("Prospectus")

On March 29, 2013, shareholders of the Fund were sent a proxy statement, which among other things, asked shareholders to approve a new investment advisory fee structure (the "Amended Fee Structure"), which would modify the advisory fees payable to ING Investments, LLC, the Fund's investment adviser, ("Adviser"). Under the Amended Fee Structure, the Fund will pay an advisory fee equal to 0.08% of the Fund's average daily net assets invested in underlying funds in the ING Fund Complex ("Underlying Funds"), and 0.30% of the Fund's average daily net assets invested in direct investments, which include, but are not limited to a security issued by an investment company that is not a part of the ING Fund Complex, including exchange-traded funds, a security issued by a non-mutual fund issuer, such as an operating company, and derivative instruments other than call options written by the Fund's sub-adviser ("Direct Investments"). On June 12, 2013, the Fund's shareholders approved the Amended Fee Structure which became effective on June 12, 2013.

Effective immediately, the Fund's Prospectus is hereby revised as follows:

1.             The table and accompanying footnotes in the section entitled "Fees and Expenses of the Fund — Annual Operating Expenses" of the Fund's Prospectus are hereby deleted and replaced with the following:

(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.

(3)   Effective June 12, 2013, the Fund's Management Fee structure was changed to a "bifurcated fee" structure as follows: an annual rate of 0.08% of the Fund's average daily net assets invested in Underlying Funds within the ING Fund Complex; and 0.30% of the Fund's average daily net assets invested in direct investments, which include, but are not limited to, a security issued by an investment company that is not part of the ING Fund Complex, including exchange-traded funds, a security issued by a non-mutual fund issuer, such as an operating company, and derivative instruments other than call options written by the Fund's sub-adviser. The Management Fees reflected in the table are calculated based on an estimated investment of 20% of the Fund's assets in direct investments.

(4)   Total Annual Fund Operating Expenses may be higher than the Fund's ratio of expenses to average net assets shown in the Financial Highlights, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

(5)   The adviser is contractually obligated to limit expenses to 1.30%, 2.05%, 1.05%, 1.55%, and 1.05% for Class A, Class C, Class I, Class R, and Class W shares, respectively, through at least March 1, 2018; the obligation does not extend to interest, taxes, brokerage commissions, and extraordinary expenses. The obligation will automatically renew for one-year terms unless: (i) the adviser provides 90 days written notice of its termination; and (ii) such termination is approved by the Board of Directors; or (iii) the management agreement has been terminated. The obligation is subject to possible recoupment by the adviser within three years.

(3)   Effective June 12, 2013, the Fund's Management Fee structure was changed to a "bifurcated fee" structure as follows: an annual rate of 0.08% of the Fund's average daily net assets invested in Underlying Funds within the ING Fund Complex; and 0.30% of the Fund's average daily net assets invested in direct investments, which include, but are not limited to, a security issued by an investment company that is not part of the ING Fund Complex, including exchange-traded funds, a security issued by a non-mutual fund issuer, such as an operating company, and derivative instruments other than call options written by the Fund's sub-adviser. The Management Fees reflected in the table are calculated based on an estimated investment of 20% of the Fund's assets in direct investments.

(4)   Total Annual Fund Operating Expenses may be higher than the Fund's ratio of expenses to average net assets shown in the Financial Highlights, which reflects the operating expenses of the Fund and does not include Acquired Fund Fees and Expenses.

(5)   The adviser is contractually obligated to limit expenses to 1.30%, 2.05%, 1.05%, 1.55%, and 1.05% for Class A, Class C, Class I, Class R, and Class W shares, respectively, through at least March 1, 2018; the obligation does not extend to interest, taxes, brokerage commissions, and extraordinary expenses. The obligation will automatically renew for one-year terms unless: (i) the adviser provides 90 days written notice of its termination; and (ii) such termination is approved by the Board of Directors; or (iii) the management agreement has been terminated. The obligation is subject to possible recoupment by the adviser within three years.

The Examples also assume that your investment had a 5% return each year and that the Fund's operating expenses remain the same.
