INVESTMENT SECURITIES AND RISKS

The following descriptions of investment securities, risks and limitations supplement those set forth in the fund’s prospectus and may be changed without shareholder approval, unless otherwise noted. The fund will invest in securities or engage in techniques that are intended to help achieve its investment objective.

Borrowing may subject the fund to interest costs, which may exceed the interest received on the securities purchased with the borrowed funds. The fund normally may borrow at times to meet redemption requests rather than sell portfolio securities to raise the necessary cash. The fund may borrow money from banks and make other investments or engage in other transactions permissible under the Investment Company Act of 1940, as amended (the 1940 Act), which may be considered a borrowing (such as mortgage dollar rolls and reverse repurchase agreements).

The fund may establish lines-of-credit (lines) with certain banks by which it may borrow funds for temporary or emergency purposes. A borrowing is presumed to be for temporary or emergency purposes if it is (a) not in excess of 5% of a fund’s total assets; (b) repaid by a fund within 60 days; and (c) not extended or renewed. The fund intends to use the lines to meet large or unexpected redemptions that would otherwise force the fund to liquidate securities under circumstances that are unfavorable to the fund’s remaining shareholders. The fund will pay a fee to the bank for using its lines.

Borrowing can also involve leveraging when securities are purchased with the borrowed money. Leveraging creates interest expenses that can exceed the income from the assets purchased with the borrowed money. In addition, leveraging may magnify changes in the net asset value of the fund’s shares and in its portfolio yield. The fund will earmark or segregate assets to cover such borrowings in accordance with positions of the Securities and Exchange Commission (“SEC”). If assets used to secure a borrowing decrease in value, a fund may be required to pledge additional collateral to avoid liquidation of those assets.

Concentration means that substantial amounts of assets are invested in a particular industry or group of industries. The fund has a policy to concentrate its investments in securities of real estate companies and other companies related to the real estate industry.

Based on the characteristics of mortgage-backed securities (“MBS”), the fund has identified MBS issued by private lenders and not guaranteed by U.S. government agencies or instrumentalities as a separate industry for purposes of the fund’s concentration policy.

For purposes of the fund’s concentration policy, the fund will determine the industry classification of asset-backed securities based upon the investment adviser’s evaluation of the risks associated with an investment in the underlying assets. For example, asset-backed securities whose underlying assets share similar economic characteristics because, for example, they are funded (or supported) primarily from a single or similar source or revenue stream will be classified in the same industry sector. In contrast, asset-backed securities whose underlying assets represent a diverse mix of industries, business sectors and/or revenue streams will be classified into distinct industries based on their underlying credit and liquidity structures. With the exception of the real estate industry, the fund will limit its investments in each identified industry to less than 25% of its total assets.

Debt Securities are obligations issued by domestic and foreign entities, including governments and corporations, in order to raise money. They are basically “IOUs,” but are commonly referred to as bonds or money market securities. These securities normally require the issuer to pay a fixed, variable or floating rate of interest on the amount of money borrowed (the “principal”) until it is paid back upon maturity.

Debt securities experience price changes when interest rates change. For example, when interest rates fall, the prices of debt securities generally rise. Also, issuers tend to pre-pay their outstanding debts and issue new ones paying lower interest rates. This is especially true for bonds with sinking fund provisions, which commit the issuer to set aside a certain amount of money to cover timely repayment of principal and typically allow the issuer to annually repurchase certain of its outstanding bonds from the open market or at a pre-set call price.

Conversely, in a rising interest rate environment, prepayment on outstanding debt securities generally will not occur. This is known as extension risk and may cause the value of debt securities to depreciate as a result of the higher market interest rates. Typically, longer-maturity securities react to interest rate changes more severely than shorter-term securities (all things being equal), but generally offer greater rates of interest.

When short- and long-term interest rates are low, a change in the Federal Reserve’s monetary policy or improving economic conditions may lead to an increase in interest rates, which could significantly impact the value of debt securities in which the fund invests. Some debt securities are more sensitive to interest rate changes than others and may experience an immediate and considerable reduction in value if interest rates rise. Longer duration securities tend to be more volatile than shorter duration securities. As the values of debt securities in the fund’s portfolio adjust to a rise in interest rates, the fund’s share price may fall. In the event that the fund holds a large portion of its portfolio in longer duration securities when interest rates increase, the share price of the fund may fall significantly.

Debt securities also are subject to the risk that the issuers will not make timely interest and/or principal payments or fail to make them at all. This is called credit risk. Corporate debt securities (bonds) tend to have higher credit risk generally than U.S. government debt securities. Debt securities also may be subject to price volatility due to market perception of future interest rates, the creditworthiness of the issuer and general market liquidity (market risk). Investment-grade debt securities are considered medium- and/or

3

Table of Contents

high-quality securities, although some still possess varying degrees of speculative characteristics and risks. Debt securities rated below investment-grade are riskier, but may offer higher yields. These securities are sometimes referred to as high yield securities or “junk bonds.”

Corporate bonds are debt securities issued by corporations. Although a higher return is expected from corporate bonds, these securities, while subject to the same general risks as U.S. government securities, are subject to greater credit risk than U.S. government securities. Their prices may be affected by the perceived credit quality of their issuer.

Certain debt securities have provisions that allow the issuer to redeem or “call” a bond before its maturity at a price below or above its current market value. Issuers are most likely to call these securities during periods of falling interest rates. When this happens, the fund may have to replace these securities with lower yielding securities, which could result in a lower return.

See Appendix A for a full description of the various ratings assigned to debt securities by various nationally recognized statistical rating organizations (“NRSROs”).

High Yield Securities , also called lower quality bonds (“junk bonds”), are frequently issued by companies without long track records of sales and earnings, or by those of questionable credit strength, and are more speculative and volatile (though typically higher yielding) than investment grade bonds. Adverse economic developments could disrupt the market for high yield securities, and severely affect the ability of issuers, especially highly-leveraged issuers, to service their debt obligations or to repay their obligations upon maturity.

Also, the secondary market for high yield securities at times may not be as liquid as the secondary market for higher-quality debt securities. As a result, the investment adviser could find it difficult to sell these securities or experience difficulty in valuing certain high yield securities at certain times. Prices realized upon the sale of such lower rated securities, under these circumstances, may be less than the prices at which the fund purchased them.

Thus, high yield securities are more likely to react to developments affecting interest rates and market and credit risk than are more highly rated securities, which primarily react to movements in the general level of interest rates. When economic conditions appear to be deteriorating, medium- to lower-quality debt securities may decline in value more than higher-quality debt securities due to heightened concern over credit quality, regardless of prevailing interest rates. Prices for high yield securities also could be affected by legislative and regulatory developments. These laws could adversely affect the fund’s net asset value and investment practices, the secondary market value for high yield securities, the financial condition of issuers of these securities and the value of outstanding high yield securities.

Inflation-Protected Securities are fixed income securities whose value is periodically adjusted according to the rate of inflation. Two structures are common. The U.S. Treasury and some other issuers utilize a structure that accrues inflation into the principal value of the bond. Other issuers pay out the Consumer Price Index (“CPI”) accruals as part of a semiannual coupon.

Inflation protected securities issued by the U.S. Treasury have maturities of approximately five, ten or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis equal to a fixed percentage of the inflation adjusted principal amount.

Table of Contents

If the periodic adjustment rate measuring inflation falls, the principal value of inflation protected bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed by the U.S. Treasury in the case of U.S. Treasury inflation protected bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed and will fluctuate. The fund may also invest in other inflation related bonds which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond to be repaid at maturity may be less than the original principal amount and, therefore, is subject to credit risk.

The value of inflation protected bonds is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if the rate of inflation rises at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation protected bonds. In contrast, if nominal interest rates increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation protected bonds.

While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

The periodic adjustment of U.S. inflation-protected bonds is tied to the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers (“CPI-U”), published monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation protected bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index calculated by that government. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States.

Any increase in principal for an inflation protected security resulting from inflation adjustments is considered by the U.S. Internal Revenue Service (“IRS”) to be taxable income in the year it occurs. The fund’s distributions to shareholders include interest income and the income attributable to principal adjustments, both of which will be taxable to shareholders. The tax treatment of the income attributable to principal adjustments may result in the situation where the fund needs to make its required annual distributions to shareholders in amounts that exceed the cash received. As a result, the fund may need to liquidate certain investments when it is not advantageous to do so. Also, if the principal value of an inflation protected security is adjusted downward due to deflation, amounts previously distributed in the taxable year may be characterized in some circumstances as a return of capital.

International Bonds are certain obligations or securities of foreign issuers, including Eurodollar Bonds, which are U.S. dollar-denominated bonds issued by foreign issuers payable in Eurodollars (U.S. dollars held in banks located outside the United States, primarily Europe), Yankee Bonds, which are U.S. dollar-denominated bonds issued in the U.S. by foreign banks and corporations, and EuroBonds, which are bonds denominated in U.S. dollars and usually issued by large underwriting groups composed of banks and issuing houses from many countries. Investments in securities issued by foreign issuers, including American Depositary Receipts (“ADRs”) and securities purchased on foreign securities exchanges, may subject the fund to additional investment risks, such as adverse political and economic developments, possible seizure, nationalization or expropriation of foreign investments, less stringent disclosure requirements, non-U.S. withholding taxes and the adoption of other foreign governmental restrictions.

Additional risks include less publicly available information, the risk that companies may not be subject to the accounting, auditing and financial reporting standards and requirements of U.S. companies, the risk that foreign securities markets may have less volume and therefore may be less liquid and their prices more volatile than U.S. securities, and the risk that custodian and transaction costs may be higher. Foreign issuers of securities or obligations are often subject to accounting requirements and engage in business practices different from those respecting domestic issuers of similar securities or obligations. Foreign branches of U.S. banks and foreign banks may be subject to less stringent reserve requirements than those applicable to domestic branches of U.S. banks.

Loan Interests, and other direct debt instruments or interests therein, may be acquired by the fund. A loan interest is typically originated, negotiated, and structured by a U.S. or foreign commercial bank, insurance company, finance company, or other financial institution (“Agent”) for a lending syndicate of financial institutions. The Agent typically administers and enforces the loan on behalf of the other lenders in the syndicate. In addition, an institution typically but not always the Agent (“Collateral Bank”), holds collateral (if any) on behalf of the lenders. When a Collateral Bank holds collateral, such collateral typically consists of one or more of the following asset types: inventory, accounts receivable, property, plant and equipment, intangibles, common stock of subsidiaries or other investments. These loan interests may take the form of participation interests in, assignments of or novations of a loan during its second distribution, or direct interests during a primary distribution. Such loan interests may be acquired from U.S. or foreign banks, insurance companies, finance companies, or other financial institutions that have made loans or are members of a lending syndicate or from other holders of loan interests. The fund may also acquire loan interests under which the fund derives its rights directly from the borrower. Such loan interests are separately enforceable by the fund against the borrower and all payments of interest and principal are typically made directly to the fund from the borrower. In the event that the fund and other lenders become entitled to take possession of shared collateral, it is anticipated that such collateral would be held in the custody of the Collateral Bank for their mutual benefit. The fund may not act as an Agent, a Collateral Bank, a guarantor or sole negotiator or structurer with respect to a loan. The investment adviser will analyze and evaluate the financial condition of the borrower in connection with the acquisition of any loan interest. Credit ratings are typically assigned to loan interests in the same manner as with other fixed income debt securities, and the investment adviser analyzes and evaluates these ratings, if any, in deciding whether to purchase a loan interest. The investment adviser also analyzes and evaluates the financial condition of the Agent and, in the case of loan interests in which the fund does not have privity with the borrower, those institutions from or through whom the fund derives its rights in a loan (“Intermediate Participants”).

In a typical loan, the Agent administers the terms of the loan agreement. In such cases, the Agent is normally responsible for the collection of principal and interest payments from the borrower and the apportionment of these payments to the credit of all the institutions that are parties to the loan agreement. The fund will generally rely upon the Agent or Intermediate Participant to receive and forward to the fund its portion of the principal and interest payments on the loan. Furthermore, unless under the terms of a participation agreement the fund has direct recourse against the borrower, the fund will rely on the Agent and the other members of the lending syndicate to use appropriate credit remedies against the borrower. The Agent is typically responsible for monitoring compliance with covenants contained in the loan agreement based upon reports prepared by the borrower. The seller of the loan interest usually does, but is often not obligated to, notify holders of loan interests of any failures of compliance. The Agent may monitor the value of the collateral and, if the value of the collateral declines, may accelerate the loan, may give the borrower an opportunity to provide additional collateral or may seek other protection for the benefit of the participants in the loan. The Agent is compensated by the borrower for providing these services under a loan agreement, and such compensation may include special fees paid upon structuring and funding the loan and other fees paid on a continuing basis. With respect to loan interests for which the Agent does not perform such administrative and enforcement functions, the fund will perform such tasks on its own behalf, although a Collateral Bank will typically hold any collateral on behalf of the fund and the other holders pursuant to the applicable loan agreement.

A financial institution’s appointment as Agent may usually be terminated in the event that it fails to observe the requisite standard of care or becomes insolvent, enters Federal Deposit Insurance Corporation (“FDIC”) receivership, or, if not FDIC insured, enters into bankruptcy proceedings. A successor agent generally would be appointed to replace the terminated Agent, and assets held by the Agent under the loan agreement should remain available to holders of loan interests. However, if assets held by the Agent for the benefit of the fund were determined to be subject to the claims of the Agent’s general creditors, the fund might incur certain costs and delays in realizing payment on a loan interest, or suffer a loss of principal and/or interest. In situations involving Intermediate Participants, similar risks may arise.

Purchasers of loan interests depend primarily upon the creditworthiness of the borrower for payment of principal and interest. If the fund does not receive a scheduled interest or principal payment on such indebtedness, the fund’s share price and yield could be adversely affected. Loans that are fully secured offer the fund more protections than an unsecured loan in the event of non-payment of scheduled interest or principal. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the borrower’s obligation, or that the collateral can be liquidated. Indebtedness of borrowers whose creditworthiness is poor involves substantially greater risks, and may be highly speculative. Borrowers that are in bankruptcy or restructuring may never pay off their indebtedness, or may pay only a small fraction of the amount owed. Direct indebtedness of developing countries also will involve a risk that the governmental entities responsible for the repayment of the debt may be unable, or unwilling, to pay interest and repay principal when due.

The loan interests market is in a developing phase with increased participation among several investor types. The dealer community has become increasingly involved in this secondary market. If, however, a particular loan interest is deemed to be illiquid, it would be valued using procedures adopted by the Board of Trustees. In such a situation, there is no guarantee that the fund will be able to sell such loan interests, which could lead to a decline in the value of the loan interests and the value of the fund’s shares.

Loan Participations. The fund may purchase participations in commercial loans. Such indebtedness may be secured or unsecured. Loan participations typically represent direct participation in a loan to a corporate borrower, and generally are offered by banks or other financial institutions or lending syndicates. The fund may participate in such syndications, or can buy part of a loan, becoming a part lender. When purchasing loan participations, the fund assumes the credit risk associated with the corporate borrower and may assume the credit risk associated with an interposed bank or other financial intermediary. The participation interests in which the fund intends to invest may not be rated by any nationally recognized rating service.

A loan is often administered by an agent bank acting as agent for all holders. The agent bank administers the terms of the loan, as specified in the loan agreement. In addition, the agent bank is normally responsible for the collection of principal and interest payments from the corporate borrower and the apportionment of these payments to the credit of all institutions which are parties to the loan agreement. Unless, under the terms of the loan or other indebtedness, the fund has direct recourse against the corporate borrower, the fund may have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies against a corporate borrower.

A financial institution’s employment as agent bank might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent bank would generally be appointed to replace the terminated agent bank, and assets held by the agent bank under the loan agreement should remain available to holders of such indebtedness. However, if assets held by the agent bank for the benefit

of the fund were determined to be subject to the claims of the agent bank’s general creditors, the fund might incur certain costs and delays in realizing payment on a loan or loan participation and could suffer a loss of principal and/or interest. In situations involving other interposed financial institutions (e.g., an insurance company or governmental agency) similar risks may arise.

Purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the corporate borrower for payment of principal and interest. If the fund does not receive scheduled interest or principal payments on such indebtedness, the fund’s share price and yield could be adversely affected. Loans that are fully secured offer the fund more protection than an unsecured loan in the event of non-payment of scheduled interest or principal. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower’s obligation, or that the collateral can be liquidated.

The fund may invest in loan participations with credit quality comparable to that of issuers of its securities investments. Indebtedness of companies whose creditworthiness is poor involves substantially greater risks, and may be highly speculative. Some companies may never pay off their indebtedness, or may pay only a small fraction of the amount owed. Consequently, when investing in indebtedness of companies with poor credit, the fund bears a substantial risk of losing the entire amount invested.

The fund limits the amount of its total assets that it will invest in any one issuer or in issuers within the same industry. For purposes of these limits, the fund generally will treat the corporate borrower as the “issuer” of indebtedness held by the fund. In the case of loan participations where a bank or other lending institution serves as a financial intermediary between the fund and the corporate borrower, if the participation does not shift to the fund the direct debtor-creditor relationship with the corporate borrower, SEC interpretations require the fund to treat both the lending bank or other lending institution and the corporate borrower as “issuers” for the purposes of determining whether the fund has invested more than 5% of its assets in a single issuer. Treating a financial intermediary as an issuer of indebtedness may restrict the fund’s ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

Loans and other types of direct indebtedness may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what the investment adviser believes to be a fair price. In addition, valuation of illiquid indebtedness involves a greater degree of judgment in determining the fund’s net asset value than if that value were based on available market quotations, and could result in significant variations in the fund’s daily share price. At the same time, some loan interests are traded among certain financial institutions and accordingly may be deemed liquid. As the market for different types of indebtedness develops, the liquidity of these instruments is expected to improve. In addition, the fund currently intends to treat indebtedness for which there is no readily available market as illiquid for purposes of the fund’s limitation on illiquid investments. Investments in loan participations are considered to be debt obligations for purposes of the fund’s investment restriction relating to the lending of funds or assets by the fund.

Investments in loans through a direct assignment of the financial institution’s interests with respect to the loan may involve additional risks to the fund. For example, if a loan is foreclosed, the fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that under emerging legal theories of lender liability, the fund could be held liable as co-lender. It is unclear whether loans and other forms of direct indebtedness offer securities law protections against fraud and misrepresentation. In the absence of definitive regulatory guidance, the fund relies on the investment adviser’s research in an attempt to avoid situations where fraud or misrepresentation could adversely affect the fund.

Maturity of Investments will generally be determined using a portfolio security’s final maturity date (date on which the final principal payment of a bond is scheduled to be paid); however, for securitized products, such as MBS and certain other asset-backed securities, maturity will be determined on an average life basis (weighted average time to receipt of all principal payments) by the investment adviser. Because pre-payment rates of individual mortgage pools vary widely, the average life of a particular pool cannot be predicted precisely. For securities with embedded demand features, such as puts or calls, either the demand date or the final maturity date will be used depending on interest rates, yields and other market conditions. The average portfolio maturity of the fund is dollar-weighted based upon the market value of the fund’s securities at the time of the calculation.

Stripped Securities are securities whose income and principal components are detached and sold separately. While risks associated with stripped securities are similar to other fixed income securities, stripped securities are typically subject to greater changes in value. U.S. Treasury securities that have been stripped by the Federal Reserve Bank are obligations of the U.S. Treasury. Privately stripped government securities are created when a dealer deposits a U.S. Treasury security or other U.S. government security with a custodian for safekeeping; the custodian issues separate receipts for the coupon payments and the principal payment, which the dealer then sells. There are two types of stripped securities: coupon strips, which refer to the zero coupon bonds that are backed by the coupon payments; and principal strips, which are backed by the final repayments of principal. Unlike coupon strips, principal strips do not accrue a coupon payment. They are sold at a discounted price and accrete up to par. An investor in a principal strip would only need to pay capital gains tax on the principal strip.

The funds may invest in U.S. Treasury bonds that have been stripped of their unmatured interest coupons, the coupons themselves, and receipts or certificates representing interests in such stripped debt obligations and coupons. Interest on zero coupon bonds is accrued and paid at maturity rather than during the term of the security. Such obligations have greater price volatility than coupon obligations and other normal interest-paying securities, and the value of zero coupon securities reacts more quickly to changes in interest rates than do coupon bonds. Because dividend income is accrued throughout the term of the zero coupon obligation, but it is not actually received until maturity, a fund may have to sell other securities to pay accrued dividends prior to the maturity of the zero coupon obligation.

Unlike regular U.S. Treasury bonds which pay semi-annual interest, U.S. Treasury zero coupon bonds do not generate semi-annual coupon payments. Instead, zero coupon bonds are purchased at a substantial discount from the maturity of such securities. The discount reflects the current value of the deferred interest and is amortized as interest income over the life of the securities; it is taxable even though there is no cash return until maturity.

Zero coupon U.S. Treasury issues originally were created by government bond dealers who bought U.S. Treasury bonds and issued receipts representing an ownership interest in the interest coupons or the principal portion of the bonds. Subsequently, the U.S. Treasury began directly issuing zero coupon bonds with the introduction of the Separate Trading of Registered Interest and Principal of Securities (“STRIPS”) program. Under the STRIPS program, the principal and interest components are separately issued by the U.S. Treasury at the request of depository financial institutions, which then trade the component parts separately.

While zero coupon bonds eliminate the reinvestment risk of regular coupon issues, i.e., the risk of subsequently investing the periodic interest payments at a lower rate than that of the security currently held, zero coupon bonds fluctuate much more sharply than regular coupon-bearing bonds. Thus, when interest rates rise, the value of zero coupon bonds will decrease to a greater extent than will the value of regular bonds having the same interest rate.

Variable- and Floating-Rate Debt Securities pay an interest rate, which is adjusted either periodically or at specific intervals or which floats continuously according to a formula or benchmark. Although these structures generally are intended to minimize the fluctuations in value that occur when interest rates rise and fall, some structures may be linked to a benchmark in such a way as to cause greater volatility to the security’s value.

Some variable-rate securities may be combined with a put or demand feature (variable-rate demand securities) that entitles the holder to the right to demand repayment in full or to resell at a specific price and/or time. While the demand feature is intended to reduce credit risks, it is not always unconditional, and may be subject to termination if the issuer’s credit rating falls below investment grade or if the issuer fails to make payments on other debt. While most variable-rate demand securities allow a fund to exercise its demand rights at any time, some such securities may only allow a fund to exercise its demand rights at certain times, which reduces the liquidity usually associated with this type of security. A fund could suffer losses in the event that the demand feature provider, usually a bank, fails to meet its obligation to pay the demand.

Synthetic variable or floating rate securities include tender option bond receipts. Tender option bond receipts are derived from fixed-rate municipal bonds that are placed in a trust that also contains a liquidity facility. The trust issues two classes of receipts, one of which is a synthetic variable-rate demand obligation and one of which is an inverse-rate long-term obligation; each obligation represents a proportionate interest in the underlying bonds. The remarketing agent for the trust sets a floating or variable rate on typically a weekly basis. The synthetic variable-rate demand obligations, or floater receipts, grant the investors (floater holders) the right to require the liquidity provider to purchase the receipts at par, on a periodic (e.g., daily, weekly or monthly) basis. The trust receives the interest income paid by the issuer of the underlying bonds and, after paying fees to the trustee, remarketing agent and liquidity provider, the remaining income is paid to the floater holders based on the prevailing market rate set by the remarketing agent and the remaining (or inverse) amount is paid to the long-term investor. The trust is collapsed prior to the maturity of the bonds and the receipts holders may participate in any gain realized from the sale of the bonds at that time. In the event of certain defaults or a significant downgrading in the credit rating assigned to the issuer of the bond, the liquidity facility provider may not be obligated to accept tendered floater receipts. In this event, the underlying bonds in the trust are priced for sale in the market and the proceeds are used to repay the floater and inverse receipt holders. If the receipts holders cannot be repaid in full from the sale of the underlying bonds then the bonds will be distributed to the receipts holders on a pro-rata basis, in which case the holders would anticipate a loss. Tender option bonds may be considered derivatives and are subject to the risk thereof.

The funds may invest in tender option bonds the interest on which will, in the opinion of bond counsel or counsel for the issuer of interests therein, be exempt from regular federal income tax. Tender option bond trust receipts generally are structured as private placements and, accordingly, may be deemed to be restricted securities for purposes of a fund’s investment limitations.

Depositary Receipts, including ADRs as well as other “hybrid” forms of ADRs, including European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs), are certificates evidencing ownership of shares of a foreign issuer. Depositary receipts may be sponsored or unsponsored. These certificates are issued by depository banks and generally trade on an established market in the United States or elsewhere. The underlying shares are held in trust by a custodian bank or similar financial institution in the issuer’s home country. The depository bank may not have physical custody of the underlying securities at all times and may charge fees for various services, including forwarding

10

Table of Contents

dividends and interest and corporate actions. ADRs are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. However, ADRs continue to be subject to many of the risks associated with investing directly in foreign securities.

Investments in the securities of foreign issuers may subject the fund to investment risks that differ in some respects from those related to investments in securities of U.S. issuers. Such risks include future adverse political and economic developments, possible imposition of withholding taxes on income, possible seizure, nationalization or expropriation of foreign deposits, possible establishment of exchange controls or taxation at the source or greater fluctuation in value due to changes in exchange rates. Foreign issuers of securities often engage in business practices different from those of domestic issuers of similar securities, and there may be less information publicly available about foreign issuers. In addition, foreign issuers are, generally speaking, subject to less government supervision and regulation and different accounting treatment than are those in the United States.

Although the two types of depositary receipt facilities (unsponsored or sponsored) are similar, there are differences regarding a holder’s rights and obligations and the practices of market participants. A depository may establish an unsponsored facility without participation by (or acquiescence of) the underlying issuer; typically, however, the depository requests a letter of non-objection from the underlying issuer prior to establishing the facility. Holders of unsponsored depositary receipts generally bear all the costs of the facility. The depository usually charges fees upon the deposit and withdrawal of the underlying securities, the conversion of dividends into U.S. dollars or other currency, the disposition of non-cash distributions, and the performance of other services. The depository of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the underlying issuer or to pass through voting rights to depositary receipt holders with respect to the underlying securities.

Sponsored depositary receipt facilities are created in generally the same manner as unsponsored facilities, except that sponsored depositary receipts are established jointly by a depository and the underlying issuer through a deposit agreement. The deposit agreement sets out the rights and responsibilities of the underlying issuer, the depository, and the depositary receipt holders. With sponsored facilities, the underlying issuer typically bears some of the costs of the depositary receipts (such as dividend payment fees of the depository), although most sponsored depositary receipts holders may bear costs such as deposit and withdrawal fees. Depositories of most sponsored depositary receipts agree to distribute notices of shareholder meetings, voting instructions, and other shareholder communications and information to the depositary receipt holders at the underlying issuer’s request.

Derivative Instruments are commonly defined to include securities or contracts whose values depend on (or “derive” from) the value of one or more other assets such as securities, currencies, or commodities. These “other assets” are commonly referred to as “underlying assets.”

A derivative instrument generally consists of, is based upon, or exhibits characteristics similar to options or forward contracts. Options and forward contracts are considered to be the basic “building blocks” of derivatives. For example, forward-based derivatives include forward contracts, as well as exchange-traded futures. Option-based derivatives include privately negotiated, over-the-counter (OTC) options (including caps, floors, collars, and options on forward and swap contracts) and exchange-traded options on futures. Diverse types of derivatives may be created by combining options or forward contracts in different ways, and applying these structures to a wide range of underlying assets. Risk management strategies include investment techniques designed to facilitate the sale of portfolio securities, manage the average duration of the portfolio or create or alter exposure to certain asset classes, such as equity, other debt or foreign securities.

In addition to the derivative instruments and strategies described in this SAI, the investment adviser expects to discover additional derivative instruments and other investment, hedging or risk management techniques. The investment adviser may utilize these new derivative instruments and techniques to the extent that they are consistent with the fund’s investment objective and permitted by the fund’s investment limitations, operating policies, and applicable regulatory authorities.

Credit Default Swaps may be entered into for investment purposes. As the seller in a credit default swap contract, the fund would be required to pay the par (or other agreed-upon) value of a referenced debt obligation to the counterparty in the event of a default by a third party, such as a U.S. or foreign corporate issuer, on the debt obligation. In return, the fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the fund would keep the stream of payments and would have no payment obligations. As the seller, the fund would be subject to investment exposure on the notional amount of the swap.

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

Credit and Liquidity Supports or Enhancements may be employed by issuers or the fund to reduce the credit risk of their securities. Credit supports include letters of credit, insurance, total return and credit swap agreements and guarantees provided by foreign and domestic financial institutions. Liquidity supports include puts, demand features, and lines of credit. Most of these arrangements move the credit risk of an investment from the issuer of the security to the support provider. The investment adviser may rely on its evaluation of the credit and liquidity support provider in determining whether to purchase or hold a security enhanced by such a support. Changes in the credit quality of a support provider could cause losses to the fund.

Forward Contracts are sales contracts between a buyer (holding the “long” position) and the seller (holding the “short” position) for an asset with delivery deferred to a future date. The buyer agrees to pay a fixed price at the agreed future date and the seller agrees to deliver the asset. The seller hopes that the market price on the delivery date is less than the agreed upon price, while the buyer hopes for the contrary. The change in value of a forward-based derivative generally is roughly proportional to the change in value of the underlying asset.

Futures Contracts are instruments that represent an agreement between two parties that obligates one party to buy, and the other party to sell, specific instruments at an agreed-upon price on a stipulated future date. In the case of futures contracts relating to an index or otherwise not calling for physical delivery at the close of the transaction, the parties usually agree to deliver the final cash settlement price of the contract. The fund may purchase and sell futures contracts based on securities, securities indices and foreign currencies, interest rates, or any other futures contracts traded on U.S. exchanges or boards of trade that the Commodities Future Trading Commission (“CFTC”) licenses and regulates on foreign exchanges. Consistent with CFTC regulations, the fund has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act and, therefore, is not subject to registration or regulation as a pool operator. However, investors should note that the CFTC has adopted certain rules that significantly affect the exclusion available to the fund. CFTC rules require that the fund claiming an exclusion from commodity pool operator registration limit its trades in futures contracts with certain limited exceptions. If the fund is unable to claim an exclusion from registration, the fund’s adviser may be required to register as a commodity pool operator and comply with certain CFTC rules.

Additional CFTC regulation may cause the fund to change its investment strategies or to incur additional expenses.

The fund must maintain a small portion of its assets in cash to process shareholder transactions and to pay its expenses. In order to reduce the effect this otherwise uninvested cash would have on its performance the fund may purchase futures contracts. Such transactions allow the fund’s cash balance to produce a return similar to that of the underlying security or index on which the futures contract is based. Also, the fund may purchase or sell futures contracts on a specified foreign currency to “fix” the price in U.S. dollars of the foreign security it has acquired or sold or expects to acquire or sell. The fund may enter into futures contracts for other reasons as well.

When buying or selling futures contracts, the fund must place a deposit with its broker equal to a fraction of the contract amount. This amount is known as “initial margin” and must be in the form of liquid debt instruments, including cash, cash-equivalents and U.S. government securities. Subsequent payments to and from the broker, known as “variation margin,” may be made daily, if necessary, as the value of the futures contracts fluctuate. This process is known as “marking-to-market.” The margin amount will be returned to the fund upon termination of the futures contracts assuming all contractual obligations are satisfied. Because margin requirements are normally only a fraction of the amount of the futures contracts in a given transaction, futures trading can involve a great deal of leverage. In order to avoid this, the fund will earmark or segregate assets for any outstanding futures contracts as may be required by the federal securities laws.

While the fund may purchase and sell futures contracts in order to simulate full investment, there are risks associated with these transactions. Adverse market movements could cause the fund to experience substantial losses when buying and selling futures contracts. Of course, barring significant market distortions, similar results would have been expected if the fund had instead transacted in the underlying securities directly. There also is the risk of losing any margin payments held by a broker in the event of its bankruptcy. Additionally, the fund incurs transaction costs (i.e. brokerage fees) when engaging in futures trading. To the same extent the fund invests in futures in order to simulate full investment, these same risks apply.

When interest rates are rising or securities prices are falling, the fund may seek, through the sale of futures contracts, to offset a decline in the value of its current portfolio securities. When interest rates are falling or prices are rising, the fund, through the purchase of futures contracts, may attempt to secure better rates or prices than might later be available in the market when they effect anticipated purchases. Similarly, the fund may sell futures contracts on a specified currency to protect against a decline in the value of that currency and its portfolio securities that are denominated in that currency. The fund may purchase futures contracts on a foreign currency to fix the price in U.S. dollars of a security denominated in that currency that the fund has acquired or expects to acquire.

Futures contracts normally require actual delivery or acquisition of an underlying security or cash value of an index on the expiration date of the contract. In most cases, however, the contractual obligation is fulfilled before the date of the contract by buying or selling, as the case may be, identical futures contracts. Such offsetting transactions terminate the original contracts and cancel the obligation to take or make delivery of the underlying securities or cash. There may not always be a liquid secondary market at the time the fund seeks to close out a futures position. If the fund is unable to close out its position and prices move adversely, the fund would have to continue to make daily cash payments to maintain its margin requirements. If the fund had insufficient cash to meet these requirements it may have to sell portfolio securities at a disadvantageous time or incur extra costs by borrowing the cash. Also, the fund may be required to make or take delivery and incur extra transaction costs buying or selling the underlying securities. The fund would seek to reduce the risks associated with futures transactions by buying and selling futures contracts that are traded on national exchanges or for which there appears to be a liquid secondary market.

With respect to futures contracts that are not legally required to “cash settle,” the fund may cover the open position by setting aside or earmarking liquid assets in an amount equal to the market value of the futures contracts. With respect to futures contracts that are required to “cash settle,” however, the fund is permitted to set aside or earmark liquid assets in an amount equal to the fund’s daily marked to market (net) obligation, if any, (in other words, the fund’s daily net liability, if any) rather than the market value of the futures contracts. By setting aside assets or earmarking equal to only its net obligation under cash-settled futures, the fund will have the ability to employ leverage to a greater extent than if the fund were required to set aside or earmark assets equal to the full market value of the futures contract.

Hybrid Instruments are a type of potentially high-risk derivative that combines a traditional stock, bond, or commodity with an option or forward contract. Generally, the principal amount, amount payable upon maturity or redemption, or interest rate of a hybrid is tied (positively or negatively) to the price of some commodity, currency or securities index or another interest rate or some other economic factor (each a “benchmark”). The interest rate or (unlike most fixed income securities) the principal amount payable at maturity of a hybrid security may be increased or decreased, depending on changes in the value of the benchmark. An example of a hybrid could be a bond issued by an oil company that pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid instrument would be a combination of a bond and a call option on oil.

Hybrids can be used as an efficient means of pursuing a variety of investment goals, including currency hedging, duration management, and increased total return. Hybrids may not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond that has a fixed principal amount and pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes the fund to the credit risk of the issuer of the hybrids. These risks may cause significant fluctuations in the net asset value of the fund. The fund will not invest more than 5% of its total assets in hybrid instruments.

Certain hybrid instruments may provide exposure to the commodities markets. These are derivative securities with one or more commodity-linked components that have payment features similar to commodity futures contracts, commodity options, or similar instruments. Commodity-linked hybrid instruments may be either equity or debt securities, and are considered hybrid instruments because they have both security and commodity-like characteristics. A portion of the value of these instruments may be derived from the value of a commodity, futures contract, index or other economic variable. The fund will only invest in commodity-linked hybrid instruments that qualify under applicable rules of the CFTC for an exemption from the provisions of the CEA.

Certain issuers of structured products such as hybrid instruments may be deemed to be investment companies as defined in the 1940 Act. As a result, the fund’s investments in these products may be subject to limits applicable to investments in investment companies and may be subject to restrictions contained in the 1940 Act.

Index Participations and index participation contracts provide the equivalent of a position in the securities comprising an index, with each security’s representation equaling its index weighting. Moreover, their holders are entitled to payments equal to the dividends paid by the underlying index securities. Generally, the value of an index participation or index participation contract will rise and fall along with the value of the related index. The fund will invest in index participation contracts only if a liquid market for them appears to exist.

Reverse Repurchase Agreements, Mortgage Dollar Rolls and Sale-Buybacks may be used by the fund. The fund may engage in reverse repurchase agreements to facilitate portfolio liquidity, a practice common in the mutual fund industry, or for arbitrage transactions as discussed below. In a reverse repurchase agreement, the fund would sell a security and enter into an agreement to repurchase the security at a specified future date and price. The fund generally retains the right to interest and principal payments on the security. Because the fund receives cash upon entering into a reverse repurchase agreement, it may be considered a borrowing. When required by guidelines of the SEC, the fund will set aside permissible liquid assets earmarked or in a segregated account to secure its obligations to repurchase the security.

The fund also may enter into mortgage dollar rolls, in which the fund would sell MBS for delivery in the current month and simultaneously contract to purchase substantially similar securities on a specified future date. While the fund would forego principal and interest paid on the MBS during the roll period, the fund would be compensated by the difference between the current sales price and the lower price for the future purchase as well as by any interest earned on the proceeds of the initial sale. The fund also could be compensated through the receipt of fee income equivalent to a lower forward price. At the time the fund would enter into a mortgage dollar roll, it would set aside permissible liquid assets earmarked or in a segregated account to secure its obligation for the forward commitment to buy MBS. This transaction allows the fund to have the same price and duration exposure in the mortgage security while having the cash for the bonds for the given time period. The net effect is that the fund is able to maintain mortgage exposure while having the cash available to facilitate redemptions. Mortgage dollar roll transactions may be considered a borrowing by the fund.

The mortgage dollar rolls and reverse repurchase agreements entered into by the fund may be used as arbitrage transactions in which the fund will maintain an offsetting position in short duration investment-grade debt obligations. Since the fund will receive interest on the securities or repurchase agreements in which it invests the transaction proceeds, such transactions may involve leverage. However, since such securities or repurchase agreements will be high quality and short duration, the investment adviser believes that such arbitrage transactions present lower risks to the fund than those associated with other types of leverage. There can be no assurance that the fund’s use of the cash it receives from a mortgage dollar roll will provide a positive return.

The fund also may effect simultaneous purchase and sale transactions that are known as “sale-buybacks.” A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty who purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the fund’s repurchase of the underlying security. The fund’s obligations under a sale-buyback typically would be offset by liquid assets equal in value to the amount of the fund’s forward commitment to repurchase the subject security.

Options Contracts generally provide the right to buy or sell a security, commodity, futures contract or foreign currency in exchange for an agreed upon price. If the right is not exercised after a specified period, the option expires and the option buyer forfeits the money paid to the option seller.

Table of Contents

A call option gives the buyer the right to buy a specified number of shares of a security at a fixed price on or before a specified date in the future. For this right, the call option buyer pays the call option seller, commonly called the call option writer, a fee called a premium. Call option buyers are usually anticipating that the price of the underlying security will rise above the price fixed with the call writer, thereby allowing them to profit. If the price of the underlying security does not rise, the call option buyer’s losses are limited to the premium paid to the call option writer. For call option writers, a rise in the price of the underlying security will be offset, in part, by the premium received from the call option buyer. If the call option writer does not own the underlying security, however, the losses that may ensue if the price rises could be potentially unlimited. If the call option writer owns the underlying security or commodity, this is called writing a covered call. All call options written by the fund will be covered, which means that the fund will own the securities subject to the option so long as the option is outstanding or the fund will earmark or segregate assets for any outstanding option contracts.

A put option is the opposite of a call option. It gives the buyer the right to sell a specified number of shares of a security at a fixed price on or before a specified date in the future. Put option buyers are usually anticipating a decline in the price of the underlying security, and wish to offset those losses when selling the security at a later date. All put options the fund writes will be covered, which means that the fund will earmark or segregate cash, U.S. government securities or other liquid securities with a value at least equal to the exercise price of the put option, or will otherwise “cover” its position as required by the 1940 Act (e.g., the fund will hold a put option on the same underlying security with the same or higher strike price). The purpose of writing such options is to generate additional income for the fund. However, in return for the option premium, the fund accepts the risk that it may be required to purchase the underlying securities at a price in excess of the securities’ market value at the time of purchase.

The fund may purchase and write put and call options on any securities in which it may invest or any securities index or basket of securities based on securities in which it may invest. In addition, the fund may purchase and sell foreign currency options and foreign currency futures contracts and related options. The fund may purchase and write such options on securities that are listed on domestic or foreign securities exchanges or traded in the over-the-counter market. Like futures contracts, option contracts are rarely exercised. Option buyers usually sell the option before it expires. Option writers may terminate their obligations under a written call or put option by purchasing an option identical to the one it has written. Such purchases are referred to as “closing purchase transactions.” The fund may enter into closing sale transactions in order to realize gains or minimize losses on options it has purchased or written.

An exchange-traded currency option position may be closed out only on an options exchange that provides a secondary market for an option of the same series. Although the fund generally will purchase or write only those options for which there appears to be an active secondary market, there is no assurance that a liquid secondary market will exist for any particular option or at any particular time. If the fund is unable to effect a closing purchase transaction with respect to options it has written, it will not be able to sell the underlying securities or dispose of assets earmarked or held in a segregated account until the options expire or are exercised. Similarly, if the fund is unable to effect a closing sale transaction with respect to options it has purchased, it would have to exercise the options in order to realize any profit and will incur transaction costs upon the purchase or sale of underlying securities.

Reasons for the absence of a liquid secondary market on an exchange include the following: (1) there may be insufficient trading interest in certain options; (2) an exchange may impose restrictions on opening transactions or closing transactions or both; (3) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (4) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (5) the facilities of an exchange or the Options Clearing Corporation (the “OCC”) may not at all times be adequate to handle current trading volume; or (6) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options), although outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

The ability to terminate over-the-counter options is more limited than with exchange-traded options and may involve the risk that broker-dealers participating in such transactions will not fulfill their obligations. Until such time as the staff of the SEC changes its position, the fund will treat purchased over-the-counter options and all assets used to cover written over-the-counter options as illiquid securities, except that with respect to options written with primary dealers in U.S. government securities pursuant to an agreement requiring a closing purchase transaction at a formula price, the amount of illiquid securities may be calculated with reference to a formula the staff of the SEC approves.

Additional risks are involved with options trading because of the low margin deposits required and the extremely high degree of leverage that may be involved in options trading. There may be imperfect correlation between the change in market value of the securities held by the fund and the prices of the options, possible lack of a liquid secondary market, and the resulting inability to close such positions prior to their maturity dates.

The fund may write or purchase an option only when the market value of that option, when aggregated with the market value of all other options transactions made on behalf of the fund, does not exceed 5% of its total assets.

Puts are agreements that allow the buyer to sell a security at a specified price and time to the seller or “put provider.” When the fund buys a security with a put feature, losses could occur if the put provider does not perform as agreed. If a put provider fails to honor its commitment upon the fund’s attempt to exercise the put, the fund may have to treat the security’s final maturity as its effective maturity. If that occurs, the security’s price may be negatively impacted, and its sensitivity to interest rate changes may be increased, possibly contributing to increased share price volatility for the fund. This also could lengthen the fund’s overall average effective maturity. Standby commitments are types of puts.

Spread Transactions may be used for hedging or managing risk. The fund may purchase covered spread options from securities dealers. Such covered spread options are not presently exchange-listed or exchange-traded. The purchase of a spread option gives the fund the right to put, or sell, a security that it owns at a fixed dollar spread or fixed yield spread in relation to another security that the fund does not own, but which is used as a benchmark. The risk to the fund in purchasing covered spread options is the cost of the premium paid for the spread option and any transaction costs. In addition, there is no assurance that closing transactions will be available. The purchase of spread options will be used to protect the fund against adverse changes in prevailing credit quality spreads, i.e ., the yield spread between high quality and lower quality securities. Such protection is only provided during the life of the spread option.

Structured Notes are derivative debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities include structured notes as well as securities other than debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities may include a multiplier that multiplies the indexed element by a specified factor and, therefore, the value of such securities may be very volatile. The terms of the structured and indexed securities may provide that in certain circumstances no principal is due at maturity and therefore, may result in a loss of invested capital. Structured and indexed securities may be positively or negatively indexed, so that appreciation of the reference may produce an increase or a decrease in the interest rate or the value of the structured or indexed security at maturity may be calculated as a specified multiple of the change in the value of the reference; therefore, the value of such security may be very volatile. Structured and indexed securities may entail a greater degree of market risk than other types of debt securities because the investor bears the risk of the reference. Structured or indexed securities may also be more volatile, less liquid, and more difficult to accurately price than less complex securities or more traditional debt securities.

Swap Agreements are privately negotiated over-the-counter derivative products in which two parties agree to exchange payment streams calculated in relation to a rate, index, instrument or certain securities (referred to as the “underlying”) and a predetermined amount (referred to as the “notional amount”). The underlying for a swap may be an interest rate (fixed or floating), a currency exchange rate, a commodity price index, a security, group of securities or a securities index, a combination of any of these, or various other rates, assets or indices. Swap agreements generally do not involve the delivery of the underlying or principal, and a party’s obligations generally are equal to only the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the swap agreement.

Swap agreements can be structured to increase or decrease the fund’s exposure to long or short term interest rates, corporate borrowing rates and other conditions, such as changing security prices and inflation rates. They also can be structured to increase or decrease the fund’s exposure to specific issuers or specific sectors of the bond market such as mortgage securities. For example, if the fund agreed to pay a longer-term fixed rate in exchange for a shorter-term floating rate while holding longer-term fixed rate bonds, the swap would tend to decrease the fund’s exposure to longer-term interest rates. Swap agreements tend to increase or decrease the overall volatility of the fund’s investments and its share price and yield. Changes in interest rates, or other factors determining the amount of payments due to and from the fund, can be the most significant factors in the performance of a swap agreement. If a swap agreement calls for payments from the fund, the fund must be prepared to make such payments when they are due. In order to help minimize risks, the fund will earmark or segregate appropriate assets for any accrued but unpaid net amounts owed under the terms of a swap agreement entered into on a net basis. All other swap agreements will require the fund to earmark or segregate assets in the amount of the accrued amounts owed under the swap. The fund could sustain losses if a counterparty does not perform as agreed under the terms of the swap. The fund will enter into swap agreements with counterparties deemed creditworthy by the investment adviser.

In addition, the fund may invest in swaptions, which are privately-negotiated option-based derivative products. Swaptions give the holder the right to enter into a swap. The fund may use a swaption in addition to or in lieu of a swap involving a similar rate or index.

For purposes of applying the fund’s investment policies and restrictions (as stated in the fund’s prospectus and this SAI), swap agreements are generally valued by the fund at market value. In the case of a credit default swap sold by the fund (i.e., where the fund is selling credit default protection), however, the fund will generally value the swap at its notional amount. The manner in which certain securities or other instruments are valued by the fund for purposes of applying investment policies and restrictions may differ from the manner in which those investments are valued by other types of investors.

Diversification involves investing in a wide range of securities and thereby spreading and reducing the risks of investment. The fund is a series of an open-end investment management company. The fund is a diversified mutual fund. When formed, the fund was sub-classified as a “non-diversified” fund, as defined in the 1940 Act. However, due to the fund’s principal investment strategy and investment process, it has historically operated as a “diversified” fund. Therefore, the fund will not operate in the future as “non-diversified” fund without first obtaining shareholder approval, except as allowed pursuant to the 1940 Act and rules or interpretations thereof.

Emerging or Developing Markets exist in countries that are considered to be in the initial stages of industrialization. The risks of investing in these markets are similar to the risks of international investing in general, although the risks are greater in emerging and developing markets. Countries with emerging or developing securities markets tend to have economic structures that are less stable than countries with developed securities markets. This is because their economies may be based on only a few industries and their securities markets may trade a small number of securities. Prices on these exchanges tend to be volatile, and securities in these countries historically have offered greater potential for gain (as well as loss) than securities of companies located in developed countries.

The fund’s investments in emerging markets can be considered speculative, and therefore may offer higher potential for gains and losses than investments in developed markets of the world. With respect to an emerging country, there may be a greater potential for nationalization, expropriation or confiscatory taxation, political changes, government regulation, social instability or diplomatic developments (including war) which could affect adversely the economies of such countries or investments in such countries. The economies of developing countries generally are heavily dependent upon international trade and, accordingly, have been and may continue to be adversely affected by trade barriers, exchange or currency controls, managed adjustments in relative currency values and other protectionist measures imposed or negotiated by the countries with which they trade.

In addition to the risks of investing in emerging market country debt securities, the fund’s investment in government or government-related securities of emerging market countries and restructured debt instruments in emerging markets are subject to special risks, including the inability or unwillingness to repay principal and interest, requests to reschedule or restructure outstanding debt, and requests to extend additional loan amounts. The fund may have limited recourse in the event of default on such debt instruments.

Exchange Traded Funds (ETFs) such as Standard and Poor’s Depositary Receipts (SPDRs) Trust, are investment companies that typically are registered under the 1940 Act as open-end funds or unit investment trusts (UITs). ETFs are actively traded on national securities exchanges and are generally based on specific domestic and foreign market indices. Shares of an ETF may be bought and sold through the day at market prices, which may be higher or lower than the shares’ net asset value. An “index-based ETF” seeks to track the performance of an index holding in its portfolio either the contents of the index or a representative sample of the securities in the index. Because ETFs are based on an underlying basket of stocks or an index, they are subject to the same market fluctuations as these types of securities in volatile market swings. ETFs, like mutual funds, have expenses associated with their operation, including advisory fees. When the fund invests in an ETF, in addition to directly bearing expenses associated with its own operations, it will bear a pro rata portion of the ETF’s expenses. As with any exchange listed security, ETF shares purchased in the secondary market are subject to customary brokerage fees. Pursuant to an exemptive order issued by the SEC to iShares and procedures approved by the Trust’s Board of Trustees (the “Board”), the fund may invest in iShares not to exceed 25% of the fund’s total assets, provided that the fund has described ETF investments in its prospectus and otherwise complies with the conditions of the exemptive order and other applicable investment limitations.

Equity Securities represent ownership interests in a company, and are commonly called “stocks.” Equity securities historically have outperformed most other securities, although their prices can fluctuate based on changes in a company’s financial condition, market conditions and political, economic or even company-specific news. When a stock’s price declines, its market value is lowered even though the intrinsic value of the company may not have changed. Sometimes factors, such as economic conditions or political events, affect the value of stocks of companies of the same or similar industry or group of industries, and may affect the entire stock market.

Types of equity securities include common stocks, preferred stocks, convertible securities, warrants, rights, ADRs, EDRs, and certain interests in real estate investment trusts. For more information on real estate investment trusts, please see the section entitled “Real Estate Investment Trusts”.

Common stocks , which are probably the most recognized type of equity security, represent an equity or ownership interest in an issuer and usually entitle the owner to voting rights in the election of the corporation’s directors and any other matters submitted to the corporation’s shareholders for voting, as well as to receive dividends on such stock. The market value of common stock can fluctuate widely, as it reflects increases and decreases in an issuer’s earnings. In the event an issuer is liquidated or declares bankruptcy, the claims of bond owners, other debt holders and owners of preferred stock take precedence over the claims of common stock owners. Common stocks are typically categorized by their market capitalization as large-, mid- or small-cap.

Preferred stocks represent an equity or ownership interest in an issuer but do not ordinarily carry voting rights, though they may carry limited voting rights. Preferred stocks normally have preference over the corporation’s assets and earnings, however. For example, preferred stocks have preference over common stock in the payment of dividends. Preferred stocks normally pay dividends at a specified rate. However, preferred stock may be purchased where the issuer has omitted, or is in danger of omitting, payment of its dividend. Such investments would be made primarily for their capital appreciation potential. In the event an issuer is liquidated or declares bankruptcy, the claims of bond owners take precedence over the claims of preferred and common stock owners. Certain classes of preferred stock are convertible into shares of common stock of the issuer. By holding convertible preferred stock, the fund can receive a steady stream of dividends and still have the option to convert the preferred stock to common stock. Preferred stock is subject to many of the same risks as common stock and debt securities.

Convertible securities are typically preferred stocks or bonds that are exchangeable for a specific number of another form of security (usually the issuer’s common stock) at a specified price or ratio. A convertible security generally entitles the holder to receive interest paid or accrued on bonds or the dividend paid on preferred stock until the convertible security matures or is redeemed, converted or exchanged. A corporation may issue a convertible security that is subject to redemption after a specified date, and usually under certain circumstances. A holder of a convertible security that is called for redemption would be required to tender it for redemption to the issuer, convert it to the underlying common stock or sell it to a third party. The convertible structure allows the holder of the convertible bond to participate in share price movements in the company’s common stock. The actual return on a convertible bond may exceed its stated yield if the company’s common stock appreciates in value and the option to convert to common stocks becomes more valuable.

Convertible securities typically pay a lower interest rate than nonconvertible bonds of the same quality and maturity because of the conversion feature. Convertible securities are also rated below investment grade (“high yield”) or are not rated, and are subject to credit risk.

Prior to conversion, convertible securities have characteristics and risks similar to nonconvertible debt and equity securities. In addition, convertible securities are often concentrated in economic sectors, which, like the stock market in general, may experience unpredictable declines in value, as well as periods of poor performance, which may last for several years. There may be a small trading market for a particular convertible security at any given time, which may adversely impact market price and the fund’s ability to liquidate a particular security or respond to an economic event, including deterioration of an issuer’s creditworthiness.

Table of Contents

Convertible preferred stocks are nonvoting equity securities that pay a fixed dividend. These securities have a conversion feature similar to convertible bonds, but do not have a maturity date. Due to their fixed income features, convertible securities provide higher income potential than the issuer’s common stock, but typically are more sensitive to interest rate changes than the underlying common stock. In the event of a company’s liquidation, bondholders have claims on company assets senior to those of shareholders; preferred shareholders have claims senior to those of common shareholders.

Convertible securities typically trade at prices above their conversion value, which is the current market value of the common stock received upon conversion, because of their higher yield potential than the underlying common stock. The difference between the conversion value and the price of a convertible security will vary depending on the value of the underlying common stock and interest rates. When the underlying value of the common stocks declines, the price of the issuer’s convertible securities will tend not to fall as much because the convertible security’s income potential will act as a price support. While the value of a convertible security also tends to rise when the underlying common stock value rises, it will not rise as much because its conversion value is more narrow. The value of convertible securities also is affected by changes in interest rates. For example, when interest rates fall, the value of convertible securities may rise because of their fixed income component.

Rights and Warrants. Rights and warrants are types of securities that entitle the holder to purchase a proportionate amount of common stock at a specified price for a specific period of time. Rights allow a shareholder to buy more shares directly from the company, usually at a price somewhat lower than the current market price of the outstanding shares. Warrants are usually issued with bonds and preferred stock. Rights and warrants can trade on the market separately from the company’s stock. The prices of rights and warrants do not necessarily move parallel to the prices of the underlying common stock. Rights usually expire within a few weeks of issuance, while warrants may not expire for several years. If a right or warrant is not exercised within the specified time period, it will become worthless and the fund will lose the purchase price it paid for the right or warrant and the right to purchase the underlying security.

Initial Public Offering. The fund may purchase shares issued as part of, or a short period after, a company’s initial public offering (“IPOs”), and may at times dispose of those shares shortly after their acquisition. The fund’s purchase of shares issued in IPOs exposes it to the risks associated with companies that have little operating history as public companies, as well as to the risks inherent in those sectors of the market where these new issuers operate. The market for IPO issuers has been volatile, and share prices of newly-public companies have fluctuated significantly over short periods of time.

Master Limited Partnerships (“MLPs”). MLPs are limited partnerships in which the common units are publicly traded. MLP common units are freely traded on a securities exchange or in the over-the-counter market and are generally registered with the SEC. MLPs often own several properties or businesses (or own interests) that are related to real estate development and oil and gas industries, but they also may finance motion pictures, research and development and other projects. MLPs generally have two classes of owners, the general partner and limited partners. The general partner is typically owned by a major energy company, an investment fund, the direct management of the MLP or is an entity owned by one or more of such parties. The general partner may be structured as a private or publicly traded corporation or other entity. The general partner typically controls the operations and management of the MLP through an up to 2% equity interest in the MLP plus, in many cases, ownership of common units and subordinated units. Limited partners own the remainder of the partnership, through ownership of common units, and have a limited role, if any, in the partnership’s operations and management.

MLPs are typically structured such that common units and general partner interests have first priority to receive quarterly cash distributions up to an established minimum amount (“minimum quarterly distributions”). Common and general partner interests also accrue arrearages in distributions to the extent the minimum quarterly distribution is not paid. Once common and general partner interests have been paid, subordinated units receive distributions of up to the minimum quarterly distribution; however,

21

Table of Contents

subordinated units do not accrue arrearages. Distributable cash in excess of the minimum quarterly distribution paid to both common and subordinated units is distributed to both common and subordinated units generally on a pro rata basis. The general partner is also eligible to receive incentive distributions if the general partner operates the business in a manner which results in distributions paid per common unit surpassing specified target levels. As the general partner increases cash distributions to the limited partners, the general partner receives an increasingly higher percentage of the incremental cash distributions. A common arrangement provides that the general partner can reach a tier where it receives 50% of every incremental dollar paid to common and subordinated unit holders. These incentive distributions are intended to encourage the general partner to streamline costs, increase capital expenditures and acquire assets in order to increase the partnership’s cash flow and raise the quarterly cash distribution in order to reach higher tiers. Such results are intended to benefit all security holders of the MLP, however, such incentive distribution payments give rise to potential conflicts of interest between the common unit holders and the general partner.

MLP common units represent a limited partnership interest in the MLP. Common units are listed and traded on U.S. securities exchanges or over-the-counter, with their value fluctuating predominantly based on prevailing market conditions and the success of the MLP. The fund may purchase common units in market transactions as well as directly from the MLP or other parties in private placements. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability to annually elect directors. MLPs generally distribute all available cash flow (cash flow from operations less maintenance capital expenditures) in the form of quarterly distributions. Common units along with general partner units, have first priority to receive quarterly cash distributions up to the minimum quarterly distribution and have arrearage rights. In the event of liquidation, common units have preference over subordinated units, but not debt or preferred units, to the remaining assets of the MLP.

MLP subordinated units are typically issued by MLPs to their original sponsors, such as their founders, corporate general partners of MLPs, entities that sell assets to the MLP, and investors. Subordinated units may be purchased directly from these persons as well as newly-issued subordinated units from MLPs themselves. Subordinated units have similar voting rights as common units and are generally not publicly traded. Once the minimum quarterly distribution on the common units, including any arrearages, has been paid, subordinated units receive cash distributions up to the minimum quarterly distribution prior to any incentive payments to the MLP’s general partner. Unlike common units, subordinated units do not have arrearage rights. In the event of liquidation, common units and general partner interests have priority over subordinated units. Subordinated units are typically converted into common units on a one-to-one basis after certain time periods and/or performance targets have been satisfied. The purchase or sale price of subordinated units is generally tied to the common unit price less a discount. The size of the discount varies depending on the likelihood of conversion, the length of time remaining to conversion, the size of the block purchased relative to trading volumes, and other factors, including smaller capitalization partnerships or companies potentially having limited product lines, markets or financial resources, lacking management depth or experience, and being more vulnerable to adverse general market or economic development than larger more established companies.

General partner interests of MLPs are typically retained by an MLP’s original sponsors, such as its founders, corporate partners, entities that sell assets to the MLP and investors. A holder of general partner interests can be liable under certain circumstances for amounts greater than the amount of the holder’s investment in the general partner interest. General partner interests often confer direct board participation rights and in many cases, operating control, over the MLP. These interests themselves are not publicly traded, although they may be owned by publicly traded entities. General partner interests receive cash distributions, typically 2% of the MLP’s aggregate cash distributions, which are contractually defined in the partnership agreement. In addition, holders of general partner interests typically hold incentive distribution rights, which provide them with a larger share of the aggregate MLP cash distributions as the distributions to limited partner unit holders are increased to prescribed levels. General partner interests generally cannot be converted into common units. The general partner interest can be redeemed by the MLP if the MLP unitholders choose to remove the general partner, typically with a supermajority vote by limited partner unitholders.

Additional risks involved with investing in an MLP are risks associated with the specific industry or industries in which the partnership invests, such as the risks of investing in real estate, or oil and gas industries.

Certain MLPs are dependent on their parent companies or sponsors for a majority of their revenues. Any failure by an MLP’s parents or sponsors to satisfy their payments or obligations would impact the MLP’s revenues and cash flows and ability to make distributions.

Small-Cap Stocks include common stocks issued by operating companies with market capitalizations that place them at the lower end of the stock market, as well as the stocks of companies that are determined to be small based on several factors, including the capitalization of the company and the amount of revenues. Historically, small-cap company stocks have been riskier than stocks issued by large- or mid-cap companies for a variety of reasons. Small-cap companies may have less certain growth prospects and are typically less diversified and less able to withstand changing economic conditions than larger capitalized companies. Small-cap companies also may have more limited product lines, markets or financial resources than companies with larger capitalizations, and may be more dependent on a relatively small management group. In addition, small-cap companies may not be well known to the investing public, may not have institutional ownership and may have only cyclical, static or moderate growth prospects. Most small-cap company stocks pay low or no dividends.

These factors and others may cause sharp changes in the value of a small-cap company’s stock, and even cause some small-cap companies to fail. Additionally, small-cap stocks may not be as broadly traded as large- or mid-cap stocks, and a fund’s positions in securities of such companies may be substantial in relation to the market for such securities. Accordingly, it may be difficult for a fund to dispose of securities of these small-cap companies at prevailing market prices in order to meet redemptions. This lower degree of liquidity can adversely affect the value of these securities. For these reasons and others, the value of a fund’s investments in small-cap stocks is expected to be more volatile than other types of investments, including other types of stock investments. While small-cap stocks are generally considered to offer greater growth opportunities for investors, they involve greater risks and the share price of a fund that invests in small-cap stocks may change sharply during the short term and long term.

Foreign Currency Transactions . The fund may invest in foreign currency-denominated securities, purchase and sell foreign currency options and foreign currency futures contracts and related options and engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time or through forward currency contracts (“forwards”) with terms generally of less than one year. The fund may engage in these transactions in order to protect against uncertainty in the level of future foreign exchange rates in the purchase and sale of securities.

The fund may, but is not required to, use foreign currency options and foreign currency forward contracts to increase exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. The fund will earmark or segregate assets for any open positions in forwards used for non-hedging purposes and mark to market daily as may be required under the federal securities laws.

A forward involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts may be bought or sold to protect the fund against a possible loss resulting from an adverse change in the relationship between foreign currencies and the U.S. dollar or to

23

Table of Contents

increase exposure to a particular foreign currency. Many foreign securities markets do not settle trades within a time frame that would be considered customary in the U.S. stock market. Therefore, the fund may engage in forward foreign currency exchange contracts in order to secure exchange rates for fund securities purchased or sold, but awaiting settlement. These transactions do not seek to eliminate any fluctuations in the underlying prices of the securities involved. Instead, the transactions simply establish a rate of exchange that can be expected when the fund settles its securities transactions in the future. Forwards involve certain risks. For example, if the counterparties to the contracts are unable to meet the terms of the contracts or if the value of the foreign currency changes unfavorably, the fund could sustain a loss.

The fund may also engage in forward foreign currency exchange contracts to protect the value of specific portfolio positions, which is called “position hedging.” When engaging in position hedging, the fund may enter into forward foreign currency exchange transactions to protect against a decline in the values of the foreign currencies in which portfolio securities are denominated (or against an increase in the value of currency for securities the fund expects to purchase).

Buying and selling foreign currency exchange contracts involves costs and may result in losses. The ability of the fund to engage in these transactions may be limited by tax considerations. Although these techniques tend to minimize the risk of loss due to declines in the value of the hedged currency, they tend to limit any potential gain that might result from an increase in the value of such currency. Transactions in these contracts involve certain other risks. Unanticipated fluctuations in currency prices may result in a poorer overall performance for the fund than if it had not engaged in any such transactions. Moreover, there may be imperfect correlation between the fund’s holdings of securities denominated in a particular currency and forward contracts into which the fund enters. Such imperfect correlation may cause the fund to sustain losses, which will prevent it from achieving a complete hedge or expose it to risk of foreign exchange loss.

Suitable hedging transactions may not be available in all circumstances and there can be no assurance that the fund will engage in such transactions at any given time or from time to time. Also, such transactions may not be successful and may eliminate any chance for the fund to benefit from favorable fluctuations in relevant foreign currencies. Forwards will be used primarily to adjust the foreign exchange exposure of the fund with a view to protecting the outlook, and the fund might be expected to enter into such contracts under the following circumstances:

Lock In: When the investment adviser desires to lock in the U.S. dollar price on the purchase or sale of a security denominated in a foreign currency.

Cross Hedge: If a particular currency is expected to decrease against another currency, the fund may sell the currency expected to decrease and purchase the other currency expected to increase against the currency sold in an amount approximately equal to some or all of the fund’s portfolio holdings denominated in the currency sold.

Direct Hedge: If the investment adviser wants to eliminate substantially all of the risk of owning a particular currency, and/or if the investment adviser thinks that the fund can benefit from price appreciation in a given country’s bonds but does not want to hold the currency, it may employ a direct hedge back into the U.S. dollar. In either case, the fund would enter into a forward contract to sell the currency in which a portfolio security is denominated and purchase U.S. dollars at an exchange rate established at the time it initiated the contract. The cost of the direct hedge transaction may offset most, if not all, of the yield advantage offered by the foreign security, but the fund would benefit from an increase in value of the bond.

24

Table of Contents

Proxy Hedge: The investment adviser might choose to use a proxy hedge, which may be less costly than a direct hedge. In this case, the fund, having purchased a security, will sell a currency whose value is believed to be closely linked to the currency in which the security is denominated. Interest rates prevailing in the country whose currency was sold would be expected to be closer to those in the U.S. and lower than those of securities denominated in the currency of the original holding. This type of hedging entails greater risk than a direct hedge because it is dependent on a stable relationship between the two currencies paired as proxies and the relationships can be very unstable at times.

Costs of Hedging: When the fund purchases a foreign bond with a higher interest rate than is available on U.S. bonds of a similar maturity, the additional yield on the foreign bond could be substantially reduced or lost if the fund were to enter into a direct hedge by selling the foreign currency and purchasing the U.S. dollar. This is what is known as the “cost” of hedging. Proxy hedging attempts to reduce this cost through an indirect hedge back to the U.S. dollar. It is important to note that hedging costs are treated as capital transactions and are not, therefore, deducted from the fund’s dividend distribution and are not reflected in its yield. Instead such costs will, over time, be reflected in the fund’s net asset value per share.

Tax Consequences of Hedging. Under applicable tax law, the fund may be required to limit its gains from hedging in foreign currency forwards, futures, and options. Although the fund is expected to comply with such limits, the extent to which these limits apply is subject to tax regulations as yet unissued. Hedging may also result in the application of the mark-to-market and straddle provisions of the Internal Revenue Code of 1986, as amended (“Internal Revenue Code”). Those provisions could result in an increase (or decrease) in the amount of taxable dividends paid by the fund and could affect whether dividends paid by the fund are classified as capital gains or ordinary income.

Foreign Securities involve additional risks. The fund may invest in U.S. dollar-denominated securities issued by foreign institutions or securities that are subject to credit or liquidity enhancements provided by foreign institutions. Foreign institutions may not be subject to uniform accounting, auditing and financial reporting standards, practices and requirements that are comparable to those applicable to U.S. corporations. In addition, there may be less publicly available information about foreign entities. Foreign economic, political and legal developments could have effects on the value of the foreign securities issued or supported by foreign institutions. For example, conditions within and around foreign countries, such as the possibility of expropriation or confiscatory taxation, political or social instability, diplomatic developments, change of government or war could affect the value of these securities. In addition, there may be difficulties in obtaining or enforcing judgments against the foreign institutions that issue or support securities in which the fund may invest. These factors and others may increase the risks with respect to the liquidity of the fund, and its ability to meet a large number of shareholder redemption requests.

Financial markets in the eurozone have experienced volatility over the past few years due, in part, to concerns about rising levels of government debt and the prevalence of increased budget deficits. Delays by politicians and regulators to address structural and policy issues in the eurozone have added to instability in the region. The implementation of austerity measures in Spain, Italy, Greece, Portugal and Ireland at a time when the eurozone is experiencing higher unemployment and slowing economic activity has raised the possibility of a prolonged recession in the region. However, recent policy actions by leaders of the European Union (“EU”) and the European Central Bank have significantly reduced the possibility of a default by a eurozone government and have reduced market volatility.

The severity and prolonged nature of the eurozone crisis caused certain individuals and institutions to question the continued viability of the euro as a unit of currency. It is possible individual EU member countries that have already adopted the euro may abandon that currency and revert to a national currency or otherwise exit the EU. It is also possible that the euro will cease to exist as a single unit of currency in

25

its current form. The precise effects of any such outcome on regional or global financial markets are impossible to predict. However, the abandonment of the euro or the exit of any country out of the EU would likely have an extremely destabilizing effect on all EU member countries and their economies, which would likely impact the global economy.

As the fund may hold certain investments of issuers located in the eurozone, any material negative developments in the region could have a negative impact on the investments held by the fund, which could hurt their overall performance.

Illiquid Securities generally are any securities that cannot be disposed of promptly and in the ordinary course of business at approximately the amount at which the fund has valued the instruments. The liquidity of the fund’s investments is monitored under the supervision and direction of the Board of Trustees. Investments currently considered illiquid include, among others, repurchase agreements not maturing within seven days and certain restricted securities.

Interfund Borrowing and Lending. The SEC has granted an exemption to the Schwab Funds that permits the funds to borrow money from and/or lend money to other Schwab Funds. All loans are for temporary or emergency purposes and the interest rates to be charged will be the average of the overnight repurchase agreement rate and the short-term bank loan rate. All loans are subject to numerous conditions designed to ensure fair and equitable treatment of all participating funds/portfolios. The interfund lending facility is subject to the oversight and periodic review of the board of trustees of each Schwab Fund.

Money Market Securities are high-quality, short-term debt securities that may be issued by entities such as the U.S. government, corporations and financial institutions (like banks). Money market securities include commercial paper, certificates of deposit, bankers’ acceptances, notes and time deposits.

Money market securities pay fixed, variable or floating rates of interest and are generally subject to credit and interest rate risks. The maturity date or price of and financial assets collateralizing a security may be structured in order to make it qualify as or act like a money market security. These securities may be subject to greater credit and interest rate risks than other money market securities because of their structure. Money market securities may be issued with puts or sold separately, sometimes called demand features or guarantees, which are agreements that allow the buyer to sell a security at a specified price and time to the seller or “put provider.” When the fund buys a put, losses could occur as a result of the costs of the put or if it exercises its rights under the put and the put provider does not perform as agreed. Standby commitments are types of puts.

The fund must keep a portion of its assets in cash for business operations. In order to reduce the effect this otherwise uninvested cash would have on its performance, the fund may invest in money market securities.

Bankers’ Acceptances or Notes are credit instruments evidencing a bank’s obligation to pay a draft drawn on it by a customer. These instruments reflect the obligation both of the bank and of the drawer to pay the full amount of the instrument upon maturity. The fund will invest only in bankers’ acceptances of banks that have capital, surplus and undivided profits in the aggregate in excess of $100 million.

Certificates of Deposit or Time Deposits are issued against funds deposited in a banking institution for a specified period of time at a specified interest rate. The fund will invest only in certificates of deposit of banks that have capital, surplus and undivided profits in the aggregate in excess of $100 million.

Commercial Paper consists of short-term, promissory notes issued by banks, corporations and other institutions to finance short-term credit needs. These securities generally are discounted but sometimes may be interest bearing. Commercial paper, which also may be unsecured, is subject to credit risk.

Fixed Time Deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties, which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits. The fund will not invest in fixed time deposits, which (1) are not subject to prepayment or (2) provide for withdrawal penalties upon prepayment (other than overnight deposits) if, in the aggregate, more than 15% of its net assets would be invested in such deposits, repurchase agreements maturing in more than seven days and other illiquid assets.

Promissory Notes are written agreements committing the maker or issuer to pay the payee a specified amount either on demand or at a fixed date in the future, with or without interest. These are sometimes called negotiable notes or instruments and are subject to credit risk. Bank notes are notes used to represent obligations issued by banks in large denominations.

Repurchase Agreements are instruments under which a buyer acquires ownership of certain securities (usually U.S. government securities) from a seller who agrees to repurchase the securities at a mutually agreed-upon time and price, thereby determining the yield during the buyer’s holding period. Any repurchase agreements a fund enters into will involve the fund as the buyer and banks or broker-dealers as sellers. The period of repurchase agreements is usually short - from overnight to one week, although the securities collateralizing a repurchase agreement may have longer maturity dates. Default by the seller might cause a fund to experience a loss or delay in the liquidation of the collateral securing the repurchase agreement. The fund also may incur disposition costs in liquidating the collateral. In the event of a bankruptcy or other default of a repurchase agreement’s seller, a fund might incur expenses in enforcing its rights, and could experience losses, including a decline in the value of the underlying securities and loss of income. The fund will make payment under a repurchase agreement only upon physical delivery or evidence of book entry transfer of the collateral to the account of its custodian bank.

Mortgage-Backed Securities and other Asset-Backed Securities may be purchased by the fund. MBS represent participations in mortgage loans, and include pass-through securities, collateralized mortgage obligations and stripped mortgage-backed securities. MBS may be issued or guaranteed by U.S. government agencies or instrumentalities, such as the Government National Mortgage Association (“GNMA” or “Ginnie Mae”) and the Federal National Mortgage Association (“FNMA” or “Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”).

The National Housing Act authorized GNMA to guarantee the timely payment of principal and interest on securities backed by a pool of mortgages insured by the Federal Housing Administration (“FHA”) or guaranteed by the Veterans Administration (“VA”). The GNMA guarantee is backed by the full faith and credit of the U.S. government. The GNMA is also empowered to borrow without limitation from the U.S. Treasury if necessary to make any payments required under its guarantee.

GNMA are mortgage securities which evidence an undivided interest in a pool or pools of mortgages. GNMA Certificates that the fund may purchase are the “modified pass-through” type, which entitle the holder to receive timely payment of all interest and principal payments due on the mortgage pool, net of fees paid to the “issuer” and GNMA, regardless of whether or not the mortgagor actually makes the payment.

27

Table of Contents

The average life of a GNMA Certificate is likely to be substantially shorter than the original maturity of the mortgages underlying the securities. Prepayments of principal by mortgagors and mortgage foreclosures will usually result in the return of the greater part of principal investment long before the maturity of the mortgages in the pool. Foreclosures impose no risk to principal investment because of the GNMA guarantee, except to the extent that the fund has purchased the certificates above par in the secondary market.

FHLMC was created in 1970 to promote development of a nationwide secondary market in conventional residential mortgages. The FHLMC issues two types of mortgage pass-through securities (“FHLMC Certificates”): mortgage participation certificates (“PCs”) and guaranteed mortgage certificates (“GMCs”). PCs resemble GNMA Certificates in that each PC represents a pro rata share of all interest and principal payments made and owed on the underlying pool. The FHLMC guarantees timely monthly payment of interest on PCs and the ultimate payment of principal, but its issues are not backed by the full faith and credit of the U.S. government.

GMCs also represent a pro rata interest in a pool of mortgages. However, these instruments pay interest semi-annually and return principal once a year in guaranteed minimum payments. The expected average life of these securities is approximately 10 years. The FHLMC guarantee is not backed by the full faith and credit of the U.S. government.

FNMA was established in 1938 to create a secondary market in mortgages the FHA insures. FNMA issues guaranteed mortgage pass-through certificates (“FNMA Certificates”). FNMA Certificates resemble GNMA Certificates in that each FNMA Certificate represents a pro rata share of all interest and principal payments made and owed on the underlying pool. FNMA guarantees timely payment of interest and principal on FNMA Certificates. The FNMA guarantee is not backed by the full faith and credit of the U.S. government.

MBS may also be issued by private issuers, generally originators and investors in mortgage loans, including savings associations, mortgage banks, commercial banks, and special purpose entities (collectively, “private lenders”). MBS are based on different types of mortgages including those on commercial real estate and residential property. MBS issued by private lenders may be supported by pools of mortgage loans or other MBS that are guaranteed, directly or indirectly, by the U.S. government or one of its agencies or instrumentalities, or they may be issued without any governmental guarantee of the underlying mortgage assets but with some form of credit enhancement.

Asset-backed Securities (“ABS”) have structural characteristics similar to MBS. ABS represent direct or indirect participation in assets such as automobile loans, credit card receivables, trade receivables, home equity loans (which sometimes are categorized as MBS) or other financial assets. Therefore, repayment depends largely on the cash flows generated by the assets backing the securities. The credit quality of most ABS depends primarily on the credit quality of the assets underlying such securities, how well the entity issuing the security is insulated from the credit risk of the originator or any other affiliated entities, and the amount and quality of any credit enhancement of the securities. Payments or distributions of principal and interest on ABS may be supported by credit enhancements including letters of credit, an insurance guarantee, reserve funds and overcollateralization. Asset-backed securities also may be debt instruments, which are also known as collateralized obligations and are generally issued as the debt of a special purpose entity, such as a trust, organized solely for the purpose of owning such assets and issuing debt obligations.

Collateralized Debt Obligations. The fund may invest in collateralized debt obligations (“CDOs”), which include collateralized bond obligations (“CBOs”), collateralized loan obligations (“CLOs”) and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust that is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans.

28

Table of Contents

For both CBOs and CLOs, the cash flows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the “equity” tranche which bears the bulk of defaults from the bonds or loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Since it is partially protected from defaults, a senior tranche from a CBO trust or CLO trust typically has higher ratings and lower yields than their underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults, as well as aversion to CBO or CLO securities as a class.

The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which the fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus, are not registered under the securities laws. As a result, investments in CDOs may be characterized by the fund as illiquid securities, however an active dealer market may exist for CDOs allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed income securities discussed elsewhere in this SAI and the fund’s prospectus ( e.g., interest rate risk and default risk), CDOs carry additional risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or default; (iii) the fund may invest in CDOs that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Commercial Mortgage-Backed Securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. The market for commercial mortgage-backed securities developed more recently and in terms of total outstanding principal amount of issues is relatively small compared to the market for residential single-family MBS. Many of the risks of investing in commercial MBS reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial MBS may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities.

Collateralized Mortgage Obligations (“CMO”) are a hybrid between mortgage-backed bonds and mortgage pass-through securities. Similar to a bond, interest and prepaid principal is paid, in most cases, on a monthly basis. CMOs may be collateralized by whole mortgage loans, but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by Ginnie Mae, Freddie Mac, Fannie Mae, and their income streams as well as private issuers.

CMOs are structured into multiple classes, each bearing a different stated maturity. Actual maturity and average life will depend upon the prepayment experience of the collateral. CMOs provide for a modified form of call protection through a de facto breakdown of the underlying pool of mortgages according to how quickly the loans are repaid. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes receive principal only after the first class has been retired. An investor is partially guarded against a sooner than desired return of principal because of the sequential payments.

29

Table of Contents

In a typical CMO transaction, a corporation (“issuer”) issues multiple series ( e.g. , A, B, C, Z) of CMO bonds (“Bonds”). Proceeds of the Bond offering are used to purchase mortgages or mortgage pass-through certificates (“Collateral”). The Collateral is pledged to a third party trustee as security for the Bonds. Principal and interest payments from the Collateral are used to pay principal on the Bonds in the order A, B, C, Z. The Series A, B, and C Bonds all bear current interest. Interest on the Series Z Bond is accrued and added to principal and a like amount is paid as principal on the Series A, B, or C Bond currently being paid off. When the Series A, B, and C Bonds are paid in full, interest and principal on the Series Z Bond begins to be paid currently. With some CMOs, the issuer serves as a conduit to allow loan originators (primarily builders or savings and loan associations) to borrow against their loan portfolios.

The rate of principal payment on MBS and ABS generally depends on the rate of principal payments received on the underlying assets which in turn may be affected by a variety of economic and other factors. As a result, the price and yield on any MBS or ABS is difficult to predict with precision and price and yield to maturity may be more or less than the anticipated yield to maturity. If the fund purchases these securities at a premium, a prepayment rate that is faster than expected will reduce yield to maturity, while a prepayment rate that is slower than expected will have the opposite effect of increasing the yield to maturity. Conversely, if the fund purchases these securities at a discount, a prepayment rate that is faster than expected will increase yield to maturity, while a prepayment rate that is slower than expected will reduce yield to maturity. Amounts available for reinvestment by the fund are likely to be greater during a period of declining interest rates and, as a result, are likely to be reinvested at lower interest rates than during a period of rising interest rates.

While many MBS and ABS are issued with only one class of security, many are issued in more than one class, each with different payment terms. Multiple class MBS and ABS are issued as a method of providing credit support, typically through creation of one or more classes whose right to payments on the security is made subordinate to the right to such payments of the remaining class or classes. In addition, multiple classes may permit the issuance of securities with payment terms, interest rates, or other characteristics differing both from those of each other and from those of the underlying assets. Examples include stripped securities, which are MBS and ABS entitling the holder to disproportionate interest or principal compared with the assets backing the security, and securities with classes having characteristics different from the assets backing the securities, such as a security with floating interest rates with assets backing the securities having fixed interest rates. The market value of such securities and CMO’s generally is more or less sensitive to changes in prepayment and interest rates than is the case with traditional MBS and ABS, and in some cases such market value may be extremely volatile.

CMO Residuals are mortgage securities issued by agencies or instrumentalities of the U.S. government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks and special purpose entities of the foregoing.

The cash flow generated by the mortgage assets underlying a series of CMOs is applied first to make required payments of principal and interest on the CMOs and second to pay the related administrative expenses of the issuer. The residual in a CMO structure generally represents the interest in any excess cash flow remaining after making the foregoing payments. Each payment of such excess cash flow to a holder of the related CMO residual represents income and/or a return of capital. The amount of residual cash flow resulting from a CMO will depend on, among other things, the characteristics of the mortgage assets, the coupon rate of each class of CMO, prevailing interest rates, the amount of administrative expenses and the prepayment experience on the mortgage assets. In particular, the yield to maturity on CMO residuals is extremely sensitive to prepayments on the related underlying mortgage assets, in the same manner as an interest-only (“IO”) class of stripped mortgage-backed securities. See “Stripped Mortgage-Backed Securities.” In addition, if a series of a CMO includes a class that bears interest at an

30

Table of Contents

adjustable rate, the yield to maturity on the related CMO residual will also be extremely sensitive to changes in the level of the index upon which interest rate adjustments are based. As described below with respect to stripped mortgage-backed securities, in certain circumstances the fund may fail to recoup fully its initial investment in a CMO residual.

CMO residuals are generally purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. The CMO residual market has only very recently developed and CMO residuals currently may not have the liquidity of other more established securities trading in other markets. Transactions in CMO residuals are generally completed only after careful review of the characteristics of the securities in question. In addition, CMO residuals may, or pursuant to an exemption therefrom, may not have been registered under the Securities Act of 1933, as amended (the “1933 Act”). CMO residuals, whether or not registered under the 1933 Act, may be subject to certain restrictions on transferability, and may be deemed “illiquid” and subject to the fund’s limitations on investment in illiquid securities.

Stripped Mortgage-Backed Securities (“SMBS”) are derivative multi-class mortgage securities. SMBS may be issued by agencies or instrumentalities of the U.S. government, or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks and special purpose entities of the foregoing.

SMBS are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest (the “IO” class), while the other class will receive all of the principal (the principal-only or “PO” class). The yield to maturity on an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on the fund’s yield to maturity from these securities. If the underlying mortgage assets experience greater than anticipated prepayments of principal, the fund may fail to recoup some or all of its initial investment in these securities even if the security is in one of the highest rating categories.

Under certain circumstances these securities may be deemed “illiquid” and subject to the fund’s limitations on investment in illiquid securities.

Non-Publicly Traded Securities and Private Placements are securities that are neither listed on a stock exchange nor traded over-the-counter, including privately placed securities. Such unlisted securities may involve a higher degree of business and financial risk that can result in substantial losses. As a result of the absence of a public trading market for these securities, they may be less liquid than publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid by the fund or less than what may be considered the fair value of such securities. Furthermore, companies whose securities are not publicly traded may not be subject to the disclosure and other investor protection requirements which might be applicable if their securities were publicly traded. If such securities are required to be registered under the securities laws of one or more jurisdictions before being sold, the fund may be required to bear the expenses of registration.

Real Estate Investments. The fund invests in securities of real estate companies and other companies related to the real estate industry. Real estate companies include U.S. and non-U.S. issuers that in the opinion of the adviser derive at least 50% of their revenues or profits from the ownership, construction, development, financing, management, servicing, sale or leasing of commercial, industrial or residential

31

Table of Contents

real estate or have 50% of their total assets in real estate. Companies related to the real estate industry include companies whose products and services pertain to the real estate industry, such as mortgage lenders and mortgage servicing companies. The fund may invest a significant portion of its assets in real estate investment trusts (“REITs”) (which are more fully discussed below) and in real estate operating companies (“REOCs”).

REOCs are corporations that engage in the ownership, development, management or financing of real estate. They include, for example, developers, brokers and building suppliers. REOCs are publicly traded real estate companies that have chosen not to be taxed as REITs. Because REOCs reinvest earnings rather than distribute dividends to unit holders, they do not get the same benefits of lower corporate taxation that are a common characteristic of REITs. The value of the fund’s REOC securities generally will be affected by the same factors that adversely affect a REIT.

Although the fund may not invest directly in real estate, concentration in securities of companies that are principally engaged in the real estate industry exposes the fund to special risks associated with the direct ownership of real estate, and an investment in the fund will be closely linked to the performance of the real estate markets. These risks may include, but are not limited to, the following: declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage funds; lack of ability to access the credit or capital markets; overbuilding; extended vacancies of properties; defaults by borrowers or tenants, particularly during an economic downturn; increasing 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 market and sub-market values and the appeal of properties to tenants; and changes in interest rates.

REITs are pooled investment vehicles, which invest primarily in income producing real estate or real estate related loans or interests and, in some cases, manage real estate. REITs are sometimes referred to as equity REITs, mortgage REITs or hybrid REITs. An equity REIT invests primarily in properties and generates income from rental and lease properties and, in some cases, from the management of real estate. Equity REITs also offer the potential for growth as a result of property appreciation and from the sale of appreciated property. Mortgage REITs invest primarily in real estate mortgages, which may secure construction, development or long-term loans, and derive income for the collection of interest payments. Hybrid REITs may combine the features of equity REITs and mortgage REITs. REITs are generally organized as corporations or business trusts, but are not taxed as a corporation if they meet certain requirements of Subchapter M of the Internal Revenue Code. To qualify, a REIT must, among other things, invest substantially all of its assets in interests in real estate (including other REITs), cash and government securities, distribute at least 90% of its taxable income to its shareholders and receive at least 75% of that income from rents, mortgages and sales of property. The fund may also invest in REIT-like structures adopted by foreign countries.

Like any investment in real estate, a REIT’s performance depends on many factors, such as its ability to find tenants for its properties, to renew leases, and to finance property purchases and renovations. In general, REITs may be affected by changes in underlying real estate values, which may have an exaggerated effect to the extent a REIT concentrates its investment in certain regions or property types. For example, rental income could decline because of extended vacancies, increased competition from nearby properties, tenants’ failure to pay rent, or incompetent management. Property values could decrease because of overbuilding, environmental liabilities, uninsured damages caused by natural disasters, a general decline in the neighborhood, losses due to casualty or condemnation, increases in property taxes, or changes in zoning laws. Ultimately, a REIT’s performance depends on the types of properties it owns and how well the REIT manages its properties.

Table of Contents

In general, during periods of rising interest rates, REITs may lose some of their appeal for investors who may be able to obtain higher yields from other income-producing investments, such as long term bonds. Higher interest rates also mean that financing for property purchases and improvements is more costly and difficult to obtain. During periods of declining interest rates, certain mortgage REITs may hold mortgages that mortgagors elect to prepay, which can reduce the yield on securities issued by mortgage REITs. Mortgage REITs may be affected by the ability of borrowers to repay debts to the REIT when due and equity REITs may be affected by the ability of tenants to pay rent.

Like small-cap stocks in general, certain REITs have relatively small market capitalizations and their securities can be more volatile than—and at times will perform differently from—large-cap stocks. In addition, because small-cap stocks are typically less liquid than large-cap stocks, REIT stocks may sometimes experience greater share-price fluctuations than the stocks of larger companies. Further, REITs are dependent upon specialized management skills, have limited diversification, and are therefore subject to risks inherent in operating and financing a limited number of projects. By investing in REITs indirectly through the fund, a shareholder will bear indirectly a proportionate share of the REIT’s expenses in addition to their proportionate share of the fund’s expenses. Finally, REITs could possibly fail to qualify for tax-free pass-through of income under the Code or to maintain their exemptions from registration under the 1940 Act and CFTC regulations.

Restricted Securities are securities that are subject to legal restrictions on their sale. Difficulty in selling restricted securities may result in a loss or be costly to a fund. Restricted securities generally can be sold in privately negotiated transactions, pursuant to an exemption from registration under the 1933 Act, or in a registered public offering. Where registration is required, the holder of a registered security may be obligated to pay all or part of the registration expense and a considerable period may elapse between the time it decides to seek registration and the time it may be permitted to sell a security under an effective registration statement. If, during such a period, adverse market conditions were to develop, the holder might obtain a less favorable price than prevailed when it decided to seek registration of the security. Certain restricted securities, such as 4(2) commercial paper and Rule 144A securities, may be considered to be liquid if they meet the criteria for liquidity established by the Board. To the extent the fund invests in restricted securities that are deemed liquid, the general level of illiquidity in the fund’s portfolio may be increased if such securities become illiquid.

Securities Lending of portfolio securities is a common practice in the securities industry. The fund may engage in security lending arrangements with the primary objective of increasing its income. For example, the fund may receive cash collateral and may invest it in short-term, interest-bearing obligations, but will do so only to the extent that it will not lose the tax treatment available to regulated investment companies. Lending portfolio securities involves risks that the borrower may fail to return the securities or provide additional collateral. Also, voting rights with respect to the loaned securities may pass with the lending of the securities.

The fund may loan portfolio securities to qualified broker-dealers or other institutional investors provided: (1) the loan is secured continuously by collateral consisting of U.S. government securities, letters of credit, cash or cash-equivalents or other appropriate instruments maintained on a daily marked-to-market basis in an amount at least equal to the current market value of the securities loaned; (2) the fund may at any time call the loan and obtain the return of the securities loaned; (3) the fund will receive any interest or dividends paid on the loaned securities; and (4) an aggregate market value of securities loaned will not at any time exceed one-third of the total assets of the fund, including collateral received from the loan (at market value computed at the time of the loan).

Although voting rights with respect to loaned securities pass to the borrower, the lender retains the right to recall a security (or terminate a loan) for the purpose of exercising the security’s voting rights. Efforts to recall such securities promptly may be unsuccessful, especially for foreign securities or thinly traded securities such as small-cap stocks. In addition, because recalling a security may involve expenses to the fund, it is expected that the fund will do so only where the items being voted upon are, in the judgment of the investment adviser, either material to the economic value of the security or threaten to materially impact the issuer’s corporate governance policies or structure.

Securities of Other Investment Companies and those issued by foreign investment companies may be purchased and sold by the fund. Mutual funds are registered investment companies, which may issue and redeem their shares on a continuous basis (open-end mutual funds) or may offer a fixed number of shares usually listed on an exchange (closed-end mutual funds). Mutual funds generally offer investors the advantages of diversification and professional investment management, by combining shareholders’ money and investing it in various types of securities, such as stocks, bonds and money market securities. Mutual funds also make various investments and use certain techniques in order to enhance their performance. These may include entering into delayed-delivery and when-issued securities transactions or swap agreements, buying and selling futures contracts, illiquid and restricted securities and repurchase agreements and borrowing or lending money and/or portfolio securities. The risks of investing in mutual funds generally reflect the risks of the securities in which the mutual funds invest and the investment techniques they may employ. Also, mutual funds charge fees and incur operating expenses.

If the fund decides to purchase securities of other investment companies, the fund intends to purchase shares of mutual funds in compliance with the requirements of federal law or any applicable exemptive relief received from the SEC. Mutual fund investments for the fund are currently restricted under federal regulations, and therefore, the extent to which the fund may invest in another mutual fund may be limited.

Funds in which the fund also may invest include unregistered or privately-placed funds, such as hedge funds and off-shore funds, and unit investment trusts. Hedge funds and off-shore funds are not registered with the SEC, and therefore are largely exempt from the regulatory requirements that apply to registered investment companies (mutual funds). As a result, these types of funds may have greater ability to make investments or use investment techniques that offer a higher degree of investment return, such as leveraging, which also may subject their fund assets to substantial risk to the investment principal. These funds, while not regulated by the SEC like mutual funds, may be indirectly supervised by the sources of their assets, which tend to be commercial and investment banks and other financial institutions. Investments in these funds also may be more difficult to sell, which could cause losses to the fund. For example, hedge funds typically require investors to keep their investment in a hedge fund for some period of time, such as one month or one year. This means investors would not be able to sell their shares of a hedge fund until such time had past. The fund is prohibited from acquiring any securities of registered open-end investment companies or registered unit investment trusts in reliance on Section 12(d)(1)(G) or Section 12(d)(1)(F) of the 1940 Act.

Short Sales may be used by the fund as part of its overall portfolio management strategies or to offset (hedge) a potential decline in the value of a security. The fund may engage in short sales that are either “against the box” or “uncovered.” A short sale is “against the box” if, at all times during which the short position is open, the fund owns at least an equal amount of the securities or securities convertible into, or has the right to acquire, at no added cost, the securities of the same issue as the securities that are sold short. A short sale against the box is a taxable transaction to the fund with respect to the securities that are sold short. “Uncovered” short sales are transactions under which the fund sells a security it does not own. To complete such transaction, the fund may borrow the security through a broker to make delivery to the buyer and, in doing so, the fund becomes obligated to replace the security borrowed by purchasing the security at the market price at the time of the replacement. The fund also may have to pay a fee to borrow particular securities, which would increase the cost of the security. In addition, the fund is often obligated to pay any accrued interest and dividends on the securities until they are replaced. The proceeds of the short sale position will be retained by the broker until the fund replaces the borrowed securities.

34

Table of Contents

The fund will incur a loss if the price of the security sold short increases between the time of the short sale and the time the fund replaces the borrowed security and, conversely, the fund will realize a gain if the price declines. Any gain will be decreased, and any loss increased, by the transaction costs described above. A short sale creates the risk of an unlimited loss, as the price of the underlying securities could theoretically increase without limit, thus increasing the cost of buying those securities to cover the short position. If the fund sells securities short “against the box,” it may protect unrealized gains, but will lose the opportunity to profit on such securities if the price rises. The successful use of short selling as a hedging strategy may be adversely affected by imperfect correlation between movements in the price of the security sold short and the securities being hedged.

The fund’s obligation to replace the securities borrowed in connection with a short sale will be secured by collateral deposited with the broker that consists of cash or other liquid securities. In addition, the fund will earmark cash or liquid assets or place in a segregated account an amount of cash or other liquid assets equal to the difference, if any, between (1) the market value of the securities sold short, marked-to-market daily, and (2) any cash or other liquid securities deposited as collateral with the broker in connection with the short sale.

Temporary Defensive Strategies are strategies the fund may take for temporary or defensive purposes. The investment strategies for the fund are those that the fund uses during normal circumstances. The fund may hold up to 100% of its assets in cash, cash equivalents and other short-term investments for temporary or defensive purposes. The fund may utilize such tactics when the investment adviser believes that market or economic interests are unfavorable for investors. Under such circumstances, the fund may not achieve its investment objective.

Trust Preferred Securities . The fund may purchase trust preferred securities which are preferred stocks issued by a special purpose trust subsidiary backed by subordinated debt of the corporate parent. These securities typically bear a market rate coupon comparable to interest rates available on debt of a similarly rated company. The securities are generally senior in claim to standard preferred stock but junior to other bondholders. Holders of the trust preferred securities have limited voting rights to control the activities of the trust and no voting rights with respect to the parent company.

Trust preferred securities may have varying maturity dates, at times in excess of 30 years, or may have no specified maturity date with an onerous interest rate adjustment if not called on the first call date. Dividend payments of the trust preferred securities generally coincide with interest payments on the underlying subordinated debt. Trust preferred securities generally have a yield advantage over traditional preferred stocks, but unlike preferred stocks, distributions are treated as interest rather than dividends for federal income tax purposes.

Trust preferred securities are subject to unique risks, which include the fact that dividend payments will only be paid if interest payments on the underlying obligations are made, which interest payments are dependent on the financial condition of the parent corporation and may be deferred for up to 20 consecutive quarters. There is also the risk that the underlying obligations, and thus the trust preferred securities, may be prepaid after a stated call date or as a result of certain tax or regulatory events, resulting in a lower yield to maturity.

Trust preferred securities prices fluctuate for several reasons including changes in investors’ perception of the financial condition of an issuer or the general condition of the market for trust preferred securities, or when political or economic events affecting the issuers occur. Trust preferred securities are also (a) sensitive to interest rate fluctuations, as the cost of capital rises and borrowing costs increase in a rising interest rate environment, and (b) subject to the risk that they may be called for redemption in a falling interest rate environment.

U.S. Government Securities are issued by the U.S. Treasury or issued or guaranteed by the U.S. government or any of its agencies or instrumentalities. Not all U.S. government securities are backed by the full faith and credit of the United States. Some U.S. government securities, such as those issued by Fannie Mae, Freddie Mac, the Student Loan Marketing Association (SLMA or Sallie Mae), and the Federal Home Loan Banks (FHLB), are supported by a line of credit the issuing entity has with the U.S. Treasury. Others are supported solely by the credit of the issuing agency or instrumentality such as obligations issued by the Federal Farm Credit Banks Funding Corporation (FFCB). There can be no assurance that the U.S. government will provide financial support to U.S. government securities of its agencies and instrumentalities if it is not obligated to do so under law. Of course U.S. government securities, including U.S. Treasury securities, are among the safest securities, however, not unlike other debt securities, they are still sensitive to interest rate changes, which will cause their yields and prices to fluctuate.

On September 7, 2008, the U.S. Treasury announced a federal takeover of Fannie Mae and Freddie Mac, placing the two federal instrumentalities in conservatorship. Under 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 up to $100 billion per instrumentality as needed, including the contribution of cash capital to the instrumentalities in the event their liabilities exceed their assets. On May 6, 2009, the U.S. Treasury increased its maximum commitment to each instrumentality under the SPAs to $200 billion per instrumentality. On December 24, 2009, the U.S. Treasury further amended the SPAs to allow the cap on 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. At the start of 2013, the unlimited support the U.S. Treasury extended to the two companies expired – Fannie Mae’s bailout is capped at $125 billion and Freddie Mac has a limit of $149 billion. On August 17, 2012, the U.S. Treasury announced that it was again amending the SPAs 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. It is anticipated that the new amendment would put Fannie Mae and Freddie Mac in a better position to service their debt.

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.

On August 5, 2011, S&P lowered the long-term sovereign credit rating assigned to the United States to AA+ with a negative outlook. On August 8, 2011, S&P downgraded the long-term senior debt rating of Fannie Mae and Freddie Mac to AA+ with a negative outlook. The long-term impacts of any future downgrades are unknown. However, any future downgrades could have a material adverse impact on global financial markets and worldwide economic conditions, and could negatively impact the fund.

INVESTMENT LIMITATIONS

The following investment limitations are fundamental investment polices and restrictions and may be changed only by vote of a majority of the fund’s outstanding voting securities.

Table of Contents

The fund may not:

The following descriptions of the 1940 Act may assist investors in understanding the above policies and restrictions.

Concentration . The SEC has presently defined concentration as investing 25% or more of an investment company’s net assets in an industry or group of industries, with certain exceptions, such as with respect to investments in obligations issued or guaranteed by the U.S. government or its agencies and instrumentalities, or tax-exempt obligations of state or municipal governments and their political subdivisions.

Borrowing . The 1940 Act presently allows the fund to borrow from any bank (including pledging, mortgaging or hypothecating assets) in an amount up to 33 1/3% of its total assets (not including temporary borrowings).

Diversification. Under the 1940 Act and the rules, regulations and interpretations thereunder, a “diversified company,” as to 75% of its total assets, may not purchase securities of any issuer (other than obligations of, or guaranteed by, the U.S. government or its agencies, or instrumentalities or securities of other investment companies) if, as a result, more than 5% of its total assets would be invested in the securities of such issuer, or more than 10% of the issuer’s voting securities would be held by the fund.

Lending . Under the 1940 Act, the fund may only make loans if expressly permitted by its investment policies. The fund’s non-fundamental investment policy on lending is set forth below.

Underwriting. Under the 1940 Act, underwriting securities involves the fund purchasing securities directly from an issuer for the purpose of selling (distributing) them or participating in any such activity either directly or indirectly. Under the 1940 Act, a diversified fund may not make any commitment as underwriter, if immediately thereafter the amount of its outstanding underwriting commitments, plus the value of its investments in securities of issuers (other than investment companies) of which it owns more than 10% of the outstanding voting securities, exceeds 25% of the value of its total assets.

Real Estate. The 1940 Act does not directly restrict the fund’s ability to invest in real estate, but does require every fund to have a fundamental investment policy governing such investments. The fund has adopted a fundamental policy that would permit direct investment in real estate. However, the fund has adopted a non-fundamental investment policy that prohibits it from investing directly in real estate. This non-fundamental policy may be changed only by vote of the fund’s Board of Trustees.

Senior Securities. Senior securities may include any obligation or instrument issued by the fund evidencing indebtedness. The 1940 Act generally prohibits funds from issuing senior securities, although it provides allowances for certain borrowings and certain other investments, such as short sales, reverse repurchase agreements, firm commitment agreements and standby commitments, with appropriate earmarking or segregation of assets to cover such obligation.

Subsequent Changes In Net Assets

Policies and investment limitations that state a maximum percentage of assets that may be invested in a security or other asset, or that set forth a quality standard shall be measured immediately after and as a result of the fund’s acquisition of such security or asset, unless otherwise noted. Except with respect to limitations on borrowing and futures and option contracts, any subsequent change in net assets or other circumstances does not require the fund to sell an investment if it could not then make the same investment. With respect to the limitation on illiquid securities, in the event that a subsequent change in net assets or other circumstances causes 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.
