Voya Investments, LLC (the Investment Adviser) is contractually obligated to limit expenses to 0.60% and 0.85% for Class I and Class S shares, respectively, through May 1, 2024. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. This limitation is subject to possible recoupment by the Investment Adviser within 36 months of the waiver or reimbursement. The amount of the recoupment is limited to the lesser of the amounts that would be recoupable under: (i) the expense limitation in effect at the time of the waiver or reimbursement; or (ii) the expense limitation in effect at the time of recoupment. Termination or modification of this obligation requires approval by the Portfolio’s Board of Directors (the Board).
Expense Example
This Example is intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract or Qualified Plan. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment had a 5% return each year and that the Portfolio'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 Portfolio 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. These costs, which are not reflected in Annual Portfolio Operating Expenses or in the Expense Example, affect the Portfolio's performance.
During the most recent fiscal year, the Portfolio's portfolio turnover rate was 57% of the average value of its portfolio.
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in securities of small-capitalization companies included in the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy.
The Index is a stock market index comprised of common stocks of 600 small-capitalization companies traded in the United States and selected by S&P Global Ratings. For this Portfolio, the sub-adviser (the Sub-Adviser) defines small-capitalization companies as companies that are included in the Index at the time of purchase. The market capitalization of companies within the Index will change with market conditions. The market capitalization of companies in the Index as of December 31, 2022 ranged from $203.1 million to $6.3 billion.
The Portfolio may invest in derivative instruments including, but not limited to, index futures. The Portfolio typically uses derivatives as a substitute for purchasing securities included in the Index or for the purpose of maintaining equity market exposure on its cash balance.
The Portfolio may also invest in real estate-related securities, including real estate investment trusts (REITs).
The Portfolio may invest in other investment companies, including exchange-traded funds (ETFs), to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder.
In managing the Portfolio, the Sub-Adviser attempts to achieve the Portfolio's objective by overweighting those stocks that the Sub-Adviser believes will outperform the Index, and underweighting (or avoiding altogether) those stocks in the Index that the Sub-Adviser believes will underperform the Index. In determining stock weightings, the Sub-Adviser uses both internally developed quantitative computer models and fundamental stock research to evaluate various criteria, such as the financial strength of each issuer and its potential for strong, sustained earnings growth. Although the Portfolio will not hold all of the stocks in the Index, the Sub-Adviser expects that there will be a close correlation between the performance of the Portfolio and that of the Index in both rising and falling markets as the Portfolio is designed to have risk characteristics (e.g., beta, size, volatility) which approximate those of the Index.
In evaluating investments for the Portfolio, the Sub-Adviser, through its quantitative methods and models, takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of a company. Among the factors considered, the Sub-Adviser expects that its quantitative methods and models will typically take into account environmental, social, and governance (ESG) factors. In considering ESG factors, the Sub-Adviser’s quantitative methods and models will rely primarily on factors identified through the Sub-Adviser’s proprietary empirical research and on third-party evaluations of a company’s ESG standing. ESG factors will be only one of many considerations in the evaluation of any potential investment; the extent to which ESG factors will affect the Sub-Adviser’s decision to invest in a company, if at all, will depend on the operation of the Sub-Adviser’s quantitative processes and the judgment of the Sub-Adviser.
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 Portfolio may lend portfolio securities on a short-term or long-term basis, up to 33 13% of its total assets.
Principal Risks
You could lose money on an investment in the Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.
Summary Prospectus 
2 of 6
Voya Index Plus SmallCap Portfolio

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 the company’s goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying asset, reference rate, or index credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Portfolio. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Portfolio and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Portfolio 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 asset, reference rate, or index 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.
Environmental, Social, and Governance (Quantitative): The Sub-Adviser’s consideration of ESG factors in selecting investments for the Portfolio depends on the operation of quantitative methods and models whose design reflects qualitative and subjective judgments of the Sub-Adviser, including reliance on, or incorporation of, data in respect of ESG factors that may rely on third party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Portfolio’s assets that will be invested in companies that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may not invest in companies that compare favorably to other companies on the basis of ESG factors. It is possible that the Portfolio will have less exposure to certain companies due to the Sub-Adviser’s assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.
Investment Model: The Sub-Adviser’s proprietary model may not adequately take into account existing or unforeseen market factors or the interplay between such factors, and there is no guarantee that the use of the investment model will result in effective investment decisions for the Portfolio. Portfolios that are actively managed, in whole or in part, according to a quantitative investment model can perform differently from the market, 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.
Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio’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 Portfolio to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Portfolio, which could cause the Portfolio to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress.
Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of fixed-income instruments. Additionally, legislative, regulatory, or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the Portfolio to achieve its investment objectives.
Market Disruption and Geopolitical: The Portfolio is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S., and global economies and markets, generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Portfolio’s investments, including beyond the Portfolio’s direct exposure to Russian issuers or nearby geographic regions. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and could be substantial. In March 2023, a number of U.S. domestic banks and foreign (non-U.S.)
Summary Prospectus

Voya Index Plus SmallCap Portfolio

banks experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Portfolio’s investments. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.
Other Investment Companies: The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company’s underlying investments 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 Portfolio’s expenses. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF’s shares, which could cause a material decline in the ETF’s net asset value.
Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject the Portfolio 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, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT’s sponsor. The Portfolio 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 Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio 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 Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio’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 small-capitalization companies are subject to liquidity risk as they are often traded over-the-counter and may not be traded in volumes typically seen on national securities exchanges.
An investment in the Portfolio 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 Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index/indices with investment characteristics similar to those of the Portfolio for the same period. The Portfolio'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 Portfolio's Class S shares. Performance for other share classes would differ to the extent they have differences in their fees and expenses.
Performance shown in the bar chart and in the Average Annual Total Returns table does not include insurance-related charges imposed under a Variable Contract or expenses related to a Qualified Plan. If these charges or expenses were included, performance would be lower. Thus, you should not compare the Portfolio's performance directly with the performance information of other investment products without taking into account all insurance-related charges and expenses payable under your Variable Contract or Qualified Plan. The Portfolio's past performance is no guarantee of future results.

Purchase and Sale of Portfolio Shares
Shares of the Portfolio are not offered directly to the public. Purchase and sale of shares may be made only by separate accounts of insurance companies serving as investment options under Variable Contracts or by Qualified Plans, custodian accounts, and certain investment advisers and their affiliates, other investment companies, or permitted investors. Please refer to the prospectus for the appropriate insurance company separate account, investment company, or your plan documents for information on how to direct investments in, or sale from, an investment option corresponding to the Portfolio and any fees that may apply. Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on the Portfolio's behalf.
Tax Information
Distributions made by the Portfolio to a Variable Contract or Qualified Plan, and exchanges and redemptions of Portfolio shares made by a Variable Contract or Qualified Plan, ordinarily do not cause the corresponding contract holder or plan participant to recognize income or gain for federal income tax purposes. See the contract prospectus or the governing documents of your Qualified Plan for information regarding the federal income tax treatment of the distributions to your Variable Contract or Qualified Plan and the holders of the contracts or plan participants.
Payments to Broker-Dealers and Other Financial Intermediaries
If you invest in the Portfolio through a Variable Contract issued by an insurance company or through a Qualified Plan that, in turn, was purchased or serviced through an insurance company, broker-dealer or other financial intermediary, the Portfolio and its Investment Adviser or distributor or their affiliates may: (1) make payments to the insurance company issuer of the Variable Contract or to the company servicing the Qualified Plan; and (2) make payments to the insurance company, broker-dealer or other financial intermediary. These payments may create a conflict of interest by: (1) influencing the insurance company or the company servicing the Qualified Plan to make the Portfolio available as an investment option for the Variable Contract
