Before you invest, you may want to review the Fund’s Prospectus, which contains more information about the Fund and its risks. For free paper or electronic copies of the Prospectus and other Fund information (including the Statement of Additional Information and most recent financial report to shareholders), go to www.INGFunds.com/literature; email a request to Literature_request@INGFunds.com; call 1-800-992-0180; or ask your salesperson, financial intermediary, or retirement plan administrator. The Fund’s Prospectus and Statement of Additional Information, each dated September 30, 2011, are incorporated into this Summary Prospectus by reference and may be obtained free of charge at the website, phone number, or e-mail address noted above.

These tables describe the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts if you and your family invest, or agree to invest in the future, at least $100,000 in ING Funds. More information about these and other discounts is available from your financial professional and in the discussion in the Sales Charges section of the Prospectus (page 17) or the Statement of Additional Information (page 84).

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:

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.

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.

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of issuers in emerging markets. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy.

Developing or emerging countries include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, the United States, and most of the countries of Western Europe. An emerging market company is one: that is organized under the laws of, or has a principal place of business in an emerging market; where the principal securities market is in an emerging market; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or at least 50% of the assets of which are located in an emerging market. The Fund may invest in companies of any market capitalization.

Equity securities may include common stock, preferred stock, convertible securities, depositary receipts, participatory notes, trust or partnership interests, warrants and rights to buy common stock, and privately placed securities. The Fund may also invest in real estate investment trusts and non-investment grade bonds (high-yield or “junk bonds”).

The Fund may invest in derivatives, including but not limited to, futures, options, swaps, and forwards as a substitute for securities in which the Fund can invest; to hedge various investments; to seek to reduce currency deviations, where practicable, for the purpose of risk management; to seek to increase the Fund’s gains; and for the efficient management of cash flows.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies, and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may, from time to time, hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may invest in other investment companies, including 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”).

Each sub-adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising, among others.

The Fund may lend portfolio securities on a short-term or long-term basis, up to 33¹ /₃ % of its assets.

Delaware Management Company (“Delaware Management”) and J.P. Morgan Investment Management Inc. (“JPMorgan”) (each a “Sub-Adviser” and collectively “Sub-Advisers”) provide the day-to-day management of the Fund. The Sub-Advisers act independently of each other and use their own methodology for selecting investments. ING Investments, LLC, the Fund’s investment adviser, will determine the amount of Fund assets allocated to each Sub-Adviser.

Delaware Management selects growth-oriented and value-oriented investments on the basis of the investment’s discount to its intrinsic value. When selecting growth-oriented securities, Delaware Management typically seeks high growth caused by secular economic factors. These factors may include demographics, economic deregulation, and technological developments. When selecting value-oriented securities, Delaware Management typically seeks lower valuations caused by cyclical economic factors or temporary changes in business operations. Strong management and sustainable business franchise are key considerations in selecting both growth-oriented and value-oriented securities.

In order to compare the value of different stocks, Delaware Management considers whether the future income stream on a stock is expected to increase faster than, slower than, or in line with the level of inflation. Delaware Management then estimates what it thinks the value of the anticipated future income stream would be worth if such income stream were being paid today. Delaware Management believes this gives it an estimate of the stock’s intrinsic value.

Because the Fund invests primarily in emerging countries, there may be less information available for the Delaware Management to use in making this analysis than is available for more developed countries. Currency analysis is an important part of the valuation exercise. Delaware Management attempts to determine whether a particular currency is overvalued or undervalued by comparing the amount of goods and services that a dollar will buy in the United States to the amount of foreign currency required to buy the same amount of goods and services in another country. When the dollar buys less, the foreign currency may be overvalued, and when the dollar buys more, the foreign currency may be undervalued. Relative per capita income levels are also a key factor in this analysis.

JPMorgan emphasizes securities that it believes are ranked as undervalued, while underweighting or avoiding securities that appear overvalued.

In managing its portion of the Fund, JPMorgan adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Fund’s investment universe which JPMorgan uses to select securities. Securities held in the Fund that JPMorgan believes have become overvalued and/or whose factor signals have deteriorated materially may be sold and are generally replaced with more attractive securities on the basis of JPMorgan’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction. JPMorgan utilizes currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

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.

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 stocks 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.

Currency To the extent that the 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 and reduce its returns.

Foreign Investments/Developing and Emerging Markets Investing in foreign (non-U.S.) securities may result in the Fund 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.

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 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.

Investment Model Each Sub-Adviser’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors.

Liquidity If a security is illiquid, the Fund might be unable to sell the security at a time when the 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 the Fund could realize upon disposition. The Fund may make investments that become less liquid in response to market developments or adverse investor perception. The Fund could lose money if it cannot sell a security at the time and price that would be most beneficial to the 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 Fund invests. Rather, the market could favor securities to which the Fund is 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 stocks of mid- and small-sized companies causing the 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

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 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.

Real Estate Companies and Real Estate Investment Trusts (“REITs”) Investing in real estate companies and REITs may subject the 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.

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

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.

Since the Fund had not commenced operations as of the calendar year ended December 31, 2010, there is no annual performance information included.

Shares of the Fund may be purchased or sold on any business day (normally any day when the New York Stock Exchange is open). You can buy or sell shares of the Fund through a broker-dealer or other financial intermediary; by visiting our website at www.INGInvestment.com; by writing to us at ING Funds, 7337 East Doubletree Ranch Road, Suite 100, Scottsdale, Arizona 85258; or by calling us at 1-800-992-0180.

There are no minimums for additional investments except that the Pre-Authorized Investment Plan requires a monthly investment of at least $100.

The Fund intends to make distributions that may be taxable as ordinary income or capital gains.

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Fund and its related companies may pay the intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary’s website for more information.
