INVESTMENT POLICIES

The Fund may invest in the following types of investments, consistent with its investment strategies and objective. Please see the Fund’s Prospectus for additional information regarding its principal investment strategies.

ASSET-BACKED AND COMMERCIAL MORTGAGE-BACKED SECURITIES

The Fund may invest in asset-backed and commercial mortgage-backed securities. Asset-backed securities are securities backed by installment contracts, credit-card receivables or other assets. Commercial mortgage-backed securities are securities backed by commercial real estate properties. Both asset-backed and commercial mortgage-backed securities represent interests in “pools” of assets in which payments of both interest and principal on the securities are made on a regular basis. The payments are, in effect, “passed through” to the holder of the securities (net of any fees paid to the issuer or guarantor of the securities). The average life of asset-backed and commercial mortgage-backed securities varies with the maturities of the underlying instruments and, as a result of prepayments, can often be less than the original maturity of the assets underlying the securities. For this and other reasons, an asset-backed and commercial mortgage-backed security’s stated maturity may be shortened, and the security’s total return may be difficult to predict precisely.

BONDS

The Fund may invest 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).

Table of Contents

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.

BUILD AMERICA BONDS

The Fund may invest in Build America Bonds. Build America Bonds offer an alternative form of financing to state and local governments whose primary means for accessing the capital markets has historically been through the issuance of tax-free municipal bonds. The Build America Bond program allows state and local governments to issue taxable bonds for capital projects and to receive a direct federal subsidy payment from the Treasury Department for a portion of their borrowing costs. There are two general types of Build America Bonds. The first type of Build America Bond provides a Federal subsidy through Federal tax credits to investors in the bonds in an amount equal to 35 percent of the total coupon interest payable by the issuer on taxable governmental bonds (net of the tax credit), which represents a Federal subsidy to the state or local governmental issuer equal to approximately 25 percent of the total return to the investor (including the coupon interest paid by the issuer and the tax credit). The second type of Build America Bond provides a Federal subsidy through a refundable tax credit paid to state or local governmental issuers by the Treasury Department and the Internal Revenue Service (the “IRS”) in an amount equal to 35 percent (or 45 percent in the case of Recovery Zone Economic Development Bonds) of the total coupon interest payable to investors in these taxable bonds.

Issuance of Build America Bonds ceased on December 31, 2010. The Build America Bonds outstanding continue to be eligible for the federal interest rate subsidy, which continues for the life of the Build America Bonds; however, no bonds issued following expiration of the Build America Bond program are eligible for the federal tax subsidy.

COMMERCIAL PAPER

The Fund may invest in commercial paper. Commercial paper consists of short-term, promissory notes issued by banks, corporations and other entities to finance short-term credit needs. These securities generally are discounted but sometimes may be interest bearing.

COMMON STOCKS

The Fund may invest in common stocks. Risks inherent in investing in equity securities include the risk that the financial condition of issuers may become impaired or that the general condition of the stock market may deteriorate (either of which may cause a decrease in the value of the Fund’s portfolio securities and therefore a decrease in the value of Shares of the Fund). Common stocks are susceptible to general stock market fluctuations and to volatile increases and decreases in value as market confidence and perceptions change. These investor perceptions are based on various and unpredictable factors, including expectations regarding government, economic, monetary and fiscal policies; inflation and interest rates; economic expansion or contraction; and global or regional political, economic or banking crises.

CONCENTRATION

The Fund’s investments will generally be concentrated in a particular industry or group of industries to the extent that the Fund’s underlying Index is concentrated in a particular industry or group of industries. The securities of issuers in particular industries may dominate the benchmark Index of the Fund and consequently the Fund’s investment portfolio. This may adversely affect the Fund’s performance or subject its Shares to greater price volatility than that experienced by less concentrated investment companies. The Trust’s general policy is to exclude securities of the U.S. government and its agencies or instrumentalities when measuring industry concentration.

Table of Contents

In pursuing its objective, the Fund may hold the securities of a single issuer in an amount exceeding 10% of the market value of the outstanding securities of the issuer, subject to restrictions imposed by the Internal Revenue Code. In particular, as the Fund’s size grows and its assets increase, it will be more likely to hold more than 10% of the securities of a single issuer if the issuer has a relatively small public float as compared to other components in its benchmark Index.

CONVERTIBLE SECURITIES

The Fund may invest in convertible securities. Convertible securities are bonds, debentures, notes, preferred stocks or other securities that may be converted or exchanged (by the holder or by the issuer) into shares of the underlying common stock (or cash or securities of equivalent value) at a stated exchange ratio. A convertible security may also be called for redemption or conversion by the issuer after a particular date and under certain circumstances (including a specified price) established upon issue. If a convertible security held by the Fund is called for redemption or conversion, the Fund could be required to tender it for redemption, convert it into the underlying common stock, or sell it to a third party.

Convertible securities generally have less potential for gain or loss than common stocks. Convertible securities generally provide yields higher than the underlying common stocks, but generally lower than comparable non-convertible securities. Because of this higher yield, convertible securities generally sell at a price above their “conversion value,” which is the current market value of the stock to be received upon conversion. The difference between this conversion value and the price of convertible securities will vary over time depending on changes in the value of the underlying common stocks and interest rates. When the underlying common stocks decline in value, convertible securities will tend not to decline to the same extent because of the interest or dividend payments and the repayment of principal at maturity for certain types of convertible securities. However, securities that are convertible other than at the option of the holder generally do not limit the potential for loss to the same extent as securities convertible at the option of the holder. When the underlying common stocks rise in value, the value of convertible securities may also be expected to increase. At the same time, however, the difference between the market value of convertible securities and their conversion value will narrow, which means that the value of convertible securities will generally not increase to the same extent as the value of the underlying common stocks. Because convertible securities may also be interest-rate sensitive, their value may increase as interest rates fall and decrease as interest rates rise. Convertible securities are also subject to credit risk, and are often lower-quality securities.

DIVERSIFICATION STATUS

The Fund is classified as a non-diversified investment company under the 1940 Act. A “non-diversified” classification means that the Fund is not limited by the 1940 Act with regard to the percentage of its assets that may be invested in the securities of a single issuer. This means that the Fund may invest a greater portion of its assets in the securities of a single issuer than a diversified fund. The securities of a particular issuer may constitute a greater portion of the Index and, therefore, the securities may constitute a greater portion of the Fund’s portfolio. This may have an adverse effect on the Fund’s performance or subject the Fund’s Shares to greater price volatility than more diversified investment companies.

Although the Fund is non-diversified for purposes of the 1940 Act, the Fund intends to maintain the required level of diversification and otherwise conduct its operations so as to qualify as a “regulated investment company” for purposes of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”), and to relieve the Fund of any liability for federal income tax to the extent that its earnings are distributed to shareholders. Compliance with the diversification requirements of the Internal Revenue Code may limit the investment flexibility of the Fund and may make it less likely that the Fund will meet its investment objective.

FUTURES CONTRACTS, OPTIONS AND SWAP AGREEMENTS

The Fund may invest up to 20% of its assets in derivatives, including exchange-traded futures on Treasuries or Eurodollars, U.S. exchange-traded or OTC put and call options contracts and exchange-traded or OTC swap agreements (including interest rate swaps, total return swaps, excess return swaps, and credit default swaps). The Fund will segregate cash and/or appropriate liquid assets if required to do so by SEC or Commodity Futures Trading Commission (“CFTC”) regulation or interpretation.

Futures contracts generally provide for the future sale by one party and purchase by another party of a specified commodity or security at a specified future time and at a specified price. Index futures contracts are settled daily with a payment by one party to the other of a cash amount based on the difference between the level of the index specified in the contract from one day to the next. Futures contracts are standardized as to maturity date and underlying instrument and are traded on futures exchanges.

The Fund is required to make a good faith margin deposit in cash or U.S. government securities with a broker or custodian to initiate and maintain open positions in futures contracts. A margin deposit is intended to assure completion of the contract (delivery or acceptance of the underlying commodity or payment of the cash settlement amount) if it is not terminated prior to the specified delivery date. Brokers may establish deposit requirements which are higher than the exchange minimums. Futures contracts are customarily purchased and sold on margin deposits which may range upward from less than 5% of the value of the contract being traded.

Table of Contents

After a futures contract position is opened, the value of the contract is marked to market daily. If the futures contract price changes to the extent that the margin on deposit does not satisfy margin requirements, payment of additional “variation” margin will be required. Conversely, change in the contract value may reduce the required margin, resulting in a repayment of excess margin to the contract holder. Variation margin payments are made to and from the futures broker for as long as the contract remains open. In such case, the Fund would expect to earn interest income on its margin deposits. Closing out an open futures position is done by taking an opposite position (“buying” a contract which has previously been “sold,” or “selling” a contract previously “purchased”) in an identical contract to terminate the position. Brokerage commissions are incurred when a futures contract position is opened or closed.

The Fund may purchase and sell put and call options. Such options may relate to particular securities and may or may not be listed on a national securities exchange and issued by the Options Clearing Corporation. Options trading is a highly specialized activity that entails greater than ordinary investment risk. Options on particular securities may be more volatile than the underlying securities, and therefore, on a percentage basis, an investment in options may be subject to greater fluctuation than an investment in the underlying securities themselves.

The Fund intends to use futures and options in accordance with Rule 4.5 of the Commodity Exchange Act (“CEA”). The Fund may use exchange-traded futures and options, together with positions in cash and money market instruments, to simulate full investment in its underlying Index. Exchange-traded futures and options contracts may not be currently available for an Index. Under such circumstances, the Adviser may seek to utilize other instruments that it believes to be correlated to the applicable Index components or a subset of the components. The Trust, on behalf of the Fund, has filed a notice of eligibility for exclusion from the definition of the term “commodity pool operator” in accordance with Rule 4.5 so that the Fund is not subject to registration or regulation as a commodity pool operator under the CEA.

Restrictions on the Use of Futures and Options. In connection with its management of the Fund, the Adviser has claimed an exclusion from registration as a commodity trading advisor under the CEA and, therefore, is not subject to the registration and regulatory requirements of the CEA. The Fund reserves the right to engage in transactions involving futures and options thereon to the extent allowed by the CFTC regulations in effect from time to time and in accordance with the Fund’s policies. The Fund would take steps to prevent its futures positions from “leveraging” its securities holdings. When it has a long futures position, it will maintain with its custodian bank, cash or equivalents. When it has a short futures position, it will maintain with its custodian bank assets substantially identical to those underlying the contract or cash and equivalents (or a combination of the foregoing) having a value equal to the net obligation of the Fund under the contract (less the value of any margin deposits in connection with the position).

Swap Agreements. The Fund may enter into swap agreements, including interest rate, index and total return swap agreements. Swap agreements are contracts between parties in which one party agrees to make periodic payments to the other party based on the change in market value or level of a specified rate, index or asset. In return, the other party agrees to make payments to the first party based on the return of a different specified rate, index or asset. Swap agreements will usually be done on a net basis, i.e. , where the two parties make net payments with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each swap is accrued on a daily basis and an amount of cash or equivalents having an aggregate value at least equal to the accrued excess is maintained by the Fund.

In the case of a credit default swap (“CDS”), the contract gives one party (the buyer) the right to recoup the economic value of a decline in the value of debt securities of the reference issuer if the credit event (a downgrade or default) occurs. This value is obtained by delivering a debt security of the reference issuer to the party in return for a previously agreed payment from the other party (frequently, the par value of the debt security). As the seller of a CDS contract, the Fund would be required to pay the par (or other agreed upon) value of a referenced debt obligation to the counterparty in the event of a default or other credit event by the reference issuer, such as a U.S. or foreign corporate issuer, with respect to debt obligations. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would be subject to investment exposure on the notional amount of the swap.

CDSs may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of a reference obligation. The Fund will segregate assets necessary to meet any accrued payment obligations when it is the buyer of CDSs. In cases where the Fund is a seller of a CDS, if the CDS is physically settled, the Fund will be required to segregate the full notional amount of the CDS. Such segregation will not limit the Fund’s exposure to loss. CDS agreements involve greater risks than if the Fund had invested in the reference obligation directly since, in addition to general market risks, illiquidity risk associated with a particular issuer, and credit risk, each of which will be similar in either case, CDSs are subject to the risk of illiquidity within the CDS market on the whole, as well as counterparty risk. The Fund will enter into CDS agreements only with counterparties that meet certain standards of creditworthiness. The Fund will only enter into CDSs for purposes of better tracking the performance of its Index.

FUTURE DEVELOPMENTS

The Fund may take advantage of opportunities in the area of options and futures contracts, options on futures contracts, warrants, swaps and any other investments which are not presently contemplated for use by the Fund or which are not currently available but which may be developed, to the extent such opportunities are both consistent with the Fund’s investment objective and legally permissible for the Fund. Before entering into such transactions or making any such investment, the Fund will provide appropriate disclosure.

HIGH YIELD SECURITIES

The Fund may invest a portion of its assets in high yield securities. 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 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.

INFLATION-PROTECTED OBLIGATIONS

The fund may invest in inflation-protected obligations. An inflation-protected debt security is a type of security issued by a government that is designed to provide inflation protection to investors. Inflation-protected debt securities are income-generating instruments whose interest and principal payments are adjusted for inflation—a sustained increase in prices that erodes the purchasing power of money. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, such as the Consumer Price Index. A fixed coupon rate is applied to the inflation-adjusted principal so that as inflation rises or falls, both the principal value and the interest payments will increase or decrease. This can provide investors with a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds.

INVESTMENT COMPANIES

The Fund may invest in the securities of other investment companies, including affiliated funds and money market funds, subject to applicable limitations under Section 12(d)(1) of the 1940 Act. Pursuant to Section 12(d)(1), the Fund may invest in the securities of another investment company (the “acquired company”) provided that the Fund, immediately after such purchase or acquisition, does not own in the aggregate: (i) more than 3% of the total outstanding voting stock of the acquired company; (ii) securities issued by the acquired company having an aggregate value in excess of 5% of the value of the total assets of the Fund; or (iii) securities issued by the acquired company and all other investment companies (other than Treasury stock of the Fund) having an aggregate value in excess of 10% of the value of the total assets of the Fund. To the extent allowed by law, regulation, the Fund’s investment restrictions and the Trust’s exemptive relief, the Fund may invest its assets in securities of investment companies that are affiliated funds and/or money market funds in excess of the limits discussed above.

Table of Contents

If the Fund invests in and, thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.

LENDING PORTFOLIO 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 one quarter (25%) of the value of its total 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. 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 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 short-term instruments either directly on behalf of the Fund or through one or more joint accounts or money market funds, which may include those managed by the Adviser.

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 of Trustees of the Trust (the “Board”) who administer the lending program for the Fund in accordance with guidelines approved by the Board. In such capacity, the lending agent causes the delivery of loaned securities from the Fund to borrowers, arranges for the return of loaned securities to the Fund at the termination of a loan, requests deposit of collateral, monitors the daily value of the loaned securities and collateral, requests that borrowers add to the collateral when required by the loan agreements, and provides recordkeeping and accounting services necessary for the operation of the program. 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) and 12(d)(1) under the 1940 Act to serve as the lending agent for affiliated investment companies such as the Trust and to invest the cash collateral received from loan transactions to be invested in an affiliated cash collateral fund.

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. 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.

LEVERAGING

While the Fund does not anticipate doing so, the Fund may borrow money in an amount greater than 5% of the value of the Fund’s total assets. However, under normal circumstances, the Fund will not borrow money from a bank in an amount greater than 10% of the value of the Fund’s total assets. Borrowing for investment purposes is one form of leverage. Leveraging investments, by purchasing securities with borrowed money, is a speculative technique that increases investment risk, but also increases investment opportunity. Because substantially all of the Fund’s assets will fluctuate in value, whereas the interest obligations on borrowings may be fixed, the NAV of the Fund will increase more when the Fund’s portfolio assets increase in value and decrease more when the Fund’s portfolio assets decrease in value than would otherwise be the case. Moreover, interest costs on borrowings may fluctuate with changing market rates of interest and may partially offset or exceed the returns on the borrowed funds.

MUNICIPAL SECURITIES

Municipal securities are securities issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. Municipal securities share the attributes of debt/fixed income securities in general, but are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. The municipal securities which the Fund may purchase include general obligation bonds and limited obligation bonds (or revenue bonds), including industrial development bonds issued pursuant to former federal tax law. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer’s general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Tax-exempt industrial development bonds generally are also revenue bonds and thus are not payable from the issuer’s general revenues. The credit and quality of industrial development bonds are usually related to the credit of the corporate user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the corporate user (and/or any guarantor).

Some longer-term municipal securities give the investor the right to “put” or sell the security at par (face value) within a specified number of days following the investor’s request—usually one to seven days. This demand feature enhances a security’s liquidity by shortening its effective maturity and enables it to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, the Fund would hold the longer-term security, which could experience substantially more volatility.

The market for municipal bonds may be less liquid than for taxable bonds. This means that it may be harder to buy and sell municipal securities, especially on short notice, than non-municipal securities. There may also be less information available on the financial condition of issuers of municipal securities than for public corporations. This means that it may be harder to buy and sell municipal securities, especially on short notice, and municipal securities may be more difficult for the Fund to value accurately than securities of public corporations. If the Fund invests a significant portion of its portfolio in municipal securities, the Fund may have greater exposure to liquidity risk than a fund that invests in non-municipal securities. In addition, the municipal securities market is generally characterized as a buy and hold investment strategy. As a result, the accessibility of municipal securities in the market is generally greater closer to the original date of issue of the securities and lessens as the securities move further away from such issuance date.

Municipal securities are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate more with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues.

Prices and yields on municipal securities are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal security market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal securities may not be as extensive as that which is made available by corporations whose securities are publicly traded. As a result, municipal securities may be more difficult to value than securities of public corporations.

Obligations of issuers of municipal securities are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. In addition, municipal securities are subject to the risk that their tax treatment could be changed by Congress or state legislatures, thereby affecting the value of outstanding municipal securities. There is also the possibility that as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal securities may be materially affected or their obligations may be found to be invalid or unenforceable. Such litigation or conditions may from time to time have the effect of introducing uncertainties in the market for municipal securities or certain segments thereof, or of materially affecting the credit risk with respect to particular bonds. Adverse economic, business, legal or political developments might affect all or a substantial portion of the Fund’s municipal securities in the same manner.

Municipal Insurance. A municipal security may be covered by insurance that guarantees the bond’s scheduled payment of interest and repayment of principal. This type of insurance may be obtained by either (i) the issuer at the time the bond is issued (primary market insurance), or (ii) another party after the bond has been issued (secondary market insurance).

Both primary and secondary market insurance guarantee timely and scheduled repayment of all principal and payment of all interest on a municipal security in the event of default by the issuer, and cover a municipal security to its maturity, enhancing its credit quality and value.

Municipal security insurance does not insure against market fluctuations or fluctuations in the Fund’s share price. In addition, a municipal security insurance policy will not cover: (i) repayment of a municipal security before maturity (redemption), (ii) prepayment or payment of an acceleration premium (except for a mandatory sinking fund redemption) or any other provision of a bond indenture that advances the maturity of the bond, or (iii) nonpayment of principal or interest caused by negligence or bankruptcy of the paying agent. A mandatory sinking fund redemption may be a provision of a municipal security issue whereby part of the municipal security issue may be retired before maturity.

Table of Contents

Because a significant portion of the municipal securities issued and outstanding is insured by a small number of insurance companies, an event involving one or more of these insurance companies could have a significant adverse effect on the value of the securities insured by that insurance company and on the municipal markets as a whole.

Municipal Market Disruption Risk. The value of municipal securities may be affected by uncertainties in the municipal market related to legislation or litigation involving the taxation of municipal securities or the rights of municipal securities holders in the event of a bankruptcy. Proposals to restrict or eliminate the federal income tax exemption for interest on municipal securities are introduced before Congress from time to time. Proposals also may be introduced before state legislatures that would affect the state tax treatment of a municipal fund’s distributions. If such proposals were enacted, the availability of municipal securities and the value of a municipal fund’s holdings would be affected. Municipal bankruptcies are relatively rare, and certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear and remain untested. Further, the application of state law to municipal issuers could produce varying results among the states or among municipal securities issuers within a state. These legal uncertainties could affect the municipal securities market generally, certain specific segments of the market, or the relative credit quality of particular securities. Any of these effects could have a significant impact on the prices of some or all of the municipal securities held by the Fund.

OTHER SHORT-TERM INSTRUMENTS

In addition to repurchase agreements, the Fund may invest in short-term instruments, including money market instruments, (including money market funds advised by the Adviser), cash and cash equivalents, on an ongoing basis to provide liquidity or for other reasons. Money market instruments are generally short-term investments that may include but are not limited to: (i) shares of money market funds (including those advised by the Adviser); (ii) obligations issued or guaranteed by the U.S. government, its agencies or instrumentalities (including government-sponsored enterprises); (iii) negotiable certificates of deposit (“CDs”), bankers’ acceptances, fixed time deposits and other obligations of U.S. and foreign banks (including foreign branches) and similar institutions; (iv) commercial paper rated at the date of purchase “Prime-1” by Moody’s Investors Service (“Moody’s”) or “A-1” by Standard & Poor’s (“S&P”), or if unrated, of comparable quality as determined by the Adviser; (v) non-convertible corporate debt securities ( e.g. , bonds and debentures) with remaining maturities at the date of purchase of not more than 397 days and that satisfy the rating requirements set forth in Rule 2a-7 under the 1940 Act; and (vi) short-term U.S. dollar-denominated obligations of foreign banks (including U.S. branches) that, in the opinion of the Adviser, are of comparable quality to obligations of U.S. banks which may be purchased by the Fund. Any of these instruments may be purchased on a current or a forward-settled basis. Money market instruments also include shares of money market funds. Time deposits are non-negotiable deposits maintained in banking institutions for specified periods of time at stated interest rates. Bankers’ acceptances are time drafts drawn on commercial banks by borrowers, usually in connection with international transactions.

PREFERRED SECURITIES

The Fund may invest in preferred securities. Preferred securities pay fixed or adjustable rate dividends to investors, and have “preference” over common stock in the payment of dividends and the liquidation of a company’s assets. This means that a company must pay dividends on preferred stock before paying any dividends on its common stock. In order to be payable, distributions on preferred securities must be declared by the issuer’s board of directors. Income payments on typical preferred securities currently outstanding are cumulative, causing dividends and distributions to accrue even if not declared by the board of directors or otherwise made payable. There is no assurance that dividends or distributions on the preferred securities in which the Fund invests will be declared or otherwise made payable.

The market value of preferred securities may be affected by favorable and unfavorable changes impacting companies in the utilities and financial services sectors, which are prominent issuers of preferred securities, and by actual and anticipated changes in tax laws.

Because the claim on an issuer’s earnings represented by preferred securities may become onerous when interest rates fall below the rate payable on such securities, the issuer may redeem the securities. Thus, in declining interest rate environments in particular, the Fund’s holdings of higher rate-paying fixed rate preferred securities may be reduced and the Fund would be unable to acquire securities paying comparable rates with the redemption proceeds.

REPURCHASE AGREEMENTS

The Fund may invest in repurchase agreements with commercial banks, brokers or dealers to generate income from its excess cash balances and to invest securities lending cash collateral. A repurchase agreement is an agreement under which the Fund acquires a financial instrument ( e.g. , a security issued by the U.S. government or an agency thereof, a banker’s acceptance or a certificate of deposit) from a seller, subject to resale to the seller at an agreed upon price and date (normally, the next Business Day – as defined below). A repurchase agreement may be considered a loan collateralized by securities. The resale price reflects an agreed upon interest rate effective for the period the instrument is held by the Fund and is unrelated to the interest rate on the underlying instrument.

10

Table of Contents

In these repurchase agreement transactions, the securities acquired by the Fund (including accrued interest earned thereon) must have a total value in excess of the value of the repurchase agreement and are held by the Custodian until repurchased. No more than an aggregate of 15% of the Fund’s net assets will be invested in illiquid securities, including repurchase agreements having maturities longer than seven days and securities subject to legal or contractual restrictions on resale, or for which there are no readily available market quotations.

The use of repurchase agreements involves certain risks. For example, if the other party to the agreement defaults on its obligation to repurchase the underlying security at a time when the value of the security has declined, the Fund may incur a loss upon disposition of the security. If the other party to the agreement becomes insolvent and subject to liquidation or reorganization under the U.S. Bankruptcy Code or other laws, a court may determine that the underlying security is collateral for a loan by the Fund not within the control of the Fund and, therefore, the Fund may not be able to substantiate its interest in the underlying security and may be deemed an unsecured creditor of the other party to the agreement.

REVERSE REPURCHASE AGREEMENTS

The Fund may enter into reverse repurchase agreements, which involve the sale of securities with an agreement to repurchase the securities at an agreed-upon price, date and interest payment and have the characteristics of borrowing. The securities purchased with the funds obtained from the agreement and securities collateralizing the agreement will have maturity dates no later than the repayment date. Generally the effect of such transactions is that the Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while in many cases the Fund is able to keep some of the interest income associated with those securities. Such transactions are only advantageous if the Fund has an opportunity to earn a greater rate of interest on the cash derived from these transactions than the interest cost of obtaining the same amount of cash. Opportunities to realize earnings from the use of the proceeds equal to or greater than the interest required to be paid may not always be available and the Fund intends to use the reverse repurchase technique only when the Adviser believes it will be advantageous to the Fund. The use of reverse repurchase agreements may exaggerate any interim increase or decrease in the value of the Fund’s assets. The Fund’s exposure to reverse repurchase agreements will be covered by securities having a value equal to or greater than such commitments. Under the 1940 Act, reverse repurchase agreements are considered borrowings. Although there is no percentage limit on Fund assets that can be used in connection with reverse repurchase agreements, the Fund does not expect to engage, under normal circumstances, in reverse repurchase agreements with respect to more than 10% of its total assets.

U.S. GOVERNMENT OBLIGATIONS

The Fund may invest a portion of its assets in U.S. Government obligations. U.S. Government obligations are a type of bond. U.S. Government obligations include securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies or instrumentalities.

One type of U.S. Government obligation, U.S. Treasury obligations, are backed by the full faith and credit of the U.S. Treasury and differ only in their interest rates, maturities, and times of issuance. U.S. Treasury bills have initial maturities of one-year or less; U.S. Treasury notes have initial maturities of one to ten years; and U.S. Treasury bonds generally have initial maturities of greater than ten years.

Other U.S. Government obligations are issued or guaranteed by agencies or instrumentalities of the U.S. Government including, but not limited to, Federal National Mortgage Association (“Fannie Mae”), the Government National Mortgage Association (“Ginnie Mae”), the Small Business Administration, the Federal Farm Credit Administration, the Federal Home Loan Mortgage Corporation (“Freddie Mac”), the Federal Home Loan Banks (“FHLB”), Banks for Cooperatives (including the Central Bank for Cooperatives), the Federal Land Banks, the Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation (Farmer Mac). Some obligations issued or guaranteed by U.S. Government agencies and instrumentalities, including, for example, Ginnie Mae pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by Fannie Mae, are supported by the discretionary authority of the U.S. Government to purchase certain obligations of the federal agency, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury. While the U.S. Government provides financial support to such U.S. Government-sponsored federal agencies, no assurance can be given that the U.S. Government will always do so, since the U.S. Government is not so obligated by law.

In September 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. Under the terms of the takeover, the U.S. Treasury agreed to acquire $1 billion of senior preferred stock of each instrumentality and obtained warrants for the purchase of common stock of each instrumentality. Under these Senior Preferred Stock Purchase Agreements (“SPAs”), the U.S. Treasury has pledged to provide a limited amount of capital per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their

11

Table of Contents

assets. In May 2009, the U.S. Treasury increased its maximum commitment to each instrumentality under the SPAs from $100 billion to $200 billion per instrumentality. In December 2009, the U.S. Treasury amended the SPAs to provide Fannie Mae and Freddie Mac with some additional flexibility to meet the requirement to reduce their mortgage portfolios. Also in December 2009, the U.S. Treasury further amended the SPAs to allow the cap on the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in Fannie Mae’s and Freddie Mac’s net worth through the end of 2012. On August 17, 2012, the U.S. Treasury announced that it was again amending the Agreement to terminate the requirement that Fannie Mae and Freddie Mac each pay a 10% dividend annually on all amounts received under the funding commitment. Instead, they will transfer to the U.S. Treasury on a quarterly basis all profits earned during a quarter that exceed a capital reserve amount of $3 billion. The U.S. Treasury stated that the purpose of the change was to wind down Freddie Mac and Fannie Mae and to benefit taxpayers. At the start of 2013, the unlimited support the U.S. Treasury extended to the two companies expired—Fannie Mae’s bailout is now capped at $125 billion and Freddie Mac has a limit of $149 billion. In August 2013, President Obama announced his proposal to shut down Freddie Mac and Fannie Mae as part of a plan to overhaul the U.S.’s mortgage finance system. Until further action is taken, the actions of the U.S. Treasury are intended to ensure that Fannie Mae and Freddie Mac maintain a positive net worth and meet their financial obligations, preventing mandatory triggering of receivership. No assurance can be given that the U.S. Treasury initiatives will be successful.

SPECIAL CONSIDERATIONS AND RISKS

A discussion of the risks associated with an investment in the Fund is contained in the Prospectus. The discussion below supplements, and should be read in conjunction with, the Prospectus.

GENERAL

Investment in the Fund should be made with an understanding that the value of the Fund’s portfolio securities may fluctuate in accordance with changes in the financial condition of the issuers of the portfolio securities, the value of securities generally and other factors.

An investment in the Fund should also be made with an understanding of the risks inherent in an investment in securities, including the risk that the financial condition of issuers may become impaired or that the general condition of the securities markets may deteriorate (either of which may cause a decrease in the value of the portfolio securities and thus in the value of Shares). Securities are susceptible to general market fluctuations and to volatile increases and decreases in value as market confidence in and perceptions of their issuers change. These investor perceptions are based on various and unpredictable factors including expectations regarding government, economic, monetary and fiscal policies, inflation and interest rates, economic expansion or contraction, and global or regional political, economic and banking crises.

Holders of common stocks incur more risk than holders of preferred stocks and debt obligations because common stockholders, as owners of the issuer, have generally inferior rights to receive payments from the issuer in comparison with the rights of creditors of, or holders of debt obligations or preferred stocks issued by, the issuer. Further, unlike debt securities which typically have a stated principal amount payable at maturity (whose value, however, will be subject to market fluctuations prior thereto), or preferred stocks which typically have a liquidation preference and which may have stated optional or mandatory redemption provisions, common stocks have neither a fixed principal amount nor a maturity. Common stock values are subject to market fluctuations as long as the common stock remains outstanding.

The principal trading market for some of the securities in the Index may be in the over-the-counter market. The existence of a liquid trading market for certain securities may depend on whether dealers will make a market in such securities. There can be no assurance that a market will be made or maintained or that any such market will be or remain liquid. The price at which securities may be sold and the value of the Fund’s Shares will be adversely affected if trading markets for the Fund’s portfolio securities are limited or absent or if bid/ask spreads are wide.

CONFLICTS OF INTEREST RISK

An investment in the Fund may be subject to a number of actual or potential conflicts of interest. For example, the Adviser or its affiliates may provide services to the Fund, such as securities lending agency services, custodial, administrative, bookkeeping, and accounting services, transfer agency and shareholder servicing, securities brokerage services, and other services for which the Fund would compensate the Adviser and/or such affiliates. The Fund may invest in other pooled investment vehicles sponsored, managed, or otherwise affiliated with the Adviser. There is no assurance that the rates at which the Fund pays fees or expenses to the Adviser or its affiliates, or the terms on which it enters into transactions with the Adviser or its affiliates, will be the most favorable available in the market generally or as favorable as the rates the Adviser makes available to other clients. Because of its financial interest, the Adviser may have an incentive to enter into transactions or arrangements on behalf of the Fund with itself or its affiliates in circumstances where it might not have done so in the absence of that interest.

CONTINUOUS OFFERING

The method by which Creation Units of Shares are created and traded may raise certain issues under applicable securities laws. Because new Creation Units of Shares are issued and sold by the Trust on an ongoing basis, at any point a “distribution,” as such term is used in the Securities Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the Securities Act.

For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares, and sells such Shares directly to customers, or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether one is an underwriter for purposes of the Securities Act must take into account all the facts and circumstances pertaining to the activities of the broker-dealer or its client in the particular case, and the examples mentioned above should not be considered a complete description of all the activities that could lead to a categorization as an underwriter.

Broker-dealer firms should also note that dealers who are not “underwriters” but are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the Securities Act is not available in respect of such transactions as a result of Section 24(d) of the 1940 Act. Firms that incur a prospectus-delivery obligation with respect to Shares of the Fund are reminded that under Securities Act Rule 153, a prospectus-delivery obligation under Section 5(b)(2) of the Securities Act owed to an exchange member in connection with a sale on the Exchange is satisfied by the fact that the Fund’s Prospectus is available at the Exchange upon request. The prospectus delivery mechanism provided in Rule 153 is only available with respect to transactions on an exchange.

FUTURES AND OPTIONS TRANSACTIONS

There can be no assurance that a liquid secondary market will exist for any particular futures contract or option at any specific time. Thus, it may not be possible to close a futures or options position. In the event of adverse price movements, the Fund would continue to be required to make daily cash payments to maintain its required margin. In such situations, if the Fund has insufficient cash, it may have to sell portfolio securities to meet daily margin requirements at a time when it may be disadvantageous to do so. In addition, the Fund may be required to make delivery of the instruments underlying futures contracts it has sold.

The Fund will minimize the risk that it will be unable to close out a futures or options contract by only entering into futures and options for which there appears to be a liquid secondary market.

The risk of loss in trading futures contracts or uncovered call options in some strategies ( e.g. , selling uncovered index futures contracts) is potentially unlimited. The Fund does not plan to use futures and options contracts, when available, in this manner. The risk of a futures position may still be large as traditionally measured due to the low margin deposits required. In many cases, a relatively small price movement in a futures contract may result in immediate and substantial loss or gain to the investor relative to the size of a required margin deposit. The Fund, however, may utilize futures and options contracts in a manner designed to limit its risk exposure to that which is comparable to what it would have incurred through direct investment in securities.

Utilization of futures transactions by the Fund involves the risk of imperfect or even negative correlation to its benchmark Index if the index underlying the futures contracts differs from the benchmark Index or if the futures contracts do not track the benchmark Index as expected. There is also the risk of loss by the Fund of margin deposits in the event of bankruptcy of a broker with whom the Fund has an open position in the futures contract or option.

Certain financial futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of a trading session. Once the daily limit has been reached in a particular type of contract, no trades may be made on that day at a price beyond that limit. The daily limit governs only price movement during a particular trading day and therefore does not limit potential losses, because the limit may prevent the liquidation of unfavorable positions. Futures contract prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and subjecting some futures traders to substantial losses.

RISKS OF SWAP AGREEMENTS

Swap agreements are subject to the risk that the swap counterparty will default on its obligations. If such a default occurs, the Fund will have contractual remedies pursuant to the agreements related to the transaction, but such remedies may be subject to bankruptcy and insolvency laws which could affect the Fund’s rights as a creditor.

13

Table of Contents

The use of interest-rate and index swaps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. The use of a swap requires an understanding not only of the referenced asset, reference rate or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions. These transactions generally do not involve the delivery of securities or other underlying assets or principal.

The absence of a regulated execution facility or contract market and lack of liquidity for swap transactions has led, in some instances, to difficulties in trading and valuation, especially in the event of market disruptions. [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 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 SSGA 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.

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

Because they are two party contracts that may be subject to contractual restrictions on transferability and termination and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid and subject to the Fund’s limitation on investments in illiquid securities. To the extent that a swap is not liquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses. Like most other investments, swap agreements are subject to the risk that the market value of the instrument will change in a way detrimental to the Fund’s interest.

If the Fund uses a swap as a hedge against, or as a substitute for, a portfolio investment, the Fund will be exposed to the risk that the swap will have or will develop imperfect or no correlation with the portfolio investment. This could cause substantial losses for the Fund. While hedging strategies involving swap instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements in other Fund investments. Many swaps are complex and often valued subjectively.

TAX RISKS

As with any investment, you should consider how your investment in Shares of the Fund will be taxed. The tax information in the Prospectus and this SAI is provided as general information. You should consult your own tax professional about the tax consequences of an investment in Shares of the Fund.

Unless your investment in Shares is made through a tax-exempt entity or tax-advantaged retirement account, such as an individual retirement account, you need to be aware of the possible tax consequences when the Fund makes distributions or you sell Fund Shares.

INVESTMENT RESTRICTIONS

The Trust has adopted the following investment restrictions as fundamental policies with respect to the Fund. These restrictions cannot be changed without the approval of the holders of a majority of the Fund’s outstanding voting securities. For purposes of the 1940 Act, a majority of the outstanding voting securities of the Fund means the vote, at an annual or a special meeting of the security holders of the Trust, of the lesser of (1) 67% or more of the voting securities of the Fund present at such meeting, if the holders of more than 50% of the outstanding voting securities of the Fund are present or represented by proxy, or (2) more than 50% of the outstanding voting securities of the Fund. Except with the approval of a majority of the outstanding voting securities, the Fund may not:

14

Table of Contents

1. Concentrate its investments in securities of issuers in the same industry, except as may be necessary to approximate the composition of the Fund’s underlying Index; ¹

2. Make loans to another person except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund;

3. Issue senior securities or borrow money except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund;

4. Invest directly in real estate unless the real estate is acquired as a result of ownership of securities or other instruments. This restriction shall not preclude the Fund from investing in companies that deal in real estate or in instruments that are backed or secured by real estate;

5. Act as an underwriter of another issuer’s securities, except to the extent the Fund may be deemed to be an underwriter within the meaning of the Securities Act of 1933 in connection with the Fund’s purchase and sale of portfolio securities; or

6. Invest in commodities except as permitted by the 1940 Act or other governing statute, by the Rules thereunder, or by the SEC or other regulatory agency with authority over the Fund.

In addition to the investment restrictions adopted as fundamental policies as set forth above, the Fund observes the following restrictions, which may be changed by the Board without a shareholder vote. The Fund will not:

1. Invest in the securities of a company for the purpose of exercising management or control, provided that the Trust may vote the investment securities owned by the Fund in accordance with its views;

2. Hold illiquid assets in excess of 15% of its net assets. An illiquid asset is any asset which may not be sold or disposed of in the ordinary course of business within seven days at approximately the value at which the Fund has valued the investment;

3. Under normal circumstances, invest less than 80% of its total assets in component securities that comprise its Index;

4. Under normal circumstances, invest less than 80% of its net assets, plus the amount of borrowings for investment purposes, in fixed income securities.

Prior to any change in the Fund’s 80% investment policy, the Fund will provide shareholders with 60 days written notice. The Fund defines the foregoing terms in accordance with the definition of such terms per the Index. If a percentage limitation is adhered to at the time of investment or contract, a later increase or decrease in percentage resulting from any change in value or total or net assets will not result in a violation of such restriction, except that the percentage limitations with respect to the borrowing of money and illiquid securities will be observed continuously. With respect to the limitation on borrowing, in the event that a subsequent change in net assets or other circumstances cause the Fund to exceed its limitation, the Fund will take steps to bring the aggregate amount of borrowing back within the limitations within three days thereafter (not including Sundays and holidays). With respect to the limitation on illiquid securities, in the event that a subsequent change in net assets or other circumstances cause the Fund to exceed its limitation, the Fund will take steps to bring the aggregate amount of illiquid instruments back within the limitations as soon as reasonably practicable.

The 1940 Act currently permits the Fund to loan up to 33 1/3% of its total assets. With respect to borrowing, the 1940 Act presently allows the Fund to: (1) borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 25% of its total assets, (2) borrow money for temporary purposes in an amount not exceeding 5% of the value of the Fund’s total assets at the time of the loan, and (3) enter into reverse repurchase agreements. However, under normal circumstances any borrowings by the Fund will not exceed 10% of the Fund’s total assets. The 1940 Act generally prohibits funds from issuing senior securities, although it does not treat certain transactions as senior securities, such as certain borrowings, short sales, reverse repurchase agreements, firm commitment agreements and standby commitments, with appropriate earmarking or segregation of assets to cover such obligation. With respect to investments in commodities, the 1940 Act presently permits the Fund to invest in commodities in accordance with investment policies contained in its prospectus and SAI. Any such investment shall also comply with the Commodity Exchange Act and the rules and regulations thereunder. The 1940 Act does not directly restrict an investment company’s ability to invest in real estate, but does require that every investment company have the fundamental investment policy governing such investments. The Fund will not purchase or sell real estate, except that the Fund may invest in companies that deal in real estate (including REITs) or in instruments that are backed or secured by real estate.

EXCHANGE LISTING AND TRADING

A discussion of exchange listing and trading matters associated with an investment in the Fund is contained in the Prospectus under “PURCHASE AND SALE INFORMATION” and “ADDITIONAL PURCHASE AND SALE INFORMATION.” The discussion below supplements, and should be read in conjunction with, such sections of the Prospectus.

The Shares of the Fund are approved for listing and trading on the Exchange, subject to notice of issuance. The Shares trade on the Exchange at prices that may differ to some degree from their net asset value. There can be no assurance that the requirements of the Exchange necessary to maintain the listing of Shares of the Fund will continue to be met.

The Exchange may, but is not required to, remove the Shares of the Fund from listing if: (1) following the initial twelve-month period beginning upon the commencement of trading of the Fund, there are fewer than 50 beneficial holders of the Shares for 30 or more consecutive trading days; (2) the value of its underlying Index or portfolio of securities on which the Fund is based is no longer calculated or available; (3) the “indicative optimized portfolio value” (“IOPV”) of the Fund is no longer calculated or available; or (4) such other event shall occur or condition exists that, in the opinion of the Exchange, makes further dealings on the Exchange inadvisable. In addition, the Exchange will remove the Shares from listing and trading upon termination of the Trust or the Fund.

The Trust reserves the right to adjust the Share price of the Fund in the future to maintain convenient trading ranges for investors. Any adjustments would be accomplished through stock splits or reverse stock splits, which would have no effect on the net assets of the Fund.

As in the case of other publicly traded securities, brokers’ commissions on transactions will be based on negotiated commission rates at customary levels.

The base and trading currencies of the Fund is the U.S. dollar. The base currency is the currency in which the Fund’s net asset value per Share is calculated and the trading currency is the currency in which Shares of the Fund are listed and traded on the Exchange.
