower and may expose the Fund to the credit risk of the lender.

The Fund may acquire a loan interest by direct investment as a lender, by obtaining an assignment of all or a portion of the interests in a particular loan that are held by an original lender or a prior assignee or by participation in a loan interest that is held by another party. As an assignee, the Fund normally will succeed to all rights and obligations of its assignor with respect to the portion of the loan that is being assigned. However, the rights and obligations acquired by the purchaser of a loan assignment may differ from, and be more limited than, those held by the original lenders or the assignor.

When the Fund’s loan interest is a participation, the Fund may have less control over the exercise of remedies than the party selling the participation interest, and the Fund normally would not have any direct rights against the borrower. As a participant, the Fund also would be subject to the risk that the lending bank or other party selling the participation interest would not remit the Fund’s pro rata share of loan payments to the Fund. It may be difficult for the Fund to obtain an accurate picture of a lending bank’s financial condition. It is possible that the Fund could be held liable, or may be called upon to fulfill other obligations, with respect to loans in which it receives an assignment in whole or in part, or in which it owns a participation. The potential for such liability is greater for an assignee than for a participant.

The liquidity of floating rate loans, including the volume and frequency of secondary market trading in such loans, may vary, sometimes significantly, over time and among individual floating rate loans and loans may be subject to wide bid/ask spreads. During periods of infrequent trading, valuing a floating rate loan can be more difficult; and buying and selling a floating rate loan at an acceptable price can be more difficult and delayed.

Courts have held in some situations that loan interests are not “securities,” and purchasers, such as the Fund, therefore may not have the benefit of the anti-fraud protections of the federal securities laws. Also, if Fund management receives material non-public information about the issuer (which is not uncommon in the loan market), the Fund may, as a result, be unable to sell the issuer’s securities.

Lower-Rated Debt Securities Risk. Lower-rated debt securities (commonly known as “junk bonds”) and unrated debt securities determined to be of comparable quality involve greater risks than investment grade debt securities. Such securities may fluctuate more widely in price and yield and may fall in price, sometimes abruptly, due to changes in interest rates, market activity, economic conditions, such as when economic conditions are deteriorating or are expected to deteriorate, or other factors. These securities may be less liquid and also may require a greater degree of judgment to establish a price, may be difficult to sell at the time and price the Fund desires, and may carry higher transaction costs. In particular, these securities may be issued by smaller companies or by highly indebted companies, which are generally less able than more financially stable companies to make scheduled payments of interest and principal. Lower-rated debt securities are considered by the major rating agencies to be predominantly speculative with respect to the issuer’s continuing ability to pay principal and interest and carry a greater risk that the issuer of such securities will default in the timely payment of principal and interest. Such securities are susceptible to such a default or decline in market value due to real or perceived adverse economic and business developments relating to the issuer, the industry in general, market interest rates and market liquidity. Such securities may be unsecured or have insufficient collateral and may be subordinated to other creditors, which increases the risk of loss on these securities. Issuers of securities that are in default or have defaulted may fail to resume principal or interest payments, in which case the Fund may lose its entire investment. Where it deems it appropriate and in the best interests of Fund shareholders, the Fund may incur additional expenses to seek recovery on a defaulted security and/or to pursue litigation to protect the Fund’s investment.

The credit rating of a security may not accurately reflect the actual credit risk associated with such a security. The creditworthiness of issuers of these securities may be more complex to analyze than that of issuers of investment grade debt securities, and the overreliance on credit ratings may present additional risks.

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

Market Volatility Risk. Markets may be volatile and values of individual securities and other investments, including those of a particular type, may decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments that may cause broad changes in market value, public perceptions concerning these developments, and adverse investor sentiment or publicity. Changes in the financial condition of a single issuer may impact a market as a whole. Changes in value may be temporary or may last for extended periods. If the Fund sells a portfolio position before it reaches its market peak, it may miss out on opportunities for better performance. Geopolitical risks, including terrorism, tensions or open conflict between nations, or political or economic dysfunction within some nations that are major players on the world stage or major producers of oil, may lead to overall instability in world economies and markets generally and have led, and may in the future lead, to increased market volatility and may have adverse long-term effects. Similarly, environmental and public health risks, such as natural disasters or epidemics, or widespread fear that such events may occur, may impact markets and economies adversely and cause market volatility in both the short- and long-term.

Mortgage- and Asset-Backed Securities Risk. The value of mortgage- and asset-backed securities, including collateralized mortgage instruments, will be influenced by the factors affecting the housing market or the assets underlying the securities. These securities differ from more traditional debt securities because the principal is paid back over the life of the security rather than at the security’s maturity; however, principal may be repaid early if a decline in interest rates causes many borrowers to refinance (known as prepayment risk), or repaid more slowly if a rise in rates causes refinancings to slow down (known as extension risk). Thus, they tend to be more sensitive to changes in interest rates than other types of debt securities and as a result, these securities may exhibit additional volatility during periods of interest rate turmoil. Asset-backed securities also may not have the benefit of any security interest in the related assets. Mortgage- and asset-backed securities may be “subordinated” to other interests in the same pool and a holder of those “subordinated” securities would receive payments only after any obligations to other more “senior” investors have been satisfied. In addition, investments in mortgage- and asset-backed securities may be subject to call risk, credit risk, valuation risk, and illiquid investment risk, sometimes to a higher degree than various other types of debt securities. These securities are also subject to the risk of default on the underlying mortgages or assets, particularly during periods of market downturn, and an unexpectedly high rate of defaults on the underlying assets will adversely affect the security’s value. Further, such securities may have credit support, the utility of which could be negatively affected by such conditions as well.

Municipal Securities Risk. The municipal securities market could be significantly affected by adverse political and legislative changes or litigation at the federal or state level, as well as uncertainties related to taxation or the rights of municipal security holders. Changes in the financial health of a municipality may hinder its ability to pay interest and principal. 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. The amount of public information available about municipal securities is generally less than that available about corporate securities.

In the case of insured municipal securities, insurance supports the commitment that interest payments will be made on time and the principal will be repaid at maturity. Insurance does not, however, protect the Fund or its shareholders against losses caused by declines in a municipal security’s market value. The Portfolio Managers generally look to the credit quality of the issuer of a municipal security to determine whether the security meets the Fund’s quality restrictions, even if the security is covered by insurance. However, a downgrade in the claims-paying ability of an insurer of a municipal security could have an adverse effect on the market value of the security.

Municipal issuers may be adversely affected by high labor costs and increasing unfunded pension liabilities, and by the phasing out of federal programs providing financial support. In addition, changes in the financial condition of one or more individual municipal issuers or insurers of municipal issuers can affect the overall municipal securities market. At times, the secondary market for municipal securities may not be liquid, which could limit the Fund’s ability to sell securities it is holding. 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. Financial difficulties of municipal issuers may continue or get worse. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state.

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.

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.

Operational and Cybersecurity Risk. The Fund and its service providers, and your ability to transact with the Fund, may be negatively impacted due to operational matters arising from, among other problems, human errors, systems and technology disruptions or failures, or cybersecurity incidents. Cybersecurity incidents may allow an unauthorized party to gain access to fund assets, customer data, or proprietary information, or cause the Fund or its service providers, as well as the securities trading venues and their service providers, to suffer data corruption or lose operational functionality. Cybersecurity incidents can result from deliberate attacks (e.g., malicious software coding, ransomware, or “hacking”) or unintentional events (e.g., inadvertent release of confidential information). A cybersecurity incident could, among other things, result in the loss or theft of customer data or funds, customers or employees being unable to access electronic systems (“denial of services”), loss or theft of proprietary information or corporate data, physical damage to a computer or network system, or remediation costs associated with system repairs. A cybersecurity incident may not permit the Fund and its service providers to access electronic systems to perform critical duties for the Fund, such as trading and calculating net asset value. Any cybersecurity incident could have a substantial adverse impact on the Fund and its shareholders.

The occurrence of any of these problems could result in a loss of information, regulatory scrutiny, reputational damage and other consequences, any of which could have a material adverse effect on the Fund or its shareholders. The Manager, through its monitoring and oversight of Fund service providers, endeavors to determine that service providers take appropriate precautions to avoid and mitigate risks that could lead to such problems. While the Manager has established business continuity plans and risk management systems seeking to address these problems, there are inherent limitations in such plans and systems, and it is not possible for the Manager or the other Fund service providers to identify all of the cybersecurity or other operational risks that may affect the Fund or to develop processes and controls to completely eliminate or mitigate their occurrence or effects. Most issuers in which the Fund invests are heavily dependent on computers for data storage and operations, and require ready access to the internet to conduct their business. Thus, cybersecurity incidents could also affect issuers of securities in which the Fund invests, leading to significant loss of value.

Preferred Securities Risk. Preferred securities, which are a form of hybrid security (i.e., a security with both debt and equity characteristics), may pay fixed or adjustable rates of return. Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities, however, unlike common stocks, participation in the growth of an issuer may be limited. Distributions on preferred securities are generally payable at the discretion of the issuer’s board of directors and after the company makes required payments to holders of its debt securities. For this reason, preferred securities are subject to greater credit, interest, and liquidation risk than debt securities, and the value of preferred securities will usually react more strongly than debt securities to actual or perceived changes in the company’s financial condition or prospects. Preferred securities of smaller companies may be more vulnerable to adverse developments than preferred securities of larger companies. Preferred securities may be less liquid than common stocks, and there is a risk an issuer of preferred securities may call or redeem prior to any stated maturity. Preferred securities may include provisions that permit the issuer, at its discretion, to defer or omit distributions for a stated period without any adverse consequences to the issuer. Preferred shareholders may have certain rights if distributions are not paid, but generally have no legal recourse against the issuer, may suffer a loss of value if distributions are not paid and may be required to report the deferred distribution on its tax returns, even though it may not have received any cash. Generally, preferred shareholders have no voting rights with respect to the issuer unless distributions to preferred shareholders have not been paid for a stated period, at which time the preferred shareholders may elect a number of directors to the issuer’s board. Generally, once all the distributions have been paid to preferred shareholders, the preferred shareholders no longer have voting rights.

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 (i.e., a prepayment). As a result of prepayment, the Fund may have to reinvest the proceeds in an investment offering a lower yield, may not benefit from any increase in value that might otherwise result from declining interest rates, and may lose any premium it paid to acquire the security. Prepayments could also create capital gains tax liability in some instances. Conversely, rising market interest rates generally result in slower payoffs or extension, which effectively increases the duration of certain debt securities, heightening interest rate risk and increasing the magnitude of any resulting price declines. If the Fund’s investments are locked in at a lower interest rate for a longer period of time, the Fund may be unable to capitalize on securities with higher interest rates or wider spreads.

Private Placements and Other Restricted Securities Risk. Private placements and other restricted securities, including securities for which Fund management has material non-public information, are securities that are subject to legal and/or contractual

restrictions on their sales. These securities may not be sold to the public unless certain conditions are met, which may include registration under the applicable securities laws. These securities may not be listed on an exchange and may have no active trading market. As a result of the absence of a public trading market, the prices of these securities may be more volatile and more difficult to determine than publicly traded securities and these securities may involve heightened risk as compared to investments in securities of publicly traded companies. Private placements and other restricted securities may be illiquid, and it frequently can be difficult to sell them at a time when it may otherwise be desirable to do so or the Fund may be able to sell them only at prices that are less than what the Fund regards as their fair market value. A security that was liquid at the time of purchase may subsequently become illiquid. In addition, transaction costs may be higher for private placements and other restricted securities. The Fund may have to bear the expense of registering such securities for sale and there may be substantial delays in effecting the registration. If, during such a delay, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed at the time it decided to seek registration of the securities. In addition, the Fund may get only limited information about the issuer of a private placement or other restricted security, so it may be less able to anticipate a loss. Also, if Fund management receives material non-public information about the issuer, the Fund may, as a result, be legally prohibited from selling the securities.

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

Although interest rates were unusually low in recent years in the U.S. and abroad, recently, the Federal Reserve and certain foreign central banks raised interest rates as part of their efforts to address rising inflation. In addition, ongoing inflation pressures could continue to cause an increase in interest rates and/or negatively impact companies. It is difficult to accurately predict the pace at which interest rates might increase or start decreasing, or the timing, frequency or magnitude of any such changes in interest rates, or when such changes might stop or reverse course. Additionally, various economic and political factors could cause the Federal Reserve or other foreign central banks to change their approach in the future and such actions may result in an economic slowdown both in the U.S. and abroad. Unexpected changes in interest rates could lead to significant market volatility or reduce liquidity in certain sectors of the market. Deteriorating economic fundamentals may, in turn, increase the risk of default or insolvency of particular issuers, negatively impact market value, cause credit spreads to widen, and reduce bank balance sheets. Any of these could cause an increase in market volatility, reduce liquidity across various markets or decrease confidence in the markets. Also, regulators have expressed concern that changes in interest rates may cause investors to sell fixed income securities faster than the market can absorb them, contributing to price volatility. Over the longer term, the interest rate increases may present a greater risk than has historically been the case due to the prior period of relatively low interest rates and the effect of government fiscal and monetary policy initiatives and potential market reaction to those initiatives, or their alteration or cessation. Historical patterns of correlation among asset classes may break down in unanticipated ways during times of high volatility, disrupting investment programs and potentially causing losses.

Some countries, including the U.S., have 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 trade negotiations between the U.S. and China, could affect the economies of many nations in ways that cannot necessarily be foreseen at the present time. In addition, if the U.S. dollar continues to be strong, it 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 and adopted a number of changes to regulations involving the markets and issuers, some of which implicate a Fund. The full effect of various newly adopted regulations is not currently known. Additionally, it is not currently known whether any of the proposed regulations will be adopted. However, due to the scope of regulations being proposed and adopted, certain of these changes to regulation could limit a Fund’s ability to pursue its investment strategies or make certain investments, may make it more costly for it to operate, or adversely impact its performance.

Tensions, war, or open conflict between nations, such as between Russia and Ukraine, in the Middle East, or in eastern Asia could affect the economies of many nations, including the United States. The duration of ongoing hostilities and any sanctions and related events cannot be predicted. Those events present material uncertainty and risk with respect to markets globally and the performance of a Fund and its investments or operations could be negatively impacted.

Certain illnesses spread rapidly and have the potential to significantly and adversely affect the global economy. The impact of epidemics and/or pandemics that may arise in the future could negatively 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 and could last for an extended period of time.

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.

China’s economy, which had been sustained through debt-financed spending on housing and infrastructure, appears to be experiencing a significant slowdown and growing at a lower rate than prior years. Due to the size of China’s economy, such a slowdown could impact a number of other countries.

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.

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

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

Redemption Risk. The Fund may experience periods of large or frequent redemptions that could cause the Fund to sell assets at inopportune times, which could have a negative impact on the Fund’s overall liquidity, or at a loss or depressed value. Redemption risk is greater to the extent that one or more investors or intermediaries control a large percentage of investments in the Fund, have short investment horizons, or have unpredictable cash flow needs. In addition, the risk is heightened if redemption requests are unusually large or frequent or occur during periods of declining or illiquid markets. Large redemptions could hurt the Fund’s performance, increase transaction costs and create adverse tax consequences.

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

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

Sector Risk. From time to time, based on market or economic conditions, the Fund may have significant positions in one or more sectors of the market. To the extent the Fund invests more heavily in one sector, industry, or sub-sector of the market, its performance will be especially sensitive to developments that significantly affect those sectors, industries, or sub-sectors. An individual sector, industry, or sub-sector of the market may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events. The Fund’s performance could also be affected if the sectors, industries, or sub-sectors do not perform as expected. Alternatively, the lack of exposure to one or more sectors or industries may adversely affect performance. For information about the risks of investing in particular sectors, see the Fund’s Statement of Additional Information.

Sovereign 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. Certain emerging market or developing countries are among the largest debtors to commercial banks and foreign governments. At times, certain emerging market countries have declared moratoria on the payment of principal and interest on external debt. Certain emerging market countries have experienced difficulty in servicing their sovereign debt on a timely basis that led to defaults and the restructuring of certain indebtedness.

The Fund may also invest in obligations issued by supranational entities, such as the World Bank. A supranational entity is financially supported by the governments of one or more countries, has no taxing authority, and is dependent on its members for payments of interest and principal. There is no guarantee that the members will continue to make capital contributions. If such contributions are not made, the 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.

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 the first class of interests, or floating rate certificates, receive tax-exempt interest based on short-term rates and may tender the certificates to the trust at face value. A remarketing agent for the trust is required to attempt to resell any tendered floating rate certificates and if the remarketing agent is unsuccessful, the trust’s liquidity provider must contribute cash to ensure that the tendering holders receive the purchase price of their securities on the repurchase date. Holders of the second class of interests, or residual income certificates (commonly referred to as “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. The distributions from inverse floaters will be reduced (and potentially eliminated) if short-term interest rates increase. Investments in tender option bonds expose the Fund to counterparty risk and leverage risk. Tender option bonds may have some of the same characteristics as an investment in derivatives. 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. In certain instances, a trust may be terminated if, for example, the issuer of the underlying bond defaults on interest payments, the credit rating assigned to the

issuer of the underlying bond is downgraded, or tendered floating rate certificates cannot be resold

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, including due to changes in interest rates, of the securities. Furthermore, not all securities issued by the U.S. government and its agencies and instrumentalities are backed by the full faith and credit of the U.S. Treasury. Some are backed by the issuer’s right to borrow from the U.S. Treasury, while others are backed only by the credit of the issuing agency or instrumentality. These securities carry at least some risk of non-payment or default by the issuer. The maximum potential liability of the issuers of some U.S. government securities may greatly exceed their current resources, including their legal right to support from the U.S. Treasury. It is possible that these issuers will not have the funds to meet their payment obligations in the future. There is no assurance that the U.S. Government will provide financial support to its agencies and instrumentalities if it is not obligated by law to do so.

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

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 closing price and from the prices used by other funds to calculate their NAVs. Investors who purchase or redeem Fund shares on days when the Fund is holding fair-valued securities may receive fewer or more shares, or lower or higher redemption proceeds, than they would have

received if the Fund had not held fair-valued securities or had used a different methodology. The value of foreign securities, certain futures, fixed income securities, and currencies may be materially affected by events after the close of the markets on which they are traded but before the Fund determines its net asset value. The Fund 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. Different pricing services use different valuation methodologies, potentially resulting in different values for the same investments. As a result, if the Fund were to change pricing services, or if a pricing service were to change its valuation methodology, the value of the Fund’s investments could be impacted. The Fund’s ability to value its investments in an accurate and timely manner may be impacted by technological issues and/or errors by third party service providers, such as pricing services or accounting agents.

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

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

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

Information about Additional Risks and Other Practices

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

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

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

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

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

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

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

A Fund may change its goal without shareholder approval.

Management of the Funds

Investment Manager

Neuberger Berman Investment Advisers LLC (“Manager”), located at 1290 Avenue of the Americas, New York, NY 10104, is each Fund’s investment manager and administrator. Neuberger Berman BD LLC (“Distributor”), located at 1290 Avenue of the Americas, New York, NY 10104, is each Fund’s distributor. Pursuant to an investment advisory agreement, the Manager is responsible for choosing a Fund’s investments and handling its day-to-day business. The services provided by the Manager as the investment manager and administrator include, among others, overall responsibility for providing all supervisory, management, and administrative services reasonably necessary for the operation of the Funds, which may include, among others, compliance monitoring, operational and investment risk management, legal and administrative services and portfolio accounting services. The Manager carries out its duties subject to the policies established by the Board of Trustees. The investment advisory agreement establishes the fees a Fund pays to the Manager for its services as the Fund’s investment manager and the expenses paid directly by the Fund. Together, the Neuberger Berman affiliates manage approximately $463 billion in total assets (as of 12/31/2023) and continue an asset management history that began in 1939.

NBIA may engage one or more of foreign affiliates that are not registered under the Investment Advisers Act of 1940, as amended (“participating affiliates”) in accordance with applicable SEC no-action letters. As participating affiliates, whether or not registered with the SEC, the affiliates may provide designated investment personnel to associate with NBIA as “associated persons” of NBIA and perform specific advisory services for NBIA, including services for the Funds, which may involve, among other services,

portfolio management and/or placing orders for securities and other instruments. The designated employees of a participating affiliate act for NBIA and are subject to certain NBIA policies and procedures as well as supervision and periodic monitoring by NBIA. The Funds will pay no additional fees and expenses as a result of any such arrangements.

A discussion regarding the basis for the Board of Trustees’ approval of the Funds’ investment advisory agreements is available in the Funds’ annual report for the fiscal period ended October 31, 2023.

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

Neuberger Berman Strategic Income Fund — Trust Class

YOUR INVESTMENT

Trust Class shares of the Funds generally are available only through financial intermediaries. For certain investors, shares of the Funds are also available directly from Neuberger Berman BD LLC, the Funds’ Distributor (see “Maintaining Your Account”).

Share Prices

Because Trust Class shares of the Funds do not have a sales charge, the price you pay for each share of a Fund is the Fund’s net asset value per share. Similarly, because the Funds do not charge fees for selling shares, your Fund pays you the full share price (net asset value) when you sell shares.

If you use a financial intermediary, that provider may charge fees that are in addition to those described in this prospectus.

The Funds are generally open for business every day the New York Stock Exchange (“Exchange”) is open. The Exchange is generally closed on all national holidays and Good Friday; Fund shares will not be priced on those days or other days on which the Exchange is scheduled to be closed. When the Exchange is closed for unusual reasons, Fund shares will generally not be priced although a Fund may decide to remain open and price Fund shares and in such a case, the Fund would post a notice on www.nb.com.

Each Fund normally calculates its share price on each day the Exchange is open once daily as of 4:00 P.M., Eastern time. In the event of an emergency or other disruption in trading on the Exchange, a Fund’s share price would still normally be determined as of 4:00 P.M., Eastern time. In general, every buy or sell order you place will go through at the next share price calculated after your order has been received in proper form (see “Maintaining Your Account” for information on placing orders). Check with your financial intermediary to find out by what time your order must be received so that it can be processed the same day. Depending on when your financial intermediary accepts orders, it is possible that a Fund’s share price could change on days when you are unable to buy or sell shares.

Because foreign markets may be open on days when U.S. markets are closed, the value of foreign securities owned by a Fund could change on days when you cannot buy or sell Fund shares. Remember, though, any purchase or sale takes place at the next share price calculated after your order is received in proper form.

Share Price Calculations

The net asset value per share of Trust class of a Fund is the total value of Fund assets attributable to shares of that class minus the liabilities attributable to that class, divided by the total number of shares outstanding for that class. Because the value of a Fund’s portfolio securities changes every business day, its share price usually changes as well.

A Fund generally values its investments based upon their last reported sale prices, market quotations, or estimates of value provided by an independent pricing service as of the time as of which the Fund’s share price is calculated. Debt securities and certain derivative instruments that do not trade on an exchange generally are valued by one or more independent pricing services approved by the Manager on the basis of market quotations and in the case of derivatives, market data about the underlying investments. Short-term securities held by a Fund may be valued on the basis of amortized cost, unless other factors indicate that amortized cost is not an accurate estimate of the security’s value. Equity securities (including securities issued by ETFs) and exchange-traded derivative instruments held by a Fund generally are valued by one or more independent pricing services approved by the Manager at the last reported sale price or official closing price or, if there is no reported sale quoted on a principal exchange or market for that security or official closing price, on the basis of market quotations.

Investments in non-exchange traded investment companies are valued using the respective fund’s daily calculated net asset value per share. The prospectuses for these funds explain the circumstances under which the funds will use fair value pricing and the effects of using fair value pricing.

If a valuation for a security is not available from an independent pricing service or if the Manager believes in good faith that the valuation does not reflect the amount a Fund would receive on a current sale of that security, the Fund seeks to obtain quotations from brokers or dealers. If such quotations are not readily available, the Fund may use a fair value estimate made according to methods approved by the Manager. Pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, the Board of Trustees designated the Manager as the Fund’s valuation designee. As the Fund’s valuation designee, the Manager is responsible for determining fair value in good faith for any and all Fund investments. A Fund may also use these methods to value certain types of illiquid securities. Fair value pricing generally

will be used if the market in which a portfolio security trades closes early or if trading in a particular security was halted during the day and did not resume prior to the time as of which a Fund’s share price is calculated.

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

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

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

Trading in securities on many foreign exchanges is normally completed before the Fund calculates its net asset value. In addition, foreign markets may be open on days when U.S. markets are closed. As a result, the value of foreign securities owned by the Fund could change at times or on days when the Fund’s net asset value is not calculated, when Fund shares do not trade, and when sales and redemptions of Fund shares do not occur.

Privileges and Services

If you purchase Trust Class shares directly from the Distributor, you have access to the services listed below. If you purchase shares through a financial intermediary, consult that provider for information about investment services.

Systematic Investments — This plan lets you take advantage of dollar-cost averaging by establishing periodic investments of $100 or more a month. You choose the schedule and amount. Your investment money may come from an eligible money market fund outside the fund family or your bank account.

Systematic Withdrawals — This plan lets you arrange withdrawals of at least $100 from a fund in the fund family on a periodic schedule. You can also set up payments to distribute the full value of an account over a given time. While this service can be helpful to many investors, be aware that it could generate capital gains or losses.

Electronic Bank Transfers — When you sell Fund shares, you can have the money sent to your bank account electronically rather than mailed to you as a check. Please note that your bank must be a member of the Automated Clearing House, or ACH, system.

Internet Access — At www.nb.com, you can make transactions, check your account and access a wealth of information.

FUNDfone^® — Get up-to-date performance and account information through our 24-hour automated service by calling 800-335-9366. If you already have an account with us, you can place orders to buy, sell, or exchange fund shares.

Dollar-Cost Averaging

Systematic investing allows you to take advantage of the principle of dollar-cost averaging. When you make regular investments of a given amount — say, $100 a month — you will end up investing at different share prices over time. When the share price is high, your $100 buys fewer shares; when the share price is low, your $100 buys more shares. Over time, this can help lower the average price you pay per share.

Dollar-cost averaging cannot guarantee you a profit or protect you from losses in a declining market. But it can be beneficial over the long term.

Distributions and Taxes

Distributions — Each Fund pays out to its shareholders any net investment income and net realized capital gains. Ordinarily, each Fund declares income dividends daily and pays them monthly and declares and makes any capital gain distributions once a year (usually in December). Gains from foreign currency transactions, if any, are normally distributed in December. A Fund may make additional distributions, if necessary, to avoid federal income or excise taxes.

Unless you designate otherwise, your distributions, if any, from a Fund will be reinvested in additional Trust Class shares of the Fund. However, if you prefer, you may receive all distributions in cash or reinvest capital gain distributions but receive income dividends in cash. Distributions taken in cash can be sent to you by check or by electronic transfer to a designated bank account or invested in Trust Class shares of another fund in the fund family with the same account registration. To take advantage of one of these options, indicate your choice on your application or contact a Fund in writing or by phone if you bought shares directly. If you use a financial intermediary, you must consult it about whether your income dividends and capital gain distributions from a Fund will be reinvested in additional Trust Class shares of the Fund or paid to you in cash.

How distributions are taxed — Except for tax-advantaged retirement plans and accounts and other tax-exempt investors (collectively “exempt investors”), all Fund distributions you receive are generally taxable to you, regardless of whether you take them in cash or reinvest them in additional Fund shares.

Fund distributions to individual retirement accounts (“IRAs”), Roth IRAs, and qualified retirement plans generally are tax-free. Eventual withdrawals from a Roth IRA also may be tax-free, while withdrawals from other retirement plans and accounts are subject to federal income tax.

Distributions generally are taxable to shareholders other than exempt investors in the year they are received. In some cases, however, distributions received in January are treated for federal income tax purposes as if they had been paid the previous December 31. Your tax statement (see “Taxes and You”) will help clarify this for you.

Distributions of net investment income and the excess of net short-term capital gain over net long-term capital loss (“dividends”) are taxed as ordinary income. It is not expected that any of the Funds’ distributions will be attributable to “qualified dividend income” (generally, dividends a Fund receives on stock of most U.S. and certain foreign corporations), which are subject to maximum federal income tax rates for individual and certain other non-corporate shareholders (each, an “individual shareholder”) that are lower than the maximum rates for ordinary income (“lower maximum rates”).

Distributions of net capital gain (i.e., the excess of net long-term capital gain over net short-term capital loss) are taxed as long-term capital gain and for individual shareholders are subject to the lower maximum rates. The tax treatment of capital gain distributions from a Fund depends on how long the Fund held the securities it sold that generated the gain, not on when you bought your shares of the Fund or whether you reinvested your distributions.

If, for any taxable year, a Fund distributes an amount that exceeds its current earnings and profits (generally, the sum of its investment company taxable income plus net capital gain for that year) — which might result from, among other things, the difference between book and tax accounting treatment of certain derivatives and foreign currency transactions — plus its accumulated earnings and profits, if any, that excess generally will be treated as a return of capital, which will reduce your tax basis in your Fund shares. To the extent that excess is greater than your tax basis, it will be treated as gain from a redemption of your shares (taxed as described below).

Shareholders should review any notice that accompanies a payment of dividends or other distributions to determine whether any portion of the payment represents a return of capital rather than a distribution of a Fund’s net income and/or gains.

How share transactions are taxed — When you sell (redeem) or exchange Fund shares, you generally will realize a taxable gain or loss. An exception, once again, applies to exempt investors. For individual shareholders, any capital gain recognized on a redemption or exchange of Fund shares that have been held for more than one year will qualify for the lower maximum rates.

Additional tax — An individual shareholder’s distributions from a Fund and net gains recognized on redemptions and exchanges of Fund shares are subject to a 3.8% federal tax on the lesser of (1) the individual’s “net investment income” (which generally includes distributions from a Fund and net gains from the disposition of Fund shares) or (2) the excess of the individual’s “modified adjusted gross income” over a specified threshold amount. This tax is in addition to any other taxes due on that income. You should consult your own tax professional regarding the effect, if any, this provision may have on your investment in Fund shares.

Taxes and You

The taxes you actually owe on Fund distributions and share transactions can vary with many factors, such as your marginal tax bracket, how long you held your shares and whether you owe federal alternative minimum tax.

How can you figure out your tax liability on Fund distributions and share transactions? One helpful tool is the tax statement that we or your financial intermediary sends you after the end of each calendar year. It details the distributions you received during the past year and shows their tax status. That statement, or a separate statement from us or your financial intermediary, also covers your share transactions.

Most importantly, consult your tax professional. Everyone’s tax situation is different, and your tax professional should be able to help you answer any questions you may have.

Backup Withholding

A Fund is required to withhold at the backup withholding rate from the money you are otherwise entitled to receive from its distributions and redemption proceeds (regardless of whether you realized a gain or loss) if you are an individual shareholder who fails to provide a correct taxpayer identification number to the Fund. Withholding at that rate also is required from a Fund’s distributions to which you are otherwise entitled if you are an individual shareholder and the Internal Revenue Service tells us that you are subject to backup withholding (1) for failing to properly report the receipt of interest or dividend income or (2) for any other reason.

If you use a financial intermediary, you must supply your signed taxpayer identification number form (generally, Form W-9) to your financial intermediary, and it must supply its taxpayer identification number to us, in order to avoid backup withholding.

Buying Shares Before a Distribution

The money a Fund earns, either as net investment income or as net realized capital gains, is reflected in its share price until it distributes the money. At that time, the amount of the distribution is deducted from the share price. Because of this, if you buy shares of a Fund just before it makes such a distribution, you will end up getting some of your investment back as a taxable distribution. You can avoid this situation by waiting to invest until after the record date for the distribution.

Generally, if you are an exempt investor, there are no current tax consequences to you from distributions.

Basis Determination and Reporting

Your basis in Fund shares that you acquired or acquire after December 31, 2011 (collectively, “Covered Shares”), will be determined in accordance with the Funds’ default basis determination method, which is average cost basis, unless you affirmatively elect in writing (which may be electronic) to use a different basis determination method acceptable to the Internal Revenue Service. The basis determination method may not be changed with respect to a redemption (including a redemption that is part of an exchange) of Covered Shares after the settlement date of the redemption. A Fund must report to the Internal Revenue Service and furnish to its shareholders the basis information for Covered Shares. See “Additional Tax Information” in the Statement of Additional Information for more information about the rules regarding basis determination and a Fund’s reporting obligation. You should consult with your tax professional to determine the best basis determination method for your tax situation and to obtain more information about how the basis determination and reporting rules apply to you.

Maintaining Your Account

When you buy shares — Instructions for buying shares from the Distributor are under “Buying Shares.” See “Financial Intermediaries” if you are buying shares through a financial intermediary. Whenever you make an initial investment in one of the Funds or add to your existing account (except with an automatic investment), you will be sent a statement confirming your transaction if you bought shares directly. Investors who bought shares through a financial intermediary should contact their financial intermediary for information regarding transaction statements. Investment checks must be drawn on a U.S. bank. We cannot accept cash, money orders, starter checks, travelers checks, or other cash equivalents. We do accept Bank Checks and Cashier’s Checks from U.S. Financial Institutions.

When you purchase shares, you will receive the next share price to be calculated after your order has been received in proper form. Purchase orders are deemed “received in proper form” when the Funds’ transfer agent has received payment for the shares. In the

case of certain institutional investors, the Distributor will process purchase orders when received, on the basis of a pre-existing arrangement to make payment by the following morning. In addition, if you have established a systematic investment program (SIP) with one or more of the Funds, your order is deemed “received in proper form” on the date you pre-selected on your SIP application for the systematic investments to occur. Dividends are normally first earned the business day after your purchase order is received in proper form.

Trust Class of each Fund is closed to new investors. Only certain investors are allowed to purchase Trust Class shares of each Fund, as follows:

Shareholders who, by virtue of an investment made through a financial intermediary, are permitted to invest in a class that is generally closed to new investors may have to continue to participate in the same program of fees and services at that financial intermediary to maintain their ability to purchase that class. Please check with your financial intermediary for more information.

When you sell shares — If you bought your shares from the Distributor, instructions for selling shares are under “Selling Shares.” See “Financial Intermediaries” if you want to sell shares you purchased through a financial intermediary. You can place an order to sell some or all of your shares at any time. When you sell shares, you will receive the next share price to be calculated after your order has been received in proper form. Redemption orders are deemed “received in proper form” when the Fund’s transfer agent has received your order to sell.

In some cases, you will have to place your order to sell shares in writing, and you will need a Medallion signature guarantee (see “Medallion Signature Guarantees”).

Dividends are earned through the business day on which your redemption order is received in proper form. Investors redeeming in full will receive earned dividends on the day they sell their shares; investors redeeming a portion of their shares will receive earned dividends on the next applicable monthly distribution date.

When selling shares in an account that you do not intend to close, remember to leave at least $1,000 worth of shares in the account. Otherwise, the Fund has the right to request that you bring the balance back up to the minimum level. If you have not done so within 60 days, we may close your account and redeem the proceeds.

The Funds reserve the right to pay in kind for redemptions. The Funds do not redeem in kind under normal circumstances, but would do so when the Manager or the Board of Trustees determines that it is in the best interests of a Fund’s shareholders as a whole or the transaction is otherwise effected in accordance with procedures adopted by the Board of Trustees.

Uncashed checks — We do not pay interest on uncashed checks from Fund distributions or the sale of Fund shares. We are not responsible for checks after they are sent to you. After allowing a reasonable time for delivery, please call us if you have not received an expected check. While we cannot track a check, we may make arrangements for a replacement. Your financial intermediary may be required to transfer assets related to uncashed checks to a state government under the state’s unclaimed or abandoned property law.

Statements and Confirmations — Please review your account statements and confirmations carefully as soon as you receive them. You must contact us within 30 days if you have any questions or notice any discrepancies. Otherwise, you may adversely affect your right to make a claim about the transaction(s).

When you exchange shares — You can move an investment from one fund to a comparable class of another fund in the fund family (or to an eligible money market fund outside the fund family) through an exchange of shares, or by electing to use your cash distributions from one fund to purchase shares of the other fund. There are three things to remember when making an exchange:

The exchange privilege can be withdrawn from any investor that we believe is trying to “time the market” or is otherwise making exchanges that we judge to be excessive. Frequent exchanges can interfere with Fund management and affect costs and performance for other shareholders. Contact your financial intermediary to see if it allows you to take advantage of the fund exchange program and for its policies to affect an exchange.

In addition, Grandfathered Investors may exchange into Class A shares of a fund in the fund family without paying any applicable sales charges.

See “Additional Exchange Information” in the Statement of Additional Information for information regarding eligible money market funds outside the fund family.

Placing orders by telephone — If you use a financial intermediary, contact your financial intermediary for its policies regarding telephone orders.

Fund investors have the option of placing telephone orders, subject to certain restrictions. This option is available to you unless you indicate on your account application (or in a subsequent letter to us or to SS&C Global Investor & Distribution Solutions, Inc.) that you do not want it.

Whenever we receive a telephone order, we take steps to make sure the order is legitimate. These may include asking for identifying information and recording the call. As long as a Fund and its representatives take reasonable measures to verify the authenticity of calls, investors may be responsible for any losses caused by unauthorized telephone orders.

In unusual circumstances, it may be difficult to place an order by phone. In these cases, consider sending your order by express delivery. You may also use FUNDfone^® or visit our website at www.nb.com.

Proceeds from the sale of shares — The proceeds from the shares you sell are typically sent out the next business day after your order is executed, and nearly always within seven days regardless of payment type. When you sell shares through your financial intermediary, contact your provider to find out when proceeds will be sent to you. There are two cases in which proceeds may be delayed beyond this time:

If you think you may need to sell shares soon after buying them, you can avoid the check clearing time by investing by wire.

The Funds do not issue certificates for shares.

The Funds typically expect to meet redemption requests, under both normal and stressed market conditions, by redeeming cash and cash equivalent portfolio holdings and/or selling portfolio securities or other instruments. As described further above and in the Funds’ Statement of Additional Information, the Funds also reserve the right to redeem an investor’s shares in kind (i.e., providing investors with portfolio securities instead of cash), in whole or in part to meet redemption requests in stressed market conditions and other appropriate circumstances.

The Funds reserve the right to pay in kind for redemptions. A Fund also may elect to honor a shareholder’s request for the Fund to pay in kind for redemptions in an attempt to manage any liquidity needs, to manage and optimize its portfolio composition, to offset transaction costs associated with portfolio transactions, and/or to more efficiently manage its portfolio. The securities provided to investors in an in-kind redemption may be a pro-rata portion of the Fund’s portfolio or a non-pro-rata portion of the Fund’s portfolio selected by the Manager based upon various circumstances and subject to the Fund’s policies and procedures and

any applicable laws or regulations. If the securities provided to investors in an in-kind redemption are a non-pro-rata portion of the Fund’s portfolio, it will only include securities that have been disclosed in the Fund’s most recent public portfolio holdings disclosure.

Redemptions in kind may cause you to incur transaction costs to the extent you dispose of the securities redeemed in kind and the value of the securities redeemed in kind may decrease between the time of redemption and the time of such sale. The Funds may also borrow under any available line of credit and other available methods to meet redemption requests in both normal and stressed market conditions and other appropriate circumstances.

Other policies — Under certain circumstances, which may include normal and stressed market conditions, the Funds reserve the right to:

Important information regarding unclaimed/abandoned property — If your financial intermediary (or, if you bought your shares directly, the Distributor) is unable to locate you, then it is required by law to determine whether your account(s) must be deemed “unclaimed” or “abandoned.” Your financial intermediary (or the Distributor) is required to transfer (or escheat) unclaimed or abandoned property to the appropriate state government in accordance with state law. Your account(s) may also be deemed “unclaimed” or “abandoned” and subsequently transferred to the appropriate state government if no activity (as defined by that state) occurs within the account(s) during the period of time specified by state law or if checks related to the account(s) remain uncashed. Your last known address of record determines which state has jurisdiction.

It is your responsibility to ensure that your financial intermediary (or the Distributor) maintains a correct address for your account(s). An incorrect address may cause your account statements and other mailings to be returned as undeliverable. Neither the Distributor nor a Fund nor its transfer agent will be liable to investors or their representatives for good faith compliance with state unclaimed or abandoned property (escheatment) laws. If you use a financial intermediary, contact that provider regarding applicable state escheatment laws.

Medallion Signature Guarantees

You may need a Medallion signature guarantee when you sell shares directly or through a financial intermediary. A Medallion signature guarantee is a guarantee that your signature is authentic.

Medallion signature guarantees are required for a variety of transactions including requests for changes to your account or to the instructions for distribution of proceeds. We reserve the right to require a Medallion signature guarantee on any transaction at our discretion.

Most banks, brokers, and other financial institutions can provide you with one. Some may charge a fee; others may not, particularly if you are a customer of theirs.

A notarized signature from a notary public is not a Medallion signature guarantee.

Financial Intermediaries

The Trust Class shares available in this prospectus may be purchased through certain financial intermediaries such as banks, brokerage firms, workplace retirement programs, and financial advisers.

The fees and policies outlined in this prospectus are set by the Funds and by the Distributor. However, if you use a financial intermediary, most of the information you will need for managing your investment will come from that provider. This includes information on how to buy and sell shares, investor services, and additional policies.

If you use a financial intermediary, contact that provider to buy or sell shares of the Funds described in this prospectus.

Most financial intermediaries allow you to take advantage of the fund exchange program, which is designed for moving an investment from one fund to a comparable class of another fund in the fund family if made available by that financial intermediary through an exchange of shares.

In exchange for the services it offers, your financial intermediary may charge fees that are in addition to those described in this prospectus.

Additional Payments to Financial Intermediaries

The Distributor and/or its affiliates pay additional compensation, out of their own resources and not as an expense of the Funds, to certain financial intermediaries, including affiliates, in connection with the sale, distribution, retention and/or servicing of Fund shares. The amount of these payments may be substantial and may differ among financial intermediaries based on, for example, the level or type of services provided by a financial intermediary. These payments are in addition to any fees paid to compensate financial intermediaries for providing distribution related services to the Funds and/or administrative or shareholder services to Fund shareholders. These arrangements are separately negotiated between the Distributor and/or its affiliates, and the recipients of these payments or their affiliates. If your financial intermediary receives such payments, these payments may provide an incentive for the financial intermediary to make the Funds’ shares available to you or recommend the Funds. If you have purchased shares of a Fund through a financial intermediary, please speak with your financial intermediary to learn more about any payments it receives from the Distributor and/or its affiliates, as well as fees and/or commissions the financial intermediary charges. You should also consult disclosures made by your financial intermediary at the time of purchase. Any such payments by the Distributor or its affiliates will not change the net asset value or the price of a Fund’s shares. For more information, please see the Funds’ Statement of Additional Information.

Distribution and Shareholder Servicing Fees

Each Fund has adopted a plan pursuant to Rule 12b-1 under the Investment Company Act of 1940. Under the plan, each Fund’s Trust Class shares pays the Distributor a fee at an annual rate of 0.10% of its average net assets to compensate financial intermediaries for providing distribution related services to the Fund and/or administrative or shareholder services to Fund shareholders. The Distributor may also retain part of this fee as compensation for providing these services. These fees increase the cost of investment. Because these fees are paid out of a Fund’s assets on an on-going basis, over the long term they could result in higher overall costs than other types of sales charges.

Information Required from New Accounts

To help the U.S. government fight the funding of terrorism and money laundering activities, federal law requires all financial institutions to obtain, verify, and record information that identifies each person who opens an account.

When you open an account, we (which may include your financial intermediary acting on our behalf) will require your name, address, date of birth, and social security number or other taxpayer identification number. We may also require other identifying documents. If we cannot verify the information you supply to us or if it is incomplete, we may be required to return your funds or redeem your account.

If you are a direct investor buying or selling shares, instructions are provided in the following charts. Investors buying or selling shares through a financial intermediary should contact it for instructions.

Retirement Plans and Accounts

We offer investors a number of tax-advantaged plans and accounts for retirement saving:

Traditional IRAs allow money to grow tax-deferred until you take it out, usually at or after retirement. Contributions are deductible for some investors, but even when they are not, an IRA can be beneficial.

Roth IRAs offer tax-free growth like a traditional IRA, but instead of tax-deductible contributions, the withdrawals are tax-free for investors who meet certain requirements.

Also available: SEP-IRA, SIMPLE-IRA, Keogh, and other types of plans. Coverdell Education Savings Accounts (formerly Education IRAs), though not for retirement savings, also are available. Consult your tax professional to find out which types of plans or accounts may be beneficial for you. Call 800-366-6264 for information on any Neuberger Berman retirement plan or account.

Internet Connection

If you use a financial intermediary, contact that provider about the services and information it provides on the Internet.

Investors with Internet access can enjoy many valuable and time-saving features by visiting us at www.nb.com.

The site offers more complete information on our funds, including current performance data, portfolio manager interviews, tax information plus educational articles, news and analysis. You can tailor the site so it serves up information that is most relevant to you.

As a Fund shareholder who bought shares directly from the Distributor, you can use the web site to access account information and even make secure transactions — 24 hours a day.

Market Timing Policy

Frequent purchases, exchanges and redemptions of Fund shares (“market-timing activities”) can interfere with effective Fund management and adversely affect Fund performance in various ways, including by requiring a portfolio manager to liquidate portfolio holdings at a disadvantageous time or price, by increasing costs (such as brokerage costs) to a Fund by requiring a portfolio manager to effect more frequent purchases and sales of portfolio securities, and possibly by requiring a portfolio manager to keep a larger portion of Fund assets in cash, all of which could adversely affect the interests of long-term shareholders. To discourage market-timing activities by Fund shareholders, the Board of Trustees has adopted market-timing policies and has approved the procedures of the principal underwriter for implementing those policies. As described earlier in this prospectus, pursuant to such policies, the exchange privilege can be withdrawn from any investor that is believed to be “timing the market” or is otherwise making exchanges judged to be excessive. In furtherance of these policies, under certain circumstances, the Funds reserve the right to reject any exchange or purchase order; change, suspend or revoke the exchange privilege; or suspend the telephone order privilege.

The Manager applies the Funds’ policies and procedures with respect to market-timing activities by monitoring trading activity in the Funds, identifying excessive trading patterns, and warning or prohibiting shareholders who trade excessively from making further purchases or exchanges of Fund shares. These policies and procedures are applied consistently to all shareholders. Although the Funds make efforts to monitor for market-timing activities, the ability of the Funds to monitor trades that are placed by the underlying shareholders of omnibus accounts maintained by brokers, retirement plan accounts and other approved financial intermediaries may be limited in those instances in which the financial intermediary maintains the underlying shareholder accounts. Accordingly, there can be no assurance that the Funds will be able to eliminate all market-timing activities.

Portfolio Holdings Policy

A description of the Funds’ policies and procedures with respect to the disclosure of the Funds’ portfolio holdings is available in the Funds’ Statement of Additional Information.

The complete portfolio holdings for each Fund are available at www.nb.com/holdings (click on the tab with the name of the relevant Fund). The complete portfolio holdings for each Fund are generally posted 15-30 days after each month-end.

Each Fund’s complete portfolio holdings will remain available at this website until the subsequent month-end holdings have been posted. Complete portfolio holdings for the Funds will also be available in reports on Form N-PORT and Form N-CSR filed with the SEC. Historical portfolio holdings are available upon request.

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

Fund Structure

Each Fund offers one or more classes of shares that have identical investment programs, but may have different fee waivers and different arrangements for distribution and shareholder servicing and, consequently, different expenses. Shares of a class to which a fee waiver applies may not be available to all investors in a Fund. Rather, they will be made available to investors meeting eligibility criteria outlined in the Prospectuses for such share classes. This prospectus relates solely to the Trust Class shares of the Funds.
