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:

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.

During the most recent fiscal year, the Fund’s portfolio turnover rate was 44% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings for investment purposes) in a portfolio of equity securities of companies that are principally engaged in the real estate industry. The Fund will provide shareholders with at least 60 days’ prior notice of any change in this investment policy. At least 65% of the Fund’s assets will normally be invested in companies located in a number of different countries other than the United States. These companies may have investments that provide exposure to the U.S. real estate industry. The sub-adviser (“Sub-Adviser”) defines a real estate company as a company that: (i) derives at least 50% of its total revenue or earnings from owning, operating, developing, constructing, financing, managing and/or selling commercial, industrial, or residential real estate; or (ii) has at least 50% of its assets invested in real estate. As a general matter, the Fund expects these investments to be in common stocks of companies of any market capitalization, including real estate investment trusts. The Fund may invest in companies located in countries with emerging securities markets. The Fund may also invest in convertible securities, initial public offerings, and Rule 144A securities. 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 uses a multi-step investment process for constructing the Fund’s investment portfolio that combines top-down region and sector allocation with bottom-up individual stock selection.

First, the Sub-Adviser selects sectors and geographic regions in which to invest and determines the degree of representation of such sectors and regions through a systematic evaluation of public and private property market trends and conditions.

Second, the Sub-Adviser uses an in-house valuation process to identify investments with superior current income and growth potential relative to their peers. This in-house valuation process examines several factors including: value and property; capital structure; and management and strategy.

The Fund is non-diversified, which means it may invest a significant portion of its assets in a single issuer.

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.

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.

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.

Concentration   As a result of the Fund “concentrating,” as that term is defined in the 1940 Act, its assets in the securities of a particular industry or group of industries or single country or region, the Fund may be subject to greater market fluctuations than a fund that has securities representing a broader range of investment alternatives. If securities in which the Fund concentrates fall out of favor, the Fund could underperform funds that have greater diversification.

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.
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 (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.

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.

Initial Public Offerings   Initial Public Offerings (“IPOs”) and companies that have recently gone public have the potential to produce substantial gains for the Fund. However, there is no assurance that the Fund will have access to profitable IPOs or that IPOs in which the Fund invests will rise in value. Furthermore, the value of securities of newly public companies may decline in value shortly after the IPO. When the Fund’s asset base is small, the impact of such investments on the Fund’s return will be magnified. If the Fund’s assets grow, it is likely that the effect of the Fund’s investment in IPOs on the Fund’s return will decline.

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.

Issuer Non-Diversification   The Fund is classified as a “non-diversified” investment company and, therefore, is subject to the risks of focusing investments in a small number of issuers, industries or foreign currencies, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be.

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.

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 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.

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.

PERFORMANCE INFORMATION

The following information is intended to help you understand the risks of investing in the Fund. The following bar chart shows 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. Sales charges are not reflected in the bar chart. If they were, returns would be less than those shown. However, the table includes all applicable fees and sales charges. Other class shares’ performance would be higher or lower than Class A shares’ performance because of the higher or lower 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.

[1] A contingent deferred sales charge of 1.00% is assessed on certain redemptions of Class A shares made within 18 months after purchase where no initial sales charge was paid at the time of purchase as part of an investment of $1 million or more.

[1] The adviser and sub-adviser are contractually obligated to limit expenses to 1.50%, 2.25%, 2.25%, 1.25%, and 1.25% for Class A, Class B, Class C, Class I, and Class W shares, respectively, through March 1, 2014. 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 with respect to the sub-adviser, upon termination of the sub-advisory agreement, and is subject to possible recoupment by the adviser and sub-adviser within three years. In addition, effective January 1, 2013, the adviser and sub-adviser are contractually obligated to further limit expenses whereby the sub-adviser will pay the incremental costs necessary to further limit expenses to 1.45%, 2.20%, 2.20%, 1.20%, and 1.20% for Class A, Class B, Class C, Class I, and Class W shares, respectively, through December 31, 2013. There is no guarantee that this obligation will continue after December 31, 2013 and the obligation will continue only if the adviser and sub-adviser elect to renew it. Any fees waived pursuant to this obligation shall not be eligible for recoupment. These obligations do not extend to interest, taxes, brokerage commissions, extraordinary expenses, and Acquired Fund Fees and Expenses.
