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:

The Examples reflect applicable expense limitation agreements and/or waivers in effect, if any, for the one- and three-year periods and the first three years of the five- and ten-year periods.

Portfolio Turnover

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 transaction 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 25% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund invests in a combination of other funds in the same fund complex (“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, value, or blend style; and Underlying Funds that invest in companies in both developed countries and countries with emerging securities markets. The Fund may invest in derivative instruments, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, and to assist in managing cash. The Fund may hold cash and cash equivalents. The Fund's current approximate target allocations (“Target Allocations”) (expressed as a percentage of its net assets) among the Underlying Funds are set out below. As these Target Allocations are as of the date of this Prospectus, the actual allocations of the Fund's assets may deviate from the percentages shown: international core - 40%; international growth - 21%; international value - 24%; international small cap - 5%; and emerging markets - 10%. The Target Allocations are measured with reference to the primary strategies of the Underlying Funds; actual exposure to these asset classes will vary from the Target Allocations if an Underlying Fund is not substantially invested in accordance with its primary strategy.

The Fund may also allocate to international real estate in the future. There can be no assurance that this allocation will occur.

The Fund may be rebalanced periodically to return to the Target Allocations. The Fund's Target Allocations may be changed, at any time, in accordance with the Fund's asset allocation process. The Fund may periodically deviate from the Target Allocations based on an assessment of the current market conditions or other factors. Generally, the deviations fall in the range of +/- 10% relative to the current Target Allocations. The adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Fund, to achieve its investment objective, or to take advantage of particular opportunities.

In addition to investing in the Underlying Funds, the Fund may also invest up to 20% of its total assets in exchange-traded funds to gain exposure to equity securities, or alternative strategies, which may include commodities.

PRINCIPAL RISKS

You could lose money on an investment in the Fund. The value of your investment in the Fund changes with the values of the Underlying Funds and their investments. Any of the following risks, among others, could affect the Fund's or an Underlying Fund's performance or cause the Fund or an Underlying 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 or Sub-Adviser. There is a risk that the Fund may allocate assets to an Underlying Fund or asset class that underperforms other funds or asset classes.

Cash/Cash Equivalents    To the extent the Fund holds cash or cash equivalents, the Fund risks achieving lower returns and potential lost opportunities to participate in market appreciation which could negatively impact the Fund’s performance and ability to achieve its investment objective.

Commodities    The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.

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.

Credit Default Swaps    An Underlying Fund may enter into credit default swaps, either as a buyer or a seller of the swap. As a buyer of the swap, an Underlying Fund pays a fee to protect against the risk that a security held by the Underlying Fund will default. As a seller of the swap, an Underlying Fund receives payment(s) in return for its obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, an Underlying Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Underlying Fund would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, correlation, valuation, liquidity and leveraging risks. Certain standardized swaps are subject to mandatory central clearing.  Central clearing is expected to reduce counterparty credit risk and increase liquidity, but central clearing does not make swap transactions risk free.

Currency    To the extent that an Underlying 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 or an Underlying Fund and reduce its returns. Derivatives may not perform as expected, so the Fund or an Underlying Fund may not realize the intended benefits. When used for hedging, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. In addition, given their complexity, derivatives expose the Fund or an Underlying Fund to the risk of improper valuation.

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; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; or political changes or diplomatic developments. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.

Liquidity    If a security is illiquid, an Underlying Fund might be unable to sell the security at a time when the manager might wish to sell, and the security could have the effect of decreasing the overall level of the Fund's or an 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 an Underlying 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. Stock markets tend 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. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to Underlying Funds costs and impair the ability of the Underlying Funds to achieve its investment objectives.

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 an Underlying 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 or an Underlying 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 and a proportionate share of the expenses of each Underlying Fund.

Real Estate Companies 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.

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.voyainvestments.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] Effective October 1, 2013, the Fund's Management Fee structure was changed to a "bifurcated fee" structure as follows: an annual rate of 0.00% of the Fund's average daily net assets invested in Underlying Funds within the Voya family of 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 part of the Voya family of funds, including exchange-traded funds, a security issued by a non-mutual fund issuer, such as an operating company, and derivative instruments.

[2] 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.
