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 February 28, 2013, as supplemented, and the audited financial statements on pages 20-48 of the Fund’s shareholder report dated October 31, 2012 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.

Class	Maximum sales charge (load) as a % of offering price	Maximum deferred sales charge as a % of purchase or sales price, whichever is less
I	None	None
W	None	None

1	Based on Class I shares’ expenses.
2	Total Annual Fund Operating Expenses may be higher than the Fund’s ratio of expenses to average net assets shown in the Fund’s Financial Highlights, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.
3	The adviser is contractually obligated to limit expenses to 0.95% and 0.95% for Class I shares and Class W shares, respectively, through March 1, 2014; the obligation does not extend to interest, taxes, brokerage commissions, extraordinary expenses, and Acquired Fund Fees and Expenses. The obligation will automatically renew for one-year terms unless it is terminated by the Fund or the adviser upon written notice within 90 days of the end of the current term or upon termination of the advisory agreement and is subject to possible recoupment by the adviser within three years.

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	5 Yrs	10 Yrs
I	Sold or Held	$	98	317	553	1,232
W	Sold or Held	$	98	317	553	1,232

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-, five-, and ten-year periods.

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 Example, affect the Fund’s performance.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 71% of the average value of its portfolio.

At the close of business on November 22, 2013, Thornburg Investment Management, Inc. (“Thornburg”) was terminated as a sub-adviser to the Fund. On or about November 25, 2013, Wellington Management Company, LLT became the sole sub-adviser managing the Fund’s assets. During the period from the close of business November 8, 2013 through the close of business on November 22, 2013, the Fund was in a transition period during which time all or most of the assets managed by Thornburg were sold. These transactions resulted in significant

Under normal market conditions, the Fund invests at least 65% of its total assets in equity securities of companies located in a number of different countries other than the United States. The Fund may invest in countries with emerging securities markets. The Fund’s emerging markets exposure will generally not be greater than 10% above the emerging markets exposure of the MSCI All Country World ex U.S. Index. Emerging markets will be defined as countries that are included in the MSCI Emerging Markets Index^SM . The Fund may also invest in depositary receipts of foreign issuers. The Fund may invest up to 15% of its assets in real estate investment trusts.

The Fund may use derivatives, including futures, options, swaps, and forward contracts, typically for hedging purposes to reduce risk, such as interest rate risk, currency risk, and price risk.

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”).

The sub-adviser (“Sub-Adviser”) conducts fundamental research on individual companies to identify securities for purchase or sale. Fundamental analysis of a company involves the assessment of such factors as its business environment, management quality, balance sheet, income statement, anticipated earnings, revenues and dividends, and other related measures and indicators of value. The Sub-Adviser seeks to invest in companies with underappreciated assets, improving and/or sustainable return on capital, and/or stocks that it believes are mispriced by the market due to short-term issues. This proprietary research takes into account each company’s long-term history as well as the Sub-Adviser’s analysts’ forward-looking estimates, and allows for a comparison of the intrinsic value of stocks on a global basis focusing on return on invested capital in conjunction with other valuation metrics. Portfolio construction is driven primarily by bottom-up stock selection, with region, country, and sector weightings being secondary factors.

The 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 total assets.

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 stock could become worthless.

Currency To the extent that the 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 foreign (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 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; 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.

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 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. From time to time, the stock market may not favor the value-oriented securities in which the Fund invests. Rather, the market could favor growth-oriented securities 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

ING International Core Fund

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 those other investment companies (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.

The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows the Fund’s performance for the first full calendar year of operations 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 I 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.

Because Class W shares of the Fund did not have a full calendar year of operations as of December 31, 2012, no performance information for Class W shares is provided below.
