Expense Example

The Example is intended to help you compare the cost of investing in shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example shows costs if you sold (redeemed) your shares at the end of the period or continued to hold them. The Example also assumes that your investment had a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

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 Example, affect the Fund's performance.

During the most recent fiscal year, the Fund's portfolio turnover rate was 57% 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 securities of small market capitalization companies. The Fund will provide shareholders with at least 60 days' prior notice of any change in this investment policy. The Fund currently considers small-capitalization companies to be those companies with market capitalizations that fall within the range of companies in the S&P Developed ex-U.S. Small Cap Index at the time of purchase. Capitalization of companies in the S&P Developed ex-U.S. Small Cap Index will change with market conditions. The market capitalization of companies in the S&P Developed ex-U.S. Small Cap Index as of December 31, 2019, ranged from $28.4 million to $19.4 billion. At least 65% of the Fund's assets will normally be invested in companies located outside the United States, including companies located in countries with emerging securities markets. The Fund may invest up to 35% of its assets in U.S. issuers. The Fund may hold both growth and value stocks and at times may favor one over the other based on available opportunities.

The Fund invests primarily in common stocks or securities convertible into common stocks of international issuers, but may invest from time to time in such instruments as forward foreign currency exchange contracts, futures contracts, rights, and depositary receipts. The Fund may invest in forward foreign currency exchange contracts or futures contracts to hedge currency and for implementation of a currency model within the portfolio. The Fund may invest in futures contracts to allow market exposure in a cost efficient way, maintain exposure to an asset class in the case of large cash flows, and to have access to a particular market in which the Fund wishes to invest.

The Fund may invest in real estate-related securities including real estate investment trusts.

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 applicable exemptive orders thereunder (“1940 Act”).

Voya Investments, LLC (the “Investment Adviser”) allocates the Fund’s assets to different sub-advisers. The Investment Adviser may, from time to time, directly manage a portion of the Fund’s assets to seek to manage the Fund’s overall risk exposure to achieve the Fund’s desired risk/return profile and to effect the Fund’s investment strategies. The Investment Adviser may invest in futures and exchange-traded funds to implement its investment process.

Acadian Asset Management LLC (“Acadian”) and Victory Capital Management Inc. (“Victory Capital”) (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. The Investment Adviser will determine the amount of Fund assets allocated to each Sub-Adviser.

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 30% of its total assets.

Acadian Asset Management LLC

Acadian employs a quantitative investment process which is driven by proprietary valuation models that examine stocks simultaneously from a bottom-up perspective to attempt to predict how each stock will perform relative to its region-industry intersection, and from a top-down perspective to attempt to predict how each stock’s country, industry group, and country intersection will perform relative to their market peers.

Victory Capital Management Inc.

Victory Capital employs a bottom-up investment approach that emphasizes individual stock selection. The investment process uses a combination of quantitative and traditional qualitative, fundamental analysis to identify stocks with low relative price multiples and positive trends in earnings forecasts. The stock selection process is designed to produce a diversified portfolio that, relative to the S&P Developed ex-U.S. Small Cap Index, tends to have a below-average price-to-earnings ratio and an above-average earnings growth trend.

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 company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock 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 instruments, 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: The price of a bond or other debt instrument is likely to 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 its financial obligations altogether.

Currency: To the extent that the Fund invests directly or indirectly 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 by the Fund through foreign currency exchange transactions.

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 market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Fund. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Fund and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Fund may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Fund to the risk of improper valuation.

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, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. 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.

Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.

Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market 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 paid by the securities is a floating rate, which generally will decrease when the market rate of interest to which the inverse security is indexed increases and will increase when the market rate of interest to which the inverse security is indexed decreases. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Fund’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Fund invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Fund to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in fixed-income markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in the fixed-income markets. Further, recent and potential future changes in government policy may affect interest rates.

Investment Model: A manager’s proprietary model may not adequately allow for existing or unforeseen market factors or the interplay between such factors. Funds that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market as a whole based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors’ historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance. There is no guarantee that the use of these investment models will result in effective investment decisions for the Fund.

Investing through Stock Connect: Shares in mainland China-based companies that trade on Chinese stock exchanges such as the Shanghai Stock Exchange and the Shenzhen Stock Exchange (“China A-Shares”) may be purchased directly or indirectly through the Shanghai-Hong Kong Stock Connect (“Stock Connect”), a mutual market access program designed to, among other things, enable foreign investment in the People’s Republic of China (“PRC”) via brokers in Hong Kong. There are significant risks inherent in investing in China A-Shares through Stock Connect. The underdeveloped state of PRC’s investment and banking systems subjects the settlement, clearing, and registration of China A-Shares transactions to heightened risks. Stock Connect can only operate when both PRC and Hong Kong markets are open for trading and when banking services are available in both markets on the corresponding settlement days. As such, if either or both markets are closed on a U.S. trading day, the Fund may not be able to dispose of its China A-Shares in a timely manner, which could adversely affect the Fund’s performance.

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, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Fund to the risk that the price at which it sells illiquid securities will be less than the price at which they were valued when held by the Fund. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. 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 or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, 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. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Fund to achieve its investment objectives.

Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. 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. The investment policies of the other investment companies may not be the same as those of the Fund; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Fund is typically subject.

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, market 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. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Fund will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Securities Lending: Securities lending involves two primary risks: “investment risk” and “borrower default risk.” When lending securities, the Fund will receive cash or U.S. government securities as collateral. 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. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Fund to be more volatile. The use of leverage may increase expenses and increase the impact of the Fund’s other risks.

Small-Capitalization Company: Investments in small-capitalization companies may involve greater risk than is customarily associated with larger, more established companies due to the greater business risks of a limited operating history, small size, limited markets and financial resources, narrow product lines, less management depth and more reliance on key personnel. The securities of smaller companies are subject to liquidity risk as they are often traded over-the-counter and may not be traded in volume typical on a national securities exchange.

Value Investing: Securities that appear to be undervalued may never appreciate to the extent expected. Further, because the prices of value-oriented securities tend to correlate more closely with economic cycles than growth-oriented securities, they generally are more sensitive to changing economic conditions, such as changes in market interest rates, corporate earnings and industrial production. The manager may be wrong in its assessment of a company’s value and the securities the Fund holds may not reach their full values. A particular risk of the Fund’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Fund’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly.

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. Performance for other share classes would differ to the extent they have differences in their fees and expenses.

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 advantaged arrangements such as 401(k) plans or individual retirement accounts (“IRAs”). 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] Expense information has been restated to reflect current contractual rates.

[2] The adviser is contractually obligated to limit expenses to 1.95%, 2.60%, 1.40%, and 1.60% for Class A, Class C, Class I, and Class W shares, respectively, through March 1, 2021. This limitation is subject to possible recoupment by the adviser within 36 months of the waiver or reimbursement. In addition, the adviser is contractually obligated to further limit expenses to 1.53%, 2.28%, 1.20%, and 1.28% for Class A, Class C, Class I, and Class W shares, respectively, through March 1, 2021. These limitations do not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. Termination or modification of these obligations requires approval by the Fund's board.
