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 also assume that you invest $10,000 in the Fund for the time periods indicated. It shows 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:

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 Examples, affect the Fund’s performance.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 32% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests in a combination of other ING Funds (“Underlying Funds”) that in turn invest in foreign equity securities of issuers located in a number of different countries, other than the United States. The Fund seeks to diversify its holdings internationally by including Underlying Funds that invest in companies of all market capitalizations, Underlying Funds that invest using a growth or value style and Underlying Funds that invest in companies in both developed countries and countries with emerging securities markets. The Fund may also invest in derivatives, including futures and swaps, other investment companies including exchange traded funds, and other securities to make tactical asset allocations, minimize risk and assist in managing cash. The Fund may hold cash and cash equivalents. The Fund’s current approximate target allocations (expressed as a percentage of its net assets) among the Underlying Funds are set out below. As these are target allocations, the actual allocations of the Fund’s assets may deviate from the percentages shown: international core - 35%; international growth - 17.5%; international value - 17.5%; international small cap - 10%; emerging markets -15%; and international real estate - 5%.

The Fund may be rebalanced periodically to return to the target allocation and inflows and outflows may be managed to attain the target allocation. The target allocation may be changed, at any time, in accordance with the Fund’s asset allocation process.

PRINCIPAL RISKS

You could lose money on an investment in the Fund. Any of the following risks, among others, could affect Fund performance or cause the Fund to lose money or to underperform market averages of other funds.

Asset Allocation  Assets will be allocated among Underlying Funds and markets based on judgments by the Adviser . There is a risk that the Fund may allocate assets to an Underlying Fund or market that underperforms other funds or asset classes.

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.

Currency  To the extent that an Underlying 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.

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 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, and nationalization, expropriation or confiscatory taxation, foreign currency fluctuations, currency blockage, or political changes or diplomatic developments. Foreign investment risks typically are greater in developing and emerging markets than in developed markets.

Growth Investing  Prices of growth stocks typically reflect high expectations for future company growth, and may fall quickly and significantly if investors suspect that actual growth may be less than expected. Growth companies typically lack any dividends that might cushion price declines. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.

Liquidity  If a security is illiquid, an Underlying Fund might be unable to sell the security at a time when the Underlying Fund’s sub-adviser might wish to sell, and the security could have the effect of decreasing the overall level of the 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 an Underlying Fund could realize upon disposition. An Underlying Fund may make investments that become less liquid in response to market developments or adverse

investor perception. An Underlying Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the Underlying Fund.

Market  Stock prices are 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. From time to time, the stock market may not favor the growth- or value-oriented securities in which the Underlying Funds invest. Rather, the market could favor securities to which the Underlying Funds are not exposed or may not favor equities at all.

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 stock of mid- and small-sized companies causing the Underlying Funds that invest 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 stock as compared with larger companies. As a result, stock of mid- and small-capitalization companies may decline significantly in market downturns.

Other Investment Companies  The main risk of investing in other investment companies, including exchange-traded funds, is the risk that the value of the underlying securities 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 that other investment company (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.

Real Estate and Real Estate Investment Trusts (“REITs”)  Investing in real estate companies and REITs may subject an Underlying Fund to risks similar to those associated with the direct ownership of real estate including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, interest rates, zoning laws, regulatory limitations on rents, property taxes and operating expenses, in addition to terrorist attacks, war or other acts that destroy real property.

Value Investing  Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in interest rates, corporate earnings and industrial production.

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

The following information is intended to help you understand the risks of investing in the Fund. The following bar chart and table show the changes in the Fund’s performance from year to year, and the table compares the Fund’s performance to the performance of a broad-based securities market index/indices for the same period. The Fund’s performance information reflects applicable fee waivers and/or expense limitations in effect during the period presented. Absent such fee waivers/expense limitations, if any, performance would have been lower. The bar chart shows the performance of the Fund’s Class A shares, but does not reflect the impact of sales charges. If it did, returns would be lower than those shown. Other class shares performance would be higher than Class A performance because of the higher expenses paid by Class A shares. The Fund’s past performance (before and after taxes) is no guarantee of future results. For the most recent performance figures, go to www.INGFunds.com/literature or call 1-800-992-0180.

After tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts. In some cases the after-tax returns may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are shown for Class A shares only. After-tax returns for other classes will vary.
