Voya Emerging Markets Index Portfolio  
Investment Objective
The Portfolio seeks investment results (before fees and expenses) that correspond to the total return (which includes capital appreciation and income) of an index that measures the investment return of emerging markets securities (“Index”).
Fees and Expenses of the Portfolio
The table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Portfolio’s expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.55 % and 0.80% 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 33% of the average value of its portfolio.

Voya Emerging Markets Index Portfolio
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; depositary receipts representing securities in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all, or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in equity securities and employs a “passive management” approach designed to track the performance of the Index (currently the MSCI Emerging Markets IndexSM ). The securities for the Portfolio are chosen using statistical techniques so as to minimize the anticipated tracking error to the Index. This approach is employed because of the relatively large number of small and/or illiquid stocks in the Index.
The MSCI Emerging Markets IndexSM captures large- and mid- capitalization representation across 24 emerging markets countries and covers approximately 85% of the free float-adjusted market capitalization in each country. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, portions of the Index were focused in the financials sector and the information technology sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position as well as forward foreign currency exchange contracts to hedge currency risk. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
China Investing Risks: The Chinese economy is generally considered an emerging and volatile market. Although China has experienced a relatively stable political environment in recent years, there is no guarantee that such stability will be maintained in the future. Significant portions of the Chinese securities markets may become rapidly illiquid because Chinese issuers have the ability to suspend the trading of their equity securities under certain circumstances, and have shown a willingness to exercise that option in response to market volatility, epidemics, pandemics, adverse economic, market or political events, and other events. Political, regulatory and diplomatic events, such as the U.S.-China “trade war” that intensified in 2018, could have an adverse effect on the Chinese or Hong Kong economies and on related investments. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States signed an Executive Order prohibiting U.S. persons from purchasing or investing in publicly-traded securities of companies identified by the U.S. government as “Communist Chinese military companies.” The list of such companies can change from time to time, and as a result of forced selling or inability to participate in an investment the Investment Adviser/Sub-Adviser otherwise believes is attractive, the Portfolio may incur losses.

•
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 Portfolio may not be able to dispose of its China A-Shares in a timely manner, which could adversely affect the Portfolio’s performance.
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.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
Currency: To the extent that the Portfolio 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 Portfolio 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 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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Financial Services Sector: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.
Voya Emerging Markets Index Portfolio

•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.
Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing , and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the U.S. 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 (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.
Index Strategy for Voya Emerging Markets Index Portfolio: The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate. In addition, compliance with sanctions imposed by the U.S. or other governments against certain Russian issuers whose securities are included in the Portfolio’s index may impair the Portfolio’s ability to purchase, sell, receive, deliver or obtain exposure to those securities, and may interfere with the Portfolio’s ability to track its index.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.
Voya Emerging Markets Index Portfolio

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.
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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 1.00%, 0.50%, 0.75%, and 0.90% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. In addition, the Investment Adviser is contractually obligated to further limit expenses to 0.95%, 0.45%, 0.70%, and 0.85% for the Portfolio’s Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. The limitations do not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. These limitations are 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. The distributor is contractually obligated to waive 0.01% of the distribution fee for Class ADV shares through May 1, 2024. Termination or modification of these obligations 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 two years 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 17% of the average value of its portfolio.

Voya International Index Portfolio
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all, or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index (currently the MSCI EAFE® Index).
The MSCI EAFE® Index captures large- and mid - capitalization representation across 21 developed markets countries around the world, excluding the U.S. and Canada , and covers approximately 85% of the free float-adjusted market capitalization in each country. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, portions of the Index were focused in the financials sector and the industrials sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position as well as forward foreign currency exchange contracts to hedge currency risk. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
Currency: To the extent that the Portfolio 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 Portfolio through foreign currency exchange transactions.
Voya International Index Portfolio

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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Financial Services Sector: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.
•
Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.
Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing , and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the U.S. 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 (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for
Voya International Index Portfolio
10
certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including
Voya International Index Portfolio
11
being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.
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.
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 ADV 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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.93%, 0.43%, and 0.68 for Class ADV, 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. The Investment Adviser is contractually obligated to waive 0.10% of the management fee through May 1, 2024. Termination or modification of these obligations 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 21% 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 equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.

Voya RussellTM Large Cap Growth Index Portfolio
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the especially large-capitalization segment of the U.S. equity universe, represented by stocks in the largest 200 by market capitalization. The Index includes Russell Top 200® Index companies with relatively higher price-to-book ratios, higher Institutional Broker’s Estimate System (I/B/E/S) forecast medium term (2 year) growth, and higher sales per share historical growth (5 years).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 $25.7 billion to $2.1 trillion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, a portion of the Index was concentrated in the information technology sector and a portion of the Index was focused in the consumer discretionary sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
Concentration (Index): To the extent that the Portfolio’s index “ concentrates, ” as that term is defined in the 1940 Act, in the securities of a particular industry or group of industries, the Portfolio may allocate its investments to approximately the same extent as the index. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry or group of industries, and if securities of such industry or group of industries fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that is more broadly invested across industries.
•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.

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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Consumer Sectors: Investments in companies involved in the consumer sectors may be affected by changes in the domestic and international economies, exchange rates, competition, consumers’ disposable income, and consumer preferences.
Growth Investing: Prices of growth -oriented stocks are more sensitive to investor perceptions of the issuer ’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-oriented stocks tend to be more volatile than value-oriented stocks, and may underperform the market as a whole over any given time period.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below
Voya RussellTM Large Cap Growth Index Portfolio
16
zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.

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.
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.
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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.87%, 0.37%, 0.62%, and 0.77% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. 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. In addition, the Investment Adviser is contractually obligated to further limit expenses to 0.86%, 0.36%, 0.61%, and 0.76% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. The 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 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 13% of the average value of its portfolio.

Voya RussellTM Large Cap Index Portfolio
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the largest capitalization segment of the U.S. equity universe. The Index is a subset of the Russell 3000® Index, includes approximately 200 of the largest securities (based on a combination of their market capitalization and current index membership), and represents approximately 68% of the total market capitalization of the Russell 3000® Index. 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 $25.7 billion to $2.1 trillion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, a portion of the Index was concentrated in the information technology sector and a portion of the Index was focused in the health care sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
Concentration (Index): To the extent that the Portfolio’s index “ concentrates, ” as that term is defined in the 1940 Act, in the securities of a particular industry or group of industries, the Portfolio may allocate its investments to approximately the same extent as the index. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry or group of industries, and if securities of such industry or group of industries fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that is more broadly invested across industries.

•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Health Care Sector: Investments in companies involved in the health care sector are strongly affected by worldwide scientific or technological developments. Products sold by companies in the health care sector may rapidly become obsolete and are also often dependent on access to resources and the company’s ability to receive patents from regulatory agencies. Many health care companies also are subject to significant government regulation and may be affected by changes in governmental policies. As a result, investments in health care companies include the risk that the economic prospects, and the share prices, of such companies can fluctuate dramatically.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and
Voya RussellTM Large Cap Index Portfolio
22
related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company
Voya RussellTM Large Cap Index Portfolio
23
may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.
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.
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 ADV 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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Investment Objective
The Portfolio seeks investment results (before fees and expenses) that correspond to the total return (which includes capital appreciation and income) of the Russell Top 200® Value Index (“Index”).
Fees and Expenses of the Portfolio
The table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Portfolio’s expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.93%, 0.43%, and 0.68% for Class ADV, 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. The Investment Adviser is contractually obligated to waive 0.10% of the management fee through May 1, 2024. Termination or modification of these obligations 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 26% 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 equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.
26
Voya RussellTM Large Cap Value Index Portfolio
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the especially large capitalization segment of the U.S. equity universe, represented by stocks in the largest 200 by market capitalization that exhibit value characteristics. The Index includes Russell Top 200® Index companies with relatively lower price-to-book ratios, lower Institutional Broker’s Estimate System (I/B/E/S) forecast medium term (2 year) growth, and lower sales per historical growth (5 years). 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 $25.7 billion to $1.1 trillion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, portions of the Index were focused in the financials sector and the health care sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
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.
Voya RussellTM Large Cap Value Index Portfolio
27
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Financial Services Sector: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.
•
Health Care Sector: Investments in companies involved in the health care sector are strongly affected by worldwide scientific or technological developments. Products sold by companies in the health care sector may rapidly become obsolete and are also often dependent on access to resources and the company’s ability to receive patents from regulatory agencies. Many health care companies also are subject to significant government regulation and may be affected by changes in governmental policies. As a result, investments in health care companies include the risk that the economic prospects, and the share prices, of such companies can fluctuate dramatically.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.

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.
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 Portfolio holds may not reach their full values. Risks associated with value investing include that a security that is perceived by the manager to be undervalued may actually be appropriately priced and, thus, may not appreciate and provide anticipated capital growth. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented securities may underperform other funds that invest more broadly.
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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Investment Objective
The Portfolio seeks investment results (before fees and expenses) that correspond to the total return (which includes capital appreciation and income) of the Russell Midcap® Growth Index (“Index”).
Fees and Expenses of the Portfolio
The table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Portfolio’s expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.43%, 0.68%, and 0.83% for Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. 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. In addition, the Investment Adviser is contractually obligated to further limit expenses to 0.40%, 0.65%, and 0.80% for Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. The limitations do not extend to interest, taxes, investment-related costs, leverage expenses, extraordinary expenses, and Acquired Fund Fees and Expenses. The Investment Adviser is contractually obligated to waive 0.10% of the management fee through May 1, 2024. Termination or modification of these obligations 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 38% of the average value of its portfolio.

Voya RussellTM Mid Cap Growth Index Portfolio
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the mid-capitalization segment of the U.S. equity universe. The Index includes those Russell Midcap® Index companies with relatively higher price-to-book ratios, higher Institutional Broker’s Estimate System (I/B/E/S) forecast medium term (2 year) growth, and higher sales per share historical growth (5 years).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 $735.7 million to $52.8 billion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, a portion of the Index was concentrated in the information technology sector and portions of the Index were focused in the consumer discretionary sector, the health care sector, and the industrials sector.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
Concentration (Index): To the extent that the Portfolio’s index “ concentrates, ” as that term is defined in the 1940 Act, in the securities of a particular industry or group of industries, the Portfolio may allocate its investments to approximately the same extent as the index. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry or group of industries, and if securities of such industry or group of industries fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that is more broadly invested across industries.
Voya RussellTM Mid Cap Growth Index Portfolio
33
•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Consumer Sectors: Investments in companies involved in the consumer sectors may be affected by changes in the domestic and international economies, exchange rates, competition, consumers’ disposable income, and consumer preferences.
•
Health Care Sector: Investments in companies involved in the health care sector are strongly affected by worldwide scientific or technological developments. Products sold by companies in the health care sector may rapidly become obsolete and are also often dependent on access to resources and the company’s ability to receive patents from regulatory agencies. Many health care companies also are subject to significant government regulation and may be affected by changes in governmental policies. As a result, investments in health care companies include the risk that the economic prospects, and the share prices, of such companies can fluctuate dramatically.
•
Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.
Growth Investing: Prices of growth -oriented stocks are more sensitive to investor perceptions of the issuer ’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-oriented stocks tend to be more volatile than value-oriented stocks, and may underperform the market as a whole over any given time period.
Voya RussellTM Mid Cap Growth Index Portfolio
34
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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.) 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
Voya RussellTM Mid Cap Growth Index Portfolio
35
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.
Mid-Capitalization Company: Investments in mid-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, smaller size, limited markets, and financial resources, narrow product lines, less management depth, and more reliance on key personnel. Consequently, the securities of mid-capitalization companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.
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.
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 S2 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

or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Investment Objective
The Portfolio seeks investment results (before fees and expenses) that correspond to the total return (which includes capital appreciation and income) of the Russell Midcap® Index (“Index”).
Fees and Expenses of the Portfolio
The table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the Portfolio. You may pay other fees and expenses such as fees and expenses imposed under your variable annuity contracts or variable life insurance policies (“Variable Contract”) or a qualified pension or retirement plan (“Qualified Plan”), which are not reflected in the tables and examples below. If these fees or expenses were included in the table, the Portfolio’s expenses would be higher. For more information on these charges, please refer to the documents governing your Variable Contract or consult your plan administrator.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.93%, 0.43%, 0.68%, and 0.83% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. 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. In addition, the Investment Adviser is contractually obligated to further limit expenses to 0.90%, 0.40%, 0.65%, and 0.80% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. The 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 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 18% of the average value of its portfolio.

Voya RussellTM Mid Cap Index Portfolio
Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the mid-capitalization segment of the U.S. equity universe. The Index is a subset of the Russell 1000® Index, includes approximately 800 of the smallest securities (based on a combination of their market capitalization and current index membership), and represents approximately 27% of the total market capitalization of the Russell 1000® Index. 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 $653.0 million to $52.8 billion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, portions of the Index were focused in the industrials sector and the information technology sector and a portion of the Index was invested in real estate-related securities, including real estate investment trusts (“REITs”).
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
Voya RussellTM Mid Cap Index Portfolio
40
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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.
•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below
Voya RussellTM Mid Cap Index Portfolio
41
zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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.) 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.
Mid-Capitalization Company: Investments in mid-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, smaller size, limited markets, and financial resources, narrow product lines, less management depth, and more reliance on key personnel. Consequently, the securities of mid-capitalization companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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
Voya RussellTM Mid Cap Index Portfolio
42
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.
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 ADV 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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.95%, 0.45%, 0.70%, and 0.85% for Class ADV, Class I, Class S, and Class S2 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”).

Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in equity securities of companies, which are at the time of purchase, included in the Index; convertible securities that are convertible into stocks included in the Index; other derivatives whose economic returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all or substantially all of its assets in these securities.
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 (the “1940 Act”).
The Portfolio currently invests principally in common stocks and employs a “passive management” approach designed to track the performance of the Index.
The Index measures the performance of the small-capitalization segment of the U.S. equity universe. The Index is a subset of the Russell 3000® Index, includes approximately 2,000 of the smallest securities (based on a combination of their market capitalization and current index membership), and represents approximately 7% of the total market capitalization of the Russell 3000® Index. 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 $6.1 million to $7.9 billion. Because the Portfolio’s assets invested in common stocks will be allocated in approximately the same relative proportion as the Index, the Portfolio may concentrate to approximately the same extent that the Index concentrates in the stock of a particular industry or group of industries. As of February 28, 2023, portions of the Index were focused in the financials sector, the health care sector, and the industrials sector and a portion of the Index was invested in real estate-related securities, including real estate investment trusts (“REITs”).
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
The Portfolio may not always hold all of the same securities as the Index. The Portfolio may also invest in stock index futures as a substitute for the sale or purchase of securities in the Index and to provide equity exposure to the Portfolio's cash position. Although the Portfolio attempts to track, as closely as possible, the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
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.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations .
Voya RussellTM Small Cap Index Portfolio
46
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.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters , affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Financial Services Sector: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.
•
Health Care Sector: Investments in companies involved in the health care sector are strongly affected by worldwide scientific or technological developments. Products sold by companies in the health care sector may rapidly become obsolete and are also often dependent on access to resources and the company’s ability to receive patents from regulatory agencies. Many health care companies also are subject to significant government regulation and may be affected by changes in governmental policies. As a result, investments in health care companies include the risk that the economic prospects, and the share prices, of such companies can fluctuate dramatically.
•
Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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,
Voya RussellTM Small Cap Index Portfolio
47
recent and potential future changes in government policy may affect interest rates. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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.) 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.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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
Voya RussellTM Small Cap Index Portfolio
48
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 ADV 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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

Voya Investments, LLC (the “ Investment Adviser ” ) is contractually obligated to limit expenses to 0.88%, 0.38%, 0.63%, and 0.78% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. 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. In addition, the Investment Adviser is contractually obligated to further limit expenses to 0.86%, 0.36%, 0.61%, and 0.76% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2024. The 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 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 464% 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 investment-grade debt instruments rated at least A by Moody's Investors Service, Inc., at least A by S&P Global Ratings, or are of comparable quality if unrated, which are at the time of purchase, included in the Index; derivatives whose economic
51
Voya U.S. Bond Index Portfolio
returns are, by design, closely equivalent to the returns of the Index or its components; and exchange-traded funds that track the Index. The Portfolio will provide shareholders with at least 60 days' prior notice of any change in this investment policy. Under normal market conditions, the Portfolio invests all, or substantially all, of its assets in these securities. The Portfolio may also invest in To Be Announced (“TBA”) purchase commitments. TBAs shall be deemed included in the Index upon entering into the contract for the TBA if the underlying securities are included in the Index.
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 (the “1940 Act”).
The Portfolio invests principally in bonds and employs a “passive management” approach designed to track the performance of the Index. The Portfolio uses quantitative and qualitative techniques to match the expected return of the Index for changes in spreads and interest rates. As a result of the process, the Portfolio will hold debt instruments in proportions that differ from those represented in the Index.
The Index is a broad-based benchmark that measures the investment grade, U.S. dollar-denominated, fixed-rate taxable bond market. The Index includes U.S. Treasuries, government-related and corporate securities, fixed-rate agency mortgage-backed securities, asset-backed securities, and commercial mortgage-backed securities (agency and non-agency).
The Portfolio uses quantitative techniques to match the expected return of the Index for changes in spreads and interest rates. The process results in a Portfolio that will hold fixed-income instruments in proportions that differ from those represented in the Index. The Portfolio maintains a weighted average effective duration within one year on either side of the duration of the Index, which generally ranges between 3.5 and 6 years. Duration is a commonly used measure of risk in fixed-income instruments as it incorporates multiple features of the fixed-income instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the fixed-income instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the fixed-income instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%.
In seeking to track the performance of the Index, the Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index. As a result, whether at any time the Portfolio will be considered “diversified” or “non-diversified” will depend largely on the make-up of the Index at the time.
Generally, the Portfolio will not hold all of the same fixed-income instruments as the Index. The Portfolio may also invest in futures as a substitute for the sale or purchase of fixed-income instruments in the Index and to provide fixed-income exposure to the Portfolio's cash position. Although the Portfolio attempts to closely track the performance of the Index, the Portfolio does not always perform exactly like the Index. Unlike the Index, the Portfolio has operating expenses and transaction costs and therefore, has a performance disadvantage versus the Index.
The sub-adviser (the “Sub-Adviser”) may sell securities for a variety of reasons, such as to rebalance and reconstitute its investments in connection with such changes in the Index, 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 1∕3% 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.
Credit: The Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived ( whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations . Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.
Voya U.S. Bond Index Portfolio
52
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.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent the Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent the Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between the Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, the Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments ; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income instruments, 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 Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio’s operations and return potential.
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 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.) 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.
Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of , the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of fixed-income instruments.
Non-Diversification (Index): Depending on the composition of the Index, the Portfolio may at any time, with respect to 75% of the Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, the Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. The Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and the Portfolio’s shares may experience significant fluctuations in value.
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.
Prepayment and Extension: Many types of fixed-income instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a fixed-income instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a fixed-income instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a fixed-income instrument will pay back the principal later than expected. This risk is heightened in a rising market interest rate environment. This may negatively affect performance, as the value of the fixed-income instrument decreases when principal payments are made later than expected. Additionally, the Portfolio may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.
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.

U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk.
When-Issued, Delayed Delivery and Forward Commitment Transactions : When - issued , delayed delivery and forward commitment transactions involve the risk that the security the Portfolio buys will lose value prior to its delivery. These transactions 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. There also is the risk that the security will not be issued or that the other party will not meet its obligation. If this occurs, the Portfolio loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.
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 ADV 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 or the Qualified Plan; or (2) by influencing the broker-dealer or other intermediary and your salesperson to recommend the Variable Contract or the pension servicing agent and/or the Portfolio over other options. Ask your salesperson or Qualified Plan administrator or visit your financial intermediary's website for more information.

KEY PORTFOLIO INFORMATION
This Prospectus contains information about each Portfolio and is designed to provide you with important information to help you with your investment decisions. Please read it carefully and keep it for future reference.
Each Portfolio's Statement of Additional Information (the “SAI”) is incorporated by reference into (legally made a part of) this Prospectus. It identifies investment restrictions, more detailed risk descriptions, a description of how the bond rating system works, and other information that may be helpful to you in your decision to invest. You may obtain a copy, without charge, from each Portfolio.
Neither this Prospectus, nor the related SAI, nor other communications to shareholders, such as proxy statements, is intended, or should be read, to be or give rise to an agreement or contract between Voya Variable Portfolios, Inc. (the “Company”), the Board of Directors (the “Board”), or each Portfolio and any investor, or to give rise to any rights to any shareholder or other person other than any rights under federal or state law.
Other Voya mutual funds may also be offered to the public that have similar names, investment objectives, and principal investment strategies as those of a Portfolio. You should be aware that each Portfolio is likely to differ from these other Voya mutual funds in size and cash flow pattern, as well as other factors. Accordingly, the performance of each Portfolio can be expected to vary from those of other Voya mutual funds.
Other mutual funds and/or funds-of-funds may invest in a Portfolio. So long as a Portfolio accepts investments by other investment companies, it will not purchase securities of other investment companies, except 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 ( the “ 1940 Act ” ) .
Each Portfolio is a series of Voya Variable Portfolios, Inc., a Maryland corporation. Each Portfolio is managed by Voya Investments, LLC (“Voya Investments” or the “Investment Adviser”).
Portfolio shares may be classified into different classes of shares. The classes of shares of a Portfolio would be substantially the same except for different expenses, certain related rights, and certain shareholder services. All share classes of a Portfolio have a common investment objective and investment portfolio.
Fundamental Investment Policies
Fundamental investment policies contained in the SAI may not be changed without shareholder approval. Other policies and investment strategies may be changed without a shareholder vote.
Portfolio Diversification
Each Portfolio is diversified, as such term is defined in the 1940 Act. A diversified fund may not, as to 75% of its total assets, invest more than 5% of its total assets in any one issuer and may not purchase more than 10% of the outstanding voting securities of any one issuer (other than securities issued or guaranteed by the U.S. government or any of its agencies or instrumentalities, or other investment companies). A non-diversified fund is not limited by the 1940 Act in the percentage of its assets that it may invest in the obligations of a single issuer. In seeking to track the performance of the Index, a Portfolio may become “non-diversified,” as defined in the 1940 Act, as a result of a change in relative market capitalizations or index weightings of one or more components of the Index.
Investor Diversification
Although each Portfolio is designed to serve as a component of a diversified investment portfolio of securities, no single mutual fund can provide an appropriate investment program for all investors. You should evaluate a Portfolio in the context of your personal financial situation, investment objectives, and other investments.
Temporary Defensive Strategies
When the Investment Adviser or the sub-adviser (the “Sub-Adviser”) anticipates unusual market, economic, political, or other conditions, a Portfolio may temporarily depart from its principal investment strategies as a defensive measure. In such circumstances, a Portfolio may invest in securities believed to present less risk, such as cash, cash equivalents, money market fund shares and other money market instruments, fixed-income instruments that are high quality or higher quality than normal, more liquid securities, or others. While a Portfolio invests defensively, it may not achieve its investment objective. A Portfolio's defensive investment position may not be effective in protecting its value. It is impossible to predict accurately how long such alternative strategies may be utilized.

Investment Not Guaranteed
Please note your investment 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.
Shareholder Reports
Each Portfolio's fiscal year ends December 31. Copies of each Portfolio's annual and semi-annual shareholder reports are no longer sent by mail or e-mail, unless you specifically request copies of the reports. Instead, the reports are available on the Voya funds’ website (https://individuals.voya.com/literature), and you will be notified by mail each time a report is posted and provided with a website link to access the report. You may elect to receive shareholder reports and other communications from a fund electronically anytime by contacting your financial intermediary (such as a broker-dealer or bank) or, if you are a direct investor, by calling 1-800-992-0180 or by sending an e-mail request to [email protected].

MORE INFORMATION ABOUT THE PORTFOLIOS
Additional Information About the Investment Objective
Each Portfolio's investment objective is non-fundamental and may be changed by a vote of the Portfolio's Board, without shareholder approval. A Portfolio will provide 60 days' prior written notice of any change in a non-fundamental investment objective. There is no guarantee a Portfolio will achieve its investment objective.
Additional Information About Principal Investment Strategies
For a complete description of each Portfolio's principal investment strategies, please see the Portfolio's summary prospectus or the summary section of this Prospectus.
Additional Information About the Principal Risks
All mutual funds involve risk—some more than others—and there is always the chance that you could lose money or not earn as much as you hope. Each Portfolio's risk profile is largely a factor of the principal securities in which it invests and investment techniques that it uses. Below is a discussion of the principal risks associated with certain of the types of securities in which a Portfolio may invest and certain of the investment practices that a Portfolio may use. 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. For more information about these and other types of securities and investment techniques that may be used by each Portfolio, see the SAI.
Many of the investment techniques and strategies discussed in this Prospectus and in the SAI are discretionary, which means that the Investment Adviser or Sub-Adviser can decide whether to use them. A Portfolio may invest in these securities or use these techniques as part of the Portfolio's principal investment strategies. However, the Investment Adviser or Sub-Adviser may also use these investment techniques or make investments in securities that are not a part of a Portfolio's principal investment strategies.
The discussions below expand on the risks included in each Portfolio's summary section of the Prospectus. Please see the SAI for a further discussion of the principal and other investment strategies employed by each Portfolio.
China Investing Risks: The Chinese economy is generally considered an emerging and volatile market. Although China has experienced a relatively stable political environment in recent years, there is no guarantee that such stability will be maintained in the future. Significant portions of the Chinese securities markets may become rapidly illiquid because Chinese issuers have the ability to suspend the trading of their equity securities under certain circumstances, and have shown a willingness to exercise that option in response to market volatility, epidemics, pandemics, adverse economic, market or political events, and other events. Political, regulatory and diplomatic events, such as the U.S.-China “trade war” that intensified in 2018, could have an adverse effect on the Chinese or Hong Kong economies and on related investments. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States signed an Executive Order prohibiting U.S. persons from purchasing or investing in publicly-traded securities of companies identified by the U.S. government as “Communist Chinese military companies.” The list of such companies can change from time to time, and as a result of forced selling or inability to participate in an investment the Investment Adviser/Sub-Adviser otherwise believes is attractive, a Portfolio may incur losses.
•
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, a Portfolio may not be able to dispose of its China A-Shares in a timely manner, which could adversely affect the Portfolio’s performance.

MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
•
Variable Interest Entities: Many Chinese companies use a structure known as a variable interest entity (a “VIE”) to address Chinese restrictions on direct foreign investment in Chinese companies operating in certain sectors. A Portfolio’s investment exposure to VIEs may pose additional risks because the Portfolio’s investment is not made directly in the VIE (the actual Chinese operating company), but rather in a holding company domiciled outside of China (a “Holding Company”) whose interests in the business of the underlying Chinese operating company (the VIE) are established through contracts rather than through equity ownership. The VIE (which a Portfolio is restricted from owning under Chinese law) is generally owned by Chinese nationals, and the Holding Company (in which a Portfolio invests) holds only contractual rights (rather than equity ownership) relating to the VIE, typically including a contractual claim on the VIE’s profits. Shares of the Holding Company, in turn, are traded on exchanges outside of China and are available to non-Chinese investors such as a Portfolio. While the VIE structure is a longstanding practice in China, until recently, such arrangements had not been formally recognized under Chinese law. However, in late 2021, the Chinese government signaled its interest in implementing filing requirement rules that would both affirm the legality of VIE structures and regulate them. How these filing requirements will operate in practice, and what will be required for approval, remains unclear. While there is optimism that these actions will reduce uncertainty over Chinese actions on VIEs, there is also caution given how unresolved the process is. Until these rules are finalized, and potentially afterwards depending on how they are implemented, there remains significant uncertainty associated with VIE investments.
There is a risk that the Chinese government may cease to tolerate VIE structures at any time or impose new restrictions on the structure, in each case either generally or with respect to specific issuers. In such a scenario, the Chinese operating company could be subject to penalties, including revocation of its business and operating license, or the Holding Company could forfeit its interest in the business of the Chinese operating company. Further, in case of a dispute between the Holding Company investors and the Chinese owners of the VIE, the Holding Company’s contractual claims with respect to the VIE may be unenforceable in China, thus limiting the remedies and rights of Holding Company investors such as a Portfolio. Control over a VIE may also be jeopardized if a natural person who holds the equity interest in the VIE breaches the terms of the contractual arrangements, is subject to legal proceedings, or if any physical instruments or property of the VIE, such as seals, business registration certificates, financial data and licensing arrangements (sometimes referred to as “chops”), are used without authorization. In the event of such an occurrence, a Portfolio, as a foreign investor, may have little or no legal recourse. Such legal uncertainty may be exploited against the interests of the Holding Company investors such as a Portfolio.
A Portfolio will typically have little or no ability to influence the VIE through proxy voting or other means because it is not a VIE owner/shareholder. Foreign (non-U.S.) companies listed on U.S. stock exchanges, including companies using the VIE structure, could also face delisting or other ramifications for failure to meet the expectations and/or requirements of the SEC, the Public Company Accounting Oversight Board, or other U.S. regulators. Any of these risks could reduce the liquidity and value of a Portfolio’s investments in Holding Companies or render them valueless.
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.
Concentration (Index): To the extent that the Portfolio’s index “ concentrates, ” as that term is defined in the 1940 Act, in the securities of a particular industry or group of industries, the Portfolio may allocate its investments to approximately the same extent as the index. As a result, the Portfolio may be more sensitive to financial, economic, business, political, regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry or group of industries, and if securities of such industry or group of industries fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that is more broadly invested across industries.

MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.
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 fixed-income instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk. The value of a convertible security will normally fluctuate in some proportion to changes in the value of the underlying stock because of the conversion or exercise feature. However, the value of a convertible security may not increase or decrease as rapidly as the underlying stock. Convertible securities may be rated below investment grade and therefore may be subject to greater levels of credit risk and liquidity risk. In the event the issuer of a convertible security is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, a Portfolio could lose money; such events may also have the effect of reducing a Portfolio's distributable income. There is a risk that a Portfolio may convert a convertible security at an inopportune time, which may decrease the Portfolio’s returns.
Credit: A Portfolio could lose money if the issuer or guarantor of a fixed- income instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling , or is perceived (whether by market participants, rating agencies, pricing services , or otherwise) as unable or unwilling, to meet its financial obligations. Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.
Currency: To the extent that a Portfolio 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 Portfolio through foreign currency exchange transactions. Currency rates may fluctuate significantly over short periods of time. Currency rates may be affected by changes in market interest rates, intervention (or the failure to intervene) by the U.S. or foreign (non-U.S.) governments, central banks or supranational entities such as the International Monetary Fund, by the imposition of currency controls, or other political or economic developments in the U.S. or abroad.
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 a Portfolio. Therefore, the purchase of certain derivatives may have an economic leveraging effect on a Portfolio and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so a 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. Generally, derivatives are sophisticated financial instruments whose performance is derived, at least in part, from the performance of an underlying asset, reference rate, or index. Derivatives include, among other things, swap agreements, options, forward foreign currency exchange contracts, and futures. Certain derivatives in which a Portfolio may invest may be negotiated over-the-counter with a single counterparty and as a result are subject to credit risks related to the counterparty’s ability or willingness to perform its obligations; any deterioration in the counterparty’s creditworthiness could adversely affect the value of the derivative. In addition, derivatives and their underlying instruments may experience periods of illiquidity which
61

could cause a Portfolio to hold a position it might otherwise sell, or to sell a position it otherwise might hold at an inopportune time or price. A manager might imperfectly judge the direction of the market. For instance, if a derivative is used as a hedge to offset investment risk in another security, the hedge might not correlate to the market’s movements and may have unexpected or undesired results such as a loss or a reduction in gains. The U.S. government has enacted legislation that provides for new regulation of the derivatives market, including clearing, margin, reporting, and registration requirements. The European Union (and other countries outside of the European Union, including the United Kingdom) has implemented similar requirements, which may affect a Portfolio when it enters into a derivatives transaction with a counterparty organized in that country or otherwise subject to that country's derivatives regulations. Because these requirements are relatively new and evolving (and some of the rules are not yet final), their ultimate impact remains unclear. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that it will achieve that result, and, in the meantime, central clearing and related requirements expose a Portfolio to new kinds of costs and risks.
Focused Investing (Index): To the extent that the Portfolio’s benchmark or other index is substantially composed of securities in a particular industry, sector, market segment, or geographic area, the Portfolio may allocate its investments to approximately the same extent as the index as part of its investment strategy. As a result, the Portfolio may be more sensitive to financial, economic , business, political , regulatory, and other developments and conditions, including natural or other disasters, affecting issuers in a particular industry, sector, market segment, or geographic area in which the Portfolio focuses its investments, and if securities of such industry, sector, market segment, or geographic area fall out of favor, the Portfolio could underperform, or be more volatile than, a fund that has greater diversification.
•
Consumer Sectors: Investments in companies involved in the consumer sectors may be affected by changes in the domestic and international economies, exchange rates, competition, consumers’ disposable income, and consumer preferences.
•
Financial Services Sector: Investments in the financial services sector may be subject to credit risk, interest rate risk, and regulatory risk, among others. Banks and other financial institutions can be affected by such factors as downturns in the U.S. and foreign economies and general economic cycles, fiscal and monetary policy (including the effects of changes in interest rates), adverse developments in the real estate market, the deterioration or failure of other financial institutions, and changes in banking or securities regulations.
•
Health Care Sector: Investments in companies involved in the health care sector are strongly affected by worldwide scientific or technological developments. Products sold by companies in the health care sector may rapidly become obsolete and are also often dependent on access to resources and the company’s ability to receive patents from regulatory agencies. Many health care companies also are subject to significant government regulation and may be affected by changes in governmental policies. As a result, investments in health care companies include the risk that the economic prospects, and the share prices, of such companies can fluctuate dramatically.
•
Industrials Sector: Companies involved in the industrials sector include those whose businesses are dominated by one of the following activities: the manufacture and distribution of capital goods, including aerospace and defense, construction, engineering and building products, electrical equipment, and industrial machinery; the provision of commercial services and supplies, including printing, employment, environmental, and office services; and the provision of transportation services, including airlines, couriers, marine, road and rail, and transportation infrastructure. Companies involved in the industrials sector are affected by changes in the supply and demand for products and services, product obsolescence, claims for environmental damage or product liability, and general economic conditions, among other factors.
•
Technology Sector: Investments in companies involved in the technology sector are subject to significant competitive pressures, such as aggressive pricing of products or services, new market entrants, competition for market share, short product cycles due to an accelerated rate of technological developments, evolving industry standards, changing customer demands, and the potential for limited earnings and/or falling profit margins. The failure of a company to adapt to such changes could have a material adverse effect on the company’s business, results of operations, and financial condition. These companies also face the risks that new services, equipment, or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. These factors can affect the profitability of these companies and, as a result, the values of their securities. Many companies involved in the technology sector have limited operating histories, and prices of these companies’ securities historically have been more volatile than those of many other companies’ securities, especially over the short term.

Foreign (Non-U.S.) Investments/Developing and Emerging Markets: To the extent a Portfolio invests in securities of issuers in markets outside the U.S., its share price may be more volatile than if it invested in securities of issuers in the U.S. market due to, among other things, the following factors: comparatively unstable political, social and economic conditions and limited or ineffectual judicial systems; wars; comparatively small market sizes, making securities less liquid and securities prices more sensitive to the movements of large investors and more vulnerable to manipulation; governmental policies or actions, such as high taxes, restrictions on currency movements, replacement of currency, potential for default on sovereign debt, trade or diplomatic disputes, which may include the imposition of economic sanctions or other measures by the U.S. or other governments and supranational organizations, creation of monopolies, and seizure of private property through confiscatory taxation and expropriation or nationalization of company assets; incomplete, outdated, or unreliable information about securities issuers due to less stringent market regulation and accounting, auditing and financial reporting standards and practices; comparatively undeveloped markets and weak banking and financial systems; market inefficiencies, such as higher transaction costs, and administrative difficulties, such as delays in processing transactions; and fluctuations in foreign currency exchange rates, which could reduce gains or widen losses.
Economic or other sanctions imposed on a foreign (non-U.S.) country or issuer by the U.S. or on the U.S. by a foreign (non-U.S.) country, could impair a Portfolio's ability to buy, sell, hold, receive, deliver, or otherwise transact in certain securities. In addition, foreign withholding or other taxes could reduce the income available to distribute to shareholders, and special U.S. tax considerations could apply to foreign (non-U.S.) investments. Depositary receipts are subject to risks of foreign (non-U.S.) investments and might not always track the price of the underlying foreign (non-U.S.) security. 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 (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets, for such reasons as social or political unrest, heavy economic dependence on international aid, agriculture or exports (particularly commodities), undeveloped or overburdened infrastructures and legal systems, vulnerability to natural disasters, significant and unpredictable government intervention in markets or the economy, volatile currency exchange rates, currency devaluations, runaway inflation, business practices that depart from norms for developed countries, and generally less developed or liquid markets. The Public Company Accounting Oversight Board, which regulates auditors of U.S. public companies, is unable to inspect audit work papers in certain foreign (non-U.S.) countries. Investors in foreign (non-U.S.) countries often have limited rights and few practical remedies to pursue shareholder claims, including class actions or fraud claims, and the ability of the SEC, the U.S. Department of Justice and other authorities to bring and enforce actions against foreign (non-U.S.) issuers or persons is limited.
In March 2017, the United Kingdom (“UK”) formally notified the European Council of its intention to leave the EU and on January 31, 2020 withdrew from the EU (commonly known as “Brexit”). On December 30, 2020, the UK voted in favor of the UK-EU Trade and Cooperation Agreement. The agreement governs the new relationship between the UK and the EU with respect to trading goods and services but critical aspects of the relationship remain unresolved and subject to further negotiation and agreement. Brexit has resulted in volatility in European and global markets and could have negative long-term impacts on financial markets in the UK and throughout Europe. There is considerable uncertainty about the potential consequences of Brexit and how the financial markets will react. As this process unfolds, markets may be further disrupted. Given the size and importance of the UK’s economy, uncertainty about its legal, political, and economic relationship with the remaining member states of the EU may continue to be a source of instability.
In addition, the Holding Foreign Companies Accountable Act (the “HFCAA”) could cause securities of a foreign (non-U.S.) company, including American Depositary Receipts, to be delisted from U.S. stock exchanges if the company does not allow the U.S. government to oversee the auditing of its financial information. Although the requirements of the HFCAA apply to securities of all foreign (non-U.S.) issuers, the SEC has thus far limited its enforcement efforts to securities of Chinese companies. If securities are delisted, a Portfolio’s ability to transact in such securities will be impaired, and the liquidity and market price of the securities may decline. A Portfolio may also need to seek other markets in which to transact in such securities, which could increase the Portfolio’s costs.
Growth Investing: Prices of growth -oriented stocks are more sensitive to investor perceptions of the issuer ’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-oriented stocks tend to be more volatile than value-oriented stocks, and may underperform the market as a whole over any given time period. Growth-oriented stocks typically sell at relatively high valuations as compared to
63
MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
other types of securities. Securities of growth companies may be more volatile than other stocks because they usually invest a high portion of earnings in their business, and they may lack the dividends of value-oriented stocks that can cushion stock prices in a falling market. The market may not favor growth-oriented stocks or may not favor equities at all. In addition, earnings disappointments may lead to sharply falling prices because investors buy growth-oriented stocks in anticipation of superior earnings growth. Historically, growth-oriented stocks have been more volatile than value-oriented stocks.
Index Strategy (Portfolio): The index selected may underperform the overall market. To the extent a Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent a Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on a Portfolio. The correlation between a Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, a Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate.
Index Strategy for Voya Emerging Markets Index Portfolio: The index selected may underperform the overall market. To the extent a Portfolio (or a portion of the Portfolio) seeks to track an index’s performance, the Portfolio will not use defensive strategies or attempt to reduce its exposure to poor performing securities in the index. To the extent a Portfolio’s investments track its target index, the Portfolio may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on a Portfolio. The correlation between a Portfolio’s performance and index performance may be affected by the Portfolio’s expenses and the timing of purchases and redemptions of the Portfolio’s shares. In addition, a Portfolio’s actual holdings might not match the index and the Portfolio’s effective exposure to index securities at any given time may not precisely correlate. In addition, compliance with sanctions imposed by the U.S. or other governments against certain Russian issuers whose securities are included in the Portfolio’s index may impair the Portfolio’s ability to purchase, sell, receive, deliver or obtain exposure to those securities, and may interfere with the Portfolio’s ability to track its index.
Interest Rate: A rise in market interest rates generally results in a fall in the value of bonds and other fixed-income instruments; 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 to changes in market interest rates. Duration is a measure of sensitivity of the price of a fixed-income instrument to a change in interest rate. As of the date of this Prospectus, the U.S. is experiencing a rising market interest rate environment, which may increase a Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that a Portfolio invests in fixed-income instruments, 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 a Portfolio 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. Negative or very low interest rates could magnify the risks associated with changes in interest rates. In general, changing interest rates, including rates that fall below zero, could have unpredictable effects on markets and may expose fixed-income and related markets to heightened volatility. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose fixed-income and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact a Portfolio’s operations and return potential.
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 a Portfolio. Proprietary models used by the Sub-Adviser to evaluate securities or securities markets are based on the Sub-Adviser’s understanding of the interplay of market factors and do not assure successful investment. The markets, or the price of individual securities, may be affected by factors
64
MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
not foreseen in the construction of the models. 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, a 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 a 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 a 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 a Portfolio 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-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization 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, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.
Market Disruption and Geopolitical: A 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 a 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.) 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 a Portfolio’s investments. Any of these occurrences could disrupt the operations of a Portfolio and of the Portfolio’s service providers.
Mid-Capitalization Company: Investments in mid-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, smaller size, limited markets, and financial resources, narrow product lines, less management depth, and more reliance
65
MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
on key personnel. Consequently, the securities of mid-capitalization companies may have limited market stability and may be subject to more abrupt or erratic market movements than securities of larger, more established growth companies or the market averages in general.
Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of , the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of fixed-income instruments. Small movements in interest rates (both increases and decreases) may quickly and significantly reduce the value of certain asset-backed securities. The value of longer-term securities generally changes more in response to changes in market interest rates than shorter-term securities.
These securities may be affected significantly by government regulation, market interest rates, market perception of the creditworthiness of an issuer servicer, and loan-to-value ratio of the underlying assets. During an economic downturn, the mortgages, commercial or consumer loans, trade or credit card receivables, installment purchase obligations, leases, or other debt obligations underlying an asset-backed security may experience an increase in defaults as borrowers experience difficulties in repaying their loans which may cause the valuation of such securities to be more volatile and may reduce the value of such securities. These risks are particularly heightened for investments in asset-backed securities that contain sub-prime loans, which are loans made to borrowers with weakened credit histories and often have higher default rates.
Non-Diversification (Index): Depending on the composition of the Index, a Portfolio may at any time, with respect to 75% of a Portfolio’s total assets, invest more than 5% of the value of its total assets in the securities of any one issuer. As a result, a Portfolio would at that time be non-diversified, as defined in the 1940 Act. A non-diversified investment company may invest a greater percentage of its assets in the securities of a single issuer than may a diversified investment company. A non-diversified investment company is subject to the risks of focusing investments in a small number of issuers, including being more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio might be. A Portfolio may significantly underperform other mutual funds or investments due to the poor performance of relatively few securities, or even a single security, and a Portfolio’s shares may experience significant fluctuations in value.
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 a Portfolio’s expenses. The investment policies of the other investment companies may not be the same as those of a Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which a Portfolio is typically subject. ETFs are exchange-traded investment companies that are, in many cases, designed to provide investment results corresponding to an index. Additional risks of investments in ETFs include that: (i) an active trading market for an ETF’s shares may not develop or be maintained; or (ii) trading may be halted if the listing exchanges’ officials deem such action appropriate, the shares are delisted from an exchange, or the activation of market-wide “circuit breakers” (which are tied to large decreases in stock prices) halts trading of an ETF’s shares. Other investment companies include Holding Company Depositary Receipts (“HOLDRs”). Because HOLDRs concentrate in the stocks of a particular industry, trends in that industry may have a dramatic impact on their value. 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.
Prepayment and Extension: Many types of fixed-income instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a fixed-income instrument will pay back the principal earlier than expected. This risk is heightened in a falling market interest rate environment. Prepayment may expose a Portfolio to a lower rate of return upon reinvestment of principal. Also, if a fixed-income instrument subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Extension risk is the risk that the issuer of a fixed-income instrument will pay back the principal later than expected. This risk is heightened in a rising
66
MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
market interest rate environment. This may negatively affect performance, as the value of the fixed-income instrument decreases when principal payments are made later than expected. Additionally, a Portfolio may be prevented from investing proceeds it would have received at a given time at the higher prevailing interest rates.
Real Estate Companies and Real Estate Investment Trusts: Investing in real estate companies and REITs may subject a 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. Some REITs may invest in a limited number of properties, in a narrow geographic area or in a single property type, which increases the risk that a Portfolio could be unfavorably affected by the poor performance of a single investment or investment type. These companies are also sensitive to factors such as changes in real estate values and property taxes, market interest rates, cash flow of underlying real estate assets, supply and demand, and the management skill and creditworthiness of the issuer. Borrowers could default on or sell investments the REIT holds, which could reduce the cash flow needed to make distributions to investors. 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. A 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, a Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that a Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that a 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 a Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of a Portfolio’s other risks.
A Portfolio seeks to minimize investment risk by limiting the investment of cash collateral to high-quality instruments of short maturity. In the event of a borrower default, a Portfolio will be protected to the extent the Portfolio is able to exercise its rights in the collateral promptly and the value of such collateral is sufficient to purchase replacement securities. A Portfolio is protected by its securities lending agent, which has agreed to indemnify the Portfolio from losses resulting from borrower default.
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.
U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk. Some U.S. government securities are backed by the full faith and credit of the U.S. government and are guaranteed as to both principal and interest by the U.S. Treasury. These include direct obligations of the U.S. Treasury such as U.S. Treasury notes, bills, and bonds, as well as indirect obligations including certain securities of the Government National Mortgage Association, the Small Business Administration, and the Farmers Home Administration, among others. Other U.S. government securities are not direct obligations of the U.S. Treasury, but rather are backed by the ability to borrow directly from the U.S. Treasury, including certain securities of the Federal Financing Bank, the Federal Home Loan Bank, and the U.S. Postal Service. Other U.S. government securities are backed solely by the credit of the agency or instrumentality itself and are neither guaranteed nor insured by the U.S. government and, therefore, involve greater risk. These include securities issued by the Federal Home Loan Bank, the Federal Home Loan Mortgage Corporation, and the Federal Farm Credit Bank, among others. Consequently, the investor must look principally to the agency issuing or guaranteeing the obligation for ultimate repayment. No assurance can be given that the U.S. government would provide financial support to such agencies if it is not obligated to do so by law. The impact of greater governmental scrutiny into the operations of certain agencies and government-sponsored enterprises may adversely affect the value of securities issued by these entities. U.S. government securities may be subject to price declines due to changing market interest rates. From time to time, uncertainty regarding the status of negotiations in the U.S. government to increase the statutory debt
67
MORE INFORMATION ABOUT THE PORTFOLIOS (continued)
ceiling could increase the risk that the U.S. government may default on payments on certain U.S. government securities, cause the credit rating of the U.S. government to be downgraded, increase volatility in the stock and bond markets, result in higher interest rates, reduce prices of U.S. Treasury securities, and/or increase the costs of various kinds of debt. If a U.S. government-sponsored entity is negatively impacted by legislative or regulatory action (or lack thereof), is unable to meet its obligations, or its creditworthiness declines, the performance of a Portfolio that holds securities of the entity will be adversely impacted.
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 a Portfolio holds may not reach their full values. Risks associated with value investing include that a security that is perceived by the manager to be undervalued may actually be appropriately priced and, thus, may not appreciate and provide anticipated capital growth. The market may not favor value-oriented securities and may not favor equities at all. During those periods, a Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented securities may underperform other funds that invest more broadly.
When-Issued, Delayed Delivery and Forward Commitment Transactions : When - issued , delayed delivery and forward commitment transactions involve the risk that the security a Portfolio buys will lose value prior to its delivery. These transactions may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing a Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of a Portfolio’s other risks. There also is the risk that the security will not be issued or that the other party will not meet its obligation. If this occurs, a Portfolio loses both the investment opportunity for the assets it set aside to pay for the security and any gain in the security’s price.
Further Information About Principal Risks
The following provides additional information about certain aspects of the principal risks described above.
Counterparty: The entity with which a Portfolio conducts portfolio-related business (such as trading or securities lending), or that underwrites, distributes or guarantees investments or agreements that the Portfolio owns or is otherwise exposed to, may refuse or may become unable to honor its obligations under the terms of a transaction or agreement. As a result, the Portfolio may sustain losses and be less likely to achieve its investment objective. These risks may be greater when engaging in over-the-counter transactions or when a Portfolio conducts business with a limited number of counterparties.
Duration: One measure of risk for fixed-income instruments is duration. Duration measures the sensitivity of a bond’s price to market interest rate movements and is one of the tools used by a portfolio manager in selecting fixed-income instruments. Duration measures the average life of a bond on a present value basis by incorporating into one measure a bond’s yield, coupons, final maturity and call features. As a point of reference, the duration of a non-callable 7% coupon bond with a remaining maturity of 5 years is approximately 4.5 years and the duration of a non-callable 7% coupon bond with a remaining maturity of 10 years is approximately 8 years. Material changes in market interest rates may impact the duration calculation. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%.
Inflation: Inflation risk is the risk that the value of assets or income from a Portfolio's investments will be worth less in the future as inflation decreases the value of payments at future dates. As inflation increases, the value of a Portfolio’s portfolio could decline. Inflation rates may change frequently and drastically as a result of various factors and a Portfolio's investments may not keep pace with inflation, which may result in losses to the Portfolio’s investors or adversely affect the value of shareholders' investments in the Portfolio. Inflation has recently increased, and it cannot be predicted whether it may decline.
Investment by Other Funds: Certain funds -of-funds, including some Voya funds, may invest in a Portfolio. If investments by these other funds result in large inflows or outflows of cash from a Portfolio, a Portfolio could be required to sell securities or invest cash at times, or in ways, that could, among other things, negatively impact its performance, speed the realization of capital gains, increase its portfolio turnover , affect the liquidity of its portfolio , or increase transaction costs. The manager will monitor transactions by such funds-of-funds and will attempt to minimize any

adverse effects these transactions may have on a Portfolio. If shares of a Portfolio are purchased by another fund in reliance on Section 12(d)(1)(G) of the 1940 Act or Rule 12d1-4 thereunder and the Portfolio purchases shares of other investment companies in reliance on Rule 12d1-4, the Portfolio will not be able to make new investments in other funds, including private funds, if, as a result of such investment, more than 10% of the Portfolio’s assets would be invested in other funds or private funds, subject to certain exceptions.
Leverage: Certain transactions and investment strategies may give rise to leverage. Such transactions and investment strategies include, but are not limited to: borrowing, dollar rolls, reverse repurchase agreements, loans of portfolio securities, short sales, and the use of when-issued, delayed delivery or forward commitment transactions. The use of certain derivatives may also increase leveraging risk and, in some cases, adverse changes in the value or level of a derivative’s underlying asset, rate, or index may result in potentially unlimited losses. The use of leverage may exaggerate any increase or decrease in the net asset value, causing a Portfolio to be more volatile than if the Portfolio had not been leveraged. The use of leverage may increase expenses and increase the impact of a Portfolio’s other risks. The use of leverage may cause a Portfolio to liquidate portfolio positions when it may not be advantageous to do so to satisfy its obligations or to meet regulatory requirements resulting in increased volatility of returns.
Manager: A Portfolio employing a “ passive management ” approach designed to track the performance of an index is subject to manager risk when the Investment Adviser, the Sub-Adviser or each individual portfolio manager uses statistical techniques to manage the Portfolio. These statistical techniques can involve investing in a representative sample of securities that collectively has an investment profile similar to the applicable Index. The securities selected are expected to have, in the aggregate, investment characteristics (based on factors such as market value and industry weightings), fundamental characteristics (such as return variability, duration, maturity, credit ratings and yield) and liquidity measures similar to those of an applicable Index. As a result, the Portfolio is subject to the risk that the manager’s investment strategy may not produce the intended results. A Portfolio may or may not hold all of the securities in the Index. Because a Portfolio may use statistical techniques to implement its strategy, it can be expected to have a larger tracking error than if it used a replication indexing strategy.
Operational: A Portfolio, its service providers, and other market participants increasingly depend on complex information technology and communications systems to conduct business functions. These systems are subject to a number of different threats or risks that could adversely affect a Portfolio and its shareholders, despite the efforts of a Portfolio and its service providers to adopt technologies, processes, and practices intended to mitigate these risks. Cyber-attacks, disruptions, or failures that affect a Portfolio’s service providers, counterparties, market participants, or issuers of securities held by a Portfolio may adversely affect a Portfolio and its shareholders, including by causing losses or impairing the Portfolio’s operations. Information relating to a Portfolio’s investments has been and will in the future be delivered electronically, which can give rise to a number of risks, including, but not limited to, the risks that such communications may not be secure and may contain computer viruses or other defects, may not be accurately replicated on other systems, or may be intercepted, deleted or interfered with, without the knowledge of the sender or the intended recipient.

For information regarding the basis for the Board’s approval of the investment advisory and investment sub-advisory relationships, please refer to the Portfolios’ annual shareholder report which covers the one-year period ending December 31, 2022.
The Sub-Adviser and Portfolio Managers
The Investment Adviser has engaged a sub-adviser to provide the day-to-day management of each Portfolio's portfolio. The Sub-Adviser is an affiliate of the Investment Adviser.
The Investment Adviser acts as a “manager-of-managers” for each Portfolio. The Investment Adviser has ultimate responsibility, subject to the oversight of each Portfolio’s Board, to oversee any sub-advisers and to recommend the hiring, termination, or replacement of sub-advisers. Each Portfolio and the Investment Adviser have received exemptive relief from the SEC which permits the Investment Adviser, with the approval of the Board but without obtaining shareholder approval, to enter into or materially amend a sub-advisory agreement with sub-advisers that are not affiliated with the Investment Adviser (“non-affiliated sub-advisers”) as well as sub-advisers that are indirect or direct, wholly-owned subsidiaries of the Investment Adviser or of another company that indirectly or directly wholly owns the Investment Adviser (“wholly-owned sub-advisers”).
Consistent with the “manager-of-managers” structure, the Investment Adviser delegates to the Sub-Adviser(s) of each Portfolio the responsibility for day-to-day investment management, subject to the Investment Adviser’s oversight. The Investment Adviser is responsible for, among other things, monitoring the investment program and performance of
71
MANAGEMENT OF THE PORTFOLIOS (continued)
the Sub-Adviser(s). Pursuant to the exemptive relief, the Investment Adviser, with the approval of the Board, has the discretion to terminate any sub-adviser (including terminating a non-affiliated sub-adviser and replacing it with a wholly-owned sub-adviser), and to allocate and reallocate a Portfolio’s assets among other sub-advisers.
The Investment Adviser’s selection of sub-advisers presents conflicts of interest. The Investment Adviser will have an economic incentive to select sub-advisers that charge the lowest sub-advisory fees, to select sub-advisers affiliated with it, or to manage a portion of a Portfolio itself. The Investment Adviser may retain an affiliated sub-adviser (or delay terminating an affiliated sub-adviser) in order to help that sub-adviser achieve or maintain scale in an investment strategy or increase its assets under management. The Investment Adviser may select or retain an affiliated sub-adviser even in cases where another potential sub-adviser or an existing sub-adviser might charge a lower fee or have more favorable historical investment performance.
In the event that the Investment Adviser exercises its discretion to replace a sub-adviser or appoint a new sub-adviser, the Portfolio will provide shareholders with information about the new sub-adviser and the new sub-advisory agreement within 90 days. The replacement of an existing sub-adviser or appointment of a new sub-adviser may be accompanied by a change to the name of the Portfolio and a change to the investment strategies of the Portfolio.
A sub-advisory agreement can be terminated by the Investment Adviser, a Portfolio’s Board, or the Sub - Adviser , provided that the conditions of such termination, as set forth in the agreement, are met. In addition, a sub-advisory agreement may be terminated by a Portfolio’s shareholders. In the event a sub-advisory agreement is terminated, the Sub-Adviser(s) may be replaced, subject to any regulatory requirements, or the Investment Adviser may assume day-to-day investment management of the Portfolio.
The “manager-of-managers” structure and reliance on the exemptive relief has been approved by each Portfolio’s shareholders.

The Distributor is an indirect subsidiary of Voya Financial, Inc. and is an affiliate of the Investment Adviser. The Distributor’s principal office is located at 7337 East Doubletree Ranch Road, Suite 100, Scottsdale, Arizona 85258. See “Principal Underwriter” in the SAI.

Contractual Arrangements
Each Portfolio has contractual arrangements with various service providers, which may include, among others, investment advisers, distributors, custodians and fund accounting agents, shareholder service providers, and transfer agents, who provide services to each Portfolio. Shareholders are not parties to, or intended (“third-party”) beneficiaries of, any of those contractual arrangements, and those contractual arrangements are not intended to create in any individual
73
MANAGEMENT OF THE PORTFOLIOS (continued)
shareholder or group of shareholders any right to enforce them against the service providers or to seek any remedy under them against the service providers, either directly or on behalf of a Portfolio. This paragraph is not intended to limit any rights granted to shareholders under federal or state securities laws.
74
HOW SHARES ARE PRICED
Each Portfolio is open for business every day the New York Stock Exchange (the “NYSE”) opens for regular trading (each such day, a “Business Day”). The net asset value (the “NAV”) per share for each class of each Portfolio is determined each Business Day as of the close of the regular trading session (“Market Close”), as determined by the Consolidated Tape Association (the “CTA”), the central distributor of transaction prices for exchange-traded securities (normally 4:00 p.m. Eastern time unless otherwise designated by the CTA). The NAV per share of each class of each Portfolio is calculated by taking the value of the Portfolio’s assets attributable to that class, subtracting the Portfolio’s liabilities attributable to that class, and dividing by the number of shares of that class that are outstanding. On days when a Portfolio is closed for business, Portfolio shares will not be priced, and the Portfolio will not process purchase or redemption orders. To the extent a Portfolio’s assets are traded in other markets on days when the Portfolio does not price its shares, the value of the Portfolio’s assets will likely change and you will not be able to purchase or redeem shares of the Portfolio.
Portfolio holdings for which market quotations are readily available are valued at market value. Investments in open-end registered investment companies that do not trade on an exchange are valued at the end of day NAV per share. The prospectuses of the open-end registered investment companies in which each Portfolio may invest explain the circumstances under which they will use fair value pricing and the effects of using fair value pricing. Foreign (non-U.S.) securities’ prices are converted into U.S. dollar amounts using the applicable exchange rates as of Market Close.
When a market quotation for a portfolio security is not readily available or is deemed unreliable (for example, when trading has been halted or there are unexpected market closures or other material events that would suggest that the market quotation is unreliable) and for purposes of determining the value of other portfolio holdings, the portfolio holding is priced at its fair value. The Board has designated the Investment Adviser, as the valuation designee, to make fair value determinations in good faith. In determining the fair value of a Portfolio’s portfolio holdings, the Investment Adviser, pursuant to its fair valuation policy, may consider inputs from pricing service providers, broker-dealers, or a Portfolio’s Sub-Adviser(s). Issuer specific events, transaction price, position size, nature and duration of restrictions on disposition of the security, market trends, bid/ask quotes of brokers, and other market data may be reviewed in the course of making a good faith determination of the fair value of a portfolio holding. Because trading hours for certain foreign ( non-U.S.) securities end before Market Close, closing market quotations may become unreliable. The prices of foreign ( non - U.S.) securities will generally be adjusted based on inputs from an independent pricing service that are intended to reflect valuation changes through Market Close. Because of the inherent uncertainties of fair valuation, the values used to determine each Portfolio’s NAV may materially differ from the value received upon actual sale of those investments. Thus, fair valuation may have an unintended dilutive or accretive effect on the value of shareholders’ investments in each Portfolio.
When your Variable Contract or Qualified Plan is buying shares of a Portfolio, it will pay the NAV that is next calculated after the order from the Variable Contract owner or Qualified Plan participant is received in proper form. When the Variable Contract owner or Qualified Plan participant is selling shares, it will normally receive the NAV that is next calculated after the order form is received from the Variable Contract owner or Qualified Plan participant in proper form. Investments will be processed at the NAV next calculated after an order is received and accepted by a Portfolio or its designated agent. In order to receive that day's price, your order must be received by Market Close.
75
HOW TO BUY AND SELL SHARES
Each Portfolio's shares may be offered to insurance company separate accounts serving as investment options under Variable Contracts, Qualified Plans outside the separate account context, custodial accounts, certain investment advisers and their affiliates in connection with the creation or management of a Portfolio, other investment companies (as permitted by the 1940 Act), and other investors as permitted by the diversification and other requirements of section 817(h) of the Internal Revenue Code of 1986, as amended (the “Code”) and the underlying U.S. Treasury Regulations.
Each Portfolio may not be available as an investment option in your Variable Contract, through your Qualified Plan, or other investment company. 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 redemptions from, an investment option corresponding to a Portfolio and any fees that may apply. Participating insurance companies and certain other designated organizations are authorized to receive purchase orders on each Portfolio's behalf.
Each Portfolio currently does not foresee any disadvantages to investors if it serves as an investment option for Variable Contracts and if it offers its shares directly to Qualified Plans and other permitted investors. However, it is possible that the interests of Variable Contracts owners, plan participants, and other permitted investors for which a Portfolio serves as an investment option might, at some time, be in conflict because of differences in tax treatment or other considerations. The Board directed the Investment Adviser to monitor events to identify any material conflicts between Variable Contract owners, plan participants, and other permitted investors and would have to determine what action, if any, should be taken in the event of such conflict. If such a conflict occurred, an insurance company participating in a Portfolio might be required to redeem the investment of one or more of its separate accounts from the Portfolio or a Qualified Plan, investment company, or other permitted investor might be required to redeem its investment, which might force the Portfolio to sell securities at disadvantageous prices. Each Portfolio may discontinue sales to a Qualified Plan and require plan participants with existing investments to redeem those investments if the Qualified Plan loses (or in the opinion of the Investment Adviser, is at risk of losing) its Qualified Plan status.
Each Portfolio reserves the right to suspend the offering of shares or to reject any specific purchase order. Each Portfolio may suspend redemptions or postpone payments when the NYSE is closed or when trading is restricted for any reason or under emergency circumstances as determined by the SEC.
Distribution Plans and Shareholder Service Plans
Each Portfolio listed in the table below has a distribution and shareholder service plan (the “12b-1 Plan”) in accordance with Rule 12b-1 under the 1940 Act for Class ADV and Class S2 shares. These payments are made to the Distributor on an ongoing basis as compensation for services the Distributor provides and expenses it bears in connection with the marketing and other fees to support the sale and distribution of Class ADV and Class S2 shares and for shareholder services provided by securities dealers (including the Distributor) and other financial intermediaries and plan administrators that provide administrative services relating to Class ADV and Class S2 shares and their shareholders, including Variable Contract owners or Qualified Plan participants with interests in the Portfolios. The annual distribution and shareholder service fees under the 12b-1 Plan for Class ADV shares may equal up to 0.50% (0.25% for distribution fees and 0.25% for shareholder service fees), and the annual distribution and shareholder service fees under the 12b-1 Plan for Class S2 shares may equal up to 0.40% (0.15% for distribution fees and 0.25% for shareholder service fees) of a Portfolio’s average daily net assets attributable to each of its Class ADV and Class S2 shares. The Distributor has contractually agreed to waive 0.01% of the distribution fee for Class ADV shares of Voya International Index Portfolio through May 1, 2024.
Each Portfolio listed in the table below has a distribution/shareholder service plan (“Distribution/Shareholder Service Plan”) in accordance with Rule 12b-1 under the 1940 Act for Class S shares. These payments are made to the Distributor on an ongoing basis as compensation for services the Distributor provides and expenses it bears in connection with the marketing and other fees to support the sale and distribution of Class S shares and for shareholder services provided by securities dealers (including the Distributor) and other financial intermediaries and plan administrators that provide administrative services relating to Class S shares and their shareholders, including Variable Contract owners or Qualified Plan participants with interests in the Portfolios. The annual distribution/shareholder service fees under the Distribution/Shareholder Service Plan may equal up to 0.25% of the average daily net assets of each Portfolio.
Because these distribution and shareholder service fees are paid out of a Portfolio’s assets on an ongoing basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges.

FREQUENT TRADING - MARKET TIMING
Each Portfolio is intended for long-term investment and not as a short-term trading vehicle. Accordingly, organizations or individuals that use market timing investment strategies and make frequent transfers should not purchase shares of a Portfolio. Shares of each Portfolio are primarily sold through omnibus account arrangements with financial intermediaries, as investment options for Variable Contracts issued by insurance companies and as investment options for Qualified Plans. Omnibus accounts generally do not identify customers' trading activity on an individual basis. The Investment Adviser or affiliated entities have agreements which require such intermediaries to provide detailed account information, including trading history, upon request of a Portfolio.
The Board has made a determination not to adopt a separate policy for each Portfolio with respect to frequent purchases and redemptions of shares by a Portfolio’s shareholders, but rather to rely on the financial intermediaries to monitor frequent, short-term trading within a Portfolio by its customers. You should review the materials provided to you by your financial intermediary including, in the case of a Variable Contract, the prospectus that describes the contract or, in the case of a Qualified Plan, the plan documentation for its policies regarding frequent, short-term trading. With trading information received as a result of these agreements, a Portfolio may make a determination that certain trading activity is harmful to the Portfolio and its shareholders, even if such activity is not strictly prohibited by the intermediaries' excessive trading policy. As a result, a shareholder investing directly or indirectly in a Portfolio may have their trading privileges suspended without violating the stated excessive trading policy of the intermediary. Each Portfolio reserves the right, in its sole discretion and without prior notice, to reject, restrict, or refuse purchase orders whether directly or by exchange including purchase orders that have been accepted by a financial intermediary. Each Portfolio seeks assurances from the financial intermediaries that they have procedures adequate to monitor and address frequent, short-term trading. There is, however, no guarantee that the procedures of the financial intermediaries will be able to curtail frequent, short-term trading activity.
Each Portfolio believes that market timing or frequent, short-term trading in any account, including a Variable Contract or Qualified Plan account, is not in the best interest of the Portfolio or its shareholders. Due to the disruptive nature of this activity, it can adversely impact the ability of the Investment Adviser or the Sub-Adviser (if applicable) to invest assets in an orderly, long-term manner. Frequent trading can disrupt the management of a Portfolio and raise their expenses through: increased trading and transaction costs; forced and unplanned portfolio turnover; lost opportunity costs; and large asset swings that decrease the Portfolio's ability to provide maximum investment return to all shareholders. This in turn can have an adverse effect on a Portfolio's performance.
Portfolios that invest in foreign (non-U.S.) securities may present greater opportunities for market timers and thus be at a greater risk for excessive trading. If an event occurring after the close of a foreign market, but before the time a Portfolio computes its current NAV, causes a change in the price of the foreign (non-U.S.) security and such price is not reflected in its current NAV, investors may attempt to take advantage of anticipated price movements in securities held by a Portfolio based on such pricing discrepancies. This is often referred to as “price arbitrage.” Such price arbitrage opportunities may also occur in portfolios which do not invest in foreign (non-U.S.) securities. For example, if trading in a security held by a Portfolio is halted and does not resume prior to the time it calculates its NAV such “stale pricing” presents an opportunity for investors to take advantage of the pricing discrepancy. Similarly, portfolios that hold thinly-traded securities, such as certain small-capitalization securities, may be exposed to varying levels of pricing arbitrage. Each Portfolio has adopted fair valuation policies and procedures intended to reduce its exposure to price arbitrage, stale pricing and other potential pricing discrepancies. However, to the extent that a Portfolio does not immediately reflect these changes in market conditions, short-term trading may dilute the value of the Portfolio’s shares which negatively affects long-term shareholders.
The following transactions are excluded when determining whether trading activity is excessive:
•
Rebalancing to facilitate fund-of-fund arrangements or a Portfolio’s systematic exchange privileges; and
•
Purchases or sales initiated by certain other funds in the Voya family of funds.
Although the policies and procedures known to a Portfolio that are followed by the financial intermediaries that use the Portfolio and the monitoring by the Portfolio are designed to discourage frequent, short-term trading, none of these measures can eliminate the possibility that frequent, short-term trading activity in the Portfolio will occur. Moreover, decisions about allowing trades in a Portfolio may be required. These decisions are inherently subjective, and will be made in a manner that is in the best interest of a Portfolio's shareholders.
78
PAYMENTS TO FINANCIAL INTERMEDIARIES
Voya mutual funds may be offered as investment options in Variable Contracts issued by affiliated and non-affiliated insurance companies and in Qualified Plans. Fees derived from a Portfolio's Distribution and/or Service Plans (if applicable) may be paid to insurance companies, broker-dealers, and companies that service Qualified Plans for selling the Portfolio's shares and/or for servicing shareholder accounts. Fees derived from a Portfolio’s Service Plan may be paid to insurance companies, broker-dealers, and companies that service Qualified Plans for servicing shareholder accounts. Shareholder services may include, among other things, administrative, record keeping, or other services that insurance companies or Qualified Plans provide to the clients who use a Portfolio as an investment option. In addition, the Investment Adviser, Distributor, or their affiliated entities, out of their own resources and without additional cost to a Portfolio or its shareholders, may pay additional compensation to these insurance companies, broker-dealers, or companies that service Qualified Plans. The Investment Adviser, Distributor, or affiliated entities of a Portfolio may also share their profits with affiliated insurance companies or other Voya entities through inter-company payments.
For non-affiliated insurance companies and Qualified Plans, payments from a Portfolio's Distribution and/or Service Plans (if applicable) as well as payments (if applicable) from the Investment Adviser and/or Distributor generally are based upon an annual percentage of the average net assets held in a Portfolio by those companies. Payments to financial intermediaries by the Distributor or its affiliates or by a Portfolio may provide an incentive for insurance companies or Qualified Plans to make a Portfolio available through Variable Contracts or Qualified Plans over other mutual funds or products.
As of the date of this Prospectus, the Distributor has entered into agreements with the following non-affiliated insurance companies: C.M. Life Insurance Company, First Security Benefit Life Insurance and Annuity Company of New York, Lexington Life Insurance Company, Lincoln Financial Group, Massachusetts Mutual Life Insurance Company, New York Life Insurance and Annuity Corporation, Security Benefit Life Insurance Company, Security Equity Life Insurance Company, Symetra Life Insurance Company, TIAA Life Insurance Company, Transamerica Life Insurance Company, Transamerica Financial Life Insurance Company, and Union Securities. Except as discussed in further detail below, the fees payable under these agreements are for compensation for providing distribution and/or shareholder services for which the insurance companies are paid at annual rates that range from 0.00% to 0.50%. This is computed as a percentage of the average aggregate amount invested in the Portfolio by Variable Contract holders through the relevant insurance company's Variable Contracts.
The insurance companies issuing Variable Contracts or Qualified Plans that use a Portfolio as an investment option may also pay fees to third parties in connection with distribution of the Variable Contracts and for services provided to Variable Contract owners. Entities that service Qualified Plans may also pay fees to third parties to help service the Qualified Plans or the accounts of their participants. Neither a Portfolio, the Investment Adviser, nor the Distributor are parties to these arrangements. Variable Contract owners should consult the prospectus and statement of additional information for their Variable Contracts for a discussion of these payments and should consult with their agent or broker. Qualified Plan participants should consult with their pension servicing agent.
Ultimately, the agent or broker selling the Variable Contract to you could have a financial interest in selling you a particular product to increase the compensation they receive. Please make sure you read fully each prospectus and discuss any questions you have with your agent or broker.
79
DIVIDENDS, DISTRIBUTIONS, AND TAXES
Dividends and Distributions
Each Portfolio generally distributes most or all of its net earnings in the form of dividends, consisting of net investment income and capital gains distributions. Each Portfolio distributes capital gains, if any, annually. Each Portfolio (except Voya U.S. Bond Index Portfolio) also declares dividends and pays dividends consisting of net investment income, if any, annually. Voya U.S. Bond Index Portfolio declares dividends daily and pays dividends consisting of net investment income, if any, monthly.
All dividends and capital gains distributions will be automatically reinvested in additional shares of a Portfolio at the NAV of such shares on the payment date unless a participating insurance company’s separate account is permitted to hold cash and elects to receive payment in cash.
From time to time a portion of a Portfolio’s distributions may constitute a return of capital. To comply with federal tax regulations, each Portfolio may also pay an additional capital gains distribution.
Tax Matters
Holders of Variable Contracts should refer to the prospectus for their contracts for information regarding the tax consequences of owning such contracts and should consult their tax advisers before investing.
Each Portfolio intends to qualify as a regulated investment company (“RIC”) for federal income tax purposes by satisfying the requirements under Subchapter M of the Code, including requirements with respect to diversification of assets, distribution of income and sources of income. As a RIC, a Portfolio generally will not be subject to tax on its net investment company taxable income and net realized capital gains that it timely distributes to its shareholders.
Each Portfolio also intends to comply with the diversification requirements of Section 817(h) of the Code and the underlying regulations for Variable Contracts so that owners of these contracts should not be subject to federal tax on distributions of dividends and income from the Portfolio to the insurance company's separate accounts.
Since the sole shareholders of each Portfolio will be separate accounts or other permitted investors, no discussion is included herein as to the federal income tax consequences at the shareholder level. For information concerning the federal income tax consequences to purchasers of the Variable Contracts, see the prospectus for the contract.
See the SAI for further information about tax matters.
The tax status of your investment in a Portfolio depends upon the features of your Variable Contract. For further information, please refer to the prospectus for the Variable Contract.

FINANCIAL HIGHLIGHTS
The financial highlights table is intended to help you understand a Portfolio's financial performance for the periods shown. Certain information reflects the financial results for a single share. The total returns in the table represent the rate of return that an investor would have earned or lost on an investment in a Portfolio (assuming reinvestment of all dividends and/or distributions). The information for the fiscal years ended December 31, 2022, December 31, 2021, and December 31, 2020 has been audited by Ernst & Young LLP, whose report, along with a Portfolio’s financial statements, is included in a Portfolio’s Annual Report, which is available upon request. The information for the prior fiscal years or periods was audited by a different independent public accounting firm.

ACCOMPANYING NOTES TO FINANCIAL HIGHLIGHTS
(1)
Total return is calculated assuming reinvestment of all dividends, capital gain distributions, and return of capital distributions, if any, at net asset value and does not reflect the effect of insurance contract charges.
(2)
Ratios do not include fees and expenses charged under the variable annuity contract or variable life insurance policy.
(3)
Ratios reflect operating expenses of a Portfolio. Expenses before reductions/additions do not reflect amounts reimbursed or recouped by the Investment Adviser and/or the Distributor or reductions from brokerage service arrangements or other expense offset arrangements and do not represent the amount paid by a Portfolio during periods when reimbursements or reductions occur. Expenses net of fee waivers reflect expenses after reimbursement by the Investment Adviser and/or the Distributor or recoupment of previously reimbursed fees by the Investment Adviser, but prior to reductions from brokerage service arrangements or other expense offset arrangements. Expenses net of all reductions/additions represent the net expenses paid by a Portfolio. Net investment income (loss) is net of all such additions or reductions.
