Principal Risks

The Fund is subject to the same risks that apply to all mutual funds that invest in equity securities. For instance, the value of the Fund’s investments — and therefore, the value of Fund shares — may fluctuate. Further, the Fund’s portfolio managers may select securities that underperform the stock market, the Fund’s benchmark or other mutual funds with similar investment objectives and strategies.

In addition, the Fund is subject to COUNTRY RISK, DERIVATIVES RISK, EMERGING MARKETS RISK, FOREIGN SECURITIES RISK, PREFERRED STOCK RISK, SMALLER COMPANY RISK and STOCK MARKET RISK, each of which is described in the section “Risks of Investing in the Funds” beginning on page 12.

The Fund cannot guarantee that it will achieve its investment objective. If the value of the Fund’s investments goes down, you may lose money.

As with all mutual funds, investing in Nationwide Funds involves certain risks. There is no guarantee that a Fund will meet its investment objective or that a Fund will perform as it has in the past. You may lose money if you invest in one or more Nationwide Funds.

The following information relates to the principal risks of investing in the Funds, as identified in the “Fund Summary” and “How the Funds Invest” sections for each Fund. A Fund may invest in or use other types of investments or strategies not shown below that do not represent principal strategies or raise principal risks. More information about these non-principal investments, strategies and risks is available in the Funds’ Statement of Additional Information (“SAI”).

Asset-backed securities risk – like traditional fixed-income securities, the value of asset-backed securities typically increases when interest rates fall and decreases when interest rates rise. Certain asset-backed securities may also be subject to the risk of prepayment. In a period of declining interest rates, borrowers may pay what they owe on the underlying assets more quickly than anticipated. Prepayment reduces the yield to maturity and the average life of the asset-backed securities. In addition, when a Fund reinvests the proceeds of a prepayment, it may receive a lower interest rate. In a period of rising interest rates, prepayments may occur at a slower rate than expected. As a result, the average maturity of a Fund’s portfolio may increase. The value of longer-term securities generally changes more in response to changes in interest rates than shorter-term 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. Unlike mortgage-backed securities, asset-backed securities may not have the benefit of or be able to enforce any security interest in the related asset.

Country risk – if a Fund emphasizes one or more countries, it may be more susceptible to the financial, market, political or economic events affecting the particular issuers and industries participating in such countries than funds that do not emphasize particular countries.

Credit risk – the risk that the issuer of a debt security will not make required interest payments and/or principal repayments when they are due. If an issuer defaults, the Fund may lose money. The degree of credit risk depends on both the financial condition of the issuer and the terms of the obligation. Changes in an issuer’s credit rating or the market’s perception of an issuer’s credit risk can adversely affect the prices of the securities a Fund owns. A corporate event such as a restructuring, merger, leveraged buyout, takeover, or similar action may cause a decline in market value of an issuer’s securities or credit quality of its 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. High-yield bonds, which are rated below investment grade, are generally more exposed to credit risk than investment-grade securities.

Credit ratings – “investment-grade” securities are those rated in one of the top four rating categories by nationally recognized statistical rating organizations, such as Moody’s or Standard & Poor’s, or unrated securities judged by the Fund’s subadviser to be of comparable quality. Obligations rated in the fourth-highest rating category by any rating agency are considered medium-grade securities. Medium-grade securities, although considered investment-grade, have speculative characteristics and may be subject to greater fluctuations in value than higher-rated securities. In addition, the issuers of medium-grade securities may be more vulnerable to adverse economic conditions or changing circumstances than issuers of higher-rated securities. High-yield bonds (i.e., “junk bonds”) are those that are rated below the fourth highest rating category, and therefore are not considered to be investment-grade. Ratings of securities purchased by a Fund generally are determined at the time of their purchase. Any subsequent rating downgrade of a debt obligation will be monitored generally by the subadviser to consider what action, if any, it should take consistent with its investment objective. There is no requirement that any such securities must be sold if downgraded.

Credit ratings evaluate the expectation that scheduled interest and principal payments will be made in a timely manner. They do not reflect any judgment of market risk. Credit ratings do not provide assurance against default or loss of money. For example, rating agencies might not always change their credit rating of an issuer in a timely manner to reflect events that could affect the issuer’s ability to make scheduled payments on its obligations. If a security has not received a rating, the Fund must rely entirely on the credit assessment of the Fund’s subadviser.

U.S. government and U.S. government agency securities – neither the U.S. government nor its agencies guarantee the market value of their securities, and interest rate changes, prepayments and other factors may affect the value of government securities. Some of the securities purchased by a Fund are issued by the U.S. government, such as Treasury notes, bills and bonds, and Government National Mortgage Association (“GNMA”) pass-through certificates, and are backed by the “full faith and credit” of the U.S. government (the U.S. government has the power to tax its citizens to pay these debts) and may be subject to less credit risk. Securities issued by U.S. government agencies, authorities or instrumentalities, such as the Federal Home Loan Banks, Federal National Mortgage Association (“FNMA”) and Federal Home Loan Mortgage Corporation (“FHLMC”), are neither issued nor guaranteed by the U.S. government. Although FNMA, FHLMC and the Federal Home Loan Banks are chartered by Acts of Congress, their securities are backed only by the credit of the respective instrumentality. Investors should remember that although certain government securities are

guaranteed, market price and yield of the securities or net asset value and performance of the Funds are not guaranteed.

Derivatives risk – A forward foreign currency exchange contract is an agreement to buy or sell a specific amount of currency at a future date and at a price set at the time of the contract. A currency futures contract is similar to a forward foreign currency exchange contract except that the futures contract is in a standardized form that trades on an exchange instead of being privately negotiated with a particular counterparty. Forward foreign currency exchange contracts and currency futures contracts (collectively, “currency contracts”) may reduce the risk of loss from a change in value of a currency, but they also limit any potential gains and do not protect against fluctuations in the value of the underlying stock or bond. For example, during periods when the U.S. dollar weakens in relation to a foreign currency, the Fund’s use of a currency hedging program will result in lower returns than if no currency hedging program were in effect. Currency contracts are considered to be derivatives, because their value and performance depend, at least in part, on the value and performance of an underlying currency. The Fund’s investments in currency contracts may involve a small investment relative to the amount of risk assumed. To the extent the Fund enters into these transactions, its success will depend on the subadviser’s ability to predict market movements, and their use may have the opposite effect of that intended. Risks include potential loss due to the imposition of controls by a government on the exchange of foreign currencies, the loss of any premium paid to enter into the transaction, delivery failure, default by the other party, or inability to close out a position because the trading market becomes illiquid. These risks may be heightened during volatile market conditions. To the extent that the Fund is unable to close out a position because of market illiquidity, the Fund may not be able to prevent further losses of value in its derivative holdings. The Fund’s liquidity may also be impaired to the extent that it has a substantial portion of its otherwise liquid assets marked as segregated to cover its obligations under such derivative instruments. Finally, the Fund’s use of derivatives may cause the Fund to realize higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if the Fund had not used such instruments.

Leverage – leverage may be created when an investment exposes the Fund to a risk of loss that exceeds the amount invested. Certain derivatives provide the potential for investment gain or loss that may be several times greater than the change in the value of an underlying security, asset, interest rate, index or currency, resulting in the potential for a loss that may be substantially greater than the amount invested. Some derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Because leverage can magnify the effects of changes in the value of the Fund and make the Fund’s share price more volatile, a shareholder’s investment in the Fund may be more volatile, resulting in larger gains or losses in response to the fluctuating prices of the Fund’s investments. Further, the use of leverage may require the Fund to maintain assets as “cover,” maintain segregated asset accounts, or make margin payments, which might impair the Fund’s ability to sell a portfolio security or make an investment at a time when it would otherwise be favorable to do so, or require that the Fund sell a portfolio security at a disadvantageous time.

Nationwide Fund Advisors, with respect to its management and operation of the Funds, has claimed an 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.

Emerging markets risk – the risks of foreign investments are usually much greater for emerging markets. Investments in emerging markets may be considered speculative. Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. They are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging markets have far lower trading volumes and less liquidity than developed markets. Since these markets are often small, they may be more likely to suffer sharp and frequent price changes or long-term price depression because of adverse publicity, investor perceptions or the actions of a few large investors. In addition, traditional measures of investment value used in the United States, such as price-to- earnings ratios, may not apply to certain small markets. 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.

Many emerging markets have histories of political instability and abrupt changes in policies. As a result, their governments are more likely to take actions that are hostile or detrimental to private enterprise or foreign investment than those of more developed countries, including expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments. 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 the Fund could lose the entire value of its investments in the affected market. Some countries have pervasiveness of corruption and crime that may hinder investments. Certain emerging markets may also face other significant internal or external risks, including the risk of war, and ethnic, religious and racial conflicts. In addition, governments in many emerging market countries participate to a significant degree in their economies and securities markets, which may impair investment and economic growth. National policies that may limit a Fund’s investment opportunities include restrictions on investment in issuers or industries deemed sensitive to national interests.

Emerging markets may also have 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. Sometimes, they may lack or be in the 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.

Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because the 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 that ownership exists in some emerging markets, along with other factors, could result in ownership registration being completely lost. The Fund would absorb any loss resulting from such registration problems and may have no successful claim for compensation. In addition, communications between the United States and emerging market countries may be unreliable, increasing the risk of delayed settlements or losses of security certificates.

Extension risk – the risk that principal repayments will not occur as quickly as anticipated, causing the expected maturity of a security to increase. Rapidly rising interest rates may cause prepayments to occur more slowly than expected, thereby lengthening the duration of the securities held by a Fund and making their prices more sensitive to rate changes and more volatile if the market perceives the securities’ interest rates to be too low for a longer-term investment.

Foreign securities risk – foreign securities may be more volatile, harder to price and less liquid than U.S. securities. Foreign investments involve some of the following risks as well:

Additional risks include the possibility that a foreign jurisdiction might impose or increase withholding taxes on income payable with respect to foreign securities; the possible seizure, nationalization or expropriation of the issuer or foreign deposits (in which the Fund could lose its entire investment in a certain market); and the possible adoption of foreign governmental restrictions such as exchange controls.

Regional – 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 the Fund invests a significant portion of its assets in a specific geographic region, the Fund will generally 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 currencies – foreign securities may be denominated or quoted in currencies other than the U.S. dollar. Changes in foreign currency exchange rates 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.

Foreign custody – a Fund that invests in foreign securities may hold such 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, and there may be limited or no regulatory oversight of their operations. The laws of certain countries may put limits on a Fund’s ability to recover its assets if a foreign bank, 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 a Fund holding assets outside the United States.

Depositary receipts – investments in foreign securities may be in the form of depositary receipts, such as American Depositary Receipts (“ADRs”), European Depositary Receipts (“EDRs”) and Global Depositary Receipts (“GDRs”), which typically are issued by local financial institutions and evidence ownership of the underlying securities. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Depositary receipts may or may not be jointly sponsored by the underlying issuer. The issuers of unsponsored depositary receipts are not obligated to disclose information that is, in the United States, considered material. Therefore, there may be less information available regarding these issuers and there may not be a correlation between such information and the market value of the depositary receipts. Certain depositary receipts are not listed on an exchange and therefore may be considered to be illiquid securities.

High-yield bonds risk – investment in high-yield bonds (often referred to as “junk bonds”) and other lower-rated securities involves substantial risk of loss. These securities are considered to be speculative with respect to the issuer’s ability to pay interest and principal when due and are susceptible to default or decline in market value due to adverse economic and business developments. The market values of high-yield securities tend to be very volatile, and these securities are less liquid than investment-grade debt securities. Therefore, Funds that invest in high-yield bonds are subject to the following risks:

Interest rate risk – prices of fixed-income securities generally increase when interest rates decline and decrease when interest rates increase. Prices of longer-term securities generally change more in response to interest rate changes than prices of shorter-term securities. To the extent a Fund invests a substantial portion of its assets in fixed-income securities with longer-term maturities, rising interest rates may cause the value of the Fund’s investments to decline significantly.

Duration – the duration of a fixed-income security estimates how much its price is affected by interest rate changes. For example, a duration of five years means the price of a fixed- income security will change approximately 5% for every 1% change in its yield. Thus, the higher a security’s duration, the more volatile the security.

Inflation – prices of existing fixed-rate debt securities could decline due to inflation or the threat of inflation. Inflationary expectations are generally associated with higher prevailing interest rates, which normally lower the prices of existing fixed-rate debt securities. Because inflation reduces the purchasing power of income produced by existing fixed-rate securities, the prices at which these securities trade also will be reduced to compensate for the fact that the income they produce is worth less.

Floating- and variable-rate securities – floating-rate securities have interest rates that vary with changes to a specific measure, such as the Treasury bill rate. Variable-rate securities have interest rates that change at preset times based on the specific measure. Some floating- and variable-rate securities may be callable by the issuer, meaning that they can be paid off before their maturity date and the proceeds may be required to be invested in lower-yielding securities that reduce a Fund’s income. Like other fixed-income securities, floating- and variable-rate securities are subject to interest rate risk. A Fund will only purchase a floating- or variable-rate security of the same quality as the debt securities it would otherwise purchase.

Liquidity risk – the risk that a Fund may invest to a greater degree in instruments that trade in lower volumes and may make investments that may be less liquid than other investments. It is also the risk that a Fund may make investments that may become less liquid in response to market developments or adverse investor perceptions. When there is no willing buyer and investments cannot be readily sold at the desired time or price, the Fund may have to accept a lower price or may not be able to sell the instruments at all. An inability to sell a portfolio position can adversely affect a Fund’s value or prevent a Fund from being able to take advantage of other investment opportunities. Liquidity risk may also refer to the risk that a Fund will be unable to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. To meet redemption requests, a Fund may be forced to sell liquid securities at an unfavorable time and conditions. Funds that invest in non-investment grade fixed-income securities, small- and mid-capitalization stocks, REITs and emerging country issuers will be especially subject to the risk that during certain periods, the

liquidity of particular issuers or industries, or all securities within particular investment categories, will shrink or disappear suddenly and without warning as a result of adverse economic, market or political events, or adverse investor perceptions, whether or not accurate.

Mortgage-backed securities risk – these fixed-income securities represent the right to receive a portion of principal and/or interest payments made on a pool of residential or commercial mortgage loans. When interest rates fall, borrowers may refinance or otherwise repay principal on their loans earlier than scheduled. When this happens, certain types of mortgage-backed securities will be paid off more quickly than originally anticipated and a Fund will have to invest the proceeds in securities with lower yields. This risk is known as “prepayment risk.” Prepayment might also occur due to foreclosures on the underlying mortgage loans. When interest rates rise, certain types of mortgage-backed securities will be paid off more slowly than originally anticipated and the value of these securities will become more sensitive to interest rate changes and will fall if the market perceives the securities’ interest rates to be too low for a longer-term investment. This risk is known as “extension risk.” Because of prepayment risk and extension risk, mortgage-backed securities react differently to changes in interest rates than other fixed-income securities. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain mortgage-backed securities. 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 to 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.

Preferred stock risk – a preferred stock may decline in price, or fail to pay dividends when expected, because the issuer experiences a decline in its financial status. In addition to this credit risk, investment in preferred stocks involves certain other risks, including skipping or deferring distributions, and redemption in the event of certain legal or tax changes or at the issuer’s call. Preferred stocks are also subordinated to bonds and other debt instruments in a company’s capital structure in terms of priority to corporate income and liquidation payments, and therefore will be subject to greater credit risk than those debt instruments. Preferred stocks may be significantly less liquid than many other securities, such as U.S. government securities, corporate debt or common stock.

Prepayment and call risk – certain bonds will be paid off by the issuer more quickly than anticipated. If this happens, the Fund may be required to invest the proceeds in securities with lower yields.

Smaller company risk – in general, stocks of smaller companies trade in lower volumes, may be less liquid, and are subject to
