Expense Examples $

The Examples are intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Examples assume that you invest $10,000 in the Fund for the time periods indicated. The Examples show costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Examples also assume that your investment had a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Class	Share Status				1 Yr	3 Yrs
A	Sold or Held	$			374	826
C	Sold	$			303	817
	Held	$			203	817
I	Sold or Held	$			97	488
W	Sold or Held	$			102	514

The Examples reflect applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the three-year period.

Portfolio Turnover % of average value of portfolio

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transactions costs

and may mean higher taxes if you are investing in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Expense Examples, affect the Fund’s performance.

Since the Fund had not commenced operations as of the date of this Prospectus, there is no annual portfolio turnover rate information included.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in debt instruments of, or derivatives having economic characteristics similar to the debt instruments of, issuers in emerging market countries. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy.

The Fund may invest in a range of fixed-income and floating rate debt instruments of issuers in emerging markets countries (collectively, “EMD Securities”), including sovereign and corporate debt, through direct investment as well as investment in a combination of other ING Funds (“Underlying Funds”). As of the date of this prospectus, the Fund’s exposure to EMD Securities is achieved primarily through investment in Underlying Funds.

EMD Securities may be denominated in local currencies ( i.e ., denominated in the currency of an emerging markets country), or hard currencies ( i.e ., U.S. Dollars or Euros). Hard currencies are currencies in which investors have confidence and are typically currencies of economically and politically stable industrialized nations.

The Fund’s current approximate target allocations (“Target Allocations”) (expressed as a percentage of its net assets) among the Fund’s asset classes are: sovereign debt securities denominated in hard currencies - 40%; debt securities (including sovereign and corporate debt instruments) denominated in local currencies - 40%; and corporate debt securities denominated in hard currencies - 20%. As these Target Allocations are as of the date of this Prospectus, the actual allocations of the Fund’s assets may deviate from the percentages shown.

The Fund can deviate from the Target Allocations based on an assessment of the current market conditions or other factors. Generally, the deviations fall in the range of +/-20% relative to the current Target Allocations. The Fund’s sub-adviser (“Sub-Adviser”) may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Fund, achieve its investment objective or to take advantage of particular opportunities.

Emerging market countries include most countries in the world except Australia, Austria, Belgium, Canada, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Japan, Malta, The Netherlands, New Zealand, Norway, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, the United Kingdom, and the United States. An emerging market issuer is one: (i) that is organized under the laws of, or has a principal place of business in an emerging market country; (ii) where the principal securities market is in an emerging market country; (iii) that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in emerging market countries; or (iv) at least 50% of the assets of which are located in emerging market countries.

The Fund may invest in obligations of any credit quality and may invest without limit in below investment-grade debt securities (commonly known as “junk bonds”). Fixed-income instruments in which the Fund may also invest include bonds, debt securities and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. Debt securities may include, without limitation, bonds, debentures, notes, convertible securities, commercial paper, loans and related assignments and participations, corporate debt, asset-backed securities, bank certificates of deposit, fixed time deposits, bankers’ acceptances and money market instruments, including money market funds denominated in U.S. dollars or other currencies.

The Fund may also invest in derivatives, including options, futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and currency forwards, to make tactical asset allocations, seek to minimize risk, and/or assist in managing cash. The Fund may hold cash and cash equivalents.

The Fund may invest in exchange-traded funds, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules, regulations, and exemptive orders thereunder (“1940 Act”).

PRINCIPAL RISKS

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect the Fund’s or an Underlying Fund’s performance or cause the Fund or an Underlying Fund to lose money or to underperform market averages of other funds. The value of your investment in the Fund will also change with the values of the Underlying Funds and their investments.

Asset Allocation   The success of the Fund’s strategy depends on the Adviser’s or Sub-Adviser’s skill in allocating Fund assets between the asset classes and in choosing investments within those categories. There is a risk that the Fund may allocate assets to an asset class that underperforms other asset classes.

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, the Fund or an Underlying 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.

Convertible Securities   Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks

---

associated with debt securities, such as interest rate and credit risk. In addition, because convertible securities react to changes in the value of the stocks into which they convert, they are subject to market risk.

Credit   Prices of bonds and other debt instruments 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 Default Swaps   The Fund or an Underlying Fund may enter into credit default swaps, either as a buyer or a seller of the swap. As a buyer of the swap, the Fund or an Underlying Fund pays a fee to protect against the risk that a security held by the Fund or the Underlying Fund will default. As a seller of the swap, the Fund or an Underlying Fund receives payment(s) in return for its obligation to pay the counterparty the full national value of the security in the event of a default of the security issuer. As a seller of a swap, the Fund or an Underlying Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund or an Underlying Fund would be subject to investment exposure on the notional value of the swap. Credit default swaps are largely unregulated and susceptible to liquidity, credit, and counterparty risks.

Currency   To the extent that the Fund or an Underlying Fund invests directly in foreign (non-U.S.) currencies or in securities denominated in, or that trade in, foreign (non-U.S.) currencies, it is subject to the risk that those (non-U.S.) 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.

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 the Fund or an Underlying Fund and reduce its returns.

Foreign Investments/Developing and Emerging Markets Investing in foreign (non-U.S.) securities may result in the Fund or the Underlying Funds experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due to: smaller markets; differing reporting, accounting, and auditing standards; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Foreign investment risks may be greater in developing and emerging markets than in developed markets.

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.

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 instruments, 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 instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. In the case of inverse securities, the interest rate generally will decrease when the market rate of interest to which the inverse security is indexed decreases.

Leverage   Certain transactions and investment strategies may give rise to leverage. Such transactions and investment strategies, include, but are not limited to: borrowing, dollar rolls, reverse repurchase agreements, loans of portfolio securities and the use of when-issued, delayed-delivery or forward-commitment transactions. The use of certain derivatives may also increase leveraging risk. The use of leverage may increase the Fund’s expenses and increase the impact of the Fund’s other risks.

Liquidity   If a security is illiquid, the Fund or an Underlying Fund might be unable to sell the security at a time when the manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund or an Underlying 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 the Fund or an Underlying Fund could realize upon disposition. The Fund or an Underlying Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund or an Underlying Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Fund or an Underlying 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 the Fund or an Underlying Fund that invests in these companies to increase in value more rapidly than a fund that invests in larger, fully-valued companies. Investing

in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, and a more limited trading market for their stocks as compared with larger companies. As a result, stocks of mid- and small-capitalization companies may decline significantly in market downturns.

Mortgage- and/or Asset-Backed Securities   Defaults on or the low credit quality or liquidity of the underlying assets of the asset-backed (including mortgage-backed) securities held by the Fund or an Underlying 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.

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

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 the Fund or an Underlying Fund later than expected which may decrease the value of the obligation and prevent the Fund or an Underlying Fund from investing expected repayment proceeds in securities paying yields higher than the yields paid by the securities that were expected to be repaid.

Sovereign Debt   These securities are issued or guaranteed by foreign government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt. Some of these reasons may include cash flow problems, insufficient foreign currency reserves, political considerations, the relative size of its debt position to its economy or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting sovereign debts that a government does not pay or bankruptcy proceeding by which all or part of sovereign debt that a government entity has not repaid may be collected.

An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

PERFORMANCE INFORMATION

Because the Fund did not have a full calendar year of operations as of December 31, 2012, there is no annual performance information included.
