Additional Information About the Risks

All mutual funds involve risk - some more than others - and there is always the chance that you could lose money or not earn as much as you hope. A Fund’s risk profile is largely a factor of the principal securities in which it invests and investment techniques that it uses. Below is a discussion of the risks associated with certain of the types of securities in which the Funds may invest and certain of the investment practices that the Funds may use. For more information about these and other types of securities and investment techniques that may be used by the Funds, see the SAI.

Many of the investment techniques and strategies discussed in this Prospectus and in the SAI are discretionary which means that the Adviser or sub-adviser can decide whether to use them. The Funds may invest in these securities or use these techniques as part of the Funds’ principal investment strategies. However, the Adviser or sub-adviser may also use these investment techniques or make investments in securities that are not a part of the Funds’ principal investment strategies.

The discussions below expand on the risks included in a Fund’s summary section of the Prospectus. Please see the SAI for a further discussion of the principal and other investment strategies employed by each Fund.

Call.   During periods of falling interest rates, a bond issuer may “call” or repay its high-yielding bond before the bond’s maturity date. If forced to invest the unanticipated proceeds at lower interest rates, a fund would experience a decline in income.

Company.   The price of a given company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Credit.   Prices of bonds and other debt securities can fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay altogether.

Credit for Floating Rate Loan Funds.   The value of a fund’s shares, and the fund’s ability to pay dividends, is dependent upon the performance of the assets in its portfolio. Prices of a fund’s investments can fall if the actual or perceived financial health of the borrowers on, or issuers of, such investments deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the borrower or issuer could be late in paying interest or principal, or could fail to pay altogether.

In the event a borrower fails to pay scheduled interest or principal payments on an investment held by a fund, the fund will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid by a fund and likely lead to a decline in the net asset value of the fund’s shares.

A fund generally invests in floating rate loans that are senior in the capital structure of the borrower or issuer, and that are secured with specific collateral. Loans that are senior and secured generally involve less risk than unsecured or subordinated debt and equity instruments of the same borrower because the payment of principal and interest on senior loans is an obligation of the borrower that, in most instances, takes precedence over the payment of dividends or the return of capital to the borrower’s shareholders, and payments to bond holders; and because of the collateral supporting the repayment of the debt instrument. However, the value of the collateral may not equal a fund’s investment when the debt instrument is acquired or may decline below the principal amount of the debt instrument subsequent to the fund’s investment. Also, to the extent that collateral consists of stocks of the borrower, or its subsidiaries or affiliates, a fund bears the risk that the stocks may decline in value, be relatively illiquid, or may lose all or substantially all of their value, causing the fund’s investment to be undercollateralized. Therefore, the liquidation of the collateral underlying a floating rate loan in which a fund has invested, may not satisfy the borrower’s obligation to the fund in the event of non-payment of scheduled interest or principal, and the collateral may not be able to be readily liquidated.

In the event of the bankruptcy of a borrower or issuer, a fund could experience delays and limitations on its ability to realize the benefits of the collateral securing the fund’s investment. Among the risks involved in a bankruptcy are assertions that the pledge of collateral to secure a loan constitutes a fraudulent conveyance or preferential transfer that would have the effect of nullifying or subordinating a fund’s rights to the collateral.

The Floating Rate Debt in which a fund invests is generally rated lower than investment-grade credit quality, i.e. , rated lower than Baa3 by Moody’s Investors Service, Inc. (“Moody’s”) or BBB- by Standard & Poor’s Ratings Services (“S&P”), or have been made to borrowers who have issued debt securities that are rated lower than investment-grade in quality or, if unrated, would be rated lower than investment-grade credit quality. A fund’s investments in lower than investment-grade floating rate loans will generally be rated at the time of purchase between B3 and Ba1 by Moody’s, B- and BB+ by S&P or, if not rated, would be of similar credit quality. Investment decisions for a fund will be based largely on the credit analysis performed by the sub-adviser, and not on rating agency evaluation. This analysis may be difficult to perform. Information about a loan and its borrower generally is not in the public domain. Many borrowers have not issued securities to the public and are not subject to reporting requirements under federal securities laws. Generally, however, borrowers are required to provide financial information to lenders and information may be available from other loan market participants or agents that originate or administer loans.

Credit Default Swaps.   A fund may enter into credit default swaps, either as a buyer or a seller of the swap. As a buyer of the swap, a fund pays a fee to protect against the risk that a security held by the fund will default. As a seller of the swap, a fund receives payment(s) in return for its obligation to pay the counterparty an agreed upon value of a security in the event of a default of the security issuer. Credit default swaps are largely unregulated and susceptible to liquidity, credit, and counterparty risks.

Currency.   To the extent that a fund invests directly in foreign currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those currencies will decline in value relative to the U.S. dollar or, in the case of hedging positions, that the U.S. dollar will decline in value relative to the currency being hedged. Currency rates may fluctuate significantly over short periods of time. Currency rates may be affected by changes in interest rates, intervention (or the failure to intervene) by U.S. or foreign governments, central banks or supranational entities such as the International Monetary Fund, by the imposition of currency controls, or other political or economic developments in the United States or abroad. As a result, a fund’s investments in foreign currency or foreign currency-denominated securities may reduce the value of the fund’s assets.

Demand for Loans.   The loan market, as represented by the S&P/LSTA Leveraged Loan Index, experienced significant growth in terms of number and aggregate volume of loans outstanding since the inception of the index in 1997. In 1997, the total amount of loans in the market aggregated less than $10 billion. By April of 2000, it had grown to over $100 billion, and by July of 2007 the market had grown to over $500 billion. The size of the market peaked in November of 2008 at $594 billion. During this period, the demand for loans and the number of investors participating in the loan market also increased significantly.

Since 2008, the market has contracted, characterized by limited new loan issuance and payoffs of outstanding loans. From the peak in 2008 through February 2012, the overall size of the loan market contracted by approximately 13%. The number of market participants also decreased during that period. Although the number of new loans being issued in the market in 2012 is increasing, there can be no assurance that the size of the loan market, and the number of participants, will return to earlier levels.

An increase in demand for loans may benefit a fund by providing increased liquidity for such loans and higher sales prices, but it may also adversely affect the rate of interest payable on such loans acquired by the fund and the rights provided to the fund under the terms of the applicable loan agreement, and may increase the price of loans that the fund wishes to purchase in the secondary market. A decrease in the demand for loans may adversely affect the price of loans in a fund’s portfolio, which could cause the fund’s net asset value to decline.

Derivative Instruments.   Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in interest rates and liquidity risk. The use of certain derivatives may also have a leveraging effect which may increase the volatility of a fund and reduce its returns. Generally, derivatives are sophisticated financial instruments whose performance is derived, at least in part, from the performance of an underlying asset or assets. Derivatives include, among other things, swap agreements, options, forwards and futures. The investment of a fund’s assets required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the fund; therefore, the purchase of certain derivatives may have an economic leveraging effect on the fund; thus exaggerating any increase or decrease in the net asset value of the fund. Investments in derivatives are generally negotiated over-the-counter with a single counterparty and as a result are subject to credit risks related to the counterparty’s ability to perform its obligations and further that any deterioration in the counterparty’s creditworthiness could adversely affect the value of the derivative. In addition, derivatives and their underlying securities may experience periods of illiquidity which could cause a fund to hold a security it might otherwise sell, or to sell a security it otherwise might hold at inopportune times or for prices that do not reflect current market value. A fund’s adviser or sub-adviser might imperfectly judge the direction of the market. For instance, if a derivative is used as a hedge to offset investment risk in another security, the hedge might not correlate to the market’s movements and may have unexpected or undesired results such as a loss or a reduction in gains to a fund.

Equity Securities Incidental to Investments in Loans.   The value of equity securities in which a fund invests may be affected more rapidly, and to a greater extent, by company-specific developments and general market conditions. These risks may increase fluctuations in a fund’s net asset value. A fund may frequently possess material non-public information about a borrower as a result of its ownership of a loan of such borrower. Because of prohibitions on trading in securities of issuers while in possession of such information a fund might be unable to enter into a transaction in a security of such a borrower when it would otherwise be advantageous to do so.

Foreign Investments/Developing and Emerging Markets.   To the extent a fund invests in securities of issuers in markets outside the United States, its share price may be more volatile than if it invested in securities of issuers in the U.S. market due to, among other things, the following factors: comparatively unstable political, social and economic conditions, and limited or ineffectual judicial systems; comparatively small market sizes, making securities less liquid and securities prices more sensitive to the movements of large investors and more vulnerable to manipulation; governmental policies or actions, such as high taxes, restrictions on currency movements, replacement of currency, potential for default on sovereign debt, trade or diplomatic disputes, creation of monopolies, and the seizure of private property through confiscatory taxation and expropriation or nationalization of company assets; incomplete, outdated, or unreliable information about securities issuers due to less stringent market regulation and accounting standards; comparatively undeveloped markets and weak banking and financial systems; market inefficiencies, such as higher transaction costs, and administrative difficulties, such as delays in processing transactions; and fluctuations in foreign currency exchange rates, which could reduce gains or widen losses. In addition, foreign taxes could reduce the income available to distribute to shareholders, and special U.S. tax considerations could apply to foreign investments. Depositary receipts are subject to risks of foreign investments and might not always track the price of the underlying foreign security.

Foreign investment risks typically are greater in developing and emerging markets than in developed markets, for such reasons as social or political unrest, heavy economic dependence on agriculture or exports (particularly commodities), undeveloped or overburdened infrastructures, vulnerability to natural disasters, significant and unpredictable government intervention in markets or the economy, currency devaluations, runaway inflation, environmental problems, and business practices that depart from norms for developed countries and less developed or liquid markets for securities generally.

High-Yield Securities.   Investments rated below investment-grade (or of similar quality if unrated) are known as “high-yield securities” or “junk bonds.” High-yield securities are subject to greater levels of credit and liquidity risks. High-yield securities are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments. Investments in high-yield debt securities generally provide greater income and increased opportunity for capital appreciation than investments in higher quality debt securities, but they also typically entail greater potential price volatility and principal

Interest in Loans.   The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A large rise in interest rates could increase this risk. Although loans are generally fully collateralized when purchased, the collateral may become illiquid or decline in value. Many loans themselves carry liquidity and valuation risks.

Interest Rate.   With bonds and other fixed rate debt securities, a rise in interest rates generally causes values to fall; conversely, values generally rise as interest rates fall. The higher the credit quality of the security, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk.

Interest Rate for Floating Rate Loan Funds.   Changes in short-term market interest rates will directly affect the yield on the shares of a fund whose investments are normally invested in Floating Rate Debt. If short-term market interest rates fall, the yield on the fund’s shares will also fall. Conversely, when short-term market interest rates rise, because of the lag between changes in such short-term rates and the resetting of the floating rates on the Floating Rate Debt in a fund’s portfolio, the impact of rising rates will be delayed to the extent of such lag. The impact of market interest rate changes on a fund’s yield will also be affected by whether, and the extent to which, the Floating Rate Debt in the fund’s portfolio is subject to floors on the LIBOR base rate on which interest is calculated for such loans (a “LIBOR floor”). So long as the base rate for a loan remains under the LIBOR floor, changes in short-term interest rates will not affect the yield on such loans. In addition, to the extent that the interest rate spreads on Floating Rate Debt in a fund’s portfolio experience a general decline, the yield on the fund’s shares will fall and the value of the fund’s assets may decrease, which will cause the fund’s net asset value to decrease. With respect to a fund’s investments in fixed rate instruments, a rise in interest rates generally causes values to fall. The values of fixed rate securities with longer maturities or duration are more sensitive to changes in interest rates.

Investment Model.   The manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. The proprietary models used by a manager to evaluate securities or securities markets are based on the manager’s understanding of the interplay of market factors and do not assure successful investment. The markets, or the price of individual securities, may be affected by factors not foreseen in developing the models.

Leverage for Floating Rate Funds.   Certain transactions and investment strategies may give rise to leverage. Such transactions and investment strategies include, among others: borrowing and the use of forward-commitment transactions. The use of certain derivatives may also create leveraging risk. The use of leverage may increase a fund’s expenses and increase the impact of the fund’s other risks. The use of leverage may exaggerate any increase or decrease in the net asset value of a fund. To mitigate leveraging risk, a fund will segregate liquid assets or otherwise cover the fund’s obligation under transactions such as reverse repurchase agreements; when issued and delayed delivery securities, and forward commitment transactions. The use of leverage may cause a fund to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet segregation requirements resulting in increased volatility of returns. Leverage, including borrowing, may cause a fund to be more volatile than if the fund had not been leveraged.

Limited Secondary Market for Floating Rate Loans.   Although the re-sale, or secondary market for floating rate loans has grown substantially over the past decade, both in overall size and number of market participants, there is no organized exchange or board of trade on which floating rate loans are traded. Instead, the secondary market for floating rate loans is a private, unregulated inter-dealer or inter-bank re-sale market.

Floating rate loans usually trade in large denominations. Trades can be infrequent and the market for floating rate loans may experience substantial volatility. In addition, the market for floating rate loans has limited transparency so that information about actual trades may be difficult to obtain. Accordingly, some of the floating rate loans in which a fund invests will be relatively illiquid.

In addition, the floating rate loans in which a fund invests may require the consent of the borrower and/or the agent prior to sale or assignment. These consent requirements can delay or impede a fund’s ability to sell floating rate loans and can adversely affect the price that can be obtained. A fund may have difficulty disposing of floating rate loans if it needs cash to repay debt, to fund redemptions, to pay dividends, to pay expenses or to take advantage of new investment opportunities.

These considerations may cause a fund to sell floating rate loans at lower prices than it would otherwise consider to meet cash needs or cause the fund to maintain a greater portion of its assets in money market instruments than it would otherwise, which could negatively impact performance. A fund may seek to avoid the necessity of selling assets to meet redemption requests or liquidity needs by the use of borrowings. Such borrowings, even though they are for the purpose of satisfying redemptions or meeting liquidity needs and not to generate leveraged returns, nevertheless would produce leverage and the risks that are inherent in leverage. However, there can be no assurance that sales of floating rate loans at such lower prices can be avoided.

From time to time, the occurrence of one or more of the factors described above may create a cascading effect where the market for debt instruments (including the market for floating rate loans) first experiences volatility and then decreased liquidity. Such conditions, or other similar conditions, may then adversely affect the value of floating rate loans and other instruments, widening spreads against higher-quality debt instruments, and making it harder to sell floating rate loans at prices at which they have historically or recently traded, thereby further reducing liquidity. For example, during the global liquidity crisis in the second half of 2008, the average price of loans in the S&P/LSTA Leverage Loan Index declined by 32% (which included a decline of 3.06% on a single day) prior to rebounding substantially in 2009 and into 2011. Declines in a fund’s share price or other market developments (which could be more severe than these prior declines) may lead to increased redemptions, which could cause the fund to have to sell floating rate loans and other instruments at disadvantageous prices and inhibit the ability of the fund to retain its assets in the hope of greater stabilization in the secondary markets. In addition, these or similar circumstances could cause a fund to sell its highest quality and most liquid floating rate loans and other investments in order to satisfy an initial wave of redemptions while leaving the fund with a remaining portfolio of lower-quality and less liquid investments. In anticipation of such circumstances, a fund may also need to maintain a larger portion of its assets in liquid instruments than usual. However, there can be no assurance that a fund will foresee the need to maintain greater liquidity or that actual efforts to maintain a larger portion of assets in liquid investments would successfully mitigate the foregoing risks.

Liquidity.   If a security is illiquid, the adviser or sub-adviser might be unable to sell the security at a time when a fund’s manager might wish to sell, and the security could have the effect of decreasing the overall level of the fund’s liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, which could vary from the amount a fund could realize upon disposition. A fund may make investments that become less liquid in response to market developments or adverse investor perception. A fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the fund.

Liquidity for Floating Rate Loan Funds.   If a loan is illiquid, a fund might be unable to sell the loan at a time when a fund’s manager might wish to sell, thereby having the effect of decreasing the fund’s overall level of liquidity. Further, as described in Valuation of Loans below, the lack of an established secondary market may make it more difficult to value illiquid loans, which could result in floating rate loans being assigned values which prove to be higher than the amounts that a fund ultimately realizes upon its actual sales of those loans. A fund may make investments that become less liquid in response to market developments or adverse investor perception, including but not limited to, those circumstances described in Limited Secondary Market for Floating Rate Loans above. A fund could lose money if it cannot sell a loan at the time and price that would be most beneficial to the fund.

Market.   Stock prices may be volatile and are affected by the real or perceived impacts of such factors as economic conditions and political events. The stock market tends to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods.

Market Capitalization.   Stocks fall into three broad market capitalization categories - large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-sized companies causing a fund

Mortgage- and/or Asset-Backed Securities.   Defaults on or low credit quality or liquidity of the underlying assets of the asset-backed (including mortgage-backed) securities held by a fund may impair the value of the securities. There may be limitations on the enforceability of any security interest granted with respect to those underlying assets. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of fixed-income securities. Because of prepayment risk and extension risk, small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed securities. The value of longer-term securities generally changes more in response to changes in interest rates than shorter term securities.

During an economic downturn, the mortgages, commercial or consumer loans, trade or credit card receivables, installment purchase obligations, leases, or other debt obligations underlying an asset-backed security may experience an increase in defaults as borrowers experience difficulties in repaying their loans which may cause the valuation of such securities to be more volatile and may reduce the value of such securities. These risks are particularly heightened for investments in asset-backed securities that contain sub-prime loans which are loans made to borrowers with weakened credit histories and often have higher default rates.

Municipal Obligations.   The municipal market in which a fund invests is volatile and can be significantly affected by adverse tax, legislative, or political changes and the financial condition of the issuers of municipal securities. Municipal revenue obligations are backed by the revenues generated from a specific project or facility and include industrial development bonds and private activity bonds. Private activity and industrial development bonds are dependent on the ability of the facility’s user to meet its financial obligations and the value of any real or personal property pledged as security for such payment. Many municipal securities are issued to finance projects relating to education, health care, transportation and utilities. Conditions in those sectors may affect the overall municipal market. In addition, municipal securities backed by current or anticipated revenues from a specific project or specific asset may be adversely affected by the discontinuance of the taxation supporting the project or asset or the inability to collect revenues for the project or from assets. If an issuer of a municipal security does not comply with applicable tax requirements, interest from the security may become taxable and the security could decline in value.

Other Investment Companies.   The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Because a fund may invest in other investment companies, you will pay a proportionate share of the expenses of that other investment company (including management fees, administration fees, and custodial fees) in addition to the expenses of the fund.

Other investment companies include ETFs and Holding Company Depositary Receipts (“HOLDRs”), among others. ETFs are exchange-traded investment companies that are, in many cases, designed to provide investment results corresponding to an index. The value of the underlying securities can fluctuate in response to activities of individual companies or in response to general market and/or economic conditions. Additional risks of investments in ETFs include: (i) the market price of an ETF’s shares may trade at a discount to its net asset value; (ii) an active trading market for an ETF’s shares may not develop or be maintained; or (iii) trading may be halted if the listing exchanges’ officials deem such action appropriate, the shares are delisted from the exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts trading generally. Because HOLDRs concentrate in the stocks of a particular industry, trends in that industry may have a dramatic impact on their value.

Prepayment and Extension.   Prepayment risk is the risk that principal on mortgages or other loan obligations underlying a security may be repaid prior to the stated maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Extension risk is the risk that an issuer will exercise its right to repay principal on an obligation held by a fund later than expected, which may decrease the value of the obligation and prevent the fund from investing expected repayment proceeds in securities paying yields higher than the yields paid by the securities that were expected to be repaid.

Prepayment and Extension for Floating Rate Loans.   Prepayment risk is the risk that principal on a debt obligation may be repaid earlier than anticipated. Floating rate loans typically do not have call protection and may be prepaid partially or in full at any time without penalty. If a floating rate loan is prepaid, a fund may realize proceeds that are less than the value that had been assigned to the loan and/or may be forced to reinvest the proceeds in assets with lower yields than the loan that was repaid. For a fund’s fixed rate investments, prepayment risk is the risk that principal on mortgages or other loan obligations underlying a security may be repaid prior to the stated maturity date, which may reduce the market value of the security and the anticipated yield-to-maturity. Extension risk is the risk that an issuer will exercise its right to repay principal on a fixed rate obligation held by a fund later than expected, which may decrease the value of the obligation and may prevent the fund from investing expected repayment proceeds in securities paying yields higher than the yields paid by the securities that were expected to be repaid.

Securities Lending.   Securities lending involves two primary risks: “investment risk” and “borrower default risk.” Investment risk is the risk that a fund will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that a fund will lose money due to the failure of a borrower to return a borrowed security in a timely manner.

To generate additional income, a fund may lend securities to financial institutions that are believed to be creditworthy by the adviser. When lending securities, a fund will receive cash or U.S. government securities as collateral.

When a fund lends its securities, it is responsible for investing the cash it receives as collateral from the borrower, and the fund could incur losses in connection with the investment of such collateral, often referred to as “investment risk.” A fund will minimize investment risk by limiting the investment of cash collateral to high-quality instruments of short maturity.

A fund may also lose money from the failure of a borrower to return a borrowed security in a timely manner, often referred to as “borrower default risk.” In the event of a borrower default, a fund will be protected to the extent the fund is able to exercise its rights in the collateral promptly and the value of such collateral is sufficient to purchase replacement securities. In addition, a fund will be protected by its securities lending agent, which has agreed to indemnify the fund from losses resulting from borrower default.

U.S. Government Securities and Obligations.   U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies or government-sponsored enterprises. U.S. government securities are subject to market and interest rate risk, and may be subject to varying degrees of credit risk. Some U.S. government securities are backed by the full faith and credit of the U.S. government and are guaranteed as to both principal and interest by the U.S. Treasury. These include direct obligations of the U.S. Treasury such as U.S. Treasury notes, bills and bonds, as well as indirect obligations including certain securities of the Government National Mortgage Association, the Small Business Administration, and the Farmers Home Administration, among others. Other U.S. government securities are not direct obligations of the U.S. Treasury, but rather are backed by the ability to borrow directly from the U.S. Treasury, including certain securities of the Federal Financing Bank, the Federal Home Loan Bank, and the U.S. Postal Service. Still other agencies and instrumentalities are supported solely by the credit of the agency or instrumentality itself and are neither guaranteed nor insured by the U.S. government. These include securities issued by the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, and the Federal Farm Credit Bank, among others. Consequently, the investor must look principally to the agency issuing or guaranteeing the obligation for ultimate repayment. No assurance can be given that the U.S. government would provide financial support to such agencies if it is not obligated to do so by law. U.S. government securities may be subject to varying degrees of credit risk and all U.S. government securities may be subject to price declines due to changing interest rates. Securities directly supported by the full faith and credit of the U.S. government have less credit risk.

Valuation of Loans.   A fund values its assets daily. However, because the secondary market for floating rate loans is limited, it may be difficult to value loans. Reliable market value quotations may not be readily available for some loans and valuation of such loans may require more research than for liquid securities. In addition, elements of judgment may play a greater role in valuation of loans than for securities with a more developed secondary market because there is less reliable, objective market value data available. In addition, if a fund purchases a relatively large portion of a loan, the limitations of the secondary market may inhibit the fund from selling a portion of the loan and reducing its exposure to a borrower when the adviser or sub-adviser deems it advisable to do so. Even if a fund itself does not own a relatively large portion of a particular loan, the fund, in combination with other similar accounts under management by the same portfolio managers, may own large portions of loans. The combination of holdings could create similar risks if and when the portfolio managers decide to sell those loans. These risks could include, for example, the risk that the sale of an initial

Zero-Coupon Bonds and Pay-in-Kind Securities.   Zero-coupon bonds and pay-in-kind securities may be subject to greater fluctuations in price from interest rate changes than conventional interest-bearing securities. A fund may have to pay out the imputed income on zero-coupon bonds without receiving the actual cash currency. The values of interest-only and principal-only mortgage-related securities also are subject to prepayment risk and interest rate risks.

Additional Risks

The discussion below also includes risks that are not considered to be principal risks of a Fund, but are considered to be relevant to each Fund.

Counterparty.   The entity with which a fund conducts portfolio-related business (such as trading or securities lending), or that underwrites, distributes or guarantees investments or agreements that the fund owns or is otherwise exposed to, may refuse or may become unable to honor its obligations under the terms of a transaction or agreement. As a result, that fund may sustain losses and be less likely to achieve its investment objective. These risks may be greater when engaging in over-the-counter transactions.

Duration.   One measure of risk for fixed-income securities is duration. Duration measures the sensitivity of a bond’s price to interest rate movements and is one of the tools used by a portfolio manager in selection of fixed-income securities. Historically, the maturity of a bond was also used as a proxy for the sensitivity of a bond’s price to changes in interest rates, otherwise known as a bond’s interest rate risk or volatility. According to this measure, the longer the maturity of a bond, the more its price will change for a given change in market interest rates. However, this method ignores the amount and timing of all cash flows from the bond prior to final maturity. Duration is a measure of average life of a bond on a present value basis which was developed to incorporate a bond’s yield, coupons, final maturity and call features into one measure. For point of reference, the duration of a noncallable 7% coupon bond with a remaining maturity of 5 years is approximately 4.5 years and the duration of a noncallable 7% coupon bond with a remaining maturity of 10 years is approximately 8 years. Material changes in interest rates may impact the duration calculation.

Increase in Expenses.   Your actual cost of investing in a fund may be higher or lower than the expenses shown in the fund’s Annual Fund Operating Expenses for a variety of reasons. For example, expense ratios may be higher than those shown if the fund’s assets decrease. The fund’s assets may decrease and fund expense ratios increase for many reasons, including volatility in the fund’s net asset value caused by volatility in the secondary markets for assets in which the fund invests.

Investment by Other Funds.   Various other mutual funds and/or funds-of-funds, including some ING funds, may invest in a fund. If investments by these other funds result in large inflows or outflows of cash from the fund, the fund’s performance or realization of capital gains could be affected. While it is very difficult to predict the overall impact of these transactions over time, there could be adverse effects on portfolio management. For example, these transactions could also increase transaction costs or portfolio turnover. The adviser or sub-adviser will monitor transactions by the funds-of-funds and will attempt to minimize any adverse effects on a fund and funds-of-funds as a result of these transactions.

Manager.   A fund is subject to manager risk because it is an actively managed investment portfolio. The adviser, the sub-adviser or each individual portfolio manager will apply investment techniques and risk analyses in making investment decisions for a fund, but there can be no guarantee that these will produce the desired results.

PORTFOLIO HOLDINGS INFORMATION

Portfolio Holdings Information

A description of each Fund’s policies and procedures regarding the release of portfolio holdings information is available in the Funds’ SAI. Portfolio holdings information can be reviewed online at www.INGInvestment.com.

Additional Information About Exchanges

Fees and expenses differ among ING Funds and among share classes of the same Fund. Please read the prospectus for the ING Fund and share class you are interested in prior to exchanging into that ING Fund or share class.

An exchange of shares of a Fund for shares of another ING Fund is treated as a sale and purchase of shares and may result in the recognition of a gain or loss for federal and state income tax purposes. For exchanges among ING Funds and among classes of shares of the same Fund, you should consult your own tax advisor for advice about the particular federal, state, and local tax consequences to you of the exchange. The total value of shares being exchanged must at least equal the minimum investment requirement of the ING Fund into which they are being exchanged.

If you exchange into ING Senior Income Fund, your ability to sell or liquidate your investment will be limited. ING Senior Income Fund is a closed-end interval fund and does not redeem its shares on a daily basis. It is not expected that a secondary market for ING Senior Income Fund’s shares will develop, so you will not be able to sell them through a broker or other investment professional. To provide a measure of liquidity, ING Senior Income Fund will normally make monthly repurchase offers for not less than 5% of its outstanding common shares. If more than 5% of ING Senior Income Fund’s common shares are tendered, you may not be able to completely liquidate your holdings in any one month. You also would not have liquidity between these monthly repurchase dates. Investors exercising the exchange privilege into ING Senior Income Fund should carefully review the prospectus of that fund. Investors may obtain a copy of the ING Senior Income Fund prospectus or any other ING Fund prospectus by calling 1-800-992-0180 or by going to www.INGInvestment.com.

In addition to each Fund available in this Prospectus, the Distributor offers many other funds. Shareholders exercising the exchange privilege with any other ING Fund should carefully review the prospectus of that fund before exchanging their shares. Investors may obtain a copy of a prospectus of any ING Fund not discussed in this Prospectus by calling 1-800-992-0180 or by going to www.INGInvestment.com.

You will automatically have the ability to request an exchange between ING Funds by calling a Shareholder Services Representative unless you mark the box on the Account Application that indicates that you do not wish to have the telephone exchange privilege. A Fund may change or cancel its exchange policies at any time, upon 60 days’ prior notice to shareholders.

Systematic Exchange Privilege

Subject to the information and limitations outlined above, you may elect to have a specified dollar amount of shares systematically exchanged, monthly, quarterly, semi-annually, or annually from your account to an identically registered account in the same class of any other open-end ING Fund, except for ING Corporate Leaders Trust Fund. This exchange privilege may be modified at any time or terminated upon 60 days’ prior written notice to shareholders.

FREQUENT TRADING - MARKET TIMING

The Funds are intended for long-term investment and not as short-term trading vehicles. Accordingly, organizations or individuals that use market timing investment strategies should not purchase shares of the Funds. The Funds reserve the right, in their sole discretion and without prior notice, to reject, restrict, or refuse purchase orders whether directly or by exchange, including purchase orders that have been accepted by a shareholder’s or retirement plan participant’s intermediary, that the Funds determine not to be in the best interest of the Funds. Such action may include, but not be limited to: rejecting additional purchase orders, whether directly or by exchange; extending settlement of a redemption up to seven days; rejecting all purchase orders from broker-dealers or their registered representatives suspected of violating the Funds’ frequent trading policy; or termination of the selling group agreement or other agreement with broker-dealers or other financial intermediaries associated with frequent trading. The Funds will not be liable for any loss resulting from rejected orders or other actions as described above.

The Funds believe that market timing or frequent, short-term trading in any account, including a retirement plan account, is not in the best interest of the Funds or their shareholders. Due to the disruptive nature of this activity, it can adversely affect the ability of the Adviser or Sub-Adviser (if applicable) to invest assets in an orderly, efficient manner. Frequent trading can raise Fund expenses through: increased trading and transaction costs; increased administrative costs; and lost opportunity costs. This in turn can have an adverse effect on Fund performance.

Funds that invest in foreign securities may present greater opportunities for market timers and thus be at a greater risk for excessive trading. If an event occurring after the close of a foreign market, but before the time a Fund computes its current NAV, causes a change in the price of the foreign security and such price is not reflected in the Fund’s current NAV, investors may attempt to take advantage of anticipated price movements in securities held by the Fund based on such pricing discrepancies. This is often referred to as “price arbitrage.” Such price arbitrage opportunities may also occur in Funds which do not invest in foreign securities. For example, if trading in a security held by a Fund is halted and does not resume prior to the time the Fund calculates its NAV such “stale pricing” presents an opportunity for investors to take advantage of the pricing discrepancy. Similarly, Funds that hold thinly-traded securities, such as certain small-capitalization securities, may be exposed to varying levels of pricing arbitrage. The Funds have adopted fair valuation policies and procedures intended to reduce the Funds’ exposure to price arbitrage, stale pricing and other potential pricing discrepancies. Currently, Interactive Data Pricing and Reference Data, Inc. provides such services to the Funds. However, to the extent that a Fund does not immediately reflect these changes in market conditions, short-term trading may dilute the value of the Funds’ shares which negatively affects long-term shareholders.

The Funds’ Board has adopted policies and procedures designed to deter frequent, short-term trading in shares of the Funds. In general, shareholders may make exchanges among their accounts with ING Funds once every thirty (30) days. However, the Funds prohibit frequent trading. The Funds have defined frequent trading as follows:

• Any shareholder or financial adviser who initiated exchanges among all their accounts with the Funds within thirty (30) calendar days of a previous exchange. All exchanges occurring on the same day for all accounts (individual, IRA, 401(k), etc.) beneficially owned by the same shareholder will be treated as a single transaction for purposes of this policy;
• Trading deemed harmful or excessive by the Funds (including but not limited to patterns of purchases and redemptions), in their sole discretion; and
• Trades initiated by financial advisers, among multiple shareholder accounts, that in the aggregate are deemed harmful or excessive.

The following transactions are excluded when determining whether trading activity is excessive:

• Purchases and sales of Fund shares in the amount of $5,000 or less;
• Transfers associated with systematic purchases or redemptions;
• Purchases and sales of funds that affirmatively permit short-term trading;
• Rebalancing to facilitate fund-of-fund arrangements or the Funds’ systematic exchange privileges;
• Purchases or sales initiated by ING Funds; and
• Transactions subject to the trading policy of an intermediary that the Funds deem materially similar to the Funds’ policy.

Please note that while money market funds permit short-term trading, an exchange between a money market fund and another fund that does not permit short-term trading will count as an exchange for purposes of this policy.

If a violation of the policy is identified, the following action will be taken:

• Upon the first violation of this policy in a calendar year, purchase and exchange privileges shall be suspended for ninety (90) days. For example, if an exchange is initiated on February 1st, and a second exchange is initiated on February 15th, trading privileges shall be suspended for ninety (90) days from February 1st.
• Upon a second violation in a calendar year, purchase and exchange privileges shall be suspended for one hundred and eighty (180) days.
• No purchases or exchanges will be permitted in the account and all related accounts bearing the same Tax ID or equivalent identifier.

On the next business day following the end of the ninety (90) or one hundred and eighty (180) day suspension, any trading restrictions placed on the account(s) shall be removed.

The Funds reserve the right to modify this policy at any time without prior notice.

Although the restrictions described above are designed to discourage frequent, short-term trading, none of them alone, nor all of them taken together, can eliminate the possibility that frequent, short-term trading activity in the Funds will occur. Moreover, in enforcing such restrictions, the Funds are often required to make decisions that are inherently subjective. The Funds strive to make these decisions to the best of their abilities in a manner that they believe is in the best interest of shareholders.

Shareholders may invest in the Funds through omnibus account arrangements with financial intermediaries. Omnibus accounts permit intermediaries to aggregate their clients’ transactions and in these circumstances, the identity of the shareholder is often unknown. Such intermediaries include broker-dealers, banks, investment advisers, record keepers, retirement plans, and fee-based accounts such as wrap fee programs. Omnibus accounts generally do not identify customers’ trading activity on an individual basis. The Funds’ Administrator has agreements in place with intermediaries which require such intermediaries to provide detailed account information, including trading history, upon request of the Funds. There is no assurance that the Funds’ Administrator will request such information with sufficient frequency to detect or deter excessive trading or that review of such information will be sufficient to detect or deter excessive trading in omnibus accounts effectively.

In some cases, the Funds will rely on the intermediaries’ excessive trading policies and such policies shall define the trading activity in which the shareholder may engage. This shall be the case where the Funds are used in certain retirement plans offered by affiliates. With trading information received as a result of the agreements, the Funds may make a determination that certain trading activity is harmful to the Funds and their shareholders even if such activity is not strictly prohibited by the intermediaries’ excessive trading policy. As a result, a shareholder investing directly or indirectly in one of the Funds may have their trading privileges suspended without violating the stated excessive trading policy of the intermediary.

PAYMENTS TO FINANCIAL INTERMEDIARIES

ING mutual funds are distributed by the Distributor. The Distributor is a broker-dealer that is licensed to sell securities. The Distributor generally does not sell directly to the public but sells and markets its products through intermediaries such as other broker-dealers. Each ING mutual fund also has an investment adviser which is responsible for managing the money invested in each of the mutual funds. Both of these entities (collectively, “ING”) may compensate an intermediary for selling ING mutual funds.

Only persons licensed with FINRA as a registered representative (often referred to as a broker or financial adviser) and associated with a specific broker-dealer may sell an ING mutual fund to you. The Distributor has agreements in place with each broker-dealer selling a Fund defining specifically what those broker-dealers will be paid for the sale of a particular ING mutual fund. Those broker-dealers then pay the registered representative who sold you the mutual fund some or all of what they receive from ING. They may receive a payment when the sale is made and can, in some cases, continue to receive payments while you are invested in the mutual fund.

The Funds’ Adviser or the Distributor, out of its own resources and without additional cost to a Fund or its shareholders, may provide additional cash or non-cash compensation to intermediaries selling shares of a Fund, including affiliates of the Adviser and the Distributor. These amounts would be in addition to the distribution payments made by a Fund under the distribution agreements. The payments made under these arrangements are paid by the Adviser or the Distributor. Additionally, if a fund is not sub-advised or is sub-advised by an ING entity, ING may retain more revenue than on those funds it must pay to have sub-advised by non-affiliated entities. Management personnel of ING may receive additional compensation if the overall amount of investments in funds advised by ING meets certain target levels or increases over time.

The Distributor may pay, from its own resources, additional fees to these broker-dealers or other financial institutions including affiliated entities. These additional fees paid to intermediaries may take the following forms: (1) a percentage of that entity’s customer assets invested in ING mutual funds; (2) a percentage of that entity’s gross sales; or (3) some combination of these payments. These payments may, depending on the broker-dealer’s satisfaction of the required conditions, be periodic and may be up to: (1) 0.30% per annum of the value of a Fund’s shares held by the broker-dealer’s customers; or (2) 0.30% of the value of a Fund’s shares sold by the broker-dealer during a particular period. In accordance with these practices, if that initial investment averages a value of $10,000 over the year, the Distributor could pay a maximum of $30 on those assets. If you invested $10,000, the Distributor could pay a maximum of $30 for that sale.

The Funds’ Adviser or the Distributor may provide additional cash or non-cash compensation to third parties selling our mutual funds including affiliated companies. This may take the form of cash incentives and non-cash compensation and may include, but is not limited to: cash; merchandise; trips; occasional entertainment; meals or tickets to a sporting event; client appreciation events; payment for travel expenses (including meals and lodging) to pre-approved training and education seminars; and payment for advertising and sales campaigns. The Distributor may also pay concessions in addition to those described above to broker-dealers so that ING mutual funds are made available by those broker-dealers for their customers. The Sub-Adviser of a Fund may contribute to non-cash compensation arrangements.

Not all mutual funds pay the same amount to the broker-dealers who sell their mutual funds. Broker-dealers can receive different payments based on the mutual funds they offer, the companies with whom they are doing business and how much they sell. What these broker-dealers are paid also varies depending on the class of mutual fund you purchase.

The top 25 firms we paid to sell our mutual funds as of the last calendar year are:

Ameriprise Financial Services, Inc.; Charles Schwab & Co., Inc.; Citigroup Global Markets, Inc.; Commonwealth Financial Network; Directed Services LLC; Edward D. Jones & Co., L.P.; Financial Network Investment Corporation; ING Financial Advisers, LLC; ING Financial Partners, Inc.; ING Life Insurance & Annuity; ING Variable Annuity; LPL Financial LLC; Merrill Lynch, Pierce, Fenner & Smith Inc.; Morgan Stanley Smith Barney LLC; National Financial Services Corporation; Oppenheimer & Co., Inc.; Pershing, LLC; PrimeVest Financial Services, Inc.; Raymond James & Associates, Inc.; RBC Capital Markets, LLC; Sharebuilder Securities Corporation; Stifel Nicolas & Co., Inc.; TD Ameritrade, Inc.; UBS Financial Services, LLC; and Wells Fargo Advisors, LLC.

Your registered representative or broker-dealer could have a financial interest in selling you a particular mutual fund, or the mutual funds of a particular company, to increase the compensation they receive. Please make sure you read fully each mutual fund prospectus and discuss any questions you have with your registered representative.
