INVESTMENT PRACTICES AND RISK FACTORS

In addition to the investment strategies and the risks described in the Fund’s Prospectus and in this SAI under Investment Objective and Strategies, the Fund may employ other investment practices and may be subject to other risks, which are described below. The Fund may engage in the practices described below to the extent consistent with its investment objectives, strategies, policies and restrictions. However, as with any investment or investment technique, even when the Fund’s Prospectus or this discussion indicates that the Fund may engage in an activity, the Fund may not actually do so for a variety of reasons. In addition, new types of instruments and other securities may be developed and marketed from time to time.

Table of Contents

Consistent with its investment limitations, the Fund expects to invest in those new types of securities and instruments that its portfolio manager believes may assist the Fund in achieving its investment objective.

This discussion is not intended to limit the Fund’s investment flexibility, unless such a limitation is expressly stated, and therefore will be construed by the Fund as broadly as possible. Statements concerning what the Fund may do are not intended to limit any other activity.

Bank Obligations

The Fund may invest in all types of bank obligations, including certificates of deposit (“CDs”), time deposits and bankers’ acceptances. CDs are short-term negotiable obligations of commercial banks. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers usually in connection with international transactions.

U.S. commercial banks organized under federal law are supervised and examined by the Comptroller of the Currency and are required to be members of the Federal Reserve System and to be insured by the Federal Deposit Insurance Corporation (the “FDIC”). U.S. banks organized under state law are supervised and examined by state banking authorities, but are members of the Federal Reserve System only if they elect to join. Most state banks are insured by the FDIC (although such insurance may not be of material benefit to the Fund, depending upon the principal amount of CDs of each bank held by the Fund) and are subject to federal examination and to a substantial body of federal law and regulation. As a result of federal and state laws and regulations, U.S. branches of U.S. banks are, among other things, generally required to maintain specified levels of reserves, and are subject to other supervision and regulation designed to promote financial soundness. Banks may be particularly susceptible to certain economic factors, such as interest rate changes and adverse developments in the market for real estate. Fiscal and monetary policy and general economic cycles can affect the availability and cost of funds, loan demand and asset quality and thereby impact the earnings and financial conditions of banks.

Obligations of foreign branches of U.S. banks, such as CDs and time deposits, may be general obligations of the parent bank in addition to the issuing branch, or may be limited by the terms of a specific obligation and governmental regulation. Such obligations are subject to different risks than are those of U.S. banks or U.S. branches of foreign banks. These risks relate to foreign economic and political developments, foreign governmental restrictions that may adversely affect payment of principal and interest on the obligations, foreign exchange controls and foreign withholding and other taxes on interest income. Foreign branches of U.S. banks and foreign branches of foreign banks are not necessarily subject to the same or similar regulatory requirements that apply to U.S. banks, such as mandatory reserve requirements, loan limitations and accounting, auditing and financial recordkeeping requirements. In addition, less information may be publicly available about a foreign branch of a U.S. bank or about a foreign bank than about a U.S. bank.

Obligations of U.S. branches of foreign banks may be general obligations of the parent bank, in addition to the issuing branch, or may be limited by the terms of a specific obligation and by federal and state regulation as well as governmental action in the country in which the foreign bank has its head office. A U.S. branch of a foreign bank with assets in excess of $1 billion may or may not be subject to reserve requirements imposed by the Federal Reserve System or by the state in which the branch is located if the branch is licensed in that state. In addition, branches licensed by the Comptroller of the Currency and branches licensed by certain states (“State Branches”) may or may not be required to: (a) pledge to the regulator, by depositing assets with a designated bank within the state; and (b) maintain assets within the state in an amount equal to a specified percentage of the aggregate amount of liabilities of the foreign bank payable at or through all of its agencies or branches within the state. The deposits of State Branches may not necessarily be insured by the FDIC. In addition, there may be less publicly available information about a U.S. branch of a foreign bank than about a U.S. bank.

Commercial Paper

Commercial paper (including variable amount master demand notes and funding agreements) consists of short-term, unsecured promissory notes issued by corporations, partnerships, trusts and other entities to finance short-term credit needs.

Common Stock

Common stocks are shares of a corporation or other entity that entitle the holder to a pro rata share of the profits of the corporation, if any, without preference over any other shareholder or class of shareholders, including holders of the entity’s

7

Table of Contents

preferred stock and other senior equity securities. Common stock usually carries with it the right to vote and frequently an exclusive right to do so.

Convertible Securities

Convertible securities are fixed income securities (usually debt or preferred stock) that may be converted or exchanged for a prescribed amount of common stock or other equity securities of the same or a different issuer within a particular period of time at a specified price or formula. A convertible security entitles the holder to receive interest paid or accrued on debt or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. Before conversion or exchange, convertible securities ordinarily provide a stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower than the yield of nonconvertible debt. However, there can be no assurance of current income because the issuers of the convertible securities may default on their obligations. Convertible securities are usually subordinated to comparable nonconvertible debt or preferred stock, but rank senior to common stock in a corporation’s capital structure.

The value of a convertible security is generally related to (1) its yield in comparison with the yields of other securities of comparable maturity and quality that do not have a conversion privilege and/or (2) its worth, at market value, if converted or exchanged into the underlying common stock. A convertible security may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument, which may be less than the ultimate conversion or exchange value.

Convertible securities are subject both to the stock market risk associated with equity securities and to the credit and interest rate risks associated with fixed income securities. As the market price of the equity security underlying a convertible security falls, the convertible security tends to trade on the basis of its yield and other fixed income characteristics. As the market price of such equity security rises, the convertible security tends to trade on the basis of its equity conversion features. Investments in convertible securities generally entail less risk than investments in common stock of the same issuer.

Synthetic Convertible Securities

A synthetic convertible security is comprised of two distinct securities that together resemble convertible securities in certain respects. Synthetic convertible securities are created by combining non-convertible bonds or preferred shares with common stocks, warrants or stock call options. The options that will form elements of synthetic convertible securities will be listed on a securities exchange. The two components of a synthetic convertible security, which will be issued with respect to the same entity, generally are not offered as a unit, and may be purchased and sold by the Fund at different times. Synthetic convertible securities differ from convertible securities in certain respects, including that each component of a synthetic convertible security has a separate market value and responds differently to market fluctuations. Investing in synthetic convertible securities involves the risk normally involved in holding the securities comprising the synthetic convertible security.

Cybersecurity Risk

With the increased use of technologies such as mobile devices and Web-based or “cloud” applications, and the dependence on the Internet and computer systems to conduct business, the Fund is susceptible to operational, information security and related risks. In general, cybersecurity incidents can result from deliberate attacks or unintentional events (arising from external or internal sources) that may cause the Fund to lose proprietary information, suffer data corruption, physical damage to a computer or network system or lose operational capacity. Cybersecurity attacks include, but are not limited to, infection by malicious software, such as malware or computer viruses or gaining unauthorized access to digital systems, networks or devices that are used to service the Fund’s operations (e.g., through “hacking,” “phishing” or malicious software coding) or other means for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cybersecurity attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on the Fund’s websites (i.e., efforts to make network services unavailable to intended users). In addition, authorized persons could inadvertently or intentionally release confidential or proprietary information stored on the Fund’s systems.

Cybersecurity incidents affecting the Fund’s Manager, the Subadviser, other service providers to the Fund or its shareholders (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) have the ability to cause disruptions and impact business operations, potentially resulting in financial losses to

Table of Contents

both the Fund and its shareholders, interference with the Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareholders to transact business and the Fund to process transactions (including fulfillment of Fund share purchases and redemptions), violations of applicable privacy and other laws (including the release of private shareholder information) and attendant breach notification and credit monitoring costs, regulatory fines, penalties, litigation costs, reputational damage, reimbursement or other compensation costs, forensic investigation and remediation costs, and/or additional compliance costs. Similar adverse consequences could result from cybersecurity incidents affecting issuers of securities in which the Fund invests, counterparties with which the Fund engages in transactions, governmental and other regulatory authorities, exchange and other financial market operators, banks, brokers, dealers, insurance companies and other financial institutions (including financial intermediaries and other service providers) and other parties. In addition, substantial costs may be incurred in order to safeguard against and reduce the risk of any cybersecurity incidents in the future. In addition to administrative, technological and procedural safeguards, the Fund’s Manager and the Subadviser have established business continuity plans in the event of, and risk management systems to prevent or reduce the impact of, such cybersecurity incidents. However, there are inherent limitations in such plans and systems, including the possibility that certain risks have not been identified, as well as the rapid development of new threats. Furthermore, the Fund cannot control the cybersecurity plans and systems put in place by its service providers or any other third parties whose operations may affect the Fund and its shareholders. The Fund and its shareholders could be negatively impacted as a result.

Debt and Fixed Income Securities

The Fund may invest in a variety of debt and fixed income securities, which may be issued by governmental, corporate or other issuers. Debt securities may pay fixed, floating or variable rates of interest or interest at a rate contingent upon some other factor. Variable rate securities reset at specified intervals, while floating rate securities reset whenever there is a change in a specified index rate. In most cases, these reset provisions reduce the effect of market interest rates on the value of the security. However, some securities do not track the underlying index directly, but reset based on formulas that can produce an effect similar to leveraging; others may provide for interest payments that vary inversely with market rates. The market prices of these securities may fluctuate significantly when interest rates change.

These securities share principal risks. For example, the level of interest income generated by the Fund’s fixed income investments may decline due to a decrease in market interest rates. Thus, when fixed income securities mature or are sold, they may be replaced by lower-yielding investments. Also, their values fluctuate with changes in interest rates. A decrease in interest rates will generally result in an increase in the value of the Fund’s fixed income investments. Conversely, during periods of rising interest rates, the value of the Fund’s fixed income investments will generally decline. However, a change in interest rates will not have the same impact on all fixed rate securities. For example, the magnitude of these fluctuations will generally be greater when the Fund’s duration or average maturity is longer. In addition, certain fixed income securities are subject to credit risk, which is the risk that an issuer of securities will be unable to pay principal and interest when due, or that the value of the security will suffer because investors believe the issuer is unable to pay.

Demand Instruments

Demand instruments are securities issued as floating- or variable-rate securities subject to demand features. Demand instruments usually have a stated maturity of more than one year but contain a demand feature (or “put”) that enables the holder to tender the investment at an exercise price equal to approximately the amortized cost of the instrument plus accrued interest on no more than 30 days’ notice. Variable-rate demand instruments provide for automatic establishment of a new interest rate on set dates. Floating-rate demand instruments provide for automatic adjustment of interest rates whenever a specified interest rate (e.g., the prime rate) changes. The Fund currently is permitted to purchase floating rate and variable rate obligations with demand features in accordance with requirements established by the SEC, which, among other things, permit such instruments to be deemed to have remaining maturities of 13 months or less, notwithstanding that they may otherwise have a stated maturity in excess of 13 months. Securities with ultimate maturities of greater than 13 months may be purchased only pursuant to Rule 2a-7 of the 1940 Act. Frequently, floating rate and variable rate obligations are secured by letters of credit or other credit support arrangements provided by banks.

Securities with demand features may involve certain expenses and risks, including the inability of the issuer of the instrument to pay for the securities at the time the instrument is exercised, non-marketability of the instrument and differences between the maturity of the underlying security and the maturity of the instrument. Securities may cost more with demand features than without them. Demand features can serve three purposes: (i) to shorten the maturity of a variable or floating rate

9

Table of Contents

security, (ii) to enhance the instrument’s credit quality and (iii) to provide a source of liquidity. Demand features are often issued by third party financial institutions, generally domestic and foreign banks, and by brokerage firms or insurance companies. Accordingly, the credit quality and liquidity of the Fund’s investments may be dependent in part on the credit quality of the institutions supporting the Fund’s investments and changes in the credit quality of these institutions could cause losses to the Fund and affect its share price.

Variable rate demand instruments include variable rate demand preferred shares or other forms of liquidity protected preferred shares that are issued by closed end investment companies that invest in municipal securities. These preferred shares have a liquidation preference and pay a dividend that is set weekly or at some other interval (typically 28 days) by a remarketing agent or through a similar process that is designed to approximate current prevailing interest rates. The Fund, as a holder of one of these instruments, will have the right to tender the securities for remarketing or, if the securities cannot be remarketed, to tender the securities to a liquidity provider, in each case at a price equal to its liquidation preference plus accrued dividends. The Fund would have no right to tender the shares to the issuer for payment or redemption, and the shares will be not freely transferable. The Fund will be subject to the risk that the liquidity provider will not be able to honor its unconditional commitment to purchase the shares.

Derivatives — Generally

A derivative is a financial instrument that has a value based on, or derived from, the value of one or more underlying reference instruments or measures of value or interest rates (“underlying instruments”), such as a security, a commodity, a currency, an index, an interest rate or a currency exchange rate. A derivative can also have a value based on the likelihood that an event will or will not occur. Derivatives include futures contracts, forward contracts, options and swaps.

The Fund may use derivatives for any purpose, including but not limited to, to attempt to enhance income, yield or return, as a substitute for investing directly in a security or asset, or as a hedging technique in an attempt to manage risk in the Fund’s portfolio. The Fund may choose not to make use of derivatives for a variety of reasons, and no assurance can be given that any derivatives strategy employed will be successful. The Fund’s use of derivative instruments may be limited from time to time by applicable law, availability or by policies adopted by the Board or Manager.

The Fund may utilize multiple derivative instruments and combinations of derivative instruments to seek to adjust the risk and return characteristics of its overall position. Combined positions will typically contain elements of risk that are present in each of its component transactions. It is possible that the combined position will not achieve its intended goal and will instead increase losses or risk to the Fund. Because combined positions involve multiple trades, they result in higher transaction costs and may be more difficult to open and close out.

The Fund may enter into derivatives with standardized terms that have no or few special or unusual components, which are generally traded on an exchange, as well as derivatives with more complex features, singly or in combination. Non-standardized derivatives are generally traded over the counter (“OTC”). OTC derivatives may be standardized or have customized features and may have limited or no liquidity. The Fund’s derivatives contracts may be centrally cleared or settled bilaterally directly with a counterparty. The Fund’s derivatives contracts may be cash settled or physically settled.

In addition to the instruments and strategies discussed in this section, additional opportunities in connection with derivatives and other similar or related techniques may become available to the Fund as a result of the development of new techniques, the development of new derivative instruments or a regulatory authority broadening the range of permitted transactions. The Fund may utilize these opportunities and techniques to the extent that they are consistent with the Fund’s investment objectives and permitted by its investment limitations and applicable regulatory authorities. These opportunities and techniques may involve risks different from or in addition to those summarized herein.

Risks Associated with Hedging with Derivatives . If the portfolio manager uses a hedging strategy at the wrong time or judges market conditions incorrectly, hedging strategies may reduce the Fund’s return. Successful use of derivatives to hedge positions depends on the correlation between the price of the derivative and the price of the hedged asset.

The Fund may attempt to protect against declines in the value of the Fund’s portfolio assets by entering into a variety of derivatives transactions, including selling futures contracts, entering into swaps or purchasing puts on indices or futures contracts (short hedging). Short hedging involves the risk that the prices of the futures contracts or the value of the swap or the applicable index will correlate imperfectly with price movements in the Fund’s assets. If the value of the assets held in the Fund’s portfolio declines while the Fund has used derivative instruments in a short hedge, and the prices referenced in the short hedge do not also decline, the value of the Fund’s assets would decline, and the short hedge would not hedge or mitigate the loss in the value of the assets. With respect to a derivative transaction based on an index, the risk of imperfect correlation increases as the composition of the Fund’s portfolio diverges from the assets included in the applicable index. To compensate for the imperfect correlation of movements in the price of the portfolio securities being hedged and movements in the price of the hedging instruments, the Fund may use derivative instruments in a greater dollar amount than the dollar amount of portfolio assets being hedged. It might do so if the historical volatility of the prices of the portfolio assets being hedged is more than the historical volatility of the applicable index.

If the Fund has used derivatives to hedge or otherwise reduce the Fund’s risk exposure to a particular position and then disposes of that position at a time at which it cannot also settle, terminate or close out the corresponding hedge position, this may create short investment exposure. Certain “short” derivative positions involve investment leverage, and the amount of the Fund’s potential loss is theoretically unlimited.

Table of Contents

The Fund can use derivative instruments to establish a position in the market as a temporary substitute for the purchase of individual securities or other assets (long hedging) by buying futures contracts and/or calls on such futures contracts, indices or on securities or other assets, or entering into swaps. It is possible that when the Fund does so the market might decline. If the Fund then decides not to invest in the assets because of concerns that the market might decline further or for other reasons, the Fund will realize a loss on the hedge position that is not offset by a reduction in the price of the asset the Fund had intended to purchase.

Risk of Government Regulation of Derivatives. The regulation of derivatives transactions and funds that engage in such transactions is an evolving area of law and is subject to modification by government and judicial action. It is impossible to fully predict the effects of new and existing legislation and regulation, but the effects could be substantial and adverse. Additional regulation could, among other things, make derivatives more costly, limit their availability or utility, otherwise adversely affect their performance or disrupt markets. Such regulation may limit or prevent the Fund from using derivatives as part of its investment strategy and could ultimately prevent the Fund from being able to achieve its investment goals. Limitations or restrictions applicable to the counterparties with which the Fund engages in derivative transactions could also prevent the Fund from using derivatives or affect pricing or other factors relating to derivatives or may change the availability of certain investments.

The Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) has caused broad changes to the OTC derivatives market and granted significant authority to the SEC and the CFTC to regulate OTC derivatives and market participants. Pursuant to such authority, rules have been enacted that currently require clearing of many OTC derivatives transactions and may require clearing of additional OTC derivatives transactions in the future and that impose minimum margin and capital requirements for uncleared OTC derivatives transactions. Similar regulations are being adopted in other jurisdictions around the world. The implementation of the clearing requirement has increased the costs of derivatives transactions since investors have to pay fees to clearing members and are typically required to post more margin for cleared derivatives than had historically been the case. The costs of derivatives transactions are expected to increase further as clearing members raise their fees to cover the costs of additional capital requirements and other regulatory changes. While the new rules and regulations and central clearing of some derivatives transactions are designed to reduce systemic risk (i.e., the risk that the interdependence of large derivatives dealers could cause them to suffer liquidity, solvency or other challenges simultaneously), there is no assurance that they will achieve that result, and in the meantime, mandatory clearing of derivatives may expose the Fund to new kinds of costs and risks.

Additionally, new regulations may result in increased uncertainty about credit/counterparty risk and may limit the flexibility of the Fund to protect its interests in the event of an insolvency of a derivatives counterparty. In the event of a counterparty’s (or its affiliate’s) insolvency, the Fund’s ability to exercise remedies, such as the termination of transactions, netting of obligations and realization on collateral, could be stayed or eliminated under the rules of the applicable exchange or clearing corporation or under new special resolution regimes adopted in the United States, the European Union and various other jurisdictions. Such regimes provide government authorities with broad authority to intervene when a financial institution is experiencing financial difficulty. In particular, with respect to counterparties who are subject to such proceedings in the European Union, the liabilities of such counterparties to the Fund could be reduced, eliminated, or converted to equity in such counterparties (sometimes referred to as a “bail in”).

Cover. The Fund’s use of derivatives may create financial obligations to third parties which if not covered could be construed as “senior securities” (as defined in the 1940 Act). To the extent that the Fund determined that such obligations may be deemed to create “senior securities,” the Fund intends to segregate or earmark liquid assets or otherwise “cover” such obligations. The Fund may cover such obligations using methods that are currently or in the future permitted under the 1940 Act, the rules and regulations thereunder or orders issued by the SEC thereunder and to the extent deemed appropriate by the Fund, interpretations and guidance of the SEC staff.

The Fund segregates with its custodian or otherwise earmarks cash, cash equivalents or liquid assets in an amount the Fund believes to be adequate to ensure that it has sufficient liquid assets to meet its obligations under its derivatives contracts, or the Fund may engage in other measures to “cover” its obligations with respect to such transactions. The amounts that are segregated or earmarked may be based on the derivative’s notional value or on the daily mark-to-market obligation under the derivatives contract and may be reduced by amounts on deposit with the applicable broker or counterparty to the derivatives transaction. The Fund may segregate or earmark amounts in addition to the amounts described above. For example, if the Fund

13

Table of Contents

writes a physically settled put option, it will typically segregate or earmark liquid assets equal to the exercise price of the option, less margin on deposit, or hold the underlying instrument directly; if the Fund writes a cash settled put option, it will typically segregate or earmark liquid assets equal to the amount the option is in the money (meaning the difference between the exercise price of the option and the current market price of the underlying instrument, when the exercise price of the option is higher than the market price of the underlying instrument), marked to market on a daily basis, less margin on deposit. Alternatively, the Fund may, in certain circumstances, enter into an offsetting position rather than segregating or designating liquid assets (e.g., the Fund may cover a written put option with a purchased put option with the same or higher exercise price or cover a written call option with a purchased call option with the same or lower exercise price).

The segregation of assets does not reduce the risks to the Fund of entering into transactions in derivatives. Additionally, although the portfolio manager attempts to ensure that the Fund has sufficient liquid assets in respect of its obligations under its derivative contracts, it is possible that the Fund’s liquid assets may be insufficient to support such obligations under its derivatives positions. The Fund may modify its asset segregation policies from time to time.

Foreign Currency Instruments and Hedging Strategies

The Fund may use options and futures contracts on foreign currencies and forward currency contracts and currency swap agreements (collectively, “Currency Instruments”), deliverable and non-deliverable, to attempt to hedge against movements in the values of the foreign currencies in which the Fund’s securities are denominated or to attempt to enhance the Fund’s return or yield. The Fund may also use such investments to attempt to establish a short position or to gain exposure to a market that would be more costly or difficult to access with other types of investments, such as bonds or currency. The Fund may also engage in foreign currency transactions on a spot (cash) basis at the rate prevailing in the currency exchange market at the time of the transaction. The Fund may determine not to hedge, and the Fund may be completely unhedged at any point in time. In cases when a particular currency is difficult to hedge or difficult to hedge against the U.S. dollar, the Fund may seek to hedge against price movements in that currency by entering into transactions using Currency Instruments on another currency or a basket of currencies, the value of which the portfolio manager believes will have a high degree of positive correlation to the value of the currency being hedged. The risk that movements in the price of the Currency Instrument will not correlate perfectly with movements in the price of the currency subject to the hedging transaction is magnified when this strategy is used.

Currency Instruments Risks. In addition to the risks found under “Derivatives – Risks of Derivatives Generally,” Currency Instruments are subject to the following risks:

The value of Currency Instruments depends on the value of the underlying foreign currency relative to the U.S. dollar. Because foreign currency transactions occurring in the interbank market might involve substantially larger amounts than those involved in the Fund’s use of such Currency Instruments, the Fund could be disadvantaged by having to deal in the odd lot market (generally consisting of transactions of less than $1 million) for the underlying foreign currencies at prices that are less favorable than for round lots. There is no systematic reporting of last sale information for foreign currencies or any regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Quotation information generally is representative of very large transactions in the interbank market and thus might not reflect odd-lot transactions where rates might be less favorable. The interbank market in foreign currencies is a global, round-the-clock market. To the extent the U.S. options or futures markets are closed while the markets for the underlying currencies remain open, significant price and rate movements might take place in the underlying markets that cannot be reflected in the U.S. markets for the Currency Instruments until they reopen.

Settlement of hedging transactions involving foreign currencies might be required to take place within the country issuing the underlying currency. Thus, the Fund might be required to accept or make delivery of the underlying foreign currency in accordance with any U.S. or foreign regulations regarding the maintenance of foreign banking arrangements by U.S. residents and might be required to pay any fees, taxes and charges associated with such delivery assessed in the issuing country.

Forward Currency Contracts

The Fund may enter into forward currency contracts to purchase or sell foreign currencies for a fixed amount of U.S. dollars or another currency at a future date and at a price set by the parties to the forward currency contract. Forward currency contracts are traded directly between currency traders (usually large commercial banks) and their customers (such as the Fund).

The Fund may purchase a forward currency contract to lock in the U.S. dollar price of a security denominated in a foreign currency that the Fund intends to acquire (a long hedge). The Fund may sell a forward currency contract to lock in the U.S.

Table of Contents

dollar equivalent of the proceeds from the anticipated sale of a security, dividend or interest payment denominated in a foreign currency (a short hedge). A “position hedge” is when a Fund owns a security denominated in, for example, euros and to protect against a possible decline in the euro’s value, the Fund enters into a forward currency contract to sell euros in return for U.S. dollars. A “position hedge” tends to offset both positive and negative currency fluctuations but would not offset changes in security values caused by other factors. A “proxy hedge” is when a Fund owns a security denominated in, for example, euros and to protect against a possible decline in the euro’s value, the Fund enters into a forward currency contract to sell a currency expected to perform similarly to the euro in return for U.S. dollars. A “proxy hedge” could offer advantages in terms of cost, yield or efficiency, but generally would not hedge currency exposure as effectively as a position hedge to the extent the proxy currency does not perform similarly to the targeted currency. The Fund could, in fact, lose money on both legs of the hedge, i.e., between the euro and proxy currency, and between the proxy currency and the dollar. The Fund also may use forward currency contracts to attempt to enhance return or yield. The Fund could use forward currency contracts to increase its exposure to foreign currencies that the portfolio manager believes might rise in value relative to the U.S. dollar, or shift its exposure to foreign currency fluctuations from one country to another. For example, if the Fund’s portfolio manager believes that the U.S. dollar will increase in value relative to the euro, the Fund could write a forward contract to buy U.S. dollars in three months at the current price in order to sell those U.S. dollars for a profit if the U.S. dollar does in fact appreciate in value relative to the euro. The cost to the Fund of engaging in forward currency contracts varies with factors such as the currency involved, the length of the contract period and the market conditions then prevailing. Because forward currency contracts are usually entered into on a principal basis, no fees or commissions are involved. When the Fund enters into a forward currency contract, it relies on the counterparty to make or take delivery of the underlying currency at the maturity of the contract. Failure by the counterparty to do so would result in the loss of any expected benefit of the transaction.

The precise matching of forward currency contract amounts, and the value of the securities involved generally will not be possible because the value of such securities, measured in the foreign currency, will change after the forward currency contract has been established. Thus, the Fund may need to purchase or sell foreign currencies in the spot (i.e., cash) market to the extent such foreign currencies are not covered by forward currency contracts. The projection of short-term currency market movements is extremely difficult, and the successful execution of a short-term hedging strategy is highly uncertain.

Successful use of forward currency contracts depends on the portfolio manager’s skill in analyzing and predicting currency values. Forward currency contracts may substantially change the Fund’s exposure to changes in currency exchange rates and could result in losses to the Fund if currencies do not perform as the portfolio manager anticipates. There is no assurance that the portfolio manager’s use of forward currency contracts will be advantageous to the Fund or that the portfolio manager will hedge at an appropriate time.

Non-deliverable Forwards . The consummation of a deliverable foreign exchange forward requires the actual exchange of the principal amounts of the two currencies in the contract (i.e., settlement on a physical basis). Forward currency contracts in which the Fund may engage also include non-deliverable forwards (“NDFs”). NDFs are cash-settled, short-term forward contracts on foreign currencies (each a “Reference Currency”) that are non-convertible and that may be thinly traded or illiquid. NDFs involve an obligation to pay an amount equal to the difference between the prevailing market exchange rate for the Reference Currency and the agreed upon exchange rate, with respect to an agreed notional amount. NDFs are subject to many of the risks associated with derivatives in general and forward currency transactions, including risks associated with fluctuations in foreign currency and the risk that the counterparty will fail to fulfill its obligations.

Under the Dodd-Frank Act, NDFs are classified as “swaps” and are therefore subject to the full panoply of CFTC swap regulations under the Dodd-Frank Act. Although NDFs have historically been traded OTC, in the future, pursuant to the Dodd-Frank Act, they may be subject to mandatory clearing. For more information on central clearing and trading of cleared swaps, see “Swaps” below. Non-centrally-cleared NDFs are subject to mandatory minimum margin requirements for uncleared swaps. Deliverable foreign exchange forwards that solely involve the exchange of two different currencies on a specific future date at a fixed rate agreed upon by the parties are not considered “swaps” and accordingly are not subject to many of the regulations that apply to NDFs. However, as mandated by the Dodd-Frank Act and set forth in CFTC regulations adopted thereunder, foreign exchange forwards must be reported to a swap data repository, and swap dealers and major swap participants who are party to such transactions remain subject to the business conduct standards pertaining to swaps in connection with such deliverable foreign exchange forwards.

Futures Contracts and Options on Futures Contracts

Generally, a futures contract is an exchange-traded, standardized agreement that obligates the seller of the contract to deliver a specified quantity of an underlying instrument, such as a security, currency or commodity, to the purchaser of the contract, who has the obligation to take delivery of the underlying instrument, at a specified price and date. In the case of futures on indices, the two parties agree to take or make delivery of an amount of cash equal to the difference between the level of the index at the close of the last trading day of the contract and the price at which the contract originally was written. Options on futures give the purchaser the right to assume a position in a futures contract at the specified exercise price at any time during the period of the option.

Futures contracts, by their terms, have stated expirations and, at a specified point in time prior to expiration, trading in a futures contract for the current delivery month will cease. As a result, an investor wishing to maintain exposure to a futures contract with the nearest expiration must close out the position in the expiring contract and establish a new position in the contract for the next delivery month, a process referred to as “rolling.” The process of rolling a futures contract can be profitable or unprofitable depending in large part on whether the futures price for the subsequent delivery month is less than or more than the price of the expiring contract.

Futures contracts may be used for hedging and non-hedging purposes, such as to simulate full investment in the underlying instrument while retaining a cash balance for portfolio management purposes, as a substitute for direct investment in the underlying instrument, to facilitate trading, to reduce transaction costs, or to seek higher investment returns (e.g., when a futures contract or option is priced more attractively than the underlying instrument). In addition, futures strategies can be used to manage the average duration of the Fund’s fixed income portfolio, if applicable. The Fund may sell a debt futures contract or a call option thereon or purchase a put option on that futures contract to attempt to shorten the portfolio’s average duration. Alternatively, the Fund may buy a debt futures contract or a call option thereon or sell a put option thereon to attempt to lengthen the portfolio’s average duration.

At the inception of a futures contract the Fund is required to deposit “initial margin” with a futures commission merchant (“FCM”) in an amount at least equal to the amount designated by the futures exchange (typically equal to 10% or less of the contract value). Margin must also be deposited when writing a call or put option on a futures contract, in accordance with applicable exchange rules. Unlike margin in securities transactions, initial margin on futures contracts does not represent a borrowing, but rather is in the nature of a performance bond or good-faith deposit that is required to be returned to the Fund at the termination of the transaction if all contractual obligations have been satisfied. Under certain circumstances, such as periods of high volatility, the Fund may be required by an exchange to increase the level of its initial margin payment, and initial margin requirements might be increased generally in the future by regulatory action.

In addition to initial margin payments, during the life of the transaction “variation margin” payments are made to and from the FCM as the value of the margin and the underlying derivative transaction varies, a process known as “marking-to-market.” Variation margin is intended to represent a daily settlement of the Fund’s obligations to or from a FCM. When the Fund purchases an option on a futures contract, the premium paid plus transaction costs is all that is at risk. However, there may be circumstances when the purchase of an option on a futures contract would result in a loss to the Fund when the use of a futures contract would not, such as when there is no movement in the value of the securities or currencies being hedged. In that case, the Fund would lose the premium it paid for the option plus transaction costs. In contrast, when the Fund purchases or sells a futures contract or writes a call or put option thereon, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If the Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous.

Although some futures and options on futures call for making or taking delivery of the underlying instrument, generally those contracts are closed out prior to delivery by offsetting purchases or sales of matching futures or options (involving the same instrument and delivery month). If an offsetting purchase price is less than the original sale price, the Fund realizes a gain, or if it is more, the Fund realizes a loss. If an offsetting sale price is more than the original purchase price, the Fund realizes a gain, or if it is less, the Fund realizes a loss. The Fund will also bear transaction costs for each contract, which will be included in these calculations. Positions in futures and options on futures may be closed only on an exchange or board of trade that provides a secondary market. However, there can be no assurance that a liquid secondary market will exist for a particular contract at a particular time. In such event, it may not be possible to close a futures contract or options position.

Table of Contents

Under certain circumstances, futures exchanges may establish daily limits on the amount that the price of a futures contract or an option on a futures contract can vary from the previous day’s settlement price; once that limit is reached, no trades may be made that day at a price beyond the limit. Daily price limits do not limit potential losses because prices could move to the daily limit for several consecutive days with little or no trading, thereby preventing liquidation of unfavorable positions. If the Fund were unable to liquidate a futures contract or an option on a futures position due to the absence of a liquid secondary market, the imposition of price limits or otherwise, it could incur substantial losses. The Fund would continue to be subject to market risk with respect to the position. In addition, except in the case of purchased options, the Fund would continue to be required to make daily variation margin payments and might be required to maintain the position being hedged by the future or option or to segregate cash or securities (or designate these assets on its books as segregated).

Risks of Futures Contracts and Options Thereon : In addition to the risks found under “Derivatives – Risks of Derivatives Generally,” futures contracts and options on futures contracts are subject to the following risks:

Successful use of futures contracts and related options depends upon the ability of the portfolio manager to assess movements in the direction of prices of securities, commodities, measures of value, or interest or exchange rates, which requires different skills and techniques than assessing the value of individual securities. Moreover, futures contracts relate not to the current price level of the underlying instrument, but to the anticipated price level at some point in the future; accordingly trading of stock index futures may not reflect the trading of the securities that are used to formulate the index or even actual fluctuations in the index itself. There is, in addition, the risk that movements in the price of the futures contract will not correlate with the movements in the prices of the securities being hedged. Price distortions in the marketplace, resulting from increased participation by speculators in the futures market (among other things), may also impair the correlation between movements in the prices of futures contracts and movements in the prices of the hedged securities. If the price of the futures contract moves less than the price of securities that are the subject of the hedge, the hedge will not be fully effective; but if the price of the securities being hedged has moved in an unfavorable direction, the Fund would be in a better position than if it had not hedged at all. If the price of the securities being hedged has moved in a favorable direction, this advantage may be partially offset by losses on the futures position.

Positions in futures contracts may be closed out only on an exchange or board of trade that provides a market for such futures contracts. Although the Fund intends to purchase and sell futures only on exchanges or boards of trade where there appears to be a liquid market, there is no assurance that such a market will exist for any particular contract at any particular time. In such event, it may not be possible to close a futures position and, in the event of adverse price movements, the Fund would continue to be required to make variation margin payments. Options have a limited life and thus can be disposed of only within a specific time period.

Purchasers of options on futures contracts pay a premium in cash at the time of purchase which, in the event of adverse price movements, could be lost. Sellers of options on futures contracts must post initial margin and are subject to additional margin calls that could be substantial in the event of adverse price movements. Because of the low margin deposits required, futures trading involves a high degree of leverage; as a result, a relatively small price movement in a futures contract may result in immediate and substantial loss, or gain, to the Fund. In addition, the Fund’s activities in the futures markets may result in a higher portfolio turnover rate (see “Portfolio Transactions and Brokerage”) and additional transaction costs in the form of added brokerage commissions.

As noted above, exchanges may impose limits on the amount by which the price of a futures contract or related option is permitted to change in a single day. If the price of a contract moves to the limit for several consecutive days, the Fund may be unable during that time to close its position in that contract and may have to continue making payments of variation margin. The Fund may also be unable to dispose of securities or other instruments being used as “cover” during such a period. The CFTC and domestic exchanges have also established speculative position limits on the maximum speculative position that any person, or group of persons acting in concert, may hold or control in particular contracts and certain related swaps. Under current regulations, other accounts managed by the Manager or, if applicable, Subadviser are combined with the positions held by the Fund under the Manager’s or, if applicable, Subadviser’s management for position limit purposes. This trading could prelude additional trading by the Fund in such contracts.

When the Fund engages in futures transactions, it will also be exposed to the credit risk of its FCM. If the Fund’s FCM becomes bankrupt or insolvent, or otherwise defaults on its obligations to the Fund, the Fund may not receive all amounts owed to it in respect of its trading, even if the clearinghouse fully discharges all of its obligations. If an FCM were not to appropriately

17

Table of Contents

segregate client assets to the full extent required by the CEA, the Fund might not be fully protected in the event of the bankruptcy of an FCM. In the event of an FCM’s bankruptcy, the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of an FCM’s combined customer accounts, even if certain property held by an FCM is specifically traceable to the Fund (for example, U.S. Treasury bills deposited by the Fund). Such situations could arise due to various factors, or a combination of factors, including inadequate FCM capitalization, inadequate controls on customer trading and inadequate customer capital. In addition, in the event of the bankruptcy or insolvency of a clearinghouse, the Fund might experience a loss of funds deposited through its FCM as margin with the clearinghouse, a loss of unrealized profits on its open positions and the loss of funds owed to it as realized profits on closed positions. Such a bankruptcy or insolvency might also cause a substantial delay before the Fund could obtain the return of funds owed to it by an FCM who is a member of such clearinghouse.

Options

A call option gives the purchaser the right to buy, and obligates the writer to sell, an underlying investment (such as a specified security, commodity, currency, interest rate, currency exchange rate or index) at an agreed-upon price (“strike price”). A put option gives the purchaser the right to sell, and obligates the writer to buy, an underlying investment at an agreed-upon price. An American-style option may be exercised at any time during the term of the option, while a European-style option may be exercised only at the expiration of the option. Purchasers of options pay an amount, known as a premium, to the option writer in exchange for the right granted under the option contract.

The value of an option position will reflect, among other things, the current market value of the underlying instrument, the time remaining until expiration, the relationship of the strike price to the market price of the underlying instrument, the historical price volatility of the underlying instrument and general market conditions. If the purchaser does not exercise the option, it will expire and the purchaser will have only lost the premium paid. If a secondary market exists, a purchaser or the writer may terminate a put option position prior to its exercise by selling it in the secondary market at its current price. The Fund will pay a brokerage commission each time it buys or sells an option. Such commissions may be higher than those that would apply to direct purchases or sales of the underlying instrument.

Exchange-traded options in the United States are issued by a clearing organization affiliated with the exchange on which the option is listed and are standardized with respect to the underlying instrument, expiration date, contract size and strike price. In contrast, OTC options (options not traded on exchanges) are contracts between the Fund and a counterparty (usually a securities dealer or a bank) with no clearing organization guarantee. The terms of OTC options generally are established through negotiation with the other party to the option contract (the counterparty). For a discussion on options on swaps, see “ Swaps – Options on Swaps .” For a discussion on options on futures see “ Futures Contracts and Options on Futures Contracts ”.

Put Options . In return for receipt of the premium, the writer of a put option assumes the obligation to pay the strike price for the option’s underlying instrument if the buyer exercises the option. A put writer would generally expect to profit, although its gain would be limited to the amount of the premium it received, if the underlying instrument’s price remains greater than or equal to the strike price. If the underlying instrument’s price falls below the strike price, the put writer would expect to suffer a loss. The buyer of a put option can expect to realize a gain if the underlying instrument’s price falls enough to offset the cost of purchasing the option. Any losses suffered by the buyer would be limited to the amount of the premium plus related transaction costs.

Optional delivery standby commitments are a type of put that gives the buyer of an underlying instrument the right to sell the underlying instrument back to the seller on specified terms to induce a purchase of the underlying instrument.

Call Options . In return for the receipt of the premium, the writer of a call option assumes the obligation to sell the underlying instrument at the strike price to the buyer upon exercise of the option. A call writer would generally expect to profit, although its gain would be limited to the amount of the premium it received, if the option goes unexercised, which typically occurs when the underlying instrument’s price remains less than or equal to the strike price. If the underlying instrument’s prices were to rise above the strike price, the writer of the call option would generally expect to suffer a loss, which is theoretically unlimited. A call buyer’s maximum loss is the premium paid for the call option, whereas the buyer’s maximum profit is theoretically unlimited.

Straddles . A long straddle is the purchase of a call and a put option with the same expiration date and relating to the same underlying instrument where the strike price of the put is less than or equal to the strike price of the call. The Fund may enter into a long straddle when its portfolio manager believes that the underlying instrument’s price will move significantly

18

Table of Contents

during the term of the options. A short straddle is a combination of a call and a put written on the same underlying instrument with the same expiration date where the strike price of the put is less than or equal to the strike price of the call. In a covered short straddle, the underlying instrument is considered cover for both the put and the call that the Fund has written. The Fund may enter into a short straddle when the portfolio manager believes that it is unlikely that underlying instrument’s prices will experience volatility during the term of the options.

Options on Indices . Puts and calls on indices are similar to puts and calls on other underlying instruments except that all settlements are in cash and gains or losses depend on changes in the level of the index rather than on price movements of individual underlying instruments. The writer of a call on an index receives a premium and the obligation to pay the purchaser an amount of cash equal to the difference between the closing level of the index and the strike price times a specified multiple (“multiplier”), if the closing level of the index is greater than the strike price of the call. The writer of a put on an index receives a premium and the obligation to deliver to the buyer an amount of cash equal to the difference between the closing level of the index and strike price times the multiplier if the closing level is less than the strike price.

Risks of Options – In addition to the risks described under “ Derivatives – Risks of Derivatives Generally ,” options are also subject to the following risks:

Options on Indices Risk . The risks of investment in options on indices may be greater than options on securities and other instruments. Because index options are settled in cash, when the Fund writes a call on an index it generally cannot provide in advance for other underlying instruments because it may not be practical for the call writer to hedge its potential settlement obligations by acquiring and holding the underlying securities. The Fund can offset some of the risk of writing a call index option by holding a diversified portfolio of securities similar to those on which the underlying index is based. However, the Fund cannot, as a practical matter, acquire and hold a portfolio containing exactly the same securities as underlie the index and, as a result, bears a risk that the value of the securities held will vary from the value of the index.

If the Fund exercises an index option before the closing index value for that day is available, there is the risk that the level of the underlying index may subsequently change. If such a change causes the exercised option to fall out-of-the-money, the Fund will be required to pay the difference between the closing index value and the strike price of the option (times the applicable multiplier) to the assigned writer.

Timing Risk . The hours of trading for options may not conform to the hours during which the underlying instrument are traded. To the extent that the options markets close before the markets for the underlying instrument, significant price and rate movements can take place in the underlying markets that cannot be reflected in the options markets. Options are marked to market daily and their value will be affected by changes in the value of the underlying instrument, changes in the dividend rates of the underlying securities, an increase in interest rates, changes in the actual or perceived volatility of the stock market and the underlying instrument and the remaining time to the options’ expiration. Additionally, the exercise price of an option may be adjusted downward before the option’s expiration as a result of the occurrence of certain corporate or other events affecting the underlying instrument, such as extraordinary dividends, stock splits, merger or other extraordinary distributions or events. A reduction in the exercise price of an option would reduce the Fund’s capital appreciation potential on an underlying instrument.

Swaps

Generally, a swap agreement involves the exchange between two parties of their respective commitments to pay or receive cash flows, e.g., an exchange of floating rate payments for fixed-rate payments. Swaps may be negotiated bilaterally and traded OTC (OTC swaps) or, for certain types of swaps, must be executed through a centralized exchange or regulated facility and be cleared through a regulated clearinghouse (cleared swaps). Swaps include but are not limited to, interest rate swaps, total return swaps, index swaps, inflation indexed swaps, currency swaps, credit default swaps and options on swaps or “swaptions”.

OTC swap agreements can be individually negotiated and structured to include exposure to a variety of different types of investments (such as individual securities, baskets of securities and securities indices) or market factors. The swapped returns are generally calculated with respect to a notional amount, that is, the nominal or face amount used to calculate the payments to be made between the parties to the OTC swap.

The Fund may enter into a swap agreement for hedging or non-hedging purposes, including but not limited to, to enhance returns, increase liquidity, protect against currency and security price fluctuations, manage duration and gain exposure to certain markets or securities in a more cost-efficient manner.

19

Table of Contents

When the Fund enters into a swap agreement on a net basis, the net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each swap will be accrued on a daily basis and an amount of cash, cash equivalent or liquid assets having an aggregate market value at least equal to the accrued excess will be segregated in an account with the Fund’s custodian that satisfies the requirements of the 1940 Act. The Fund will take similar action with respect to its total obligations under any swaps that are not entered into on a net basis and with respect to any caps or floors that are written by the Fund. See “Interest Rate Swaps, Caps and Floors” below.

Risks of Swaps Generally. In addition to the risks found under “Derivatives – Risks of Derivatives Generally,” swaps are subject to the following risks:

Depending on their structure, swap agreements may increase or decrease the overall volatility of the Fund’s investments and its share price and yield and may affect the Fund’s exposure to long- or short-term interest rates (in the United States or abroad), foreign currency values, mortgage-backed security values, corporate borrowing rates or other market factors such as security prices or inflation rates.

Swap agreements will tend to shift the Fund’s investment exposure from one type of investment to another. For example, if the Fund agrees to exchange payments in U.S. dollars for payments in foreign currency, the swap agreement would tend to decrease the Fund’s exposure to U.S. interest rates and increase its exposure to foreign currency and interest rates.

The swap market is a relatively new market and is largely unregulated. The absence of a central exchange or market for swap transactions may lead, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions.

Cleared Swaps. Recent legislation and implementing regulation require certain swaps to be cleared through a regulated clearinghouse. Although this clearing mechanism is generally intended to reduce counterparty credit risk, it may disrupt or limit the swap market and may result in swaps being more difficult to trade or value. As swaps become more standardized, the Fund may not be able to enter into swaps that meet its investment needs. The Fund also may not be able to find a clearinghouse willing to accept a swap for clearing. In a cleared swap, a central clearing organization will be the counterparty to the transaction. The Fund will assume the risk that the clearinghouse may be unable to perform its obligations.

When the Fund enters into a cleared swap transaction, the Fund is subject to the credit and counterparty risk of the clearing house and the clearing member through which it holds its cleared position. Credit/counterparty risk of market participants with respect to centrally cleared swaps is concentrated in a few clearing houses, and it is not clear how an insolvency proceeding of a clearing house would be conducted and what impact an insolvency of a clearing house would have on the financial system. A clearing member is obligated by contract and by applicable regulation to segregate all funds received from customers with respect to cleared derivatives transactions from the clearing member’s proprietary assets. However, all funds and other property received by a clearing broker from its customers generally are held by the clearing broker on a commingled basis in an omnibus account, and the clearing member may invest those funds in certain instruments permitted under the applicable regulations. The assets of the Fund might not be fully protected in the event of the bankruptcy of the Fund’s clearing member, because the Fund would be limited to recovering only a pro rata share of all available funds segregated on behalf of the clearing broker’s customers for a relevant account class. Also, the clearing member is required to transfer to the clearing organization the amount of margin required by the clearing organization for cleared derivatives, which amounts generally are held in an omnibus account at the clearing organization for all customers of the clearing member. Regulations promulgated by the CFTC require that the clearing member notify the clearing house of the amount of initial margin provided by the clearing member to the clearing organization that is attributable to each customer. However, if the clearing member does not provide accurate reporting, the Fund is subject to the risk that a clearing organization will use the Fund’s assets held in an omnibus account at the clearing organization to satisfy payment obligations of a defaulting customer of the clearing member to the clearing organization. In addition, clearing members generally provide to the clearing organization the net amount of variation margin required for cleared swaps for all of its customers in the aggregate, rather than the gross amount of each customer. The Fund is therefore subject to the risk that a clearing organization will not make variation margin payments owed to the Fund if another customer of the clearing member has suffered a loss and is in default, and the risk that the Fund will be required to provide additional variation margin to the clearing house before the clearing house will move the Fund’s cleared derivatives transactions to another clearing member. In addition, if a clearing member does not comply with the applicable regulations or its agreement with the Fund, or in the event of fraud or misappropriation of customer assets by a clearing member, the Fund could

20

Table of Contents

have only an unsecured creditor claim in an insolvency of the clearing member with respect to the margin held by the clearing member.

In some ways, centrally cleared swaps arrangements are less favorable to the Fund than OTC swaps arrangements. For example, the Fund may be required to provide greater amounts of margin for cleared swaps than for OTC swaps. Also, in contrast to OTC swaps, following a period of notice to the Fund, a clearing member generally can require termination of existing cleared swaps at any time or increases in margin requirements above the margin that the clearing member required at the beginning of a transaction. Clearing houses also have broad rights to increase margin requirements for existing transactions or to terminate transactions at any time. Any increase in margin requirements or termination by the clearing member or the clearing house could interfere with the ability of the Fund to pursue its investment strategy. Further, any increase in margin requirements by a clearing member could also expose the Fund to greater credit risk of its clearing member, because margin for cleared swaps in excess of clearing house margin requirements typically is held by the clearing member. While the documentation in place between the Fund and its clearing members generally provides that the clearing members will accept for clearing all transactions submitted for clearing that are within credit limits (specified in advance) for the Fund, the Fund is still subject to the risk that no clearing member will be willing or able to clear a transaction. In those cases, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of the transaction, including loss of an increase in the value of the transaction and/or loss of hedging protection offered by the transaction. In addition, the documentation governing the relationship between the Fund and its clearing members is developed by the clearing members and generally is less favorable to the Fund than typical OTC swap documentation. For example, this documentation generally includes a one-way indemnity by the Fund in favor of the clearing member, indemnifying the clearing member against losses it incurs in connection with acting as the Fund’s clearing member, and the documentation typically does not give the Fund any rights to exercise remedies if the clearing member defaults or becomes insolvent.

Some types of cleared swaps are required to be executed on an exchange or on a swap execution facility (“SEF”). A SEF is a trading platform where multiple market participants can execute swaps by accepting bids and offers made by multiple other participants in the platform. While this execution requirement is designed to increase transparency and liquidity in the cleared swap market, trading on a SEF can create additional costs and risks for the Fund. For example, SEFs typically charge fees, and if the Fund executes swaps on a SEF through a broker intermediary, the intermediary may impose fees as well. Also, the Fund may indemnify a SEF, or a broker intermediary who executes cleared swaps on a SEF on the Fund’s behalf, against any losses or costs that may be incurred as a result of the Fund’s transactions on the SEF.

The Fund may enter into swap transactions with certain counterparties pursuant to master netting agreements. A master netting agreement provides that all swaps entered into between the Fund and that counterparty shall be regarded as parts of an integral agreement. If amounts are payable on a particular date in the same currency in respect of more than one swap transaction, the amount payable shall be the net amount. In addition, the master netting agreement may provide that if one party defaults generally or on any swap, the counterparty can terminate all outstanding swaps with that party. As a result, to the extent the Fund enters into master netting agreements with a counterparty, the Fund may be required to terminate a greater number of swap agreements than if it had not entered into such an agreement, which may result in losses to the Fund.

Interest Rate Swaps, Caps and Floors. Interest rate swaps are agreements between two parties to exchange interest rate payment obligations. Typically, one party’s obligation is based on a fixed interest rate while the other party’s obligation is based on an interest rate that fluctuates with changes in a designated benchmark. An interest rate cap transaction entitles the purchaser, to the extent that a specified index exceeds a predetermined value, to receive payments on a notional principal amount from the party selling the cap. An interest rate floor transaction entitles the purchaser, to the extent that a specified index falls below a predetermined value, to receive payments on a notional principal amount from the party selling the floor. A collar combines elements of buying a cap and a floor. Caps and floors have an effect similar to buying or writing options. Caps and floors are typically less liquid than swaps.

Options on Swaps (“Swaptions”). A swaption is a contract that gives the counterparty the right, but not the obligation to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may write (sell) and purchase put and call swaptions. Swaptions are generally subject to the same risks involved in the use of options and swaps. Depending on the terms of the option agreement, the Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, only the amount of premium the Fund paid is at risk should the option expire unexercised.

21

Table of Contents

However, when a Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement, which may result in losses to the Fund in excess of the premium it received.

Credit Default Swaps and Related Investments. The Fund may enter into credit default swap contracts for investment purposes and to add leverage to its investment portfolio. As the seller in a credit default swap contract, the Fund would be required to pay the par (or other agreed-upon) value of a debt-reference obligation to the counterparty in the event of a default by a third party on the debt obligation. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its net assets, the Fund would be subject to investment exposure on the swap. Credit default swap contracts involve special risks and may result in losses to the Fund. Credit default swaps may in some cases be illiquid, and they increase credit risk since the Fund has exposure to both the issuer of the referenced obligation and the counterparty to the credit default swap. As there is no central exchange or market for certain credit default swap transactions, they may be difficult to trade or value, especially in the event of market disruptions. It is possible that developments in the swap market, including new or modified government regulation, could adversely affect the Fund’s ability to terminate existing credit default swap agreements or to realize amounts to be received under such agreements.

A Fund may also purchase credit default swap contracts to attempt to hedge against the risk of default of debt securities held in its portfolio, in which case the Fund would function as the counterparty referenced in the preceding paragraph. This would involve the risk that the investment may expire worthless and would only generate income in the event of an actual default by the issuer of the underlying obligation (or, as applicable, a credit downgrade or other indication of financial instability). It would also involve credit risk—that the seller may fail to satisfy its payment obligations to the Fund in the event of a default.

The Fund may invest in credit default swap index products that provide exposure to multiple credit default swaps. The Fund can either buy the index (take on credit exposure) or sell the index (pass credit exposure to a counterparty). Such investments are subject to the associated risks with investments in credit default swaps discussed above.

Equity-Linked Notes (“ELNs”)

ELNs are securities that are valued based upon the performance of one or more equity securities, such as a stock index, a group of stocks or a single stock. ELNs offer the opportunity to participate in the appreciation of the underlying local equity securities where the Fund may not have established local market access. Investments in ELNs are subject to risk of loss of principal investment.

Equity Securities

Equity securities include exchange-traded and over-the-counter common and preferred stocks, warrants and rights, and securities convertible into common stocks. Equity securities fluctuate in price based on changes in a company’s financial condition and overall market and economic conditions. The value of a particular security may decline due to factors that affect a particular industry or industries, such as an increase in production costs, competitive conditions or labor shortages; or due to general market conditions, such as real or perceived adverse economic conditions, changes in the general outlook for corporate earnings, changes in interest or currency rates or generally adverse investor sentiment. The value of an equity security can be more volatile than the market as a whole and can perform differently from the value of the market as a whole. The value of a company’s equity securities may deteriorate because of a variety of factors, including disappointing earnings reports by the issuer, unsuccessful products or services, loss of major customers, major litigation against the issuer or changes in government regulations affecting the issuer or the competitive environment.

Exchange Traded Funds (“ETFs”)

ETFs are ownership interests in investment companies, unit investment trusts, depositary receipts and other pooled investment vehicles that are traded on an exchange and that hold a portfolio of securities or other financial instruments (the “Underlying Assets”). The Underlying Assets are typically selected to correspond to the securities that comprise a particular broad based sector or international index, or to provide exposure to a particular industry sector or asset class, including precious metals or other commodities. “Short ETFs” seek a return similar to the inverse, or a multiple of the inverse, of a reference index. Short ETFs carry additional risks because their Underlying Assets may include a variety of financial instruments, including futures and options on futures, options on securities and securities indexes, swap agreements and forward contracts, and a short ETF

22

Table of Contents

may engage in short sales. An ETF’s losses on short sales are potentially unlimited; however, the Fund’s risk would be limited to the amount it invested in the ETF. Certain ETFs are actively managed by a portfolio manager or management team that makes investment decisions on Underlying Assets without seeking to replicate the performance of a reference index or industry sector or asset class.

Unlike shares of typical open-end management investment companies or unit investment trusts, shares of ETFs are designed to be traded throughout the trading day and bought and sold based on market price rather than net asset value. Shares can trade at either a premium or discount to net asset value. The portfolios held by ETFs are typically publicly disclosed on each trading day and an approximation of actual net asset value is disseminated throughout the trading day. Because of this transparency, the trading prices of ETFs tend to closely track the actual net asset value of the Underlying Assets and the ETF will generally gain or lose value depending on the performance of the Underlying Assets. In the future, as new products become available, the Fund may invest in ETFs that do not have this same level of transparency and, therefore, may be more likely to trade at a larger discount or premium to actual net asset values.

Gains or losses on the Fund’s investment in ETFs will ultimately depend on the purchase and sale price of the ETF. An active trading market for an ETF’s shares may not develop or be maintained and trading of an ETF’s shares may be halted if the listing exchange’s officials deem such action appropriate, the shares are delisted from the exchange or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts stock trading generally. The performance of an ETF will be reduced by transaction and other expenses, including fees paid by the ETF to service providers. Investors in ETFs are eligible to receive their portion of income, if any, accumulated on the securities held in the portfolio, less fees and expenses of the ETF.

An investment in an ETF involves risks similar to investing directly in the Underlying Assets, including the risk that the value of the Underlying Assets may fluctuate in accordance with changes in the financial condition of their issuers, the value of securities and other financial instruments generally, and other market factors.

If an ETF is a registered investment company (as defined in the 1940 Act), the limitations applicable to the Fund’s ability to purchase securities issued by other investment companies apply absent exemptive relief. The SEC has granted orders for exemptive relief to certain ETFs that permit investments in those ETFs by other investment companies (such as the Fund) in excess of these limits. Under the orders, other investment companies generally may acquire up to 25% of the assets of an ETF. Some ETFs are not structured as investment companies and thus are not regulated under the 1940 Act.

Exchange Traded Notes (“ETNs”)

ETNs are senior, unsecured, unsubordinated debt securities issued by a bank or other financial institution whose returns are linked to the performance of a one or more assets, reference rates or index, minus applicable fees. ETNs are publicly traded on a securities exchange but can also be held until maturity. At maturity, the issuer pays to the investor a cash amount linked to the performance of the specific asset, rate or index to which the ETN is linked minus certain fees.

ETNs do not make periodic coupon payments or provide principal protection. ETNs are subject to credit risk and the value of the ETN may drop due to a downgrade in the issuer’s credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political or geographic events that affect the referenced underlying asset. There may be times when an ETN trades at a premium or discount to its net asset value. When the Fund invests in ETNs it will bear its proportionate share of any fees and expenses borne by the ETN. These fees and expenses generally reduce the return realized at maturity or upon redemption from an investment in an ETN; therefore, the value of the index underlying the ETN must increase significantly in order for an investor in an ETN to receive at least the principal amount of the investment at maturity or upon redemption. The Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market or restrictions on the right to redeem its investment in an ETN.

ETNs are also subject to tax risk. The tax rules are uncertain with respect to the treatment of income or gains arising in respect of commodity-linked ETNs and certain commodity-linked structured notes; also, the timing and character of income or gains arising from ETNs can be uncertain. The IRS and Congress are considering proposals that would change the timing and character of income and gains from ETNs. An adverse determination or future guidance by the IRS with respect to the treatment

of ETNs (which determination or guidance could be retroactive) may affect the Fund’s ability to qualify for treatment as a RIC and to avoid a fund-level tax.

Foreign Securities

The risks of investing in securities of non-U.S. issuers or issuers with significant exposure to non-U.S. markets may be related, among other things, to (i) differences in size, liquidity and volatility of, and the degree and manner of regulation of, the securities markets of certain non-U.S. markets compared to the securities markets in the U.S.; (ii) economic, political and social factors; and (iii) foreign exchange matters, such as restrictions on the repatriation of capital, fluctuations in exchange rates between the U.S. dollar and the currencies in which the Fund’s portfolio securities are quoted or denominated, exchange control regulations and costs associated with currency exchange. The political and economic structures in certain foreign countries, particularly emerging markets, are expected to undergo significant evolution and rapid development, and such countries may lack the social, political and economic stability characteristic of more developed countries.

Unanticipated political or social developments may affect the values of the Fund’s investments in such countries. The economies and securities and currency markets of many emerging markets have experienced significant disruption and declines. There can be no assurances that these economic and market disruptions will not continue.

Legal remedies available to investors in certain foreign countries may be less extensive than those available to investors in the U.S. or other foreign countries. Accounting standards in other countries are also not necessarily the same as in the United States. If the accounting standards in another country do not require as much detail as U.S. accounting standards, it may be harder for the portfolio manager to completely and accurately determine a company’s financial condition. In addition, the U.S. Government has from time to time in the past imposed restrictions, through penalties and otherwise, on foreign investments by U.S. investors such as the Fund. Also, brokerage commissions and other costs of buying or selling securities often are higher in foreign countries than they are in the U.S. This reduces the amount the Fund can earn on its investments.

The Fund generally holds its foreign securities and cash in foreign banks and securities depositories. Some foreign banks and securities depositories may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank or depository or issuer of a security or any of their agents goes bankrupt. In addition, it is often more expensive for the Fund to buy, sell and hold securities in certain foreign markets than in the U.S. The increased expense of investing in foreign markets reduces the amount the Fund can earn on its investments and typically results in a higher operating expense ratio for the Fund as compared to investment companies that invest only in the United States.

Securities of some foreign companies are less liquid, and their prices are more volatile, than securities of comparable domestic companies. Certain foreign countries are known to experience long delays between the trade and settlement dates of securities purchased or sold resulting in increased exposure of the Fund to market and foreign exchange fluctuations brought about by such delays, and to the corresponding negative impact on Fund liquidity.

Foreign Currency Risks

The U.S. dollar value of securities denominated in a foreign currency will vary with changes in currency exchange rates, which can be volatile. Accordingly, changes in the value of the currency in which the Fund’s investments are denominated relative to the U.S. dollar will affect the Fund’s net asset value. Exchange rates are generally affected by the forces of supply and demand in the international currency markets, the relative merits of investing in different countries and the intervention or failure to intervene of U.S. or foreign governments and central banks. However, currency exchange rates may fluctuate based on factors intrinsic to a country’s economy. Some emerging market countries also may have managed currencies, which are not free floating against the U.S. dollar. In addition, emerging markets are subject to the risk of restrictions upon the free conversion of their currencies into other currencies. Any devaluations relative to the U.S. dollar in the currencies in which the Fund’s securities are quoted would reduce the Fund’s net asset value per share.

Investment in Emerging Markets

Investors are strongly advised to consider carefully the special risks involved in emerging markets, which are in addition to the usual risks of investing in developed foreign markets around the world.

24

Table of Contents

The risks of investing in securities in emerging countries include: (i) less social, political and economic stability; (ii) the smaller size of the markets for such securities and lower volume of trading, which result in a lack of liquidity and in greater price volatility; (iii) certain national policies that may restrict the Fund’s investment opportunities, including restrictions on investment in issuers or industries deemed sensitive to national interests; (iv) foreign taxation; (v) the absence of developed structures governing private or foreign investment or allowing for judicial redress for injury to private property; and (vi) military unrest, war and terrorism.

Investors should note that upon the accession to power of authoritarian regimes, the governments of a number of emerging market countries previously expropriated large quantities of real and personal property similar to the property which may be represented by the securities purchased by the Fund. The claims of property owners against those governments were never finally settled. There can be no assurance that any property represented by securities purchased by the Fund will not also be expropriated, nationalized, or otherwise confiscated at some time in the future. If such confiscation were to occur, the Fund could lose a substantial portion or all of its investments in such countries. The Fund’s investments would similarly be adversely affected by exchange control regulation in any of those countries.

Certain countries in which the Fund may invest may have vocal minorities that advocate radical religious or revolutionary philosophies or support ethnic independence. Any disturbance on the part of such individuals could carry the potential for widespread destruction or confiscation of property owned by individuals and entities foreign to such country and could cause the loss of the Fund’s investment in those countries.

Settlement mechanisms in emerging market securities may be less efficient and reliable than in more developed markets. In such emerging securities markets there may be delays and failures in share registration and delivery. In certain markets there have been times when settlements have been unable to keep pace with the volume of securities transactions, making it difficult to conduct such transactions. The inability of the Fund to make intended securities purchases due to settlement problems could cause the Fund to miss attractive investment opportunities. Inability to dispose of a portfolio security caused by settlement problems could result either in losses to the Fund due to subsequent declines in the value of the portfolio security or, if the Fund has entered into a contract to sell the security, in possible liability to the purchaser. There may also be a danger that, because of uncertainties in the operation of settlement systems in individual markets, competing claims may arise in respect of securities held by or to be transferred to the Fund. Furthermore, compensation schemes may be non-existent, limited or inadequate to meet the Fund’s claims in any of these events.

Inflation and rapid fluctuations in inflation rates have had, and may continue to have, very negative effects on the economies and securities markets of certain emerging markets. While some emerging market countries have sought to develop a number of corrective mechanisms to reduce inflation or mitigate its effects, inflation may continue to have significant effects both on emerging market economies and their securities markets. In addition, many of the currencies of emerging market countries have experienced steady devaluations relative to the U.S. dollar and major devaluations have occurred in certain countries. Economies in emerging markets generally are heavily dependent upon international trade and, accordingly, have been and may continue to be affected adversely by economic conditions, trade barriers, exchange controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

Because of the high levels of foreign-denominated debt owed by many emerging market countries, fluctuating exchange rates can significantly affect the debt service obligations of those countries. This could, in turn, affect local interest rates, profit margins and exports, which are a major source of foreign exchange earnings.

To the extent an emerging market country faces a liquidity crisis with respect to its foreign exchange reserves, it may increase restrictions on the outflow of any foreign exchange. Repatriation is ultimately dependent on the ability of the Fund to liquidate its investments and convert the local currency proceeds obtained from such liquidation into U.S. dollars. Where this conversion must be done through official channels (usually the central bank or certain authorized commercial banks), the ability to obtain U.S. dollars is dependent on the availability of such U.S. dollars through those channels and, if available, upon the willingness of those channels to allocate those U.S. dollars to the Fund. The Fund’s ability to obtain U.S. dollars may be adversely affected by any increased restrictions imposed on the outflow of foreign exchange. If the Fund is unable to repatriate any amounts due to exchange controls, it may be required to accept an obligation payable at some future date by the central bank or other governmental entity of the jurisdiction involved. If such conversion can legally be done outside official channels, either directly or indirectly, the Fund’s ability to obtain U.S. dollars may not be affected as much by any increased restrictions except to

25

Table of Contents

the extent of the price which may be required to be paid in U.S. dollars. Furthermore, repatriation of investment income, capital and the proceeds of sales by foreign investors may require governmental registration and/or approval in some countries.

Many emerging market countries have little experience with the corporate form of business organization and may not have well-developed corporation and business laws or concepts of fiduciary duty in the business context. The Fund may encounter substantial difficulties in obtaining and enforcing judgments against individuals and companies located in certain emerging market countries. It may be difficult or impossible to obtain or enforce legislation or remedies against governments, their agencies and sponsored entities.

Disclosure and regulatory standards in emerging markets in many respects are less stringent than in the United States and other major markets. There also may be a lower level of monitoring and regulation of emerging markets and the activities of investors in such markets; enforcement of existing regulations has been extremely limited.

Trading in the securities of emerging markets presents additional credit and financial risks. The Fund may have limited access to, or there may be a limited number of, potential counterparties that trade in the securities of emerging market issuers. Governmental regulations may restrict potential counterparties to certain financial institutions located or operating in the particular emerging market. Potential counterparties may not possess, adopt or implement creditworthiness standards, financial reporting standards or legal and contractual protections similar to those in developed markets. Currency hedging techniques may not be available or may be limited. The Fund may not be able to reduce or mitigate risks related to trading with emerging market counterparties.

The risk also exists that an emergency situation may arise in one or more emerging markets as a result of which trading of securities may cease or may be substantially curtailed and prices for the Fund’s portfolio securities in such markets may not be readily available. Section 22(e) of the 1940 Act permits a registered investment company to suspend redemption of its shares for any period during which an emergency exists, as determined by the SEC. Accordingly, if the Fund believes that appropriate circumstances warrant, it may apply to the SEC for a determination that an emergency exists within the meaning of Section 22(e) of the 1940 Act. During the period commencing from the Fund’s identification of such conditions until the date of SEC action, the portfolio securities in the affected markets will be valued at fair value as determined in good faith by or under the direction of the Board.

Although it might be theoretically possible to hedge for anticipated income and gains, the ongoing and indeterminate nature of the risks associated with emerging market investing (and the costs associated with hedging transactions) makes it very difficult to hedge effectively against such risks.

Europe — Recent Events

A number of countries in Europe have experienced severe economic and financial difficulties. Many non-governmental issuers, and even certain governments, have defaulted on, or been forced to restructure, their debts; many other issuers have faced difficulties obtaining credit or refinancing existing obligations; financial institutions have in many cases required government or central bank support, have needed to raise capital, and/or have been impaired in their ability to extend credit; and financial markets in Europe and elsewhere have experienced extreme volatility and declines in asset values and liquidity. These difficulties may continue, worsen or spread within and outside of Europe. Responses to the financial problems by European governments, central banks and others, including austerity measures and reforms, may not work, may result in social unrest and may limit future growth and economic recovery or have other unintended consequences.

Further defaults or restructurings by governments and others of their debt could have additional adverse effects on economies, financial markets and asset valuations around the world. In addition, on June 23, 2016, voters in the United Kingdom approved withdrawal from the European Union. On March 29, 2017, the United Kingdom formally notified the European Council of its intention to leave the European Union; as a result, the United Kingdom will remain a member state, subject to European Union law with privileges to provide services under the single market directives, for at least two years from that date. Given the size and importance of the United Kingdom’s economy, uncertainty about its legal, political, and economic relationship with the remaining member states of the European Union may continue to be a source of instability. Moreover, other countries may seek to withdraw from the European Union and/or abandon the euro, the common currency of the European Union. A number of countries in Europe have suffered terror attacks, and additional attacks may occur in the future. Ukraine has experienced ongoing military conflict; this conflict may expand and military attacks could occur elsewhere in Europe. Europe has also been struggling with mass migration from the Middle East and Africa.

26

Table of Contents

The ultimate effects of these events and other socio-political or geopolitical issues are not known but could profoundly affect global economies and markets. Whether or not the Fund invests in securities of issuers located in Europe or with significant exposure to European issuers or countries, these events could negatively affect the value and liquidity of the Fund’s investments.

Eurodollar or Yankee Obligations

Eurodollar bank obligations are U.S. dollar denominated debt obligations issued outside the U.S. capital markets by non-U.S. branches of U.S. banks and by non-U.S. banks. Yankee obligations are U.S. dollar denominated obligations issued in the U.S. capital markets by non-U.S. issuers. Eurodollar (and to a limited extent, Yankee) obligations are subject to certain sovereign risks. One such risk is the possibility that a non-U.S. government might prevent U.S. dollar denominated funds from flowing across its borders. Other risks include: adverse political and economic developments in a non-U.S. country; the extent and quality of government regulation of financial markets and institutions; the imposition of non-U.S. withholding taxes; and expropriation or nationalization of non-U.S. issuers.

Sovereign Government and Supranational Debt Obligations

The Fund may invest in all types of debt securities of governmental issuers in all countries, including emerging markets. These sovereign debt securities may include: debt securities issued or guaranteed by governments, governmental agencies or instrumentalities and political subdivisions located in emerging market countries; debt securities issued by government owned, controlled or sponsored entities located in emerging market countries; interests issued for the purpose of restructuring the investment characteristics of instruments issued by any of the above issuers; Brady Bonds, which are debt securities issued under the framework of the Brady Plan as a means for debtor nations to restructure their outstanding external indebtedness; participations in loans between emerging market governments and financial institutions; or debt securities issued by supranational entities such as the World Bank. A supranational entity is a bank, commission or company established or financially supported by the national governments of one or more countries to promote reconstruction or development. Included among these entities are the Asian Development Bank, the European Union, the European Investment Bank, the Inter-American Development Bank, the International Monetary Fund, the United Nations, the World Bank and the European Bank for Reconstruction and Development. Supranational organizations have no taxing authority and are dependent on their members for payments of interest and principal. There is no guarantee that one or more members of a supranational organization will continue to make capital contributions. If such contributions are not made, the organization may be unable to pay interest or repay principal on its debt securities, and the Fund may lose money on such investments. Further, the lending activities of such entities are limited to a percentage of their total capital, reserves and net income.

Sovereign debt is subject to risks in addition to those relating to non-U.S. investments generally. As a sovereign entity, the issuing government may be immune from lawsuits in the event of its failure or refusal to pay the obligations when due. The debtor’s willingness or ability to repay in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign currency reserves, the availability of sufficient foreign currency exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders and the political constraints to which the sovereign debtor may be subject. Sovereign debtors may also be dependent on disbursements or assistance from foreign governments or multinational agencies, the country’s access to trade and other international credits, and the country’s balance of trade. Assistance may be dependent on a country’s implementation of austerity measures and reforms, economic performance and/or the timely service of such debtor’s obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties’ commitments to lend funds to the governmental entity, which may further impair such debtor’s ability or willingness to service its debts in a timely manner. Some sovereign debtors have rescheduled their debt payments, declared moratoria on payments or restructured their debt to effectively eliminate portions of it, and similar occurrences may happen in the future. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

Depositary Receipts

Depositary receipts demonstrate ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign security. Depositary receipts may be sponsored or unsponsored and include American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”), European Depositary Receipts (“EDRs”) and non-voting depositary receipts

27

Table of Contents

(“NVDRs”). ADRs in registered form are typically issued by a U.S. bank or trust company, traded in U.S. dollars, and are designed for use in the domestic market. GDRs, EDRs, NVDRs and other similar instruments may be issued by a U.S. or non-U.S. entity and may be traded in other currencies. GDRs are tradable both in the United States and Europe and are designed for use throughout the world. EDRs are issued in bearer form and are designed for use in European securities markets.

Depositary receipts in general are subject to many of the risks associated with foreign investing (e.g., increased market, liquidity, currency, political, information and other risks), and even where traded in U.S. dollars are subject to currency risk if the underlying security is traded in a foreign currency. Unsponsored depositary receipts are issued without the participation of the issuer of the underlying foreign security and there may be less information available about such issuers than there is with respect to domestic companies and issuers of securities underlying sponsored depositary receipts. Even if there is information available, there may not be a correlation between such information and the market value of the depositary receipts.

High Yield (“Junk”) Bonds

High yield securities are medium or lower rated securities and unrated securities of comparable quality, sometimes referred to as “high yield” or “junk” bonds. Generally, such securities offer a higher current yield than is offered by higher rated securities, but also are predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal in accordance with the terms of the securities. The market values of certain of these securities also tend to be more sensitive to individual corporate developments and changes in economic conditions than higher quality bonds. In addition, medium and lower rated securities and comparable unrated securities generally present a higher degree of credit risk. The risk of loss because of default by issuers of these securities is significantly greater because medium and lower rated securities generally are unsecured and frequently subordinated to senior indebtedness. In addition, the market value of securities in lower rated categories is generally more volatile than that of higher quality securities, and the markets in which medium and lower rated securities are traded are more limited than those in which higher rated securities are traded. The existence of limited markets may make it more difficult for the Fund to obtain accurate market quotations for purposes of valuing its securities and calculating its net asset value. Moreover, the lack of a liquid trading market may restrict the availability of securities for the Fund to purchase and may also limit the ability of the Fund to sell securities at their fair value either to meet redemption requests or to respond to changes in the economy or the financial markets.

Lower rated debt obligations often have redemption features that permit an issuer to repurchase the security from the Fund before it matures. If an issuer exercises that right, the Fund may have to replace the security with a lower yielding security, resulting in a decreased return for investors. If the Fund experiences unexpected net redemptions, it may be forced to sell its higher rated bonds, resulting in a decline in the overall credit quality of the securities held by the Fund and increasing the exposure of the Fund to the risks of lower rated securities. Investments in lower rated zero coupon bonds may be more speculative and subject to greater fluctuations in value because of changes in interest rates than lower rated bonds that pay interest currently.

Subsequent to its purchase by the Fund, an issue of securities may cease to be rated or its rating may be reduced below the minimum required for purchase by the Fund (if applicable). Neither event will require sale of these securities by the Fund, but the portfolio manager will consider the event in determining whether the Fund should continue to hold the security.

Illiquid Investments and Restricted Securities

The Fund may invest up to 15% of its net assets in illiquid investments. An illiquid security is any security which the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the security. To the extent required by applicable law and SEC guidance, the Fund will not acquire an illiquid security if such acquisition would cause the aggregate value of illiquid securities to exceed 15% of the Fund’s net assets. If at any time the portfolio manager determines that the value of illiquid securities held by the Fund exceeds 15% of the Fund’s net assets, the portfolio manager will take such steps as it considers appropriate to reduce the percentage as soon as reasonably practicable; the Fund may, however, hold any such investments for a substantial period of time.

Restricted securities are securities subject to legal or contractual restrictions on their resale, such as private placements. Such restrictions might prevent the sale of restricted securities at a time when the sale would otherwise be desirable. Under SEC regulations, certain restricted securities acquired through private placements can be traded freely among qualified purchasers. While restricted securities are generally classified as illiquid, the Fund may determine that a particular

28

Table of Contents

restricted security is “liquid.” Investing in these restricted securities could have the effect of increasing the Fund’s illiquidity if qualified purchasers become, for a time, uninterested in buying these securities.

Restricted securities may be sold only (1) pursuant to SEC Rule 144A or another exemption, (2) in privately negotiated transactions or (3) in public offerings with respect to which a registration statement is in effect under the 1933 Act. Rule 144A securities, although not registered in the U.S., may be sold to qualified institutional buyers in accordance with Rule 144A under the 1933 Act. As noted above, the Fund may determine that some Rule 144A securities are liquid. Where registration is required, the Fund may be obligated to pay all or part of the registration expenses and a considerable period may elapse between the time of the decision to sell and the time the Fund may be permitted to sell a restricted security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the Fund might obtain a less favorable price than prevailed when it decided to sell.

Illiquid securities may be difficult to value, and the Fund may have difficulty disposing of such securities promptly. The Fund does not consider non-U.S. securities to be restricted if they can be freely sold in the principal markets in which they are traded, even if they are not registered for sale in the U.S.

Liquidity Risk Management . In October 2016, the SEC adopted Rule 22e-4 under the 1940 Act requiring, among other things, that the Fund and other Legg Mason open-end funds establish a liquidity risk management program by December 1, 2018 that is reasonably designed to assess and manage liquidity risk. Costs associated with complying with the rule could impact the Fund’s performance and its ability to achieve its investment objective.

Investments in Other Investment Companies

Subject to applicable statutory and regulatory limitations described below, the Fund may invest in shares of other investment companies, including shares of open-end and closed-end investment companies affiliated or unaffiliated with the Fund, business development companies, exchange-traded funds and unregistered investment companies.

An investment in an investment company is subject to the risks associated with that investment company’s portfolio securities. Investments in closed-end funds may entail the additional risk that the market value of such investments may be substantially less than their net asset value. To extent the Fund invests in shares of another investment company, the Fund will indirectly bear a proportionate share of that investment company’s advisory fees and other operating expenses. These fees are in addition to the advisory fees and other operational expenses incurred directly by the Fund. In addition, the Fund could incur a sales charge in connection with purchasing an investment company security or a redemption fee upon the redemption of such security.

Section 12(d)(1)(A) of the 1940 Act provides that a fund may not purchase or otherwise acquire the securities of other “registered investment companies” (as defined in the 1940 Act) if, as a result of such purchase or acquisition, it would own: (i) more than 3% of the total outstanding voting stock of the acquired investment company; (ii) securities issued by any one investment company having a value in excess of 5% of the fund’s total assets; or (iii) securities issued by all investment companies having an aggregate value in excess of 10% of the fund’s total assets. Certain exceptions may be available from these limits such as when the Fund invests in certain exchange-traded funds or money-market funds or in investment companies that are part of the same group of investment companies as the Fund.

Market Sector Risk

To the extent the Fund may be significantly overweight or underweight certain companies, industries or market sectors, the Fund’s performance may be more sensitive to developments affecting those companies, industries or sectors.

Master Limited Partnerships (“MLPs”)

MLPs are limited partnerships or limited liability companies usually taxable as partnerships. MLPs may derive income and gains from, among other things, the exploration, development, mining or production, processing, refining, transportation (including pipelines transporting gas, oil, or products thereof), storage, or the marketing of, or the provision of infrastructure related services relating to, minerals or other natural resources. The value of an investment in some MLPs may be directly affected by the prices of natural resources. The volatility and interrelationships of commodity prices can also indirectly affect certain MLPs due to the potential impact on the volume of commodities transported, processed, stored or distributed. The Fund’s investment in such an MLP may be adversely affected by market perceptions that the performance and distributions or dividends

29

Table of Contents

of MLPs are directly tied to commodity prices. In addition, MLPs are generally considered interest-rate sensitive investments, and during periods of interest rate volatility, may not provide attractive returns.

MLPs generally have two classes of owners, the general partner and limited partners. The general partner is typically owned by a major company (often an energy company), an investment fund, the direct management of the MLP or is an entity owned by one or more of such parties. The general partner may be structured as a private or publicly traded corporation or other entity. The general partner typically controls the operations and management of the MLP through an equity interest of up to 2% in the MLP plus, in many cases, ownership of common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role in the partnership’s operations and management.

MLPs are typically structured such that common units and general partner interests have first priority to receive quarterly cash distributions up to an established minimum amount (“minimum quarterly distributions” or “MQD”). Common and general partner interests also accrue arrearages in distributions to the extent the MQD is not paid. Once common and general partner interests have been paid, subordinated units receive distributions of up to the MQD; however, subordinated units do not accrue arrearages. Distributable cash in excess of the MQD paid to both common and subordinated units is distributed to both common and subordinated units generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner which results in distributions paid per common unit surpassing specified target levels. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions. A common arrangement provides that the general partner can reach a tier where it receives 50% of every incremental dollar paid to common and subordinated unit holders. These incentive distributions encourage the general partner to streamline costs, increase capital expenditures and acquire assets in order to increase the partnership’s cash flow and raise the quarterly cash distribution in order to reach higher tiers. Such results increase costs to the limited partners.

MLP common units represent a limited partnership interest in the MLP. Common units are listed and traded on U.S. securities exchanges, with their value fluctuating predominantly based on prevailing market conditions and the success of the MLP. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability annually to elect directors. In the event of liquidation, common units have preference over subordinated units, but not over debt or preferred units, to the remaining assets of the MLP.

General partner interests of MLPs are typically retained by the original sponsors of an MLP, such as its founders, corporate partners and entities that sell assets to the MLP. The holder of the general partner interest can be liable in certain circumstances for amounts greater than the amount of the holder’s investment in the general partner. General partner interests often confer direct board participation rights in, and in many cases control over the operations of, the MLP. General partner interests can be privately held or owned by publicly traded entities.

Money Market Instruments Generally

Money market instruments are short-term IOUs issued by banks or other non-governmental issuers, the U.S. or non-U.S. governments, or state or local governments. Money market instruments generally have maturity dates of 13 months or less, and may pay interest at fixed, floating or adjustable rates, or may be issued at a discount. Money market instruments may include certificates of deposit, bankers’ acceptances, variable rate demand securities (where the interest rate is reset periodically and the holder may demand payment from the issuer or another obligor at any time), preferred shares, fixed-term obligations, commercial paper (short-term unsecured debt), asset-backed commercial paper, other mortgage-backed and asset-backed securities and repurchase agreements. Asset-backed commercial paper refers to a debt security with an original term to maturity of up to 270 days that may be backed by residential and commercial mortgage loans or mortgage-backed securities or other types of receivables. Payments due on asset-backed commercial paper are supported by cash flows from underlying assets, or one or more liquidity or credit support providers, or both.

Mortgage-Backed and Other Asset-Backed Securities – Generally

An asset-backed security is a fixed income security that derives its value primarily from cash flows relating to a pool of assets. There are a number of different types of asset-backed and related securities, including mortgage-backed securities, securities backed by other pools of collateral (such as automobile loans, student loans, sub-prime mortgages, and credit card receivables), collateralized mortgage obligations, and collateralized debt obligations.

30

Table of Contents

Asset-backed and mortgage-backed securities differ from conventional bonds in that principal is paid over the life of the securities rather than at maturity. As a result, payments of principal of and interest on mortgage-backed securities and asset-backed securities are made more frequently than are payments on conventional debt securities. The average life of asset-backed and mortgage-backed securities is likely to be substantially less than the original maturity of the underlying asset pools as a result of prepayments or foreclosures of mortgages, as applicable. In addition, holders of mortgage-backed securities and of certain asset-backed securities (such as asset-backed securities backed by home equity loans) may receive unscheduled payments of principal at any time representing prepayments on the underlying mortgage loans or financial assets. When the holder of the security attempts to reinvest prepayments or even the scheduled payments of principal and interest, it may receive a rate of interest that is higher or lower than the rate on the mortgage-backed security or asset-backed security originally held. To the extent that mortgage-backed securities or asset-backed securities are purchased by the Fund at a premium, mortgage foreclosures and principal prepayments may result in a loss to the extent of the premium paid. To the extent the loans underlying a security representing an interest in a pool of mortgages or other assets are prepaid, the Fund may experience a loss (if the price at which the respective security was acquired by the Fund was at a premium over par, which represents the price at which the security will be redeemed upon prepayment) or a gain (if the price at which the respective security was acquired by the Fund was at a discount from par). In addition, prepayments of such securities held by the Fund will reduce the share price of the Fund to the extent the market value of the securities at the time of prepayment exceeds their par value, and will increase the share price of the Fund to the extent the par value of the securities exceeds their market value at the time of prepayment. Prepayments may occur with greater frequency in periods of declining interest rates because, among other reasons, it may be possible for borrowers to refinance their outstanding obligation at lower interest rates. When market interest rates increase, the market values of asset-backed and mortgage-backed securities decline. At the same time, however, refinancing slows, which lengthens the effective maturities of these securities. As a result, the negative effect of the rate increase on the market value of asset-backed and mortgage-backed securities is usually more pronounced than it is for other types of fixed income securities.

Changes in the market’s perception of the mortgages or assets backing the security, the creditworthiness of the servicing agent for the loan pool, the originator of the loans, or the financial institution providing any credit enhancement, will all affect the value of an asset-backed or mortgage-backed security, as will the exhaustion of any credit enhancement.

The risks of investing in asset-backed and mortgage-backed securities ultimately depend upon the payment of the underlying loans by the individual borrowers. In its capacity as purchaser of an asset-backed security or mortgage-backed security, the Fund would generally have no recourse to the entity that originated the loans in the event of default by the borrower. The risk of non-payment is greater for asset-backed and mortgage-backed securities that are backed by pools that contain subprime loans, but a level of risk exists for all loans. Market factors adversely affecting loan repayments may include a general economic turndown and high unemployment. Mortgage-backed securities may be adversely affected by a general slowdown in the real estate market, a drop in the market prices of real estate, or an increase in interest rates resulting in higher mortgage payments by holders of adjustable rate mortgages.

Additional information regarding different types of asset-backed and mortgage-backed securities is provided below. Governmental, government-related or private entities may create pools of loan assets offering pass-through investments in addition to those described below. As new types of asset-backed or mortgage-backed securities are developed and offered to investors, the portfolio manager may, consistent with the Fund’s investment objective and policies, consider making investments in such new types of securities.

Mortgage-Backed Securities . Mortgage-backed securities (“MBS”) represent interests in pools of mortgage loans made by lenders such as savings and loan institutions, mortgage bankers, commercial banks and others, to finance purchases of homes, commercial buildings or other real estate. The individual mortgage loans are assembled for sale to investors (such as the Fund) by various governmental or government-related agencies and private organizations, such as dealers.

Government-sponsored MBS . Some government sponsored mortgage-related securities are backed by the full faith and credit of the United States. The Government National Mortgage Association (“Ginnie Mae”), the principal guarantor of such securities, is a wholly owned United States government corporation within the Department of Housing and Urban Development. Other government-sponsored mortgage-related securities are not backed by the full faith and credit of the United States government. Issuers of such securities include Fannie Mae (formally known as the Federal National Mortgage Association) and Freddie Mac (formally known as the Federal Home Loan Mortgage Corporation). Fannie Mae is a government-sponsored corporation which is subject to general regulation by the Secretary of Housing and Urban Development. Pass-through securities

issued by Fannie Mae are guaranteed as to timely payment of principal and interest by Fannie Mae. Freddie Mac is a stockholder-owned corporation chartered by Congress and subject to general regulation by the Department of Housing and Urban Development. Participation certificates representing interests in mortgages from Freddie Mac’s national portfolio are guaranteed as to the timely payment of interest and ultimate collection of principal by Freddie Mac. The U.S. government has provided financial support to Fannie Mae and Freddie Mac in the past, but there can be no assurances that it will support these or other government-sponsored entities in the future.

Privately Issued MBS . Unlike MBS issued or guaranteed by the U.S. government or certain government-sponsored entities, MBS issued by private issuers do not have a government or government-sponsored entity guarantee, but may have credit enhancement provided by external entities such as banks or financial institutions or achieved through the structuring of the transaction itself.

In addition, MBS that are issued by private issuers are not subject to the underwriting requirements for the underlying mortgages that are applicable to those MBS that have a government or government-sponsored entity guarantee. As a result, the mortgage loans underlying private MBS may, and frequently do, have less favorable collateral, credit risk or other underwriting characteristics than government or government-sponsored MBS and have wider variances in a number of terms including interest rate, term, size, purpose 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 MBS 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.

Privately issued mortgage-backed securities are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-backed securities held in the Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loans.

Adjustable rate mortgage-backed securities . Adjustable rate mortgage-backed securities (“ARMBS”) are pass-through securities collateralized by mortgages with adjustable rather than fixed rates. Adjustable rate mortgages eligible for inclusion in a mortgage pool generally provide for a fixed initial mortgage interest rate for a set number of scheduled monthly payments. After that schedule of payments has been completed, the interest rates of the adjustable rate mortgages are subject to periodic adjustment based on changes to a designated benchmark index.

Mortgages underlying most ARMBS may contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the mortgage. In addition, certain adjustable rate mortgages provide for additional limitations on the maximum amount by which the mortgage interest rate may adjust for any single adjustment period. In the event that market rates of interest rise more rapidly to levels above that of the maximum rate for the adjustable rate mortgages underlying an ARMBS, the ARMBS’ coupon may represent a below market rate of interest. In these circumstances, the market value of the ARMBS will likely have fallen. During periods of declining interest rates, income to the Fund derived from adjustable rate mortgages that remain in the mortgage pool underlying the ARMBS may decrease in contrast to the income on fixed rate mortgages, which will remain constant. Adjustable rate mortgages also have less potential for appreciation in value as interest rates decline than do fixed rate investments. In addition, the current yields on ARMBS may be different than market yields during interim periods between coupon reset dates.

Stripped mortgage-backed securities . Stripped mortgage-backed securities (“SMBS”) are structured with two or more classes of securities that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have at least one class receiving only a small portion of the principal. In the most extreme case, one class will receive all of the interest (“IO” or interest-only class), while the other class will receive all of the principal (“PO” or principal-only class). The yield to maturity on IOs, POs and other mortgage-backed securities that are purchased at a substantial premium or discount generally are extremely sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on such securities’ yield to maturity. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the Fund may fail to fully recoup its initial investment in these securities even if the securities have received the highest rating by a NRSRO.

SMBS have greater volatility than other types of securities. Although SMBS are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, the market for such securities has not yet been fully developed. Accordingly, the secondary market for SMBS may be more volatile and less liquid than that for other MBS, potentially limiting the Fund’s ability to buy or sell SMBS at any particular time.

Collateralized mortgage obligations . Another type of security representing an interest in a pool of mortgage loans is known as a collateralized mortgage obligation (“CMO”). CMOs represent interests in a short-term, intermediate-term or long-term portion of a mortgage pool. Each portion of the pool receives monthly interest payments, but the principal repayments pass through to the short-term CMO first and to the long-term CMO last. A CMO permits an investor to more accurately predict the rate of principal repayments. CMOs are issued by private issuers, such as broker-dealers, and by government agencies, such as Fannie Mae and Freddie Mac. Investments in CMOs are subject to the same risks as direct investments in the underlying mortgage-backed securities. In addition, in the event of a bankruptcy or other default of a broker that issued the CMO held by the Fund, the Fund could experience delays in liquidating both its position and losses. The Fund may invest in CMOs in any rating category of the recognized rating services and may invest in unrated CMOs. The Fund may also invest in “stripped” CMOs, which represent only the income portion or the principal portion of the CMO. The values of stripped CMOs are very sensitive to interest rate changes; accordingly, these instruments present a greater risk of loss than conventional mortgage-backed securities.

Tiered index bonds . Tiered index bonds are relatively new forms of mortgage-related securities. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined “strike” rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the “strike” rate, the interest rate of the tiered index bond will decrease. Thus, under these circumstances, the interest rate on a tiered index bond, like an inverse floater, will move in the opposite direction of prevailing interest rates, with the result that the price of the tiered index bond would decline and may be considerably more volatile than that of a fixed-rate bond.
