DESCRIPTION OF THE FUND AND ITS INVESTMENTS AND RISKS

The Fund’s Prospectus contains information about the investment objective and policies of the Fund. This SAI should only be read in conjunction with the Prospectus of the Fund.

In addition to the principal investment strategies and the principal risks of the Fund described in the Fund’s Prospectus, the Fund may employ other investment practices and may be subject to additional risks, which are described below.

The Target Retirement 2065 Fund seeks to achieve its investment objective by investing in a combination of domestic and international mutual funds and exchange-traded funds sponsored by SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”) or its affiliates (“Underlying Funds”) using an asset allocation strategy. In managing their portfolios of investments, the Underlying Funds may purchase various securities and investment related instruments and make use of various investment techniques, including, but not limited to, those described below. Except as otherwise stated, references in this section to “the Funds,” “each Fund,” or “a Fund” may, as applicable, refer to the Fund, one or more Underlying Funds, or more than one of the foregoing.

ADDITIONAL INVESTMENTS AND RISKS

To the extent consistent with its investment objective and restrictions, the Fund may invest in the following instruments and use the following techniques, and is subject to the following additional risks.

Bonds

The Fund may invest a portion of its assets in bonds. A bond is an interest-bearing security issued by a company, governmental unit or, in some cases, a non-U.S. entity. The issuer of a bond has a contractual obligation to pay interest at a stated rate on specific dates and to repay principal (the bond’s face value) periodically or on a specified maturity date; provided, however, a zero coupon bond pays no interest to its holder during its life. The value of a zero coupon bond to the Fund consists of the difference between such bond’s face value at the time of maturity and the price for which it was acquired, which may be an amount significantly less than its face value (sometimes referred to as a “deep discount” price).

An issuer may have the right to redeem or “call” a bond before maturity, in which case the investor may have to reinvest the proceeds at lower market rates. Most bonds bear interest income at a “coupon” rate that is fixed for the life of the bond. The value of a fixed rate bond usually rises when market interest rates fall, and falls when market interest rates rise. Accordingly, a fixed rate bond’s yield (income as a percent of the bond’s current value) may differ from its coupon rate as its value rises or falls. Fixed rate bonds generally are also subject to inflation risk, which is the risk that the value of the bond or income from the bond will be worth less in the future as inflation decreases the value of money. This could mean that, as inflation increases, the “real” value of the assets of a fund holding fixed rate bonds can decline, as can the value of the fund’s distributions. Other types of bonds bear income at an interest rate that is adjusted periodically. Because of their adjustable interest rates, the value of “floating-rate” or “variable-rate” bonds fluctuates much less in response to market interest rate movements than the value of fixed rate bonds. The Fund may treat some of these bonds as having a shorter maturity for purposes of calculating the weighted average maturity of its investment portfolio. Bonds may be senior or subordinated obligations. Senior obligations generally have the first claim on a corporation’s earnings and assets and, in the event of liquidation, are paid before subordinated obligations. Bonds may be unsecured (backed only by the issuer’s general creditworthiness) or secured (also backed by specified collateral). The investment return of corporate bonds reflects interest on the bond and changes in the market value of the bond. The market value of a corporate bond may be affected by the credit rating of the corporation, the corporation’s performance and perceptions of the corporation in the market place. There is a risk that the issuers of the securities may not be able to meet their obligations on interest or principal payments at the time called for by such a security.

Cash Reserves

The Fund may hold portions of its assets in cash or short-term debt instruments with remaining maturities of 397 days or less pending investment or to meet anticipated redemptions and day-to-day operating expenses. Short-term debt instruments consist of: (i) short-term obligations of the U.S. Government, its agencies, instrumentalities, authorities or political subdivisions; (ii) other short-term debt securities rated at the time of purchase Aa or higher by Moody’s Investors Service, Inc. (“Moody’s”) or AA or higher by S&P Global Ratings (“S&P) or, if unrated, of comparable quality in the opinion of SSGA FM; (iii) commercial paper; (iv) bank obligations, including negotiable certificates of deposit, time deposits and bankers’ acceptances; and (v) repurchase agreements.

Cleared Derivatives Transactions

Under recently adopted rules and regulations, transactions in some types of swaps are required to be centrally cleared. In a cleared derivatives transaction, the Fund’s counterparty to the transaction is a central derivatives clearing organization, or clearing house, rather than a bank or broker. Because the Fund is not a member of a clearing house, and only members of a clearing house can

Table of Contents

participate directly in the clearing house, the Fund holds cleared derivatives through accounts at clearing members. In cleared derivatives transactions, the Fund will make payments (including margin payments) to and receive payments from a clearing house through its accounts at clearing members. Clearing members guarantee performance of their clients’ obligations to the clearing house. Centrally cleared derivative arrangements may be less favorable to the Fund than bilateral (non-cleared) arrangements. For example, the Fund may be required to provide greater amounts of margin for cleared derivatives transactions than for bilateral derivatives transactions. Also, in contrast to bilateral derivatives transactions, in some cases following a period of notice to the Fund, a clearing member generally can require termination of existing cleared derivatives transactions at any time or an increase 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. The Fund is subject to risk if it enters into a derivatives transaction that is required to be cleared (or which the Adviser expects to be cleared), and no clearing member is willing or able to clear the transaction on the Fund’s behalf. In that case, 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 loss of hedging protection. In addition, the documentation governing the relationship between the Fund and clearing members is drafted by the clearing members and generally is less favorable to the Fund than typical bilateral derivatives documentation. For example, documentation relating to cleared derivatives generally includes a one-way indemnity by the Fund in favor of the clearing member for losses the clearing member incurs as the Fund’s clearing member. Also, such documentation typically does not provide the Fund any remedies if the clearing member defaults or becomes insolvent.

Counterparty risk with respect to derivatives has been and will continue to be affected by new rules and regulations relating to the derivatives market. With respect to a centrally cleared transaction, a party is subject to the credit risk of the clearing house and the clearing member through which it holds its cleared position. Credit risk of market participants with respect to centrally cleared derivatives 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 regulation to segregate all funds received from customers with respect to cleared derivatives positions from the clearing member’s proprietary assets. However, all funds and other property received by a clearing member from its customers with respect to cleared derivatives are generally held by the clearing member on a commingled basis in an omnibus account (which can be invested in instruments permitted under the regulations). Therefore, 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 the funds held by the clearing member on behalf of customers, with a claim against the clearing member for any deficiency. Also, the clearing member is required to transfer to the clearing house the amount of margin required by the clearing house for cleared derivatives, which amount is generally held in an omnibus account at the clearing house for all customers of the clearing member. Regulations promulgated by the Commodity Futures Trading Commission (the “CFTC”) require that the clearing member notify the clearing house of the initial margin provided by the clearing member to the clearing house that is attributable to each customer. However, if the clearing member does not accurately report the Fund’s initial margin, the Fund is subject to the risk that a clearing house will use the assets attributable to it in the clearing house’s omnibus account to satisfy payment obligations a defaulting customer of the clearing member has to the clearing house. In addition, clearing members generally provide the clearing house the net amount of variation margin required for cleared swaps for all of its customers, rather than individually for each customer. The Fund is therefore subject to the risk that a clearing house 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 positions 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 have only an unsecured creditor claim in an insolvency of the clearing member with respect to the margin held by the clearing member.

Swap Execution Facilities

Certain derivatives contracts are required to be executed through swap execution facilities (“SEFs”). A SEF is a trading platform where multiple market participants can execute derivatives by accepting bids and offers made by multiple other participants in the platform. Such requirements may make it more difficult and costly for investment funds, such as the Fund, to enter into highly tailored or customized transactions. Trading swaps on a SEF may offer certain advantages over traditional bilateral over-the-counter trading, such as ease of execution, price transparency, increased liquidity and/or favorable pricing. Execution through a SEF is not, however, without additional costs and risks, as parties are required to comply with SEF and CFTC rules and regulations, including disclosure and recordkeeping obligations, and SEF rights of inspection, among others. SEFs typically charge fees, and if the Fund executes derivatives on a swap execution facility through a broker intermediary, the intermediary may impose fees as well. The Fund also may be required to indemnify a SEF, or a broker intermediary who executes 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. In addition, the Fund may be subject to execution risk if it enters into a derivatives transaction that is required to be cleared, and no clearing member is willing to clear the transaction on the Fund’s behalf. In that case, the transaction might have to be terminated, and the Fund could lose some or all of the benefit of any increase in the value of the transaction after the time of the trade.

Risks Associated with Derivatives Regulation

The U.S. government has enacted legislation that provides for new regulation of the derivatives market, including clearing, margin, reporting, and registration requirements. The European Union (the “EU”) and some other countries are implementing similar requirements, which will affect the Fund when it enters into a derivatives transaction with a counterparty organized in that country or otherwise subject to that country’s derivatives regulations. Clearing rules and other new rules and regulations could, among other things, restrict the Fund’s ability to engage in, or increase the cost to the Fund of, derivatives transactions, for example, by making some types of derivatives no longer available to the Fund, increasing margin or capital requirements, or otherwise limiting liquidity or increasing transaction costs. 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, as noted above, central clearing and related requirements expose the Fund to new kinds of costs and risks.

For example, 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 new special resolution regimes adopted in the United States, the EU 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 EU, 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”).

Additionally, U.S. regulators, the EU and certain other jurisdictions have adopted minimum margin and capital requirements for uncleared derivatives transactions. It is expected that these regulations will have a material impact on the Fund’s use of uncleared derivatives. These rules impose minimum margin requirements on derivatives transactions between the Fund and its counterparties and may increase the amount of margin the Fund is required to provide. They impose regulatory requirements on the timing of transferring margin and the types of collateral that parties are permitted to exchange.

These and other regulations are new and evolving, so their potential impact on the Fund and the financial system are not yet known.

Commodities

General. The Fund may invest in commodities. There are several additional risks associated with transactions in commodity futures contracts, swaps on commodity futures contracts, commodity forward contracts and other commodities instruments. In the commodity instruments markets, producers of the underlying commodity may decide to hedge the price risk of selling the commodity by selling commodity instruments today to lock in the price of the commodity at delivery tomorrow. In order to induce speculators to purchase the other side of the same commodity instrument, the commodity producer generally must sell the commodity instrument at a lower price than the expected future spot price. Conversely, if most hedgers in the commodity instruments market are purchasing commodity instruments to hedge against a rise in prices, then speculators will only sell the other side of the commodity instrument at a higher future price than the expected future spot price of the commodity. The changing nature of the hedgers and speculators in the commodity markets will influence whether futures prices are above or below the expected future spot price, which can have significant implications for the Fund. If the nature of hedgers and speculators in commodity instruments markets has shifted when it is time for the Fund to reinvest the proceeds of a maturing contract in a new commodity instrument, the Fund might reinvest at a higher or lower future price, or choose to pursue other investments. The commodities which underlie commodity instruments may be subject to additional economic and non-economic variables, such as drought, floods, weather, livestock disease, embargoes, tariffs, and international economic, political and regulatory developments. These factors may have a larger impact on commodity prices and commodity-linked instruments than on traditional securities. Certain commodities are also subject to limited pricing flexibility because of supply and demand factors. Others are subject to broad price fluctuations as a result of the volatility of the prices for certain raw materials and the instability of supplies of other materials. These additional variables may create additional investment risks which subject the Fund’s investments to greater volatility than other investments. Also, unlike the financial instruments markets, in the commodity instruments markets there are costs of physical storage associated with purchasing the underlying commodity. The price of the commodity instruments contract will reflect the storage costs of purchasing the physical commodity, including the time value of money invested in the physical commodity. To the extent that the storage costs for an underlying commodity change while the Fund is invested in instruments on that commodity, the value of the commodity instrument may change proportionately.

The Fund’s ability to invest in commodity-linked investments may be limited by the Fund’s intention to qualify as a regulated investment company (“RIC”) under the Internal Revenue Code of 1986, as amended (the “Code”) and could bear on the ability of the Fund to so qualify. See “Taxation of the Fund” below.

Commodity-Linked Investments. The Fund may invest in commodity-linked investments. The Fund may seek to provide exposure to the investment returns of real assets that trade in the commodity markets through commodity-linked derivative securities, such as structured notes, discussed below, which are designed to provide this exposure without direct investment in physical commodities or

6

Table of Contents

commodities futures contracts. Real assets are assets such as oil, gas, industrial and precious metals, livestock, and agricultural or meat products, or other items that have tangible properties, as compared to stocks or bonds, which are financial instruments. In choosing investments, the Adviser seeks to provide exposure to various commodities and commodity sectors. The value of commodity-linked derivative securities held by the Fund may be affected by a variety of factors, including, but not limited to, overall market movements and other factors affecting the value of particular industries or commodities, such as weather, disease, embargoes, acts of war or terrorism, or political and regulatory developments.

The prices of commodity-linked derivative securities may move in different directions than investments in traditional equity and debt securities when the value of those traditional securities is declining due to adverse economic conditions. As an example, during periods of rising inflation, debt securities have historically tended to decline in value due to the general increase in prevailing interest rates. Conversely, during those same periods of rising inflation, the prices of certain commodities, such as oil and metals, have historically tended to increase. Of course, there cannot be any guarantee that these investments will perform in that manner in the future, and at certain times the price movements of commodity-linked instruments have been parallel to those of debt and equity securities. Commodities have historically tended to increase and decrease in value during different parts of the business cycle than financial assets. Nevertheless, at various times, commodities prices may move in tandem with the prices of financial assets and thus may not provide overall portfolio diversification benefits. Under favorable economic conditions, the Fund’s investments may be expected to underperform an investment in traditional securities. Over the long term, the returns on the Fund’s investments are expected to exhibit low or negative correlation with stocks and bonds.

Because commodity-linked investments are available from a relatively small number of issuers, the Fund’s investments will be particularly subject to counterparty risk, which is the risk that the issuer of the commodity-linked derivative (which issuer may also serve as counterparty to a substantial number of the Fund’s commodity-linked and other derivative investments) will not fulfill its contractual obligations.

The Fund’s ability to invest in commodity-linked investments may be limited by the Fund’s intention to qualify as a RIC and could bear on the ability of the Fund to so qualify. See “Taxation of the Fund” below.

Credit Default Swaps and Total Return Swaps

The Fund may enter into credit default swaps or total return swaps to gain market exposure, manage liquidity, increase total returns or for hedging purposes. Credit default swaps and total return swaps are typically governed by the standard terms and conditions of an ISDA Master Agreement.

A credit default swap involves a protection buyer and a protection seller. The Fund may be either a protection buyer or seller. The protection buyer in a credit default swap makes periodic premium payments to the protection seller during the swap term in exchange for the protection seller agreeing to make certain defined payments to the protection buyer in the event certain defined credit events occur with respect to a particular security, issuer or basket of securities. A total return swap involves a total return receiver and a total return payor. The Fund may either be a total return receiver or payor. Generally, the total return payor sells to the total return receiver an amount equal to all cash flows and price appreciation on a defined security or asset payable at periodic times during the swap term (i.e., credit risk) in return for a periodic payment from the total return receiver based on a designated interest rate (e.g., the London Interbank Offered Rate (“LIBOR”)) and spread plus the amount of any price depreciation on the reference security or asset. The total return payor does not need to own the underlying security or asset to enter into a total return swap. The final payment at the end of the swap term includes final settlement of the current market price of the underlying reference security or asset, and payment by the applicable party for any appreciation or depreciation in value. Usually, collateral must be posted by the total return receiver to secure the periodic interest-based and market price depreciation payments depending on the credit quality of the underlying reference security and creditworthiness of the total return receiver, and the collateral amount is marked-to-market daily equal to the market price of the underlying reference security or asset between periodic payment dates.

In both credit default swaps and total return swaps, the same general risks inherent to derivative transactions are present; however, the use of credit default swaps and total return swaps can involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, credit default swaps and total return swaps are subject to counterparty credit risk, leverage risk, hedging risk, correlation risk and liquidity risk. The Fund will enter into credit default swap or a total return swap only with counterparties that the Adviser determines to meet certain standards of creditworthiness. In a credit default swap, a buyer generally also will lose its premium and recover nothing should no credit event occur and the swap is held to its termination date. If a credit event were to occur, the value of any deliverable obligation received by the seller, coupled with the upfront or periodic payments previously received, may be less than the full notional value it pays to the buyer, resulting in a loss of value to the seller. The Fund’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owing to the Fund).

Table of Contents

Swaps are highly specialized instruments that require investment techniques, risk analyses, and tax planning different from those associated with the ownership of stocks, bonds, and other traditional investments. The use of a swap agreement requires an understanding not only of the referenced obligation, reference rate, or index, but also of the swap agreement itself. Because some swap agreements have a leverage component, adverse changes in the value or level of the underlying asset, reference rate, or index can result in a loss substantially greater than the amount invested in the swap itself. Certain swaps have the potential for unlimited loss, regardless of the size of the initial investment.

When effecting such transactions, cash or other liquid assets held by the Fund of a dollar amount sufficient to meet the Fund’s obligations under the swap agreement will be segregated on the Fund’s records at the trade date and maintained until the transaction is settled. Such segregated assets will be marked to market on a daily basis, and if the market value of such assets declines, additional cash or other assets will be segregated so that the market value of the segregated assets will equal the amount of the Fund’s obligations under the swap agreement.

The Fund’s exposure under a credit default swap may be considered leverage and as such be subject to the restrictions on leveraged derivatives.

Custodial Risk

There are risks involved in dealing with the custodians or brokers who hold the Fund’s investments or settle the Fund’s trades. It is possible that, in the event of the insolvency or bankruptcy of a custodian or broker, the Fund would be delayed or prevented from recovering its assets from the custodian or broker, or its estate, and may have only a general unsecured claim against the custodian or broker for those assets. In recent insolvencies of brokers or other financial institutions, the ability of certain customers to recover their assets from the insolvent’s estate has been delayed, limited, or prevented, often unpredictably, and there is no assurance that any assets held by the Fund with a custodian or broker will be readily recoverable by the Fund. In addition, there may be limited recourse against non-U.S. sub-custodians in those situations in which the Fund invests in markets where custodial and/or settlement systems and regulations are not fully developed, including emerging markets, and the assets of the Fund have been entrusted to such sub-custodians. SSGA FM or an affiliate may serve as the custodian of the Fund.

Eurodollar Certificates of Deposit (“ECDs”), Eurodollar Time Deposits (“ETDs”) and Yankee Certificates of Deposit (“YCDs”)

The Fund may invest in ECDs, ETDs and YCDs. ECDs and ETDs are U.S. dollar denominated certificates of deposit and time deposits, respectively, issued by non-U.S. branches of domestic banks and non-U.S. banks. YCDs are U.S. dollar denominated certificates of deposit issued by U.S. branches of non-U.S. banks.

Different risks than those associated with the obligations of domestic banks may exist for ECDs, ETDs and YCDs because the banks issuing these instruments, or their domestic or non-U.S. branches, are not necessarily subject to the same regulatory requirements that apply to domestic banks, such as loan limitations, examinations and reserve, accounting, auditing, recordkeeping and public reporting requirements. Obligations of non-U.S. issuers also involve risks such as future unfavorable political and economic developments, withholding or other taxes, seizures of non-U.S. deposits, currency controls, interest limitations, and other governmental restrictions that might affect repayment of principal or payment of interest, or the ability to honor a credit commitment.

Foreign Currency Transactions and Foreign Currency Derivatives

The Fund may enter into a variety of different foreign currency transactions, including, by way of example, currency forward transactions, spot transactions, futures and forward contracts, swaps, or options. Most of these transactions are entered into “over the counter,” and the Fund assumes the risk that the counterparty may be unable or unwilling to perform its obligations, in addition to the risk of unfavorable or unanticipated changes in the values of the currencies underlying the transactions. Certain types of over-the-counter currency transactions may be uncollateralized, and the Fund may not be able to recover all or any of the assets owed to it under such transactions if its counterparty should default. In some markets or in respect of certain currencies, the Fund may be required, or agree, in SSGA FM’s discretion, to enter into foreign currency transactions via the custodian’s relevant sub-custodian. SSGA FM may be subject to a conflict of interest in agreeing to any such arrangements on behalf of the Fund. Such transactions executed directly with the sub-custodian are executed at a rate determined solely by such sub-custodian. Accordingly, the Fund may not receive the best pricing of such currency transactions. Regulatory changes in a number of jurisdictions may require that certain currency transactions be subject to central clearing, or be subject to new or increased collateral requirements. These changes could increase the costs of currency transactions to the Fund and may make certain transactions unavailable; they may also increase the credit risk of such transactions to the Fund.

Foreign Securities

The Fund is permitted to invest in foreign securities. Foreign securities include securities of foreign companies and foreign governments (or agencies or subdivisions thereof). If the Fund’s securities are held abroad, the countries in which such securities may be held and the sub-custodian holding them must be approved by the Board of Trustees of the Trust (the “Board of Trustees” or the “Board”) or its delegate under applicable rules adopted by the Securities and Exchange Commission (“SEC”). In buying foreign securities, the Fund may convert U.S. dollars into foreign currency, but only to effect securities transactions on foreign securities exchanges and not to hold such currency as an investment.

The globalization and integration of the world economic system and related financial markets have made it increasingly difficult to define issuers geographically. Accordingly, the Fund intends to construe geographic terms such as “foreign,” “non-U.S.” “European,” “Latin American,” and “Asian,” in the manner that affords to the Fund the greatest flexibility in seeking to achieve its investment objective(s). Specifically, in circumstances where the investment objective and/or strategy is to invest at least some percentage of the Fund’s assets in foreign securities, etc., the Fund will take the view that a security meets this description so long as the issuer of a security is tied economically to the particular country or geographic region indicated by words of the relevant investment objective and/or strategy (the “Relevant Language”). For these purposes the issuer of a security is deemed to have that tie if:

In addition, the Fund intends to treat derivative securities (e.g., call options) by reference to the underlying security. Conversely, if the investment objective and/or strategy of the Fund limits the percentage of assets that may be invested in “foreign securities,” etc. or prohibits such investments altogether, the Fund intends to categorize securities as “foreign,” etc. only if the security possesses all of the attributes described above in clauses (i), (ii) and (iii).

Investments in foreign securities involve special risks and considerations. As foreign companies are not generally subject to uniform accounting, auditing and financial reporting standards, practices and requirements comparable to those applicable to domestic companies, there may be less publicly available information about a foreign company than about a domestic company. For example, foreign markets have different clearance and settlement procedures. Delays in settlement could result in temporary periods when assets of the Fund are uninvested. The inability of the Fund to make intended security purchases due to settlement problems could cause it to miss certain investment opportunities. They may also entail certain other risks, such as the possibility of one or more of the following: imposition of dividend or interest withholding or other taxes (in each case, which taxes could potentially be confiscatory), higher brokerage costs, thinner trading markets, currency blockages or transfer restrictions, expropriation, nationalization, military coups or other adverse political or economic developments; less government supervision and regulation of securities exchanges, brokers and listed companies; and the difficulty of enforcing obligations in other countries. Purchases of foreign securities are usually made in foreign currencies and, as a result, the Fund may incur currency conversion costs and may be affected favorably or unfavorably by changes in the value of foreign currencies against the U.S. dollar. Further, it may be more difficult for the Fund’s agents to keep currently informed about corporate actions which may affect the prices of portfolio securities. Communications between the United States and foreign countries may be less reliable than within the United States, thus increasing the risk of delayed settlements of portfolio transactions or loss of certificates for portfolio securities. Certain markets may require payment for securities before delivery. The Fund’s ability and decisions to purchase and sell portfolio securities may be affected by laws or regulations relating to the convertibility of currencies and repatriation of assets.

A number of current significant political, demographic and economic developments may affect investments in foreign securities and in securities of companies with operations overseas. Such developments include dramatic political changes in government and economic policies in several Eastern European countries and the republics composing the former Soviet Union, as well as the unification of the European Economic Community. The course of any one or more of these events and the effect on trade barriers, competition and markets for consumer goods and services are uncertain. Similar considerations are of concern with respect to developing countries. For example, the possibility of revolution and the dependence on foreign economic assistance may be greater in these countries than in developed countries. Management seeks to mitigate the risks associated with these considerations through diversification and active professional management.

Forward Commitments

The Fund may invest in forward commitments. The Fund may contract to purchase securities for a fixed price at a future date beyond customary settlement time consistent with the Fund’s ability to manage its investment portfolio and meet redemption requests. The Fund may dispose of a commitment prior to settlement if it is appropriate to do so and realize short-term profits or losses upon such sale. When effecting such transactions, cash or other liquid assets (such as liquid high quality debt obligations) held by the Fund of a dollar amount sufficient to make payment for the portfolio securities to be purchased will be segregated on the Fund’s records at the trade date and maintained until the transaction is settled. Such segregated assets will be marked to market on a daily basis, and if the market value of such assets declines, additional cash or assets will be segregated so that the market value of the segregated assets will equal the amount of the Fund’s obligations. Forward commitments involve a risk of loss if the value of the security to be purchased declines prior to the settlement date, or if the other party fails to complete the transaction.

Futures Contracts and Options on Futures

The Fund may enter into futures contracts on securities in which it may invest or on indices comprised of such securities and may purchase and write call and put options on such contracts.

Futures contracts. A financial futures contract is a contract to buy or sell a specified quantity of financial instruments such as U.S. Treasury bills, notes and bonds at a specified future date at a price agreed upon when the contract is made. An index futures contract is a contract to buy or sell specified units of an index at a specified future date at a price agreed upon when the contract is made. The value of a unit is based on the current value of the index. Under such contracts no delivery of the actual securities making up the index takes place. Rather, upon expiration of the contract, settlement is made by exchanging cash in an amount equal to the difference between the contract price and the closing price of the index at expiration, net of variation margin previously paid. Futures contracts are traded in the United States only on commodity exchanges or boards of trade — known as “contract markets” — approved for such trading by the CFTC, and must be executed through a futures commission merchant or brokerage firm which is a member of the relevant contract market.

Although many futures contracts by their terms call for actual delivery or acceptance of commodities or securities, in most cases the contracts are closed out before the settlement date without the making or taking of delivery, but rather by entering into an offsetting contract (a “closing transaction”). Upon entering into a futures contract, the Fund is required to deposit initial margin with the futures broker. The initial margin serves as a “good faith” deposit that the Fund will honor its potential future commitments. Subsequent payments (called “variation margin” or “maintenance margin”) to and from the broker are made on a daily basis as the price of the underlying security or commodity fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking to the market.” If the Fund is unable to enter into a closing transaction, the amount of the Fund’s potential loss may be unlimited. Futures contracts also involve brokerage costs.

The Fund will not commit more than 5% of the market value of its total assets to initial margin deposits on futures and premiums paid for options on futures.

Registration under the Commodity Exchange Act. The Fund is operated by persons who have claimed an exclusion from the definition of the term “commodity pool operator” with respect to the Fund, under the Commodity Exchange Act (the “CEA”), and therefore, are not subject to registration or regulation as a commodity pool operator under the CEA. As a result, the Fund is limited in its ability to trade instruments subject to the CFTC’s jurisdiction, including commodity futures (which include futures on broad-based securities indexes, interest rate futures and currency futures), options on commodity futures, certain swaps or other investments (whether directly or indirectly through investments in other investment vehicles).

Under this exclusion, the Fund must satisfy one of the following two trading limitations whenever it enters into a new commodity trading position: (1) the aggregate initial margin and premiums required to establish the Fund’s positions in CFTC-regulated instruments may not exceed 5% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such investments); or (2) the aggregate net notional value of such instruments, determined at the time the most recent position was established, may not exceed 100% of the liquidation value of the Fund’s portfolio (after accounting for unrealized profits and unrealized losses on any such positions). The Fund would not be required to consider its exposure to such instruments if they were held for “bona fide hedging” purposes, as such term is defined in the rules of the CFTC. In addition to meeting one of the foregoing trading limitations, the Fund may not market itself as a commodity pool or otherwise as a vehicle for trading in the markets for CFTC-regulated instruments.

Options on futures contracts. In return for the premium paid, options on futures contracts give the purchaser the right to assume a position in a futures contract at the specified option exercise price at any time during the period of the option. Options on futures are similar to options on securities except that options on futures give the purchaser the right, in return for the premium paid, to assume a position in a futures contract (a long position if the option is a call and a short position if the option is a put) at a specified exercise price at any time during the period of the option. Upon exercise of the option, the delivery of the futures position by the writer of the option to the holder of the option will be accompanied by delivery of the accumulated balance in the writer’s futures margin account which represents the amount by which the market price of the futures contract, at exercise, exceeds (in the case of a call) or is less than

10

(in the case of a put) the exercise price of the option on the futures. If an option is exercised on the last trading day prior to its expiration date, the settlement will be made entirely in cash. Purchasers of options who fail to exercise their options prior to the exercise date suffer a loss of the premium paid.

As with options on securities, the holder or writer of an option may terminate his position by selling or purchasing an offsetting option. There is no guarantee that such closing transactions can be effected.

The Fund will be required to deposit initial margin and maintenance margin with respect to put and call options on futures contracts written by it pursuant to brokers’ requirements similar to those described above in connection with the discussion of futures contracts.

Risks of transactions in futures contracts and related options. Successful use of futures contracts by the Fund is subject to the Adviser’s ability to predict movements in various factors affecting financial markets. Compared to the purchase or sale of futures contracts, the purchase of call or put options on futures contracts involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options (plus transaction costs). However, there may be circumstances when the purchase of a call or put option on a futures contract would result in a loss to the Fund when the purchase or sale of a futures contract would not, such as when there is no movement in the prices of the hedged investments. The writing of an option on a futures contract involves risks similar to those risks relating to the sale of futures contracts.

The use of options and futures strategies involves the risk of imperfect correlation among movements in the prices of the securities underlying the futures and options purchased and sold by the Fund, of the options and futures contracts themselves, and, in the case of hedging transactions, of the securities which are the subject of a hedge. The successful use of these strategies further depends on the ability of the Adviser to forecast interest rates and market movements correctly.

There is no assurance that higher than anticipated trading activity or other unforeseen events might not, at times, render certain market clearing facilities inadequate, and thereby result in the institution by exchanges of special procedures which may interfere with the timely execution of customer orders.

To reduce or eliminate a position held by the Fund, the Fund may seek to close out such a position. The ability to establish and close out positions will be subject to the development and maintenance of a liquid secondary market. It is not certain that this market will develop or continue to exist for a particular futures contract or option. Reasons for the absence of a liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain contracts or options; (ii) restrictions may be imposed by an exchange on opening transactions or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of contracts or options, or underlying securities; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or a clearing corporation may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of contracts or options (or a particular class or series of contracts or options), in which event the secondary market on that exchange for such contracts or options (or in the class or series of contracts or options) would cease to exist, although outstanding contracts or options on the exchange that had been issued by a clearing corporation as a result of trades on that exchange would likely continue to be exercisable in accordance with their terms.

U.S. Treasury security futures contracts and options. Some U.S. Treasury security futures contracts require the seller to deliver, or the purchaser to take delivery of, the type of U.S. Treasury security called for in the contract at a specified date and price; others may be settled in cash. Options on U.S. Treasury security futures contracts give the purchaser the right in return for the premium paid to assume a position in a U.S. Treasury security futures contract at the specified option exercise price at any time during the period of the option.

Successful use of U.S. Treasury security futures contracts by the Fund is subject to the Adviser’s ability to predict movements in the direction of interest rates and other factors affecting markets for debt securities. For example, if the Fund has sold U.S. Treasury security futures contracts in order to hedge against the possibility of an increase in interest rates which would adversely affect the values of securities held in its portfolio, and the prices of the Fund’s securities increase instead as a result of a decline in interest rates, the Fund will lose part or all of the benefit of the increased value of its securities which it has hedged because it will have offsetting losses in its futures positions. In addition, in such situations, if the Fund has insufficient cash, it may have to sell securities to meet daily maintenance margin requirements at a time when it may be disadvantageous to do so.

There is also a risk that price movements in U.S. Treasury security futures contracts and related options will not correlate closely with price movements in markets for particular securities. For example, if the Fund has hedged against a decline in the values of tax-exempt securities held by it by selling Treasury security futures and the values of Treasury securities subsequently increase while the values of the Fund’s tax-exempt securities decrease, the Fund would incur losses on both the Treasury security futures contracts written by it and the tax-exempt securities held in its portfolio.

Government Mortgage-Related Securities

The Government National Mortgage Association (“GNMA”) is the principal federal government guarantor of mortgage-related securities. GNMA is a wholly owned U.S. Government corporation within the Department of Housing and Urban Development. It guarantees, with the full faith and credit of the United States, full and timely payment of all monthly principal and interest on its mortgage-related securities. GNMA pass-through securities are considered to have a relatively low risk of default in that (1) the underlying mortgage loan portfolio is comprised entirely of government-backed loans and (2) the timely payment of both principal and interest on the securities is guaranteed by the full faith and credit of the U.S. Government, regardless of whether they have been collected. GNMA pass-through securities are, however, subject to the same interest rate risk as comparable privately issued mortgage-related securities. Therefore, the effective maturity and market value of the Fund’s GNMA securities can be expected to fluctuate in response to changes in interest rate levels.

Residential mortgage loans are also pooled by the Federal Home Loan Mortgage Corporation (“FHLMC”), a corporate instrumentality of the U.S. Government. The mortgage loans in FHLMC’s portfolio are not government backed; FHLMC, not the U.S. Government, guarantees the timely payment of interest and ultimate collection of principal on FHLMC securities. FHLMC also issues guaranteed mortgage certificates, on which it guarantees semiannual interest payments and a specified minimum annual payment of principal.

The Federal National Mortgage Association (“FNMA”) is a government-sponsored corporation owned entirely by private stockholders. It is subject to general regulation by the Secretary of Housing and Urban Development. FNMA purchases residential mortgages from a list of approved seller/servicers, which include savings and loan associations, savings banks, commercial banks, credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest only by FNMA, not the U.S. Government.

High Yield Securities

The Fund may invest a portion of its assets in high yield debt securities (commonly known as “junk bonds”). Investment in high yield securities generally provides greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and credit risk. These high yield securities are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of debt securities that are high yield may be more complex than for issuers of higher quality debt securities. In addition, high yield securities are often issued by smaller, less creditworthy companies or by highly leveraged (indebted) firms, but can also be issued by governments. Such issuers are generally less able than more financially stable issuers to make scheduled payments of interest and principal. The risks posed by securities issued under such circumstances are substantial.

Investing in high yield debt securities involves risks that are greater than the risks of investing in higher quality debt securities. These risks include: (i) changes in credit status, including weaker overall credit conditions of issuers and risks of default; (ii) industry, market and economic risk; and (iii) greater price variability and credit risks of certain high yield securities such as zero coupon and payment-in-kind securities. While these risks provide the opportunity for maximizing return over time, they may result in greater volatility of the value of the Fund than a fund that invests in higher-rated securities.

Furthermore, the value of high yield securities may be more susceptible to real or perceived adverse economic, company or industry conditions than is the case for higher quality securities. The market values of certain of these lower-rated and unrated debt securities tend to reflect individual issuer developments to a greater extent than do higher-rated securities which react primarily to fluctuations in the general level of interest rates, and tend to be more sensitive to economic conditions than are higher-rated securities. Adverse market, credit or economic conditions could make it difficult at certain times to sell certain high yield securities held by the Fund.

The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield security, and could adversely affect the daily net asset value (“NAV”) per share of the Fund. When secondary markets for high yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because there is less reliable, objective data available. However, an index seeks to include primarily high yield securities that the index provider believes have greater liquidity than the broader high yield securities market as a whole.

The use of credit ratings as a principal method of selecting high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated.

Illiquid Securities

The Fund may invest in illiquid securities. The Fund will invest no more than 15% of its net assets in illiquid securities, including repurchase agreements and time deposits of more than seven days’ duration. The absence of a regular trading market for illiquid securities imposes additional risks on investments in these securities. Illiquid securities may be difficult to value and may often be disposed of only after considerable expense and delay.

Infrastructure-Related Companies Risk

Infrastructure-related companies include companies that primarily own, manage, develop and/or operate infrastructure assets, including transportation, utility, energy and/or telecommunications assets. Infrastructure-related businesses are subject to a variety of factors that may adversely affect their business or operations, including high interest costs in connection with capital construction programs, insurance costs, costs associated with environmental and other regulations, the effects of an economic slowdown, surplus capacity or technological obsolescence, industry competition, labor relations, rate caps or rate changes, uncertainties concerning availability of fuel at reasonable prices, the effects of energy conservation policies, natural disasters, terrorist attacks and other factors. Certain infrastructure-related entities, particularly telecommunications and utilities companies, are subject to extensive regulation by various governmental authorities. The costs of complying with governmental regulations, delays or failures to receive required regulatory approvals or the enactment of new adverse regulatory requirements may adversely affect infrastructure-related companies. Infrastructure-related companies may also be affected by service interruption and/or legal challenges due to environmental, operational or other conditions or events, and the imposition of special tariffs and changes in tax laws, regulatory policies and accounting standards. There is also the risk that corruption may negatively affect publicly-funded infrastructure projects, especially in non-U.S. markets, resulting in work stoppage, delays and cost overruns. Other risks associated with infrastructure-related companies include uncertainties resulting from such companies’ diversification into new domestic and international businesses, as well as agreements by any such companies linking future rate increases to inflation or other factors not directly related to the actual operating profits of the enterprise.

Investment Grade Bonds

The Fund may invest in corporate notes and bonds that are rated investment-grade by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, are of comparable quality to the rated securities described above, as determined by the Adviser, in accordance with procedures established by the Board of Trustees. Investment-grade securities include securities rated Baa or higher by Moody’s or BBB- or higher by S&P (and securities of comparable quality); securities rated Baa by Moody’s or BBB by S&P may have speculative characteristics.

Lending of Fund Securities

The Fund may lend portfolio securities to certain creditworthy borrowers in U.S. and non-U.S. markets in an amount not to exceed 40% of the value of its net assets. The borrowers provide collateral that is marked to market daily in an amount at least equal to the current market value of the securities loaned. The Fund may terminate a loan at any time and obtain the securities loaned. The Fund receives the value of any interest or cash or non-cash distributions paid on the loaned securities. The Fund cannot vote proxies for securities on loan, but may recall loans to vote proxies if a material issue affecting the Fund’s economic interest in the investment is to be voted upon. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities, and may involve expenses to the Fund. Distributions received on loaned securities in lieu of dividend payments (i.e., substitute payments) would not be considered qualified dividend income.

With respect to loans that are collateralized by cash, the borrower typically will be entitled to receive a fee based on the amount of cash collateral. The Fund is compensated by the difference between the amount earned on the reinvestment of cash collateral and the fee paid to the borrower. In the case of collateral other than cash, the Fund is compensated by a fee paid by the borrower equal to a percentage of the market value of the loaned securities. Any cash collateral may be reinvested in certain high quality short-term instruments either directly on behalf of the lending Fund or through one or more joint accounts or funds, which may include those managed by the Adviser. The Fund could lose money due to a decline in the value of collateral provided for loaned securities or any investments made with cash collateral. Certain non-cash collateral or investments made with cash collateral may have a greater risk of loss than other non-cash collateral or investments.

The Fund may pay a portion of the interest or fees earned from securities lending to a borrower as described above, and to one or more securities lending agents approved by the Board who administer the lending program for the Fund in accordance with guidelines approved by the Board. In such capacity, the lending agent provides the following services to the Fund in connection with the Fund’s securities lending activities: (i) locating borrowers among an approved list of prospective borrowers; (ii) causing the delivery of loaned securities from the Fund to borrowers; (iii) monitoring the value of loaned securities, the value of collateral received, and other lending parameters; (iv) seeking additional collateral, as necessary, from borrowers; (v) receiving and holding collateral from borrowers, and facilitating the investment and reinvestment of all or substantially all cash collateral in an investment vehicle designated by the Fund; (vi) returning collateral to borrowers; (vii) facilitating substitute dividend, interest, and other distribution payments to the Fund from borrowers; (viii) negotiating the terms of each loan of securities, including but not limited to the amount of

13

Table of Contents

any loan premium, and monitoring the terms of securities loan agreements with prospective borrowers for consistency with the requirements of the Fund’s Securities Lending Authorization Agreement; (ix) selecting securities, including amounts (percentages), to be loaned; (x) recordkeeping and accounting servicing; and (xi) arranging for return of loaned securities to the Fund in accordance with the terms of the Securities Lending Authorization Agreement. State Street Bank and Trust Company (“State Street”), an affiliate of the Trust, has been approved by the Board to serve as securities lending agent for the Fund and the Trust has entered into an agreement with State Street for such services. Among other matters, the Trust has agreed to indemnify State Street for certain liabilities. State Street has received an order of exemption from the SEC under Sections 17(a), 17(d) and 12(d)(1) under the 1940 Act to serve as the lending agent for affiliated investment companies such as the Trust, to invest the cash collateral received from loan transactions in an affiliated cash collateral fund and to receive a fee based on a share of the revenue generated from such transactions.

Securities lending involves exposure to certain risks, including operational risk (i.e., the risk of losses resulting from problems in the settlement and accounting process especially so in certain international markets such as Taiwan), “gap” risk (i.e., the risk of a mismatch between the return on cash collateral reinvestments and the fees the Fund has agreed to pay a borrower), risk of loss of collateral, credit, legal, counterparty and market risk. If a securities lending counterparty were to default, the Fund would be subject to the risk of a possible delay in receiving collateral (or the proceeds of its liquidation) or in recovering the loaned securities. In the event a borrower does not return the Fund’s securities as agreed, the Fund may experience losses if the proceeds received from liquidating the collateral do not at least equal the value of the loaned security at the time the collateral is liquidated, plus the transaction costs incurred in purchasing replacement securities. Although State Street has agreed to provide the Fund with indemnification in the event of a borrower default, the Fund is still exposed to the risk of losses in the event a borrower does not return the Fund’s securities as agreed. For example, delays in recovery of lent securities may cause the Fund to lose the opportunity to sell the securities at a desirable price with guaranteed delivery provisions.

Market Disruption and Geopolitical Risk

The Fund is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. War, terrorism, and related geopolitical events have led, and in the future may lead, to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets generally. Likewise, natural and environmental disasters and systemic market dislocations may be highly disruptive to economies and markets. Those events as well as other changes in non-U.S. and domestic economic and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Fund’s investments. Given the increasing interdependence between global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the U.S. Continuing uncertainty as to the status of the Euro and the European Monetary Union (the “EMU”) has created significant volatility in currency and financial markets generally. Any partial or complete dissolution of the EMU, or any continued uncertainty as to its status, could have significant adverse effects on currency and financial markets, and on the values of the Fund’s investments.

Securities markets may be susceptible to market manipulation (e.g., the potential manipulation of LIBOR) or other fraudulent trade practices, which could disrupt the orderly functioning of these markets or adversely affect the value of investments traded in these markets, including investments of the Fund.

Recent political activity in the U.S. has increased the risk that the U.S. could default on some or any of its obligations. While it is impossible to predict the consequences of such an unprecedented event, it is likely that a default by the U.S. would be highly disruptive to the U.S. and global securities markets and could significantly impair the value of the Fund’s investments. Similarly, political events within the U.S. at times have resulted, and may in the future result, in a shutdown of government services, which could negatively affect the U.S. economy, decrease the value of many Fund investments, and increase uncertainty in or impair the operation of the U.S. or other securities markets. To the extent the Fund has focused its investments in the stock market index of a particular region, adverse geopolitical and other events could have a disproportionate impact on the Fund.

Mortgage-Backed Security Rolls

The Fund may enter into “forward roll” transactions with respect to mortgage-related securities issued by GNMA, FNMA or FHLMC. In a forward roll transaction, the Fund will sell a mortgage-related security to a bank or other permitted entity and simultaneously agree to repurchase a similar security from the institution at a later date at an agreed upon price. The mortgage securities that are repurchased will typically bear the same interest rate as those sold, but generally will be collateralized by different pools of mortgages with different prepayment histories than those sold. If the Fund engages in a forward roll transaction, it will forgo principal and interest paid on the securities sold during the roll period, but is compensated by the difference between the current sales price and the lower forward price for the future purchase. In addition, the Fund earns interest by investing the transaction proceeds during the roll period. A forward roll transaction may create investment leverage. The Fund is subject to the risk that the value of securities to be purchased pursuant to a forward roll transaction will decline over the roll period, and that the Fund’s counterparty may be unwilling or unable to perform its obligations to the Fund. Upon entering into a mortgage-backed security roll, the Fund will segregate on its records cash, U.S. Government securities or other high-grade debt securities in an amount sufficient to cover its obligation under the roll.

Mortgage-Related Securities

The Fund may invest in mortgage-related securities. Mortgage-related securities represent an interest in a pool of, or are secured by, mortgage loans. Mortgage-related securities may be issued or guaranteed by (i) U.S. Government agencies or instrumentalities such as GNMA, FNMA and FHLMC or (ii) other issuers, including private companies.

Many mortgage-related securities provide regular payments which consist of interest and, in most cases, principal. In contrast, other forms of debt securities normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. In effect, payments on many mortgage-related securities are a “pass-through” of the payments made by the individual borrowers on their mortgage loans, net of any fees paid to the issuer or guarantor of such securities.

Besides the scheduled repayment of principal, repayments of principal may result from the voluntary prepayment, refinancing or foreclosure of the underlying mortgage loans. If property owners make unscheduled prepayments of their mortgage loans, these prepayments will typically result in early payment of the applicable mortgage-related securities. The occurrence of mortgage prepayments is affected by a variety of factors including the level of interest rates, general economic conditions, the location and age of the mortgage, and other social and demographic conditions. During periods of falling interest rates, the rate of mortgage prepayments tends to increase, thereby tending to decrease the life of mortgage-related securities. During periods of rising interest rates, the rate of mortgage prepayments usually decreases, thereby tending to increase the life of mortgage-related securities.

Because of the possibility of prepayments (and due to scheduled repayments of principal), mortgage-related securities are less effective than other types of securities as a means of “locking in” attractive long-term interest rates. Prepayments would have to be reinvested at lower rates. As a result, these securities may have less potential for capital appreciation during periods of declining interest rates than other securities of comparable maturities, although they may have a similar risk of decline in market value during periods of rising interest rates. Prepayments may also significantly shorten the effective maturities of these securities, especially during periods of declining interest rates. Conversely, during periods of rising interest rates, a reduction in prepayments may increase the effective maturities of these securities, subjecting them to a greater risk of decline in market value in response to rising interest rates than traditional debt securities, and, therefore, potentially increasing the volatility of the Fund.

Collateralized mortgage obligations (“CMOs”) may be issued by a U.S. Government agency or instrumentality or by a private issuer. CMOs are typically structured with classes or series that have different maturities and are generally retired in sequence. Each class of obligations receives periodic interest payments according to its terms. However, monthly principal payments and any prepayments from the collateral pool are generally paid first to the holders of the most senior class. Thereafter, payments of principal are generally allocated to the next most senior class of obligations until that class of obligations has been fully repaid. Any or all classes of obligations of a CMO may be paid off sooner than expected because of an increase in the payoff speed of the pool. Changes in prepayment rates may have significant effects on the values and the volatility of the various classes and series of a CMO. Payment of interest or principal on some classes or series of a CMO may be subject to contingencies or some classes or series may bear some or all of the risk of default on the underlying mortgages.

Stripped mortgage-related securities are usually structured with two classes that receive different portions of the interest and principal distributions on a pool of mortgage loans. The yield to maturity on an interest only or “IO” class of stripped mortgage-related securities is extremely sensitive not only to changes in prevailing interest rates but also to the rate of principal payments (including prepayments) on the underlying assets. A rapid rate of principal prepayments may have a measurable adverse effect on the Fund’s yield to maturity to the extent it invests in IOs. If the assets underlying the IO experience greater than anticipated prepayments of principal, the Fund may fail to recoup fully, or at all, its initial investment in these securities. Conversely, principal only securities or “POs” tend to increase in value if prepayments are greater than anticipated and decline if prepayments are slower than anticipated. The secondary market for stripped mortgage-related securities may be more volatile and less liquid than that for other mortgage-related securities, potentially limiting the Fund’s ability to buy or sell those securities at any particular time.

Municipal and Municipal-Related Securities

Municipal securities may bear fixed, floating or variable rates of interest or may be zero coupon securities. Municipal securities are generally of two types: general obligations and revenue obligations. General obligations are backed by the full faith and credit of the issuer. These securities include tax anticipation notes, bond anticipation notes, general obligation bonds and commercial paper. Revenue obligations are backed by the revenues generated from a specific project or facility and include industrial development bonds and private activity bonds. Tax anticipation notes are issued to finance working capital needs of municipalities and are generally issued in anticipation of future tax revenues. Bond anticipation notes are issued in expectation of the issuer obtaining longer-term financing.

Options

The Fund may purchase and sell put and call options to enhance investment performance and to protect against changes in market prices. There is no assurance that the Fund’s use of put and call options will achieve its desired objective, and the Fund’s use of options may result in losses to the Fund.

Covered call options. The Fund may write (i.e., sell) covered call options to realize a greater current return through the receipt of premiums than it would realize on its securities alone. Such option transactions may also be used as a limited form of hedging against a decline in the price of securities owned by the Fund.

A call option gives the holder the right to purchase, and obligates the writer to sell, a security at the exercise price at any time before the expiration date. A call option is “covered” if the writer, at all times while obligated as a writer, either owns the underlying securities (or comparable securities satisfying the cover requirements of the securities exchanges), or has the right to acquire such securities through immediate conversion of securities. The Fund may write covered call options or uncovered call options.

The Fund will receive a premium from writing a call option, which increases the Fund’s return on the underlying security in the event the option expires unexercised or is closed out at a profit. The amount of the premium reflects, among other things, the relationship between the exercise price and the current market value of the underlying security, the volatility of the underlying security, the amount of time remaining until expiration, current interest rates, and the effect of supply and demand in the options market and in the market for the underlying security.

In return for the premium received when it writes a covered call option, the Fund gives up some or all of the opportunity to profit from an increase in the market price of the securities covering the call option during the life of the option. The Fund retains the risk of loss should the price of such securities decline. If the option expires unexercised, the Fund realizes a gain equal to the premium, which may be offset by a decline in price of the underlying security. If the option is exercised, the Fund realizes a gain or loss equal to the difference between the Fund’s cost for the underlying security and the proceeds of sale (exercise price minus commissions) plus the amount of the premium.

The Fund may terminate a call option that it has written before it expires by entering into a closing purchase transaction. The Fund may enter into closing purchase transactions in order to free itself to sell the underlying security or to write another call on the security, realize a profit on a previously written call option, or protect a security from being called in an unexpected market rise. Any profits from a closing purchase transaction may be offset by a decline in the value of the underlying security. Conversely, because increases in the market price of a call option will generally reflect increases in the market price of the underlying security, any loss resulting from a closing purchase transaction is likely to be offset in whole or in part by unrealized appreciation of the underlying security owned by the Fund.

Uncovered call options. Writing uncovered call options may enable the Fund to realize income without committing capital to the ownership of the underlying securities or instruments, however writing uncovered calls are riskier than writing covered calls because there is no underlying security held by the Fund that can act as a partial hedge. When the Fund has written an uncovered call option, the Fund will not necessarily hold securities offsetting the risk to the Fund. As a result of writing a call option without holding the underlying the securities, if the call option were exercised, the Fund might be required to purchase the security that is the subject of the call at the market price at the time of exercise. The Fund’s exposure on such an option is theoretically unlimited. There is also a risk, especially with less liquid preferred and debt securities, that the security may not be available for purchase. Uncovered calls have speculative characteristics.

Covered put options. The Fund may write covered put options in order to enhance its current return. Such options transactions may also be used as a limited form of hedging against an increase in the price of securities that the Fund plans to purchase. A put option gives the holder the right to sell, and obligates the writer to buy, a security at the exercise price at any time before the expiration date. A put option may be “covered” if the writer earmarks or otherwise segregates liquid assets equal to the price to be paid if the option is exercised minus margin on deposit.

By writing a put option, the Fund assumes the risk that it may be required to purchase the underlying security for an exercise price higher than its then current market value, resulting in a potential capital loss unless the security later appreciates in value.

The Fund may terminate a put option that it has written before it expires by entering into a closing purchase transaction. Any loss from this transaction may be partially or entirely offset by the premium received on the terminated option.

Purchasing put and call options. The Fund may also purchase put options to protect portfolio holdings against a decline in market value. This protection lasts for the life of the put option because the Fund, as a holder of the option, may sell the underlying security at the exercise price regardless of any decline in its market price. In order for a put option to be profitable, the market price of the underlying security must decline sufficiently below the exercise price to cover the premium and transaction costs that the Fund must pay. These costs will reduce any profit the Fund might have realized had it sold the underlying security instead of buying the put option.

16

Table of Contents

The Fund may purchase call options to hedge against an increase in the price of securities that the Fund wants ultimately to buy. Such hedge protection is provided during the life of the call option since the Fund, as holder of the call option, is able to buy the underlying security at the exercise price regardless of any increase in the underlying security’s market price. In order for a call option to be profitable, the market price of the underlying security must rise sufficiently above the exercise price to cover the premium and transaction costs. These costs will reduce any profit the Fund might have realized had it bought the underlying security at the time it purchased the call option.

The Fund may also purchase put and call options to attempt to enhance its current return.

Options on foreign securities. The Fund may purchase and sell options on foreign securities if the Adviser believes that the investment characteristics of such options, including the risks of investing in such options, are consistent with the Fund’s investment objective. It is expected that risks related to such options will not differ materially from risks related to options on U.S. securities. However, position limits and other rules of foreign exchanges may differ from those in the United States. In addition, options markets in some countries, many of which are relatively new, may be less liquid than comparable markets in the United States.

Options on securities indices

The Fund may write or purchase options on securities indices. Index options are similar to options on individual securities in that the purchaser of an index option acquires the right to buy (in the case of a call) or sell (in the case of a put), and the writer undertakes the obligation to sell or buy (as the case may be), units of an index at a stated exercise price during the term of the option. Instead of the right to take or make actual delivery of securities, the holder of an index option has the right to receive a cash “exercise settlement amount.” This amount is equal to the amount by which the fixed exercise price of the option exceeds (in the case of a put) or is less than (in the case of a call) the closing value of the underlying index on the date of the exercise, multiplied by a fixed “index multiplier.”

Price movements in securities which the Fund owns or intends to purchase probably will not correlate perfectly with movements in the level of a securities index and, therefore, if the Fund uses an option for hedging purposes, it bears the risk of a loss on a securities index option which is not completely offset by movements in the price of such securities. Because securities index options are settled in cash, a call writer cannot determine the amount of its settlement obligations in advance and, unlike call writing on a specific security, cannot provide in advance for, or cover, its potential settlement obligations by acquiring and holding underlying securities. The Fund may, however, cover call options written on a securities index by holding a mix of securities which substantially replicate the movement of the index or by holding a call option on the securities index with an exercise price no higher than the call option sold.

Compared to the purchase or sale of futures contracts, the purchase of call or put options on an index involves less potential risk to the Fund because the maximum amount at risk is the premium paid for the options plus transactions costs. The writing of a put or call option on an index involves risks similar to those risks relating to the purchase or sale of index futures contracts.

Risks involved in the use of options. The successful use of the Fund’s options strategies depends on the ability of the Adviser to forecast correctly interest rate and market movements. For example, if the Fund were to write a call option based on the Adviser’s expectation that the price of the underlying security would fall, but the price were to rise instead, the Fund could be required to sell the security upon exercise at a price below the current market price. Similarly, if the Fund were to write a put option based on the Adviser’s expectation that the price of the underlying security would rise, but the price were to fall instead, the Fund could be required to purchase the security upon exercise at a price higher than the current market price.

When the Fund purchases an option, it runs the risk that it will lose its entire investment in the option in a relatively short period of time, unless the Fund exercises the option or enters into a closing sale transaction before the option’s expiration. If the price of the underlying security does not rise (in the case of a call) or fall (in the case of a put) to an extent sufficient to cover the option premium and transaction costs, the Fund will lose part or all of its investment in the option. This contrasts with an investment by the Fund in the underlying security, since the Fund will not realize a loss if the security’s price does not change.

The effective use of options also depends on the Fund’s ability to terminate option positions at times when the Adviser deems it desirable to do so. There is no assurance that the Fund will be able to effect closing transactions at any particular time or at an acceptable price.

If a secondary market in options were to become unavailable, the Fund could no longer engage in closing transactions. Lack of investor interest might adversely affect the liquidity of the market for particular options or series of options. A market may discontinue trading of a particular option or options generally. In addition, a market could become temporarily unavailable if unusual events — such as volume in excess of trading or clearing capability — were to interrupt its normal operations.

A market may at times find it necessary to impose restrictions on particular types of options transactions, such as opening transactions. For example, if an underlying security ceases to meet qualifications imposed by the market or the Options Clearing Corporation, new series of options on that security will no longer be opened to replace expiring series, and opening transactions in existing series may be prohibited. If an options market were to become unavailable, the Fund as a holder of an option would be able to realize profits or limit losses only by exercising the option, and the Fund, as option writer, would remain obligated under the option until expiration or exercise.

Disruptions in the markets for the securities underlying options purchased or sold by the Fund could result in losses on the options. If trading is interrupted in an underlying security, the trading of options on that security is normally halted as well. As a result, the Fund as purchaser or writer of an option will be unable to close out its positions until options trading resumes, and it may be faced with considerable losses if trading in the security reopens at a substantially different price. In addition, the Options Clearing Corporation or options markets may impose exercise restrictions. If a prohibition on exercise is imposed at the time when trading in the option has also been halted, the Fund as purchaser or writer of an option will be locked into its position until one of the two restrictions has been lifted. If the Options Clearing Corporation were to determine that the available supply of an underlying security appears insufficient to permit delivery by the writers of all outstanding calls in the event of exercise, it may prohibit indefinitely the exercise of put options. The Fund, as holder of such a put option, could lose its entire investment if the prohibition remained in effect until the put option’s expiration.

Foreign-traded options are subject to many of the same risks presented by internationally-traded securities. In addition, because of time differences between the United States and various foreign countries, and because different holidays are observed in different countries, foreign options markets may be open for trading during hours or on days when U.S. markets are closed. As a result, option premiums may not reflect the current prices of the underlying interest in the United States.

Over-the-counter (“OTC”) options purchased by the Fund and assets held to cover OTC options written by the Fund may, under certain circumstances, be considered illiquid securities for purposes of any limitation on the Fund’s ability to invest in illiquid securities.

Other Asset-Backed Securities

In addition to the mortgage related securities discussed above, the Fund may invest in asset-backed securities that are not mortgage-related. Asset-backed securities other than mortgage-related securities represent undivided fractional interests in pools of instruments, such as consumer loans, and are typically similar in structure to mortgage-related pass-through securities. Payments of principal and interest are passed through to holders of the securities and are typically supported by some form of credit enhancement, such as a letter of credit, surety bond, limited guarantee by another entity, or by priority to certain of the borrower’s other securities. The degree of credit-enhancement, if any, varies, applying only until exhausted and generally covering only a fraction of the security’s par value.

The value of such asset-backed securities is affected by changes in the market’s perception of the asset backing the security, changes in the creditworthiness of the servicing agent for the instrument pool, the originator of the instruments, or the financial institution providing any credit enhancement and the expenditure of any portion of any credit enhancement. The risks of investing in asset-backed securities are ultimately dependent upon payment of the underlying instruments by the obligors, and the Fund would generally have no recourse against the obligee of the instruments in the event of default by an obligor. The underlying instruments are subject to prepayments which shorten the duration of asset-backed securities and may lower their return, in generally the same manner as described above for prepayments of pools of mortgage loans underlying mortgage-related securities.

Private Placements and Restricted Securities

The Fund may invest in securities that are purchased in private placements and, accordingly, are subject to restrictions on resale as a matter of contract or under federal securities laws. While such private placements may offer attractive opportunities for investment not otherwise available on the open market, the securities so purchased are often “restricted securities,” i.e., securities which cannot be sold to the public without registration under the Securities Act of 1933 (the “Securities Act”) or the availability of an exemption from registration (such as Rules 144 or 144A), or which are not readily marketable because they are subject to other legal or contractual delays in or restrictions on resale. Generally speaking, restricted securities may be sold only to qualified institutional buyers, or in a privately negotiated transaction to a limited number of purchasers, or in limited quantities after they have been held for a specified period of time and other conditions are met pursuant to an exemption from registration, or in a public offering for which a registration statement is in effect under the Securities Act.

Because there may be relatively few potential purchasers for such investments, especially under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when the Adviser believes it advisable to do so or may be able to sell such securities only at prices lower than if such securities were more widely held. Market quotations for such securities are generally less readily available than for publicly traded securities. The absence of a trading market can make it difficult to ascertain a market value for such securities for purposes of computing the Fund’s net asset value, and the judgment of the Adviser may at times play a greater role in valuing these securities than in the case of publicly traded securities. Disposing of such securities, which may be illiquid investments, can involve time-consuming negotiation and legal expenses, and it may be difficult or impossible for the Fund to sell them promptly at an acceptable price. The Fund may have to bear the extra expense of registering such securities for resale and the risk of substantial delay in effecting such registration.

The Fund may be deemed to be an “underwriter” for purposes of the Securities Act when selling restricted securities to the public, and in such event the Fund may be liable to purchasers of such securities if the registration statement prepared by the issuer, or the prospectus forming a part of it, is materially inaccurate or misleading.

Pre-Refunded Municipal Securities

The interest and principal payments on pre-refunded municipal securities are typically paid from the cash flow generated from an escrow fund consisting of U.S. Government securities. These payments have been “pre-refunded” using the escrow fund.

Purchase of Other Investment Company Shares

The Fund may, to the extent permitted under the 1940 Act and exemptive rules and orders thereunder, invest in shares of other investment companies, which include funds managed by SSGA FM, which invest exclusively in money market instruments or in investment companies with investment policies and objectives which are substantially similar to those of the Fund. These investments may be made temporarily, for example, to invest uncommitted cash balances or, in limited circumstances, to assist in meeting shareholder redemptions, or as long-term investments.

Real Estate Investment Trusts (“REITs”)

The Fund may invest in REITs. REITs pool investors’ funds for investment primarily in income producing real estate or real estate loans or interests. A REIT is not taxed on income distributed to shareholders if it complies with several requirements relating to its organization, ownership, assets, and income and a requirement that it distribute to its shareholders at least 90% of its taxable income (other than net capital gains) for each taxable year. REITs can generally be classified as Equity REITs, Mortgage REITs and Hybrid REITs. Equity REITs, which invest the majority of their assets directly in real property, derive their income primarily from rents. Equity REITs can also realize capital gains by selling properties that have appreciated in value. Mortgage REITs, which invest the majority of their assets in real estate mortgages, derive their income primarily from interest payments. Hybrid REITs combine the characteristics of both Equity REITs and Mortgage REITs. The Fund will not invest in real estate directly, but only in securities issued by real estate companies. However, the Fund may be subject to risks similar to those associated with the direct ownership of real estate (in addition to securities markets risks) because of its policy of concentration in the securities of companies in the real estate industry. These include declines in the value of real estate, risks related to general and local economic conditions, dependency on management skill, heavy cash flow dependency, possible lack of availability of mortgage funds, overbuilding, extended vacancies of properties, increased competition, increases in property taxes and operating expenses, changes in zoning laws, losses due to costs resulting from the clean-up of environmental problems, liability to third parties for damages resulting from environmental problems, casualty or condemnation losses, limitations on rents, changes in neighborhood values, the appeal of properties to tenants and changes in interest rates. Investments in REITs may subject Fund shareholders to duplicate management and administrative fees.

In addition to these risks, Equity REITs may be affected by changes in the value of the underlying property owned by the trusts, while Mortgage REITs may be affected by the quality of any credit extended. Further, Equity and Mortgage REITs are dependent upon management skills and generally may not be diversified. Equity and Mortgage REITs are also subject to heavy cash flow dependency, defaults by borrowers and self-liquidation. In addition, if applicable, Equity and Mortgage REITs could possibly fail to qualify for the beneficial tax treatment available to REITs under the Code, or to maintain their exemptions from registration under the 1940 Act. The above factors may also adversely affect a borrower’s or a lessee’s ability to meet its obligations to the REIT. In the event of a default by a borrower or lessee, the REIT may experience delays in enforcing its rights as a mortgagee or lessor and may incur substantial costs associated with protecting investments.

Repurchase Agreements

The Fund may enter into repurchase agreements with banks, other financial institutions, such as broker-dealers, and other institutional counterparties. Under a repurchase agreement, the Fund purchases securities from a financial institution that agrees to repurchase the securities at the Fund’s original purchase price plus interest within a specified time. The Fund will limit repurchase transactions to those member banks of the Federal Reserve System, broker-dealers and other financial institutions whose creditworthiness the Adviser considers satisfactory. Should the counterparty to a transaction fail financially, the Fund may encounter delay and incur costs before being able to sell the securities, or may be prevented from realizing on the securities. Further, the amount realized upon the sale of the securities may be less than that necessary to fully compensate the Fund.

Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements, which are a form of borrowing. Under reverse repurchase agreements, the Fund transfers possession of portfolio securities to financial institutions in return for cash in an amount equal to a percentage of the portfolio securities’ market value and agrees to repurchase the securities at a future date by repaying the cash with interest. The Fund retains the right to receive interest and principal payments from the securities. Cash or liquid high quality debt obligations from the Fund’s portfolio equal in value to the repurchase price including any accrued interest will be segregated by the Custodian on the Fund’s records while a reverse repurchase agreement is in effect. Reverse repurchase agreements involve the risk that the market value of securities sold by the Fund may decline below the price at which it is obligated to repurchase the securities. Reverse repurchase agreements involve the risk that the buyer of the securities sold might be unable to deliver them when the Fund seeks to repurchase the securities. If the buyer files for bankruptcy or becomes insolvent, the Fund may be delayed or prevented from recovering the security that it sold.

Special Risk Considerations of Investing in China

The Fund may invest in securities of Chinese issuers. Investing in securities of Chinese issuers, including by investing in A Shares, involves certain risks and considerations not typically associated with investing in securities of U.S. issuers, including, among others, (i) more frequent (and potentially widespread) trading suspensions and government interventions with respect to Chinese issuers, resulting in a lack of liquidity and in price volatility, (ii) currency revaluations and other currency exchange rate fluctuations or blockage, (iii) the nature and extent of intervention by the Chinese government in the Chinese securities markets, whether such intervention will continue and the impact of such intervention or its discontinuation, (iv) the risk of nationalization or expropriation of assets, (v) the risk that the Chinese government may decide not to continue to support economic reform programs, (vi) limitations on the use of brokers, (vii) potentially higher rates of inflation, (viii) the unavailability of consistently-reliable economic data, (ix) the relatively small size and absence of operating history of many Chinese companies, (x) accounting, auditing and financial reporting standards in China are different from U.S. standards and, therefore, disclosure of certain material information may not be available, (xi) greater political, economic, social, legal and tax-related uncertainty, (xii) higher market volatility caused by any potential regional territorial conflicts or natural disasters, (xiii) higher dependence on exports and international trade, (xiv) the risk of increased trade tariffs, embargoes and other trade limitations, (xv) restrictions on foreign ownership, and (xvi) custody risks associated with investing through programs to access Chinese securities. Significant portions of the Chinese securities markets may become rapidly illiquid, as Chinese issuers have the ability to suspend the trading of their equity securities, and have shown a willingness to exercise that option in response to market volatility and other events. The liquidity of Chinese securities may shrink or disappear suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.

Total Return Swaps, Equity Swaps and Interest Rate Swaps

The Fund may contract with a counterparty to pay a stream of cash flows and receive the total return of an index or a security for purposes of attempting to obtain a particular desired return at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return. The Fund’s return on a swap will depend on the ability of its counterparty to perform its obligations under the swap. The Adviser will cause the Fund to enter into swap agreements only with counterparties that would be eligible for consideration as repurchase agreement counterparties under the Fund’s repurchase agreement guidelines.

The Fund may enter into interest rate swap transactions with respect to any security they are entitled to hold. Interest rate swaps involve the exchange by the Fund with another party of their respective rights to receive interest, e.g., an exchange of floating rate payments for fixed rate payments. The Fund expects to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio or to protect against any increase in the price of securities it anticipates purchasing at a later date. The Fund generally intends to use these transactions as a hedge and not as a speculative investment. For example, the Fund may enter into an interest rate swap in order to protect against declines in the value of fixed income securities held by the Fund. In such an instance, the Fund may agree with a counterparty to pay a fixed rate (multiplied by a notional amount) and the counterparty to pay a floating rate multiplied by the same notional amount. If interest rates rise, resulting in a diminution in the value of the Fund, the Fund would receive payments under the swap that would offset, in whole or in part, such diminution in value; if interest rates fall, the Fund would likely lose money on the swap transaction.

Treasury Inflation-Protected Securities

The Fund may invest in Inflation-Protection Securities (“TIPSs”), a type of inflation-indexed Treasury security. TIPSs typically provide for semiannual payments of interest and a payment of principal at maturity. In general, each payment will be adjusted to take into account any inflation or deflation that occurs between the issue date of the security and the payment date based on the Consumer Price Index for All Urban Consumers (“CPI-U”).

Each semiannual payment of interest will be determined by multiplying a single fixed rate of interest by the inflation-adjusted principal amount of the security for the date of the interest payment. Thus, although the interest rate will be fixed, the amount of each interest payment will vary with changes in the principal of the security as adjusted for inflation and deflation.

TIPSs also provide for an additional payment (a “minimum guarantee payment”) at maturity if the security’s inflation-adjusted principal amount for the maturity date is less than the security’s principal amount at issuance. The amount of the additional payment will equal the excess of the security’s principal amount at issuance over the security’s inflation-adjusted principal amount for the maturity date.

U.S. Government Securities

The Fund may purchase U.S. Government securities. The types of U.S. Government obligations in which the Fund may at times invest include: (1) U.S. Treasury obligations and (2) obligations issued or guaranteed by U.S. Government agencies and instrumentalities which are supported by any of the following: (a) the full faith and credit of the U.S. Treasury, (b) the right of the issuer to borrow an amount limited to a specific line of credit from the U.S. Treasury, (c) discretionary authority of the U.S. Government agency or instrumentality, or (d) the credit of the instrumentality (examples of agencies and instrumentalities are: Federal Land Banks, Federal Housing Administration, Federal Farm Credit Bank, Farmers Home Administration, Export-Import Bank of the United States, Central Bank for Cooperatives, Federal Intermediate Credit Banks, Federal Home Loan Banks, General Services Administration, Maritime Administration, Tennessee Development Bank, Asian-American Development Bank, International Bank for Reconstruction and Development and FNMA). No assurance can be given that in the future the U.S. Government will provide financial support to U.S. Government securities it is not obligated to support.

U.S. Registered Securities of Non-U.S. Issuers

The Fund may purchase publicly traded common stocks of non-U.S. corporations.

Investing in U.S. registered, dollar-denominated, securities issued by non-U.S. issuers involves some risks and considerations not typically associated with investing in U.S. companies. These include differences in accounting, auditing and financial reporting standards, the possibility of expropriation or confiscatory taxation, adverse changes in investment or exchange control regulations, political instability which could affect U.S. investments in non-U.S. countries, and potential restrictions of the flow of international capital. Non-U.S. companies may be subject to less governmental regulation than U.S. issuers. Moreover, individual non-U.S. economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross domestic product, rate of inflation, capital reinvestment, resource self-sufficiency and balance of payment positions.

The Fund’s investment in common stock of non-U.S. corporations may also be in the form of American Depositary Receipts (“ADRs”), Global Depositary Receipts (“GDRs”) and European Depositary Receipts (“EDRs”) (collectively “Depositary Receipts”). Depositary Receipts are receipts, typically issued by a bank or trust company, which evidence ownership of underlying securities issued by a non-U.S. corporation. For ADRs, the depository is typically a U.S. financial institution and the underlying securities are issued by a non-U.S. issuer. For other Depositary Receipts, the depository may be a non-U.S. or a U.S. entity, and the underlying securities may have a non-U.S. or a U.S. issuer. Depositary Receipts will not necessarily be denominated in the same currency as their underlying securities. Generally, ADRs, in registered form, are designed for use in the U.S. securities markets, and EDRs, in bearer form, are designated for use in European securities markets. GDRs are tradable both in the United States and in Europe and are designed for use throughout the world. The Fund may invest in unsponsored Depositary Receipts. The issuers of unsponsored Depositary Receipts are not obligated to disclose material information in the United States, and, therefore, there may be less information available regarding such issuers and there may not be a correlation between such information and the market value of the Depositary Receipts.

Variable Amount Master Demand Notes

The Fund may invest in variable amount master demand notes which are unsecured obligations that are redeemable upon demand and are typically unrated. These instruments are issued pursuant to written agreements between their issuers and holders. The agreements permit the holders to increase (subject to an agreed maximum) and the holders and issuers to decrease the principal amount of the notes, and specify that the rate of interest payable on the principal fluctuates according to an agreed formula. Generally, changes in interest rates will have a smaller effect on the market value of these securities than on the market value of comparable fixed income obligations. Thus, investing in these securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed income securities. There may be no active secondary market with respect to a particular variable rate instrument.

Variable and Floating Rate Securities

The Fund may invest in variable and floating rate securities. In general, variable rate securities are instruments issued or guaranteed by entities such as (1) U.S. Government, or an agency or instrumentality thereof, (2) corporations, (3) financial institutions, (4) insurance companies or (5) trusts that have a rate of interest subject to adjustment at regular intervals but less frequently than annually. A variable rate security provides for the automatic establishment of a new interest rate on set dates. Interest rates on these securities are ordinarily tied to widely recognized market rates, which are typically set once a day. These rates may change as often as twice daily. Generally, changes in interest rates will have a smaller effect on the market value of variable and floating rate securities than on the market value of comparable fixed income obligations. Thus, investing in variable and floating rate securities generally allows less opportunity for capital appreciation and depreciation than investing in comparable fixed income securities. Variable rate obligations will be deemed to have a maturity equal to the period remaining until the next readjustment of the interest rate.

Many financial instruments use or may use a floating rate based on LIBOR, which is the offered rate for short-term Eurodollar deposits between major international banks. On July 27, 2017, the head of the United Kingdom’s Financial Conduct Authority announced a desire to phase out the use of LIBOR by the end of 2021. There remains uncertainty regarding the future utilization of LIBOR and the nature of any replacement rate. As such, the potential effect of a transition away from LIBOR on the Fund or the financial instruments in which the Fund invests cannot yet be determined. The transition process might lead to increased volatility and illiquidity in markets that currently rely on LIBOR to determine interest rates. It could also lead to a reduction in the value of some LIBOR-based investments and reduce the effectiveness of new hedges placed against existing LIBOR-based instruments. Since the usefulness of LIBOR as a benchmark could deteriorate during the transition period, these effects could occur prior to the end of 2021.

When-Issued, Delayed Delivery and Forward Commitment Transactions

To secure an advantageous price or yield, the Fund may purchase securities on a when-issued, delayed delivery, to-be-announced (“TBA”) or forward commitment basis and may sell securities on a forward commitment or delayed delivery basis. The Fund will enter into when-issued, delayed delivery, TBA or forward commitment transactions for the purpose of acquiring securities and not for the purpose of leverage.

When purchasing a security on a when-issued, delayed delivery, TBA or forward commitment basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its NAV. When such transactions are negotiated, certain terms may be fixed at the time the commitment is made, but delivery and payment for the securities takes place at a later date. In general, the Fund does not pay for the securities until received and does not start earning interest or other income until the contractual settlement date. The Fund may take delivery of the securities or it may sell the securities before the settlement date.

At the time of delivery of the securities, the value may be more or less than the purchase or sale price. If the Fund remains substantially fully invested at a time when when-issued, delayed delivery, TBA or forward commitment purchases are outstanding, the purchases may result in a form of leverage and give rise to increased volatility of the Fund’s NAV. Default by, or bankruptcy of, a counterparty to a when-issued, delayed delivery, TBA or forward commitment transaction would expose the Fund to possible losses because of an adverse market action, expenses or delays in connection with the purchase or sale of the pools specified in such transaction. Purchases of when-issued, delayed delivery, TBA or forward commitment securities also involve a risk of loss if the seller fails to deliver after the value of the securities has risen.

Cash or other liquid assets in an amount equal to the amount of the Fund’s when-issued, delayed-delivery, TBA or forward commitment purchase obligations will be earmarked on the Fund’s books. There is no guarantee, however, that such earmarking will be successful in reducing or eliminating the leveraging effect of such transactions or the risks associated with leverage.

A TBA transaction involves a commitment to purchase securities sold for a fixed price where the underlying securities are announced at a future date. The seller does not specify the particular securities to be delivered. Instead, the Fund agrees to accept any security that meets specified terms. For example, in a TBA mortgage-backed security transaction, the Fund and the seller would agree upon the issuer, interest rate and terms of the underlying mortgages. The seller would not identify the specific underlying mortgages until it issues the security. For this reason, in a TBA transaction, the Fund commits to purchase securities for which all specific information is not yet known at the time of the trade, particularly the exact face amount in forward commitment mortgage-backed securities transactions. The purchaser in a TBA transaction generally is subject to increased market risk and interest rate risk because the delivered securities may be less favorable than anticipated by the purchaser. The Fund may also enter into a forward commitment to sell securities it owns. The use of forward commitments enables the Fund to hedge against anticipated changes in interest rates and prices. In a forward sale, the Fund does not participate in gains or losses on the security occurring after the commitment date. Forward commitments to sell securities also involve a risk of loss if the seller fails to take delivery after the value of the securities has declined. Forward commitment transactions involve additional risks similar to those associated with investments in options and futures contracts.

Recently finalized rules of the Financial Industry Regulatory Authority, Inc. (“FINRA”) impose mandatory margin requirements for “Covered Agency Transactions,” which include TBA Transactions, certain transactions in pass-through mortgage-backed securities or small-business administration-backed asset-backed securities and transactions in collateralized mortgage obligations, in each case where such transactions have delayed contractual settlement dates of a specified period. There are limited exceptions to these margin requirements. Covered Agency Transactions historically have not been required to be collateralized. The collateralization of Covered Agency Transactions is intended to mitigate counterparty credit risk between trade and settlement, but could increase the cost of such transactions and impose added operational complexity.

Zero Coupon Securities

The Fund may invest in zero coupon securities. Zero coupon securities are notes, bonds and debentures that: (1) do not pay current interest and are issued at a substantial discount from par value; (2) have been stripped of their unmatured interest coupons and receipts; or (3) pay no interest until a stated date one or more years into the future. These securities also include certificates representing interests in such stripped coupons and receipts. Generally, changes in interest rates will have a greater impact on the market value of a zero coupon security than on the market value of the comparable securities that pay interest periodically during the life of the instrument. In the case of any zero-coupon debt obligations with a fixed maturity date of more than one year from the date of issuance that are treated as issued originally at a discount, the Fund (or Underlying Fund, as applicable) will be required to accrue original issue discount (“OID”) for U.S. federal income tax purposes and may as a result be required to pay out as an income distribution an amount which is greater than the total amount of cash interest the Fund actually received. To generate sufficient cash to make the requisite distributions to maintain its qualification for treatment as a RIC, the Fund (or Underlying Fund, as applicable) may be required to sell investments, including at a time when it may not be advantageous to do so.

Privately-issued stripped securities are not themselves guaranteed by the U.S. Government, but the future payment of principal or interest on U.S. Treasury obligations which they represent is so guaranteed.

Asset Segregation and Coverage

The Fund may be required to earmark or otherwise segregate liquid assets in respect of its obligations under derivatives transactions that involve contractual obligations to pay in the future, or the Fund may engage in other measures to “cover” its obligations with respect to such transactions. The amounts that are earmarked or otherwise segregated may be based on the notional value of the derivative 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. In certain circumstances, the Fund may enter into an offsetting position rather than earmarking or segregating liquid assets. The Fund may modify its asset segregation and coverage policies from time to time. Although earmarking or segregating may in certain cases have the effect of limiting the Fund’s ability to engage in derivatives transactions, the extent of any such limitation will depend on a variety of factors, including the method by which the Fund determines the nature and amount of assets to be earmarked or segregated.

Master/Feeder Structure

The Fund may in the future determine to become a “feeder” fund that invests all of its assets in another open-end investment company (a “master fund”) that has substantially similar investment strategies as the Fund. This structure is sometimes called a “master/feeder” structure.

Fundamental Investment Restrictions

The Trust has adopted the following fundamental investments restrictions with respect to the Fund, which may not be changed without the affirmative vote of a “majority of the outstanding voting securities” of the Fund, which is defined in the 1940 Act to mean the affirmative vote of the lesser of (1) more than 50% of the outstanding shares of the Fund and (2) 67% or more of the shares present at a meeting if more than 50% of the outstanding shares are present at the meeting in person or by proxy.

For purposes of the above investment limitation number 6, in the case of a tax-exempt bond issued by a non-governmental user, where the tax-exempt bond is backed only by the assets and revenues of the non-governmental user, then such non-governmental user would be deemed to be the sole issuer. All percentage limitations (except the limitation to borrowings) on investments will apply at the time of the making of an investment and shall not be considered violated unless an excess or deficiency occurs or exists immediately after and as a result of such investment. Except for the investment restrictions expressly identified as fundamental, or to the extent designated as such in the Prospectus with respect to the Fund, the other investment policies described in this SAI or in the Prospectus are not fundamental and may be changed by approval of the Trustees without shareholder approval.
