Introduction to the Funds

Each Fund is a series of the AB Bond Fund, Inc. (the “Company”). The Company is an open-end investment company.

Except as otherwise noted, each Fund’s investment objective and policies described below are not “fundamental policies” within the meaning of the Investment Company Act of 1940, as amended (the “1940 Act”), and may, therefore, be changed by the Board of Directors of the Company (the “Board” or the “Directors”) without shareholder approval. However, no Fund will change its investment objective without at least 60 days’ prior written notice to shareholders. There is no guarantee that a Fund will achieve its investment objective. Whenever any investment policy or restriction states a percentage of a Fund’s assets that may be invested in any security or other asset, it is intended that such percentage limitation be determined immediately after and as a result of the Fund’s acquisition of such securities or other assets. Accordingly, except with respect to borrowing, any later increases or decreases in percentage beyond the specified limitations resulting from a change in values or net assets will not be considered a violation of this percentage limitation.

Additional Investment Policies and Practices

The following information about the Funds’ investment policies and practices supplements the information set forth in the Prospectus.

Contingent Value Rights

The Funds may hold contingent value rights (“CVRs”). A CVR gives the holder the right to receive an amount, which may be a fixed amount or a variable amount determined by a formula, in the event that a specified corporate action or other business event or trigger occurs (or does not occur) during the term of the CVR. CVRs are often subject to an expiration date. CVRs may be awarded to investors in the context of a corporate acquisition or major restructuring, such as a reorganization pursuant to Chapter 11 of the U.S. Bankruptcy Code or other bankruptcy reorganization. For example, investors in an acquired or reorganized company may receive CVRs that enable the investor to receive additional shares of the acquiring company in the event that the acquiring company’s share price falls below a certain level by a specified date, or to receive cash payments and/or securities in the event of a future sale or liquidation event involving the company by a specified date. CVRs generally do not entitle a holder to dividends or voting rights with respect to the underlying company and do not represent any rights in the assets of the issuing company. Risks associated with the use of CVRs are generally similar to risks associated with the use of options, such as the risk that the required trigger does not occur prior to a CVR’s expiration, causing the CVR to expire with no value. CVRs also present liquidity risk, as they may not be registered under the federal securities laws or may otherwise be non-transferable or difficult to transfer, as well as counterparty risk and credit risk. Further, because CVRs are valued based on the likelihood of the occurrence of a trigger, valuation often requires subjective modeling and judgment, which increases the risk of mispricing or improper valuation.

Derivatives

A Fund may, but is not required to, use derivatives for hedging or other risk management purposes or as part of its investment strategies. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index. These assets, rates and indices may include bonds, stocks, mortgages, commodities (physical and intangible), interest rates, currency exchange rates, bond indices and stock indices.

There are four principal types of derivatives — options, futures contracts, forwards and swaps. These principal types of derivative instruments, as well as the ways they may be used by a Fund, are described below. Derivatives include listed and cleared transactions where a Fund’s derivative trade counterparty is an exchange or clearinghouse, and non-cleared bilateral “over-the-counter” (“OTC”) transactions that are privately negotiated and where the Fund’s derivative trade counterparty is a financial institution. Exchange-traded or cleared derivatives transactions tend to be subject to less counterparty credit risk than those that are bilateral and privately negotiated. The Funds may use derivatives to earn income and enhance returns, to hedge or adjust the risk profile of a portfolio and either to replace more traditional direct investments or to obtain exposure to otherwise inaccessible markets.

Forward Contracts. A forward contract, which may be standardized and exchange-traded or customized and privately-negotiated, is an agreement for one party to buy, and the other party to sell, a specific quantity of an underlying security, currency, commodity or other asset for an agreed-upon price at a future date. A forward contract generally is settled by physical delivery of the security, commodity or other tangible asset underlying the forward contract to an agreed-upon location at a future date (rather than settled by cash) or is rolled forward into a new forward contract. Non-deliverable forwards (“NDFs”) specify a cash payment upon maturity.

Futures Contracts and Options on Futures Contracts. A futures contract is an agreement that obligates the buyer to buy and the seller to sell a specified quantity of an underlying asset (or settle for cash the value of a contract based on an underlying asset, rate or index) at a specific price on the contract maturity date. Options on futures contracts are options that call for the delivery of futures contracts upon exercise. Futures contracts are standardized, exchange-traded instruments and are fungible (i.e., considered to be perfect substitutes for each other). This fungibility allows futures contracts to be readily offset or canceled through the acquisition of equal but opposite positions, which is the primary method by which futures contracts are liquidated. A cash-settled futures contract does not require physical delivery of the underlying asset but instead is settled for cash equal to the difference between the values of the contract on the date it is entered into and its maturity date.

Options. An option, which may be standardized and exchange-traded or customized and privately negotiated, is an agreement that, for a premium payment or fee, gives the option holder (the buyer) the right but not the obligation to buy (a “call”) or sell (a “put”) the underlying asset (or settle for cash an amount based on an underlying asset, rate or index) at a specified price (the exercise price) during a period of time or on a specified date. Likewise, when an option is exercised the writer of the option is obligated to sell (in the case of a call option) or to purchase (in the case of a put option) the underlying asset (or settle for cash an amount based on an underlying asset, rate or index).

Swaps. A swap is an agreement that obligates two parties to exchange a series of cash flows at specified intervals (payment dates) based upon or calculated by reference to changes in specified prices or rates (e.g., interest rates in the case of interest rate swaps, currency exchange rates in the case of currency swaps) for a specified amount of an underlying asset (the “notional” principal amount). Most swaps are entered into on a net basis (i.e., the two payment streams are netted out, with a Fund receiving or paying, as the case may be, only the net amount of the two payments). Generally, the notional principal amount is used solely to calculate the payment streams but is not exchanged. Pursuant to CFTC regulations, certain standardized swaps, including certain interest rate swaps and credit default swaps, are subject to mandatory central clearing and are required to be executed through a regulated swap execution facility. Cleared swaps are transacted through futures commission merchants (“FCMs”) that are members of central clearinghouses with the clearinghouse serving as central counterparty, similar to transactions in futures contracts. Funds post initial and variation margin to support their obligations under cleared swaps by making payments to their clearing member FCMs. Central clearing is intended to reduce counterparty credit risks and increase liquidity, but central clearing does not make swap transactions risk free. The Securities and Exchange Commission (“Commission”) may adopt similar clearing and execution requirements in respect of certain security-based swaps under its jurisdiction. Privately negotiated swap agreements are two-party contracts entered into primarily by institutional investors and are not cleared through a third party, nor are these required to be executed on a regulated swap execution facility.

Risks of Derivatives and Other Regulatory Issues. Investment techniques employing such derivatives involve risks different from, and, in certain cases, greater than, the risks presented by more traditional investments. Following is a general discussion of important risk factors and issues concerning the use of derivatives.

-- Market Risk. This is the general risk attendant to all investments that the value of a particular investment will change in a way detrimental to a Fund’s interest.

-- Management Risk. Derivative products are highly specialized instruments that require investment techniques and risk analyses different from those associated with stocks and bonds. The use of a derivative requires an understanding not only of the underlying instrument but also of the derivative itself, without the benefit of observing the performance of the derivative under all possible market conditions. In particular, the use and complexity of derivatives require the maintenance of adequate controls to monitor the transactions entered into, the ability to assess the risk that a derivative adds to a Fund’s investment portfolio, and the ability to forecast price, interest rate or currency exchange rate movements correctly.

-- Credit Risk. This is the risk that a loss may be sustained by a Fund as a result of the failure of another party to a derivative (usually referred to as a “counterparty”) to comply with the terms of the derivative contract. The credit risk for derivatives traded on an exchange or through a clearinghouse is generally less than for uncleared OTC derivatives, since the performance of the exchange or clearinghouse, which is the issuer or

counterparty to each derivative, is supported by all of the members of such exchange or clearinghouse. The performance of an exchange or clearinghouse is further supported by a daily payment system (i.e., margin requirements) operated by the exchange or clearinghouse in order to reduce overall credit risk. There is no similar intermediary support for uncleared OTC derivatives. Therefore, a Fund will effect transactions in uncleared OTC derivatives only with investment dealers and other financial institutions (such as commercial banks) deemed creditworthy by AllianceBernstein L.P., the Funds’ adviser (the “Adviser”), and the Adviser has adopted procedures for monitoring the creditworthiness of such entities.

-- Counterparty Risk. The value of an OTC derivative will depend on the ability and willingness of a Fund’s counterparty to perform its obligations under the transaction. If the counterparty defaults, a Fund will have contractual remedies but may choose not to enforce them to avoid the cost and unpredictability of legal proceedings. In addition, if a counterparty fails to meet its contractual obligations, a Fund could miss investment opportunities or otherwise be required to retain investments it would prefer to sell, resulting in losses for the Fund. Participants in OTC derivatives markets generally are not subject to the same level of credit evaluation and regulatory oversight as are exchanges or clearinghouses. As a result, OTC derivatives generally expose a Fund to greater counterparty risk than derivatives traded on an exchange or through a clearinghouse.

Recent regulations affecting derivatives transactions require certain standardized derivatives, including many types of swaps, to be subject to mandatory central clearing. Under these requirements, a central clearing organization is substituted as the counterparty to each side of the derivatives transaction. Each party to derivatives transactions is required to maintain its positions with a clearing organization through one or more clearing brokers. Central clearing is intended to reduce, but not eliminate, counterparty risk. A Fund is subject to the risk that its clearing member or clearing organization will itself be unable to perform its obligations. A Fund may also face the indirect risk of the failure of another clearing member customer to meet its obligations to the clearing member, causing a default by the clearing member on its obligations to the clearinghouse.

-- Illiquid Investments Risk. Illiquid investments risk exists when a particular instrument is difficult to purchase, sell or otherwise liquidate. If a derivative transaction is particularly large or if the relevant market is illiquid (as is the case with many privately negotiated derivatives), it may not be possible to initiate a transaction or liquidate a position at an advantageous price.

-- Leverage Risk. Since many derivatives have a leverage component, adverse changes in the value or level of the underlying asset, rate or index can result in a loss substantially greater than the amount

invested in the derivative itself. In the case of swaps, the risk of loss generally is related to a notional principal amount, even if the parties have not made any initial investment. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment.

-- Regulatory Risk. Various U.S. Government entities, including the Commodity Futures Trading Commission (“CFTC”) and the Commission, are in the process of adopting and implementing additional regulations governing derivatives markets required by, among other things, the Dodd-Frank Act, including clearing as discussed above, margin, reporting and registration requirements. In addition, the Commission has adopted Rule 18f-4 under the 1940 Act, which governs the use of derivatives and certain other forms of leverage by registered investment companies. Rule 18f-4 requires certain funds, among other things, to adopt a comprehensive derivatives risk management program, appoint a derivatives risk manager and comply with a limit on fund leverage risk based on value-at-risk, or “VaR.” Funds that use derivatives in a limited amount are not subject to the full requirements of Rule 18f-4. In addition, Congress, various exchanges and regulatory and self-regulatory authorities have undertaken reviews of futures, options and swaps markets in light of market volatility. Among the actions that have been taken or proposed to be taken are new limits and reporting requirements for speculative positions new or more stringent daily price fluctuation limits, and increased margin requirements for various types of futures. These regulations and actions may adversely affect a Fund’s ability to execute its investment strategy.

The CFTC has also issued rules requiring certain OTC derivatives transactions that fall within its jurisdiction to be executed through a regulated securities, futures or swap exchange or execution facility. Such requirements may make it more difficult or costly for a Fund to enter into highly tailored or customized transactions. They may also render certain strategies in which a Fund may otherwise engage impossible or so costly that they will not be economical to implement. If a Fund decides to become a direct member of one or more swap exchange or execution facilities, it will be subject to all of the rules of the exchange or execution facility.

European regulation of the derivatives market is also relevant to the extent a Fund engages in derivatives transactions with a counterparty that is subject to the European Market Infrastructure Regulation (“EMIR”). EMIR introduced uniform requirements in respect of OTC derivative contracts by requiring certain “eligible” OTC derivatives contracts to be submitted for clearing to regulated central clearing counterparties and by mandating the reporting of certain details of OTC derivatives contracts to trade repositories. In addition, EMIR imposes risk mitigation requirements, including requiring appropriate procedures and arrangements to measure, monitor and mitigate operational and counterparty credit risk in respect of OTC derivatives contracts which are not subject to mandatory clearing.

These risk mitigation requirements include the exchange, and potentially the segregation, of collateral by the parties, including by a Fund. While many of the obligations under EMIR have come into force, a number of other requirements have not yet come into force or are subject to phase-in periods, and certain key issues have not been resolved. It is therefore not fully clear how the OTC derivatives market will ultimately adapt to the evolving European regulatory regime for OTC derivatives.

-- Other Risks. Other risks in using derivatives include the risk of mispricing or improper valuation of derivatives and the inability of derivatives to correlate perfectly with underlying assets, rates and indices. Many derivatives, in particular privately negotiated derivatives, are complex and often valued subjectively. Improper valuations can result in increased cash payment requirements to counterparties or a loss of value to a Fund. Derivatives do not always perfectly or even highly correlate with or track the value of the assets, rates or indices they are designed to closely track. Consequently, a Fund’s use of derivatives may not always be an effective means of, and sometimes could be counterproductive to, furthering the Fund’s investment objective.

Other. A Fund may purchase and sell derivative instruments only to the extent that such activities are consistent with the requirements of the Commodity Exchange Act (“CEA”) and the rules adopted by the CFTC thereunder. Under CFTC rules, a registered investment company that conducts more than a certain amount of trading in futures contracts, commodity options, certain swaps and other commodity interests is a commodity pool and its adviser must register as a commodity pool operator (“CPO”). Under such rules, registered investment companies that are commodity pools are subject to additional recordkeeping, reporting and disclosure requirements. The Adviser, with respect to the Funds, except All Market Real Return Portfolio, has claimed an exclusion from the definition of CPO under CFTC Rule 4.5 under the CEA based on the extent of the Funds’ derivatives use and such Funds are not currently subject to these recordkeeping, reporting and disclosure requirements. The trading exemption in Rule 4.5 is not available to All Market Real Return Portfolio, and the Adviser is the registered CPO with respect to that Fund, which must comply with certain recordkeeping, reporting and disclosure requirements but, under rules adopted by the CFTC, compliance with Commission disclosure and filing requirements will, for the most part, constitute compliance with comparable CFTC requirements.

Use of Options, Futures Contracts, Forwards and Swaps by a Fund

—Forward Currency Exchange Contracts. A forward currency exchange contract is an obligation by one party to buy, and the other party to sell, a specific amount of a currency for an agreed-upon price at a future date. A forward currency exchange contract may result in the delivery of the underlying asset upon maturity of the contract in return for the agreed-upon payment. NDFs specify a cash payment upon maturity. NDFs are normally used when the market for physical settlement of the currency is underdeveloped, heavily regulated or highly taxed.

Bond Inflation Strategy and All Market Real Return Portfolio may, for example, enter into forward currency exchange contracts to attempt to minimize the risk to the Funds from

adverse changes in the relationship between the U.S. Dollar and other currencies. A Fund may purchase or sell forward currency exchange contracts for hedging purposes similar to those described below in connection with its transactions in foreign currency futures contracts. A Fund may also purchase or sell forward currency exchange contracts for non-hedging purposes as a means of making direct investments in foreign currencies, as described below under “Currency Transactions”.

If a hedging transaction in forward currency exchange contracts is successful, the decline in the value of portfolio securities or the increase in the cost of securities to be acquired may be offset, at least in part, by profits on the forward currency exchange contract. Nevertheless, by entering into such forward currency exchange contracts, the Funds may be required to forgo all or a portion of the benefits which otherwise could have been obtained from favorable movements in exchange rates.

A Fund may use forward currency exchange contracts to seek to increase total return when the Adviser anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund and do not present attractive investment opportunities. For example, the Fund may enter into a foreign currency exchange contract to purchase a currency if the Adviser expects the currency to increase in value. The Fund would recognize a gain if the market value of the currency is more than the contract value of the currency at the time of settlement of the contract. Similarly, a Fund may enter into a foreign currency exchange contract to sell a currency if the Adviser expects the currency to decrease in value. The Fund would recognize a gain if the market value of the currency is less than the contract value of the currency at the time of settlement of the contract.

The cost of engaging in forward currency exchange contracts varies with such factors as the currencies involved, the length of the contract period and the market conditions then prevailing. Since transactions in foreign currencies are usually conducted on a principal basis, no fees or commissions are involved.

—Options on Securities. A Fund may write and purchase call and put options on securities, including U.S. government securities and municipal securities. In purchasing an option on securities, a Fund would be in a position to realize a gain if, during the option period, the price of the underlying securities increased (in the case of a call) or decreased (in the case of a put) by an amount in excess of the premium paid; otherwise the Fund would experience a loss not greater than the premium paid for the option. Thus, a Fund would realize a loss if the price of the underlying security declined or remained the same (in the case of a call) or increased or remained the same (in the case of a put) or otherwise did not increase (in the case of a put) or decrease (in the case of a call) by more than the amount of the premium. If a put or call option purchased by a Fund were permitted to expire without being sold or exercised, its premium would represent a loss to the Fund.

A Fund may also purchase call options to hedge against an increase in the price of securities that the Fund anticipates purchasing in the future. If such increase occurs, the call option will permit the Fund to purchase the securities at the exercise price, or to close out the options at a profit. The premium paid for the call option plus any transaction costs will reduce the benefit, if any, realized by the Fund upon exercise of the option, and, unless the price of the

underlying security rises sufficiently, the option may expire worthless to the Fund and the Fund will suffer a loss on the transaction to the extent of the premium paid.

A Fund may purchase put options to hedge against a decline in the value of portfolio securities. If such decline occurs, the put options will permit the Fund to sell the securities at the exercise price or to close out the options at a profit. By using put options in this way, the Fund will reduce any profit it might otherwise have realized on the underlying security by the amount of the premium paid for the put option and by transaction costs.

A Fund may write a put or call option in return for a premium, which is retained by the Fund whether or not the option is exercised. A Fund may write covered options or uncovered options. A call option written by a Fund is “covered” if the Fund owns the underlying security, has an absolute and immediate right to acquire that security upon conversion or exchange of another security it holds, or holds a call option on the underlying security with an exercise price equal to or less than the call option it has written. A put option written by a Fund is covered if the Fund holds a put option on the underlying securities with an exercise price equal to or greater than the put option it has written. Uncovered options or “naked options” are riskier than covered options. For example, if a Fund wrote a naked call option and the price of the underlying security increased, the Fund would have to purchase the underlying security for delivery to the call buyer and sustain a loss, which could be substantial, equal to the difference between the option price and the market price of the security.

A Fund may also, as an example, write combinations of put and call options on the same security, known as “straddles”, with the same exercise and expiration date. By writing a straddle, the Fund undertakes a simultaneous obligation to sell and purchase the same security in the event that one of the options is exercised. If the price of the security subsequently rises above the exercise price, the call will likely be exercised and the Fund will be required to sell the underlying security at or below market price. This loss may be offset, however, in whole or part, by the premiums received on the writing of the two options. Conversely, if the price of the security declines by a sufficient amount, the put will likely be exercised. The writing of straddles will likely be effective, therefore, only where the price of the security remains stable and neither the call nor the put is exercised. In those instances where one of the options is exercised, the loss on the purchase or sale of the underlying security may exceed the amount of the premiums received.

By writing a call option, a Fund limits its opportunity to profit from any increase in the market value of the underlying security above the exercise price of the option. By writing a put option, a Fund assumes the risk that it may be required to purchase the underlying security for an exercise price above its then current market value, resulting in a capital loss unless the security subsequently appreciates in value. Where options are written for hedging purposes, such transactions constitute only a partial hedge against declines in the value of portfolio securities or against increases in the value of securities to be acquired, up to the amount of the premium.

The Funds may purchase or write options on securities of the types in which they are permitted to invest in privately-negotiated (i.e., OTC) transactions. Options purchased or written in negotiated transactions may be illiquid and it may not be possible for the Funds to effect a closing transaction at a time when the Adviser believes it would be advantageous to do so.

—Options on Securities Indices. An option on a securities index is similar to an option on a security except that, rather than taking or making delivery of a security at a specified price, an option on a securities index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the chosen index is greater than (in the case of a call) or less than (in the case of a put) the exercise price of the option.

A Fund may write (sell) call and put options and purchase call and put options on securities indices. If a Fund purchases put options on securities indices to hedge its investments against a decline in the value of portfolio securities, it will seek to offset a decline in the value of securities it owns through appreciation of the put option. If the value of the Fund’s investments does not decline as anticipated, or if the value of the option does not increase, the Fund’s loss will be limited to the premium paid for the option. The success of this strategy will largely depend on the accuracy of the correlation between the changes in value of the index and the changes in value of the Fund’s security holdings.

A Fund may also write put or call options on securities indices to, among other things, earn income. If the value of the chosen index declines below the exercise price of the put option, the Fund has the risk of loss of the amount of the difference between the exercise price and the closing level of the chosen index, which it would be required to pay to the buyer of the put option and which may not be offset by the premium it received upon sale of the put option. Similarly, if the value of the index is higher than the exercise price of the call option, the Fund has the risk of loss of the amount of the difference between the exercise price and the closing level of the chosen index, which may not be offset by the premium it received upon sale of the call option. If the value of the securities index is significantly below or above the exercise price of the written option, the Fund could experience a substantial loss.

The purchase of call options on securities indices may be used by a Fund to attempt to reduce the risk of missing a broad market advance, or an advance in an industry or market segment, at a time when the Fund holds uninvested cash or short-term debt securities awaiting investment. When purchasing call options for this purpose, the Fund will also bear the risk of losing all or a portion of the premium paid if the value of the index does not rise. The purchase of call options on stock indices when a Fund is substantially fully invested is a form of leverage, up to the amount of the premium and related transaction costs, and involves risks of loss and of increased volatility similar to those involved in purchasing call options on securities the Fund owns.

—Options on Foreign Currencies. Bond Inflation Strategy and All Market Real Return Portfolio may purchase and write options on foreign currencies for hedging and non-hedging purposes. For example, a decline in the dollar value of a foreign currency in which portfolio securities are denominated will reduce the dollar value of such securities, even if their value in the foreign currency remains constant. In order to protect against such diminutions in the value of portfolio securities, the Funds may purchase put options on the foreign currency. If the value of the currency does decline, the Funds will have the right to sell such currency for a fixed amount in dollars and could thereby offset, in whole or in part, the adverse effect on its portfolio which otherwise would have resulted.

Conversely, where a rise in the dollar value of a currency in which securities to be acquired are denominated is projected, thereby increasing the cost of such securities, the Fund may purchase call options thereon. The purchase of such options could offset, at least partially, the effects of the adverse movements in exchange rates. As in the case of other types of options, however, the benefit to the Fund from purchases of foreign currency options will be reduced by the amount of the premium and related transaction costs. In addition, where currency exchange rates do not move in the direction or to the extent anticipated, the Fund could sustain losses on transactions in foreign currency options which would require it to forgo a portion or all of the benefits of advantageous changes in such rates.

Bond Inflation Strategy and All Market Real Return Portfolio may write options on foreign currencies for hedging purposes or in an effort to increase returns. For example, where the Funds anticipate a decline in the dollar value of non-U.S. Dollar-denominated securities due to adverse fluctuations in exchange rates they could, instead of purchasing a put option, write a call option on the relevant currency. If the expected decline occurs, the option will most likely not be exercised, and the diminution in value of portfolio securities could be offset by the amount of the premium received.

Similarly, instead of purchasing a call option to hedge against an anticipated increase in the dollar cost of securities to be acquired, the Fund could write a put option on the relevant currency, which, if rates move in the manner projected, will expire unexercised and allow the Fund to hedge such increased cost up to the amount of the premium. As in the case of other types of options, however, the writing of a foreign currency option will constitute only a partial hedge up to the amount of the premium, and only if rates move in the expected direction. If this does not occur, the option may be exercised and the Fund will be required to purchase or sell the underlying currency at a loss which may not be offset by the amount of the premium. Through the writing of options on foreign currencies, the Fund also may be required to forgo all or a portion of the benefits that might otherwise have been obtained from favorable movements in exchange rates.

In addition to using options for the hedging purposes described above, Bond Inflation Strategy and All Market Real Return Portfolio may also invest in options on foreign currencies for non-hedging purposes as a means of making direct investments in foreign currencies. The Funds may use options on currency to seek to increase total return when the Adviser anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund and do not present attractive investment opportunities. For example, each Fund may purchase call options in anticipation of an increase in the market value of a currency. The Fund would ordinarily realize a gain if, during the option period, the value of such currency exceeded the sum of the exercise price, the premium paid and transaction costs. Otherwise, the Fund would realize no gain or a loss on the purchase of the call option. Put options may be purchased by the Fund for the purpose of benefiting from a decline in the value of a currency that the Fund does not own. The Fund would normally realize a gain if, during the option period, the value of the underlying currency decreased below the exercise price sufficiently to more than cover the premium and transaction costs. Otherwise, the Fund would realize no gain or loss on the purchase of the put option. For additional information on the use of options on foreign currencies for non-hedging purposes, see “Currency Transactions” below.

Special Risks Associated with Options on Currencies. An exchange-traded options position may be closed out only on an options exchange that provides a secondary market for an option of the same series. Although Bond Inflation Strategy and All Market Real Return Portfolio will generally purchase or sell options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market on an exchange will exist for any particular option, or at any particular time. For some options, no secondary market on an exchange may exist. In such event, it might not be possible to effect closing transactions in particular options, with the result that the Fund would have to exercise its options in order to realize any profit and would incur transaction costs on the purchase or sale of the underlying currency.

—Futures Contracts and Options on Futures Contracts. Futures contracts that a Fund may buy and sell may include futures contracts on fixed-income or other securities, and contracts based on interest rates, foreign currencies or financial indices, including any index of U.S. Government securities. A Fund may, for example, purchase or sell futures contracts and options thereon to hedge against changes in interest rates, securities (through index futures or options) or currencies.

Interest rate futures contracts are purchased or sold for hedging purposes to attempt to protect against the effects of interest rate changes on a Fund’s current or intended investments in fixed-income securities. For example, if a Fund owned long-term bonds and interest rates were expected to increase, that Fund might sell interest rate futures contracts. Such a sale would have much the same effect as selling some of the long-term bonds in that Fund’s portfolio. However, since the futures market is generally more liquid than the cash market, the use of interest rate futures contracts as a hedging technique allows a Fund to hedge its interest rate risk without having to sell its portfolio securities. If interest rates were to increase, the value of the debt securities in the portfolio would decline, but the value of that Fund’s interest rate futures contracts would be expected to increase at approximately the same rate, thereby keeping the NAV of that Fund from declining as much as it otherwise would have. On the other hand, if interest rates were expected to decline, interest rate futures contracts could be purchased to hedge in anticipation of subsequent purchases of long-term bonds at higher prices. Because the fluctuations in the value of the interest rate futures contracts should be similar to those of long-term bonds, a Fund could protect itself against the effects of the anticipated rise in the value of long-term bonds without actually buying them until the necessary cash becomes available or the market has stabilized. At that time, the interest rate futures contracts could be liquidated and that Fund’s cash reserves could then be used to buy long-term bonds on the cash market.

A Fund may purchase and sell foreign currency futures contracts for hedging or risk management purposes in order to protect against fluctuations in currency exchange rates. Such fluctuations could reduce the dollar value of portfolio securities denominated in foreign currencies, or increase the cost of non-U.S. Dollar-denominated securities to be acquired, even if the value of such securities in the currencies in which they are denominated remains constant. A Fund may sell futures contracts on a foreign currency, for example, when it holds securities denominated in such currency and it anticipates a decline in the value of such currency relative to the dollar. If such a decline were to occur, the resulting adverse effect on the value of non-U.S. Dollar-denominated securities may be offset, in whole or in part, by gains on the futures contracts. However, if the value of the foreign currency increases relative to the dollar, a Fund’s loss on the foreign currency futures contract may or may not be offset by an increase in the value

of the securities because a decline in the price of the security stated in terms of the foreign currency may be greater than the increase in value as a result of the change in exchange rates.

Conversely, a Fund could protect against a rise in the dollar cost of non-U.S. Dollar-denominated securities to be acquired by purchasing futures contracts on the relevant currency, which could offset, in whole or in part, the increased cost of such securities resulting from a rise in the dollar value of the underlying currencies. When a Fund purchases futures contracts under such circumstances, however, and the price in dollars of securities to be acquired instead declines as a result of appreciation of the dollar, the Fund will sustain losses on its futures position which could reduce or eliminate the benefits of the reduced cost of portfolio securities to be acquired.

A Fund may also engage in currency “cross hedging” when, in the opinion of the Adviser, the historical relationship among foreign currencies suggests that a Fund may achieve protection against fluctuations in currency exchange rates similar to that described above at a reduced cost through the use of a futures contract relating to a currency other than the U.S. Dollar or the currency in which the foreign security is denominated. Such “cross hedging” is subject to the same risks as those described above with respect to an unanticipated increase or decline in the value of the subject currency relative to the U.S. Dollar.

A Fund may also use foreign currency futures contracts and options on such contracts for non-hedging purposes. Similar to options on currencies described above, a Fund may use foreign currency futures contracts and options on such contracts to seek to increase total return when the Adviser anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund and do not present attractive investment opportunities. The risks associated with foreign currency futures contracts and options on futures contracts are similar to those associated with options on foreign currencies, as described above. For additional information on the use of options on foreign currencies for non-hedging purposes, see “Currency Transactions” below.

Purchases or sales of stock or bond index futures contracts may be for investment purposes. They may also be used for hedging or risk management purposes to attempt to protect a Fund’s current or intended investments from broad fluctuations in stock or bond prices. For example, a Fund may sell stock or bond index futures contracts in anticipation of or during a market decline to attempt to offset the decrease in market value of the Fund’s portfolio securities that might otherwise result. If such decline occurs, the loss in value of portfolio securities may be offset, in whole or in part, by gains on the futures position. When a Fund is not fully invested in the securities market and anticipates a significant market advance, it may purchase stock or bond index futures contracts in order to gain rapid market exposure that may, in whole or in part, offset increases in the cost of securities that the Fund intends to purchase. As such purchases are made, the corresponding positions in stock or bond index futures contracts may be closed out.

Options on futures contracts are options that call for the delivery of futures contracts upon exercise. Options on futures contracts written or purchased by a Fund will be traded on U.S. exchanges.

The writing of a call option on a futures contract constitutes a partial hedge against declining prices of the securities in a Fund’s portfolio. If the futures price at expiration of the

option is below the exercise price, a Fund will retain the full amount of the option premium, which provides a partial hedge against any decline that may have occurred in the Fund’s portfolio holdings. The writing of a put option on a futures contract constitutes a partial hedge against increasing prices of the securities or other instruments required to be delivered under the terms of the futures contract. If the futures price at expiration of the put option is higher than the exercise price, a Fund will retain the full amount of the option premium, which provides a partial hedge against any increase in the price of securities which the Fund intends to purchase. If a put or call option a Fund has written is exercised, the Fund will incur a loss which will be reduced by the amount of the premium it receives. Depending on the degree of correlation between changes in the value of its portfolio securities and changes in the value of its options on futures positions, a Fund’s losses from exercised options on futures may to some extent be reduced or increased by changes in the value of portfolio securities.

A Fund may purchase options on futures contracts for hedging purposes instead of purchasing or selling the underlying futures contracts. For example, where a decrease in the value of portfolio securities is anticipated as a result of a projected market-wide decline or changes in interest or exchange rates, a Fund could, in lieu of selling futures contracts, purchase put options thereon. In the event that such a decrease were to occur, it may be offset, in whole or in part, by a profit on the option. If the anticipated market decline were not to occur, the Fund will suffer a loss equal to the price of the put. Where it is projected that the value of securities to be acquired by a Fund will increase prior to acquisition due to a market advance or changes in interest or exchange rates, a Fund could purchase call options on futures contracts, rather than purchasing the underlying futures contracts. If the market advances, the increased cost of securities to be purchased may be offset by a profit on the call. However, if the market declines, the Fund will suffer a loss equal to the price of the call, but the securities that the Fund intends to purchase may be less expensive.

—Credit Default Swap Agreements. The “buyer” in a credit default swap contract is obligated to pay the “seller” a periodic stream of payments over the term of the contract in return for a contingent payment upon the occurrence of a credit event with respect to an underlying reference obligation. Generally, a credit event means bankruptcy, failure to pay, obligation acceleration or restructuring. A Fund may be either the buyer or seller in the transaction. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between one month and ten years, provided that no credit event occurs. If a credit event occurs, the Fund, as seller, typically must pay the contingent payment to the buyer. The contingent payment will be either (i) the “face amount” of the reference obligation in which case the Fund will receive the reference obligation in return, or (ii) an amount equal to the difference between the face amount and the current market value of the obligation. As a buyer, if a credit event occurs, the Fund would be the receiver of such contingent payments, either delivering the reference obligation in exchange for the full notional (face) value of a reference obligation that may have little or no value, or receiving a payment equal to the difference between the face amount and the current market value of the obligation.

The value of the reference obligation received by the Fund as a seller if a credit event occurs, coupled with the periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the Fund. If the Fund is a buyer and no credit event occurs, the Fund will lose its periodic stream of payments over the term of the

contract. However, if a credit event occurs, the buyer typically receives full notional value for a reference obligation that may have little or no value.

Credit default swaps may involve greater risks than if a Fund had invested in the reference obligation directly. Credit default swaps are subject to general market risk and credit risk, and may be illiquid.

—Currency Swaps. Bond Inflation Strategy and All Market Real Return Portfolio may enter into currency swaps for hedging purposes in an attempt to protect against adverse changes in exchange rates between the U.S. Dollar and other currencies or for non-hedging purposes as a means of making direct investments in foreign currencies, as described below under “Currency Transactions”. Currency swaps involve the exchange by the Fund with another party of a series of payments in specified currencies. Currency swaps may involve the exchange of actual principal amounts of currencies by the counterparties at the initiation, and again upon termination of the transaction. Currency swaps may be bilateral and privately negotiated, with the Fund expecting to achieve an acceptable degree of correlation between its portfolio investments and its currency swaps positions. The Funds will not enter into any currency swap unless the credit quality of the unsecured senior debt or the claims-paying ability of the counterparty thereto is rated in the highest short-term rating category of at least one nationally recognized statistical rating organization (“NRSRO”) at the time of entering into the transaction.

—Swaps: Interest Rate Transactions. A Fund may enter into interest rate swap, swaption and cap or floor transactions, which may include preserving a return or spread on a particular investment or portion of its portfolio or protecting against an increase in the price of securities the Fund anticipates purchasing at a later date. Unless there is a counterparty default, the risk of loss to a Fund from interest rate transactions is limited to the net amount of interest payments that the Fund is contractually obligated to make. If the counterparty to an interest rate transaction defaults, the Fund’s risk of loss consists of the net amount of interest payments that the Fund is contractually entitled to receive.

Interest rate swaps involve the exchange by a Fund with another party of payments calculated by reference to specified interest rates (e.g., an exchange of floating-rate payments for fixed-rate payments) computed based on a contractually-based principal (or “notional”) amount.

An option on a swap agreement, also called a “swaption”, is an option that gives the buyer the right, but not the obligation, to enter into a swap on a future date in exchange for paying a market-based “premium”. A receiver swaption gives the owner the right to receive the total return of a specified asset, reference rate, or index. A payer swaption gives the owner the right to pay the total return of a specified asset, reference rate, or index. Swaptions also include options that allow an existing swap to be terminated or extended by one of the counterparties.

Interest rate caps and floors are similar to options in that the purchase of an interest rate cap or floor entitles the purchaser, to the extent that a specified index exceeds (in the case of a cap) or falls below (in the case of a floor) a predetermined interest rate, to receive payments of interest on a notional amount from the party selling the interest rate cap or floor. It may be more difficult for a Fund to trade or close out interest rate caps and floors in comparison to other types of swaps.

These transactions do not involve the delivery of securities or other underlying assets or principal. A Fund will enter into bilateral swap agreements, including interest rate swap, swaptions, cap or floor transactions but excluding currency swaps, which are subject to separate counterparty requirements as addressed above, only with counterparties who have credit ratings of at least A- (or the equivalent) from any one NRSRO or counterparties with guarantors with debt securities having such a rating. For cleared swaps, the Adviser will monitor the creditworthiness of each of the central clearing counterparty, clearing broker and executing broker but there will be no prescribed NRSRO rating requirements for these entities.

—Inflation (CPI) Swaps. Inflation swap agreements are contracts in which one party agrees to pay the cumulative percentage increase in a price index (the Consumer Price Index with respect to CPI swaps) over the term of the swap (with some lag on the inflation index), and the other pays a compounded fixed rate. Inflation swap agreements may be used to protect the NAV of the Fund against an unexpected change in the rate of inflation measured by an inflation index since the value of these agreements is expected to increase if unexpected inflation increases.

—Total Return Swaps. A Fund may enter into total return swaps in order to take a “long” or “short” position with respect to an underlying referenced asset. The Fund is subject to market price volatility of the underlying referenced asset. A total return swap involves commitments to pay interest in exchange for a market linked return based on a notional amount. To the extent that the total return of the security group of securities or index underlying the transaction exceeds or falls short of the offsetting interest obligation, the Fund will receive a payment or make a payment to the counterparty. Total return swaps may reflect a leveraged investment and incorporate borrowing costs which are borne by the Fund. There is no guarantee that the Fund’s investment via a total return swap will deliver returns in excess of the embedded borrowing costs and, accordingly, the Fund’s performance may be less than would be achieved by a direct investment in the underlying referenced asset.

– Special Risks Associated with Swaps. Risks may arise as a result of the failure of the counterparty to a bilateral swap contract to comply with the terms of the swap contract. The loss incurred by the failure of a counterparty is generally limited to the net interim payment to be received by a Fund, and/or the termination value at the end of the contract. Therefore, the Fund considers the creditworthiness of the counterparty to a bilateral swap contract. The risk is mitigated by having a netting arrangement between the Fund and the counterparty and by the posting of collateral by the counterparty to the Fund to cover the Fund’s exposure to the counterparty.

Additionally, swap values can be highly volatile and expose investors to a high risk of loss. The low initial margin deposits normally required to establish a swap position permit a high degree of leverage. As a result, depending on the type of swap, a relatively small movement in the price of the underlying reference asset or in the market value of the contract may result in a profit or loss which is high in proportion to the amount of funds deposited as initial margin and may result in unquantifiable further loss exceeding any margin deposited. Such risks may arise from unanticipated movements in interest rates or in the value of the underlying securities. The Fund accrues for the changes in value on swap contracts on a daily basis, with the net amount recorded within unrealized appreciation/depreciation of swap contracts on the statement of assets and liabilities. Once the interim payments are settled in cash, the net amount

is recorded as realized gain/(loss) on swaps on the statement of operations, in addition to any realized gain/(loss) recorded upon the termination of swap contracts. Fluctuations in the value of swap contracts are recorded as a component of net change in unrealized appreciation/depreciation of swap contracts on the statement of operations.

Swaps entered into in the OTC market are more likely to be illiquid than exchange-traded instruments as there is no exchange market on which to close out an open OTC swap position. It may therefore be impossible to liquidate an existing position (or to do so at an advantageous price), to assess the value of the position, or to assess the exposure to risk associated with the position.

—Eurodollar Contracts. Eurodollars are time deposits denominated in U.S. dollars and are held at banks outside the U.S., which could be foreign banks or overseas branches of U.S. banks. Eurodollar contracts are U.S. Dollar-denominated futures contracts or options thereon that are tied to a reference rate, such as the Secured Overnight Financing Rate (SOFR), paid on such deposits, and are subject to the same limitations and risks as other futures contracts and options. A Fund may use Eurodollar instruments to hedge against changes in the reference rate. See “LIBOR Replacement Risk” in the Funds’ Prospectus for additional information about those instruments that were tied to the London Interbank Offered Rate (LIBOR).

—Currency Transactions. Bond Inflation Strategy and All Market Real Return Portfolio may invest in non-U.S. Dollar-denominated securities on a currency hedged or un-hedged basis. The Adviser may actively manage a Fund’s currency exposures and may seek investment opportunities by taking long or short positions in currencies through the use of currency-related derivatives, including forward currency exchange contracts, futures contracts and options on futures contracts, swaps and options. The Adviser may enter into transactions for investment opportunities when it anticipates that a foreign currency will appreciate or depreciate in value but securities denominated in that currency are not held by the Fund and do not present attractive investment opportunities. Such transactions may also be used when the Adviser believes that it may be more efficient than a direct investment in a foreign currency-denominated security. A Fund may also conduct currency exchange contracts on a spot basis (i.e., for cash at the spot rate prevailing in the currency exchange market for buying or selling currencies).

Bank Obligations

A Fund may invest in bank obligations, including certificates of deposit, bankers’ acceptances, and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits. The Fund will not invest in fixed time deposits which (1) are not subject to prepayment or (2) provide for withdrawal penalties upon prepayment (other than overnight deposits) if, in the

aggregate, more than 15% of its net assets would be invested in such deposits, repurchase agreements maturing in more than seven days and other illiquid assets.

Obligations of foreign banks involve somewhat different investment risks than those affecting obligations of U.S. banks, including the possibilities that their liquidity could be impaired because of future political and economic developments, that their obligations may be less marketable than comparable obligations of U.S. banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Event-linked Securities

Event-linked securities are variable-rate or fixed-rate fixed-income securities or types of equity securities for which the return of principal and payment of interest are contingent on the severity or non-occurrence of various specified catastrophic events, which may be specific trigger events or a diversified group of events, such as hurricanes, typhoons, wind events or earthquakes. The most common type of fixed-income securities are known as “catastrophe” or “CAT” bonds. In some cases, the trigger event(s) will not be deemed to have occurred unless the event(s) happened in a particular geographic area and was of a certain magnitude (based on independent scientific readings) or caused a certain amount of actual or modeled loss. If the trigger event(s) occurs prior to the securities’ maturity, a Fund may lose all or a portion of its principal and forgo additional interest.

These securities may have a special condition that states that if the issuer (i.e., an insurance or reinsurance company) suffers a loss from a particular pre-defined catastrophe, then the issuer’s obligation to pay interest and/or repay the principal is either deferred or completely forgiven. For example, if a Fund holds a fixed-income security that covers an insurer’s losses due to a hurricane with a “trigger” at $1 billion and a hurricane hits causing $1 billion or more in losses to such insurer, then the Fund will lose all or a portion of its principal invested in the security and forgo any future interest payments. If the trigger event(s) does not occur, the Fund will recover its principal plus interest. Interest typically accrues and is paid on a quarterly basis. Although principal typically is repaid only on the maturity date, it may be repaid in installments, depending on the terms of the securities.

Event-linked securities may be issued by government agencies, insurance companies, reinsurers, special purpose companies or other on-shore or off-shore entities. Event-linked securities are a relatively new type of financial instrument. As a result, there is no significant trading history of these securities and these securities may be illiquid or the markets for these instruments may not be liquid at all times. These securities may be rated, generally below investment grade by a NRSRO or the unrated equivalent, and have the same or equivalent risks as higher yield debt securities (“junk bonds”). The rating primarily reflects the NRSRO’s

calculated probability that a pre-defined trigger event will occur as well as the overall expected loss to the principal of the security.

Forward Commitments and When-Issued and Delayed Delivery Securities

Forward commitments for the purchase or sale of securities may include purchases on a “when-issued” basis or purchases or sales on a “delayed delivery” basis. In some cases, a forward commitment may be conditioned upon the occurrence of a subsequent event, such as approval and consummation of a merger, corporate reorganization or debt restructuring (i.e., a “when, as and if issued” trade). When forward commitment transactions are negotiated, the price is fixed at the time the commitment is made. A Fund assumes the rights and risks of ownership of the security, but the Fund does not pay for the securities until they are received. If a Fund is fully or almost fully invested when forward commitment purchases are outstanding, such purchases may result in a form of leverage. Leveraging the portfolio in this manner may increase the Fund’s volatility of returns.

Forward commitments include “to be announced” (“TBA”) mortgage-backed securities, which are contracts for the purchase or sale of mortgage-backed securities to be delivered at a future agreed-upon date, whereby the specific mortgage pool number or the number of pools that will be delivered to fulfill the trade obligation or terms of the contract are unknown at the time of the trade. Subsequent to the time of the trade, a mortgage pool or pools guaranteed by the Government National Mortgage Association, or GNMA, the Federal National Mortgage Association, or FNMA, or the Federal Home Loan Mortgage Association, or FHLMC (including fixed-rate or variable-rate mortgages) are allocated to the TBA mortgage-backed securities transactions.

At the time a Fund enters into a forward commitment, it will record the transaction and thereafter reflect the value of the security purchased or, if a sale, the proceeds to be received, in determining its NAV. Any unrealized appreciation or depreciation reflected in such valuation of a “when, as and if issued” security would be canceled in the event that the required conditions did not occur and the trade was canceled.

Purchases of securities on a forward commitment or when-issued basis may involve more risk than other types of purchases. For example, by committing to purchase securities in the future, a Fund subjects itself to a risk of loss on such commitments as well as on its portfolio securities. Also, the Fund may have to sell assets which have been set aside in order to meet redemptions. In addition, if a Fund determines it is advisable as a matter of investment strategy to sell the forward commitment or “when-issued” or “delayed delivery” securities before delivery, the Fund may incur a gain or loss because of market fluctuations since the time the commitment to purchase such securities was made. Any such gain or loss would be treated as a capital gain or loss for tax purposes. When the time comes to pay for the securities to be purchased under a forward commitment or on a “when-issued” or “delayed delivery” basis, the Fund will meet its obligations from the then available cash flow or the sale of securities, or, although it would not normally expect to do so, from the sale of the forward commitment or “when-issued” or “delayed delivery” securities themselves (which may have a value greater or less than a Fund’s payment obligation). No interest or dividends accrue to the purchaser prior to the settlement date for securities purchased or sold under a forward commitment. In addition, in

the event the other party to the transaction files for bankruptcy, becomes insolvent, or defaults on its obligation, a Fund may be adversely affected.

Illiquid Securities

A Fund will not invest in illiquid securities if immediately after such investment more than 15% of the Fund’s net assets would be invested in such securities. Under Rule 22e-4 under the 1940 Act, the term illiquid securities means any security or investment that a 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.

Mutual funds do not typically hold a significant amount of restricted securities (securities that are subject to restrictions on resale to the general public) or other illiquid securities because of the potential for delays on resale and uncertainty in valuation. Limitations on resale may have an adverse effect on the marketability of portfolio securities and a mutual fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty satisfying redemptions within seven days. A mutual fund may also have to take certain steps or wait a certain amount of time in order to remove the transfer restrictions for such restricted securities in order to dispose of them, resulting in additional expense and delay.

Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) allows a broader institutional trading market for securities otherwise subject to restriction on resale to the general public. Rule 144A establishes a “safe harbor” from the registration requirements of the Securities Act for resales of certain securities to qualified institutional buyers (“Rule 144A Securities”). An insufficient number of qualified institutional buyers interested in purchasing certain restricted securities held by a Fund, however, could adversely affect the marketability of such portfolio securities and the Fund might be unable to dispose of such securities promptly or at reasonable prices.

The Funds have adopted a liquidity risk management program pursuant to Rule 22e-4 under the 1940 Act and related procedures to categorize each Fund’s investments, including Rule 144A Securities, and identify illiquid investments.

Infrastructure Investments

The All Market Real Return Portfolio may invest in infrastructure-related securities. Infrastructure entities include companies in the infrastructure business and infrastructure projects and assets representing a broad range of businesses, types of projects and assets. The risks that may be applicable to an infrastructure entity vary based on the type of business, project or asset, its location, the developmental stage of a project and an investor’s level of control over the management or operation of the entity.

Infrastructure entities are typically subject to significant government regulations and other regulatory and political risks, including expropriation; political violence or unrest, including war, sabotage or terrorism; and unanticipated regulatory changes by a government or the failure of a government to comply with international treaties and agreements. Additionally,

an infrastructure entity may do business with state-owned suppliers or customers that may be unable or unwilling to fulfill their contractual obligations. Changing public perception and sentiment may also influence a government’s level of support or involvement with an infrastructure entity.

Companies engaged in infrastructure development and construction and infrastructure projects or assets that have not been completed will be subject to construction risks, including construction delays; delays in obtaining permits and regulatory approvals; unforeseen expenses resulting from budget and cost overruns; inexperienced contractors and contractor errors; and problems related to project design and plans. Due to the numerous risks associated with construction and the often incomplete or unreliable data about projected revenues and income for a project, investing in the construction of an infrastructure project involves significant risks. The ability to obtain initial or additional financing for an infrastructure project is often directly tied to its stage of development and the availability of operational data. A project that is complete and operational is more likely to obtain financing than a project at an earlier stage of development. Additionally, an infrastructure entity may not be able to obtain needed additional financing, particularly during periods of turmoil in the capital markets. The cost of compliance with international standards for project finance may increase the cost of obtaining capital or financing for a project. Alternatively, an investment in debt securities of infrastructure entities may also be subject to prepayment risk if lower-cost financing becomes available.

Infrastructure projects or assets may also be subject to operational risks, including the project manager’s ability to manage the project; unexpected maintenance costs; government interference with the operation of an infrastructure project or asset; obsolescence of project; and the early exit of a project’s equity investors. Additionally, the operator of an infrastructure project or asset may not be able pass along the full amount of any cost increases to customers.

An infrastructure entity may be organized under a legal regime that may provide investors with limited recourse against the entity’s assets, the sponsor or other non-project assets and there may be restrictions on the ability to sell or transfer assets. Financing for infrastructure projects and assets is often secured by cash flows, underlying contracts, and project assets. An investor may have limited options and there may be significant costs associated with foreclosing upon any assets that secure repayment of financing.

Insured Bonds

Municipal Bond Inflation Strategy may obtain insurance on its municipal bonds or purchase insured municipal bonds covered by policies issued by monoline insurance companies. Currently, Assured Guaranty Municipal Corp. (“AGM”) is the insurer most actively writing policies on newly issued municipal bonds. AGM (formerly, Financial Security Assurance Holdings Ltd.) is an indirect subsidiary of Assured Guaranty Ltd. (“Assured”). In addition, Build America Mutual Assurance Company (“BAM”) insures newly issued municipal bonds. BAM is a New York domiciled mutual insurance company owned by the issuers of municipal bonds who use BAM to insure their debt obligations. Prior to the 2008 financial crisis, there were several other insurers writing policies on municipal bonds, but the ratings of these insurers have been downgraded (in most cases, severely downgraded) and, while they are still insuring municipal bonds under policies written prior to the financial crisis, they generally are no longer writing new policies. These insurers include National Public Finance Guarantee Corporation (“National”), a wholly-owned subsidiary of MBIA Inc. (“MBIA”); Financial Guaranty Insurance Company

(“FGIC”); Ambac Assurance Corporation (“Ambac”), a wholly-owned subsidiary of Ambac Financial Group, Inc.; ACA Financial Guaranty Corporation (“ACA”); Radian Asset Assurance, Inc. (formerly, Asset Guaranty Insurance Company) (“Radian”), a wholly-owned subsidiary of Radian Group, Inc.; Syncora Guarantee Inc. (“Syncora”) (formerly XL Capital Assurance, Inc.), a wholly-owned subsidiary of Syncora Holdings Ltd. (formerly Security Capital Assurance Ltd.); CIFG Assurance North America, Inc. (formerly, CDC IXIS Financial Guaranty North America, Inc.) (“CIFG NA”); and Berkshire Hathaway Assurance Corporation (“BHAC”), a wholly owned subsidiary of Berkshire Hathaway Inc. As noted above, these insurers have been downgraded and it is possible that additional downgrades may occur. NRSRO ratings reflect the respective NRSRO’s current assessment of the creditworthiness of each insurer and its ability to pay claims on its policies of insurance. Any further explanation as to the significance of the ratings may be obtained only from the applicable NRSRO. The ratings are not recommendations to buy, sell or hold the municipal bonds, and such ratings may be subject to revision or withdrawal at any time by the NRSROs. Any downward revision or withdrawal of either or both ratings may have an adverse effect on the market price of the municipal bonds.

It should be noted that insurance is not a substitute for the basic credit of an issuer, but supplements the existing credit and provides additional security therefor. Moreover, while insurance coverage for the municipal securities held by the Fund may reduce credit risk, it does not protect against market fluctuations caused by changes in interest rates and other factors. As a result of declines in the credit quality and associated downgrades of most municipal bond insurers, insurance has less value than it did in the past. The market now values insured municipal securities primarily based on the credit quality of the issuer of the security with little value given to the insurance feature. In purchasing insured municipal securities, the Adviser currently evaluates the risk and return of such securities through its own research.

Investment in Exchange-Traded Funds and Other Investment Companies

A Fund may invest in shares of exchange-traded funds, or ETFs, including AB ETFs, subject to the restrictions and limitations of the 1940 Act, or any applicable rules, exemptive orders or regulatory guidance. ETFs are pooled investment vehicles that seek to track the performance of a specific index or implement actively-managed investment strategies. Index ETFs will not track their underlying indices precisely since the ETFs have expenses and may need to hold a portion of their assets in cash, unlike the underlying indices, and the ETFs may not invest in all of the securities in the underlying indices in the same proportion as the indices for various reasons. Unlike index ETFs, actively-managed ETFs generally seek to outperform a benchmark index and typically have higher expenses than index ETFs, which expenses reduce investment returns. There are numerous types of index ETFs and actively managed ETFs, including those offering exposure to broad or narrow segments of the equity, fixed income, commodities and foreign currencies markets. A Fund will incur transaction costs when buying and selling ETF shares, and indirectly bear the expenses of the ETFs. In addition, the market value of an ETF’s shares, which is based on supply and demand in the market for the ETF’s shares, may differ from its NAV. Accordingly, there may be times when an ETF’s shares trade at a discount or premium to its NAV.

The Funds may invest, and have invested from time to time, in investment companies other than ETFs, including AB Mutual Funds, as permitted by the 1940 Act or the rules and regulations or exemptive orders thereunder. The Funds intend to invest uninvested cash

balances in an affiliated money market fund as permitted by Rule 12d1-1 under the 1940 Act. As with ETF investments, if a Fund acquires shares in other investment companies, shareholders would bear, indirectly, the expenses of such investment companies (which may include management and advisory fees), which to the extent not waived or reimbursed, would be in addition to that Fund’s expenses. A Fund’s investment in other investment companies, including ETFs, subjects the Fund indirectly to the underlying risks of those investment companies.

To the extent that a Fund is an “acquired fund” for purposes of Rule 12d1-4, the Fund intends to limit its investments in the securities of other investment companies and private funds to no more than 10% of its total assets, subject to certain limited exceptions permitted under the Rule.

Investments in Certain Types of Privately Placed Securities

The Funds may invest in privately placed securities. Privately placed securities in which the Funds invest are typically equity securities of privately held companies that have not been offered to the public and are not publicly traded. Investments in privately placed securities may include venture capital investments, which are investments in new, early or late stage companies and are often funded by, or in connection with, venture capital firms. Investments in securities of privately held companies may present significant opportunities for capital appreciation but involve a high degree of risk that may result in significant decreases in the value of these investments. Privately held companies may not have established products, experienced management or earnings history. The Funds may not be able to sell such investments when the portfolio managers and/or investment personnel deem it appropriate to do so because the securities are not publicly traded. As such, these investments are generally considered to be illiquid until a company’s public offering (which may never occur) and are often subject to additional contractual restrictions on resale following any public offering that may prevent the Funds from selling their shares of these companies for a period of time. Market conditions, developments within a company, investor perception or regulatory decisions may adversely affect a privately held company and delay or prevent a privately held company from ultimately offering its securities to the public. If a Fund invests in privately placed securities, it may incur additional expenses, such as valuation-related expenses, in connection with such investments. Public companies may also issue privately placed securities, which may be illiquid and subject to contractual restrictions on resale.

Investments in the Wholly-Owned Subsidiary

The All Market Real Return Portfolio seeks to gain exposure to commodities and commodity-related investments and derivatives primarily through investments in AllianceBernstein Cayman Inflation Strategy, Ltd., a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). Investments in the Subsidiary are expected to provide the All Market Real Return Portfolio with exposure to the commodity markets within the limitations of Subchapter M of the U.S. Internal Revenue Code of 1986, as amended, and the rules and regulations thereunder (the “Code”) and recent Internal Revenue Service (the “IRS”) revenue rulings, as discussed below under “Dividends, Distributions and Taxes”. The Subsidiary is a company organized under the laws of the Cayman Islands, and is overseen by its own board of directors. The Fund is the sole shareholder of the Subsidiary, and it is not currently expected that shares of the Subsidiary will be sold or offered to other investors.

The Subsidiary is advised by the Adviser, and has the same investment objective and will generally be subject to the same fundamental, non-fundamental and certain other investment restrictions as the Fund; however, the Subsidiary (unlike the Fund), may invest without limitation in commodity-linked swap agreements and other commodity-linked derivative instruments. The Fund and the Subsidiary may test for compliance with certain investment restrictions on a consolidated basis. By investing in the Subsidiary, the Fund is indirectly exposed to the risks associated with the Subsidiary’s investments. The derivatives and other investments held by the Subsidiary are generally similar to those held by the Fund and are subject to the same risks that apply to similar investments if held directly by the Fund.

It is expected that the Subsidiary will invest primarily in commodity-linked derivative instruments, including swap agreements, commodity options, futures contracts and options on futures contracts, backed by a portfolio of inflation-indexed securities and other fixed-income securities. Although the Fund may enter into these commodity-linked derivative instruments directly, the Fund will likely gain exposure to these derivative instruments indirectly by investing in the Subsidiary. To the extent that the Adviser believes that these commodity-linked derivative instruments are better suited to provide exposure to the commodities market than commodity index-linked notes, the Fund’s investment in the Subsidiary will likely increase. The Subsidiary will also invest in inflation-indexed securities and other fixed-income securities, which are intended to serve as margin or collateral for the Subsidiary’s derivatives position. To the extent that the Fund invests in the Subsidiary, the Fund may be subject to the risks associated with those derivative instruments and other securities, which are discussed elsewhere in the Prospectus and this SAI.

While the Subsidiary may be considered similar to an investment company, it is not registered under the 1940 Act and, unless otherwise noted in the Prospectus and this SAI, is not subject to all of the investor protections of the 1940 Act and other U.S. regulations. Changes in the laws of the United States and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in the Prospectus and this SAI and could negatively affect the Fund and its shareholders.

The Fund’s exposure to the commodities markets may subject the Fund to greater volatility than investments in traditional securities. The value of commodity-linked derivative instruments and notes may be affected by changes in overall market movements, commodity index volatility, changes in interest rates, or factors affecting a particular industry or commodity. The Fund may obtain exposure to physical commodities, such as energy, mineral or agricultural products, or intangible commodities, such as emission allowances or carbon credits. Emission allowances are typically issued under a “cap and trade” or “emissions trading” regulation scheme. Under this framework, a limit or “cap” is typically established by a regulator, such as a governmental entity or supranational organization, on the total amount of greenhouse gases that can be emitted by regulated entities. The regulator then issues or sells “emission allowances” or “carbon allowances” to these entities, which may then be bought or sold on the open market. If a cap is decreased, regulated entities are incentivized to further reduce emissions or purchase additional carbon allowances on the open market where prices may be increasing in response to increased demand. Market, regulatory and other developments at the local, regional or national level may adversely affect the value of emission allowances, including due to the revocation of

emission allowances or to changes to or termination of the cap-and-trade program under which emission allowances are traded.

Loans of Portfolio Securities

A Fund may seek to increase income by lending portfolio securities to brokers, dealers and financial institutions (“borrowers”) to the extent permitted under the 1940 Act or the rules or regulations thereunder (as such statutes, rules or regulations may be amended from time to time) or by guidance regarding, interpretations of, or exemptive orders under, the 1940 Act. Under a Fund’s securities lending program, all securities loans will be secured continuously by cash collateral and/or non-cash collateral. Non-cash collateral will include only securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities. Principal risks of lending portfolio securities include that the borrower will fail to return the loaned securities upon termination of the loan and that the value of the collateral will not be sufficient to replace the loaned securities upon the borrower’s default.

In determining whether to lend securities to a particular borrower, the Adviser (subject to oversight by the Board) will consider all relevant facts and circumstances, including the creditworthiness of the borrower. The loans will be made only to borrowers deemed by the Adviser to be creditworthy and when, in the judgment of the Adviser, the consideration that can be earned currently from securities loans of this type justifies the attendant risk. If a loan is collateralized by cash, a Fund will be compensated for the loan from a portion of the net return from the interest earned on cash collateral after a rebate paid to the borrower (in some cases, this rebate may be a “negative rebate”, or fee paid by the borrower to the Fund in connection with the loan). If the Fund receives non-cash collateral, the Fund will receive a fee from the borrower generally equal to a negotiated percentage of the market value of the loaned securities. For its services, the securities lending agent receives a fee from the Fund.

A Fund will have the right to call a loan and obtain the securities loaned at any time on notice to the borrower within the normal and customary settlement time for the securities. While the securities are on loan, the borrower is obligated to pay the Fund amounts equal to any income or other distribution from the securities.

A Fund will invest any cash collateral in shares of a market fund approved by the Board and expected to be managed by the Adviser. Any such investment will be at the Fund’s risk. The Fund may pay reasonable finders’, administrative and custodial fees in connection with a loan.

A Fund will not have the right to vote any securities during the existence of a loan, but will have the right to recall loaned securities in order to exercise voting or other ownership rights. When the Fund lends its securities, its investment performance will continue to reflect changes in the value of securities loaned.

Loan Participations and Assignments

A Fund may invest in direct debt instruments, which are interests in amounts owed to lenders or lending syndicates by corporate, governmental or other borrowers (“Loans”) either by participating as co-lender at the time the Loan is originated (“Participations”) or by buying an interest in the Loan in the secondary market from a financial institution or institutional investor (“Assignments”). A Loan is often administered by a bank or other financial institution that acts as agent for all the holders. The financial status of the agent interposed between a Fund and a borrower may affect the ability of the Fund to receive principal and interest payments.

The success of a Fund’s investment may depend on the skill with which an agent bank administers the terms of the corporate loan agreements, monitors borrower compliance with covenants, collects principal, interest and fee payments from borrowers and, where necessary, enforces creditor remedies against borrowers. Agents typically have broad discretion in enforcing loan agreements.

A Fund’s investment in Participations typically will result in the Fund having a contractual relationship only with the financial institution arranging the Loan with the borrower (the “Lender”) and not with the borrower directly. A Fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the Lender selling the Participation and only upon receipt by the Lender of the payments from the borrower. In connection with purchasing Participations, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the Loan, nor any rights of set-off against the borrower, and the Fund may not directly benefit from any collateral supporting the Loan in which it has purchased the Participation. As a result, the Fund may be subject to the credit risk of both the borrower and the Lender that is selling the Participation. In the event of the insolvency of the Lender selling a Participation, the Fund may be treated as a general creditor of the Lender and may not benefit from any set-off between the Lender and the borrower. Certain Participations may be structured in a manner designed to avoid purchasers of Participations being subject to the credit risk of the Lender with respect to the Participation; but even under such a structure, in the event of the Lender’s insolvency, the Lender’s servicing of the Participation may be delayed and the assignability of the Participation impaired. A Fund will acquire Participations only if the Lender interpositioned between the Fund and the borrower is a Lender having total assets of more than $25 billion and whose senior unsecured debt is rated investment grade by a NRSRO.

When a Fund purchases Assignments from Lenders it will acquire direct rights against the borrower on the Loan. Because Assignments are arranged through private negotiations between potential assignees and potential assignors, however, the rights and obligations acquired by the Fund as the purchaser of an assignment may differ from, and be more limited than, those held by the assigning Lender. The assignability of certain obligations is restricted by the governing documentation as to the nature of the assignee such that the only way in which the Fund may acquire an interest in a Loan is through a Participation and not an Assignment. A Fund may have difficulty disposing of Assignments and Participations because to do so it will have to assign such securities to a third party. Because there is no liquid market for such securities, the Fund anticipates that such securities could be sold only to a limited number of institutional investors. The lack of a liquid secondary market may have an adverse impact on the value of such securities and the Fund’s ability to dispose of particular Assignments or

Participations when necessary to meet the Fund’s liquidity needs in response to a specific economic event such as a deterioration in the creditworthiness of the borrower. The lack of a liquid secondary market for Assignments and Participations also may make it more difficult for the Fund to assign a value to these securities for purposes of valuing the Fund’s portfolio and calculating its asset value.

Loans in which a Fund may invest include participations in “bridge loans”, which are loans taken out by borrowers for a short period (typically less than six months) pending arrangement of more permanent financing through, for example, the issuance of bonds, frequently high-yield bonds issued for the purpose of an acquisition. A Fund may also participate in unfunded loan commitments, which are contractual obligations for future funding, and receive a commitment fee based on the amount of the commitment.

Mortgage-Related Securities, Other Asset-Backed Securities and Structured Securities

The mortgage-related securities in which a Fund may invest typically are securities representing interests in pools of mortgage loans made by lenders such as savings and loan associations, mortgage bankers and commercial banks and are assembled for sale to investors (such as the Fund) by governmental, government-related or private organizations. Private organizations include commercial banks, savings associations, mortgage companies, investment banking firms, finance companies, special purpose finance entities (called special purpose vehicles or SPVs) and other entities that acquire and package loans for resales as mortgage-related securities. Specifically, these securities may include pass-through mortgage-related securities, collateralized mortgage obligations (“CMOs”), CMO residuals, adjustable-rate mortgage securities (“ARMS”), stripped mortgage-backed securities (“SMBSs”), commercial mortgage-backed securities, TBA mortgage-backed securities, mortgage dollar rolls, collateralized obligations and other securities that directly or indirectly represent a participation in or are secured by and payable from mortgage loans on real property and other assets.

Pass-Through Mortgage-Related Securities. Interests in pools of mortgage-related securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment consisting of both interest and principal payments. In effect, these payments are a “pass-through” of the monthly payments made by the individual borrowers on their residential mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying residential property, refinancing or foreclosure, net of fees or costs that may be incurred. Some mortgage-related securities, such as securities issued by GNMA, are described as “modified pass-through”. These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, regardless of whether or not the mortgagor actually makes the payment.

The average life of pass-through pools varies with the maturities of the underlying mortgage instruments. In addition, a pool’s term may be shortened by unscheduled or early payments of principal and interest on the underlying mortgages. The occurrence of mortgage prepayments is affected by factors including the level of interest rates, general economic conditions, the location and age of the mortgage and other social and demographic conditions. As

prepayment rates of individual pools vary widely, it is not possible to accurately predict the average life of a particular pool.

Yields on pass-through securities are typically quoted by investment dealers and vendors based on the maturity of the underlying instruments and the associated average life assumption. In periods of falling interest rates, the rate of prepayment tends to increase, thereby shortening the actual average life of a pool of mortgage-related securities. Conversely, in periods of rising interest rates, the rate of prepayment tends to decrease, thereby lengthening the actual average life of the pool. Actual prepayment experience may cause the yield to differ from the assumed average life yield. Reinvestment of prepayments may occur at higher or lower interest rates than the original investment, thus affecting the yield of the Fund. The compounding effect from reinvestment of monthly payments received by the Fund will increase the yield to shareholders compared with bonds that pay interest semi-annually.

The principal governmental (i.e., backed by the full faith and credit of the U.S. Government) guarantor of mortgage-related securities is GNMA. GNMA is a wholly-owned U.S. Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage bankers) and backed by pools of Federal Housing Administration-insured or U.S. Department of Veterans Affairs-guaranteed mortgages.

Government-related (i.e., not backed by the full faith and credit of the U.S. Government) guarantors include FNMA and FHLMC. FNMA and FHLMC are a government-sponsored corporation or corporate instrumentality of the U.S. Government, respectively (government-sponsored entities or “GSEs”), which were owned entirely by private stockholders until 2008 when they were placed in conservatorship by the U.S. Government in an effort to provide stability in the financial markets and put the GSEs in a sound and solvent condition. After being placed in conservatorship, the GSEs issued senior preferred stock and common stock to the U.S. Treasury in an amount equal to 79.9% of each GSE in return for certain funding and liquidity arrangements. The GSEs continue to operate as going concerns while in conservatorship and each remains liable for all of its obligations associated with its mortgage-backed securities. The U.S. Treasury provided additional funding to the GSEs, but the GSEs have paid dividends to the U.S. Treasury in a cumulative amount that exceeds the payments made to the GSEs by the U.S. Treasury since 2008. The future of the GSEs is unclear as Congress has considered proposals to wind down or restructure the operations of the GSEs. It is uncertain what legislation, if any, may be proposed in the future in Congress or which proposals, if any, might be enacted. The passage of any such proposal has the potential to impact the value of securities issued by a GSE, which could adversely affect the liquidity and value of a Fund’s portfolio. FNMA purchases residential mortgages from a list of approved seller/servicers which include state and federally-chartered savings and loan associations, mutual savings banks, commercial banks and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA. Participation certificates issued by FHLMC, which represent interests in mortgages from FHLMC’s national portfolio, are guaranteed by FHLMC as to the timely payment of interest and ultimate collection of principal.

Commercial banks, savings and loan associations, private mortgage insurance companies, mortgage bankers and other secondary market issuers create pass-through pools of

conventional residential mortgage loans. Securities representing interests in pools created by non-governmental private issuers generally offer a higher rate of interest than securities representing interests in pools created by governmental issuers because there are no direct or indirect governmental guarantees of the underlying mortgage payments. However, private issuers sometimes obtain committed loan facilities, lines of credit, letters of credit, surety bonds or other forms of liquidity and credit enhancement to support the timely payment of interest and principal with respect to their securities if the borrowers on the underlying mortgages fail to make their mortgage payments. The ratings of such non-governmental securities are generally dependent upon the ratings of the providers of such liquidity and credit support and would be adversely affected if the rating of such an enhancer were downgraded.

The structuring of the pass-through pool may also provide credit enhancement. Examples of such credit support arising out of the structure of the transaction include the issue of senior and subordinated securities (e.g., the issuance of securities by a SPV in multiple classes or “tranches”, with one or more classes being senior to other subordinated classes as to payment of principal and interest, with the result that defaults on the underlying mortgage loans are borne first by the holders of the subordinated class); creation of “reserve funds” (in which case cash or investments sometimes funded from a portion of the payments on the underlying mortgage loans, are held in reserve against future losses); and “overcollateralization” (in which case the scheduled payments on, or the principal amount of, the underlying mortgage loans exceeds that required to make payment of the securities and pay any servicing or other fees). There can be no guarantee the credit enhancements, if any, will be sufficient to prevent losses in the event of defaults on the underlying mortgage loans.

In addition, mortgage-related securities that are issued by private issuers are not subject to the underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee. As a result, the mortgage loans underlying private mortgage-related securities may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government-sponsored mortgage-related securities, and have wider variances in a number of terms, including interest rate, term, size, purposes and borrower characteristics. Privately-issued pools more frequently include second mortgages, high loan-to-value mortgages and manufactured housing loans. The coupon rates and maturities of the underlying mortgage loans in a private-label mortgage-related pool may vary to a greater extent than those included in a government guaranteed pool, and the pool may include subprime mortgage loans. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. For these reasons, the loans underlying these securities have had in many cases higher default rates than those loans that meet government underwriting requirements.

Collateralized Mortgage Obligations. Another form of mortgage-related security is a “pay-through” security, which is a debt obligation. A Fund may invest in other forms of mortgage-related securities including CMOs, which are debt obligations of the issuer secured by a pool of mortgage loans pledged as collateral that is legally required to be paid by the issuer, regardless of whether payments are actually made on the underlying mortgages. CMOs are the predominant type of “pay-through” mortgage-related security. In a CMO, a series of bonds or certificates is issued in multiple classes. Each class of a CMO, often referred to as a “tranche”, is issued at a specific coupon rate and has a stated maturity or final distribution date. Principal

prepayments on collateral underlying a CMO may cause one or more tranches of the CMO to be retired substantially earlier than the stated maturities or final distribution dates of the collateral. Although payment of the principal of, and interest on, the underlying collateral securing privately issued CMOs may be guaranteed by GNMA, FNMA or FHLMC, these CMOs represent obligations solely of the private issuer and are not insured or guaranteed by GNMA, FNMA, FHLMC, any other governmental agency or any other person or entity.

Adjustable-Rate Mortgage Securities. Another type of mortgage-related security, known as adjustable-rate mortgage securities (“ARMS”), bears interest at a rate determined by reference to a predetermined interest rate or index. ARMS may be secured by fixed-rate mortgages or adjustable-rate mortgages. ARMS secured by fixed-rate mortgages generally have lifetime caps on the coupon rates of the securities. To the extent that general interest rates increase faster than the interest rates on the ARMS, these ARMS will decline in value. The adjustable-rate mortgages that secure ARMS will frequently have caps that limit the maximum amount by which the interest rate or the monthly principal and interest payments on the mortgages may increase. These payment caps can result in negative amortization (i.e., an increase in the balance of the mortgage loan). Furthermore, since many adjustable-rate mortgages only reset on an annual basis, the values of ARMS tend to fluctuate to the extent that changes in prevailing interest rates are not immediately reflected in the interest rates payable on the underlying adjustable-rate mortgages.

Stripped Mortgage-Related Securities. Stripped mortgage-related securities (“SMRS”) are mortgage-related securities that are usually structured with separate classes of securities collateralized by a pool of mortgages or a pool of mortgage-backed bonds or pass-through securities, with each class receiving different proportions of the principal and interest payments from the underlying assets. A common type of SMRS has one class of interest-only securities (“IOs”) receiving all of the interest payments from the underlying assets and one class of principal-only securities (“POs”) receiving all of the principal payments from the underlying assets. IOs and POs are extremely sensitive to interest rate changes and are more volatile than mortgage-related securities that are not stripped. IOs tend to decrease in value as interest rates decrease and are extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal prepayments may have a material adverse effect on the yield to maturity of the IO class. POs generally increase in value as interest rates decrease. If prepayments of the underlying mortgages are greater than anticipated, the amount of interest earned on the overall pool will decrease due to the decreasing principal balance of the assets. Due to their structure and underlying cash flows, SMRS may be more volatile than mortgage-related securities that are not stripped. Changes in the values of IOs and POs can be substantial and occur quickly, such as occurred in the first half of 1994 when the value of many POs dropped precipitously due to increases in interest rates.

With respect to residential SMRS, a Fund will only invest in such SMRS that are issued by the U.S. Government, its agencies or instrumentalities and supported by the full faith and credit of the United States or by other U.S. Government sponsored entities. Although SMRS are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, the complexity of these instruments and the smaller number of investors in the sector can lend to illiquid markets in the sector.

Commercial Mortgage-Backed Securities. Commercial mortgage-backed securities are securities that represent an interest in, or are secured by, mortgage loans secured by multifamily or commercial properties, such as industrial and warehouse properties, office buildings, retail space and shopping malls, and cooperative apartments, hotels and motels, nursing homes, hospitals and senior living centers. Commercial mortgage-backed securities have been issued in public and private transactions by a variety of public and private issuers using a variety of structures, some of which were developed in the residential mortgage context, including multi-class structures featuring senior and subordinated classes. Commercial mortgage-backed securities may pay fixed or floating-rates of interest. The commercial mortgage loans that underlie commercial mortgage-related securities have certain distinct risk characteristics. Commercial mortgage loans generally lack standardized terms, which may complicate their structure, tend to have shorter maturities than residential mortgage loans and may not be fully amortizing. Commercial properties themselves tend to be unique and are more difficult to value than single-family residential properties. Commercial mortgage-backed securities are subject to heightened risks due to the significant economic impacts of COVID-19 on commercial real estate. In addition, commercial properties, particularly industrial and warehouse properties, are subject to environmental risks and the burdens and costs of compliance with environmental laws and regulations. Global climate change may also have an adverse effect on property and security values.

GSE Risk-Sharing Bonds. Another type of mortgage-related security, known as GSE Risk-Sharing Bonds or Credit Risk Transfer securities ("CRTs"), transfers a portion of the risk of borrower defaults from the issuing GSE to investors through the issuance of a bond whose return of principal is linked to the performance of a selected pool of mortgages. CRTs are issued by GSEs (and sometimes banks or mortgage insurers) and structured without any government or GSE guarantee in respect of borrower defaults or underlying collateral. Typically, CRTs are issued at par and have stated final maturities. CRTs are structured so that: (i) interest is paid directly by the issuing GSE and (ii) principal is paid by the issuing GSE in accordance with the principal payments and default performance of a certain pool of residential mortgage loans acquired by the GSE.

The risks associated with an investment in CRTs differ from the risks associated with an investment in mortgage-backed securities issued by GSEs because, in CRTs, some or all of the credit risk associated with the underlying mortgage loans is transferred to the end-investor. As a result, in the event that a GSE fails to pay principal or interest on a CRT or goes through bankruptcy, insolvency or similar proceeding, holders of such CRT have no direct recourse to the underlying mortgage loans.

Certain Risks. The value of mortgage-related securities is affected by a number of factors. Unlike traditional debt securities, which have fixed maturity dates, mortgage-related securities may be paid earlier than expected as a result of prepayments of underlying mortgages. Such prepayments generally occur during periods of falling mortgage interest rates. If property owners make unscheduled prepayments of their mortgage loans, these prepayments will result in the early payment of the applicable mortgage-related securities. In that event, a Fund may be unable to invest the proceeds from the early payment of the mortgage-related securities in investments that provide as high a yield as the mortgage-related securities. Early payments associated with mortgage-related securities cause these securities to experience significantly greater price and yield volatility than is experienced by traditional fixed-income securities. The

level of general interest rates, general economic conditions and other social and demographic factors affect the occurrence of mortgage prepayments. During periods of falling interest rates, the rate of mortgage prepayments tends to increase, thereby tending to decrease the life of mortgage-related securities. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective life of mortgage-related securities, subjecting them to greater risk of decline in market value in response to rising interest rates. If the life of a mortgage-related security is inaccurately predicted, a Fund may not be able to realize the rate of return it expected.

As with other fixed-income securities, there is also the risk of nonpayment of mortgage-related securities, particularly for those securities that are backed by mortgage pools that contain subprime loans. Market factors adversely affecting mortgage loan repayments include a general economic downturn, high unemployment, a general slowdown in the real estate market, a drop in the market prices of real estate or higher mortgage payments required to be made by holders of adjustable rate mortgages due to scheduled increases or increases due to higher interest rates. To the extent a Fund invests in mortgage-related securities whose underlying mortgages include subprime or non-performing loans, the risk of default is generally greater.

Subordinated mortgage-related securities may have additional risks. The subordinated mortgage-related security may serve as credit support for the senior securities purchased by other investors. In addition, the payments of principal and interest on these subordinated securities generally will be made only after payments are made to the holders of securities senior to the subordinated securities. Therefore, if there are defaults on the underlying mortgage loans, the holders of subordinated mortgage-related securities will be less likely to receive payments of principal and interest and will be more likely to suffer a loss.

Commercial mortgage-related securities, like all fixed-income securities, generally decline in value as interest rates rise. Moreover, although generally the value of fixed-income securities increases during periods of falling interest rates, this inverse relationship is not as marked in the case of single-family residential mortgage-related securities, due to the increased likelihood of prepayments during periods of falling interest rates, and may not be as marked in the case of commercial mortgage-related securities. The process used to rate commercial mortgage-related securities may focus on, among other factors, the structure of the security, the quality and adequacy of collateral and insurance, and the creditworthiness of the originators, servicing companies and providers of credit support.

Although the market for mortgage-related securities is becoming increasingly liquid, those issued by certain private organizations may not be readily marketable. There may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. In particular, the secondary markets for CMOs, IOs and POs may be more volatile than those for other mortgage-related securities, thereby potentially limiting a Fund’s ability to buy or sell those securities at any particular time. Without an active trading market, mortgage-related securities held in a Fund’s portfolio may be particularly difficult to value because of the complexities involved in the value of the underlying mortgages. In addition, the NRSROs may have difficulties in rating commercial mortgage-related securities through different economic cycles and in monitoring such ratings on a longer-term basis.

As with fixed-income securities generally, the value of mortgage-related securities can also be adversely affected by increases in general interest rates relative to the yield provided by such securities. Such an adverse effect is especially possible with fixed-rate mortgage securities. If the yield available on other investments rises above the yield of the fixed-rate mortgage securities as a result of general increases in interest rate levels, the value of the mortgage-related securities will decline.

Other Asset-Backed Securities. A Fund may invest in other asset-backed securities, including interests in pools of lower-rated debt securities and corporate and consumer loans (including non-performing loans), among other things. Like mortgage-backed securities, these securities are pass-through, and the collateral supporting these securities generally is of short maturities.

The securitization techniques used to develop mortgage-related securities are being applied to a broad range of financial assets. Through the use of trusts and special purpose corporations, various types of assets, including automobile loans and leases, credit card receivables, home equity loans, equipment leases and trade receivables, are being securitized in structures similar to the structures used in mortgage securitizations. For example, a Fund may invest in collateralized debt obligations (“CDOs”), which include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust, which is backed by a diversified pool of high-risk, below investment grade fixed-income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade by a NRSRO or equivalent unrated loans. These asset-backed securities are subject to risks associated with changes in interest rates, prepayment of underlying obligations and defaults similar to the risks of investment in mortgage-related securities discussed above.

Each type of asset-backed security also entails unique risks depending on the type of assets involved and the legal structure used. For example, credit card receivables are generally unsecured obligations of the credit card holder and the debtors are entitled to the protection of a number of state and federal consumer credit laws, many of which give such debtors the right to set off certain amounts owed on the credit cards, thereby reducing the balance due. There have also been proposals to cap the interest rate that a credit card issuer may charge. In some transactions, the value of the asset-backed security is dependent on the performance of a third party acting as credit enhancer or servicer. Furthermore, in some transactions (such as those involving the securitization of vehicle loans or leases) it may be administratively burdensome to perfect the interest of the security issuer in the underlying collateral and the underlying collateral may become damaged or stolen.

Structured Securities. A Fund may invest in securities issued in structured financing transactions, which generally involve aggregating types of debt assets in a pool or special purpose entity and then issuing new securities. Types of structured financings include, for example, mortgage-related and other asset-backed securities. A Fund’s investments include investments in structured securities that represent interests in entities organized and operated solely for the purpose of restructuring the investment characteristics of debt obligations. This type of restructuring involves the deposit with or purchase by an entity, such as a corporation or

trust, of specified instruments (such as commercial bank loans) and the issuance by that entity of one or more classes of securities (“Structured Securities”) backed by, or representing interests in, the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued Structured Securities to create securities with different investment characteristics such as varying maturities, payment priorities and interest rate provisions, and the extent of the payments made with respect to Structured Securities is dependent on the extent of the cash flow on the underlying instruments. Because Structured Securities of the type in which the Fund anticipates it will invest typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments.

A Fund is permitted to invest in a class of Structured Securities that is either subordinated or unsubordinated to the right of payment of another class. Subordinated Structured Securities typically have higher yields and present greater risks than unsubordinated Structured Securities.

Under the terms of subordinated securities, payments that would be made to their holders may be required to be made to the holders of more senior securities and/or the subordinated or junior securities may have junior liens, if they have any rights at all, in any collateral (meaning proceeds of the collateral are required to be paid first to holders of more senior securities). As a result, subordinated or junior securities will be disproportionately affected by a default or even a perceived decline in the creditworthiness of the issuer.

Preferred Stock

A Fund may invest in preferred stock. Preferred stock is an equity security that has features of debt because it generally entitles the holder to periodic payments at a fixed rate of return. Preferred stock is subordinated to any debt the issuer has outstanding but has liquidation preference over common stock. Accordingly, preferred stock dividends are not paid until all debt obligations are first met. Preferred stock may be subject to more fluctuations in market value, due to changes in market participants’ perceptions of the issuer’s ability to continue to pay dividends, than debt of the same issuer.

Real Estate Investment Trusts

Real estate investment trusts (“REITs”) are pooled investment vehicles that invest primarily in income-producing real estate or real estate related loans or interests. REITs are generally classified as equity REITs, mortgage REITs or a combination of equity and mortgage REITs. Equity REITs invest the majority of their assets directly in real property and derive income primarily from the collection of rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs invest the majority of their assets in real estate mortgages and derive income from the collection of principal and interest payments. Similar to investment companies, REITs are not taxed on income distributed to shareholders, provided they comply with several requirements of the Code. All Market Real Return Portfolio may invest in REITs and will indirectly bear its proportionate share of expenses incurred by REITs in which it invests in addition to the expenses it incurs directly.

Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. Equity REITs may be affected by changes in the value of the underlying property owned by the REITs, while mortgage REITs may

be affected by the quality of any credit extended. REITs are dependent upon management skills, are not diversified, and are subject to heavy cash flow dependency, default by borrowers and self-liquidation.

Investing in REITs involves risks similar to those associated with investing in small capitalization companies. REITs may have limited financial resources, may trade less frequently and in a limited volume and may be subject to more abrupt or erratic price movements than larger company securities. Historically, small capitalization stocks, such as REITs, have had more price volatility than larger capitalization stocks.

REITs are subject to the possibilities of failing to qualify for tax-free pass-through of income under the Code and failing to maintain their exemptions from registration under the 1940 Act. REITs (especially mortgage REITs) also are subject to interest rate risks. When interest rates decline, the value of a REIT’s investment in fixed-rate obligations can be expected to rise. Conversely, when interest rates rise, the value of a REIT’s investment in fixed-rate obligations can be expected to decline. In contrast, as interest rates on adjustable rate mortgage loans are reset periodically, yields on a REIT’s investments in such loans will gradually align themselves to reflect changes in market interest rates, causing the value of such investments to fluctuate less dramatically in response to interest rate fluctuations than would investments in fixed rate obligations.

Repurchase Agreements and Buy/Sell Back Transactions

A repurchase agreement is an agreement by which a Fund purchases a security and obtains a simultaneous commitment from the seller to repurchase the security at an agreed-upon price and date, normally one day or a week later. The purchase and repurchase obligations are transacted under one document. The resale price is greater than the purchase price, reflecting an agreed-upon “interest rate” that is effective for the period of time the buyer’s money is invested in the security, and which is related to the current market rate of the purchased security rather than its coupon rate. During the term of the repurchase agreement, a Fund monitors on a daily basis the market value of the securities subject to the agreement and, if the market value of the securities falls below the resale amount provided under the repurchase agreement, the seller under the repurchase agreement is required to provide additional securities or cash equal to the amount by which the market value of the securities falls below the resale amount. Because a repurchase agreement permits a Fund to invest temporarily available cash on a fully-collateralized basis, repurchase agreements permit the Fund to earn a return on temporarily available cash while retaining “overnight” flexibility in pursuit of investments of a longer-term nature. Repurchase agreements may exhibit the characteristics of loans by the Fund.

The obligation of the seller under the repurchase agreement is not guaranteed, and there is a risk that the seller may fail to repurchase the underlying security, whether because of the seller’s bankruptcy or otherwise. In such event, a Fund would attempt to exercise its rights with respect to the underlying security, including possible sale of the securities. A Fund may incur various expenses in connection with the exercise of its rights and may be subject to various delays and risks of loss, including (a) possible declines in the value of the underlying securities, (b) possible reduction in levels of income and (c) lack of access to the securities (if they are held through a third-party custodian) and possible inability to enforce the Fund’s rights. The Board has established procedures pursuant to which the Adviser monitors the creditworthiness of the dealers with which a Fund enters into repurchase agreement transactions.

A Fund may enter into buy/sell back transactions, which are similar to repurchase agreements. In this type of transaction, the Fund enters a trade to buy securities at one price and simultaneously enters a trade to sell the same securities at another price on a specified date. Similar to a repurchase agreement, the repurchase price is higher than the sale price and reflects current interest rates. Unlike a repurchase agreement, however, the buy/sell back transaction, though done simultaneously, constitutes two separate legal agreements. A buy/sell back transaction also differs from a repurchase agreement in that the seller is not required to provide margin payments if the value of the securities falls below the repurchase price because the transaction constitutes two separate transactions. A Fund has the risk of changes in the value of the purchased security during the term of the buy/sell back agreement although these agreements typically provide for the repricing of the original transaction at a new market price if the value of the security changes by a specific amount.

Reverse Repurchase Agreements

Reverse repurchase agreements are identical to repurchase agreements, except that rather than buying securities for cash subject to their repurchase by the seller, a Fund sells portfolio assets concurrently with an agreement by the Fund to repurchase the same assets at a later date at a fixed price slightly higher than the sale price. During the reverse repurchase agreement period, the Fund continues to receive principal and interest payments on these securities. Generally, the effect of such a transaction is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while it will be able to keep the interest income associated with those portfolio securities. Such transactions are advantageous only if the “interest cost” to the Fund of the reverse repurchase transaction, i.e., the difference between the sale and repurchase price for the securities, is less than the cost of otherwise obtaining the cash invested in portfolio securities.

Reverse repurchase agreements are considered to be a loan to a Fund by the counterparty, collateralized by the assets subject to repurchase because the incidents of ownership are retained by the Fund. By entering into reverse repurchase agreements, the Fund obtains additional cash to invest in other securities. The Fund may use reverse repurchase agreements for borrowing purposes if it believes that the cost of this form of borrowing will be lower than the cost of bank borrowing. Reverse repurchase agreements create leverage and are speculative transactions because they allow the Fund to achieve a return on a larger capital base relative to its NAV. The use of leverage creates the opportunity for increased income for the Fund’s shareholders when the Fund achieves a higher rate of return on the investment of the reverse repurchase agreement proceeds than it pays in interest on the reverse repurchase transactions. However, there is a risk that returns could be reduced if the rates of interest on the investment proceeds do not exceed the interest paid by the Fund on the reverse repurchase transactions.

Reverse repurchase agreements involve the risk that the market value of the securities the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund’s use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund’s obligation to repurchase the securities. In addition, the use of these investments results

in leveraging the Fund’s common stock because the Fund uses the proceeds to make investments in other securities. See “Borrowings and Use of Leverage” below.

Rights and Warrants

A Fund may invest in rights and warrants which entitle the holder to buy equity securities at a specific price for a specific period of time, but will do so only if the equity securities themselves are deemed appropriate by the Adviser for inclusion in the Fund’s portfolio. Rights and warrants may be considered more speculative than certain other types of investments in that they do not entitle a holder to dividends or voting rights with respect to the securities which may be purchased nor do they represent any rights in the assets of the issuing company. Also, the value of a right or warrant does not necessarily change with the value of the underlying securities, and a right or warrant ceases to have value if it is not exercised prior to the expiration date.

Securities Ratings

The ratings of fixed-income securities by NRSROs such as Moody’s Investors Service, Inc. (“Moody’s”), S&P Global Ratings (“S&P”), Fitch Ratings (“Fitch”), Kroll Bond Rating Agency, LLC (“Kroll”) and DBRS Morningstar are widely accepted barometers of credit risk. They are, however, subject to certain limitations from an investor's standpoint. The rating of an issuer is heavily weighted by past developments and does not necessarily reflect probable future conditions. There is frequently a lag between the time a rating is assigned and the time it is updated. In addition, there may be varying degrees of difference in credit risk of securities within each rating category.

Securities that are rated Ba or lower by Moody’s, BB or lower by S&P or Fitch, or are equivalently rated by other NRSROs are considered to have speculative characteristics. Sustained periods of deteriorating economic conditions or rising interest rates are more likely to lead to a weakening in the issuer’s capacity to pay interest and repay principal than in the case of higher-rated securities.

Non-rated securities will also be considered for investment by a Fund when the Adviser believes that the financial condition of the issuers of such securities, or the protection afforded by the terms of the securities themselves, limits the risk to the Fund to a degree comparable to that of rated securities which are consistent with the Fund’s objectives and policies.

The Adviser generally uses ratings issued by NRSROs such as S&P, Moody’s, Fitch, Kroll and DBRS Morningstar but may rely on ratings from other NRSROs, depending on the security in question. Some securities are rated by more than one NRSRO, and the ratings assigned to the security by the NRSROs may differ. In such an event and for purposes of determining compliance with restrictions on investments for a Fund, if the Adviser considers ratings issued by two or more NRSROs, the Adviser will deem the security to be rated at the highest rating. For example, if a security is rated by Moody’s and S&P only, with Moody’s rating the security as Ba and S&P as BBB, the Adviser will deem the security to be rated as the equivalent of BBB (i.e., Baa by Moody’s and BBB by S&P). Or, if a security is rated by Moody’s, S&P and Fitch, with Moody’s rating the security as Ba, S&P as BBB and Fitch as BB, the Adviser will deem the security to be rated as the equivalent of BBB (i.e., Ba1 by Moody’s, BBB by S&P and BBB by Fitch).

The Adviser will try to reduce the risk inherent in a Fund’s investment approach through credit analysis, diversification and attention to current developments and trends in interest rates and economic conditions. However, there can be no assurance that losses will not occur. In considering investments for Funds, the Adviser will attempt to identify those high-yielding securities whose financial condition is adequate to meet future obligations, has improved or is expected to improve in the future. The Adviser’s analysis focuses on relative values based on such factors as interest or dividend coverage, asset coverage, earnings prospects and the experience and managerial strength of the issuer.

Unless otherwise indicated, references to securities ratings by one NRSRO in this SAI shall include the equivalent rating by another NRSRO.

Short Sales

A Fund may make short sales of securities or maintain a short position. A short sale is effected by selling a security that a Fund does not own, or, if the Fund does own such security, it is not to be delivered upon consummation of sale. A short sale is against the box to the extent that a Fund contemporaneously owns or has the right to obtain securities identical to those sold. A short sale of a security involves the risk that, instead of declining, the price of the security sold short will rise. If the price of the securities sold short increases between the time of a short sale and the time a Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a gain. The potential for the price of a fixed-income security sold short to rise is a function of both the remaining maturity of the obligation, its creditworthiness and its yield. Unlike short sales of equities or other instruments, the potential for the price of a fixed-income security to rise may be limited due to the fact that the security will be no more than par at maturity. However, the short sale of other instruments or securities generally, including fixed-income securities convertible into equities or other instruments, a fixed-income security trading at a deep discount from par or which pays a coupon that is high in relative or absolute terms, or which is denominated in a currency other than the U.S. Dollar, involves the possibility of a theoretically unlimited loss since there is a theoretically unlimited potential for the market price of the security sold short to increase. Short sales may be used in some cases by a Fund to defer the realization of gain or loss for federal income tax purposes on securities then owned by the Fund. See “Dividends, Distributions and Taxes-Tax Straddles” for a discussion of certain special federal income tax considerations that may apply to short sales which are entered into by the Fund.

U.S. Government Securities

U.S. Government securities may be backed by the full faith and credit of the United States, supported only by the right of the issuer to borrow from the U.S. Treasury or backed only by the credit of the issuing agency itself. These securities include: (i) the following U.S. Treasury securities, which are backed by the full faith and credit of the United States and differ only in their interest rates, maturities and times of issuance: U.S. Treasury bills (maturities of one year or less with no interest paid and hence issued at a discount and repaid at full face value upon maturity), U.S. Treasury notes (maturities of one to ten years with interest payable every six months) and U.S. Treasury bonds (generally maturities of greater than ten years with interest payable every six months); (ii) obligations issued or guaranteed by U.S. Government agencies and instrumentalities that are supported by the full faith and credit of the U.S.

Government, such as securities issued by GNMA, the Department of Housing and Urban Development, the Export-Import Bank, the General Services Administration, the Small Business Administration and including obligations that are issued by private issuers that are guaranteed as to principal or interest by the U.S. Government, its agencies or institutions; and (iii) obligations issued or guaranteed by U.S. Government agencies and instrumentalities that were historically not supported by the full faith and credit of the U.S. Government or a right to borrow from the U.S. Treasury, such as securities issued by the FNMA and FHLMC, and governmental CMOs. The maturities of the U.S. Government securities listed in paragraphs (i) and (ii) above usually range from three months to 30 years. Such securities, except GNMA certificates, normally provide for periodic payments of interest in fixed amounts with principal payments at maturity or specified call dates.

U.S. Government securities also include zero-coupon securities and POs and certain SMRS. Zero-coupon securities are described in more detail in “Zero-Coupon Securities” below, and SMRS and POs are described in more detail in “Mortgage-Related Securities, Other Asset-Backed Securities and Structured Securities – Stripped Mortgage-Related Securities” above. In addition, other U.S. Government agencies and instrumentalities have issued stripped securities that are similar to SMRS.

Inflation-indexed securities, such as Treasury Inflation-Protected Securities, or TIPS, are fixed-income securities whose value is periodically adjusted according to the rate of inflation. If the index measuring inflation falls, the principal value of these securities will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-protected securities. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.

Inflation-indexed securities tend to react to changes in real interest rates. In general, the price of these securities can fall when real interest rates rise, and can rise when real interest rates fall. In addition, the value of these securities may be vulnerable to changes in expectations of inflation. Interest payments on these securities can be unpredictable and will vary as the principal and/or interest is adjusted for inflation.

TIPS, which are issued by the U.S Treasury, use the Consumer Price Index for Urban Consumers, or the CPI, as the inflation measure. The principal of a TIPS increases with inflation and decreases with deflation, as measured by the CPI. When a TIPS matures, the holder is paid the adjusted principal or original principal, whichever is greater. TIPS pay interest twice a year, at a fixed rate, which is determined by auction at the time the TIPS are issued. The rate is applied to the adjusted principal; so, like the principal, interest payments rise with inflation and fall with deflation. TIPS are issued in terms of 5, 10 and 20 years.

Guarantees of securities by the U.S. Government or its agencies or instrumentalities guarantee only the payment of principal and interest on the securities, and do not guarantee the securities’ yield or value or the yield or value of the shares of the Fund that holds the securities.

U.S. Government securities are considered among the safest of fixed-income investments. As a result, however, their yields are generally lower than the yields available from other fixed-income securities.

Municipal Securities

Municipal Bond Inflation Strategy invests in municipal securities. Municipal securities include municipal bonds as well as short-term (i.e., maturing in under one year to as much as three years) municipal notes, demand notes and tax-exempt commercial paper. In the event Municipal Bond Inflation Strategy invests in demand notes, the Adviser will continually monitor the ability of the obligor under such notes to meet its obligations. Typically, municipal bonds are issued to obtain funds used to construct a wide range of public facilities, such as schools, hospitals, housing, mass transportation, airports, highways and bridges. The funds may also be used for general operating expenses, refunding of outstanding obligations and loans to other public institutions and facilities.

Municipal bonds have two principal classifications: general obligation bonds and revenue or special obligation bonds. General obligation bonds are secured by the issuer’s pledge of its faith, credit and taxing power for the payment of principal and interest. Revenue or special obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise tax or other specific revenue source but not from general tax and other unrestricted revenues of the issuer. The term “issuer” means the agency, authority, instrumentality or other political subdivision whose assets and revenues are available for the payment of principal of and interest on the bonds. Certain types of private activity bonds are also considered municipal bonds if the interest thereon is exempt from federal income tax.

Private activity bonds are in most cases revenue bonds and do not generally constitute the pledge of the credit or taxing power of the issuer of such bonds. The payment of the principal and interest on such private activity bonds depends solely on the ability of the user of the facilities financed by the bonds to meet its financial obligations and the pledge, if any, of real and personal property so financed as security for such payment.

Municipal Bond Inflation Strategy may also invest in municipal securities of issuers in Puerto Rico or other U.S. territories, which are exempt from federal, state, and, where applicable, local income taxes. These municipal securities may have more risks than those of U.S. issuers generally. Puerto Rico continues to face a very challenging economic and fiscal environment, worsened by the spread of COVID-19 and the adverse effect that related governmental and public responses have had on Puerto Rico’s economy. As a result of Puerto Rico’s challenging economic and fiscal environment, many ratings organizations have downgraded a number of municipal securities issued in Puerto Rico or placed them on a “negative watch”. If the economic situation in Puerto Rico persists or worsens, the volatility and credit quality of Puerto Rican municipal securities could be adversely affected.

Municipal Bond Inflation Strategy may invest a portion of its assets in municipal securities that pay interest at a coupon rate equal to a base rate plus additional interest for a certain period of time if short-term interest rates rise above a predetermined level or “cap”. Although the specific terms of these municipal securities may differ, the amount of any additional interest

payment typically is calculated pursuant to a formula based upon an applicable short-term interest rate index multiplied by a designated factor. The additional interest component of the coupon rate of these municipal securities generally expires before the maturity of the underlying instrument. These municipal securities may also contain provisions that provide for conversion at the option of the issuer to constant interest rates in addition to standard call features.

Municipal Bond Inflation Strategy may invest in zero-coupon securities, which are debt obligations that do not entitle the holder to any periodic payments prior to maturity and are issued and traded at a discount from their face amounts. The discount varies depending on the time remaining until maturity, prevailing interest rates, liquidity of the security and perceived credit quality of the issuer. The market prices of zero-coupon securities are generally more volatile than the market prices of securities that pay interest periodically and are likely to respond to changes in interest rates to a greater degree than do securities having similar maturities and credit quality that do pay periodic interest.

Municipal Bond Inflation Strategy may also invest in municipal securities, the interest rate on which has been divided into two different and variable components, which together result in a fixed interest rate. Typically, the first of the components (the “Auction Component”) pays an interest rate that is reset periodically through an auction process, whereas the second of the components (the “Residual Component”) pays a current residual interest rate based on the difference between the total interest paid by the issuer on the municipal securities and the auction rate paid on the Auction Component. The Fund may purchase both Auction and Residual Components.

Because the interest rate paid to holders of Residual Components is generally determined by subtracting the interest rate paid to the holders of Auction Components from a fixed amount, the interest rate paid to Residual Component holders will decrease the Auction Component’s rate increases and increase as the Auction Component’s rate decreases. Moreover, the extent of the increases and decreases in market value of Residual Components may be larger than comparable changes in the market value of an equal principal amount of a fixed rate municipal security having similar credit quality, redemption provisions and maturity.

Municipal Bond Inflation Strategy may also invest in (i) asset-backed securities, which are securities issued by special purpose entities whose primary assets consist of, for the purposes of the Fund’s investment, a pool of municipal securities, or (ii) partnership and grantor trust-type derivative securities, whose ownership allows the purchaser to receive principal and interest payments on underlying municipal securities. The securities may be in the form of a beneficial interest in a special purpose trust, limited partnership interest or other debt securities issued by a special purpose corporation. Although the securities may have some form of credit or liquidity enhancement, payments on the securities depend predominately upon the municipal securities held by the issuer. There are many types of these securities, including securities in which the tax-exempt interest rate is determined by an index, a swap agreement, or some other formula, for example, the interest rate payable on the security may adjust either at pre-designated periodic intervals or whenever there is a change in the market rate to which the security’s interest rate is tied. Other features may include the right of the Fund to tender the security prior to its stated maturity. The Fund will not purchase an asset-backed or derivatives security unless it has opinion of counsel in connection with the purchase that interest earned by the Fund from the securities is exempt from, as applicable, Federal and state income taxes.

Municipal notes in which the Fund may invest include demand notes, which are tax-exempt obligations that have stated maturities in excess of one year, but permit the holder to sell back the security (at par) to the issuer within 1 to 7 days’ notice. The payment of principal and interest by the issuer of these obligations will ordinarily be guaranteed by letters of credit offered by banks. The interest rate on a demand note may be based upon a known lending rate, such as a bank’s prime rate, and may be adjusted when such rate changes, or the interest rate on a demand note may be a market rate that is adjusted at specified intervals.

Other short-term obligations constituting municipal notes include tax anticipation notes, revenue anticipation notes, bond anticipation notes and tax-exempt commercial paper.

Tax anticipation notes are issued to finance working capital needs of municipalities. Generally, they are issued in anticipation of various seasonal tax revenues, such as ad valorem, income, sales, use and business taxes. Revenue anticipation notes are issued in expectation of receipt of other types of revenues, such as federal revenues available under the Federal Revenue Sharing Programs. Bond anticipation notes are issued to provide interim financing until long-term financing can be arranged. In most such cases, the long-term bonds provide the money for the repayment of the notes.

Tax-exempt commercial paper is a short-term obligation with a stated maturity of 365 days or less (however, issuers typically do not issue such obligations with maturities longer than seven days). Such obligations are issued by state and local municipalities to finance seasonal working capital needs or as short-term financing in anticipation of longer-term financing.

There are, of course, variations in the terms of, and the security underlying, municipal securities, both within a particular rating classification and between such classifications, depending on many factors. The ratings of NRSROs represent their opinions of the quality of the municipal securities rated by them. It should be emphasized that such ratings are general and are not absolute standards of quality. Consequently, municipal securities with the same maturity, coupon and rating may have different yields, while the municipal securities of the same maturity and coupon, but with different ratings, may have the same yield. The Adviser appraises independently the fundamental quality of the securities included in the Fund’s portfolios.

Yields on municipal securities are dependent on a variety of factors, including the general conditions of the municipal securities market, the size of a particular offering, the maturity of the obligation and the rating of the issue. An increase in interest rates generally will reduce the market value of portfolio investments, and a decline in interest rates generally will increase the value of portfolio investments. Municipal securities with longer maturities tend to produce higher yields and are generally subject to greater price movements than obligations with shorter maturities. However, the Fund does not have any restrictions on the maturity of municipal securities in which it may invest. The Fund will seek to invest in municipal securities of such maturities that, in the judgment of the Adviser, will provide a high level of current income consistent with liquidity requirements and market conditions. The achievement of the Fund’s respective investment objectives depends in part on the continuing ability of the issuers of municipal securities in which the Fund invests to meet their obligations for the payment of principal and interest when due. Municipal securities historically have not been subject to

registration with the Commission, although from time to time there have been proposals which would require registration in the future.

After purchase by the Fund, a municipal security may cease to be rated, its rating may be reduced below the minimum required for purchase by the Fund or it may default. These events do not require sales of such securities by the Fund, but the Adviser will consider such event in its determination of whether the Fund should continue to hold the security. To the extent that the ratings given by NRSROs may change as a result of changes in such organizations or their rating systems, the Adviser will attempt to use such changed ratings in a manner consistent with the Fund’s quality criteria as described in the Prospectus.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Code. In addition, the obligations of such issuers may become subject to laws enacted in the future by Congress, state legislatures or referenda extending the time for payment of principal and/or interest, or imposing other constraints upon enforcement of such obligations or upon the ability of municipalities to levy taxes. There is also the possibility that, as a result of litigation or other conditions, the ability of any issuer to pay, when due, the principal or the interest on its municipal bonds may be materially affected.

Proposals have been considered by Congress for the purpose of restricting or eliminating the federal income tax exemption for interest on municipal securities. If such a proposal were enacted, the availability of municipal securities for investment by the Fund and the NAV and yield of the Fund would be affected. Additionally, the Fund’s investment objectives and policies would likely need to be reevaluated.

Standby Commitment Agreements

A Fund may, from time to time, enter into standby commitment agreements. Such agreements commit the Fund, for a stated period of time, to purchase a stated amount of a security that may be issued and sold to the Fund at the option of the issuer. The price and coupon of the security are fixed at the time of the commitment. At the time of entering into the agreement the Fund is paid a commitment fee, regardless of whether or not the security is ultimately issued. A Fund will enter into such agreements only for the purpose of investing in the security underlying the commitment at a yield and price which are considered advantageous to the Fund and which are unavailable on a firm commitment basis.

There can be no assurance that the securities subject to a standby commitment will be issued, and the value of the security, if issued, on the delivery date may be more or less than its purchase price. Since the issuance of the security underlying the commitment is at the option of the issuer, the Fund will bear the risk of capital loss in the event the value of the security declines and may not benefit from an appreciation in the value of the security during the commitment period if the issuer decides not to issue and sell the security to the Fund.

The purchase of a security subject to a standby commitment agreement and the related commitment fee will be recorded on the date on which the security can reasonably be expected to be issued, and the value of the security will thereafter be reflected in the calculation of a Fund’s NAV. The cost basis of the security will be adjusted by the amount of the commitment

fee. In the event the security is not issued, the commitment fee will be recorded as income on the expiration date of the standby commitment.

Structured Products

A Fund may invest in structured products. Structured products, including indexed or structured securities, combine the elements of futures contracts or options with those of debt, preferred equity or a depositary instrument. Generally, the principal amount, amount payable upon maturity or redemption, or interest rate of a structured product is tied (either positively or negatively) to prices, changes in prices, or differences between prices, of underlying assets, such as securities, currencies, intangibles, goods, articles or commodities or by reference to an unrelated benchmark related to an objective index, economic factor or other measure, such as interest rates, currency exchange rates, commodity indices, and securities indices. The interest rate or (unlike most fixed-income securities) the principal amount payable at maturity of a structured product may be increased or decreased depending on changes in the value of the underlying asset or benchmark.

Structured products may take a variety of forms. Most commonly, they are in the form of debt instruments with interest or principal payments or redemption terms determined by reference to the value of a currency or commodity or securities index at a future point in time, but may also be issued as preferred stock with dividend rates determined by reference to the value of a currency or convertible securities with the conversion terms related to a particular commodity.

Investing in structured products may be more efficient and less expensive for a Fund than investing in the underlying assets or benchmarks and the related derivative. These investments can be used as a means of pursuing a variety of investment goals, including currency hedging, duration management and increased total return. In addition, structured products may be a tax-advantaged investment in that they generate income that may be distributed to shareholders as income rather than short-term capital gains that may otherwise result from a derivatives transaction.

Structured products, however, have more risk than traditional types of debt or other securities. These products may not bear interest or pay dividends. The value of a structured product or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. Under certain conditions, the redemption value of a structured product could be zero. Structured products are potentially more volatile and carry greater market risks than traditional debt instruments. The prices of the structured instrument and the benchmark or underlying asset may not move in the same direction or at the same time. Structured products may carry greater trading risk and be more difficult to price than less complex securities or instruments or more traditional debt securities. The risk of these investments can be substantial with the possibility that the entire principal amount is at risk. The purchase of structured products also exposes a Fund to the credit risk of the issuer of the structured product.

Structured Notes and Indexed Securities: A Fund may invest in a particular type of structured instrument sometimes referred to as a “structured note”. The terms of these notes may be structured by the issuer and the purchaser of the note. Structured notes are derivative debt instruments, the interest rate or principal of which is determined by an unrelated indicator (for

example, a currency, security, commodity or index thereof). Indexed securities may include structured notes as well as securities other than debt securities, the interest rate or principal of which is determined by an unrelated indicator. The terms of structured notes and indexed securities may provide that in certain circumstances no principal is due at maturity, which may result in a total loss of invested capital. Structured notes and indexed securities may be positively or negatively indexed, so that appreciation of the unrelated indicator may produce an increase or a decrease in the interest rate or the value of the structured note or indexed security at maturity may be calculated as a specified multiple of the change in the value of the unrelated indicator. Therefore, the value of such notes and securities may be very volatile. Structured notes and indexed securities may entail a greater degree of market risk than other types of debt securities because the investor bears the risk of the unrelated indicator. Structured notes or indexed securities also may be more volatile, carry greater trading risk, and be more difficult to accurately price than less complex securities and instruments or more traditional debt securities.

Commodity Index-Linked Notes and Commodity-Linked Notes: Structured products may provide exposure to the commodities markets. These structured notes may include leveraged or unleveraged commodity index-linked notes, which are derivative debt instruments with principal and/or coupon payments linked to the performance of commodity indices. They also include commodity-linked notes with principal and/or coupon payments linked to the value of particular commodities or commodities futures contracts, or a subset of commodities and commodities future contracts. The value of these notes will rise or fall in response to changes in the underlying commodity, commodity futures contract, subset of commodities or commodities futures contracts or commodity index. These notes expose a Fund economically to movements in commodity prices. These notes also are subject to risks, such as credit, market and interest rate risks, that in general affect the values of debt securities. In addition, these notes are often leveraged, increasing the volatility of each note’s market value relative to changes in the underlying commodity, commodity futures contract or commodity index. Therefore, the Fund might receive interest or principal payments on the note that are determined based upon a specified multiple of the change in value of the underlying commodity, commodity futures contract or index.

Credit-Linked Securities: Credit-linked securities are issued by a limited purpose trust or other vehicle that, in turn, invests in a basket of derivative instruments, such as credit default swaps, interest rate swaps and other securities, in order to provide exposure to certain high-yield or other fixed-income markets. For example, a Fund may invest in credit-linked securities as a cash management tool in order to gain exposure to certain high-yield markets and/or to remain fully invested when more traditional income-producing securities are not available. Like an investment in a bond, investments in credit-linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on the trust’s receipt of payments from, and the trust’s potential obligations to, the counterparties to the derivative instruments and other securities in which the trust invests. For instance, the trust may sell one or more credit default swaps, under which the trust would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the trust would be obligated to pay the counterparty the par value (or other agreed-upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that a Fund would receive as an investor in the trust. A Fund’s

investments in these instruments are indirectly subject to the risks associated with derivative instruments, including, among others, credit risk, default or similar event risk, counterparty risk, interest rate risk, leverage risk and management risk. These securities are generally Rule 144A Securities and therefore may be freely traded among qualified institutional buyers. However, changes in the market for credit-linked securities or the availability of willing buyers may result in reduced liquidity for the securities.

Tender Option Bond Transactions

Municipal Bond Inflation Strategy may enter into, and has, from time to time, entered into tender option bond transactions (“TOBs”) in which the Fund transfers one or more municipal securities into a special purpose entity (the “Trust”). The Fund receives cash and a residual interest security (sometimes referred to as “inverse floaters”) issued by the Trust in return. The Trust simultaneously issues securities, which pay an interest rate that is reset each week based on an index of high-grade short-term demand notes. These securities, sometimes referred to as “floaters”, are bought by third parties, including tax-exempt money market funds, and can be tendered by these holders to a liquidity provider at par, unless certain events occur. The floaters typically have first priority on the cash flow from the underlying municipal securities held by the Trust, and the remaining cash flow, less certain expenses, is paid to holders of the inverse floaters. The interest rate payable on the inverse floaters bears an inverse relationship to the interest rate on the floaters. Under certain circumstances, the Trust may be terminated or collapsed, either by the Fund or upon the occurrence of certain events, such as a downgrade in the credit quality of the underlying municipal securities or in the event holders of the floaters tender their securities to the liquidity provider. The Fund continues to earn all the interest from the transferred municipal securities less the amount of interest paid on the floaters and the expenses of the Trust, which may include payments to the trustee and the liquidity provider and organizational costs. The Fund receives cash proceeds from the Trust’s sale of the floaters as consideration for the transferred municipal securities and uses the cash proceeds for investment purposes (e.g., the purchase of longer-term municipal securities), which involves leverage risk. If multiple Adviser-managed accounts participate in the same Trust, the economic rights and obligations under the residual interest will be shared among the funds ratably in proportion to their participation in the Trust.

Municipal Bond Inflation Strategy, as the holder of the residual inverse floaters, has full exposure to any increase or decrease in the value of the Trust’s underlying municipal securities. Inverse floaters generally will underperform the market of fixed-rate debt securities in a rising interest rate environment (i.e., when bond values are falling), but will tend to outperform the market of fixed-rate debt securities when interest rates decline or remain relatively stable. The price of the inverse floaters will be more volatile than that of the underlying municipal securities because the interest rate is dependent on not only the fixed coupon rate of the underlying municipal securities, but also on the short-term interest rate paid on the floaters. Although volatile in value and return, inverse floaters typically offer the potential for yields higher than those available on fixed-rate debt securities with comparable credit quality, call provisions and maturity.

Service providers are often engaged to assist with establishing, structuring and sponsoring TOB trusts. The service providers, such as administrators, liquidity providers, trustees and remarketing agents, may act at the direction, and as agent, of a fund holding residual interests

in the TOB trust. To the extent a Fund, rather than a third-party bank or financial institution serves as the sponsor of a TOB trust, the Fund’s responsibilities under such an arrangement may give rise to certain risks including compliance, securities laws and operational risks.

For a discussion of the risks of TOBs, see “Borrowings and Use of Leverage”.

Variable, Floating and Inverse Floating Rate Securities

These securities have interest rates that are reset at periodic intervals, usually by reference to some interest rate index or market interest rate. Some of these securities are backed by pools of mortgage loans. Although the rate adjustment feature may act as a buffer to reduce sharp changes in the value of these securities, they are still subject to changes in value based on changes in market interest rates or changes in the issuer’s creditworthiness. Because the interest rate is reset only periodically, changes in the interest rate on these securities may lag behind changes in prevailing market interest rates. Also, some of these securities (or the underlying mortgages) are subject to caps or floors that limit the maximum change in the interest rate during a specified period or over the life of the security.

Zero-Coupon Securities

A zero-coupon security pays no interest to its holder during its life. An investor acquires a zero-coupon security at a discounted price from the face value of the security, which is generally based upon its present value, and which, depending upon the time remaining until maturity, may be significantly less than its face value (sometimes referred to as a “deep discount” price). Upon maturity of the zero-coupon security, the investor receives the face value of the security.

A Fund may invest in zero-coupon Treasury securities, which consist of Treasury bills or the principal components of U.S. Treasury bonds or notes. A Fund may also invest in zero-coupon securities issued by U.S. Government agencies or instrumentalities that are supported by the full faith and credit of the United States, which consist of the principal components of securities of U.S. Government agencies or instrumentalities.

Currently, the only U.S. Treasury security issued without coupons is the Treasury bill. The zero-coupon securities purchased by a Fund may consist of principal components held in STRIPS form issued through the U.S. Treasury’s STRIPS program, which permits the beneficial ownership of the component to be recorded directly in the Treasury book-entry system. In addition, a number of banks and brokerage firms have separated (“stripped”) the principal portion (“corpus”) from the coupon portion of U.S. Treasury bonds and notes and sold them separately in the form of receipts or certificates representing undivided interests in these instruments (which instruments are generally held by a bank in a custodial or trust account).

Because zero-coupon securities trade at a discount from their face or par value but pay no periodic interest, they are subject to greater fluctuations of market value in response to changing interest rates than debt obligations of comparable maturities which make periodic distributions of interest.

Current federal tax law requires that a holder (such as the Funds) of a zero-coupon security accrue a portion of the discount at which the security was purchased as income each year even though the holder receives no interest payment in cash on the security during the year (generally referred to as “original issue discount” or “OID”). As a result, in order to make the distributions necessary for a Fund not to be subject to federal income or excise taxes, the Fund may be required to pay out as an income distribution each year an amount, greater than the total amount of cash that the Fund has actually received as interest during the year, and this distribution of “phantom income” may be taxable to shareholders. A Fund’s obligation to make such distributions could require it to liquidate other investments at times when the Adviser would not otherwise deem it advisable to do so (potentially resulting in taxable gain), or borrow money, and either of these options could reduce fund assets available to purchase other income-producing securities. The Funds believe, however, that it is highly unlikely that it would be necessary to liquidate portfolio securities or borrow money in order to make such required distributions or to meet its investment objective.

Certain Risks and Other Considerations

Borrowings and Use of Leverage. A Fund may use borrowings for investment purposes subject to the restrictions of the 1940 Act. Borrowings by the Fund result in the leveraging of the Fund’s shares of common stock. The proceeds of such borrowings will be invested in accordance with the Fund’s investment objectives and policies. The Fund also may create leverage through the use of derivatives or use leverage for investment purposes by entering into transactions such as reverse repurchase agreements, forward contracts and dollar rolls, and, for Municipal Bond Inflation Strategy, TOBs. This means that the Fund will use the cash proceeds made available during the term of these transactions to make investments in other securities.

Utilization of leverage, which is usually considered speculative, however, involves certain risks to the Fund’s shareholders. These include a higher volatility of the NAV of the Fund’s shares of common stock and the relatively greater effect of changes in the value of the Fund’s portfolio on the NAV of the shares caused by favorable or adverse changes in market conditions or interest rates. So long as the Fund is able to realize a net return on the leveraged portion of its investment portfolio that is higher than the interest expense paid on borrowings or the carrying costs of leveraged transactions, the effect of leverage will be to cause the Fund’s shareholders to realize a higher net return than if the Fund were not leveraged. However, to the extent that the interest expense on borrowings or the carrying costs of leveraged transactions approaches the net return on the leveraged portion of the Fund’s investment portfolio, the benefit of leverage to the Fund’s shareholders will be reduced, and if the interest expense on borrowings or the carrying costs of leveraged transactions were to exceed the net return to shareholders, the Fund’s use of leverage would result in a lower rate of return than if the Fund were not leveraged. Similarly, the effect of leverage in a declining market would normally be a greater decrease in NAV per share than if the Fund were not leveraged. In an extreme case, if the Fund’s current investment income were not sufficient to meet the interest expense on borrowings or the carrying costs of leveraged transactions, it could be necessary for the Fund to liquidate certain of its investments in adverse circumstances, potentially significantly reducing its NAV.

During periods of rising short-term interest rates, the interest paid on floaters in TOBs would increase, which may adversely affect the Municipal Bond Inflation Strategy’s net

return. If rising short-term rates coincide with a period of rising long-term rates, the value of securities with longer-term maturities purchased with the proceeds of leverage would decline, adversely affecting the Fund’s NAV. The value of an inverse floater can be more volatile than the value of other debt securities of comparable maturity and quality. During periods of rising interest rates, the prices of inverse floaters will tend to decline more quickly than those of conventional fixed-rate debt securities. In certain circumstances, adverse changes in interest rates or other events could cause a TOB trust to terminate or collapse, potentially requiring Municipal Bond Inflation Strategy to liquidate the longer-term securities at unfavorable prices to meet the Trust’s outstanding obligations.

Certain transactions, such as derivatives transactions, forward commitments, reverse repurchase agreements and short sales, involve leverage and may expose a Fund to potential losses that, in some cases, may exceed the amount originally invested by the Fund.

Rule 18f-4, among other things, permits a fund to treat reverse repurchase transactions (and other similar financing transactions) either as borrowings (subject to asset coverage requirements under the 1940 Act) or as “derivatives transactions” subject to the risk-based limits of Rule 18f-4.

Management Risk – Quantitative Models. The Adviser may use investment techniques that incorporate, or rely upon, quantitative models. These models may not work as intended and may not enable a Fund to achieve its investment objective. In addition, certain models may be constructed using data from external providers, and these inputs may be incorrect or incomplete, thus potentially limiting the effectiveness of the models. Finally, the Adviser may change, enhance and update its models and its usage of existing models at its discretion.

Investments in Lower-Rated and Unrated Instruments. Bond Inflation Strategy may invest in lower-rated securities, which may include securities having the lowest rating for non-subordinated debt securities by an NRSRO and unrated securities of equivalent investment quality (commonly referred to as “junk bonds”). Debt securities with such a rating are considered by NRSROs to be subject to greater risk of loss of principal and interest than higher-rated securities and are considered to be predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal, which may in any case decline during sustained periods of deteriorating economic conditions or rising interest rates. These securities are considered to have extremely poor prospects of ever attaining any real investment standing, to have a current identifiable vulnerability to default, to be unlikely to have the capacity to pay interest and repay principal when due in the event of adverse business, financial or economic conditions, and/or to be in default or not current in the payment of interest or principal.

Lower-rated securities generally are considered to be subject to greater market risk than higher-rated securities in times of deteriorating economic conditions. In addition, lower-rated securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment-grade securities, although the market values of securities rated below investment grade and comparable unrated securities tend to react less to fluctuations in interest rate levels than do those of higher-rated securities. The market for lower-rated securities may be thinner and less active than that for higher-quality securities, which can adversely affect the prices at which these securities can be sold. To the extent that there is no established secondary market for lower-rated securities, the Adviser may experience difficulty in

valuing such securities and, in turn, the Fund’s assets. In addition, adverse publicity and investor perceptions about lower-rated securities, whether or not based on fundamental analysis, may tend to decrease the market value and liquidity of such lower-rated securities. Transaction costs with respect to lower-rated securities may be higher, and in some cases information may be less available, than is the case with investment-grade securities.

Many fixed-income securities, including certain U.S. corporate fixed-income securities in which the Fund may invest, contain call or buy-back features that permit the issuer of the security to call or repurchase it. Such securities may present risks based on payment expectations. If an issuer exercises such a “call option” and redeems the security, the Fund may have to replace the called security with a lower yielding security, resulting in a decreased rate of return for the Fund.

In seeking to achieve the Fund’s investment objectives, there will be times, such as during periods of rising interest rates, when depreciation and realization of capital losses on securities in the Fund’s portfolio will be unavoidable. Moreover, medium- and lower- rated securities and non-rated securities of comparable quality may be subject to wider fluctuations in yield and market values than higher-rated securities under certain market conditions. Such fluctuations after a security is acquired do not affect the cash income received from that security but are reflected in the NAV of the Fund.

U.S. Corporate Fixed-Income Securities. A Fund may invest in U.S. corporate fixed-income securities that may include securities issued in connection with corporate restructurings such as takeovers or leveraged buyouts, which may pose particular risks. Securities issued to finance corporate restructurings may have special credit risks due to the highly leveraged conditions of the issuer. In addition, such issuers may lose experienced management as a result of the restructuring. Finally, the market price of such securities may be more volatile to the extent that expected benefits from the restructuring do not materialize. A Fund may also invest in U.S. corporate fixed-income securities that are not current in the payment of interest or principal or are in default, so long as the Adviser believes such investment is consistent with the Fund’s investment objectives. A Fund’s rights with respect to defaults on such securities will be subject to applicable U.S. bankruptcy, moratorium and other similar laws.

Risks of Investments in Foreign Securities. Investors should understand and consider carefully the substantial risks involved in securities of foreign companies and governments of foreign nations, some of which are referred to below, and which are in addition to the usual risks inherent in domestic investments. Investing in securities of non-U.S. companies which are generally denominated in foreign currencies, and utilization of derivative investment products denominated in, or the value of which is dependent upon movements in the relative value of, a foreign currency, involve certain considerations comprising both risk and opportunity not typically associated with investing in U.S. companies. These considerations include changes in exchange rates and exchange control regulations, imposition of sanctions or capital controls, political and social instability, expropriation, imposition of foreign taxes, less liquid markets and less available information than are generally the case in the United States, higher transaction costs, less government supervision of exchanges, brokers and issuers, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

There is generally less publicly available information about foreign companies comparable to reports and ratings that are published about companies in the United States. Foreign issuers are subject to accounting and financial standards and requirements that differ, in some cases significantly, from those applicable to U.S. issuers. In particular, the assets and profits appearing on the financial statements of a foreign issuer may not reflect its financial position or results of operations in the way they would be reflected had the financial statement been prepared in accordance with U.S. generally accepted accounting principles. In addition, for an issuer that keeps accounting records in local currency, inflation accounting rules in some of the countries in which Bond Inflation Strategy and All Market Real Return Portfolio will invest require, for both tax and accounting purposes, that certain assets and liabilities be restated on the issuer’s balance sheet in order to express items in terms of currency of constant purchasing power. Inflation accounting may indirectly generate losses or profits. Consequently, financial data may be materially affected by restatements for inflation and may not accurately reflect the real condition of those issuers and securities markets. Substantially less information is publicly available about certain non-U.S. issuers than is available about U.S. issuers.

It is contemplated that foreign securities will be purchased in over-the-counter markets or on stock exchanges located in the countries in which the respective principal offices of the issuers of the various securities are located, if that is the best available market. Foreign securities markets are generally not as developed or efficient as those in the United States and may close for extended periods or for local holidays. While growing in volume, such markets usually have substantially less volume than the United States securities markets, and securities of some foreign companies are more difficult to trade or dispose of and more volatile than securities of comparable United States companies. Similarly, volume and liquidity in most foreign bond markets are less than in the United States and, at times, volatility of price can be greater than in the United States. There is generally less government supervision and regulation of foreign stock exchanges, brokers and listed companies than in the United States.

Expropriation, confiscatory taxation, nationalization, political, economic or social instability or other similar developments, such as military coups and regional and global conflicts, have occurred in the past in countries in which Bond Inflation Strategy and All Market Real Return Portfolio may invest and could adversely affect the Funds’ assets should these conditions or events recur.

The United Kingdom (“U.K.”) formally withdrew from the European Union (“EU”) on January 31, 2020. The U.K. and the EU negotiated an agreement governing their future trading and security relationships. This agreement became effective on a provisional basis on January 1, 2021 and entered into full force on May 1, 2021. The U.K. and the EU also negotiated a Memorandum of Understanding (“MoU”), which creates a framework for voluntary regulatory cooperation in financial services between the U.K. and the EU. The impact on the U.K. and European economies and the broader global economy of the uncertainties associated with implementing the agreement and MoU are significant and could have an adverse effect on the value of a Fund’s investments and its NAV.  These uncertainties include an increase in the regulatory and customs requirements imposed on cross-border trade between the U.K. and the EU, the negotiation and implementation of additional arrangements between the U.K. and the EU affecting important parts of the economy (such as financial services), volatility and illiquidity in markets, currency fluctuations, the renegotiation of other existing trading and cross-border

cooperation arrangements (whether economic, tax, fiscal, legal, regulatory or otherwise) of the U.K. and the EU, and potentially lower growth for companies in the U.K., Europe and globally.

In addition, military conflicts and wars, such as Russia’s large-scale invasion of Ukraine and the war between Israel and Hamas, and responses to such conflicts by governments and intergovernmental organizations have resulted, and may continue to result, in market disruptions in the regions and globally. Future market disruptions are impossible to predict, but could be significant and have a severe adverse effect on the regions and beyond, including significant negative impacts on the economy and the markets for certain securities and commodities, such as oil and natural gas.

Foreign investment in the securities of certain companies in certain countries is restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude Fund investment in certain foreign securities and increase the costs and expenses of Bond Inflation Strategy. Certain countries in which the Fund may invest require governmental approval prior to investments by foreign persons, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries and/or impose additional taxes on foreign investors.

Certain countries may require governmental approval for the repatriation of investment income, capital or the proceeds of sales of securities by foreign investors. In addition, if deterioration occurs in a country’s balance of payments, the country could impose temporary restrictions on foreign capital remittances.

Investing in emerging market securities involves risks different from, and greater than, risks of investing in domestic securities or in the securities of issuers domiciled in developed, foreign countries. These risks include: smaller market capitalization of securities markets, which may suffer periods of relative illiquidity; significant price volatility; restrictions on foreign investment; and the imposition of capital controls, which may restrict the Fund’s ability to repatriate investment income and capital. In addition, foreign investors may be required to register the proceeds of sales and future economic or political crises could lead to price controls, forced mergers, expropriation or confiscatory taxation, seizure, nationalization or creation of government monopolies. The currencies of emerging market countries may experience significant declines against the U.S. Dollar, and devaluation may occur subsequent to investments in these currencies by a Fund. Inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries.

Additional risks of emerging market securities may include: greater social, economic and political uncertainty and instability; more substantial governmental involvement in the economy; less governmental supervision and regulation; unavailability of currency hedging techniques; companies that are newly organized and small; less developed legal systems with fewer security holder rights and practical remedies to pursue claims, including class actions or fraud claims; the limited ability of U.S. authorities to bring and enforce actions against non-U.S. companies and non-U.S. persons; and differences in the nature and quality of financial information, including (i) auditing and financial reporting standards, which may result in unavailability or unreliability of material information about issuers and (ii) the risk that the Public

Company Accounting Oversight Board (“PCAOB”) may not be able to inspect audit practices and work conducted by PCAOB-registered audit firms in certain emerging market countries, such as China. Thus there can be no assurance that the quality of financial reporting or the audits conducted by such audit firms of U.S.-listed emerging market companies meet PCAOB standards. Furthermore, in December 2021, the Commission finalized rules to implement the Holding Foreign Companies Accountable Act, which requires the Commission to prohibit the trading of securities of foreign issuers (including those based in China) on a national securities exchange or through any other method regulated by the Commission (including through “over-the-counter” trading) if the PCAOB is unable to inspect the work papers of the auditors of such companies for three years. To the extent that a Fund invests in the securities of a company whose securities are subject to such a trading prohibition the Fund’s ability to transact in such securities, and the liquidity of the securities, as well as their market price, would likely be adversely affected. Such Fund would also have to seek other markets in which to transact in such securities, which could increase the Fund’s costs. In addition, emerging securities markets may have different clearance and settlement procedures, which may be unable to keep pace with the volume of securities transactions or otherwise make it difficult to engage in such transactions. Settlement problems may cause a Fund to miss attractive investment opportunities, hold a portion of its assets in cash pending investment, or be delayed in disposing of a portfolio security. Such a delay could result in possible liability to a purchaser of the security.

Income from certain investments held by Bond Inflation Strategy and All Market Real Return Portfolio could be reduced by foreign income taxes, including withholding taxes. It is impossible to determine the effective rate of foreign tax in advance. Each Fund’s NAV may also be affected by changes in the rates or methods of taxation applicable to the Fund or to entities in which the Fund has invested. The Adviser can provide no assurance that the tax treatment of investments held by the Fund will not be subject to change. A shareholder otherwise subject to U.S. federal income taxes may, subject to certain limitations, be entitled to claim a credit or deduction for United States federal income tax purposes for his or her proportionate share of such foreign taxes paid by the Fund. See “Foreign Income Taxes” below.

Investors should understand that the expenses of a Fund investing in foreign securities may be higher than those of investment companies investing only in domestic securities since, among other things, the cost of maintaining the custody of foreign securities is higher and purchases and sales of portfolio securities may be subject to higher transaction charges, such as stamp duties and turnover taxes.

For many foreign securities, there are U.S. Dollar-denominated American Depository Receipts (“ADRs”) that are traded in the United States on exchanges or over-the-counter and are issued by domestic banks or trust companies and for which market quotations are readily available. ADRs do not lessen the foreign exchange risk inherent in investing in the securities of foreign issuers. However, by investing in ADRs rather than directly in stock of foreign issuers, a Fund can avoid currency risks which might occur during the settlement period for either purchases or sales. A Fund may purchase foreign securities directly, as well as through ADRs.

Risks of Forward Currency Exchange Contracts, Foreign Currency Futures Contracts and Options thereon, Options on Foreign Currencies and Over-the-Counter Options on Securities. Transactions in forward currency exchange contracts, as well as futures, options on foreign currencies and swaps, are subject to all of the correlation, liquidity and other risks outlined above. In addition, however, such transactions are subject to the risk of governmental actions affecting trading in or the prices of currencies underlying such contracts, which could restrict or eliminate trading and could have a substantial adverse effect on the value of positions held by Bond Inflation Strategy and All Market Real Return Portfolio. In addition, the value of such positions could be adversely affected by a number of other complex political and economic factors applicable to the countries issuing the underlying currencies.

Further, unlike trading in most other types of instruments, there is no systematic reporting of last sale information with respect to the foreign currencies underlying contracts thereon. As a result, the available information on which trading decisions will be based may not be as complete as the comparable data on which Bond Inflation Strategy and All Market Real Return Portfolio make investment and trading decisions in connection with other transactions. Moreover, because the foreign currency market is a global, twenty-four hour market, events could occur in that market but will not be reflected in the forward, futures or options markets until the following day, thereby preventing the Funds from responding to such events in a timely manner.

Settlements of exercises of OTC forward currency exchange contracts or foreign currency options generally must occur within the country issuing the underlying currency, which in turn requires traders to accept or make delivery of such currencies in conformity with any U.S. or foreign restrictions and regulations regarding the maintenance of foreign banking relationships and fees, taxes or other charges.

Unlike transactions entered into by Bond Inflation Strategy and All Market Real Return Portfolio in futures contracts and exchange-traded options, options on foreign currencies, forward currency exchange contracts and OTC options on securities and securities indices may not be traded on contract markets regulated by the CFTC or (with the exception of certain foreign currency options) the Commission. Such instruments may instead be traded through financial institutions acting as market-makers, although foreign currency options are also traded on certain national securities exchanges, such as the Nasdaq PHLX and the Cboe Options Exchange, that are subject to Commission regulation. In an OTC trading environment, many of the protections afforded to exchange participants will not be available. For example, there are no daily price fluctuation limits, and adverse market movements could therefore continue to an unlimited extent over a period of time. Although the purchaser of an option cannot lose more than the amount of the premium plus related transaction costs, this entire amount could be lost. Moreover, the option writer could lose amounts substantially in excess of the initial investment due to the margin and collateral requirements associated with such positions.

In addition, OTC transactions can be entered into only with a financial institution willing to take the opposite side, as principal, of a Fund’s position unless the institution acts as broker and is able to find another counterparty willing to enter into the transaction with the Fund. Where no such counterparty is available, it will not be possible to enter into a desired transaction. There also may be no liquid secondary market in the trading of OTC contracts, and a Fund could be required to retain options purchased or written, or forward currency exchange contracts entered

into, until exercise, expiration or maturity. This in turn could limit the Fund’s ability to profit from open positions or to reduce losses experienced, and could result in greater losses.

Further, OTC transactions are not subject to the guarantee of an exchange clearinghouse, and Bond Inflation Strategy and All Market Real Return Portfolio will therefore be subject to the risk of default by, or the bankruptcy of, the financial institution serving as its counterparty. The Fund will enter into an over-the-counter transaction only with parties whose creditworthiness has been reviewed and found to be satisfactory by the Adviser.

Transactions in OTC options on foreign currencies are subject to a number of conditions regarding the commercial purpose of the purchaser of such option. Bond Inflation Strategy and All Market Real Return Portfolio are not able to determine at this time whether or to what extent additional restrictions on the trading of OTC options on foreign currencies may be imposed at some point in the future, or the effect that any such restrictions may have on the hedging strategies to be implemented by the Fund.

Options on foreign currencies traded on national securities exchanges are within the jurisdiction of the Commission, as are other securities traded on such exchanges. As a result, many of the protections provided to traders on organized exchanges will be available with respect to such transactions. In particular, all foreign currency option positions entered into on a national securities exchange are cleared and guaranteed by the Options Clearing Corporation (“OCC”), thereby reducing the risk of counterparty default. Further, a liquid secondary market in options traded on a national securities exchange may be more readily available than in the OTC market, potentially permitting Bond Inflation Strategy and All Market Real Return Portfolio to liquidate open positions at a profit prior to exercise or expiration, or to limit losses in the event of adverse market movements.

The purchase and sale of exchange-traded foreign currency options, however, is subject to the risks of the availability of a liquid secondary market described above, as well as the risks regarding adverse market movements, the margining of options written, the nature of the foreign currency market, possible intervention by governmental authorities and the effects of other political and economic events. In addition, exchange-traded options on foreign currencies involve certain risks not presented by the OTC market. For example, exercise and settlement of such options must be made exclusively through the OCC, which has established banking relationships in applicable foreign countries for this purpose. As a result, if the OCC determines that foreign governmental restrictions or taxes would prevent the orderly settlement of foreign currency option exercises, or would result in undue burdens on the OCC or its clearing member, the OCC may impose special procedures on exercise and settlement, such as technical changes in the mechanics of delivery of currency, the fixing of dollar settlement prices or prohibitions on exercise.

Options on U.S. Government Securities, futures contracts, options on futures contracts, forward currency exchange contracts and options on foreign currencies may be traded on foreign exchanges. Such transactions are subject to the risk of governmental actions affecting trading in or the prices of foreign currencies or securities. The value of such positions also could be adversely affected by (i) other complex foreign political and economic factors, (ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the Fund’s ability to act upon economic events occurring in foreign markets during nonbusiness hours

in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) lesser trading volume period.

Investments in China. Risks of investments in securities of companies economically tied to China may include the volatility of the Chinese securities markets; the Chinese economy’s heavy dependence on exports, which may decrease, sometimes significantly, when the world economy weakens; the continuing importance of the role of the Chinese Government, which may take legal or regulatory actions that affect the contractual arrangements of a company or economic and market practices, and cause the value of the securities of an issuer held by a Fund to decrease significantly; and political unrest. Such regulatory measures, which may be adopted with little or no warning, can severely restrict a company’s business operations, with potentially dramatic adverse impacts on the market values of its securities. While the Chinese economy has grown rapidly in recent years, the rate of growth has generally been declining, and there can be no assurance that China’s economy will continue to grow in the future. In addition, trade disputes between China and its trading counterparties, including the United States, have arisen and may continue to arise. Such disputes have resulted in trade tariffs and may potentially result in future trade tariffs, as well as embargoes, trade limitations, trade wars and other negative consequences. These consequences could trigger, among other things, a substantial reduction in international trade and adverse effects on, and potential failure of, individual companies and/or large segments of China’s export industry, which could have potentially significant negative effects on the Chinese economy as well as the global economy. U.S. or other sanctions imposed on the Chinese Government or certain Chinese companies may adversely impact the Chinese economy and Chinese issuers in which a Fund invests, and may prohibit or limit the Fund’s ability to invest in securities of certain Chinese issuers or require the Fund’s sale of such securities, potentially on an accelerated schedule or at disadvantageous prices. Risks of investments in companies based in Hong Kong, a special administrative region of China, include heavy reliance on the Chinese economy, plus regional Asian and global economies such as the U.S. economy, which makes these investments vulnerable to changes in these economies, and political unrest. These and related factors may result in adverse effects on investments in China and Hong Kong and have a negative impact on a Fund’s performance. In addition, China’s recent aggression towards Taiwan may impact companies economically tied to Taiwan, including those in supply chain channels.

A Fund may obtain economic exposure to Chinese companies through a special structure known as a variable interest entity (“VIE”), which is designed to provide foreign investors, such as a Fund, with exposure to Chinese companies that operate in certain sectors in which China restricts or prohibits foreign investments. In this structure, the Chinese-based operating company is the VIE and establishes a shell company in a foreign jurisdiction, such as the Cayman Islands. The shell company lists on a non-Chinese exchange (such as the New York Stock Exchange (the “Exchange”) or the Nasdaq Stock Exchange (“NASDAQ”)) and enters into contractual arrangements with the VIE through one or more wholly-owned special purpose vehicles. This structure allows Chinese companies in which the government restricts foreign ownership to raise capital from foreign investors. While the shell company has no equity ownership of the VIE, these contractual arrangements permit the shell company to consolidate the VIE’s financial statements with its own for accounting purposes and provide for economic exposure to the performance of the underlying Chinese operating company. Therefore, an investor in the listed shell company, such as a Fund, will have exposure to the Chinese-based operating company only through contractual arrangements and has no ownership interest in the Chinese-based operating company. The contractual arrangements between the shell company and the VIE

do not provide investors in the shell company with the rights they would have through direct equity ownership, and a foreign investor’s rights may be limited, including by actions of the Chinese government which could determine that the underlying contractual arrangements are invalid. While VIEs are a longstanding industry practice and are well known by Chinese officials and regulators, the structure has not been formally recognized under Chinese law and it is uncertain whether Chinese officials or regulators will withdraw their implicit acceptance of the structure.

It is also uncertain whether the contractual arrangements, which may be subject to conflicts of interest between the legal owners of the VIE and foreign investors, would be enforced by Chinese courts or arbitration bodies. Non-recognition of these structures by the Chinese government, or the inability to enforce such contracts, from which the shell company derives its value, would likely cause the VIE-structured holding(s) to suffer significant and possibly complete and permanent loss, and in turn, adversely affect a Fund’s returns and NAV.

The Fund may invest in renminbi-denominated bonds issued in China (“RMB Bonds”). RMB Bonds, including government and corporate bonds, are available in the China Interbank Bond Market (“CIBM”) to eligible foreign investors through the CIBM Direct Access Program and through the China-Hong Kong Bond Connect program (“Bond Connect”). Both programs are relatively new. Laws, rules, regulations, policies and guidelines relating to each program are untested and subject to change.

The CIBM Direct Access Program, established by the People’s Bank of China, allows eligible foreign institutional investors to conduct trading in the CIBM, subject to other rules and regulations as promulgated by Chinese authorities. Eligible foreign institutional investors who wish to invest directly in the CIBM through the CIBM Direct Access Program may do so through an onshore settlement agent, who would be responsible for making the relevant filings and account opening with the relevant authorities. The Fund is therefore subject to the risk of default or errors on the part of such agent.

Bond Connect provides a channel for overseas investors to invest in the Chinese bond market through investment links between Hong Kong and mainland China. In China, the Hong Kong Monetary Authority Central Money Markets Unit holds Bond Connect securities on behalf of the ultimate investors (such as a Fund) in accounts maintained with a China-based custodian (either the China Central Depository & Clearing Co. or the Shanghai Clearing House). This recordkeeping system subjects a Fund to numerous risks, including the risk that a Fund may have a limited ability to enforce its rights as a bondholder and the risks of settlement delays and counterparty default of the Hong Kong sub-custodian.

Trading through Bond Connect is subject to other restrictions and risks. For example, Bond Connect is generally only available on business days when both the China and Hong Kong markets are open, which may limit a Fund’s ability to trade when it would be otherwise attractive to do so. Investing through Bond Connect also subjects the Fund to the clearance and settlement procedures associated with Bond Connect, which could pose risks to a Fund. Furthermore, securities purchased through Bond Connect generally may not be sold, purchased or otherwise transferred other than through Bond Connect in accordance with applicable rules.

Uncertainties in China’s tax rules related to the taxation of income and gains from investments in Chinese interbank bonds could result in unexpected tax liabilities for a Fund. Investing in the CIMB will also expose the Fund to renminbi currency risks. The ability to hedge renminbi currency risks is limited.  In addition, given the renminbi is subject to exchange control restrictions, a Fund could be adversely affected by delays in converting other currencies into renminbi and vice versa and at times when there are unfavorable market conditions.

Foreign Currency Transactions. Bond Inflation Strategy and All Market Real Return Portfolio may invest, sometimes substantially, in securities denominated in foreign currencies and a corresponding portion of the Funds’ revenues will be received in such currencies. In addition, the Funds may conduct foreign currency transactions for hedging and non-hedging purposes on a spot (i.e., cash) basis or through the use of derivatives transactions, such as forward currency exchange contracts, currency futures and options thereon, and options on currencies as described above. The dollar equivalent of the Funds’ net assets and distributions will be adversely affected by reductions in the value of certain foreign currencies relative to the U.S. Dollar. Such changes will also affect the Funds’ income. The Funds will, however, have the ability to attempt to protect themselves against adverse changes in the values of foreign currencies by engaging in certain of the investment practices listed above. While the Funds have this ability, there is no certainty as to whether, and to what extent, the Funds will engage in these practices.

Currency exchange rates may fluctuate significantly over short periods of time, causing, along with other factors, Funds’ NAV to fluctuate. Currency exchange rates generally are determined by the forces of supply and demand in the foreign exchange markets and the relative merits of investments in different countries, actual or anticipated changes in interest rates and other complex factors, as seen from an international perspective. Currency exchange rates also can be affected unpredictably by the intervention of U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments in the United States or abroad. To the extent the Funds’ total assets adjusted to reflect the Funds’ net position after giving effect to currency transactions are denominated or quoted in the currencies of foreign countries, the Funds will be more susceptible to the risk of adverse economic and political developments within those countries.

Bond Inflation Strategy and All Market Real Return Portfolio will incur costs in connection with conversions between various currencies. The Funds may hold foreign currency received in connection with investments when, in the judgment of the Adviser, it would be beneficial to convert such currency into U.S. Dollars at a later date, based on anticipated changes in the relevant exchange rate. If the value of the foreign currencies in which each Fund receives its income falls relative to the U.S. Dollar between receipt of the income and the making of Fund distributions, the Fund may be required to liquidate securities in order to make distributions if the Fund has insufficient cash in U.S. Dollars to meet distribution requirements.

If the value of the foreign currencies in which Bond Inflation Strategy and All Market Real Return Portfolio receive income falls relative to the U.S. Dollar between receipt of the income and the making of Fund distributions, the Funds may be required to liquidate securities in order to make distributions if the Funds have insufficient cash in U.S. Dollars to meet the distribution requirements that the Funds must satisfy to qualify as a regulated investment company for federal income tax purposes. Similarly, if the value of a particular foreign currency declines between the time the Funds incur expenses in U.S. Dollars and the time cash expenses

are paid, the amount of the currency required to be converted into U.S. Dollars in order to pay expenses in U.S. Dollars could be greater than the equivalent amount of such expenses in the currency at the time they were incurred. In light of these risks, the Funds may engage in certain currency hedging transactions, which themselves, involve certain special risks.

Sovereign Debt Obligations. No established secondary markets may exist for many of the sovereign debt obligations in which a Fund may invest. Reduced secondary market liquidity may have an adverse effect on the market price and a Fund’s ability to dispose of particular instruments when necessary to meet its liquidity requirements or in response to specific economic events such as a deterioration in the creditworthiness of the issuer. Reduced secondary market liquidity for certain sovereign debt obligations may also make it more difficult for a Fund to obtain accurate market quotations for the purpose of valuing its portfolio. Market quotations are generally available on many sovereign debt obligations only from a limited number of dealers and may not represent firm bids of those dealers or prices for actual sales.

By investing in sovereign debt obligations, a Fund will be exposed to the direct or indirect consequences of political, social and economic changes in various countries. Political changes in a country may affect the willingness of a foreign government to make or provide for timely payments of its obligations. The country’s economic status, as reflected, among other things, in its inflation rate, the amount of its external debt and its gross domestic product, will also affect the government’s ability to honor its obligations. In addition, countries that issue debt obligations denominated in a currency other than their local currency, and countries that do not have their own currency (e.g., Eurozone countries) may have a higher risk of default than other countries, because such countries cannot issue local currency to pay such denominated obligations.

Merger, Reorganization, or Liquidation of a Fund. To the extent permitted by law, a Board may determine to merge or reorganize a Fund or a share class, or to close and liquidate a Fund or a share class at any time, which may have adverse consequences for shareholders. In the case of a liquidation, shareholders are expected to receive a liquidating distribution in cash or in-kind equal to their proportionate interest in the Fund or the class, as applicable. In the event the Board determines to liquidate a Fund or a share class, the timing of the liquidation might not be the most favorable to certain shareholders. A liquidating distribution may be a taxable event to certain shareholders, resulting in a taxable gain or loss for tax purposes, depending upon a shareholder’s basis in the shareholder’s shares of the Fund. A shareholder may receive an amount in liquidation less than the shareholder’s original investment.

Fundamental Investment Policies

Each Fund has adopted the following fundamental investment policies, which may not be changed without approval by the vote of a majority of a Fund’s outstanding voting securities, which means the affirmative vote of the holders of (i) 67% or more of the shares of the Fund represented at a meeting at which more than 50% of the outstanding shares are present in

person or by proxy, or (ii) more than 50% of the outstanding shares of the Fund, whichever is less.

As a matter of fundamental policy, a Fund:

(a)       may not concentrate investments in an industry, as concentration may be defined under the 1940 Act or the rules and regulations thereunder (as such statute, rules or regulations may be amended from time to time) or by guidance regarding, interpretations of, or exemptive orders under, the 1940 Act or the rules or regulations thereunder published by appropriate regulatory authorities;

(b)       may not issue any senior security (as that term is defined in the 1940 Act) or borrow money, except to the extent permitted by the 1940 Act or the rules and regulations thereunder (as such statute, rules or regulations may be amended from time to time) or by guidance regarding, or interpretations of, or exemptive orders under, the 1940 Act or the rules or regulations thereunder published by appropriate regulatory authorities. For purposes of this restriction, margin and collateral arrangements, including, for example, with respect to permitted borrowings, options, futures contracts, options on futures contracts and other derivatives such as swaps are not deemed to involve the issuance of a senior security;

(c)       may not make loans except through (i) the purchase of debt obligations in accordance with its investment objective and policies; (ii) the lending of portfolio securities; (iii) the use of repurchase agreements; or (iv) the making of loans to affiliated funds as permitted under the 1940 Act, the rules and regulations thereunder (as such statutes, rules or regulations may be amended from time to time), or by guidance regarding, and interpretations of, or exemptive orders under, the 1940 Act;

(d)       may not purchase or sell real estate except that it may dispose of real estate acquired as a result of the ownership of securities or other instruments. This restriction does not prohibit the Fund from investing in securities or other instruments backed by real estate or in securities of companies engaged in the real estate business;

(e)       with respect to Bond Inflation Strategy and Municipal Bond Inflation Strategy, may purchase or sell commodities or options thereon to the extent permitted by applicable law and, with respect to All Market Real Return Portfolio, may not purchase or sell commodities except to the extent that the Fund may do so in accordance with applicable law and the Fund’s Prospectus and SAI, as they may be amended from time to time, and without registering as a commodity pool operator under the Commodity Exchange Act; or

(f)       may not act as an underwriter of securities, except that the Fund may acquire restricted securities under circumstances in which, if such securities were sold, the Fund might be deemed to be an underwriter for purposes of the Securities Act.

As a fundamental policy, which cannot be changed without shareholder approval, each Fund is diversified (as that term is defined in the 1940 Act). This means that at least 75% of the Fund’s assets consist of:

Non-Fundamental Investment Policies

The following are descriptions of operating policies that the Funds have adopted but that are not fundamental and are subject to change without shareholder approval.

The Funds may not purchase securities on margin, except (i) as otherwise provided under rules adopted by the Commission under the 1940 Act or by guidance regarding the 1940 Act, or interpretations thereof, and (ii) that the Funds may obtain such short-term credits as are necessary for the clearance of portfolio transactions, and the Funds may make margin payments in connection with futures contracts, options, forward contracts, swaps, caps, floors, collars and other financial instruments.

The Adviser

The Adviser, a Delaware limited partnership with principal offices at 501 Commerce Street, Nashville, TN 37203, has been retained under an investment advisory agreement (the “Advisory Agreement”) to provide investment advice and, in general, to conduct the management and investment program of each Fund under the supervision of the Board (see “Management of the Funds” in the Prospectus). The Adviser is an investment adviser registered under the Investment Advisers Act of 1940, as amended.

The Adviser is a leading global investment management firm supervising client accounts with assets as of September 30, 2023, totaling approximately $669 billion. The Adviser provides management services for many of the largest U.S. public and private employee benefit plans, endowments, foundations, public employee retirement funds, banks, insurance companies and high net worth individuals worldwide.

As of September 30, 2023, the ownership structure of the Adviser, expressed as a percentage of general and limited partnership interests, was as follows:

Equitable Holdings, Inc. (formerly named AXA Equitable Holdings, Inc.) (“EQH”) is a leading financial services company in the U.S. and consists of two well-established principal franchises, Equitable Financial Life Insurance Company and AllianceBernstein.

As of September 30, 2023, EQH owned approximately 3.6% of the issued and outstanding units representing assignments of beneficial ownership of limited partnership interests in AllianceBernstein Holding L.P. (“AB Holding”). AllianceBernstein Corporation (an indirect wholly-owned subsidiary of EQH, “GP”) is the general partner of both AB Holding and the Adviser. The GP owns 100,000 general partnership units in AB Holding and a 1% general partnership interest in the Adviser.

Including both the general partnership and limited partnership interests in AB Holding and the Adviser, EQH and its subsidiaries have an approximate 61.7% economic interest in the Adviser as of September 30, 2023.

During the second quarter of 2018, AXA S.A. (“AXA”), a French holding company for the AXA Group, completed the sale of a minority stake in EQH through an initial public offering. Since the initial sale, AXA has completed additional offerings (and related transactions). As a result, as of May 20, 2021, AXA no longer owns shares of EQH.

Sales that were completed on November 13, 2019 resulted in the indirect transfer of a “controlling block” of voting securities of the Adviser (a “Change of Control Event”) and may have been deemed to have been an “assignment” causing a termination of the Funds’ investment advisory agreements. In order to ensure that investment advisory services could continue uninterrupted in the event of a Change of Control Event, the Board previously approved new investment advisory agreements with the Adviser, and shareholders of the Funds subsequently approved the new investment advisory agreements. These agreements became effective on November 13, 2019.

Advisory Agreements and Expenses

Under the Funds’ Advisory Agreement, the Adviser serves as investment manager and adviser of each of the Funds, continuously furnishes an investment program for each Fund, and manages, supervises and conducts the affairs of each Fund, subject to oversight of the Board. The Adviser also provides persons satisfactory to the Board to act as officers of the Funds. Such officers or employees may be employees of the Adviser or of its affiliates.

The Adviser is, under the Funds’ Advisory Agreement, responsible for any expenses incurred by a Fund in promoting the sale of Fund shares (other than the portion of the promotional expenses borne by the Fund in accordance with an effective plan pursuant to Rule 12b-1 under the 1940 Act, and the costs of printing and mailing Fund prospectuses and other reports to shareholders and all expenses and fees related to proxy solicitations and registrations and filings with the Commission and with state regulatory authorities).

Each Fund has, under the Advisory Agreement, assumed the obligation for payment of all of its other expenses. As to the obtaining of services other than those specifically provided to the Funds by the Adviser, each Fund may employ its own personnel. The Advisory Agreement provides for reimbursement to the Adviser of the costs of certain non-advisory services provided to a Fund. Costs currently reimbursed include the costs of the Adviser’s personnel performing certain administrative services for the Funds, including clerical, accounting, legal and other services (“administrative services”), and associated overhead costs, such as office space, supplies and information technology. The administrative services are provided to the Funds on a fully-costed basis (i.e., includes each person’s total compensation and a factor reflecting the Adviser’s total cost relating to that person, including all related overhead expenses). The reimbursement of these costs to the Adviser will be specifically approved by the Board. For

the fiscal year ended October 31, 2023, Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio paid the Adviser in respect of such services $101,582, $85,966 and $85,046, respectively.

The Advisory Agreement continues in effect with respect to each Fund so long as such continuance is specifically approved at least annually by the Company’s Directors or by a majority vote of the holders of the outstanding voting securities of each Fund and, in either case, by a majority of the Directors who are not parties to the Advisory Agreement, or interested persons of any such party, at a meeting called for the purpose of voting on such matter. Most recently, continuance of the Advisory Agreement for an additional annual term was approved by vote by the Board, at their meetings held on October 31-November 2, 2023 for All Market Real Return Portfolio and August 1-2, 2023 for Bond Inflation Strategy and Municipal Bond Inflation Strategy.

Any material amendment to the Advisory Agreement must be approved by the vote of a majority of the outstanding voting securities of the relevant Fund and by the vote of a majority of the Directors who are not interested persons of the Fund or the Adviser. The Advisory Agreements may be terminated without penalty by the Adviser, by vote of the Directors or by vote of a majority of the outstanding voting securities of the relevant Fund upon 60 days’ written notice, and it terminates automatically in the event of its assignment. The Advisory Agreement provides that in the absence of willful misfeasance, bad faith or gross negligence on the part of the Adviser, or of reckless disregard of its obligations thereunder, the Adviser shall not be liable for any action or failure to act in accordance with its duties thereunder.

In addition, to the extent that a Fund invests in AB Government Money Market Portfolio (except for the investment of any cash collateral from securities lending), the Adviser has contractually agreed to waive its management fee from the Fund and/or reimburse other expenses of the Fund in an amount equal to the Fund’s pro rata share of the AB Government Money Market Portfolio’s effective management fee. This agreement will remain in effect until January 31, 2025 and may only be terminated or changed with the consent of the Fund’s Directors. In addition, the agreement will be automatically extended for one-year terms unless the Adviser provides notice of termination to the Fund at least 60 days prior to the end of the period from the effective date of the registration statement of that Fund to the effective date of the subsequent registration statement of that Fund incorporating the Fund’s annual financial statements (the “Period”). To the extent that a Fund invests securities lending cash collateral in the AB Government Money Market Portfolio, the Adviser has also agreed to waive a portion of the Fund’s share of the advisory fees of AB Government Money Market Portfolio.

Bond Inflation Strategy has contractually agreed to pay a monthly fee to the Adviser at an annualized rate of .50 of 1% of the first $2.5 billion, .45 of 1% of the excess over $2.5 billion up to $5 billion and .40 of 1% of the excess over $5 billion of the Fund’s average net assets. The Adviser has contractually agreed for the Period to waive its fee and bear certain expenses so that total operating expenses, excluding interest expense, do not, on an annual basis, exceed .75%, 1.50%, .50%, 1.00%, .75%, .50%, .50% .60% and .50% for Class A, Class C, Advisor Class, Class R, Class K, Class I, Class Z, Class 1 and Class 2 shares, respectively. This fee waiver and/or expense reimbursement agreement may only be terminated or changed with the consent of the Fund’s Directors and automatically extends each year unless the Adviser provides notice 60 days prior to the end of the Period. For the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the Adviser received under the Advisory Agreement the amount of $4,316,625, $5,874,855 and $3,659,031, respectively, as advisory fees from the Fund.

This fee waiver and/or expense reimbursement agreement may only be terminated or changed with the consent of the Fund’s Directors and automatically extends each year unless the Adviser provides notice 60 days prior to the end of the Period. For the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the Adviser received under the Advisory Agreement the amount of $9,502,330, $12,444,644 and $6,726,535, respectively, as advisory fees from the Fund. Under the expense limitation undertaking, $1,424,418, $1,604,631 and $980,227 was waived and/or reimbursed by the Adviser for the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, respectively. In connection with the investment by the Fund in the AB Government Money Market Portfolio, the Adviser waived its investment management fee from the Fund in the amount of $12,701, $71,896 and $33,266, respectively, for the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021.

This fee waiver and/or expense reimbursement agreement may only be terminated or changed with the consent of the Fund’s Directors and automatically extends each year unless the Adviser provides notice 60 days prior to the end of the Period. For the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the Adviser received under the Advisory Agreement the amount of $7,114,140, $9,235,305 and $8,828,846, respectively, as advisory fees from the Fund. Under the expense limitation undertaking, $45, $29 and $23,383 was waived and/or reimbursed by the Adviser for the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, respectively. In connection with the investment by the Fund in the AB Government Money Market Portfolio, the Adviser waived its investment management fee from the Fund in the amount of $293,946, $214,886 and $139,397, respectively, for the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021.

Board of Directors Information

Certain information concerning the Directors and the Advisory Board member is set forth below.

______________

The business and affairs of the Company are overseen by the Board. The Board has also established an Advisory Board, whose member assists the Board in a non-voting capacity in its oversight of the management of the Company. The Board remains solely responsible for the oversight of management of the Fund. Directors who are not “interested persons” of the Company, as defined in the 1940 Act, are referred to as “Independent Directors”, and Directors

who are “interested persons” of the Company are referred to as “Interested Directors”. Certain information concerning the Company’s governance structure and each Director is set forth below.

Experience, Skills, Attributes, and Qualifications of the Company’s Directors. The Governance and Nominating Committee of the Board, which is composed of Independent Directors, reviews the experience, qualifications, attributes and skills of potential candidates for nomination or election by the Board, and conducts a similar review in connection with the proposed nomination of current Directors for re-election by shareholders at any annual or special meeting of shareholders. In evaluating a candidate for nomination or election as a Director, the Governance and Nominating Committee considers the contribution that the candidate would be expected to make to the diverse mix of experience, qualifications, attributes and skills that the Board believes contributes to good governance for the Fund. In assessing diversity of experience, the Governance and Nominating Committee takes account of a candidate’s educational and professional background, but also the diversity of experience a candidate derives from race, gender, ethnicity, religion, nationality, disability, sexual orientation, or cultural background. Additional information concerning the Governance and Nominating Committee’s consideration of nominees appears in the description of the Committee below.

The Board believes that, collectively, the Directors have balanced and diverse experience, qualifications, attributes and skills, which allow the Board to operate effectively in governing the Company and protecting the interests of shareholders. The Board has concluded that, based on each Director’s experience, qualifications, attributes or skills on an individual basis and in combination with those of the other Directors, each Director is qualified and should continue to serve as such.

In determining that a particular Director was and continues to be qualified to serve as a Director, the Board has considered a variety of criteria, none of which, in isolation, was controlling. In addition, the Board has taken into account the actual service and commitment of each Director during his or her tenure (including the Director’s commitment and participation in Board and committee meetings, as well as his or her current and prior leadership of standing and ad hoc committees) in concluding that each should continue to serve. Additional information about the specific experience, skills, attributes and qualifications of each Director, which in each case led to the Board’s conclusion that the Director should serve (or continue to serve) as trustee or director of the Fund, is provided in the table above and in the next paragraph.

attributes and skills does not impose on such member any duties, obligations or liability that are greater than the duties, obligations and liability imposed on such member as a member of the Advisory Board in the absence of such experience, qualifications, attributes and skills.

Board Structure and Oversight Function. The Board is responsible for oversight of the management of the Company. The Company has engaged the Adviser to manage the Fund on a day-to-day basis. The Board is responsible for overseeing the Adviser and the Company’s other service providers in the operations of the Company in accordance with the Company’s investment objective and policies and otherwise in accordance with its prospectus, the requirements of the 1940 Act and other applicable Federal, state and other securities and other laws, and the Company’s charter and bylaws. The Board typically meets at regularly scheduled meetings four times throughout the year. In addition, the Directors may meet at special meetings or on an informal basis at other times. The Independent Directors also regularly meet without the presence of any representatives of management. As described below, the Board has established three standing committees – the Audit, Governance and Nominating, and Independent Directors Committees – and may establish ad hoc committees or working groups from time to time, to assist the Board in fulfilling its oversight responsibilities. Each committee is composed exclusively of Independent Directors. The responsibilities of each committee, including its oversight responsibilities, are described further below. The Independent Directors have also engaged independent legal counsel, and may, from time to time, engage consultants and other advisors, to assist them in performing their oversight responsibilities.

An Independent Director serves as Chairman of the Board. The Chairman’s duties include setting the agenda for each Board meeting in consultation with management, presiding at each Board meeting, meeting with management between Board meetings and facilitating communication and coordination between the Independent Directors and management. The Directors have determined that the Board’s leadership by an Independent Director and its committees composed exclusively of Independent Directors is appropriate because they believe it sets the proper tone to the relationships between the Fund, on the one hand, and the Adviser and other service providers, on the other, and facilitates the exercise of the Board’s independent judgment in evaluating and managing the relationships. In addition, the Company is required to have an Independent Director as Chairman pursuant to certain 2003 regulatory settlements involving the Adviser.

Risk Oversight. The Company is subject to a number of risks, including investment, compliance and operational risks, including cyber risks. Day-to-day risk management with respect to the Company resides with the Adviser or other service providers (depending on the nature of the risk), subject to supervision by the Adviser. The Board has charged the Adviser and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrable and material adverse effects on the Fund; (ii) to the extent appropriate, reasonable or practicable, implementing processes and controls reasonably designed to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously, and to revise as appropriate, the processes and controls described in (i) and (ii) above.

Risk oversight forms part of the Board’s general oversight of the Company’s investment program and operations and is addressed as part of various regular Board and

committee activities. The Company’s investment management and business affairs are carried out by or through the Adviser and other service providers. Each of these persons has an independent interest in risk management but the policies and the methods by which one or more risk management functions are carried out may differ from the Company’s and each other’s in the setting of priorities, the resources available or the effectiveness of relevant controls. Oversight of risk management is provided by the Board and the Audit Committee. The Directors regularly receive reports from, among others, management (including the Chief Risk Officer of the Adviser), the Company’s Chief Compliance Officer, the Company’s independent registered public accounting firm, the Adviser’s internal legal counsel, the Adviser’s Chief Compliance Officer and internal auditors for the Adviser, as appropriate, regarding risks faced by the Company and the Adviser’s risk management programs. In addition, the Directors receive regular updates on cyber security matters from the Adviser.

Not all risks that may affect the Company can be identified nor can controls be developed to eliminate or mitigate their occurrence or effects. It may not be practical or cost-effective to eliminate or mitigate certain risks, the processes and controls employed to address certain risks may be limited in their effectiveness, and some risks are simply beyond the reasonable control of the Company or the Adviser, its affiliates or other service providers. Moreover, it is necessary to bear certain risks (such as investment-related risks) to achieve the Company’s goals. As a result of the foregoing and other factors the Company’s ability to manage risk is subject to substantial limitations.

Board Committees. The Board has three standing committees — an Audit Committee, a Governance and Nominating Committee, and an Independent Directors Committee. The members of the Audit, Governance and Nominating, and Independent Directors Committees are identified above. The Advisory Board member is generally invited to attend all or portions of meetings of the committees.

The function of the Audit Committee is to assist the Board in its oversight of each Fund’s accounting and financial reporting policies and practices. The Audit Committee met three times during the Funds’ most recently completed fiscal year.

The function of the Governance and Nominating Committee includes the nomination of persons to fill any vacancies or newly created positions on the Board. The Governance and Nominating Committee met four times during the Funds’ most recently completed fiscal year.

The Board has adopted a charter for its Governance and Nominating Committee. Pursuant to the charter, the Committee assists the Board in carrying out its responsibilities with respect to governance of the Company and identifies, evaluates, selects and nominates candidates for the Board. The Committee may also set standards or qualifications for Directors and reviews at least annually the performance of each Director, taking into account factors such as attendance at meetings, adherence to Board policies, preparation for and participation at meetings, commitment and contribution to the overall work of the Board and its committees, and whether there are health or other reasons that might affect the Director’s ability to perform his or her duties. The Committee may consider candidates as Directors submitted by the Company’s current Board members, officers, the Adviser, shareholders and other appropriate sources.

Pursuant to the charter, the Governance and Nominating Committee will consider candidates for nomination as a Director submitted by a shareholder or group of shareholders who have beneficially owned at least 5% of the Fund’s common stock or shares of beneficial interest for at least two years at the time of submission and who timely provide specified information about the candidates and the nominating shareholder or group. To be timely for consideration by the Governance and Nominating Committee, the submission, including all required information, must be submitted in writing to the attention of the Secretary at the principal executive offices of the Fund no less than 120 days before the date of the proxy statement for the previous year’s annual meeting of shareholders. If the Fund did not hold an annual meeting of shareholders in the previous year, the submission must be delivered or mailed and received within a reasonable amount of time before the Fund begins to print and mail its proxy materials. Public notice of such upcoming annual meeting of shareholders may be given in a shareholder report or other mailing to shareholders or by other means deemed by the Governance and Nominating Committee or the Board to be reasonably calculated to inform shareholders.

Shareholders submitting a candidate for consideration by the Governance and Nominating Committee must provide the following information to the Governance and Nominating Committee: (i) a statement in writing setting forth (A) the name, date of birth, business address and residence address of the candidate; (B) any position or business relationship of the candidate, currently or within the preceding five years, with the shareholder or an associated person of the shareholder as defined below; (C) the class or series and number of all shares of a Fund owned of record or beneficially by the candidate; (D) any other information regarding the candidate that is required to be disclosed about a nominee in a proxy statement or other filing required to be made in connection with the solicitation of proxies for election of Directors pursuant to Section 20 of the 1940 Act and the rules and regulations promulgated thereunder; (E) whether the shareholder believes that the candidate is or will be an “interested person” of the Fund (as defined in the 1940 Act) and, if believed not to be an “interested person”, information regarding the candidate that will be sufficient for the Fund to make such determination; and (F) information as to the candidate’s knowledge of the investment company industry, experience as a director or senior officer of public companies, directorships on the boards of other registered investment companies and educational background; (ii) the written and signed consent of the candidate to be named as a nominee and to serve as a Director if elected; (iii) the written and signed agreement of the candidate to complete a directors’ and officers’ questionnaire if elected; (iv) the shareholder’s consent to be named as such by the Funds; (v) the class or series and number of all shares of the Funds owned beneficially and of record by the shareholder and any associated person of the shareholder and the dates on which such shares were acquired, specifying the number of shares owned beneficially but not of record by each, and stating the names of each as they appear on the Funds’ record books and the names of any nominee holders for each; and (vi) a description of all arrangements or understandings between the shareholder, the candidate and/or any other person or persons (including their names) pursuant to which the recommendation is being made by the shareholder. “Associated Person of the shareholder” means any person who is required to be identified under clause (vi) of this paragraph and any other person controlling, controlled by or under common control with, directly or indirectly, (a) the shareholder or (b) the associated person of the shareholder.

The Governance and Nominating Committee may require the shareholder to furnish such other information as it may reasonably require or deem necessary to verify any information furnished pursuant to the nominating procedures described above or to determine the

qualifications and eligibility of the candidate proposed by the shareholder to serve on the Board. If the shareholder fails to provide such other information in writing within seven days of receipt of written request from the Governance and Nominating Committee, the recommendation of such candidate as a nominee will be deemed not properly submitted for consideration, and will not be considered, by the Committee.

The Governance and Nominating Committee will consider only one candidate submitted by such a shareholder or group for nomination for election at an annual meeting of shareholders. The Governance and Nominating Committee will not consider self-nominated candidates. The Governance and Nominating Committee will consider and evaluate candidates submitted by shareholders on the basis of the same criteria as those used to consider and evaluate candidates submitted from other sources. These criteria include the candidate’s relevant knowledge, experience, and expertise, the candidate’s ability to carry out his or her duties in the best interests of the Company, and the candidate’s ability to qualify as an Independent Director. When assessing a candidate for nomination, the Committee considers whether the individual’s background, skills and experience will complement the background, skills and experience of other nominees and will contribute to the diversity of the Board.

The function of the Independent Directors Committee is to consider and take action on matters that the Board or Committee believes should be addressed in executive session of the Independent Directors, such as review and approval of the Advisory and Distribution Services Agreements. The Independent Directors Committee met nine times during the Funds’ most recently completed fiscal year.

Investment Professional Conflict of Interest Disclosure

As an investment adviser and fiduciary, the Adviser owes its clients and shareholders an undivided duty of loyalty. The Adviser recognizes that conflicts of interest are inherent in its business and accordingly has developed policies and procedures (including oversight monitoring) reasonably designed to detect, manage and mitigate the effects of actual or potential conflicts of interest in the area of employee personal trading, managing multiple accounts for multiple clients, including AB Mutual Funds, and allocating investment opportunities. Investment professionals, including portfolio managers and research analysts, are subject to the above-mentioned policies and oversight monitoring to ensure that all clients are treated equitably. The Adviser places the interests of its clients first and expects all of its employees to meet their fiduciary duties.

Employee Personal Trading. The Adviser has adopted a Code of Business Conduct and Ethics that is designed to detect and prevent conflicts of interest when investment professionals and other personnel of the Adviser own, buy or sell securities which may be owned by, or bought or sold for, clients. Personal securities transactions by an employee may raise a potential conflict of interest when an employee owns or trades in a security that is owned or considered for purchase or sale by a client, or recommended for purchase or sale by an employee to a client. Subject to the reporting requirements and other limitations of its Code of Business Conduct and Ethics, the Adviser permits its employees to engage in personal securities transactions, and also allows them to acquire investments in certain funds managed by the Adviser. The Adviser’s Code of Business Conduct and Ethics requires disclosure of all personal accounts and maintenance of brokerage accounts with designated broker-dealers approved by the Adviser. The Code of Business Conduct and Ethics also requires preclearance of all securities transactions (except transactions in U.S. Treasuries and open-end mutual funds other than funds advised by the Adviser) and imposes a 60-day holding period for securities purchased by employees to discourage short-term trading.

Managing Multiple Accounts for Multiple Clients. The Adviser has compliance policies and oversight monitoring in place to address conflicts of interest relating to the management of multiple accounts for multiple clients. Conflicts of interest may arise when an investment professional has responsibilities for the investments of more than one account because the investment professional may be unable to devote equal time and attention to each account. The investment professional or investment professional teams for each client may have responsibilities for managing all or a portion of the investments of multiple accounts with a common investment strategy, including other registered investment companies, unregistered

investment vehicles, such as hedge funds, pension plans, separate accounts, collective trusts and charitable foundations. Among other things, the Adviser’s policies and procedures provide for the prompt dissemination to investment professionals of initial or changed investment recommendations by analysts so that investment professionals are better able to develop investment strategies for all accounts they manage. In addition, investment decisions by investment professionals are reviewed for the purpose of maintaining uniformity among similar accounts and ensuring that accounts are treated equitably. Investment professional compensation reflects a broad contribution in multiple dimensions to long-term investment success for clients of the Adviser and is generally not tied specifically to the performance of any particular client’s account, nor is it generally tied directly to the level or change in level of assets under management.

Allocating Investment Opportunities and Order Aggregation. The investment professionals at the Adviser routinely are required to select and allocate investment opportunities among accounts. The Adviser has adopted policies and procedures intended to address conflicts of interest relating to the allocation of investment opportunities. These policies and procedures are designed to ensure that information relevant to investment decisions is disseminated promptly within its portfolio management teams and investment opportunities are allocated equitably among different clients, subject to the exceptions noted below. The policies and procedures require, among other things, objective allocation for limited investment opportunities (e.g., on a rotational basis), and documentation and review of justifications for any decisions to make investments only for select accounts or in a manner disproportionate to the size of the account. Portfolio holdings, position sizes, and industry and sector exposures tend to be similar across similar accounts, which minimizes the potential for conflicts of interest relating to the allocation of investment opportunities. Nevertheless, access to portfolio funds or other investment opportunities (including IPOs) may be allocated differently among accounts due to the particular characteristics of an account, such as size of the account, cash position, tax status, risk tolerance and investment restrictions or for other reasons. Additional information about the Adviser’s policy relating to the allocation of investment opportunities may be found in the Adviser’s Form ADV, which is updated from time to time.

Generally, all orders in the same security are aggregated in each trading system by the Adviser to facilitate best execution and to reduce overall trading costs. Executions for aggregated orders with the same executing broker are combined to determine one average price. The securities are then allocated to participating accounts using automated algorithms designed to achieve a fair, equitable and objective distribution of the securities over time. When the liquidity in a market is not sufficient to fill all client orders, the Adviser may give priority to certain orders over others. This prioritization is based on objective factors driving the order. Under such circumstances, the Adviser aggregates orders by these factors and subjects each aggregated order to the trade allocation algorithms discussed above. The factors used, in order of priority, are (1) correction of guideline breaches; (2) avoidance of guideline breaches; (3) investing significant new funding and completing tax strategy implementations; (4) investing in services that focus on specific financial instruments or market sectors; (5) avoidance of tracking error on the service/product level; and (6) portfolio rebalancing and optimization. Separate orders with the same priority may be traded using a rotational process that is fair and objective.

The Adviser may not require orders in the same security from different managers to be aggregated where one manager’s investment strategy requires rapid trade execution,

provided the Adviser believes that disaggregation will not materially impact other client orders. Certain other clients of the Adviser have investment objectives and policies similar to those of a Fund. The Adviser may, from time to time, make recommendations that result in the purchase or sale of a particular security by its other clients simultaneously with a purchase or sale thereof by one or more Funds. If transactions on behalf of more than one client during the same period increase the demand for securities being purchased or the supply of securities being sold, there may be an adverse effect on price or the quantity of securities available at a particular price. It is the policy of the Adviser to allocate advisory recommendations and the placing of orders in a manner that is deemed equitable by the Adviser to the accounts involved, including the Funds. When two or more clients of the Adviser (including a Fund) are purchasing or selling the same security on a given day through the same broker or dealer, such transactions are averaged as to price. The securities are then allocated to participating accounts using automated algorithms designed to achieve a fair, equitable and objective distribution of the securities over time.

The Adviser’s procedures are also designed to address potential conflicts of interest that may arise when the Adviser has a particular financial incentive, such as a performance-based management fee, relating to an account. The Adviser is conscious of these potential conflicts. When the Adviser is providing fiduciary services, the goal of the Adviser’s policies and procedures is to act in good faith and to treat all client accounts in a fair and equitable manner over time, regardless of their strategy, fee arrangements or the influence of their owners or beneficiaries.

Portfolio Manager Compensation

The Adviser’s compensation program for portfolio managers is designed to align with clients’ interests, emphasizing each portfolio manager’s ability to generate long-term investment success for the Adviser’s clients, including the Funds. The Adviser also strives to ensure that compensation is competitive and effective in attracting and retaining the highest caliber employees.

Portfolio managers receive a base salary, incentive compensation and contributions to AllianceBernstein’s 401(k) plan. Part of the annual incentive compensation is generally paid in the form of a cash bonus, and part through an award under the firm’s Incentive Compensation Award Plan (ICAP). The ICAP awards vest over a three-year period. Deferred awards are paid in the form of restricted grants of the firm’s Master Limited Partnership Units, and award recipients have the ability to receive a portion of their awards in deferred cash. The amount of contributions to the 401(k) plan is determined at the sole discretion of the Adviser. On an annual basis, the Adviser endeavors to combine all of the foregoing elements into a total compensation package that considers industry compensation trends and is designed to retain its best talent.

The incentive portion of total compensation is determined by quantitative and qualitative factors. Quantitative factors, which are weighted more heavily, are driven by investment performance. Qualitative factors are driven by contributions to the investment process and client success.

The quantitative component includes measures of absolute, relative and risk-adjusted investment performance. Relative and risk-adjusted returns are determined based on the benchmark in the Funds’ prospectus and versus peers over one-, three- and five-year calendar periods, with more weight given to longer-time periods. Peer groups are chosen by Chief

Investment Officers, who consult with the product management team to identify products most similar to our investment style and most relevant within the asset class. Portfolio managers of the Funds do not receive any direct compensation based upon the investment returns of any individual client account, and compensation is not tied directly to the level or change in level of assets under management.

Among the qualitative components considered, the most important include thought leadership, collaboration with other investment colleagues, contributions to risk-adjusted returns of other portfolios in the firm, efforts in mentoring and building a strong talent pool and being a good corporate citizen. Other factors can play a role in determining portfolio managers’ compensation, such as the complexity of investment strategies managed, volume of assets managed and experience.

The Adviser emphasizes four behavioral competencies—relentlessness, ingenuity, team orientation and accountability—that support its mission to be the most trusted advisor to its clients. Assessments of investment professionals are formalized in a year-end review process that includes 360-degree feedback from other professionals from across the investment teams and the Adviser.

Distribution Services Agreement

The Company has entered into a Distribution Services Agreement (the “Agreement”) with ABI, the Company’s principal underwriter, to permit ABI to distribute the Funds’ shares and to permit the Funds to pay distribution services fees to defray expenses associated with distribution of its Class A shares, Class C shares, Class 1 shares, Class R shares and Class K shares in accordance with a plan of distribution that is included in the Agreement and that has been duly adopted and approved in accordance with Rule 12b-1 adopted by the Commission under the 1940 Act (the “Plan”).

In approving the Plan, the Directors determined that there was a reasonable likelihood that the Plan would benefit each Fund and its shareholders. The distribution services fee of a particular class will not be used to subsidize the provision of distribution services with respect to any other class.

The Adviser, from time to time, and from its own funds or such other resources as may be permitted by rules of the Commission, makes payments for distribution services to ABI; the latter may in turn pay part or all of such compensation to brokers or other persons for their distribution assistance.

The Plan continues in effect with respect to each Fund and each class of shares thereof for successive one-year periods provided that such continuance is specifically approved at least annually by a majority of the Independent Directors of the Company who have no direct or indirect financial interest in the operation of the Plan or any agreement related thereto (the “Qualified Directors”) and by a vote of a majority of the entire Board at a meeting called for that

purpose. Most recently, the Directors approved the continuance of the Plan for an additional annual term at their meetings held on August 1-2, 2023.

All material amendments to the Plan will become effective only upon approval as provided in the preceding paragraph; and the Plan may not be amended in order to increase materially the costs that a Fund may bear pursuant to the Plan without the approval of a majority of the holders of the outstanding voting shares of the Fund or the class or classes of the Fund affected.

The Agreement may be terminated (a) by any Fund without penalty at any time by a majority vote of the holders of a Fund’s outstanding voting securities voting separately by class or by majority vote of the Qualified Directors, or (b) by ABI. To terminate the Plan or the Agreement, any party must give the other party 60 days’ prior written notice, except that a Fund may terminate the Plan without giving prior notice to ABI. The Agreement will terminate automatically in the event of an assignment. The Plan is of a type known as a “reimbursement plan”, which means that it compensates the distributor for the actual costs of services rendered.

In the event that the Plan is terminated by either party or not continued with respect to the Class A, Class C, Class 1, Class R or Class K shares, (i) no distribution services fees (other than current amounts accrued but not yet paid) would be owed by a Fund to ABI with respect to that class, and (ii) a Fund would not be obligated to pay ABI for any amounts expended under the Agreement not previously recovered by ABI from distribution services fees in respect of shares of such class or through deferred sales charges.

During the fiscal year ended October 31, 2023, for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, with respect to Class A shares, the distribution services fees for expenditures payable to ABI were as follows:

_________________

*       The maximum fee allowed under the Rule 12b-1 Plan for the Class A shares of the Funds is .30% of the aggregate average daily net assets. The Board currently limits the payments to .25%.

For the fiscal year ended October 31, 2023 for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, expenses incurred by each Fund and costs allocated to each Fund in connection with activities primarily intended to result in the sale of Class A shares were as follows:

During the fiscal year ended October 31, 2023, for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, with respect to Class C shares, the distribution services fees for expenditures payable to ABI were as follows:

For the fiscal year ended October 31, 2023 for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, expenses incurred by each Fund and costs allocated to each Fund in connection with activities primarily intended to result in the sale of Class C shares were as follows:

During the fiscal year ended October 31, 2023, for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, with respect to Class 1 shares, the distribution services fees for expenditures payable to ABI were as follows:

For the fiscal year ended October 31, 2023 for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, expenses incurred by each Fund and costs allocated to each Fund in connection with activities primarily intended to result in the sale of Class 1 shares were as follows:

Distribution services fees are accrued daily and paid monthly and charged as expenses of each Fund as accrued. The distribution services fees attributable to the Class C, Class 1, Class R and Class K shares of each Fund are designed to permit an investor to purchase such shares through broker-dealers without the assessment of an initial sales charge, and at the same time to permit ABI to compensate broker-dealers in connection with the sale of such shares. In this regard, the purpose and function of the combined contingent deferred sales charge (“CDSC”) and respective distribution services fee on the Class C shares of each Fund and the distribution services fees on the Class 1 shares, Class R shares and the Class K shares of each Fund are the same as those of the initial sales charge and distribution services fee with respect to the Class A shares of each Fund in that in each case the sales charge and/or distribution services fee provides for the financing of the distribution of the relevant class of the relevant Fund’s shares.

With respect to Class A shares of each Fund, distribution expenses accrued by ABI in one fiscal year may not be paid from distribution services fees received from the Fund in subsequent fiscal years. ABI’s compensation with respect to Class C, Class 1, Class R and Class K shares of each Fund under the Plan is directly tied to the expenses incurred by ABI. Actual distribution expenses for Class C shares, Class 1 shares, Class R shares and Class K shares of each Fund for any given year, however, will probably exceed the distribution services fee payable under the Plan with respect to the class involved and, in the case of Class C shares of each Fund, payments received from CDSCs. The excess will be carried forward by ABI and reimbursed from distribution services fees payable under the Plan with respect to the class involved and, in the case of Class C shares, payments subsequently received through CDSCs, so long as the Plan is in effect.

For the fiscal year ended October 31, 2023 for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, unreimbursed distribution

expenses incurred and carried over of reimbursement in future years in respect of the Class C, Class R, Class K and Class 1 shares of each Fund, as applicable, were as follows:

Transfer Agency Agreement

ABIS, an indirect wholly-owned subsidiary of the Adviser located principally at 8000 IH 10 W, 13^th Floor, San Antonio, Texas 78230, acts as the transfer agent for the Funds. ABIS registers the transfer, issuance and redemption of Fund shares and disburses dividends and other distributions to Fund shareholders, receives a transfer agency fee per account holder of each of the Class A, Class C, Class 1, Class 2, Class R, Class K, Class I and Advisor Class shares of the Funds, plus reimbursement for out-of-pocket expenses. For the fiscal year ended October 31, 2023 for Bond Inflation Strategy, Municipal Bond Inflation Strategy and All Market Real Return Portfolio, the Company paid ABIS $187,182, $135,006 and $152,913, respectively, for transfer agency services.

Many Fund shares are owned by selected dealers or selected agents, as defined below, financial intermediaries or other financial representatives (“financial intermediaries”) for the benefit of their customers. In those cases, the Funds often do not maintain an account for the beneficial owner of the Fund’s shares. Thus, some or all of the transfer agency functions for these accounts are performed by the financial intermediaries. Retirement plans may also hold Fund shares in the name of the plan, rather than the participant. Financial intermediaries and recordkeepers, which may have affiliated financial intermediaries that sell shares of the AB Mutual Funds, may be paid by the Fund, the Adviser, ABI and ABIS (i) account fees in amounts up to $19 per account per annum, (ii) asset-based fees of up to 0.25% (except in respect of a limited number of intermediaries) per annum of the average daily assets held through the intermediary, or (iii) a combination of both. These amounts include fees for shareholder servicing, sub-transfer agency, sub-accounting and recordkeeping services. These amounts do not include fees for shareholder servicing that may be paid separately by a Fund pursuant to its Rule 12b-1 plan. Amounts paid by a Fund for these services are included in “Other Expenses” under

“Fees and Expenses of the Fund” in the Summary Information section of the Prospectus. In addition, financial intermediaries may be affiliates of entities that receive compensation from the Adviser or ABI for maintaining retirement plan “platforms” that facilitate trading by affiliated and non-affiliated financial intermediaries and recordkeeping for retirement plans.

Because financial intermediaries and plan recordkeepers may be paid varying amounts per class for sub-transfer agency and related recordkeeping services, the service requirements of which may also vary by class, this may create an additional incentive for financial intermediaries and their financial advisors to favor one fund complex over another or one class of shares over another.

Securities Lending Agreement

The following information supplements that set forth in your Prospectus under the heading “Investing in the Funds”.

General

Shares of the Funds are offered on a continuous basis at a price equal to their NAV plus an initial sales charge at the time of purchase (the “Class A shares”), without any initial sales charge and, as long as the shares are held for one year or more, without any CDSC (the “Class C shares”), to private clients (“Clients”) of Sanford C. Bernstein & Co. LLC (“Bernstein”) without any initial sales charge or CDSC (the “Class 1 shares”), to institutional clients of the Adviser and Bernstein Clients who have at least $3 million in fixed-income assets under management with Bernstein without any initial sales charge or CDSC (the “Class 2 shares”), or to investors eligible to purchase Advisor Class shares, without any initial sales charge or CDSC (the “Advisor Class shares”), and, except for Municipal Bond Inflation Strategy, to Group Retirement Plans, as defined below, eligible to purchase Class R shares, without any initial sales charge or CDSC (the “Class R shares”), to Group Retirement Plans eligible to purchase Class K shares, without any initial sales charge or CDSC (the “Class K shares”), to Group Retirement Plans and certain investment advisory clients of, and certain other persons associated with, the Adviser and its affiliates eligible to purchase Class I shares, without any initial sales charge or CDSC (the “Class I shares”), with respect to Bond Inflation Strategy and All Market Real Return Portfolio to investors eligible to purchase Class Z shares, without any initial sales charge or CDSC (“Class Z shares”), in each case as described below. All of the classes of shares of the Funds, except Class 2, Advisor Class, Class I and Class Z shares, are subject to Rule 12b-1 asset-based sales charges. Shares of the Funds that are offered subject to a sales charge are offered through (i) investment dealers that are members of the Financial Industry Regulatory Authority (“FINRA”) and have entered into selected dealer agreements with ABI (“selected dealers”), (ii) depository institutions and other financial intermediaries or their affiliates, that have entered into selected agent agreements with ABI (“selected agents”) and (iii) ABI.

Investors may purchase shares of the Funds either through financial intermediaries or directly through ABI. A transaction, service, administrative or other similar fee may be charged by your financial intermediary with respect to the purchase, sale or exchange of shares of each Fund made through such financial intermediary. Such financial intermediaries may also impose requirements with respect to the purchase, sale or exchange of shares that are different from, or in addition to, those imposed by the Funds, including requirements as to the classes of shares available through that financial intermediary and the minimum initial and subsequent investment amounts. The Funds are not responsible for, and have no control over, the decision of any financial intermediary to impose such differing requirements. Sales personnel of financial intermediaries distributing the Funds’ shares may receive differing compensation for selling different classes of shares.

In order to open your account, a Fund or your financial intermediary is required to obtain certain information from you for identification purposes. This information may include name, date of birth, physical address, social security/taxpayer identification number, and

ownership/control information (for certain legal entities). Ownership/control information for legal entities may include the name, date of birth, physical address, and identification number (generally a social security or taxpayer identification number) of owners/controlling persons. It will not be possible to establish your account without this information. If the Fund or your financial intermediary is unable to verify the information provided, your account may be closed and other appropriate action may be taken as permitted by law.

Bond Inflation Strategy and All Market Real Return Portfolio each no longer offer Class R or Class K shares to new investors. Class R shares and Class K shares of each Fund will be liquidated on or about May 21, 2024.

Frequent Purchases and Sales of Fund Shares

The Board has adopted policies and procedures designed to detect and deter frequent purchases and redemptions of Fund shares or excessive or short-term trading that may disadvantage long-term Fund shareholders. These policies are described below. There is no guarantee that a Fund will be able to detect excessive or short-term trading or to identify shareholders engaged in such practices, particularly with respect to transactions in omnibus accounts. Shareholders should be aware that application of these policies may have adverse consequences, as described below, and should avoid frequent trading in Fund shares through purchases, sales and exchanges of shares. The Funds reserve the right to restrict, reject or cancel, without any prior notice, any purchase or exchange order for any reason, including any purchase or exchange order accepted by any shareholder’s financial intermediary.

Risks Associated With Excessive or Short-Term Trading Generally. While the Funds will try to prevent market timing by utilizing the procedures described below, these procedures may not be successful in identifying or stopping excessive or short-term trading in all circumstances. By realizing profits through short-term trading, shareholders that engage in rapid purchases and sales or exchanges of a Fund’s shares dilute the value of shares held by long-term shareholders. Volatility resulting from excessive purchases and sales or exchanges of Fund shares, especially involving large dollar amounts, may disrupt efficient portfolio management and cause a Fund to sell shares at inopportune times to raise cash to accommodate redemptions relating to short-term trading. In particular, a Fund may have difficulty implementing its long-term investment strategies if it is forced to maintain a higher level of its assets in cash to accommodate significant short-term trading activity. In addition, a Fund may incur increased administrative and other expenses due to excessive or short-term trading, including increased brokerage costs and realization of taxable capital gains.

A Fund that may invest significantly in securities of foreign issuers may be particularly susceptible to short-term trading strategies. This is because securities of foreign issuers are typically traded on markets that close well before the time each Fund ordinarily calculates its NAV at 4:00 p.m., Eastern time, which gives rise to the possibility that developments may have occurred in the interim that would affect the value of these securities. The time zone differences among international stock markets can allow a shareholder engaging in a short-term trading strategy to exploit differences in Fund share prices that are based on closing prices of securities of foreign issuers established some time before the Fund calculates its own share price (referred to as “time zone arbitrage”). A Fund has procedures, referred to as fair value pricing, designed to adjust closing market prices of securities of foreign issuers to reflect what is believed to be the fair value of those securities at the time the Fund calculates its NAV. While

there is no assurance, the Funds expect that the use of fair value pricing, in addition to the short-term trading policies discussed below, will significantly reduce a shareholder’s ability to engage in time zone arbitrage to the detriment of other Fund shareholders.

A shareholder engaging in a short-term trading strategy may also target a Fund that does not invest primarily in securities of foreign issuers. Any Fund that invests in securities that are, among other things, thinly traded or traded infrequently, or that have a limited public float has the risk that the current market price for the securities may not accurately reflect current market values. A shareholder may seek to engage in short-term trading to take advantage of these pricing differences (referred to as “price arbitrage”). All Funds may be adversely affected by price arbitrage.

Policy Regarding Short-Term Trading. Purchases and exchanges of shares of a Fund should be made for investment purposes only. A Fund will seek to prevent patterns of excessive purchases and sales or exchanges of Fund shares. The Funds seek to prevent such practices to the extent they are detected by the procedures described below, subject to the Funds’ ability to monitor purchase, sale and exchange activity. A Fund reserves the right to modify this policy, including any surveillance or account blocking procedures established from time to time to effectuate this policy, at any time without notice.

an unsuitable investment. A blocked account will generally remain blocked for 90 days. Subsequent detections of excessive or short-term trading may result in an indefinite account block or an account block until the account holder or the associated broker, dealer or other financial intermediary provides evidence or assurance acceptable to the Fund that the account holder did not or will not in the future engage in excessive or short-term trading.

Purchase of Shares

A Fund reserves the right to suspend the sale of its shares to the public in response to conditions in the securities markets or for other reasons. If a Fund suspends the sale of its shares, shareholders will not be able to acquire its shares, including through an exchange.

In addition, to the extent permitted by law, a Fund reserves the right to merge or reorganize itself or a share class, or to close and liquidate itself or a share class at any time.

The public offering price of shares of each Fund is its NAV, plus, in the case of Class A shares of the Fund, a sales charge. On each Fund business day on which a purchase or redemption order is received by the Fund and trading in the types of securities in which the Fund invests might materially affect the value of the Fund’s shares, the NAV per share is computed at the Fund Closing Time, which is the close of regular trading on each day the Exchange is open (ordinarily 4:00 p.m., Eastern time, but sometimes earlier, as in the case of scheduled half-day trading or unscheduled suspensions of trading) by dividing the value of the total assets attributable to a class, less its liabilities, by the total number of its shares then outstanding. A Fund business day is any day on which the Exchange is open for trading.

The respective NAVs of the various classes of shares of a Fund are expected to be substantially the same. However, the NAVs of the Class C and Class R shares of the Fund will generally be slightly lower than the NAVs of the Class A, Class 1, Class 2, Class K, Class I, Class Z and Advisor Class shares of the Fund as a result of the differential daily expense accruals of the higher distribution and, in some cases, transfer agency fees applicable with respect to those classes of shares.

A Fund will accept unconditional orders for its shares to be executed at the public offering price equal to its NAV next determined (plus applicable Class A sales charges), as described below. Orders received by ABIS prior to the Fund Closing Time on each day the Exchange is open are priced at the NAV next computed on that day (plus applicable Class A sales charges). In the case of orders for purchases of shares placed through financial intermediaries, the applicable public offering price will be the NAV as so determined, but only if the financial intermediary receives the order prior to the Fund Closing Time. The financial intermediary is responsible for transmitting such orders by a prescribed time to a Fund or its transfer agent. If the financial intermediary receives the order after the Fund Closing Time, the price received by the investor will be based on the NAV determined as of the Fund Closing Time on the next business day. Each Fund has authorized one or more brokers to receive on its behalf purchase orders. Such brokers are authorized to designate other intermediaries to receive purchase orders on the Fund’s behalf. In such cases, orders will receive the NAV next computed after such order is properly received by the authorized broker or designee and accepted by the Fund.

A Fund may, at its sole option, accept securities as payment for shares of the Fund, including from certain affiliates of the Company in accordance with the Company’s procedures, if the Adviser believes that the securities are appropriate investments for the Fund. The securities are valued by the method described under “Net Asset Value” below as of the date the Fund receives the securities and corresponding documentation necessary to transfer the securities to the Fund. This is a taxable transaction to the shareholder.

Following the initial purchase of a Fund’s shares, a shareholder may place orders to purchase additional shares by telephone if the shareholder has completed the appropriate portion of the Mutual Fund Application or an “Autobuy” application, both of which may be obtained by calling the “For Literature” telephone number shown on the cover of this SAI. Except with respect to certain omnibus accounts, telephone purchase orders with payment by electronic funds transfer may not exceed $500,000. Payment for shares purchased by telephone can be made only by electronic funds transfer from a bank account maintained by the shareholder at a bank that is a member of the National Automated Clearing House Association (“NACHA”). Telephone purchase requests must be received before the Fund Closing Time on a Fund business day to receive that day's public offering price. Telephone purchase requests received after the Fund Closing Time, are automatically placed the following Fund business day, and the applicable public offering price will be the public offering price determined as of the Fund Closing Time on the following business day.

Full and fractional shares are credited to a shareholder’s account in the amount of his or her subscription. As a convenience, and to avoid unnecessary expense to the Fund, the Fund will not issue share certificates representing shares of the Fund. Ownership of the Fund’s shares will be shown on the books of the Company’s transfer agent.

Each class of shares in a Fund represents an interest in the same portfolio of investments of that Fund, has the same rights and is identical in all respects, except that (i) Class A shares bear the expense of the initial sales charge (or CDSC, when applicable) and Class C shares bear the expense of the CDSC, (ii) depending on the Fund, Class C and Class R shares typically each bear the expense of a higher distribution services fee than those borne by Class A, Class 1 and Class K shares and Class I, Class 2, Class Z and Advisor Class shares do not bear

such a fee, (iii) Class C shares are subject to a conversion feature and will convert to Class A shares under certain circumstances; and (iv) each of Class A, Class C, Class 1, Class R and Class K shares has exclusive voting rights with respect to provisions of the Plan pursuant to which its distribution services fee is paid and other matters for which separate class voting is appropriate under applicable law, provided that, if each Fund submits to a vote of the Class A shareholders an amendment to the Rule 12b-1 Plan that would materially increase the amount to be paid thereunder with respect to the Class A shares, then such amendment will also be submitted to Class C shareholders because the Class C shares convert to Class A shares under certain circumstances, and the Class A and Class C shareholders will vote separately by class. Each class has different exchange privileges and certain different shareholder service options available.

The Directors have determined that currently no conflict of interest exists between or among the classes of shares of the Fund. On an ongoing basis, the Directors, pursuant to their fiduciary duties under the 1940 Act and state law, will seek to ensure that no such conflict arises.

Alternative Purchase Arrangements

Classes A and C Shares. Class A and Class C shares have the following alternative purchase arrangements: Class A shares are generally offered with an initial sales charge and Class C shares are sold to investors choosing the asset-based sales charge alternative. Special purchase arrangements are available for Group Retirement Plans. “Group Retirement Plans” are defined as 401(k) plans, 457 plans, employer-sponsored 403(b) plans, profit sharing and money purchase pension plans, defined benefit plans, and non-qualified deferred compensation plans where plan level or omnibus accounts are held on the books of a Fund. See “Alternative Purchase Arrangements – Group Retirement Plans and Tax-Deferred Accounts” below. These alternative purchase arrangements permit an investor to choose the method of purchasing shares that is most beneficial given the amount of the purchase, the length of time the investor expects to hold the shares, and other circumstances. Investors should consider whether, during the anticipated life of their investment in a Fund, the accumulated distribution services fee and CDSC on Class C shares prior to conversion would be less than the initial sales charge and accumulated distribution services fee on Class A shares purchased at the same time, and to what extent such differential would be offset by the higher return of Class A shares. Class C shares will normally not be suitable for the investor who qualifies to purchase Class A shares at NAV. For this reason, ABI will reject any order for more than $500,000 for Class C shares with respect to Bond Inflation Strategy and Municipal Bond Inflation Strategy.

Class A shares are subject to a lower distribution services fee and, accordingly, pay correspondingly higher dividends per share than Class C shares. However, because initial sales charges are deducted at the time of purchase, most investors purchasing Class A shares would not have all of their funds invested initially and, therefore, would initially own fewer shares. Investors not qualifying for reduced initial sales charges who expect to maintain their investment for an extended period of time might consider purchasing Class A shares because the accumulated continuing distribution charges on Class C shares may exceed the initial sales charge on Class A shares during the life of the investment. Again, however, such investors must weigh this consideration against the fact that, because of such initial sales charges, not all their funds will be invested initially.

Other investors might determine, however, that it would be more advantageous to purchase Class C shares in order to have all their funds invested initially, although remaining

subject to higher continuing distribution charges and being subject to a CDSC for a one-year period. For example, based on current fees and expenses, an investor subject to the 4.25% initial sales charge on Class A shares of All Market Real Return Portfolio would have to hold his or her investment approximately seven years for the Class C distribution services fee to exceed the initial sales charge plus the accumulated distribution services fee of Class A shares. In this example, an investor intending to maintain his or her investment for a longer period might consider purchasing Class A shares. This example does not take into account the time value of money, which further reduces the impact of the Class C distribution services fees on the investment, fluctuations in NAV or the effect of different performance assumptions.

Compensation Paid to Principal Underwriter

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the aggregate amount of underwriting commission payable with respect to Class A shares of Bond Inflation Strategy was $51,654, $219,882 and $286,722, respectively. Of that amount ABI received amounts of $3,464, $10,072 and $16,760, respectively, representing that portion of the sales charges paid on shares of the Fund sold during the year which was not re-allowed to selected dealers (and was, accordingly, retained by ABI).

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the aggregate amount of underwriting commission payable with respect to Class A shares of Municipal Bond Inflation Strategy was $126,633, $1,009,951 and $2,086,375, respectively. Of that amount ABI received amounts of $134, $0 and $0, respectively, representing that portion of the sales charges paid on shares of the Fund sold during the year which was not re-allowed to selected dealers (and was, accordingly, retained by ABI).

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, the aggregate amount of underwriting commission payable with respect to Class A shares of All Market Real Return Portfolio was $12,252, $12,777 and $893, respectively. Of that amount ABI received amounts of $834, $955 and $28, respectively, representing that portion of the sales charges paid on shares of the Fund sold during the year which was not re-allowed to selected dealers (and was, accordingly, retained by ABI).

The following table shows the CDSCs received by ABI from each share class during the Funds’ last three fiscal years.

Class A Shares. The public offering price of Class A shares is the NAV per share plus a sales charge, as set forth below.

All or a portion of the initial sales charge may be paid to your financial representative. With respect to purchases of $1,000,000 or more for All Market Real Return Portfolio, $500,000 or more for Municipal Bond Inflation Strategy, or $500,000 or more for Bond Inflation Strategy, Class A shares redeemed within one year of purchase may be subject to a CDSC of up to 1% (18 months for Bond Inflation Strategy). The CDSC on Class A shares will be waived on certain redemptions, as described below under “—Contingent Deferred Sales Charge”. The Funds receive the entire NAV of their Class A shares sold to investors. ABI’s commission is the sales charge shown in the Prospectus less any applicable discount or commission “re-allowed” to selected dealers and agents. ABI will re-allow discounts to selected dealers and agents in the amounts indicated in the table above. In this regard, ABI may elect to re-allow the entire sales charge to selected dealers and agents for all sales with respect to which orders are placed with ABI. A selected dealer who receives a re-allowance in excess of 90% of such a sales charge may be deemed to be an “underwriter” under the Securities Act.

No initial sales charge is imposed on Class A shares issued (i) pursuant to the automatic reinvestment of income dividends or capital gains distributions or (ii) in exchange for Class A shares of other “AB Mutual Funds” (as that term is defined under “Combined Purchase Privilege” below), except that an initial sales charge will be imposed on Class A shares issued in exchange for Class A shares of AB Government Money Market Portfolio that were purchased for cash without the payment of an initial sales charge and without being subject to a CDSC. The Fund receives the entire NAV of its Class A shares sold to investors. ABI’s commission is the sales charge shown in the Prospectus less any applicable discount or commission “re-allowed” to selected dealers and agents. ABI will re-allow discounts to selected dealers and agents in the amounts indicated in the table above. In this regard, ABI may elect to re-allow the entire sales charge to selected dealers and agents for all sales with respect to which orders are placed with ABI. A selected dealer who receives reallowance in excess of 90% of such a sales charge may be deemed to be an “underwriter” under the Securities Act.

Commissions may be paid to selected dealers or agents who initiate or are responsible for Class A share purchases by a single shareholder of $500,000 or more for Municipal Bond Inflation Strategy and $500,000 or more for Bond Inflation Strategy that are not subject to an initial sales charge at up to the following rates: 1.00% on purchase amounts up to $5,000,000; plus 0.50% on purchase amounts over $5,000,000. Commissions may be paid to selected dealers or agents who initiate or are responsible for Class A share purchases by a single shareholder of $1,000,000 or more for All Market Real Return Portfolio that are not subject to an initial sales charge at up to the following rates: 1.00% on purchases up to $3,000,000; 0.75% on purchases over $3,000,000 to $5,000,000; and 0.50% on purchases over $5,000,000. Commissions are paid based on cumulative purchases by a shareholder over the life of an account with no adjustments for redemptions, transfers or market declines.

In addition to the circumstances described above, certain types of investors may be entitled to pay no initial sales charge in certain circumstances described below.

Class A Shares--Sales at NAV. A Fund may sell its Class A shares at NAV (i.e., without any initial sales charge) to certain categories of investors including:

Class C Shares. Investors may purchase Class C shares at the public offering price equal to the NAV per share of the Class C shares on the date of purchase without the imposition of a sales charge either at the time of purchase or, as long as the shares are held for one year or more, upon redemption. Class C shares are sold without an initial sales charge, so that a Fund will receive the full amount of the investor’s purchase payment and, as long as the shares are held for one year or more, without a CDSC so that the investor will receive as proceeds upon redemption the entire NAV of his or her Class C shares. The Class C distribution services fee enables a Fund to sell Class C shares without either an initial sales charge or CDSC, as long as the shares are held for one year or more. Class C shares incur higher distribution services fees and transfer agency costs than Class A shares and Advisor Class shares, and will thus have a higher expense ratio and pay correspondingly lower dividends than Class A shares and Advisor Class shares.

Eight years after the end of the calendar month in which the shareholder’s purchase order was accepted Class C shares will automatically convert to Class A shares and will no longer be subject to a higher distribution services fee. Such conversion will occur on the basis of the relative NAVs of the two classes, without the imposition of any sales load, fee or other charge. The purpose of the conversion feature is to reduce the distribution services fee paid by holders of Class C shares that have been outstanding long enough for ABI to have been compensated for distribution expenses incurred in the sale of the shares.

Conversion Feature for Class C Shares. For purposes of conversion to Class A shares, Class C shares purchased through the reinvestment of dividends and distributions paid in respect of such shares in a shareholder’s account will be considered to be held in a separate sub-account. Each time any Class C shares in the shareholder’s account (other than those in the sub-account) convert to Class A shares, an equal pro-rata portion of such shares in the sub-account will also convert to Class A shares.

The conversion to Class A shares is subject to the continuing availability of an opinion of counsel to the effect that the conversion of Class C shares to Class A shares does not constitute a taxable event under federal income tax law. The conversion of Class C shares to Class A shares may be suspended if such an opinion is no longer available at the time such conversion is to occur. In that event, no further conversions of Class C shares would occur, and shares might continue to be subject to the higher distribution services fee for an indefinite period,

which may extend beyond the period ending eight years after the end of the calendar month in which the shareholder’s purchase order was accepted.

Contingent Deferred Sales Charge. Class A share purchases of $1,000,000 or more with respect to All Market Real Return Portfolio; Class A share purchases of $500,000 or more with respect to Municipal Bond Inflation Strategy; Class A share purchases of $500,000 or more, with respect to Bond Inflation Strategy; and all purchases of Class C shares that are redeemed within one year of purchase (18 months for Class A share purchases of Bond Inflation Strategy) are subject to a CDSC of 1%, as are Class A share purchases by certain Group Retirement Plans (see “Alternative Purchase Arrangements – Group Retirement Plans and Tax-Deferred Accounts” below). The charge will be assessed on an amount equal to the lesser of the cost of the shares being redeemed or their NAV at the time of redemption. Accordingly, no sales charge will be imposed on increases in NAV above the initial purchase price. In addition, no charge will be assessed on shares derived from reinvestment of dividends or capital gains distributions.

In determining the CDSC applicable to a redemption of Class C shares, it will be assumed that the redemption is, first, of any shares that are not subject to a CDSC (for example, because the shares were acquired upon the reinvestment of dividends or distributions) and, second, of shares held longest during the time they are subject to the sales charge. When shares acquired in an exchange are redeemed, the applicable CDSC and conversion schedules will be the schedules that applied at the time of the purchase of shares of the corresponding class of the AB Mutual Fund originally purchased by the shareholder.

Proceeds from the CDSC are paid to ABI and are used by ABI to defray the expenses of ABI related to providing distribution-related services to a Fund in connection with the sale of Fund shares, such as the payment of compensation to selected dealers and agents for selling Fund shares. The combination of the CDSC and the distribution services fee enables the Fund to sell shares without a sales charge being deducted at the time of purchase.

The CDSC is waived on redemptions of shares (i) following the death or disability, as defined in the Code, of a shareholder, (ii) to the extent that the redemption represents a minimum required distribution from an individual retirement account or other retirement plan to a shareholder that has attained the age of 73, (iii) that had been purchased by present or former Directors, by the relative of any such person, by any trust, individual retirement account or retirement plan account for the benefit of any such person or relative or by the estate of any such person or relative, (iv) pursuant to, and in accordance with, a systematic withdrawal plan (see “Sales Charge Reduction Programs – Systematic Withdrawal Plan” below), (v) to the extent that the redemption is necessary to meet a plan participant’s or beneficiary’s request for a distribution or loan from a Group Retirement Plan or to accommodate a plan participant’s or beneficiary’s direction to reallocate his or her plan account among other investment alternatives available under a Group Retirement Plan, (vi) due to the complete termination of a trust upon the death of the trustor/grantor, beneficiary or trustee but only if the trust termination is specifically provided for in the trust document, or (vii) that had been purchased with proceeds from a Distribution resulting from any Commission enforcement action related to trading in shares of AB Mutual Funds through deposit with ABI of the Distribution check. The CDSC is also waived for (i) permitted exchanges of shares, (ii) holders of Class A shares who purchased $1,000,000 or more of Class A shares where the participating broker or dealer involved in the sale of such shares waived the

commission it would normally receive from ABI or (iii) Class C shares sold through programs offered by financial intermediaries and approved by ABI where such programs offer only shares that are not subject to a CDSC, where the financial intermediary establishes a single omnibus account for each Fund or, in the case of a Group Retirement Plan, a single account for each plan, and where no advance commission is paid to any financial intermediary in connection with the purchase of such shares.

Class 1 Shares. Class 1 shares are offered only to Bernstein Clients. Class 1 shares incur a .25% distribution services fee and thus have a lower expense ratio and pay correspondingly higher dividends than Class C shares.

Class 2 Shares. Class 2 shares are offered only to institutional clients of the Adviser and Bernstein Clients who have at least $3 million in fixed-income assets under management with Bernstein after giving effect to their investment in the Funds. Class 2 shares do not incur any distribution services fees and will thus have a lower expense ratio and pay correspondingly higher dividends than Class A, Class C and Class 1 shares.

Asset Allocation. Bernstein may, at a Client’s request, maintain a specified percentage of the Client’s assets in one or more of the Funds, or vary the percentage based on Bernstein’s opinion of a client’s asset allocation. In keeping with these Client mandates or for tax considerations, Bernstein may, without additional instructions from the Client, purchase or sell Class 1 and Class 2 shares of any Fund from time to time.

Class R Shares. (not offered for Municipal Bond Inflation Strategy). Class R shares are offered to certain Group Retirement Plans. Class R shares are not available to retail non-retirement accounts, traditional or Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs, individual 403(b) plans and to AllianceBernstein-sponsored retirement products. Bond Inflation Strategy and All Market Real Return Portfolio each suspended sales of Class R shares to new investors effective November 3, 2023. Underlying shareholders who currently hold Class R shares though Group Retirement Plans may continue to purchase such shares until May 16, 2024. Each Fund expects to liquidate all assets corresponding to its Class R shares and make liquidating distributions to its respective shareholders on or about May 21, 2024. Class R shares do not have an initial sales charge or CDSC, but incur a .50% distribution services fee and thus have a higher expense ratio and pay correspondingly lower dividends than Class A shares, Class K shares and Class I shares.

Class K Shares. (not offered for Municipal Bond Inflation Strategy). Class K shares are available at NAV to Group Retirement Plans. Class K shares generally are not available to retail non-retirement accounts, traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs, and individual 403(b) plans. Bond Inflation Strategy and All Market Real Return Portfolio each suspended sales of Class K shares to new investors effective November 3, 2023. Underlying shareholders who currently hold Class K shares though Group Retirement Plans may continue to purchase such shares until May 16, 2024. Each Fund expects to liquidate all assets corresponding to its Class K shares and make liquidating distributions to its respective shareholders on or about May 21, 2024. Class K shares do not have an initial sales charge or CDSC but incur a .25% distribution services fee and thus have (i) a lower expense ratio than Class R shares and pay correspondingly higher dividends than Class R shares and (ii) a higher expense ratio than Class I shares and pay correspondingly lower dividends than Class I shares.

Class I Shares. (not offered for Municipal Bond Inflation Strategy). Class I shares are available at NAV to Group Retirement Plans. Class I shares are also available to certain institutional investment advisory clients of, and certain other persons associated with, the Adviser and its affiliates who invest at least $2 million in the Fund. Class I shares generally are not available to retail non-retirement accounts, traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs, individual 403(b) plans and AllianceBernstein-sponsored retirement programs known as the “Informed Choice” programs. Class I shares are not subject to an initial sales charge, CDSC or distribution services fee, and thus have a lower expense ratio and pay correspondingly higher dividends than Class R and Class K shares.

Class Z Shares. (not offered for Municipal Bond Inflation Strategy). Class Z shares are available at NAV to certain Group Retirement Plans. Class Z shares generally are not available to traditional and Roth IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs and individual 403(b) plans. Class Z shares are not currently available to Group Retirement Plans in the AllianceBernstein-sponsored retirement programs known as the “Informed Choice” programs. Class Z shares are also available to certain institutional investment advisory clients of, and certain other persons associated with, the Adviser and its affiliates who invest at least $2 million in the Fund. Class Z shares are also available to persons participating in certain fee-based programs sponsored and maintained by registered broker-dealers or other financial intermediaries with omnibus account arrangements with a Fund.

Class Z shares are not subject to an initial sales charge, CDSC or distribution services fee, and thus have a lower expense ratio and pay correspondingly higher dividends than Class R and Class K shares.

Advisor Class Shares. Advisor Class shares may be purchased and held solely (i) through accounts established under fee-based programs, sponsored and maintained by registered broker-dealers or other financial intermediaries and approved by ABI; (ii) through self-directed defined contribution employee benefit plans (e.g., 401(k) plans) that purchase shares directly without the involvement of a financial intermediary; (iii) by officers and present or former Directors of the Funds or other investment companies managed by the Adviser, officers, directors and present or retired full-time employees and former employees (for subsequent investments in accounts established during the course of their employment) of the Adviser, ABI, ABIS and their affiliates; or the relatives of any such person; or any trust, individual retirement account or retirement plan for the benefit of any such person; (iv) by the categories of investors described in clauses (i), (iii) and (iv) under “Class A Shares - Sales at NAV”; or (v) through brokerage platforms of firms that have agreements with ABI to offer such shares when acting solely on an agency basis for the purchase or sale of such shares. Generally, a fee-based program must charge an asset-based or other similar fee and must invest at least $250,000 in Advisor Class shares of a Fund in order to be approved by ABI for investment in Advisor Class shares. A commission or other transaction fee may be charged by your financial intermediary with respect to the purchase, sale or exchange of Advisor Class shares made through such financial intermediary.

Advisor Class shares are not subject to an initial sales charge, CDSC or distribution services fees, and thus have a lower expense ratio and pay correspondingly higher dividends than Class A, Class C, Class 1, Class R or Class K shares.

Alternative Purchase Arrangements – Group Retirement Plans and Tax-Deferred Accounts

Each Fund, except for Municipal Bond Inflation Strategy, offers special distribution arrangements for Group Retirement Plans. However, plan sponsors, plan fiduciaries and other financial intermediaries may establish requirements as to the purchase, sale or exchange of shares of the Fund, including maximum and minimum initial investment requirements, that are different from those described in this SAI. Group Retirement Plans also may not offer all classes of shares of the Fund. In addition, the Class A CDSC may be waived for investments made through certain Group Retirement Plans. Therefore, plan sponsors or fiduciaries may not adhere to these share class eligibility standards as set forth in the Prospectus and this SAI. The Fund is not responsible for, and has no control over, the decision of any plan sponsor or fiduciary to impose such differing requirements.

Class A Shares. Class A shares are available at NAV to Group Retirement Plans, regardless of size, and to the AllianceBernstein Link, AllianceBernstein Individual 401(k) and AllianceBernstein SIMPLE IRA plans with at least $250,000 in plan assets or 100 or more employees. Effective June 30, 2005, for purposes of determining whether a SIMPLE IRA plan has at least $250,000 in plan assets, all of the SIMPLE IRAs of an employer’s employees are aggregated. ABI measures the asset levels and number of employees in these plans once monthly. Therefore, if a plan that is not eligible at the beginning of a month for purchases of Class A shares at NAV meets the asset level or number of employees required for such eligibility, later in that month all purchases by the plan will be subject to a sales charge until the monthly measurement of assets and employees. If the plan terminates a Fund as an investment option within one year (18 months for Bond Inflation Strategy), then all plan purchases of Class A shares will be subject to a 1%, 1-year or 18-month CDSC on redemption. Class A shares are also available at NAV to Group Retirement Plans. The 1%, 1-year or 18-month CDSC also generally applies. However, the 1%, 1-year or 18-month CDSC may be waived if the financial intermediary agrees to waive all commissions or other compensation paid in connection with the sale of such shares (typically up to a 1% advance payment for sales of Class A shares at NAV) other than the service fee paid pursuant to the Company’s distribution services plan.

Class C Shares. Class C shares are available to AllianceBernstein Link, AllianceBernstein Individual 401(k) and AllianceBernstein SIMPLE IRA plans with less than $250,000 in plan assets and less than 100 employees. If an AllianceBernstein Link, AllianceBernstein Individual 401(k) or AllianceBernstein SIMPLE IRA plan holding Class C shares becomes eligible to purchase Class A shares at NAV, the plan sponsor or other appropriate fiduciary of such plan may request ABI in writing to liquidate the Class C shares and purchase Class A shares with the liquidation proceeds. Any such liquidation and repurchase may not occur before the expiration of the 1-year period that begins on the date of the plan’s last purchase of Class C shares.

Class R Shares. Class R shares are available to certain Group Retirement Plans. Class R shares are not subject to an initial sales charge or CDSC, but are subject to a .50% distribution services fee.

Class K Shares. Class K shares are available to certain Group Retirement Plans. Class K shares are not subject to an initial sales charge or CDSC, but are subject to a .25% distribution services fee.

Class I Shares. Class I shares are available to certain Group Retirement Plans. Class I shares generally are not available to retail non-retirement accounts, traditional and ROTH IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs, individual 403(b) plans and AllianceBernstein-sponsored retirement programs known as the “Informed Choice” programs. Class I shares are not subject to an initial sales charge, CDSC or a distribution services fee.

Class Z Shares. Class Z shares are available to certain Group Retirement Plans. Class Z shares generally are not available to traditional and ROTH IRAs, Coverdell Education Savings Accounts, SEPs, SAR-SEPs, SIMPLE IRAs and individual 403(b) plans. Class Z shares are not currently available to Group Retirement Plans in the AllianceBernstein-sponsored programs known as the “Informed Choice” programs. Class Z shares are not subject to an initial sales charge, CDSCs or distribution services fees.

Choosing a Class of Shares for Group Retirement Plans. Plan sponsors, plan fiduciaries and other financial intermediaries may establish requirements as to the purchase, sale or exchange of shares of a Fund, including maximum and minimum initial investment requirements, that are different from those described in this SAI. Plan fiduciaries should consider how these requirements differ from the Fund’s share class eligibility criteria before determining whether to invest.

Currently, each Fund makes its Class A shares available at NAV to Group Retirement Plans. Unless waived under the circumstances described above, a 1%, 1-year CDSC applies to the sale of Class A shares by a plan. Because Class K shares have no CDSC and lower Rule 12b-1 distribution services fees and Class I shares and Class Z shares have no CDSC or Rule 12b-1 distribution services fees, plans should consider purchasing Class K, Class I or Class Z shares, if eligible, rather than Class A shares.

In selecting among the Class A, Class K and Class R shares, plans purchasing shares through a financial intermediary that is not willing to waive advance commission payments (and therefore are not eligible for the waiver of the 1%, 1-year CDSC applicable to Class A shares) should weigh the following:

Because Class A and Class K shares have lower Rule 12b-1 distribution services fees than Class R shares, plans should consider purchasing Class A or Class K shares, if eligible, rather than Class R shares.

Sales Charge Reduction Programs for Class A Shares

The AB Mutual Funds offer shareholders various programs through which shareholders may obtain reduced sales charges or reductions in CDSC through participation in such programs. In order for shareholders to take advantage of the reductions available through the combined purchase privilege, rights of accumulation and letters of intent, a Fund must be notified by the shareholder or his or her financial intermediary that they qualify for such a reduction. If a Fund is not notified that a shareholder is eligible for these reductions, that Fund will be unable to ensure that the reduction is applied to the shareholder’s account.

Combined Purchase Privilege. Shareholders may qualify for the sales charge reductions by combining purchases of shares of a Fund (or any other AB Mutual Fund) into a single “purchase”. By combining such purchases, shareholders may be able to take advantage of the quantity discounts described under “Alternative Purchase Arrangements”. A “purchase” means a single purchase or concurrent purchases of shares of the Fund or any other AB Mutual Fund, by (i) an individual, his or her spouse or domestic partner, or the individual’s children under the age of 21 years purchasing shares for his, her or their own account(s); (ii) a trustee or other fiduciary purchasing shares for a single trust, estate or single fiduciary account with one or more beneficiaries involved; or (iii) the employee benefit plans of a single employer. The term “purchase” also includes purchases by any “company”, as the term is defined in the 1940 Act, but does not include purchases by any such company that has not been in existence for at least six months or that has no purpose other than the purchase of shares of the Fund or shares of other registered investment companies at a discount. The term “purchase” does not include purchases by any group of individuals whose sole organizational nexus is that the participants therein are credit card holders of a company, policy holders of an insurance company, customers of either a bank or broker-dealer or clients of an investment adviser.

Cumulative Quantity Discount (Right of Accumulation). An investor’s purchase of additional Class A shares of a Fund may be combined with the value of the shareholder’s existing accounts, thereby enabling the shareholder to take advantage of the quantity discounts described under “Alternative Purchase Arrangements”. In such cases, the applicable sales charge on the newly purchased shares will be based on the total of:

The initial sales charge you pay on each purchase of Class A shares will take into account your accumulated holdings in all classes of shares of AB Mutual Funds. Your accumulated holdings will be calculated as (a) the value of your existing holdings as of the day prior to your additional investment or (b) the amount you have invested including reinvested dividends but excluding appreciation and less any amount of withdrawals, whichever is higher.

For example, if an investor owned shares of an AB Mutual Fund that were purchased for $200,000 and were worth $190,000 at their then current NAV and, subsequently, purchased Class A shares of a Fund worth an additional $100,000, the initial sales charge for the $100,000 purchase would be at the 2.25% rate applicable to a single $300,000 purchase of shares of the Fund, rather than the 3.25% rate.

Letter of Intent. Class A investors may also obtain the quantity discounts described under “Alternative Purchase Arrangements” by means of a written Letter of Intent, which expresses the investor’s intention to invest at least $100,000 in Class A shares of a Fund or any AB Mutual Fund within 13 months. Each purchase of shares under a Letter of Intent will be made at the public offering price or prices applicable at the time of such purchase to a single transaction of the dollar amount indicated in the Letter of Intent.

Investors qualifying for the Combined Purchase Privilege described above may purchase shares of the AB Mutual Funds under a single Letter of Intent. The AB Mutual Funds will use the higher of cost or current NAV of the investor’s existing investments and of those accounts with which investments are combined via Combined Purchase Privileges toward the fulfillment of the Letter of Intent. For example, if at the time an investor signs a Letter of Intent to invest at least $100,000 in Class A shares of the Fund, the investor and the investor’s spouse or domestic partner each purchase shares of the Fund worth $20,000 (for a total of $40,000), but the current NAV of all applicable accounts is $45,000 at the time a $100,000 Letter of Intent is initiated, it will only be necessary to invest a total of $55,000 during the following 13 months in shares of the AB Mutual Fund to qualify for the reduced sales charge applicable to an investment of $100,000.

The Letter of Intent is not a binding obligation upon the investor to purchase the full amount indicated. The minimum initial investment under a Letter of Intent is 5% of such

amount. Shares purchased with the first 5% of such amount will be held in escrow (while remaining registered in the name of the investor) to secure payment of the higher sales charge applicable to the shares actually purchased if the full amount indicated is not purchased, and such escrowed shares will be involuntarily redeemed at their then NAV to pay the additional sales charge, if necessary. Dividends on escrowed shares, whether paid in cash or reinvested in additional Fund shares, are not subject to escrow. When the full amount indicated has been purchased, the escrow will be released.

Investors wishing to enter into a Letter of Intent in conjunction with their initial investment in Class A shares of a Fund can obtain a form of Letter of Intent by contacting ABIS at the address or telephone numbers shown on the cover of this SAI.

Reinstatement Privilege. A shareholder who has redeemed any or all of his or her Class A shares may reinvest all or any portion of the proceeds from that redemption in Class A shares of any AB Mutual Fund at NAV without any sales charge, provided that such reinvestment is made within 120 calendar days after the redemption or repurchase date. Shares are sold to a reinvesting shareholder at the NAV next-determined as described above. A reinstatement pursuant to this privilege will not cancel the redemption or repurchase transaction; therefore, any gain or loss so realized will be recognized for federal income tax purposes except that no loss will be recognized to the extent that the proceeds are reinvested in shares of the Fund within 30 calendar days after the redemption or repurchase transaction. Investors may exercise the reinstatement privilege by written request sent to the Fund at the address shown on the cover of this SAI.

Dividend Reinvestment Program. Under a Fund’s Dividend Reinvestment Program, unless you specify otherwise, your dividends and distributions will be automatically reinvested in the same class of shares of the Fund without an initial sales charge or CDSC. If you elect to receive your distributions in cash, you will only receive a check if the distribution is equal to or exceeds $25.00. Distributions of less than $25.00 will automatically be reinvested in Fund shares. To receive distributions of less than $25.00 in cash, you must have bank instructions associated to your account so that distributions can be delivered to you electronically via Electronic Funds Transfer using the Automated Clearing House or “ACH”. If you elect to receive distributions by check, your distributions and all subsequent distributions may nonetheless be reinvested in additional shares of the Fund under the following circumstances:

(a) the postal service is unable to deliver your checks to your address of record and the checks are returned to the Fund’s transfer agent as undeliverable; or

(b) your checks remain uncashed for nine months.

Additional shares of the Fund will be purchased at the then current NAV. You should contact the Fund’s transfer agent to change your distribution option. Your request to do so must be received by the transfer agent before the record date for a distribution in order to be effective for that distribution. No interest will accrue on amounts represented by uncashed distribution checks.

Dividend Direction Plan. A shareholder who already maintains accounts in more than one AB Mutual Fund may direct that income dividends and/or capital gains paid by one AB Mutual Fund be automatically reinvested, in any amount, without the payment of any sales or

service charges, in shares of any eligible class of one or more other AB Mutual Fund(s) in which the shareholder maintains an account. Further information can be obtained by contacting ABIS at the address or the “For Literature” telephone number shown on the cover of this SAI. Investors wishing to establish a dividend direction plan in connection with their initial investment should complete the appropriate section of the Mutual Fund Application found in your Prospectus. Current shareholders should contact ABIS to establish a dividend direction plan.

Systematic Withdrawal Plan

General. Any shareholder who owns or purchases shares of a Fund having a current NAV of at least $5,000 may establish a systematic withdrawal plan under which the shareholder will periodically receive a payment in a stated amount of not less than $50 on a selected date. The $5,000 account minimum does not apply to a shareholder owning shares through an individual retirement account or other retirement plan who has attained the age of 73 who wishes to establish a systematic withdrawal plan to help satisfy a required minimum distribution. For Class 1 and Class 2 shares, a systematic withdrawal plan is available only to shareholders who own book-entry shares worth $25,000 or more. Systematic withdrawal plan participants must elect to have their dividends and distributions from the Fund automatically reinvested in additional shares of the Fund.

Shares of a Fund owned by a participant in the Fund’s systematic withdrawal plan will be redeemed as necessary to meet withdrawal payments and such payments will be subject to any taxes applicable to redemptions and, except as discussed below with respect to Class A and Class C shares, any applicable CDSC. Shares acquired with reinvested dividends and distributions will be liquidated first to provide such withdrawal payments and thereafter other shares will be liquidated to the extent necessary, and depending upon the amount withdrawn, the investor’s principal may be depleted. A systematic withdrawal plan may be terminated at any time by the shareholder or the Fund.

Withdrawal payments will not automatically end when a shareholder’s account reaches a certain minimum level. Therefore, redemptions of shares under the plan may reduce or even liquidate a shareholder’s account and may subject the shareholder to a Fund’s involuntary redemption provisions. See “Redemption and Repurchase of Shares—General”. Purchases of additional shares concurrently with withdrawals are undesirable because of sales charges applicable when purchases are made. While an occasional lump-sum investment may be made by a holder of Class A shares who is maintaining a systematic withdrawal plan, such investment should normally be an amount equivalent to three times the annual withdrawal or $5,000, whichever is less.

Payments under a systematic withdrawal plan may be made by check or electronically via the ACH network. Investors wishing to establish a systematic withdrawal plan in conjunction with their initial investment in shares of a Fund should complete the appropriate portion of the Mutual Fund Application, while current Fund shareholders desiring to do so can obtain an application form by contacting ABIS at the address or the “For Literature” telephone number shown on the cover of this SAI.

CDSC Waiver for Class A Shares and Class C Shares. Under the systematic withdrawal plan, up to 1% monthly, 2% bi-monthly or 3% quarterly of the value at the time of

redemption of the Class A or Class C shares in a shareholder’s account may be redeemed free of any CDSC.

With respect to Class A and Class C shares, shares held the longest will be redeemed first and will count toward the foregoing limitations. Redemptions in excess of those limitations will be subject to any otherwise applicable CDSC.

Payments to Financial Advisors and Their Firms

Financial intermediaries market and sell shares of a Fund. These financial intermediaries employ financial advisors and receive compensation for selling shares of the Funds. This compensation is paid from various sources, including any sales charge, CDSC and/or Rule 12b-1 fee that you or the Funds may pay. Your individual financial advisor may receive some or all of the amounts paid to the financial intermediary that employs him or her.

In the case of Class A shares, all or a portion of the initial sales charge that you pay is paid by ABI to financial intermediaries selling Class A shares. ABI also pays these financial intermediaries a fee of up to 1% on purchases of $1 million or more. Additionally, up to 100% of the Rule 12b-1 fees applicable to Class A shares each year may be paid to financial intermediaries, including your financial intermediary, that sell Class A shares.

In the case of Class C shares, ABI pays, at the time of your purchase, a commission to firms selling Class C shares in an amount equal to 1% of your investment. Additionally, up to 100% of the Rule 12b-1 fee applicable to Class C shares each year may be paid to financial intermediaries, including your financial intermediary, that sell Class C shares.

In the case of Class 1 shares up to 100% of the Rule 12b-1 fee applicable to Class 1 shares each year may be paid to financial intermediaries, including your financial intermediary, that sell Class 1 shares.

In the case of Class R and Class K shares up to 100% of the Rule 12b-1 fee applicable to Class R and Class K shares each year may be paid to financial intermediaries, including your financial intermediary, that sell Class R and Class K shares.

In the case of Advisor Class shares, your financial intermediary may charge ongoing fees or transactional fees. ABI may pay a portion of “ticket” or other transactional charges.

Your financial advisor’s firm receives compensation from the Funds, ABI and/or the Adviser in several ways from various sources, which include some or all of the following:

Please read your Prospectus carefully for information on this compensation. Please also refer to Appendix C—Financial Intermediary Waivers in the Prospectus.

Other Payments for Distribution Services and Educational Support

In addition to the commissions paid to or charged by financial intermediaries at the time of sale and the fees described under “Asset-Based Sales Charges or Distribution and/or Service (Rule 12b-1) Fees”, in your Prospectus, some or all of which are paid to financial intermediaries (and, in turn, may be paid to your financial advisor), ABI, at its expense, currently provides additional payments to firms that sell shares of the AB Mutual Funds. The Adviser and its affiliates, at their own expense, provide similar payments to firms for providing distribution, marketing, promotional, educational and other services to the AB ETFs. Although the individual components may be higher and the total amount of payments made to each qualifying firm in any given year may vary, the total amount paid to a financial intermediary in connection with the services and the sale of shares of the AB Funds will generally not exceed the sum of (a) 0.25% of the current year’s fund sales by that firm and (b) 0.10% of average daily net assets attributable to that firm over the year. These sums include payments for distribution and analytical data pertaining to AB Funds by financial advisors of these firms and to reimburse directly or indirectly the costs incurred by these firms and their employees in connection with educational seminars and training efforts about the AB Funds for the firms’ employees and/or their clients and potential clients. The costs and expenses associated with these efforts may include travel, lodging, entertainment and meals.

For 2024, the Adviser and ABI and their affiliates expect to pay approximately 0.04% of the average monthly assets of the AB Funds, or approximately $26 million, for distribution services and education support related to the AB Funds. For 2023, the Adviser and ABI and their affiliates estimate that they will have paid approximately 0.04% of the average monthly assets of the AB Funds or approximately $25 million for distribution services and educational support related to the AB Funds.

A number of factors are considered in determining the additional payments, including each firm’s AB Fund sales, assets and redemption rates, and the willingness and ability of the firm to give the Adviser and ABI and their affiliates access to its financial advisors for educational and marketing purposes. In some cases, firms will include the AB Funds on a “preferred list”. The goal is to make the financial advisors who interact with current and prospective investors and shareholders more knowledgeable about the AB Funds so that they can provide suitable information and advice about the funds and related investor services.

The Funds and ABI also make payments for recordkeeping and other transfer agency services to financial intermediaries that sell AB Fund shares. Please see “Expenses of the Funds – Transfer Agency Agreement” above. These expenses paid by a Fund are included in “Other Expenses” under “Fees and Expenses of the Fund – Annual Fund Operating Expenses” in your Prospectus.

If one mutual fund sponsor makes greater distribution assistance payments than another, your financial advisor and his or her firm may have an incentive to recommend one fund complex over another. Similarly, if your financial advisor or his or her firm receives more distribution assistance for one share class versus another, then they may have an incentive to recommend that class.

Please speak with your financial advisor to learn more about the total amounts paid to your financial advisor and his or her firm by the Funds, the Adviser, ABI and by sponsors of other mutual funds he or she may recommend to you. You should also consult disclosures made by your financial advisor at the time of purchase.

ABI anticipates that the firms that will receive additional payments for distribution services and/or educational support include:

Although the Funds may use brokers and dealers that sell shares of the Funds to effect portfolio transactions, the Funds do not consider the sale of AB Fund shares as a factor when selecting brokers or dealers to effect portfolio transactions.

The following information supplements that set forth in your Prospectus under the heading “Investing in the Funds”. If you are an Advisor Class shareholder through an account established under a fee-based program or commission-based brokerage program, your program may impose requirements with respect to the purchase, sale or exchange of Advisor Class shares of a Fund that are different from those described herein. A commission or other transaction fee may be charged by your financial intermediary with respect to the purchase, sale or exchange of Advisor Class shares made through such financial intermediary. Similarly, if you are a shareholder through a Group Retirement Plan, your plan may impose requirements with respect to the purchase, sale or exchange of shares of a Fund that are different from those imposed below.

Each Fund has authorized one or more brokers to receive on its behalf purchase and redemption orders. Such brokers are authorized to designate other intermediaries to receive purchase and redemption orders on the Fund’s behalf. In such cases, orders will receive the NAV next computed after such order is properly received by the authorized broker or designee and accepted by the Fund.

Redemption

Subject only to the limitations described below, each Fund will redeem the shares tendered to it, as described below, at a redemption price equal to their NAV as next computed following the receipt of shares tendered for redemption in proper form. Except for any CDSC which may be applicable to Class A or Class C shares, there is no redemption charge. A Fund expects that it will typically take one to three business days following the receipt of a shareholder’s redemption request in proper form to pay out redemption proceeds. However, while not expected, payment of redemption proceeds may take up to seven days after the day it is received in proper form by the Fund by the Fund Closing Time. If a shareholder is in doubt about what documents are required by his or her investment program or employee benefit plan, the shareholder should contact his or her financial intermediary.

The right of redemption may not be suspended or the date of payment upon redemption postponed for more than seven days after shares are tendered for redemption, except for any period during which the Exchange is closed (other than customary weekend and holiday closings) or during which the Commission determines that trading thereon is restricted, or for any period during which an emergency (as determined by the Commission) exists as a result of which disposal by a Fund of securities owned by it is not reasonably practicable or as a result of which it is not reasonably practicable for the Fund fairly to determine the value of its net assets, or for such other periods as the Commission may by order permit for the protection of security holders of the Fund.

A Fund may, but is not obligated to, temporarily delay the disbursement of redemption proceeds from an account held directly with the Fund by a Specified Adult (as defined below) if there is a reasonable belief that financial exploitation of the Specified Adult has occurred, is occurring, has been attempted, or will be attempted. The Fund will provide notice of this temporary delay, and it will be for an initial period of no more than 15 business days while

the Fund conducts an internal review of the facts and circumstances of the suspected financial exploitation. If the internal review supports the Fund’s belief that actual or attempted financial exploitation has occurred or is occurring, the Fund may extend the hold for up to 10 additional business days. Both the initial and additional hold on the disbursement may be terminated or extended by a state regulator or an agency or court of competent jurisdiction. For purposes of this paragraph, the term “Specified Adult” refers to an individual who is (A) a natural person age 65 and older; or (B) a natural person age 18 and older who is reasonably believed to have a mental or physical impairment that renders the individual unable to protect his or her own interests.

Payment of the redemption price normally will be made in cash but may be made, at the option of a Fund, in-kind. No interest will accrue on uncashed redemption checks. The value of a shareholder’s shares on redemption or repurchase may be more or less than the cost of such shares to the shareholder, depending upon the market value of the Fund’s portfolio securities at the time of such redemption or repurchase. Redemption proceeds from Class A and Class C shares will reflect the deduction of the CDSC, if any. Payment received by a shareholder upon redemption or repurchase of his or her shares, assuming the shares constitute capital assets in his or her hands, will result in long-term or short-term capital gain (or loss) depending upon the shareholder’s holding period and basis in respect of the shares redeemed.

To redeem shares of a Fund for which no share certificates have been issued, the registered owner or owners should forward a letter to the Fund containing a request for redemption. The Fund may require the signature or signatures on the letter to be Medallion Signature Guaranteed. Please contact ABIS to confirm whether a Medallion Signature Guarantee is needed.

To redeem shares of a Fund represented by share certificates, the investor should forward the appropriate share certificate or certificates, endorsed in blank or with blank stock powers attached, to the Fund with the request that the shares represented thereby, or a specified portion thereof, be redeemed. The stock assignment form on the reverse side of each share certificate surrendered to the Fund for redemption must be signed by the registered owner or owners exactly as the registered name appears on the face of the certificate or, alternatively, a stock power signed in the same manner may be attached to the share certificate or certificates or, where tender is made by mail, separately mailed to the relevant Fund. The signature or signatures on the assignment form must be guaranteed in the manner described above.

Telephone Redemption by Electronic Funds Transfer. Each Fund shareholder is entitled to request redemption by electronic funds transfer (of shares for which no share certificates have been issued) by telephone at (800) 221-5672 if the shareholder has completed the appropriate portion of the Mutual Fund Application or, if an existing shareholder has not completed this portion, by an “Autosell” application obtained from ABIS (except for certain omnibus accounts). A telephone redemption request by electronic funds transfer may not exceed $100,000, and must be made before the Fund Closing Time, on a Fund business day as defined above. Proceeds of telephone redemptions will be sent by electronic funds transfer to a shareholder’s designated bank account at a bank selected by the shareholder that is a member of NACHA.

Telephone Redemption by Check. Each Fund shareholder is eligible to request redemption by check of Fund shares for which no share certificates have been issued by telephone at (800) 221-5672 before the Fund Closing Time, on a Fund business day in an amount not

exceeding $100,000. Proceeds of such redemptions are remitted by check to the shareholder’s address of record. A shareholder otherwise eligible for telephone redemption by check may cancel the privilege by written instruction to ABIS, or by checking the appropriate box on the Mutual Fund Application.

Telephone Redemptions—General. During periods of drastic economic, market or other developments, such as the terrorist attacks on September 11, 2001, it is possible that shareholders would have difficulty in reaching ABIS by telephone (although no such difficulty was apparent at any time in connection with the attacks). If a shareholder were to experience such difficulty, the shareholder should issue written instructions to ABIS at the address shown on the cover of this SAI. The Fund reserves the right to suspend or terminate its telephone redemption service at any time without notice. Telephone redemption is not available with respect to shares (i) for which certificates have been issued, (ii) held in nominee or “street name” accounts, (iii) held by a shareholder who has changed his or her address of record within the preceding 30 calendar days or (iv) held in any retirement plan account. Neither the Funds, the Adviser, ABI nor ABIS will be responsible for the authenticity of telephone requests for redemptions that a Fund reasonably believes to be genuine. The Fund will employ reasonable procedures in order to verify that telephone requests for redemptions are genuine, including, among others, recording such telephone instructions and causing written confirmations of the resulting transactions to be sent to shareholders. If a Fund did not employ such procedures, it could be liable for losses arising from unauthorized or fraudulent telephone instructions. Financial intermediaries may charge a commission for handling telephone requests for redemptions.

Redemptions Through Intermediaries. A Fund may redeem shares through ABI or financial intermediaries. The redemption price will be the NAV next determined after ABI receives the request (less the CDSC, if any, with respect to the Class A and Class C shares), except that requests placed through financial intermediaries before the Fund Closing Time will be executed at the NAV determined as of the Fund Closing Time on that day. Neither the Funds nor ABI charges a fee or commission in connection with the redemption of shares (except for the CDSC, if any, with respect to Class A and Class C shares). Normally, if shares of a Fund are offered through a financial intermediary, the redemption is settled by the shareholder as an ordinary transaction with or through that financial intermediary, who may charge the shareholder for this service.

Account Closure and Sale

Account Closure. Each Fund reserves the right to close out an account that has remained below $1,000 for 90 days. No CDSC will be deducted from the proceeds of this redemption. In the case of a redemption or repurchase of shares of a Fund recently purchased by check, redemption proceeds will not be made available until the Fund is reasonably assured that the check has cleared, normally up to 15 calendar days following the purchase date.

Sale—Class 1 Shares. Under certain circumstances, Bernstein may redeem your Class 1 shares of a Fund without your consent. Maintaining small shareholder accounts is costly. Accordingly, if you make a sale that reduces the value of your account to less than $1,000, we may, on at least 60 days’ prior written notice, sell your remaining Class 1 shares in the Fund and close your account. We will not close your account if you increase your account balance to $1,000 during the 60-day notice period.

Sale—Class 2 Shares. Under certain circumstances, Bernstein may redeem your Class 2 shares of a Fund without your consent. Maintaining small shareholder accounts is costly. Accordingly, if you make a sale that reduces the value of your account to less than $250,000, we may, on at least 60 days’ prior written notice, sell your remaining Class 2 shares in the Fund and close your account. We will not close your account if you increase your account balance to $250,000 during the 60 day notice period.

The following information supplements that set forth in your Prospectus under the heading “Investing in the Funds”. The shareholder services set forth below are applicable to all classes of shares of a Fund unless otherwise indicated.

If you are an Advisor Class shareholder through an account established under a fee-based program or commission-based brokerage program or a shareholder in a Group Retirement Plan, your program or retirement plan may impose requirements with respect to the purchase, sale or exchange of shares of a Fund that are different from those described herein. A commission or other transaction fee may be charged by your financial intermediary with respect to the purchase, sale or exchange of Advisor Class shares made through such intermediary.

Automatic Investment Program

Investors may purchase shares of a Fund through an automatic investment program utilizing electronic funds transfer drawn on the investor’s own bank account. Under such a program, pre-authorized monthly drafts for a fixed amount are used to purchase shares through the financial intermediary designated by the investor at the public offering price next determined after ABI receives the proceeds from the investor’s bank. The monthly drafts must be in minimum amounts of either $50 or $200, depending on the investor’s initial purchase. If an investor makes an initial purchase of at least $2,500, the minimum monthly amount for pre-authorized drafts is $50. If an investor makes an initial purchase of less than $2,500, the minimum monthly amount for pre-authorized drafts is $200 and the investor must commit to a monthly investment of at least $200 until the investor’s account balance is $2,500 or more. In electronic form, drafts can be made on or about a date each month selected by the shareholder. Investors wishing to establish an automatic investment program in connection with their initial investment should complete the appropriate portion of the Mutual Fund Application. Current shareholders should contact ABIS at the address or telephone numbers shown on the cover of this SAI to establish an automatic investment program.

Shareholders committed to monthly investments of $25 or more through the Automatic Investment Program by October 15, 2004 are able to continue their program despite the $50 monthly minimum.

Exchange Privilege

You may exchange your investment in the Funds for shares of the same class of other AB Mutual Funds if the other AB Mutual Fund in which you wish to invest offers shares of

the same class. In addition, (i) present officers and full-time employees of the Adviser, (ii) present Directors or Trustees of any AB Mutual Fund, (iii) certain employee benefit plans for employees of the Adviser, ABI, ABIS and their affiliates and (iv) certain persons participating in a fee-based program, sponsored and maintained by a registered broker-dealer or other financial intermediary and approved by ABI, under which such persons pay an asset-based fee for service in the nature of investment advisory or administrative services may, on a tax-free basis, exchange Class A, Class C, Class R, Class K, Class I, Class Z, Class 1 and Class 2 shares of the Fund for Advisor Class shares of the Fund or Class C shares of the Fund for Class A shares of the Fund. Exchanges of shares are made at the NAV next determined and without sales or service charges. Exchanges may be made by telephone or written request. In order to receive a day’s NAV, ABIS must receive and confirm a telephone exchange request by the Fund Closing Time on that day.

Shares will continue to age without regard to exchanges for purposes of determining the CDSC, if any, upon redemption and, in the case of Class C shares of a Fund, for the purpose of conversion to Class A shares of that Fund. After an exchange, your Class C shares will automatically convert to Class A shares in accordance with the conversion schedule applicable to the Class C shares of the AB Mutual Fund you originally purchased for cash (“original shares”). When redemption occurs, the CDSC applicable to the original shares is applied.

Please read carefully the prospectus of the AB Mutual Fund into which you are exchanging before submitting the request. Call ABIS at (800) 221-5672 to exchange uncertificated shares. Except with respect to exchanges of Class A, Class C, Class R, Class K, Class I, Class Z, Class 1 or Class 2 shares of a Fund for Advisor Class shares or Class C shares for Class A shares of the same Fund, exchanges of shares as described above in this section are taxable transactions for federal income tax purposes. The exchange service may be modified, restricted, or terminated on 60 days’ written notice.

All exchanges are subject to the minimum investment requirements and any other applicable terms set forth in the prospectus for the AB Mutual Fund whose shares are being acquired. An exchange is effected through the redemption of the shares tendered for exchange and the purchase of shares being acquired at their respective NAVs as next determined following receipt by the AB Mutual Fund whose shares are being exchanged of (i) proper instructions and all necessary supporting documents as described in such fund’s prospectus, or (ii) a telephone request for such exchange in accordance with the procedures set forth in the following paragraph. Exchanges of shares of AB Mutual Funds will generally result in the realization of a capital gain or loss for federal income tax purposes.

Each Fund shareholder and the shareholder’s financial intermediary are authorized to make telephone requests for exchanges unless ABIS receives written instruction to the contrary from the shareholder, or the shareholder declines the privilege by checking the appropriate box on the Mutual Fund Application. Such telephone requests cannot be accepted with respect to shares then represented by share certificates. Shares acquired pursuant to a telephone request for exchange will be held under the same account registration as the shares redeemed through such exchange.

Eligible shareholders desiring to make an exchange should telephone ABIS with their account number and other details of the exchange at (800) 221-5672 before the Fund Closing Time, on a Fund business day as defined above. Telephone requests for exchange received before

the Fund Closing Time on the Fund business day will be processed as of the close of business on that day. During periods of drastic economic, market or other developments, it is possible that shareholders would have difficulty in reaching ABIS by telephone (although no such difficulty was apparent at any time in connection with the attacks). If a shareholder were to experience such difficulty, the shareholder should issue written instructions to ABIS at the address shown on the cover of this SAI.

A shareholder may elect to initiate a monthly “Auto Exchange” whereby a specified dollar amount’s worth of his or her Fund shares (minimum $25) is automatically exchanged for shares of another AB Mutual Fund.

None of the AB Mutual Funds, the Adviser, ABI or ABIS will be responsible for the authenticity of telephone requests for exchanges that a Fund reasonably believes to be genuine. Each Fund will employ reasonable procedures in order to verify that telephone requests for exchanges are genuine, including, among others, recording such telephone instructions and causing written confirmations of the resulting transactions to be sent to shareholders. If a Fund did not employ such procedures, it could be liable for losses arising from unauthorized or fraudulent telephone instructions. Financial intermediaries may charge a commission for handling telephone requests for exchanges.

The exchange privilege is available only in states where shares of the AB Mutual Funds being acquired may legally be sold. Each AB Mutual Fund reserves the right, at any time on 60 days’ written notice to its shareholders, to modify, restrict or terminate the exchange privilege.

Statements and Reports

Each Fund transmits to shareholders its semi-annual and annual reports which include a portfolio of investments, financial statements and, in the case of the annual report, the report of the Funds’ independent registered public accounting firm, Ernst & Young LLP, One Manhattan West, New York, NY 10001. In addition, shareholders also receive a confirmation of each purchase and redemption. By contacting his or her financial intermediary or ABIS, a shareholder can arrange for copies of his or her account statements to be sent to another person.

The NAV of each Fund is calculated at the close of regular trading on any day the Exchange is open (ordinarily 4:00 p.m., Eastern time, but sometimes earlier, as in the case of scheduled half-day trading or unscheduled suspensions of trading) following receipt of a purchase or redemption order by a Fund on each Fund business day on which such an order is received and on such other days as the Board deems appropriate or necessary in order to comply with Rule 22c-1 under the 1940 Act. Each Fund’s per share NAV is calculated by dividing the value of the Fund’s total assets, less its liabilities, by the total number of its shares then outstanding. A Fund business day is any weekday on which the Exchange is open for trading.

The following describes the typical methods for valuing investments commonly held by the Funds:

Portfolio securities are valued at market value or, if market quotations are not readily available or are unreliable, at “fair value” as determined in accordance with applicable rules under the 1940 Act and the Funds’ pricing policies and procedures. Pursuant to Rule 2a-5 under the 1940 Act, each Fund’s Board has designated the Adviser as the valuation designee (“Valuation Designee”) with responsibility for performing all fair valuations of each Fund’s portfolio investments, subject to the Board’s oversight. The Adviser has established a valuation committee of senior officers and employees to fulfill the Adviser’s responsibilities as each Fund’s Valuation Designee, which operates under policies and procedures approved by the Fund’s Board to value the Fund’s assets.

Equity securities listed on the Exchange or another national exchange (other than securities listed on NASDAQ), are valued at their last sale prices reflected on the consolidated tape at the close of the exchange. Securities listed and trading on the NASDAQ are valued at the NASDAQ Official Closing Price. If there are no sales on the relevant business day, closing prices provided by the exchange, last trade prices from other exchanges, other trade prices available or fair value methodology may be used to value the securities. OTC equity securities trading on “Pink Sheets” are valued at the mid-level between current bid and asked prices. If mid-prices are not available, securities will be valued at bid prices. The Valuation Designee may fair value international equity securities in Funds that are valued as of 4:00 p.m. Eastern Time. Fair valuing such securities seeks to align closing prices on foreign markets that close prior to 4:00 p.m. Eastern Time with closing prices on U.S. Markets.

Fixed-income instruments are typically valued on the basis of bid prices provided by an approved pricing service when the Valuation Designee reasonably believes that such prices reflect the fair value of the instruments. The market convention may be to use the mid-price between bid and offer in certain markets, and fixed-income instruments may be valued on the basis of the mid-prices when such prices reflect the convention of the particular markets. If the Valuation Designee determines that an appropriate pricing vendor does not exist for a fixed-income instrument, the Valuation Designee may use broker quotations consistent with the manner in which the instruments are quoted and traded, or another valuation methodology deemed reasonable by the Valuation Designee.

The fair value of listed derivatives and OTC derivatives is determined with market models and inputs sourced from market data providers. Fair value is determined based on the terms of the instruments and with inputs as of the valuation date. Indicative broker quotations and/or values provided by counterparties may be used if an instrument is not easily modeled and pricing vendors are not able to price the instrument.

When making a fair value determination, the Adviser may take into account any factors it deems appropriate. The Adviser may determine fair value based upon developments related to a specific security, current valuations of foreign stock indices (as reflected in U.S. futures markets) and/or U.S. sector or broader stock market indices. The prices of securities used to calculate NAV may differ from quoted or published prices for the same securities. Making a fair value determination involves subjective judgments, and it is possible that the fair value determined for a security is materially different than the value that could be realized upon the sale of that security.

Each Fund expects to use fair value pricing for securities primarily traded on U.S. exchanges under certain circumstances, such as the early closing of the exchange on which a

security is traded or suspension of trading in the security, or for securities for which market prices are not readily available or deemed unreliable (including restricted securities). Each Fund uses fair value pricing routinely for securities primarily traded in non-U.S. markets because, among other things, most foreign markets close well before each Fund ordinarily values its securities at 4:00 p.m., Eastern Time. The earlier close of these foreign markets gives rise to the possibility that significant events, including broad market moves, may have occurred in the interim. Factors considered in fair value pricing may include, but are not limited to, interest rates, foreign currency exchange rates, levels of publicly available benchmarks, prices of futures contracts or comparable securities, or information obtained by analysis of the issuers’ financial statements. Because most fixed-income securities are not traded on exchanges, they are primarily valued using fair value prices provided by independent pricing services when the Valuation Designee reasonably believes that such prices reflect the fair value of the instruments.

Each Fund’s Board may suspend the determination of a Fund’s NAV (and the offering and sale of shares), subject to the rules of the Commission and other governmental rules and regulations, at a time when: (1) the Exchange is closed, other than customary weekend and holiday closings, (2) an emergency exists as a result of which it is not reasonably practicable for the Fund to dispose of securities owned by it or to determine fairly the value of its net assets or (3) for the protection of shareholders, if the Commission by order permits a suspension of the right of redemption or a postponement of the date of payment on redemption.

For purposes of determining a Fund’s NAV per share, all assets and liabilities initially expressed in a foreign currency will be converted into U.S. Dollars at the mean of the current bid and asked prices of such currency against the U.S. Dollar last quoted by a major bank that is a regular participant in the relevant foreign exchange market or on the basis of a pricing service that takes into account the quotes provided by a number of such major banks. If such quotations are not available as of the close of the Exchange, the rate of exchange will be determined in good faith by, or under the direction of, the Board.

The assets attributable to the Class A shares, Class C shares, Class 1 shares, Class 2 shares, Class R shares, Class K shares, Class I shares and Advisor Class shares are invested together in a single portfolio. The NAV of each class is determined separately by subtracting the liabilities allocated to that class from the assets belonging to that class in conformance with the provisions of plans adopted by the Funds in accordance with Rule 18f-3 under the 1940 Act.

Dividends paid by a Fund, if any, with respect to Class A, Class C, Class R, Class K, Class I, Class Z, Advisor Class, Class 1 and Class 2 shares will be calculated in the same manner at the same time on the same day and will be in the same amount, except that the higher distribution services fees applicable to Class C shares will be borne exclusively by the class to which they relate.

The following summary addresses only the principal United States federal income tax considerations pertinent to the Funds and to shareholders of the Funds. This summary does not address the United States federal income tax consequences of owning shares to all categories

of investors, some of which may be subject to special rules. This summary is based upon the advice of counsel for the Funds and upon current law and interpretations thereof. No confirmation has been obtained from the relevant tax authorities. There is no assurance that the applicable laws and interpretations will not change.

In view of the individual nature of tax consequences, each shareholder is advised to consult the shareholder’s own tax adviser with respect to the specific tax consequences of being a shareholder of the Funds, including the effect and applicability of federal, state, local, foreign and other tax laws and the effects of changes therein.

General

Each Fund intends for each taxable year to qualify to be taxed as a “regulated investment company” under the Code. To so qualify, a Fund must, among other things, (i) derive at least 90% of its gross income in each taxable year from dividends, interest, payments with respect to securities loans, gains from the sale or other disposition of stock, securities or foreign currency, certain other income (including, but not limited to, gains from options, futures or forward contracts) derived with respect to its business of investing in stock, securities or currency or net income derived from interests in certain “qualified publicly traded partnerships”; and (ii) diversify its holdings so that, at the end of each quarter of its taxable year, the following two conditions are met: (a) at least 50% of the value of the Fund’s assets is represented by cash, cash items, U.S. Government securities, securities of other regulated investment companies and other securities with respect to which the Fund’s investment is limited, in respect of any one issuer, to an amount not greater than 5% of the value of the Fund’s assets and to not more than 10% of the outstanding voting securities of such issuer and (b) not more than 25% of the value of the Fund’s assets is invested in securities of any one issuer (other than U.S. Government securities or securities of other regulated investment companies), or securities (other than securities of other regulated investment companies) of any two or more issuers which the Fund controls and which are engaged in the same or similar trades or businesses or related trades or businesses, or securities of one or more “qualified publicly traded partnerships”.

If a Fund qualifies as a regulated investment company for any taxable year and makes timely distributions to its shareholders of 90% or more of its investment company taxable income for that year (calculated without regard to its net capital gain, i.e., the excess of its net long-term capital gain over its net short-term capital loss) it will not be subject to federal income tax on the portion of its taxable income for the year (including any net capital gain) that it distributes to shareholders.

Each Fund will also avoid the 4% federal excise tax that would otherwise apply to certain undistributed income for a given calendar year if it makes timely distributions to the shareholders equal to at least the sum of (i) 98% of its ordinary income for that year, (ii) 98.2% of its capital gain net income and foreign currency gains for the twelve-month period ending on October 31 of that year or, if later during the calendar year, the last day of the Fund’s taxable year (i.e., November 30 or December 31) if the Fund is eligible to so elect and so elects, and (iii) any ordinary income or capital gain net income from the preceding calendar year that was not distributed during that year. For this purpose, income or gain retained by the Fund that is subject to corporate income tax will be considered to have been distributed by the Fund during such year. For federal income and excise tax purposes, dividends declared and payable to shareholders of record as of a date in October, November or December of a given year but actually paid during

the immediately following January will be treated as if paid by the Fund on December 31 of such earlier calendar year, and will be taxable to these shareholders in the year declared, and not in the year in which the shareholders actually receive the dividend.

The information set forth in the Prospectus and the following discussion relate solely to the significant U.S. federal income taxes on dividends and distributions by a Fund and assume that the Fund qualifies to be taxed as a regulated investment company. An investor should consult his or her own tax advisor with respect to the specific tax consequences of being a shareholder in the Fund, including the effect and applicability of federal, state, local and foreign tax laws to his or her own particular situation and the possible effects of changes therein.

Dividends and Distributions

Each Fund intends to make timely distributions of its respective taxable income (including any net capital gain) so that it will not be subject to federal income or excise taxes. Dividends of each Fund’s net ordinary income and distributions of any net realized short-term capital gain will generally be taxable to shareholders as ordinary income. In the case of corporate shareholders, such dividends may be eligible for the dividends-received deduction, except that the amount eligible for the deduction is limited to the amount of qualifying dividends received by the relevant Fund. For information about Municipal Bond Inflation Strategy distributions, see “U.S. Federal Income Taxation of the Municipal Bond Inflation Strategy” below.

Some or all of the distributions from a Fund may be treated as “qualified dividend income”, taxable to individuals, trusts and estates at the reduced tax rates applicable to long-term capital gains. A distribution from a Fund will be treated as qualified dividend income to the extent that it is comprised of dividend income received by the Fund from taxable domestic corporations and certain qualified foreign corporations, and provided that the Fund meets certain holding period and other requirements with respect to the security with respect to which the dividend is paid. In addition, the shareholder must meet certain holding period requirements with respect to the shares of the Fund in order to take advantage of this preferential tax rate. To the extent distributions from the Fund are attributable to other sources, such as taxable interest or short-term capital gains, dividends paid by the Fund will not be eligible for the lower rates. The Fund will notify shareholders as to how much of the Fund’s distributions, if any, would qualify for the reduced tax rate, assuming that the shareholder also satisfies the holding period requirements.

Distributions of net capital gain are taxable as long-term capital gain, regardless of how long a shareholder has held shares in a Fund. Any dividend or distribution received by a shareholder on shares of the Fund will have the effect of reducing the NAV of such shares by the amount of such dividend or distribution. Furthermore, a dividend or distribution made shortly after the purchase of such shares by a shareholder, although in effect a return of capital to that particular shareholder, would be taxable to him or her as described above. Dividends are taxable in the manner discussed regardless of whether they are paid to the shareholder in cash or are reinvested in additional shares of the Fund.

Income dividends generally are declared and paid monthly, except with respect to All Market Real Return Portfolio, which generally declares and pays annually; capital gains distributions generally occur annually in December. After the end of the calendar year, a Fund

will notify shareholders of the federal income tax status of any distributions made by the Fund to shareholders during such year.

Sales and Redemptions. Any gain or loss arising from a sale or redemption of Fund shares generally will be capital gain or loss if the Fund shares are held as a capital asset, and will be long-term capital gain or loss if the shareholder has held such shares for more than one year at the time of the sale or redemption; otherwise it will be short-term capital gain or loss. If a shareholder has held shares in a Fund for six months or less and during that period has received a distribution of net capital gain, any loss recognized by the shareholder on the sale of those shares during the six-month period will be treated as a long-term capital loss to the extent of the distribution. In determining the holding period of such shares for this purpose, any period during which a shareholder’s risk of loss is offset by means of options, short sales or similar transactions is not counted.

Any loss realized by a shareholder on a sale or exchange of shares of a Fund will be disallowed to the extent the shares disposed of are reacquired within a period of 61 days beginning 30 days before and ending 30 days after the shares are sold or exchanged. For this purpose, acquisitions pursuant to the Dividend Reinvestment Plan would constitute a reacquisition if made within the period. If a loss is disallowed, then such loss will be reflected in an upward adjustment to the basis of the shares acquired.

Cost Basis Reporting. As part of the Energy Improvement and Extension Act of 2008, mutual funds are required to report to the IRS the “cost basis” of shares acquired by a shareholder on or after January 1, 2012 (“covered shares”) and subsequently redeemed. These requirements do not apply to investments through a tax-deferred arrangement, such as a 401(k) plan or an individual retirement plan. The “cost basis” of a share is generally its purchase price adjusted for dividends, return of capital, and other corporate actions. Cost basis is used to determine whether a sale of the shares results in a gain or loss. The amount of gain or loss recognized by a shareholder on the sale or redemption of shares is generally the difference between the cost basis of such shares and their sale price. If you redeem covered shares during any year, then the Funds will report the cost basis of such covered shares to the IRS and you on Form 1099-B along with the gross proceeds received on the redemption, the gain or loss realized on such redemption and the holding period of the redeemed shares.

Your cost basis in your covered shares is permitted to be calculated using any one of three alternative methods: Average Cost, First In-First Out (FIFO) and Specific Share Identification. You may elect which method you want to use by notifying the Funds. This election may be revoked or changed by you at any time up to the date of your first redemption of covered shares. If you do not affirmatively elect a cost basis method then the Funds’ default cost basis calculation method, which is currently the Average Cost method, will be applied to your account(s). The default method will also be applied to all new accounts established unless otherwise requested.

If you hold the Funds’ shares through a broker (or another nominee), please contact that broker (nominee) with respect to the reporting of cost basis and available elections for your account.

You are encouraged to consult your tax advisor regarding the application of the new cost basis reporting rules and, in particular, which cost basis calculation method you should elect.

Tax Qualified Plans. A dividend or capital gains distribution with respect to shares of a Fund held by a tax-deferred or qualified plan, such as an individual retirement account, 403(b)(7) retirement account or corporate pension or profit-sharing plan, generally will not be taxable to the plan. Distributions from such plans will be taxable to individual participants under applicable tax rules without regard to the character of the income earned by the qualified plan.

Backup Withholding. Any distributions and redemption proceeds payable to a shareholder may be subject to “backup withholding” tax (at a rate of 24%) if such shareholder fails to provide the relevant Fund with his or her correct taxpayer identification number, fails to make required certifications, or is notified by the IRS that he or she is subject to backup withholding. Corporate shareholders and certain other shareholders specified in the Code are exempt from such backup withholding. Backup withholding is not an additional tax; any amounts so withheld may be credited against a shareholder’s U.S. federal income tax liability or refunded by filing a refund claim with the IRS, provided that the required information is furnished to the IRS.

Tax Straddles. Any option, futures contract, interest rate swap, cap or floor, or other position entered into or held by a Fund in conjunction with any other position held by the Fund may constitute a “straddle” for federal income tax purposes. A straddle of which at least one, but not all, the positions are section 1256 contracts may constitute a “mixed straddle”. In general, straddles are subject to certain rules that may affect the character and timing of the Fund’s gains and losses with respect to straddle positions by requiring, among other things, that (i) loss realized on disposition of one position of a straddle not be recognized to the extent that the Fund has unrealized gains with respect to the other position in such straddle; (ii) the Fund’s holding period in straddle positions be suspended while the straddle exists (possibly resulting in gain being treated as short-term capital gain rather than long-term capital gain); (iii) losses recognized with respect to certain straddle positions which are part of a mixed straddle and which are non-section 1256 positions be treated as 60% long-term and 40% short-term capital loss; (iv) losses recognized with respect to certain straddle positions which would otherwise constitute short-term capital losses be treated as long-term capital losses; and (v) the deduction of interest and carrying charges attributable to certain straddle positions may be deferred. Various elections are available to the Fund which may mitigate the effects of the straddle rules, particularly with respect to mixed straddles. In general, the straddle rules described above do not apply to any straddles held by the Fund all of the offsetting positions of which consist of section 1256 contracts.

Currency Fluctuations — “Section 988” Gains or Losses. Under the Code, gains or losses attributable to fluctuations in exchange rates which occur between the time Bond Inflation Strategy or All Market Real Return Portfolio accrues interest or other receivables or accrues expenses or other liabilities denominated in a foreign currency and the time the Fund actually collects such receivables or pays such liabilities are treated as ordinary income or ordinary loss. Similarly, gains or losses from the disposition of foreign currencies, from the disposition of debt securities denominated in a foreign currency, or from the disposition of a forward contract denominated in a foreign currency which are attributable to fluctuations in the value of the foreign currency between the date of acquisition of the asset and the date of

disposition also are treated as ordinary income or loss. These gains or losses, referred to under the Code as “section 988” gains or losses, increase or decrease the amount of the Fund’s investment company taxable income available to be distributed to its shareholders as ordinary income, rather than increasing or decreasing the amount of the Fund’s net capital gain. Because section 988 losses reduce the amount of ordinary dividends the Fund will be allowed to distribute for a taxable year, such section 988 losses may result in all or a portion of prior dividend distributions for such year being recharacterized as a non-taxable return of capital to shareholders, rather than as an ordinary dividend, reducing each shareholder’s basis in his or her Fund shares. To the extent that such distributions exceed such shareholder’s basis, each will be treated as a gain from the sale of shares.

Options, Futures Contracts, and Forward Foreign Currency Contracts. Certain listed options, regulated futures contracts, and forward foreign currency contracts are considered “section 1256 contracts” for federal income tax purposes. Section 1256 contracts held by Bond Inflation Strategy or All Market Real Return Portfolio at the end of each taxable year will be “marked to market” and treated for federal income tax purposes as though sold for fair market value on the last business day of such taxable year. Gain or loss realized by the Fund on section 1256 contracts other than forward foreign currency contracts will be considered 60% long-term and 40% short-term capital gain or loss. Gain or loss realized by the Fund on forward foreign currency contracts will be treated as section 988 gain or loss and will therefore be characterized as ordinary income or loss and will increase or decrease the amount of the Fund’s net investment income available to be distributed to shareholders as ordinary income, as described above. The Fund can elect to exempt its section 1256 contracts which are part of a “mixed straddle” (as described below) from the application of section 1256.

Gain or loss realized by a Fund on the lapse or sale of put and call options on foreign currencies which are traded OTC or on certain foreign exchanges will be treated as section 988 gain or loss and will therefore be characterized as ordinary income or loss and will increase or decrease the amount of the Fund’s net investment income available to be distributed to shareholders as ordinary income, as described above. The amount of such gain or loss shall be determined by subtracting the amount paid, if any, for or with respect to the option (including any amount paid by the Fund upon termination of an option written by the Fund) from the amount received, if any, for or with respect to the option (including any amount received by the Fund upon termination of an option held by the Fund). In general, if the Fund exercises such an option on a foreign currency, or if such an option that the Fund has written is exercised, gain or loss on the option will be recognized in the same manner as if the Fund had sold the option (or paid another person to assume the Fund’s obligation to make delivery under the option) on the date on which the option is exercised, for the fair market value of the option. The foregoing rules will also apply to other put and call options which have as their underlying property foreign currency and which are traded OTC or on certain foreign exchanges to the extent gain or loss with respect to such options is attributable to fluctuations in foreign currency exchange rates.

Foreign Income Taxes. Investment income received by the Bond Inflation Strategy and the All Market Real Return Portfolio from sources within foreign countries may be subject to foreign income taxes, including taxes withheld at the source. The United States has entered into tax treaties with many foreign countries which entitle the Funds to a reduced rate of such taxes or exemption from taxes on such income. It is impossible to determine the effective

rate of foreign tax in advance since the amount of the Fund’s assets to be invested within various countries is not known.

If more than 50% of the value of a Fund’s total assets at the close of its taxable year consists of the stock or securities of foreign corporations, the Fund may elect to “pass through” to the Fund’s shareholders the amount of foreign income taxes paid by the Fund. Pursuant to such election, shareholders would be required: (i) to include in gross income (in addition to taxable dividends actually received), their respective pro-rata shares of foreign taxes paid by the Fund; (ii) treat their pro-rata share of such foreign taxes as having been paid by them; and (iii) either to deduct their pro-rata share of foreign taxes in computing their taxable income, or to use it as a foreign tax credit against federal income taxes (but not both). No deduction for foreign taxes could be claimed by a shareholder who does not itemize deductions. In addition, certain shareholders may be subject to rules which limit their ability to fully deduct, or claim a credit for, their pro-rata share of the foreign taxes paid by the Fund. A shareholder’s foreign tax credit with respect to a dividend received from the Fund will be disallowed unless the shareholder holds shares in the Fund on the ex-dividend date and for at least 15 other days during the 30-day period beginning 15 days prior to the ex-dividend date.

Each Fund intends to meet for each fiscal year the requirements of the Code to “pass through” to its shareholders foreign income taxes paid, but there can be no assurance that the Fund will be able to do so. Each shareholder will be notified within 60 days after the close of each taxable year of the Fund whether the foreign taxes paid by the Fund will “pass through” for that year, and, if so, the amount of each shareholder’s pro-rata share (by country) of (i) the foreign taxes paid, and (ii) the Fund’s gross income from foreign sources. Shareholders who are not liable for federal income taxes, such as retirement plans qualified under section 401 of the Code, will not be affected by any such “pass through” of foreign taxes.

The federal income tax status of each year’s distributions by the Fund will be reported to shareholders and to the IRS. The foregoing is only a general description of the treatment of foreign taxes under the U.S. federal income tax laws. Because the availability of a foreign tax credit or deduction will depend on the particular circumstances of each shareholder, potential investors are advised to consult their own tax advisers.

Passive Foreign Investment Companies. If Bond Inflation Strategy or All Market Real Return Portfolio owns shares in a foreign corporation that constitutes a “passive foreign investment company” (a “PFIC”) for federal income tax purposes and the Fund does not elect or is unable to elect to either treat such foreign corporation as a “qualified electing fund” within the meaning of the Code or “mark-to-market” the stock of such foreign corporation, the Fund may be subject to U.S. federal income taxation on a portion of any “excess distribution” it receives from the PFIC or any gain it derives from the disposition of such shares, even if such income is distributed as a taxable dividend by the Fund to its shareholders. The Fund may also be subject to additional interest charges in respect of deferred taxes arising from such distributions or gains. Any tax paid by the Fund as a result of its ownership of shares in a PFIC will not give rise to a deduction or credit to the Fund or to any shareholder. A foreign corporation will be treated as a PFIC if, for the taxable year involved, either (i) such foreign corporation derives at least 75% of its gross income from “passive income” (including, but not limited to, interest, dividends, royalties, rents and annuities), or (ii) on average, at least 50% of the value (or adjusted tax basis, if elected) of the assets held by the corporation produce or are held for production of “passive income”. A Fund will generally be permitted to “mark-to-market” stock in a PFIC. If the Fund

makes such an election, the Fund would include in its taxable income each year an amount equal to the excess, if any, of the fair market value of the PFIC stock as of the close of the taxable year over the Fund’s adjusted basis in the PFIC stock. The Fund would be allowed a deduction for the excess, if any, of the adjusted basis of the PFIC stock over the fair market value of the PFIC stock as of the close of the taxable year, but only to the extent of any net mark-to-market gains included in the Fund’s taxable income for prior taxable years. The Fund’s adjusted basis in the PFIC stock would be adjusted to reflect the amounts included in, or deducted from, income under this election. Amounts included in income pursuant to this election, as well as gain realized on the sale or other disposition of the PFIC stock, would be treated as ordinary income. The deductible portion of any mark-to-market loss, as well as loss realized on the sale or other disposition of the PFIC stock to the extent that such loss does not exceed the net mark-to-market gains previously included by the Fund, would be treated as ordinary loss. The Fund generally would not be subject to the deferred tax and interest charge provisions discussed above with respect to PFIC stock for which a mark-to-market election has been made. If the Fund purchases shares in a PFIC and the Fund elects to treat the foreign corporation as a “qualified electing fund” under the Code, the Fund may be required to include in its income each year a portion of the ordinary income and net capital gains of such foreign corporation, even if this income is not distributed to the Fund. Any such income would be subject to the 90% and calendar year distribution requirements described above.

U.S. Federal Income Taxation of the Municipal Bond Inflation Strategy

The following discussion relates to certain significant U.S. federal income tax consequences to the Fund with respect to the determination of its “investment company taxable income” each year. This discussion assumes that the Fund will be taxed as a regulated investment company for each of its taxable years.

Distributions to shareholders out of tax-exempt interest income earned by the Fund is not subject to federal income tax if, at the close of each quarter of such Fund’s taxable year, at least 50% of the value of such Fund’s total assets consists of tax-exempt obligations. The Fund intends to meet this requirement. Insurance proceeds received by the Fund under any insurance policies in respect of scheduled interest payments on defaulted municipal securities, as described herein, will be excludable from gross income in the same manner as interest payments from the insured municipal securities, and consequently such insurance proceeds may be included in exempt-interest dividends which are designated and paid by the Fund.

Substantially all of the dividends paid by the Fund are anticipated to be exempt from federal income taxes. Shortly after the close of each calendar year, a notice is sent to each shareholder advising him of the total dividends paid into his account for the year and the portion of such total that is exempt from federal income taxes. This portion is determined by the ratio of the tax-exempt income to total income for the entire year and, thus, is an annual average rather than a day-by-day determination for each shareholder.

Distributions out of taxable interest income, other investment income, and short-term capital gains are taxable to shareholders as ordinary income. Since the Fund’s investment income is derived from interest rather than dividends, no portion of such distributions is eligible for the dividends-received deduction available to corporations. Furthermore, since the Fund’s investment income is derived from interest rather than dividends, it is expected that for non-

corporate shareholders no portion of such distributions will be treated as “qualified dividend income” taxable at the reduced tax rates applicable to long-term capital gains. Long-term capital gains, if any, distributed by the Fund to a shareholder are taxable to the shareholder as long-term capital gain, irrespective such shareholder’s holding period in his or her shares.

If the Fund’s distributions exceed its income and capital gains realized in any year and the Fund has current and accumulated earnings and profits for federal income tax purposes, then all or a portion of those distributions may be treated as ordinary income to shareholders for federal income tax purposes.

If a shareholder holds shares for six months or less and during that time receives a distribution of long-term capital gains, any loss realized on the sale of the shares during such six-month period would be a long-term capital loss to the extent of such distribution. If a shareholder holds shares for six months or less and during that time receives a distribution of tax-exempt interest income, any loss realized on the sale of the shares would be disallowed to the extent of the distribution.

Options and Futures Contracts. Certain listed options and regulated futures contracts are considered “section 1256 contracts” for federal income tax purposes. Section 1256 contracts held by the Fund at the end of each taxable year will be “marked to market” and treated for federal income tax purposes as though sold for fair market value on the last business day of such taxable year. Gain or loss realized by the Fund on section 1256 contracts will generally be considered 60% long-term and 40% short-term capital gain or loss. The Fund can elect to exempt its section 1256 contracts which are part of a “mixed straddle” (as described below) from the application of section 1256.

With respect to over-the-counter options, gain or loss realized by the Fund upon the lapse or sale of such options held by the Fund will be either long-term or short-term capital gain or loss depending upon the Fund’s holding period with respect to such option. However, gain or loss realized upon the lapse or closing out of such options that are written by the Fund will be treated as short-term capital gain or loss. In general, if the Fund exercises an option, or an option that the Fund has written is exercised, gain or loss on the option will not be separately recognized but the premium received or paid will be included in the calculation of gain or loss upon disposition of the property underlying the option.

Original Issue Discount and Market Discount Obligations. Under the current original issue discount rules, the Fund will include in its net investment income as interest each year, in addition to stated interest received on obligations held by the Fund, tax-exempt interest income attributable to the Fund from holding zero-coupon municipal securities. These rules require that a holder (such as the Fund) of a discount obligation accrue as income each year a portion of the original issue discount (i.e., the amount equal to the excess of the stated redemption price of the security at maturity over its issue price) attributable to such obligation even though the Fund does not receive interest payments in cash on the security during the year which reflect the accrued discount. As a result of the above rules, in order to make the distributions necessary for the Fund not to be subject to federal income or excise taxes, the Fund may be required to pay out as an income distribution each year an amount greater than the total amount of cash which the Fund has actually received as interest during the year. Such distributions will be made from the cash assets of the Fund, from borrowings or by liquidation of portfolio securities, if necessary. If

a distribution of cash necessitates the liquidation of portfolio securities, the Adviser will select which securities to sell. The Fund may realize a gain or loss from such sales. In the event the Fund realizes capital gains from such sales, its shareholders may receive larger distributions than they would receive in the absence of such sales. Under the market discount rules, a Fund may recognize ordinary income from the sale of bonds which it purchased at a discount to their issue price in the secondary market.

U.S. Federal Income Taxation of the All Market Real Return Portfolio

The following discussion relates to certain significant U.S. federal income tax consequences to the All Market Real Return Portfolio with respect to the determination of its “investment company taxable income” each year. This discussion assumes that the Fund will be taxed as a regulated investment company for each of its taxable years.

Investments in the Wholly-Owned Subsidiary. As described in the Prospectus, the Fund may gain exposure to the commodities markets through investments in commodity-linked derivative instruments. On December 16, 2005, the IRS issued Revenue Ruling 2006-1 which held that income derived from commodity index-linked swaps would not be qualifying income. As such, the Fund’s ability to utilize commodity index-linked swaps as part of its investment strategy is limited to a maximum of 10 percent of its gross income.

A subsequent revenue ruling, Revenue Ruling 2006-31, clarified the holding of Revenue Ruling 2006-1 by providing that income from alternative investment instruments (such as certain commodity index-linked notes) that create commodity exposure may be considered qualifying income under the Code. The IRS has also issued several private letter rulings in which the IRS specifically concluded that income from certain commodity index-linked swaps is qualifying income, in certain circumstances. Based on the reasoning in such rulings, the Fund will seek to gain exposure to the commodity markets primarily through investments in commodity-linked derivative instruments and through investments in its Subsidiary (as discussed below).

As discussed in “Information about the Funds and Their Investments – Investments in the Wholly-Owned Subsidiary”, the Fund intends to invest a portion of its assets in the Subsidiary, which will be classified as a corporation for U.S. federal income tax purposes. The Fund has received a private letter ruling from the IRS confirming that income derived from the Fund’s investment in the Subsidiary will constitute qualifying income to the Fund. In September 2016, the IRS issued Proposed Treasury Regulations which would treat income derived by the Fund from the Subsidiary as qualifying income only to the extent that such income is currently distributed to the Fund. However, in 2019, the IRS issued final Treasury Regulations which treat income derived by the Fund from the Subsidiary as qualifying income regardless of whether such amounts are distributed.

The Subsidiary will be treated as a controlled foreign corporation (“CFC”). The Fund will be treated as a “United States shareholder” of the Subsidiary. As a result, the Fund will be required to include in gross income for U.S. federal income tax purposes all of the Subsidiary’s “subpart F income”, whether or not such income is distributed by the Subsidiary. It is expected that all of the Subsidiary’s income will be “subpart F income”. The Fund’s recognition of the Subsidiary’s “subpart F income” will increase the Fund’s tax basis in the Subsidiary. Distributions by the Subsidiary to the Fund will be tax-free, to the extent of its previously

undistributed “subpart F income”, and will correspondingly reduce the Fund’s tax basis in the Subsidiary. “Subpart F income” is generally treated as ordinary income, regardless of the character of the Subsidiary’s underlying income. If a net loss is realized by the Subsidiary, such loss is not generally available to offset the income earned by the Fund.

Foreign corporations, such as the Subsidiary, will generally not be subject to U.S. federal income taxation unless they are deemed to be engaged in a U.S. trade or business. It is expected that the Subsidiary will conduct its activities in a manner so as to meet the requirements of a safe harbor under Section 864(b)(2) of the Code under which the Subsidiary may engage in trading in stocks or securities or certain commodities without being deemed to be engaged in a U.S. trade or business. However, if certain of the Subsidiary’s activities were determined not to be of the type described in the safe harbor (which is not expected), then the activities of the Subsidiary may constitute a U.S. trade or business, or be taxed as such.

In general, foreign corporations, such as the Subsidiary, that do not conduct a U.S. trade or business are nonetheless subject to tax at a flat rate of 30 percent (or lower tax treaty rate), generally payable through withholding, on the gross amount of certain U.S.-source income that is not effectively connected with a U.S. trade or business. There is presently no tax treaty in force between the U.S. and the Cayman Islands that would reduce this rate of withholding tax. It is not expected that the Subsidiary will derive income subject to such withholding tax.

Based, in part, on Revenue Ruling 2006-31, IRS guidance and advice of counsel, the Fund will seek to gain exposure to the commodity markets primarily through investments in commodity-linked derivatives and through investments in the Subsidiary. The use of commodity-linked derivative instruments involves specific risks. The Prospectus, under the heading “Additional Information about the Fund’s Strategies, Risks and Investments – Derivatives” provides further information regarding commodity-linked derivative instruments, including the risks associated with these instruments.

Stripped-Mortgage Related Securities. Certain classes of SMRS which are issued at a discount, the payments of which are subject to acceleration by reason of prepayments of the underlying Mortgage Assets securing such classes, are subject to special rules for determining the portion of the discount at which the class was issued which must be accrued as income each year. Under Code section 1272(a)(6), a principal-only class or a class which receives a portion of the interest and a portion of the principal from the underlying Mortgage Assets is subject to rules which require accrual of interest to be calculated and included in the income of a holder (such as the Fund) based on the increase in the present value of the payments remaining on the class, taking into account payments includable in the class’s stated redemption price at maturity which are received during the accrual period. For this purpose, the present value calculation is made at the beginning of each accrual period (i) using the yield to maturity determined for the class at the time of its issuance (determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of the accrual period), calculated on the assumption that certain prepayments will occur, and (ii) taking into account any prepayments that have occurred before the close of the accrual period. Since interest included in the Fund’s income as a result of these rules will have been accrued and not actually paid, the Fund may be required to pay out as an income distribution each year an amount which is greater than the total amount of cash interest it actually received, with possible results as described above.

Other Taxes

A Fund may be subject to other state and local taxes.

Taxation of Foreign Stockholders

Taxation of a shareholder who, under the Code, is a nonresident alien individual, foreign trust or estate, foreign corporation or foreign partnership (“foreign shareholder”), depends on whether the income from the Fund is “effectively connected” with a U.S. trade or business carried on by the foreign shareholder.

If the income from a Fund is not effectively connected with the foreign shareholder’s U.S. trade or business, then, except as discussed below, distributions of the Fund attributable to ordinary income paid to a foreign shareholder by the Fund will be subject to U.S. withholding tax at the rate of 30% (or lower treaty rate) upon the gross amount of the distribution. Distributions of the Fund attributable to U.S. source portfolio interest income are not subject to this withholding tax.

A foreign shareholder generally would be exempt from Federal income tax on distributions of a Fund attributable to net long-term and short-term capital gain and on gain realized from the sale or redemption of shares of the Fund. Special rules apply in the case of a shareholder that is a foreign trust or foreign partnership.

If the income from a Fund is effectively connected with a foreign shareholder’s U.S. trade or business, then ordinary income distributions, capital gain distributions and any gain realized upon the sale of shares of the Fund will be subject to Federal income tax at the rates applicable to U.S. citizens or U.S. corporations.

The tax consequences to a foreign shareholder entitled to claim the benefits of an applicable tax treaty may be different from those described herein.

The tax rules of other countries with respect to an investment in a Fund can differ from the Federal income taxation rules described above. These foreign rules are not discussed herein. Foreign shareholders are urged to consult their own tax advisors as to the consequences of foreign tax rules with respect to an investment in the Fund.

Subject to the general oversight of the Board, the Adviser is responsible for the investment decisions and the placing of orders for portfolio transactions for the Funds. The Adviser determines the broker or dealer to be used in each specific transaction with the objective of negotiating a combination of the most favorable commission (for transactions on which a commission is payable) and the best price obtainable on each transaction (generally defined as “best execution”). In connection with seeking best execution, a Fund does not consider sales of shares of the Fund or other investment companies managed by the Adviser as a factor in the selection of brokers and dealers to effect portfolio transactions and has adopted policies and procedures reasonably designed to preclude such considerations.

Most of the transactions for the Funds, including transactions in listed securities, are executed in the over-the-counter market by market maker dealers with whom the Adviser maintains regular contact. Most transactions made by the Funds will be principal transactions at net prices and the Funds will incur little or no brokerage costs. However, a Fund may make opportunistic investments in equities from time to time and All Market Real Return Portfolio regularly invests in equity securities. The Funds will incur brokerage commissions on those transactions. Where possible, securities will be purchased directly from the issuer or from an underwriter or market maker for the securities unless the Adviser believes a better execution is available elsewhere. Purchases from underwriters of newly-issued securities for inclusion in the Funds’ portfolios usually will include a concession paid to the underwriter by the issuer, and purchases from dealers serving as market makers will include the spread between the bid and ask price.

When consistent with the objective of obtaining best execution, brokerage may be directed to persons or firms supplying investment information to the Adviser. There may be occasions where the transaction cost charged by a broker may be greater than that which another broker may charge if it is determined in good faith that the amount of such transaction cost is reasonable in relation to the value of the brokerage, research and statistical services provided by the executing broker.

No Fund has an obligation to enter into transactions in portfolio securities with any broker, dealer, issuer, underwriter or other entity. In placing orders, it is the policy of a Fund to obtain the best execution for its transactions. Where best execution may be obtained from more than one broker or dealer, the Adviser may, in its discretion, purchase and sell securities through brokers and dealers who provide research, statistical and other information to the Adviser. Such services may be used by the Adviser for all of its investment advisory accounts and, accordingly, not all such services may be used by the Adviser in connection with the Funds. The supplemental information received from a dealer is in addition to the services required to be performed by the Adviser under the Advisory Agreements, and the expenses of the Adviser will not necessarily be reduced as a result of the receipt of such information.

Neither the Funds nor the Adviser have entered into agreements or understandings with any brokers regarding the placement of securities transactions because of research services they provide. A broker-dealer may provide the Adviser with research or related services with an

expectation, but not necessarily an explicit agreement or contract, that the Adviser will use the broker-dealer to execute client transactions in the future. To the extent that such persons or firms supply investment information to the Adviser for use in rendering investment advice to a Fund, such information may be supplied at no cost to the Adviser and, therefore, may have the effect of reducing the expenses of the Adviser in rendering advice to the Fund. While it is impracticable to place an actual dollar value on such investment information, the Adviser believes that its receipt probably does not reduce the overall expenses of the Adviser to any material extent.

The investment information provided to the Adviser is of the type described in Section 28(e) of the Securities Exchange Act of 1934, as amended, and is designed to augment the Adviser’s own internal research and investment strategy capabilities. Research services furnished by brokers through which a Fund effects securities transactions are used by the Adviser in carrying out its investment management responsibilities with respect to all its clients’ accounts but not all such services may be used by the Adviser in connection with a Fund.

Investment decisions for a Fund are made independently from those for other investment companies and other advisory accounts managed by the Adviser. It may happen, on occasion, that the same security is held in the portfolio of a Fund and one or more of such other companies or accounts. Simultaneous transactions are likely when several funds or accounts are managed in accordance with a similar strategy by the Adviser, particularly when a security is suitable for the investment objectives of more than one of such companies or accounts. When two or more companies or accounts managed by the Adviser are simultaneously engaged in the purchase or sale of the same security, the transactions are allocated to the respective companies or accounts both as to amount and price, in accordance with a method deemed equitable to each company or account. In some cases this system may adversely affect the price paid or received by the Fund or the size of the position obtainable for the Fund.

The Adviser continuously monitors and evaluates the performance and execution capabilities of brokers that transact orders for the Funds to ensure consistent quality executions. This information is reported to the Adviser’s Research Allocation Committee and Best Execution Committee, which oversee broker-selection issues. In addition, the Adviser periodically reviews the Funds’ transaction costs in light of current market circumstances using internal tools and analysis as well as statistical analysis and other relevant information from external vendors.

Allocations are made by the Adviser. Purchases and sales of portfolio securities are determined by the Adviser and are placed with broker-dealers by the trading department of the Adviser.

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, Bond Inflation Strategy incurred brokerage commissions amounting in the aggregate to $32,766, $32,698 and $27,652, respectively.

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, Municipal Bond Inflation Strategy incurred no brokerage commissions.

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021, All Market Real Return Portfolio incurred brokerage commissions amounting in the aggregate to $370,852, $548,951 and $488,684, respectively.

All Market Real Return Portfolio may, from time to time, place orders for the purchase or sale of securities (including listed call options) with SCB & Co. and Bernstein Autonomous LLP (a United Kingdom broker-dealer), affiliates of the Adviser (the “Affiliated Brokers”). In such instances, the placement of orders with the Affiliated Brokers would be consistent with All Market Real Return Portfolio’s objective of obtaining best execution and would not be dependent upon the fact that the Affiliated Brokers are affiliates of the Adviser. With respect to orders placed with the Affiliated Brokers for execution on a national securities exchange, commissions received must conform to Section 17(e)(2)(A) of the 1940 Act and Rule 17e-1 thereunder, which permit an affiliated person of a registered investment company (such as All Market Real Return Portfolio), or any affiliated person of such person, to receive a brokerage commission, from such registered investment company provided that such commission is reasonable and fair compared to the commissions received by other brokers in connection with comparable transactions involving similar securities during a comparable period of time.

During the fiscal years ended October 31, 2023, October 31, 2022 and October 31, 2021 All Market Real Return Portfolio paid brokerage commissions to the Affiliated Brokers amounting in the aggregate to $0, $0 and $0, respectively.  During the fiscal year ended October 31, 2023, the percentage of aggregate brokerage commissions paid to the Affiliated Brokers and the percentage aggregate dollar amount of transactions involving payment of commissions effected through the Affiliated Brokers by All Market Real Return Portfolio was 0% and 0%, respectively.

As of the end of the most recent fiscal year, each Fund listed below owned securities of its regular brokers or dealers (as defined in Rule 10b-1 under the 1940 Act) or their parents as follows:

Disclosure of Portfolio Holdings

Each Fund believes that the ideas of the Adviser’s investment staff should benefit the Fund and its shareholders, and does not want to afford speculators an opportunity to profit by

anticipating Fund trading strategies or using Fund information for stock picking. However, each Fund also believes that knowledge of the Fund’s portfolio holdings can assist shareholders in monitoring their investment, making asset allocation decisions, and evaluating portfolio management techniques.

The Adviser has adopted, on behalf of each Fund, policies and procedures relating to disclosure of the Fund’s portfolio securities. The policies and procedures relating to disclosure of the Fund’s portfolio securities are designed to allow disclosure of portfolio holdings information where necessary to the Fund’s operation or useful to the Fund’s shareholders without compromising the integrity or performance of the Fund. Except when there are legitimate business purposes for selective disclosure and other conditions (designed to protect the Fund and its shareholders) are met, the Fund does not provide or permit others to provide information about the Fund’s portfolio holdings on a selective basis.

Each Fund includes portfolio holdings information as required in regulatory filings and shareholder reports, discloses portfolio holdings information as required by federal or state securities laws and may disclose portfolio holdings information in response to requests by governmental authorities. In addition, the Adviser may post portfolio holdings information on the Adviser’s website (www.abfunds.com). The Adviser generally posts on the website a complete schedule of the Fund’s portfolio securities, generally as of the last day of each calendar month, approximately 30 days after the end of that month. This posted information generally remains accessible on the website for three months. For each portfolio security, the posted information includes its name, the number of shares held by the Fund, the market value of the Fund’s holdings, and the percentage of the Fund’s assets represented by the Fund’s holdings. In addition to the schedule of portfolio holdings, the Adviser may post information about the number of securities the Fund holds, a summary of the Fund’s top ten holdings (including name and the percentage of the Fund’s assets invested in each holding), and a percentage breakdown of the Fund’s investments by country, sector, industry, credit risk or securities type, as applicable, approximately 45 days after the end of the month. The day after portfolio holdings information is publicly available on the website, it may be mailed, e-mailed or otherwise transmitted to any person.

The Adviser may distribute or authorize the distribution of information about a Fund’s portfolio holdings that is not publicly available, on the website or otherwise, to the Adviser’s employees and affiliates that provide services to the Fund. In addition, the Adviser may distribute or authorize distribution of information about a Fund’s portfolio holdings that is not publicly available, on the website or otherwise, (i) to the Fund’s service providers who require access to the information in order to fulfill their contractual duties relating to the Fund (including, without limitation, pricing services and proxy voting services), (ii) to facilitate the review of the Fund by NRSROs, (iii) for the purpose of due diligence regarding a merger or acquisition, (iv) for the purpose of effecting in-kind redemption of securities to facilitate orderly redemption of portfolio assets and minimal impact on remaining Fund shareholders, or (v) to other persons approved by the Adviser’s Chief Compliance Officer (or his designee) in accordance with the conditions described below that are part of the policies and procedures relating to disclosure of the Fund’s portfolio securities. The Adviser does not expect to disclose information about a Fund’s portfolio holdings that is not publicly available to the Fund’s individual or institutional investors or to intermediaries that distribute the Fund’s shares. Information may be disclosed with any frequency and any lag, as appropriate.

Before any non-public disclosure of information about a Fund’s portfolio holdings is permitted, however, the Adviser’s Chief Compliance Officer (or his designee) must determine that the Fund has a legitimate business purpose for providing the portfolio holdings information, that the disclosure is in the best interests of the Fund’s shareholders, and that the recipient agrees or has a duty to keep the information confidential and agrees not to trade directly or indirectly based on the information or to use the information to form a specific recommendation about whether to invest in the Fund or any other security. Under no circumstances may the Adviser or its affiliates receive any consideration or compensation for disclosing the information.

The Adviser has established procedures to ensure that each Fund’s portfolio holdings information is only disclosed in accordance with these policies. Only the Adviser’s Chief Compliance Officer (or his designee) may approve the disclosure, and then only if he or she and a designated senior officer in the Adviser’s product management group determines that the disclosure serves a legitimate business purpose of the Fund and is in the best interest of the Fund’s shareholders. The Adviser’s Chief Compliance Officer (or his designee) approves disclosure only after considering the anticipated benefits and costs to the Fund and its shareholders, the purpose of the disclosure, any conflicts of interest between the interests of the Fund and its shareholders and the interests of the Adviser or any of its affiliates, and whether the disclosure is consistent with the policies and procedures governing disclosure. Only someone approved by the Adviser’s Chief Compliance Officer (or his designee) may make approved disclosures of portfolio holdings information to authorized recipients. The Adviser reserves the right to request certifications from senior officers of authorized recipients that the recipient is using the portfolio holdings information only in a manner consistent with the Adviser’s policy and any applicable confidentiality agreement. The Adviser’s Chief Compliance Officer (or his designee) or another member of the compliance team reports all arrangements to disclose portfolio holdings information to the Fund’s Board on a quarterly basis. If the Board determines that disclosure was inappropriate, the Adviser will promptly terminate the disclosure arrangement.

In accordance with these procedures, each of the following third parties has been approved to receive information concerning each Fund’s portfolio holdings: (i) the Fund’s independent registered public accounting firm, for use in providing audit opinions; (ii) Donnelley Financial Solutions, Inc., Data Communique International and, from time to time, other financial printers, for the purpose of preparing Fund regulatory filings; (iii) the Fund’s custodian in connection with its custody of the Fund’s assets; (iv) Institutional Shareholder Services, Inc. for proxy voting services; (v) the Investment Company Institute, a trade association that represents registered investment companies such as mutual funds, closed-end funds and exchange-traded funds, in connection with confidential industry matters; and (vi) data aggregators, such as Vestek. Information may be provided to these parties at any time with no time lag. Each of these parties is contractually and ethically prohibited from sharing the Fund’s portfolio holdings information unless specifically authorized.

Description of the Funds

Each Fund is a series of AB Bond Fund, Inc., a Maryland corporation. The Funds were organized in 2009 under the name of “AllianceBernstein Bond Inflation Strategy”, “AllianceBernstein Municipal Bond Inflation Strategy” and “AllianceBernstein Multi-Asset Inflation Strategy”, respectively. AllianceBernstein Multi-Asset Inflation Strategy’s name became “AllianceBernstein Real Asset Strategy” on September 27, 2010. AllianceBernstein Real Asset Strategy’s name became “AllianceBernstein All Market Real Return Portfolio” on December 12, 2014. On January 20, 2015, the Company changed its name from “AllianceBernstein Bond Fund, Inc.” to “AB Bond Fund, Inc.,” and the Funds changed their names from AllianceBernstein Bond Inflation Strategy, AllianceBernstein Municipal Bond Inflation Strategy, and AllianceBernstein All Market Real Return Portfolio to “AB Bond Inflation Strategy,” “AB Municipal Bond Inflation Strategy”, and “AB All Market Real Return Portfolio”, respectively.

A shareholder will be entitled to share pro-rata with other holders of the same class of shares all dividends and distributions arising from the Fund’s assets and, upon redeeming shares, will receive the then-current NAV of the Fund represented by the redeemed shares less any applicable CDSC. The Company is empowered to establish, without shareholder approval, additional portfolios, which may have different investment objectives and policies than those of the Fund, and additional classes of shares within a Fund. If an additional portfolio or class were established in the Fund, each share of the portfolio or class would normally be entitled to one vote for all purposes. Generally, shares of each portfolio and class would vote together as a single class on matters, such as the election of Directors, that affect each portfolio and class in substantially the same manner.

Each class of shares of the Fund represents an interest in the same portfolio of investments and has the same rights and is identical in all respects, except that each of Class A, Class C, Class R, Class 1 and Class K shares of the Fund bears its own distribution expenses; and Class C shares convert to Class A shares under certain circumstances. Each class of shares of the Fund votes separately with respect to the Company’s Rule 12b-1 distribution plan and other matters for which separate class voting is appropriate under applicable law. Shares are, when issued, fully paid and non-assessable, freely transferable, entitled to dividends as determined by the Directors and, in liquidation of a Fund, entitled to receive the net assets of a Fund.

It is anticipated that annual shareholder meetings will not be held; shareholder meetings will be held only when required by federal or state law. Shareholders have available certain procedures for the removal of Directors.
