ADDITIONAL INFORMATION ON PORTFOLIO INSTRUMENTS, STRATEGIES AND INVESTMENT POLICIES

The Funds invest in a variety of securities and employ a number of investment techniques, which involve certain risks. The Prospectus discusses each Fund’s principal investment strategies, investment techniques and risks. Therefore, you should carefully review the Prospectus for the Funds. This SAI contains information about non-principal investment strategies the Funds may use, as well as further information about certain principal strategies that are discussed in the Prospectus.

Bank and Corporate Loans

The Funds may invest in bank and corporate loans. Commercial banks and other financial institutions or institutional investors make bank or corporate loans to companies that need capital to grow or restructure. Borrowers generally pay interest on bank or corporate loans at rates that change in response to changes in market interest rates such as the London Interbank Offered Rate (LIBOR) or the prime rates of U.S. banks. As a result, the value of bank and corporate loan investments is generally less exposed to the adverse effects of shifts in market interest rates than investments that pay a fixed rate of interest. The loan instruments in which a Fund may invest may involve borrowers, agents, co-lenders and collateral located both within and outside the United States, including in emerging market countries. Bank and corporate loans may include, but are not limited to, interests in trade finance loan transactions, pre-export/import finance transactions, factoring, syndicated loan transactions and forfeiting transactions.

Leading financial institutions often act as agent for a broader group of lenders, generally referred to as a syndicate. The syndicate’s agent arranges the bank or corporate loans, holds collateral and accepts payments of principal and interest. By investing in a corporate or bank loan, a Fund may become a member of the syndicate. A financial institution’s employment as agent might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent would generally be appointed to replace the terminated agent, and assets held by the agent under the loan agreement should remain available to holders of such indebtedness. However, if assets held by the agent for the benefit of a 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 bank or corporate loan and could suffer a loss of principal and/or interest.

The bank and corporate loans in which a Fund invests are subject to the risks that generally apply to fixed-income securities, such as interest rate risk, credit risk, liquidity risk, as well as, where applicable, foreign securities risk, emerging markets risk, and lower quality or high-yield risk. Although borrowers frequently provide collateral to secure repayment of these obligations, they do not always do so. If they do provide collateral, the value of the collateral may not completely cover the borrower’s obligations at the time of a default. Collateral may include security interests in receivables, goods, commodities, or real property. For trade finance loan transactions, the collateral itself may be the source of proceeds to repay the loan (i.e., the borrower’s ability to repay the loan will be dependent on the borrower’s ability to sell, and the purchaser’s ability to buy, the goods or commodities that are collateral for the loan). Interests in loan instruments may be tranched or tiered with respect to collateral rights. If a borrower files for protection from its creditors under the U.S. bankruptcy laws, these laws may limit a Fund’s rights to its collateral. In addition, the value of collateral may erode during a bankruptcy case. In the event of a bankruptcy, the holder of a bank or corporate loan may not recover its principal, may experience a long delay in recovering its investment and may not receive interest during the delay. Unsecured loans expose the lenders, and thus the Fund, to increased credit risk.

3

The trading market for many bank and corporate loans, including those relating to trade finance, may be limited or less developed than the secondary market for bonds and notes. Therefore, a Fund may experience difficulties in selling its bank or corporate loans. In many cases, loans and loan-related instruments may be considered to be illiquid due to the length of time required to transfer an interest in a loan or a related instrument.

Borrowing

Each Fund may borrow money from banks, limited by each Fund’s fundamental investment restriction (generally, 33  ¹ ⁄ ₃ % of its total assets (including the amount borrowed)), including borrowings for temporary or emergency purposes. In addition to borrowings that are subject to 300% asset coverage and are considered by the U.S. Securities and Exchange Commission (“SEC”) to be permitted “senior securities,” the Fund is also permitted under the 1940 Act to borrow for temporary purposes in an amount not exceeding 5% of the value of its total assets at the time when the loan is made. A loan will be presumed to be for temporary purposes if it is repaid within 60 days and is not extended or renewed. A Fund may engage in mortgage dollar roll and reverse repurchase agreements which may be considered a form of borrowing unless the Fund covers its exposure by segregating or earmarking liquid assets.

Asset Segregation . Pursuant to current guidance from the staff of the SEC, financial instruments that involve a Fund’s obligation to make future payments to third parties will not be deemed to be creating any “senior security” provided that the Fund “covers” its obligations. Financial instruments that involve an obligation to make future payments to third parties can include, among others, (i) securities purchased on a when-issued, delayed delivery, or to be announced basis; (ii) futures contracts, (iii) forward currency contracts; (iv) swaps; (v) written options; (vi) unfunded commitments; (vii) securities sold short; and (viii) reverse repurchase agreements. A Fund is deemed to have “covered” its obligations involving such a financial instrument when the Fund enters into an offsetting financial position, or segregates liquid assets (such as cash, cash equivalents or other liquid portfolio securities) equal to the Fund’s exposures relating to the financial instrument, as determined on a daily basis. Segregated assets are not required to be physically segregated from other Fund assets, but may be segregated through appropriate notation on the books of a Fund or the Fund’s custodian.

The obligation to cover a financial instrument may require a Fund to sell a portfolio security or exit a transaction, including a transaction in a financial instrument, at a disadvantageous time or price in order to segregate the required amount of assets. Should segregated assets decline in value, a Fund will be required to segregate additional assets or reduce its position in the financial instrument. In addition, segregated assets may not be available to satisfy redemptions or for other purposes, until a Fund’s obligations under the financial instruments have been satisfied.

The segregated amount for futures and forward contracts that require only cash settlement, and swap agreements that call for periodic netting between a Fund and its counterparty, is liquid assets equal to the net amount due under the contract, as determined daily on a mark-to-market basis. For futures, forwards and swaps that may physically settle, a Fund will cover its position by segregating liquid assets equal to the contract’s full notional value (less any margin posted). This may limit the Fund’s ability to use these instruments, to the extent that more assets will be required to cover a Fund’s obligations.

Leverage . The use of leverage by a Fund creates an opportunity for greater total return, but, at the same time, creates special risks. Although the principal of such borrowings will be fixed, a Fund’s assets may change in value during the time the borrowings are outstanding. Borrowings will create interest expenses for the Fund which can exceed the income from the assets purchased with the borrowings. To the extent the income or capital appreciation derived from securities purchased with borrowed funds exceeds the interest a Fund will have to pay on the borrowings, the Fund’s return will be greater than if leverage had not been used. Conversely, if the income or capital appreciation from the securities purchased with such borrowed funds is not sufficient to cover the cost of borrowing, the return to a Fund will be less than if leverage had not been used, and therefore the amount available for distribution

4

to shareholders as dividends and other distributions will be reduced. In the latter case, a Fund’s subadviser in its best judgment nevertheless may determine to maintain the Fund’s leveraged position if it expects that the benefits to the Fund’s shareholders of maintaining the leveraged position will outweigh the current reduced return.

Certain types of borrowings by a Fund may result in the Fund being subject to covenants in credit agreements relating to asset coverage, portfolio composition requirements and other matters. It is not anticipated that observance of such covenants would impede the Fund’s subadviser from managing a Fund’s portfolio in accordance with the Fund’s investment objectives and policies. However, a breach of any such covenants not cured within the specified cure period may result in acceleration of outstanding indebtedness and require the Fund to dispose of portfolio investments at a time when it may be disadvantageous to do so.

Brady Bonds

The Funds may invest in Brady Bonds. Brady Bonds are debt securities, generally denominated in U.S. dollars, issued under the framework of the Brady Plan. The Brady Plan is an initiative announced by former U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their outstanding external commercial bank indebtedness. In restructuring its external debt under the Brady Plan framework, a debtor nation negotiates with its existing bank lenders as well as multilateral institutions such as the International Bank for Reconstruction and Development (the “World Bank”) and the International Monetary Fund (the “IMF”). The Brady Plan framework, as it has developed, contemplates the exchange of external commercial bank debt for newly issued bonds known as “Brady Bonds.” Brady Bonds also may be issued in respect of new money being advanced by existing lenders in connection with the debt restructuring. The World Bank and/or the IMF support the restructuring by providing funds pursuant to loan agreements or other arrangements that enable the debtor nation to collateralize the new Brady Bonds or to repurchase outstanding bank debt at a discount. Under these arrangements with the World Bank and/or the IMF, debtor nations have been required to agree to the implementation of certain domestic monetary and fiscal reforms. Such reforms have included the liberalization of trade and foreign investment, the privatization of state-owned enterprises and the setting of targets for public spending and borrowing. These policies and programs seek to promote the debtor country’s economic growth and development. Investors should also recognize that the Brady Plan only sets forth general guiding principles for economic reform and debt reduction, emphasizing that solutions must be negotiated on a case-by-case basis between debtor nations and their creditors. A Fund’s subadviser may believe that economic reforms undertaken by countries in connection with the issuance of Brady Bonds may make the debt of countries which have issued or have announced plans to issue Brady Bonds an attractive opportunity for investment. However, there can be no assurance that the subadviser’s expectations with respect to Brady Bonds will be realized.

Agreements implemented under the Brady Plan to date are designed to achieve debt and debt-service reduction through specific options negotiated by a debtor nation with its creditors. As a result, the financial packages offered by each country differ. The types of options have included the exchange of outstanding commercial bank debt for bonds issued at 100% of face value of such debt which carry a below-market stated rate of interest (generally known as par bonds), bonds issued at a discount from the face value of such debt (generally known as discount bonds), bonds bearing an interest rate which increases over time and bonds issued in exchange for the advancement of new money by existing lenders. Regardless of the stated face amount and stated interest rate of the various types of Brady Bonds, the applicable Funds will purchase Brady Bonds in secondary markets, as described below, in which the price and yield to the investor reflect market conditions at the time of purchase. Certain sovereign bonds are entitled to “value recovery payments” in certain circumstances, which in effect constitute supplemental interest payments but generally are not collateralized. Certain Brady Bonds have been collateralized as to principal due date at maturity (typically 30 years from the date of issuance) by U.S. Treasury zero coupon bonds with a maturity equal to the final maturity of such Brady Bonds. The U.S. Treasury bonds purchased as collateral for such Brady Bonds are financed by the IMF, the World Bank and the debtor nations’ reserves. In addition, interest payments on certain types of Brady Bonds may be collateralized by cash or high-grade securities in amounts that typically represent between 12 and 18 months of interest accruals on these instruments with the balance of the interest accruals being uncollateralized. In the event of a default with respect to collateralized Brady Bonds as a result of which the payment obligations of the issuer are accelerated, the U.S. Treasury zero coupon obligations held as collateral for the payment of principal will not be distributed to investors, nor will such obligations be sold and the proceeds distributed. The collateral will be held by the collateral agent to the scheduled maturity of the defaulted Brady Bonds, which will continue to be outstanding, at which time the face amount of the collateral will equal the principal payments that would have then been due on the Brady Bonds in the normal course. However, in light of the residual risk of the

5

Brady Bonds and, among other factors, the history of default with respect to commercial bank loans by public and private entities of countries issuing Brady Bonds, investments in Brady Bonds are considered speculative. A Fund may purchase Brady Bonds with no or limited collateralization, and, for payment of interest and (except in the case of principal collateralized Brady Bonds) principal, will rely primarily on the willingness and ability of the foreign government to make payment in accordance with the terms of the Brady Bonds.

Cyber Security Risk

With the increased use of technologies such as the internet to conduct business, each Fund is susceptible to operational, information security and related risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to, gaining unauthorized access to digital systems (e.g., through “hacking” or malicious software coding) for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks also may be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites (i.e., efforts to make network services unavailable to intended users). Cyber security failures or breaches by a Fund’s adviser, and other service providers (including, but not limited to, Fund accountants, custodians, subadvisers, transfer agents and administrators), and the issuers of securities in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with a Fund’s ability to calculate its net asset value, impediments to trading, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. While the Funds and their service providers have established business continuity plans in the event of, and systems designed to reduce the risks associated with, such cyber attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Funds cannot control the cyber security plans and systems put in place by service providers to the Funds and issuers in which the Funds invest. The Funds and their shareholders could be negatively impacted as a result.

Debt Obligations

Debt obligations are subject to the risk of an issuer’s inability to meet principal and interest payments on its obligations when due (“credit risk”) and are subject to price volatility due to such factors as interest rate sensitivity, market perception of the creditworthiness of the issuer, and general market liquidity. Lower-rated securities are more likely to react to developments affecting these risks than are more highly rated securities, which react primarily to movements in the general level of interest rates. Although the fluctuation in the price of debt securities normally is less than that of common stocks, in the past there have been extended periods of cyclical increases in interest rates that have caused significant declines in the price of debt securities in general and have caused the effective maturity of securities with prepayment features to be extended, thus effectively converting short- or intermediate-term securities (which tend to be less volatile in price) into long-term securities (which tend to be more volatile in price). In addition, a corporate event such as a restructuring, merger, leveraged buyout, takeover, or similar action may cause a decline in market value of its securities or credit quality of the company’s bonds due to factors including an unfavorable market response or a resulting increase in the company’s debt. Added debt may reduce significantly the credit quality and market value of a company’s bonds, and may thereby affect the value of its equity securities as well.

Recent market data indicates that primary dealer inventories of corporate bonds appear to be at an all-time low, relative to the market size. A significant reduction in dealer market-making capacity has the potential to decrease liquidity and increase volatility in the fixed income markets.

Duration . Duration is a measure of the average life of a fixed-income security that was developed as a more precise alternative to the concepts of “term to maturity” or “average dollar weighted maturity” as measures of “volatility” or “risk” associated with changes in interest rates. Duration incorporates a security’s yield, coupon interest payments, final maturity and call features into one measure.

Most debt obligations provide interest (“coupon”) payments in addition to final (“par”) payment at maturity. Some obligations also have call provisions. Depending on the relative magnitude of these payments and the nature of the call provisions, the market values of debt obligations may respond differently to changes in interest rates.

6

Traditionally, a debt security’s “term to maturity” has been used as a measure of the sensitivity of the security’s price to changes in interest rates (which is the “interest rate risk” or “volatility” of the security). However, “term to maturity” measures only the time until a debt security provides its final payment, taking no account of the pattern of the security’s payments prior to maturity. Average dollar weighted maturity is calculated by averaging the terms of maturity of each debt security held with each maturity “weighted” according to the percentage of assets that it represents. Duration is a measure of the expected life of a debt security on a present value basis and reflects both principal and interest payments. Duration takes the length of the time intervals between the present time and the time that the interest and principal payments are scheduled or, in the case of a callable security, expected to be received, and weights them by the present values of the cash to be received at each future point in time. For any debt security with interest payments occurring prior to the payment of principal, duration ordinarily is less than maturity. In general, all other factors being the same, the lower the stated or coupon rate of interest of a debt security, the longer the duration of the security; conversely, the higher the stated or coupon rate of interest of a debt security, the shorter the duration of the security.

There are some situations where the standard duration calculation does not reflect properly the interest rate exposure of a security. For example, floating- and variable-rate securities often have final maturities of 10 or more years; however, their interest rate exposure corresponds to the frequency of the coupon reset. Another example where the interest rate exposure is not captured properly by duration is the case of mortgage pass-through securities. The stated final maturity of such securities is generally 30 years, but current prepayment rates are more critical in determining the securities’ interest rate exposure. In these and other similar situations, a Fund’s subadviser will use more sophisticated analytical techniques to project the economic life of a security and estimate its interest rate exposure. Since the computation of duration is based on predictions of future events rather than known factors, there can be no assurance that a Fund will at all times achieve its targeted portfolio duration.

The change in market value of U.S. government fixed-income securities is largely a function of changes in the prevailing level of interest rates. When interest rates are falling, a portfolio with a shorter duration generally will not generate as high a level of total return as a portfolio with a longer duration. When interest rates are stable, shorter duration portfolios generally will not generate as high a level of total return as longer duration portfolios (assuming that long-term interest rates are higher than short-term rates, which is commonly the case.) When interest rates are rising, a portfolio with a shorter duration generally will outperform longer duration portfolios. With respect to the composition of a fixed-income portfolio, the longer the duration of the portfolio, generally, the greater the anticipated potential for total return, with, however, greater attendant interest rate risk and price volatility than for a portfolio with a shorter duration.

Ratings as Investment Criteria . High-quality, medium-quality and noninvestment grade debt obligations are characterized as such based on their ratings by nationally recognized statistical rating organizations (“NRSROs”), such as Standard & Poor’s Ratings Services (“Standard & Poor’s”) or Moody’s Investors Service (“Moody’s”). “Investment Grade” securities comprise high-quality and medium-quality obligations which are defined as securities carrying ratings by any NRSRO included in their top four categories ( e.g. , BBB- or higher by Standard & Poor’s or Baa3 or higher by Moody’s or BBB- or higher by Fitch. Securities that do not carry an investment grade rating by any of the NRSROs are considered non-investment grade, or high yield “junk” bonds. In general, the ratings of NRSROs represent the opinions of these agencies as to the quality of securities that they rate. Such ratings, however, are relative and subjective, are not absolute standards of quality and do not evaluate the market value risk of the securities. Further, credit ratings do not provide assurance against default or other loss of money. These ratings are considered in the selection of a Fund’s portfolio securities, but the Fund also relies upon the independent advice of its subadviser(s) to evaluate potential investments. This is particularly important for lower-quality securities. Among the factors that will be considered is the long-term ability of the issuer to pay principal and interest and general economic trends, as well as an issuer’s capital structure, existing debt and earnings history. Appendix A to this SAI contains further information about the rating categories of NRSROs and their significance. If a security has not received a credit rating, the Funds must rely entirely on the credit assessment of the subadviser.

Subsequent to its purchase by a Fund, an issuer of securities may cease to be rated or its rating may be reduced below the minimum required for purchase by such Fund. In addition, it is possible that an NRSRO might not change its rating of a particular issuer to reflect subsequent events. None of these events generally will require sale of such securities, but a Fund’s subadviser will consider such events in its determination of whether the Fund should continue to hold the securities.

7

In addition, to the extent that the ratings change as a result of changes in an NRSRO or its rating systems, or due to a corporate reorganization, a Fund will attempt to use comparable ratings as standards for its investments in accordance with its investment objective and policies.

Derivative Instruments

Each Fund may use instruments referred to as derivative instruments (“derivatives”). A derivative is a financial instrument the value of which is derived from another security, a commodity (such as gold or oil), a currency or an index (a measure of value or rates, such as the S&P 500 Index or the prime lending rate). Derivatives allow a Fund to increase or decrease the level of risk to which the Fund is exposed more quickly and efficiently than transactions in other types of instruments. Each Fund may use derivatives as a substitute for taking a position in a security, a group of securities or a securities index as well as for hedging purposes. The Funds, as noted in their Prospectus, also may use derivatives for speculative purposes to seek to enhance returns. The use of a derivative is speculative if a Fund is seeking primarily to achieve gains, rather than offset the risk of other positions. When a Fund invests in a derivative for speculative purposes, the Fund will be exposed fully to the risks of loss of that derivative, which may sometimes be greater than the derivative’s cost. Neither Fund may use any derivative to gain exposure to an asset or class of assets that it would be prohibited by its investment restrictions from purchasing directly.

Derivatives generally have investment characteristics that are based upon either forward contracts (under which one party is obligated to buy and the other party is obligated to sell an underlying asset at a specific price on a specified date) or option contracts (under which the holder of the option has the right but not the obligation to buy or sell an underlying asset at a specified price on or before a specified date). Consequently, the change in value of a forward-based derivative generally is proportional roughly to the change in value of the underlying asset. In contrast, the buyer of an option-based derivative generally will benefit from favorable movements in the price of the underlying asset but is not exposed to the corresponding losses that result from adverse movements in the value of the underlying asset. The seller (writer) of an option-based derivative generally will receive fees or premiums but generally is exposed to losses resulting from changes in the value of the underlying asset. Depending on the change in the value of the underlying asset, the potential for loss may be limitless. Derivative transactions may include elements of leverage and, accordingly, the fluctuation of the value of the derivative transaction in relation to the underlying asset may be magnified.

The use of these derivatives is subject to applicable regulations of the SEC, the several options and futures exchanges upon which they may be traded, and the Commodity Futures Trading Commission (“CFTC”). Nationwide Fund Advisors, with respect to its management and operation of the Funds, has claimed exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”) and, therefore, is not subject to registration or regulation as a commodity pool operator under the CEA.

Special Risks of Derivative Instruments . The use of derivatives involves special considerations and risks as described below. Risks pertaining to particular instruments are described in the sections that follow.

Options . A Fund may purchase or write put and call options on securities and indices, and may purchase options on foreign currencies, and enter into closing transactions with respect to such options to terminate an existing position. The purchase of call options serves as a long hedge, and the purchase of put options serves as a short hedge. Writing put or call options can enable a Fund to enhance income by reason of the premiums paid by the purchaser of such options. Writing call options serves as a limited short hedge because declines in the value of the hedged investment would be offset to the extent of the premium received for writing the option. However, if the security appreciates to a price higher than the exercise price of the call option, it can be expected that the option will be exercised, and a Fund will be obligated to sell the security at less than its market value or will be obligated to purchase the security at a price greater than that at which the security must be sold under the option. All or a portion of any assets used as cover for over-the-counter (“OTC”) options written by a Fund would be considered illiquid to the extent described under “Restricted, Non-Publicly Traded and Illiquid Securities” below. Writing put options serves as a limited long hedge because increases in the value of the hedged investment would be offset to the extent of the premium received for writing the option. However, if the security depreciates to a price lower than the exercise price of the put option, it can be expected that the put option will be exercised, and the Fund will be obligated to purchase the security at more than its market value.

The value of an option position will reflect, among other things, the historical price volatility of the underlying investment, the current market value of the underlying investment, the time remaining until expiration of the option, the relationship of the exercise price to the market price of the underlying investment, and general market conditions. Options that expire unexercised have no value. Options used by a Fund may include European-style options, which can be exercised only at expiration. This is in contrast to American-style options which can be exercised at any time prior to the expiration date of the option.

A Fund may effectively terminate its right or obligation under an option by entering into a closing transaction. For example, a Fund may terminate its obligation under a call or put option that it had written by purchasing an identical call or put option; this is known as a closing purchase transaction. Conversely, a Fund may terminate a position in a put or call option it had purchased by writing an identical put or call option; this is known as a closing sale transaction. Closing transactions permit the Fund to realize the profit or limit the loss on an option position prior to its exercise or expiration.

A Fund may purchase or write both OTC options and options traded on foreign and U.S. exchanges. Exchange-traded options are issued by a clearing organization affiliated with the exchange on which the option is

9

listed that, in effect, guarantees completion of every exchange-traded option transaction. OTC options are contracts between the Fund and the counterparty (usually a securities dealer or a bank) with no clearing organization guarantee. Thus, when the Fund purchases or writes an OTC option, it relies on the counterparty to make or take delivery of the underlying investment upon exercise of the option. Failure by the counterparty to do so would result in the loss of any premium paid by the Fund as well as the loss of any expected benefit of the transaction.

A Fund’s ability to establish and close out positions in exchange-listed options depends on the existence of a liquid market. A Fund generally intends to purchase or write only those exchange-traded options for which there appears to be a liquid secondary market. However, there can be no assurance that such a market will exist at any particular time. Closing transactions can be made for OTC options only by negotiating directly with the counterparty, or by a transaction in the secondary market if any such market exists. Although a Fund will enter into OTC options only with counterparties that are expected to be capable of entering into closing transactions with a Fund, there is no assurance that such Fund will in fact be able to close out an OTC option at a favorable price prior to expiration. In the event of insolvency of the counterparty, a Fund might be unable to close out an OTC option position at any time prior to its expiration.

If a Fund is unable to effect a closing transaction for an option it had purchased, it would have to exercise the option to realize any profit. The inability to enter into a closing purchase transaction for a covered call option written by a Fund could cause material losses because the Fund would be unable to sell the investment used as a cover for the written option until the option expires or is exercised.

A Fund may engage in options transactions on indices in much the same manner as the options on securities discussed above, except that index options may serve as a hedge against overall fluctuations in the securities markets in general.

The writing and purchasing of options is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Imperfect correlation between the options and securities markets may detract from the effectiveness of attempted hedging.

Transactions using OTC options (other than purchased options) expose a Fund to counterparty risk. To the extent required by SEC regulations and guidance, a Fund will not enter into any such transactions unless it owns either (1) an offsetting (“covered”) position in securities, other options, or futures or (2) cash and liquid obligations with a value sufficient at all times to cover its potential obligations to the extent not covered as provided in (1) above. A Fund also will earmark or set aside cash and/or appropriate liquid assets in a segregated custodial account if required to do so by SEC and CFTC regulations. Assets used as cover or held in a segregated account cannot be sold while the position in the corresponding option or futures contract is open, unless they are replaced with similar assets. As a result, the commitment of a large portion of the Fund’s assets to earmarking or segregated accounts as a cover could impede portfolio management or the Fund’s ability to meet redemption requests or other current obligations.

An interest rate option is an agreement with a counterparty giving the buyer the right but not the obligation to buy or sell one of an interest rate hedging vehicle (such as a Treasury future or interest rate swap) at a future date at a predetermined price. The option buyer would pay a premium at the inception of the agreement. An interest rate option can be used to actively manage a Fund’s interest rate risk with respect to either an individual bond or an overlay of the entire portfolio.

Spread Transactions . A 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 a Fund the right to put, or sell, a security that it owns at a fixed dollar spread or fixed yield spread in relationship to another security that the Fund does not own, but which is used as a benchmark. The risk to a 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 a 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.

Futures Contracts . A Fund may enter into futures contracts, including interest rate, index, and currency futures and purchase and write (sell) related options. The purchase of futures or call options thereon can serve as a long hedge, and the sale of futures or the purchase of put options thereon can serve as a short hedge. Writing covered

10

call options on futures contracts can serve as a limited short hedge, and writing covered put options on futures contracts can serve as a limited long hedge, using a strategy similar to that used for writing covered options in securities. A Fund’s hedging may include purchases of futures as an offset against the effect of expected increases in securities prices or currency exchange rates and sales of futures as an offset against the effect of expected declines in securities prices or currency exchange rates. A Fund may write put options on futures contracts while at the same time purchasing call options on the same futures contracts in order to create synthetically a long futures contract position. Such options would have the same strike prices and expiration dates. A Fund will engage in this strategy only when a Fund’s subadviser believes it is more advantageous to a Fund than purchasing the futures contract.

To the extent required by regulatory authorities, a Fund will enter only into futures contracts that are traded on U.S. or foreign exchanges or boards of trade approved by the CFTC and are standardized as to maturity date and underlying financial instrument. These transactions may be entered into for “bona fide hedging” purposes as defined in CFTC regulations and other permissible purposes including increasing return, substituting a position in a security, group of securities or an index, and hedging against changes in the value of portfolio securities due to anticipated changes in interest rates, currency values and/or market conditions. There is no overall limit on the percentage of a Fund’s assets that may be at risk with respect to futures activities. Although techniques other than sales and purchases of futures contracts could be used to obtain or reduce a Fund’s exposure to market, currency, or interest rate fluctuations, such Fund may be able to obtain or hedge its exposure more effectively and perhaps at a lower cost through using futures contracts.

A futures contract provides for the future sale by one party and purchase by another party of a specified amount of a specific financial instrument (e.g., debt security), asset or currency for a specified price at a designated date, time, and place. An index futures contract is an agreement pursuant to which the parties agree to take or make delivery of an amount of cash equal to a specified multiplier times the difference between the value of the index at the close of the last trading day of the contract and the price at which the index futures contract was originally written. Transaction costs are incurred when a futures contract is bought or sold and margin deposits must be maintained. A futures contract may be satisfied by delivery or purchase, as the case may be, of the instrument, the currency, or by payment of the change in the cash value of the index. More commonly, futures contracts are closed out prior to delivery by entering into an offsetting transaction in a matching futures contract. Although the value of an index might be a function of the value of certain specified securities, no physical delivery of those securities is made. If the offsetting purchase price is less than the original sale price, a Fund realizes a gain; if it is more, a Fund realizes a loss. Conversely, if the offsetting sale price is more than the original purchase price, a Fund realizes a gain; if it is less, a Fund realizes a loss. The transaction costs must also be included in these calculations. There can be no assurance, however, that a Fund will be able to enter into an offsetting transaction with respect to a particular futures contract at a particular time. If a Fund is not able to enter into an offsetting transaction, the Fund will continue to be required to maintain the margin deposits on the futures contract.

No price is paid by a Fund upon entering into a futures contract. Instead, at the inception of a futures contract, the Fund is required to deposit with the futures broker or in a segregated account with its custodian, in the name of the futures broker through whom the transaction was effected, “initial margin” consisting of cash, U.S. government securities or other liquid obligations, in an amount generally equal to 10% or less of the contract value. Margin must also be deposited when writing a call or put option on a futures contract, in accordance with applicable exchange rules. Unlike margin in securities transactions, initial margin on futures contracts does not represent a borrowing, but rather is in the nature of a performance bond or good-faith deposit that is returned to a Fund at the termination of the transaction if all contractual obligations have been satisfied. Under certain circumstances, such as periods of high volatility, a Fund may be required by an exchange to increase the level of its initial margin payment, and initial margin requirements might be increased generally in the future by regulatory action.

Subsequent “variation margin” payments are made to and from the futures broker daily as the value of the futures position varies, a process known as “marking to market.” Variation margin does not involve borrowing, but rather represents a daily settlement of a Fund’s obligations to or from a futures broker. When a Fund purchases an option on a future, the premium paid plus transaction costs is all that is at risk. In contrast, when a Fund purchases or sells a futures contract or writes a call or put option thereon, it is subject to daily variation margin calls that could be substantial in the event of adverse price movements. If a Fund has insufficient cash to meet daily variation margin requirements, it might need to sell securities at a time when such sales are disadvantageous. Purchasers and sellers of futures positions and options on futures can enter into offsetting closing transactions by selling or purchasing, respectively, an instrument identical to the instrument held or written. Positions in futures and options on futures may

11

be closed only on an exchange or board of trade on which they were entered into (or through a linked exchange). Although the Funds generally intend to enter into futures transactions only on exchanges or boards of trade where there appears to be an active market, there can be no assurance that such a market will exist for a particular contract at a particular time.

Under certain circumstances, futures exchanges may establish daily limits on the amount that the price of a future or option on a futures contract can vary from the previous day’s settlement price; once that limit is reached, no trades may be made that day at a price beyond the limit. Daily price limits do not limit potential losses because prices could move to the daily limit for several consecutive days with little or no trading, thereby preventing liquidation of unfavorable positions.

If a Fund were unable to liquidate a futures contract or option on a futures contract position due to the absence of a liquid secondary market or the imposition of price limits, it could incur substantial losses, because it would continue to be subject to market risk with respect to the position. In addition, except in the case of purchased options, the Fund would continue to be required to make daily variation margin payments and might be required to maintain the position being hedged by the future or option or to maintain cash or securities in a segregated account. Certain characteristics of the futures market might increase the risk that movements in the prices of futures contracts or options on futures contracts might not correlate perfectly with movements in the prices of the investments being hedged. For example, all participants in the futures and options on futures contracts markets are subject to daily variation margin calls and might be compelled to liquidate futures or options on futures contracts positions whose prices are moving unfavorably to avoid being subject to further calls. These liquidations could increase price volatility of the instruments and distort the normal price relationship between the futures or options and the investments being hedged. Also, because initial margin deposit requirements in the futures markets are less onerous than margin requirements in the securities markets, there might be increased participation by speculators in the future markets. This participation also might cause temporary price distortions. In addition, activities of large traders in both the futures and securities markets involving arbitrage, “program trading” and other investment strategies might result in temporary price distortions.

A Fund that invests in a futures contract is subject to the risk of loss of the initial and variation margin in the event of bankruptcy of the futures commission merchant (“FCM”) with which the Fund has an open futures position. A Fund’s assets may not be fully protected in the event of the bankruptcy of the FCM or central counterparty because the Fund might be limited to recovering only a pro rata share of all available funds and margin segregated on behalf of the FCM’s customers. If the FCM fails to provide accurate reporting, a Fund is also subject to the risk that the FCM could use the Fund’s assets, which are held in an omnibus account with assets belonging to the FCM’s other customers, to satisfy its own obligations or the payment obligations of another customer to the central counterparty.

Indexed and Inverse Securities . A Fund may invest in securities the potential return of which is based on an index or interest rate. As an illustration, a Fund may invest in a debt security that pays interest based on the current value of an interest rate index, such as the prime rate. A Fund also may invest in a debt security that returns principal at maturity based on the level of a securities index or a basket of securities, or based on the relative changes of two indices. In addition, certain Funds may invest in securities the potential return of which is based inversely on the change in an index or interest rate (that is, a security the value of which will move in the opposite direction of changes to an index or interest rate). For example, a Fund may invest in securities that pay a higher rate of interest when a particular index decreases and pay a lower rate of interest (or do not fully return principal) when the value of the index increases. If a Fund invests in such securities, it may be subject to reduced or eliminated interest payments or loss of principal in the event of an adverse movement in the relevant interest rate, index or indices. Indexed and inverse securities involve credit risk, and certain indexed and inverse securities may involve leverage risk, liquidity risk and currency risk. When used for hedging purposes, indexed and inverse securities involve correlation risk. (Furthermore, where such a security includes a contingent liability, in the event of an adverse movement in the underlying index or interest rate, a Fund may be required to pay substantial additional margin to maintain the position.)

Credit Linked Notes . A credit linked note (“CLN”) is a type of hybrid instrument in which a special purpose entity issues a structured note (the “Note Issuer”) that is intended to replicate a corporate bond or a portfolio of corporate bonds. The purchaser of the CLN (the “Note Purchaser”) invests a par amount and receives a payment during the term of the CLN that equals a fixed or floating rate of interest equivalent to a highly rated funded asset (such as a bank certificate of deposit) plus an additional premium that relates to taking on the credit risk of an identified bond (the “Reference Bond”). Upon maturity of the CLN, the Note Purchaser will receive a payment equal

12

to: (i) the original par amount paid to the Note issuer, if there is neither a designated event of default (an “Event of Default”) with respect to the Reference Bond nor a restructuring of the issuer of the Reference Bond (a “Restructuring Event”); or (ii) the value of the Reference Bond if an Event of Default or a Restructuring Event has occurred. Depending upon the terms of the CLN, it is also possible that the Note Purchaser may be required to take physical delivery of the Reference Bond in the event of an Event of Default or a Restructuring Event.

Structured Notes . A Fund may use structured notes to pursue its objective. Structured notes generally are individually negotiated agreements and may be traded over-the-counter. They are organized and operated to restructure the investment characteristics of the underlying security or asset. This restructuring involves the deposit with or purchase by an entity, such as a corporation or trust, of specified instruments (such as commercial bank loans) and the issuance by that entity of one or more classes of securities (“structured securities”) backed by, or representing interests in, the underlying instruments. The cash flow on the underlying instruments may be apportioned among the newly issued structured securities to create securities with different investment characteristics, such as varying maturities, payment priorities and interest rate provisions, and the extent of such payments made with respect to structured securities is dependent on the extent of the cash flow on the underlying instruments.

With respect to structured notes, because structured securities typically involve no credit enhancement, their credit risk generally will be equivalent to that of the underlying instruments. Investments in structured securities are generally of a class that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured securities typically have higher yields and present greater risks than unsubordinated structured securities. Structured securities are sold typically in private placement transactions, and there is currently no active trading market for these securities. See also, “Description of Portfolio Instruments and Investment Policies — Restricted, Non-Publicly Traded and Illiquid Securities.”

Swap Agreements . A Fund may enter into interest rate, total return, securities index, commodity, or security and currency exchange rate swap agreements for any lawful purpose consistent with the Fund’s investment objective, such as for the purpose of attempting to obtain or preserve a particular desired return or spread at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return or spread. A Fund also may enter into swaps in order to protect against an increase in the price of, or the currency exchange rate applicable to, securities that the Fund anticipates purchasing at a later date. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from one or more days to several years. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments. The gross returns to be exchanged or “swapped” between the parties are calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a “basket” of securities representing a particular index. Swap agreements may be negotiated bilaterally and traded OTC between the two parties (for an uncleared swap) or, with respect to swaps that have been designated by the CFTC for mandatory clearing (cleared swaps), through an FCM and cleared through a clearinghouse that serves as a central counterparty. See “Uncleared Swaps” and “Cleared Swaps” below for additional explanation of cleared and uncleared swaps. Swap agreements may include interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor, or vice versa, in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. “Total return swaps” are contracts in which one party agrees to make payments of the total return from the underlying asset during the specified period, in return for payments equal to a fixed- or floating-rate of interest or the total return from another underlying asset.

The “notional amount” of the swap agreement is the agreed upon basis for calculating the obligations that the parties to a swap agreement have agreed to exchange. Under most swap agreements entered into by the Fund, the obligations of the parties would be exchanged on a “net basis.” Consequently, the Fund’s obligation (or rights) under a swap agreement generally will be equal only to 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 agreement (the “net amount”). The Fund’s obligation under a swap agreement will be accrued daily (offset against amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the maintenance of a segregated account consisting of cash or liquid assets.

13

Whether a Fund’s use of swap agreements will be successful in furthering its investment objective will depend, in part, on the Fund’s subadviser’s ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments or otherwise replicate a particular benchmark index. Swap agreements may be considered to be illiquid and, therefore, subject to the Funds’ limitation on investments in illiquid securities. If a swap transaction is unusually large or if the underlying market is illiquid, a Fund may not be able to establish or liquidate a position at a favorable time or price, which may result in losses.

New swaps regulation . The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the Dodd-Frank Act) and related regulatory developments have imposed comprehensive new regulatory requirements on swaps and swap market participants. The new regulatory framework includes: (1) registration and regulation of swap dealers and major swap participants; (2) central clearing and execution of standardized swaps; (3) margin requirements in swap transactions; (4) position limits and large trader reporting requirements; and (5) record keeping and centralized and public reporting requirements, on an anonymous basis, for most swaps. The CFTC is responsible for the regulation of most swaps, and has completed most of its rules implementing the Dodd-Frank Act swap regulations. The SEC has jurisdiction over a small segment of the market referred to as “security-based swaps,” which includes swaps on single securities or credits, or narrow-based indices of securities or credits, but has not yet completed its rulemaking.

Uncleared swaps . In an uncleared swap, the swap counterparty is typically a brokerage firm, bank or other financial institution. The Fund customarily enters into uncleared swaps based on the standard terms and conditions of an International Swaps and Derivatives Association (ISDA) Master Agreement. ISDA is a voluntary industry association of participants in the over-the-counter (OTC) derivatives markets that has developed standardized contracts used by such participants that have agreed to be bound by such standardized contracts.

In the event that one party to a swap transaction defaults and the transaction is terminated prior to its scheduled termination date, one of the parties may be required to make an early termination payment to the other. An early termination payment may be payable by either the defaulting or non-defaulting party, depending upon which of them is “in-the-money” with respect to the swap at the time of its termination. Early termination payments may be calculated in various ways, but are intended to approximate the amount the “in-the-money” party would have to pay to replace the swap as of the date of its termination.

A Fund will enter uncleared swap agreements only with counterparties that the Fund’s subadviser reasonably believes are capable of performing under the swap agreements. If there is a default by the other party to such a transaction, the Fund will have to rely on its contractual remedies (which may be limited by bankruptcy, insolvency or similar laws) pursuant to the agreements related to the transaction.

Cleared swaps . Certain swaps have been designated by the CFTC for mandatory central clearing. The Dodd-Frank Act and implementing rules will ultimately require the clearing and exchange-trading of many swaps. Mandatory exchange-trading and clearing will occur on a phased-in basis based on the type of market participant and CFTC approval of contracts for central clearing. To date, the CFTC has designated only certain of the most common types of credit default index swaps and interest rate swaps for mandatory clearing, but it is expected that the CFTC will designate additional categories of swaps for mandatory clearing. Central clearing is intended to reduce counterparty credit risk and increase liquidity, but central clearing does not necessarily eliminate these risks and may involve additional risks not involved with uncleared swaps.

In a cleared swap, a Fund’s ultimate counterparty is a central clearinghouse rather than a brokerage firm, bank or other financial institution. The Fund may either execute a cleared swap through a swap execution facility or, in certain situations where permitted,enter into a cleared swap through an executing broker. Such transactions will then be submitted for clearing and, if cleared, will be held at regulated FCMs that are members of the clearinghouse that serves as the central counterparty.

When a Fund enters into a cleared swap, it must deliver to the central counterparty (via the FCM) an amount referred to as “initial margin.” Initial margin requirements are determined by the central counterparty, but an FCM may require additional initial margin above the amount required by the central counterparty. During the term of the swap agreement, a “variation margin” amount also may be required to be paid by the Fund or may be received by the Fund in accordance with margin controls set for such accounts, depending upon changes in the price of the underlying reference instrument subject to the swap agreement. At the conclusion of the term of the swap agreement,

14

if the Fund has a loss equal to or greater than the margin amount, the margin amount is paid to the FCM along with any loss in excess of the margin amount. If the Fund has a loss of less than the margin amount, the excess margin is returned to the Fund. If the Fund has a gain, the full margin amount and the amount of the gain are paid to the Fund.

Rules adopted under the Dodd-Frank Act require centralized reporting of detailed information about many swaps, whether cleared or uncleared. This information is available to regulators and also, to a more limited extent and on an anonymous basis, to the public. Reporting of swaps data is intended to result in greater market transparency. This may be beneficial to funds that use swaps in their trading strategies. However, public reporting imposes additional recordkeeping burdens on these funds, and the safeguards established to protect anonymity are not yet tested and may not provide protection of trader identities as intended.

Certain Internal Revenue Service positions may limit a Fund’s ability to use swap agreements in a desired tax strategy. It is possible that developments in the swap markets and/or the laws relating to swap agreements, including potential government regulation, could adversely affect a Fund’s ability to benefit from using swap agreements, or could have adverse tax consequences.

Risks of cleared swaps . As noted above, under recent financial reforms, certain types of swaps are, and others eventually are expected to be, required to be cleared through a central counterparty, which may affect counterparty risk and other risks faced by a Fund. Central clearing is designed to reduce counterparty credit risk and increase liquidity compared to bilateral swaps because central clearing interposes the central clearinghouse as the counterparty to each participant’s swap, but it does not eliminate those risks completely. There is also a risk of loss by a Fund of the initial and variation margin deposits in the event of bankruptcy of the FCM with which the Fund has an open position in a swap contract. The assets of the Fund may not be fully protected in the event of the bankruptcy of the FCM or central counterparty because the Fund might be limited to recovering only a pro rata share of all available funds and margin segregated on behalf of an FCM’s customers. If the FCM does not provide accurate reporting, the Fund is also subject to the risk that the FCM could use the Fund’s assets, which are held in an omnibus account with assets belonging to the FCM’s other customers, to satisfy its own financial obligations or the payment obligations of another customer to the central counterparty.

With cleared swaps, a Fund may not be able to obtain as favorable terms as it would be able to negotiate for a bilateral, uncleared swap. In addition, an FCM may unilaterally amend the terms of its agreement with the Fund, which may include the imposition of position limits or additional margin requirements with respect to the Fund’s investment in certain types of swaps. Central counterparties and FCMs generally can require termination of existing cleared swap transactions at any time, and also can require increases in margin above the margin that is required at the initiation of the swap agreement. Additionally, depending on a number of factors, the margin required under the rules of the clearinghouse and FCM may be in excess of the collateral required to be posted by a Fund to support its obligations under a similar uncleared swap. However, regulators are expected to adopt rules imposing certain margin requirements, including minimums, on uncleared swaps in the near future, which could change this comparison.

Finally, a Fund is subject to the risk that, after entering into a cleared swap with an executing broker, no FCM or central counterparty is willing or able to clear the transaction. In such an event, the Fund may be required to break the trade and make an early termination payment to the executing broker.

Total Rate of Return Swaps . Total rate of return swaps are contracts in which one party agrees to make payments based on the total return from the underlying asset during the specified period, in return for payments equal to a fixed or floating rate of interest or the total return from another underlying asset. A total rate of return swap will allow the Fund to quickly and cost effectively invest cash flows into a diversified basket of assets which has the risk/return prospect of a stated benchmark.

Interest Rate Swaps . In an interest rate swap, the parties exchange their rights to receive interest payments on a security or other reference rate. For example, they might swap the right to receive floating rate payments for the right to receive for fixed rate payments. Interest rate swaps entail both interest rate risk and credit risk. There is a risk that based on movements of interest rates, the payments made under a swap agreement will be greater than the payments received, as well as the risk that the counterparty will fail to meet its obligations.

Hybrid Instruments . Hybrid instruments combine elements of derivative contracts with those of another security (typically a fixed-income security). All or a portion of the interest or principal payable on a hybrid security is

15

determined by reference to changes in the price of an underlying asset or by reference to another benchmark (such as interest rates, currency exchange rates or indices). Hybrid instruments also include convertible securities with conversion terms related to an underlying asset or benchmark.

The risks of investing in hybrid instruments reflect a combination of the risks of investing in securities, options, futures and currencies, and depend upon the terms of the instrument. Thus, an investment in a hybrid instrument may entail significant risks in addition to those associated with traditional fixed-income or convertible securities. Hybrid instruments are also potentially more volatile and carry greater interest rate risks than traditional instruments. Moreover, depending on the structure of the particular hybrid, it may expose the Fund to leverage risks or carry liquidity risks.

Credit Default Swaps . A Fund may enter into credit default swap contracts for hedging purposes or to create direct or synthetic short or long exposure to domestic or foreign corporate or sovereign debt securities.

As the seller in a credit default swap contract, a Fund would be required to pay the par (or other agreed-upon) value of a referenced debt obligation to the counterparty in the event of a default (or similar event) by a third party, such as a U.S. or foreign 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 (or similar event) occurs. If no event of default (or similar event) occurs, the Fund would keep the stream of payments and would have no payment of obligations. As the seller in a credit default swap contract, the Fund effectively would add economic leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

As the purchaser in a credit default swap contract, a Fund would function as the counterparty referenced in the preceding paragraph. This would involve the risk that the investment might expire worthless. It also would involve credit risk – that the seller may fail to satisfy its payment obligations to the Fund in the event of a default (or similar event). As the purchaser in a credit default swap contract, the Fund’s investment would generate income only in the event of an actual default (or similar event) by the issuer of the underlying obligation.

Foreign Currency-Related Derivative Strategies - Special Considerations . A Fund may use futures and options on futures on foreign currencies and forward currency contracts to hedge against movements in the values of the foreign currencies in which a Fund’s securities are denominated. Currency contracts also may be purchased such that net exposure to an individual currency exceeds the value of the Fund’s securities that are denominated in that particular currency. A Fund may engage in currency exchange transactions to protect against uncertainty in the level of future exchange rates and also may engage in currency transactions to increase income and total return. Such currency hedges can protect against price movements in a security the Fund owns or intends to acquire that are attributable to changes in the value of the currency in which it is denominated. Such hedges do not, however, protect against price movements in the securities that are attributable to other causes.

A Fund might seek to hedge against changes in the value of a particular currency when no hedging instruments on that currency are available or such hedging instruments are more expensive than certain other hedging instruments. In such cases, a Fund may hedge against price movements in that currency by entering into transactions using hedging instruments on another foreign currency or a basket of currencies, the values of which a subadviser believes will have a high degree of positive correlation to the value of the currency being hedged. The risk that movements in the price of the hedging instrument will not correlate perfectly with movements in the price of the currency being hedged is magnified when this strategy is used.

The value of derivative instruments on foreign currencies depends on the value of the underlying currency relative to the U.S. dollar. Because foreign currency transactions occurring in the interbank market might involve substantially larger amounts than those involved in the use of such hedging instruments, a Fund could be disadvantaged by having to deal in the odd lot market (generally consisting of transactions of less than $1 million) for the underlying foreign currencies at prices that are less favorable than for round lots.

There is no systematic reporting of last sale information for foreign currencies or any regulatory requirement that quotations available through dealers or other market sources be firm or revised on a timely basis. Quotation information generally is representative of very large transactions in the interbank market and thus might not reflect

16

odd-lot transactions where rates might be less favorable. The interbank market in foreign currencies is a global, round-the-clock market. To the extent the U.S. options or futures markets are closed while the markets for the underlying currencies remain open, significant price and rate movements might take place in the underlying markets that cannot be reflected in the markets for the derivative instruments until they reopen.

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

Permissible foreign currency options will include options traded primarily in the OTC market. Although options on foreign currencies are traded primarily in the OTC market, a Fund will normally purchase OTC options on foreign currency only when a Fund’s subadviser believes a liquid secondary market will exist for a particular option at any specific time.

Forward Currency Contracts . A forward currency contract 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 are entered into in the interbank market conducted directly between currency traders (usually large commercial banks) and their customers.

At or before the maturity of a forward currency contract, a Fund may either sell a portfolio security and make delivery of the currency, or retain the security and fully or partially offset its contractual obligation to deliver the currency by purchasing a second contract. If a Fund retains the portfolio security and engages in an offsetting transaction, the Fund, at the time of execution of the offsetting transaction, will incur a gain or a loss to the extent that movement has occurred in forward currency contract prices.

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

Markets for trading foreign forward currency contracts offer less protection against defaults than is available when trading in currency instruments on an exchange. Forward contracts are subject to the risk that the counterparty to such contract will default on its obligations. Since a forward foreign currency exchange contract is not guaranteed by an exchange or clearinghouse, a default on the contract would deprive a Fund of unrealized profits or the benefits of a currency hedge, impose transaction costs or force the Fund to cover its purchase or sale commitments, if any, at the current market price. In addition, the institutions that deal in forward currency contracts are not required to continue to make markets in the currencies they trade and these markets can experience periods of illiquidity. To the extent that a substantial portion of a Fund’s total assets, adjusted to reflect the Fund’s net position after giving effect to currency transactions, is denominated or quoted in currencies of foreign countries, the Fund will be more susceptible to the risk of adverse economic and political developments within those countries.

Currency Hedging . While the values of forward currency contracts, currency options, currency futures and options on futures may be expected to correlate with exchange rates, they will not reflect other factors that may affect the value of a Fund’s investments. A currency hedge, for example, should protect a Yen-denominated bond against a decline in the Yen, but will not protect a Fund against price decline if the issuer’s creditworthiness deteriorates. Because the value of a Fund’s investments denominated in foreign currencies will change in response to many factors other than exchange rates, a currency hedge may not be entirely successful in mitigating changes in the value of a Fund’s investments denominated in foreign currencies over time.

A decline in the dollar value of a foreign currency in which a Fund’s securities are denominated will reduce the dollar value of the securities, even if their value in the foreign currency remains constant. The use of currency hedges does not eliminate fluctuations in the underlying prices of the securities, but it does establish a rate of exchange that can be achieved in the future. In order to protect against such diminutions in the value of securities it

17

holds, a Fund may purchase put options on the foreign currency. If the value of the currency does decline, the Fund will have the right to sell the currency for a fixed amount in dollars and will thereby offset, in whole or in part, the adverse effect on its securities that otherwise would have resulted. Conversely, if a rise in the dollar value of a currency in which securities to be acquired are denominated is projected, thereby potentially increasing the cost of the securities, a Fund may purchase call options on the particular currency. The purchase of these options could offset, at least partially, the effects of the adverse movements in exchange rates. Although currency hedges limit the risk of loss due to a decline in the value of a hedged currency, at the same time, they also limit any potential gain that might result should the value of the currency increase.

A Fund may enter into foreign currency exchange transactions to hedge its currency exposure in specific transactions or portfolio positions. Currency contracts also may be purchased such that net exposure to an individual currency exceeds the value of the Fund’s securities that are denominated in that particular currency. Transaction hedging is the purchase or sale of forward currency with respect to specific receivables or payables of a Fund generally accruing in connection with the purchase or sale of its portfolio securities. Position hedging is the sale of forward currency with respect to portfolio security positions. A Fund may not position hedge to an extent greater than the aggregate market value (at the time of making such sale) of the hedged securities.

Non-Deliverable Forwards . The Funds may, from time to time, engage in non-deliverable forward transactions to manage currency risk or to gain exposure to a currency without purchasing securities denominated in that currency. A non-deliverable forward is a transaction that represents an agreement between a Fund and a counterparty (usually a commercial bank) to buy or sell a specified (notional) amount of a particular currency at an agreed upon foreign exchange rate on an agreed upon future date. Unlike other currency transactions, there is no physical delivery of the currency on the settlement of a non-deliverable forward transaction. Rather, the Fund and the counterparty agree to net the settlement by making a payment in U.S. dollars or another fully convertible currency that represents any differential between the foreign exchange rate agreed upon at the inception of the non-deliverable forward agreement and the actual exchange rate on the agreed upon future date. Thus, the actual gain or loss of a given non-deliverable forward transaction is calculated by multiplying the transaction’s notional amount by the difference between the agreed upon forward exchange rate and the actual exchange rate when the transaction is completed.

When a Fund enters into a non-deliverable forward transaction, the Fund’s custodian will maintain segregated assets in an amount not less than the value of the Fund’s unrealized loss under such non-deliverable forward transaction. If the additional segregated assets decline in value or the amount of the Fund’s commitment increases because of changes in currency rates, additional cash or securities will be designated as segregated assets on a daily basis so that the value of the account will equal the amount of the Fund’s unrealized loss under the non-deliverable forward agreement.

Since a Fund generally may only close out a non-deliverable forward with the particular counterparty, there is a risk that the counterparty will default on its obligation under the agreement. If the counterparty defaults, a Fund will have contractual remedies pursuant to the agreement related to the transaction, but there is no assurance that contract counterparties will be able to meet their obligations pursuant to such agreements or that, in the event of a default, a Fund will succeed in pursuing contractual remedies. The Fund thus assumes the risk that it may be delayed or prevented from obtaining payments owed to it pursuant to non-deliverable forward transactions.

In addition, where the currency exchange rates that are the subject of a given non-deliverable forward transaction do not move in the direction or to the extent anticipated, a Fund could sustain losses on the non-deliverable forward transaction. A Fund’s investment in a particular non-deliverable forward transaction will be affected favorably or unfavorably by factors that affect the subject currencies, including economic, political and legal developments that impact the applicable countries, as well as exchange control regulations of the applicable countries. These risks are heightened when a non-deliverable forward transaction involves currencies of emerging market countries because such currencies can be volatile and there is a greater risk that such currencies will be devalued against the U.S. dollar or other currencies.

The SEC and CFTC consider non-deliverable forwards as swaps, and they are therefore included in the definition of “commodity interests.” Non-deliverable forwards have historically been traded in the OTC market. However, as swaps, non-deliverable forwards may become subject to central clearing and trading on public facilities. Currency and cross currency forwards that qualify as deliverable forwards are not regulated as swaps for most

18

purposes, and thus are not deemed to be commodity interests. However, such forwards are subject to some requirements applicable to swaps, including reporting to swap data repositories, documentation requirements, and business conduct rules applicable to swap dealers. CFTC regulation of currency and cross currency forwards, especially non-deliverable forwards, may restrict a Fund’s ability to use these instruments in the manner described above or subject Nationwide Fund Advisors (“NFA”) to CFTC registration and regulation as a commodity pool operator.

Foreign Commercial Paper . The Funds may invest in commercial paper which is indexed to certain specific foreign currency exchange rates. The terms of such commercial paper provide that its principal amount is adjusted upward or downward (but not below zero) at maturity to reflect changes in the exchange rate between two currencies while the obligation is outstanding. A Fund will purchase such commercial paper with the currency in which it is denominated and, at maturity, will receive interest and principal payments thereon in that currency, but the amount or principal payable by the issuer at maturity will change in proportion to the change (if any) in the exchange rate between two specified currencies between the date the instrument is issued and the date the instrument matures. While such commercial paper entails the risk of loss of principal, the potential for realizing gains as a result of changes in the foreign currency exchange rate enables a Fund to hedge or cross-hedge against a decline in the U.S. dollar value of investments denominated in foreign currencies while providing an attractive money market rate of return. A Fund will purchase such commercial paper either for hedging purposes or in order to seek investment gain. The Funds believe that such investments do not involve the creation of a senior security, but nevertheless will earmark or establish a segregated account with respect to its investments in this type of commercial paper and maintain in such account cash not available for investment or other liquid assets having a value equal to the aggregate principal amount of outstanding commercial paper of this type.

Floating- and Variable-Rate Securities

The Funds may invest in floating- or variable-rate securities. Floating- or variable-rate obligations bear interest at rates that are not fixed, but vary with changes in specified market rates or indices, such as the prime rate, or at specified intervals. The interest rate on floating-rate securities varies with changes in the underlying index (such as the Treasury bill rate), while the interest rate on variable- or adjustable-rate securities changes at preset times based upon an underlying index. Certain of the floating- or variable-rate obligations that may be purchased by the Funds may carry a demand feature that would permit the holder to tender them back to the issuer of the instrument or to a third party at par value prior to maturity.

Some of the demand instruments purchased by a Fund may not be traded in a secondary market and derive their liquidity solely from the ability of the holder to demand repayment from the issuer or third party providing credit support. If a demand instrument is not traded in a secondary market, a Fund will nonetheless treat the instrument as “readily marketable” for the purposes of its investment restriction limiting investments in illiquid securities unless the demand feature has a notice period of more than seven days in which case the instrument will be characterized as “not readily marketable” and therefore illiquid.

Such obligations include variable-rate master demand notes, which are unsecured instruments issued pursuant to an agreement between the issuer and the holder that permit the indebtedness thereunder to vary and to provide for periodic adjustments in the interest rate. A Fund will limit its purchases of floating- and variable-rate obligations to those of the same quality as it is otherwise allowed to purchase. A Fund’s subadviser will monitor on an ongoing basis the ability of an issuer of a demand instrument to pay principal and interest on demand.

A Fund’s right to obtain payment at par on a demand instrument could be affected by events occurring between the date the Fund elects to demand payment and the date payment is due that may affect the ability of the issuer of the instrument or third party providing credit support to make payment when due, except when such demand instruments permit same day settlement. To facilitate settlement, these same day demand instruments may be held in book entry form at a bank other than a Fund’s custodian subject to a subcustodian agreement approved by the Fund between that bank and the Fund’s custodian.

Foreign Securities

Each Fund may invest in securities of issuers located outside the United States. Funds that invest in foreign securities offer the potential for more diversification than Funds that invest only in the United States because

19

securities traded on foreign markets have often (though not always) performed differently from securities traded in the United States. However, such investments often involve risks not present in U.S. investments that can increase the chances that a Fund will lose money. In particular, a Fund is subject to the risk that, because there are generally fewer investors on foreign exchanges and a smaller number of shares traded each day, it may be difficult for the Fund to buy and sell securities on those exchanges. In addition, prices of foreign securities may fluctuate more than prices of securities traded in the United States. Investments in foreign markets also may be adversely affected by governmental actions such as the imposition of punitive taxes. In addition, the governments of certain countries may prohibit or impose substantial restrictions on foreign investing in their capital markets or in certain industries. Any of these actions could severely affect security prices, impair a Fund’s ability to purchase or sell foreign securities or transfer the Fund’s assets or income back into the United States, or otherwise adversely affect a Fund’s operations. Other potential foreign market risks include changes in foreign currency exchange rates, exchange controls, difficulties in pricing securities, defaults on foreign government securities, difficulties in enforcing favorable legal judgments in foreign courts, and political and social instability. Legal remedies available to investors in certain foreign countries may be less extensive than those available to investors in the United States or other foreign countries. Dividends or interest on, or proceeds from the sale of, foreign securities may be subject to foreign withholding taxes.

Regional Risk . Adverse conditions in a certain region can adversely affect securities of issuers in other countries whose economies appear to be unrelated. To the extent that a Fund invests a significant portion of its assets in a specific geographic region, the Fund generally will have more exposure to regional economic risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a substantial portion of the Fund’s assets are invested, the Fund may experience substantial illiquidity.

Foreign Economy Risk . The economies of certain foreign markets often do not compare favorably with that of the United States with respect to such issues as growth of gross national product, reinvestment of capital, resources, and balance of payments position. Certain such economies may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, changes in international trading patterns, trade barriers, and other protectionist or retaliatory measures.

Currency Risk and Exchange Risk . Unless a Fund’s Prospectus states a policy to invest only in securities denominated in U.S. dollars, a Fund may invest in securities denominated or quoted in currencies other than the U.S. dollar. In such case, changes in foreign currency exchange rates will affect the value of a Fund’s portfolio. Generally, when the U.S. dollar rises in value against a foreign currency, a security denominated in that currency loses value because the currency is worth fewer U.S. dollars. Conversely, when the U.S. dollar decreases in value against a foreign currency, a security denominated in that currency gains value because the currency is worth more U.S. dollars. This risk, generally known as “currency risk,” means that a stronger U.S. dollar will reduce returns for U.S. investors while a weak U.S. dollar will increase those returns.

Governmental Supervision and Regulation/Accounting Standards . Many foreign governments supervise and regulate stock exchanges, brokers and the sale of securities less than does the United States. Some countries may not have laws to protect investors comparable to the U.S. securities laws. For example, some foreign countries may have no laws or rules against insider trading. Insider trading occurs when a person buys or sells a company’s securities based on nonpublic information about that company. Accounting standards in other countries are not necessarily the same as in the United States. If the accounting standards in another country do not require as much detail as U.S. accounting standards, it may be harder for Fund management to completely and accurately determine a company’s financial condition. In addition, the U.S. government has from time to time in the past imposed restrictions, through penalties and otherwise, on foreign investments by U.S. investors such as the Fund. If such restrictions should be reinstituted, it might become necessary for the Fund to invest all or substantially all of its assets in U.S. securities.

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

20

Settlement Risk . Settlement and clearance procedures in certain foreign markets differ significantly from those in the United States. Foreign settlement procedures and trade regulations also may involve certain risks (such as delays in payment for or delivery of securities) not typically generated by the settlement of U.S. investments. Communications between the United States and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates in markets that still rely on physical settlement. Settlements in certain foreign countries at times have not kept pace with the number of securities transactions; these problems may make it difficult for a Fund to carry out transactions. If a Fund cannot settle or is delayed in settling a purchase of securities, it may miss attractive investment opportunities and certain of its assets may be uninvested with no return earned thereon for some period. If a Fund cannot settle or is delayed in settling a sale of securities, it may lose money if the value of the security then declines or, if it has contracted to sell the security to another party, the Fund could be liable to that party for any losses incurred.

Investment in Emerging Markets . The Funds may invest in the securities of issuers domiciled in various countries with emerging capital markets. Emerging market countries are developing and low or middle income countries. Emerging market countries may be found in regions such as Asia, Latin America, Eastern Europe, the Middle East and Africa.

Investments in the securities of issuers domiciled in countries with emerging capital markets involve certain additional risks that do not generally apply to investments in securities of issuers in more developed capital markets, such as (i) low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets; (ii) uncertain national policies and social, political and economic instability, increasing the potential for expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments; (iii) possible fluctuations in exchange rates, differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments; (iv) national policies that may limit a Fund’s investment opportunities such as restrictions on investment in issuers or industries deemed sensitive to national interests; and (v) the lack or relatively early development of legal structures governing private and foreign investments and private property. In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.

Emerging capital markets are developing in a dynamic political and economic environment brought about by events over recent years that have reshaped political boundaries and traditional ideologies. In such a dynamic environment, there can be no assurance that any or all of these capital markets will continue to present viable investment opportunities for a Fund. In the past, governments of such nations have expropriated substantial amounts of private property, and most claims of the property owners have never been fully settled. There is no assurance that such expropriations will not reoccur. In such an event, it is possible that a Fund could lose the entire value of its investments in the affected market.

Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. In certain countries with emerging capital markets, reporting standards vary widely. As a result, traditional investment measurements used in the United States, such as price/earnings ratios, may not be applicable. Emerging market securities may be substantially less liquid and more volatile than those of mature markets, and company shares may be held by a limited number of persons. This may adversely affect the timing and pricing of the Fund’s acquisition or disposal of securities.

Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because a Fund will need to use brokers and counterparties that are less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets, and, along with other factors, could result in ownership registration being completely lost. A Fund would absorb any loss resulting from such registration problems and may have no successful claim for compensation.

21

Restrictions on Certain Investments . A number of publicly traded closed-end investment companies have been organized to facilitate indirect foreign investment in developing countries, and certain of such countries, such as Thailand, South Korea, Chile and Brazil, specifically have authorized such funds. Also, there are investment opportunities in certain of such countries in pooled vehicles that resemble open-end investment companies. In accordance with the 1940 Act, a Fund may invest up to 10% of its total assets in securities of other investment companies, not more than 5% of which may be invested in any one such company. In addition, under the 1940 Act, a Fund may not own more than 3% of the total outstanding voting stock of any investment company. These restrictions on investments in securities of investment companies may limit opportunities for a Fund to invest indirectly in certain developing countries. Shares of certain investment companies may at times be acquired only at market prices representing premiums to their net asset values (NAV). If a Fund acquires shares of other investment companies, shareholders would bear both their proportionate share of expenses of the Fund (including management and advisory fees) and, indirectly, the expenses of such other investment companies.

Depositary Receipts . A Fund may invest in foreign securities by purchasing depositary receipts, including American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”), Global Depositary Receipts (“GDRs”) and non-voting depositary receipts (“NVDRs”) or other securities convertible into securities of issuers based in foreign countries. These securities may not necessarily be denominated in the same currency as the securities into which they may be converted. Generally, ADRs, in registered form, are denominated in U.S. dollars and are designed for use in the U.S. securities markets, GDRs, in bearer form, are issued and designed for use outside the United States and EDRs (also referred to as Continental Depositary Receipts (“CDRs”)), in bearer form, may be denominated in other currencies and are designed for use in European securities markets. ADRs are receipts typically issued by a U.S. bank or trust company evidencing ownership of the underlying securities. EDRs are European receipts evidencing a similar arrangement. GDRs are receipts typically issued by non-U.S. banks and trust companies that evidence ownership of either foreign or domestic securities. For purposes of a Fund’s investment policies, ADRs, GDRs, EDRs and NVDRs are deemed to have the same classification as the underlying securities they represent. Thus, an ADR, GDR, EDR or NVDR representing ownership of common stock will be treated as common stock.

A Fund may invest in depositary receipts through “sponsored” or “unsponsored” facilities. While ADRs issued under these two types of facilities are in some respects similar, there are distinctions between them relating to the rights and obligations of ADR holders and the practices of market participants.

A depositary may establish an unsponsored facility without participation by (or even necessarily the acquiescence of) the issuer of the deposited securities, although typically the depositary requests a letter of non-objection from such issuer prior to the establishment of the facility. Holders of unsponsored ADRs generally bear all the costs of such facilities. The depositary usually charges fees upon the deposit and withdrawal of the deposited securities, the conversion of dividends into U.S. dollars, the disposition of non-cash distributions, and the performance of other services. The depositary of an unsponsored facility frequently is under no obligation to pass through voting rights to ADR holders in respect of the deposited securities. In addition, an unsponsored facility is generally not obligated to distribute communications received from the issuer of the deposited securities or to disclose material information about such issuer in the U.S. and thus there may not be a correlation between such information and the market value of the depositary receipts. Unsponsored ADRs tend to be less liquid than sponsored ADRs.

Sponsored ADR facilities are created in generally the same manner as unsponsored facilities, except that the issuer of the deposited securities enters into a deposit agreement with the depositary. The deposit agreement sets out the rights and responsibilities of the issuer, the depositary, and the ADR holders. With sponsored facilities, the issuer of the deposited securities generally will bear some of the costs relating to the facility (such as dividend payment fees of the depositary), although ADR holders continue to bear certain other costs (such as deposit and withdrawal fees). Under the terms of most sponsored arrangements, depositaries agree to distribute notices of shareholder meetings and voting instructions, and to provide shareholder communications and other information to the ADR holders at the request of the issuer of the deposited securities.

Foreign Sovereign Debt . The Funds may invest in sovereign debt obligations issued by foreign governments. To the extent that a Fund invests in obligations issued by governments of developing or emerging market countries, these investments involve additional risks. Sovereign obligors in developing and emerging market countries are among the world’s largest debtors to commercial banks, other governments, international financial organizations and other financial institutions. These obligors have in the past experienced substantial difficulties in

22

servicing their external debt obligations, which led to defaults on certain obligations and the restructuring of certain indebtedness. Restructuring arrangements have included, among other things, reducing and rescheduling interest and principal payments by negotiating new or amended credit agreements or converting outstanding principal and unpaid interest to Brady Bonds, and obtaining new credit for finance interest payments. Holders of certain foreign sovereign debt securities may be requested to participate in the restructuring of such obligations and to extend further loans to their issuers. There can be no assurance that the foreign sovereign debt securities in which a Fund may invest will not be subject to similar restructuring arrangements or to requests for new credit which adversely may affect the Fund’s holdings. Furthermore, certain participants in the secondary market for such debt may be involved directly in negotiating the terms of these arrangements and may therefore have access to information not available to other market participants.

Lending Portfolio Securities

Each Fund may lend its portfolio securities to brokers, dealers and other financial institutions, provided it receives collateral, with respect to each loan of U.S. securities, equal to at least 102% of the value of the portfolio securities loaned, and, with respect to each loan of non-U.S. securities, collateral of at least 105% of the value of the portfolio securities loaned, and at all times thereafter shall require the borrower to mark-to-market such collateral on a daily basis so that the market value of such collateral does not fall below 100% of the market value of the portfolio securities so loaned. By lending its portfolio securities, a Fund can increase its income through the investment of the collateral. For the purposes of this policy, a Fund considers collateral consisting of cash, U.S. government securities or letters of credit issued by banks whose securities meet the standards for investment by the Fund to be the equivalent of cash. From time to time, a Fund may return to the borrower or a third party which is unaffiliated with it, and which is acting as a “placing broker,” a part of the interest earned from the investment of collateral received for securities loaned.

The SEC currently requires that the following conditions be met whenever portfolio securities are loaned: (1) a Fund must receive from the borrower collateral equal to at least 100% of the value of the portfolio securities loaned; (2) the borrower must increase such collateral whenever the market value of the securities loaned rises above the level of such collateral; (3) a Fund must be able to terminate the loan at any time; (4) a Fund must receive reasonable interest on the loan, as well as any dividends, interest or other distributions payable on the loaned securities, and any increase in market value; (5) a Fund may pay only reasonable custodian fees in connection with the loan; and (6) while any voting rights on the loaned securities may pass to the borrower, a Fund must be able to terminate the loan and regain the right to vote the securities. A Fund generally will not seek to vote proxies relating to the securities on loan, unless it is in the best interests of the applicable Fund to do so. In addition, the Fund may not have on loan securities representing more than one-third of its total assets at any given time. The collateral that the Fund receives may be included in calculating the Fund’s total assets. These conditions may be subject to future modification. Loan agreements involve certain risks in the event of default or insolvency of the other party including possible delays or restrictions upon the Fund’s ability to recover the loaned securities or dispose of the collateral for the loan.

Investment of Securities Lending Collateral . The cash collateral received from a borrower as a result of a Fund’s securities lending activities will be used to purchase both fixed-income securities and securities of other issuers with debt-like characteristics that are rated A1 or P1 on a fixed-rate or floating-rate basis, including: bank obligations; commercial paper; investment agreements, funding agreements, or guaranteed investment contracts entered into with, or guaranteed by an insurance company; loan participations; master notes; medium-term notes; repurchase agreements; and U.S. government securities. Except for the investment agreements, funding agreements or guaranteed investment contracts guaranteed by an insurance company, master notes, and medium-term notes (which are described below), these types of investments are described elsewhere in the SAI. Collateral also may be invested in a money market mutual fund or short-term collective investment trust.

Investment agreements, funding agreements, or guaranteed investment contracts entered into with, or guaranteed by, an insurance company, are agreements in which an insurance company either provides for the investment of the Fund’s assets or provides for a minimum guaranteed rate of return to the investor.

Master notes are promissory notes issued usually with large, creditworthy broker-dealers on either a fixed-rate or floating-rate basis. Master notes may or may not be collateralized by underlying securities. If the master note is issued by an unrated subsidiary of a broker-dealer, then an unconditional guarantee is provided by the issuer’s parent.

23

Medium-term notes are unsecured, continuously offered corporate debt obligations. Although medium-term notes may be offered with a maturity from one to 10 years, in the context of securities lending collateral, the maturity of the medium-term note will not generally exceed two years.

Loan Participations and Assignments

The Funds may invest in Loan Participations and Assignments. Loan Participations typically will result in a Fund having a contractual relationship only with the lender, not with the borrower. A Fund will have the right to receive payments of principal, interest and any fees to which it is entitled only from the lender selling the Loan Participation and only upon receipt by the lender of the payments from the borrower. In connection with purchasing Loan Participations, a Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement relating to the loan, nor any rights of set-off against the borrower, and a Fund may not benefit directly from any collateral supporting the loan in which it has purchased the Loan Participation. As a result, a Fund will assume the credit risk of both the borrower and the lender that is selling the Loan Participation. In the event of the insolvency of the lender selling a Loan Participation, a Fund may be treated as a general creditor of the lender and may not benefit from any set-off between the lender and the borrower. When a Fund purchases Assignments from lenders, the Fund will acquire direct rights against the borrower on the loan, except that under certain circumstances such rights may be more limited than those held by the assigning lender.

A Fund may have difficulty disposing of Assignments and Loan Participations. Because the market for such instruments is not highly liquid, the Fund anticipates that such instruments could be sold only to a limited number of institutional investors. The lack of a highly liquid secondary market may have an adverse impact on the value of such instruments and will have an adverse impact on the Fund’s ability to dispose of particular Assignments or Loan Participations in response to a specific economic event, such as deterioration in the creditworthiness of the borrower.

Medium-Quality, Lower-Quality and High-Yield Securities

The Funds may invest in medium-quality securities and also in lower-quality and high-yield securities (commonly known as “junk bonds”) (hereinafter referred to as “lower-quality securities”).

Medium-Quality Securities . Medium-quality securities are obligations rated in the fourth highest rating category by any NRSRO. Medium-quality securities, although considered investment-grade, may have some speculative characteristics and may be subject to greater fluctuations in value than higher-rated securities. In addition, the issuers of medium-quality securities may be more vulnerable to adverse economic conditions or changing circumstances than issuers of higher-rated securities.

Lower-Quality/High-Yield Securities . Non-investment grade debt or lower-quality/rated securities include (i) bonds rated as low as C by Moody’s, Standard & Poor’s, or Fitch, Inc. (“Fitch”); (ii) commercial paper rated as low as C by Standard & Poor’s, Not Prime by Moody’s or Fitch 4 by Fitch; and (iii) unrated debt securities of comparable quality. Lower-quality securities, while generally offering higher yields than investment grade securities with similar maturities, involve greater risks, including the possibility of default or bankruptcy. There is more risk associated with these investments because of reduced creditworthiness and increased risk of default. Under NRSRO guidelines, lower-quality securities and comparable unrated securities will likely have some quality and protective characteristics that are outweighed by large uncertainties or major risk exposures to adverse conditions. Lower-quality securities are considered to have extremely poor prospects of ever attaining any real investment standing, to have a current identifiable vulnerability to default or to be in default, to be unlikely to have the capacity to make required interest payments and repay principal when due in the event of adverse business, financial or economic conditions, or to be in default or not current in the payment of interest or principal. They are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. The special risk considerations in connection with investments in these securities are discussed below.

Effect of Interest Rates and Economic Changes . Interest-bearing securities typically experience appreciation when interest rates decline and depreciation when interest rates rise. The market values of lower-quality and comparable unrated securities tend to reflect individual corporate developments to a greater extent than do higher-rated securities, which react primarily to fluctuations in the general level of interest rates. Lower-quality and comparable unrated securities also tend to be more sensitive to economic conditions than are higher-rated securities.

24

As a result, they generally involve more credit risks than securities in the higher-rated categories. During an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of lower-quality and comparable unrated securities may experience financial stress and may not have sufficient revenues to meet their payment obligations. The issuer’s ability to service its debt obligations also may be affected adversely by specific corporate developments, the issuer’s inability to meet specific projected business forecasts or the unavailability of additional financing. The risk of loss due to default by an issuer of these securities is significantly greater than issuers of higher-rated securities also because such securities generally are unsecured and often are subordinated to other creditors. Further, if the issuer of a lower-quality or comparable unrated security defaulted, a Fund might incur additional expenses to seek recovery. Periods of economic uncertainty and changes would also generally result in increased volatility in the market prices of these securities and thus in a Fund’s net asset value.

As previously stated, the value of a lower-quality or comparable unrated security generally will decrease in a rising interest rate market, and accordingly so will a Fund’s net asset value. If a Fund experiences unexpected net redemptions in such a market, it may be forced to liquidate a portion of its portfolio securities without regard to their investment merits. Due to the limited liquidity of lower-quality and comparable unrated securities (discussed below), a Fund may be forced to liquidate these securities at a substantial discount which would result in a lower rate of return to the Fund.

Payment Expectations . Lower-quality and comparable unrated securities typically contain redemption, call or prepayment provisions which permit the issuer of such securities containing such provisions to, at its discretion, redeem the securities. During periods of falling interest rates, issuers of these securities are likely to redeem or prepay the securities and refinance them with debt securities at a lower interest rate. To the extent an issuer is able to refinance the securities, or otherwise redeem them, a Fund may have to replace the securities with a lower-yielding security, which would result in a lower return for that Fund.

Liquidity and Valuation . A Fund may have difficulty disposing of certain lower-quality and comparable unrated securities because there may be a thin trading market for such securities. Because not all dealers maintain markets in all lower-quality and comparable unrated securities, there may be no established retail secondary market for many of these securities. The Funds anticipate that such securities could be sold only to a limited number of dealers or institutional investors. To the extent a secondary trading market does exist, it generally is not as liquid as the secondary market for higher-rated securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. As a result, a Fund’s and ability to dispose of particular securities, when necessary to meet such Fund’s liquidity needs or in response to a specific economic event, may be impacted. The lack of a liquid secondary market for certain securities also may make it more difficult for a Fund to obtain accurate market quotations for purposes of valuing that Fund’s portfolio. Market quotations generally are available on many lower-quality and comparable unrated issues only from a limited number of dealers and may not necessarily represent firm bids of such dealers or prices for actual sales. During periods of thin trading, the spread between bid and asked prices is likely to increase significantly. In addition, adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of lower-quality and comparable unrated securities, especially in a thinly traded market.

Money Market Instruments

Money market instruments in which the Funds invest may include the following types of instruments:

25

Extendable Commercial Notes . ECNs may serve as an alternative to traditional commercial paper investments. ECNs are corporate notes which are issued at a discount and structured such that, while the note has an initial redemption date (the initial redemption date is no more than 90 days from the date of issue) upon which the notes will be redeemed, the issuer on the initial redemption date may extend the repayment of the notes for up to 397 days from the date of issue without seeking note holder consent. In the event the ECN is redeemed by the issuer on its initial redemption date, investors receive a premium step-up rate, which is based on the ECN’s rating at the time. If the notes are not redeemed on the initial redemption date, they will bear interest from the initial redemption date to the maturity date of the note at a floating-rate of interest (this interest serves as a penalty yield for the issuer and a premium paid to the investor).

The ability of the issuer to exercise its option to extend the ECN beyond the initial redemption date can expose investors to interest rate risks, liquidity risks, credit risks and mark-to-market risks. Proponents of ECNs, however, argue that the punitive interest rate which applies if the ECN is extended beyond its initial redemption date will discourage issuers from extending the notes. Proponents further argue that the reputation risk associated with the decision to extend an ECN obligation will prevent issuers from extending the notes, provided that the issuer is not in extreme financial distress. The subadviser to the Funds will perform due diligence from both a credit and portfolio structure perspective before investing in ECNs.

Bank Obligations . Bank obligations include certificates of deposit, bankers’ acceptances and fixed time deposits. A certificate of deposit is a short-term negotiable certificate issued by a commercial bank against funds deposited in the bank and is either interest-bearing or purchased on a discount basis. A bankers’ acceptance is a short-term draft drawn on a commercial bank by a borrower, usually in connection with an international commercial transaction. The borrower is liable for payment as is the bank, which unconditionally guarantees to pay the draft at its face amount on the maturity date. Fixed time deposits are obligations of branches of U.S. banks or foreign banks which are payable at a stated maturity date and bear a fixed rate of interest. Although fixed time deposits do not have a market, there are no contractual restrictions on the right to transfer a beneficial interest in the deposit to a third party.

Bank obligations may be general obligations of the parent bank or may be limited to the issuing branch by the terms of the specific obligations or by government regulation. Bank obligations may be issued by domestic banks (including their branches located outside the United States), domestic and foreign branches of foreign banks and savings and loan associations.

Eurodollar and Yankee Obligations . Eurodollar bank obligations are dollar-denominated certificates of deposit and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee bank obligations are dollar-denominated obligations issued in the U.S. capital markets by foreign banks.

26

Eurodollar and Yankee bank obligations are subject to the same risks that pertain to domestic issues, notably credit risk, market risk and liquidity risk. Additionally, Eurodollar (and to a limited extent, Yankee) bank obligations are subject to certain sovereign risks and other risks associated with foreign investments. One such risk is the possibility that a sovereign country might prevent capital, in the form of dollars, from flowing across their borders. Other risks include: adverse political and economic developments; the extent and quality of government regulation of financial markets and institutions; the imposition of foreign withholding taxes; and the expropriation or nationalization of foreign issues. However, Eurodollar and Yankee bank obligations held in a Fund will undergo the same credit analysis as domestic issuers in which the Fund invests, and will have at least the same financial strength as the domestic issuers approved for the Fund.

Mortgage- and Asset-Backed Securities

Each of the Funds may invest in mortgage- and asset-backed securities. Mortgage-backed securities represent direct or indirect participation in, or are secured by and payable from, mortgage loans secured by real property. Mortgage-backed securities come in different forms. The simplest form of mortgage-backed securities is pass-through certificates. Such securities may be issued or guaranteed by U.S. government agencies or instrumentalities or may be issued by private issuers, generally originators in mortgage loans, including savings and loan associations, mortgage bankers, commercial banks, investment bankers, and special purpose entities (collectively, “private lenders”). The purchase of mortgage-backed securities from private lenders may entail greater risk than mortgage-backed securities that are issued or guaranteed by the U.S. government, its agencies or instrumentalities. Mortgage-backed securities issued by private lenders may be supported by pools of mortgage loans or other mortgage-backed securities 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 non-governmental credit enhancement. These credit enhancements may include letters of credit, reserve funds, over-collateralization, or guarantees by third parties. There is no guarantee that these credit enhancements, if any, will be sufficient to prevent losses in the event of defaults on the underlying mortgage loans. Additionally, mortgage-backed securities purchased from private lenders are not traded on an exchange and there may be a limited market for the securities, especially when there is a perceived weakness in the mortgage and real estate market sectors. Without an active trading market, mortgage-backed securities held in a Fund’s portfolio may be particularly difficult to value because of the complexities involved in assessing the value of the underlying mortgage loan.

Through its investments in mortgage-backed securities, including those issued by private lenders, a Fund may have some exposure to subprime loans, as well as to the mortgage and credit markets generally. Subprime loans refer to loans made to borrowers with weakened credit histories or with a lower capacity to make timely payments on their loans. For these reasons, the loans underlying these securities have had, in many cases, higher default rates than those loans that meet government underwriting requirements. The risk of non-payment is greater for mortgage-backed securities issued by private lenders that contain subprime loans, but a level of risk exists for all loans.

Since privately-issued mortgage certificates are not guaranteed by an entity having the credit status of GNMA or FHLMC (each of which is defined below under “U.S. Government Securities and U.S. Government Agency Securities”), such securities generally are structured with one or more types of credit enhancement. Such credit enhancement falls into two categories: (i) liquidity protection; and (ii) protection against losses resulting from ultimate default by an obligor on the underlying assets. Liquidity protection refers to the provisions of advances, generally by the entity administering the pool of assets, to ensure that the pass-through of payments due on the underlying pool occurs in a timely fashion. Protection against losses resulting from ultimate default enhances the likelihood of ultimate payment of the obligations on at least a portion of the assets in the pool. Such protection may be provided through guarantees, insurance policies or letters of credit obtained by the issuer or sponsor from third parties, through various means of structuring the transaction or through a combination of such approaches.

The ratings of mortgage-backed securities for which third-party credit enhancement provides liquidity protection or protection against losses from default are generally dependent upon the continued creditworthiness of the provider of the credit enhancement. The ratings of such securities could be subject to reduction in the event of deterioration in the creditworthiness of the credit enhancement provider even in cases where the delinquency loss experienced on the underlying pool of assets is better than expected. There can be no assurance that the private issuers or credit enhancers of mortgage-backed securities will meet their obligations under the relevant policies or other forms of credit enhancement.

Examples of credit support arising out of the structure of the transaction include “senior-subordinated securities” (multiple class securities with one or more classes subordinate to other classes as to the payment of principal thereof and interest thereon, with the result that defaults on the underlying assets are borne first by the holders of the subordinated class), creation of “reserve funds” (where cash or investments sometimes funded from a portion of the payments on the underlying assets are held in reserve against future losses) and “over-collateralization” (where the scheduled payments on, or the principal amount of, the underlying assets exceed those required to make payment of the securities and pay any servicing or other fees). The degree of credit support provided for each issue generally is based on historical information with respect to the level of credit risk associated with the underlying assets. Delinquency or loss in excess of that which is anticipated could affect adversely the return on an investment in such security.

Private lenders or government-related entities also may create mortgage loan pools offering pass-through investments where the mortgages underlying these securities may be alternative mortgage instruments, that is, mortgage instruments whose principal or interest payments may vary or whose terms to maturity may be shorter than was previously customary. As new types of mortgage-related securities are developed and offered to investors, a Fund, consistent with its investment objective and policies, may consider making investments in such new types of securities.

The yield characteristics of mortgage-backed securities differ from those of traditional debt obligations. Among the principal differences are that interest and principal payments are made more frequently on mortgage-backed securities, usually monthly, and that principal may be prepaid at any time because the underlying mortgage loans or other assets generally may be prepaid at any time. As a result, if a 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 a 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. Accelerated prepayments on securities purchased by the Fund at a premium also impose a risk of loss of principal because the premium may not have been fully amortized at the time the principal is prepaid in full.

Unlike fixed-rate mortgage-backed securities, adjustable-rate mortgage-backed securities are collateralized by or represent interest in mortgage loans with variable rates of interest. These variable-rates of interest reset periodically to align themselves with market rates. A Fund will not benefit from increases in interest rates to the extent that interest rates rise to the point where they cause the current coupon of the underlying adjustable-rate mortgages to exceed any maximum allowable annual or lifetime reset limits (or “cap rates”) for a particular mortgage. In this event, the value of the adjustable-rate mortgage-backed securities in a Fund likely would decrease. Also, a Fund’s net asset value could vary to the extent that current yields on adjustable-rate mortgage-backed securities are different than market yields during interim periods between coupon reset dates or if the timing of changes to the index upon which the rate for the underlying mortgage is based lags behind changes in market rates. During periods of declining interest rates, income to a Fund derived from adjustable-rate mortgage-backed securities which remain in a mortgage pool will decrease in contrast to the income on fixed-rate mortgage-backed securities, which will remain constant. Adjustable-rate mortgages also have less potential for appreciation in value as interest rates decline than do fixed rate investments.

There are a number of important differences among the agencies and instrumentalities of the U.S. government that issue mortgage-backed securities and among the securities that they issue. Mortgage-backed securities issued by GNMA include GNMA Mortgage Pass-Through Certificates (also known as “Ginnie Maes”), which are guaranteed as to the timely payment of principal and interest by GNMA, and such guarantee is backed by the full faith and credit of the United States. GNMA certificates also are supported by the authority of GNMA to borrow funds from the U.S. Treasury to make payments under its guarantee. Mortgage-backed securities issued by FNMA include FNMA Guaranteed Mortgage Pass-Through Certificates (also known as “Fannie Maes”), which are solely the obligations of FNMA, and are not backed by or entitled to the full faith and credit of the United States. Fannie Maes are guaranteed as to timely payment of the principal and interest by FNMA. Mortgage-backed securities issued by FHLMC (which is defined below under “U.S. Government Securities and U.S. Government Agency Securities”) include FHLMC Mortgage Participation Certificates (also known as “Freddie Macs” or “PCs”). FHLMC is a corporate instrumentality of the United States, created pursuant to an Act of Congress, which is owned entirely by

28

Federal Home Loan Banks. Securities issued by FHLMC do not constitute a debt or obligation of the United States or by any Federal Home Loan Bank. Freddie Macs entitle the holder to timely payment of interest, which is guaranteed by the FHLMC. FHLMC guarantees either ultimate collection or timely payment of all principal payments on the underlying mortgage loans. When the FHLMC does not guarantee timely payment of principal, FHLMC may remit the amount due on account of its guarantee of ultimate payment of principal at any time after default on an underlying mortgage, but in no event later than one year after it becomes payable.

Collateralized Mortgage Obligations (“CMOs”) and Multiclass Pass-Through Securities . CMOs are a more complex form of mortgage-backed security in that they are multi-class debt obligations which are collateralized by mortgage loans or pass-through certificates. As a result of changes prompted by the 1986 Tax Reform Act, most CMOs are today issued as Real Estate Mortgage Investment Conduits (“REMICs”). From the perspective of the investor, REMICs and CMOs are virtually indistinguishable. However, REMICs differ from CMOs in that REMICs provide certain tax advantages for the issuer of the obligation. Multiclass pass-through securities are interests in a trust composed of whole loans or private pass-throughs (collectively hereinafter referred to as “Mortgage Assets”). Unless the context indicates otherwise, all references herein to CMOs include REMICs and multiclass pass-through securities.

Often, CMOs are collateralized by GNMA, Fannie Mae or Freddie Mac Certificates, but also may be collateralized by Mortgage Assets. Unless the context indicates otherwise, all references herein to CMOs include REMICs and multiclass pass-through securities. Payments of principal and interest on the Mortgage Assets, and any reinvestment income thereon, provide the funds to pay debt service on the CMOs or make scheduled distributions on the multiclass pass-through securities. CMOs 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 subsidiaries of the foregoing.

In order to form a CMO, the issuer assembles a package of traditional mortgage-backed pass-through securities, or actual mortgage loans, and uses them as collateral for a multi-class security. Each class of CMOs, often referred to as a “tranche,” is issued at a specified fixed or floating coupon rate and has a stated maturity or final distribution date. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semiannual basis. The principal of and interest on the Mortgage Assets may be allocated among the several classes of a series of a CMO in innumerable ways. In one structure, payments of principal, including any principal prepayments, on the Mortgage Assets are applied to the classes of a CMO in the order of their respective stated maturities or final distribution dates, so that no payment of principal will be made on any class of CMOs until all other classes having an earlier stated maturity or final distribution date have been paid in full. As market conditions change, and particularly during periods of rapid or unanticipated changes in market interest rates, the attractiveness of the CMO classes and the ability of the structure to provide the anticipated investment characteristics may be reduced significantly. Such changes can result in volatility in the market value, and in some instances reduced liquidity, of the CMO class.

A Fund also may invest in, among others types of CMOs, parallel pay CMOs and Planned Amortization Class CMOs (“PAC Bonds”). Parallel pay CMOs are structured to provide payments of principal on each payment date to more than one class. These simultaneous payments are taken into account in calculating the stated maturity date or final distribution date of each class, which, as with other CMO structures, must be retired by its stated maturity date or a final distribution date but may be retired earlier. PAC Bonds are a type of CMO tranche or series designed to provide relatively predictable payments of principal provided that, among other things, the actual prepayment experience on the underlying mortgage loans falls within a predefined range. If the actual prepayment experience on the underlying mortgage loans is at a rate faster or slower than the predefined range or if deviations from other assumptions occur, principal payments on the PAC Bond may be earlier or later than predicted. The magnitude of the predefined range varies from one PAC Bond to another; a narrower range increases the risk that prepayments on the PAC Bond will be greater or smaller than predicted. Because of these features, PAC Bonds are generally less subject to the risks of prepayment than are other types of mortgage-backed securities.

Stripped Mortgage Securities . Stripped mortgage securities are derivative multiclass mortgage securities. Stripped mortgage securities 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 subsidiaries of the foregoing. Stripped mortgage securities have greater

29

volatility than other types of mortgage securities. Although stripped mortgage securities are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers, the market for such securities has not yet been fully developed. Accordingly, stripped mortgage securities are generally illiquid.

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

In addition to the stripped mortgage securities described above, certain Funds may invest in similar securities such as Super POs and Levered IOs which are more volatile than POs, IOs and IOettes. Risks associated with instruments such as Super POs are similar in nature to those risks related to investments in POs. IOettes represent the right to receive interest payments on an underlying pool of mortgages with similar risks as those associated with IOs. Unlike IOs, the owner also has the right to receive a very small portion of the principal. Risks connected with Levered IOs and IOettes are similar in nature to those associated with IOs. Such Funds also may invest in other similar instruments developed in the future that are deemed consistent with its investment objective, policies and restrictions. See “ADDITIONAL GENERAL TAX INFORMATION FOR THE FUNDS” in this SAI.

A Fund also may purchase stripped mortgage-backed securities for hedging purposes to protect that Fund against interest rate fluctuations. For example, since an IO will tend to increase in value as interest rates rise, it may be utilized to hedge against a decrease in value of other fixed-income securities in a rising interest rate environment. Stripped mortgage-backed securities may exhibit greater price volatility than ordinary debt securities because of the manner in which their principal and interest are returned to investors. The market value of the class consisting entirely of principal payments can be extremely volatile in response to changes in interest rates. The yields on stripped mortgage-backed securities that receive all or most of the interest generally are higher than prevailing market yields on other mortgage-backed obligations because their cash flow patterns are also volatile and there is a greater risk that the initial investment will not be fully recouped. The market for CMOs and other stripped mortgage-backed securities may be less liquid if these securities lose their value as a result of changes in interest rates; in that case, a Fund may have difficulty in selling such securities.

Asset-Backed Securities . Asset-backed securities have structural characteristics similar to mortgage-backed securities. However, the underlying assets are not first-lien mortgage loans or interests therein; rather the underlying assets are often consumer or commercial debt contracts such as motor vehicle installment sales contracts, other installment loan contracts, home equity loans, leases of various types of property and receivables from credit card and other revolving credit arrangements. However, almost any type of fixed-income assets may be used to create an asset-backed security, including other fixed-income securities or derivative instruments such as swaps. Payments or distributions of principal and interest on asset-backed securities may be supported by non-governmental credit enhancements similar to those utilized in connection with mortgage-backed securities. Asset-backed securities, though, present certain risks that are not presented by mortgage-backed securities. The credit quality of most asset-backed securities 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. Asset-backed securities may not have the benefit of any security interest in the related asset. To the extent a security interest exists, it may be more difficult for the issuer to enforce the security interest as compared to mortgage-backed securities.

Municipal Securities

The Funds may invest in municipal securities. Municipal securities include debt obligations issued by governmental entities to obtain funds for various public purposes, such as the construction of a wide range of public

30

facilities, the refunding of outstanding obligations, the payment of general operating expenses, and the extension of loans to other public institutions and facilities. Private activity bonds that are issued by or on behalf of public authorities to finance various privately-operated facilities are deemed to be municipal securities, only if the interest paid thereon is exempt from federal taxes. The Nationwide Money Market Fund may invest in municipal securities whether or not the interest paid is tax exempt as long as the securities are acceptable investments for money market funds.

Other types of municipal securities include short-term General Obligation Notes, Tax Anticipation Notes, Bond Anticipation Notes, Revenue Anticipation Notes, Project Notes, Tax-Exempt Commercial Paper, Construction Loan Notes and other forms of short-term tax-exempt loans. Such instruments are issued with a short-term maturity in anticipation of the receipt of tax funds, the proceeds of bond placements or other revenues.

Project Notes are issued by a state or local housing agency and are sold by the Department of Housing and Urban Development. While the issuing agency has the primary obligation with respect to its Project Notes, they are also secured by the full faith and credit of the United States through agreements with the issuing authority which provide that, if required, the federal government will lend the issuer an amount equal to the principal of and interest on the Project Notes.

The two principal classifications of municipal securities consist of “general obligation” and “revenue” issues. The Funds also may acquire “moral obligation” issues, which are normally issued by special purpose authorities. There are, of course, variations in the quality of municipal securities, both within a particular classification and between classifications, and the yields on municipal securities depend upon a variety of factors, including the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. Ratings represent the opinions of an NRSRO as to the quality of municipal securities. It should be emphasized, however, that ratings are general and are not absolute standards of quality, and municipal securities with the same maturity, interest rate and rating may have different yields, while municipal securities of the same maturity and interest rate with different ratings may have the same yield. Subsequent to purchase, an issue of municipal securities may cease to be rated or its rating may be reduced below the minimum rating required for purchase. The subadviser will consider such an event in determining whether a Fund should continue to hold the obligation.

An issuer’s obligations under its municipal securities are subject to the provisions of bankruptcy, insolvency, and other laws affecting the rights and remedies of creditors, such as the federal bankruptcy code, and laws, if any, which may be enacted by Congress or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon the enforcement of such obligations or upon the ability of municipalities to levy taxes. The power or ability of an issuer to meet its obligations for the payment of interest on and principal of its municipal securities may be materially adversely affected by litigation or other conditions.
